Study on Service-Oriented Cable TV Customer Business Management ModelChen, Ming-yuan 28 January 2010 (has links)
The current international standard ISO quality management practices and process-oriented methods widely used in various internal management and supervision, but businesses in dealing with the rapidly changing external environment, information technology can bring knowledge and complexity, as well as the effective use of corporate resources can be fully and so forth, these important issues can not be resolved through the above methods. The proverb says: You can manage what can not measure. The proverb also says: You can not measure what you can not describe. Therefore, enterprises need a clear and concise method for describing their overall business operations. It is even better that this method owns the flexibility to flexible and easy to learn and other features, so as to ensure sustainable development of the business.
This study investigated Service-Oriented Cable TV Customer Business Management Model (SOCTCBMM). SOCTCBMM most salient feature is a service (structure elements) to guide a behavior, resulting in structure-behavior coalescence (SBC) of effect. In other words, Service-Oriented Cable TV Customer Business Management Model uses structure view as an entry point, so the basic unit of SOCTCBMM is a service, differing from process-oriented methods which use behavior view as an entry point. This research concluded that: the SBC service-oriented approach clearly and concisely describes the overall business operations, and therefore it is the enterprise the best options, it is not an exaggeration.

Recognizing human activities from low-resolution videosChen, Chia-Chih, 1979- 01 February 2012 (has links)
Human activity recognition is one of the intensively studied areas in computer vision. Most existing works do not assume video resolution to be a problem due to general applications of interests. However, with continuous concerns about global security and emerging needs for intelligent video analysis tools, activity recognition from low-resolution and low-quality videos has become a crucial topic for further research. In this dissertation, We present a series of approaches which are developed specifically to address the related issues regarding low-level image preprocessing, single person activity recognition, and human-vehicle interaction reasoning from low-resolution surveillance videos.
Human cast shadows are one of the major issues which adversely effect the performance of an activity recognition system. This is because human shadow direction varies depending on the time of the day and the date of the year. To better resolve this problem, we propose a shadow removal technique which effectively eliminates a human shadow cast from a light source of unknown direction. A multi-cue shadow descriptor is employed to characterize the distinctive properties of shadows. Our approach detects, segments, and then removes shadows.
We propose two different methods to recognize single person actions and activities from low-resolution surveillance videos. The first approach adopts a joint feature histogram based representation, which is the concatenation of subspace projected gradient and optical flow features in time. However, in this problem, the use of low-resolution, coarse, pixel-level features alone limits the recognition accuracy. Therefore, in the second work, we contributed a novel mid-level descriptor, which converts an activity sequence into simultaneous temporal signals at body parts. With our representation, activities are recognized through both the local video content and the short-time spectral properties of body parts' movements. We draw the analogies between activity and speech recognition and show that our speech-like representation and recognition scheme improves recognition performance in several low-resolution datasets.
To complete the research on this subject, we also tackle the challenging problem of recognizing human-vehicle interactions from low-resolution aerial videos. We present a temporal logic based approach which does not require training from event examples. At the low-level, we employ dynamic programming to perform fast model fitting between
the tracked vehicle and the rendered 3-D vehicle models. At the semantic-level, given the localized event region of interest (ROI), we verify the time series of human-vehicle spatial relationships with the pre-specified event definitions in a piecewise fashion. Our framework can be generalized to recognize any type of human-vehicle interaction from aerial videos. / text

