Abstract: SrTiO3 and Sm3+: SrTiO3 ceramic powders were prepared by using a conventional solid state reaction method. The Structural, photoluminescence and dielectric properties have been studied for those ceramic powders. The XRD study reveals that the formation of mono phasic compounds and indicated structure to be changed from cubic to tetragonal by adding the samarium dopant. The Raman studies explain the structural phase transition and SEM with EDS explains the morphological and elemental analysis. From the SEM analysis reveals that the samarium doped strontium titanate grain size is increased compared to the pure strontium titanate. Under an excitation of 410 nm, corresponding to this transition is (6H5/2 ? 4L13/2) the emission wavelengths will be occurred. Among the all emission wavelengths, the 602 nm (4G5/2 ? 6H7/2) is a bright reddish orange emission wavelength. We also investigated the dielectric properties as a function of frequency in the range of (100Hz - 1MHz) at room temperature. For dielectric properties, the dielectric constant (er), tangent loss (tan d) and as well as AC conductivity were measured. These dielectric properties can be used in energy storage applications.

Abstract: In the present days the price and usage of petroleum products are increased more and more, due to this the search of alternative fuels has gain more importance in order to replace it. Coming to the diesel engines the best alternative fuel is Biodiesel, because it can be used directly without changing the engine modifications. Performance and emission characteristics of diesel engine were reviewed in this work. This study was conducted using biodiesel prepared from the raw oils of palm. Performance and exhaust emissions of diesel engine have been experimentally investigated with palm oil (P100) and its blend (P10, P20, P40, P60 and P80) with diesel fuel. Engine performance parameters namely break thermal efficiency, specific fuel consumption (SFC) and mechanical efficiency of CO, HC, CO2 and NOx were determined for different loading conditions and at constant engine speed of 1500 rpm. The test result indicates that there is a slight decrease in brake thermal efficiency and increase in specific fuel consumption for all the blended fuels when compared to that of diesel fuel with respect to increase in load. The drastic reduction in carbon monoxide and hydrocarbon were recorded for all the blended fuels as well as with neat biodiesel. However, in the case of oxides of nitrogen, there is a slight increase for all the blended fuels and with neat biodiesel when compared to diesel fuel with respect to increase in load. On the whole, Palm oil and its blends with diesel fuel can be used as an alternative fuel for diesel in direct diesel engines without any significant engine modification.

Keywords: Palm oil, Performance, Emission and Consumption.

Abstract: Multipliers are vital components of any processor or computing machine. Performance of microcontrollers and Digital signal processors are evaluated on the basis of number of multiplications performed in unit time.To enhance speed many modifications over the standard modified booth algorithm, Wallace tree methods for multiplier design have been made and several new techniques are being worked upon. Amongst these Vedic multipliers based on Vedic mathematics are presently under focus due to these being one of the fastest and low power multiplier. Hence better multiplier architectures are bound to increase the efficiency of the system. Vedic multiplier is one such promising solution and has better results. Its simple architecture coupled with increased speed forms an unparalleled combination for serving any complex multiplication computations. Tagged with these highlights, implementing this with reversible logic further reduces power dissipation. Power dissipation is another important constraint in an embedded system which cannot be neglected. In this project we bring out a Vedic multiplier known as "Urdhva Tiryakbhayam"meaning vertical and crosswise, implemented using reversible logic, which is the first of its kind. This multiplier may find applications in Fast Fourier Transforms (FFTs), and other applications of DSP like imaging, software defined radios, wireless communications.

Abstract: Recently, advances in intelligent mobile device and positioning techniques have fundamentally enhanced social networks, which allow users to share their experiences, reviews, ratings, photos, check-ins, etc. The geographical information located by smart phone bridges the gap between physical and digital worlds. Location data functions as the connection between user's physical behaviours and virtual social networks structured by the smart phone or web services. We refer to these social networks involving geographical information as location-based social networks (LBSNs). Such information brings opportunities and challenges for recommender systems to solve the cold start, scarcity problem of datasets and rating prediction. In this paper, we make full use of the mobile users' location sensitive characteristics to carry out rating predication. It is discovered that humans' rating behaviors are affected by geographical location significantly. Moreover, three factors: user-item geographical connection, user-user geographical connection, and interpersonal interest similarity, are fused into a unified rating prediction model. We conduct a series of experiments on a real social rating network dataset Yelp. Experimental results demonstrate that the proposed approach outperforms existing models.

