2. 1. Model Selection and Sparse Modeling

   Author : Yngve Selén; Peter Stoica; Jean-Jacques Fuchs; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model selection; model order selection; model averaging; nested models; sparse models; Bayesian inference; MMSE estimation; MAP estimation; ML estimation; AIC; BIC; GIC; RAKE receivers; pulse compression; radar; linear models; linear regression models; Signal processing; Signalbehandling;

   Abstract : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. READ MORE

   Author : Rainde Naiara Rezende de Jesus; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

5. 3. The Quest for Robust Model Selection Methods in Linear Regression

   Author : Prakash Borpatra Gohain; Magnus Jansson; K.V.S Hari; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model selection; information criterion; linear regression; sparsity; high dimensional; Electrical Engineering; Elektro- och systemteknik; Mathematical Statistics; Matematisk statistik;

   Abstract : A fundamental requirement in data analysis is fitting the data to a model that can be used for the purpose of prediction and knowledge discovery. A typical and favored approach is using a linear model that explains the relationship between the response and the independent variables. READ MORE

6. 4. On implant integration in irradiated bone : clinical and experimental studies

   Author : Jan Nyberg; Börje Svensson; Christer Dahlin; Carina B. Johansson; Bo Sunzel; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implant; osseointegration; radiation therapy; bone remodeling; histomorphometry; hyperbaric oxygen therapy; gene expression and in vivo; Surgery; Kirurgi;

   Abstract : Radiation has an impact on the processes involved in bone- healing, regeneration and remodeling. The mechanisms that cause impaired bone healing of dental implants are not fully understood. Adjunctive treatments to revers radiation effects are limited. READ MORE

7. 5. On enhancement of bone formation using local drug delivery systems

   Author : Ali Alenezi; Ann Wennerberg; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone formation; local drug delivery systems;

   Abstract : Introduction: Despite that many reports have confirmed the long-term clinical success rates associated with implant treatment, implant failure to achieve and maintain osseointegration still occurs in many cases. Local and sustained drug release at the bone-implant interface is one of the strategies that have been suggested to improve the osseointegration. READ MORE
