A modified concept of PCA to reduce the classification error using kernel SVM classifier[Full-Text ] Dr. Neeraj Bhargava, Abhishek Kumar, Devesh Kumar, MeenakshiThis paper focuses on the mathematical technique PCA with the drawback of its mixing of data pixel. We have extracted principal directions of the covariance ellipse as done in PCA, but we will not blindly take the Eigen vectors corresponding to k largest values. Instead, we transform the data vectors into the new n– dimensional (n is dimension of old input space) vector space spanned by the Eigen vectors of the covariance matrix of the input data and then take one attribute at a time to perform classification. Then, we choose attributes corresponding to k - largest accuracy measures this approach of Eigen vector selection shall prove to be more effective than the traditional one with the improved approach to the conventional method in which we have considered the feature vector corresponding to the k- minimum error in order to reduce the dimensionality. The work has been implemented on more than 545 images of men and women to give efficient consequences in context of advance approach of PCA.

Graph Theoretic Approach for Data Mining[Full-Text ] Sabiha Firdaus, Md. Mahbubur RahmanThe need for mining structured data was apparent to the research community and one such approach focused on the topological view of data structures. Since the graph has a generic topological structure and is one of the most thoroughly researched data structures in Computer Science and Discrete Mathematics, state of- the-art techniques in graph-based data mining (GDM) have had profound influence. GDM has tremendous utility because graph-structured data occur widely in practical fields like biology, chemistry, material science and communication networking. Graph-based data mining represents a collection of techniques for mining the relational aspects of data represented as a graph. Two major approaches to graph based data mining are frequent sub graph mining and graph-based relational learning. This article will focus on one particular approach embodied in the Subdue system, along with recent advances in graph-based supervised learning, graph-based hierarchical conceptual clustering, and graph-grammar induction. The need for mining structured data has increased rapidly. One of the best studied data structures in computer science and discrete mathematics are graphs. Graph based data mining has become quite popular in the last few years. This study introduces the theoretical basis of graph based data mining and surveys the state of the art of graph-based data mining. Brief descriptions of some representative approaches are provided as well.

Development of an Executable Model for the Nigerian Voting System using Hierarchical Timed Coloured Petri Nets[Full-Text ] Ganiyu R. A., Omidiora E. O., Okediran O. O., Alo O. O., Olaoluwa A. O.Voting systems are complex systems that involve activities that take place before, during and after election. The world over, automation of voting systems has attracted the attention of academia and industry because voting system is fundamental to the success of any democratic process. In this paper, Hierarchical Timed Coloured Petri Nets (HTCPN) formalism is explored to develop an executable model for the Re-Modified Open-Secret Ballot System (REMOBS) adopted in Nigerian 2015 general election. The developed HTCPN model for REMOBS is made up of two modules representing the Accreditation Process and the Voting Process. Each of the modules comprises two sub-modules (voting_station and voting_booth). These sub-modules are made up of another layer of sub-modules that abstract key activities while each sub module in this layer is made up of several transitions and places. Thus, the developed HTCPN model can be easily modified through its associated modules to suit any future modification in voting systems.

Management of Municipal Solid Waste in Gwanda Town[Full-Text ] Maligana Mathe and Anthony PhiriSolid waste disposal and management has been both an urban and rural challenge; however this paper focused on management of solid waste in an urban area. The rate at which solid waste was generated has been far higher than the capacity to responsibly manage the solid waste. Solid waste volumes have increased in urban areas due to growing population, concentration of industries, consumption of residents and inadequate finance and facilities to manage waste collection and disposal(NEMA 2007:276). There has been growing consensus that the immediate generators of waste need to join hands with the authorities in dealing with this problem that had far reaching environmental and human health impact. An urban environmental impact assessment was conducted with the view of solid waste generated, management and disposal. Methods of collecting the data that were used were; observation, interviews and questionnaires. The impact of solid waste was investigated and intervention strategies proposed. The findings were that there are factors that lead to lack of sound solid waste management and among those were the economic situation of the day, lack of proper and well managed infrastructure as well as the negative attitudes by residents towards the management of solid waste. The findings of the study showed that the levels of public participation in solid waste management in Gwanda town need to be improved for the good. The roles played by the public in solid waste management in Gwanda town need to be clearly spelt out. The public thoughts of how the solid waste was managed should be looked into and fresh ideas pulled together for better solid waste management in the future.

