  1. 1. Stressing Knowledge : Organisational closed-ness and knowledge acquisition under pressure

    Författare :Mats Koraeus; J.A. Verbeek; Fredrik Bynander; K. Lauche; P. 't Hart; E.K. Stern; M.H. Leyenaar; M.G. Valenta; S.L. Resodihardjo; Charles F. Parker; Försvarshögskolan; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crisis management; knowledge management; organisational learning; organisational behaviour; expertise; advisory; Statsvetenskap med inriktning mot krishantering och internationell samverkan; Statsvetenskap med inriktning mot krishantering och internationell samverkan;

    Sammanfattning : Organisations have been analytically conceptualised as being somewhat analogous to individuals for a long time. They have culture; they can learn; and they can behave in various odd ways. LÄS MER

  3. 2. Análisis dinámico de un eje de ferrocarril con capacidad de cambio de ancho automático

    Författare :Carlos Casanueva; José Germán Giménez; Asier Alonso; Javier Gil Sevillano; Jordi Vinolas; Jesús M. Busturia; Xabier Pérez; Eduardo Gómez; University of Navarra CEIT and Tecnun; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable gauge wheelset; railway dynamics; ; eje de ancho variable; dinámica ferroviaria; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Sammanfattning : El objetivo de la presente tesis es la mejora de los actuales ejes de ancho variable para su circulación por vías de alta velocidad (AV) a velocidades de hasta 300km/h. En la actualidad los vehículos con ejes de ancho variable no sobrepasan los 250km/h de velocidad de servicio en vías de AV, lo que supone un claro desaprovechamiento de recursos y dificultades de gestión del tráfico para el gestor de la infraestructura a causa de las distintas velocidades punta de los diferentes trenes.

  4. 3. FLOW FIELD IN A HIGH HEAD FRANCIS TURBINE DRAFT TUBE DURING TRANSIENT OPERATIONS

    Författare :Rahul Goyal; Michel J. Cervantes; Bhupendra K. Gandhi; Gabriel Ciocan; Lisa Prahl; Ramis Orlu; Gunilla Andree; Andrea Toffolo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Francis turbine; Steady state; Transient; Particle Image Velocimetry; Vortex Rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydroelectricity plays an important role to balance the stability of grid network.  In order to improve the stability of presently high loaded grids, hydropower plants are being operated over a wide range of operations and experiencing frequent start-stop, load rejection, and load acceptance.

  5. 4. Women's Access to Land in Tanzania : The Case of the Makete District

    Författare :Kerbina Moyo; Peter Ekback; Walter de Vries; Jenny Paulsson; E. August Rosnes; Alexandra Weitkamp; Jesper M. Paasch; KTH; []
    Nyckelord :access to land; women; property rights; customary law; customary land tenure; Real Estate and Construction Management; Fastigheter och byggande;

    Sammanfattning : Access to land is crucial for combating discrimination. Women who are denied such access tend to be disadvantaged, a pattern that results in economic powerlessness. Tanzana is among the most undeveloped nations in the world, where gender inequalities with respect to accessing land are central problems. LÄS MER

  7. 5. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    Författare :Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER
