Through the research on the evaluation method of bill of quantities valuation mode, we found that the traditional manual review has been completely unable to meet the requirements of listing the bid assessment. Besides, the paper studied on invoicing system, evaluation methods and invoicing software, analyzed the feasibility and necessity of the electronic auxiliary evaluation, expounded the application...
The intension and developments for metrology of Initiators & Pyrotechnics were summarized in this paper. The important significance for metrology of Initiators & Pyrotechnics was clarified impelling the progress of Initiators & Pyrotechnics technology, insuring the veracity and consistency of engineering characteristic quantity value as well as improving its safety. The development...
This paper is about safety assessment for the pre-hydrogenation reactor with a surface crack. The pre-hydrogenation reactor contains a weld-crack defect. Safety assessment of in-service pressure vessel is based on the principle of "fit-for-service". The author has safety assessment in accordance with Chinese national standard Safety Assessment for In-service Pressure Vessels Containing Defects...
Electronic Double-Layer Capacitors (Supercapacitors) have energy densities that are roughly two orders of magnitude greater than their traditional capacitor counterparts. The high charge and discharge rate, long life, low internal resistance, high output power, and improved energy density of the super caps has introduced the possibility of these devices being used in portable electronics. Supercapacitors...
Internet is penetrating into every aspect of people's life. It brought forth significant influences on us, involving negative and positive. Among these influences, the passive effects of online eroticism needed especially attention. The current paper aimed to explore the appraisal index of erotic information to offer foundations for online culture safety management. Empirical study indicated that...
Due to their reconfigurability and their high density of resources, SRAM-based FPGAs are more and more used in embedded systems. For some applications (Pay-TV,Banking, Telecommunication ...), a high level of security is needed. FPGAs are intrinsically sensitive to ionizing effects, such as light stimulation, and attackers can try to exploit faults injected in the downloaded configuration. Previous...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
This paper discusses the manner in which cinema buildings of the 20th century represent both an important physical record of society, and a challenge in terms of representing a complex range of historical, cultural, economic and physical data sets.The paper provides an overview of visualisation techniques which are appropriate to the subject, and provides a case study taken from the city of Aberdeen...
A selection is presented of fiber-optic and micro-optic devices that have been designed and tested for guaranteeing the quality and safety of typical foods, such as extra virgin olive oil, beer, and milk. Scattered colorimetry is used to authenticate various types of extra virgin olive oil and beer, while a fiber-optic-based device for UV-VIS-NIR absorption spectroscopy is exploited in order to obtain...
The introduction of Directive 94/9/EC in Europe marked the first full-coverage analysis of all possible ignition sources. Against the background of the well-known standards for electrical equipment, an additional series of standards EN 13463-x was hurriedly created that takes the new aspects into account while relying on the successful application of existing types of protection.
Energy is the bedrock of our daily lives and industry. Now is the time that industry, government and academia must join together and examine highly independent, fully environmentally considerate and rational energy systems. In this presentation, recent Japanese policy will be introduced focusing on new national energy strategy. Looking at future technology trends, it is probable that, in the case...
Some local codes require electrical equipment to be investigated by a recognized inspection agency. Listing by Underwriters' Laboratories is a widely accepted solution in the United States. This paper relates some of the procedures, tests, and restrictions that are placed upon the equipment manufacturer to receive and maintain the UL listing for a power supply. Underwriters' Laboratories Inc. (UL)...
