  1. 1. Avoiding Frequency Cancellation Using Multiple Microphones in a Surveillance Camera

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

    Author : Victoria Ringsmose; [2021]
    Keywords : Audio; analog electronics; acoustics; interferense; cancelled frequencies; surveillance; multiple microphones; frequency analysis; crossover filter; analog filter; Technology and Engineering;

    Abstract : In surveillance it is important that the recordings are accurate and in as high quality as possible. The surveillance surroundings and equipment can alter and change the audio and needs to be compensated for. This master thesis project investigates whether using multiple microphones could improve the audio quality. READ MORE

  2. 2. Development of grout for deep shaft

    University essay from KTH/Byggteknik och design

    Author : Karl Lindberg; Adam von Krusenstierna; [2021]
    Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

    Abstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE

  3. 3. Exploring Change Point Detection in Network Equipment Logs

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Tim Björk; [2021]
    Keywords : Change point detection; log change detection; time series data; signal processing;

    Abstract : Change point detection (CPD) is the method of detecting sudden changes in timeseries, and its importance is great concerning network traffic. With increased knowledge of occurring changes in data logs due to updates in networking equipment,a deeper understanding is allowed for interactions between the updates and theoperational resource usage.

  4. 4. Tests of Series Arcing and Arc Fault Detection Devices in Low Voltage Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ghazal Al Qabbani; [2021]
    Keywords : ;

    Abstract : Unwanted electrical arcs are a concern in fire and electrical equipment safety. Arcs in electrical systems can be categorized into two main groups, traditionally called: Series and parallel arc faults, or more recently called low current and high current arc faults. READ MORE

  5. 5. Comparing Analog and Digital Non-Linear Sonic Signatures : an Investigation on Creative Application and Subjective Perception using the Universal Audio 1176 FET Compressor

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Behzad Mehrnoosh; [2021]
    Keywords : compression; compressor; non-linear; distortion; sonic signature; analog; hardware; digital; software; emulation; modeling; 1176;

    Abstract : Historically, compression was primarily used as a preventative measure to reduce the risk of clipping or overloading equipment in the recording signal chain. Research on the topic has revealed that modern production applications more commonly include utilizing compression as a creative effect, to impart distortion, manipulate timbre, and modify transients, rather than to control the dynamic range of audio signals.
