This kind of system has the advantage of energy-saving. But, it also has some defects that have to be improved. Microcomputer control of a pump controlled motor electrohydraulic servo system is studied. A PID controller is first adopted on the closed loop control system, and experimental results are obtained. Then, a model reference adaptive controller is designed and realised on the same system applying a single board microcomputer. Experimental results show that the dynamic properties of the adaptive control system is much better than those of the PID system under different inertia load conditions. 展开更多

Based on the helix rotating screen and the digital micro-mirror device (DMD), the former proto of volumetric-swept display system is improved. The 3-D display system adopting a helix rotating screen to construct an imaging space meliorate the defects, such as the smaller image space, the fewer voxels and the severer voxel overlap dead zone caused by planar rotating screen. DMD with spatial light modular (SLM) technology increases the transmission bandwidth of 3-D data in the voxel activation subsystem and activate multi-voxel once time. The volumetric-swept system based on helix rotating screen and DMD is developed. The experimental results show that the image space, the vision dead zone, the voxels on slice, and the voxel activation capacity of the designed proto are superior to the plane rotating screen system. 展开更多

To model a true three-dimensional(3D)display system,we introduced the method of voxel molding to obtain the stereoscopic imaging space of the system.For the distribution of each voxel,we proposed a four-dimensional(4D)Givone–Roessor(GR)model for state-space representation—that is,we established a local state-space model with the 3D position and one-dimensional time coordi-nates to describe the system.First,we extended the original elementary operation approach to a 4D condition and proposed the implementation steps of the realiza-tion matrix of the 4D GR model.Then,we described the working process of a true 3D display system,analyzed its real-time performance,introduced the fixed-point quantization model to simplify the system matrix,and derived the conditions for the global asymptotic stability of the system after quantization.Finally,we provided an example to prove the true 3D display system’s feasibility by simulation.The GR-model-representation method and its implementation steps proposed in this paper simplified the system’s mathematical expression and facilitated the microcon-troller software implementation.Real-time and stability analyses can be used widely to analyze and design true 3D display systems. 展开更多

In this study, a multipurpose M13KE phage display vector was constructed from wild-type M13KE phage for long peptide or protein display libraries without helper phage to expand the scope of targeted high-throughput screening. Based on the relationship between the structure and function of minor coat protein of wild-type MI3KE (wt-plII), a truncated gene III (tglll) encoding minor coat protein from M13KE phage was cloned. A fusion gene fragment harboring a hw/tac promoter, signal peptide and C-terminal region sequence of gill was assembled with SOEing-PCR (splice-overlapping-extension polymerase chain reaction) method and inserted into M13KE vector. SDS-PAGE and Western blot analysis with anti-M13 pIII moneclonal antibody were employed to detect the expression of re- combinant protein, c-Myc and HA tag sequences were fused into the recombinant protein. The results showed that tglll was inserted into an unessential region of M13KE. According to the results of SDS-PAGE and Western blot with anti-M13 pIII antibody, pIII was expressed by wt-gIII and tgIII, glII harboring two tags ex- pressed both c-Myc and HA peptides using SDS-PAGE and Western blot with the corresponding monoclonal antibodies. In this study, a multipurpose M13KE phage display system was successfully constructed, which could express both short and long peptide libraries without helper phage. In future, the obtained M13KE phage display system may be used for targeted high-throughput screening of long peptide libraries without helper phage. 展开更多

This paper presents the development of numerical prediction products(NPP) correction and display system(NPPCDS) for rapid and effective post-processing and displaying of the T213 NPP(numerical prediction products of the medium range numerical weather prediction spectral model T213L31) through instant correction method. The NPPCDS consists of two modules: an automatic correction module and a graphical display module. The automatic correction module automatically corrects the T213 NPP at regularly scheduled time intervals, while the graphical display module interacts with users to display the T213 NPP and its correction results. The system helps forecasters extract the most relevant information at a quick glance without extensive post-processing. It is simple, easy to use, and computationally efficient, and has been running stably at Huludao Meteorological Bureau in Liaoning Province of China for the past three years. Because of its low computational costs, it is particularly useful for meteorological departments that lack advanced computing capacity and still need to make short-range weather forecasting. 展开更多

The grading judgment for apples is related to a variety of factors including,size,shape,color,texture,and scars.Traditional manual sorting methods are time consuming and labor intensive.In addition,the accuracy of the method is easily subjective,not repeatable,error-prone,and affected by the sorting environment.This paper presents a complete and automated grading system for apples.The system uses a single-chip microcomputer as the controller of the system,and a PC as the graphics processing unit.It also includes a conveyor,drive motor,frequency converter for motor control,photoelectric sensors,air compressor,and air jets for ejecting the graded apples.The classification algorithm is implemented by using a convolutional neural network(CNN).In order to eliminate contact damage of apples,the system specifically uses air jets as actuators to eject the graded apples into the corresponding bins.At the same time,in order to ensure that an apple triggers the correct ejecting actuator,this paper designs a jet controller with proper logic. 展开更多

In this paper, a scalable hardware and software architecture for tiled display systems (a.k.a. videowalls), which can be implemented by using low-cost devices, together with a dynamic web-based management and configuration service are proposed. It has been designed to support both stored and live broadcast/broadband content, in mosaic or warp distributions. The displays and devices can be dynamically configured via web in different ways: the displays can create a single display of a larger size;or they can be configured in a customized way in order to playout different media contents in different display combinations. As display renderers, low-cost devices are proposed as the main hardware element to obtain affordable videowall systems. As a proof of concept, two prototypes have been implemented, including an accurate synchronization mechanism based on a Master/Slave control scheme and aggressive and smooth playout adjustment techniques. To evidence the good performance of the prototypes and configuration service, both objective and subjective evaluations have been conducted regarding synchronization accuracy and usability. On the one hand, the mean values of the asynchronies between the video playout processes in each display are kept below 25ms (i.e., frame accuracy). On the other hand, the obtained usability score in the System Usability Scale (SUS) test has been 88.65, which is considered as excellent. 展开更多

Holography is an interesting tool in creating real objects and scenes which can be projected anywhere with accurate details and depth impression. It is also found to be more attractive to the artists than other alternatives. For that reason, digital holography is being used as a display technology in cartoon movies. Since this application is dependent on the performance and the simplicity of the available display technology, it becomes very useful to improve the display technique in order to become fast, simple, and attractive by being combined with computer graphical effects. This paper discusses a simulation of a digital holographic model as a three dimensional (3D) display system and its application in making cartoon holography. 展开更多

In order to achieve a clear and steady swept-volume display,the method of swept-volume display based on cylindrical space projection was presented. One projector generated the image volume in π× 70 mm × 70 mm × 150 mm space. Experimentally,the resolution of images was 800 pixel × 600 pixel × 360 pixel,which resulted in almost 345 million voxels. In order to achieve space voxels with uniform brightness, curved reflectors were also designed. In addition,the match conditions between triangles and the scanning planes in the volume space were classified and a sweptvolume graphics engine based on embedded platform was designed.The image rendering the hardware foundation for three-dimensional( 3D) dynamic images generation was achieved. Demonstrated in the experiments,light source utilization of the second-generation system based on curved mirror is about three times brighter than the firstgeneration 3D minitor based on flat mirror,and this system is able to display color,clear and well-proportioned 3D images in brighter room light. 展开更多
