sumption in active mode as a tradeoff to increased performance, but any power consumed when the system is idle is a complete waste and ideally should be avoided by turning the system off. A typical current system is so complex that parts of it will likely be inactive even during active periods, and they can be turned off to reduce power with no impact on performance. The introduction of finer-g...

purpose : to evaluate the accuracy of the two methods the clinical history method (chm), and the contact lens method (clm), in refractive corneal power determination and comparing the accuracy of srk ii, srk t and holladay ii (h ii) formulas for intraocular lens (iol) power calculation in patients who had laser in situ keratomileusis (lasik) surgery for myopia with or without astigmatism method...

following the september 11th events when the united states managed to forge an international coalition against terror within the framework of operation enduring freedom, attacking afghanistan, the general perception was that the united states would be able soon to destroy the taliban in afghanistan and remove the shades of war and insecurity from afghanistan. however what occurred was the colla...

political power is considered as one of the most fundamental public law vocabulary, as far as the separation of political power and public law seems impossible. meanwhile it seems that this concept as the fundamental concept of public law; varies in islamic and liberal thought and there is a serious conflict between them. analysis of this claim requires a proper understanding of the concept of ...

this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...

let r be a ring, m a right r-module and (s,≤) a strictly ordered monoid. in this paper we will show that if (s,≤) is a strictly ordered monoid satisfying the condition that 0 ≤ s for all s ∈ s, then the module [[ms,≤]] of generalized power series is a uniserial right [[rs,≤]] ]]-module if and only if m is a simple right r-module and s is a chain monoid.

this paper argues for a broader emphasis on sustainable security and smart power, for examining both opportunities as well as threats to security. sustainable security is a new concept in the security studies. deep attention to all possible threats against human life is necessary for continuation of security in a sustainable and dynamic base. this aim can be achieved in a highest level by mergi...

some geothermal reservoirs have temperatures below boiling point and therefore natural steam can not be produced for power generation. refrigerant power cycles may be then employed to recover low temperature heat. in this article study is made of the power cycles of six different relligrants and most suitable refrigerants for this purpose are suggested
