The Kriging weights w_i1,w_i2,w_i3,…w_ik can be used to estimate the fair value of VA contracts x ⃑_i by the following formula, y ̂_i=∑_(j=1)^k▒〖w_ij∙y_j 〗. The kriging weights can be calculated by the following linear equations, Where the is a control variable, which is used to make sure that ∑_(j=1)^k▒w_ij =1. V_rs=α+exp(-3/β D(z ⃑_r,z ⃑_s,λ)),r,s=1,2,3,…,k, D_ij=α+exp(-3/β D(x ⃑_i,z ⃑_j,λ)),j=1,2,3,…,k, The D(.) function is the distance function mentioned in the clustering section…
Problem: Apparatus 1: what is the relationship between height of release and the initial velocity? Apparatus 2: What is the relationship between length of the ball catcher and the final velocity of the system? Additional question: What is the percentage error of the initial velocity calculated using momentum and kinematics? Percentage error between theoretical initial velocity and experimental initial velocity? How much energy is lost? note: the initial velocity calculated using kinematics…
The general model introduced in Fig.4.10 is commonly used to design stable high-order modulators. If a chain of integrators is used to form the loop filter, two main modulators typologies exist [1, 5, 8]: a cascade of M delaying integrators is used to form the filter, where the feedback and the input signals are being fed to each integrator input with different weight factors a_i and b_i (Fig.4.11). The transfer function of the signal filter, L_0, is: while the feedback filter L_1 can be…
Axiom of choice was formulated by Zermelo in 1904 and is known as Zermelo’s axiom of choice. This axiom stated that we can choose a member from each set in a collection of nonempty disjoint sets, C (Schechter, 2009). Additionally, according to Janes (2008), there exists a set X which consisting of one element taken from each set belonging to Y given that any nonempty set Y members are pairwise disjoint sets. Taking a role as a basic assumption used in many parts of mathematics as stated by…
Q1) What type of reinforcement schedule does random drug testing represent? Is this type of schedule typically effective or ineffective? The type of reinforcement schedule that random drug testing represents is the Variable-Interval(VI) schedule of reinforcement. In Variable Interval schedule a response is rewarded after an unpredictable amount of time has passed. This type of schedule is done randomly and is unexpected. The word random used in this case itself represents the schedule. Variable…
Table 4.2 System suitability results for Lamivudine, Zidovudine and Nevirapine Parameters Lamivudine Zidovudine Nevirapine Retention time 2.327 2.864 5.608 Area 212473 338930 228426 USP Plate count 2715.09 3350.07 4979.51 USP Tailing 1.38 1.32 1.18 4.3.1.2 Linearity A linear correlation coefficient factor was obtained between the concentrations of Lamivudine, Zidovudine and Nevirapine versus the peak area. The calibration curves were linear for concentrations between 15-150 µg/mL. The linearity…
6.5 Granger Causality Granger causality statistics determine whether past values of one variable helps to predict another variable. For example, if the lagged value of the independent variable X, help in predicting the value of the explanatory variable Y_(t+1), then X granger causes the Y. On the other hand, if the independent variable X does not help to predict Y, then the coefficients on the lags of X will all be zero in the reduced form Y equation. 7. Empirical results 7.1 Optimal lag…
Strength All the data obtained from this experiment is plotted on the graph. The accuracy and precision can be determined from the graph. Based on the graph , as the line do not pass the origin , it can be deducted that the result is fairly accurate. Since there are few outliers on the graph , the precision of this graph is moderate. Accuracy of the graph is affected by systematic errors while the precision is affected by random errors. A few measures had been taken prior in getting more…
Some of the similarities that I saw in the data are: 1. An increase in temperatures began in January and ended in July. After July, the temperatures decreased. 2. With the data I worked with, I noticed that the median tends to be around 50 to 60 degrees. 3. Once the data hits a certain point, like a max, the data values decreased. I was able to find the first similarity and the third similarity when I looked at the line graphs. Looking at the line graphs, I was able to see where the data…
