2. 1. Active school transportation : Understanding the parental decision-making process

   Author : Hanna Forsberg; Stina Rutberg; Anna-Karin Lindqvist; Lars Nyberg; Maria Hagströmer; Luleå tekniska universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Active commuting to school; children; health promotion; parents; theory of planned behavior; physical activity; social norms; Physiotherapy; Fysioterapi;

   Abstract : Few children and adolescents reach the recommended levels of daily physical activity. This trend is evident in the countries examined in this thesis: Sweden and Spain. READ MORE

4. 2. Health, Risk-Taking Behavior and Sexuality in Swedish Adolescents

   Author : Lars I Holmberg; Claes Sundelin; Lars Jacobsson; Dan Hellberg; Erik Bergström; Uppsala universitet; []
   Keywords : Pediatrics; unplanned pregnacy; abortion; adolescents; young men; individual support; Outpatient Clinic for Adolescents; Sweden; decision making; grounded theory; health behavior; risk behavior; sexual behavior; vocational program; theoretical program; Pediatrik;

   Abstract : The overall aims of this research were to develop methods of identifying adolescents with unhealthy and/or risk-taking behavior with special reference to sexuality, and to evaluate support measures for young people in need of such interventions. A further aim was to assess strategies for preventing unhealthy and/or risk-taking behavior. READ MORE

5. 3. Driver behavior models for evaluating automotive active safety: From neural dynamics to vehicle dynamics

   Author : Gustav M Markkula; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; active safety; control behavior; system evaluation; Driver models;

   Abstract : The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. READ MORE

6. 4. Analyzing real-world data to promote development of active safety systems that reduce car-to-vulnerable road user accidents

   Author : Azra Habibovic; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident prevention; Naturalistic observation; Causation analysis; Active safety system; Vulnerable road user VRU ; Driver behavior; Functional requirements; Statistical analysis; VRU behavior;

   Abstract : The overall objective of the thesis is to explore various types of real-world road traffic data and to assess the extent to which they can inform the design of active safety systems that aim to prevent car-to-vulnerable road user (VRU) accidents. A combined analysis of in-depth and police reported accident data provided information on driver behavior and contextual variables, which is valuable for the development of active safety systems.

7. 5. Modeling Approaches for Active Antenna Transmitters

   Author : Parastoo Taghikhani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal model.; MIMO; power amplifier; Active antenna transmitter; hybrid beamforming; electrothermal; active subarray antenna; nonlinear distortion;

   Abstract : The rapid growth of data traffic in mobile communications has attracted interest to Multiple-Input-Multiple-Output (MIMO) communication systems at millimeter-wave (mmWave) frequencies. MIMO systems exploit active antenna arrays transmitter configurations to obtain higher energy efficiency and beamforming flexibility. READ MORE
