Paralleling Dissimilar Generators: Part 2 – Compatible Alternators
Paralleled alternators are compatible if they can operate in parallel without having damaging or disruptive neutral currents flowing between them. The magnitude of neutral current flow related to the dissimilarity between paralleled sets depends upon the shape of their voltage waveforms. Depending on the generators’ temperature rise characteristics, age and insulating ratings, neutral current f...
متن کاملStormram 2: A MRI-Compatible Robotic System for Breast Biopsy
In breast cancer screening, the doctor looks for lesions using mammography, ultrasound, palpation and/or MRI. A suspicious lesion may need to be biopsied; if the lesion is only visible on MRI, then a MRI-guided biopsy is required which is a long and costly procedure. Also, because manual needle insertion takes place outside the scanner, there is no real-time imaging feedback resulting in insert...
متن کاملCompatible and almost compatible pseudo-Riemannian metrics
In this paper, notions of compatible and almost compatible Riemannian and pseudo-Riemannian metrics, which are motivated by the theory of compatible (local and nonlocal) Poisson structures of hydrodynamic type and generalize the notion of flat pencil of metrics (this notion plays an important role in the theory of integrable systems of hydrodynamic type and the Dubrovin theory of Frobenius mani...
متن کاملCompatible Trees ∗
Two plane geometric graphs are said to be compatible when their union is a plane geometric graph. Let S be a set of n points in the Euclidean plane in general position and let T be any given plane geometric tree whose vertex set is S. The main problem we consider in this work consists of finding a second plane geometric tree T ′ on S, such that T ′ is compatible with T and shares with T a minim...
متن کاملCommon fixed point theorems for compatible and weakly compatible mappings
Results on common fixed points for pairs of single and multivalued mappings on a complete metric space are examined. Our work establishes a common fixed point theorem for a pair of generalized contraction self-maps and a pair of set-valued mappings.
