1. 1. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
   Keywords : Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

   Abstract : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.

3. 2. Method to assess machinability of engineering steels using coated carbide tools

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Petra Hedberg; [2021]
   Keywords : Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

   Abstract : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested. READ MORE

4. 3. Mechanical dry grinding process of saw chain

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Dennis Svensson; Tobias Falk Svärd; [2019]
   Keywords : dry grinding; abrasive; grinding wheel; grinding disc; grinding wheel; friction; energy; work; chainsaw; saw chain; cutting link; cutting edge;

   Abstract : The cutting links on chainsaws needs to be sharpened regularly to retain its sharpness. The most effective way is to use a machine wheel grinder. However, due to high friction there is a high risk of tempering the steel and damaging the sustainability to wear, resulting in a dull cutting edge. READ MORE

5. 4. Autonomous drone control using UWB indoor positioning and communication.

   University essay from

   Author : Andreas Eckerblad; [2019]
   Keywords : Drone; UWB; Positioning;

   Abstract : This thesis aims to develop and test a autonomous drone system with the use of Ultrawideband(UWB)-indoor positioning system and communication. New indoor positioning technologies are the key to autonomous vehicles where existing once such as GPS is not available in the indoor environments. READ MORE

6. 5. Debt Beyond Borders

   University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/LUMID International Master programme in applied International Development and Management

   Author : Natasha Maria Lund Andersen; [2019]
   Keywords : Debt; Loans; Migration; Development; Myanmar; Thailand; Perceptions; Borrowing Behaviour; Social Cognition Theory; Social Cognition Models; Social Sciences;

   Abstract : In a time where concern over migrant indebtedness as a cross-cutting development issue is growing around the world, this paper sets out to explore how migrant workers from Myanmar in Thailand perceive loans and debt, and how these perceptions may link with the migrants’ borrowing behaviour. Despite the prominence of the Myanmar-Thai migration corridor and evidence that indebtedness is common amongst Myanmar migrants, research and reliable data on the topic remain scarce, ultimately constituting a barrier to evidence-based interventions and policy-making.
