Heat Equation from Partial Differential Equations An Introduction (Strauss) These notes were written based on a number of courses I taught over the years in the U.S.‚ Greece and the U.K. They form the core material for an undergraduate course on Markov chains in discrete time. There are‚ of course‚ dozens of good books on the topic. The only new thing here is that I give emphasis to probabilistic methods as soon as possible. Also‚ I introduce stationarity before even talking about state classification

Random Variable and Its Probability distribution “A random variable is a variable hat assumes numerical values associated with the random outcome of an experiment‚ where one (and only one) numerical value is assigned to each sample point”. “A random variable is a numerical measure of the outcome from a probability experiment‚ so its value is determined by chance. Random variables are denoted using letters such as X‚Y‚Z”. X = number of heads when the experiment is flipping a coin 20 times. There

Semantic Interoperability in the d-learning in the era of Cloud Computing: Simplicity or Complexity Introduction During recent years there has been an expansion of information system covering the same domain. These systems need more and more to communicate‚ collaborate and exchange content with each other to achieve common goals. Many domains know this revolution‚ including the learning. Learning systems have a rich and varied content must be accessible‚ sharable‚ and exchangeable while keeping

An oil refinery is located on the north bank of a straight river that is 2 km wide. A pipeline is to be constructed from the refinery to storage tanks located on the south bank of the river 6 km east of the refinery. The cost of laying pipe is $200‚000 per km over land to a point P on the north bank and $400‚000 per km under the river to the tanks. To minimize the cost of the pipeline‚ how far from the refinery should P be located? (Round your answer to two decimal places.) 1 year ago Report Abuse

Exchange Exposure Factors Affecting Euro Currency over time There are many key factors which can affect the value of the Euro currency over time. Germany’s economy seems to also be a major player in relation to the Euro currency. One of the factors differentials in inflation‚ can affect the currency as countries with lower inflation rates would have increases in the value of their currency while countries with higher inflation rates would experience depreciation in their currency. Therefore if there is
