A Macro-Micro manipulator is a complex plant with high nonlinearity, and the equations of motion of a Macro-micro manipulator have infinite dimensions. Hence, the control problems for a macro-micro manipulator are challenging tasks, seeking a control strategy which is independent of precise plant mathematical model is of practical meanings. In this paper a novel data-based fuzzy adaptive control strategy for a macro-micro manipulator is presented, and procedures for designing a fuzzy adaptive controller are described based on the collected experiment data. Good result is observed in the fuzzy adaptive control experiment of a macro-micro manipulator, the vibration suppression and precision positioning performance is achieved. © 2013 IEEE.

The Radio Frequency Identification (RFID) system is combination of a tag and reader. The RFID tag provides a cost effective solution to identify the object. The object may be any living and non living. The RFID system is used many applications such as healthcare, sales supply chain, luggage identification and security enabled keys, etc. These applications were discussed in various research papers, but till now, no one introduced the food safety centre enabled RFID system. That is the physical factors affecting the food to get into contaminated need to be identified and remedy need to be taken for the same. This RFID system needs to be integrated with the Wireless Sensor Network (WSN) Enabled Architecture. So this system is called as RFID Sensor. This research paper also presents three various methodologies to identify the physical affect that affecting the food. At the end of this paper, discuss about how the RFID Sensor is going to be introduce in the Food Safety Centre in Indian Ration Shops. © 2014 IEEE.

The inhibition efficiency (IE) of an aqueous extract of garlic in controlling corrosion of carbon steel in well water in the absence and presence of Zn 2 + has been evaluated by mass-loss method. The formulation consisting of 2 mL of garlic extract and 25 ppm Zn 2 + offers 70 inhibition efficiency to carbon steel immersed in well water. Polarization study reveals that this formulation controls the anodic reaction predominantly. FTIR spectra reveal that the protective film consists of Fe 2 + -allicin complex and Zn(OH) © 2013 K.

Third-order nonlinear optical properties of Mg doped CdS-PVP films have been studied by Z-scan technique with 5 ns pulses, mod-locked Nd-YAG laser with a frequency doubled at 532 nm. The nonlinear refractive indices and nonlinear absorption coefficients were in the order of 10-10 cm2/W and 10-3 cm/W and they are characterized with self-defocusing and saturable absorption behavior. The maximum third-order nonlinear optical susceptibility (χ3) and figure of merit are found to be about 1.432×10-4 esu and 8.558×10-9 esu m, respectively. The estimated χ3 is two to three orders of magnitude larger than that of the CdS film. © 2014 Elsevier B.V. All rights reserved.

Salem Chalk Hills, Tamil Nadu, India lies amidst the mineral rich geological formation. The region has been experiencing a lot of land use/land cover changes induced by both people and industries in recent years following the exploitation of different minerals. The overburden of mines when dumped in unmined areas creates mine spoils which ultimately affect the surrounding. This study sought to determine the rate of land cover changes that occurred in Salem Chalk Hills region since 2002. This was achieved through the use of satellite image of LANDSAT TM and IRS P6 LISS IV MX. Therefore, present study has been undertaken to analyze the process of humaninduced landscape transformation in the mine affected areas of Chalk Hills of Salem by interpreting temporal remote sensing data for the year 2002 and 2012 using GIS. Land use changes have been detected by image processing techniques. Field observation and measurements have also employed to validate results from remotely sensed data. Results show that the rate of land use/land cover change has been significant and it is due to mining activities. This accelerated change is mainly attributing to cultivation. It has been observed that there are significant changes especially in agricultural land and built-up area. During 2002 buildup land is 11.24 km2 and it is increased as 44.28 km2(11.60%) in 2012. The area of water body has been shrunk by about 0.38%. Changes in the agricultural lands are related to urban population growth of the study area. The expansion of build up lands and urban areas and contraction of agricultural land and water bodies leads to environmental degradation in the form of soil erosion. Similarly land with scrub decreased and land without scrub is increased.

In this paper, the prominent factors, which yield better weld bead geometry of the robotic GMAW joints, were optimized. Taguchi parametric design and optimization approach has been applied to determine the optimized level of input parameter composition. Arc current, stick out, arc voltage and travel speed are taken as input parameters to determine the bead width. The statistical technique ANOVA has been used to check its significance. The results show that the input parameters have significant effect on deciding the weld bead width. The results were confirmed by further experiments. © 2014 Praise Worthy Prize S.r.l. - All rights reserved.

In this paper we investigate the fuzzy optimization of electric vehicle (EV) and home energy scheduling. Our objective is to minimize the total electricity cost while considering user com-fort preference. We take both household occupancy and EV travel patterns into account. The novel contributions of this paper lie in the exploitation of EVs as dynamic storage facility as well as de-tailed modeling of user comfort preference, thermal dynamics, EV travel, and customer occupancy patterns in a concrete optimization framework. Extensive numerical results are presented to illustrate the efficacy of the proposed design. Specifically, we show that the proposed design can achieve significant saving in electricity cost, allow more flexibility in setting the tradeoff between cost and user comfort, and enable to reduce energy demand during peak hours. We also demonstrate the benefits of applying the proposed framework to a residential community compared to optimization of individual household separately. © Research India Publications.

The present paper describes experiences of the use of monitoring and data acquisition systems (DAS) and proposes a new concept of a low cost DAS applied to decentralized renewable energy (RE) plants with an WSN interface. The use of such systems contributes to disseminate these plants, recognizing in real time local energy resources, monitoring energy conversion efficiency and sending information concerning failures. These aspects are important, mainly for developing countries, where decentralized power plants based on renewable sources are in some cases the best option for supplying electricity to rural areas. Nevertheless, the cost of commercial DAS is still a barrier for a greater dissemination of such systems in developing countries. Most energy projections show that current and expected future global energy demand patterns are not sustainable. Long-term projections indicate that the world energy demand may increase dramatically, with most of this increase taking place in developing countries. For instance, according to projections made by the World Bank and the International Monetary Fund, Asia and South America are believed to present higher growth rates than the rest of the world within the next decade. © Research India Publications.

This paper proposes an isolated coupled-inductor integrated dc–dc converter with a voltage doubler for solar energy applications. The proposed converter realizes high step-up voltage gain without incurring a high coupled inductor turns ratio by adapting a dual-voltage doubler circuit. In addition, the energy in the coupled inductor leakage inductance can be recycled on the primary side. Thus, the system efficiency is improved. Finally, a laboratory prototype for demonstrating the performance of the proposed circuit is implemented with voltage doubler 12.5-V input voltage, and a 280-V output voltage. The experimental results show that the peak efficiency of the proposed converter is about 95%. © Research India Publications.
