Local bundle adjustment (LBA) has recently been introduced to estimate the geometry of image sequences taken by a calibrated camera. Its advantage over standard (global) bundle adjustment is a great reduction of computational complexity, which allows real-time performances with a similar accuracy. However, no confidence measure on the LBA result such as uncertainty or covariance has yet been in...

Theoretical views on morphogen gradients have altered dramatically with the massive arrival of molecular data regarding the establishment of graded concentrations in the embryo, and the finely tuned reading by cells of these concentration levels. I review these new perspectives, and analyze in detail two models, one pertaining to the propagation of activin in Xenopus embryos, the other to the i...

In the paper, we gave after a brief overview of free space, Bacon and CEPT SE21 propagation models, mentioned in the TETRA Direct Mode Operation (DMO) standard, the comparison of the path losses, calculated by two-ray and multi-wall models and pass losses, obtained by field measurement campaign. We found out, that the tworay model is suitable for fast estimation of the TETRA DMO signal coverage...

Mobile Adhoc Network (MANET) routing protocols facilitates the creation of dynamic reconfigurable networks without any centralized infrastructure. Due to very limited transmission range of wireless network interfaces, multi hop networks are required by node to exchange data with other nodes in the network. In recent years, large number of protocols were developed and targeted specifically at th...

The need for greater bandwidth and higher data rates will inevitably lead to the usage of the lower portion of the k-band in terrestrial communication systems. The frequency band from 18 GHz to 20 GHz has been identified as a suitable candidate for short-haul line-of sight (LOS) links. As a consequence, a 6.73 km terrestrial LOS link centered at 19.5 GHz was recently established between the How...

This paper points out that the fundamental partial differential equation (PDE) implies that the drifts of the underlying processes are irrelevant, regardless whether the state factors are tradable or not. Since the simple boundary condition for default-free discount bonds can be satisfied by a linear discount function, the variances and covariances of the underlying processes are also irrelevan...

Today’s models for propagation-based constraint solvers require propagators as implementations of constraints to be at least contracting and monotonic. These models do not comply with reality: today’s constraint programming systems actually use non-monotonic propagators. This paper introduces the first realistic model of constraint propagation by assuming a propagator to be weakly monotonic (co...

<p style='text-indent:20px;'>The notion of propagation chaos for large systems interacting particles originates in statistical physics and has recently become a central many areas applied mathematics. The present review describes old new methods as well several important results the field. models considered include McKean-Vlasov diffusion, mean-field jump Boltzmann models. first part this...
