Defense applications ofspace-borne laser radar require a sensor that can point to a large number of targets in rapid succession and over a wide field of regard. By using a fullaperture, mechanically steered flat mirror, the requirements for high-acceleration beam steering can be met. Three alternative mirror structures were designed and their perfonnance was evaluated through computer simulatio...

In various applications, it is common to use thin beam-like structures, made of plastic or fibre-reinforced materials, as well components such cables. They are flexible, and the most form deformation bending, but they can also be stretched torqued. Due their structural composition, a coupling between different loading directions exists. This especially pronounced for cables, where interact with...

Introduction: Panoramic view as a routine dental radiograph has an important role in diagnosis of other facial abnormalities accompanied with dento- alveolar structures. In this case presentation, we discuss this subject and also the efficacy of cone-beam computed tomography in localization of foreign body in complex anatomy of nasal cavity.

The role of parallel fibers (PFs) in cerebellar physiology remains controversial. Early studies inspired the "beam" hypothesis whereby granule cell (GC) activation results in PF-driven, postsynaptic excitation of beams of Purkinje cells (PCs). However, the "radial" hypothesis postulates that the ascending limb of the GC axon provides the dominant input to PCs and generates patch-like responses....

This paper present the experimental result of flexural behavior Hybrid Fiber Reinforced Polymer (HFRP) concrete beams reinforced with Glass (GFRP) rebars and steel bars. experiment is conducted aim replacing reinforcement GFRP to reduce risk corrosion in structures. The data presented this study obtained by conducting test on four HFRP various PVA fibre dosage 0%, 0.25% 0.5% one Pure FRP beam. ...

Abstract. The possibility of creating vacuum robotics based on the polymer structures irradiated by an electron beam, in particular, fibers, which provide high functional flexibility and a variety states, is discussed. using fibers as different types MEMS-like electromechanical elements demonstrated - from elastic cantilevers to springs that change their state under beam. Experimentally proved ...

Experiments to study beam dynamics for Relativistic Klystrons (RK) are being performed with a 1-MeV, 600-A induction accelerator beam. The RK is a RF Power source based on induction accelerator technology and conventional resonant output structures. Capable of generating 100's of MW/m at frequencies up to K-band, the RK has been proposed as a driver for a future linear collider in one version o...

Moment resisting frames as one of the conventional lateral load resisting systems in buildings suffer from some limitations including code limitations on minimum span-to-depth ratio to ensure the formation of plastic hinges with adequate length at beam ends. According to seismic codes, in ordinary steel moment resisting frames the minimum span-to-depth ratios should be limited to 5 and in speci...
