Minimum-Time Motion Planning and Control for Multiple-Vehicles

  Abstract:   Motion planning and control algorithms for multiple nonholonomic vehicle systems are presented. The main problem to tackle is twofold: minimizing the travelling time of the slowest vehicle and designing a tracking controller for each vehicle such that the use of collision avoidance motions can be...

Minimizing Data Movements in Data-Intensive Computing

Data movements, when not carefully optimized, can easily dominate the execution time and energy consumption of running data-intensive applications. This is particularly true with modern computing systems with increasingly high degree of concurrency. Therefore, software that minimizes the data movements will play a key role...

Multimodal image/motion analysis for moving organs

Abstract: Multimodal 3D/4D image/motion analysis for moving organs such as heart and tongue during the speech play an important role to provide a set of objective parameters to interpret quantitatively the motion and establish quantified comparisons. In this talk, I will present two recent and novel...

Beyond the Hill of Multicores lies the Valley of Accelerators

The power wall has resulted in a sharp turn in processor designs, and they irrevocably went multi-?core. Multi-?cores are good because they promise higher potential throughput (and never mind the actual performance of your applications). This is because the cores can be made simpler and...

Motion and spatial regularization designs in motion-compensated image reconstruction

  Medical imaging has been an effective tool for diagnosing diseases including cancer and coronary artery disease, but there are still challenges such as reducing motion artifacts, minimizing toxic radiation dose, and reducing scanning time. These challenges reduce the SNR of the measurements. Model-based image reconstruction...

Cyber Physical Systems : A New Science for Convergence

Recently, the convergence of cyber and physical spaces has transformed traditional embedded systems into cyber physical systems (CPS), which are characterized by tight integration and coordination among computation and physical processes by networking. In CPS, various embedded devices with computational components are networked to monitor,...

User Association and Self Organizing Network for (Beyond) 4G Wireless Network

In this talk, we discuss a mechanism for self organizing network (SON) for (beyond) 4G wireless network. We propose a framework for user association in infrastructure-based wireless networks, specifically focused on flow-level cell load balancing under spatially inhomogeneous traffic distributions. Our work encompasses several different...
