We compared two methods of 3D digital subtraction angiography (DSA)--propeller and standard rotation--for the assessment of aneurysmal morphology and its relation to neighboring vessels. Aneurysms were correctly visualized and localized with both techniques. 3D DSA with propeller rotation technique seems to be effective and allows us to reduce the amount of contrast material related to a shorte...

This study is to investigate propulsion efficiency due changes in draught of ship using data series and theoretical approach. A hard chain rescue boat with triplet screw was used for the examine effect thrust deduction factor wake fraction its relevance by observing hull propeller interaction based on openwater test Wageningen Data Series cavitations analysis has been neglected. The done hydrod...

The coframe (teleparallel) description of gravity is known as a viable alternative to GR. One of advantages of this model is the existence of a conserved energy-momentum current witch is covariant under all symmetries of the threeparameter Lagrangian. In this paper we study the relation between the covector valued current and the energy-momentum tensor. Algebraic properties of the conserved cur...

A new method for computing all elements of the lattice quark propagator is proposed. The method combines the spectral decomposition of the propagator, computing the lowest eigenmodes exactly, with noisy estimators which are ‘diluted’, i.e. taken to have support only on a subset of time, space, spin or colour. We find that the errors are dramatically reduced compared to traditional noisy estimat...

The efficient representation and manipulation of time information is key to any successful implementation of a verification tool. We extend the syntax and semantics of the higher level specification language Promela to include constructs and statements based on the model of timed Bfichi automata [2]. We implement these extensions on top of the verification tool Spin.

WMSSM = h u ijQi ·HiUj + hijQi ·HdD̄j + hijLi ·HdĒj + μHu ·Hd. (1) (1) has been constructed so as to conserve R-parity (even for particles, odd for sparticles) Rp ≡ (−1), B, L and s being baryon no., lepton no. and spin. This is equivalent to the conservation of matter parity which transforms the superfields as (Li, Ēi, Qi, Ūi, D̄i) → −(Li, Ēi, Qi, Ūi, D̄i), (Hu, Hd, Vγ, VZ , V + W , V − W ) → (Hu...

In propeller driven aircraft the main source for internal noise are almost tonal disturbances caused by the propeller blades that are passing the fuselage. In a certain four propeller military transport aircraft the maximum sound level in the cabin can reach up to 110 dB(A), not taking into account any noise control treatments. Inside the semi closed loadmaster working station (LMWS) the sound ...
