The solvability and subellipticity of systems of pseudodifferential operators
The paper studies the local solvability and subellipticity for square systems of principal type. These are the systems for which the principal symbol vanishes of first order on its kernel. For systems of principal type having constant characteristics, local solvability is equivalent to condition (Ψ) on the eigenvalues. This is a condition on the sign changes of the imaginary part along the oriente

On- and Off-Shore Prepositioning and Delivery Mechanism for Humanitarian Relief Operations
Traditionally, international humanitarian organisations have used on-demand dispatch of disaster relief goods from regional logistics units (RLUs) for sudden onset disaster response. This paper investigates the improvements in efficiency and resilience of disaster relief operations by combining the existing method of onshore prepositioning of relief items in RLUs with offshore prepositioning of re
Spatiotemporal flame mapping in a large-bore marine diesel engine using multiple high-speed cameras
A calibrated multiple high-speed camera arrangement recording the flame emission from three different directions has been demonstrated on an engine. From the multiple views, the flame position inside the engine cylinder can be spatially mapped, allowing quantitative studies of the dynamics of ignition, flame development and propagation. Through space carving, the three-dimensional flame contour ca

ULTRA CARRIER SYSTEM (UCS) - A NEW CONCEPT FOR SHORT SEA TRANSPORT.
e\vec{p}->ep\pi^0 rection studied in the \Delta(1232) mass region using polarization asymmetries
Measurements of the angular distributions of target and double-spin asymmetries for the Δ+(1232) in the exclusive channel →p(→e,e′p)π0 obtained at the Jefferson Lab in the Q2 range from 0.5 to 1.5GeV2/c2 are presented. Results of the asymmetries are compared with the unitary isobar model [D. Drechsel et al., Nucl. Phys. A645, 145 (1999)], dynamical models [T. Sato and T. S. Lee, Phys. Rev. C 54, 2
