Ci Definition and 18 Threads

I have a single cylinder 5kW diesel generator to use for fuel efficiency and emissions reductions improvement experiments. I built an emulsifier out of an old drill press and paint cans. It's basically just a spinning cylinder inside another cylinder to get a lot of shearing force. The...

Writing about Engines and just muddled up diagrams and confused now. Which PV diagrams is for Compression Ignition and which one for Compression Ignition. I think one on left is CI and right SI. Cheers

Because I understand that for unitary evolution, MWI is required, which suggests that for different interpretations, there may not be unitary evolution?

Suppose we measure a normalized state ##|\Psi \rangle = \alpha _0 | \lambda _0 \rangle + \alpha _1 | \lambda _1 \rangle + \alpha _2 | \lambda _2 \rangle + ...## with ##| \lambda _i \rangle## the eigenvalues of the measured observable. Is it true that, in the CI, the wavefunction collapses into...

Homework Statement 1 Curie corresponds to the number of decay in 1 gram radium-226 in 1 second. How many Bequerel is 1 Curie? Homework EquationsThe Attempt at a Solution Half life: 1600 years 1 gram = 0,001 kg = (0,001/1,660539*10^-27) u one Radium atom = 226,0260974 u Number of decays...

Suppose we fire a photon P at a polarisation filter F1, and it passes the filter, thus forcing the polarisation of P in an eigenstate M1. Subsequently, the photon falls through a polarisation filter F2, forcing P in eigenstate M2. Now, if I understand correctly, the probability of P passing F2...

Homework Statement Suppose we want to estimate a sample proportion to within 0.05 with 95% confidence, how large will the sample have to be? There is no other information about the distributions of the population or the sample. How do I approach this problem? Homework Equations See...

For a molecule of n nuclei and x total electrons, how can I work out how much computing power or processing time is required for an exact Full CI calculation for that molecule?

why the mechanical efficiency and brake thermal efficiency curve increases as load increases and reaches a maximum value and then again decreases( in contand speed test)

Hi, I'm really struggling with a statistical problem: 5 people had a medical treatment, they were tested before and after using a questionnaire which recorded some numerical data. I want to analyse the before and after results to see whether there was any change, whether it is...

I have two samples, one with 21 measurements and one with 23 measurements, from a Normal distribution and I am constructing a 95% CI for the difference in the two means. I do not know the variances of the two Normal distributions. I know that \overline{X_1}-\overline{X_2}~N(\mu_1-\mu_2...

Hi, Can a few of you please review the approach I plan to take for obvious errors? I have 50 subjects and each have a measure taken on the same variable before and after treatment. So, this is standard paired t-test time, but what I am actually interested in is the variance of the treatment...

Hi, I running a full CI calculation for low Z elements (up to Ne) in order to obtain the lowest lying electronic energy levels. I can't seem to get correct results even though I'm using 1-electron states from first 4-6 electron shells. I am also using singly and doubly excited...

Would it be accurate to say MWI is holding strong in the preferred interpretation, CI is dying out (if not dead already), and BM is continuing to be accepted by more researchers (or better yet, it is being studied by more physicists now more than ever)?

Homework Statement The half-life of an isotope of phosphorus is 14 days. If sample contains 2.9 × 10^16 decays such nuclei, determine its activity. Answer in units of Ci. Homework Equations / The Attempt at a Solution I know that one Ci is equal to 3.7*10^10 bq (or decay per second), I'm...

Homework Statement A 95% CI for the population proportion of professional tennis players who earn more than $2 millions a year is found to be [0.82, 0.88]. Given this information the sample size that was used was approximately A) 545 B) 382 C) 233 D) 378 Answer: A) 545 Homework...

ok now my practicals are 15 days away and i n my friends constantly discuss about advantages and disadvantages of several combinations like 2-stroke SI engine with supercharging or 4stroke CI with CRDi etc etc. since people here are more experienced and have far more facilities than i do, i want...

energy from single point rather than expectation integral in Full CI calculation?? Hi, i guess this is kind of a stupid line of thought... if you get a wavefunction, say from a Hartree-Fock calculation, you can find your energy by calculating the expectation value of the hamiltonian. well...
