1. 1. Linear and Non-Linear Analysis of Plates and Shells by Use of Morley Finite Elements

   Författare :Ulrika Wendt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; explicit dynamic formulation; adaptive methods; Shells Morley element; plates; Germain-Kirchhoff plate theory; finite element method; mixed plate formulation;

   Sammanfattning : The thesis deals with plate bending analysis and shell analysis in static linear and dynamic non-linear situations. The thesis contains two parts. In common for them is the use of the Germain-Kirchhoff plate theory, constant strain, constant curvature triangular plate elements and adaptive improvement of original solution. LÄS MER

3. 2. Mathematical Optimization in Flexible Job Shop Scheduling: Modelling, Analysis, and Case Studies

   Författare :Karin Thörnblad; Göteborgs universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Flexible job shop scheduling; Mixed integer linear programming MILP ; Time-indexed formulation; Makespan; Tardiness; Fixture availability; Preventive maintenance; Night shift; Unmanned time window; Dynamic scheduling; Priority rules; Dispatching rules; Critical ratio; Night shift;

   Sammanfattning : The major theme of this thesis is the mathematical optimization modelling of the flexible job shop scheduling problem. This problem is present in the so-called multitask cell—a production cell at GKN Aerospace's facility located in Trollhättan, Sweden—which has served as a case study during the work with this thesis.

4. 3. Mechanics of paper webs in printing press applications

   Författare :Artem Kulachenko; Sören Östlund; Thomas Abrahamsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; Other engineering mechanics; Övrig teknisk mekanik;

   Sammanfattning : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. LÄS MER

5. 4. Look-ahead Control of Heavy Vehicles

   Författare :Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

   Sammanfattning : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. LÄS MER

7. 5. On Adjacent Channel Interference-Aware Radio Resource Management for Vehicle-to-Vehicle Communication

   Författare :Anver Hisham Unnichiriyath Siddique; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; adjacent channel interference ACI ; vehicle-to- vehicle V2V ; channel state information CSI ; convex optimization; LTE; vehicle-to-everything V2X ; combinatorial optimization; traffic efficiency; 3GPP; medium access control MAC ; power control; radio resource management RRM ;

   Sammanfattning : Safety applications play an essential role in supporting traffic safety and efficiency in next generation vehicular networks. Typical safety applications require vehicle-to-vehicle (V2V) communication with high reliability and low latency. LÄS MER
