This work is focused on the evaluation of the dynamic performance of different neck protection devices. In order to evaluate the mechanical response of the safety devices, a multibody model of the human neck has been developed in Matlab™ SimMechanics™. The mechanical behavior of the neck is described in the paper and different injury indices are presented and compared. The information about anatomy and physiology of the cervical spine of the neck has been collected from the literature, with particular focus on the mechanism of damage of vertebrae, disks and soft tissues. The multibody model has been validated against experimental data available in the literature concerning impulsive loads representative of crash phenomena. By means of the presented model, some relevant injury indices are computed for an accident involving a motorcyclist. Since the focus has been set on mild injuries of the neck, the simulated crash should cause a high probability of injuries of the neck together with a low probability of damages of the head while wearing a standard helmet. The performance of neck safety devices that link the helmet with the thoracic-shield are evaluated and compared. For sake of clearness, three types of neck safety devices are considered referencing to US patents: an airbag jacket, a 3D cushion wrapping the motorcyclist’s neck, and a “spring and dampers” system. The airbag jacket has been modeled as a high stiffness and low deformation system by considering the airbag in its fully deployed configuration and by neglecting its dynamic performance during inflation phase. The other safety devices have been modeled as lumped parameters spring-damper systems. A sensitivity analysis on the injury indexes has been performed by changing the stiffness and the damping parameters of these safety systems. The injury indexes collected by simulating the different neck safety systems have been compared.

Clothing has a symbiotic relationship with the body, clothing should be designed to meet the needs of different size, which means that virtual design to construct a three-dimensional garment style and the ability to adjust its key parts. Realistic three-dimensional garment tectonic deformation and showcase not only in computer graphics and virtual reality of a frontier research areas and hot spots for apparel and virtual exhibition industry deformation efficiency, research a suitable costume deformation system. Firstly, starting from the basics of clothing, a 3D garment model, a system design, describes the virtual garment construction method, summarized the main algorithms suitable clothing deformation, which can effectively be parameterized specific clothing deformation show.

The shape optimization of a supersonic aircraft need a composite model combining a 3D CFD high-fidelity model and a simplified boom propagation model. The management of this complexity is studied in an optimization loop, with exact discrete adjoints of 3D flow and mesh deformation system. The introduction of a mesh adaptation algorithm is also considered.

Intending to identify that how meaning in the source text has been reproduced in the translated text, the study attempts to investigate deforming tendencies used in the selected poems of Abdul Ghani Khan translated from Pashto into English by Imtiaz Ahmed Sahibzada. Imtiaz Sahibzada has translated 141 poems from the mammoth corpus of Abdul Ghani Khan's Poetry into English and named it The Pilgrim of a Beauty. Using judgmental sampling, ten poems were selected and were analysed in the light of Antoine Berman's (1965) Text Deformation System which includes twelve deforming tendencies. While analysing the translated text in comparison with the source text, deformation in terms of semantics and the syntactic structure was found. Abdul Ghani Khan's poetry translation is considerably deformed, and the translator has little maintained the composition, musicality, and structure of the source text because of different reasons. He has deformed the beauty of the source text poems at the cost of the message due to the use of various deforming tendencies.

The generation of submicrometer-sized particles during dry sliding between stainless steel surfaces is investigated by means of a laser spectrometer for particle counting and scanning tunnelling microscopy for asperity topography characterization. It has been found that, when the submicrometer wear increases with increasing sliding distance or with an initially rougher surface, the number of particles having a submicrometer size is a power function of that size. The two wear coefficients in the power function are determined empirically for the case of stainless steel contact. Different from the generation pattern of several-micrometer particles, the generation rate of submicrometer particles continuously increases until reaching the equilibrium surface condition. The asperity topography measurement shows the micrometer-sized asperities also have subasperities whose sizes are about one order of magnitude smaller. An asperity model similar to Archard’s is thus proposed for estimation of submicrometer wear. The dominant wear mechanisms are brittle fracture and plastic deformation combined with adhesion transfer. The asperity contact can be considered as a plastic-elastic deformation system with subasperities deformed plastically all the time and the micrometer asperities first deformed plastically and then deformed elastically because of the significant increase of microhardness on the soft surface in a metal pair. When the microhardness ratio between two rubbing surfaces reaches a stable value, the generation of submicrometer particles reaches the maximum rate and the wear grows steadily.
