The surficial sediments recovered from 12 sites located near the channel axis of the Florida Straits and the lower slope off NW Cuba were analyzed for total organic carbon (TOC), nitrogen (TN), phosphorus (TP), elemental C:N:P ratios, C and N isotopic values, and 14C dating. The depth profiles of TOC, TN, and TP (0-18 cm) displayed a downcore trend and a significant variation. The TOC values we...

Errors compensation of micromachined-inertial-measurement-units (MIMU) is essential in practical applications. This paper presents a new compensation method using a neural-network-based identification for MIMU, which capably solves the universal problems of cross-coupling, misalignment, eccentricity, and other deterministic errors existing in a three-dimensional integrated system. Using a neura...

An axis-parallel d–dimensional box is a Cartesian product R1 × R2 × · · · × Rd where Ri (for 1 ≤ i ≤ d) is a closed interval of the form [ai, bi] on the real line. For a graph G, its boxicity box(G) is the minimum dimension d, such that G is representable as the intersection graph of (axis–parallel) boxes in d–dimensional space. The concept of boxicity finds applications in various areas such a...

We present the design and fabrication of a single axis low noise accelerometer in an unmodified commercial MicroElectroMechanical Systems (MEMS) process. The new microfabrication process, MEMS Integrated Design for Inertial Sensors (MIDIS), introduced by Teledyne DALSA Inc. allows wafer level vacuum encapsulation at 10 milliTorr which provides a high Quality factor and reduces noise interferenc...

The present work investigates the combined effect of angle attack ( AOA) (the between semi-major axis cylinder and vertical axis), gap ratio G/ D (where G represents distance center moving wall denotes elliptic cylinder) on flow around an near a wall. Here, AOA covers [Formula: see text], text] with ranging from 0.6 to 2.5. Reynolds number (based free-stream velocity axis) is fixed 150. resulti...

The title compound, C16H16N2S2, adopts a gauche (+)-gauche (+)-gauche (+) (g(+)g(+)g(+) ) conformation in the NH-CH2-CH2-NH bond sequence. In the crystal, mol-ecules are connected by pairs of N-H⋯S=C hydrogen bonds and C-H⋯π inter-actions, forming a tape structure along the c-axis direction.

Scott Hogg & Associates Ltd. have completed the development of a 3-axis, helicopter towed, aeromagnetic gradiometer. The towed bird is a complete airborne system with 4 cesium sensors, radar altimeter, pitch, roll and yaw measurement, a 3-axis magnetic fluxgate and a GPS positioning system. The system is designed to provide accurate geo-referenced magnetic gradients; G-east, G-north and Gvertic...

Let F and G denote two closed convex curves in the (X, Z)-plane and in the (Y, Z)-plane, correspondingly, that are symmetric about the Z-axis and cross at two points. Let S denote the solid that results from wrapping (X, Y )parallel ellipses around F and G. Surprisingly, S need not be convex (though all intersections with planes containing the Z-axis are!). We analyze under which condition the ...

We describe a method for finding the families of relative equilibria of molecules which bifurcate from an equilibrium point as the angular momentum is increased from 0. Relative equilibria are steady rotations about a stationary axis during which the shape of the molecule remains constant. We show that the bifurcating families correspond bijectively to the critical points of a function h on the...

Rotational behavior inducing triaxiality is discussed for Cr in the cranked NilssonStrutinsky (CNS) model, as well as in the spherical shell model. It is shown that the low-spin region up to about I=8, has a prolate well-deformed shape. At higher spins the shape is triaxial with a “negative-γ” deformation, that is, with rotation around the classically forbidden intermediate axis. By comparing c...
