Effective and Secure vWSN Applications in a Virtualized Cloud Computing Environment

Security is one of the key concerns in cloud computing. We are proposing Virtual Wireless Sensor Network (vWSN) which is one of the key features of cloud computing in the area of agriculture. Our main focuses are effective and secure vWSN in virtualized cloud computing environment with enhanced security to detect environmental monitoring, humidity monitoring, soil moisture, air quality (pollution) monitoring, insect monitoring, pest and disease control, which is based on virtualization and cloud computing technology, centrally managed device having flexible and configurable parameter with less maintenance and operational cost. To the best of our knowledge, vWSN is the first approach to agriculture based on extensional WSN information. WSN contains both control plane (signaling) and data plane (forwarding) coupled together.WSN is a specific purpose computer containing hardware whose main components are memory, CPU, IO, registers, Data and address bus, timer, sensor, computing logic and decision making logic. WSN is a physical device which needs to be placed in the field in certain topology (Ring, mesh, tree, star) which may need to be protected for damage and erosion due to various parameter including but not limited to physical theft, damage due to weather, animal and various other reason. In this paper our approach is to propose virtualized model to replace physical wireless sensor network (WSN) to virtual machine (VM) based vWSN which can be deployed on the cloud. Since security is one of the major concern for VM in cloud computing therefore we also proposed the enhanced 3-tier security model for vWSN

Efficient Decimation of Polygonal Models Using Normal Field Deviation

A simple and robust greedy algorithm has been proposed for efficient and quality decimation of polygonal models. The performance of a simplification algorithm depends on how the local geometric deviation caused by a local decimation operation is measured. As normal field of a surface plays key role in its visual appearance, exploiting the local normal field deviation in a novel way, a new measure of geometric fidelity has been introduced. This measure has the potential to identify and preserve the salient features of a surface model automatically. The resulting algorithm is simple to implement, produces approximations of better quality and is efficient in running time. Subjective and objective comparisons validate the assertion. It is suitable for applications where the focus is better speed-quality trade-off, and simplification is used as a processing step in other algorithms

Supervised Machine Learning for Signals Having RRC Shaped Pulses

Classification performances of the supervised machine learning techniques such as support vector machines, neural networks and logistic regression are compared for modulation recognition purposes. The simple and robust features are used to distinguish continuous-phase FSK from QAM-PSK signals. Signals having root-raised-cosine shaped pulses are simulated in extreme noisy conditions having joint impurities of block fading, lack of symbol and sampling synchronization, carrier offset, and additive white Gaussian noise. The features are based on sample mean and sample variance of the imaginary part of the product of two consecutive complex signal values.Comment: 5 page

Genetic manipulation studies in Oreochromis niloticus L.

