such as the industrial locale, vehicle navigation and sonar it has been used in level measurement, selfguided autonomous vehicles, fieldwork robots automotive navigation, air and underwater target detection, identification ,location and so there is an important practicing meaning to learn the ranging theory and ways improve the precision of the ultrasonic ranging system in hand, satisfy the request of the engineering personal for the precision,the bound and the usage, a portable ultrasonic ranging system based on the single chip processor was : Ultrasound r, Ranging System, Single Chip Processor With the development of science and technology, the improvement of people’s standard of living, speeding up the development and construction of the drainage system have greatly developed their situation is constantly , due to historical reasons many unpredictable factors in the synthesis of her time, the city drainage particular drainage system often lags behind urban , there are often good building excavation has been building facilities to upgrade the drainage system brought to the city sewage, and it is clear to the city sewage and drainage culvert in the sewage treatment is very important to people’s robots designed to clear the drainage culvert and the automatic control system Free sewage culvert clear guarantee robot, the robot is designed to clear the culvert sewage to the System is the core ponent of the development of ultrasonic range , it is very important to design a good ultrasonic range subject backgroundWith the development of economy and car scientific and technological progress, highway traffic presents driving fast pace, traffic dense is changed and the driver not professional the same time, along with the rapid development of auto industry, automobile yield and quantities are increased road development,中原工學(xué)院畢業(yè)設(shè)計(jì)(論文)譯文transportation management is relatively backward, leading to a large number of traffic accidents in some cities, especially transportation system in the world, ITS transportation science and technology of advanced technology, ITS exerting existing infrastructure of potential, enhance the transport efficiency, safeguard traffic safety and ease traffic wager plug, improving urban environment aspects of outstanding performance, has received the governments of widespread Chinese government is also highly intelligent transportation system of the development and popularization automotive anticollision system as ITS development of a base, ITS success to the whole system has a very significant , auto safety said can be divided into two main research direction: first,it is active safety technology, including the prevention of accidents, the way is now automotive safety

