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

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

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

    Sammanfattning : 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. LÄS MER

  2. 2. APPLYING UAVS TO SUPPORT THE SAFETY IN AUTONOMOUS OPERATED OPEN SURFACE MINES

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Rasmus Hamren; [2021]
    Nyckelord :Object Detection; You only look once YOLO ; Unmanned aerial vehicle UAV ; Situational Awareness; Critical situations; Autonomous vehicle; Critical Global Positioning System GPS mapping;

    Sammanfattning : Unmanned aerial vehicle (UAV) is an expanding interest in numerous industries for various applications. Increasing development of UAVs is happening worldwide, where various sensor attachments and functions are being added. The multi-function UAV can be used within areas where they have not been managed before. LÄS MER

  3. 3. Homeless women´s emergency housing situation in the city of Gothenburg

    Kandidat-uppsats, Göteborgs universitet / / Institutionen för sociologi och arbetsvetenskap

    Författare :Emelie Ekbrand; [2020-08-18]
    Nyckelord :Women; Homeless; Vulnerability; Emergency Accommodation;

    Sammanfattning : The aim with this study is to gain an insight into how homeless women, who already are avulnerable group in the society, experience an even more vulnerable environment when anemergency accommodation only for women relocated and became part of an emergencyaccommodation where both men and women live. In order to fulfil the purpose two questionswere the core of my material: How do the women get affected in a practical sense, whenmoved from a separate women’s emergency accommodation and become part of anemergency accommodation where both men and women live?; What are these women’sfeelings and perceptions of living close to a gender mixed accommodation?This essay consists of interviews with five women who lives in an emergency accommodationin Gothenburg county.

  4. 4. Nätverksbaserade övervakningskameror i hemmet : Hur påverkar kamerorna den upplevda integriteten?

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Hedda Lundmark; [2020]
    Nyckelord :Home; Smart home; Network-based surveillance cameras; Integrity; Privacy; User experience UX ; Hem; Smarta hem; Nätverksbaserade övervakningskameror; Integritet; Privatliv; Användarupplevelse UX ;

    Sammanfattning : Det har kommit att bli allt vanligare att installera nätverksbaserade övervakningskameror i hemmet som en säkerhetsåtgärd. Tidigare studier som undersöker nätverksbaserade övervakningskameror visar att dessa kameror utgör en möjlig säkerhetsrisk för de boende då det teoretiskt sätt är möjligt för personer som har kunskaper i att bryta sig in i datorsystem att spionera på de boende i hemmet genom övervakningskamerorna.

  5. 5. Deep Learning for Point Detection in Images

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Björn Runow; [2020]
    Nyckelord :Deep learning; Point detection; U-Net; UNet ; HRNet; FCN; Weighted Hausdorff distance; EU-pallet; Computer vision;

    Sammanfattning : The main result of this thesis is a deep learning model named BearNet, which can be trained to detect an arbitrary amount of objects as a set of points. The model is trained using the Weighted Hausdorff distance as loss function. BearNet has been applied and tested on two problems from the industry. LÄS MER
