For decades, the United States (U.S.) Department of Defense (DoD) has developed, deployed, and operated hundreds of different types of systems as components of systems-of-systems. Achieving and maintaining joint systems-of-systems interoperability as new systems are added is a constant problem. The Army, Navy, U.S. Marine Corps, and Air Force each develop requirements, budgets, and acquire, field and operate systems that function as part of joint systems-of-systems. Technology and threats are rapidly evolving. These globally deployed systems and systems-of-systems employed by combatant commanders must be continuously modernized or risk becoming obsolete, resulting in potential mission failure and loss of life.

Using a wireless telecommunications interface standard case study, this research developed a unique method of planning systems-of-systems modernization using a system dynamics (SD) approach. This approach: a) accounts for key factors that influence the dynamic behavior of systems-of-systems modernization, impacting the ability to modernize systems-of-systems, and b) enables what-if analysis, and decision-making support of systems-of-systems modernization planning options. This research used a mixed-methods approach to demonstrate that the SD model is measurably superior to past practice. Quantitative statistical analysis was performed on 20 years’ (2001–2020) of data. A qualitative, scenario-based approach was used to develop an SD model. The results demonstrate that engineers, managers, and senior decision makers in the DoD can realize statistically significant gains by using an SD model to develop and explore systems-of-systems modernization planning options. This research’s original contribution to knowledge is the development and validation of an SD model for planning systems-of-systems modernization using a mixed-methods research approach.

