Spatial Interference Cancelation for Mobile Ad Hoc Networks: Perfect CSI
, 2008 Interference between nodes directly limits the capacity of mobile ad hoc networks. This paper focuses on spatial interference cancelation with perfect channel state information (CSI), and analyzes the corresponding network capacity.

Stationary values of the transmission ratio of the planar fourbar
Vietnam Journal of Mechanics, 2008 The transmission ratio of the planar fourbar, i.e. the ratio of the angular velocities of input link and output link, is a function of the input angle. Freudenstein [1] showed how to calculate stationary values of the transmission ratio.

Transmission Ratio Distortion in Extended Families
, 2015 A statistical departure from Mendel's law of segregation is known as transmission ratio distortion (TRD). Though well documented in many other organisms, the extent of TRD and its influence in the human genome remains incomplete. Using GAW19 whole genome sequence (WGS) data from 20 large Mexican American pedigrees, our goal was to identify potentially ...

Novel infinitely Variable Transmission allowing efficient transmission ratio variations at rest
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015 Recent studies showed that Continuously Variable Transmissions (CVT) and Infinitely Variable Transmissions (IVT) can considerably improve the locomotion efficiency in legged robot. A CVT is a transmission whose ratio can be continuously varied and an IVT is a transmission whose ratio can be continuously varied from positive to negative values. However,

Theory of Optical Transmission through Elliptical Nanohole Arrays
, 2007 We present a theory which explains (in the quasistatic limit) the experimentally observed [R. Gordon, {\it et al}, Phys. Rev. Lett. {\bf 92}, 037401 (2004)] squared dependence of the depolarization ratio on the aspect ratio of the holes, as well as other
