The home automation needs to make use of latest and advance technology to makes it flexible, reliable and cost effective. Home automation involves introducing a degree of computerized or automatic control to certain electrical and electronics system in a building. The popularity of home automation has been increasing greatly in recent years due to much higher affordability and simplicity through smartphone and tablet connectivity. Most research aims to design and develop home automation system which is wireless and can be controlled via a multiple way to give more accessibility and control over a wide range of the systems. The main purpose is to develop and design an automation system which is accessible remotely to monitor and controlling it in a user-friendly way. Wireless communication in home automation systems is focused on low-power wireless communication modules. This paper proposes a cost-effective home automation system which is contains a combination of Android smart phone or tablet or a laptop and embedded system which include Arduino Due Board, Ethernet Shield module and Relay circuit. Also, most researches use an open source or a payed software to be used under Android media of the smart phones, but here the required interface Android pages are designed and implemented by researcher which reduce the cost of the proposed system effectively.

In Industries, it’s always look forward to reducing their operational cost and their Critical infra structures. Therefore, companies search for solutions to reduce their cost and ensure the system efficiency. One of that solutions is the use of a Cloud computing system which offers the advantage of integrating CPSs such as SCADA systems. This paper proposed a cost effective, simple, reliable and secured Cloud SCADA system. The proposed Cloud SCADA System based on secured nodes was implemented, which connects each other through VPN channel “encrypted’’ to ensure the isolation of our system form external attacks. The remote terminal unit (RTU) also connected to master terminal unit (MTU) through unit encrypted VPN channel, so in our system, when the end user need to connect to MTU the firewall of our system protect on MTU from un-recognized end point users. Comparing the cost of our system with pervious work, it’s lower than Arduino + WI-FI method by five times and 13 times lower than Raspberry-PI method. Also comparing with other server options the proposed server is easy for using, available for adding new components and also has high security.

The aim of this study is to assess the load modulation capability of a pilot plant open top downdraft gasifier using standard wood pellet. The input gasifying agent, which is air, can be split into primary air (from the top) and into secondary air, where the remaining required air is fed directly into the reduction zone of the reactor through a nozzle. The novelty of this research reside in the investigation of the effect of the supplied secondary air flow rate at different loads, with the aim to improve the load modulation capabilities by means of controlling the air distribution and achieving the higher possible conversion efficiency with varying amounts of producer gas power production. The gasifier was tested at different loads. The equivalence ratio (ER) is related to the mass flow rate of secondary air, thus by increasing the secondary air the equivalence ratio increases as well. The results confirm that it is possible to have high gas conversion at different loads using the mass flow rate of secondary air as a control parameter for the management of the equivalence ratio into the reactor., Proceedings of the 27th European Biomass Conference and Exhibition, 27-30 May 2019, Lisbon, Portugal, pp. 802-806

Gas-fired and coal based power generation plants result in the emission of CO2, a major greenhouse gas responsible for climate change. On an average, the flue from such power plants contain approximately 12– 17 vol.% CO2, 75 – 77 vol.% N2 and ~ 4.4 vol.% O2 with fractions of CO, NOx, H2 and SO2 in ppm range. While the capture and storage of this CO2 stream have been addressed actively in the literature, or even implemented rather unsustainably, its application in the fuel making process is imperceptibly addressed. This work examines the thermochemical biomass conversion with air and CO2 as gasification media to explore the possibilities and limitations of CO2 capture and its application in the fuel making process by the employment of the Boudouard reaction in the high temperature char zone to yield carbon monoxide. While this study revolves around the direct use of CO2 from the flue of diesel engines. The experimental investigations are based on the configuration of a downdraft reactor utilizing dried biomass pellets as feedstock. The mass flow rates of air and CO2 are measured and controlled using calibrated mass flow controllers and the biomass consumption rate is measured by placing the reactor over a digital weighing balance. A complete carbon balance is implemented in order to analyse the rate of formation of char under various conditions. This work demonstrates a mode of effective utilization of CO2 from the flue of exhaust gases in the power generation process that can even be integrated with a bio-refinery plant., Proceedings of the 26th European Biomass Conference and Exhibition, 14-17 May 2018, Copenhagen, Denmark, pp. 732-736

The present study investigates the conversion of producer gas from biomass gasification for the production of liquid biofuels through Fischer-Tropsch (FT) synthesis. Since FT synthesis is a catalytically driven reaction, the catalyst properties play a crucial role in determining the hydrocarbon yields and spectrum. In this regard, the current work investigates two catalyst synthesis methods, wet impregnation (WI) and combustion synthesis (CS). The CS method utilized herein employed lean stoichiometry with the cobalt nitrate-citric acid reaction. Three distinct alumina supported cobalt catalysts were tested: one was synthesized with the WI method and two with the CS method at two different equivalence ratios (.=0.6, .=0.3). All the catalysts were tested for approximately 70 h, after stabilization, at 230 °C, 30 bar, H2/CO=2.1 and 2000 mL h-1 g-1. All the catalysts exhibit conversions higher than 40% and hydrocarbons in the range C1-C35 could be detected. The best performance is achieved by CS(.=0.6) catalyst., Proceedings of the 27th European Biomass Conference and Exhibition, 27-30 May 2019, Lisbon, Portugal, pp. 1262-1265