• Publication RF Amplification and Filtering Techniques for Cellular Receivers ( University College Dublin. School of Electrical and Electronic Engineering, 2021 ) Bozorg, Amir   The usage of various wireless standards, such as Bluetooth, Wi-Fi, GPS, and 4G/5G cellular, has been continually increasing. In order to utilize the frequency bands efficiently and to support new communication standards with lower power consumption, lower occupied volume and at reduced costs, multimode transceivers, software defined radios (SDRs), cognitive radios, etc., have been actively investigated. Broadband behavior of a wireless receiver is typically defined by its front-end low-noise amplifier (LNA), whose design must consider trade-offs between input matching, noise figure (NF), gain, bandwidth, linearity, and voltage headroom in a given process technology. Moreover, monolithic RF wireless receivers have been trending toward high intermediatefrequency (IF) or superhetrodyne radios thanks to recent breakthroughs in silicon integration of band-pass channel-select filters. The main motivation is to avoid the common issues in the currently predominant zero/low-IF receivers, such as poor 2nd-order nonlinearity, sensitivity to 1/f (i.e. flicker) noise and time-variant dc offsets, especially in the fine CMOS technology. To avoid interferers and blockers at the susceptible image frequencies that the high-IF entails, band-pass filters (BPF) with high quality (Q) factor components for sharp transfer-function transition characteristics are now required. In addition, integrated low-pass filters (LPF) with strong rejection of out-of-band frequency components are essential building blocks in a variety of applications, such as telecommunications, video signal processing, anti-aliasing filtering, etc. Attention is drawn toward structures featuring low noise, small area, high in-/out-of-band linearity performance, and low-power consumption. This thesis comprises three main parts. In the first part (Chapters 2 and 3), we focus on the design and implementation of several innovative wideband low-noise (transconductance) amplifiers [LN(T)A] for wireless cellular applications. In the first design, we introduce new approaches to reduce the noise figure of the noise-cancellation LNAs without sacrificing the power consumption budget, which leads to NF of 2 dB without adding extra power consumption. The proposed LNAs also have the capability to be used in current-mode receivers, especially in discrete-time receivers, as in the form of low noise transconductance amplifier (LNTA). In the second design, two different two-fold noise cancellation approaches are proposed, which not only improve the noise performance of the design, but also achieve high linearity (IIP3=+4.25 dBm). The proposed LN(T)As are implemented in TSMC 28-nm LP CMOS technology to prove that they are suitable for applications such as sub-6 GHz 5G receivers. The second objective of this dissertation research is to invent a novel method of band-pass filtering, which leads to achieving very sharp and selective band-pass filtering with high linearity and low input referred (IRN) noise (Chapter 4). This technique improves the noise and linearity performance without adding extra clock phases. Hence, the duty cycle of the clock phases stays constant, despite the sophisticated improvements. Moreover, due to its sharp filtering, it can filter out high blockers of near channels and can increase the receiver’s blocker tolerance. With the same total capacitor size and clock duty cycle as in a 1st-order complex charge-sharing band-pass filter (CS BPF), the proposed design achieves 20 dB better out-of-band filtering compared to the prior-art 1st-order CS BPF and 10 dB better out-of-band filtering compared to the conventional 2nd-order C-CS BPF. Finally, the stop-band rejection of the discrete-time infinite-impulse response (IIR) lowpass filter is improved by applying a novel technique to enhance the anti-aliasing filtering (Chapter 5). The aim is to introduce a 4th-order charge rotating (CR) discrete-time (DT) LPF, which achieves the record of stop-band rejection of 120 dB by using a novel pseudolinear interpolation technique while keeping the sampling frequency and the capacitor values constant.   97
• Publication Frequency Control of Virtual Power Plants ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Zhong, Weilin   ; 0000-0001-6737-4873 The Virtual Power Plant (VPP) concept refers to the aggregation of Distributed Energy Resources (DERs) such as solar and wind power plants, Energy Storage Systems (ESSs), flexible loads, and communication networks, all coordinated to operate as a single generating unit. Using as starting point a comprehensive literature review of the VPP concept and its frequency regulation technologies, the thesis proposes a variety of frequency control and state estimation approaches of VPPs, as follows. First, the thesis studies the impact of coordinated frequency control of VPPs on power system transients, in which ESSs are utilized to provide fast frequency regulation. The thesis also proposes a simple yet effective coordinated control of DERs and ESSs able to integrate the total active power output of the DERs, and, thus, to improve the overall power system dynamic performance. The impact of topology on the primary frequency regulation of VPPs is also investigated. With this regard, two types of VPPs topologies are considered, that is, a topology where the DERs that compose the VPP are scattered all-over the transmission grid; and a topology where the DERs are all connected to the same distribution system that is connected to the rest of the transmission grid through a single bus. Next, the thesis proposes a control scheme to improve the dynamic response of power systems through the automatic regulators of converter-based DERs. In this scheme, both active and reactive power control of DERs are varied to regulate both frequency and voltage, as opposed to current practice where frequency and voltage controllers are decoupled. To properly compare the proposed control with conventional schemes, the thesis also defines a metric that captures the combined effect of frequency/voltage response at any given bus of the network. Finally, the thesis presents an on-line estimation method to track the equivalent, time-varying inertia as well as the fast frequency control droop gain provided by VPPs. The proposed method relies on the estimation of the rate of change of the active and reactive power at the point of connection of the VPP with the rest of the grid. It provides, as a byproduct, an estimation of the VPP’s internal equivalent reactance based on the voltage and reactive power variations at the point of connection. Throughout the thesis, the proposed techniques are duly validated through time domain simulations and Monte Carlo simulations, based on real-world network models that include stochastic processes as well as communication delays.   150
• Publication Low-Complexity Digital Predistortion for 5G Massive MIMO and Handset Transmitters ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Wang, Xiaoyu   The demand for new wireless communication systems to support high mobility and low latency necessitates a rethink of the architecture of wireless communication systems as well as the design of their key components. This thesis presents several novel techniques to solve the major challenges in digital predistortion (DPD) for millimeter wave multi-input multi-output (MIMO) and handset transmitters to lower the hardware cost and computational complexity of the fifth generation (5G) communication systems. The first part of the thesis focuses on the architecture of the MIMO DPD solution for 5G transmitters. To extract DPD model coefficients, a feedback data acquisition path is required. In conventional single-input single-output (SISO) systems, the output is usually acquired directly from the power amplifier (PA) with a coupler. In massive MIMO systems, the number of RF chains is large. Using dedicated feedback paths for each PA separately is not feasible. To lower the hardware cost, a novel data acquisition scheme is proposed to obtain the output signals in far field over the air (OTA) using a single antenna and feedback loop, and then reconstruct the output of each PA. Simulation and experimental results demonstrate that the proposed OTA data acquisition can accurately reconstruct the output of each PA in the MIMO systems and the DPD solutions derived from the reconstructed data can successfully linearize the nonlinear MIMO transmitters. In the multi-user scenario, the nonlinearity of the transmitters varies with the movement of user equipments (UEs), and the DPD model coefficients need to be updated accordingly. To meet the requirement of high mobility, the complexity of the system update must be low. In the second part of the thesis, we present a new DPD system, where DPD model can be updated fast and accurately without capturing PA output or applying costly model extraction algorithms. In the proposed method, nonlinear characteristics of the PA are encoded into low-dimensional PA features using feature extraction algorithms. To identify DPD model coefficients, PA features are extracted first and the DPD model coefficients are then generated directly by DPD generator with PA features. Experimental results show that the proposed DPD solution can linearize PA with very low complexity compared to that using the conventional solutions. Finally, the focus shifts to handset transmitters. Conventionally, DPD is usually deployed for high power base stations. With the continuously increasing bandwidth, DPD may also be required for handset PAs in 5G communication systems. Different from the models used for base stations, DPD model for handset PAs must have very low complexity because of the stringent power budget limit. At the same time, the tolerance for load mismatch must also be considered. The third part of the thesis analyzes the characteristics of handset PAs with load mismatch and introduces a low-complexity DPD model based on magnitude-selective affine (MSA) function. Experimental results demonstrate that the extended MSA (EMSA) model shows better linearization performance while keeping much lower complexity than the conventional DPD models.   9
