8 A curve y = f(x) has a stationary point at P(3, -10). It is given that f'(x) =2x2+kx-12, where k is a constant.(i) Show that k=-2 and hence find the x-coordinate of the other stationary point. Q.[4](ii) Find f"(x) and determine the nature of each o...
Minimax robust nonstationary signal estimation based on a p-point uncertainty model - Matz, Hlawatsch () Citation Context ... averaging, which results in signal processing methods with enhanced statistical robustness. In fact, this robuston paradigm generalizes a previously proposed scheme that is ...
The liquid crystalline nature of the mesophase can be maintained at temperatures up to 16 °C below the melting point. This fact allows an almost complete separation of m- and p-xylene, which was not accomplished previously with PAA on packed columns. The importance of increasing relative ...
only candidate for extreme point. The 1 st principal minors are –2, -3. The 1 st leading principal minor is –2. The 2 nd principal minors are 2 (confirm this). The 2 nd leading principal minor is +2. Therefore, this function satisfies the tests for a local maximum. Note also...
We find that there exists a threshold value ξ 0 such that the positive equilibrium point of the model becomes unstable when the prey-taxis rate ξξ 0 , hence the taxis-driven Turing instability occurs. Furthermore, by applying Crandall–Rabinowitz bifurcation theory, the existence, the ...
(i.e. the gradient is zero) you have a stationary point. In short: find the 1 st differential, put it equal to zero and solve. Examples: Find the stationary point on the curve : Step 1: Differentiate to give: Step 2: Put this equal to zero: Step 3: Solve: We now ...
a part extending from an upper edge of an opening 7 to a magnetic shield 5 attaching end point is formed as a tank wall 10a having an island form isolated so that its tank wall 10a maintains a space at an optional intervals to the tank wall 10b of a general part between magnetic shiel...
This could point to higher iron levels in the (p)ppGpp0 mutant, which might be responsible for the growth delay in RPMI (Fig. 3C). Growth in RPMI medium was shown to mimic infection conditions of S. aureus in human plasma resulting in higher expression levels of iron-regulated genes [...
摘要: From the mathematical point of view, we can describe a given signal in many different ways, as the function of time, or as the function of frequency, which tells us how quickly signal magnitude changed.会议名称: International Radar Symposium India - 2011 (IRSI-11): Bangalore (IN)....
In other words, from a physical point of view, when the base tension of the string modeled by the equation is zero: a very realistic case. Last but not least no monotonicity assumption is required on $M$ and also this aspect makes the models more believable in several physical applications...
