One of the most interesting results from the NA49 energy scan program at the CERN SPS is an anomalous behaviour of the energy dependence of the 〈K〉/〈π+〉-ratio in central Pb+Pb reactions [1]. Also, results on the energy dependence of K−φ-, Λ-, Λ̄-, andΩ-production have been reported [2, 3, 8]. The question whether all strange particles exhibit rapid changes in their yield relative to pions and wh...

A method of estimating the annual energy requirements for a dairy herd in Queensland was developed from nutritional standards and observed correlations of liveweight and milk production obtained from farm survey data. Maintenance energy requirements were calculated from liveweight estimated from milk yield, and together with energy requirements for milk yield, and allowances for walking and liv...

Electron clouds pose a significant problem for high-energy lepton colliders, including the proposed International Linear Collider. The Cornell Electron Storage Ring Test Accelerator is able to study the dynamics of such clouds by measuring their effect on the tune of particle bunch trains. Key parameter values characterizing electron clouds can be estimated using numerical simulations of the ob...

energy method of evaluation is widely employed in analyzing problems associated with sustainable agriculture. in this study, energy ratio (er) of dryland wheat for three regions of eghlid township was quantified. the total cropping area of eghlid is nearly 8282 hectares comprised of: khosrowshirin (5000 ha), sedeh (1682 ha) and dezhkord (1600 ha). the corresponding values of wheat yield in thes...

Mid-infrared laser ablation of water-rich targets at the maximum of the 2.94 mm absorption band is a two-step process initiated by phase explosion followed by recoil pressure induced material ejection. Particulates and/or droplets ejected by this high temperature high pressure process can be ionized for mass spectrometry by charged droplets from an electrospray. In order to gauge the internal e...

As circuit parametric variations aggravate in advanced technology, yield emerges as an important figure-of-merit in circuit design. Based on a 130nm technology, the yield-energy-delay tradeoffs in low-power circuit optimization are investigated. Using a log-normal statistical model, Monte-Carlo analyses are performed on typical circuit examples, including an inverter chain, NAND gate, and 4-bit...

Nowadays, in consideration of environmental issues and limitation of fossil fuels, there is a particular consideration of renewable energy including Ocean Energy, that can extracted going through various methods such as Wave Energy, Tidal Energy, Salinity Gradient, OTEC: Ocean Thermal Energy Conversion.Herein this research, operation of OTEC Method in Southern Caspian Sea has been discussed. Fo...

In this paper the maximum power point tracking (MPPT) algorithms for wind energy systems arereviewed. As the amounts of power produced in wind power plants is changing due to theinstantaneous changing nature of the wind, it is desirable to determine the one optimal generatorspeed that ensures maximum energy yield. Thus, it is important to include a controller that cantrack the maximum peak rega...
