Volume 4 ~ Issue 6

This paper presents investigation on generator availability and performance studies on four gas and six steam turbine unit generators at Sapele Power Station in Nigeria. The availability investigation covers from 2005 to 2011 and was done through an exhaustive collection of data from samples of operating facilities in the power station. Data was collected from plant user maintenance log, operation records and manufacturers‟ data were also sources of information. This investigation used the IEEE std 762 generator performance indices amongst other calculated key operational availability indices in the evaluations and analysis of the collected data. A software program was developed, "Function Outage Parameters (FOP)‟, using the outage frameworks of data collected from the station. The program was implemented in MATLAB 11.5b. The data was used to evaluate six (6) out of the ten generating units available in the station because four of the units (mainly gas turbines) had been out of service before the start–to–end period of investigation. The result was used to appraise performance indices and parameters and a periodic availability assessment of all the installed generating units.

Background: Pregnant women come to health care (provider)not only to get service, but they alsocome as they have needs and expectations, as well as to utilize antenatal care by health workers. Only 66% of pregnant women utilize antenatal care and the number declines during childbirth. Affecting factors include: poverty, socio-cultural and demographic, area of residence (urban and rural), age, parity, education, and economics, distance to provider, a mother is not entitled to make a decision, inadequate antenatal care's facilities, transportation, lack of family support that allows a woman to leave the house for maternal checkup. The objective of the study: to determine the effect of social support on the utilization of antenatal care based on customer driven in Balikpapan. The method of the study: The study is a survey research with cross sectional study. Sampling technique: Multistage random sampling. The samples were 210 women with babies aged 0-12 months. The analysis of the data used structural equation analysis namely Partial Least Square (PLS). Results: social support (support from friends, husband and social groups) is significantly correlated to the utilization of antenatal care (0.117). Conclusion: The need to build a good communication with family, friends and husband as the support is essential in antenatal care.

This paper modifies Chuang et al‟s[6] inventory model by adding service level constraint. In this study, I investigate the periodic review inventory model with a mixture of back orders and lost sales. The lead time varies with the ordered quantity. The set-up cost is not constant, it is controllable. Also, instead of having a stock out cost in the objective function, a service level constraint is employed. Furthermore, with the help of a numerical example the problem is described.

This conceptual paper is a review of the concept of strategic intent in relation to the strategic management theories. It reviews literature on strategic management theories stemming from the origin of the word strategic management to the current discussion on strategic intent. The concept of strategic intent inspires the management leadership as the way to bring future into current thinking thus allowing them to reorganize the organization for future competition by developing products, core competencies, systems and relationship that will give them a competitive edge. The paper has identified that strategic intent goes beyond the strategic planning to get a deeper imagination of where the organization should be 10 – 20 years into the future. This article is suggested to be an additional work into the understanding of strategic intent concept as one of the emerging issues in management

Participation has increasingly become one of the most vital ingredients of urban planning and development. In Uganda participatory planning has been given prominence with the rise to practice of planning policies and approaches that sought to democratize the country's development planning system. A major tenet in the democratization agenda was the establishment of a participatory system of planning in which local communities, facilitated by technocrats would participate in planning processes and influence the way physical planning functioned. Based on this unique value, this paper examines the level of participation of the urban community in physical planning process. This article focuses on an emerging urban centre of Paidha in northern Uganda. It shows that whereas participatory planning is recognised by many stakeholders, urban community inclusive, in practice nothing significant have been achieved. The level of urban community participation in physical planning is still very low. The study indicates that participatory planning plays a fundamental role in planning processes making it vital for physical planning. This study thus provides insights into the potential of urban participation for sustainable urban development. It therefore calls for community participation to be taken into account in efforts to promote planning process as an integral part of physical planning.

