This invention applies to more accurate determination of the displacement of merchant ships built from elastic materials, which suffers from significant temporary or permanent longitudinal deflections in ship's service due to hull bending, such as hull sagging or hogging, what provokes changes of the immersed hull form, leading to inaccuracies in 10 determination of the ship's displacement, par...

Subject of this paper is the comparison of the results obtained exploiting the Permanent Scatterers (PS) Technique on ERS DInSAR data with displacement measurements carried out by means of optical leveling and GPS.

Accidental displacement of the third molar tooth or its fragment into the anatomical spaces is a rare but potentially serious complication. The most common sites of mandibular third molar displacement are the sublingual, submandibular, and pterygomandibular spaces. Removal of a displaced tooth or its fragments from these spaces may be difficult due to poor access and the vital structures involv...

In this study of the behavior for large times of a class of elasticplastic oscillators under conservative loading, conditions on the relative stiffness of the oscillator and the loading agent are given that guarantee that permanent displacements arising during a motion automatically are removed in the limit of large times. When these conditions are not met, a sharp bound independent of initial ...

Introduction: Permanent first molar is the most important unit in the chewing system. Ear-ly loss of first molars can significantly reduce chewing efficiency, increase overbite, lead to premature eruption of the permanent second and third molars, and displacement of adjacent teeth. The purpose of this study was to determine the associated factors of permanent first molar caries in 7-9 years old...

This paper presents the design and realization of a three degrees of freedom (DOFs) displacement measurement system composed of Hall sensors, which is built for the XYθz displacement measurement of the short stroke stage of the reticle stage of lithography. The measurement system consists of three pairs of permanent magnets mounted on the same plane on the short stroke stage along the Y, Y, X d...

Crown dilaceration of permanent teeth occurs due to the non-axial displacement of the already formed hard tissue portion of the developing crown at an angle to their longitudinal axis due to trauma to the primary predecessors. This is a rare condition, representing only 3% of the total of injuries to developing teeth and usually occurs in permanent maxillary incisors because of the close proxim...

background : limited studies are available on the calculation of radiation exposure and its associated risks for people in contact with patients who have been treated with permanent prostate brachytherapy. in this study the changes in the radiation exposure were calculated in different stages of the bladder fullness in prostate seed brachytherapy. methods :magnetic resonance images of three pat...
