  • Concrete has been in use as a primary building material since Roman times. As it is strong in compression but weak in tension, it was used in arches, vaults and walls where it is stressed principally in compression. In the mid-nineteenth century, it was discovered that iron and later steel bars could be embedded in the concrete, effectively giving it tensile strength. This allowed it to be used in beams and slabs, where it worked in bending. Buildings, bridges, retaining walls and many other structures were made in this reinforced concrete.

  • The bremsstrahlung beam with energy end point of 65M eV created when the e− beam with energy of 65M eV irradiated to thin wolfram target was used to irradiate to TiO2 sample in order to make the 46 Ti (γ, pn)44m,g Sc reaction. The gamma spectrum of Sc44m,g was analyzed by the gammavision spectrometry with HPGe detector at linear accelerator laboratory in POSTECH, Korea.

  • Determine midspan deflection of beam. Ignore the self weight of the beam. Create the model as follows: 1. From the File menu, choose New Model From Template. Select the Beam template in the upper left hand corner. Set the number of spans to one. 2. Define the frame section properties. 3. Apply the loads to the beam. 4. Use the Divide Frames option in the Edit Menu to break the beam into two elements with a joint at the center.

  • The term “CMOS MEMS” most often describes pro- cesses that create microstructures directly out of the metal/ dielectric interconnect stack in foundry CMOS. The metal- lization and dielectric layers, normally used for electrical interconnect, now serve a dual function as structural layers. For example, the suspended n-well of Figure 3(d) is consid- ered CMOS MEMS, since its beam suspension is made from the CMOS interconnect stack. There is significant motivation for making MEMS out of CMOS. Leveraging foundry CMOS for MEMS is fast, reliable, repeatable, and economical.

  • 3D printers are the fastest growing type of personal manufacturing machine, and perhaps the best publicized by the popular press. 3D printers use as an additive process, meaning they make objects by systematically depositing a chosen raw material in layers. Somewhat similar in concept to that of an inkjet printer that orchestrates different colored print cartridges to form an image onto paper, the most common household 3D printing process involves a “print head” that works with any material that can be extruded, or squirted through a nozzle.

  • The size and principal characteristics of a new ship are determined primarily by its mission or intended service. In addition to basic functional considerations, there are requirements such as stability, low resistance, high propulsive efficiency, and navigational limitations on draft or beam, all of which influence the choice of dimensions and form. Within these and other basic constraints, the ship’s structure must be designed to sustain all of the loads expected to arise in its seagoing environment.

  • Flow cytometry is a technology that simultaneously measures and analyses multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream through a beam of light. The properties measured include a particle’s relative size (represented by forward angle light scatter), relative granularity or internal complexity (represented by right-angle scatter), and relative fluorescence intensity.

  • This paper proposes a method for incrementally understanding user utterances whose semantic boundaries are not known and responding in real time even before boundaries are determined. It is an integrated parsing and discourse processing method that updates the partial result of understanding word by word, enabling responses based on the partial result. This method incrementally finds plausible sequences of utterances that play crucial roles in the task execution of dialogues, and utilizes beam search to deal with the ambiguity of boundaries as well as syntactic and semantic ambiguities. ...
