Net Zero/Net Zero Carbon Emission

ADHYAYAN: A JOURNAL OF MANAGEMENT SCIENCES, 2023
Every other day we hear about environmental and climate issues and the effect of global warming or carbon emission. Many companies are shifting their concerns from making profits to making sustainable profits. The idea of saving the environment has propelled many start-ups also.

Towards Net Zero Railways for Net Zero Transport

As a low-friction transportation system, rail has some strong environmental credentials. However, it also has a reliance on some carbon-intensive technologies and materials that make a transition to net zero problematic. This chapter examines the prospects for net zero railways through the lens of Holden et al.’s (2020) nine grand narratives for ...

Transactions and Zero-Safe Nets

2001
When employing Petri nets to model distributed systems, one must be aware that the basic activities of each component can vary in duration and can involve smaller internal activities, i.e., that transitions are conceptually refined into transactions. We present an approach to the modeling of transactions based on zero-safe nets. They extend ordinary pt

Petri net processes for zero-safe nets

Fundam. Informaticae, 2005
Summary: Composition of modules to larger units is a technique frequently used during the software development life cycle. It is mostly used in a ``bottom up'' fashion, suggested by the principles of object orientation, where the composition of simple objects to a complex one plays a central role.

Test on Zero in Petri Nets

1982
In this note we discuss some aspects of nets (i. e. Petri-nets, place/transition nets, P/T-nets) augmented by inhibitor arcs. An inhibitor arc connects a transition t with a place p. For such a transition the firing rule is modified as follows. Transition t fires under the usual conventions, when p is empty, but is inhibited from firing, if p contains ...
