代码说明:

JSteg隐写算法,基于DCT系数的变换进行数字隐写,matlab代码,已实现,可运行。主要思想是将秘密消息嵌入在量化后的DCT系数的最低比特位上,但对原始值为0、1的DCT系数不进行嵌入。

  • 基于轨迹重规划的智能车辆避障模型预测控制
    为了提高无人驾驶车辆的轨迹跟随性精度和实时性,针对无人驾驶车辆规避障碍物的路径规划问题,本文提出了一种基于轨迹重规划的无人车避障模型预测控制算法。利用车载传感器获得障碍物和参考路径信息,通过轨迹重规划控制器规划出规避障碍物的期望路径, 并将重规划的期望路径信息输入到模型预测控制器,控制输出前轮转角,通过方向盘主动转向实现避障的同时,实现对参考路径的跟踪;最后,利用 CarSim 和 Simulink 建立轨迹重规划和轨迹跟踪的闭环控制系统仿真平台,并以双移线工况为例,进行了仿真验证。结果表明该方法能够在不同车速下实现对障碍物可靠规避的同时,实现对参考路径的稳定跟踪。

The ABAQUSAns wers are solutions to questions that we have had to answer or guidelines on how to use ABAQUS. Wewelcome any suggestions for improvements to the support program or documentation. We will ensure thatany enhancement requests you make are considered for future releases. If you wish to file a complaint aboutthe service or products provided by aBaqUs, refer to the aBaQus Home PageTechnical engineering supportABAQUS technical support engineers can assist in clarifying ABAQUS features and checking errors by givingboth general information on using ABAQUS and information on its application to specific analyses. If youhave concerns about an analysis, we suggest that you contact us at an early stage, since it is usually easier tosolve problems at the beginning of a project rather than trying to correct an analysis at the end.Please have the following information ready before calling the technical engineering support hotline, andinclude it in any written contacts:Your site identifier, which can be obtained by typing abaqus whereami at your system prompt(or byselecting Help-On Version from the main menu bar in ABAQUS/CAE or ABAQUS/Viewer)· The version of△ BAQUS that are you usingThe version numbers for ABaQUS/Standard and ABAQUS/Explicit are given at the top of the data(. dat)fileThe version numbers for ABAQUS/CAE and ABAQUS/Viewer can be found by selectingHelp-On Version from the main menu bar.The version numbers for the abaqus Interface for MoldFLOW and the abaQus Interface forMSC ADAMS are output to the screenThe version number for ABAQUS for CAtIa V5 can be found by selecting Help-AboutABAQUS for CaTiA V5 from the main menu bar in either of the aBaqus for CAtIA V5workbenchesThe type of computer on which you are running ABAQUSThe symptoms of any problems, including the exact error messages, if anyWorkarounds or tests that you have already triedWhen calling for support about a specific problem, any available abaqus output files may be helpful inanswering questions that the support engineer may ask youThe support engineer will try to diagnose your problem from the model description and a description ofthe difficulties you are having. The support engineer may need model sketches, which can be sent via fae-mail, or regular mail. Plots of the final results or the results near the point that the analysis terminated mayalso be needed to understand what may have caused the problemIf the support engineer cannot diagnose your problem from this information, you may be asked tosupply the input data. The data can be attached to a support incident in the aBaQUS Online SupportSystem. It may also be sent by means of e-mail, tape, disk, or ftp Please check the ABAQUS Home Page(http://www.abaquscom)forthemediaformatsthatarecurrentlyacceptedAll support incidents are tracked in the abaQUs Online Support System. This enables you( as well asthe support engineer) to monitor the progress of a particular problem and to check that we are resolving supportissues efficiently. To use the ABAQUS Online Support System, you need to register with the system. Visit theMY ABAQUS Section of the ABAQUS Home Page for instructions on how to register. If you are contactingus by means outside the aoss to discuss an existing support problem and you know the incident number,please mention it so that we can consult the database to see what the latest action has been and, thus, giveyou more efficient support as well as avoid duplication of effort. In addition, please give the receptionist thesupport engineers name if contacting us via telephone or include it at the top of any e-mail correspondenceSystems supportABAQUS SyStems support engineers can help you resolve issues related to the installation and running ofABAQUS, including licensing difficulties, that are not covered by technical engineering supportYou should install ABaQUS by carefully following the instructions in the ABAQUS Installation andLicensing Guide If you are able to complete the installation, please make sure that the product verificationprocedure was run successfully at the end of the installation procedure. Successful verification for licensedproducts would indicate that you can run these products on your computer; unsuccessful verification forlicensed products indicates problems with the installation or licensing (or both ) If you encounter problemswith the installation, licensing, or verification, first review the instructions in the abaQus Installation andLicensing Guide to ensure that they have been followed correctly. If this does not resolve the problems,consult the ABAQUS Answers database in the ABaQUS Online Support System for information about knowninstallation problems. If this does not address your situation, please create an incident in the AOSS anddescribe your problem, including the output from abaqus info=support. If you call, mail, e-mail, or faxus about a problem(instead of using the Aoss), please provide the output from abaqus info=support. Itis important that you provide as much information as possible about your problem: error messages from anaborted analysis, output from the abaqus info=support command, etc
