Governance patterns and performance of regional strategies in peri-urban areas : comparative analysis of seven cases in Europe and Chine
- 2011
-
Reports (other academic/artistic)abstract
- This report examines how different regional and local governance patterns and specific spatial planning strategies impact on peri-urban land use in Rural Urban regions. It draws from seven regional case studies, presenting a diverse mix of strategies ranging from protecting biodiversity and agricultural land, creating recreation and tourism opportunities to reducing pressure from building and infrastructure development. To study the means of influence or power an analytical framework of ‘policy arrangement’ was employed (Tatenhove et al, 2000): specifying rules of the game, resources, coalitions and discourses. Both government and nongovernment actors such as environmental groups or developers can form coalitions, adopt rules, employ resources and develop discourses to influence policies and developments in urban regions. The analytical and assessment frameworks defined by regional researchers and practitioners helped to organize the case study data and to evaluate both processes and outcomes of governance in peri-urban areas. The outcomes are represented in a summarized way for each strategy and region.The report provides examples of unsustainable developments in peri-urban regions and how certain strategies helped to counteract these, and emphasizes the importance of recognizing peri-urban areas as a policy field in its own right.A sustainable spread of land use over the Rural Urban region requires regional authorities whose jurisdiction covers the Rural Urban region and who have the appropriate mix of policy means of influence and relative power over lower level authorities. Under the current predominant discourse of ‘sustainable’ development largely being equal to economic development, the outcome of sustainability concerns depends on urban areas taking financial responsibility for the inclusion of common good interests such as ecosystem services, cultural heritage and social and environmental justice into the periurban areas. Recommendations for policy makers at different levels conclude the report.

The impact of object size and precision demands on fatigue during computer mouse use
- 2011

In: Advances in Physiotherapy. - : Informa UK Limited. - 1403-8196 .- 1651-1948. ; 13:3, s. 118-127

Journal article (peer-reviewed)abstract
- Prolonged computer use, especially if fatigue ensues, is associated with visual and musculoskeletal symptoms. The aim was to determine the time-course of perceived fatigue in the wrist, forearm, shoulder and eyes during a 60-min mouse task (painting rectangles), and whether object size and/or mouse use demands were of infl uence. Also, we investigated performance (number of rectangles painted), and whether perceived fatigue was paralleled by local muscle fatigue or tissue oxygenation.Ten women performed the task for three conditions (crossover design). At condition 1, rectangles were 45 25 mm, square paint cursor size 1.3 1.3 mm, and mouse – pointer movement ratio 1:26. At condition 2, the same cursor size and mouse – pointer movement ratio was used, but rectangles were smaller. At condition 3, the smaller rectangles were used, but the cursor size was also smaller and mouse – pointer movement ratio was 1:8. The results showed increased self-reported fatigue over time, with the observed increase greater for the eyes, but no change in physiological responses. Condition 2 resulted in higher performance and increased eye fatigue. Perceived fatigue in the muscles or physiological responses did not differ between conditions. In conclusion, computer work tasks imposing high visual and motor demands, and with high performance, seemed to have an infl uence on eye fatigue.

3D head pose estimation using the Kinect
- 2011
-
In: 2011 International Conference on Wireless Communications and Signal Processing (WCSP). - : IEEE Press. ; , s. 1-4
-
Conference paper (peer-reviewed)abstract
- Head pose estimation plays an essential role for bridging the information gap between humans and computers. Conventional head pose estimation methods are mostly done in images captured by cameras. However accurate and robust pose estimation is often problematic. In this paper we present an algorithm for recovering the six degrees of freedom (DOF) of motion of a head from a sequence of range images taken by the Microsoft Kinect for Xbox 360. The proposed algorithm utilizes a least-squares minimization of the difference between the measured rate of change of depth at a point and the rate predicted by the depth rate constraint equation. We segment the human head from its surroundings and background, and then we estimate the head motion. Our system has the capability to recover the six DOF of the head motion of multiple people in one image. The proposed system is evaluated in our lab and presents superior results.

Real 3D interaction behind mobile phones for augmented environments

Conference paper (peer-reviewed)abstract
- Number of mobile devices such as mobile phones or PDAs has been dramatically increased over the recent years. New mobile devices are equipped with integrated cameras and large displays which make the interaction with device easier and more efficient. Although most of the previous works on interaction between humans and mobile devices are based on 2D touch-screen displays, camera-based interaction opens a new way to manipulate in 3D space behind the device in the camera's field of view. This paper suggests the use of particular patterns from local orientation of the image called Rotational Symmetries to detect and localize human gesture. Relative rotation and translation of human gesture between consecutive frames are estimated by means of extracting stable features. Consequently, this information can be used to facilitate the 3D manipulation of virtual objects in various applications in mobile devices.

Smart Baggage in Aviation

Conference paper (peer-reviewed)abstract
- Nowadays, the Internet has dramatically changed the way people take the normal course of actions. By the recent growth of the Internet, connecting different objects to users through mobile phones and computers is no longer a dream. Aviation industry is one of the areas which have a strong potential to benefit from the Internet of Things. Among many problems related to air travel, delayed and lost luggage are the most common and irritating. Therefore, this paper suggests anew baggage control system, where users can simply track their baggage at the airport to avoid losing them. Attaching a particular pattern on the bag, which can be detected and localized from long distance by an ordinary camera, users are able to track their baggage. The proposed system is much cheaper than previous implementations and does not require sophisticated equipment.