ERP Software Solution For Small And Mid-Sized Non-Governmental Organisations[Full-Text ] Sanjhal Sharma, Ajinkya DeoreEnterprise Resource Planning-ERP is a software solution for business and data integration that works on the policy of ‘All in One’. It phases real-time data analytics and adopts a set of best practices in any firm. The seminar shall discuss the growing importance of an ERP system for effective and efficient management. It emphasizes the need of an intelligent centralized system for Non-Governmental Organizations to establish seamless communication among these organizations and also between the common people and the volunteers. A lot of small NGOs work for various social causes but not all have adequate resources to help their cause. Thus a simple and cost effective ERP system can automate management of human resource, financial resource and also share required resources easily among the NGOs. It’s important to be motivated towards uplifting those who are considered ’less fortunate’. Individual progress is the foundation to a nation’s progress as a whole.The Seminar will also discuss about a few case studies that have taken suitable efforts in helping such nonprofit organizations. The implementation will demonstrate a small component of the ERP system intended to help with a centralized database of several NGO’s, their integrated information and draw comparisons between various aspects of social work in these organizations through the ‘a priori’ algorithm. Thus the seminar will broadly explain how business and technology put together can have a great impact in speeding up efforts even towards such Noble sectors.

Cloning and characterization of Beta tubulin gene promoter from Brassica rapa and its expression analysis[Full-Text ] Hira Mubeen, Aftab Bashir, Muhammad W.Shoaib, Shahid Raza, Naveed HussainIn the present study, we report the cloning and characterization of abundantly expressed Beta tubulin (BT) gene promoter from the dicot plant Brassica rapa. Isolation and characterization of useful promoters is routinely required for genetic manipulation of plants and is important in achieving controlled gene expression in transgenic plants. The major constraint regarding the utilization of commercially available promoters is the intellectual property right (IPR), therefore, discovery of efficient new promoters is important considering the IPR issues. The theme of this research was focused on stable transformation, using GUS expression cassette under selected Beta tubulin gene promoter sequence, in Nicotiana tabacum via Agrobacterium-mediated transformation and perform expression analysis via histochemical GUS assay. The selected BT promoter sequence was cloned in plant expression vector (pGA482). The expression cassette was constructed in a modified vector derived from pJIT166 (pGR1) that contains GUS with intron under 2X35S promoter followed by CaMV terminator. The selected GUS expression cassette was developed by replacing 2X 35S promoter in pGR1, with the selected BT promoter. Further, GUS expression cassette was verified through restriction analysis and PCR amplifications. The PCR positive tobacco transgenic for BT expression cassettes was obtained and stained to check the GUS expression levels. The results are presented along with the proposed utilization of the studied promoter.

WAVE EXCITING FORCE ON A FLOATING RECTANGULAR BARGE DUE TO SURFACE WAVES[Full-Text ] Purity M. Ngina, David O. Manyang and Kaguchwa John NjengaThe prediction of parameters in sea keeping, for example, body response, wave load, deck wetness, slamming, among others, are some of the most important aspects in ship design. Furthermore, peak loads created by cyclone winds and waves and fatigue loads generated by waves over the body are also important design consideration for offshore construction. Offshore platforms which is part of offshore construction have many uses including oil exploration and production, navigation, ship loading and unloading and to support bridges and causeways, where offshore oil drilling is one of the most visible and imperative application. The structures aforementioned must function properly and safely for a longer period although they are subject to harsh marine environment. Due to these visible applications this paper is aimed at addressing impulsive hydrodynamic forces that come about due to presence of a rectangular floating barge on the wave terrain. The panel method developed by Hess and Smith (1964) will be used together with the appropriate Greens functions to help in deriving the integral equations.

A Review on Scheduling Algorithms for Multicast Services over WiMAX Networks[Full-Text ] Dr. A. D. Usman, Dr. S. M Sani, Aliu, D.Transmission of multicast traffic (such as video, data and voice services over World Wide Interoperability for Micro Wave Access “WiMAX” aims to make multicast traffic available to users anywhere, anytime and on any device. The major challenges of transmitting wireless traffic over WiMAX network through convention multicast schemes are throughput fluctuation (Variations) among the subscribers within the network coverage, unfair distribution of network resources, delay, delay jitter and packet drop because they are placed in different locations from the Base Station. These inefficiencies are as a result of different fading and path losses in time-varying wireless channel experience by the Subscribers. Scheduling algorithms are mainly responsible for utilization of available resources that are obtained in the network in order to ensure the desire quality of service, among those scheduling algorithms are Round Robin, Max Rate, first in first out, Maximum Throughput, proportional fairness and weighted fair queuing etc. This paper surveys various scheduling algorithms for maximization of network throughput, fair distribution of resource, minimize packet loss and delay in WiMAX. Performances and limitations of some of the previous works are identified. Finally, future research directions to improve on some of the observed inefficiencies are discussed.
