In this paper, we address a blind frame synchronization problem where the receiver acts as an eavesdropper in wiretap channel. A challenging condition is considered, has completely no prior information except that unknown word (SW) repeated nonperiodic fashion. Although autocorrelation method was proposed for fixed length scenario, scheme not applicable to variable-length scenario. To solve pro...

We propose a deep learning approach for wave propagation in media with multiscale speed, using second-order linear equation model. use neural networks to enhance the accuracy of given inaccurate coarse solver, which under-resolves class and fields interest. Our involves generating training data by computationally efficient solver another sufficiently accurate applied (described their speed prof...

OBJECTIVE To introduce a newly designed massage instrument, the Hand Grip T-bar (HT-bar) and use it to relieve chronic non-specific low back pain (nLBP) through deep cross-friction massage (roptrotherapy). METHOD 22 subjects (9 males and 13 females, aged 51.6±6.7) with chronic nLBP were allocated randomly to a Roptrotherapy group (n=12) and a Transcutaneous Electrical Nerve Stimulation (TENS)...

The deep-drawability of a sheet metal blank is strongly influenced by the tribological conditions prevailing in deep-drawing process. Therefore, new methods to influence tribology represent an important research topic. In this work, application process-integrated lubrication process investigated. Most promising geometries channels and outlet openings are first identified means numerical simulat...

This paper arises from our concern for the level of teaching of engineering drawing at tertiary institutions in Australia. Little attention is paid to teaching hand drawing and tolerancing. Teaching of engineering drawing is usually limited to Computer-Aided Design (CAD) using AutoCAD or one of the solid modelling packages. As a result, many engineering graduates have difficulties in understand...

Drawbeads are applied in the deep drawing process to improve the control of the material flow during the forming operation. These drawbeads can be replaced by an equivalent drawbead in simulations of the deep drawing process. In this paper the implementation of an equivalent drawbead model in a finite element code is described. This equivalent drawbead takes not only the drawbead restraining fo...

We present DeepWiVe , the first-ever end-to-end joint source-channel coding (JSCC) video transmission scheme that leverages power of deep neural networks (DNNs) to directly map signals channel symbols, combining compression, coding, and modulation steps into a single transform. Our DNN decoder ...

UNLABELLED The relationship between orthodontic force and friction produced from an archwire and brackets affects the sliding of the wire in the leveling stage. OBJECTIVE The purpose of this study was to evaluate the relationship between force and friction in a small esthetic nickel-titanium (Ni-Ti) wire. MATERIAL AND METHODS Five esthetic wires (three coated and two plated) and two small, ...

The objective of the article is to evaluate the impact of the friction force mouse-pad in the contraction level of the forearm muscles M. extensor carpi ulnaris, M. extensor digitorum and M. extensor carpi radialis longus. A standard protocol of mouse movements was performed involving horizontal, vertical and diagonal mouse displacements drag-anddrop type. The operators were instructed to execu...

Low qualified rate and inferior quality frequently occurring in the general deep drawing process of a certain box-shaped part, now use hydroforming to optimize forming process, in order to study the effect of hydroforming for improving the quality and formability, purposed five process schemes: general deep drawing, active hydroforming, passive hydroforming, general deep drawing combined with a...