Keywords: huge information, Geographical region, Social community offerings, score prediction, smart phones, user rating self perception.

Abstract: The present days wind energy is act as highest role in power industries and also different types of wind technologies are used in power industries depend on the application. Mostly wind based energy generating industries are using double fed induction generator (DFIG) because it is cable to work wide range of speed and frequency. DFIG is a wound rotor induction generator and it improves the electrical energy with rotor and stator plus circuits. Stator sends power directly to grid in unidirectional way. Rotor circuit is connecting to bidirectional converter (AC/DC/AC). The bidirectional converter means power flow in rotor to grid (or) grid to rotor. The main advantage of grid voltage converter is used to maintain constant DC link voltage. In this paper DFIG is controlled by using PI and FUZZY controllers. Finally DFIG is controlled effectively by using FUZZY controller compared to the PI controller with total harmonic distortion analysis (THD). These technologies are design by using software MATLAB/SIMULINK version 2012b.

Abstract: This paper focuses on the thermal analysis of the wells within the proximity of those used by previous geothermal demonstration project carried out at the University of Regina in 1977. In addition, wells around Moose Jaw within the deep clastic and carbonate rock units (between 2 km and 3 km); with focus on the Deadwood and Winnipeg formations were also investigated. The bottom-hole temperatures (BHT) of the target wells were extracted from the well database (IHS AccuMap and GeoScount) and corrected using the Harrison correction method. The thermal gradient for each well was obtained using the corrected BHT values, through which the subsurface temperature for each well (at depths 2.5 km and 3.0 km) was calculated using the Lachenbruch model. The paper presents findings of a conservative subsurface temperature range of approximately 50 ?-90 ? consistent at depths 2.5 km and 3.0 km. This range is certainly inadequate for electricity generation from the resource, though direct use applications can be pursued. A potential heat mining field is highlighted within the findings east of Regina as a potential area of interest for direct use applications (heating and cooling of buildings).

Abstract: Mesoscale parts are the parts whose two dimensions are in the range between 0.1 and 10 mm. Owing to the increasing demand on miniaturized devices or machines, requires the production of miniaturized pats. Mainly, mesoscale parts are utilized in electronic devices, aircraft industry, and defense industry. Because of small dimensions, conventional type of forming is difficult and can be expensive. In this study, meso/miniature forming with flexible die was investigated numerically and experimentally. Dome shape was studied for aluminum 1100 H14 sheet as a workpiece using polyurethane rubber as flexible material. The analyses were carried out for polyurethane rubber with two different hardness values (60A and 80A Shore) and for the conventional (metal to metal) forming process. Also, experiments were conducted to verify the finite element analysis (FEA) results. The results show that tearing in conventional forming was prevented by using flexible die. The process is applicable for forming of mesoscale parts without excessive thinning. Also, the harder polyurethane is better to get desired final geometry than the softer one.

Abstract: Characterization of source rocks is one of the most important goals in oil exploration. The lack of core samples in most of the drilled wells is a problem in characterising source and reservoir rocks. Many attempts are introduced to evaluate source rocks by using open-hole logging data. In the present study wire line logs (GR, RD, ROHB, PHIN and DT) are used to characterise the Upper Cretaceous source rocks in GPT oil field. Moreover, one dimension basin modelling analysis is applied to show the burial history and thermal maturation of the study area. Source rock analysis show that most of the studied units have considerable amount of hydrocarbons, but they are not potentially enough to produce indigenous oil, except for Abu Roash "F" Member which has enough potential hydrocarbons to produce indigenous oil and gas; this reflects the indigenous nature of the encountered hydrocarbons of this member. Burial history modelling of the study area show that Khoman Formation is immature, Abu Roash "D, E, F and G" members are early mature and Abu Roash "F" Member is immature in one of the study wells.

