1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Muhammad Umar Farooq; [2023]
   Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

   Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

3. 2. Sustainable Innovation as the driving force in the formation of corporate image

   Magister-uppsats, Linnéuniversitetet/Institutionen för management (MAN)

   Författare :Umar Javed; Muhammad Imran Shahid; [2022]
   Nyckelord :Sustainable Innovation and Corporate image;

   Sammanfattning : The purpose of this research is to discover and examine the impact of sustainable innovation on corporate image. This paper aims to check the influence of eco-friendly innovations on the reputation of the business and then how consumers perceive and think about the business and to discover the level of this influence on small and large businesses in Pakistan we collected data from 65 employees of diverse organization through a survey questionnaire, and the results are obtained through different tests performed on SPSS.

4. 3. Monitoring Network Congestion in Wi-Fi, based on QoE in HTTP Video Steaming Services

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

   Författare :Muhammad Umar Nasir; [2016]
   Nyckelord :QoE; Video Streaming; QoE-QoS Relationship; Packet Loss Pattern; RTT; Active Measurements; TWAMP; Machine Learning Approach.; Technology and Engineering;

   Sammanfattning : Improvements in Internet technology, development of multimedia applications, protocols and improvement in user devices have led to the popularity of multimedia applications, among which video streaming applications are most popular. Streaming video services are sensitive to network conditions, thus making Quality of Experience (QoE) of end users sensitive to network conditions. LÄS MER

5. 4. Practical Aspects of Reduced Complexity LDPC Decoding using Forced Convergence

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

   Författare :Muhammad Umar Farooq; Maria Garcia Garcia; [2016]
   Nyckelord :LDPC; Forced Convergence; Decoding; OFDM; IEEE802.11; Technology and Engineering;

   Sammanfattning : This thesis is an extension to the previous work done at Department of EIT in investigating the complexity reduction of LDPC decoding using the stochastic approximation method to improve the energy efficiency of energy-limited applica- tions, such as in mobile phones. The research carried out in this thesis investigates the complexity and conver- gence results of adaptive performance control algorithm (PCAA) that changes the forced convergence threshold in OMS LDPC FC decoding algorithm.
