Hybrid NEMS-CMOS Architectures for Ultra Low Power Smart Systems: Architectures for Ultra Low Power Smart Systems

The availability of inexpensive and powerful processors provides the means for the computation ecosystem to change its fundamental paradigm towards the Internet of Things (IoT) where ubiquitous nanosystems add intelligence to every object that surrounds us. The new trend for most of those systems is to autonomously operate into a “zero-power”...

Thermal-Aware Design and Runtime Management of 3D Stacked Multiprocessors

The sustained increase in computational performance demanded by next-generation applications drives the increasing core counts of modern multiprocessor systems. However, in the dark silicon era, the performance levels and integration density of such systems is limited by thermal constraints of their physical package. These constraints are more...

Composable and Predictable Power Management

The functionality of embedded systems is ever growing. The computational power of embedded systems is growing to match this demand, with embedded multiprocessor systems becoming more common. The limitations of embedded systems are not always related to chip size but are commonly due to energy and/or power constraints. While it can be possible to...

Important Issues and Economic Study of Ship DC Distribution System with Variable-Speed Diesel Generator

In a traditional AC distribution system, the synchronous frequencies of the generators are coupled with the system frequency, and thus the diesel engines are kept at a constant speed. In a Dynamic Positioning (DP) vessel such as a Platform Supply Vessel (PSV), the diesel engines sometimes work at the partial load condition. The efficiency of...

An Empirical Approach Towards Zero Energy Networks (ZEN)

Information and Communication Technology (ICT) is changing the way we live and has become an essential part of our life. With the advent of Internet of Things (IoT), and Wireless Sensor Networks (WSN) in particular, the number of devices that are networked is increasing exponentially over the years. With the increase in number of ICT devices...

Genset-Solar-Wind Hybrid Power System of Off-grid Power Station for Rural Applications

A hybrid power system (HPS) which consists of diesel Genset, PV-arrays and wind turbines with energy storing and power electronic devices is discussed in this paper. An inventory of different connection topologies is made for some of the sources generate AC power and others generate DC power. By comparative study on the system efficiency, the...
