Collaborative knowledge representation processes and techniques to support domain experts in conceptual modeling

This thesis is focused in designing the appropriate means to help domain experts produce a welldefined account of a shared understanding (i.e., precise and accurate domain representations), in order to promote knowledge management and facilitate knowledge sharing in networked environments. This challenge implies developing, reusing and maintaining common interpretations of domain relevant information in a systematic way. This encloses specific knowledge acquisition and model abstraction problems, here tackled in a twofold perspective, establishing theoretical and practical connections to both terminology and knowledge representations, underpinned by a socio-semantic approach based on semiotic principles. In particular, here are discussed the challenges related to fostering and supporting the domain experts involvement in collaborative knowledge representation processes, driven by conceptualisation activities. The inherent (inter) subjectivity of the conceptualisation and its outcomes, together with its informality are the reasons for being an overlooked research topic in the literature. Conceptualisation activities, from the perspective of domain experts, should provide the appropriate artefacts to address conceptual representations as pragmatic artefacts, whose validity and value are time, context and situation dependent. For that, a Design Science Research methodology was followed. It aims towards the design and evaluation of the IT artefacts that could enable this informal and domain specialist oriented approach to the development of conceptual representations. Accordingly, particular attention was given to the following issues: • How to support conceptual relations elicitation? Relations elicitation revealed to be the major concern when performing conceptualisation activities, in particular if an informal perspective is followed. Moreover, the employed relations in the construction of a conceptual representation influence to which extent it can be reused. • How to enable the domain experts to bypass the initial difficulties of starting a conceptualisation? • How to find a tradeoff between the conceptual relations commitment with the real-world and the domain experts vision? This is crucial to endow conceptual representations with an highly reusability degree. To cope with that, an holistic approach was designed and accommodated into a conceptualisation framework as an abstract artefact supporting conceptual representations construction in a 3-layered formalisation approach. At the end, the goal is to achieve computational and wellformed conceptual representations (i.e., compliant with a well-defined representation schema), without the need for domain experts to commit to any other formalism than those from their own technical field. The conceptualisation framework and its constructs were implemented in a technological platform mediating the cycle of development and evaluation of the artefacts, following qualitative

Generalized Super-Vector Coding for Image Classification

Semantic understanding of images remains an important research challenge in machine intelligence and statistical learning. It mainly includes two steps: feature extraction and classification. This study mainly aims to explore a generalized feature extraction framework motivated by the popularly used Bag-of-feature (BOF) and super-vector coding using local descriptor, which is intuitively time -consuming for computation. In the other hand, the effortless on only exploring color and edge histogram with uniformly quantized space, which are conventional statistics, make less progress in image understanding field. Therefore, This study investigates a generalized framework based on the accessible color or edge information via adaptively modelling the explored space of a specific application, and then extracts the representation statistics (histogram of the data-driven model) and deviation statistics (the statistics of reconstruction error) for image representation. Compared to the uniformly quantized strategy such as the conventional histogram, the proposed framework can represent the image more faithful and compact, and then lead to more discriminant representation for images. With the extracted data- driven statistics, a simple linear support vector machine (SVM), which is especially efficient for large-scale database, can be effectively utilized for achieving acceptable recognition performances. Experiments on two databases: SIMPLICity and OMRON validate that our proposed strategy can achieve much better recognition performances than the conventional and the state-of-the art methods.
Predicting Academic Performance with Applying Data Mining Techniques (Generalizing the results of two Different Case Studies)

Several research works are attempted to predict students academic performance and assess the evaluating students knowledge or detecting students’ weakness and probability of failure in final semester examinations. However, several factors affect the performance of students in different countries or even in different states of one country. Therefore, understanding these factors and analyzing the effects of each one of those factors in each country, is necessary for improving instructors’ decisions in selecting the best teaching method for helping weak students or increasing performance of other students. This study is motivated to study the students’ academic performance in high school and bachelor degree studies in Iran and comparing these analysis results with the similar study’s results in India.
Semantic Web Portals: Design and Development Technologies and Tools

