Transcript: Partial vs. impartial Trust Personality Competence A need for the question: who performs the practice we want to change? Gender focus in practical initiatives and policy programmes 4 social dimensions When you have received the text messages to change the timing of your electricity consumption, how often have you decided to do the following in order to change the timing of your electricity consumption? Changed the timing of washing (1)  (2)  (3)  (4)  (5)  (6)  Changed the timing of dishwashing (1)  (2)  (3)  (4)  (5)  (6)  Changed the timing of tumble drying (1)  (2)  (3)  (4)  (5)  (6)  Changed the timing of charging of phone, etc (1)  (2)  (3)  (4)  (5)  (6)  "When we bought the house, it had a thatched roof. It was old and needed to be changed. We could easily have chosen another type of roof. It would have been cheaper and cost less in insurance. But, no, it had to be a thatched roof. We wanted to be faithful to the original style of the house, which is why we also kept the old plank flooring". never Background INCAP Social and gendered engagements significantly impact decisions on energy renovations and practices of flexible electricity use. Aim: to investigate the importance of gendered practices for how households react to flexible electricity use. West and Zimmerman This is your area, John Motivation of the private households Focus on collective action Reaching the environmental sceptics More power and security Relying on a few passionate participants Little experience in the area Lise Tjørring, Industrial PhD defense, November 16th 2017 Partners The positioning in the life cycle influenced people's willingness and capacity to energy renovate Targeting women or rethinking the way we develop solutions? Loosening the boundaries of fixed categories? Financial incentives vs. a focus on (gendered) practices Theoretical attention Aim: to investigate the significance of gender in private households for decisions on energy renovations. Those green tiles in the bathroom, they have to go Foucault From homogenous households to engagements between household members, home and energy advisor Conducted by co-author: • Participant observation in a variety of meetings, an energy fair and conferences • Literature study • Semi-structured interviews with project managers, citizens and builders The process of analysis I'm in the bathroom for 5 min Research focus Paper 1 addresses the social engagement between the energy advisor and the family and between the home and the human actors in the context of energy renovation.

However, silica nanotubes proved to be more suitable with large molecules drug. * This nanostructured tubes have been used with anti-cancer Doxorubicin and optimized the geometry for minimum energy using Hyperchem. Resultes were comparable with previously reported data. * Steric effects plays an important role in the loading efficency. Si-Ti-Sv * The efficiency of silica-titania sieves as bioactive materials as well as their potential to be a suitable nano-carrier have been examined by using a new anti-bacterial agent, Izohidrafural * Izohidrafural, the new antibiotic agent exhibited the highest antimicrobial efficiency, superior to the common drug Nitrofurantoin against the majority of E. coli strains, with average MIC of (4.68 µg/mL), followed by silica-titania sieves loaded with Izohidrafural. * The non-loaded silica-titanium sieves exhibited the highest antimicrobial activity against the gram-positive cocci. Nitrofurantoin Preparation technique Sol-Gel Sol-Gel Adjustments: Synergistic effect The synergistic effect might occur due to the fact that the Titanium dioxide, in form of anatase, in Si-Ti-Sv, has photocatalytic properties and thus the ability of creating reactive oxygen species (ROS)...

Transcript: The problem to be addressed is to perform 3D data registration of an object within a scene using a network of cameras and inertial sensors. Top view Motivations 'Height' indicates the error in the height measuring process (input), shown in cm X, Y and Z are the elements of t vector (output), shown in cm Performing 3D data registration and scene reconstruction using a set of planar images is still one of the key challenges of computer vision. Average processing times in ms for different size of inertial planes. Infinite homography is used to construct image plane of virtual camera. Homography is used to project virtual images onto Euclidean planes in the scene. A person within the scene is being observed by three cameras Extrinsic Parameters Among Cameras A network of cameras, whose usage and ubiquitousness have been increasing in the last decade, can provide such planar images from different views of the scene. x and y indicate the errors in image correspondences (input), shown in pixel X, Y and Z are the elements of t vector (output), shown in cm 3D reconstruction is obtained by stacking several inertial planes Architecture Modelization of Uncertainties Recently, IS has been becoming much cheaper and more available so that nowadays most smart-phones are equipped in both IS and camera sensors. 3D earth cardinal orientation (North-East-Down) is one of the outputs of an IS. Keeping the intersection of shadows The yellow parts are implemented on GPU How can we benefit from having a network of IS and camera couples, for the purpose of 3D data registration? Extension to a network IS' noise is assumed by what is provided by the manufacturer X, Y and Z are the elements of t vector, shown in cm Data of 3rd camera-IS couple 2D images Each point on a virtual image plane conveys an uncertainty due to IS noise Each projected point onto an inertial plane in the scene conveys some uncertainties due to IS noise plus translation vector's noise Having a model of such uncertainties is of importance in fusion stage of the points projected from different cameras and moreover for a further application which will use the final registered points We used statistical geometry to modelized Problem Statement Considering each camera as a light projector, there will appear three shadows on inertial plane 3D orientations 3D reconstruction of the person A set of camera-IS couples can be used to cover the scene from different views PDF (Probability Distribution Function) of results (estimated t) Translation recovery Volumetric reconstruction of a scene normally is a heavy process and time consuming We developed a real-time algorithm using CUDA enabled GP-GPU. Data of 1st camera-IS couple Data of 2nd camera-IS couple It provides the cross-section of the inertial plane with the object. Two arbitrary points in the scene are selected. Their height w.r.p. one camera is measured. The translation t is estimated. Among the extrinsic parameters among two cameras, namely rotation R and translation t, the R is already relaxed once we used the concept of virtual cameras. What remains is t, for which an effective method is introduced to recover. t = f(the height of two arbitrary points w.r.t. one camera, image correspondences) Target applications: Surveillance, human behaviour modelling, virtual-reality, smart-room, health-care, games, teleconferencing, human-robot interaction, medical industries, and scene and object understanding. Average processing times in ms for different number of inertial planes. Illustrative example Real-time implementation using GP-GPU Overall view The certainty of the proposed method has been empirically in three different impacts: Noise of IS 3D observation Heights measurement errors Extraction of image correspondences Geometry behind 3D orientation of IS is fused with 2D image to provide an earth-aligned virtual camera. The orientation is used to virtually generate a set of Euclidean planes in the scene. The 3D data registration is obtained by projection of virtual images onto the Euclidean planes.
