Analysis of Noise Pollution in Selected Areas of Ota, Nigeria[ ]


The physiological effects of noise pollution are alarming. Its visible effect on hearing damage, cardiovascular, childhood hypertension and hormonal disturbances are evident in developing communities. Six locations were selected in Ota, Nigeria. Data set obtained from the digital sound level meter was used to model the noise climate and the equivalent continuous noise level. While the noise climate of the mini-market was predictive in nature, the noise climate in the secondary school was very high and not predictive.

Natural Approach towards Mitigating Noise Pollution: A Case Study of Covenant University[ ]


The study of science has out-grown mere speculation. Scientifical procedure was adopted to verify if trees should be planted close to the noise source rather than the area to be protected. Six locations were selected in Ota, Nigeria. Data set obtained from the digital sound level meter was used to model the noise levels. The first location, the power generator behind the university chapel had trees around and the overall noise reduction was 12.5dB. The overall noise reduction in the second location was 47.12dB. Reduction from other locations was between 16dB to 25dB. Hence, if wind dynamics is excluded, trees should be planted close to the noise source rather than the area to be protected.

MULTI MODEL DYNAMIC WEB CRAWLER WITH HIERARCHICAL SUBSPACE CLUSTERING FOR EFFICIENT WEB SEARCH USING T2S PAGE RANKING[ ]


Designing web crawler to meet the web user requirement is most important where the user interest changes every day and they look for the most precise information at rapid time. There are many designs has been discussed earlier but suffers with the problem of generating précised and relevant result in rapid time. The problem of time complexity and accuracy is based on the indexing approach being used; in this paper a novel multi model dynamic web crawling model is discussed to improve the efficiency of web search. The paper discusses about three different models of similarity indexing namely topical, semantic, and taxonomical. With the computed different similarity measures, the document or the web page is identified as belongs to a class and the method extends the level of indexing into infinitive by performing hierarchical cluster. The method identifies the subspace of any web document in the cluster, based on the above computed similarity measure at each level. The pages of results generated is re-ranked using T2S (Topical-Taxonomical Semantic) similarity measure. The proposed multi model approach produces efficient results in web search and reduces the time complexity and increases the relevancy of results.

A COMPARATIVE ANALYSIS OF MOISTURE CONTENT VARIATION ON FLOW AND MECHANICAL PROPERTIES OF BREADFRUIT SEED (ARTOCARPUS ALTILIS)[ ]


Determination of some engineering properties of two varieties of breadfruit seed was carried out using standard procedures. The initial moisture content was 6.85% and later adjusted by rewetting to 14.85%, 21.85% and 28.85 %(wb). Angle of repose and coefficient of friction of the two varieties were also determined on three surfaces (plywood, glass and Aluminium). The mechanical properties at compressive yield were determined using universal testing machine. Data obtained were statistically analyzed using Minitab statistical software. Results showed var. Africana values are in the following ranges: angle of repose plywood (20.84 to 33120) on glass (17.04 to 29.560) and on aluminum (16.57 to 29.060). Coefficient of friction on plywood was (0.376 to 0.496), on glass (0.325 to 0.450) and on aluminum (0.368 to 0.469). While var. inversa have the following values for angle of repose plywood (17.04 to 22.970) on glass (20.38 to 30.07) and on aluminium (20.50 to 29.32). Coefficient of friction on plywood was (0.344 to 0.459), on glass (0.279 to 0.396), and on aluminium (0.348 to 0.433). These properties increased with increase in moisture content. The fracture resistance of var. africana and var. inversa were found to decrease with increase in moisture content. The data obtained from this study will aid in the design and construction of breadfruit seed threshing machine.

Statistical Analysis of Traffic Accidents Locations Using Geographic Information System in Darbandikhan Town- Kurdistan Region of Iraq[ ]


Road traffic accidents are a major cause of premature death and disabilities. Every year the lives of almost 1.24 million people are cut short as a result of a road traffic crash. Between 20 to 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. These losses arise from the cost of treatment (including rehabilitation and incident investigation) as well as reduced/lost productivity (e.g. in wages) for those killed or disabled by their injuries, and for family member who need to take time off work to care for the injured. The aim of the traffic accident analysis to investigate the cause accidents, to determine hazardous locations and to determine to enhance road features, to evaluate traffic safety after enhancement. This kind of system often includes a database query tool to store and analysis information about accidents mainly to identify high crash locations, in other words hazardous locations along the road.

A REVIEW ON SCHEDULING ALGORITHMS FOR RESOURCE MANAGEMENT IN DATA GRIDS[ ]


A very promising attractive computing model is Grid Computing. To provide high performance computing, grids aims to combine the geographically distributed, power of heterogeneous, multiple domain spanning computational resources. An efficient and effective scheduling system is important for achieving the capable potentials of grids. In grid environment, scheduling systems do not work for traditional distributed environments due to classes of environments which are completely dissimilar. Over various domains, making scheduling decisions involving resources is the process known as Grid Resource Scheduling. Across the management, grid scheduling must manipulate large-scale resources so there is high complication involved in it than the local resource scheduling. In this survey, discussion are made on grid scheduling algorithm with a view from different points which are objective function, QoS constraints, static vs. dynamic, strategies dealing with dynamic behavior of resources, application models, adaption and so on. This survey mainly focused a review of the subject from scheduling algorithm viewpoint rather than covering the entire grid scheduling area.

MULTI-SAMPLE ADAPTIVE TEST AND OTHER COMPETITATORS IN LOCATION PROBLEM[ ]


If the parametric assumptions are fulfilled, classical F test is the appropriate test for the multi sample location problem. On the other hand, if assumptions not satisfies ,F-test is not a suitable tests. So we have to search for some other tests. Test based on ranks or scores are found to be more powerful and robust in many situations. It is seen that many of the practicing statisticians have no idea regarding the data type. In this situations, the adaptive tests based on Hogg’s concept , may help the statistician to identify data type with respect to some measures like skewness and tail weight and then to select an appropriate rank test or test based on scores for classified type of distribution. In this chapter, we have first discussed the adaptive test procedure that are used to select an appropriate test and then compare an adaptive test and some of the tests procedure s with the help of Monte Carlo simulation technique. Both empirical level and power of these tests are calculated and comparison are made with F-test and different other adaptive tests. We have observed that adaptive tests behave well in broad class of distributions.