Ansari, Aftab 2012. Semantic Web Portals: Design and Development Technologies and Tools: Bachelor’s Thesis. Kemi-Tornio University of Applied Sciences. Business and Culture. Pages 67. Semantic Web is one important and relevant research area in computer science. A growing research attention to this field can be explained by the opportunities the Semantic Web could provide by representing and reasoning about semantic information. The objective of this thesis is to study the technologies for building information architecture and tools for technical implementation of Semantic Web Portals (SWPs). In particular, this thesis focuses on the concepts of ontology and the formalisms for representing ontologies within SWPs. These formalisms include, for instance, RDF (Resource Description Framework) and OWL (Web Ontology Language). There are many software tools, for example, Protégé, Jena and OntoStudio, intended for the practical implementation of ontologies and these are overviewed and analyzed in this work. In addition, the thesis focuses on two implementations of SWPs in Finland, namely, HealthFinland and MuseumFinland. Based on these research results this thesis proposes the idea of building a SWP for Finnish educational system. The discussion of the information architecture for the proposed SWP is limited to Kemi-Tornio UAS due to the time allocated for thesis research. Nevertheless, the results of the work prove that this idea is relevant and implementable and will bring benefits to a wide category of users both general public and the education professionals. The main research methodology used in this thesis is exploratory research based on the literature use and analysis. There are plenty of books and academic articles published in this research area. This research work is largely theoretical although the practical idea following the research results is presented and its implementation is suggested. Finally, opportunities for continuing this research work are discussed.
Optimal location of shunt FACT devices for Power flow control in power System

Power flow control, in an existing long transmission line, plays a vital role in Power System area. In this the shunt connected compensation (STATCOM) based FACTS device for the control of voltage and the power flow in long distance transmission line. The proposed device is used in different locations such as sending end of the transmission line, middle and receiving end of the transmission line. The PWM control strategy is used to generate the firing pulses of the controller circuit. Simulations were carried out using MATLAB Simulink environment. The suitable location and the performance of the proposed model were examined. Based on a voltage-sourced converter, the STATCOM regulates system voltage by absorbing or generating reactive power. The simulation results reveals that the reactive power generated is better at the middle of the transmission line when compared with the other ends of the transmission line and also the voltage is controlled at the middle of the line. Henceforth the location of STATCOM is optimum when connected at the middle of the line. Keywords— FACTS device, STATCOM, PWM technique, MATLAB Simulink.
Application of Bioimpedance Analysis of Female Body Compositionin the Training Process of Fitness Orientation

The article presents the material of the results of studying the components of body weight composition of female students of higher educational establishments using computer measuring technology of bioimpedance. Special features of the are the basic parts of forming the indicators of general and special performance in sports and fitness. Along with this, the body changes under the influence of the specifics of training loads and under the influence of increasing physical and functional fitness of students. Therefore, the information about the components of body weight composition allows to individualize physical activity on training sessions using a variety of physical exercises and kinds of sports. Female students with higher of bioelectrical indicators (phase angle, reactance), the active cell mass (ACM) and the percentage of the active cell mass dominate in the physical and functional fitness relatively students with low indexes. These differences are statistically significant (P DOI: 10.5901/mjss.2015. v6n3s7p369
Detection and recovery of a narrow-band signal in severely nonstationary noise

The authors view the interference as a stochastic process n(m,t) in two variables. They assume a uniform linear array that the carrier frequency is known and that the direction of arrival of the desired signal does not change. The approach is an application/extension of the multi-window method for spectrum estimation and harmonic analysis introduced by Thomson (Proc. IEEE vol.70, no.9, p.1055-96, Sept.1982). How the signal is estimated if present, and how to estimate the DOA, are discussed briefly. <<ETX>>
A 0.5-μm CMOS T/R switch for 900-MHz wireless applications

A single-pole double-throw transmit/receive switch for 3.0-V applications has been fabricated in a 0.5-/spl mu/m CMOS process. An analysis shows that substrate resistances and source/drain-to-body capacitances must be lowered to decrease insertion loss. The switch exhibits a 0.7-dB insertion loss, a 17-dBm power 1-dB compression point (P/sub 1 dB/), and a 42-dB isolation at 928 MHz. The low insertion loss is achieved by optimizing the transistor widths and bias voltages, by minimizing the substrate resistances, and by dc biasing the transmit and receive nodes, which decreases the capacitances while increasing the power 1-dB compression point. The switch has adequate insertion loss, isolation, P/sub 1 dB/, and IP/sub 3/ for a number of 900-MHz ISM band applications requiring a moderate peak transmitter power level (/spl sim/15 dBm).
A complex noise reduction method for improving visualization of SD-OCT skin biomedical images

