MSC.1-Circ.1353 - Revised Guidelines For The Preparation Of The Cargo Securing Manual (Secretariat)

MSC.1-Circ.1353 - Revised Guidelines For The Preparation Of The Cargo Securing Manual (Secretariat)

PREAMBLE 1 In accordance with the International Convention for the Safety of Life at Sea, 1974 (SOLAS) chapters VI, VII and the Code of Safe Practice for Cargo Stowage and Securing (CSS Code), cargo units, including containers shall be stowed and secured throughout the voyage in accordance with a Cargo Securing Manual, approved by the Administration. 2 The Cargo Securing Manual is required on all types of ships engaged in the carriage of all cargoes other than solid and liquid bulk cargoes. 3 The purpose of these guidelines is to ensure that Cargo Securing Manuals cover all relevant aspects of cargo stowage and securing and to provide a uniform approach to the preparation of Cargo Securing Manuals, their layout and content. Administrations may continue accepting Cargo Securing Manuals drafted in accordance with Containers and cargoes (BC) – Cargo Securing Manual (MSC/Circ.385) provided that they satisfy the requirements of these guidelines. 4 If necessary, those manuals should be revised explicitly when the ship is intended to carry containers in a standardized system. 5 It is important that securing devices meet acceptable functional and strength criteria applicable to the ship and its cargo. It is also important that the officers on board are aware of the magnitude and direction of the forces involved and the correct application and limitations of the cargo securing devices. The crew and other persons employed for the securing of cargoes should be instructed in the correct application and use of the cargo securing devices on board the ship.

2022考研英语阅读德国汽车生产商German carmakers德国汽车生产商Stuck in third稳居第三Daimler is set to keep chugging down the Autobahnbehind BMW and Audi奔驰意欲一举赶超宝马奥迪AS A corporate motto, The best or nothing has a timeless quality.作为戴姆勒公司的座右铭,唯有最好彰显着一种永恒的品质。

Gottlieb Daimler pasted it on the wall as he went about inventing the modern car in the late19th century.十九世纪晚期,当戈特利布戴姆勒着手创造现代汽车的时候,他将这句话贴在墙上。

In 20xx the firm that bears his name adopted it as a slogan.20xx年,这个以其创始人名字命名的公司将这句话作为广告语。

It was as badly timed as a misfiringengine. Mercedes-Benz, Daimler s car division, already trailing BMW in terms of sales andprofitability, saw another Geman premium carmaker, Audi,also start to pull away in thesame year.作为一个正走下坡路的公司,这个口号来的有点晚。

在销量、盈利方面,戴姆勒旗下的奔驰都已双双落后宝马。

同期,德国另一高档汽车制造商奥迪也开头将奔驰甩在身后。

Yet this year Daimler s shares have surged by 40%, persuading optimists that the firm iscatching up.然而,今年戴姆勒公司的股价涨幅高达40%,乐观人士开头认为正确而不怀疑该公司正逐步赶上。

