Analytical Calculation of the Ra Surface Roughness during Turning

In this article an analytical equation for calculating the theoretical arithmetic mean surface roughness, Ra, in the case of turning using a tool with a circular nose radius is presented. The calculated Ra-values are verified by experimental results obtained from machining of 7 different workpiece materials. For all measuring series results were obtained that were either better or worse than the t

Performance and implementation of routing and wireless transport layer connections in micro mobility Ad hoc networks

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

Health policy processes in Asian transitional economies

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

Interaktion i forskningspraktiken : vårdvetenskapliga forskares sociala nätverk

This licentiate thesis builds on an interest in scholarly communication and social networks within in library and information science, in particular in the area of information seeking and use. The specific purpose is to create a scientifically founded understanding of how the interaction of caring scientists in social networks contributes to the scientists sense-making in their research practice.

Helsingborgstraktens förhistoria

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

Combined Test Data Selection and Scheduling for Test Quality Optimization under ATE Memory Depth Constraint

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

Strontium Titanate-based Anodes for Solid Oxide Fuel Cells

Popular Abstract in Swedish Syftet med detta arbete har varit att utveckla nya, stabila bränsleelektroder till bränsleceller baserade på fasta oxider, SOFC (solid oxide fuel cells). Vi har undersökt olika keramiska material eller kompositer med lovande egenskaper för att användas på anodsidan av bränslecellerna. För att förbättra redox-stabiliteten så ska bränsleelektroden företrädesvis inte innehThe purpose for this work has been to develop new robust fuel electrodes for solid oxide fuel cells (SOFC). The aim was to find suitable ceramic materials or composites with promising properties for the use as SOFC anodes. Preferably, the electrode should not contain any metal (or at least a metal should not be a major component) in order to improve the redox properties. The present work focuses o
