http://www.maplesoft.com/applications/view.aspx?SID=154100&ref=Feed
In 1935, Einstein, Podolsky and Rosen published a paper revealing a counter-intuitive situation in quantum mechanics which was later known as the EPR paradox. The phenomenon involved an entangled state., which Schrodinger called "not one but the characteristic trait of quantum mechanics." In textbooks, entanglement is often presented in abstract notations. In popular accounts of quantum mechanics, entanglement is sometimes portrayed as a mystery or even distorted in a nearly pseudoscientific fashion. In this worksheet, we use Maple's LinearAlgebra package to represent quantum states and measurements in matrix form. The famous Bell's inequality and teleportation can be understood using elementary matrix operations.<img src="/view.aspx?si=154100/8df7b465a1583cedab7e3e6452644591.gif" alt="Matrix Representation of Quantum Entangled States: Understanding Bell's Inequality and Teleportation" align="left"/>In 1935, Einstein, Podolsky and Rosen published a paper revealing a counter-intuitive situation in quantum mechanics which was later known as the EPR paradox.

Long term measurement of heart rate furnishes important information of cardiac anomalies. During a period of about 24 hours pulse rate of a patient at the University Hospital Aachen has been measured. Thus, we have a lots of pulse values, which are important for a medical doctor treating sick patients. We use Maple to analyze this data. At first the given data have been interpolated by cubic spline functions. Then, these functions have been approximated by nonlinear regression and also by Fourier series.<img src="/view.aspx?si=154087/pulsevalues.png" alt="Pulse Values from Long Term Measurement" align="left"/>Long term measurement of heart rate furnishes important information of cardiac anomalies.

This application calculates the ionization constant of water using the formulation ratified by the International Association for the Properties of Water and Steam (IAPWS) in 2007. The formula is semi-empirical, and employs temperature and density as states. This application, however, asks the user to enter temperature and pressure as states, and uses that information to calculate the density of water. This is a more practical specification of states.<img src="/view.aspx?si=154073/81c8f7d9a73d606bb26d75f871d0f3ab.gif" alt="Ionization Constant of H2O as function of pressure and temperature" align="left"/>This application calculates the ionization constant of water using the formulation ratified by the International Association for the Properties of Water and Steam (IAPWS) in 2007.

If an object is subjected to several forces having different magnitudes and act in different directions, how can determine the magnitude and direction of the resultant total force on the object? Forces are vectors and should be added according to the definition of the vector sum. Engineering dealing with many quantities that have both magnitude and direction and can be expressed and analyzed as vectors.

http://www.maplesoft.com/applications/view.aspx?SID=154068&ref=Feed
An advanced exergetic analysis converts the most important limitations of the conventional analysis into strengths. An advanced analysis provides options to estimate (a) the real potential for improving the components (splitting the exergy destruction into unavoidable and avoidable parts); and (b) the mutual interdependencies among the exergy destructions within the components of a system (splitting the exergy destruction into endogenous and exogenous parts). Distinctions between avoidable and unavoidable exergy destruction on one side and endogenous and exogenous exergy destruction on the other side (with a further splitting of the exogenous exergy destruction) allow engineers to focus on the thermodynamic inefficiencies that can be avoided by simultaneously considering the interactions among system components. The avoidable endogenous and the avoidable exogenous exergy destructions provide the best guidance for improving the thermodynamic performance of energy conversion systems.
The drawbacks associated with the advanced exergetic analysis are the need for simulating some non-standard cycles (e.g., so-called hybrid cycles), the large number of required simulations and the associated engineering time.
Within this Maple-aided analysis, the potential for improving the thermodynamic efficiency of components and the overall vapor-compression refrigeration system as well as the interactions among components and their effect on the exergy destruction within each component can be estimated.<img src="/view.aspx?si=154068/Vv-27-adv-ex-eng-SimpleRefrigerationCycle.png" alt="Advanced Exergetic Analysis of Simple Vapor Compression Refrigeration Cycle" align="left"/>An advanced exergetic analysis converts the most important limitations of the conventional analysis into strengths.

http://www.maplesoft.com/applications/view.aspx?SID=154065&ref=Feed
In the event that a high COP of a refrigeration cycle is of greater importance compared to other factors, it is possible to significantly increase the COP of a basic cycle through the use of a multistage vapor compression cycle. This is especially true when the pressure ratio between the heat rejection and heat absorption pressures is large 5 or more.
Multistaging involves one or more intermediate pressures between the heat rejection and heat absorption pressures, and a series of compressors operating between successive pressure intervals.
One type of multi-compressor vapor compression cycle includes a mixing chamber where saturated vapor from the flash chamber mixes with the vapor leaving the low pressure stage compressor. This vapor-mixing chamber acts as a regenerative intercooler since it cools the superheated vapor leaving the low-pressure stage compressor using lower temperature saturated workin fluid, mixing the two prior to the next stage of compression.
This type of refrigeration cycle is analysed in the following calculation.<img src="/view.aspx?si=154065/Two-Stage_Vapor_Compression_Refrigeration_Cycle_with_Flash_Chamber_and_Separate_Vapor_Mixing_Intercooler.png" alt="Thermodynamic Calculations of Two-Stage Vapor Compression Refrigeration Cycle with Flash Chamber and Separate Vapor Mixing Intercooler" align="left"/>In the event that a high COP of a refrigeration cycle is of greater importance compared to other factors, it is possible to significantly increase the COP of a basic cycle through the use of a multistage vapor compression cycle.
