1. 1. Contributions to Asynchronous Communication Ports for GALS Systems

   Författare :Jonas Carlsson; Juha Plosila; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GALS; Asynchronous; Asynchronous communication ports; Clock gating; Clock domains; Electronics; Elektronik;

   Sammanfattning : Digital systems commonly use a single global clock signal to synchronize the whole system. This is not always possible and it can be more advantageously to divide the system into separate clock domains, where each clock domain can operate with its own clock frequency. LÄS MER

3. 2. Asynchronous First-Order Algorithms for Large-Scale Optimization : Analysis and Implementation

   Författare :Arda Aytekin; Mikael Johansson; Lin Xiao; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex; optimization; asynchronous; algorithms; parallel; distributed; large-scale; big data; software; serverless; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. LÄS MER

4. 3. Asynchronous Algorithms for Large-Scale Optimization : Analysis and Implementation

   Författare :Arda Aytekin; Mikael Johansson; Panagiotis K. Patrinos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; optimization; asynchronous algorithms; algorithms; parallel algorithms; large-scale; big data; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : This thesis proposes and analyzes several first-order methods for convex optimization, designed for parallel implementation in shared and distributed memory architectures. The theoretical focus is on designing algorithms that can run asynchronously, allowing computing nodes to execute their tasks with stale information without jeopardizing convergence to the optimal solution.

5. 4. Dialogues on the Net - Power structures in asynchronous discussions in the context of a web based teacher training course

   Författare :Annette Johnsson; Utbildningsvetenskap; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; minority; cultural background; sex; ethnicity; gender; age; socio-economic; dialogicity; web based; computer based; CMC; net based; asynchronous; CSCL; teacher education; power structures; dialogues; Group work; team work; symbolic capital; group work;

   Sammanfattning : The general aim of this thesis is to investigate the interaction processes that occur in group dialogues when teacher students work in small groups, using net based asynchronous dialogues to solve a problem in the area of environmental sustainability. More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. LÄS MER

7. 5. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays

   Författare :Hamid Reza Feyzmahdavian; Mikael Johansson; Peter Richtarik; KTH; []
   Nyckelord :Optimization; Delay; Positive system; Asynchronous; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER
