Researches on the Photovoltaic (PV) generation are extensively increasing, since it is considered as an essentially indefatigable and broadly available energy resources. Hence, the role of distributed generation i.e. solar energy based generation is increasingly being recognized as a supplement and an alternative to large conventional central power supply but mostly in off-grid areas rather than cities, whereas centralized economic system that solely depends on cities is hampered due to frequent energy deficiency. To extenuate these problems, this paper proposes an optimized design of single phase grid-tied PV system without storage which is employed with transformer-less power circuits. Most precisely …


Performance Analysis And Comparison Of Wireless Protocols Standards In Wpan-Bluetooth And Wlan-Wi-Fi, Innovative Research Publications Irp India, Dr. P. Rajamohan, Mr. R. Thinaharan, Dr. Leela Vathi Dec 2014

Performance Analysis And Comparison Of Wireless Protocols Standards In Wpan-Bluetooth And Wlan-Wi-Fi, Innovative Research Publications Irp India, Dr. P. Rajamohan, Mr. R. Thinaharan, Dr. Leela Vathi

Innovative Research Publications IRP India

Communication is going wireless with the upsurge of smart mobile devices such as laptops, cellular phones, PDA, tablets etc. In order escape traps of wires and to stream data wirelessly among these devices, a number of protocols have been formulated such WPAN-Bluetooth and WLANWi-Fi. Using these technologies users can exchange almost all sorts of files at high speeds. Bluetooth is oriented to connecting close devices serving as a substitute for cables while Wi-Fi is oriented towards computer to computer connections, as an extension of or substitution for cabled LANs. This paper presents the performance analysis and comparison of all of …


Determination Of Some Physical Properties Of Castor (Ricirus Communis) Oil, Innovative Research Publications Irp India, Odesanya Kazeem, Olasheu Taiwo, Adebiyi Kazeem, Durowoju Mondiu Nov 2014

Determination Of Some Physical Properties Of Castor (Ricirus Communis) Oil, Innovative Research Publications Irp India, Odesanya Kazeem, Olasheu Taiwo, Adebiyi Kazeem, Durowoju Mondiu

Innovative Research Publications IRP India

The energy crisis and shortage of fuel emanating from total dependence on mineral oil with resultant socioeconomic problems demand the need to explore the use of renewable energy as alternative. This study evaluates the physical properties of the castor (Ricirus communis) oil. A quantity of 35 kg dried base decorticated seeds of castor was locally obtained, volume of 5 litres of castor oil was extracted from the seeds using existing hydraulic press machine, while its physical properties was determined through laboratory analytical procedure of American Society for Testing and Materials analytical standard 960-52 (ASTM,D960-52). The properties determined were: viscosity, density, …


Synchro-Phasors In Power System, Innovative Research Publications Irp India Aug 2013

Synchro-Phasors In Power System, Innovative Research Publications Irp India

Innovative Research Publications IRP India

The Phasor Measurement Unit (PMU) is considered to be one of the most important measuring devices in the future of power system. The difference comes from its unique ability to provide synchronized phasor measurements of voltages and currents from widely dispersed locations in an electric power grid called synchrophasor technology .In SCADA system, the measured quantities remain constant during the data gathering process. Hence the dynamic characteristics of the power system cannot be estimated. Synchrophasor technology is used to overcome this drawback. The Global Positioning Satellite(GPS) is used for synchronisation between the PMUs at different places, which receive the signal …


Autocad Programming For Reinforced Concrete Structural Detailing, Innovative Research Publications Irp India, Akilu Muhammad, Ibrahim Ogiri Hassan Mar 215

Autocad Programming For Reinforced Concrete Structural Detailing, Innovative Research Publications Irp India, Akilu Muhammad, Ibrahim Ogiri Hassan

Innovative Research Publications IRP India

AutoCAD, the popular software for Architectural and Engineering design is increasingly used today to achieve and speed and accuracy in work execution. Complex and repetitive drawings are automated through AutoCAD programming to optimise the design process. In this research, AutoLISP (AutoCad language), is used to programme AutoCAD for automated reinforced concrete structural detailing. Reinforced concrete Open-well staircase is used as a case study. AutoLISP customization features are used to define the coordinates of any point the software uses to draw any element in the detailing. AutoLISP functions were used in defining function of routines, obtaining user input, defining the drawing …
