1. 1. Configuration Design of a High Performance and Responsive Manufacturing System : Modeling and Evaluation

   Författare :Daniel Tesfamariam Semere; Bengt Lindberg; Bolmsjö Gunnar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Configuration; Modeling; Evaluation; Manufacturing engineering; Produktionsteknik;

   Sammanfattning : Configuring and reconfiguring a manufacturing system is presented as an issue with increasing importance due to higher frequency of system configuration or major reconfigurations to accommodate new set of requirements and/or the need to configure the system to make it usable across generations of products or product families. This research has focused in the modeling, evaluation and selection decisions which involves multiple, incommensurate and conflicting objectives. LÄS MER

3. 2. Constitutive models of magneto-sensitive rubber under a continuum mechanics basis and the application in vibration isolation

   Författare :Bochao Wang; Leif Kari; Ines Lopez Arteaga; Vincent Coveney; KTH; []
   Nyckelord :Magneto-sensitive rubber; magnetic dependency; frequency dependency; amplitude dependency; temperature dependency; vibration isolation; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Due to its durability, stretchability, relatively low stiffness and high damping, rubber is widely used in engineering anti-vibration fields. However, a major deficiency is that once installed, the mechanical properties of traditional rubber-based devices are fixed where its adaptability to various loading conditions is poor. LÄS MER

4. 3. Model and Dependency Management in Mechatronic Design

   Författare :Ahsan Qamar; Wikander Jan; Carl During; Kristina Shea; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dependency Modeling; Model-Based Systems Engineering MBSE ; Mechatronic Design; Model Integration; Tool Integration; Common Language; Mechatronic Challenges; Domain Specific Language.;

   Sammanfattning : Managing consistency is a major concern in the design of complex engineering systems. At times, inconsistencies may lead to wrong decisions, resulting in design flaws which can compromise safety and cause failures. One cannot forget the 1999 NASA unmanned MARS Climate Orbiter, which was destroyed due to use of inconsistent units by design teams. LÄS MER

5. 4. Distributed Photovoltaics, Household Electricity Use and Electric Vehicle Charging : Mathematical Modeling and Case Studies

   Författare :Joakim Munkhammar; Joakim Widén; Ewa Wäckelgård; Jesper Rydén; Peter Lund; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Photovoltaics; Household Electricity Use; Electric Vehicle Charging; Markov Chain Modeling; Probability Distribution Modeling; Data Analysis; Self-Consumption; Grid Interaction.; Engineering Science; Teknisk fysik;

   Sammanfattning : Technological improvements along with falling prices on photovoltaic (PV) panels and electric vehicles (EVs) suggest that they might become more common in the future. The introduction of distributed PV power production and EV charging has a considerable impact on the power system, in particular at the end-user in the electricity grid. LÄS MER

7. 5. Modeling prediction and pattern recognition in the early visual and olfactory systems

   Författare :Bernhard Kaplan; Lansner Anders; Fred Hamker; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spiking neural networks; pattern recognition; self-organization; prediction; anticipation; visual system; olfactory system; modeling; Computer Science; Datalogi;

   Sammanfattning : Our senses are our mind's window to the outside world and determine how we perceive our environment.Sensory systems are complex multi-level systems that have to solve a multitude of tasks that allow us to understand our surroundings. LÄS MER
