on-line MCMC Bayesian Model Selection
This demo demonstrates how to use the sequential Monte Carlo algorithm with reversible jump MCMC steps to perform model selection in neural networks. We treat both the model dimension (number of neurons) and model parameters as unknowns. The derivation and details are presented in: Christophe Andrieu, Nando de Freitas and Arnaud Doucet. Sequential Bayesian Estimation and Model Selection Applied to Neural Networks . Technical report CUED/F-INFENG/TR 341, Cambridge University Department of Engineering, June 1999. After downloading the file, type "tar -xf version2.tar" to uncompress it. This creates the directory version2 containing the required m files. Go to this directory, load matlab5 and type "smcdemo1". In the header of the demo file, one can select to monitor the simulation progress (with par.doPlot=1) and modify the simulation parameters.

c語言怎么編游戲
純真童趣的《泡泡堂》,還有武林情仇,笑傲江湖的《劍俠情緣on
line》.它是e時(shí)代常談的話題,是交互式娛樂的主力軍,是一種
高層次的綜合藝術(shù),更是一個(gè)民族的文化,世界觀的全新傳播方式
.作為游戲玩家的我們,是不是想設(shè)計(jì)一個(gè)屬于自己的游戲呢?
愛玩是人的天性,而C語言是我們計(jì)算機(jī)專業(yè)都要學(xué)習(xí)的一門基礎(chǔ)
學(xué)科.一般來說,是比較枯燥的.那么,我們能不能通過編一些小
游戲來提高它的趣味性呢?這樣學(xué)習(xí)程序設(shè)計(jì),就不會是一件艱苦
,枯燥的事,它變得象電腦游戲一樣充滿好奇,富有樂趣.這正是
我發(fā)貼的目的.

