Small cells are being deployed at increasing rates to meet the multimedia communication demand in mobile network, but inter cell interference is a challenge in the heterogeneous network. In this study, we proposed a novel method to solve the small cell placement and the interference management problem. In order to achieve a tradeoff between the quality of service of cell edges user and the whole system...
The world’s appetite for abundant-data computing, where a massive amount of structured and unstructured data is analyzed, has increased dramatically. The computational demands of these applications, such as deep learning, far exceed the capabilities of today’s systems, especially for energy-constrained embedded systems (e.g., mobile systems with limited battery capacity). These demands are unlikely...
The ability to learn from few examples, known as one-shot learning, is a hallmark of human cognition. Hyperdimensional (HD) computing is a brain-inspired computational framework capable of one-shot learning, using random binary vectors with high dimensionality. Device-architecture co-design of HD cognitive computing systems using 3D VRRAM/CMOS is presented for language recognition. Multiplication-addition-permutation...
Wireless body sensor nodes (WBSNs) are miniaturized devices that are able to acquire, process and transmit bio-signals (such as electrocardiograms, respiration or human-body kinetics). WBSNs face major design challenges due to extremely limited power budgets and very small form factors. We demonstrate, for the first time in the literature, the use of disruptive nanotechnologies to create new nano-engineered...
A distributed control and coordination architecture for integrating inherently variable and uncertain generation is presented. The key idea is to distribute the intelligence into the periphery of the grid. This will allow coordination of generation, storage, and adjustable demand on the distribution side of the system and thus reduce the need to build new transmission facilities to accommodate large...
Analysis of power grid IR-drop during scan test application has drawn growing attention because excessive IR-drop may cause a functionally correct device to fail at-speed testing. The analysis is challenging since the power grid IR-drop profile depends on not only the switching cells locations but also the power grid structure. This paper presents a scalable implementation methodology for quantifying...
