Although multi-touch applications and user interfaces have become increasingly common in the last few years, there is no agreed-upon multi-touch user interface language yet. In order to gain a deeper understanding of the design of multi-touch user interfaces, this paper presents semiotic analysis of multi-touch applications as an interesting approach to gain deeper understanding of the way users use and understand multi-touch interfaces. In a case study example, user tests of a multi-touch tabletop application platform called MuTable are analysed with the Communicability Evaluation Method to evaluate to what extent users understand the intended messages (e.g., cues about interaction and functionality) the MuTable platform communicates. The semiotic analysis of this case study shows that although multi-touch interfaces can facilitate user exploration, the lack of well-known standards in multi-touch interface design and in the use of gestures makes the user interface difficult to use and interpret. This conclusion points to the importance of the elusive balance between letting users explore multi-touch systems on their own on one hand, and guiding users, explaining how to use and interpret the user interface, on the other. © 2012 Elsevier Ltd.

The scapula functions as a bridge between the shoulder complex and the cervical spine and plays a very important role in providing both mobility and stability of the neck/shoulder region. The association between abnormal scapular positions and motions and glenohumeral joint pathology has been well established in the literature, whereas studies investigating the relationship between neck pain and scapular dysfunction have only recently begun to emerge. Although several authors have emphasised the relevance of restoring normal scapular kinematics through exercise and manual therapy techniques, overall scapular rehabilitation guidelines decent for both patients with shoulder pain as well as patients with neck problems are lacking. The purpose of this paper is to provide a science-based clinical reasoning algorithm with practical guidelines for the rehabilitation of scapular dyskinesis in patients with chronic complaints in the upper quadrant.

This article presents a 'hands-on' method, targeted towards freshmen product development (or industrial design or engineering design), to create basic form alternatives. The hypothesis that the knowledge and the application of a rational form-generation approach improve the ability to create more and more varied designs is verified by means of an experiment. In this experiment, the effectiveness of the initiated method was measured by comparing the results of a first design session (before initiation of the method) with the results of a second design session (after initiation). The outcome shows definite progress in the basic skills to generate form alternatives: after the initiation, subjects generate more proposals with more variation in surface composition. Parameters like the overall amount of design solutions and the evolution in the variation in surface composition were considered. The experiment indicates that the application of a method can enhance a design process and shows that an analytical and rational approach contributes to the basic skills in the study of form. The two-step manipulation method extends the repertory of possible tools and methods that a designer can implement to cope with the problems concerning the creation of form alternatives. © 2011 Taylor & Francis.

The last decades, lowering the ecological impact of buildings is receiving increased attention by researchers, policy-makers and companies. Mostly the focus is on reducing energy consumption and the use of eco-friendly materials, but the concept of life-cycle thinking is growing in importance. This paper tries to give an overview of the current situation of Life cycle assessment (LCA) in the construction industry, both of regulatory developments and academic case studies. After a short history of LCA, the focus is on LCA methodology, new standards and frameworks and an extensive selection of recent case studies. Despite some inherent limitations of LCA as an analytic tool and fundamental differences between the individual cases, still some common trends can be indicated. In standard buildings, the use phase contributes up to 90% of the total environmental burdens, mainly due to heating and/or cooling. Due to regulations, new buildings become more energy efficient, and thereby other phases of the life cycle gain in importance e.g., choice of materials, construction, end-of-life and water use. These research topics deserve more attention, together with economic issues, the improvement of data quality and implementation of probability density distributions. © 2013 Elsevier Ltd. Source

The majority of the European roads are paved with asphalt material. The dismantling and end of life strategies for these pavements are very divergent among the EU member states and the associated countries. In general the share of recycling the reclaimed asphalt in new asphalt courses is rather lower than it could be technically. The Re-road project aims to address these problems with a holistic approach to the technical and environmental aspects of all steps in the recycling procedures of asphalt material. The overall objectives of the project is to o be able to raise the level of re-use of asphalt concrete to 99% with a minimum of downgrading of the material and a minimal introduction of virgin material into the mixes made with reclaimed asphalt.
