Although in the design of transmit RF coils, B(1) homogeneity is crucial for good image quality, discussion of electric field (E-field) distribution in the literature has been mostly limited to specific absorption rate (SAR) and patient loading (dielectric) effects. In this work, we report on a different aspect of E-field: the receive-only surface coil heating resulting from the voltage drop ac...

This paper addresses subsea electric cable routing using the application of decision support systems combined with experts’ knowledge. The methodology is successfully applied to a case study on Spanish coast. ranking method calculates multiple criteria weights, and weighted product determines most suitable space. environmental criteria, weight 61.4%, exceed significance other essential in based...

in this paper, a new approach to modify cable tension measuring mechanism is described; furthermore, the constructed boards which amplify load cell output are introduced. this approach has some advantages including of providing feedback for motors, evaluating the robot’s ultimate load carrying capacity, improving the motor control system and estimating the vibrating deflections of the end effec...

High voltage (HV) cables are widely used in the transmission and distribution of electrical energy. The design manufacture these with great precision importance for power systems. Mistakes made during manufacturing phase defects that may occur structure cable material can cause premature aging continuous malfunctions cables. Factors such as air gaps, foreign substances, moisture insulating punc...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

in this paper robust pid control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. in dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. to develop the idea of control for cable robots with elastic cables, a robust pid control for cable driven robots with ideal rigid cables is firstly de...

Transformer together with its windings is a complex oscillatory system. The interaction between the transformer and an electric network during transients can cause development of resonance phenomenon in leading to overvoltages risk fault. This report presents results studies phenomena windings, caused by containing feeder cable. approach simple assessment dominant oscillation frequency voltage ...

The relation between the fine structure, electric field equations, and electric circuit models of skeletal muscle fibers is discussed. Experimental evidence illustrates the profound variation of potential with circumferential position, even at low frequencies (100 Hz). Since one-dimensional cable theory cannot account for such variation, three-dimensional cable theory must be used. Several circ...

This work reports the results of the theoretical investigation of nonlinear dynamics and spiral wave breakup in a generalized two-variable model of cardiac action potential accounting for thermo-electric coupling and diffusion nonlinearities. As customary in excitable media, the common Q10 and Moore factors are used to describe thermo-electric feedback in a 10° range. Motivated by the porous na...
