Later, cable theory with its mathematical derivatives allowed ever more sophisticated neuron models to be explored by workers such as Jack, Rall, Redman, Rinzel, Idan Segev, Tuckwell, Bell, and Iannella. More recently, cable theory has been applied to model electrical activity in bundled neurons in the white matter of the brain. [1]
The magnetic field inside a coaxial cable can be divided into three regions, each of which will therefore contribute to the electrical inductance seen by a length of cable. [ 11 ] The inductance L cen {\displaystyle L_{\text{cen}}\,} is associated with the magnetic field in the region with radius r < a {\displaystyle r<a\,} , the region inside ...
The Journal of Healthcare Management is a bimonthly peer-reviewed academic journal covering management in health care. It is published by Lippincott Williams & Wilkins on behalf of the American College of Healthcare Executives. [1] Each issue prints an interview with a leading healthcare executive.
The above cable equation is valid for a single cylindrical cable. Linear cable theory describes the dendritic arbor of a neuron as a cylindrical structure undergoing a regular pattern of bifurcation, like branches in a tree. For a single cylinder or an entire tree, the static input conductance at the base (where the tree meets the cell body or ...
While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains an observable phenomenon in natural terms. [127] [128] "Scientific fact and theory are not categorically separable", [129] and evolution is a theory in the same sense as germ theory or the theory of gravitation. [130]
Since the eddy currents are generated by an AC magnetic field, their penetration into the subsurface region of the material is limited by the skin effect. The applicability of the traditional version of eddy current testing is therefore limited to the analysis of the immediate vicinity of the surface of a material, usually of the order of one ...
In model-based FDI techniques some model of the system is used to decide about the occurrence of fault. The system model may be mathematical or knowledge based. Some of the model-based FDI techniques include [2] observer-based approach, parity-space approach, and parameter identification based methods. There is another trend of model-based FDI ...
High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.
