Infrared spectroscopy techniques have long been utilized in identifying and quantifying species of interest to us. Many of the elementary molecules in the atmosphere interact with infrared radiation through their ability to absorb and emit energy in vibrational and rotational transitions. A large variety of methods for monitoring of molecules and aerosol particles by collecting samples or by using

The study deals with R&D, international spillovers and productivity growth. More specifically the first issue we look at is whether R&D spillovers are transferred across different industries and countries. The effect of R&D conducted within the industry, as will as in other industries and countries, on productivity growth are examined. The second issue concerns what channels and factor

A novel model of role of conditioning in attention is presented and evaluated on a Nao humanoid robot. The model implements conditioning and habituation in interaction with a dynamic neural field where different stimuli compete for activation. The model can be seen as a demonstration of how stimulus-selection and action-selection can be combined and illustrates how positive or negative reinforceme

In agriculture, as in industry, have many physically demanding jobs disappeared and the physical stress factors have changed. However, the working days in farms are often long, and it is difficult to hire workers for help as the work conditions are considered to be harsh. The thermal work environment in farms is one of the factors influencing the work conditions. This study aimed to find out the p

This work focuses on the design of SC-LDPC codes for transmission over non-ergodic, block-fading channels. Our main contribution is an algorithm, allowing to start from a (J,K )-regular, uncoupled LDPC ensemble, from which one can recursively build up a protograph-based SC-LDPC ensemble having any target diversity order d. The diversity order is achieved assuming a low-complexity iterative decodin

This thesis concerns involuntary treatment of alcoholism. Clients committed according to the Swedish Act on Care of Addicts in Certain Cases were treated in the same residential treatment setting as voluntarily admitted clients. After informed consent, 104 clients (73 men and 21 women of whom 56 were compulsorily committed and 47 voluntarily admitted) participated in a test-series, including asses

Colorectal cancers are globally ranked as the third most common cancer form in terms of incidence and mortality. Diet has long been considered as one of the main factors affecting population outcome regarding development of cancer in the colon. Numerous epidemiological studies have found links between consumption of dietary fibres and milk and reduced risk of cancers including colon cancer. To be

Light influences man both physiological and experiential and different kinds of light sources may have different impact. In a laboratory study the influence of two kinds of light sources, fluorescent tubes and LED on the experience of the surrounding lighting as well as if there were differences in the biological reactions. 42 healthy subjects took part in the study. Two levels of ambient light we