In this paper we consider the original method of solving noise reduction problem for visualization’s quality improvement of SD-OCT skin and tumors biomedical images. The principal advantages of OCT are high resolution and possibility of in vivo analysis. We propose a two-stage algorithm: 1) process of raw one-dimensional A-scans of SD-OCT and 2) remove a noise from the resulting B(C)-scans. The general mathematical methods of SD-OCT are unstable: if the noise of the CCD is 1.6% of the dynamic range then result distortions are already 25-40% of the dynamic range. We use at the first stage a resampling of A-scans and simple linear filters to reduce the amount of data and remove the noise of the CCD camera. The efficiency, improving productivity and conservation of the axial resolution when using this approach are showed. At the second stage we use an effective algorithms based on Hilbert-Huang Transform for more accurately noise peaks removal. The effectiveness of the proposed approach for visualization of malignant and benign skin tumors (melanoma, BCC etc.) and a significant improvement of SNR level for different methods of noise reduction are showed. Also in this study we consider a modification of this method depending of a specific hardware and software features of used OCT setup. The basic version does not require any hardware modifications of existing equipment. The effectiveness of proposed method for 3D visualization of tissues can simplify medical diagnosis in oncology.
A Comparison of Traditional and Hybrid Online Instructional Presentation in Communication Technology

Introduction Online education has become a central element of the discourse on higher education (Cox, 2005). There seems to be an overall drive toward online learning given the mounting need for flexibility in scheduling and the daily emergence of communication technologies and capabilities (Hillstock, 2005). Online education is presented as a means of conveying instruction to an extensive learning community any place at any time. Cox (2005) indicates that advocates designate online learning as the driving force and model for transformation in teaching, learning, and formal schooling. Online courses have the potential to provide learners with individualized attention by the instructor, otherwise impossible in a large classroom environment (Environmental Education and Training Partnership, 2006). With the continuing development of online instructional applications, many colleges and universities have begun to offer online courses as an alternative to traditional face-to-face instruction. Sixty-seven percent of colleges and universities agree that online education is the most logical long-term strategy for their institution (Hillstock, 2005). However, there are considerable hesitations rising, predominantly related to quality and student responsiveness to online education (Yang and Cornelius, 2004). Just as there are advantages there are also disadvantages to the online instruction delivery method. There is evidence through previous research that students feel isolated or disconnected when not engaged in traditional face-to-face instruction (Guhu, 2001; Graham, 2001), while other reports indicate large successes (Hoffman, 2002; Kaczynski and Kelly, 2004; Meyer, 2002). There remains a lack of clarity whether online courses are as effective as traditional courses (Poirier and Feldman, 2004). While there has been a vast amount of research conducted on the advantages and disadvantages of online instruction, little is known on how assessment is used in online classrooms to monitor performance and progress (Liang and ____________________
Using online courseware for information literacy skills development in a multinational program

Information literacy skills are becoming a world-wide educational issue. Chalmers and Fuller (1996) suggest that we should not assume students commence university with the ability to develop sustained learning strategies that are consistent with the type of learning we wish them to acquire. This often results in students’ inability to make the best use of the learning opportunities with which they are presented. One skill of particular importance is information literacy.
Software Metrics: Measurement for Software Process Improvement

