En inter-organisatorisk förändringsanalys : utveckling av kund-/leverantörsprocessen
- 1997
-
Konferensbidrag (refereegranskat)abstract
- Dagens sätt att göra affärer innebär ett ökat partnerskap och ett ökat datautbyte mellan organisationer i sökandet efter effektivitet och konkurrensfördelar. Affärsrelationer mellan leverantörer och kunder är beroende av att informationen flödar på ett strukturerat sätt mellan deras organisationer för att tillgodose respektive parts informationsbehov, dvs inter-organisatoriska informationssystem (IOIS). En metodutveckling pågår inom VINST-projektet där målet är att utveckla kunskap om och utforma en användbar metod som stöd vid verksamhetsutveckling av inter-organisatorisk karaktär. Denna rapport bygger på en metodprövande aktionsforskning vid en gemensam förändringsanalys som PartnerTech AB och en av deras kunder bedrivit med stöd av FA/SIMMetoden. Den metodtillämpning och metodutveckling som skett analyseras och diskuteras utifrån frågorna; hur en leverantör tillsammans med kunden kan utveckla den gemensamma kund-leverantörsprocessen och hur verksamhetsutvecklare kan använda FA/SIMM för att kartlägga och driva förbättring av inter-organisatoriska processer. Rapporten pekar bl a på behov av anpassade projektstrategier, arbetsformer och notation samt metodkomponenter för interaktionsanalys och uppföljning av åtgärder.

PWLTool - a Matlab Toolbox for Piecewise Linear System
- 1999
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This manual describes a Matlab toolbox for computational analysis of piecewise linear systems. Key features of the toolbox are modeling, simulation, analysis, and optimal control for piecewise linear systems. The simulation routines detect sliding modes and simulate equivalent dynamics. The analysis and design are based on computation of piecewise quadratic Lyapunov functions. The computations are performed using convex optimization in terms of linear matrix inequalities (LMIs).

Social and Organizational Aspects of Requirements Engineering Methods
- 1999
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Improving requirements engineering has been recognized as critical for the 1990s. Reported differences in theoretical reasoning vs. the practice of how methods are used suggest a need for further research. A way to proceed is to investigate how real-life system design situations can be supported the best way. An important area is to investigate social and organizational aspects of the design of requirements engineering methods. Also increasing the knowledge of what is regarded as important by the users of methods for requirements engineering is essential for progress and development of new knowledge in the field.The aim of this thesis is to develop knowledge of what social and organizational issues are important for the use and development of requirements engineering methods. The research is based on a qualitative research approach using different qualitative methods and instruments for data gathering and data analysis.The results include an outline of a preliminary method for requirements engineering (Action Design). A "handbook evaluation" shows motives and needs for requirement engineering methods. Quality characteristics recognized in requirements engineering as important by the participants are established and prioritized. Thereafter, the value of visualization of internal functions for an enterprise in participatory design projects is presented. Finally, an integration of techniques for enterprise modeling and prioritization of requirements is performed to analyze what value such integration has and how improvements can be achieved.This research suggests an alternative approach to requirements engineering where support and methods are grounded in the prerequisites for each situation. The results are mainly applicable to situations where multiprofessional participation is desired. It is concluded that the organizational context has to be taken into account in the improvement of methods used in-requirements engineering.

High frequency losses in transmission lines made on SIMOX, bulk silicon and depleted silicon/silicon structures formed by wafer bonding
- 1999
-
Ingår i: 1999 IEEE International SOI Conference. Proceedings (Cat. No.99CH36345). ; , s. 30-
-
Konferensbidrag (refereegranskat)abstract
- Wafer bonding and etch-back has been used to manufacture a silicon material intended as substrate for high frequency applications. The space charge region surrounding the bonded silicon/silicon interface depletes the silicon, thereby causing semi-insulating behaviour at high frequencies. The formed material was characterized using measurements on metal transmission lines and the results were compared to similar measurements on SIMOX and bulk silicon wafers