• Publication Circularly Polarized Antennas for 5G Millimetre-Wave Communications ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Sadeghi-Marasht, Samaneh   The need of a higher data rate, lower latency, and cost efficiency led to the fifth-generation (5G) emerging as a new communication standard. This generation includes many unused frequencies with high available bandwidth channels that can provide higher capacities such as millimeter-wave (mm-wave) bands. One of the main challenges of working at high frequencies of this generation is path loss that needs to be addressed. To overcome this issue, a high gain antenna with a small size is required. Consequently, the first major question arises: how to effectively increase the gain and efficiency of the antenna at a high frequency with a small size. Importantly, it is vital to transport as much as data is possible without any sensitivity to the alignment of the transmitter or receiver antenna that can be satisfied by using circularly polarized (CP) radiating waves. Thus, the second research question emerges: how to provide high gain small size antenna with CP at high frequencies. To address the first two major research questions in this thesis we designed a miniature dual-band CP antenna that works at 28 GHz and 38 GHz with high gain. This antenna can be implemented in mobile devices, unmanned aerial vehicles (UAVs), and base stations (BSs) because of the small sizes of 11 × 14 × 0.508 mm3. For getting a deep insight into the structure and the design procedures of the dual-band antenna, characteristic mode analysis (CMA) is employed. Note that the CMA is not sensitive to the feeding position and the material in this analysis is not lossy. Therefore, after using CMA, the optimization is conducted in the full-wave simulation as the feeding is added to the structure, and the material is lossy. The single CP antenna covered the bands of 27-28.4 GHz and 34.7-40 GHz, with a maximum gain of 6.3 dBiC and 5.51 dBiC at 28 GHz and 38 GHz, respectively, whereas the radiation efficiency is 94% and 96% with the ARBW of 2.5% and 1.5%. A phased antenna array is then constructed to provide a higher gain for this designed dual-band antenna. In a phased antenna array we consider four designed single element antennas close to each other to create a 2 × 2 antenna array with high gain at 28 GHz and 38 GHz. For a 4 × 4 antenna array, an electromagnetic band-gap (EBG) is used to reduce the mutual coupling between elements in the array. The radiating signals will be sent to different users with circular polarization via electronic beamforming. The position of each antenna element is also optimized to provide the constructive radiating wave towards our desired directions. The array was able to steer the beam between -26.5 to 29.5 degrees for the lower band and -29.5 to 35.5 degrees for the higher band with the maximum gain of 12.8 dBiC and 11.5 dBiC, respectively. Another method to enhance the gain is implementing a lens structure in front of the radiating antenna. Here, a significant challenge is to maintain the CP of the incoming CP wave while the gain is increased. Therefore, the third research question is how to design a lens with the capability of enhancing the gain and keeping the CP when the lens is fed by a CP antenna source. Concerning the third major research question, in this thesis, we designed a CP lens structure. First, a multi-layer lens with a thickness of 2.03 mm was designed, and then a one-layer lens structure with a thickness of just 0.508 mm was made. The lens was located in front of different radiating antennas. These lens structures resulted in significant gain enhancement for various feeding antennas working at 28 GHz. The unit cell of the one-layer lens can provide a broad phase shift compared to the multi-layer counterpart. The proposed lens structures not only increased the gain of the incoming CP wave but also kept its polarization to overcome the issues of reflectivity, absorption, inclement weather, and mis   16
• Publication Contributions to the theory and development of low-jitter bang-bang integrated frequency synthesizers ( University College Dublin. School of Electrical and Electronic Engineering, 2022 ) Avallone, Luca   The advent of next-generation wireless standards demands ever-increasing data-rate communication systems. It mainly involves a higher carrier frequency to take advantage of wider bandwidth channels and more complex modulation schemes to pack more information into each symbol. In this context, the bottleneck is represented by the frequency synthesizer used to generate the local oscillator signal for the transceiver, which has to operate under stringent low output jitter requirements. Such performance must be provided at low power dissipation and area consumption in order to meet the requirements of low-cost and high integration level of the modern communication systems. The digital phase locked loop architecture can meet the required jitter performance while synthesizing fractional-N frequencies. Such PLLs offer significant advantages over their traditional analog counterpart in terms of area occupation, flexibility and scalability in advanced deep sub-µm CMOS technologies. The digital PLL topology based on a bang-bang phase detector, denoted bang-bang PLL, which is a single bit digital phase detector, leads to a less complex and more power-efficient architecture, but, on the other hand, it also introduces a hard nonlinearity in the loop, making the analysis of the bang-bang topology more challenging than in the multi-bit case. A comprehensive phase noise analysis of bang-bang digital PLLs is presented which overcomes the limitations of previous models and it is valid in all cases where physical noise sources (i.e. reference and DCO) are dominant with respect to quantization errors. In particular, (i) input-referred jitter is estimated by means of a linear time-domain analysis derived from a nonlinear DPLL model, and (ii) phase noise spectra are predicted using a discrete-time domain model that accounts for time-variant effects that arise from the intrinsic multirate nature of the DPLL. The possibility of accurately determining the DPLL jitter and phase noise spectra, enabled by the novel analysis presented in this thesis, is key to significantly speeding up the design-space exploration phase, since it allows one to perform quick and precise parametric sweeps. However, even when designed properly, bang-bang PLLs are affected by the unavoidable bang-bang phase detector quantization noise, which is added on top of the intrinsic reference and DCO phase noise. The quantization noise can be appreciated in the PLL's output spectrum as increased in band noise with respect to the analog counterpart, that, in fact, still achieves superior performance in terms of jitter-power. This results in worse integrated jitter performance for the same intrinsic levels of reference and oscillator phase noise. To overcome the binary phase detector quantization noise in DPLLs, state-of-the-art works rely on a multi-bit time-to-digital converter to digitize the PLL phase error with a physical resolution below the input jitter, leading to increased design complexity, with an associated area and power penalty. In order to overcome the ultimate limit of the bang-bang PLL, a digital PLL based on a bang-bang phase detector with adaptively optimized noise shaping has been fabricated in a 28nm CMOS process. The prototype occupies a core area of 0.21 mm2 and draws 10.8 mW power from a 0.9 V supply. The integrated jitter is 69.52 fs and 80.72 fs for the integer-N and the fractional-N case, respectively. Achieving a jitter-power figure-of-merit of -251.5 dB in fractional-N mode, the proposed system effectively bridges the gap to analog implementations. The first chapter of this work is introductory, and is intended to give some background information needed to underpin the remaining part of the thesis. The following chapters, 2, 3 and 4, collect the results achieved during the PhD activity, and each of them is associated with a publication. In the last chapter, conclusions are drawn and the open points are discussed in order to be considered for future work.   223

