This position paper presents the outline for a study of the changes in geography and organisation of the global knowledge economy and how the development of outsourcing and localisation of firms from the “global south” in the “global north” within ICT industry is supported by ICT tools.
While on-line shopping is considered as a special type of e-service, the adoption rate of this service in Taiwan has been paid attention recently. The initial adoption of on-line shopping is the important driving force to further influence the use and continued use of this service. The model of Trust and technology acceptance model (TAM) in Gefen et al. [1] has been well studied in on-line shopping...
Automatic face recognition remains a challenging task due to factors such as variations in recording condition, pose, and age. Many schemes have emerged to enhance the performance of face recognition to deal with poor quality facial images. It has been shown that reporting average accuracy, to cover a wide range of image quality, does not reflect the system's for any specific quality levels. This...
Presenting search results as a list of hits can be ineffective in assisting users to find relevant documents and discover varied topics among search results. Visualization can assist users to find relevant documents and make the search interface more effective. This paper presents a Data Mountain Search Results Presentation Interface (DMSRPI). The interface is intended to improve the effectiveness...
The development of digital libraries in Poland was initiated about ten years ago with the start of the dLibra project. This project was aiming for the creation of a software package to facilitate building flexible digital libraries for scientific and cultural institutions. The success of the package and the idea behind it caused rapid increase of the number of digital libraries, reaching 60 on-line...
The explosive growth of recommender systems has resulted in realization of individualized service as commercial patterns and research prototypes. However, the traditional recommendation approaches are overemphasized the similarity between user preference and items feature. They are completely ignored affectivity that was a crucial factor. Our study focuses on exploring a new affective recommendation...
A considerable number of Learning Games have been published over the last years. Since there are no clear guidelines for developers, they may not always meet the learner's expectations. Games are a powerful mediator for learning, but flaws in planning and design can have a negative effect on their potential. This paper describes the design of two Serious Games in a socio-cultural context. Special...
Nowadays, numerous teachers are using Technology Enhanced Learning systems in various domains. The tracks analysis concerning students' actions logged by Technology Enhanced Learning systems can help teachers to improve their pedagogical scenarios making them more relevant to students. Very often analysis solutions are developed ad hoc and without considering the teachers observational needs. In our...
Different approaches have been developed to provide technical support for mobile learning. Most these approaches consider only the physical properties of learning environment. In this work, we not only focus on the physical/spatial dimension of the learning environment of the city, but also pay attention to the notion of Place which is a meaningful outcome of peoples understanding of Space. This paper...
Usability and accessibility have been guiding interaction designers in their endeavor for better user interfaces. Recently, emotions and human values are gaining space, demanding new directions for the design of systems. As an emerging subject, the need for models that associate emotions and affective quality with human-computer interaction design is still to be addressed. This paper presents a literature...
This paper focuses on the knapsack scheme suggested by Hwang, which is relied on a new method entitled permutation combination method. The findings show that this permutation method is not efficient to the security of the scheme since, we can break this scheme employ the algorithm provided by Shamir scheme. Finally, we provide an enhanced version of Hwang scheme to avoid this attack.
Wireless Sensor Networks (WSNs) are receiving increased focus due to their applicability to crucial applications like military, healthcare, habitat monitoring etc. However, wireless communication poses additional threats to the critical information being sent over the wireless media. Therefore there is a dire need to have a secure way of communication for a WSN. Public Key Cryptography (PKC) holds...
