Unfinished at the time of Marx's death in 1883 and first published with a preface by Frederick Engels in 1894, the third volume of Das Kapital strove to combine the theories and...
Object Detection with Discriminatively Trained Part-Based Models
We describe an object detection system based on mixtures of multiscale deformable part models. Our system is able to represent highly variable object classes and achieves state-...
Free Energy of a Nonuniform System. I. Interfacial Free Energy
It is shown that the free energy of a volume V of an isotropic system of nonuniform composition or density is given by : NV∫V [f0(c)+κ(▿c)2]dV, where NV is the number of molecul...
Orbital angular momentum of light and the transformation of Laguerre-Gaussian laser modes
Laser light with a Laguerre-Gaussian amplitude distribution is found to have a well-defined orbital angular momentum. An astigmatic optical system may be used to transform a hig...
