Research ArticleOpen accessIn the abstractInverse Discrete Fourier Transform-Discrete Fourier Transform Techniques for Generating and Receiving Spectrally Efficient Frequency Division Multiplexing SignalsSahmed IdarwazehProblem statement: Spectrally Efficient Frequency Division Multiplexing (SEFDM) system promises bandwidth savings by multiplexing overlapped non-orthogonal sub-carriers. However, the loss of orthogonality results in increasing the complexity of generation and detection of the signal. In this work, we propose simple framework for the generation of the SEFDM signal based on the Inverse Discrete Fourier Transform (IDFT). Approach: This study further … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Jul 2012 · 8,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe International Multimodal Transport of Hazardous Goods and WasteGiancarlo Carosso, Cesare Luceri, Pierpaolo OresteThe international multimodal transport of hazardous goods and waste is a sector of remarkable economic importance. This transport activity is connected to several productive sectors and it can have considerable repercussions on the environment and health as well as on the safety of the workers and third parties that study in the same field. A certain part of the transport … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 10 Jul 2012 · 7,118 accessesView PDFCite
Research ArticleOpen accessIn the abstractClamshell vs. Backhoe Excavation of Permeable Reactive BarriersRajandrea Sethi, Steve Day, Antonio Di MolfettaProblem statement: Permeable Reactive Barriers (PRBs) were one of the most widespread solutions for the remediation of contaminated aquifers. Although, a variety of excavation methods had been developed, backhoe (hydraulic excavators) were commonly used for the construction of PRBs in North America. Approach: In Europe, the most common method of slurry excavation was with a hydraulic grab and crane. The … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 4 Nov 2011 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Soil Moisture Sensors under Intelligent Irrigation Systems for Economical Crops in Arid RegionsMohamed Said Abdall El Marazky, Fawzi Said Mohammad, Hussein Mohamed Al-GhobariProblem Statement: In irrigation water management, irrigation water use represents a substantial opportunity for agriculture water savings. Automation of irrigation systems, based on Soil Moisture Sensors Systems (SMSS) has the potential to provide maximum water use efficiency by maintaining soil moisture at optimum levels. Approach: The objective of this research was to evaluate the performance of soil moisture sensors under … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractMalaria and Climate Change: Discussion on Economic ImpactsMd. Shahin Mia, Rawshan Ara Begum, Ah-Choy Er et al.Problem statement: Climate change is a global environmental change that is adversely affecting human health by causing various health impacts in countries throughout the world. Climate is the most influential driving force of vector-borne diseases such as malaria. Changes in climate factors substantially affect reproduction, development, distribution and seasonal transmissions of malaria. Climate change increases the outbreak of malaria which … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,584 accessesView PDFCite

Research ArticleOpen accessIn the abstractComparison of Pre-Processing and Classification Techniques for Single-Trial and Multi-Trial P300-Based Brain Computer InterfacesChanan S. Syan, Randy E.S. HarnarinesinghThe P300 component of Event Related Brain Potentials (ERP) is commonly used in Brain Computer Interfaces (BCI) to translate the intentions of an individual into commands for external devices. The P300 response, however, resides in a signal environment of high background noise. Consequently, the main problem in developing a P300-based BCI lies in identifying the P300 response in the presence … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,570 accessesView PDFCite
