用NTC熱敏電阻做溫度采集:本應(yīng)用例實現(xiàn)NTC熱敏電阻器對溫度的測量。熱敏電阻器把溫度的變化轉(zhuǎn)換為電阻阻值的變化，再應(yīng)用相應(yīng)的測量電路把阻值的變化轉(zhuǎn)換為電壓的變化；SPMC75F2413A內(nèi)建8路ADC可以把模擬的電壓值轉(zhuǎn)換為數(shù)字信號，對數(shù)值信號進(jìn)行處理可以得到相應(yīng)的溫度值。1.2 熱敏電阻器熱敏電阻有電阻值隨溫度升高而升高的正溫度系數(shù)（positive Temperature Coefficient簡稱PTC）熱敏電阻和電阻值隨溫度升高而降低的負(fù)溫度系數(shù)（Negative Temperature Coefficient簡稱NTC）熱敏電阻。NTC熱敏電阻器，是一種以過渡金屬氧化物為主要原材料，采用電子陶瓷工藝制成的熱敏半導(dǎo)體陶瓷組件。這種組件的電阻值隨溫度升高而降低，利用這一特性可制成測溫、溫度補(bǔ)償和控溫組件，又可以制成功率型組件，抑制電路的浪涌電流。

We offer a broad line of high performance low dropout (LDO) linear regulators with fasttransient response, excellent line and load regulation, and very wide input voltage rangefrom 0.9V to 100V. Output currents range from 20mA to 10A, with positive, negative andmultiple output versions available. Many devices offer output voltage operation <0.8V andsome feature operation as low as 0V, even with a single supply. Most are stable with ceramicoutput capacitors. LDO regulators can be applied in virtually any application.

ICA can be used in brain activation studies to reduce the number of dimension and filter out independent and interesting activations. This demonstration shows two studies. One provided by Hvidovre Universitets Hospital, Denmark, that consists of fMRI scannings of humans. Another provided by the EU sponsored MAPAWAMO project from fMRI scannings of monkeys. In the demo comparison between icaMS, icaML, icaMF, icaMF (positive sources) and PCA can be made. More detailes can found in [2].

數(shù)字運(yùn)算，判斷一個數(shù)是否接近素數(shù) A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

2^x mod n = 1 acm競賽題 Give a number n, find the minimum x that satisfies 2^x mod n = 1. Input One positive integer on each line, the value of n. Output If the minimum x exists, print a line with 2^x mod n = 1. Print 2^? mod n = 1 otherwise. You should replace x and n with specific numbers. Sample Input 2 5 Sample Output 2^? mod 2 = 1 2^4 mod 5 = 1

平均因子分解法，適用于正定矩陣First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition.
