In order to study the dynamic meshing characteristics of the elliptic cylinder gear and obtain the meshing error of the gear transmission system, the two-dimensional static contact analysis of the gear tooth surface is carried out by using ANSYS software, and the key parts of the contact area of the tooth surface are determined. Then, the dynamic meshing model of the elliptic cylinder gear is e...

Transmission error in gearing system is a critical index for product quality. Gears with appropriate tooth modification can always behave well in transmission error, i.e. the double crowned gears. Nevertheless, to manufacture a gear with double crowning by CNC gear shaving machine indeed costly. This paper investigated the manufacture of double crowned gears by traditional gear shaving machine....

This report proposes a general architecture for error resilient video transmission over mobile wireless networks. Radio link layer, UDP Lite, and error control layer are combined to deal with high error rate in wireless environments. Both sender and receiver algorithms are given. An adaptive algorithm is further presented to automatically adjust parity data length in error control. The performa...

We present and compare several video transmission systems with various feedback and coding strategies for wireless real-time transmission. A channel coding system based on high-memory convolutional codes (CCs) is deployed which aims on delaying the first error within a progressively coded data frame as far as possible. A low-rate feedback channel is introduced to communicate the number of error...

Uncompressed High-Definition video streaming over extremely high frequency using wireless technologies, also known as WirelessHD, is a challenge problem because of the high data rate requirement and channel variations. The advantages in RF technology and the huge bandwidth available in the 57-66 GHZ millimeter wave open new era for High Definition applications and high data rates communication....

We demonstrate the generation of error-free binary-phase-shift-keyed (BPSK) data at 5 Gb/s using a silicon microring modulator. The microring-modulated BPSK signal is propagated at fiber lengths up to 80 km, maintaining error-free performance, while demonstrating resilience to chromatic dispersion. Bit-error-rate measurements and eye diagrams show near equivalent performance of a microring-base...

this study considers the price transmission mechanism between farm and retail levels of beef market in east azerbaijan with weekly prices over 1377:1 to 1390:52 periods. to this end, using advantages of multivariate models, hansen- seo (2002)'s two- regime threshold vector error correction model (tvecm) was estimated by the maximum likelihood approach for evaluate the price transmission me...

less, for any burst of length 11 or less induces at most a burst of length 3 or less and one of length 8 or less in the respective classes of digit positions. Some codes obtained along the same lines are listed in Table II, where (b,, bz) and (n, + n,) mean that the code is a combination of a burst-b, code with code-length n, and a burst-b, code with code-length n 2, each of which is generated ...

In this paper, a method for computing the dynamics of geared system excited by its static transmission error is proposed. The based on iterative spectral (ISM) and harmonic balance (HBM). It shown that dynamic (DTE) can be obtained in frequency domain solving linear equations, which turn allows computation modal physical coordinates system.
