A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)

Archaeological Prospection, EarlyView.
ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...

Geodesics and geodesic deviation for impulsive gravitational waves [PDF]

Journal of Mathematical Physics, 1998
The geometry of impulsive pp-waves is explored via the analysis of the geodesic and geodesic deviation equation using the distributional form of the metric. The geodesic equation involves formally ill-defined products of distributions due to the nonlinearity of the equations and the presence of the Dirac δ-distribution in the space–time metric.

Geophysical Investigations at the Artemision at Amarynthos of Euboea (Greece)

Archaeological Prospection, EarlyView.
ABSTRACT A combination of resistivity mapping and three‐dimensional electrical resistivity tomography (ERT) was used to investigate the subsurface of the sanctuary of Artemis Amarysia in Amarynthos, Euboea (Greece), an area where archaeological remains from the Bronze Age to the post‐Byzantine period are preserved.

Rigidity of Holomorphically Projective Mappings of Kähler Spaces with Finite Complete Geodesics

Mathematics
In this work, we consider holomorphically projective mappings of (pseudo-) Kähler spaces. We determine the conditions for finite complete geodesics that must be satisfied for the mappings to be trivial; i.e., these spaces are rigid.

Creating Brand Commitment and Brand Equity in International Food Companies Through Sustainability in European Countries

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the impact of corporate social responsibility (CSR) and customer brand equity (CBE) on brand commitment (BCO) towards a leading international food company, employing a cross‐cultural comparison between Spain and France. By addressing a key gap in the literature concerning the interactions between these constructs in the

A note on geodesic and almost geodesic mappings of homogeneous Riemannian manifolds [PDF]

Opuscula Mathematica, 2005
Let \(M\) be a differentiable manifold and denote by \(\nabla\) and \(\tilde{\nabla}\) two linear connections on \(M\). \(\nabla\) and \(\tilde{\nabla}\) are said to be geodesically equivalent if and only if they have the same geodesics.

The Impact of Knowledge Sharing Quality on Environmental Practices to Improve the Financial Performance of SMEs: The Mediating Role of Advanced Management Technologies

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how information quality influences the adoption of environmental practices in Mexican SMEs and how these practices affect financial performance, considering the mediating role of advanced management technologies. Knowledge exchange is assessed through training in knowledge management and internal knowledge transfer, both of

Geodesic motion near self-gravitating scalar field configurations

Discrete and Continuous Models and Applied Computational Science, 2019
We study the geodesics motion of neutral test particles in the static spherically symmetric spacetimes of black holes and naked singularities supported by a selfgravitating real scalar field.

On geodesics of phyllotaxis

Confluentes Mathematici, 2014
Seeds of sunflowers are often modelled by the map $n\longmapsto φ_θ(n)=\sqrt{n}e^{2iπnθ}$ leading to a roughly uniform repartition with two consecutive seeds separated by the divergence angle $2πθ$ for $θ$ the golden ratio. We associate to an arbitrary real divergence angle $2πθ$ a geodesic path $γ_θ: \mathbb R_{>0}\longrightarrow \mathrm{PSL}_2 ...

Experimental studies on multi‐scale data‐driven methods within the framework of structural health monitoring

Civil Engineering Design, EarlyView.
Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize
