2. 1. Total Shoulder Arthroplasty : clinical and radiological studies on the implant positioning and fixation

   Author : Bakir Kadum; Göran Sjödén; Lars Adolfsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total shoulder arthroplasty; reverse shoulder arthroplasty; stemless shoulder arthroplasty; TESS shoulder prosthesis; comprehensive shoulder prosthesis; scapular notching; arm lengthening; Quick DASH; lateral humeral offset; glenohumeral offset; shoulder anatomy; CT shoulder; shoulder anatomy reconstruction.; ortopedi; Orthopaedics;

   Abstract : Shoulder arthroplasty surgery has shown remarkable progress during the last few decades. A number of factors affect postoperative range of motion, pain and prosthetic durability. Among these factors, the length of the lever arm and joint stability is the ones that can be altered by the selected prosthetic component. READ MORE

4. 2. Aerodynamics of vehicle platooning

   Author : Johannes Törnell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; close proximity; drag; platooning; cab over engine; aerodynamics; yaw; wake; side wind; truck; inter-vehicle distance; lateral offset;

   Abstract : Many factors are pushing automotive manufacturers to increase the efficiency of their fleets; some of these are legislative (requiring reduced greenhouse gas emissions) as well as ensuring sufficient range and power consumption in electric vehicles. An important part of improving the energy efficiency of road vehicles is reducing their aerodynamic drag. READ MORE

5. 3. Aerodynamics of two trucks driving in close-proximity

   Author : Johannes Törnell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drag; aerodynamics; cab over engine; inter-vehicle distance; lateral offset; side wind; truck; platooning; yaw; close proximity; wake;

   Abstract : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. READ MORE

6. 4. Aspects on treatment of femoral neck fractures : studies on treatment methods, surgical approach and external validity

   Author : Sebastian Mukka; Arkan Sayed-Noor; Olof Sköldenberg; Lasse Lapidus; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hip fracture; femoral neck fracture; treatment; total hip arthroplasty; hemiarthroplasty; internal fixation; surgical approach; outcome; dislocation; femoral offset; leg length discrepancy; external validity; ortopedi; Orthopaedics;

   Abstract : Femoral neck fracture (FNF) is a great challenge for today´s health care and is associated with high mortality and morbidity in the elderly.  In the short term several studies in the literature have demonstrated improved hip function, quality of life and fewer re-operations in elderly patients treated with total hip arthroplasty (THA) instead of internal fixation (IF).

7. 5. Truck Steering System and Driver Interaction

   Author : Kristoffer K D Tagesson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steering system; active safety; driver behaviour; active steering; torque feedback; heavy trucks;

   Abstract : This thesis presents a compilation of methods to consider when mapping steering functions and results as vehicle dimensions change. It is concluded that some final tuning inevitably will be required as major changes are performed. It is however possible to create qualified starting points using a set of simple rules as presented.
