This paper deals with a Maximum Likelihood (ML) shift estimation method in the context of High Resolution (HR) Polarimetric SAR (PolSAR) clutter. Texture modeling is exposed and the generalized ML texture tracking method is extended to the merging of various sensors. Some results on displacement estimation on the Argentière glacier in the Mont Blanc massif using dual-pol TerraSAR-X (TSX) and qu...

Les problèmes traités dans cette thèse relèvent du cadre général de la modélisation des tunnels profonds, en particulier dans les milieux viscoplastiques. L'objectif de notre travail est de combiner des travaux de recherche de type expérimental et numérique, pour aboutir à une modélisation correcte du problème de l'interaction massif-soutènement et pouvoir optimiser ainsi le dimensionnement des...

The study was conducted during 2020, at Fedis district of East Hararghe Zone, Oromia National Regional State; Ethiopia. Composting is a process where waste organic materials derived from plants and/or animals are decomposed by microbial action under aeration to produce friable homogenous product that added soil.

Abstract The underground construction is based on effective and rapid building of running tunnels that connect stations. most technique shield-driven tunneling. It the application a tunneling shield, it means, special aggregate excavates ground builds support. Even with fact holds surrounding massif, in weak layered rocks possible formation subsidence trough, namely, significant deformations da...

BACKGROUND Even though there is no consensus, many authors believe that in the cases of large hiatal defects, structurally altered crura and/or absence of peritoneal lining, a crural reinforcement should be performed. Reinforcement could be performed with different techniques and different type of mesh, either synthetic or biologic. The disadvantages of mesh repair include the possibility of se...

In Italy, use and production of asbestos asbestos-containing materials (ACMs) were banned in 1992, however, the risk exposure to still exists, because most ACMs are located industrial public buildings. A total 111 Italian buildings with friable non-friable surveyed; 500 air samples collected areas where contamination might have occurred. Airborne fiber concentration calculated from was averaged...

Integration of Apollo 17 field observations and photographs, sample investigations, Lunar Reconnaissance Orbiter Camera images, Chandrayaan-1 Moon Mineralogy Mapper (M 3 ) spectra, and Miniature Radio Frequency (Mini-RF) S-band radar images provides new insights into the geology of the valley of Taurus– Littrow on the Moon. Connecting the various remote observations to sample data enables a set...

Patients usually present with a solitary, polypoid, reddish, friable mass. The entire specimen is usually processed in order to rule out a concurrent cholesteatoma. Pathologic examination will reveal a granulation-type tissue with edematous stroma and a high density of capillaries (figure 1) associated with chronic inflammatory cells, including plasma cells, lymphocytes, histiocytes, and eosino...
