  1. 1. Ultrasonic measurement principles : modeling, identification, and parameter estimation

    Författare :Jesper Martinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis presents contributions within the fields of ultrasonic modeling and measurement technology, with focus on solutions to difficult modeling and measurement problems. The work is divided into two categories: 1) processing of measurements obtained under non-ideal conditions, such as unsynchronized, distorted, and superimposed signals; 2) estimating acoustic models and parameters from materials, fluids, fluid mixtures, and thin-layered structures.

  4. 3. Manufacturing Decisions and A Multi-Tier Supply Location Decision-Support Model for Enhancing Sustainability in Textile and Clothing Supply Chains

    Författare :Petchprakai Sirilertsuwan; Lantz Björn; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; carbon emissions; global supply chain network design; location decisions; manufacturing decisions; supplier selection; supply chain performance measurement; sustainable supply chain management; total cost calculation; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : A recent trend towards sustainability has led to increases in various sustainable practices, but sustainability has still not been fully implemented into manufacturing and supply location decisions. A fragmented product supply chain, which has various locations and multi-tier suppliers, leads to difficulties in traceability to ensure the supply chain has business, environmental, and social/socio-economic sustainability, known as the triple bottom line (TBL).

  7. 5. Improving accuracy of in situ gamma-ray spectrometry

    Författare :Jonas Boson; Christer Samuelsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gamma-ray spectrometry; in situ measurement; HPGe detector; 137Cs; Monte Carlo; efficiency calibration; measurement uncertainty; Radiological physics; Radiofysik;

    Sammanfattning : Gamma-ray spectrometry measurements performed on site, or “in situ”, is a widely used and powerful method that can be employed both to identify and quantify ground deposited radionuclides. The purpose of this thesis is to improve the calibration of high purity germanium (HPGe) detectors for in situ measurements, and calculate the combined uncertainty and potential systematic effects.
