  1. 1. Light scattering for analysis of thermal stress induced deformation in thin metal films

    Författare :Carina Kylner; KTH; []
    Nyckelord :thin metal films; aluminum; optical quality; hillock; initial stage; lateral distribution; thermal stress; light scattering; instrument.;

    Sammanfattning : Today, thin film based devices are found in a wide field of applications. The main reasons are that thin film technology enables access to unique physical properties and possibilities to miniaturize devices. Thin film devices are generally described in terms such as electrical, optical and magnetical properties. LÄS MER

  3. 2. Renal cell carcinoma : factors of importance for follow-up and survival

    Författare :Farhood Iranparvar Alamdari; Börje Ljungberg; Torgny Rasmuson; Sven Lundstam; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; renal cell carcinoma; follow-up; VEGFR-1; PS; ESR; stage; prognosis; metastasis; surveillance; TNM classification; adrenalectomy; angiogenesis; VEGF; Urology and andrology; Urologi och andrologi;

    Sammanfattning : Background: Renal cell carcinoma (RCC) is most lethal of the urological cancers, with more than 40% dying of the disease. About 30% of the patients have metastases at initial diagnosis and up to 40% undergoing nephrectomy for localized RCC develop metastasis. LÄS MER

  4. 3. Stage T1 Urinary Bladder Carcinoma : Investigation of A Population-Based Cohort

    Författare :Hans Olsson; Staffan Jahnson; Per Hultman; Peter Söderkvist; Sten Nilsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Approximately 2 300 new cases of urinary bladder carcinoma (UBC) are diagnosed every year in Sweden. This type of cancer is characterized as a long-standing disease with a high risk of recurrence and progression from an indolent to a more aggressive course. LÄS MER

  5. 4. Runge-Kutta Solution of Initial Value Problems: Methods, Algorithms and Implementation

    Författare :Hans Olsson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; stiffness; software; computational process; differential algebraic equations; ordinary differential equations; Runge-Kutta; initial value problems; time-stepping; system; kontroll; numerisk analys; Datalogi; control; numerical analysis; systems;

    Sammanfattning : The last decades have seen a strongly increasing use of computers for modeling larger and more complex systems. This has been made possible by a combination of increasing computer power and easy-to-use graphical modeling environments and libraries of components. LÄS MER

  7. 5. Preliminary Design Investigations for the Selection of Optimum Reaction Degree for 1st Stage of a High Pressure Gas Turbine

    Författare :Hina Noor; Torsten Fransson; Konstantinos G. Kyprianidis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 1D design; aerodynamic design parameters; flow kinematic; thermodynamics; rotor inlet temperature; cooled turbine; reaction degree; flow coefficient; stage loading;

    Sammanfattning : One-dimensional (1D) turbine design calculation phase requires a handful of input data and choice of design parameters to provide the blade flow path geometry along with the flow kinematics and thermodynamics properties at the blade mid-span. The choice of important aerodynamics design parameters namely reaction degree, nozzle guide vane NGV exit flow angle or flow coefficient and stage loading defines the mid-span flow velocity triangles.
