Single Sensor Camera Image Denoising Using PCA and Demosaicking with LMMSE
Abstract: Single sensor cameras are used mostly for image acquisition in digital cameras with a colour filter array (CFA). These cameras save image in an unrefined format, since the complete process of image acquisition get lengthy and complex, so it introduces noise in the image and hence requires some efficient technique for denoising. Different techniques have been used to denoise the captured image but efficiency of the algorithms has not been …

Flooding Techniques in Wireless Sensor Networks: A Review
Abstract: Intended for network-wide dissemination of commands, configurations and code binaries, flooding has been investigated extensively in wireless networks. However, little work has yet been done on low-duty-cycle wireless sensor networks in which nodes stay asleep most of time and wake up asynchronously. In this type of network, a broadcasting packet is rarely received by multiple nodes simultaneously, a unique constraining feature that makes existing solutions unsuitable. Combined with unreliable links, …

Short Communication Defluidization Using High-Alkali Content Fuels in Fluidized Bed Biomass Gasifiers
Abstract: A major problem however often encountered in fluidized beds is bed agglomeration, which may result in total defluidization, leading to unscheduled downtime and additional costs. This problem is found to be critical in fluidized bed combustion and gasification of biomass fuels which have high ash and alkali contents [1]. Biomass fuels, especially herbaceous plants, often contain significant amounts of silicon, potassium and calcium, together with chlorine and sulphur. These elements …