En kvalitativ studie om förskollärares förhållningssätt till barnen och kunskapande : En jämförande studie mellan en Reggio Emilia förskola och en traditionell förskolaHernandez, Karolina January 2011 (has links)
The purpose of this study is to determine which approach preschool teachers from a Reggio Emilia inspired preschool and a traditional preschool have on children, knowledge, learning and their own role in children’s learning. The two pedagogical approaches have different basic visions; Reggio Emilia follows the thoughts of Lori Malaguzzi and the traditional preschool follows the Swedish curriculum Lpfö 98. The main research questions asked were: What view on children, learning and knowledge does the preschool teacher from a Reggio Emilia inspired preschool have in comparison with a traditional preschool? Which role does the teacher believe that they should take regarding children’s learning? What differences and similarities can be identified in the teachers' perceptions? To carry out this study, I used a qualitative research method. I interviewed four preschool teachers, two from a Reggio Emilia inspired preschool and two from a traditionally operated preschool. The teachers’ approaches have been analyzed by a social constructionist view on the child, knowledge building, learning and the teacher's role. Dewey, Vygotskij and Freinet are the main theoreticians of the view on children and knowledge. Meanwhile modern researchers account for the theory regarding the role of teachers and the educational environment. The result of the study showed that all teachers had the same approach regarding children, knowledge, learning and their own role. My conclusion is that teachers' attitude permeates all activities and that it affects children's learning in the end. Although the pre-schools were conducted with different pedagogical approaches, this study revealed that there were no differences in teachers' ways of looking at the children, knowledge, learning and their own role in children’s learning.

Automatic juxtaposition of source filesDavis, Samuel 11 1900 (has links)
Previous research has found that programmers spend a significant fraction of their time navigating between different source code locations and that much of that time is spent returning to previously viewed code. Other work has identified the ability to juxtapose arbitrary pieces of code as cognitively important. However, modern IDEs have inherited a user interface design in which, usually, only one source file is displayed at a time, with the result that users must switch back and forth from one file to another.
Taking advantage of the increasing availability of large displays, we propose a new interaction paradigm in which an IDE presents parts of multiple source files side by side, using the Mylyn degree-of-interest function to dynamically allocate screen space to them on the basis of degree-of-interest to the current development task. We demonstrate the feasibility of this paradigm with a prototype implementation built on the Eclipse IDE and note that it was used by the author over a period of months in the development of the prototype itself. Additionally, we present two case studies which quantify the potential reduction in navigation and demonstrate the simplicity of the approach and its ability to capture complete concerns on screen. These case studies suggest that the approach has the potential to reduce the time that programmers spend navigating by as much as 50%.

Master Texture Space: An Efficient Encoding for Projectively Mapped ObjectsGuinnip, David 01 January 2005 (has links)
Projectively textured models are used in an increasingly large number of applicationsthat dynamically combine images with a simple geometric surface in a viewpoint dependentway. These models can provide visual fidelity while retaining the effects affordedby geometric approximation such as shadow casting and accurate perspective distortion.However, the number of stored views can be quite large and novel views must be synthesizedduring the rendering process because no single view may correctly texture the entireobject surface. This work introduces the Master Texture encoding and demonstrates thatthe encoding increases the utility of projectively textured objects by reducing render-timeoperations. Encoding involves three steps; 1) all image regions that correspond to the samegeometric mesh element are extracted and warped to a facet of uniform size and shape,2) an efficient packing of these facets into a new Master Texture image is computed, and3) the visibility of each pixel in the new Master Texture data is guaranteed using a simplealgorithm to discard occluded pixels in each view. Because the encoding implicitly representsthe multi-view geometry of the multiple images, a single texture mesh is sufficientto render the view-dependent model. More importantly, every Master Texture image cancorrectly texture the entire surface of the object, removing expensive computations suchas visibility analysis from the rendering algorithm. A benefit of this encoding is the supportfor pixel-wise view synthesis. The utility of pixel-wise view synthesis is demonstratedwith a real-time Master Texture encoded VDTM application. Pixel-wise synthesis is alsodemonstrated with an algorithm that distills a set of Master Texture images to a singleview-independent Master Texture image.

