Difficulties for Commercial Takeoff of Hydrogen Energy

On the Difficulties of Codifying Commercial Law

Energy Management for Commercial Servers

I n the past, energy-aware computing was primarily associated with mobile and embedded computing platforms. Servers—high-end, multiprocessor systems running commercial workloads—typically included extensive cooling systems and resided in custom-built rooms for high-power delivery. In recent years, however, as transistor density and demand for computing resources have rapidly increased, even hig...

NO and NO2 emission ratios measured from in-use commercial aircraft during taxi and takeoff.

In August 2001, the Aerodyne Mobile Laboratory simultaneously measured NO, NO2, and CO2 within 350 m of a taxiway and 550 m of a runway at John F. Kennedy Airport. The meteorological conditions were such that taxi and takeoff plumes from individual aircraft were clearly resolved against background levels. NO and NO2 concentrations were measured with 1 s time resolution using a dual tunable infr...

Hydrogen for Synthetic Fuels via Nuclear Energy

Fluctuations in availability and recent increases in price of petroleum have had profound effects on the national economy. As synthetic fuels, in particular, hydrogen, become increasingly attractive, nuclear energy has a role in developing such fuels. It is postulated that the nuclear radiation of the fission process itself can be utilized directly in fluid fueled devices or radiation and heat ...

Selecting the appropriate scenario for forecasting energy demands of residential and commercial sectors in Iran using two metaheuristic algorithms

This study focuses on the forecasting of energy demands of residential and commercial sectors using linear and exponential functions. The coefficients were obtained from genetic and particle swarm optimization (PSO) algorithms. Totally, 72 different scenarios with various inputs were investigated. Consumption data in respect of residential and commercial sectors in Iran were collected from the ...
