Particulate matter emission is one of the major air pollution problems of coal fired power plants. Though fine particles constitute a smaller fraction by weight of the total suspended particle matter in typical particle emissions, they are considered potentially hazardous to health because of their high probability of deposition in deeper parts of the respiratory tract. Electrostatic precipitat...

An open quantum system in steady state rho(ss) can be represented by a weighted ensemble of pure states rho(ss) = [equation: see text] in infinitely many ways. A physically realizable (PR) ensemble is one for which some continuous measurement of the environment will collapse the system into a pure state /psi(t)>, stochastically evolving such that the proportion of time for which /psi(t)> = /psi...

To every matroid, we associate a class in the K-theory of the Grassmannian. We study this class using the method of equivariant localization. In particular, we provide a geometric interpretation of the Tutte polynomial. We also extend results of the second author concerning the behavior of such classes under direct sum, series and parallel connection and two-sum; these results were previously o...

– Filter, any modification of the signal according to design specifications. – Frequency selectivity – Causal filters (real time without delay) – Note ideal filters are not realizable. We can’t have perfect magnitude response. For example, the ideal low pass filter is not realizable because it requires infinite length sinc function. We would like causal filters: – IIR ok – FIR sometimes even be...

A sequence of non-negative integers (φn)∞n=1 is said to be realizable if there is a map T of a set X such that φn = #{x : T nx = x}. We prove that any realizable sequence can be realized by a C diffeomorphism of T2.

Based on the physics underlying turbulence anisotropy in the equilibrium and nonequilibrium limits, a new physically-based, fully-realizable, nonequilibrium k − 2 RANS model has been developed. The model is based on an effective strain rate tensor that accounts for the strain history to which the turbulence has been subjected. This new model is applied to four distinctly different test cases fo...

Bu çalışmada, çatı eğim açısının 15°, 30° ve 45° saçak 0°, 30°, 60° olduğu beşik çatılı alçak bina modelleri etrafında sürekli rejimdeki üç boyutlu akış alanları, Reynolds sayısının 40000 değeri için Standard k-ε, RNG k-ε Realizable türbülans ile hesaplanmıştır. Çatı açılarındaki değişikliğin basınç dağılımları üzerindeki etkisi model yüzeylerinde ortalama katsayısı şeklinde incelenmiştir. Sayı...
