Abstract Animation is one of the most fascinating industries in recent years. Nowadays, the most popular three-dimensional animation creation design, three-dimensional animation creation is to rely on CG technology to simulate and realize through the powerful computing power of computers. As designers have higher and higher requirements for animation, the animation creation process has become more complicated, so the skill-based management of the 3D animation creation process will be a problem. This article will study the management of the 3D animation creation system based on computer technology. On the basis of the literature, the relevant theory of the 3D animation creation system is understood, and then the computer technology-based 3D animation creation management system is designed, and the designed system is tested. The test results show that the maximum concurrency of the system in this article The number is 400. After 400, the delay time and packet loss of the system start to rise.

Order Of Magnitude

Obtaining the three-dimensional (3D) structure of negatively stained biological specimens at a resolution of, typically, 2 - 4 nm is becoming a relatively common practice in an increasing number of laboratories. A combination of new conceptual approaches, new software tools, and faster computers have made this situation possible. However, all these 3D reconstruction processes are quite computer intensive, and the middle term future is full of suggestions entailing an even greater need of computing power. Up to now all published 3D reconstructions in this field have been performed on conventional (sequential) computers, but it is a fact that new parallel computer architectures represent the potential of order-of-magnitude increases in computing power and should, therefore, be considered for their possible application in the most computing intensive tasks.We have studied both shared-memory-based computer architectures, like the BBN Butterfly, and local-memory-based architectures, mainly hypercubes implemented on transputers, where we have used the algorithmic mapping method proposed by Zapata el at. In this work we have developed the basic software tools needed to obtain a 3D reconstruction from non-crystalline specimens (“single particles”) using the so-called Random Conical Tilt Series Method. We start from a pair of images presenting the same field, first tilted (by ≃55°) and then untilted. It is then assumed that we can supply the system with the image of the particle we are looking for (ideally, a 2D average from a previous study) and with a matrix describing the geometrical relationships between the tilted and untilted fields (this step is now accomplished by interactively marking a few pairs of corresponding features in the two fields). From here on the 3D reconstruction process may be run automatically.

AbstractFor more than 20 years, precise point positioning (PPP) has been a well-established technique for carrier phase-based navigation. Traditionally, it relies on precise orbit and clock products to achieve accuracies in the order of centimeters. With the modernization of legacy GNSS constellations and the introduction of new systems such as Galileo, a continued reduction in the signal-in-space range error (SISRE) can be observed. Supported by this fact, we analyze the feasibility and performance of PPP with broadcast ephemerides and observations of Galileo and GPS. Two different functional models for compensation of SISREs are assessed: process noise in the ambiguity states and the explicit estimation of a SISRE state for each channel. Tests performed with permanent reference stations show that the position can be estimated in kinematic conditions with an average three-dimensional (3D) root mean square (RMS) error of 29 cm for Galileo and 63 cm for GPS. Dual-constellation solutions can further improve the accuracy to 25 cm. Compared to standard algorithms without SISRE compensation, the proposed PPP approaches offer a 40% performance improvement for Galileo and 70% for GPS when working with broadcast ephemerides. An additional test with observations taken on a boat ride yielded 3D RMS accuracy of 39 cm for Galileo, 41 cm for GPS, and 27 cm for dual-constellation processing compared to a real-time kinematic reference solution. Compared to the use of process noise in the phase ambiguity estimation, the explicit estimation of SISRE states yields a slightly improved robustness and accuracy at the expense of increased algorithmic complexity. Overall, the test results demonstrate that the application of broadcast ephemerides in a PPP model is feasible with modern GNSS constellations and able to reach accuracies in the order of few decimeters when using proper SISRE compensation techniques.

A comprehensive method of estimating the performance of axial flow steam and gas turbines is presented, based on analysis of linear cascade tests on blading, on a number of turbine test results, and on air tests of model casings. The validity of the use of such data is briefly considered. Data are presented to allow performance estimation of actual machines over a wide range of Reynolds number, Mach number, aspect ratio and other relevant variables. The use of the method in connection with three-dimensional methods of flow estimation is considered, and data presented showing encouraging agreement between estimates and available test results. Finally ‘carpets’ are presented showing the trends in efficiencies that are attainable in turbines designed over a wide range of loading, axial velocity/blade speed ratio, Reynolds number and aspect ratio.

Behaviour affects performance and productivity of poultry birds especially chickens, some behavioural traits are advantageous in a particular production system and may be of disadvantage in another production system. The present study compared behavioural of Nigeria Local Chicken, NLC (two separate samples of 11 Yoruba Ecotype) and its Exotic counterparts (11 Broilers and 11 Pullets) by use of the Open Field (OFT), T-Maze, Forced Approach, and Voluntary Approach Tests (FAT and VAT respectively) during two phases of Growth (0-4 Weeks, and 4-8 weeks age respectively). The former group (NLC) is better adapted to extensive management in the Nigerian Guinea savannah than the latter Results showed that Yoruba NLC issued a significantly (p<0.05) higher number of distress calls than the Exotic genotypes in the OFT at age 7 and 48 days, and the NLC issued significantly more calls at 7 days age. Broilers exhibited significantly lower OFT Latency at 7 and 48 days, and Broilers traversed fewer squares and spent less time ambulating than other genotypes at 48 days age. Ina T-maze, Broilers showed significantly (p<0.05) lower exploratory behaviour than other groups (higher latency to leave the start box). In the FAT, NLC showed lower Latency to flight (p<0.05) than the Exotic genotypes. Ethological test results indicate differences in the behavioural characters exhibited by Yoruba NLC and Exotic Chickens and such differences could embody the basis of anecdotal differences in the rates of survival under extensive management conditions, and may be subjected to quantitative genetic selection in the ongoing effort to produce improved chickens that incorporate a combination of desirable traits from both Local and Exotic chickens.

The goal of this study is to develop a racking model of plasterboard-sheathed timber walls as part of the efforts towards performance-based seismic engineering of low-rise light timber-framed (LTF) residential buildings in New Zealand. Residential buildings in New Zealand are primarily stand-alone low-rise LTF buildings, and their bracing elements are commonly plasterboard-sheathed LTF walls. It is an essential part of performance-based seismic designs of LTF buildings to be able to simulate the racking performance of plasterboard walls. In this study, racking test results of 12 plasterboard walls were collected and studied to gain insight into the seismic performance of plasterboard-sheathed LTF walls. The racking performance of these walls was examined in terms of stiffness/strength degradation, displacement capacity, superposition applicability and failure mechanisms. Subsequently, a mathematical analysis model for simulating racking performance of LTF plasterboard walls is developed and presented. The developed racking model is a closed-form wall model and could be easily used for conducting three-dimensional non-linear push-over studies of seismic performance of LTF buildings.
