  2. 1. Speeding up the Atmosphere : Experimental oxidation studies of ambient and laboratory aerosols using a flow reactor

    Author : Erik Ahlberg; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Secondary organic aerosols; oxidation flow reactor; volatile organic compounds; climate;

    Abstract : Apart from gases, the air we breath consist of tiny, so called, aerosol particles. A cubic metre of air in a relatively clean environment can consist of several billion aerosol particles. The impact of these particles on human health and on climate is significant. READ MORE

    Author : Jenny Ahlberg; Anita van Gils; Linnéuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; board of directors; corporate governance; family firms; Business administration; Företagsekonomi;

    Abstract : This dissertation explores and develops our conception of the board in familyfirms. The family firm is a specific type of organization in terms of corporategovernance, since it encompasses both the family and business systems. READ MORE

  5. 3. Patients with head and neck cancer : aspects on treatment, complications and rehabilitation

    Author : Alexander Ahlberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Head and neck cancer is reported to be the fifth most common cancer globally and around 1,200 new patients are diagnosed in Sweden every year. Historically, survival rates have been rather constant but have started to improve over the last few decades as a result of new and more aggressive oncological treatments. READ MORE

  6. 4. Embedded high-resolution stereo-vision of high frame-rate and low latency through FPGA-acceleration

    Author : Carl Ahlberg; Mikael Ekström; Ignacio Bravo Munoz; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer vision; stereo vision; FPGA; embedded systems; Computer Science; datavetenskap;

    Abstract : Autonomous agents rely on information from the surrounding environment to act upon. In the array of sensors available, the image sensor is perhaps the most versatile, allowing for detection of colour, size, shape, and depth. For the latter, in a dynamic environment, assuming no a priori knowledge, stereo vision is a commonly adopted technique. READ MORE

  7. 5. The role of simulation technology for skills acquisition in image guided surgery

    Author : Gunnar Ahlberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Endoscopy; Laparoscopy; Virtual reality; Simulation; Proficiency-based training; Image guided surgery; Surgical education; Objective assessment.;

    Abstract : Technical proficiency is an essential ingredient in surgical competence, which has hitherto been poorly evaluated. The introduction of disruptive technology into the Operating Room (OR) with respect to operative procedures requires an equally disruptive paradigm shift in surgical training that matches the development in OR technology.
