Research ArticleOpen accessEvery word in the titleDevelopment and Evaluation of a Low-Density Biomass Feeding System for Fluidized Bed GasifiersA. E. Ghaly, A. Ergudenler, S. Alsuhaibani, V. V. RamakrishnanFor efficient operation of a biomass gasifier, the biomass material must be fed continuously to the system. A feeding system for chopped straw and rice husk was designed, constructed and evaluated. It consisted of: a frame, a hopper, an auger, two agitators, a drive system and a power unit. Initial testing showed that wheat straw and rice husk, being highly … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 7 Nov 2013 · 8,039 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleECONOMIC AND PERFORMANCE EVALUATION OF STOCHASTIC MODEL ON A BASE TRANSCEIVER SYSTEM CONSIDERING VARIOUS OPERATIONAL MODES AND CATASTROPHIC FAILURESRajeev Kumar, Sunny KapoorIn this study a stochastic model for a Base Transceiver System (BTS) is proposed that consists of various hardware and software components. A Base Transceiver System (BTS) may undergoes four modes during its operation viz normal, congestion, down and failure mode. The hardware and software components may have various types of major and minor faults. The occurrence of a minor … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 22 Jul 2013 · 7,075 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Multiple Input Multiple Output (MIMO) System Capacity with Spatial CorrelationsT. Gunasekaran, K. R. Shankar KumarProblem statement: Today’s wireless technologies just won’t get us to the hyper connectivity of uninterrupted access from any mobile device with unlimited bandwidth at real-time speeds. This is due to the low data throughput and scarcity in spectrum. Approach: Under the condition of uncorrelated antenna elements, capacity of the Multiple Input Multiple Output (MIMO) system can be increased linearly with … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 8,108 accessesView PDFCite
