An important traffic engineering problem for OSPF networks is the determination of optimal link weights. Certainly, this depends on the traffic engineering objective. Regardless, often a variety of performance measures may be of interest to a network provider due to their impact on the network. In this paper, we consider different objectives and discuss how they impact the determination of the lin
Background: Relatives of people with a mental illness who live together can experience additional burdens that may require support. A Web-based tool including a psychoeducation module, a diary, and a password-protected forum was developed to support relatives of a person with depression. Objective: The objective of our study was to explore participants' use of the Web-based tool, with focus on the
How can qualitative, ethnographic and emotional aspects from probe users be mapped at the same time as they get something meaningful in return? The emphasis is here on intellectual rewards during probe work rather than future good designs that in a long term perspective can be beneficial for the probe user. This case study has elaborated the traditional use of cultural probes [1] with a selection
A 7th order polyphase G/sub -m/C IF filter with automatic frequency tuning, implemented in a 0.35/spl mu/m CMOS process, is presented. The filter has a center frequency of 3MHz and a passband of 1MHz. The image band rejection is higher than 57dB, the stop band attenuation is at least 40dB. The in-band spurious free dynamic range is around 53dB. On-chip automatic frequency tuning provides more than
This thesis deals with tools for operational improvement of supply chain performance. The work was aimed at providing knowledge for supply chain developers and practitioners, and identifying and developing tools for improved performance in a supply chain. The investigation was part of a project financed by the European Commission called "Industrial Supply Chain Optimizer" (ISCO). The thesis consis

Simultaneous laser-induced fluorescence (LIF) imaging of formaldehyde and a fuel-tracer have been performed in a direct-injection HCCI engine. A mix of N-heptane and iso-octane was used as fuel and Toluene as fluorescent tracer. The experimental setup involves two pulsed Nd:YAG lasers and two ICCD cameras. Frequency-quadrupled laser radiation at 266 nm from one of the Nd:YAG lasers was used for ex
In this paper, we study a flexible routing strategy for demand protection and a corresponding optimization problem for networks that permanently experience fluctuations of the capacity available on their links. This is an important and novel topic as limited link availability is a fundamental feature of wireless networks; yet majority of work in survivable network design is restricted to total fai
The purpose of this paper is to propose a conceptual model for analysis of marine incidents reported to the Swedish Maritime Administration (SMA)/ SOS database. The model is designed based on a systems approach. The model is theoretically and empirically grounded by combining (i) modelling, and accident and risk analysis techniques and theories; (ii) large amounts of empirical data; (iii) and rese
