this study was carried out to investigate the effect of selection on the reduction of fat-tail size in lori-bakhtiari lambs. the study lasted for five years at the development and breeding center of lori-bakhtiari sheep station. estimation of fat-tail weight, using external fat-tail dimensions was obtained from regression procedure at 6 month age. soft tissue depth at the point 12 cm from the m...

Soft robots can exhibit diverse behaviors with simple types of actuation by partially outsourcing control to the morphological and material properties of their soft bodies, which is made possible by the tight coupling between control, body, and environment. In this paper, we present a method that will quantitatively characterize these diverse spatiotemporal dynamics of a soft body based on the ...

The basic concepts for exoskeletal systems have been suggested for some time with 21 applications ranging from construction, manufacturing and mining to rescue and emergency services. In recent years, research has been driven by possible uses in medi23 cal/rehabilitation and military applications. Yet there are still significant barriers to the effective use and exploitation of this technology....

We describe a compression scheme for the geometry component of 3D animation sequences. This scheme is based on the principle component analysis (PCA) method, which represents the animation sequence using a small number of basis functions. Second-order linear prediction coding (LPC) is applied to the PCA coefficients in order to further reduce the code size by exploiting the temporal coherence p...

Autonomous Robots have achieved considerable results in a wide variety of domains, from the depths of the ocean to the surface of Mars, and yet many vital locations, particularly collapsed buildings and mines, remain largely inaccessible. In light of recent natural disasters in Haiti and Chile, there is a compelling need for more versatile and robust search and rescue robots. Imagine, for insta...

Soft machines have recently gained prominence due to their inherent softness and the resulting safety and resilience in applications. However, these machines also have disadvantages, as they respond with complex body dynamics when stimulated. These dynamics exhibit a variety of properties, including nonlinearity, memory, and potentially infinitely many degrees of freedom, which are often diffic...

Soft-body models represent elastic deformable objects in a virtual environment, which makes them particularly appropriate for a simulation of objects made of organic materials. Simulation environments created for medical purposes are the most usual applications that employ soft bodies. We present a model of muscles for one of such environments. The model is based on the mass-spring systems, whi...

Motivated by existing models used for soft body simulation which are rather complex to implement, we present a novel technique which is based on simple laws of physics and gives high quality results in real-time. We base the implementation on simple thermodynamics laws and use the Clausius-Clapeyron state equation for pressure calculation. In addition, this provides us with a pressure force tha...

A number of armed assaults on public officials occurred in the early 1970s, which prompted the Lightweight Soft Body Armor Program to develop modern, concealable, soft body armor. Methodology needed to be developed to (1) determine the effectiveness of the soft body armor to stop bullet penetration and (2) assess the potential injury from nonpenetrating blunt impacts to the body. Extensive rese...
