Occupancy models for equal or unequal objects distributed into equal or unequal cells can be represented by random partitions of integers or sets and also by randomly colored and labeled graphs. Applications of occupancy models to statistical disclosure control and to cluster inference in random graphs motivate an interest in entropies of occupancy distributions. We determine and compare entropies
We present the first results from several ongoing studies of the stellara bundances, ages, and chemical trends in the long-lived dwarf stars in the solar neighborhood that belong to the thin and thick galactic disk.We confirm that the trends of α-elements in the thin and thick disk are distinct, and we also find that the thick disk show the typical signature of SN Ia contribution to the chemical e
During the past 10 years, the European Commission has funded numerous dedicated research projects in the field of land degradation and desertification which focussed on data collection in specific field sites, detailed methodological studies, assessment and monitoring experiments, and the development of specific modelling concepts. Although substantial scientific progress has been achieved and som
Avsnitt om snösmältning i tätort, dagvattenledningars funktion vintertid, föroreningar i snö i tätorter, snösmältningens inverkan på reningsverk samt miljösynpunkter på snöhantering.
Young people today are on the move as never ever, both physical, mentally and literally. They reason is the need to gain the knowledge and experience needed to increase their employability. The world is open as ever before and everyone has today the possibilities to learn everything from everywhere at any time.
TiO2(B) crystals were found to be isomorphic with those of its precursor, K2Ti4O9. The former crystals had a large number of facetted voids, 3–30 nm, formed as a result of the removal of potassium and water in preceding hydrolysis and calcination steps, respectively. TiO2(B)-supported vanadium oxide catalysts with loadings in the range 0.25−10 theoretical layers were prepared by impregnation of th
A PID design method is presented. The work done is part of anattempt to find an automatic tuning algorithm for two times two systems inthe process industry. The method tries to minimize the impact of load disturbances. The method was mainly developed because previous designmethods with the same objectives could not handle the processesobtained in decoupled systems.
We investigating the role of anticipation and attention in a dynamic environment in a number of large scale simulations of an agent that tries to negotiate a number of gates that continuously open and close. In particular we have looked at learning mechanisms that can predict the future positions of the gates and control strategies that will allow the agent to pass through the gates unharmed. The
Families of asymptotically regular LDPC block code ensembles can be formed by terminating (J, K)-regular protograph-based LDPC convolutional codes. By varying the termination length, we obtain a large selection of LDPC block code ensembles with varying code rates, minimum distance that grows linearly with block length, and capacity approaching iterative decoding thresholds, despite the fact that t
The development and introduction of heat pumps provides an interesting illustration of policy influence and effectiveness in relation to energy technology innovation. Heat pumps have been supported by several countries since the 1970s as a strategy to improve energy efficiency, support energy security, reduce environmental degradation, and combat climate change. Sweden and Switzerland have been es
Confrontations, break-up, dissociation , the Other – all of these concepts could be seen as troubling, disturbing or problematic, most certainly when the context is music education in a globalised world. In this chapter however, these concepts of instability and insecurity are used to discuss the potential value of tensions and disruption in practising creative music education.
Large anions are attracted to hydrophobic surfaces while smaller, well solvated ions are repelled. Using a combination of explicit solvent and continuum model simulations we show that this leads to significant ion-specific protein-protein interactions due to hydrophobic patches on the protein surfaces. In solutions of NaI and NaCl we calculate the potentials of mean force and find that the resulti
