Design and Application of Dance Teaching and Evaluation System Based on Big Data

In order to deeply analyze and evaluate the changes in the comprehensive quality of college students' sports dance, the overall idea of systematically evaluating the changes in the comprehensive quality of college students' sports dance was established. Firstly, this article uses the triangular fuzzy number method to measure the evaluation information of the evaluator's dance curriculum plan according to the evaluation indicators. Then, evaluation information from different groups and analytic hierarchy process (AHP) are used to determine the weight of each evaluation index. Finally, this article constructs a website system based on Python's Django framework. In the final system test and questionnaire survey, it was found that users were relatively satisfied with the accuracy of their evaluations and believed that the accurate performance of in-depth learning data analysis would help them save more time and effort in course selection.

Design and Implementation of Traceability System Based on Blockchain

The fifth Plenary Session of the 19th CPC Central Committee included poverty alleviation and rural revitalization as the main goals of economic and social development during the 14th Five-Year Plan period. Moreover, it has created a new situation of digital sales of poverty alleviation and helps agricultural products such as "agriculture + e-commerce" and "agriculture + live streaming", and the traceability of agricultural products has attracted much attention. Com14bining the current social environment background and the investigation and understanding of the existing agricultural product sales mode of poverty alleviation, we found that the existing sales model chain and the traditional traceability system model have many shortcomings, such as unclear information sources and easy tampering. Based on this design, the idea of constructing a traceability system based on blockchain is proposed, and the required technical and economic feasibility is analyzed to confirm the realization of the idea. It is intended to meet the needs of agricultural product information management, poverty alleviation farmer information management, product traceability, etc. And through the web page and mobile terminal information interaction, the realization of agricultural products at any time, mobile, portable query. The final system test can ensure the normal operation of functions and the security, credibility, and transparency of information, provide new ideas and solutions for the field of targeted poverty alleviation, and help rural revitalization.

Complex validation of novel mullite‐based ceramic filters for microfiltration purposes

AbstractThe goal of this paper is to investigate a complex validation, developed by Rauschert in Poland, of casted ceramic filters for microfiltration. For disc manufacturing, a self‐developed material RaFo‐MF‐401e with a filtration membrane was used. The presented experiment was conducted on component, subsystem, and system levels. Component level analysis consisted of the investigation of mechanical strength, hardness, rough lifetime, and resistance against acids and alkalis. Annealing at high temperature and humidity was used to test the subsystem. The final system test was executed on the real filtration system. The final aim of the tests was to verify the filtration efficiency of a complete module (core and membrane) in a real filtration device. The filtration quality of the whole setup was very good and the particles in the permeate (filtrated solution) were smaller than 10 μm (defined as D99). Thus, the developed discs provide the expected filtration quality in the range of microfiltration.

A Brain-Computer Interface for Teleoperation of a Semiautonomous Mobile Robotic Assistive System Using SLAM

The proposed assistive hybrid brain-computer interface (BCI) semiautonomous mobile robotic arm demonstrates a design that is (1) adaptable by observing environmental changes with sensors and deploying alternate solutions and (2) versatile by receiving commands from the user’s brainwave signals through a noninvasive electroencephalogram cap. Composed of three integrated subsystems, a hybrid BCI controller, an omnidirectional mobile base, and a robotic arm, the proposed robot has commands mapped to the user’s brainwaves related to a set of specific physical or mental tasks. The implementation of sensors and the camera systems enable both the mobile base and the arm to be semiautonomous. The mobile base’s SLAM algorithm has obstacle avoidance capability and path planning to assist the robot maneuver safely. The robot arm calculates and deploys the necessary joint movement to pick up or drop off a desired object selected by the user via a brainwave controlled cursor on a camera feed. Validation, testing, and implementation of the subsystems were conducted using Gazebo. Communication between the BCI controller and the subsystems is tested independently. A loop of prerecorded brainwave data related to each specific task is used to ensure that the mobile base command is executed; the same prerecorded file is used to move the robot arm cursor and initiate a pick-up or drop-off action. A final system test is conducted where the BCI controller input moves the cursor and selects a goal point. Successful virtual demonstrations of the assistive robotic arm show the feasibility of restoring movement capability and autonomy for a disabled user.

