A DDR3 DIMM has three notches - one on each end (which matches the retaining springs on the motherboard socket) - and one offset notch on the row of connector pins - to ensure you insert it the correct way into the socket.

Change a cognos report to a new different catalog?

You can do it with a macro. Dim ImpAppObject as Object Dim ImpRepObject as Object Dim strPath as String Dim strExtension as String Dim strFolder as String Dim PromptVal As String Dim strPath1 as String Sub Main() strPath = "M:\Algemeen\Werkmap\In" strFolder = dir("M:\Algemeen\Werkmap\In\*.IMR") strPath1 = "M:\Algemeen\Werkmap\Uit" Set ImpAppObject = CreateObject("CognosImpromptu.Application") ImpAppObject.Visible 0 ImpAppObject.OpenCatalog "L:\BESTMATE 3.014PRPI.CAT","Creator" Do While StrFolder <>"" Set ImpRepObject = ImpAppObject.OpenReportNoExecute(strpath & strfolder) ImpRepObject.SaveAs strpath1+strfolder ImpRepObject.CloseReport strFolder = Dir loop ImpAppObject.Quit Set ImpAppObject = Nothing End Sub


How to compute temperature?

The temperature is calculated by the formula KE = dim/2 N k T, where KE = total kinetic energy of the group of atoms (sum of 1/2 m v^2), dim = 2 or 3 = dimensionality of the simulation, N = number of atoms in the group, k = Boltzmann constant, and T = temperature.

How do you find equation for a pyramid of oranges stacked 1 2x2 3x3 4x4?

The equation for n layers is S(n) = n(n+1)(2n+1)/6It is simplest to prove it by induction.When n = 1,S(1) = 1*(1+1)(2*1+1)/6 = 1*2*3/6 = 1.Thus the formula is true for n = 1.Suppose it is true for n = m. That is, for a pyramid of m levels,S(m) = m*(m+1)*(2m+1)/6Then the (m+1)th level has (m+1)*(m+1) oranges and soS(m+1) = S(m) + (m+1)*(m+1)= m*(m+1)*(2m+1)/6 + (m+1)*(m+1)= (m+1)/6*[m*(2m+1) + 6(m+1)]= (m+1)/6*[2m^2 + m + 6m + 6]= (m+1)/6*[2m^2 + 7m + 6]= (m+1)/6*(m+2)*(2m+3)= (m+1)*(m+2)*(2m+3)/6= [(m+1)]*[(m+1)+1)]*[2*(m+1)+1]/6Thus, if the formula is true for n = m, then it is true for n = m+1.Therefore, since it is true for n =1 it is true for all positive integers.

What is m over m to the -4 power?

It depends on the interpretation of the question: Trivially, (m/m)-4 = 1-4 = 1. More interestingly, m-a = 1/ma or ma = 1/m-a So, m/m-4 = m*(1/m-4) = m*(m4) = m5
