1. 1. Approach for frequency response-calibration for microphone arrays

   University essay from KTH/Hälsoinformatik och logistik

   Author : Jacob Drotz; [2023]
   Keywords : microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

   Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

3. 2. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Nils Engman; [2023]
   Keywords : Sensors; IoT; Heat Exchangers; Technology and Engineering;

   Abstract : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. READ MORE

4. 3. Virtual Sensing for Cluster Vacuum Control

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Carl Egenäs; Axel Sacilotto; [2023]
   Keywords : ;

   Abstract : The purpose of this project was to develop a virtual sensing model in order to estimate the vacuum level in the milking cluster with data collected further along the milk tube. Measuring the cluster vacuum level is desirable for many applications, such as control and monitoring, but due to the cow's tendency to kick, chew and stomp on anything within reach, placing a sensor in or close to the cluster is both difficult and impractical.

5. 4. Measuring Sprint Speed with Ultra-wideband Technology

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

   Author : Johannes Arenander; [2023]
   Keywords : Speed; Sprint; Ranging; Ultra-wideband; Hastighet; Sprint; Distansmätning; Ultrabredband;

   Abstract : Sprinting can be an important ability in sports, and there are many methods for measuring sprint performance. Two common methods are hand-held timing and fully automatic timing systems. However, hand-held timing is inaccurate due to reaction time, and fully automatic timing can be impractical since it involves complex equipment. READ MORE

6. 5. STUDENT-LED STRESS- AND SLEEP-INTERVENTIONS : Longitudinal changes in mental health symptoms for primary care patients

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Johanna Törnström; [2023]
   Keywords : ;

   Abstract : Mental health issues are a growing problem, and vast contributors are stress-related mental health issues and sleep problems. The health care system is struggling to adjust, and to calibrate the right interventions to the right patients at the right time. READ MORE
