In this article, the radar cross-section of a parallel-fed dipole array placed over a conducting cylinder is determined analytically. The Euler rotation method is employed to extract the angular position of antenna elements over the cylindrical surface. The array radar cross-section is calculated ...
FIG. 4 shows a cross section of the shaft portion; FIGS. 5, 5a and 5b are, respectively, a front view and a side view of parts of a cylinder seen in FIG. 1; FIGS. 6, 6a and 6b are, respectively, front view and a side view of parts of slide pawls seen in FIG. 1; ...
In order to check the validity of this technique, the radar cross-section of a single coated cylinder, a linear array of cylinders, and an arbitrary position array of cylinders are calculated and compared with available data in the literature. Furthermore, the near field is calculated to prove...
the external gear has at one end grooves of triangular cross-section which define four control orifices of the first set and co-operate with ten control orifices of the second set which are alternately connected to the pressure and vacuum sides and are disposed in an adjoining and wall connecte...

The present invention relates to a clamp crow (10) for attachment to a slide rail (100) of an operating table, the slide rail (100) having a rectangular cross section. Clamp crow (10) comprises a main part (12) having at least one suppor... カッツェンシュタイン,ベルンハルト 被...
To allow a variety of cylinder representations in the application this geometry allows a flexible way of specifying the data of offsets for start position, end position and radius within a data array. All parameters are listed in the table below. Parameters defining a cylinders geometry. ...
A previously developed theory of the capillary rise between two closely spaced cylinders has been extended to systems of three and four equidistant cylinders as a function of the distance of separation and the contact angle. The multicylinder system has also been treated. At small separations betwee...
The cylinder also provides for inputs at the top and outputs at the bottom. Cylindrical structures are highly modular because it is possible to increase the diameter of the ring and the height of the cylinder. Figure 22. Ring Architecture 'C40–8 'C40–1 'C40–2 'C40–7 'C40–3 'C40...
A Weierstrass condition is illustrated for a circular structure (i.e., a cross section through a cylinder or sphere) having a surface of radius R and a concentric notional circle having a radius R/n, where n is the refractive index of the structure. Any light ray that passes through the...
