IDENTIFICATION OF POTENTIAL SITES FOR WATER HARVESTING STRUCTURES USING GEOSPATIAL TECHNIQUES AND MULTI-CRITERIA DECISION ANALYSIS
Water harvesting structures Remote sensing and GIS Watershed management MSE AHP
2019/2/27
Changing hydrological phenomenon and increase the water demand in all sectors create a huge problem of water scarcity. Precipitation is one and only major source to mitigate this problem. In Central I...
Rational permeability coefficient of a permeable lining for composite tunnel lining structures
tunneling engineering deeply-buried tunnel composite lining structure concrete permeable lining grouting circle parameter permeability coefficient reasonable value
2018/5/11
Various factors influence the tunneling are simplified considering the axial symmetry of the composite lining structure. The analytical expressions for the seepage field，stress，and displacement in the...
3D DOCUMENTATION AND BIM MODELING OF CULTURAL HERITAGE STRUCTURES USING UAVS: THE CASE OF THE FOINIKARIA CHURCH
3D models BIM cultural heritage documentation
2016/10/14
The documentation of architectural cultural heritage sites has traditionally been expensive and labor-intensive. New innovative technologies, such as Unmanned Aerial Vehicles (UAVs), provide an afford...
Electrostatic and Conformational Effects on the Electronic Structures of Distortional Isomers of a Mixed-Valence Binuclear Cu Complex
Electrostatic Conformational Electronic Structures Distortional Isomers Mixed-Valence Binuclear Cu Complex
2016/5/23
The electronic structure of the binuclear copper complex [Cu(2)(L)](3+) [L = N(CH(2)CH(2)N(H)CH(2)CH(2)N(H)CH(2)CH(2))(3)N] has been investigated by resonance Raman and electroabsorption spectroscopy....
Crystal structures of a group II chaperonin reveal the open and closed states associated with the protein folding cycle
Crystal structures group II chaperonin reveal closed states associated protein folding cycle
2015/12/11
Chaperonins are large protein complexes consisting of two stacked multisubunit rings, which open and close in an ATP-dependent manner to create a protected environment for protein folding. Here, we de...
ESSENTIAL KILLING FIELDS OF PARABOLIC GEOMETRIES: PROJECTIVE AND CONFORMAL STRUCTURES
PARABOLIC GEOMETRIES PROJECTIVE
2015/10/14
We use the general theory developed in our article [1]
in the setting of parabolic geometries to reprove known results on
special in nitesimal automorphisms of projective and conformal
geometries.
Seismic transmission tomography: determination of the elastic properties of building structures (some examples)
applied geophysics cultural heritage inversion seismic tomography
2015/9/29
This paper is a general review on seismic transmission tomography considering data acquisition and processing. Some questions on linear and non linear inversions are tackled, and advice given on the c...
In the late 1980’s Hitchin [51] and Simpson [71] discovered deep connections
between representations of fundamental groups of surfaces and algebraic geometry.

T. The deformation space t(E) of convex Rp2_ structures on a closed
surface Y with X(z) < 0 is closed in the space Hom(7r, SL(3, IR))/SL(3, IR)
of equivalence classes of representations r1 (l) -- ...

The purpose of this paper is to investigate convex real projective structures on compact surfaces. Let RP2
be the real projective plane and
PGL(3, R) the group of projective transformations RP2

Compression schemes, stable definable families, and o-minimal structures
Compression schemes stable definable families o-minimal structures
2015/9/28
We show that any family of sets uniformly definable in an ominimal
structure has an extended compression scheme of size equal
to the number of parameters in the defining formula.
Evidence of Apulian crustal structures related to low energy seismicity (Murge - Southern Italy)
Bouguer anomalies Murgian plateu low energy seismicity tensional structures
2015/9/28
The discovery of recent co-seismic sedimentary structures and the detection of low energy seismic activity in the Murgian plateau (Apulia - Southern Italy) motivated a more detailed examination of the...

Mutually algebraic structures and `automatic' quantifier elimination.
Characterizing model completeness among mutually algebraic structures
algebraic structures model completeness
2015/9/28
We characterize when the elementary diagram of a mutually algebraic
structure has a model complete theory, and give an explicit
description of a set of existential formulas to which every formula
i...
Mutually algebraic structures and expansions by predicates
algebraic structures predicates
2015/9/28
We introduce the notions of a mutually algebraic structures and
theories and prove many equivalents. A theory T is mutually algebraic
if and only if it is weakly minimal and trivial if and only if n...
