Safety is always the number one focus of the pipeline industry. This paper will discuss how Double Block & Bleed (DB&B) maximizes safety during a pipeline isolation. In addition to safety, DB&B also maximizes project efficiency, which results in minimizing project and maintenance costs. The goal of DB&B for both safety and efficiency is to approach 100 percent success in achieving a seal with no detectable seepage. Pipeline isolations are frequently utilized for maintenance such as replacement of leaking block valves, cut out and repair of third party damage, and cut out and replacement of imperfections identified during inline inspection runs. This paper will begin with a review of laboratory testing and calculation of DB&B efficiency, followed by one or more field case studies.

Models pertaining to the antiquity and continuity of Eurasian human populations and their cultural traditions have been revised in recent years as a result of novel inter-disciplinary research. In this third installment of the DFG Center for Advanced Studies Series, experts provide new field case studies, reviews, and original research on bio-cultural connections in Eurasia since the Paleolithic.

The One

This paper analyses the recent phenomenon of private/public partnerships (PPPs) in the ICT sector of the developing world. The partners may come to these projects with divergent motivations: profit on the one hand and the provision of public services on the other, but at the end of the day, the interests of the partners that are symbiotic can – and indeed should – be aligned to ensure successful long-term projects. To investigate what can be done to promote successful and sustainable PPPs, this paper extends the traditional two-actor analysis to include both a third-party non-profit-oriented facilitating organization and the technology recipients that are the targets of these projects. Following an overview of the current state of PPPs in the developing world, the paper provides two case studies, based in Vietnam, where all four of the above-mentioned stakeholders were involved. The cases reveal important success factors that can be applied to future PPPs in the ICT sector.

The Way

Cloud computing is a new breed of service offered over the Internet, which has completely changed the way one can use the power of computers irrespective of geographic location. It has brought in new avenues for organizations and businesses to offer services using hardware or software or platform of third party sources, thus saving on cost and maintenance. It can transform the way systems are built and services delivered, providing libraries with an opportunity to extend their impact. Cloud computing has become a major topic of discussion and debate for any business or organization which relies on technology. Anyone connected to the Internet is probably using some type of cloud computing on a regular basis. Whether they are using Google’s Gmail, organizing photos on Flickr, or searching the Web with Bing, they are engaged in cloud computing. In this chapter, an attempt has been made to give an overview of this technology, its connection with libraries, the models in which libraries can deploy this technology for providing services and augment the productivity of library staff and case studies.

Exoskeleton Design

The past few decades have witnessed a rapid explosion in research surrounding robotic exoskeletons due to their promising applications in medicine and human performance augmentation. Several advances in technology have led to the development of more energy efficient and viable prototypes of these devices. However, despite this rapid advancement in exoskeleton technology, most of the developed devices are limited to laboratory testing and a very few of them are commercially available for human use. This chapter discusses the advances in various constituting technologies including actuation, sensing, materials, and controls that made exoskeleton research feasible. Also presented are case studies on two state-of-the-art robotic exoskeletons, Harmony and Maestro, developed for rehabilitation of the upper body. The chapter concludes with a discussion on the ongoing challenges in exoskeleton design and ethical, social, and legal considerations related to the use of these devices and the future of exoskeletons.

Substantial Impact

AbstractAlthough it is a mistake to believe that the material traces left by a composer's practice can help us to properly reconstruct the creative process, compositional sketches may throw light on it. Nevertheless many such accounts take their respective case studies as isolated objects that are, unfortunately, sometimes decontextualised from the whole record of their authors. Ethnography potentially offers a better methodology and auto-ethnographic accounts, third party observations, and mixtures of these approaches have already been applied to contemporary music. This article aims to combine both these approaches in a discussion of a recent compositional project at IRCAM, carried out by a team of three people. I consider how the previous artistic experiences and achievements of these people, jointly and separately, have had a substantial impact on their shared project. In addition, as the case study had a scientific underpinning, I comment on the cognitive bridge that the composer had to build between scientific and musical conceptions.

Correct Design

Correct design and layout of the SCR BYPASS SYSTEM is critically important to the efficiency and operation of power plants. Utilities have even had to consider closing down plants that could not efficiently operate their Bypass Systems. Numerous gas path configurations are available, which vary considerably based on site and space limitations, construction lifting capabilities and site construction limitations, as well as other key considerations specific to each plant site. This technical paper discusses a number of arrangements, technical selection and layout criteria. This paper discusses case studies and design details of approximately 20,000 MW of successful bypass system equipment which improve system performance, reduce pressure drop, reduce abrasive wear, substantially minimize maintenance costs and simplify operating requirements.
