Abstract- Pressure safety relief valve is the key component in any system where pressure rising could be hazardous to safety of the workers as well as plant. Though electronically operated safety controls are there, but to take care of any malfunctioning in it, mechanically operated relief valve is necessary. In oil refinery sector, safety is of prime important. The clay canisters are used to refine the oil. Sometimes these canisters get clogged and pressure rising may take place. The key requirement of process is to relieve this pressure rise in no time. Conventional valves are unable to fulfill that requirement. This paper focuses on design and analysis of an emergency safety valve by Design by Analysis (DBA) approach. From the data given by the client, suitable valve is designed using FEA. The working environment is hazardous & explosive; hence ASME code is used to design. This valve is a onetime operating valve used as tertiary safety arrangement for critical applications.

Generalized methods and solvers for noise removal from piecewise constant signals. I. Background theory

Certain two dimensional topological field theories can be interpreted as string theory backgrounds in which the usual decoupling of ghosts and matter does not hold. Like ordinary string models, these can sometimes be given space-time interpretations. For instance, three-dimensional Chern

We review the holographic correspondence between field theories and string/M theory, focusing on the relation between compactifications of string/M theory on Anti-de Sitter spaces and conformal field theories. We review the background for this correspondence and discuss its motivations

Emerging adulthood is proposed as a new conception of development for the period from the late teens through the twenties, with a focus on ages 18-25. A theoretical back-ground is presented, Then evidence is provided to support the idea that emerging adulthood is a distinct period de

in seven organizations, and results support its validity. A number of special features of the model are discussed (including its use as a basis for the diagnosis of jobs and the evaluation of job redesign projects), and the model is compared to other theories of job design. Work redesign is becoming

We describe the basic assumptions and key results of loop quantum gravity, which is a background independent approach to quantum gravity. The emphasis is on the basic physical principles and how one deduces predictions from them, at a level suitable for physicists in other areas such as string
