2. 1. Standardization of Islet Isolation and Transplantation Variables

   Author : Andrew S Friberg; Olle Korsgren; Daniel Brandhorst; Paul R. V. Johnson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet isolation; standardization; enzyme; gradient separation; digital imaging analysis; DIA; transplantation outcome; islet transplantation; prediction; Medical technology; Medicinsk teknik; Medical Cell Biology; Medicinsk cellbiologi; Computerized Image Processing; Datoriserad bildbehandling;

   Abstract : Currently, the transplantation of islets of Langerhans is a viable means to maintain control of blood sugar levels and reduce the risk of hypoglycemia in defined populations with brittle type I diabetes mellitus or those requiring pancreatectomy. However, the process of islet isolation is highly variable and not all isolations result in islet numbers or quality suitable for transplantation. READ MORE

4. 2. Design and Optimization Considerations of Medium-Frequency Power Transformers in High-Power DC-DC Applications

   Author : Amin Bahmani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocrystalline-Magnetic Core; High-Power Isolated DC-DC Converter; Solid-State Transformers; Leakage Inductance; Isolation Requirements; Medium-Frequency Power Transformer;

   Abstract : Recently, power electronic converters are considered as one of the enabling technologies that can address many technical challenges in future power grids from the generation phase to the transmission and consequently distribution at different voltage levels. In contrast to the medium-power converters (5 to 100 kW) which have beenessentially investigated by the automotive and traction applications, megawatt and medium-voltage range isolated converters with a several kilohertz isolation stage,also called solid-state transformers (SST), are still in an expansive research phase.

5. 3. A Bayesian approach to fault isolation with application to diesel engine diagnosis

   Author : Anna Pernestål; Bo Wahlberg; Stefan Arnborg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian probability; fault diagnosis; fault isolation; Bayesian inference; Automatic control; Reglerteknik;

   Abstract : Users of heavy trucks, as well as legislation, put increasing demands on heavy trucks. The vehicles should be more comfortable, reliable and safe. Furthermore, they should consume less fuel and be more environmentally friendly. For example, this means that faults that cause the emissions to increase must be detected early. READ MORE

6. 4. Satisfying Non-Functional Requirements in Model-Driven Development of Real-Time Embedded Systems

   Author : Mehrdad Saadatmand; Mikael Sjödin; Antonio Cicchetti; Radu Dobrin; Paul Pop; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-functional requirements; model-driven development; real-time; embedded systems; Computer Science; datavetenskap;

   Abstract : Design of real-time embedded systems is a complex and challenging task. Part of this complexity originates from their limited resources which incurs handling a big range of Non-Functional Requirements (NFRs). Therefore, satisfaction of NFRs plays an important role in the correctness of the design of these systems. READ MORE

7. 5. Towards active engine mounting systems for commercial vehicles: modeling and analysis

   Author : Hoda Yarmohamadi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear dynamic stiffness and damping; Actuators; Computational model; Conventional engine mount; Vibration isolation; Adaptronic mounting system; Model errors tolerance; Commercial vehicles;

   Abstract : The vehicle engine mounting system, which consists of several mounts connecting the engine to the vehicle structure, not only supports the weight of the engine but also isolates the noise, vibration and the transmitted forces to the vehicle structure. At present conventional elastomeric mounts are widely used in engine mounting systems for commercial vehicles. READ MORE