documents•Prerequisite documents•Documents which provide background and/or context for thisdocument•Documents that result from this document (e.g. a test plan or adevelopment plan)–Define any important terms, acronyms, or abbreviations–Summarize (or give an abstract for) the contents of this document.Design document template (3)•System Overview–Provide a general description of the software system:•functionality and•matters related to the overall system and its design•[discussion of the basic design approach or organization] •Design Considerations–describes many of the issues which need to be addressed or resolved before attempting to devise a complete design solution •Assumptions and Dependencies–Describe any assumptions or dependencies regarding the software and its use:•Related software or hardware•Operating systems•End-user characteristics•Possible and/or probable changes in functionalityDesign document template (4)•General Constraints–global limitations or constraints that have a significant impact on the design:•Hardware or software environment•End-user environment•Availability or volatility of resources•Standards compliance•Interoperability requirements•Interface/protocol requirements•Data repository and distribution requirements•Security requirements (or other such regulations)•Memory and other capacity limitations•Performance requirements•Network communications•Verification and validation requirements (testing)•Other means of addressing quality goals•Other requirements described in the requirements specificationDesign document template (5)•Goals and Guidelines–goals, guidelines, principles, or priorities which dominate or embody the design of the system's software:•The KISS principle ("Keep it simple stupid!")•Emphasis on speed versus memory use•working, looking, or "feeling" like an existing product –for each such goal or guideline, unless it is implicitly obvious, describe the reason for its desirability•Development Methods–describe the method or approach used for this software design –include a reference to a more detailed description of formal or published methodsDesign document template (6)•Architectural Strategies–decisions and/or strategies that affect the overall organization of the system and its higher-level structures–should provide insight into the key abstractions and mechanisms used in the system architecture–the reasoning employed for each decision and/or strategy and how any design goals or priorities were balanced or traded-off•Use of a particular type of product (programming language, database, library, etc. ...)•Reuse of existing software components to implement various parts/features of the system•Future plans for extending or enhancing the software•User interface paradigms (or system input and output models)•Hardware and/or software interface paradigms•Error detection and recovery•Memory management policies•External databases and/or data storage management and persistence•Distributed data or control over a network•Generalized approaches to control•Concurrency and synchronization•Communication mechanisms•Management of other resourcesDesign document template (7)•System Architecture–high-level overview of how the functionality and responsibilities of the system were partitioned and then assigned to subsystems or components –not too much detail about the individual components themselves–main purpose: to gain a general understanding of how and why the system was decomposed, and how the individual parts work together to provide the desiredfunctionality–major responsibilities that the software must undertake and the various roles that the system (or portions of the system) must play–how the system was broken down into its components/subsystems–how the higher-level components collaborate with each other–provide some sort of rationale for choosing this particular decomposition–make use of design patterns–include any diagrams, models, flowcharts, documented scenarios or use-cases of the system behavior and/or structure•Subsystem Architecture–more detailed discussion of particular components–how the component was further divided into subcomponents, and the relationships and interactions between the subcomponents–recurse if necessary, but leave the details for the Detailed System Design sectionDesign document template (8)•Policies and Tactics–Choice of which specific product to use (compiler, interpreter, database, library, etc. ...)–Engineering trade-offs–Coding guidelines and conventions–The protocol of one or more subsystems, modules, or subroutines–The choice of a particular algorithm or programming idiom (design pattern) to implement portions of the system's functionality –Plans for ensuring requirements traceability–Plans for testing the software–Plans for maintaining the software–Interfaces for end-users, software, hardware, and communications–Hierarchical organization of the source code into its physical components (files and directories).–How to build and/or generate the system's deliverables (how to compile, link, load, etc. ...)Design document template (9)•Detailed System Design–detailed description of the components introduced in “System Architecture”chapter–Classification•kind of component, such as a subsystem, module, class, package, function, file, etc. ....–Definition•specific purpose and semantic meaning of the component.–Responsibilities•primary responsibilities and/or behavior of this component:–What does this component accomplish?

奇思妙想 折叠汽车 作文

奇思妙想折叠汽车作文英文回答:Folding cars? That sounds like something out of a sci-fi movie! But hey, I'm all for innovation and thinking outside the box, so let's explore this idea.Imagine a car that can fold itself up into a compact size, making it easier to park and store. It could be a game-changer for urban dwellers like me who struggle to find parking spaces. Just think about it no more circling the block for hours, no more parallel parking nightmares. With a folding car, I could simply pull up to my destination, press a button, and watch as my car neatly folds itself into a small package.But how would it work? Well, I envision a car with flexible materials and joints that allow it to fold and unfold. Think of it like origami, where the car's body panels and roof can fold inward or outward, reducing itsoverall size. Of course, safety would be a top priority, so the car would need to have sturdy construction and secure locking mechanisms to ensure it stays in place when folded.Now, let's talk about the benefits of a folding car. Aside from the obvious convenience of parking, it could also have a positive impact on the environment. With smaller cars taking up less space on the road, traffic congestion could be reduced, resulting in fewer emissions and a cleaner atmosphere. Plus, imagine the possibilities for car-sharing services or rental companies. They couldfit more cars in their fleets, making transportation more accessible and affordable for everyone.But like any new technology, there would be challenges to overcome. Safety regulations and crash testing would need to be adapted to account for the unique design of a folding car. And what about maintenance? Would it be more complicated or expensive to repair a car with moving parts? These are all factors that would need to be carefully considered and addressed.中文回答:折叠汽车?听起来就像是科幻电影中的东西!但是嘿,我支持创新和超越常规的思维,所以让我们来探索这个想法。

