Halon is being removed from all Esso facilities in accordance with Victorian Environment Protection Legislation for the control of ozone depleting substances. The phasing out of halon as a fire protection system required critical evaluation of available alternatives for protection of turbine machinery and switchgear rooms.Esso Australia Ltd., having evaluated and tested a range of available halon replacement systems, has selected a European manufactured water mist as the preferred alternative for fire protection of turbine machinery enclosures. The system selected required significant modifications from the vendor's standard configuration in order for it to be applied to the offshore environment, be accepted by turbine Original Equipment Manufacturers and achieve independent third party certification. Water mist cannot be applied in all situations to replace halon, with an inert gaseous agent required for the protection of switchgear rooms and for flare snuffing.This paper discusses the issues associated with the selection and installation of this new technology and the lessons learnt. It also discusses issues associated with the evaluation, testing, design and installation of over 80 systems on 14 offshore platforms and two onshore plants.

Modern high-pressure water mist systems are an advanced choice for rotating machinery fire protection. High-pressure water mist systems can provide: • Proven extinguishing efficiency, • Proven capability to protect equipment from thermal stresses, • Tolerance to poor enclosure integrity, • A safe and reliable alternative to gaseous systems, and • An environmentally friendly alternative to dry chemicals, halons and halon alternatives. Generally, the systems have total flooding design, which is the most appropriate for protecting rotating equipment in their purpose-built enclosures. Fine water mist with a specific application rate, droplet size distribution and high discharge momentum is used to fill the enclosure quickly and completely. For all fire protection systems, third party testing and appraisal is important. FM and VdS have approved gas turbine fire protection systems for enclosures up to 500m3, while systems for enclosures up to 3300 m3 are (2004) within approval process. This paper explains the water mist system basic terminology and fundamentals. The paper then discusses system design requirements and features. In the end, health and safety, as well as environmental aspects are reviewed.

Information Technology as a new Technology has been used in businesses from small company until multinational company in almost all industries. IT role as an enabler and differentiation factor separating success company from average company. IT need people to build, operate, maintain and support the systems, hence expect the new hire to immediately contribute from the first day they join the company. The industry define the needs for Information Technology competence and expect Education Institution as one of IT resource work hard to design their program study to fulfill the needs for Information Technology graduates, yet the industry still struggle to succeed in hiring fresh graduate to fill the IT position. Information Technology Training Institution can be an alternative to improve the education result. Also certification on Information Technology competence from third party or independent body might be used as a standard for both Industry and Education. This paper will report literature review several previous paper about all of the above.

Abstract Managed care organizations must establish formal processes for the evaluation of new technology, procedures, and drugs to enhance the quality of health care delivered and to support coverage and utilization decision making. Evidence-based research and the results of controlled clinical trials are the preferred sources of outcomes data to support the safety and effectiveness of the technology, procedure, or drug under review. In addition to extensive literature review, the opinion of experts in the field and acceptance by the medical community are considered. Assessments of new technology and drugs are available for purchase from several vendors, and managed care organizations can adopt or modify such evaluations to develop medical coverage policies. The research community can assist third-party payers by conducting studies on practices that might lead to substantial, rather than marginal, improvement in health, pay particular attention to study design when randomized controlled studies are not possible, and include functional and behavioral measures in analysis of outcomes.

Governments provide a wide range of services, and the digital economy provides both threats and opportunities in this sector. The Transport Accident Commission (TAC) is a compulsory, government owned and operated insurance scheme for third-party, no-fault liability insurance for transport accident victims, operated in Victoria, Australia. E-business has now been widely used in all sectors from small business (Loane, McNaughton, & Bell, 2004) to emerging economies (Li & Chang, 2004), and in very different industry sectors (Cagno, Di Giulio, & Trucco, 2004; Golden, Hughes, & Gallagher, 2003). Major steps forward and applications have occurred in retailing (Leonard & Cronan, 2003; Mackay, Altmann, & McMichael, 2003; Starr, 2003). Applications need to be highly customized as the business-to-consumer (B2C) and business-to-business (B2B) environments are very different, and requirements of industries such as retailing and mining, and indeed government, differ substantially (Carter, 2003; He & Lung, 2002; Rotondaro, 2002). Government provides a particularly different environment for e-business applications because government services are often delivered in monopoly circumstances, with no real profit motive behind them. At the height of the technology boom in October 1999, Tony Marxsen joined the TAC as head of IT to develop a new IT outsourcing contract for the organization as the current 5-year contract was due to end in July 2000. He quickly realized that the TAC IT systems were out of date, lacked IT process integration, and were constraining improvement in business processes, and that no significant investments had been made for some time. Renewing or redesigning the outsourcing contract, the basis for which he had been employed, would only be a short-term solution. The problem was that the cost of new infrastructure would be high, and return on technology investment would mainly be realized from redesigned business processes enabled by the new technology. Tony wanted to propose a business transformation, with process changes as well as significant investment in IT infrastructure. Together, these would take the TAC from 1970s technology into the 21st century. The problem was that their (investments in such transformation) payoffs are not easily and quickly achieved. Their value does not come from installing the technology; it comes from changing both operating and management processes—perhaps operating and managing cultures too. (Ross & Beath, 2002, p. 53) Tony knew he would have to win the support of the board and senior management, but he could not immediately give them a concrete business case for the investment. He also knew that any infrastructure investment had to be linked with a major process-improvement initiative from the start to avoid the double investment of building new applications to support old processes, and then undertaking major modifications or even replacement when the need for improvement became obvious to the board and management team. He compared investing in IT infrastructure to rewiring and replumbing your house: as far as visitors are concerned, there’s no visible difference, everything’s behind the walls, but as the owner you get the benefits of things like cheaper electricity and water bills because of efficiencies in the new redesigned systems. The problem is convincing people that they will get these results in the future, but that they need to hand over the money now, when there’s no hard evidence for the benefits they’ll get, just a bunch of assumptions and no guarantees. It’s a big ask for any Board. (Marxsen, personal communication, September 4, 2003) Tony knew that the first hurdle he would have to overcome would be getting the board to agree to give him the opportunity to put together a team to develop a business case for the board’s further consideration.

