Concomitant with these developments is the revolution in the capability and ubiquity of mobile systems. The result of these developments is interest in personalized e-learning provided on-demand using mobile technologies. Additionally, e-learning is utilizing Web 2.0 technologies to enable personalized collaborative networking at both a pedagogic and personal level. Personalization requires the creation of a user profile (a context), a context reflects a user's current state. This paper addresses personalized e-learning in the domain of higher education. Following an overview of the educational landscape e-learning the related Web 2.0 influences will be considered and technology enhanced learning discussed.

We applied the present procedure to the characteristic gene sets of seven subtypes of testicular germ cell tumors in a previous report. The cellular relationships were well reconstructed, consistent with the general histologic lineage model, and new implications for the subtype differentiation were found. In particular, the correspondence between the inferred relationships and the functional characterizations of constituent genes suggests a hypothesis for the classification between seminoma and embryonal carcinoma. The partial canonical correlation analysis is also appropriate for revealing new features of cellular relationships, based on the transcriptional programs. Thus, the present procedure helps to create a macroscopic view of the cellular relationships, by following the detection of the characteristically expressed genes.","PeriodicalId":158978,"journal":{"name":"2012 Sixth International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121495052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Feature extraction is traditionally founded on pattern recognition methods exploiting the basic concepts of convolution and Fourier transform. For color image edge detection the traditional methods used for gray-scale images are usually extended and applied to the three color channels separately. This leads to increased computational requirements and long execution times. In this paper we propose a new, enhanced version of an edge detection algorithm that treats color value triples as vectors and exploits the geometric product of vectors defined in the Clifford algebra framework to extend the traditional concepts of convolution and Fourier transform to vector fields. Experimental results presented in the paper show that the proposed algorithm achieves detection performance comparable to the classical edge detection methods allowing at the same time for a significant reduction (about 33%) of computational times.","PeriodicalId":158978,"journal":{"name":"2012 Sixth International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122537691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the notion of 'intuitive guided' learning, this paper presents an approach which seeks to facilitate a structured learning experience whilst allowing learners to explore a non-linear environment. To do so, a framework is presented which externalizes the assessment process in a serious game, whilst also providing a means for game content to be adapted dynamically to translate the outcomes of the assessment process to effective feedback. A developed prototype is implemented to examine the theory in-practice through the case of a game for civil defence training in schools. Using this prototype, a range of methods in which achievements might be related to learner actions are introduced, and their subsequent implications for intuitive learning discussed. Furthermore, the prototype illustrates how assessment rules can be defined as external to the game and subsequently used to generate feedback for a virtual companion who assumes the role of a more-able partner. The long-term potential of such methods as a source of data on player behaviour is discussed, suggesting further benefits the technique might offer to educators seeking to introduce game-based learning within the curriculum in a blended fashion.","PeriodicalId":158978,"journal":{"name":"2012 Sixth International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130838225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, one observes from computer simulation that the values of clipping and scaling parameters are quite different in image enhancement for various blurred images. Therefore, one aim of this paper is to develop an effective image classification technique to decide the best combination of clipping and scaling parameters by the opportunity cost method for image enhancement. Experimental results show that the proposed opportunity cost method with image classification for the nonlinear image enhancement achieves a better subjective and objective image quality performance than the method using the opportunity cost without image classification and other nonlinear image enhancement methods.","PeriodicalId":158978,"journal":{"name":"2012 Sixth International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"60 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124089516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How can educators reach the Millennial students and provide a productive and engaging learning environment? Guided learning activities, like digital storytelling, help learners bridge the gap between the real context and the learning theories. The aforementioned activities prepare students to learn in situations they may encounter at work and in their personal life. The construction of interactive narratives represents an educational challenge gaining in a considerable importance when they take into account the emotions felt by the users and exploit them to improve themselves. In this work, we propose to include the Emotion Management into a pedagogy-driven template, based on storytelling, and to extend the Storytelling Design Model through an Emotion Tracking Engine used to keep track of users' emotional states. Furthermore, a Story Logic Engine will be used to rebalance altered emotions and maximize the acquisition of knowledge, by assigning a different role to the student. Roles are selected by means of a mapping function that associates narrative archetypes with detected emotions.","PeriodicalId":158978,"journal":{"name":"2012 Sixth International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124975736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
