… as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the …
… and inherent nature of hedge funds. We employ a multiple unconditional linear regression model wherein 23 Swedish hedge funds are regressed on 10 style indices. In addition to the increased interest in hedge funds and their performance drivers, our unique approach with …
Denna uppsats behandlar en algoritm som löser linjära optimeringsproblem. Algoritmen bygger på en liknande idé som simplexalgoritmen men i denna kan startvärdet även vara en punkt inom tillåtet område eller på randen till detta område. Det behöver inte nödvändigtvis vara en …
… conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled …
… of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the …
… and perturbations. The existing metod for controlling the robot is Linear Quadratic Control. To evaluate the SMC-methodology and compare it with the existing solution simulations using SMC and LQ-control are made with uncertainties and modeling imprecision. Our tests show that a …
… routine is based on Green-Ampt, groundwater is modelled assuming a linear reservoir and the flow routing is done with the kinematic wave equation combined with Manning’s equation. The GIS and the hydrologic model are embedded in one another, allowing calculation of each …
… a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods. When nonlinear Simulink-models are simulated, it is often interesting …
… discharge changes among other things. The first model is a mixed integer linear model (MILP) where the power production is expressed in integers and continuous variables. Minimal discharge, prohibited intervals and non decreasing marginal production equivalent are also included …
… to about 3 m3 per day. The gradient in the area is about 0.5 %. The average linear groundwater velocity was computed to about 5 m per year. The transport of the pollutants might be slower due to adsorption and precipitation. Groundwater sampling indicates that the transport to …
… as close as 10-20 cm above the char on the pine trunks. There was a positive linear relation between the height of the lowest surviving lichen and both the height of the surviving needles in the crown and the height of the soot. The lowest surviving needles were always …

… of sketching. One conclusion about the creative process is that it is a non-linear chain of events influenced by factors like method, external impressions and chance. A complete design, "Trasmattan" ("The rag") is presented. It consists of a colourful striped carpet made from …
… when loading a truck and potential costs for drying. This study is based on linear programming where the crops and grain handling systems constitute the activities. Crop rotation effects are also considered in the model. The results show that two handling alternatives emerges as …
… they consumed. By using data from the enterprise information system and simple linear regression a capacity calculation model was developed to calculate the amount of staff needed given a specific production and delivery rate.
Utveckling av ett nytt system, innefattande elektrisk golvlist och uttag, som medger flytt av de traditionellt fasta vägguttagen
… conception development phase and concretisation phase. They were carried out linear up to the conception development phase. Then iteration between the research phase, idea generating phase, conception development phase was repeated until satisfied result was achieved. The result …