In this paper we consider a generalized Bessel-Struve operator ,n l on the real line, which generalizes the Bessel-Struve operator ,n l , we define the generalized Bessel-Struve intertwining operator which turn out to be transmutation operator between l and the second derivative operator 2 2 d dx . We build the generalized Weyl integral transform and we establish an inversion theorem of the generalized Weyl integral transform. We exploit the generalized Bessel-Struve intertwining operator and the generalized Weyl integral transform, firstly to develop a new harmonic analysis on the real line corresponding to ,n l , and secondly to introduce and study the generalized Sonine integral transform , , n m S  . We prove that , , n m S  is a transmutation operator from ,n l to ,n l . As a side result we prove Paley-Wiener theorem for the generalized Bessel-Struve transform associated with the generalized Bessel-Struve operator.

Solar still is simple device used to convert available saline water into drinking water. A conventional solar still is widely used for water purification but its efficiency is low. Numerous modelling and design attempts have been made to improve its performance i.e. increase the daily productivity of the still. This experimental study is carried out to evaluate the effect of using a separate condenser on the performance of a single slop solar still. This research work focused on the comparative study between solar still with separate condenser and conventional solar still. The result shows that the basin type solar still with separate condenser is 19% more efficient than the conventional still.

the recent years the usage of cast Al–Si alloy components in automotive and marine industries has increased significantly. Such alloys are invariably treated for modification and grain refinement prior to casting to achieve improved properties and performance. Grain refinement plays a crucial role in improving characteristics and properties of aluminum silicon eutectic (Al– 12Si) alloy. In the present research work, modified and grain refined Aluminium-Silicon alloys are synthesized from commercially available base alloys using die casting method. An attempt has been made to machine the eutectic Al–12Si (LM 6) alloy using CNC at different conditions. Modified Taguchi robust design analysis is employed to determine optimal combination of Machining parameters. The Analysis of Variance (ANOVA) is also applied to identify the most significant factor. It is found that the Depth of cut is the most significant factor on Material Removal Rate (MRR) and Feed rate is for Roughness of machined surface (Ra). It has been observed that there is good agreement between the predicted and experimental values of optimization. The influence of depth of cut and feed rate on MRR and Ra have been discussed. The addition of modifier and grain refiner had a crucial role in improving the mechanical properties in eutectic LM 6 alloy.

Cloud Computing is an up-and-coming technology now days in this bond in order to store and share enormous volume of data over internet we required Cloud Services. Cloud offering some services like IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS(Software as a Service) etc where it can control storage and share data securely with reduced cost thus sensitive personal Health records should be encrypted before outsource onto cloud for the sake of patient data privacy. As our existing system we noticed some of the privacy challenges over multi-keyword search from the cloud server. i.e patient revocation and lack of encryption scheme over index structure. In this paper we proposed a novel policy for patient revocation for avoiding patient revocation issues for dynamic updating over encrypted Health records by an authority i.e. Trusted Key manager(TKM) which manages keys by Diffie Hellman Algorithms: This algorithm is basically used to generate keys, and Cipher text- Policy Attribute-based Encryption (CP-ABE) is regarded as one of the most suitable technologies for data access control in cloud storage systems, because it gives the PHR owner more direct control on access policies and does not require the PHR to distribute keys. In CP-ABE scheme, there is an authority (TKM) that is responsible for key management. The PHR Owner defines the access policies and encrypts data under the policies using SHA-1. Each patient will be issued a secret key according to its attributes. A Patient can decrypt the cipher text only when its attributes satisfy the access policies under the fine grained approach scheme.

In this paper, a learning approach coupling region based and content based image processing is presented for Semantic image analysis in medical domain. Explicitly defined domain knowledge under the proposed approach includes objects of the domain of interest and their spatial relations based on the training set. The proposed algorithm contains 3 levels namely Annotation, Region analysis and Graphical representation. Finally the images are represented as graphs. Annotation is to find the organs present in the image and Region analysis is to find the dissimilarities. The abnormal conditions are clearly noted and revealed in graphs. The efficiency of graph is increased by the providing more information about the discrepancies. This gives the exact information what user requires and helps in easier understanding of Medical images.