Keywords: Source rocks, wireline logs, total organic carbon, Basin modelling.

Abstract: Self compacting concrete is the latest development in the concrete technology for better durability, high deformability and fluidity for construction industries. In this paper, mechanical properties of self-compacting concrete (SCC) made with iron slag (IS) are investigated. The possibility of using it as partial replacement of fine aggregates in concrete mix is studied and evaluated based upon the percentage of the partial replacement of fine aggregate with iron slag. In this research work, iron slag obtained from industry is replaced with fine aggregate accordingly in the reach of 0, 0.1, 0.2, & 0.3 by weight of M25 grade of concrete. Various tests were done for fresh SCC properties, compressive strength and split tensile strength. The experimental results showed that the iron slag replacement with fine aggregate content gives better strength than control mixture of self compacting concrete and can be suitably used in self compacting concrete.

Keywords: self compacting concrete, fly ash, iron slag, compressive strength, split tensile strength.

Abstract: The paper contains glimpses of rather a brief review of Albert Einstein right from his childhood till his death. The subject matter of the paper is revised version of what the author delivered as a lecture on the 106th birth anniversary of the scientist to the faculty of an eminent institution in Mumbai, India. It is difficult to give only just glimpses of a great scientist like Albert Einstein. But, what I have presented in the paper with large number of diagrams, quotes and statements numbering more than 100 made by Einstein, the reader will find it to be exhaustive making it really a treatise rather than a simple treatment.

Abstract: This paper proposes to achieve an high step-down ratio by using MMC DC-DC converter topology and maintaining high conversion efficiency with high power rating. For High step down ratio dc-dc power conversion power electronics transformers are can be used. This arrangement requires a large number of high isolation voltage transformers and complicated balancing control. To overcome this drawback the solution is inherent voltage balancing, this paper introduces a new MMC topology for dc-dc conversion. Depending on the number of sub modules the MMC achieves high-voltage step-down ratio. With no necessary requirement of high-voltage isolation transformers the converter exhibits simplicity and scalability by using Digital switching, the converter operating frequency is high compared to the switching frequency. The operation principle and theoretical analysis are presented in this paper.

Abstract: The number of total coliforms is widely used as indicator of the presence of pathogens. They coexist in the human large intestine and even after disposal to the environment. One useful application is in the determination of the presence of coliforms in food, specially those to be consumed by the public without further heat treatment or cooking. Such is the case with ready to eat (RTE) salads. In this study, the vegetable jarjeer (Eruca sativa), rocket in English, was the vegetable tested. Jarjeer is usually a component of green salads and there were reports that these vegetables were harbouring coliforms which could not be removed by washing. It was therefore appropriate to test some household common disinfection method such as microwaving if it would be effective in inactivating these coliforms present in jarjeer. Both the time of inactivation and the thickness of the jarjeer placed in the plate were varied in the experiment. At a thickness of 0.1 cm and inactivation time of 15 seconds a 58% reduction in coliform was obtained and at 30 seconds inactivation time 81 % reduction was obtained. At a thickness of 1 cm, no reduction of coliforms was obtained at 15 and 30 seconds inactivation time. Note that the thickness of 0.1 cm was equivalent to the single leaf of vegetable placed on the plate so that it is already the minimum thickness possible for the study. A 58 or 81 % inactivation of coliforms is not acceptable as far as health safety is concerned since there are still plenty of coliforms left in the leaves. Ideally there should be few or no coliforms present (99.9 % inactivation). We therefore conclude that microwaving is not an effective method to inactivate the coliforms in jarjeer.

Keywords: coliforms, vegetable salads, pathogen, microwave, inactivation.

Abstract: This paper proposes an intersect mutation differential algorithm to solve the dynamic optimal power flow (DOPF) problem with the prohibited zones, valve-point effects, ramp rate and security constraints. The proposed method uses a novel direction to improve the global search ability of differential evolution algorithm. The dynamic optimal power flow problem is solved under multi-period conditions. Also, the prohibited zones, nonlinear characteristics of the alternative current power flow as well as technical constraints, such as transmission constraints, are all considered for the realistic operation. These features make the DOPF as a complicated nonlinear and non-convex optimization problem. This proposed intersect mutation differential evolution algorithm is applied for solving the DOPF problem on an IEEE 30-bus test system to illustrate the application of the proposed modeling framework. The results obtained on the IEEE 30-bus system are also compared with the results reported in the literature.