Development of an optical pH measurement system based on colorimetric effect

<p>This paper proposed an optical pH measurement system developed to measure the changes of pH levels based on colorimetric reactions with phenol red reagent. The optical sensing was achieved through the implementation of a pair of light emitting diode (LED) and photodiode. The detection mechanism was based on different absorbance of light intensity at pH values of 2.36, 8.32, 9.08 and 12.83. The data processing method was carried out using LabVIEW software and interfaced with NI USB DAQ 6008. The measured voltage showed a good correlation in relation to the pH level with R2 equals to 0.9624. This relationship was used as a calibration curve in the final system testing. The final measurement of pH showed a good agreement between the actual and measured values with an error of less than 5%, thus indicating the reliability of the proposed system.</p>

Results of the KRUSTY Warm Critical Experiments

The Kilowatt Reactor Using Stirling TechnologY (KRUSTY) was a prototypic nuclear-powered test of a 5-kW(thermal) Kilopower space reactor. This paper presents results from the KRUSTY warm critical experiments, which were completed prior to the final system test. The first set of criticals comprised cold or zero-power criticals; i.e., the core was not heated by fission power. These were followed by three warm criticals, where fission power heated the core to 200°C, 300°C, and 450°C, respectively. These criticals provided the data, confidence, and regulatory framework that were needed to proceed with the KRUSTY nuclear system test. The criticals also provided valuable data for the benchmarking of codes applicable to all nuclear systems. Finally, a comparison of KRUSTY results to pretest predictions is provided, and overall, the models matched the experimental results very closely.

Design and realization of bank history data management system based on Hadoop 2.0

With the continuous economic development, the total amount of data in banks is growing bigger and bigger and it is urgent and necessary to manage these data effectively. This paper studied Hadoop-based bank historical data management from the perspective of data migration, and designed and realized a data migration module. Map Reduce data migration was used in the process of structured data migration. An IO load-based scheduling algorithm was also designed. When scheduling, considering the consumption of resources, it is avoided to assign tasks to heavy-loaded IO nodes. An unstructured data migration tool was developed by smartly using FTP to concurrently migrate log files of online service platforms and other data to HDFS specified directories. The final system test results show that the system in this paper can work normally and meet the design requirements.

The Large Binocular Telescope

The Large Binocular Telescope (LBT) Observatory is a collaboration among institutions in Arizona, Germany, Italy, Indiana, Minnesota, Ohio, and Virginia. The telescope on Mount Graham in Southeastern Arizona uses two 8.4 m diameter primary mirrors mounted side by side. A unique feature of the LBT is that the light from the two Gregorian telescope sides can be combined to produce phased-array imaging of an extended field. This cophased imaging along with adaptive optics gives the telescope the diffraction-limited resolution of a 22.65 m aperture and a collecting area equivalent to an 11.8 m circular aperture. This paper describes the design, construction, and commissioning of this unique telescope. We report some sample astronomical results with the prime focus cameras. We comment on some of the technical challenges and solutions. The telescope uses two F/15 adaptive secondaries to correct atmospheric turbulence. The first of these adaptive mirrors has completed final system testing in Firenze, Italy, and is planned to be at the telescope by Spring 2010.

Overview of the SNS target system testing and initial beam operation experience

The Spallation Neutron Source (SNS) construction project has been completed including initial beam operation with the mercury target, moderators and associated systems. The project was initiated in 1999, with groundbreaking in December of 1999. Final integrated system testing for the mercury target, cryogenic moderators, shutter systems, water and other utility systems and all control and safety systems were completed in April 2006 and first beam on target was delivered April 28, 2006. This paper will give an overview of the system testing conducted in preparation for beam operation and initial operating experience with low power beams. One area of testing was extensive remote handling testing in the target service bay to demonstrate all key operations associated with the target and mercury loop. Many improvements were implemented as a result of this experience. Another set of tests involved bringing the supercritical cryogenic moderator systems on line. Again, lessons learned here resulted in system changes. Testing of the four water loops was very time consuming because of the complexity of the systems and many instrumentation issues had to be resolved. A temporary phosphor view-screen was installed on the front of the target which has been extremely useful in evaluating the beam profile on the target. Initial profile results will be presented. Target system performance for initial beam operation will be discussed. In general, all systems performed well with excellent availability. There were some unexpected findings. For example, xenon spallation gas products are believed to have deposited on a downstream gold amalgamation bed designed to remove mercury vapor and this disposition increased the local dose rate. A summary of findings and plans for ramping up in power will be given.

Brazil tests world's largest environmental monitoring system

An elaborate environmental monitoring system paid for by Brazil, Sivam was built by the US defense electronics contractor Raytheon Co. (Lexington, Mass.) and two Brazilian outfits, Embraer (Sao Jose dos Campos) and Atech (Sao Paulo)-the former an aeronautics company that has supplied planes for Sivam, the latter the Brazilian system integrator. The US $1.4 billion system pulls together information from over 500 monitoring devices, ranging from satellites to weather balloons covering 5.2 million km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of the Amazon. System headquarters are going up in Brasilia, the nation's capital, and final system tests on the integration of all the network's components are scheduled to begin in October or November, 2003. Sivam is being used to detect illegal logging in Brazil, but can also be used to monitor fires, floods, pollution, weather, and-not least-the status of land set aside for indigenous peoples. The idea is to feed a constant flow of critically important data to scientists and to public authorities responsible for regulating the development and protection of the rain forest that covers 61 percent of Brazil.

