In this technical report, we provide an analysis on the image formulation of structured light based techniques in the presence of strong ambient illumination. In Section 1, we derive an analytical expression for the signal-noise-ratio (SNR) of structured light coding schemes. We show that the SNR is proportional to the power ratio between structured light signal and ambient illumination. In Sec...

We study the resummation of singular distributions for electroweakboson production at large transverse momentum in hadronic collisions. We describe the factorization properties of the cross section near partonic threshold and construct the resummed cross section at next-toleading logarithmic accuracy in moment space in terms of soft gluon anomalous dimensions. We present full analytical results...

QED radiative corrections to the cross section of diffractive electro-and photoproduction of vector mesons is calculated at HERA energies. Both semi-analytical and Monte Carlo approaches are discussed and compared.

To offload our manuscript we have placed a portion of our work here. In Section 1 we derive analytical closedform expressions for the (w)CBC metric variation in regular topologies while next, we draw insights regarding the cDSMA performance from the degree distributions of the studied ISP topologies. Section 3 presents the way the cDSMA practical implementation operates under multipath routing ...

We give a classical geometric optics description of incoherent solitons—those launched by a diffuse source. This method is intuitive, advances predictions such as the existence of solitons of arbitrary cross section, and importantly, it provides a simple (universal) analytical description for the incoherent solitons of any nonlinear medium. Previously, analytical results were known for the ln I...

section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...

The modern public administration as one of the reforming strategies in government section, provides the governments with several solutions. Since, this strategy is considered as a keystone for administrative reforms in Iran, hence the study on its consequences is urgent. Having a review on the theoretical bases of modern public administration and Iran's experiences on that, in this article an a...

Introduction: Due to increasing cesarean section rate in recent decades among pregnant women and the effect of maternal desire to do delivery type and the importance of self-efficacy in the choice of delivery methods and overcome the fear of childbirth. Determine the self efficacy rate in pregnant women during the pregnancy is required. Research showed that mothers with Low self-efficacy, thin...
