Industry standards for shielded medium-voltage cables (5–46 kV) have recently been revised, changing the dc test voltages for field tests and test durations and limiting tests to newly installed cables. The following industry groups’ specifications and standards provide different guidelines for dc field tests for cross-linked polyethylene and ethylene propylene rubber insulated cables: IEEE, In...

Shielded coherent synchrotron radiation is discussed for two cases: (1) a beam following a circular path midway between two parallel conducting plates, and (2) a b earn circulating in a toroidal chamber. Wake -fields and the energy radiated are computed for both cases. Under conditions like those of the high-energy bunch compressor of the Next Linear Collider (NLC), in which bunches as short as...

INTRODUCTION Microstrip transceiver arrays have been demonstrated to provide higher efficiency on signal excitation/reception and low mutual coupling and have become a popular RF solution to parallel MR imaging at ultrahigh fields in humans [1,2]. In most designs, the ground planes of microstrips are separated (Fig 1) to minimize their mutual coupling [1-5]. Practically, due to space limitation...

Cloud computing o‚ers the economies of scale for computational resources with the ease of management, elasticity, and fault tolerance. To take advantage of these bene€ts, many enterprises are contemplating to outsource the middlebox processing services in the cloud. However, middleboxes that process con€dential and private data cannot be securely deployed in the untrusted environment of the (ed...

The electromagnetic (EM) properties of shielded gyromagnetic spheres are characterized with the aid an electrodynamic model formulated for transverse electric (TE) modes isotropic sphere, in a similar way as dielectric resonators commonly analyzed. Broadband characteristics geometric and energy filling factors presented. A new measure magnetic loss tangent is introduced which positive despite i...

Noise mapping of urban areas according to standardized engineering calculation methods systematically results in an underestimation of noise levels at areas shielded from direct exposure to noise, such as inner yards. In these methods, road traffic lanes are represented by point sources and noise levels are computed utilizing point-to-point propagation paths. For a better prediction of noise le...
