Most network protocols are uni-modal: they employ a single set of algorithms that allows them to cope well only within a narrow range of operating conditions. This rigid design renders these protocols inefficient in the face of widely varying operating environments or in conditions different from the ones for which they are optimized. Such uni-modal protocols have great difficulty in the mobile...

By using binary ethanol/water mixtures, the separation performance of two improved commercial pervaporation embranes (PERVAPTM) are presented. Separation performance data are analyzed and compared as a function of operating conditions. The effect of initial feed concentration on the separation performance and the effect of feed concentration on apparent activation energy are presented. For memb...

The Fischer-Tropsch synthesis is a catalytic process that can produce a fuel similar to fossil fuels by using primary sources such as agricultural waste and carbon sources that can convert into synthesis gas by superheated steam. All fuel derivatives can be supplied through the Fischer-Tropsch reaction. The synthesis produces a variety of hydrocarbons via parallel and sequential reactions. Howe...

oily wastewaters from oil refineries and oil distribution centers are one of the most important environmental concerns in recent decades; therefore, it is critical to treat these types of wastewaters. in this study, the performance of different polyethersulfone hollow fiber membranes in oily wastewaters treatment was investigated and the effects of operating conditions such as transmembrane pre...

Since detecting race conditions in a multithreaded or multiprocess program is an NP-hard problem, there is no efficient algorithm that can help detect race conditions in a program. As such, there are no easy-touse pedagogical tools. Most operating systems and concurrent programming textbooks only provide a formal definition and some trivial examples. This is insufficient for students to learn h...

In a recent paper we have introduced a postprocessing procedure for the Galerkin method for dissipative evolution partial differential equations with periodic boundary conditions. The postprocessing technique uses approximate inertial manifolds to approximate the high modes (the small scale components) in the exact solutions in terms of the Galerkin approximations, which in this case play the r...

In the present research, performance validation of a Heating, Ventilation, and Air Conditioning (HVAC) system operating in a library building was conducted. The operating HVAC system was studied in terms of the provided indoor air conditions and energy consumption level. The fieldwork measurements showed that the HVAC system is not capable of providing the desired indoor air conditions based on...

One of the key elements in production planning hierarchy is master production scheduling. The aim of this study is to evaluate and compare thirteen alternative MPS development methods, including multi-objective optimization as well as twelve heuristics, in different operating conditions for multi-product single-level capacity-constrained production systems. We extract six critical criteria from...
