Correlation feature and instance weights transfer learning for cross project software defect prediction
Published 2021-02-01“…In our method, a local data gravitation between source and target domains determines instance weight, while features that are highly correlated with the learning task, uncorrelated with other features and minimizing the difference between the domains are rewarded with a higher feature weight. …”

Analysis of the vacuum solution of the five-dimensional Einstein field equations with negative cosmological constant via variational symmetries
Published 2025-02-01“…The Kaluza-Klein theory can be reckoned as a classical unified field theory of two of the significant forces of nature gravitation and electromagnetism. This formulation geometrically demonstrates the effects of a gravitational and an electromagnetic field by investigating a five-dimensional space with a metric constructed via the spacetime metric and the four-potential of the electromagnetic field. …”

The importance of transportation networks and urban services in assessing the functional balance of human settlements: The case of the Makkah region in Saudi Arabia
Published 2025-01-01“…Our investigation highlights the limitations of the region’s urban structure and suggests solutions for addressing their root causes by comparing the current state of the region’s population, which houses 132 urban centers, and an alternative model based on a gravitational urban law utilizing Reilly’s law of retail gravitation (1931), which manipulates data relevant to population and transportation networks. …”

Imagined Libya: geopolitics of the margins
Published 2022-12-01“…The subsequent sections analyze geopolitical discourses from different sources to offer a review of some important spatial imaginaries that have contributed to representing, constituting and apprehending Libya as a subject and an object of international politics: ancient geography’s environmentalism; Italy’s imperial colonialism; Gaddafi’s pan-Arabism and, later, pan-Africanism; and Turkey’s pan-Ottomanism.Before modern colonisation, the imaginary of (today’s) Libyan territory was long apprehended through the dichotomy between urban (hadari) and rural (badawi) spaces, with the political and normative centre of gravitation oscillating from the former (during the Arab and later Ottoman hegemony) to the latter (during the rise of the Sanussi order). …”

Evolution paths of urban forms influenced by landforms: Asynchrony but convergence
Published 2025-01-01“…Current dynamic indices often overlook the global physical gravitation and the interactions between new and old urban patches, leading to errors in assessing their agglomeration effects. …”
