This research aims to create lightweight concrete mixtures containing waste from local sources, such as expanded polystyrene (EPS) beads and plastic fibers (WPFs), all are cheap or free in the Republic of Iraq without charge. The modern, rigid, mechanical properties LWC were investigated, results evaluated. Three made, each with different proportions (0.4%, 0.8%, 1.2%), addition a mixture steak...

In recent years, determining an appropriate supplier has become a crucial strategic consideration in a competitive market – with data envelopment analysis (DEA) methods increasingly important in this respect. DEA traditionally requires that the values for all inputs and outputs be known exactly. However, this assumption may not be true, because data in many real applications cannot be precisely...

This study is aimed to develop a computer program analyze the color properties of raster images histological microspecimens used in pathological anatomy and forensic medicine. When developing program, we system for building client applications – Windows Presentation Foundation (WPF). The allows you create with visually attractive user interaction capabilities. programming language C#, as well b...

The detailed modeling of power electronic (PE) devices poses challenging problems to an efficient transient simulation large-scale PE-dominated systems. As PE paradigm, a multiscale methodology the modular multilevel converter (MMC) for simulating diverse transients from low-frequency oscillations up high-frequency switching events in MMC high-voltage direct current (HVdc) system is developed, ...

Nowadays, with large-scale offshore wind power farms (WPFs) becoming a reality, more efforts are needed to maintain a reliable communication network for WPF monitoring. Deployment topologies, redundancy, and network availability are the main items to enhance the communication reliability between wind turbines (WTs) and control centers. Traditional communication networks for monitoring and contr...

The aim of this study was to investigate respirator filter and faceseal penetration of particles representing bacterial and fungal spore size ranges (0.7-4 mum). First, field experiments were conducted to determine workplace protection factors (WPFs) for a typical N95 filtering facepiece respirator (FFR). These data (average WPF = 515) were then used to position the FFR on a manikin to simulate...

Speech enhancement has an increasing demand in mobile communications and faces a great challenge in a real ambient noisy environment. This paper develops an effective spatialfrequency domain speech enhancement method with a single acoustic vector sensor (AVS) in conjunction with minimum variance distortionless response (MVDR) spatial filtering and Wiener post-filtering (WPF) techniques. In remo...

Developments in the wind power industry have enabled a new generation of wind turbines with longer blades, taller towers, higher efficiency, and lower maintenance costs due to the maturity of related technologies. Nevertheless, wind turbines are still blind machines because the control center is responsible for managing and controlling individual wind turbines that are turned on or off accordin...

In the banking industry, the production process can be described as a two-stage process. There are a number of published data envelopment analysis (DEA) papers that study the bank performance with two-stage model. However, none of them is applied to identify bank failure. In fact, only one of them deals with negative profit data. In the real world, failed banks or firms often produced negative ...
