  3. 2. "Det är viktigt att ta med att man är utsatt varenda gång man går in genom dörren"  : En kvalitativ studie om hot och våld bland personal inom tvångsvård

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för socialt arbete (SA)

    Författare :Maryana Stifanos; Linus Hedström; [2023]
    Nyckelord :sis; tvångsvård; hot; våld; behandlingspersonal; totala institutioner; emotionellt arbete; roller; känsloregler; kollegialt stöd; ipad; ytligt agerande; djupagerande;

    Sammanfattning : This paper examines treatment staff’s experience of threats and violence at The Swedish National Board of Institutional Care (SiS homes). The following study is based on eight different qualitative interviews with treatment staff at four different SiS homes around southern Sweden. LÄS MER

  4. 3. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Teodor Renman; Charlie Ringström; [2023]
    Nyckelord :Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Sammanfattning : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. LÄS MER

  5. 4. Forecasting Visitors in Smart Building Environments : Modeling and estimation of the number of guests using SARIMAX

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Nour Alhuda Albashir; Hamoud Danial; [2023]
    Nyckelord :SARIMAX; People Counter; Time Series;

    Sammanfattning : Time series modeling is a commonly used approach in exchange for studying and analyzing the data to support decision-making in companies based on historical data and thereby help them to save costs. This work introduces a forecasting framework that utilizes a seasonal autoregressive integrated moving average with exogenous variables (SARIMAX) model to forecast the number of people expected to enter a building within a short period.

  7. 5. Rendering Photorealistic Images of Sticky Notes in Synthesized Indoor Environments : Creating a synthetic dataset in procedurally genererated environments

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Karl Eknefelt; [2022]
    Nyckelord :Computer vision; Computer graphics; Synthetic; Procedural; Dataset;

    Sammanfattning : This thesis is about creating a synthetic data generation pipeline to replace the manual process of adding bounding box-labeled images of sticky notes to an evaluation dataset of a traditional CV algorithm. With this approach, 462 labeled 12 megapixel-images in 55 different, procedurally varied scenes were generated in 8 hours using a MacBook M1 Max laptop. LÄS MER
