Well Screens and Gravel Packs
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 5
The purpose of well screens and gravel packs is to maintain open access within the aquifer ensuring that thorough development of the well is not impeded by sand. Where a well draws on unconsolidated sands and gravels, or other friable materials. The production section is characterized by mainly medium to coarse grained sandstone, the uniformity coefficient efficient ranging from 1.44 to ...

Investigation ofWindow Effects and the Accurate Estimation of Spectral Centroid
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 4
The spectral centroid is one of the useful low level features of a signal that was proposed for speech-music classification, speech recognition and musical instrument classification, and was also considered one of the lowlevel features to describe the audio content in MPEG-7 Content Description and Interface Standard. When the spectral centroid is computed from practical data, the estima...

Characterization of Fuel Properties for the Biodiesel-Petro-Diesel Blends Dosed with the FPC
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 4
The effect of the Fuel Performance Catalyst (FPC) on the different diesel properties namely density, viscosity and flashpoint of biofuel has been investigated. The biodiesel-petro-diesel blends concentrations (Vol %) of B10, B20 and B30 have been analyzed with the pure biodiesel (B100) and petro-diesels (B0) as upper and lower boundaries respectively. The results indicated that the FPC: ...

Theoretical and Experimental Study of the Primary Stageof the Gasoline Fuel Spray
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 4
The fuel spray in gasoline engines problem has been an issue of importance for creating a suitable mixture during the engine load and speed variation to avoid knocking. This paper describes theoretical and experimental investigations for an important stage of injected gasoline called the primary fuel spray. This stage two dimensional (2D) is challenging because of the difficulty in deter...

Security in Untrusted Updated Environments
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 3
At present days, technology growth was rapid and its use is very often. So the attacks were concentrated on the user systems mainly by using the network applications. Bugs in the application of a network can ruin the applications in a system that are running. When the user is in the use of internet or e-commerce sites, etc.., the applications will be considered that they are in an unsafe...

Water Resource Conflict in the Amazon Region: The Case of Hydropower Generation and Multiple Water uses in the Tocantins and Araguaia River Basins
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 2
The guarantee of multiple water use is one of the main objectives of the Brazilian system of managing water resources. However, it is still unclear how to reach these objectives regarding hydropower plants. This paper introduces a method for support of hydropower plants taking into account the compatibility with multiple water uses. It also introduces a computational tool based on the pr...

Kinetic and Thermodynamic Studies of Removal of Cadmium Ion Onto Synthetic Pure Zeolite from Rice Husk Ash, Thailand
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 2
The rice husk ash (RHA) waste from biomass power plant in Thailand is still underutilized leaving disposal problems. Indeed, this material content high silica inside it has a possibility to become a potential zeolites precursor. In this study, small particle of RHA has been reused to prepare a Na-A and Na-X zeolites with high purity using two step method hydrothermal treatments. First, R...

Study of Two-metal (Cu-Ag) Micro Heat Pipe of Convergent-Divergent Circular Cross Section Using Different Working Liquids of Low Boiling Point
Published In: GJRE Part: J: General Engineering Volume: 15 Issue: 2
With the modernization of electronic machines, the size or weight to efficiency ratio is getting small enough to leave the equipment highly thermally stressed. To manage this stress, an experiment on thermal effects of a two-metal (Cu-Ag) micro heat pipe (TMMHP) of convergent-divergent cross section, which provides variable conductivity and pressure gradient, at steady state are investig...

Notable disasters - The sinking of RMS Titanic in 1912, with 1,517 fatalities, is probably the most famous shipwreck, but not the biggest in terms of life lost. The wartime sinking of the Wilhelm Gustloff in January 1945 in World War II by a Soviet Navy submarine, with an estimated loss of about 9,400 people, remains the greatest maritime disaster ever. In peacetime, the 1987 loss of the...
