Prof. Dr.-Ing. Carsten Markgraf, Parameter Optimization by doing Automated Tests with Formula Student Electric (FSE) Racing Cars , 27th August 2015.
Abstract: For FSE events students build an electric, single seat formula race car with which they can compete against teams from all over the world. The competition is not won solely by the team with the fastest car, but rather by the team with the best overall package of construction, performance, and financial and sales […]
N. Nguyen-Trong, Design and Analysis of a Reconfigurable Antenna Based on Half-Mode Substrate-Integrated Cavity, 11th June, 2015.
Abstract: In the last decade increasing attention and efforts have been placed on designing reconfigurable antennas, especially those utilising substrate-integrated technology which provides many advantages such as low-loss, low cost and ease of circuit integration. This seminar introduces a new type of reconfigurable antenna based on a substrate-integrated cavity with very wide frequency tuning […]
Abstract: A resonant element consisting of three parallel elliptical dipoles is proposed for the design of a broadband reﬂectarray at 1 THz. The phase response of the proposed radiating element is reasonably linear and its gradient is constant over a wide frequency range. A subarray composed of 4 radiating elements with a progressive phase […]
V. Duk – The Potential of 2D Wavelet Transforms for Target Detection in Sea-clutter – 30th April, 2015.
Abstract: In maritime radar target detection, a good statistical representation of the backscatter is important to both minimise false detections and maximise the probability of detection. However, the radar backscatter may contain sea-spikes which can last for seconds and cause false detections. One potential solution to this problem is through the use of time-frequency […]
Research Seminar, Assoc. Prof. M. McDonnell — Enhanced Image Classification With a Fast-Learning Shallow Convolutional Neural Network
Abstract: “Deep learning” methods, such as deep convolutional networks, have inspired a renaissance in neural network use, and are becoming the default option for difficult problems like image and speech recognition. However, here we show that state-of-the-art results for some well-known image classification benchmarks can be surpassed using a “shallow” convolutional neural network. The […]
Research Seminar, Ms X. (Demi) Gao – Modeling electrode place discrimination in cochlear implant stimulation
Abstract: Cochlear implants provide functional hearing to people who are profoundly deaf or hearing impaired by replacing the function of missing sensory receptor cells with an array of stimulating electrodes. We have developed a model for predicting the optimal number of electrodes, as well as the optimal locations and usage probabilities of electrodes, from […]
Research Seminar, Mr H. Yu – Formation Control of Large-Scale Systems and Systems with Arbitrary Formations
Abstract: Flocking and formation control concern the interaction and collaboration of multiple autonomous vehicles. Large-scale systems have been possible due to the emerging of advanced sensors and fast computing units. Researchers have paid growing interests in such systems in the past decade. Application examples include robotics, UAVs, and exploration through unknown environments. In our […]
Abstract: Surface plasmon polaritons (SPPs) are surface electromagnetic waves bound tightly to metal-dielectric interface at optical frequencies. Research on SPP is an important branch of nanophotonics and has promising applications in imaging, sensing, field enhancement, and integrated optics. One important component for manipulating SPPs is a group of plasmonics launchers that couple free-space waves […]
Research Seminar 6th November, Mr. P. Wang – Realizing long-term memory in cognitive architectures using memristors
Abstract: Complex cognitive agents are expected to persist for a long time and acquire a large amount of knowledge in long-term memory. With this large capacity long-term memory, an agent’s real-time reactivity becomes an issue. This research considers designing long-term memory in cognitive architectures using an emerging non-volatile device – memristor. Based on characteristics […]
Research Seminar 23rd October, Mr. C. Zhao – Approximation Methods for Cylindrical Posts in Rectangular Waveguides with Mode Matching Technique
Abstract: Waveguide band-pass filters are essential components in millimeter-wave systems and in order to design such filters, many types of discontinuities, such as irises or E-plane metal inserts, are utilized in rectangular waveguides. Among these usual discontinuities, from a fabrication point of view, cylindrical posts placed in waveguides are more attractive. In this seminar, […]
