Wind turbines use the kinetic energy of the wind for generating the electricity by using ac generators. The generated electrical power is supplied to the grid. The produced energy mainly depends on the wind speed and the swept area of the turbine. As the wind speed increases accordingly the dimensions of the blades of wind turbine reduces. The blades are made auto adjustable with the help of stepper motor and control unit mounted on it. Various designing aspects are discussed while maintaining the generated power as 4.2kw. The wind turbine blades power and efficiency has been measured at different tip-speed-ratios and a maximum efficiency of 30% at 1.27 N/m3 air density. Present work gives an insight into the design aspects of a wind turbine, like turbine blade design, wind power and output power calculation. This paper presents an idea to maintain the generated power constant at variable wind speed by changing the blade dimensions. © 2014 IEEE.

Distributed real time database processing is still one of the most typical problems in high data computing. Complex systems have to execute millions of data accesses in each and every hours with hundreds of thousands process to executes some tens of millions of data information. This paper has focus on process with a large number of processing instances, or servers, respectively. In this paper, we proposed a dynamic Load balancing algorithm used in distributed database environment. Our basic thinking is to provide a considerable request response time and transaction per unit time instead of distributing the all workload among all servers equally. Next, new algorithm is designed and evaluated using analytical models. © 2015 IEEE.

A compact dual-band monopole patch antenna is designed for WiMAX and WLAN applications. The proposed antenna operates over two bands a lower band for WiMAX system (3.1–3.9 GHz) and higher band for WLAN system (IEEE 802.11a standard) with resonance at 3.46 and 5.48 GHz respectively. It consists of double C-slots on a rectangular patch which is directly fed by a 50 Ω microstrip line and a truncated ground with two slots cut in it. Wider bandwidth is achieved by cutting slots in the ground plane. The antenna presented is quite small with dimension of 10 × 15 × 0.8 mm3 and quite wide impedance bandwidth of 22.85 % at resonant frequency 3.46 GHz and 35.42 % at resonant frequency 5.48 GHz. To investigate the designed antenna, various parameters of the antenna are studied such as S-parameter, current distribution, VSWR and radiation pattern. © Springer India 2016.

The aim of this paper is to develop a method based on a combination of empirical mode decomposition (EMD) and discrete wavelet transform (DWT) for assessment of damage of the induction motor bearing. A machine in standard condition has certain vibration signatures. These signatures are modulated by a number of high frequency harmonic components resulting from structural response to individual impacts. Fault development changes that signature in such a way that can be related to the faults, and EMD is used to separate these intrinsic modes known as intrinsic mode functions (IMFs).Hilbert Transform (HT) is applied to first fourIMFs to get instantaneous amplitude and then applied power spectral density (PSD), to identify the related defect frequencies. Later, DWT has been applied to the IMF, which has higher amplitude and again fault frequencies are obtained from HT and PSD. The work evaluates the detection ability of theappliedmethods. The obtained results show that the proposed method is superior tothe traditional envelope spectrum methodof extracting the incipient faults of roller bearings. © Research India Publications.

The integration of Mobile Ad hoc Networks (MANETs) and the Internet is achieved by a gateway [13,15]. Several gateway discovery schemes/ approaches have been proposed that select gateway nodes based on certain Quality-of-Service (QoS) parameters such as path availability period, link capacity, end-to-end delay, etc. However, none of these schemes improves the overall network performance. To improve the overall network performance, it is necessary to select a gateway in such manner so that the path from source node to gateway should be lightly loaded, available bandwidth and residual energy should also be high. As MANET’s are energy constraint, the residual energy plays a vital role in determining the network lifetime. In this paper, we propose a gateway discovery scheme that considers multiple QoS path parameters such as load, bandwidth and residual energy of a path from source node to gateway. The mobility and residual energy of participating nodes in a route are unpredictable; however these unpredictable parameters cannot be analytically derived. Under these circumstances, we utilize the potential of fuzzy-logic system to estimate the stability of the routes. A route maintenance technique based on fuzzy logic mechanism is used to deal with the frequent disconnection of route either because of too less residual energy or due to mobility of nodes. The proposed approach is validated over the prototype model. Results shown are outperforming to existing approaches. © Research India Publications.