課題設(shè)計(jì)的意義隨著現(xiàn)代社會(huì)工業(yè)化程的發(fā)展,汽車(chē)這一交通工具正為越來(lái)越多的人所用,但是隨之而來(lái)的問(wèn)題也顯而易見(jiàn),那就是隨著車(chē)輛的增多,交通事故的頻繁發(fā)生,由此導(dǎo)致的人員傷亡和財(cái)產(chǎn)損失數(shù)目驚人。城市污水給人們帶來(lái)的困擾,因此箱的排污疏通對(duì)大城市給排水系統(tǒng)污水理,人們生活舒適顯得非常重要。在此類(lèi)別中的所有規(guī)則都列在附錄A。語(yǔ)義網(wǎng)絡(luò)被定義為當(dāng)前Wed的延伸,這些網(wǎng)站的信息都給出明確的含義。除了本體作為概念化的形式主義的重要性,它有可能超過(guò)所代表的數(shù)據(jù)。第4部分說(shuō)明了現(xiàn)在正在進(jìn)一步研究的事實(shí),并介紹了我們的新思想。研究交通的目的是為了優(yōu)化運(yùn)輸,人流以及貨流。TC=(DHC+IHC)/TTC:?jiǎn)T工流失成本DHC:直接招聘費(fèi)用(廣告費(fèi)、攤位費(fèi)、招聘人員費(fèi)用等)T:離職職位總數(shù)我們統(tǒng)計(jì)出了以上需要的數(shù)據(jù),但是員工離職這個(gè)問(wèn)題在公司里面還不是很清楚,即使通過(guò)離職面談,也可能得不到最真實(shí)的反饋,他們回答中最常見(jiàn)離職原因是想得到更高的薪酬或者是想找到一份更加好的工作。但在剩余的時(shí)間里面因項(xiàng)目經(jīng)理個(gè)人離職而把項(xiàng)目擱置下來(lái)了,在項(xiàng)目經(jīng)理離開(kāi)后,項(xiàng)目人員會(huì)問(wèn)以下的問(wèn)題。然而,更大的挑戰(zhàn)是設(shè)法去留住那些員工。有一種辦法不僅能夠降低公司的離職人數(shù),并且能夠?yàn)閱T工離職做好準(zhǔn)備。你公司是如何維持的?聽(tīng)取員工的意見(jiàn)尊重員工鼓勵(lì)工作出色的員工要求員工投入信任員工公平公正堅(jiān)定但不殘暴勇于承認(rèn)錯(cuò)誤愉快的工作環(huán)境優(yōu)質(zhì)的住宿環(huán)境雖然對(duì)員工離職暫時(shí)還沒(méi)有一個(gè)根本的解決方法,但是還是有很多有效的措施來(lái)降低員工的離職率,我們不能忘記那些為我們工作的員工特別是從開(kāi)始到結(jié)束為公司工作的員工,我們依靠他們的知識(shí)、技能,而且他們當(dāng)中的大多數(shù)人承諾及時(shí)地完成高質(zhì)量的工作。在研究中,我們著重于微觀(guān)模型,該模型能模仿單獨(dú)車(chē)輛的行為,從而模仿動(dòng)態(tài)的車(chē)輛組。通過(guò)這種方式,增加軟件的獨(dú)立性和為其他的軟件開(kāi)發(fā)活動(dòng)如測(cè)試和維護(hù),提供了便利。本文的目的是介紹一個(gè)紅綠燈有效控制孤立交叉口這方面的知識(shí)重用的控制本體。另一種模糊的規(guī)則類(lèi)別涉及估計(jì)優(yōu)化周期時(shí)間。所有模糊規(guī)則,包括優(yōu)化周期時(shí)間和相位類(lèi)型的規(guī)則,在這個(gè)過(guò)程中,準(zhǔn)備以調(diào)查問(wèn)卷形式和展現(xiàn)給一些專(zhuān)家包括從德黑蘭警察局交通上校和兩名來(lái)自德黑蘭的交通組織工程師。但公路發(fā)展、交通管理卻相對(duì)落后,導(dǎo)致了交通事故與日劇增,城市里尤其突出。超聲波倒車(chē)測(cè)距儀(俗稱(chēng)電子眼)是汽車(chē)倒車(chē)防撞安全輔助裝置,能以聲音或者更為直觀(guān)的數(shù)字形式動(dòng)態(tài)顯示周?chē)系K物的情況。超聲波測(cè)距的原理一般采用渡越時(shí)間法。反之,如果兩極板間未加電壓,當(dāng)共振板接收到超聲波時(shí),將壓迫壓電晶片做振動(dòng),將機(jī)械能轉(zhuǎn)換為電信號(hào),這是它就成為超聲波接收器了。前方測(cè)距電路的輸出端接至單片機(jī)INT0端口,中斷優(yōu)先級(jí)最高,左、右測(cè)距電路的輸出通過(guò)與門(mén)IC3A的輸出接單片機(jī)的INT1端口,中斷源的識(shí)別由程序查詢(xún)來(lái)處理,中斷優(yōu)先級(jí)為先右后左。第五步:發(fā)射兩竄脈沖產(chǎn)生干擾波。nop。定時(shí)中斷服務(wù)子程序完成三方向超聲波的輪流發(fā)射,外部中斷服務(wù)子程序主要完成時(shí)間值的讀取、距離計(jì)算、結(jié)果的輸出等工作。關(guān)外部中斷0

它測(cè)量最近障礙物的距離, 并告訴給車(chē)主。目前汽車(chē)安全領(lǐng)域被動(dòng)安全研究較多,主要從安全氣囊、ABS(防抱死系統(tǒng))和懸架等方面著手,以保證駕乘人員的安全。邏輯交通控制滿(mǎn)足所有的交通燈控制的需求,并能回答的能力問(wèn)題。當(dāng)天的參數(shù)是在日歷基礎(chǔ)上基于假期和正常的一天與周期時(shí)間量的關(guān)系預(yù)定義的。第4節(jié)介紹交通燈控制的模糊本體的建設(shè)。關(guān)鍵詞:模糊本體,智能代理,智能交通系統(tǒng)(ITS),交通信號(hào)燈控制(TLC),孤立的十字路口,圖像處理,人工神經(jīng)網(wǎng)絡(luò)作為城市交通增加的結(jié)果,道路網(wǎng)絡(luò)的能力有限和發(fā)展交通工具和方法的技術(shù)方面,許多實(shí)體,關(guān)系,情況和規(guī)則已經(jīng)進(jìn)入交通燈控制域和轉(zhuǎn)化成為一個(gè)知識(shí)領(lǐng)域。我們對(duì)自己的聚類(lèi)算法模型和其它使用綠燈模擬器的系統(tǒng)做了比較。本文介紹了一個(gè)智能交通的系統(tǒng)的設(shè)計(jì)。當(dāng)正在進(jìn)行一個(gè)變革管理計(jì)劃時(shí),有些問(wèn)題是需要考慮的。截至2005年2月,%,雖然這個(gè)數(shù)字看起來(lái)是很低,但如果這和美國(guó)的勞動(dòng)人口相結(jié)合,那是一個(gè)多么驚人的數(shù)字,并且還有很多企業(yè)的離職率是沒(méi)有統(tǒng)計(jì)上去的。那么為什么一些企業(yè)面臨著離職率的上升?總的來(lái)說(shuō),美國(guó)勞工統(tǒng)計(jì)局最近發(fā)現(xiàn)40%的員工離職是因?yàn)樗麄冇X(jué)得在公司里面缺乏賞識(shí)和關(guān)心,并且沒(méi)有團(tuán)隊(duì)合作,產(chǎn)生嚴(yán)重的負(fù)荷。變革管理可以:降低生產(chǎn)力的損失鼓勵(lì)抵抗變革
