Research Seminar 29th May, Mr. S.M. Rahimi A. – Programmable Spike-Timing Dependent Plasticity learning circuits in neuromorphic VLSI architectures

    Abstract: Hardware implementations of spiking neural networks offer promising solutions for computational tasks that require compact and low power computing technologies. As these solutions depend on both the specific network architecture and the type of learning algorithm used, it is important to develop spiking neural network devices that offer the possibility to reconfigure […]

Research Seminar 15th May, Mr S. Keen – Interpretation and Grouping of Motion Using an AI (Soar) as a Perceptual Hierarchy

  Abstract: In many high level cognitive systems used in AI, such as Soar, visual and recognition processes are typically implemented as hard coded subsystems approximating cognitive sub-processes. This poses the question of how a high level cognitive architecture, such as Soar, can be used to perform lower level cognitive processing such as perceptual grouping […]

Research Seminar 8th May, Mr P. Fisher – Cost Effective Radio Frequency Power Amplifier Linearization Techniques

  Abstract: In today’s wireless world, RF amplifiers are required to amplify multiple channels with advanced modulation schemes while causing the minimum possible interference to other RF users, as well as being power efficient.  As there is a trade-off between power efficiency and linearity, simple back-off schemes cannot be used as linearization techniques, as this […]

Research Seminar 6th May, Dr Y. Zhu – Towards a GPS Single-Chip smart Antenna System for Interference Mitigation

    Abstract:  This brief demonstrates the feasibility of developing a single-chip GPS anti-jam system for civilian applications. The system dynamic range criterion is analyzed, targeting for a moderate 50 dB anti-jam ratio. Circuit level design of major building blocks using a 0.35um SiGe process is presented with special focus on high linearity achievement such […]

Research Seminar 23rd April – Massive MIMO versus mm-Wave arrays

    Abstract: Massive multiple-input multiple-output (MIMO) has been considered as a key approach for next generation cellular systems to increase the spectral efficiency and improve the energy efficiency. In addition, millimeter wave (mm-Wave) arrays are studied for 5G systems that are based on mm-Wave where a much wider bandwidth is available. Since beamforming plays […]

Research Seminar 24th April – To feel or not to feel; that is the question

  Abstract: Brain-computer interfaces (BCI) have been used to enhance recovery after stroke. Different combinations of feedback modalities have been exploited in the application of BCI for stroke rehabilitation. Most studies have used visual only or a combination of visual and proprioceptive feedback. In this study we compare the performance of 10 healthy subjects on […]

Research Seminar 1st May, Ms N. Shahabi – Global Sensitivity and Uncertainty Analysis of Transients in the Universal Line Model

  Abstract: One of the main aspects of designing and operation prediction of any power system is to simulate its Electromagnetic Transient’s (EMT) performance. Among the available power line models, Universal Line Model (ULM) is an efficient and accurate model for this purpose.  There are random system parameters which affect the quantities of EMT output […]

Research Seminar 10th April – Three Is The Magic Number

  Abstract: The wireless user is driving demand for quality and content. To keep pace, design must head to higher frequencies. Designs at high frequencies offer high capacity that may be compromised by propagation loss restricting the design to reduced coverage. This introduces alignment issues and a possible severe reduction in performance. The alternative is […]

Research Seminar 17th April – A Parallel Implementation of Cue-Based Retrieval for Episodic Memory

  Abstract: Episodic memory has been shown to improve the range of demonstrable cognitive capabilities in intelligent agents. However, current implementations result in an inability to maintain real time performance for agents existing for long time scales. The Soar cognitive architecture automatically encodes agent state at each decision cycle and installs this state in the […]
