Paper Title:

Security Assurance Through Strategic Information Systems Planning

Abstract:  Strategic Information Systems Planning (SISP) and pertinent Information Security Policy (ISP) in organisations are largely inevitable in the contemporary business systems. Embedding information security policy within the organisation’s strategic information system planning is essential for the effectiveness of using information systems in modern systems in a secure environment. A survey of relevant literature on SISP and ISP in organisations’ processes reveals a close relationship between them and draws attention to how contradictions within this relationship may threaten as well. We explore the importance of embedding the ISP process within the SISP, and how these two issues are vital to organisations. It is further established the inevitable complementary role of these to ensure the effectiveness of contemporary information systems. The strategic planning information system makes certain that new systems are deployed in a way that maintains the strategic objectives of an organisation while the security policy provides a framework for verifying that systems are shaped and managed in a secure manner. Embedding ISP in SISP appears to increase progressively the security capability of an organisation, and hence, the deliverables from the SISP process may be more effective, efficient and hencefsystems came with huge complexities  beneficial to the organisation. Although organisations may face security glitches throughout the application and operational phase, they must try hard such an inevitable embedding to avoid certain catastrophic risks, assure business continuity and enhance overall productivity. Finally, a cyber sensitive audit and control based ISP Components-based framework is proposed for embedding ISP into SISP, right from instantiation

Paper Title:

Factors Influencing Implementation of Sustainable CSR Practices in the Energy Sector in Kenya: Case of Kenya Electricity Generating Company

Abstract:   In the last decade, the issue of sustainability has become very critical the world over for governments and business alike. This has seen an increased uptake of CSR activities by many organizations in the areas of environmental, social and economics as marked by increased expenditure in implementation of CSR programs in an effort to contribute to the sustainability agenda. However, most of the CSR programs adopted by organizations are not sustainable as they have weak integration to corporate strategies are faced by lack of project sustainability, financial sustainability, weak structures and systems and low visibility. Moreover, the companies also face threats from communities, complex regulatory framework and there being a mismatch between community needs and corporate objectives as most of the CSR projects are dictated by boardroom decisions. If a business is to have a deliberate positive and consistent impact on society, then its purpose and values should be shared by all those who may influence and be influenced, affect or get affected by its actions. This study therefore aimed at providing a predictive mechanism of the various influences of implementation of sustainable CSR practices in organizations through a case study approach of KenGen one of the key players in the energy sector of Kenya.  The findings of this study is that interventions to reduce the restraining effect of negative influences such as internal inhibitors that sap out the power of positive forces  on implementation of sustainable CSR practices. The paper therefore proposes management intervention measures such as development of measurement metrics that will help track performance and prioritization of CSR programs based on need and impact assessment to ensure improved livelihood of target beneficiaries.

Design of Compact Frequency Selective Surface (FSS) by Loading Slits and Slots

Abstract:    This paper deals with the theoretical investigation on a reduced sized Frequency Selective Surface (FSS). The FSS is designed by loading slit and slot into square patch. It has been observed, how the variation of the dimension of the slot and slit results in shifting of resonant frequency . Compared to conventional square patch FSS the designed FSS can provide reduction in resonant frequency resulting in size reduction up to 87% corresponding to resonant frequency of 2.44 GHz..Theoretical investigations have been done by Ansoft Designer® software.

Paper Title:

Optimal Number of Distributed Generators in Power System Network

Abstract:     The distribution generator (DG) may be defined as the small-scale power generation technology that provides electricity closer to customers. The positive impacts of DG are: voltage support, power loss reduction, support of ancillary services and improved reliability. The investigation is done to study the impact of multi-DGs on power losses using the line loss reduction index (LLRI). The study has been carried out on IEEE 14 bus system using Newton Raphson (NR) method for load flow analysis. The investigation is carried out with the insertion of DG at different locations and the minima point was found. The experiment was performed with different sizes of DGs in medium ranges. The analysis of the results show that simply by increasing the number of DGs in the system to reduce the losses is not beneficial all the time. Beside the optimal location and size of DG for the loss reduction in distribution system, number of DG is also a vital factor. In this work, it is concluded that the optimal number of DGs is very important parameter to reduce the losses. The study gives the optimal number of DGs that could be installed in the distribution system to have minimum line losses.

Paper Title:

Energy Management of Hybrid Vehicle using Artificial Intelligence for Optimal Fuel Efficiency

Abstract:      In general, hybrid systems can be commanded by splitting the required power between the electric machine and ICE to meet the specific needs like fuel consumption, efficiency, performance, and emissions. This power splitting scenario, which is the key point of hybridization, is in fact the control strategy or energy management of the hybrid automobile. Performance of the system, therefore, depends on the control strategy which needs to be robust (independent from uncertainties and always be stable) and reliable. Moreover, in order to improve the system, the control strategy should be adaptive to track the demand changes from the driver or drive cycle for optimization purposes. In order to fulfill these conditions, there is a need to develop an efficient control strategy, which can split power based on demands of the driver and driving conditions. Hence, for optimal energy management of PHEV, interpretation of driver command and driving situation is most important. In view of this, a fuzzy logic based strategy for interpretation of driver command is proposed in this paper.

