Research ArticleOpen accessAll words, across the recordA Linear Model for Moving Measurements Estimation in Urban Climate StudiesClaudia Cotrim Pezzuto, Lucila Chebel Labaki, Lia Toledo Moreira Mota, Alexandre Alexandre de Assis MotaProblem statement: Several methods can be adopted to study the variations in urban climate. The mobile measurement method is one of them, involving information provided by moving measurements of air temperature, that are taken in points defined along pre-established routes and also data from fixed-point temperature recording stations. Because moving measurements are made in different times along the measurement process, … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,038 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDevelopment of a Soft-Computer Numerical Control System for Micro-Electrochemical MachiningYukui Wang, Hui Chen, Zhenlong Wang et al.Problem statement: In this study a kind of soft Computer Numerical Control (soft-CNC) system for micro Electrochemical Machining (micro-ECM) based on RT-Linux platform is developed. Approach: Dual-kernel structure of System is adopted: Linux and RT-Linux are used to realize timesharing tasks and real-time tasks separately. Results: The CNC Graphical User Interface (GUI) is designed by Qt and runs on Linux … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 11,042 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPreparation and Polishing Properties of Spherical Porous Silica AbrasiveHong Lei, Hu Li, Ping Liu, Ruling ChenProblem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 9,285 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFully Integrated Hydrocarbon Reservoir Studies: Myth or Reality?Christoforos Benetatos, Dario VibertiProblem statement: In the petroleum industry and especially during reservoir studies, data coming from different disciplines must be combined in order to generate a model that is representative of the reservoir being studied and can be used for defining the most viable development strategy of the field from both an economic and technical standpoint. Each of these disciplines represents an … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 9,975 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDetermination of Kinetic Parameters of a Super Heavy Chisel Plow Under Various Operating ConditionsS. A. Al-Suhaibani, A. Al-Janobi, A. E. GhalyProblem statement: Tillage is a process of creating a desirable soil condition for seed germination and growth. The tillage of soil is considered to be one of the biggest farm operations as the tillage operation requires the most energy on the farm. Chisel plow is widely used by farmers as a primary tillage tool. Performance data for chisel plow operation … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,652 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Environmental Parameters on hydrogen Production using Clostridium Saccharoperbutylacetonicum N1-4(ATCC 13564)Walid M. Alalayah, Mohd Sahaid Kalil, Abdul Amir H. Kadhum et al.Problem statement: Hydrogen gas production by Clostridium can be improved by several ways through media formulation, or suitable environment condition. This study was carried out to investigate the environmental factors effects on hydrogen production using Clostridium saccharoperbutylacetonicum N1-4 (ATCC 13564). Approach: The environmental factor studied includes initial substrate concentration, initial medium pH, temperature, sparging nitrogen and addition of Fe2+. Results: … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,775 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInfluence of Heat Treatment in Sintering Process on Characteristics of Al2o3-Zro2 Ceramics SystemsA. Rittidech, T. TunkasiriAl2O3-ZrO2 ceramics containing 5-50 mol% ZrO2 were prepared by solid state reaction method. The bulk density, average grain size and microhardness of Al2O3-ZrO2 ceramics system as function of ZrO2 content were investigated. The dense Al2O3-ZrO2 ceramics were successfully by means of carefully control processing parameters that include sintering temperature and heating/cooling rates. These ceramics with higher ZrO2 content was obtained … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,008 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAir Blast Freezing of Lime Juice: Effect of Processing ParametersWasan Theansuwan, Kitrichai TriratanasirichaiThis research characterized the effects of air velocity and lime juice layer thickness on freezing time. In the experiment, the air velocity of the freezer and the thickness of the lime juice layer were set to be 4-12 m sec-1 and 4-10 mm, respectively. The temperatures of the lime juice were measured from 15°C until it reached -20°C and were … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,449 accessesView PDFCite
