[en] The CMS Data Acquisition System is designed to build and filter events originating from 476 detector data sources at a maximum trigger rate of 100 KHz. Different architectures and switch technologies have been evaluated to accomplish this purpose. Events will be built in two stages: the first stage will be a set of event builders called FED Builders. These will be based on Myrinet technology and will pre-assemble groups of about 8 data sources. The second stage will be a set of event builders called Readout Builders. These will perform the building of full events. A single Readout Builder will build events from 72 sources of 16 KB fragments at a rate of 12.5 KHz. In this paper we present the design of a Readout Builder based on TCP/IP over Gigabit Ethernet and the optimization that was required to achieve the design throughput. This optimization includes architecture of the Readout Builder, the setup of TCP/IP, and hardware selection

[en] The construction industry is one of the main Palestinian industries as itis considered an essential requirement and a major foundation for economicactivities. A key factor to a successful construction project is to completethe project without the existence of claims. The objective of this paper isto identify the rank causes of claims in the construction industry from theperspective of local clients. Quantitative method was used in this research.The questionnaire was sent to120 clients in the Gaza Strip and 101 validresponses were received and analyzed. The results found the main causes ofclaims are: border closures, awarding bid to lower bidder, road blockage,difficulties to pass between cities and governorate, resident's interferenceduring project implementation and unexpected increase in material prices.Border closures found to be a political problem which is not easy to resolve.The findings indicate that owners may not award the contract to the lowestbidder. During project preparation and design, owners need to coordinate withthe local residents of the area to inform them about the benefits of theprojects. The findings reveal that owners may assist contractors in removingobstacles of the project sites to avoid delays. Finally, the findings will beuseful in removing obstacles of the project sites to avoid delays. Finally,these findings will be useful for international engineering and constructioncompanies seeking a share in the Palestine market. (author)

[en] The BaBar experiment is the particle detector at the PEP-II B-factory facility at the Stanford Linear Accelerator Center. During the summer shutdown 2002 the BaBar Event Building and Level-3 trigger farm were upgraded from 60 Sun Ultra-5 machines and 100MBit/s Ethernet to 50 Dual-CPU 1.4GHz Pentium-III systems with Gigabit Ethernet. Combined with an upgrade to Gigabit Ethernet on the source side and a major feature extraction software speedup, this pushes the performance of the BaBar event builder and L3 filter to 5.5kHz at current background levels, almost three times the original design rate of 2kHz. For our specific application the new farm provides 8.5 times the CPU power of the old system

[en] The performance of the new Cathode Strip Chamber segment builder algorithm with simulated TeV muons is considered. The comparison of some of the main reconstruction characteristics is made. Some case study events are visualized in order to illustrate the improvement that the new algorithm gives to the reconstruction process.

Hedgewood Properties teamed with Building America's IBACOS Consortium and Southface Energy Institute to build a house with a Home Energy Rating Systems (HERS) level of 90

[en] A global supply strategy has been placed by Westinghouse in order to face the current and future constructions. And in this way, Westinghouse will be able to take advantage of benefit of Local Supply. this article shows the Westinghouse Global Supply Strategy, Local Supply considerations, the current state of supplier calcifications, and finally Memorandums of Understanding and Alliances agreed with local suppliers around the world to provide a suitable solution for the new construction needs.

[en] The CMS Data Acquisition system is designed to build and filter events originating from approximately 500 data sources from the detector at a maximum Level 1 trigger rate of 100 kHz and with an aggregate throughput of 100 GByte/s. For this purpose different architectures and switch technologies have been evaluated. Events will be built in two stages: the first stage, the FED Builder, will be based on Myrinet technology and will pre-assemble groups of about 8 data sources. The next stage, the Readout Builder, will perform the building of full events. The requirement of one Readout Builder is to build events at 12.5 kHz with average size of 16 kBytes from 64 sources. In this paper we present the prospects of a Readout Builder based on TCP/IP over Gigabit Ethernet. Various Readout Builder architectures that we are considering are discussed. The results of throughput measurements and scaling performance are outlined as well as the preliminary estimates of the final performance. All these studies have been carried out at our test-bed farms that are made up of a total of 130 dual Xeon PCs interconnected with Myrinet and Gigabit Ethernet networking and switching technologies

[en] The quality assurance (QA) and quality control (QC) is a very important work in the nuclear engineering. This paper starts with how to establish quality assurance system of nuclear engineering construction phase, then introduces several experiments and techniques such as the implementation of quality assurance program, the quality assurance and quality control of contractors, the quality surveillance and control of supervisory companies, quality assurance audit and surveillance of builders.

[en] As the Building America Program has grown to include a large and diverse cross section of the home building industry, accurate and consistent analysis techniques have become more important to help all program partners as they perform design tradeoffs and calculate energy savings for prototype houses built as part of the program. This document illustrates some of the analysis concepts proven effective and reliable for analyzing the transient energy usage of advanced energy systems as well as entire houses. The analysis procedure described here provides a starting point for calculating energy savings of a prototype house relative to two base cases: builder standard practice and regional standard practice. Also provides building simulation analysis to calculate annual energy savings based on side-by-side short-term field testing of a prototype house

[en] Many tasks typical for High Energy Physics such as simulation, event display, maintenance of the geometry database of an experiment, require input of geometrical data. To simplify the process of preparation of such kinds of data an interactive graphics tool GBuilder is being developed. Definition of the geometry model in GBuilder is based on the Constructive Solid Geometry approach where objects are defined using boolean operations on basic shapes. To provide parameterization of the model arithmetic expressions may be used in place of numbers. A wide list of predefined materials is also available. Different drivers allow to output the geometry model in a form suitable for specific simulation or visual analysis tools
