Factors in the global assimilation of collaborative information technologies: an exploratory investigation in five regions
2008
The diffusion of innovation theory is deployed to investigate the global assimilation of collaborative information technologies (CITs). Based on the concepts of IT acquisition and utilization, an assimilation framework is presented to highlight four states (limited, focused, lagging, and pervasive) that capture the assimilation of conferencing and groupware CITs. Data collected from 538 organizations in the United States, Australia, Hong Kong, Norway, and Switzerland are aggregated and analyzed to explore assimilation patterns and the influence of decision-making pattern, functional integration, promotion of collaboration, organization size, and IT function size on the assimilation of CITs.…
Developing a formative assessment system for mathematics using mobile technology: A student centred approach
2012
The success of mobile technology for learning tools depends not only on the technical design aspects but also on pedagogical issues. Students' involvement in designing the tools is one of the key factors for their engagement in technology supported learning. Students should be actively involved in developing innovative solutions which are likely to improve their skills as well as their performance. In this study work, the students participated in iterative design processes of a mobile tablet based peer-to-peer assessment system (P2PASS) for mathematics, and in real life deployment on a mathematics course. The paper reports on two major concepts: the user centred design in practice and the p…
Social Computing: A Classification of Existing Paradigms
2012
In less than three decades, several paradigms of social computing have emerged. Among them, groupware, social software and mobile social software (MoSoSo) are the most widely known. Although all significant, it is challenging to recognize the function and unique features of each single paradigm. This situation represents an obstacle for a coherent development of social computing, a research domain that is highly fragmented and with relevant literature spread across several disciplines. In this paper, a classification of existing social computing paradigms is introduced as an initial effort to combine the lines of discourse concerning social computing.
MADE – A Groupware Application to Support Real-Time Activities of Distributed and Cooperating Communities
2003
Abstract. Distributed work has increased during the last few years. Employees travelling around in different countries still need access to information and must be reachable by their colleagues. A variety of mobile devices have been utilised for this purpose. However, often, when using multiple devices, the information is available to the appropriate device only. Transferring data between the devices is not always an intuitive or easy thing to do – not while conversing at least. This paper presents a groupware application to support real-time actions of distributed communities. The problem of separate devices is addressed by combining multiple tools, media, into a platform independent aggre…
On the uniform sampling of CIELAB color space and the number of discernible colors
2013
This paper presents a useful algorithmic strategy to sample uniformly the CIELAB color space based on close packed hexagonal grid. This sampling scheme has been used successfully in different research works from computational color science to color image processing. The main objective of this paper is to demonstrate the relevance and the accuracy of the hexagonal grid sampling method applied to the CIELAB color space. The second objective of this paper is to show that the number of color samples computed depends on the application and on the color gamut boundary considered. As demonstration, we use this sampling to support a discussion on the number of discernible colors related to a JND.
Software for simulating dichromatic perception of video streams
2013
We have designed a configurable stand-alone Matlab-based software to simulate dichromatic perception of video streams. The algorithm used is an extension for video streams of the “corresponding pair algorithm” by Capilla and coworkers for simulation of dichromatic perception of images. The software allows the user to upload a video sequence and to process it using different dichromatic color vision models and viewing conditions. The output video may be generated in different spatial and temporal resolutions and file formats. The functions for Matlab environment and a stand-alone application may be downloaded from the Repository of the University of Alicante. © 2013 Wiley Periodicals, Inc. C…
Colour image segmentation and labeling through multiedit-condensing
1992
Abstract A new method is proposed for detecting and locating objects of interest within a colour scene under very strong variabilities in lighting conditions, object shape and pigmentation. The method is based on Nearest Neighbour classification and Multiedit-Condensing techniques and is applied to implement the vision subsystem of a robotic citric harvesting device. Experiments and results are reported showing the effectiveness of the method and illustrating its appropriateness to the proposed task.
Prototype selection for the nearest neighbour rule through proximity graphs
1997
Abstract In this paper, the Gabriel and Relative Neighbourhood graphs are used to select a suitable subset of prototypes for the Nearest Neighbour rule. Experiments and results are reported showing the effectiveness of the method and comparing its performance to those obtained by classical techniques.
LR(k) Parsing
1990
In this chapter we shall generalize the notion of strong LL(k) parsing presented in Chapter 5 and consider a method for deterministic left parsing that applies to a slightly wider class of context-free grammars than does the strong LL(k) parsing method. This method will be called “canonical LL(k) parsing”. As in strong LL(k) parsing, the acronym “LL(k)” means that the input string is parsed (1) in a single Left-to-right scan, (2) producing a Left parse, and (3) using lookahead of length k.
A Note on a Conjecture of Duval and Sturmian Words
2002
We prove a long standing conjecture of Duval in the special case of Sturmian words. Mathematics Subject Classication. ??????????????. Let U be a nonempty word on a nite alphabet A: A nonempty word B dierent from U is called a border of U if B is both a prex and sux of U: We say U is bordered if U admits a border, otherwise U is said to be unbordered. For example, U = 011001011 is bordered by the factor 011; while 00010001001 is unbordered. An integer 1 k n is a period of a word U = U1 :::U n if and only if for all 1 i n k we have Ui = Ui+k. It is easy to see that k is a period of U if and only if the prex B of U of length n k is a border of U or is empty. Let (U) denote the smallest period …
