investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

SENSITIVITY EVALUATION OF THE FULCRUM IN THE 10 N·m DEAD WEIGHT TORQUE STANDARD MACHINE AND PERFORMANCE EXAMINATION OF A 1 N·m TORQUE MEASURING DEVICE

− Many torque tools, such as torque wrenches and torque screwdrivers, as well as torque measuring devices (TMDs) of rated capacity of less than 5 N·m are being used. Thus, a small-rated-capacity torque standard has to be established as soon as possible. To this end, design and development of a dead-weight torque standard machine with a rated capacity of 10 N·m (10 N·m-DWTSM) started in 2006 at ...

Design of a 1-V 90-nm CMOS adaptive LNA for multi-standard wireless receivers

This paper presents the design of a reconfigurable Low-Noise Amplifier (LNA) for the next generation of wireless hand-held devices. The circuit, based on a lumped-approach design and implemented in a 90nm standard RF CMOS technology, consists of a two-stage topology that combines inductive-source degeneration with MOS-varactor based tuning networks and programmable bias currents, in order to ad...

Design, Construction and Performance Evaluation of the Walnut Cracking Machine

The traditional method in Iran of cracking walnut manually, using harmer or knife cutter is laborintensive, slow and tedious; besides, most mechanical crackers do not give satisfactory results in terms of kernel extraction quality. A prototype machine was developed to crack walnut. A walnut cracker was designed, constructed and tested to evaluate its performance. The cracker, which consists of ...
