  • HSS Manufacturing Methods The transformation of steel strip into hollow structural sections (HSS) is the result of operations including forming, welding and sizing. Currently three methods are being used in North America for the manufacture of HSS. These methods, including two ERW methods and an SAW method, are described below. Both ERW methods meet ASTM A 500 and CSA G-40.21 requirements for the manufacture of HSS, and the ERW sizes included in this publication may be produced to either standard. The SAW method is not included as a manufacturing process in the ASTM or CSA specification.

  • Circuit connections to the DAQ require a cable and a facility for connecting to individual pins. An efficient system is based on a National Instruments Connector Block (CB-68LP) and a basic circuit board as shown here. Connections to the circuit board from the connector block are made one time. The two resistors of the circuit are connected to output channels 0 and 1, respecively. Thus, for example, Chan0_out, as noted, is dedicated to the top strip on the circuit board. The bottom top strip is associated with Chan0_in, and so forth....

  • A fairly simple method of converting a model into triangle strips is sometimes known as greedy tristripping.One of the early greedy algorithms was developed for IRIS GL which allowed swapping of vertices to create direction changes to the facet with the least neighbors.

  • Manufacturing was what I had always done and it was fading fast. The numbers of time-served manufacturing professional compared to the decreasing numbers of vacancies made it a daunting prospect. It did mean, though, that you had to be good to succeed. But when supply far out-strips demand, the currency becomes devalued. Even the highest quality items become a commodity and prices fall dramatically. Although I was still winning through, my final sojourn at British Steel was the last straw. I had the choice of either re-training or going it alone. For the quality of life, the autonomy and...

  • Ưu điểm chính của kỹ thuật này là khả năng dung lỗi cao và tốc độ truy xuất cao bởi sử dụng nhiều kênh I/O.Volume RAID-5. Tương tự như volume striped nhưng RAID-5 lại dùng thêm một dãy (strip) ghi thông tin kiểm lỗi parity. Nếu một đĩa của volume bị hỏng thì thông tin parity ghi trên đĩa khác sẽ giúp phục hồi lại dữ liệu trên đĩa hỏng. Volume RAID-5 sử dụng ít nhất ba ổ đĩa (tối đa là 32).
