 Proper Orthogonal Decomposition  
 Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. The number of principal components is less than or equal to the number of original variables. This transformation is defined in such a way that the first principal component has the largest possible variance (that is, accounts for as much of the variability in the data as possible), and each succeeding component in turn has the highest variance possible under the constraint that it is orthogonal to (i.e., uncorrelated with) the preceding components. The principal components are orthogonal because they are the eigenvectors of the covariance matrix, which is symmetric. PCA is sensitive to the relative scaling of the original variables.

 Microeconomics for MBAs  

This collection is based on Prof Richard McKenzie and Prof Dwight Lee's book 'Microeconomics for MBAs' and covers some of the most important foundation materials needed to be mastered by MBAs.This is the first textbook in microeconomics written exclusively for MBA students. McKenzie/Lee minimizes attention to mathematics and maximizes attention to intuitive economic thinking. The text is structured clearly and accessibly: Part I of each chapter outlines the basic theory and Part II applies this basic theory to management issues. 'Perspective' sections in each chapter provide a new line of argument or different take on a business or policy issue, and carefully chosen topics and review questions are designed to spark lively and instructive debates. The accompanying DVD contains modules of Professor McKenzie talking informally with students, and elucidates complex lines of argument as well as acting as a revision aid. Throughout the book, McKenzie and Lee aim to infuse students with the economic way of thinking in the context of a host of problems that MBA students, as future managers of real-world firms, will find relevant to their career goals.

Topics Include : Prisoner's Dilemma, Comparative Advantage, Demand, Supply, ...

 Combustion Instability  

An integrated collection in the area of combustion instability is presented. Lord Rayleigh [1] noted that the generation of thermoacoustic oscillations in combustion systems was dependant on the relative phasing between pressure and heat release oscillations. When the heat release oscillations and pressure oscillations are sufficiently in phase with one another, small amplitude pressure perturbations rapidly grow into large amplitude pressure waves. Various experiments monitotring pressure and heat release in laboratory combustors and industrial burners have confirmed the applicability of this criterion [2]. For the particular case of combustion inside a dump combustor, coherent vorical structures shed from the dump plane have been recognized as a potential source of unsteady heat release [3-6] which could couple with pressure oscillations inside the combustor leading to instability. Excess unburnt fuel trapped inside the vortex core could be ignited when the vortex, convecting away from the dump plane, strikes against the walls of the combustor or impinges on the exit nozzle. This sudden combustion of unburnt fuel leads to the generation of a very well defined heat release oscillation whose periodicity...

 Fundamentals of Fluid Mechanics  
 This collection contains various videos and notes (mostly external content) that demonstrate fundamental concepts in fluid mechanics like Aerodynamics Generation of Sound, Cavitation, Channel Flow of a Compression Fluid, Deformation of Continuous Media, Eulerian Lagrangian Description,Flow Instabilities, Flow Visualization,Fluid Dynamics of Drag,Fluid Quantity and Flow, Fundamentals-Boundary Layers,Low Reynolds Number Flow, Magnetohydrodynamics,Pressure Fields and Fluid Acceleration,Rarefied Gas Dynamics,Rheological Behavior of Fluids,Rotating Flows,Secondary Flow,Stratified Flow,Surface Tension in Fluid Mechanics, Turbulence, Vorticity, Waves in Fluids etc. The starting point of this collection contains text and photographic material related to the sound films prepared under the direction of the National Committee for Fluid Mechanics Films (NCFMF). The films, and the related text material herein, cover nearly all of the fundamental phenomena of fluid motions. The concept that brought the NCFMF into existence was the conviction that films would provide a convenient, economic, and powerful way of filling a serious educational gap. On the one hand are the concrete, experimental, perceptual phenomena of the real world of fluid motion...

 Demonstrations in Acoustics  
 This collection comprises of various demonstration videos that explain important concepts in the understanding of general concepts in Acoustics and Vibration. Because both these subjects rely heavily on physical intuition and understanding from observations, this collection especially emphasizes experimental demonstration videos. We encourage all researchers working in related areas to link heir work to this collection so as to make this an useful collection for people in the field. You can not only add your videos and documents that are already on researchusa but you can link your journal papers, patents, as well videos on youtube and other external website.