TELECOMMUNICATION THESIS IDEAS/TOPICS

Telecommunications refers to the electrical transfer of data throughout long ranges. Voice telephone conversations, information, texts, photos, or multimedia would all be used to communicate messages. Telecommunications are being utilized to connect distant systems to form network infrastructure.

This article is a complete picture of various telecommunication thesis ideas and methods of doing successful research in them.

Let us first start with the basics of Telecommunication.

What is T elecommunication and examples?

Telecommunication is the use of electromagnetic waves or radio signals to communicate over long distances

• The telephone system
• Radio broadcasting systems
• Computer systems

These are all examples of telecommunications systems. Our technical experts have worked with top researchers of the world and so we have gained a lot of expertise in telecommunication projects . You shall talk to our research experts for a more detailed explanation of any aspects of Telecommunication networks . Let us now look into the structure of Telecommunication networks

Telecommunication Network Structure 

Each telecommunications network, generally, is divided into three components, (or planes) and are considered as independent overlay networks

• It is the career of real payload or user traffic in the network 
• It is also called bearer plane, user plane, and forwarding plane
• Data related to network controls are carried by this plane
• This process is also called signaling
• Administration related operations and management of traffic is performed using this plane
• At times it is also considered to be an inherent aspect of control plane

Once you reach out to us we will provide you with an ample amount of research data and information from authentic research materials to give you an overall understanding of the different components involved in the architecture of Telecommunication networks as mentioned above. Now let us talk about the purposes of establishing telecommunication networks. 

