Title:	ICTS AND ECONOMIC GROWTH IN AFRICAN COUNTRIES
Author:	BASHIR S. GALADANCI
Abstract:	It is well established that Information and Communications Technologies (ICTs) are strong drivers for economic growth. While many studies have shown the strong correlation between ICT and economic development in a number of developed and developing countries, little research has been done on African countries in general and Nigeria in particular. This paper is aimed at identifying the relationship between ICT and economic growth in order to provide the way forward for Nigeria to use ICT for economic development. An analysis of the actual relationship between ICT and economic growth is made which identifies the necessary as well as sufficient factors that provide the catalyst to turn ICTs into drivers for economic growth. This is used to explain why the use of ICTs in many African countries does not result in the desired economic growth. A broad discussion is provided on the use of ICTs as a service sector as well as an economic sector. It is obvious that while both sectors can lead to economic growth, developing countries that use ICT as an economic sector are likely to do much better in generating wealth and providing job opportunities. A broad survey is made of the use of ICTs in Africa with particular emphasis to the experiences of a few countries namely Botswana, Mauritius, Egypt and South Africa. An attempt is then made to bring out the true relationship between ICTs and economic growth by analyzing the theoretical models on the major factors that drive ICTs in bringing about economic growth and emphasizing the way forward for countries that have not exploited ICTs as engines for economic growth.

Title:	SUCCESS FACTORS FOR KNOWLEDGE SHARING AMONG TVET INSTRUCTORS
Author:	HANIMASTURA HASHIM, HAIRULLIZA MOHAMAD JUDI, TENGKU SITI MERIAM TENGKU WOOK
Abstract:	Technical Vocational Education and Training (TVET) institutions are responsible for providing Human Resources particularly skilled and knowledgeable workers. In order to improve the quality of graduates in the technical field, the knowledge of TVET institution instructors should be strengthened from time-to-time. Knowledge sharing among TVET instructors can help them update their current knowledge. Information Technology enables TVET instructors to search for and share new knowledge more efficiently and quickly. They will also be able access a wider range of information. However, these knowledge-sharing activities often result in failure because most people prefer to seek knowledge rather than be its contributors. Therefore, this study is conducted to identify factors that influence knowledge-sharing activities among TVET instructors. A Qualitative method involving a semi-structured interview was conducted for this study. The Snowball Sampling method was chosen with four instructors and two experts as the respondents. Data analysis was performed using content analysis. This study identified the factors affecting knowledge-sharing activities via two main approaches: the non-technical approach, which consists of organizational, individual, content, and cooperation factors and the technical approach, which consists of just one factor i.e. technology. The factors identified are expected to help TVET institutions develop a knowledge-sharing repository that will encourage the sharing of knowledge among their instructors.

Title:	IMAGE SEGMENTATION USING HIDDEN MARKOV TREE METHODS IN RECOGNIZING MOTIF OF BATIK
Author:	MURINTO, EKO ARIBOWO
Abstract:	Batik is one of the inherited high-valued artwork. Batik is a way of making clothes using fabric coloring technique. This technique uses ‘malam’ to avoid staining unintended parts of the fabric. The term ‘Batik’ can also be referred to a cloth that is made with coloring technique, possesses certain motifs as well as special characteristic. Batik’s motif pattern recognition requires initial image processing step called as image segmentation. The purpose of image segmentation is to divide the image into several regions based on feature similarity including grayscale level, texture, color, and motion. In this research multiscale segmentation methods, HMTSeg, is used to recognize the pattern of batik’s motif. Images of Batik that have been used in this work are images of Batik originated from Jambi region, Pekalongan region, and Yogyakarta region. Batik’s motif pattern recognition steps include image pre-processing, image segmentation, and pattern recognition using Euclidean distance based method. Result shows that this method gained 80% of accuracy in recognizing batik’s motif. In conclusion, HMTSeg is a good segmentation method to recognize pattern of batik based on the texture.

