Design Requirements

Glass facades and enclosures are highly attractive structures with increasing popularity between architects and engineers. These structures show very specific design requirements so as to guarantee an efficient interaction with the other building components. This is especially true in the case of "adaptive" glass systems, with continuously changing configurations according to a given design criteria. The main goal of this explorative study is the design of an adaptive facade module with antagonistic actuation. The geometry of the glazing system is controlled by pairs of superelastic cables actuated against each other in a reversible way.Superelasticity is here exploited so as to improve the structural behavior of the facade system subjected to wind loads. The efficiency of the proposed design concept is demonstrated via Finite-Element numerical analyses and also from test data obtained from an experimental prototype. It is shown that the the proposed control approach can yield substantial structural enhancements and benefits for the adaptive facade module, which are substantiated by important reductions of maximum deformations and stresses in the cladding elements.

The Relationship

Abstract. TV news are essentially cultural phenomena. Previous research suggests that the often-overlooked formal and implicit characteristics of newscasts may be systematically related to culture-specific characteristics. Investigating these characteristics by means of a frame-by-frame content analysis is identified as a particularly promising methodological approach. To examine the relationship between culture and selected formal characteristics of newscasts, we present an explorative study that compares material from the USA, the Arab world, and Germany. Results indicate that there are many significant differences, some of which are in line with expectations derived from cultural specifics. Specifically, we argue that the number of persons presented as well as the context in which they are presented can be interpreted as indicators of Individualism/Collectivism. The conclusions underline the validity of the chosen methodological approach, but also demonstrate the need for more comprehensive and theory-driven category schemes.

Set Up

Regional research ethics committee (REC) members have voiced a need for the linguistic improvement of informed consent documents to ensure duly informed consent and to ease committee deliberation. We have little knowledge of what elements of language use hamper comprehension, or of the extent of medical researchers’ appreciation of this problem and their willingness to accept intervention. This qualitative, explorative study proposes an intervention design and tests its feasibility and acceptability. Semi-structured interviews with potential REC applicants informed a linguistic intervention benchmarked against existing guidelines, mandated locally and nationally, and then evaluated quantitatively in a semi-controlled set-up and qualitatively via questionnaires. Potential applicants professed the psychological acceptability of linguistic intervention. The intervention comprised a downloadable Microsoft Word template outlining information structure, a detailed guideline offering advice for each move and self-selected linguistic screening. It was used by 14 applicants and had a measurable effect on REC deliberation time and approval rates. The intervention instruments overall made it easier for applicants to produce informed consent documents meeting prescribed ethical standards concerning lay-friendliness. In conclusion, it was found that linguistic intervention is relevant, feasible and psychologically acceptable to REC applicants; it aids their text production process and seems to enhance the lay-friendliness of these texts.

Antagonistic Actuation

Abstract In the paper, different approaches for compliance control for human oriented robots are revealed. The approaches based on the non- antagonistic and antagonistic actuation are compared. In addition, an approach is investigated in this work for the compliance and the position control in the joint by means of antagonistic actuation. It is based on the capability of the joint with torsion leaf springs to adjust its stiffness. Models of joint stiffness are presented in this paper with antagonistic and non-antagonistic influence of the spring forces on the joint motion. The stiffness and the position control possibilities are investigated and the opportunity for their decoupling as well. Some results of numerical experiments are presented in the paper too.

Explorative Study

Customers hold the key role in determining the market of any material. The demand and requirements of the customers are taken into account while the manufacturers produce any product. Mobile phones, being an essential element in today’s world, occupy a large market in today’s business world. Customer satisfaction is the prime motive of the manufacturing companies. Based on a survey conducted, we study the current trend of phone purchase in India and thus analyze the customer’s responses towards different brands and their products. The results depict which brands satisfy the customer requirements.
