1. 1. Carbon Abundance in the Milky Way Galaxy

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Calum Kvernes Macpherson; [2021]
   Keywords : Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

   Abstract : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. READ MORE

3. 2. Low-Frequency Noise in InGaAs Nanowire MOSFETs

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Christian Mario Möhle; [2017]
   Keywords : Physics and Astronomy;

   Abstract : Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations.

4. 3. Developing of an ultra low noise bolometer biasing circuit

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Jonas Viklund; [2016]
   Keywords : low noise; ultra low noise; bolometer; biasing; thermal; noise; filter; 1 f-noise; sensors; image sensor; DAC;

   Abstract : Noise in electronic circuits can sometimes cause problems. It is especially problematic in for example high sensitive sensors and high end audio and video equipment. In audio and video equipment the noise will make its way into the sound and picture reducing the overall quality. READ MORE

5. 4. Hardware Design of Real-Time Neural Signal Generator

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

   Author : Anil Kumar Metla; [2015]
   Keywords : Neural Simulator; FPGA; Hardware Design; Technology and Engineering;

   Abstract : Brain Machine Interface (BMI) denominates a collection of systems which interface with the Central Nervous System (CNS). Implementation of a BMI involves the detection, extraction, processing, and translation of the signals from the Central Nervous System. A simulator to generate extracellular recordings is proposed by P.T. READ MORE

6. 5. Frequency Noise in Widely Tunable Lasers for Coherent Communication

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Gabriela Cristina Dascalu; [2013]
   Keywords : ;

   Abstract : The objectives of this thesis are to measure the frequency noise of a widely tunable semiconductor laser, determine the main causes for the frequency uctuations and investigate the requirements for laser frequency noise for mQAM modulation formats by means of simulations. The following theoretical aspects are covered: the derivation of the frequency noise spectrum and the detuned loading effect from the rate equations; the shape and the causes of the frequency noise power spectral density; the derivation of the linewidth spectrum from white and 1/f frequency noise; the functionality of the laser and feedback loop used for the measurements.
