Research ArticleOpen accessIn the abstractNumerical Modeling of Groundwater Flow in Karst Aquifer, Makeng Mining AreaF. M. Rani, Z. H. ChenProblem statement: Making iron ore is one of the largest mining projects in south east of china. Due to the development of mining activities in that site, it has become necessary to increase the depth of exploration. Increase the exploration depth makes the mining tunnels subjected to the karst water inrush. Approach: A hydrological and a hydrogeological model for the … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvanced Information Technology of Slot-Switching Network Schemes for on All-Optical Variable-Length PacketSoung Yue Liew, Edward Sek Khin Wong, Choong Kwai FattProblem Statement: The purpose of this paper was to investigate all optical packet switching, because it was the key to the success of the future Internet. It can meet the stringent bandwidth requirement of future Internet applications, such as real-time video streaming. Due to the lack of optical Random Access Memory (RAM), however, the all-optical schemes studied in the literature … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Crude Oil and Spent Oil on Clarias garipinus: A Typical Marine FishA. M. Gbadebo, A. M. Taiwo, O. B. OlaProblem statement: Petroleum hydrocarbon and petroleum residue (i.e., spent oil) remains the foremost pollutants to the fish communities in various aquatic media-ponds, streams, rivers, creeks, coastal and marine environments through indiscriminate disposal of oil contaminated drilling muds, cutting and oil spillages. Approach: Also, the spent oil enters into aquatic media through run-off following unguided disposal. Both the petroleum hydrocarbon and … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Continuing Losses Estimation Using Initial Loss-Continuing Loss Model for Medium Sized Rural CatchmentsMahbub Ilahee, Monzur Alam ImteazProblem statement: The rainfall based design flood estimation techniques are commonly adopted in hydrological design and require a number of inputs including information on soil loss characteristics. Approach: A conceptual loss model known as the ‘Initial Loss-Continuing Loss (IL-CL) model’ is widely used in Australia. Results: The Initial Loss (IL) occurs at the beginning of the rainfall event, prior to … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn situ Shear Tests of Soil Samples with Grass Roots in Alpine EnvironmentE. Comino, A. DruettaProblem statement: The presence of vegetation increases the soil burden stability along slopes and reduces soil erosion. Its contribution is due to mechanical (reinforcing soil shear resistance) and hydrologic controls on streambank and superficial landslides. This study presented the results carried out from experimental in situ test focused to study the increased shear resistance of soil blocks due to root-reinforcement. … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach to Improve the State Scalability of Source Specific MulticastS. A. Al-Talib, B. M. Ali, S. KhatunProblem statement: Source Specific Multicast (SSM) is an acceptable solution for current multicast applications; since the driving applications to date are one to many, including Internet TV, distance learning, file distribution and streaming media. Approach: It was useful for billing, address allocation and security. SSM still had serious state scalability problem when there were a large number of simultaneous on-going … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 6,820 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Flutter Derivatives of Bridge Decks in Wind Tunnel Test by Stochastic Subspace IdentificationT. Janesupasaeree, V. BoonyapinyoProblem statement: Flutter derivatives are the essential parameters in the estimations of the flutter critical wind velocity and the responses of long-span cable supported bridges. These derivatives can be experimentally estimated from wind tunnel test results. Generally, wind tunnel test methods can be divided into free decay test and buffeting test. Compared with the free decay method, the buffeting test … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Social Adjustment of the Kuy People to a Multicultural Context in Southern Isan, ThailandWilart Pothisan, Art Nantajak, Prasopsuk Rittidet, Budsakorn SaenyabudThe state had paid much attention on economy by building a network of roads between the province, the district and the village for the Kuy people in Ban Treum. The state established a health center to provide for the people with modern medical care and malaria prevention. And the external streams had more effects on their communities. Therefore, Kuy had … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 8,545 accessesView PDFCite
