Landsbygdens egnahem : Egnahemsrörelsen, småbruket och landskapet i sydsvenskt perspektiv

The Swedish state-funded "own-home activity" lasted between 1904 and 1948. In this study the main focus is on the background and the early development og this activity on the Swedish countryside, i.e. on the creation of small-holdings. The dissertation gives the social and political background to the movement; shows the spread of state-funded small-holding in the Swedish countyside during the peri

RHEED and RD studies of III-V semiconductors

The published papers and introductory part of this thesis concentrate on the in-situ characterization of (001) surfaces of GaAs, InAs, InP and GaP. The experimental tools used in these studies were a chemical beam epitaxy (CBE) machine equipped with a reflection high energy electron (RHEED) system and a reflectance difference (RD) optical set-up. In some studies also a reflectance difference spect

The changing geography of innovation : Chinese and Indian regions and the global flows of innovation

Despite the recent theoretical and empirical advancements in the geography of innovation literature regarding the role that global sources of knowledge may have for regional growth and development, research in this field remains focused on successful regions and clusters in developed countries. Hitherto there has been limited research on the role of regions located in developing countries and the

Mass Stabilization, Stability and Settlement in Mass Stabilized Peat

Popular Abstract in Swedish De mekaniska egenskaper som torv normalt besitter gör att den lämpar sig dåligt som undergrund för vägkroppar. Det gängse förfaringssättet har därför varit att gräva ur torven och ersätta den med sprängstensmassor. Vid masstabilisering lämnas torven däremot kvar och dess egenskaper förbättras genom inblandning av något kemiskt bindemedel, företrädesvis cement eller olikPeat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. During mass stabilization, the peat is left behind and its geotechnical properties are improved through mixing with a chemical stabilizer, preferably cement or cement in combination with different by-products

A low-power 8-bit folding A/D converter with improved accuracy

In this paper, an accuracy improving method for calibration of mismatch-induced errors in folding A/D converter is presented. With dynamic auto-zero calibration for the folder, the transistor size of folding differential input pairs can be reduced considerably while keeping integral nonlinearity (INL) low. Using this technique, an 8-bit folding A/D converter is designed and simulated in MATLAB. Be
