  1. 1. Operating cycle representations for road vehicles

    Författare :Pär Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

    Sammanfattning : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. LÄS MER

  3. 2. Observations on Operating System Security Vulnerabilities

    Författare :Stefan Lindskog; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer security; operating system; vulnerability; intrusion; experiment; modeling; analysis; Datavetenskap; Computer Science;

    Sammanfattning : This thesis presents research on computer security vulnerabilities in general-purpose operating systems. The objective is to investigate intrusions in such systems in order to find and model the underlying generic weaknesses, i.e., weaknesses that would be applicable to many different systems. LÄS MER

  4. 3. Ventilation Performance in Operating Rooms : A Numerical Assessment

    Författare :Cong Wang; Sture Holmberg; Sasan Sadrizadeh; Anna Bogdan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating room ventilation; bacteria-carrying particles; laminar airflow; mixing ventilation; temperature-controlled airflow; computation fluid dynamics; Lagrangian particle tracking; Civil and Architectural Engineering; Byggvetenskap; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. LÄS MER

  7. 5. A new generation of hospital operating room ventilation

    Författare :Parastoo Sadeghian; Sasan Sadrizadeh; Catherine Noakes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventilation systems; bacteria-carrying particles; airflow behaviour; operating room; computational fluid dynamics; surgical site infection; Ventilationssystem; bakteriebärande partiklar; luftflödesbeteende; operationsrum; numerisk strömningsmekanik; kirurgirelaterad infektion; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Surgical site infection is responsible for 38 percent of reported infections after surgery. This infection increases mortality and treatment costs, and prolongs the hospitalization of patients. LÄS MER
