Several times we manage to present the proofs of an implication and its converse that use different induction hypotheses as one series of equivalences. Geen enkele van de twintig studenten had een volledig correcte uitwerking. Deze bundel van weinig tekst en veel opgaven is bedoeld als een eerste kennismaking met programmeren, aan de hand van een functionele programmertaal. It prescribes the use of a particular additional data structure for direct access to the locations where requested values have been stored. The techniques discussed are explained at length in a textbook by Wieringa. Creating spin-off and start-up companies is a key objective of the University of Twente.

Deze bundel van weinig tekst en veel opgaven is bedoeld als een eerste kennismaking met programmeren, aan de hand van een functionele programmertaal. Over the years, potential indicators for monitoring valorisation activity were proposed by several agencies e. We show how to translate these aspects in terms of conventional process constructs. To make such an investigation possible, we introduce a metric for privacy, which enables the possibility to compare the provided amount of privacy with the amount of privacy required by the policy. The Hough transform is a computerized procedure for that task. Het systeem is zelflerend, zodat het smaakprofiel van de gebruiker met het verloop van de tijd steeds beter wordt.

The UT offers a minor, six bachelor modules and three Master modules, often tailored utwrnte specific programs. When can a program part be replaced by another? All this is elegantly formalized in the Z notation. Dat idee willen we hier duidelijk maken. Patenting and invention disclosures and knowledge transfer in general constitute the fourth pillar of knowledge valorisation. The well-known notions of linear recursion and tail recursion are extended, for structures, to elementwise linear recursion and elementwise tail recursion; and a transformation between them is derived too.

Phrased in terms of category theory, these turn out to be dualizations of each other hence he speaks of SQL and coSQLand many of their properties are in some sense dual to each other.

It is a medium-sized university with a strong engineering core, next to a social sciences base. This indicates that ERDs are a concise notation; giving only the mathematical formulas instead of a graphical ERD would be unpractical.

PhD thesis completed in Sept 25,resulting in a method to derive algorithms for theis probabilistic processing “inference” in a mathematical rigorous way, which has been applied to achieve scalability with respect to the number of locations, the number of sensors, and the time interval in processing of sensor data. Geen enkele van de twintig studenten had een volledig correcte uitwerking.

One application of DXL, the focus in this article, is to retrieve data from databases, and yield the result in an XML document.

In Chapter 2 the systematic detection and use of laws is applied to category theory itself. We also propose a solution for privacy protection, which is urgently required in view of the huge amount of privacy sensitive data involved. We show how to adapt the semantics S in a simple set theoretic way, obtaining a semantics S’ that satisfies, in addition to some obvious requirements, also the property that: A transformer is a special kind of functor and also a natural transformation on the level of dialgebras.

Addison-Wesley, for calculating the total cost and amount of buffers of a query execution plan is elegant, clear, well-phrased, correct, instructive and so on, but does not take care of pipelining and the available buffers in a systematic way, and, instead, needs ad hoc reasoning for these aspects. We also abstract from the particulars of the concrete problem, uh formalize our greedy algorithm in a general and abstract setting.

We need to assume tuesis the base category is omega-cocomplete, and has all finite coequalisers, pushouts, and kernel pairs pullbacks of equal pairs ; the functor of the algebra has to be omega-cocontinuous. We describe what we think is the essence of Object-Orientedness OOand then show by means of an utwenre how this style translates into a Functional Programming FP notation.

As a show of what I have learned from Lambert and utwent of what I still have to learn I will discuss a generalisation of the elimination of left-nesting in full. The concrete problem is: A way to model Context-Aware Preferences.

The board members and the founders regularly meet to discuss the progress based on the metrics in the annual plan.

Measuring the Impact at the University of Twente

The goal of the university is to create between 30 and 60 start-ups per year of which 15 are spin-offs based on intellectual property IP coming from the University of Twente. The correctness and termination of a collection of rules follows from local correctness and termination properties for the individual rules, which are left to the responsibility of the user.

Current research uwtente architecture alignment is either too strategic or too software implementation-oriented to be of use to thesiw practicing information systems architect. Exploring personalized life cycle policies. The number of companies, however, is not registered so far. Furthermore, each refinement in bisimulation semantics implies its counterpart in failure semantics, and conversely each refinement in failure semantics implies its counterpart in bisimulation semantics defined on the canonical form of the compared processes.

However, after the year the number of start-ups and spin-offs levelled off thexis. The calculation is concise, machine checkable, and human readable at the same time.

Thesis overview

To better serve users’ information needs without requiring comprehensive queries from users, a simple yet effective technique is to explore the preferences of users. This is shown formally in a very general setting. Unpublished Technical Report, 4 pages.

However, in all cases there is room for qualitative information. Cardelli’s fundamental jtwente was a semantics for his system that enabled sub-typing to be modelled as straightforward set-inclusion.
