In-plane conductive heat tansfer in solid and porous planar structures
2011
Methods for determining the in-plane thermal diffusivity in a planar sample geometry were developed. These methods were tested and verified by measuring planar metal samples with known thermal properties. The techniques used were based on heating the sample at one edge and recording the evolution of the temperature field in the sample by a thermographic camera. The temperature fields at different times were processed and then fitted by a solution to a heat equation describing the experimental setup, thermal diffusivity as one of the fitting parameters. In the first experimental setup the sample was placed in a weak constant flow of air, and the situation was improved in the second setup by …
Droonijournalismi : kauko-ohjattavien kamerakopterien toimituskäyttö
2016
Camera drones (remotely piloted aircrafts or unmanned aerial vehicles) open up new and exciting possibilities for journalistic newsgathering and video and photo shooting. The current report describes and analyses the results of the research project called “Drone Journalism: UtilizingRemotely Piloted Aircrafts (RPA) in Journalistic Purposes”. The project lasted 12 months (1.4.2015-31.3.2016) and was funded by Helsingin Sanomat Foundation. The project was carried out at the Department of Communication of the University of Jyväskylä. The aim of the project was to clarify the problems and possibilities of utilizing camera drones for journalistic purposes. The project focused on: 1) national and…
CCTVCV: Computer Vision model/dataset supporting CCTV forensics and privacy applications
2022
The increased, widespread, unwarranted, and unaccountable use of Closed-Circuit TeleVision (CCTV) cameras globally has raised concerns about privacy risks for the last several decades. Recent technological advances implemented in CCTV cameras, such as Artificial Intelligence (AI)-based facial recognition and Internet of Things (IoT) connectivity, fuel further concerns among privacy advocates. Machine learning and computer vision automated solutions may prove necessary and efficient to assist CCTV forensics of various types. In this paper, we introduce and release the first and only computer vision models are compatible with Microsoft common object in context (MS COCO) and capable of accurately…
