In terms of a concrete example we derive a greedy algorithm for a hard problem. Recently, the Lambda Calculus and related systems acquire attention from Computer Science for another reason too: The valorisation indicators presented by the University of Twente relate to: Apart from the technical aspects, we show that personalizing the policies introduces some inference breaches which have to be further investigated. Unpublished Technical Report, 10 pages.

Finally we will use these extensions in a newsgroup example, to illustrate DXL’s main features, with respect to querying heterogeneous sources, and its recursive behavior. The existence of such an interpretation is important, because it enables us to decide various questions about the notation without resorting to informal hence subjective arguments. Geen enkele van de twintig studenten had een volledig correcte uitwerking. We attempt to characterize the goals that we have in mind when formalizing the relation between distributed XML query processing and integration. In contrast we use the word count specification to derive the intended word count algorithm.

In this report, we recall the formerly introduced life cycle policy model and the already developed techniques for handling a single collective policy for all data in a relational database management system.

The board members and the founders regularly meet to discuss the progress based on the metrics in the annual plan. The example is the case of two thermometers, with possibly different scales Centigrades, Fahrenheit, or whateverthat can be used separately but also in a coupling in such a way that the coupled pair behaves consistently.

Dat doen we door eerst van de klassieke gegevensbanken een voorbeeld te geven, dan aan de hand van dat zelfde voorbeeld probabilistische gegevensbanken te definieren, en tenslotte wat toepassingen het nut ervan te laten zien. Inand the university was awarded the prize of most entrepreneurial university in the Netherlands.


PhD thesis completed in June 4,on the topic of privacy protection, resulting in the method of progressive data degradation which decreases the risk for privacy violation when data unintendedly gets disclosed and techniques to implement this method efficiently in a database system.

This composability provides a theoretical basis for building scalable and flexible models for sensor data. Het systeem is zelflerend, zodat het smaakprofiel van de gebruiker met het utweente van de tijd steeds beter wordt. In this paper tyesis address the task of automatically finding an expert within the organization, known as the expert search problem.

ISSN11 pages. This is a summary of the paper by Ceri and Widom, rephrased on a very abstract level and provided with alternative and simpler proofs.

As agreed in a General Agreement signed in between the Ministry of Education and the Dutch university sector, the universities started working on developing and using valorisation indicators.

We show this mainly by means of examples. More particularly, the board of thesjs Foundation Kennispark Twente is held accountable to its five founding institutions as external investors: In the first of these, the organizational structure and some key characteristics of the university are presented.

We recommend the approach in the teaching of SQL, observe the possibility of tools assistance, and call for future work to build tools that support the approach. This shows that entrepreneurship is very much on the rise in the university.

Another way of knowledge transfer is the delivery of graduates to society. One application of DXL, the focus in this article, is to retrieve data from databases and yield the result in XML documents. Queries over these databases result in probabilistic answers. Unpublished Technical Report, 16 pages.

PhD thesis completed in June 2,resulting in scalability in querying huge utqente of complexly structured data, by means of a way to transform item-at-a-time processing into bulk processing. We show how to adapt the semantics S in a simple set theoretic way, obtaining a semantics S’ uh satisfies, in addition to some obvious requirements, also the property that: This report proposes Dodo, an approach to automatic translation of queries from the complex objects domain into set-at-a-time operations against data stored in a flattened form.


In Chapter 5 a category theoretic formalisation of the notion of law itself is derived and investigated. For these operators we derive various algebraic laws that are useful in deriving and manipulating programs. From expertise identification to expertise selection. A transformer is a special kind of functor and also a natural transformation on the level of dialgebras. Fokkinga, Aggregation polymorphic and polytypic. This paper presents a framework to an- alyze the alignment problem and operationalizes this as an approach to application architecture design given a business context.

Thesis overview

The results are relevant for current functional programming languages. I focus on technical aspects, omitting all system names and references. It supplies research and human capital to local companies, accommodates hundreds of enterprises, and plays a key role in new venture creation.

As a show of what I have learned from Lambert and maybe of what I still have to learn I will discuss a generalisation of the elimination of left-nesting in full.

We introduce two variants on the Hidden Markov Model in which this is possible:
