  1. 1. On Service Optimization in Community Network Micro-Clouds

    Författare :Nuno Apolonia; Leandro Navarro; Sarunas Girdzijauskas; Felix Freitag; Vladimir Vlassov; Dino Lopez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; micro-clouds; Community Networks; cloud services; social networks; overlay networks; distributed systems; Datalogi; Computer Science;

    Sammanfattning : Internet coverage in the world is still weak and local communities are required to come together and build their own network infrastructures. People collaborate for the common goal of accessing the Internet and cloud services by building Community networks (CNs).The use of Internet cloud services has grown over the last decade. LÄS MER

  3. 2. Data and Visual Analytics for Cyber-physical Systems : Current Situation and Strategies for Action

    Författare :Didem Gürdür; Martin Törngren; Jad El-khoury; Helena Holmström Olsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : Today, cyber-physical systems (CPS) exist everywhere in different sizes, with different functionalities and capabilities. CPS often support critical missions that have significant economic and societal importance. LÄS MER

  4. 3. Constraint-Based Register Allocation and Instruction Scheduling

    Författare :Roberto Castañeda Lozano; Christian Schulte; Ingo Sander; Mats Carlsson; Laurent Michel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; constraint programming; combinatorial optimization; register allocation; instruction scheduling; compiler construction; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Register allocation (mapping variables to processor registers or memory) and instruction scheduling (reordering instructions to improve latency or throughput) are central compiler problems. This dissertation proposes a combinatorial optimization approach to these problems that delivers optimal solutions according to a model, captures trade-offs between conflicting decisions, accommodates processor-specific features, and handles different optimization criteria.

  5. 4. Universal Instruction Selection

    Författare :Gabriel Hjort Blindell; Christian Schulte; Peter van Beek; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; instruction selection; code generation; compilers; constraint programming; combinatorial optimization; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In code generation, instruction selection chooses instructions to implement a given program under compilation, global code motion moves computations from one part of the program to another, and block ordering places program blocks in a consecutive sequence. Local instruction selection chooses instructions one program block at a time while global instruction selection does so for the entire function. LÄS MER

  7. 5. Automated radiation therapy treatment planning by increased accuracy of optimization tools

    Författare :Lovisa Engberg; Anders Forsgren; Marina A. Epelman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated radiation therapy; radiation therapy treatment planning; automated radiation therapy treatment planning; interior-point methods; Optimering; intensitetsmodulerad strålbehandling; dosplanering; automatiserad dosplanering; inrepunktsmetoder; Mathematics; Matematik;

    Sammanfattning : Every radiation therapy treatment is preceded by a treatment planning phase. In this phase, a treatment plan that specifies exactly how to irradiate the patient is designed by the treatment planner. LÄS MER