Paper Title:

Impact of Data Mining on Telecommunication Company Revenues

Abstract: Rapid advancement of the technology has made the telecommunication sector very competitive. In order to keep up with the competition, telecommunication operators have to identify the exact needs of the customers and offer services in-line with customer needs. The aim of this research is to investigate the applicability of data mining in identifying customer needs and how it can be adapted to increase the revenue of telecommunication companies. The objectives of this study include an  investigation  into the relationship between data mining practices and customer behavior patterns, relationship between customer needs and products or services, relationship between new product design initiatives and revenue increases of the companies, the impact of data mining on the revenue of telecommunications companies, and the development of a data mining framework to improve the overall Average Revenue Per User (ARPU) levels in the industry in addition to the designing of a Business Intelligence (BI) tool to enhance decision making processes for improving the overall ARPU levels of the industry. Firstly, the conceptual model is developed based on the feedback of a sample of employees who hold positions in the telecommunications sector. This model has four main variables; data mining, customer behavior, product and increased revenue.  Secondly, a preliminary study was carried out to test the variables and to find out how data mining can be applied to identify customer needs and how companies can benefit from using data mining techniques in their businesses. Next, a Data Mining framework was developed to make sure that the expected results could be received from the data mining exercise in place.  Finally, a Business Intelligence tool was developed to validate the data mining framework. The preliminary study revealed a clear relationship between the variables of the conceptual framework. Furthermore, it was evident that data mining could lead to better business decisions, apart from the other key benefits of using it, such as timely delivery of services and an increase in customer satisfaction which may affect the revenue of the company. The post survey validation from the target users (managers of telecom companies) indicated that the proposed BI tool is capable of retrieving much needed information for business decisions, which would lead to increased revenues of the companies. The long term results are likely to be positive in this context and it is also evident that the role of data mining can be expanded by the companies and that this practice could eventually lead to companies providing markets with the exact requirements.

Mechanical and Metallurgical Effect on Tubular Shape by Laser Forming

Abstract: Mechanical properties of indirect hot stamping tubes are tailored by laser assisted partial rapid heating. A spiral heated region is generated on a rotating hot stamping steel tube by applying linearly moving laser. A microstructural analysis confirms that martensite phase transformation is occurred in the spiral heated region, thus inducing inhomogeneous microstructures along the length. Mechanical tests show that the mechanical performance of the indirect hot stamping tube can be tailored by properly selecting process parameters of the laser assisted heating. A microstructural analysis confirms that the laser locally induces a martensitic phase transformation in the heated region and results in inhomogeneous microstructures along the length of the tube

Application of Soft Computing Techniques to Predict Reservoir Water Level

Abstract:   In this work, the reservoir water level has been predicted using one of the soft computing techniques named Artificial Neural Network. The reservoir water level is influenced by many parameters. Among which the most influencing parameters have been considered here: amount of rainfall, temperature and evaporation. For this analysis, the reservoir made on Shetrunji River  Dam in Dhari, Amreli district, Gujarat, India has been chosen as it was overflown seven times in last ten years. This shows the importance of water level prediction at this particular reservoir. The Neural Network is trained using the past data collected and further used to predict water level for the unknown data. The approach of the multiple regression is also shown for its comparison with the Soft computing approach. Computations and experimental works were done by programming in software MATLAB. Such modeling is useful for planning and decision making of opening gates for reservoir operation particularly during monsoon and water scarcity.

Contemporary Approach for Graphical Password using CAPTCHA

Abstract:    Cyber security is an important issue to implement. Different types of user authentication methods are used to achieve this goal. It helps to avoid misuse or illegal use of highly sensitive and confidential data. Text and graphical passwords are mainly used for authentication functioning. But due to various pitfalls, they are erroneous for data security. Text passwords are un assured for reasons and graphical are tight secured in comparison but are sensitive to shoulder surfing attacks. Hence by using graphical password system and CAPTCHA technology a new security primitive is proposed. We call it as CAPTCHA as gRaphical Password (CaRP). CaRP is a combination of both a CAPTCHA and a graphical password scheme. In this paper we conduct a encyclopedic analysis of existing CaRP techniques namely ClickText, ClickAnimal and AnimalGrid. We discuss the advantages and disadvantages of each method and point out research direction in this area. We also try to answer “Are CaRP as secured as graphical passwords and text based passwords?” and “Is CaRP protective to relay attack?

Modified PI Controller to Improve the Performance Characteristics of the PMSM

Abstract:    Classical vector control for the permanent magnet synchronous motor (PMSM) is depending upon the mathematical model and hence any problem in the machine parameters or AC drives will deteriorate the performance of the drive system over all.  So this paper suggested using four PI current controllers to improve the performance characteristics of the drive system. Three of them is used in the bang-bang control of inverter by rate of one for each phase and the other PI current controller is used to improving the q-  axis current component at sudden applies or removes the load. this reflects the performance over all and improve it. The MATLAB Simulink is used to simulating the drive system. The proposed model of the vector control is compared to classical vector control to show the improvement occurs in the performance characteristics of the system with proposal method. The proposed cases are simulated through the MATLAB program and are operated in the laboratory. The laboratory results agreed with the simulating results that have been obtained
