1. 1. Machine Learning for Spatial Positioning for XR Environments

   Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Khaled Alraas; [2024]
   Nyckelord :Extended Reality; Machine Learning; Sensor Fusion; Spatial Data Accuracy Virtual Productions; Augmented Reality; Virtual Reality; Real-time Camera Tracking; Location-Based Services; Gaming Platforms; Sensor Integration;

   Sammanfattning : This bachelor's thesis explores the integration of machine learning (ML) with sensor fusion techniques to enhance spatial data accuracy in Extended Reality (XR) environments. With XR's revolutionary impact across various sectors, accurate localization in virtual environments becomes imperative. LÄS MER

3. 2. Value at Risk Estimation using GARCH Family Models: A Comparison of Different Specifications and Distributions.

   Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Författare :Khaled Jrideh; [2023-05-26]
   Nyckelord :;

   Sammanfattning : The objective of this study is to compare the performance of different GARCH models, under various conditional distribution assumptions, to predict one-day-ahead Value-at-Risk (VaR) for three stocks: Swedbank, Handelsbanken, and SEB over the Covid-19 period. The performance is evaluated using Kupiec, Christoffersen tests and the Quadratic Loss. LÄS MER

4. 3. Digital Front End Algorithms for Sub-Band Full Duplex

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

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

5. 4. Optical properties in chalcogenide glasses and their temperaturedependence. : Literary survey and experiments.

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Matilda Karlsson; Saifallah Khaled Ali; Erik Lundqvist; Ask Löthman Ybo; Kalle Sigås; Oscar Törnquist; [2023]
   Nyckelord :Chalcogenide materials; Chalcogenide glass; Optical properties; Temperature dependence;

   Sammanfattning : This study aimed to investigate methods for determining the temperature dependence of the refractive index and absorption of IR-transparent materials through literary studies and experimental tests. Results from the experimental trials were hard to obtain due to the inherent difficulty of measuring optical properties and yielded only temperature trends of transmittance and reflectance. LÄS MER

7. 5. Accounting Policies Setting of Internally Developed Software and its Subsequent - Expenditures in The Traditional Production Organisations

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Alaa Al Mawed; Khaled Mohamed; [2022-06-30]
   Nyckelord :Accounting Policies; Internally Developed Software; Subsequent Expenditures; Maintenance Expenses; IFRS; Agile Method; Waterfall Method; Intangible Assets.;

   Sammanfattning : Background: In recent decades, technologies have overlapped with many traditional products. The competition is no longer limited to the quality of the products but also to the level of technology used in the products. That resulted in traditional production organisations finding their way into the field of software development. LÄS MER
