Read MoreHow to find an element using the attribute “class name” in Selenium?
We can find an element using the attribute class name with Selenium webdriver using the locators - class name, css, or xpath. To identify the element with css, the expression should be tagname[class='value'] and the method to be used is By.cssSelector. To identify the element with xpath, the expression should be //tagname[@class='value']. Then, we have to use the method By.xpath to locate it. To locate an element with a locator class name, we have to use the By.className method. Let us look at the html code of an element with class attribute − Syntax WebElement e = driver. findElement(By.className("input")); ...
Read MoreProperties of Convolution in Signals and Systems
ConvolutionConvolution is a mathematical tool for combining two signals to produce a third signal. In other words, the convolution can be defined as a mathematical operation that is used to express the relation between input and output an LTI system.Consider two signals $\mathit{x_{\mathrm{1}}\left( t\right )}$ and $\mathit{x_{\mathrm{2}}\left( t\right )}$. Then, the convolution of these two signals is defined as$$\mathrm{ \mathit{\mathit{y\left(t\right)=x_{\mathrm{1}}\left({t}\right)*x_{\mathrm{2}}\left({t}\right)\mathrm{=}\int_{-\infty }^{\infty }x_{\mathrm{1}}\left(\tau\right)x_{\mathrm{2}}\left(t-\tau\right)\:d\tau=\int_{-\infty }^{\infty }x_{\mathrm{2}}\left(\tau \right)x_{\mathrm{1}}\left(t-\tau\right)\:d\tau }}}$$Properties of ConvolutionContinuous-time convolution has basic and important properties, which are as follows −Commutative Property of Convolution − The commutative property of convolution states that the order in which we convolve two signals does not ...
Read MoreConstruct a Predictive Parsing table for the following grammar & also check whether string nid + id * id is accepted or not.
Problem − Consider the following grammar − E → TE′ E′ → +TE′|ε T′ → FT′ T′ → FT′|ε F → (E)|id Solution − Step1− Elimination of Left Recursion & perform Left Factoring As there is no left recursion in Grammar so, we will proceed as it is. Also, there is no need for Left Factoring. Step2− Computation of FIRST FIRST(E) = FIRST(T) = FIRST(F) = {(, id} FIRST (E′) = {+, ε} FIRST (T′) = {*, ε} Step3− Computation of FOLLOW FOLLOW (E) = FOLLOW(E′) = {), $} FOLLOW (T) = FOLLOW(T′) = {+, ), $} FOLLOW (F) = ...
