This paper develops the concept of a contour of complete nonuniqueness and shows its application to the optimal design (optimal layout) of simple trusses transmitting a concentrated force to a presscribed, arbitrary foundation contour. As an example, a symmetric two-bar truss with compressed bars is considered, and the constraints refer to various kinds of elastic instability of the system.

Telemedicine is the way to provide better health care facilities to the people of the underprivileged unprocurable areas. As constraints on time and resources makes face to face consultation increasingly dearly-won, and telemedicine has the potential to produce major efficiencies in the symptomatic process. Therefore the goal of current research is to truss medicine with technology, and to prod...

Rigidizable-Inflatable (RI) materials offer the possibility of deployable large space structures (C.H.M. Jenkins (ed.), Gossamer Spacecraft: Membrane and Inflatable Structures Technology for Space Applications, Progress in Aeronautics and Astronautics, 191, AIAA Pubs., 2001) and so are of interest in applications where large optical or RF apertures are needed. In particular, in recent years the...

The economy of the steel truss girder bridge superstructure, used extensively in medium and long span ranges, is affected by many factors such as the cost of material, dictated by the configuration and depth of truss, shape and size of members, and cost of fabrication. Most conventional methods of optimization deal with only member optimization assuming only continuous design variables, leading...

1. Abstract In this paper we present what we call a Neuro-Mechanical Shape Memory Device (NMSMD), together with a method for configuration of such devices. This work builds on previous efforts dealing with the concept of Neuro-Mechanical Networks, and a NMSMD is here defined as a Neuro-Mechanical Network (NMN) which has the ability to take on certain predefined shapes when subject to external (...

The process of forming new architectural solutions in the field regular frame-rod systems necessitates development concept creating original spatial structures through directed transformation kinematically changeable truss-type objects. article presents a numerical study kinematic parameters during gradual shaping rod system, which its initial state is flat hinge-rod network repeating fragments...

The increasing use of advanced sensing technologies for strain measurements necessitates the development of strain-based identification methodologies. In this study, a three-step neural network strategy, called direct soft parametric identification (DSPI), is presented to identify the member stiffness and damping parameters of a truss structure directly from free vibration-induced strains. The ...

Competitive leadership in the international marketplace, superiority in national defense, excellence in productivity, and safety of both private and public systems are all national defense goals which are dependent on superior engineering design. In recent years, it has become more evident that early design decisions are critical, and when only based Qn performance often result in products whic...

vehicular ad-hoc network (vanet) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board computing and communication devices which enable vehicle-to-vehicle communication. consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity would be a challenging problem. clustering technique as ...
