Architectural Innovations for Efficient Denoising and Classification: A Manual vs. Neural Architecture Search Comparison

In this paper, we combine image denoising and classification, aiming to enhance human perception of noisy images captured by edge devices, like security cameras. Since edge devices have little computational power, we also optimize for efficiency by proposing a novel architecture that integrates the two tasks. Additionally, we alter a Neural...

Cross-layer Optimization of MAC Scheduling for Multi-User Virtual Reality over 5G

As a result of a global pandemic, there has been an increasing interest in tools for remote video conferencing and collaboration. One of these new innovations is social eXtended Reality (XR). By combining Virtual Reality (VR) and Augmented Reality (AR) technologies, social XR can provide a more immersive experience than any other VR application...

The negative latency haptic glove: Making Tactile Internet tangible

The field of Tactile Internet (TI) is transporting physical interactions over vast distances as if they were near. This teleoperation method increases the quality of tele-engineering, telesurgery and many other fields. However, it requires the strict end to end latency constraints of a few ms, which is still out of reach. This thesis looks at...

S-Query: Opening the Black Box of Internal Stream Processor State

At the moment we are witnessing the maturation of distributed streaming dataflow systems whose use-cases have departed from the mere analysis of streaming windows and complex-event processing, as they now extend to cloud applications, workflows and even e-commerce. The state of streaming operators has been so far hidden from external...

High throughput data interfacing: for real-time medical imaging applications

Current high-end medical X-ray intervention devices provide a tremendous amount of high-definition images per second. Combined with the additional inputs from the numerous auxiliary devices, processing and compositing the data in real-time quickly becomes an arduous engineering challenge. Furthermore, the critical nature of this application...

Tracking Electromechanical Muscle Dynamics using Ultrafast Ultrasound and High-density EMG

Muscles generate force and enable movement. After excitation of a muscle the muscle fibers contract. Methods to assess muscle contraction in vivo are scarce. Electromechanical delay (EMD), defined as the time lag between muscle excitation and contraction onset, has been proposed as a measure for contraction efficiency, but provides limited...

The use of interactive media applications is becoming more common. With the current advancements in technologies, applications are becoming more advanced and research is being performed into adding more modalities to these applications to enrich the experience and increase their capabilities and uses.<br/> he performance of these applications...

Exploring Gravitational Waves Recordings with Machine Learning Techniques

The study of Gravitational Waves (GWs) opened a new window of possibilities to improve our understanding of the Universe. GWs provide suitable astronomical messengers for studying events that were not possible before through electromagnetic radiation, or in other cases complementing their observations. Ground-based interferometers like LIGO have...

Communicating with low latency peers: Building a low latency overlay in P2P networks

In decentralized applications requirements on latency are high. For instance, in trading<br/>applications a millisecond latency advantage can save companies millions of dollars. In<br/>this thesis a design is proposed for an overlay in a decentralized peer-to-peer system<br/>that lowers the latency between connected peers. The overlay is...

Latency Analysis and Reduction in a 4G Network

5G, the next generation of mobile network, is expected to be launched commercially around 2020. Compared to the present generation – 4G mobile network, a significant improvement in terms of performance and reliability is considered for 5G. One of the important factor in the design of 5G is – about 10 times lower packet latency than 4G. Some of...

Feeding High-Bandwidth Streaming-Based FPGA Accelerators

A new class of accelerator interfaces has signi cant implications on system architecture. An order of magnitude more bandwidth forces us to reconsider FPGA design. OpenCAPI is a new interconnect standard that enables attaching FPGAs coherently to a high-bandwidth, low- latency interface. Keeping up with this bandwidth poses new challenges for...

Improving video game experience by reducing latency

The Dutch internet service provider KPN focusses on offering high quality products to the market and facilitating their users in the best way possible. In the perception of the consumer they are, however, unable to deliver this high standard on the facilitation of online video games. It is expected that this is caused by a relatively high...

Cache Balancer: A communication latency and utilization aware resource manager

The increasing number of processors in today's many-core architectures has lead to new issues regarding memory management. The performance of many-core processors is often limited by the communication latency incurred in data transfers between different cores. Conventional memory allocators do not take such communication costs into account while...

Anonymous HD video streaming

No scalable privacy-enhancing technologies exists that is capable of anonymous HD video streaming. Our paper discusses the new anonymizer built into Tribler, a social content-sharing client. With anonymous HD-video streaming as the main objective requirements as at least 10 Mbit/s throughput, user bandwidth donations and NAT-traversal are...

Finite Abstractions of Network Calculus Elements for Formal Verification of Network Bounds

This thesis presents a method to semi-automate the reasoning about network bounds, namely the backlog and delay. Network Calculus offers a rich theory for modeling network elements. Using the modeling techniques of network calculus, network elements are represented by discrete-time systems whose dynamics are linear in min-plus algebra. From the...

Performance estimation technique for optimizing and integrating IPs in MPSoCs

Over the last decade, the complexity of system-on-chips (SoCs) has continuously increased owing to the increasing demand for high performance IPs and SoCs. However, the productivity of chip designers has not scaled up at the same rate. This has led to an enormous design productivity gap. At the same time, the increasing time-to-market pressure...
