  • Pressure and temperature effects on corona onset voltage in electrostatic

    • Abstract: Corona onset voltage is one of the most important factors that determine the charging toxic particle in an industrial application. Electrostatic precipitators (ESP) remove the suspended particle with a gas inlet. This paper developed Peeks formula to estimate the maximum electric field near the discharge wire in corona discharge models, the values of maximum electric field and corona onset v...

  • Hydrogeochemical investigation and characterization of shallow groundwater
           within Ankpa Town, North Central Nigeria

    • Abstract: Physico-chemical analysis of groundwater samples from Ankpa, north central Nigeria was carried out to investigate the quality of the water for drinking and irrigation purposes. The results revealed water of average low pH, indicating slightly acidic conditions of the water. The water is soft, and it is characterized as Na++K - HCO3 type. It is good for drinking and other domestic uses. Four ...

  • Performance evaluation of law enforcement agency on crime information
           management using queuing network model

    • Abstract: One of the greatest challenges facing every society today is crime control and management. It could be as little as pickpocketing, or human trafficking, or even as deadly as terrorism. As criminals perfect ways of avoiding being detected, Law Enforcement Agencies (LEAs) must adopt innovative ways on crime prevention and control. This research applies Queuing Network (QN) model to evaluation ...

  • Effect of Co component in Co-Ag granular thin films on visible-light
           reflection applied by magnetic field

    • Abstract: The reflection of visible light (wavelength from 350 to 800 nm) on magnetic granular thin films Cox-Ag1-x with x from 0 to 35 at % was studied. Dependence of reflection (R) is strong on magnetic and percentage of Co in the thin films, R strongly increase in wavelengths 560 and 660 nm. In this paper, some arguments relating to the spin-plasmon phenomenon were used to explain the results. ...

  • Partial and total mass attenuation coefficients, effective atomic number
           and effective electron number of different Maraging steel compositions

    • Abstract: The total and partial mass attenuation coefficients for different Maraging steel compositions have been determined by using the WinXCom and MCNP5 programs. The effective atomic number, Zeff, and effective electron number, Neff, for the studied steels have been determined via the total mass attenuation coefficients /, the total atomic and electronic cross sections (a and e) of the investigate...

  • Multiples in Onshore Niger Delta from 3D prestack seismic data

    • Abstract: The presence of multiples has been investigated in Onshore Niger Delta using 3D seismic data. The aim of the study was to investigate the characteristics of reflection events beyond 3s two way time on seismic data behind the boundary faults associated with the shadow zone. This involves detailed velocity analysis on semblance plot panel and accounting for moveouts due to reflections away and...

  • Calibration and estimation of efficiency of Geiger Muller counter using a
           standard radioactive source

    • Abstract: The beta counting system uses a Geiger-Muller (GM) tube to detect the presence of beta contamination present in filter paper samples or in planchet samples. The counting system is enabled with a provision to count the samples at various distances from the detector to the sample position. The efficiency of the counting system is provided by the manufacturer at the time of procurement which is...

  • Energy saving by applying the fuzzy cognitive map control in controlling
           the temperature and humidity of room

    • Abstract: This paper investigated the implementing of soft computing methodology of fuzzy cognitive map on controlling parameters of heating, ventilating and air-conditioning systems. In the past few years, many researches have been done on application of different controllers on heating, ventilating and air-conditioning system as a more energy consuming part of the building automation system. Unlike ...

  • Numerical modeling and determination of parameters characteristic of a
           photovoltaic module LRAER (FST Nouakchott)

    • Abstract: The main objective of this work is to study, develop and establish an approach through the mathematical model of performance CENERG under the term (MC). This model is used to characterize the parameters of photovoltaic systems in the literature. For this, we have considered the required performance is normally measured in standard test conditions (STC), where an average solar spectrum AM 1.5...

  • Sandwich panels from cork and polyester in presence of epoxy resin as
           interfacial adhesive

    • Abstract: This work presents an experimental study to determine the mechanical properties in bending, tension, compression and shear of a new sandwich material based on natural materials (jute and cork). The sandwich material is made basically of natural materials whose soul is agglomerated cork white (located in Jijel, East of Algeria) and the skins are woven jute with ortho phthalic polyester resin....
