The effects of energy supplementation on Leu utilization in growing steers were evaluated in 2 experiments by using 6 ruminally cannulated Holstein steers. In Exp. 1, steers (initial BW = 150 +/- 7 kg) were limit-fed (2.3 kg of DM/d) a diet based on soybean hulls and received a basal ruminal infusion of 100 g of acetate/d, 75 g of propionate/d, and 75 g of butyrate/d, as well as abomasal infusi...

The main goal of this paper is to structurally analyze impact of DSM programs on reliability indices. A new approach is presented to structurally decompose reliability index Expected Energy Not Supplied (EENS) by using Monte Carlo simulation. EENS is decomposed into two terms. The first term indicates EENS which is caused by generation contingencies. The second term indicates EENS which is caus...

Yet if we have learned anything from engineering, biology and physics, information is just as crucial an ingredient. The robot at the automobile factory is supplied with metal and plastic but can make nothing useful without copious instructions telling it which part to weld to what and so on. A ribosome in a cell in your body is supplied with amino acid building blocks and is powered by energy ...

This paper presents an operation strategy for a power system supplied from 100% renewable energy generation in Kitami City, a cold region in Japan. The main goal of this work is the complete elimination of the CO2 emissions of the city while keeping the power frequency within prescribed limits. Currently, the main energy related issue in Japan is the reduction of CO2 emissions without depending...

VLSI devices with high power demands have several important drawbacks; power to run the chip must be supplied externally, and power is dissipated as heat, which must be removed from the circuit. Processor architects tend to view these issues as circuit technology or packaging problems. However, these solutions are limited, and do not necessarily provide insight into more direct approaches to en...

This paper describes a case study of improving the asset performance of ethylene cracking furnaces through energy saving by Yokogawa’s Asset Performance Diagnostics service, one of the services of Plant Asset Effectiveness Optimization Services, InsightSuiteAE. During regular maintenance of ethylene cracking furnaces, steam and air are supplied to tubes for decoking to burn and remove coke whic...

A fuel cell is essentially a compact electrochemical “factory” that takes fuel as input and produces electricity as output (see fig. 1). Like a factory, a fuel cell will continue to churn out product (electricity) as long as raw material (fuel) is supplied. This is the key difference between a fuel cell and a battery. While both rely on electrochemistry to work their magic, a fuel cell is not c...

Wireless sensor networks (WSNs) have a wide range of potential applications, a majority of which may be required to survive for a pre-configured lifetime since it is hard or costly to re-deploy sensor nodes to where a sensing hole has taken place. A sensing hole may occur when specific nodes suffer more traffic load than others and thus exhaust initially supplied energy. We propose an adaptive ...
