Combustion characteristics of biomass fuel briquettes from onion peels and tamarind shells.

Abstract: Rising worldwide demand and consumption of fossil fuels have elevated wealth creation, improved undesirable impacts on climatic change from emission of greenhouse gases, and endangered communal health. In developing nations, biomass wastes, which include but are not limited to agricultural residues, are generated in huge quantities yearly. During the disposal of biomass, incomplete combustion causes people to get exposed to elevated indoor concentrations on health-damaging pollutants including particulate matter and carbon monoxide. Inefficient usage or disposed biomass wastes may cause toxic impacts on higher levels of pollution, the consequent degeneration of public health and ecological contamination. It is possible to convert these wastes into energy-efficient briquettes through densification. In this research work, the combustion characteristics were identified from biomass briquettes which were produced from Onion Peels (OP), Tamarind Shells (TS) and Cassava Starch. OP-TS were mixed sequentially and conversely with different proportions. From the total weight of biomass, 10% of cassava starch was added and briquettes were produced under 200 kN pressure from the compressed hydraulic system within the dwell time of 60 seconds. The proximate characteristics such as the presence of water content, amount of fixed carbon, ash and volatile matter were determined by using the standard procedures of the American Society for Testing and Materials (ASTM). The ultimate parameter, which is inclusive of Carbon (C), Hydrogen (H) and Oxygen (O) were diagnosed in all produced biomass briquettes and calorific values were identified for all the produced biomass briquettes as well. OP-TS have better fuel properties in comparison with pine, cotton stalk (CS), wood sawdust (WS), municipal solid waste (MSW) and cotton straw biomass briquettes (CSB). Therefore, the produced biomass briquettes could bring substantial environmental and socio-economic benefits to rural communities and are potentially worthy fuels derived from agricultural wastes.

Quality-of-service routing using path and power aware techniques in mobile ad hoc networks

Abstract: Mobile ad hoc network (MANET) is a collection of wireless mobile hosts dynamically forming a temporary network without the aid of any existing established infrastructure. Quality of service (QoS) is a set of service requirements that needs to be met by the network while transporting a packet stream from a source to its destination. QoS support MANETs is a challenging task due to the dynamic topology and limited resources. The main objective of this paper is to enhance the QoS routing for MANET using temporally ordered routing algorithm (TORA) with self-healing and optimized routing techniques (SHORT). SHORT improves routing optimality by monitoring routing paths continuously and redirecting the path whenever a shortcut path is available. In this paper, the performance comparison of TORA and TORA with SHORT has been analyzed using network simulator for various parameters. TORA with SHORT enhances performance of TORA in terms of throughput, packet loss, end-to-end delay, and energy.