Title:	OBSERVATION OF VIBRATION RESPONSE OF TYMPANIC MEMBRANE USING FINITE ELEMENT METHOD
Author:	MUHAMMAD RAFIQUL ISLAM, KOK BENG GAN, UMAT CILA
Abstract:	The middle ear plays an essential role in sound perception: it conducts air-borne sound energy from the external environment into liquid waves inside the inner ear via ossicular vibrations. However, the middle ear is often the site of infections, congenital disorders and other pathologies, which can lead to conductive hearing loss. Tympanometry is an acoustic method to evaluate middle ear function by measuring TM’s mobility and responses. However, current clinical results are inadequate due to our insufficient knowledge of the complex mechanics of the auditory system. This is a need to understand the TM vibration responses to the sound pressure level at certain frequencies. Such responses will find useful information such as displacement to develop a screening tool for middle ear diagnosis. Computational models have been introduced to analyze this phenomenon, where the tympanic membrane (TM) is key component in the auditory system. In this study, a finite element (FE) model has been proposed for TM. The geometry was reconstructed using magnetic resonance imaging (MRI) data. The material model was developed from previously published data. The model was employed to analyze the vibration of the TM under the sound load of pure tone. The vibration was observed for the sound load of 90dB SPL at three specific frequencies (226Hz, 678Hz and 1000Hz).

Title:	AN EXPLORATORY STUDY OF THE PROFILE OF THE SAUDI USER OF SOCIAL MEDIA
Author:	DIMITRIOS XANTHIDIS, ALI SAAD ALALI
Abstract:	The use of social networks is entering the era of maturity. The large technology vendors are all the more interested in getting involved in the Social Media game unable to afford being left out of these compact and huge potential markets. This exploratory quantitative study aims to reveal those demographics facts related with the usage of the social networks in Saudi Arabia that form the profile of the local user. The findings show a general agreement with the main conclusion of other public surveys in the country pointing to a heavy use of the social networks, at more than 85%. They also suggest that the younger the individual the more likely it is to get involved in the Social Media and in the case of female individuals, though slightly less in population, but seemingly more intense use of them. Education does not seem to affect the frequency of the use as long as the individual are at least basically educated. Likewise income and employment status only indirectly affect this use since they affect the amount of free time one has to get involved with the social networks. Finally, as expected, the more one is connected to the Internet the heavier the use of the Social Media.

Title:	STATIC STRUCTURE AND DYNAMIC VIEWS OF PURCHASES PROCESS AND MODELING IT IN ITERATIVE METHOD BASED ON USE-CASE SCENARIOS
Author:	F. ALAGHBARI, N. AKNIN
Abstract:	Our research comes to supplement the previous researches that have represented business process modeling languages. The representation performed in this paper is focuses on two most widely used iterative method based on Use-Case scenarios for purchase processes: static structure and dynamic views. To clarify how to use this method we applied it in purchase process by some steps. Use-Cases should be kept as simple as possible. Occasionally, however, we will encounter irreducible complexity and will need to formulate complex Use-Cases. Rather than trying to capture this complexity with lots of branching and alternative flows, it is easier, and less error prone, to model the main flows through this branching network as separate scenarios. The results presented in this paper as some models in UML. In addition, these models that facilitates the analysis phase of purchase process and make processes clear from perspective of analysts, managers, employers and also users. On the other hand, the aim in this paper will make the design phase easier and explained as a future work to complete the design phase of the purchase operations in implementation and testing phases.

Title:	COST EFFECTIVE APPROACH FOR SPATIAL MODELING
Author:	CAHYO CRYSDIAN
Abstract:	The paper presents an effort to standardize cost effective to support the development of spatial modeling. It is motivated by the increasing role of both cost effective and spatial modeling to contribute on society development worldwide. Therefore the future of spatial modeling would focus on minimizing cost and required time for model generation, in which cost effective become the only reliable approach to achieve these objectives. Considering that spatial modeling commonly consists of data acquisition, digitations process and model development, hence the characteristic of cost effective to minimize any required resources for system development is required to be presented in each stage. It means the method being utilized in each stage must comply with the objective of cost effective, thus method selection takes a vital role in the development process. The work has presented various strategies consisting of different methods being employed for model development in which each carries its own benefits and flaws. Finally it is important to consider available resources to meet with method selection in order to enable wise implementation of spatial modeling.