What are the Objectives of Telecommunication Networks?

• Maximization of allocating bandwidth and power
• Fair allocation of resources and load balancing
• Reducing congestion and enhancing fault tolerance
• Ensuring network security

Apart from these general objectives, we have also worked on specific research objectives and have delivered successful telecommunication projects . We also stand with our customers in the real-time implementation and help them in making analyses for further improvement with telecommunication thesis ideas. Let us know to see the conventional protocols used in telecommunication networking .

Traditional Telecommunication Protocols

• The word protocol is often used in telecommunications to refer to a collection of laws and restrictions that regulate the aspect of digital data exchange among entities located at various distances
• Furthermore, because telecommunication encompasses a wide range of technological developments, several protocols are used to facilitate flow of information in various sectors of electronic communication. 

The following are the most important protocols used in telecommunication network projects

• Base station management application part (or BSMAP), base station subsystem application part (or BSSAP) and base station subsystem management application part (or BSSMAP)
• Base transceiver station management (or BTSM) and short message service transfer layer protocol (or SMSTP)
• Mobile application part (or MAP) and direct transfer application part (or DTAP)
• Stream control transmission protocol (or SCTP) and signalling system 7 (or SS7)
• Integrated Services Digital Network (or ISDN) protocols
• V5.1 and V5.2 protocols
• Session Initiation Protocol (or SIP) and Media Gateway Control Protocol (or GCP) 
• Session Announcement Protocol (or SAP), Signalling Gateway Control Protocol (or SGCP) and Session Description Protocol (or SDP)
• Multipurpose Internet Mail Extension (or MIME) and H.248 and H.323
• Internet Protocol (or IP), Hyper-text Transfer Protocol (or HTTP) and Simple mail transfer Protocol (or SMTP)
• Transmission Control Protocol (or TCP), File Transport Protocol (or FTP) and Post Office Protocol (or POP)
• Reservation Control Protocol (or RSVP), Unified Datagram Protocol (or UDP) and Dynamic Host Control Protocol (or DHCP)
• Real Time Protocol (or RTP) and Border Gateway Protocol (or BGP)

Usually, we provide total technical assistance which covers the writing algorithms and handling all standard protocols . So you shall feel free to contact us for solving any kind of technical queries regarding these protocols. The following is a comparison of UDP and TCP transport protocols .

UDP and TCP transport protocols comparison

• Packet loss is not detected and delivery is out of order and is also not guaranteed
• Jitter and delay are minimized
• It can be implemented in real time applications
• Connection cost  and packet header overhead are 28 bytes and 8 bytes respectively 
• Idle session timeout is 5 minutes
• Faster data transmission and live streaming are supported
• They are used in association with TFTP, DHCP, VoIP, SNMP, DNS and RIP
• Packet losses can be detected
• It provides for byte – oriented flow and reliable packet delivery (in – order)
• Congestion control, Jitter and delay in retransmissions 
• Difficulty in real time deployments
• Correction of errors and redundancy are supported
• Packet header overhead and connection cost are 20 bytes and 300 bytes respectively
• 60 minutes is the idle session out timing
• It is generally deployed in SMTP, FTP and HTTP 

Both of these protocols are packet-based approaches. These are the best efforts for connectionless or wireless establishments . You shall get complete guidance regarding the practical applications of these protocols from us. Now let us look into the important applications of Telecommunication networks

• Architecture of computer networks (system of communication that allows for data transmission among various computer components)
• Permits additional data requests for tedious tasks (difficult to resolve)

We will provide you advanced research data to give you a great understanding of different aspects of Telecommunication networks . Research scholars and final year students actively approach us by considering our successful projects that were delivered and ongoing. In this regard, we are able to provide you the various quality of service parameters used in assessing different telecommunication projects .