Packet sniffing is a technique of monitoring every packet that crosses the network. A packet sniffer is a piece of software or hardware that monitors all network traffic. The security threat presented by sniffers is their ability to capture all incoming and outgoing traffic, including clear-text passwords and usernames or other sensitive material. While packet sniffers can be fully passive, some aren't, therefore they can be detected. This paper discusses the different methods that AntiSniff uses to detect these sniffing programs

This proposed controller supplements the voltage-sag compensation control of the DVR for downstream fault current interruption in a radial distribution line . It does not require phase-locked loop and independently controls the magnitude and phase angle of the injected voltage for each phase. Fast least error squares digital filters are used to estimate the magnitude and phase of the measured voltages and effectively reduce the impacts of noise, harmonics, and disturbances on the estimated pharos parameters, and this enables effective fault current interrupting even under arcing fault conditions. The results of the simulation studies performed in the PSCAD/EMTDC software environment indicate that the proposed control scheme: 1) can limit the fault current to less than the nominal load current and restore the point of common coupling voltage within 10 ms; 2) can interrupt the fault current in less than two cycles;3) limits the dc-link voltage rise and, thus, has no restrictions on the duration of fault current interruption; 4) performs satisfactorily even under arcing fault conditions; and 5) can interrupt the fault current under low dc-link voltage conditions.

Here in this paper a MAC layer level clogging detection system has been projected. The planned model aims to explore a system to compute the degree of clogging at victim node with maximal accuracy. This clogging detection apparatus is integrated with a Two-Step Cross Layer Clogging Control Routing Topology. The proposed model involves controlling of clogging in two steps with effective energy capable blocking detection and optimal cost of routing. Packet drop in routing is mostly due to link crash and clogging. Most of the existing clogging control solutions do not have the ability to distinguish between packet loss due to link collapse and packet loss due to clogging. As a result these solutions aim towards action against packet drop due to link malfunction which is an unnecessary effort and ends with of energy resources. The other limit in most of the available way out is the utilization of energy and resources to detect clogging state, degree of clogging and alert the source node about blocking in routing path. This paper explores a cross layered model of clogging recognition an control mechanism that include energy efficient clogging detection, Multicast Group Level Clogging Evaluation and Handling Algorithm [MGLCEH] and Multicast Group Level Load Balancing Algorithm [MGLLBA], which is a hierarchical cross layered base clogging recognition and avoidance model in short can refer as Qos Optimization by cross layered clogging handling (MGLCEH). This paper is supported by the investigational and simulation results show that better store utilization, energy efficiency in clogging detection and clogging control is possible by the proposed topology.

In this paper we have focused on the matter of discovering frequent temporal patterns in the database which contains temporal sequences, wherever a temporal sequence could be a set of things with associated dates as well as durations. Since the quantitative temporal info seems to be elementary in several contexts, it's taken under consideration within the mining processes and came back as a part of the extracted data. For this task we've got tailored the classical A Priori framework to propose an effective algorithmic rule supported by a hyper-cube illustration of temporal sequences. The extraction of quantitative temporal info is performed by employing a density estimation of the distribution of event intervals from the temporal sequences. Analyzing information sets shows that the projected algorithmic rule will robustly extract frequent temporal patterns with quantitative temporal extents.

Grid side converter Doubly fed induction generators' control strategy is proposed. To improve the performance characteristics of DFIG under grid voltage fluctuation. The control strategy is implemented to satisfy grid codes like grid stability, fault ride , power quality improvement, grid synchronization and power control etc. Doubly-fed Induction Generator system uses back-to-back converters in the rotor circuits to meet the necessary needs. Doubly-fed Induction Generator is the most common rotator machine which is used on the grid connected wind energy conversion system for the fulfillment of the system requirement such as grid stability, fault ride through, power quality improvement, and grid synchronization and power control etc. So in order to improve the operation capacity of wind turbine under critical situation, the intensive study of both machine side converter control and grid side converter control is necessary. The machine uses two back-to-back converters. The grid side converter is modeled to control the active power and reactive power independently along with dc-link voltage. This scheme allows wind turbines to remain synchronized to the grid during faults or during voltage sags and swings. The proposed control strategy is confirmed with simulation results in MATLAB/SIMULINK.

vImage search re-ranking is an effective approach to refine the text-based image search result. Text-based image retrieval suffers from essential difficulties that are caused mainly by the incapability of the associated text to appropriately describe the image content. In this paper, re-ranking methods are suggested address this problem in scalable fashion. Based on the classifiers for all the predefined Characteristics, each image is represented by an Characteristic feature consisting of the responses from these classifiers. A hyper graph can be used to model the relationship between images by integrating low-level visual features and Characteristic features. Hyper graph ranking is then performed to order the images. Its basic principle is that visually similar images should have similar ranking scores. It improves the performance over the text-based image search engine.

