An internal compact printed loop antenna with matching element is presented for laptop applications. Bending to the printed loop structure is employed to reduce the size of antenna. A matching element is used at backside of the substrate to enhance the bandwidth of the antenna. The matching element is of rectangular shape with inverted U shape slot in it. The proposed antenna with wideband char...

SRW/U (the Search/Retrieve Webservice) and OAI (Open Archives Initiative) are both modern information retrieval protocols developed by distinct groups from different backgrounds at around the same time. This article sets out to briefly contrast the two protocols' aims and approaches, and then to look at some novel ways in which they have been or may be usefully co-implemented. While using SRW a...

We report improved measurements for the nu 6 antisymmetric stretch fundamental and observation of the (nu 6 + nu 15)-nu 15 and (nu 6 + 2 nu 15)-2 nu 15 hot bands of the linear C9 carbon cluster by direct absorption diode laser spectroscopy of a supersonic carbon cluster beam. Analysis of these bands characterizes C9 as a semirigid molecule with a bending potential similar to that of C5 and fur...

The introduction on large scale of high strength materials in automotive industry provided the possibility to reduce weight and produce safer cars. But at the same time these materials yield more springback than deep drawing steels. This can lead to problems designing the right tools for the forming process. This paper presents a method for the optimization of sheet metal forming parameters in ...

Laser tube bending is a flexible forming process. Two irradiation methods of axial and circumferential scanning are generally used to form metal tubes. The two most important disadvantages of circumferential scanning are its lower bending angle and the time interval required between each scan for cooling purpose. In this research, a novel cooling strategy during laser tube bending with circumfe...

Speakers of a given language vary with respect to their acoustics, articulation, and motor commands. This variation is driven by a variety of influences, such as emotional states, communicative interaction, and individual properties of the vocal tract. In this work we focus on the latter. First, we build speaker-specific biomechanical tongue models. Second, we discuss the impact of the relative...

In this paper, we consider rods whose thickness vary linearly between and . Our aim is to study the asymptotic behavior of these rods in the framework of the linear elasticity. We use a decomposition method of the displacement fields of the form u = Ue + ū, where Ue stands for the translation-rotations of the cross-sections and ū is related to their deformations. We establish a priori estimates...

Soft actuators are receiving increasing attention from the engineering community, not only in research but even for industrial applications. Among soft actuators, fibre-reinforced Bending Fluidic Actuators (BFAs) became very popular thanks to features such as robustness and easy design and fabrication. However, an accurate modelling of these smart structures, taking into account all the nonline...

This paper develops an efficient, physically based shape manipulation technique. It defines a 3D model with profile curves, and uses spine curves generated from the profile curves to control the motion and global shape of 3D models. Profile and spine curves are changed into profile and spine wires by specifying proper material and geometric properties together with external forces. The underlyi...

This work concerns an assessment of the behavior of infilled frames. The feasibility of possible immediate implementation of some recent developments both in analysis and design of infilled frames for practical design is investigated. It is now widely recognized that masonry infill panels used in reinforced concrete (R/C) frame structures, significantly enhance both the stiffness and the streng...