Quality of Service (QoS) for Telecommunication Networks

• Quality of service (QoS) factors are those combination of a telecommunication platform’s features that influence its capacity to meet the expressed and implicit expectations of its stakeholders
• Due to highly dynamic route allocations, energy efficiency, and fault – tolerant measures deployed, achieving QoS is often difficult
• As a result, multiple QoS categories could be evaluated in order to synchronize the network structure and protocols deployed for specific purposes
• In ad-hoc communications via refining routing decisions
• In cellular systems via mobility Predictions and call admission control (or CAC) 

The following are the important quality of service parameters that can be used in telecommunication network analysis

• Time of transmission and link throughput
• Packet delivery ratio and average end to end delay
• Total throughput of the network

All our projects have shown excellent results when accessed based on these parameters. Let us now look into the quality of experience parameters involved in telecommunication network performance analysis .

QoE Metrics for telecommunication networks

QoE is the general acceptance of a program or service, as judged by the end-users.  The Quality of Experience (QoE) is a method for measuring and reporting the users’ experience and perceptions of services, usually as quantitative data.

• The QoE on the other hand, is more than an indication because it investigates the degree of confidence and responsiveness to the services. While contemplating how to construct the entire network of telecommunication services, it is an essential factor to address
• The QoE metrics can be linked to qualitative and quantitative performance standards
• So they extend beyond augmenting the practical performance measures provided by the QoS metrics
• As 5G systems change from network-centric mode to human-centric design, network monitoring evolves from QoS to QoE performance assessment

So understanding all the QoE metrics used in telecommunication networks plays an important role in assessing the performance of your project. Therefore, let us now talk about the Peak signal-to-noise ratio which is among the most often utilized QoE quantifiable measurements (PSNR)

• As video streaming services tend to rise congestion in upcoming broadband services, it could be used to assess the quality of service delivery and also to identify any defects
• The PSNR is indeed the basic FR kind of the QoE measure
• It is basically an inverted measurement of the mean square error (MSE)
• Yet, because the PSNR measurement is already demonstrated to be incompatible with human vision, additional complicated FR measurements including as the structural similarity index (or SSIM) and perceptual evaluation of video quality have been established (or PEVQ)

Let us now look into some of the other important subjective metrics used in this regard for the evaluation of data transmission in telecommunication networks

• Used in measuring the quality of video
• It is little sensitive to the context
• It may not be efficient for deployment in real-time assessments
• This is used in applications like video streaming, television, multimedia and picture quality
• This metric is a combination of several factors related to network vulnerabilities which include delays and packet losses
• It is better suited for applications like real time monitoring, video streaming, RR and NR approaches and IPTV
• It evaluate the information degradation like contrast and luminance
• So it is used in assessing the quality of videos, images and FR methods
• It is involved in real time quality assessment of communication using packets
• Audio and video quality are assessed using this parameter
• The artefacts as a result of human activities which include the gallery distortions, blocks and codec types are measured using this metric
• It is used in applications like FR methods and video quality assessment
• Vulnerabilities in both time and space are considered by this metric
• It involves higher cost of computation and memory
• It is used in applications related to FR methods
• As we have seen before it finds the similarity among various images by utilising mean squared error
• Though perception of users are not considered it becomes the better metric for simple assessment of video quality

A Ventilation Coach for Opioid Overdose Bystanders Takes Top Prize at Inaugural Capstone Design Expo

• student competition
• undergraduate
• capstone design expo

Dean's Award winners with Testudo, Dean Samuel Graham, Jr., and Fischell Department of Bioengineering Chair John Fisher

The opioid overdose epidemic—which claimed more than 110,000 lives in the U.S. last year alone—has prompted an urgent need for accessible solutions to save lives outside of hospital settings.

Maryland bioengineering seniors rose to the challenge in the Clark School’s inaugural Capstone Design Expo by developing a device that empowers bystanders and non-EMTs to properly and safely provide overdose victims with rescue breaths.

Their capstone design project, “ Accessible Ventilation Coach for Opioid Overdose Bystanders ,” won the Dean’s Award (and a $1,000 prize) at the May 1 event, held on UMD’s College Park campus at the XFINITY Center. The bioengineering team’s innovative adjunctive device, which uses a printed circuit board, connects to a bag valve mask (BVM) and provides visual guide LEDs for the proper rate and depth of breath compressions, along with feedback LEDs synchronized with the user’s performance. An audio system also provides coaching during use, guiding users in real time to increase or decrease their speed or pressure of compressions. Advisors to the team were Associate Professor Ian White of the Fischell Department of Bioengineering and Robert E. Fischell Institute for Biomedical Devices , and physician scientist, entrepreneur, and Associate Dean for Innovation and Physician Science Development at the University of Maryland School of Medicine, Dr. Jason Rose.

