The drift angle caused by the Earth’s self-rotation may introduce rotational displacement artifact on the geolocation results of imagery acquired by an Earth observing sensor onboard the International Space Station (ISS). If uncorrected, it would cause a gradual degradation of positional accuracy from the center towards the edges of an image. One correction method to account for the drift angle...

Abstract We present an analytical approach to construct the Lie algebra of finite-dimensional subsystems driven asymmetric top rotor. Each rotational level is degenerate due isotropy space, and degeneracy increases with excitation. For a given excitation, we determine nested commutators between drift drive Hamiltonians using graph representation. then generate for arbitrary excitation inductive...

Diffusion and drift of a graphene flake on a graphite surface are analyzed. A potential energy relief of the graphene flake is computed using ab initio and empirical calculations. Based on the analysis of this relief, different mechanisms of diffusion and drift of the graphene flake on the graphite surface are considered. A new mechanism of diffusion and drift of the flake is proposed. Accordin...

The general ring laser operation model is adopted for the large gyroscopes C-II and G. An extended set of auxiliary sensors information is used for the long time period data modeling and ring laser behavior analysis with respect to the ideal case. Both instrumental errors and orientational effects are estimated and compensated where possible. The instrumental stability improved approximately fo...

introduction: wind erosion is one of the most important factors in desert environments. prevailing winds can shift sand dunes and affect their accumulation and morphology. also, wind regime determines the direction of sand dune mobility in different ways. therefore, the wind regime, frequency, direction and velocity are supposed to be the most important factors to form the morphology of sand du...

a total of 2519 blood samples were collected from five distinct populations of larestan, in fars province, in iran (lar, gerash, khour, latifi and berake) were examined for abo and rh blood groups. the gene frequencies obtained from these samples were compared with the hitherto reported corresponding data from other populations of fars province to determine the genetic structure of the larestan...

In protoplanetary discs, the coagulation of dust grains into large aggregates still remains poorly understood. Grain porosity appears to be a promising solution allow survive and form planetesimals. Furthermore, shattering has generally been considered come only from collisional fragmentation; however, new process was recently introduced, rotational disruption. We wrote one-dimensional code tha...

The streaming instability is one of the most promising pathways to formation planetesimals from pebbles. Understanding how this operates under realistic conditions expected in protoplanetary disks therefore crucial assess efficiency planet formation. Contemporary models show that magnetic fields are key driving gas accretion through large-scale, laminar stresses. However, effect such on has not...

The paper presents an analysis of the quality of motion data from an iPod Touch (4th gen.). Acceleration and orientation data derived from internal sensors of an iPod is compared to data from a high end optical infrared marker-based motion capture system (Qualisys) in terms of latency, jitter, accuracy and precision. We identify some rotational drift in the iPod, and some time lag between the t...
