Dynamic Programming

Yohannes, Arega W. 01 May 1981 (has links)
The fundamental goal, in preparing this thesis, is two-fold. First, the author shows the systematic development of the basic theory of Dynamic Programming. Secondly, the author demonstrates the applicability of this theory in the actual problem solving of Dynamic Programming. A very careful balance has been maintained in the setting of the theory and in its applicability of solving problems. Basic theory has been established and expanded systematically and explained vividly. However, it is short and precise. Nevertheless, it presents the tools to handle highly complex problems in Dynamic Programming. Also, the theory is used to prove a general case of an N-stage optimization which demonstrates the sufficiency and capability of the theory.

docMD: Document Mediated Delivery : Bringing Electronic Document Delivery to Small Hospital Libraries

Schnell, Eric H. 09 1900 (has links)
Many small and rural hospital libraries lack the resources required to create services which allow the delivery of documents to their customers in electronic format. Such hospitals share common barriers from small staffs to network firewalls to computer support personnel which prevent the implementation of Internet Document Delivery (IDD) systems required for such services. The docMD project explores creating electronic document delivery services for 12 small and rural hospitals using a centralized service center model. Documents requested through DOCLINE, and which are filled through IDD software, are sent to the central site. Documents are converted into PDF format and placed on a web server. An email alert is sent to the customer indicating a documentâ s availability for download. Project libraries are not required to purchase, install, or maintain any computer hardware. No additional hospital library staff is needed. Documents are sent using the web and are passed through network firewalls. This paper provides a project overview, describes the model, and discusses outcomes. The docMD project is funded through the National Network of Libraries of Medicine, Greater Midwest Region

Interface to classification: some objectives and options

Slavic, Aida January 2006 (has links)
This is a preprint to be published in the Extensions & Corrections to the UDC. The paper explains the basic functions of browsing and searching that need to be supported in relation to analytico-synthetic classifications such as Universal Decimal Classification (UDC), irrespective of any specific, real-life implementation. UDC is an example of a semi-faceted system that can be used, for instance, for both post-coordinate searching and hierarchical/facet browsing. The advantages of using a classification for IR, however, depend on the strength of the GUI, which should provide a user-friendly interface to classification browsing and searching. The power of this interface is in supporting visualisation that will 'convert' what is potentially a user-unfriendly indexing language based on symbols, to a subject presentation that is easy to understand, search and navigate. A summary of the basic functions of searching and browsing a classification that may be provided on a user-friendly interface is given and examples of classification browsing interfaces are provided.

Information systems - informing systems. Keynote presentation given at 5th CONTECSI 2008, São Paulo, June 5 9.00-10.30

Hjørland, Birger 05 1900 (has links)
This presentation considers some basic theoretical issues concerning information systems. Theoretical and conceptual issues are seen as important, although difficult, neglected and perhaps somewhat disappointing in the short run. An analysis of the concept "information" demonstrates that anything can be information. But if anything is information, what then is the content of information systems? What principles guide the selection of "information". If information is understood as something that informs somebody about something, it follows that information systems should be understood as informing systems. Information systems are teleological (goal directed) systems in which the intention and goals behind the systems determine what to consider information, how informative objects should be selected, labeled, described, organized and retrieved. (as opposed to "objective" or "universal" criteria governing these processes). Theory in relation to information systems spans several levels: 1) The theory of information science and information systems, 2) the theory of the contents in information systems ("information" or "knowledge", i.e. the theory of knowledge), 3) the nature of users (cognition) and 4) the theory of languages and symbolic systems used by cultures, communities and domains. Basically are the theories governing all layers influenced by epistemological views (often unconsciously). The epistemological theories are thus seen as fundamental for all levels. There are many theories of knowledge and the point is, of course, that it is important for information science and information systems research to be based on the most fruitful one. By implication it is important for us to defend a specific epistemology on which to base our work. My recommendation is "pragmatism" understood broadly and in contrast to other views such as empiricism, rationalism and positivism. Pragmatism is related to historicism but emphasizes the study of goals, values and consequences, which is important given the teleological nature of information systems. The pragmatic understanding of information systems, the knowledge represented in the information systems, the users and the languages is consequently outlined and implications for information systems design is proposed.

Locating Library Items by GIS Technology

Xia, Jingfeng January 2005 (has links)
This article identifies a common problem in many academic libraries: users having difficulties finding library items. It suggests that a mapping system may help solve the problem if the difficulties stem from users who do not understand floor structures of the library or classification of the collections. The technology of Geographic Information Systems (GIS) is proposed to build the system because of its ability to analyze spatial data of collection locations and dynamically present the analytical results in maps of varied detail. Such a GIS item-locating system could be integrated into current online catalog systems so that users would have search results in both textual display and visual demonstration. The article advocates that libraries take advantages of GIS for its inexpensive development and simple implementation.

