OBSERVER BASED ACTIVE DAMPING OF LCL RESONANCE IN GRID CONNECTED VOLTAGE SOURCE CONVERTERS
(2013-05-19)Voltage source converters (VSC) with LCL filters are attractive in grid connected power electronics because they greatly reduce pollution of the utility voltage due to switching harmonics. However, the presence of the LCL ... -
One-shot Unsupervised Learning for Improved Human-Robot Collaboration
(2017-05-16)As robots become commonplace in human environments such as households and manufacturing facilities, they require new control methods for e↵ectively collaborating with their human partners in common pick-and-place tasks, ... -
Optical emission study of ion composition in an inductively coupled oxygen plasma
(2015-08-21)The success of ion implantation to precisely modify substrate properties is dependent on controlling the incident ion energies to achieve the desired depth of the implanted ions. Oxygen plasmas generally contain both O+ ... -
Optimal Proxy-Limited Lines for Representing Voltage Constraints in a DC Optimal Powerflow
(2009-12-15)With the recent restructuring of the electric industry away from the vertically integrated monopolies, electricity markets have emerged in various parts of the country. Independent System Operators (ISOs) and Regional ... -
Optimizing Hierarchical Algorithms for GPGPUs
(2010-05-15)The performance potential of future architectures, thanks to Moores Law, grows linearly with the number of available devices per integrated circuit. Whether these future devices are ultra-small CMOS transistors, nano-tubes, ... -
A Parallel Algorithm for Multi-view Image Denoising
(2014-05-18)In this paper, we propose to improve the denoising performance by exploiting the redundancy provided by the multiple views. Here, we review the rich literature on image denoising methods. Zhang et. al. in [1] conjecture ... -
PARTICLE FILTERING METHOD FOR OBJECT TRACKING AND SENSOR
(2012-05-20)Generally, there is no analytic solution to object tracking problems in non-linear non-Gaussian scenarios, which is a common type of problem nowadays. A particle filter is a numerical method that can be applied to any ... -
pd-gem5: Simulation Infrastructure for Parallel/Distributed Computer Systems for Network-Driven Optimization
(2015-08-21)In developing and optimizing a parallel/distributed computer system, it is critical to study the impact of the com-plex interplay amongst processor, node, and network architectures on performance and power efficiency in ... -
Performance Evaluation of a DySER FPGA Prototype
(2014-08-25)Specialization and accelerators are being proposed as an effective way to address the slowdown of Dennard scaling. DySER is one such accelerator, which dynamically synthesizes large compound functional units to match program ... -
Performance/cost analysis of Software Implemented Hardware Fault Tolerance Techniques
(2010-05-15)As Moore's law projections continue to hold true, more and more transistors are getting integrated on a single chip. These transistors are being smaller each passing technology generation. Forecasts suggest that the ... -
Polarization Modulation for Application in Terahertz Sensing
(2011-05-15)Providing defense against asymmetric threats under many di erent environmental conditions requires broad spectrum sensing and presently underutilized polarization sensitivity. In this thesis a novel pulsed radar sensing ... -
POWER SYSTEM MODELS FORMULATED AS EIGENVALUE PROBLEMS AND PROPERTIES OF THEIR SOLUTIONS
(2010-12-15)Eigenvalue problems incorporate multiplicative nonlinearities in otherwise linear equations. Two power systems models with multiplicative nonlinearities are reformulated as eigenvalue problems. Reformulation allows for ... -
A Practical Energy Reduction Technique Exploiting Synchronization Cycles for Multi-core Processors
(2013-05-19)Spinning had been the classical way of implementing synchronization primitives (i.e., barriers, locks and conditions) in pthread library before the recent adoption of fast user space mutex (futex). While improving energy ... -
PV Balancer --Concept, Architectures and Realization
(2012-05-20)This thesis presents a new concept of module-integrated converters called PV balancers for photovoltaic applications. The proposed concept enables independent maximum power point tracking (MPPT) for each panel, and ... -