1. 文档介绍
1.1 文档目的
本文档是为了描述利用FPGA来模拟信号控制灯的系统而设计的,在文档中对多种不同的设计进行简要的描述和权衡比较。

利用分解视图,实现视图,执行视图和任务视图来从系统的各个方面进行描述,得出通俗易懂的设计方案。

1.2 文档范围
本文档是为了设计信号控制系统而设计的,按照RUP的《软件架构文档模板》编写,用来指导系统的设计。

1.3 参考文献
[可编程逻辑系统VHDL设计技术] Kevin Skahill[美],东南大学出版社,1998:59-60
[汽车信号灯控制系统的设计] 郝宁生
[汽车车灯控制系统的VHDL语言实现] 郑应民
2. 系统概述
本系统是一个信号灯的控制系统,它是在FPGA实验平台上实现的,主要用来熟悉汽车信号灯的控制方式,并且可以在实验平台上加入一些自己认为有价值的模块。

系统的主要功能描述如下:
(1) 左/右转弯(合上左/右转弯开关):左/右转弯灯闪烁,对应的仪表灯亮
(2) 紧急开关合上:所有灯闪烁。

(3) 刹车(合上刹车开关):左右尾灯亮。

(4) 左/右转弯刹车:左/右转弯灯闪烁(频率高),左右尾灯亮。

(5) 刹车、合上紧急开关:尾灯亮、其它灯闪烁。

(6) 停靠(合上停靠开关):头灯、尾灯闪烁。

(7) 夜间(合上示宽开关):左/右示宽灯亮。

(8)复位开关:所有灯灭(初始状态)。

3. 设计约束
本设计在FPGA实验平台上实现,因此所设计的模块必须与实验平台相对应。

设计所用的程序用Verilog HDL语言来编写。

初步准备将程序得用QUARTUS II软件来综合,利用Modelsim软件来进行仿真。

4. 设计策略
我们的设计工作主要分为两个阶段,首先是系统仿真功能的实现,这也是一个基本阶段,就是实现在实验板上对相应的信号灯进行控制。

其次是优化阶段,因为目前的信号灯控制系统都是基于人工操作的,但是在一些情况下难免会发生意外,例如,我们有些时候会忘记相应的操作,这样难免会给其它的驾驶员发出错误的信号,造成不好的结果。

因此在优化阶段我们会考虑是否可以用系统代替人来完成转向灯控制的操作。

如果得到了这样一种方法,我们就可以在第一阶段的基础上来进行测试。

因为它只是代替了人工操作这一环节,因此可以直接利用第一阶段完成程序来测试结果。

5. 系统总体结构
系统主要包含三个子模块,主要的是控制模块,也就是用来处理接收到的操作信息,然后再将控制数据传输出去。

接下来是操作模块,它用来输入操作员想要实现的功能。

显示模块是对操作的反馈,说明系统是否成功实现。

这三个模块全部在FPGA开发板上,利用开发板的电路来完成系统。

在对系统上电以后首先进行的是复位的工作,复位后的系统直接进入查询模式,就是查询对应的输入有没有变化,也就是查询键盘有没有出现高电平或者上升沿,如果没有出现的话那么就进行一个空操作,继续查询输入的设备有没有操作。

控制模块
操作模块显示模块
系统分解视图
当按下一个按键时,也就是对系统作出了一个操作,那么由系统扫描8个键盘的输入信号电平,然后传送到控制芯片中,在控制芯片中对相应的输入状态进行比较,比较的对象是已经存储在芯片中的状态(因为本电路就涉及8个状态,因此可以利用比较的方法来设计)。

将比较的结果转化为相应的输出来驱动LED 二极管来显示结果。

实现视图如下所示:
系统的实现视图
例如操作员只按下了按键3,那么就会向系统提出一个中断请求,由系统响应中断并扫描键盘阵,因为只按下了一个键,则扫描得到的结果就是00001000(设高电平为1,低电平为0,如果按键按下,则对应的位就为高)。

系统将扫描的结果合成一个数组,与存储的状态(也是8位的数组)进行比较,然后选择正确的状态后将结果传送给输出(显示模块)。

下图所示是系统的执行视图:







系统执行视图
6. 开发环境的配置
系统在FPGA实验平台上开发,要用到的主要实验板就是ML505 Evaluation Platform,如下图所示,程序仿真和综合我们利用QUARTUS II和Modelsim相结合来完成,因为Modelsim有很强大的仿真功能,在仿真这一环节能够很好的测试程序,但它不具备综合功能。

因此将它们综合起来使用,互相补充,可以达到很好的效果。

ML505FPGA开发平台。
