In the article has been chosen and simulated the dynamic characteristics of a fuel tank during longitudinal oscillations. In this study we shall proposed methods for determining the dynamic properties during longitudinal oscillations of fuel tanks for structurally similar models. The computation results enable to determine load in attachment points of fuel tank, and reduced masses of the liquid in the fuel tank for different natural oscillation frequencies. The calculations show that in a steady state condition in the absence of longitudinal accelerations, and small amplitudes of liquid oscillations, when we exclude temperature changes (adiabatic thermal insulation), the decrement of free oscillations obtained as a result of computations remains unchanged and is equal to 1.

Specific objective to discover some novel information from a set of documents initially retrieved in response to some query. Clustering sentences level text, effective use and update is still an open research issue, especially in domain of text mining. Since most existing system uses pattern belong to a single cluster. But here we can use patterns belongs to all cluster with different degree of membership. Since sentences of those documents we would expect at least one of the clusters to be closely related to the concepts described by the query term. This paper presents a Novel Fuzzy Clustering Algorithm that operates on relational input data (i.e. data in the form of square matrix of pair wise similarities between data objects).


Author Keywords:- Fuzzy relational clustering, natural language processing, graph centrality.

Imaging modalities exploiting the use of Compton scattering are currently under active investigation. However, despite many innovative contributions, this topic still poses a formidable mathematical and technical challenge. Due to the very particular nature of the Compton effect, the main problem consists of obtaining the reconstruction of the object electron density. Investigations on Compton scatter imaging for biological tissues, organs and the like have been performed and studied widely over the years. However in material sciences, in particular in non-destructive evaluation and control, this type of imaging procedure is just at its beginning. In this paper, we present a new scanning process which collects scattered radiation to reconstruct the internal electronic distribution of industrial materials. As an illustration, we shall look at one of the most widely used construction material: concrete and its variants in civil engineering. The Compton scattered radiation approach is particularly efficient in imaging steel frame and voids imbedded in bulk concrete objects. We present numerical simulation results to demonstrate the viability and performances of this imaging modality.

Aim: Iodine deficiency disorders (IDD) are one of the worldwide public health problems of today. IDD remains a public health problem in Albania. We have done this survey in the Southeast area of Albania, to determine the level of iodine in salt samples at the household level. Methods: For the determination of the iodine of the salt the children brought the samples at school. Samples of the salt collected in plastic glasses (about 20gr salt for each person) were analyzed in the Food Chemistry Laboratory of the Institute of Public Health (IPH). The iodine content of iodized salt samples is measured using a Standard iodometric titration prescribed by DeMaeyer, Lowenstein and Tilly (WHO, Geneva 1979). Iodine is liberated using sulfuric acid. The free iodine is titrated with sodium thyosulphate, using starch as an indicator. We have analyzed 508 samples of the iodized salt from them 240 are collected from the city and 268 samples from the village. Results and conclusions: The median of iodine concentration of the salt samples was 24.63 mg/kg. Iodine content was found to be adequate in 71.20 % of salt samples in total. There is a difference between the median concentration in the areas city (48 mg/kg) and the median concentration in the areas village (33.5 mg/kg). 22.8% of the samples in the city area is and 27.2% of the samples in the village area are non adequately iodized (>15 mg/kg). Our study showed that IDD-s is still an important public health problem in our country.

This paper, proposes an analysis and design of a high efficiency boost-inverter with bidirectional back-up battery storage in fuel cell. When low-voltage unregulated fuel cell (FC) output is conditioned to generate AC power, two stages are required: a boost stage and an inversion one. In this paper, the boost-inverter topology that achieves both boosting and inversion functions in a single-stage is used to develop an FC-based energy system which offers high conversion efficiency, low-cost and compactness. The proposed system incorporates additional battery-based energy storage and a DC-DC bi-directional converter to support instantaneous load changes. The output voltage of the boost-inverter is voltage-mode controlled and the DC-DC bidirectional converter is current-mode controlled. The load low frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the FC itself. Analysis, simulation results are presented to confirm the operational performance of the proposed system.

HVDC Light systems range from 3MW to about 1000MW transmission technology combining power converters and DC cables. The power converters are based on Voltage Source Converters (VSC) and Pulse Width Modulation (PWM) control. The use of series connection of power semiconductors such as IGBTs is fundamental to the development of the HVDC Light technology. HVDC Light is excellent for underground and under water power transmission. By use of HVDC Light power converters and cables, it is possible to overcome the technical difficulties to connect small loads and small scale generating units to the AC grid and to make the connection economical and environmentally friendly. This paper presents viability analysis of using HVDC Light technology for electrification of Mafia Ireland (Tanzania) from the national grid. In the paper the load demand forecast has been performed to estimate the load for the next 25 years at Mafia Island. HVDC Light model has been developed and simulated using MATLAB/Simulink software. The simulation results show that HVDC Light system performance is capable of delivering reliable and quality power when the Mafia Island is supplied by national grid using HVDC Light system. The benefits include more reliable power supply reduced environmental effects.

Steel has some important physical properties like the high strength per unit weight and ductility as compare to reinforced cement concrete structure. Due to high yield and ultimate strength member sizes comprising the structure are slender sections. Structural steel special moment frames often are used as part of the seismic force-resisting systems in buildings designed to resist seismic loads. Bracings are required to inhibit lateral buckling the members.

Recent years have witnessed considerable efforts in the development of nanotechnology for drug delivery as it offers a suitable means of delivering both low molecular weight drugs and macromolecules either by localized or targeted delivery (Panyam & Labhasetwar, 2012). Nanoparticle drug delivery enhances the delivery or uptake by target cells and reduces the toxicity of the free drug to non-target organs, thereby increasing the therapeutic index (Singh et al., 2009). Cytotoxicity of nanoparticles or their biodegradation products remains a major concern and improving biocompatibility is clearly a major concern for future research (Dhanya et al., 2012). The use of natural polymers makes it possible to obtain materials with many interesting properties, such as low toxicity, biocompatibility and biodegradability, thus allowing their use as carriers (Müller et al., 2011). in this paper study of Core Shell Nanopectin
