2. 1. Local Polynomial Regression with Application on Lidar Measurements

   Author : Torgny Lindström; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; differential equations; Funktioner; differentialekvationer; variance-function estimation.; spatial dependence; nonparametric; local polynomial regression; local bandwidth selection; lidar; heteroscedasticity; Bivariate estimation; differential absorption; Functions;

   Abstract : This thesis deals with the problem of estimating a function or one of its derivatives from a set of measurements, mainly of a bivariate or spatial nature which is so common in environmental applications. In this work particular attention has been on the lidar (light detection and ranging) application which is a versatile technique for measurement of among other things atmospheric trace gases.

4. 2. Two Aspects of Automating Logics of Action and Change : Regression and Tractability

   Author : Marcus Bjäreland; Linköpings universitet; []
   Keywords : ;

   Abstract : The autonomy of an artificial agent (e.g. a robot) will certainly depend on its ability to perform "intelligent" tasks, such as learning, planning, and reasoning about its own actions and their effects on the enviroment, for example predicting the consequences of its own behaviour.

5. 3. Essays on the Evaluation of Public Policies

   Author : Michihito Ando; Matz Dahlberg; Che-Yuan Liang; David Neumark; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Local income growth; Local employment; Nuclear power facilities; Synthetic control method; Quantitative case study; Regression kink design; Endogenous treatment; Intergovernmental grants; Flypaper effect; Treatment effect heterogeneity; Instrumental variable; Oral health; Dentures; Price elasticity; Regression discontinuity design; Cost sharing; Randomization test; Economics; Nationalekonomi;

   Abstract : This thesis consists of four self-contained papers.Essay 1: This paper uses the synthetic control (SC) method to examine how the establishment of Nuclear Power Facilities (NPFs) in Japan in the 1970s and 1980s has affected local per capita income levels in the municipalities in which they were located (NPF municipalities).

6. 4. On specification and inference in the econometrics of public procurement

   Author : David Sundström; Kurt Brännäs; Sofia Lundberg; Michael Visser; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; auctions; dependent variable transformation model; green public procurement; indirect inference; instrumental variable; latent variable; log-generalized gamma distribution; maximum likelihood; measurement error; non-linear least squares; objective effectiveness; orthogonal polynomial regression; prediction; simulation estimation; structural estimation; nationalekonomi; Economics; Econometrics; ekonometri;

   Abstract : In Paper [I] we use data on Swedish public procurement auctions for internal regularcleaning service contracts to provide novel empirical evidence regarding green publicprocurement (GPP) and its effect on the potential suppliers’ decision to submit a bid andtheir probability of being qualified for supplier selection. We find only a weak effect onsupplier behavior which suggests that GPP does not live up to its political expectations. READ MORE

7. 5. Position Estimation and Tracking in Colloidal Particle Microscopy

   Author : Mats Kvarnström; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; censored regression; colloidal chemistry; depth estimation; diffusion coefficient; nonparametric function estimation; position estimation; rotational symmetry; tracking; template matching; video microscopy; rotational symmetry;

   Abstract : This thesis presents methods for estimating the locations (including depth) of spherical colloidal particles in images recorded in video microscopy. Understanding the behavior of colloidal interactions and diffusion is of crucial importance in a vast number of areas. READ MORE