“The number one cause of death from opioids is respiratory failure,” explained team lead and Clark School senior Kelly Yeung, “so the best immediate treatment is to support respirations. But safe use of a BVM requires training: That’s why we developed this device, to empower people to perform life-saving breaths before EMS arrives,” said Yeung, who also works as an additive technician at Terrapin Works . “We’ve imagined that this could be similar to an automated external defibrillator for cardiac arrest—and stationed in similar locations.”

The Capstone Design Expo brought more than 500 senior-level students from across Maryland Engineering’s civil and environmental, aerospace, mechanical, and bioengineering programs to present their capstone projects. Working under the guidance of faculty members and industry experts, students engaged in a year-long engineering project process that culminated in the design competition judged by experts in their respective fields.

“I want to thank our students for designing these innovative engineering solutions to some of the grand challenges we’re facing. We are very proud. These projects point to your quality work and collaboration—and to your desire to make a difference in the world through engineering,” Clark School Dean Samuel Graham, Jr., told the participants at the event.

Capstone Design Expo Photo Gallery Recap Video

Civil and environmental engineering senior projects ranged from heat index and power outage emergency frameworks, to analysis of roadway infrastructure, to “cooler” solutions for bus stop design in Washington, D.C. Working under the guidance of Professor Deb Niemeier , the Clark Distinguished Chair in Energy and Sustainability, with senior project manager at Allan Myers Will Sigafoose as client contact, the department’s winning project, “ Alternative Central Avenue Conduit System ,” provides a case study in response to the Central Avenue Design-Build project in Baltimore and serves as a general guide for future conduit redevelopment projects.

“The students are eager to show what they’ve accomplished, not only solving engineering problems but helping to solve ethical and social issues, too,” said Nii O. Attoh-Okine , chair of the Department of Civil and Environmental Engineering. “It’s not all about profit, but it’s about answering the question, ‘how did we touch others with our design’?”

Bioengineering and biocomputational engineering majors worked to make medicine safer, more effective, and more accessible through projects that aim to improve current standards of care for treating aneurysms, diagnosing Covid-19, improving the tracheostomy process, and more. The winning team’s project, “ A Modified Syringe Design to Simplify the Preparation of Weight-Based Pediatric Medication ,” proposes a cost-effective, user-friendly, syringe-like device that features an adjustment dial to reduce risk of error and improve pediatric patient outcomes.

Project judge Matthew Dowling ’12 is founder and chief scientific officer of biotechnology research company Medcura and a member of the department’s advisory board. Having participated in departmental capstone showcases for several years, he said he always enjoys the interaction with students. “I get to hear how they’re learning about bioengineering and applying what they learn,” he said. “It’s great how they’re partnered with clinicians who introduce them to real, unmet needs—that’s huge.”

Alison Flatau , chair of the Department of Aerospace Engineering, called the Capstone Design Expo “a fantastic opportunity for students and faculty.” She said she was impressed with how well teams of more than twenty students tasked with mission challenges were able to integrate their pieces of the larger, system-level scope. “It gave me a great sense of pride seeing how well prepared our students are for taking on the big and high-impact challenges that are ahead of them.”

Project judge Megan Bock ’06, M.Eng. ’10 , a missions systems engineer at NASA Goddard Space Flight Center, remembers her own capstone process as a Clark School student. “I know what the capstone experience did for me. I learned a ton, and it was probably the most realistic simulation of life as a NASA engineer,” she said. That’s why she returns to campus: “I view this as part of the cycle of life, and I want to come back and see who I’m going to be working with someday.”

Harry Dankowicz , chair of the Department of Mechanical Engineering, noted the enormous diversity—and coverages—he saw at Capstone Design Expo. “Even in different engineering disciplines, our students are often tasked with the same kinds of challenges, and they have to bring in tools from outside of what they’re immediately learning,” he said. “There’s both the diversification of the problems and the convergences that really make a difference to solutions.”

As executive vice president and chief operating officer at the Housing Authority of Baltimore City, mechanical engineering alumna and project judge Monica Watkins ’94 is always on the lookout for tomorrow’s engineers. “I have made it my personal mission to be involved,” she said, and she liked what she saw. “What I’m observing is the thought process—the intentionality, the critical thinking, the strategic planning and design. We value those skills. Not just that you’re an engineer, but that you have the mindset to work through problems and recommend solutions that we may not have considered.”