Keywords: Optimal power flow, dynamic optimal power flow, differential evolution; intersect mutation differential evolution, ramp rate constraint; prohibited zones. security constraints.

Abstract: This paper proposes the operation of doubly fed induction generator (DFIG) with an integrated active filter capabilities by using grid-side converter (GSC). The wind energy conversion system acts as a static compensator (STATCOM) for supplying harmonics even when the wind turbine is in shutdown condition. Compared to the multiple regression analysis neuro fuzzy logic showed higher accuracy in prediction for the five outputs studied. The important role in the grid side converter is supplying harmonics in addition to its slip power transfer. The rotor-side converter (RSC) is used for gaining maximum power extraction and also to supply required reactive power to the DFIG. Control algorithms of both GSC and RSC are presented in detail . Here we are using the neuro fuzzy controller compared to other controllers because of its accurate performance. The proposed DFIG- based WECS is simulated using MATLAB/Simulink.

Abstract: The efficiency of activated carbon of fresh water algae (FWA) a low cost adsorbent for removing Ni ions from aqueous solution and was evaluated by varying various parameters such as pH, contact time, FWA dose and initial Ni ion concentration. With increasing adsorbent dose and contact time the percentage of Ni removal increases. The percentage removal of Ni at low concentration (20mg/l) was found to be 84.17% in 120 min. for 1gm adsorbent dose. The percentage removal of Ni at high concentration (100mg/l) was found to be 86.70% in 120 min. for 1gm adsorbent dose. The percent removal of Ni at low concentration (20mg/l) and low contact time (30min) was found to be 45.35%. The percent removal of Ni at high concentration (100mg/l) and low contact time (30min) was found to be 48.50%. The maximum removal percentage of Ni at pH = 5 were found to be 84.25% for 100 mg/l at 120 min. The percentage removal of Ni at low adsorbent dose (0.2g) was found to be 57.29% for 100 mg/l at 120 min. The results revealed that the Nickel is considerably adsorbed on FWA and it could be an economically viable method for the removal of nickel ions from aqueous solution.

Abstract: CSP systems use direct solar radiation. There are two different systems point-focusing and line-focusing systems. Point-focusing systems (solar Paraboloid reflector and solar tower systems) need a two-axis tracking system, while line-focusing systems (parabolic trough and linear Fresnel systems) only require one-axis tracking. As the radiation intensity is the function of traveling length, many of research organization are working on how to reduce traveling length. In case of centre receiver system the focal is at greater distance than the solar parabolic trough system and the solar Paraboloid concentrator. The function of solar Paraboloid reflector is to concentrate diffused solar radiation at less focal distance. Heat is absorbed at receiver by conduction, convection to use it for various applications. The use of helical coil in evacuated receiver enhance heat transfer rate as compare to straight pipe because of greater surface area. Evacuated tube is generally used as receiver in parabolic trough concentrator to reduce convective and radiation heat loss from receiver tube.

Abstract: Wheel is a main mechanical term of the vehicular suspension system that supports the static and dynamic loads encountered during vehicle action. Since cars carry heavy loads of occupants as well as self-weight, the alloy wheel rim should be strong enough to withstand this load. Thus, their design should be done very cautiously. While designing such main kind of automotive component taking care of protection and cost are very important concerns so that user can use it safely. Major five technical considerations while modelling any new alloy wheel rim are styling, aesthetic, mass, manufacturability and capability. While analysing stress and displacement distribution in vehicle wheels subjected to increase pressure and radial load .essential efforts have been taken to discover the Finite Element Techniques. Alloy wheel rim has been designed using Creo software, after that static structural analysis is done with different materials, load and boundary conditions using ANSYS Software. At last the results of total deformation and equivalent stresses are obtained for different wheel rim materials and compared with each other. Thus, the best material can be selected for manufacturing of the wheel rim.
