  1. 1. Near Field millimeter Wave Antenna Measurements

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

    Author : Bharath Manjunatha; [2023]
    Keywords : Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

    Abstract : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. READ MORE

  3. 2. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  4. 3. 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

  5. 4. Riskfaktorer för anestesirelaterad gastroesofageal reflux, med fokus på brakycefala hundar

    University essay from SLU/Dept. of Clinical Sciences

    Author : Angelica Hedman; Jenny Larsson; [2018]
    Keywords : brakycefal; allmän anestesi; gastroesofageal reflux; regurgitation; hund;

    Abstract : Gastroesofageal reflux (GER) innebär att maginnehåll rör sig passivt från magsäcken och upp i foderstrupen, vilket kan ske i både vaket och sövt tillstånd. En regurgitation är en gastroesofageal reflux som rör sig vidare upp i munhåla och noshåla. READ MORE

  6. 5. Power-Efficient Settling Time Reduction Techniques for a Folded-Cascode Amplifier in 1.8 V, 0.18 um CMOS

    University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

    Author : Jimmy Johansson; [2017]
    Keywords : Folded-Cascode; Settling Time; Settling Time Reduction; Slew Rate; Slew Rate Enhancement; Operational Amplifier; Recycling Folded-Cascode; 180 nm CMOS; Test Buffer; Power-Efficient; Single-Stage Amplifier; Linear Settling Period; Slewing Period;

    Abstract : Testability is crucial in today’s complex industrial system on chips (SoCs), where sensitive on-chip analog voltages need to be measured. In such cases, an operational amplifier (opamp) is required to sufficiently buffer the signals before they can drive the chip pad and probe parasitics. READ MORE