For the Dean’s Award winners, the team is looking ahead to what’s next for their medical device to empower opioid overdose bystanders. “I was super stoked to hear from everyone that they wanted to see this go to market and that they see this as a viable solution,” said Yeung. “Moving forward I want to see where this goes. I think it could be something big.”

The MIT Bike Lab: A place for community, hands-on learning

Press contact :.

Bianca Champenois SM ’22 learned to ride a bike when she was 5 years old. She can still hear her sister yelling “equal elbows!” as she pushed her off into the street. Although she started young, her love of bikes really materialized when she was in college.

Champenois studied mechanical engineering (MechE) at the University of California at Berkeley, but with a first-year schedule comprising mostly prerequisites, she found herself wanting more hands-on opportunities. She stumbled upon BicyCal, the university’s bike cooperative.

“I loved the club because it was a space where learning was encouraged, mistakes were forgiven, and vibes were excellent,” explains Champenois. “I loved how every single bike that came into the shop was slightly different, which meant that no two problems were the same.”

Through the co-op’s hands-on learning experience, the few long rides she took across some of California’s bridges like the Golden Gate, and the lively evening “Bike Parties” drafting behind friends, Champenois’s love for biking continued to grow. When she arrived at MIT for her master’s studies, she joined the cycling team.

Champenois, who is also passionate about climate action, enjoyed the sense of community the cycling team offered, but was looking for something that also allowed her to solve problems and work on bikes again.

After discovering there wasn’t a comparable cooperative bike program at the Institute, Champenois was determined to start one herself. It wasn’t long before she secured club funding from The Coop’s Public Service Grant with the support of her peer, Haley Higginbotham ’21, who was also passionate about the cause. By the end of the year, the team had gained two more volunteers, civil and environmental engineering graduate student Matthew Goss and materials science and engineering grad student Gavin Winter, and the MIT Bike Lab was born.

"The idea is to empower people to learn how to fix their own bike so that they are motivated to use biking as a reliable transportation method," says Champenois. The volunteer mechanic has a vested interest in promoting sustainability and improving urban infrastructure.

Champenois is a graduate student in the joint Mechanical Engineering and Computational Science/Engineering program, and her research involves applying data science and machine learning to fluid dynamics, with a specific focus on ocean and climate modeling. The NSF Graduate Research Fellow is now building upon prior research focused on ocean acidification as part of her PhD thesis, while she is also involved in other projects within Professor Themis Sapsis’s Stochastic Analysis and Nonlinear Dynamics (SAND) Lab .

“I appreciate that my research strikes a balance between more applied environmental projects and more theoretical statistics and computational science,” she explains while referencing a recent research contribution to a project focused on improving global climate simulations.

Champenois’s academic research focus may be specific, but she stresses that the Bike Lab isn’t targeted to any particular interest and welcomes all who are eager to learn.

“If you're interested in solid mechanics, you can think about bike frames. If you're interested in material science, you can think about brake pads. If you're interested in fluids, you can think about hydraulic brakes,” she says. “I think there's something for everyone, and there's always something to learn.”                            

In the last year-and-a-half, the Bike Lab is estimated to have serviced over 150 bikes, and they’re only getting started. Champenois is ambitious about the Bike Lab’s future.

“I hope to teach classes, maybe throughout the semester or as a standalone IAP [Independent Activities Period] course. I am also really interested in the idea of managing a vending machine for parts,” states Champenois.

In the winter, the Bike Lab stores its tools in N52-318, but the club lacks the space needed to expand. “Without our own space, it is difficult for us to store parts, which means that people are required to bring their own parts if their repair requires a replacement,” explains Champenois.

While physical space isn’t required to build a sense of community, Champenois envisions the Bike Lab exuding the same sort of camaraderie as the Banana Lounge , another of one MIT’s student-run spaces, one day.

“I like to think of the Bike Lab as more than just a bike shop. It's also a place for community,” she says.

Champenois hopes to complete her degree in the next year or two and would like to become a professor someday. She is excited by a career in academia, but she says she could also see herself working on a climate or weather research team or joining an ocean technology startup.

Many have heard the expression that being a student at MIT is like “drinking from a firehose,” but that is one of the things Champenois will miss most when she leaves.

“I have had the opportunity to discover so many new hobbies and been able to learn so much through sponsored activities,” she recalls. “Most importantly, I'll miss the great people I have met. Everyone at MIT is so curious and hardworking in a way that is truly energizing.”