From the Publisher: Software Metrics explains how software measurement can be used to support software process improvement by providing objective methods of characterizing process capability and evaluating the effect of process changes. The author explains what is meant by software measurement and how to decide what to measure; how to use measurement to support different aspects of a process improvement programme; how to set quantitative goals using a pragmatic approach to the Goal-Question-Metric paradigm; how to set up a metrication programme and design a data collection system; and how to analyse the software data collected. Further, the author provides insight into how software measurement can act as a process improvement agent for quality control and software estimating. This book sets out an approach to the formal validation of measures and the theory of statistical data analysis for students. It also contains, for practitioners, many examples of the use of real data in real projects.
Biological Data Modelling and Scripting in R

s in R so as to get a file containing PMIDs, Titles, Abstract Text and Journal Name in separate columns. We create the S4 class object of this Abstract file. Now if we have to search for any abstract containing a pattern or word of our interest we use regexpr function in R to get all those abstracts e.g. pathway. From these filtered Glioma pathway abstracts a Corpus (collection of large text) is generated using tm package function. This Corpus is subjected to Stemming, Stop word removal, common English word removal using R libraries rJava, RWeka (Hornik et al, 2009), RWekajars, slam, Snowball (Hornik, 2009), Corpora. We can set other controls as well. Now we can create term document matrix from this Corpus, containing all terms as rows and abstracts as columns. From this term document matrix we can extract the terms withins as columns. From this term document matrix we can extract the terms within different frequency ranges i.e., their number of occurrences in each abstract indicating their importance. Thus we can predict that terms which have higher frequency of occurrence in the matrix are more important and are related in some sense. We have filtered all the terms with frequency of their occurrence greater than 5.

Enforcing Data Privacy in Outsourced Database Services

Advances in networking technologies and the continued growth of the internet have triggered a new trend towards outsourcing data management and information technology needs to external service providers, and privacy requirements have an increasing impact on such real-world applications. In this paper, we propose a solution to enforce data privacy over outsourced database services. The approach starts from a flexible definition of privacy constraints on a relational schema, applies encryption on information in parsimonious way and mostly relies on attribute partition to protect sensitive information. Based on the approximation algorithm for the minimal encryption of attribute partition and the decomposition of SQL queries, the approach allows storing the outsourced data on a single database server and minimizing the amount of data represented in encrypted format, and allows executing queries over encrypted outsourced database efficiently.
Leveraging Spreadsheets to Learn the Mechanics of Accounting

Abstract: As teachers in Introductory Financial Accounting courses, we frequently face the question of whether to teach the mechanics of the accounting process or to focus on analyzing the financial statements themselves. The truth of the matter is that students who understand the mechanics of the accounting process are far more successful at analyzing financial statements than those who have never learned the mechanics. Thus, the question becomes: How can one simply introduce the mechanics of accounting without burying students (especially those who do not intend on becoming accountants) in the detailed accounting terminology of debits, credits, and T-accounts? We present a simple and yet effective means of achieving this objective. Our students create spreadsheets to capture the accounting entries and to generate financial statements. Here we describe the features of the spreadsheet and discuss the advantages that this method enjoys over more traditional ways of teaching the mechanics of accounting.
Logo Studies and Their Effect on Learners’ Attitudes Toward Computer Programming

AbstractThe purpose of this paper is to describe some of the alms and characteristics of the computer course An Introduction to Computer Science via Logo, developed at the Israeli Logo Center, the Technion. The article investigates, in a case study context, the effects of these aims and characteristics on high school learners’ attitudes toward computer programming principles. The effect of class size and socioeconomic status (SES) on these attitudes will also be considered. The findings indicate that after being exposed to the Logo course, learners from low SES backgrounds had attitudes toward programming principles that were at least as positive as, if not slightly more positive than, those of learners from high SES backgrounds. This was the case despite the fact that lower SES students attended larger classes, had lower achievement levels, and initially had lower self-evaluations concerning their own mastery of computer programming.
Keyboarding Aids

Abstract Elementary schools across the United States are striving to find the most effective method of teaching keyboarding to their students. A number of schools make use of sensor-key capson the Dand the Kkeys. These caps have eight elevated dots forming a circle in the center of the cap. Educators would benefit from knowing if, indeed, these key caps make a significant difference in students' abilities to keyboard with increased speed and accuracy when compared to standard keys. This study was conducted on two groups of third-, fourth-, and fifth-grade students (N= 95) who completed a keyboarding unit. One group used the sensor-key caps and the other group did not. Results provided no evidence that the use of sensor-key caps improved keyboarding speed or accuracy over standard keys without the key caps.
