Permit-to-work ( PTW) refers to a management system procedure used to ensure that work is done safely and efficiently. It is used in hazardous industries, such as process and nuclear plants, usually in connection with maintenance work. [ 1] It involves procedured request, review, authorization, documenting and, most importantly, de-conflicting ...
Integrated safe system of work. Integrated safe system of work ( ISSOW) is used in hazardous industry to request, review, approve and document tasks to be carried out by frontline workers. [1] It integrates permit-to-work, risk assessment and isolation management under a single electronic system, providing safety improvements to the user.
A connection form associates to each basis of a vector bundle a matrix of differential forms. The connection form is not tensorial because under a change of basis, the connection form transforms in a manner that involves the exterior derivative of the transition functions, in much the same way as the Christoffel symbols for the Levi-Civita ...
Chern–Weil homomorphism. In mathematics, the Chern–Weil homomorphism is a basic construction in Chern–Weil theory that computes topological invariants of vector bundles and principal bundles on a smooth manifold M in terms of connections and curvature representing classes in the de Rham cohomology rings of M. That is, the theory forms a ...

Connection (principal bundle) In mathematics, and especially differential geometry and gauge theory, a connection is a device that defines a notion of parallel transport on the bundle; that is, a way to "connect" or identify fibers over nearby points. A principal G-connection on a principal G-bundle over a smooth manifold is a particular type ...
Jhat Pat, also spelled as Jhatpat, Dera Allah Yar is a sub-division of Jaffarabad District of Balochistan province, Pakistan. [1] Jhat Pat ( Urdu: جہٹ پٹ) district lies southeast of the Pakistani province of Balochistan. The Jaffarabad District headquarters are located at Dera Allah Yar formerly and still known as Jhatpat among locals. [2]
Federal funding will probably play a key role in making hyperloops happen, particularly since some of the mooted projects cross state lines. One proposed hyperloop that’d link Chicago, Cleveland ...