The results of a study aimed at the identification of treatment optima for triploidy induction in recently fertilised Oreochromis niloticus eggs by altering the intensity, duration and timing of application of pressure, heat and cold shocks are reported. Preliminary, but not directly comparable, trials suggested the following treatments to be close to the individual agent optima. Pressure; 8,000 p.s.i. 2 mins, duration applied 9 mins, after fertilisation (a.f.); heat: 41 *C, 3.5 mins, duration applied 5 mins. a.f.; cold: 9 *C. 30 mins, duration applied 7 mins. a-f. In a directly comparable trial in which the eggs of eight different females were separately exposed to the optimum shocks listed above, individual triploid yields were more variable following cold shocks and mean triploid yields were, therefore, higher following pressure and heat shock. The effects of triploidy on sexual development and maturation in female and male fish were examined in successive age groups (4 - 10 months). Significant differences in ovary weight and OSI were found between 3n and 2n females. But 3n males showed normal testis development and some of them could produce aneuploid sperm. The testis weight and OSI of such males were not significantly different compared to 2n. Comparative performance of growth, biochemical composition and endocrine profiles of normal diploids and pressure, heat and cold shocked triploids was investigated. 3n females were not significantly different in growth rate and proximate nutrition parameters compared to the 2n controls but were found to be functionally and endocrinologically sterile. 3n males showed no significant differences in growth or proximate nutrition parameters but were genetically sterile despite showing normal 2n endocrinological profiles and secondary sexual characteristics. Evidence is presented for successful suppression of first cleavage in O. niloticus and thereby the production of mitotic gynogenetics. The optimal parameters for UV irradiation of milt were 300 - 310 pW/cm> for 2 min at 4-C. The optimal pressure shock W.S 9000 p.s.i. for 2 mins at 28 *C at 40 - SO mins a.f. and that for heat was 41 *C for 3.5 mins at 27.5 - 30 mins. a.f. Isozyme analysis of putative mitotic gynogenetic survivors at ADA' locus confirmed homozygosity, therefore, restoration of diploidy occurred by inhibition of first mitosis. Subsequently gene-centromere recombination frequency estimated at six enzyme loci further revealed no recombination between the respective gene and centromere at all the loci. In contrast, recombination frequency in meiotic gynogenetic progeny was 0 - 100* (mean y = 0.41) which suggesting that this probably a reflection of the relative position of the various loci to centromere on their respective chromosomes. Production of heterozygous clones of O. niloticm was successfully carried out by crossbreeding between viable mitotic gynogenetic female and male sibs. At the same time, homozygous clones of the fish was produced by gynogenetic reproduction (retention of 2nd polar body) using optimal pressure/heat shock treatments. The outbred (OCL) and inbred (ICL) nature of two types of clonal lines were checked and identified at ADA' marker locus. A model for the large scale production of such clonal lines is presented. The effect of inbreeding on various phenotypic characters of two types of gynogenetics (meiotic and mitotic) in comparison to full sib controls was investigated. The coefficient of variation values of growth, meristic and all reproductive train were lowest in control, intermediate in meiotic and highest in mitotic gynogenetic group. This study revealed that the expansion of variation in such performance train in both type of gynogenetics was possibly the result of phenotypic expression of unmasked homozygous recessive and deleterious genes due to increasing levels of homozygosity (F value). Mendelian mode of ted body colour inheritance was studied in Egyptian red O. niloOcus and Thai ted tilapia attains. Cross-breeding between ted a ted and ted x wild parents resulted in mostly all red coloured progenies and in some red x wild crosses progenies were also segregated into red and wild types. The F. red hybrids mated infer se and back-crossed to wild type, the progeny phenotype segregated closely into approximating the expected 3 red: 1 wild and 1 red : 1 wild ratios respectively. These results demonstrate that red body colour in two mutant attains of tilapia is controlled by a single autosomal dominant "R" gene. But both the red strains contain differing proportion of heterozygotes (Rr). In order to produce pure breeding strains, it will be important to identify heterozygotes so that the “r" gene can be culled in some way. In this case. Mendelian test-cross technique has been proposed on the light of the present study as a means of probable solution. The possible implications of above results of genetic manipulation study in the aquaculture of Oreochromis spp. are discussed

Within the different types of organisational structures available, it is generally believed that co-operative organisations serve the poor better than the other available alternatives. This belief is based on the fact that these organisations are usually owned and controlled by the people and their objective is to provide services instead of making profits. They are, therefore, considered an important instrument for equitable development, and have been given a prominent role in the national development strategies in many developing countries. It is surprising, however, that the performance of cooperatives is not as satisfactory as it could have been. They have met with only occasional success in Asia. This book explores the causes of this failure

Micro Hydro Power: A Source of Sustainable Energy in Rural Communities: Economic and Environmental Perspectives

Energy is an important need of human life. It is the life blood of all economic activities. Due to increase in population and economic activities, the need for energy is increasing at a faster rate. Without having sufficient energy, the goal of economic and social development and the Millennium Development Goals in particular cannot be achieved. Most of the rural areas in different parts of the world are without electricity. About 1.6 billion people in the world who are living in rural areas are without electricity [Greenstone (2014)]. The reason is that it is too costly to provide electricity services to rural communities through conventional means due to remote location and low density of population. Moreover, due to poverty and low income the rural inhabitants are not in a position to afford the main grid electricity. The use of diesel and gasoline has been used for decades for provision of electricity to rural areas. But it was not so successful due to economic, technical and environmental problems [Woodruff (2007a)]