As the quantity of Web administrations with the same or comparable capacities increments relentlessly on the Internet, these days more administration customers give careful consideration to the nonutilitarian properties of Web administrations, otherwise called nature of administration (QoS), when discovering and selecting suitable Web administrations. For the vast majority of the QoS-mindful Web administration suggestion frameworks, the rundown of prescribed Web administrations is for the most part acquired in light of a rating-focused forecast methodology, going for anticipating the potential evaluations that a dynamic client may relegate to the unrated administrations as precisely as could be allowed. On the other hand, in some application situations, high precision of rating forecast may not as a matter of course prompt an agreeable proposal result. In this paper, we propose a combining so as to position focused mixture approach the thing based collective separating and inert element models to address the issue of Web administrations positioning. Specifically, the comparability between two Web administrations is measured as far as the connection coefficient between their rankings rather than between the conventional QoS evaluations. In addition, we additionally enhance the measure NDCG (Normalized Discounted Cumulative Gain) for assessing the exactness of the top K suggestions returned in positioned request. Thorough investigations on the QoS information set made out of certifiable Web administrations are directed to test our methodology, and the exploratory results show that our methodology beats other contending methodologies.

Cloud computing is a revolutionary computing paradigm, which enables flexible, on-demand, and low-cost usage of computing resources, but the data is outsourced to some cloud servers, and various privacy concerns emerge from it. Various schemes based on the attribute-based encryption have been proposed to secure the cloud storage. However, most work focuses on the data contents privacy and the access control, while less attention is paid to the privilege control and the identity privacy. In this paper, we present a semi anonymous privilege control scheme Anony Control to address not only the data privacy, but also the user identity privacy in existing access control schemes. Anony Control decentralizes the central authority to limit the identity leakage and thus achieves semi anonymity. Besides, it also generalizes the file access control to the privilege control, by which privileges of all operations on the cloud data can be managed in a fine-grained manner. Subsequently, we present the AnonyControl-F, which fully prevents the identity leakage and achieve the full anonymity. Our security analysis shows that both AnonyControl and AnonyControl-F are secure under the decisional bilinear Diffie–Hellman assumption, and our performance evaluation exhibits the feasibility of our schemes.

The point of this innovation to allude right name to the every face recognized in a given accumulation of pictures. For executing this system in this paper, we propose two new strategies. The objective of this procedure is just that to give right name to every face .We accomplish our objective by taking in two discriminative fondness frameworks from these pitifully named pictures. In this paper proposed another strategy called regularized low-rank representation. In this new strategy we are viably using feebly regulated data to take in a low-rank remaking coefficient framework which is investigating different subspace structures of the information. This is finished by acquainting an uncommonly composed regularizer with the low-rank representation strategy we proclaim the comparing recreation coefficients identified with the circumstances on the remade face. A discriminative partiality framework can be acquired from the gathered reproduction coefficient grid. In addition, we likewise add to another separation metric learning strategy called questionably directed auxiliary metric learning it is utilizing pitifully regulated data to look for a discriminative separation metric. Subsequently, utilizing the closeness network (i.e., the bit framework) another discriminative partiality lattice can be gotten taking into account the Mahalanobis separations of the information. In the wake of watching that every one of the two proclivity networks contain reciprocal data, we further consolidate them to acquire a melded liking grid; taking into account this fondness lattice we add to another iterative plan to allude the name of every face. By complete analyses show the viability of our methodology. This is alluring method for uncovering pitifully named picture dataset in multi-name annotation application.
