  1. 11. Aerodynamic Optimization of Low Observable Engine Intake Duct

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Laszlo Vimlati; [2022]
    Keywords : NSGA-II; CFD; Air Intake; S-Duct; Optimization; Pressure Recovery; Distortion.; NSGA-II; CFD; Intagskanal; Optimering; Tryckåtervinst; Flödesdistorsion.;

    Abstract : An aerodynamic shape optimization procedure was performed on a low observable engineintake duct. The intake duct was fixed in its throat and aerodynamic interface plane (AIP)sections, while leaving up to 7 design parameters free to deformation in the centroid curveand mid section profile.

  3. 12. Matched Reassignment of the Ultrasound Data of Breast Lesions

    University essay from Lunds universitet/Matematisk statistik

    Author : Robert Vujasic; [2022]
    Keywords : Mathematics and Statistics;

    Abstract : The goal of this thesis was to, from several randomly selected patients with diagnosed malignant and benign tumors, record optimal lambdas and respective Renyi entropies for each lambda, run a basic statistical analysis of the results and see if there is any significant difference between lambdas/Renyi entropies of malignant and benign lesions.\\ The results showed no significant difference.

  4. 13. Ornamentation in the Digital Age

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Karl Östvall; [2022]
    Keywords : Ornament; Ornamentation; Digital Manufacturing; Digital Design; Complexity; Arts and Architecture;

    Abstract : Decoration has been central to architecture throughout history. Since the beginning of the 20th century, the question of ornament in architecture has been oscillating between the positions of redundant and essential. READ MORE

  5. 14. Ventilation systems in Low Energy Houses: augmentation of mixing in a small-scale water model by generating resonance

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Borja Chocarro de Erauso; [2022]
    Keywords : Stratification; buoyancy frequency; resonance; mixing; passive house; water model;

    Abstract : Some passive houses are provided a warm supply flow inlet coming from a mechanical ventilation system, creating issues of shortcut ventilation as a result of an originated density layer stratification, since the supplied warm air is confined to the ceiling level. In this way, there exist several complaints of thermal discomfort and poor indoor environmental quality in passive houses. READ MORE

  6. 15. Temperature Compensation in CMOS Ring Oscillator

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Xiaohua Wei; Dingyufei Zhang; [2022]
    Keywords : Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

    Abstract : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. READ MORE
