1. 1. Improving Software Quality through Understanding and Early Estimations

   Författare :Anders Wesslén; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Software Process; process improvement; software development process; defects; faults; failures; test planning; early estimations; usage profile; usage model; statistical usage testing; Software quality; software reliability; Systems engineering; computer technology; Data- och systemvetenskap;

   Sammanfattning : Software quality is an important factor of a large and complex software system. Hence, there is a need for measuring and controlling quality. Software quality has, however, many different f actors and involves implicit expectations of the behaviour of the software. LÄS MER

3. 2. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware

   Författare :Tahir Naseer Qureshi; Martin Törngren; DeJiu Chen; Ivica Crnkovic; KTH; []
   Nyckelord :Dynamic Reconfiguration; DySCAS; Self-Managing Systems; Load Balancing; Quality of Service QoS ; Model-Based Development; Modeling; Simulation; Model Transformation; Middleware; Embedded Systems; Component Based Design; Unified Modeling Language UML™ ; Discrete Event Systems; Real-Time Systems; Software Architecture; Simulink®; SimEvents™; Distributed Systems.;

   Sammanfattning : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. LÄS MER

4. 3. A Model for Simulation of Fiber Suspension Flows

   Författare :David Hammarström; KTH; []
   Nyckelord :rheology; fiber; suspension; CFD; model; wall; slip; turbulence;

   Sammanfattning : The fiber suspensions in the production line from wood topaper are subjected to many types of chemical and mechanicalprocesses, in which the flow of the suspension is of vitalimportance. The flow of the suspension determines the degree ofuniformity of the fibers through the processing, which inreturn affects the properties of the fiber suspension. LÄS MER

5. 4. Models for Estimation of Software Faults and Failures in Inspection and Test

   Författare :Per Runeson; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failures; usage based testing; usage model; statistical testing; faults; capture-recapture; inspections; software quality; software reliability; experiments; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Sammanfattning : In software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. LÄS MER

7. 5. Software Investments under Uncertainty : Modeling Intangible Consequences as a Stochastic Process

   Författare :Emil Numminen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software investment valuation; usage; intangible consequences; cash flow; discounted cash flow model; stochastic process;

   Sammanfattning : Software systems are today a part of more or less every organization. The varieties of software used in organizations are ranging from simple log-keeping applications to advanced decision support systems. The task of a priori valuation of software investments has attracted a lot of research for a long time. LÄS MER
