In this paper, we present a new intensity based technique for recovering depth information from two or more images. Our method uses planar patches to approximate 3-D surfaces. In order to recover the depth information, the view-line constraint and the imaging geometry are introduced. The view-line constraint is used to restrict the position of a planar patch. From the constraint we can get the ...

Abstract:In telecommunications, there are several types of microstrip antennas, the most common of which is microstrip patch antenna. Patch antennas are also relatively inexpensive to manufacture and design because of simple 2D physical geometry. In this paper Two L slits are introduced at the both edge of the patch to reduce the resonant frequency. The proposed antenna is developed to operate ...

A novel broadband multilayer-layer coaxial coupled patch antenna is proposed. A simple patch geometry that is based on a rectangular patch which is place above the ground at a height (h1 +h2 ) fed by oaxialc coupled is introduced in this paper. A new resonant mode is excited using this novel patch structure. The results shows that the bandwidth is 450 to 750 GHz (S11<–10dB), larger than 40%. Th...

recent developments in the area of smart structures indicate that variable geometry / stiffness truss network is of fundamental importance in designing smart transformable structures and systems for space applications. this paper presents the conceptual design and dynamic modeling of a cooperative re-configurabel dual-arm robotic structure called dual-arm cam-lock manipulator. the manipulator i...

In this paper a new geometry of circularly polarized patch antenna is proposed with improved bandwidth. The radiation performance of proposed patch antenna is investigated using IE3D simulation software and its performance is compared with that of conventional circular patch antenna. The simulated return loss, axial ratio and impedance with frequency for the proposed antenna are reported in thi...

Micro strip patch antennas are widely used in compact, conformal and lowcost wireless applications due to its advantages over conventional antenna. Literature study of last few decades of micro strip patch antenna (MPA) shows that the different techniques are used to design a small size micro strip patch antenna. In this paper survey is conducted on different antenna designing methods like E sh...

Isogeometric analysis allows to define shape functions of global C continuity (or of higher continuity) over multi-patch geometries. The construction of such C-smooth isogeometric functions is a non-trivial task and requires particular multi-patch parameterizations, so-called analysis-suitable G (in short, AS-G) parameterizations, to ensure that the resulting C isogeometric spaces possess optim...

Electrophysiology is a central tool for measuring how different driving forces (e.g., ligand concentration, transmembrane voltage, or lateral tension) cause a channel protein to gate. Upon formation of the high resistance seal between a lipid bilayer and a glass pipette, the so-called "giga-seal", channel activity can be recorded electrically. In this article, we explore the implications of gig...
