1. 16. Spectral density approach for dynamic analysis of high-speed railway bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Alket Ciku; Vlad Gavriliuc; [2022]
   Keywords : ;

   Abstract : The focus of this thesis is to introduce the concept of train signature in the spectraldensity approach used in the dynamic analysis of simply-supported railway bridges.Due to the increased transportation demands, longer trains with higher axles loadsand top speeds are being developed.

3. 17. Localization For AutonomousDriving using Statistical Filtering : A GPS aided navigation approach with EKF and UKF

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Devrat Singh; [2022]
   Keywords : Land Vehicle Localization; Sensor Fusion; GNSS-INS Fusion; UKF; EKF;

   Abstract : A critical requirement for safe autonomous driving is to have an accurate state estimate of thevehicle. One of the most ubiquitous yet reliable ways for this task is through the integrationof the onboard Inertial Navigation System (INS) and the Global Navigation Satellite System(GNSS). READ MORE

4. 18. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

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

   Author : Sofie Johannesson; Sebastian Skog; [2022]
   Keywords : Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

   Abstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

5. 19. An investigation of circumstances surrounding prosthetic users’ fall and fear of falling : A Cross-Sectional Survey

   University essay from Jönköping University/Hälsohögskolan; Jönköping University/HHJ. Ortopedteknisk plattform

   Author : Jens Dyekær Nielsen; Sara Overgaard Dich; [2022]
   Keywords : Fear of falling; prosthetic user; falls; physical and psychological factors; Falls Efficacy Scale-International; ABC; G-SAP; rädsla för att falla; protestanvändare; falla ramla; fysiska och psykologiska faktorer; Falls Efficacy Scale-International; Activities-specific Balance Confidence; ; Gait-Specific Attentional Profile;

   Abstract : SummaryBackground Prosthetic users face significant challenges both physically and psychologically. Falling poses a significant risk for the individual, and a consequence of this is gaining a fear of falling and self-imposed restrictions. These consequences can have a major impact on the individuals’ health and quality of life. READ MORE

6. 20. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Joacim Sundh; [2022]
   Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

   Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE
