Performance Analysis of Disaster Management Using WSN Technology

AbstractIn this research paper we propose a model of Wireless Sensor Networksused for pre-detection of disasters. Here we have discussed the basic architecture of WSNs and how these can be used in disaster management. The major reasons for mass destruction are Earthquake and Tsunami. Millions of lives are lost owing to these. Disaster, be it natural or man-made has a catastrophic impact on lives, money and infrastructure. We do not have a sensitive system yet which provides pre detection of these calamities. Therefore we need to take serious measures to ensure our safety from these disasters. WSNs are a new technology which can be helpful in these situations. The paper also throws light on the future scope of the topic. The information derived can be stored and used for future reference to predict climate of the area at a particular time period

Some Coupled coincidence and common fixed point theorems for hybrid pair of mappings

In this paper we extend the multi-valued mappings and obtain coupled coincidence points and common coupled fixed point theorems involving hybrid pair of single valued and multi-valued maps satisfying generalized contractive conditions in the frame work of a complete metric space. Keywords: coupled common fixed point, coupled coincidence point, coupled point of coincidence, w-compatible mappings, F-weakly commuting mappings

Effect of integrated nutrient management on growth and productivity of Withania somnifera (L.) Dunal in Kymore Plateau and Satpura hills of Madhya Pradesh, India

The field experiment was carried out at the Dusty Acres Farm, Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur, Madhya Pradesh to study the effect of integrated nutrient management for growth and yield of Withania somnifera (L.) Dunal (Variety: Jawahar Ashwagandha-134). Tallest plants (49.35 cm) were observed at harvest stage, whereas higher number of branches per plant (5.78) of W. somnifera was observed at 90 DAS with T11, respectively. The mean number of leaves per plant (125.40) and LAI (10.345) of W. somnifera was higher at 90 DAS with T11. Mean CGR was maximum (2.536 g m-2 week-1) and mean RGR was highest (0.098 gg-1 day-1) of W. somnifera at 90 DAS and thereafter decline at 120 DAS and harvest stage with T11. Whereas, mean dry matter (1392.60 kg/ha) production of W. somnifera was higher at harvesting stage of crop with T11. Significantly higher mean root length (16.30 cm), root girth (2.26 cm) and mean dry root yield (612.8 kg/ha) of W. somnifera was recorded under T11 than the rest of treatments. Mean number of berries per plant (30.78) and mean number of seeds per berry (194.17) of W. somnifera were significantly higher under T11. Higher mean seed yield (62.6 kg/ha) and harvest index (43.61%) of W. somnifera was observed under T11 as compared to other treatments. Therefore, 100% recommended dose of NPK through fertilizers along with vermicompost (2.5 t/ha), FYM (5.0 t/ha) and ZnSO4 20kg/ha (T11) followed by 50% recommended dose of NPK through fertilizers along with vermicompost (2.5 t/ha), FYM (5.0 t/ha) and ZnSO4 20kg/ha (T14) and 100% recommended dose of NPK through fertilizers along with vermicompost (2.5 t/ha) and ZnSO4 20kg/ha (T10) were found to be better integrated nutrient management for the cultivation of W. somnifera

Potentiality of Kolar Dam Water for Drinking Purposes

Kolar Dam, a major masonry dam, is located about 35 km away from Bhopal, near Lawakhari village in Sehore District. Constructed across the Kolar River, a tributary of Narmada on the right bank, the dam is about 45 m high. The maximum storage capacity is 270 Mcm. Kolar reservoir is the important sources of potable water supply for the Bhopal city. To assess its suitability for drinking purpose, the physico chemical and microbiological characteristics were studied on monthly basis.  In general almost all the parameters are within the range except coliform bacteria. Coliform bacteria were found beyond the norm prescribed for drinking water by various agencies. The analysis indicates that the water of Kolar reservoir is moderately soft with moderate alkalinity, transparent, low BOD, COD level as apparent by the study. The overall water quality of Kolar reservoir is not much affected by anthropogenic sources as it is surrounded by thick forest and less human activities are evident in this area. Therefore its water can only be used for drinking purposes but only after conventional treatment and disinfection. Keywords: Kolar Dam, Water quality, Physico chemical parameter, Drinking water

A Quantum Mechanical Model of Spherical Supermembranes

We present a quantum mechanical model of spherical supermembranes. Using superfields to represent the cartesian coordinates of the membrane, we are able to exactly determine its supersymmetric vacua. We find there are two classical vacua, one corresponding to an extended membrane and one corresponding to a point-like membrane. For the ${\mathcal N} = 2$ case, instanton effects then lift these vacua to massive states. For the ${\mathcal N} = 4$ case, there is no instanton tunneling, and the vacua remain massless. Similarities to spherical supermembranes as giant gravitons and in Matrix theory on pp-waves is discussed.Comment: 9 page

Exclusive light particle measurements for the system 19^{19}F + 12^{12}C at 96 MeV

Decay sequence of hot {31}^P nucleus has been investigated through exclusive light charged particle measurements in coincidence with individual evaporation residues using the reaction {19}^F (96 MeV) + {12}^C. Information on the sequential decay chain have been extracted by confronting the data with the predictions of the statistical model. It is observed from the present analysis that such exclusive light charged particle data may be used as a powerful tool to probe the decay sequence of the hot light compound systems.Comment: 13 pages, 8 figures, Physical Review C (in press

Geomagnetic storm dependence on the solar flare class

Content. Solar flares are often used as precursors of geomagnetic storms. In particular, Howard and Tappin (2005) recently published in A&A a dependence between X-ray class of solar flares and Ap and Dst indexes of geomagnetic storms which contradicts to early published results. Aims. We compare published results on flare-storm dependences and discuss possible sources of the discrepancy. Methods. We analyze following sources of difference: (1) different intervals of observations, (2) different statistics and (3) different methods of event identification and comparison. Results. Our analysis shows that magnitude of geomagnetic storms is likely to be independent on X-ray class of solar flares.Comment: 3 pages, 1 tabl

Dilepton Production at SPS-energy Heavy Ion Collisions

The production of dileptons is studied within a hadronic transport model. We investigate the sensitivity of the dilepton spectra to the initial configuration of the hadronic phase in a ultrarelativistic heavy ion collision. Possible in medium correction due to the modifications of pions and the pion form factor in a hadronic gas are discussed.Comment: Dedicated to Gerry Brown in honor of the 32nd celebration of his 39th birthday. 31 pages Latex including 13 eps-figures, uses psfig.sty and epsf.st
