Dual polarization is becoming the standard for new weather radar systems. In contrast to conventional weather radars, where the reflectivity is measured in one polarization plane only, a dual polarization radar provides transmission in either horizontal, vertical, or both polarizations while receiving both the horizontal and vertical channels simultaneously. Since hydrometeors are often far fro...

Failure of the quay walls due to earthquakes results in severe economic loss. Because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. This study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

The adaptive plasticity of the spatial organization of the vestibuloocular reflex (VOR) has been investigated in intact and canal-plugged primates using 2-h exposure to conflicting visual (optokinetic, OKN) and vestibular rotational stimuli about mutually orthogonal axes (generating torsional VOR + vertical OKN, torsional VOR + horizontal OKN, vertical VOR + horizontal OKN, and horizontal VOR +...

Composition mechanisms are intended to build a target system out of many independent units. The paper presents how the aspect technology may leverage the hierarchical composition, by supporting two orthogonal mechanisms (vertical and horizontal) for composing completely autonomous parts. The vertical mechanism is in charge of coordinating heterogeneous components, tools or services at a high le...

based on the standards for design of structures, any structure should be designated for seismic loads and any combinations containing seismic loads. for spectral analysis of a structure, the site effect is taken into account by considering its effects on the design spectra. because of different lateral and vertical stiffness of the soil layers underneath the structure, the design spectra are di...

The writers of this paper see the current highway design standards as a two-dimensional projection which the horizontal and vertical alignments are treated separately. A model developed in this paper considers and study the sight distance as a three-dimensional alignment on the design requirements. The paper examines the required minimum radius of a horizontal curve combined with a crest or sag...

13 The South China Sea is a marginal basin with a complex circulation influenced by the 14 East Asian Monsoon, river discharge and intricate bathymetry. As a result, both the mesoscale 15 eddy field and the near-inertial energy distribution display large spatial variability and they 16 strongly influence the oceanic transport and mixing. 17 With an ensemble of numerical integrations using a reg...

on 11th of august 2012 the region was surprisingly struck by a shallow mw 6.4 (usgs) earthquake with pure right-lateral strike-slip character only about 50 km north of the north-tabriz fault. an east-west striking surface rupture of about 20 km length was observed in the field by geological survey of iran. only 11 minutes later and about 6 km further nw a second shallow event with mw 6.2 occurr...

We compared the spatial organization patterns of linear and angular vestibuloocular reflexes in frogs by recording the multiunit spike activity from cranial nerve branches innervating the lateral rectus, the inferior rectus, or the inferior obliquus eye muscles. Responses were evoked by linear horizontal and/or vertical accelerations on a sled or by angular accelerations about an earth-vertical...

Structural damage to r.c. buildings located in a near-fault area has been observed during strong ground motions, with long-duration horizontal pulses and high values of the ratio between the peak value of the vertical acceleration and the analogous value of the horizontal acceleration. The design provisions of current seismic codes are generally not very accurate for assessing the structural ef...
