Due to increasing oil demand and serious global warming, a green power generation system is urgently requested in transportation. Electric/hybrid vehicles (EV/HEV) have been considered as a potential solution with great promise in achieving high energy/power efficiency and a low environmental impact. The important electric and electronic equipment in EV/HEV are the battery, inverter and motor. How

We discuss some results in coding and decoding for multiple-access channels. A new approach to choosing codes and users' energies for that channel is described. For the case when a bit error probability and a decoding complexity are fixed we construct a region of achievable code rates.

Since the Internet is developing rapidly in size and in complexity as well, it is very hard to adjust quality of service (QoS) parameters. In order to guarantee service quality, efficient resource reservation is needed. The allocation of resources requires a dynamic reconfiguration mechanism that configures a switch, taking into account the incoming traffic fluctuations. This paper presents a new

This publication is designed to provide accurate and authoritative information in regard to the statics in structural engineering. "STATICS FOR CIVIL ENGINEERS" is made up of 7 chapters, concentrating on the main and most important fields of the subject matter covered and presenting a wide variety of examples and exercises. Some related parts with less necessity for the students or experts of stru

The aim of the thesis is to study the change in the Scanian rural society and landscape during the time of the radical enclosure reform "Enskifte" (Sw.) in the early 19th century and the decades therafter up until c 1850. Seven parishes on the southern plain of the province of Scania are studied in more detail, while the province itself is the study area in two of the nine chapters. The theoretica

In the inversion in R 2 of the exponential Radon transform, a scalar function f is found from its integrals, with exponential weight functions, over lines. In this paper we demonstrate how to define two different kinds of exponential Radon transforms for vector fields in R 2 in a natural way. It is shown that having data from these exponential vectorial Radon transforms it is possible to reconstru

Att referera är ett hantverk som kräver reflektion. Hur undviker jag plagiat? Vilka uttalande och outtalade funktioner har referenserna i en text? Hur värderas olika källor? Boken behandlar dessa frågor och hur litteaturhänvisningar fungerar som verktyg när man skriver, samt hur man skriver formellt korrekta referenser. Boken ger en detaljerad genomgång av det sätt att referera som kallas APA-syst

This paper describes the work with F0 and segment duration when developing a prototype system for analysis of speaker age using data-driven formant synthesis. The system was developed to extract 23 parameters from the test words—spoken by four differently aged female speakers of the same dialect and family — and to generate synthetic copies. Audio-visual feedback enabled the user to compare the na

Andelen av de polisanmälda hatbrotten med antiromska motiv som personuppklarats var 2 procent år 2012 och 3 procent år 2013. Denna rapport syftar till en analys över faktorer som ligger bakom att antiziganistiska hatbrott inte uppklaras i högre utsträckning än vad som sker utan istället i stor omfattning läggs ned. Studien ska mot denna bakgrund också ge förslag på åtgärder hur tillgången till rät

Sweden has experienced an increase in the number of individuals on long-term sick leave between 1997 and 2004. This occured along side changes in the social insurance system and led to an increase in the number of individuals permanently excluded from working life. Rehabilitation and activation measures which should have helped people back to work have instead increased the length of sick leave as

Colour is disregarded in the analysis of the grammar of a building façade. Contemporary architecture, as well as traditional historical architecture, is built on a relation between colours. Colour schemes of vernacular architecture is a part of the local regional heritage.A re-established exterior colour scheme in rural areas would strengthen the local identity. In Sweden the dominating part of ve