Title:	AN APPROACH TOWARDS SECURE MULTIKEYWORD RETRIEVAL
Author:	MERCY PAUL SELVAN , DR. A. CHANDRASEKAR, K. KOUSALYA
Abstract:	Extracting information from the database has become tedious process. Because redundant data will be extracted sometimes, so we are approaching a new method to extract the data from database. Giving single word as an input, we may not get relevant data, so multiple data can be given as input to extract the relevant information from the database, so that efficiency will be higher when compared to other methods. For security of data, we can encode the data on the admin side. Observations are done while queries were given to retrieve the data. The information was retrieved, joined and sorted using a top - k algorithm. The information are connected by a graph and status are reported.

Title:	A MODEL TO DETERMINE COST ESTIMATION FOR SOFTWARE DEVELOPMENT PROJECTS OF SMALL AND MEDIUM SCALES USING USE CASE POINTS
Author:	SHOLIQ, ARIFIN PUJI WIDODO, TEGUH SUTANTO, APOL PRIBADI SUBRIADI
Abstract:	The purpose of this study was to develop a cost estimation model for software development projects of small and medium scale. The model was derived from the Use Case Points, which is usually used to estimate software development effort. The development of our cost estimation model was based on the need for a reference to the estimated costs for software development projects, particularly software development projects of small–medium scale. The cost estimation was used to estimate the allocation of resources spent on covering personnel resources, money, and time to complete the project. The result of this study was a cost estimation model for software development projects of small–medium scale that had been tested with four software projects that had been completed. Testing of the model was performed using data from four projects got level deviations between the estimated cost and the actual cost amounted to 6.89%.

Title:	AUTHORSHIP ATTRIBUTION OF TELUGU TEXTS BASED ON SYNTACTIC FEATURES AND MACHINE LEARNING TECHNIQUES
Author:	N V GANAPATHI RAJU, Dr V VIJAY KUMAR, Dr O SRINIVASA RAO
Abstract:	The automatic recognition of an author of a document on the basis of linguistic features of the text is known as authorship attribution and the present paper performs this on one of the very popular and largely spoken languages of India “Telugu”. The present paper strongly believes that each author has got his own unique style of writing pattern, which is the signature of that author. The author attribution is similar to text categorization based on stylistic properties that deals with properties of the form of linguistic expression as opposed to the content of a text. The present paper is based on “shallow” features such as function words frequencies and part of speech (POS). The present paper experimented with a corpus that consists editorial articles of Telugu language by different journalists. The token and lexical based features are not considered because all the documents are in a similar genre and roughly constant over the different authors. The present paper focused on the use of syntax-based (shallow) features of an author's style, and evaluated most frequently used syntactic N-gram (unigram, bi-gram and tri-gram with and without overlapping) POS tagging features after performing the preprocessing step. The present paper also computed authorship attribution by considering Avyayas (similar to stop words in English language) of Telugu language. Further the present paper integrated the above two cases (POS tagging with Avyayas) in finding authorship attribution. Modern supervised machine learning algorithms are used by the present paper to explore large feature vectors to achieve high attribution accuracy. We have achieved an average of above 85% attribution rate on all classifiers with different feature vectors.

Title:	PERMISSION BASED MALWARE ANALYSIS FOR ANDROID APPLICATIONS USING SELF-ORGANIZING MAPS
Author:	AHMED BEN AYED
Abstract:	Android is an open source platform based on Linux kernel; it is one of the first operating systems that use a permission mechanism to control access to resources. The permission mechanism is fine gained and can control what a particular process could and could not perform. Therefore, these permissions should be monitored closely to make sure they are not assigned to the wrong application. This study is not intended to create an anti-malware solution, instead it uses the permissions to classify and categorize android applications. This paper is offering a novel way of using the self-organizing map to study a set of malware application and try to find a pattern of permission requests. This pattern could be used to analyze the application and compare it against the pattern identified earlier using the self-organizing map.
