This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active Server Pages environment, but most of the techniques discussed have equivalents in other database environments. It should be viewed as a "follow up", or perhaps an appendix, to the previous paper, "Advanced SQL Injection". The paper covers in more detail some of the points described in its predecessor, providing examples to clarify areas where the previous paper was perhaps unclear. An effective method for privilege escalation is described that makes use of the openrowset function to scan a network. A novel method for extracting information in the absence of helpful error messages is described the use of time delays as a transmission channel. Finally, a number of miscellaneous observations and useful hints are provided, collated from responses to the original paper, and various conversations around the subject of SQL injection in a SQL Server environment.

* Lightweight backpropagation neural network. * This a lightweight library implementating a neural network for use * in C and C++ programs. It is intended for use in applications that * just happen to need a simply neural network and do not want to use * needlessly complex neural network libraries. It features multilayer * feedforward perceptron neural networks, sigmoidal activation function * with bias, backpropagation training with settable learning rate and * momentum, and backpropagation training in batches.

Excel的強(qiáng)大函數(shù)功能，為我們帶來了極大方便，雖然它有200多個函數(shù)，但有時我們?yōu)閷?shí)現(xiàn)一項(xiàng)規(guī)定的功能，可能用到幾個函數(shù)或者采用嵌套函數(shù)，這樣應(yīng)用起來，也不太方便。其實(shí)對于我們經(jīng)常用到的功能，我們可以創(chuàng)建自定義函數(shù)UDF(User—defined function)，它的運(yùn)行與Excel中自帶的函數(shù)完全相同。建立自定義函數(shù)有以下幾個優(yōu)點(diǎn)：建立自己特殊的功能和名稱的函數(shù)；能將復(fù)雜的、嵌套的、多個原有的函數(shù)組合在一起，發(fā)揮更大的威力。

documentation for optimal filtering toolbox for mathematical software package Matlab. The methods in the toolbox include Kalman filter, extended Kalman filter and unscented Kalman filter for discrete time state space models. Also included in the toolbox are the Rauch-Tung-Striebel and Forward-Backward smoother counter-parts for each filter, which can be used to smooth the previous state estimates, after obtaining new measurements. The usage and function of each method are illustrated with five demonstrations problems. 1