The autonomous industry has rapidly grown for self-driving cars. The main purpose of autonomous industry is trying to give all types of security, privacy, secured traffic information to the self-driving cars. Blockchain is another newly established secured technology. The main aim of this technology is to provide more secured, convenient online transactions. By using this new technology, the autonomous industry can easily provide more suitable, safe, efficient transportation to the passengers and secured traffic information to the vehicles. This information can easily gather by the roadside units or by the passing vehicles. Also, the economical transactions can be possible more efficiently since blockchain technology allows peer-to-peer communications between nodes, and it also eliminates the need of the third party. This chapter proposes a concept of how the autonomous industry can provide more adequate, proper, and safe transportation with the help of blockchain. It also examines for the possibility that autonomous vehicles can become the future of transportation.

Cloud Computing is a diverse research area that encompasses many aspects of sharing software and hardware solutions, including computing and storage resources, application runtimes or complex application functionalities. In the supply of any goods and services, the law gives certain rights that protect the consumer and provider, which also applies for Cloud Computing. This new technology also moves functions and responsibilities away from local ownership and management to a third-party provided service, and raises several legal issues, such as data protection, which require this service to comply with necessary regulation. In this chapter the author investigates the revised legislation of the European Union resulting in the General Data Protection Regulation, which will be used to set up the new European Data Protection Framework. The author gathers and summarizes the most relevant changes this regulation brings to the field of Clouds, and draws relations to the previous legislation called the Data Protection Directive currently in force.

In the past few years, DNV has been involved in a variety of projects related to marine energy converters. All projects have been characterised for the handling of technical uncertainties due to the application of new technology or proven technology in different area of application. A systematic approach based on the DNV RP-A203 Qualification of New Technology [1] was applied combined with the Guidelines for Design and Operation of Wave Energy Converters [2] to steer the third party activity, but, more importantly, to allow developers to systematically identify and deal with the risks in a rational manner with traceability of decisions throughout the development of the energy converter. From the very start of our engagement, it was clear that the handling of technical uncertainties was affected, not only by the technical barriers, but also by financial and time constraints. The establishment of the safety and functional targets to be achieved by the energy converter are to be based, not only on the safety and asset integrity aspects, but also on the financial / business model. The experience of using the Qualification process and the Guidelines on these projects, achieving the right balance between the constraints, handling of uncertainties, financial targets and safety and functional requirements, are briefly described in this paper as well as the future steps to be taken to improve the process and consolidate the experience so far. In this paper, it is also addressed the use of the DNV OSS-312 [3] on the certification process of marine energy converters.

AbstractGeneral-purpose computing on graphics processing units (GPGPU) is dramatically changing the landscape of high performance computing in astronomy. In this paper, we identify and investigate several key decision areas, with a goal of simplifying the early adoption of GPGPU in astronomy. We consider the merits of OpenCL as an open standard in order to reduce risks associated with coding in a native, vendor-specific programming environment, and present a GPU programming philosophy based on using brute force solutions. We assert that effective use of new GPU-based supercomputing facilities will require a change in approach from astronomers. This will likely include improved programming training, an increased need for software development best practice through the use of profiling and related optimisation tools, and a greater reliance on third-party code libraries. As with any new technology, those willing to take the risks and make the investment of time and effort to become early adopters of GPGPU in astronomy, stand to reap great benefits.
