1. 16. Predicting Railway-Induced Ground Vibrations

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Författare :Nils Persson; [2016]
   Nyckelord :ground vibrations; railway; train; wave propagation; vibration measurements; finite element method; dynamics; Technology and Engineering;

   Sammanfattning : Population growth and densification lead to growing urban environments. Unbuilt land within cities can be used to construct residences and other facilities. Population growth can further lead to a greater demand of transportation, which can require expansion of transportation systems such as railways or road traffic. LÄS MER

3. 17. Sustainable Performance Measurements of Logistics in Dispersed Supply Chains

   Master-uppsats, KTH/Industriell Management

   Författare :Pontus Persson Håstlund; Emelie Widenfors; [2015]
   Nyckelord :Sustainable Performance Measurement; Sustainable Performance Measurement Systems; Sustainable Performance Measurement; Sustainable Performance Measurement Systems;

   Sammanfattning : Pressure on companies to show evidence of compliance with sustainable requirements is increasing. Performance measurement systems (PMSs) assist managers in making such choices that optimize sustainability within supply chain operations. LÄS MER

4. 18. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Xi Chen; [2015]
   Nyckelord :V2V; wireless; channel model; multilink; relaying; sum of sinusoids; correlated Gaussian; maximum likelihood estimation; Technology and Engineering;

   Sammanfattning : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). LÄS MER

5. 19. Implementation of a real-time Fast Fourier Transform on a Graphics Processing Unit with data streamed from a high-performance digitizer

   Master-uppsats, Linköpings universitet/Programvara och system; Linköpings universitet/Tekniska högskolan

   Författare :Jonas Henriksson; [2015]
   Nyckelord :FFT; GPU; Digitizer; Real-time;

   Sammanfattning : In this thesis we evaluate the prospects of performing real-time digital signal processing on a graphics processing unit (GPU) when linked together with a high-performance digitizer. A graphics card is acquired and an implementation developed that address issues such as transportation of data and capability of coping with the throughput of the data stream. LÄS MER

7. 20. Analysis of a Flexible Small-Series Flow Line for Prototype Production of Cutting Inserts : A study carried out at Sandvik Coromant in Gimo in order to evaluate how a new flexibleflow line can be planned in order to meet requirements of short lead times andhigh service level

   Master-uppsats, KTH/Industriell produktion

   Författare :Sigurdur Einarsson; [2014]
   Nyckelord :;

   Sammanfattning : In the modern manufacturing industry the need for faster and more robust product development processes is seen as one of the main strategic areas to focus on in order to support sustainable growth and even long term survival of companies due to continuously increasing global competition. For the metal-cutting tool manufacturer Sandvik Coromant product development is seen as a key strategic area and due to that improvements in the overall product development chain are being worked on.
