1. 1. Performance and availability trade-offs in fault-tolerant middleware

   Författare :Diana Szentiványi; Simin Nadjm-Tehrani; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Programming; Distributed systems; fault tolerance; middleware; COBRA; code supporting; Computer science; Datavetenskap;

   Sammanfattning : Distributing functionality of an application is in common use. Systems that are built with this feature in mind also have to provide high levels of dependability. One way of assuring availability of services is to tolerate faults in the system, thereby avoiding failures. Building distributed applications is not an easy task. 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. Adaptive Middleware for Self-Configurable Embedded Real-Time Systems : Experiences from the DySCAS Project and Remaining Challenges

   Författare :Magnus Persson; Martin Törngren; DeJiu Chen; Thiemo Voigt; KTH; []
   Nyckelord :adaptivity; embedded real-time systems; DySCAS; DyLite; quality of service QoS ; load balancing; resource constraints; model-based design; component-based design; software architecture; adaptive middleware;

   Sammanfattning : Development of software for embedded real-time systems poses severalchallenges. Hard and soft constraints on timing, and usually considerableresource limitations, put important constraints on the development. Thetraditional way of coping with these issues is to produce a fully static design,i.e. LÄS MER

5. 4. Extending a networked robot system to include humans, tiny devices, and everyday objects

   Författare :Md. Jayedur Rashid; Mathias Broxvall; Alessandro Saffiotti; Thomas Pederson; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Networked Robot System NRS ; Ecology of Physically Embedded Intellignet Systems; Middleware; Tiny Embedded devices; Network of distributed ubiquitous sensors and actuators; Object proxies; human proxie; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : In networked robot systems (NRS), robots and robotic devices are distributed in the environment; typically tasks are performed by cooperation and coordination of such multiple networked components. NRS offer advantages over monolithic systems in terms of modularity, flexibility and cost effectiveness, and they are thus becoming a mainstream approach to the inclusion of robotic solutions in everyday environments.

7. 5. Inverted GUI Development for IoT with Applications in E-Health

   Författare :Björn A Johnsson; Institutionen för datavetenskap; []
   Nyckelord :Graphical user interfaces; GUI; Development tools; Internet of Things; IoT; E-health; End-user composition; Mobile applications; Android; PalCom; Middleware;

   Sammanfattning : In the context of Internet of Things (IoT), the research of this dissertation is concerned with the development of applications for end-user devices, i.e. devices through which the end-user directly interacts with systems. LÄS MER
