In mobile ad hoc networks wireless nodes communicate over multi hop links and are capable of movement. This paper evaluates a solution that provide these networks with Internet Access and the capability to roam between different access points. Design and implemenation consideration are discussed that focus on behaviour and criterias for performing handover. Simulation result show that the main fac

This paper draws on studies of current knowledge on health policy processes in Cambodia, China and Lao PDR by a number of researchers in the POVILL Consortium. They are based on reviews of international and national literature and of policy documents, interviews with key informants and preliminary findings of small studies in a selection of rural localities. It explores why policy makers have beco

The article constitutes a landscapearchaeological analysis of the prehistoric time in the Helsingborg area, covering chronologically the Stone Age, the Bronze Age and the Iron Age. A basic approach to interprete the archaeological fragments and their cultural context is that they come from oral cultures. To give an idea of the area's prehistory comparisons with other geographical areas, cultures a

Testing is used to ensure high quality chip production. High test quality implies the application of high quality test data; however, the technology development has lead to a need of an increasing test data volume to ensure high test quality. The problem is that the test data volume has to fit the limited memory of the ATE (Automatic Test Equipment). In this paper, we propose a test data truncatio

Sweden, like most other industrialized countries, has an aging population. This is caused by decreases in fertility as well as increases in life expectancy. Table 6.1 shows the percentage of the population over sixty-five and eighty-years-old.

Under senare år har postmoderna företrädare ifrågasatt liberalismen som politiskt värdesystem. Parallellt med den postmoderna diskussionen har det förts en teoretisk debatt om en annan inflytelserik idétradition med rötter i antiken: den klassiska eller medborgerliga republikanismen.I artikeln argumenteras för att republikanismen främjade ett frihetsbegrepp som omfattade krav på vidgade medborgerl

A method for detection and genotyping of genital Chlamydia trachomatis infections based on omp1 gene amplification and sequencing was developed. DNA was extracted from urogenital or urine samples using a Chelex-based method, and an approximately 1,100-bp-long fragment from the omp1 gene was directly amplified and sequenced. Genotyping was performed by BLAST similarity search, and phylogenetic tree

Popular Abstract in Swedish Doktorsavhandling undersöker hur förutsättningar i hemmet, självreglering, akademisk självbild och målorientering påverkar läsförmåga. Att kunna läsa bra är grundläggande för att kunna fungera väl i det moderna samhället där man måste kunna läsa komplicerade texter. Då larmrapporter, kring hur många ungdomar som slutar skolan utan att kunna läsa och skriva, regelbundet The studies in this doctoral thesis investigated how home literacy, self regulation, academic self-concept, and goal orientation influence reading ability. Study 1 investigated the effect of family-based prerequisites, reading attitude, and self-regulated learning on reading ability. Students (n= 4,018) in the eighth grade answered the IEA reading literacy test and the SRLQ. Structural Equation Mo

Popular Abstract in Swedish Polymerer och tensider är molekyler vi stöter på i vårt vardagliga liv, när vi bär hem våra matvaror i plastkassar, tvättar håret, målar huset eller tar en värktablett. Klassificeringen polymer är väldigt bred och innefattar allt från naturliga polymerer som cellulosa, till syntetiska polymerer som polystyren. Polymerer består av små, repeterande enheter, kallade monomeComplexes formed between oppositely charged polyions and surfactant ions are known to have very rich phase behaviour in bulk solution. The work in this thesis investigates the possibilites of using such complexes as surface coatings. Stoichiometric polyion-surfactant ion complexes “complex salts” (CS) consisting of alkyltrimethylammonium surfactant ions and polyacrylates are typically insoluble i
