1. 11. Efficient and Flexible Embedded Systems and Datapath Components

   Författare :Magnus Själander; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flexible; Twin-Precision; Scheduling; Embedded; Multiplier; Multi-Core;

   Sammanfattning : The comfort of our daily lives has come to rely on a vast number of embedded systems, such as mobile phones, anti-spin systems for cars, and high-definition video. To improve the end-user experience at often stringent require-ments, in terms of high performance, low power dissipation, and low cost, makes these systems complex and nontrivial to design. LÄS MER

3. 12. Efficient Backhauling in Cooperative MultiPoint Cellular Networks

   Författare :Tilak Rajesh Lakshmana; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated multipoint; scheduling; quantization errors; precoding; particle swarm optimization; stochastic optimization; decentralized architecture; prediction errors;

   Sammanfattning : The efficient use of the spectrum in cellular systems has given rise to cell-edge user equipments (UEs) being prone to intercell interference. In this regard, coordinated multipoint (CoMP) transmission is a promising technique that aims to improve the UE data rates. LÄS MER

4. 13. Convergence Analysis and Design of Multiple Concatenated Codes

   Författare :Fredrik Brännström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extrinsic information transfer EXIT function; convergence analysis; Multiple concatenated codes; code search; scheduling; parameter estimation; iterative decoding; EXIT chart; puncturing;

   Sammanfattning : The objective of this thesis is to develop a methodology for designing efficient multiple concatenated coding schemes, consisting of two or more constituent codes, concatenated in serial or in parallel. Extrinsic information transfer (EXIT) analysis is found to be a suitable and versatile analysis tool for such codes and thus, the design methodology is based almost entirely on this technique.

5. 14. Assessment of rock mass quality and its effects on charge ability using drill monitoring technique

   Författare :Rajib Ghosh; Håkan Schunnesson; Nuray Demirel; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underground mining; Sublevel caving; Rock mass quality; Borehole filming; Borehole quality; Borehole stability; Borehole instability; Drill monitoring technique; Measurement While Drilling MWD ; Hydraulic in-the-hole ITH drilling; Drill system behaviour; Principal Component Analysis PCA ; Geo-mechanical model; Chargeability; Fracture zone; Shear zone; Cave-in; Cavity; Rock blasting; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. LÄS MER

7. 15. An Optimization Framework for Scheduling of Embedded Real-Time Systems

   Författare :Cecilia Ekelin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Embedded real-time systems - appearing in products such as cars and mobile phones - are nowadays common in our everyday lives. Despite this fact, the design process of such systems is still cumbersome due to the large variety of design constraints that must be considered to ensure a safe operation of the system. LÄS MER