Predictive Toxicology Methods for Transdermal Delivery Systems

Predicting potential toxicologic responses to transdermal delivery is a complex procedure, involving both traditional toxicology protocols for evaluating results of systemic exposure and topical studies assessing skin-drug interactions and reactions. Evaluation of individual drug and system components is followed by final system testing to assess possible interactions. Risk is estimated by analyzing toxicologic data quantitatively, with estimation of human exposure based on dose-response extrapolations. Formulation or system changes designed to minimize risk are evaluated. In some instances local intolerance to a compound—due either to irritation or sensitization—may preclude development of a successful transdermal product despite efficacious plasma levels. For viable projects with acceptable toxicologic profiles, a strategy is implemented to manage risk of irritation and sensitization. In addition to the usual drug-specific systemic toxicology and regulatory issues, a toxicology evaluation plan for trans...

Rapid Prototyping with Fourth Generation Systems: - An Empirical Study

&lt;p&gt;The focus of this paper is on design and evaluation techniques supporting active end-user involvement in Information System (IS) development based on rapid prototyping with Fourth Generation Systems. The paper discusses experiences on the development and use of mainly two sorts of prototypes denoted horisontal and vertical prototypes. The experiences result from an interview study, carried out by the author and two colleagues, in nine Danish development projects.&lt;/p&gt;&lt;p&gt;A central result from the study is that users did not give sufficient response on presented horisontal prototypes. Moreover, unexpected iterations became necessary in most of the projects studied although horisontal prototypes had been accepted by the users. In contrast vertical prototypes, which are capable of handling realistic data from the use domain, appeared to stimulate extensive and constructive response from users before the final system tests. These observations lead to the daim that the developers should be aware of the tacit knowledge which plays an important role in users' work practices. To utilise the users' tacit knowledge, the design techniques based on prototyping should involve the end-users more actively, and the evaluation techniques should support testing in a work-like setting early in the development process.&lt;/p&gt;&lt;p&gt;Three proposals on techniques to meet these requirements are given. The first proposal is aimed at having end-user representatives participating in certain design activities where Fourth Generation Systems are being used. The second proposal is aimed at utilising the potential of simulating functionality behind horisontal prototypes. The final proposal is aimed at performing ongoing evaluation activities in conjunction with design activities.&lt;/p&gt;

Time-Delay Problems Encountered in Integrating the Advanced Simulator for Undergraduate Pilot Training

An advanced Computer Image Generation (CIG) visual system has been integrated with an advanced Flight Training Research Simulator. The integration design was the first developed for integrating a CIG visual system with a sophisticated flight simulator. There was much concern for the unique CIG system transport delay, and techniques were developed which proved to be quite successful in compensating for the majority of this delay. However, not enough concern was given to previously unrecognized and unreported excessive motion system delays which were encountered during final integrated system tests. The integration scheme and the impact of iteration rates, visual and motion system delays, and delay compensation on visual and motion cue coordination as perceived by pilots are presented.

Ground Testing of the SNAP 10A/Agena Space System

The SNAP 10A/Agena Space System, developed under the joint direction of the Air Force Systems Division and the Atomic Energy Commission, is described with emphasis on the inter-relationship of the several subsystems and their integration with the Nuclear Power Unit. Development and refinement of the space system design by means of integrated subsystem and system level testing performed on a full-scale functional mockup of the spacecraft and payload is discussed with emphasis on the instrumentation and telemetry subsystems. The method of demonstrating electromagnetic compatibility of the space system is described, both as performed on the functional mockup and the flight vehicle proper. Final pre-flight system testing of the spacecraft, including the payload and payload simulator, up to the time of launch is discussed. Particular emphasis is placed on the discovery and resolution of problems that appeared only at the system level of testing and those that were the direct result of the uniqueness of the nuclear reactor payload. Integrating a nuclear power unit into a space vehicle and ground testing of the resultant system presented many typical aerospace system problems, but no truly new ones and certainly no insolvable ones. The technology resulting from the development of the SNAP 10A/Agena system is directly applicable to nuclear space systems in general. Subsequent nuclear power systems can be less experimental in nature and require less complex instrumentation and control, with a corresponding reduction in the complexity and time span of ground testing.
