  3. 2. Elevers användande av formativ återkoppling i matematik

    Författare :Jenny Green; Kristina Juter; Anders Jönsson; Torgny Ottosson; Lisa Boistrup Björklund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Students are often not satisfied with the feedback they receive, and do not always use it. Providing feedback on student learning has been shown to have a positive effect on learning, and is a key strategy in formative assessment. LÄS MER

  4. 3. Dynamic single-cell modelling of nutrient signalling in budding yeast

    Författare :Sebastian Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nutrient signalling; single-cell; mixed-effects models; stochastic dynamic models; Bayesian inference;

    Sammanfattning : To survive in environments with constantly changing nutrient levels the bud- ding yeast Saccharomyces cerevisiae has a sophisticated nutrient sensing system. A central component of this system is the SNF1 signalling pathway, which primarily helps yeast adapt to glucose limited conditions. LÄS MER

  5. 4. Specifying Safety-Critical Heterogeneous Systems Using Contracts Theory

    Författare :Jonas Westman; Mattias Nyberg; Mats Heimdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contracts; Heterogeneous Systems; Safety; Architecture; Requirements; Specification; Elements; Compositional; IEC 61508; ISO 26262; Kontrakt; Heterogena System; Säkerhet; Arkitektur; Kravhantering; Specifiering; Element; Kompositionell; IEC 61508; ISO 26262; Machine Design; Maskinkonstruktion;

    Sammanfattning : Requirements engineering (RE) is a well-established practice that is also emphasized in safety standards such as IEC 61508 and ISO 26262. Safety standards advocate a particularly stringent RE where requirements must be structured in an hierarchical manner in accordance with the system architecture; at each level, requirements must be allocated to heterogeneous (SW, HW, mechanical, electrical, etc. LÄS MER

  7. 5. Modeling and Stability Analysis of Rate and Power Control Systems in Wireless Communication Networks

    Författare :Anders Möller; Xiaoming Hu; John Baillieul; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Wireless data traffic in cellular networks is currently undergoing a strong global expansion and the demand for high and reliable data throughput increases. Capacity is, however, a limited resource, and in radio resource management a trade-off has to be made between the congestion level, related to cell coverage and interference levels, and the Quality of Service (QoS) or data rates of the users.
