AbstractResearch and development in the last decades have led to a silicon process that has been expected to become inherently undependable in the near future when migrating towards new technologies. The special priority program (SPP) 1500 funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) in 2010–2016 and the Variability Expedition funded by the National Science Foundation (NSF) in 2010–2015 made a joint effort to explore design challenges of Power Consumption, Reliability, Interference, and Manufacturability under such a design requirement.

In combination with the author's experiences in design for integrated unit for natural gas field gathering and transmission, this paper describes conventional practices and technical characteristics of integrated unit in the processes of standardization design and modularization establishment and analyzes the initial application of pneumatic control ball valve, wedge-shaped flowmeter and other new technologies for surface facilities in the gas field. As a result, a new design idea is proposed in this paper, i.e., to improve the integration level of surface facilities, to minimize power consumption and maintenance works and to realize unattended work mode.

The article evaluates science sectors and effectiveness of scientific research in the countries forming the BRICS group, as well as the current state of scientific and technological cooperation among the group members. The science sectors of the countries under consideration differ markedly, while facing similar problems relating to government regulations and external environments. The differences exist in total expenditures on research and development (as a share of GNP), in the scope of governmental funding (large in Russia and India, but small in China), and in the distribution of allocations among various areas and types of R&D activities. China appears to have the most well-adjusted science sector among the BRICS members. It includes not only strong universities but also high-tech companies that invest actively into research and development. The overall impact (inferred from citation indexes) of fundamental and exploratory research performed in BRICS countries remains low. BRICS's scientists prefer to collaborate with their colleagues from the world-leading countries rather than with their fellows from BRICS. Yet, in contrast to the world trend, in all BRICS countries, except Russia, a share of internationally co-authored publications is now decreasing. BRICS members have more similar interests and priorities in technological development, including infrastructural and large technological projects, than in science. Currently, bilateral cooperation in technology prevails, while the projects involving all members of the group still remain at the stage of preliminary evaluation and discussion. Russia cooperates most closely with China and India, including joint projects in such high-priority directions as new materials, photonics, biomedical, space and information technologies. For Russia, cooperation in technological development appears to be of most interest because it can lead not only to introduction of new technologies but also help to create large Russian innovative companies. Development of successful multilateral cooperation in science and technology among the BRICS members is the key for this group, originally formed for geopolitical reasons, to evolve into an effective economic union.

At present, people pay more attention to the energy consumption of building electrical design, the use of energy-saving design can maximize the energy conservation resources, and ultimately increase the pace of social sustainable development. Therefore, the energy-saving designers involved in the need to follow the economic rational, safe and feasible benchmark to select the appropriate energy-saving measures to increase research and development of new technologies, new products and new energy, the concept of sustainable development to be implemented. In view of this, this paper mainly analyzes the energy saving technical measures in the electrical design of thebuilding.

The Relationship

This chapter deals with of recent novels and films that project forward into the near future, suggesting where surveillance might be heading. In Kim Stanley Robinson’s 2312, surveillance is figured into a future world of interplanetary environmentalism, in protecting planets and helping to monitor the ‘rewilding’ of an environmentally devastated Earth. Neill Blomkamp’s film Elysium fashions another Earth under environmental stress, patrolled by stringent surveillance operatives and systems that also screen the put-upon inhabitants from the eponymous eutopian space station literally and metaphorically above them. The film concentrates on the utopian urges of that population in their endeavour to overcome oppressive monitoring and receive medical treatment reserved for those on Elysium. Dave Eggers conjures up an apparently eutopian hi-tech company, The Circle, in his novel of the same name, representing how new technologies manipulate data and images for economic, social and political control. Spike Jonze’s film Her explores the relationship between surveillance and intimacy through the interaction between a human and an operating system. As with Eggers’ The Circle, Her investigates how data confuses definitions of identities as it allows for the fusion of surveillance and intimacy. These novels and films suggest some of the ways in which new forms of surveillance promise or threaten to fashion the worlds of the future. As with all such texts, they suggest options and present narratives and characters that enable readers and viewers to think and act so that the future approximates the eutopian rather than the dystopian.

The Cost

The first indications of future trouble are identified. For most of history, new medicines arise from nature but this approach came into question as evidenced by the development of the cancer drug Taxol. As understanding of biology and chemistry incraesed, a degree of over-confidence arose as researchers assumed that new technologies would allow them to predict the most effective medicines. These changes were a response to an environment confronting twin pressures in the form of rising generic medicines coupled with ever more costly research and development activities needed to develop new products to replace those devastated by generic competition. These issues were exacerbated by a rising dependence upon “blockbuster” products, which conveyed short-term revenues but inevitably needed to be replaced by even more profitable products once generic competition intervened. Dependence on blockbusters was exemplified by the story of ulcer medicines, which was disrupted by an audacious study by an investigator who used himself as a Guinea pig to make his point. As such risks increased, the industry became more cautious and the race was on to make incremental improvements upon competitors’ products. All the while the cost of developing new medicines continued to escalate.

Purpose Energy losses in a timing chain drives are caused by friction in chain-rail contacts. To improve the efficiency, the Chair of Machine Elements and Transmission Technology at the University of Kaiserslautern developed various experimental and simulative analysis tools as a part of the German Research Foundation (DFG)-funded 1551 priority program and the DFG Collaborative Research Centre CRC 926. With these tools, various approaches for improving the efficiency were investigated. This paper aims to illustrate the approaches and present the results achieved within the framework of the above-mentioned priority program. Design/methodology/approach A towed cylinder head test rig is used for efficiency tests on timing chain drives. In addition to the experiments, a multi-body simulation model of the timing drive was developed and used. Findings It was possible to find positive approaches to reduce friction power by adapting the chain tensioning force as required. This was ensured for both the stationary operating points and the transient operating processes. An efficiency improvement of up to 10 per cent could be detected. Furthermore, a possibility was found to improve the frictional power by a targeted lubrication of the chain-rail contact. Here, the efficiency could be improved by 5-6 per cent. In addition, various structures were examined on a microscopic and macroscopic level. Neutral to negative results were achieved here. Originality/value This paper makes a contribution to improve the energy efficiency of timing chain drives. Different approaches have been investigated and evaluated.