PCB設(shè)計(jì)問題集錦
問:PCB圖中各種字符往往容易疊加在一起,或者相距很近,當(dāng)板子布得很密時(shí),情況更加嚴(yán)重。當(dāng)我用Verify Design進(jìn)行檢查時(shí),會產(chǎn)生錯(cuò)誤,但這種錯(cuò)誤可以忽略。往往這種錯(cuò)誤很多,有幾百個(gè),將其他更重要的錯(cuò)誤淹沒了,如何使Verify Design會略掉這種錯(cuò)誤,或者在眾多的錯(cuò)誤中快速找到重要的錯(cuò)誤。 答:可以在顏色顯示中將文字去掉,不顯示后再檢查;并記錄錯(cuò)誤數(shù)目。但一定要檢查是否真正屬于不需要的文字。
問: What’s mean of below warning:(6230,8330 L1) Latium Rule not checked: COMPONENT U26 component rule.答:這是有關(guān)制造方面的一個(gè)檢查,您沒有相關(guān)設(shè)定,所以可以不檢查。
問: 怎樣導(dǎo)出jop文件?答:應(yīng)該是JOB文件吧?低版本的powerPCB與PADS使用JOB文件。現(xiàn)在只能輸出ASC文件,方法如下STEP:FILE/EXPORT/選擇一個(gè)asc名稱/選擇Select ALL/在Format下選擇合適的版本/在Unit下選Current比較好/點(diǎn)擊OK/完成然后在低版本的powerPCB與PADS產(chǎn)品中Import保存的ASC文件,再保存為JOB文件。
問: 怎樣導(dǎo)入reu文件?答:在ECO與Design 工具盒中都可以進(jìn)行,分別打開ECO與Design 工具盒,點(diǎn)擊右邊第2個(gè)圖標(biāo)就可以。 問: 為什么我在pad stacks中再設(shè)一個(gè)via:1(如附件)和默認(rèn)的standardvi(如附件)在布線時(shí)V選擇1,怎么布線時(shí)按add via不能添加進(jìn)去這是怎么回事,因?yàn)橛袝r(shí)要使用兩種不同的過孔。答:PowerPCB中有多個(gè)VIA時(shí)需要在Design Rule下根據(jù)信號分別設(shè)置VIA的使用條件,如電源類只能用Standard VIA等等,這樣操作時(shí)就比較方便。詳細(xì)設(shè)置方法在PowerPCB軟件通中有介紹。
問:為什么我把on-line DRC設(shè)置為prevent..移動元時(shí)就會彈出(圖2),而你們教程中也是這樣設(shè)置怎么不會呢?答:首先這不是錯(cuò)誤,出現(xiàn)的原因是在數(shù)據(jù)中沒有BOARD OUTLINE.您可以設(shè)置一個(gè),但是不使用它作為CAM輸出數(shù)據(jù).
問:我用ctrl+c復(fù)制線時(shí)怎設(shè)置原點(diǎn)進(jìn)行復(fù)制,ctrl+v粘帖時(shí)總是以最下面一點(diǎn)和最左邊那一點(diǎn)為原點(diǎn) 答: 復(fù)制布線時(shí)與上面的MOVE MODE設(shè)置沒有任何關(guān)系,需要在右鍵菜單中選擇,這在PowerPCB軟件通教程中有專門介紹.
問:用(圖4)進(jìn)行修改線時(shí)拉起時(shí)怎總是往左邊拉起(圖5),不知有什么辦法可以輕易想拉起左就左,右就右。答: 具體條件不明,請檢查一下您的DESIGN GRID,是否太大了.
問: 好不容易拉起右邊但是用(圖6)修改線怎么改怎么下面都會有一條不能和在一起,而你教程里都會好好的(圖8)答:這可能還是與您的GRID 設(shè)置有關(guān),不過沒有問題,您可以將不需要的那段線刪除.最重要的是需要找到布線的感覺,每個(gè)軟件都不相同,所以需要多練習(xí)。
問: 尊敬的老師:您好!這個(gè)圖已經(jīng)畫好了,但我只對(如圖1)一種的完全間距進(jìn)行檢查,怎么錯(cuò)誤就那么多,不知怎么改進(jìn)。請老師指點(diǎn)。這個(gè)圖在附件中請老師幫看一下,如果還有什么問題請指出來,本人在改進(jìn)。謝!!!!!答:請注意您的DRC SETUP窗口下的設(shè)置是錯(cuò)誤的,現(xiàn)在選中的SAME NET是對相同NET進(jìn)行檢查,應(yīng)該選擇NET TO ALL.而不是SAME NET有關(guān)各項(xiàng)參數(shù)的含義請仔細(xì)閱讀第5部教程.
問: U101元件已建好,但元件框的拐角處不知是否正確,請幫忙CHECK 答:元件框等可以通過修改編輯來完成。問: U102和U103元件沒建完全,在自動建元件參數(shù)中有幾個(gè)不明白:如:SOIC--》silk screen欄下spacing from pin與outdent from first pin對應(yīng)U102和U103元件應(yīng)寫什么數(shù)值,還有這兩個(gè)元件SILK怎么自動設(shè)置,以及SILK內(nèi)有個(gè)圓圈怎么才能畫得與該元件參數(shù)一致。
答:Spacing from pin指從PIN到SILK的Y方向的距離,outdent from first pin是第一PIN與SILK端點(diǎn)間的距離.請根據(jù)元件資料自己計(jì)算。

Mega16是一款采用先進(jìn)RISC精簡指令,內(nèi)置A/D的8位單片機(jī),可支持低電壓聯(lián)機(jī) Flash和EEPROM 寫入功能;同時(shí)還支持 Basic和C 等高級語言編程。用它設(shè)計(jì)電子時(shí)鐘不僅成本低,硬件簡單,而且很容易實(shí)現(xiàn)系統(tǒng)移植。介紹了如何利用AVR系列單片機(jī)Mega16及1602字符液晶來設(shè)計(jì)電子時(shí)鐘的方法,同時(shí)給出了相應(yīng)的電路原理及部分語言程序。
Abstract:
?Mega16 is a high-performance, low power consumption, the use of advanced RISC concise instructions, built-in A/D 8-bit microcontrollers, the on-line support for low-voltage Flash, EEPROM write function. Except Mega16 also support the Basic, C, and other high-level language programming.The electronic clock which is deisgned by Mega16 is not only low-cost, simple hardware, but easy to achieve system migration.The design method of electrioic clock based on the AVR Mega16 and character LCD1602 is introduced in this paper,and the corresponding circuit electrionic and some language program are given.

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C-buses that connect to the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus master and are usedto select one master at a time. Either master at any time can gain control of the slavedevices if the other master is disabled or removed from the system. The failed master isisolated from the system and will not affect communication between the on-line masterand the slave devices on the downstream I2C-bus.
