Mutual Fund industry plays a pivotal role in optimal allocation and channelization of available idle resources in the economy. This role becomes much stronger in the developing economies like Pakistan where the prospective investors do not have much investment knowledge, information, and facilities to invest in the capital markets neither they have risk aptitude for direct investments in risky ...

Fixed-point hardware implementations of signal processing algorithms can often achieve higher performance with lower computational requirements than a floating-point implementation. However, the design of such systems is hard due to the difficulty of addressing the quantization issues. This paper presents an optimization approach to determining the wordlengths of fixed-point operators in a spee...

An approximate numerical^graphical solution was made for the motion of a human aortic valve leaflet in a meridional plane through the center of the sinus of Vabalva. The observed buckling, whipping action of the leaflet was obtained. Of primary significance in the results was the location and the determination of the maximum curvature of the leaflet in this plane, since this point corresponds t...

To satisfy the design requirements for a hydropneumatic spring damper valve, inlet–outlet pressure drop (ΔP) and axial force on spool (FZ) of valve were investigated using fluid–solid coupling simulations multi-objective optimization, along with effects diameters three internal holes (DA, DB, DC) in ΔP FZ. First, meshed computational fluid dynamics model was established based its geometric stru...

an experiment featuring waterhammer in viscoelastic pipes is presented in which the effects of pipe-wall viscoelasticity on waterhammer pressures are investigated. a large-scale pipeline apparatus made of polyvinyl chloride (pvc) at deltares, delft, the netherlands, has been used to carry out waterhammer experiments. tests have been conducted in a reservoir-pipeline-valve system consisting of a...

In order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. In this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. Two elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-d...

This article presents a new investigation to the linear mixed model y = Xβ + Zγ + ε with fixed effect Xβ and random effect Zγ under a general assumption via some novel algebraic tools in matrix theory, and reveals a variety of deep and profound properties hidden behind the linear mixed model. We first derive exact formulas for calculating the best linear unbiased predictor (BLUP) of a general v...
