  2. 1. A perfect score : Validity arguments for college admission tests

    Author : Per-Erik Lyrén; Christina Stage; Marie Wiberg; Simon Wolming; Stephen G. Sireci; Umeå universitet; []
    Keywords : college admission tests; SweSAT; validity; interpretive arguments; predictive validity; equating; item revisions; subscores;

    Abstract : College admission tests are of great importance for admissions systems in general and for candidates in particular. The SweSAT (Högskoleprovet in Swedish) has been used for college admission in Sweden for more than 30 years, and today it is alongside with the upper-secondary school GPA the most widely used instrument for selection of college applicants.

  4. 2. Analysis of ICP pulsatility and CSF dynamics : the pulsatility curve and effects of postural changes, with implications for idiopathic normal pressure hydrocephalus

    Author : Sara Qvarlander; Anders Eklund; Jan Malm; Richard Birgander; Martin U Schuhmann; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cerebrospinal fluid; CSF dynamics; Intracranial pressure; Pulse pressure; Normal pressure hydrocephalus; Posture; Predictive tests; Mathematical modelling; Magnetic resonance imaging; Infusion tests;

    Abstract : The volume defined by the rigid cranium is shared by the brain, blood and cerebrospinal fluid (CSF). With every heartbeat the arterial blood volume briefly increases and venous blood and CSF are forced out of the cranium, leading to pulsatility in CSF flow and intracranial pressure (ICP). READ MORE

  5. 3. Predictive model of perceived driving stability at high speeds under aerodynamic excitations

    Author : Arun Kumar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver-vehicle interaction; unsteady aerodynamics; Driving simulator; on-road tests; predictive model; vehicle stability; subjective evaluation;

    Abstract : The automotive industry is continuously advancing towards more energy-efficient vehicle designs.  Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when  exposed to external excitations such as unsteady aerodynamic forces created by the flow of air  around them.

  6. 4. Predictability in Equity Markets: Estimation and Inference

    Author : Tamás Kiss; Erik Hjalmarsson; Ádám Faragó; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-stationary regressor; Persistence Adjustment; Predictive Regressions; Predictive System; Present-value relationship; Return Predictability; Stock-return Predictability; Non-stationary regressor Persistence Adjustment Predictive Regressions Predictive System Present-value relationship Return Predictability Stock-return Predictability;

    Abstract : The thesis consists of three chapters dealing with predictability in equity markets. The first chapter analyses predictive regressions in a predictive system framework, where the predictor is an imperfect proxy for the expected returns. READ MORE

  7. 5. Toward Predictive Maintenance in a Cloud Manufacturing Environment : A population-wide approach

    Author : Bernard Schmidt; Lihui Wang; Amos H. C. Ng; Fuqing Yuan; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; predictive maintenance; condition monitoring; population-wide approach; machine learning; double ball-bar measurement; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : The research presented in this thesis is focused on improving industrial maintenance by using better decision support that is based on a wider range of input information. The core objective is to research how to integrate information from a population of similar monitored objects. READ MORE
