  • 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 field of biomechanics has been evolving from the times of ancient Greeks. Recent publications and research in biomechanics sky rocketed as the field of traditional biomechanics is creating new opportunities in diagnostics, therapy, rehabilitation, motion preservation, kinesiology, total joint replacement, biomechanics of living systems at small scale, and other areas.

  • Firms obviously choose to insure risk-averse workers when the premium is fair. They may choose to do so even if the premium is slightly higher than the expected cost. Nevertheless, if a firm’s expected health cost is significantly lower than the premium, it may choose not to offer insurance to workers. As we have just observed, small firms have higher variances in health costs. Hence, relative to large firms, more small firms will have expected costs that are significantly below the offered premium, and they choose not to offer insurance to workers.

  • The function of the pelvic floor is fundamentally influenced by the behaviour of several organs and the organ-linked processes. The aim of this work is to study the properties and changes of the women’s pelvic floor. The motive arises from the fact that pelvic floor dysfunctions badly influence the quality of life. The loss of the proper function in the pelvic floor results in a wide range of problems from asymptomatic and anatomic defects to vaginal eversion.

  • The fabricated pores were found to be stable at ambient conditions and in water. The pore-size tuning technique was further tested on holes fabricated using a different process. In agreement with Chen et al. 5 ,we find that a focused electron beam with a spot size of a few nanometres can be used to drill holes in thin free-standing SiO2 membranes,with an estimated thickness of about 10 nm (Fig. 3a). Figure 3b,c shows a pore that has been drilled using an electron-beam intensity above 1×108 Am–2 .

  • Many parsing techniques including parameter estimation assume the use of a packed parse forest for efficient and accurate parsing. However, they have several inherent problems deriving from the restriction of locality in the packed parse forest. Deterministic parsing is one of solutions that can achieve simple and fast parsing without the mechanisms of the packed parse forest by accurately choosing search paths. We propose (i) deterministic shift-reduce parsing for unification-based grammars, and (ii) best-first shift-reduce parsing with beam thresholding for unification-based grammars.
