The real roots of the characteristic polynomial of a planar linkage determine its assembly modes. In this work it is shown how the characteristic polynomial of a Baranov truss derived using a distance-base formulation contains all the necessary and sufficient information for solving the position analysis of the Assur kinematic chains resulting from replacing some of its revolute joints by slide...

measurements of the tilt angle of potential fields can be a useful aid to their interpretation. there are several varieties of the methods in use, such as tilt angle, and the derivative of tilt angle. tilt angle filters are used for exact edge detection of the rectangular bodies artificially by writing a matlab code. the gravity effects of these models are computed by standard algorithms. the e...

in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...

We give a characterization of complete interpolating sequences for the Fock spaces $\mathcal{F}^p_\varphi,\ 1\leq p<\infty$, where $\varphi(z)=\alpha\left(\log^+|z|\right)^2,\ \alpha>0$. Our results are {analogous} to classical Kadets-Ingham's $1/4-$Theorem on perturbation Riesz bases complex exponentials, and they answer question asked by A. Baranov, Dumont, Hartmann K. Kellay in \cite[page 31...

The genus Troglocladius Andersen, Baranov et Hagenlund, gen. n. is erected based on T. hajdi Andersen, Baranov et Hagenlund, sp. n. collected at 980 m depth in the Lukina jama-Trojama cave system in Croatia. Morphological features such as pale color, strongly reduced eyes and very long legs make it a typical cave animal. Surprisingly, it has also retained large wings and appears to be capable o...

the objective of this paper is to explore the effect of financial crisis on trade flows of steel industries in the major asian-pacific steel producing countries. using a static and dynamic panel data analysis, we test the hypothesis that the global financial crisis has a negative effect on asia-pacific bilateral steel trade flows. we also examine the role of regional trade integration in bilate...

one of the most valuable and important application of artificial satellites in geodetic sciences is recovery of the earth&apos;s gravity field. orbits of satellites either gravimetric or nongravimetric are analyzed to improve the earth&apos;s gravity field. gravimetric satellites are launched at low altitudes to observe gravity field in more detail. grace twin satellites are the second spacecra...
