    Sammanfattning : In preference-based Evolutionary Multi-objective Optimization (EMO), the decision maker is looking for a diverse, but locally focused non-dominated front in a preferred area of the objective space, as close as possible to the true Pareto-front. Since solutions found outside the area of interest are considered less important or even irrelevant, the optimization can focus its efforts on the preferred area and find the solutions that the decision maker is looking for more quickly, i.

  3. 12. Engineering Software for Resilient Cyber-Physical Systems

    Författare :Ricardo Diniz Caldas; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Designing, implementing, and verifying resilient cyber-physical systems is challenging. Resilience is the ability to provide the required capability when facing adversity. LÄS MER

  4. 13. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Författare :Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. LÄS MER

  5. 14. High Performance Hybrid Memory Systems with 3D-stacked DRAM

    Författare :Evangelos Vasilakis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid memory systems; DRAM caches; Data migration; 3D-stacked DRAM;

    Sammanfattning : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads limiting performance. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. LÄS MER

  7. 15. Aspect-Oriented Business Process Management

    Författare :Amin Jalali; Paul Johannesson; Flávia Maria Santoro; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Separation of concerns has long been considered an effective and efficient strategy to deal with complexity in information systems.One sort of concern, like security and privacy, crosses over other concerns in a system. Such concerns are called cross-cutting concerns. LÄS MER
