In Iran, earthquakes cause enormous damage to the people and economy. If there is a proper estimation of human losses in an earthquake disaster, it could be appropriately responded and its impacts and losses will be decreased. Neural networks can be trained to solve problems involving imprecise and highly complex nonlinear data. Based on the different earthquake scenarios and diverse kind of const
OBJECTIVES: Working on large scale construction sites have been shown to have severe health consequences in terms of increased risk of hospitalization and disability retirement compared to construction work in general. The aim of the present study was to investigate whether large scale construction work involving 12-h workdays and extended workweeks leads to insufficient recovery measured as incre
This paper describes the implementation and evaluation of a generic component to extract temporal information from texts in Swedish. It proceeds in two steps. The first step extracts time expressions and events, and generates a feature vector for each element it identifies. Using the vectors, the second step determines the temporal relations, possibly none, between the extracted events and orders
A project focusing on identifying and describing maritime risks is being conducted in the heavily trafficked water area of the Sound, situated in northern Europe between Sweden and Denmark. This paper reports of a test of a first version of a questionnaire constructed for measuring safety culture onboard vessels.48 crew members on a Swedish registered passenger/cargo ship completed and returned th
This paper presents principal design structures for scalable distributed power systems (DPS) focusing on information flow and management enabling "plug and produce" capabilities. The purpose is a general structure that should be appropriate independent of system capacity. The main needs in future market and power system requires a feasible solution that is adequate in scalability and flexibility f
This paper presents in some detail findings and experiences gained from a new course entitled “Innovation Engineering” (IE). This course is offered in the Technology Management Programme (TM) at Lund University, Lund, Sweden. The incentive for developing the new course was the need for a more integrated and practical approach where technical, customer and application problems from reality confront
This paper presents a discrete model of a sensor path planning problem, with a long-term planning horizon. The goal is to minimize the covariance of the reconstructed structures while meeting constraints on the length of the traversed path of the sensor. The sensor is restricted to move on a graph representing a discrete set of configurations, and additional constraints can be incorporated by alte
Earlier research on collaboration shows that cooperation comprises problems and conflicts. The purpose of this study is to describe successful collaboration even if it unfolds during shorter interaction frequencies. In the article, interactive patterns involved in the construction of these phenomena will be analyzed. Forming the empirical basis for this study are 119 field observations of organize
The paper presents sufficient and almost necessary conditions for the presence of periodic solutions for zero dynamics of virtually constrained under-actuated Euler-Lagrange system. This result is further extended to detect periodic solutions for a class of hybrid systems in the plane and analyze their orbital stability and instability. Illustrative examples are given.
Popular Abstract in Swedish Denna avhandling bygger på ett studium av romerska glaskärl funna på icke-romerska/inhemska fyndorter — huvudsakligen tillhörande den romerska järnåldern (0–400 e.Kr.) — bortom Hadrianus mur i norra Britannien. Romerska glaskärl har påträffats på inalles 60 fyndorter, varav en stor del utgörs av bosättningar av skilda slag, och endast en liten del härrör från gravar. SoThis thesis is based on a study of Roman glass vessels found on non-Roman/native sites - chiefly of Roman Iron Age date (AD 0-400) - beyond Hadrian’s Wall in northern Britain. Roman glass vessels have been discovered on 60 sites in total, the majority of which are settlements of various types, and only a minor part are graves. As a consequence of this, the greater part of the material is strongly
