1. Finding the QRS Complex in a Sampled ECG Signal Using AI Methods
Master-uppsats, KTH/FysikSammanfattning : This study aimed to explore the application of artificial intelligence (AI) and machine learning (ML) techniques in implementing a QRS detector forambulatory electrocardiography (ECG) monitoring devices. Three ML models, namely long short-term memory (LSTM), convolutional neural network (CNN), and multilayer perceptron (MLP), were compared and evaluated using the MIT-BIH arrhythmia database (MITDB) and the MIT-BIH noise stress test database (NSTDB).

2. Segelbåtens påverkan på marint liv : - En bullerstudie i skärgårdsmiljö
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Segelbåtsflottan i Stockholms skärgård står varje år för hundratusentals användningsdagar, ofta inomskärs och i grunda vikar. Dessa områden är viktiga levnads- och fortplantningsplatser för många av Östersjöns fiskarter, men det saknas studier om segelbåtarnas påverkan på det marina djurlivet. LÄS MER
3. EEG Signal Analysis in the Frequency Domain : An Examination of Abnormalities During the Gait Cycle
Kandidat-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : Many people experience discomfort during movement when using a knee prosthesis. As a result, a study is being conducted to see if biomedical models can be used to produce an optimal prosthetic socket to reduce discomfort. LÄS MER
4. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. LÄS MER
5. Luftburen ultraljudsprovning och signalanalys
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : Equipment and machinery in industries may produce ultrasound when they are getting into failure conditions, for example, when bearings are worn or deteriorated, pipes have pressure leaks, electrical installations have electrical discharge. This project aims to develop a testbed using the airborne ultrasound testing to inspect and monitor the conditions of ball bearings. LÄS MER
