<![CDATA[Opportunistic accessing of vacant channels of licensed spectrum by non-licensed wireless devices offers a convenient solution to the spectrum scarcity problems experienced by many wireless communication systems. Due to the fixed assignment policy of spectrum, some of the licensed frequencies are not in full utilization by their licensed users. On the other hand, there exists a severe scarcity of bandwidth for new wireless services. In this context, opportunistic access is found to be a boon, to overcome the spectrum scarcity problems. In this paper, opportunistic accessing of vacant channels by the wireless sensors is analysed. Finding the number of devices that can be supported for the available vacant bandwidth is the main focus of the work. Assessing the blocking probabilities experienced by the devices is found to offer an approximation of the number of devices that can be accommodated in a given scenario, for permissible blocking rates. This kind of analysis can help in proper planning of such wireless sensor networks, to deploy them in a way that they can make use of the white space bandwidths efficiently. ]]>

<![CDATA[This paper presented a new multilingual language for Automated Teller Machine (ATM) in Uganda which serves as an extension to the existing Languages. The existing ATMs have only English, Kiswahili and Luganda as the only available languages. Hence, findings revealed that there are still some prevalent languages e.g. Ateso language that are widely spoken among the people of Uganda which the present ATMs in the country have not captured. The objective of this paper was to propose the integration of the new language (Ateso language) to the existing languages. In this paper, a new language was adopted when it was realized that some people especially in the Buganda region could not manage to interact with the ATMs because they were illiterate. The developed multilingual system prototype was tested using some empirical data and was found to successfully imitate ATM transactions in the local Uganda languages. The results of the study supported the positive impacts on customers that reside in the rural areas since its improved interaction of more users on the ATMs. This paper demonstrated the use of Ateso language for different transactions on the ATM system. The implementation by the banking institutions can aid the ATM users to make more flexible decisions on the usage of the ATM machines.]]>

<![CDATA[Retrieving images from large databases becomes a difficult task. Content based image retrieval (CBIR) deals with retrieval of images based on their similarities in content (features) between the query image and the target image. But the similarities do not vary equally in all directions of feature space. Further the CBIR efforts have relatively ignored the two distinct characteristics of the CBIR systems: 1) The gap between high level concepts and low level features; 2) Subjectivity of human perception of visual content. Hence an interactive technique called the relevance feedback technique was used. These techniques used user’s feedback about the retrieved images to reformulate the query which retrieves more relevant images during next iterations. But those relevance feedback techniques are called hard relevance feedback techniques as they use only two level user annotation. It was very difficult for the user to give feedback for the retrieved images whether they are relevant to the query image or not. To better capture user’s intention soft relevance feedback technique is proposed. This technique uses multilevel user annotation. But it makes use of only single user feedback. Hence Soft association rule mining technique is also proposed to infer image relevance from the collective feedback. Feedbacks from multiple users are used to retrieve more relevant images improving the performance of the system. Here soft relevance feedback and association rule mining techniques are combined. During first iteration prior association rules about the given query image are retrieved to find out the relevant images and during next iteration the feedbacks are inserted into the database and relevance feedback techniques are activated to retrieve more relevant images. The number of association rules is kept minimum based on redundancy detection.]]>

<![CDATA[For the past 20 years various researches regarding software aging have been conducted. Software aging is the situation in which the accumulation of errors occurring in operational software system that has run for a long time that may lead to performance degradation, resource depletion and eventually causing the software to crash or hang [1]. David Parnas divided software aging into two categories: 1) the failure of the software to adapt with environment that is dynamic and 2) the result of the changes itself [2]. Factors that can affects software aging can be classified into several categories: 1) functional, 2) human, 3) product and 4) environment [3]. In general, the factors that affect software aging can be divided into internal and external factors. The main objectives of this paper are to briefly describe the definition of software aging and also ICTS governance. In addition to that, this paper also compiles the software aging factors that are being investigated by previous researchers. The need for future research regarding ICTS governance and Software aging also determined at the end of this paper. ]]>

<![CDATA[Semantic web is an addition of the previous one that represents information more significantly for humans and computers. It enables the description of contents and services in machine readable form. It also enables annotating, discovering, publishing, advertising and composing services to be programmed. Semantic web was developed based on Ontology which is measured as the backbone of the semantic web. Machine-readable is transformed to machine-understandable in the current web. Moreover, Ontology provides a common vocabulary, a grammar for publishing data and can provide a semantic description of data which can be used to conserve the Ontology and keep them ready for implication. There are many that used in feature based in semantic similarity. This research presents a single ontology of X-Similarity feature based method.]]>
