  1. 6. Conductive interferences from multiple EC-motor installation : To measure and mitigate harmonics

    University essay from Uppsala universitet/Signaler och system

    Author : Victor Aitman; [2022]
    Keywords : harmonics; interharmonics; harmonic-mitigation; electromagnetic compability; EMC; övertoner; EC-motorer; störningar; övertonsreducering; elektromagnetiskt kompabilitet; EMC;

    Abstract : Products produced by a Swedish company are requested to be investigated regarding their harmonic and inter-harmonic currents injected into the public supply system to comply with the Swedish standard SS-EN IEC 61000-3-2, Electromagnetic compatibility (EMC).    On behalf of Systemair Sweden AB, this bachelor thesis aims firstly to investigate if their product, PAFEC 4225 WH (Air Curtain), complies with standard SS-EN IEC 61000-3-2, and if not, what measures should be taken; and secondly to develop a low-cost instrument for the measurement of harmonics and inter-harmonics according to standard IEC 61000-4-7 related to the requirements on equipment used in standard SS-EN IEC 61000-3-2.

  3. 7. Shadow Maps Techniques Compared : A Performance Comparison Between Shadow Maps and Cascaded Cascaded Shadow Maps

    University essay from Blekinge Tekniska Högskola

    Author : Ghazi Hicheri; [2022]
    Keywords : Shadow Maps; Cascaded Shadow Maps; Performance; Consumption; Algorithm;

    Abstract : Nowadays, 3D rendering has been widely applied in video games. Every year companies strive to come up with new solutions and implementations that potentially will increase the complexity of an algorithm, combined with trying to improve the realism of the graphics. READ MORE

  4. 8. Two New Methods for Real-Time Per-Face Texture Mapping (Ptex)

    University essay from KTH/Datavetenskap

    Author : Hugo Dettner Källander; Julius Häger; [2022]
    Keywords : ;

    Abstract : Ptex (Per-Face Texture Mapping for Production Rendering) is a technology unveiled by Disney in 2008 that automatizes the process of applying textures to 3D models but is rarely used in real-time contexts, where this process is still largely manual and time consuming. This report aims to compare two new real-time methods, Reduced Traverse and Hybrid, to two existing ones, Discard and Traverse, which could give new insight into the feasibility of widespread real-time Ptex and consequent resource savings.

  5. 9. Designing a Physical Unclonable Function for Cryptographic Hardware

    University essay from Linköpings universitet/Institutionen för teknik och naturvetenskap; Linköpings universitet/Tekniska fakulteten

    Author : Ludwig Bergfalck; Johannes Engström; [2021]
    Keywords : Hardware-based keyseed; Tamper protection; Physical Unclonable Function PUF ; Sensing mesh enclosure; Differential capacitance measurements;

    Abstract : Hardware Security Modules (HSMs) are embedded systems that provide a physically secure data storage and handling environment. This master thesis evaluates an HSM method incorporating cryptographic key generation, key management, and tamper protection. READ MORE

  6. 10. Analysing Aliasing in Java Applications

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Björn Berggren; [2020]
    Keywords : ;

    Abstract : Aliasing refers to the possibility of having multiple references to the same memory location and is a cornerstone concept in the imperative programming paradigm. As applications grow large, it is hard for programmers to keep track of all places in the code where they employ aliasing, possibly resulting in hard-to-predict runtime errors. READ MORE