Influencing Factors on the Selection Process of Enterprise System(s) : A study on the client and vendor perspectivesHossain, Mohammad, Cao, Shuang January 2005 (has links)
Enterprise system (ES) is being considered an important phenomenon in the corporate use of information technology, enhancing organizational cross functional efficiency and effectiveness through the integration of all the information flowing through a company. The implementation and use of this system involve high expenditure and risk and it has a great impact in every aspect of an adopting organization. The wrong selection of this system would have an adverse effect on the company performance. So the selection of this system deserves considerable attention from the practitioner and researcher. In this study, our objective is to identify the influencing factors on the ES selection process from the existing theory and investigate them in real life situation from the client and vendor’s perspectives. To fulfil the first objective of the study, we have made a comprehensive review on ES literature and synthesized an integrated framework of influencing factors on the ES selection process. To fulfil the other objective, we have made a qualitative empirical study through multiple case study approach. To collect necessary in-depth information, we have used purposive sampling and general interview guide approach. The integrated framework has guided us in empirical study and the cross case analysis of empirical data has been performed on the basis of this framework from the view point of client and vendor. The result of this study shows that there exists a good fit between client and vendor views about the influencing factors on the ES selection process, in spite of insignificant imbalance between them. The result also reveals that most of the influencing factors of integrated framework have been recognized both by client and vendor with some diversity. Three new influencing factors: geographical proximity, requirement specification and sales skill of vendor have emerged from the study.

Information systems evaluation : a post-dualist interpretationWhittaker, Louise 14 June 2002 (has links)
This thesis explores the problem of information systems evaluation by conceptualising it as a process in which the manager comes to an understanding about a system. In other words, information systems evaluation is a hermeneutic process. The thesis explicates this notion through an argument that is itself hermeneutic in its development, beginning with the mainstream functionalist view of information systems evaluation, and then considering an interpretive view of IS evaluation, each of which points to one of two stereotypes of IS evaluation and the manager engaged in this process: the objective/rational manager utilising objective/rational methods versus the subjective/political manager engaged in political manoeuvring, utilising objective/rational methods only as ritual or symbolism. Neither of these opposing stereotypes is satisfactory. Instead, this thesis proposes a dialectic view of information systems evaluation, in terms of which, rather than being a decision maker, the manager is in-the-world, evaluating systems in order to get the job done, on the basis of her thrownness in-the-world. This conceptualisation provides an intuitively appropriate account of evaluation on the part of an individual manager, but we must still consider how managers as members of the organisation, reach a common understanding about a system. This they do through a process of organisational learning as encultured knowing, in terms of which a narrative, situated, pragmatic knowledge is most useful in evaluation. Evaluation, in other words, happens in the course of skilful conversation. Such conversation is, however, not always skilful because the organisation is not just a collection of individuals but also a network of power relations. Conversations as generators of meaning are never held outside of power: systems evaluations as conversations cannot take place outside of a regime of truth. A post-dualist view of action as both constituted by and constituting structure, however, suggests that there is always the potential for genuinely hermeneutic and ethical conversation, provided it is both improvisatory and deconstructive. Having understood the requirement for improvisation and deconstruction, it is possible to suggest some heuristics for information systems evaluation based on these ideas. / Dissertation (Phd (Information Technology))--University of Pretoria, 2003. / Informatics / unrestricted

The Influence of Stakeholders on the Sustainable Development of the Wind Power Industry in Canada: The Firm’s PerspectiveMoularé, Éboua Yves Éric Didier January 2016 (has links)
We propose making an empirical application of the temporal view of stakeholder management theory by applying it in the particular context of the Canadian wind industry. The temporal view builds on insights from the resource-based view (RBV), institutional theory, and stakeholder salience theory. We argue that both early stage competitive advantage and late stage sustained competitive advantage could be dependent on the use of salient stakeholders as a special network of resources. We contribute to the literature in various ways. First we determine an empirical list of five salient stakeholders specific to the wind industry. Second, we show that, at early stages, the moderating effects of firm size and market conditions determines stakeholder support or rejection. Lastly, we show that, at late stages, the sustainability equation must take into account the introduction of new salient stakeholders. Also, we make practical recommendations for industry players and policy makers. We reached theory refinement by adopting an exploratory qualitative methodology based on interviews with seven cases of large and small wind firms operating in different electricity market types and provinces across Canada.
