This thesis proposes some new iterative local modeling algorithms for the multivariate approximation problem (mapping from R P to R). Partial Least Squares Regression (PLS)is used as the local linear modeling technique. ...

Most research into persistent programming has been directed towards the design and implementation of languages and object stores. There are few reports on the characteristics of systems exploiting such technology. This ...

In medical ultrasound imaging, beam control methods such as dynamic focusing, and dynamic aperture and weighting give a need for more flexible control over the receive beam. In addition the desire to increase acquired ...

Certain deterministic non-linear systems may show chaotic behaviour. Time series derived from such systems seem stochastic when analyzed with linear techniques. However, uncovering the deterministic structure is important ...

The area and the perimeter of a planar object are two useful features to describe the shape of the object, and again the motion of it. This paper deals with the estimation of the two features from a discrete binary image. ...

Because of the close connection between computer systems and organizations, organizational aspects should be taught in system development courses. Dataflow diagramming is a frequently taught technique that can model formal ...

As application systems live longer and grow in size and complexity, there is an ever increasing need for methodologies, models and tools that can aid software builders in developing maintainable, correct and consistent ...

Persistent object systems are highly-valued technology because they o er an e ec- tive foundation for building very long-lived persistent application systems (PAS). The technology becomes more e ective as it o ers a more ...

Achieving correct changes is the dominant activity in the application software industry. Modification of database schemata is one kind of change which may have severe consequences for database applications. The paper ...

The major motivation for database programming language (DBPL) research is to facilitate the construction and maintenance of large dataintensive applications. To fully bene t from DBPLs, supporting methodologies and tools ...

Denne hovedfagsoppgaven tar for seg to forskjellige emner, begge relatert til dokumentproduksjonssystemet LATEX. Del I tar for seg virtuelle fonter, og del II tar for seg norsk orddeling. LATEX,som er et påbygg på TEX, ...

Målet med oppgaven var å undersøke hvordan fjernundervisning og datakonferansesystemer (DKS) kan kombineres, og danne et nytt fjernundervisningskonsept. Utfordringer her lå i å finne ut hvilke tilpasninger som bør gjøres ...

SYDPOL er et kunnskapsutviklingsprogram som baseres på nasjonalt prioriterte og finansierte utviklingsprosjekter. Deltakere er både forskere innen fagområdene systemutvikling, systemutviklingsomgivelser og dataspråk, innen ...

I made the first implementation and wrote the original MVC reports while I was a visiting scientist at Xerox Palo Alto Research Laboratory (PARC) in 1978/79. MVC was conceived as a general solution to the problem of users ...

The organisation of a yard may be strongly influenced by the information system it takes into use. The converse should also be true: Systems development should be subordinated the desired evolution of the organisation. The ...
