The paper proposes a new model, method and algorithms for processing a Subject Domain (SD). It considers an SD as a tuple (E,V,T), where E is a set of all objects of this domain, V is a set of all connections between these objects, T is a set of mass problems that can be solved in this domain. Each object is represented by its essential attributes. This allows us to describe SD, to solve most of the mass problems from T, and to control a state of the domain. The goal of the paper is to develop a method and algorithms that allow us to find essential attributes of domains, described as relational databases or production systems. For a production system, we build a dependency graph with attributes as vertexes, and calculate for each of the vertexes a value that indicates how many other attributes can be found using a particular vertex. High-ranked vertexes are considered as essential. The method is based on considering as essential of the most frequently accessed attributes in a relational database. Having essential attributes of objects of a domain, it allows us to define essential attributes of the domain itself.

Due to rapid population growth, the demand for food is also elevating, which inspires farmers to embrace precision agriculture to increase production by exploiting predictive analytics on relevant real-time data. The exactitude of a prediction is vital to decide the next course of actions to be taken to compensate current demands, which again relies on a competent data acquisition technique. The Media Access Control (MAC) protocols have significant contribution in designing data acquisition technique. In this paper, we propose a new Store-and-Delivery base MAC (SD-MAC) protocol for Air-Ground Collaborative Wireless Networks (AGCWNs) to acquire data efficiently from the sensing devices which are deployed in the agricultural field. Our proposed protocol takes into consideration of the factors of network architecture and transforms them into advantages to attain higher throughput. The performance of the proposed protocol is evaluated using simulations and involving another such protocol, where the proposed protocol outperforms the other protocol.

In order to investigate the terrain changed in areas of urban, vegetation, bare land, and water type mapping in Pekan, Pahang of Malaysia using Landsat data. The data of a district of educational and research on years 2000 and 2013, were analyzed. First, will evaluating the quality of the image of Landsat data. There were no obvious errors noticeable on the geometric and radiometric. In order to estimate the accuracy of the map derived from classification, a ground truth map was prepared using strip sampling on map. Image classification was performed using original and synthetic bands for following four land types: urban, water, bare land, vegetation, and cloud types. Classification was performed using maximum likelihood (ML). The highest accuracy was obtained by using ML classifier. According to the results of this study, the spectral data of Landsat data have a large potential for land type mapping in Pekan area mapping.

Smart Internet Devices (SIDs) particularly Smartphones are soon turned to be super computers, while the restricted battery timing is a focused issue which hinders the steady meeting expectations yield of these devices. In addition, various sensors, high resolution LCDs, wireless interfaces, GPS and other advanced features drain battery quickly, thus, shrinking the operational time. Subsequently, increasing battery life of SIDs has happened to dire investigation significance at hardware and programming levels, both alike. The intention of our work is to evaluate computational offloading; sending power-intensive processing to remote servers in cloud and accepting the outcome back on device's screen. Furthermore, this paper gives a review of previous research work on computational offloading. We then summarize distinct research work with their respective findings and limitations. In addition, a short critical analysis of the review works following the summarized data.

Exhaustive testing of all possible combinations of input parameter values of a large system is impossible. Here, pairwise testing technique is often chosen owing to its effectiveness for bug detection. For pairwise testing, test cases are designed to cover all possible pair combinations of input parameter values at least once. In this paper, we investigate the adoption of Migrating Birds Optimization (MBO) algorithm as a strategy to find an optimal solution for pairwise test data reduction. Two strategies have been proposed; the first strategy implements the basic MBO algorithm, called Pairwise MBO Strategy (PMBOS) and the second strategy implements an improved Pairwise MBO strategy, called iPMBOS. The iPMBOS enhances the PMBOS with multiple neighborhood structures and elitism. Based on the published benchmarking results, these two strategies offers competitive results with most existing strategies in terms of the generated test size. We also noted that iPMBOS outperforms PMBOS in several parameter configurations, especially when the test size generated is relatively small.

Increasing cost and complexity of maintaining physical computers have caused large organization to consider alternative solution such as implementing Virtual Desktop Infrastructure (VDI) in their enterprise network. However, before deploying VDI solution in a large scale, it is essential to evaluate the sufficiency of the solution first. As a result, User Workload Simulator was developed. The simulator was used to evaluate two VDI solutions that are named VDI A and VDI B. The objective of the evaluation is to compare which solution can be a better VDI server host. From the result, VDI A is sufficiently better than VDI B for VM density per host. But in terms of network bandwidth utilization and Input/Output Operations Per Second (IOPS) consumption per host, VDI B is sufficiently better as it utilized less network bandwidth and consumed less IOPS on most of the user profiles evaluated.

IT organisations are facing risks that make IT projects not able to meet up planned schedule and quality. Hence, there is the need for risk mitigation in IT organisations to support IT team members to mitigate risk. This paper is a contribution to propose a risk mitigation model to provide expert assistance during IT risk mitigation. By assisting team members and decision makers to identify risks associated with in IT process by providing risk documentation to estimate the probability and impact of IT risks. The risk mitigation model can also introduce risk advice and suggest alternatives to treat the risk by providing support for the reuse of knowledge gained from past IT projects. The risk mitigation model will assist IT organisations in mitigating risk and making right decisions using a risk repository as a medium to provide support for practitioners in the mitigation of mainly operational and technical risk.

MapReduce has become the standard model for supporting big data analytics. In particular, MapReduce job optimization has been widely considered to be crucial in the implementations of big data analytics. However, there is still a lack of guidelines especially for practitioners to understand how the MapReduce jobs can be optimized. This paper aims to systematic identify and taxonomically classify the existing work on job optimization. We conducted a mapping study on 47 selected papers that were published between 2004 and 2014. We classified and compared the selected papers based on a 5WH-based characterization framework. This study generates a knowledge base of current job optimization solutions and also identifies a set of research gaps and opportunities. This study concludes that job optimization is still in an early stage of maturity. More attentions need to be paid to the cross-data center, cluster or rack job optimization to improve communication efficiency.

Internet of Things enabled Intra-Vehicular Network (IVN) refers to the network where large number of sensors are connected with each other for sharing the vehicle's status information in order to develop a smart vehicular system. The number of sensor nodes in the vehicle has increased significantly due to the increasing vehicular applications. The phenomenon of congestion poses a problem in the IVN where the traffic load and number of sensors are increased. This problem can be resolved by mitigating the limitation of the existing Media Access Control (MAC) protocols. In this paper, we address this issue and proposed a MAC strategy for solving this problem in this network. Furthermore, we discuss the design of IVN scenario and the performance is evaluated in terms of end-to-end delay. The simulation results reveal the effectiveness of our proposal.
