  1. 21. Life-Cycle Costing : Applications and Implementations in Bridge Investment and Management

    Author : Mohammed Safi; Raid Karoumi; Håkan Sundquist; Jan-Eric Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Cost; Life Cycle Cost Analysis; Procurement; Investment; Management;

    Abstract : A well-maintained bridge infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements sustainably and cost-effectively is challenging. Bridge investment and management decisions generally involve selection from multiple alternatives. READ MORE

  2. 22. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments

    Author : Amir Malakizadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Usui wear model; Bi-metals; Flank wear; Johnson-Cook; Inverse identification; Metal cutting; Thermal fatigue cracking; Wear modelling; Finite element method; Response surface methodology;

    Abstract : Traditionally, costly experimental procedures have been followed in industry to optimise the machining operations to secure the maximum efficiency in production line, while the functional requirements of the machined surfaces are fulfilled. In recent years, development of robust numerical techniques such as Finite Element Method (FEM) and advances in computing capacity of computers have made it possible to simulate the machining operations under operational conditions.

  3. 23. Monolithic and semi-monolithic translucent zirconium-dioxide restorations : aspects on design, material and strength

    Author : Fahad Bakitian; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Although many clinical reports have shown high rates of clinical success associated with fixed dental restorations made of traditional zirconium-dioxide (zirconia), clinical failure due to improper design aiming to achieve high strength and optimal aesthetics, still occurs. Previous clinical and laboratory studies indicated that veneering porcelain and the connector represent the weak parts of the fully-veneered zirconia restorations where failure may occur. READ MORE

  4. 24. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features

    Author : Dereje Teferi Lemma; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biometrics; eye detection; video synthesis; liveness detection; camera calibration; damascening; Generalized Structure Tensor; symmetry codes;

    Abstract : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.

  5. 25. Towards enhanced sales and operations planning : Using machine learning for decision support in an engineer-to-order context

    Author : Nils-Erik Ohlson; Jenny Bäckstrand; Maria Riveiro; Hafez Shurrab; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineer-to-order; tactical planning; sales and operations planning; machine learning; trust; konstruktion mot order; taktisk planering; sälj- och verksamhetsplanering; maskininlärning; tillit;

    Abstract : All companies deal with tactical planning questions and decisions, for example balance demand and supply, to be able to create an acceptable delivery ability without too much inventory or resources/capacities. For that, some companies use Sales and Operations Planning (S&OP) as their tactical planning process. READ MORE
