Note on the Four Components of the Generalized Lorentz Group O(n; 1)[ ]


In physics and mathematics, the generalized Lorentz group is the group of all Lorentz transformations of generalized Minkowski space-time Rn+1. The Lorentz group is named for the Dutch physicist Hendrik Lorentz. The mathematical form of the kinematical laws of special relativity, Maxwell?s ?eld equations in the theory of electro-magnetism, the Dirac equation in the theory of the electron, are each invariant under the Lorentz transformations.

An Energy Efficient Dynamic Connected Dominating Set With Multi Point Relay For Wireless Mesh Network[ ]


A wireless mesh network is a collection of mobile nodes that can be deployed without the need for centralized management infrastucture.The operation of wireless mesh networks depends on the co-operation among nodes to provide connectivity and communication routes. However, these situations may not always be achievable in practice. Some nodes may result in degradation of the performance and high energy consumption. To mitigate the effect of such nodes and to save the energy level on the network, this paper expands on neuro fuzzy logic concepts to propose an algorithm used for quickly to data transmit and identify the nearby nodes on the source node. To take energy efficient based data transmission on their network using the dynamic connected dominating set with multi point relay. Compare the energy level with existing model by using simulation results. Using NS-2 simulator, the proposed algorithm is validated and further studied. The findings show that the proposed algorithm has low level energy consumption on the network.

A Survey on the Use of Nigeria Local Palm Oil for the Production of Polyol for Polyurethane Foam Production in Nigeria[ ]


This paper reviews the use of Nigeria Local palm oil for the production of polyol for the production of polyurethane foam in Nigeria. In the sub Saharan Africa and in Nigeria in particular, the market for polyurethane products such as rigid and flexible foam is so extensive owing to their vast applications. Currently, the polyol for polyurethane production in Nigeria is petroleum based and it is also being imported. Enormous resources are expended on this importation. Besides, petroleum is a depleting resource and cannot be banked upon. Nigeria is one of the top producers of palm oil and studies have shown that polyol could be synthesized from this palm oil. Polyurethane consumption in Nigeria is very high of which polyol constitute more than 50% of the formulation needed for the production of polyurethane. Polyol is not produced in Nigeria for now. Palm oil being a major source of this polyol and is abundant in the country, if appropriate technology is applied to harness this palm oil for polyol for polyurethane production in Nigeria ,it will bring about job creation, employment of new graduates which will stem the brain drain in the nation. If the resulting product is cost effective, commercializable and the production sustainable, our economy will be highly stimulated and there will be a world market creation.

Review on thermal challenges in embedded system[ ]


Embedded systems are used in safety critical areas such as automotive electronics and medical applications. These safety critical applications impose strict requirements on reliability, performance, low power and testability of the underlying VLSI circuits. The VLSI circuits operate very often at high temperature, which has negative impact on reliability, performance, power-efficiency and testability with silicon technology scaling. Several thermal impacts on VLSI circuits and their related challenges are discussed. This paper presents also a few emerging techniques that take temperature into account in the design and test processes. There are number of embedded computers controlling virtually all devices and systems in a huge spectrum of application areas including aerospace, manufacturing, chemical processes, healthcare care, automotive, transportation, telecommunication, and consumer appliances. Many of these systems are safety-critical, such as automotive electronics and medical equipment, with stringent reliability and real time requirements. At the same time, with silicon technology scaling, VLSI circuits used to implement the computational components of these systems are built with smaller transistors, operate at higher clock frequency, run at lower voltage levels, and operate very often at higher temperature. Consequently, they are subject to more faults and interferences.

Strategies for controling the spread of Hepatitis B virus in adult population[ ]


Hepatitis B virus (HBV) disease continues to spread among the adult population, though the disease is gradually driven towards eradication among infants and children due to vaccination. We present a deterministic model for controlling the spread of HBV among the adult population using adult catch-up vaccination and change in sexual habits as control measures. Using Senegal demographic data, we compute the disease prevalence for di erent combinations of levels of the two measures. We also compute the associated cost suggesting, under budget limitation, how to choose optimal intervention strategy.

Mathematics has an age-old relationship with physics and other natural sciences. It is the foundation of science and technology and the functional role of mathematics to science and technology is multifarious, that no area of science, technology and business enterprise escapes its application. This study interrelate the performance of students’ in mathematics and physics in senior secondary schools. The paper highlighted two pertinent points; first to determine the relationship between mathematics and physics, and second is to see whether success in mathematics can be used to predict success in physics and visa-visa. One null hypothesis was formulated to guide the study. Research data were extracted from 2009, 2010, 2011 and 2012 WAEC examination results from three secondary schools in Birnin Kebbi local government area of Kebbi state. The study adopted a descriptive survey design that employs simple linear correlation regression analysis in order to test the null hypothesis. The R values of 0.384, 0.104, 0.022 and 0.158 for the year 2009, 2010, 2011 and 2012 respectively indicated moderate to weak correlation. A test of significance, F-ratio was applied to the results. Since the calculated values of F were less than the critical values of F (F=1.62) at 5% level of significant, the null hypothesis was accepted. The result of the study therefore showed no significant correlation between students’ performance in physics and their performance in mathematics.

Big Data and Big Data Scrutiny with Hadoop’s MapReduce[ ]


Big Data is highly related to large-volume of data, complex with evolving relationship, growing data sets with multiple, heterogeneous and self-governing sources. There is a faster development of networking along with data storage and collection capacity. The data is said as "Big Data" due to its characteristics of Volume, Variety, Velocity and Veracity. Most of this Big Data is unstructured, semi structured and heterogeneous in nature. The volume and the heterogeneity of Big Data, with the speed it is generated, make it difficult for the present computing infrastructure to manage Big Data. Because of this nature of Big Data, traditional data management, warehousing and analysis systems are not satisfactorily able to analyze this data. In order to process Big Data, HACE Theorem is considered that characterizes the features of Big Data for Big Data Processing. Hadoop and HDFS by Apache is a software framework which is widely used for storing, managing and analyzing Big Data which is a challenging task as it involves large distributed file systems which should be fault tolerant, flexible and scalable. Hadoop’s MapReduce is widely being used for the efficient processing of large data sets on clusters which is nothing but Big Data. In this paper, the various solutions are introduced in hand through Map Reduce framework over Hadoop Distributed File System (HDFS). Map Reduce is a Minimization technique which makes use of file indexing with mapping, sorting, shuffling and finally reducing. Map Reduce techniques have been introduced which is implemented for Big Data analysis using HDFS.
