Putting documents into their work context in document analysis
2000
In trying to achieve document standardization the goal is to find more effective, consistent, and standardized ways to utilize information technology. The specification and implementation of document standards may take several years requiring a profound analysis and understanding of document management practices. Document standardization does not concern documents only: it concerns workers, their work, business partners, and future systems as well. In this paper we discuss two ways of describing the work context of documents: process modelling and life cycle modelling. In process modelling, documents are regarded as resources produced and used in inter- or intra-organizational business proc…
The role of standard software packages in mediating management accounting knowledge
2006
PurposeThis paper aims to analyse how cost accounting knowledge is mediated in a large multinational organisation employing a company‐wide enterprise resource planning system and off‐the‐shelf activity based costing software to create a uniform profitability management system within the organisation.Design/methodology/approachThe case analysis is informed by the theoretical notions of dis‐and re‐embedding of expert knowledge, expert systems and standards.FindingsThe results indicate that standardised cost accounting software packages may be useful not only because of their superior data processing properties and technical efficiency, but also because of their usability in overcoming resista…
Perceived Product Risk while Shopping Online: Does Virtual Reality vs. 2D Reduce Uncertainty?
2019
This research explores if a virtual reality (VR) vs. a 2D display of an online shop reduces the perceived product risk. Thereby the role of the sense of presence (SoP) will be analyzed and whether the evocation of the SoP can be predicted by the possibility to interact with the virtual environment as well as by the social connectivity with a friend while shopping online. The results of three empirical studies affirm the importance of a VR display to reduce uncertainties regarding the products in online shops and outline techniques how to trigger the SoP.
Method for Estimating the Manual Nesting Process Efficiency for Profiling Machines, Based upon Image Processing Techniques
2015
The paper presents a method for estimating the efficiency of the manual nesting process. By using the graphic file generated during the nesting process and using image processing techniques, the method allows the user to calculate the percentage of material used for manufacturing the parts. The method combines a manual approach - the user has to select some specific points on the graphic file with the mouse, with some image processing algorithms form Matlab software package.
Run-time profiling of functional logic programs
2005
In this work, we introduce a profiling scheme for modern functional logic languages covering notions like laziness, sharing, and non-determinism. Firstly, we instrument a natural (big-step) semantics in order to associate a symbolic cost to each basic operation (e.g., variable updates, function unfoldings, case evaluations). While this cost semantics provides a formal basis to analyze the cost of a computation, the implementation of a cost-augmented interpreter based on it would introduce a huge overhead. Therefore, we also introduce a sound transformation that instruments a program such that its execution—under the standard semantics—yields not only the corresponding results but also the a…
An adaptive approach to learning the preferences of users in a social network using weak estimators
2012
Published version of an article in the journal: Journal of Information Processing Systems. Also available from the publisher at: http://dx.doi.org/10.3745/JIPS.2012.8.2.191 - Open Access Since a social network by definition is so diverse, the problem of estimating the preferences of its users is becoming increasingly essential for personalized applications, which range from service recommender systems to the targeted advertising of services. However, unlike traditional estimation problems where the underlying target distribution is stationary; estimating a user's interests typically involves non-stationary distributions. The consequent time varying nature of the distribution to be tracked i…
Usefulness of an Internet-based thematic learning network: comparison of effectiveness with traditional teaching.
2006
UniNet is an Internet-based thematic network for a virtual community of users (VCU). It supports one multidisciplinary community of doctoral students, who receive most of the courses on the network. The evident advantages of distance learning by Internet, in terms of costs, comfort, etc., require a previous evaluation of the system, focusing on the learning outcomes of the student. The aim was to evaluate the real learning of the students of doctorate courses, by comparing the effectiveness of distance learning in UniNet with traditional classroom-based teaching. Five doctorate courses were taught simultaneously to two independent groups of students in two ways: one, through the UniNet Netw…
And Now for Something Completely Different: Running Lisp on GPUs
2018
The internal parallelism of compute resources increases permanently, and graphics processing units (GPUs) and other accelerators have been gaining importance in many domains. Researchers from life science, bioinformatics or artificial intelligence, for example, use GPUs to accelerate their computations. However, languages typically used in some of these disciplines often do not benefit from the technical developments because they cannot be executed natively on GPUs. Instead existing programs must be rewritten in other, less dynamic programming languages. On the other hand, the gap in programming features between accelerators and common CPUs shrinks permanently. Since accelerators are becomi…
DEXML: A First Step Toward a UML Based Implementation Framework for PLCS
2011
Data exchange specifications not only must be broad and general to achieve acceptance, but also must be customizable in a controlled and interoperable manner to be useful. The Product Life Cycle Support (PLCS) suite of data exchange specifications (known as DEXs) uses templates to enable controlled customizability without sacrificing breadth or interoperability. DEXs are business context-specific subsets of ISO 10303 Application Protocol (AP) 239, subject to additional constraints imposed by the templates. A PLCS template defines how AP239 entities and their attributes will be instantiated using an externally-defined controlled vocabulary defined in a Reference Data Library. Template instan…
XML Integration and Toolkit for B2B Applications
2003
This paper presents a Web-based data integration methodology and tool framework, called X-TIME, for the development of business-to-business (B2B) design environments and applications. X-TIME provides a data model translator toolkit based on an extensible metamodel and XML. It allows the creation of adaptable semantics oriented metamodels to facilitate the design of wrappers or reconciliators (mediators) by taking into account several characteristics of interoperable information systems such as extensibility and composability. X-TIME defines a set of meta-types for representing meta-level semantic descriptors of data models found in the Web. The meta-types are organized in a generalization h…
