Estimating the operating efficiency of an induction machine is of prime importance for modern plant management. An extensive testing program of present efficiency estimation techniques was performed at the Motor Systems Resource Facility (MSRF), during which serious shortcomings of the existing techniques were identified. The objective of the work of...
A computer simulation program, Controlled Atmosphere Simulation (CAS), was written in Microsoft Visual Basic 3.0, Professional Edition to evaluate energy use by three type of atmosphere generators used in fruit storage warehouses. The program consists of pulldown time and energy use models for a membrane air separator, an ammonia fractionating...
In this thesis, we develop a simulator for estimating the energy consumed in executing tasks on a mobile device - the Palm Pilot. We measured the energy consumed by each instruction of the device's assembly language and incorporated these measurements into a public domain emulator for the Palm Pilot. This...
Air compressors are a significant industrial energy user and therefore a prime target for industrial energy audits. The project goals were to develop a software tool, AIRMaster, develop a methodology for performing compressed air system audits, and conduct field audits to refine the methodology and assess savings potential from six...
This work presents improvements to a multi-core performance/power simulator. The improvements which include updated power models, voltage scaling aware models, and an application specific benchmark, are done to increase the accuracy of power models under voltage and frequency scaling. Improvements to the simulator enable more accurate design space exploration for...
With the rapid increase of the world energy demand and
consumption, the method and techniques to analyze, improve
and optimize energy conversion systems have to deal not only
with direct fuel exergy (energy) consumption, but also with
other resources, which have associated exergy consumptions,
and with environmental impacts, such as...
As advanced wired and wireless communication systems attempt to achieve higher performance, the demand for high resolution and wide signal bandwidth in their associated ADCs is strongly increased. Recently, time-domain quantization has drawn attention from its scalability in deep submicron CMOS processes. Furthermore, there are several interesting aspects of time-domain...
Low power, high speed serial transceivers are employed in a wide range of applications ranging from chip-to-chip, backplane, and optical interconnects. Apart
from being capable of handling a wide range of data rates, the transceivers should
have low power consumption (mW/Gbps) and be fully integrated. This work
discusses enabling techniques...
