In recent years, modified theories of gravity have been extensively studied because of the discovery and confirmation of the current phase of accelerated expansion of the universe. The f(R,T) theory of gravity is one such theory, proposed by Harko et al. ... see more

The length of the gravitational field lines/of the orthogonal trajectories of a family of gravity equipotential surfaces/of the plumbline between a terrestrial topographic point and a point on a reference equipotential surface like the geoid í also known ... see more

This paper introduces GRACETOOLS, the first open source gravity field recovery tool using GRACE type satellite observations. Our aim is to initiate an open source GRACE data analysis platform, where the existing algorithms and codes for working with GRACE... see more

Recently the so-called mimetic gravity approach has been used to obtain corrections to the Friedmann equation of General Relativity similar to the ones present in loop quantum cosmology. In this paper, we propose an alternative way to derive this modified... see more

This paper estimates econometrically the impact of NAFTA on US-Mexico and US-third countries (groups of countries) trade flows. Using a traditional gravity- equation framework, we try to see to what extent the bilateral trade flows between the US and diff... see more

The present study addresses the effects of lateral center-of-gravity (CG) movement, resulting from asymmetric firing of some of the onboard stores, on the dynamics and control of a combat aircraft while attempting the highly demanding Herbst manoeuver. Th... see more

The phenomenon of transient flows in charge is sometimes accompanied by excessive pressure and can cause huge damage to pipes and hydraulic devices. These flows have been for several years of relatively advanced investigations. However, given the vast are... see more

With the rise of anti-free-trade sentiment on both sides of the Atlantic, there is a growing urgency by trade negotiators to conclude the Trans-Atlantic Trade and Investment Partnership (TTIP) negotiations. The harmonisation of non-tariff restrictions is ... see more

To estimate correctly the effect of variable trade costs on firms' exports, the gravity equation should control for the number of firms that participate in foreign markets. Due to the absence of these data, previous studies control for this omitted variab... see more
