1. 16. Architectures and Protocols for Performance Improvements of Real-Time Networks

   Författare :Kristina Kunert; Magnus Jonsson; Elisabeth Uhlemann; Eduardo Tovar; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time communication; predictable deadline guarantees; real-time scheduling analysis; timing analysis; admission control; deterministic medium access; MAC; Quality of Service parameters; reliability; redundancy; retransmission scheme; ARQ; truncated ARQ; Automatic Repeat Request; wireless networks; IEEE 802.11; IEEE 802.15.4; fibre-optic networks; AWG; multichannel networks; industrial communications; embedded systems; Computer engineering; Datorteknik;

   Sammanfattning : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. LÄS MER

3. 17. On Real-Time Optimization using Extremum Seeking Control and Economic Model Predictive Control : With Applications to Bioreactors and Paper Machines

   Författare :Olle Trollberg; Elling Jacobsen; Sigurd Skogestad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Optimization; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Process optimization is used to improve the utility and the economic performance of industrial processes, and is as such central in most automation strategies. In this thesis, two feedback-based methods for online process optimization are considered: Extremum seeking control (ESC), a classic model-free method used for steady-state optimization which dates back to the early 1900's, and economic model predictive control (EMPC), a more recent method which utilizes a model to dynamically optimize the closed-loop process economics in real time.

4. 18. Real-Time Optimization of Cone Crushers

   Författare :Erik Hulthén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process optimization; crushing; CSS; real-time optimization; eccentric speed; cone crusher;

   Sammanfattning : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crushing plant; cone crusher; real time optimization; rock crusher;

   Sammanfattning : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materials. Cone crusher control systems are widely used for wear compensation and machine protection. These systems ordinarily focus on the crusher and not the crushed products. LÄS MER

7. 20. Fibre-Optic AWG Networks Supporting Real-Time Communication in High-Performance Embedded Systems

   Författare :Kristina Kunert; Magnus Jonsson; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time communication; medium access control MAC protocol; traffic dependency analysis; network architecture; Arrayed Waveguide Grating AWG ; optical communication; real-time analysis; optical network; Computer engineering;

   Sammanfattning : High-performance embedded systems communicating heterogeneous traffic with high bandwidth and strict timing requirements are in need of more efficient communication solutions. This thesis proposes two multi-wavelength passive optical networks able to meet these demands. LÄS MER