What can ICTs do? Perpsectives from the developing world

Arunachalam, Subbiah January 2006 (has links)
This chapter is from an invited presentation (15 pages long) given at the Aachen Colloquium on Click - A Split World, November 2004. It has appeared in the book [Gespaltene Welt? Technikzugange in der Wissensgesellschaft, edited by Max Kerner and Thomas Muller, and published by Bohlau Verlag, Koln, 2006] and is the author's final version. Introduction: I am asked to reflect on social and cultural consequences of technical development and try to answer a few questions: â ¢ In what different kind of ways access to knowledge is modified in an information technology-based society that is dominated by technical resources? â ¢ Does global exchange of information enable ubiquitous access to knowledge? â ¢ By which means do information technologies contribute to the solution or intensify global and local problems? â ¢ Which requirements arise from this problem for an IT-based society? I shall try to answer these questions from the point of view of a Third Worlder. Most other speakers at this colloquium are thinkers and experts known for their scholarship and academic achievements. I do not belong to the same league. I am not saying this out of humility; I am making a statement of fact. Then why am I here? Because I have felt the impact of information and communication technologies (ICTs) on the developing world and I have been working for many years to overcome the 1 deleterious consequences of ICTs in the context of the poor and the marginalized. I wish to share with you what I have learnt through working in the field. I am coming from India where we had a major election a few months ago. We are happy about the election for two reasons. One, contrary to what is happening in many parts of the developing world, democracy in India is vibrant and we have been holding free and fair elections consistently for more than 50 years. Two, despite outstanding achievements in the areas of high technology in general and information and communication technologies (ICTs) in particular, the ruling governments in the states of Karnataka and Andhra Pradesh belonging to two different parties have failed to return to power, largely because the rural poor voted against them. Thanks to rapid developments in indigenous capabilities combined with favorable policies by the governments in these two southern states of India, a number of IT industries and research laboratories â both Indian and multinational â sprung up, mainly in the capital cities Bangalore (referred to as the Silicon Valley of the East) and Hyderabad (half jocularly called Cyberabad). But these developments did not have a perceptible impact on the rural poor, who felt that they were neglected. What can information and communication technologies (ICTs) do to help the poor? Can they do anything at all? That is a question that dominates the development discourse. If poverty has been so persistent that we could not eliminate it with all our efforts till now, how can the use of ICTs make a difference? Poverty is much more than absence of money. Often generations in poverty lead people to a sense of utter hopelessness and deprive them of their sense of self-respect and dignity. They are deprived of access to essential assets and opportunities such as education, healthcare, employment, land and other natural resources, services, infrastructure and credit. They have little say in their polity and society. They are not empowered to participate in making the decisions that shape their lives. They become increasingly marginalized, excluded and vulnerable to exploitation. This exploitation manifests in several forms such as bonded labour, child labour, inadequate compensation for work if and when they get work, ill treatment and deprivation of basic rights. It will be naïve to believe that we can solve the problem of poverty by providing access to computers and telecommunication to the poor of the world.1 We have always lived in an unequal world, but now the gap between information â havesâ and â have-notsâ is widening fast. As Kofi Annan2 has noted, â there is a real danger that the worldâ s poor will be excluded from the emerging knowledge-based 2 global economy.â Virtually every new technology tends to exacerbate the inequalities that separate the rich from the poor. The last few years have seen many initiatives that deploy ICTs in rural communities in many developing countries. Many world leaders have spoken in glorious terms about the tremendous potential of these new technologies in transforming the lives of the poor. â Technology doesnâ t come after you deal with poverty, but is a tool you use to alleviate poverty,â says James D Wolfensohn, President of the World Bank. Says Mark Malloch Brown, Head of UNDP, â ICTs can help us reach the Millennium Development Goals including the goal of halving poverty by 2015.â It is mastery over technology that enabled the early adopters of industrial revolution technologies to colonize and exploit the rest of the world. If the developing countries fail to take advantage of the new ICTs, the consequences could be far more serious. If we want technology to work for the poor we must make special efforts. In this talk I will describe from my own personal experience two widely different programmes where we are attempting to bridge the gulf that divides the rich from the poor through innovative use of information and communication technologies. In the first part of my talk we will look at how we at the M S Swaminathan Research Foundation (MSSRF) are trying to harness ICTs as part of a holistic strategy for alleviating poverty in rural India. I will show why the emphasis should be on people and the public commons approach rather than on technology. In the second part, we will look at how the advent of new technologies has opened up the possibility for making knowledge distribution in science and scholarship a level-playing field. Here again the public commons approach is the key to success.

Fostering Technical Innovation in Libraries

Bailey, Charles W. January 1992 (has links)
Grant funding offers one way to foster innovation, and, for large-scale projects, it may be essential; however, there are limited opportunities to secure such funding and many small projects may not warrant it. When grant funding is sought, the library's proposal is strengthened if it can demonstrate prior effort and expertise in the proposal area. Every opportunity to secure grant funding should be seized; however, libraries should not limit themselves to this funding option. This paper provides some brief guidelines for encouraging technical innovation without depending on grant funding.

Relevance and Success of IS Teaching and Research: An Analysis of the "Relevance Debate"

Schauer, Carola January 2007 (has links)
This report is part of a series of publications on the status and development of the North-American Information Systems (IS) field and Wirtschaftsinformatik (WI), its counterpart in German speaking countries. Information systems in businesses and organizations are the main subject of research in IS and WI. Hence, both disciplines are applied fields of research. Thus, the valuation of research results and graduates by business practice are vital indicators for the disciplinesâ status and success. Between 1991 and 2001 a plethora of articles were published in leading Information Systems (IS) journals and conference proceedings addressing the issue of relevance of IS research and teaching. This research report provides a comprehensive content analysis of this â relevance debateâ in the North-American Information Systems field. The perceptions, opinions, and recommendations of the contributors are presented structured according to statements of valuation, perception, explanation, and recommendation. The reconstruction of the main IS relevance debate indicates that all debate participants agree that relevance to practice plays a vital role for the IS discipline, but that the field largely lacks relevance in terms of research as well as in terms of teaching. The lack of relevance is, for example, illustrated by the general perception that research results rarely impact practice and that IT/IS professionals usually do not read academic IS journals. In order to analyse if the debate has lead to any changes in terms of practice relevance of the IS field the most recent literature and studies available on IS relevance are evaluated. Analysis results indicate that no significant changes took place. But various IS researchers still report on problems in terms of acceptance and perception of IS degree programs and research. Based on the perspectives of experienced researchers from WI and other European IS communities the concluding remarks of this report attempt to explain the apparent lack of change in the North-American IS field and provide suggestions for improving the current status of the IS field in terms of relevance.
