Predictive maintenance (PdM) is an advanced technique to predict the time failure (TTF) of a system. PdM collects sensor data on health system, processes information using analytics, and then establishes data-driven models that can forecast system failure. Deep neural networks are increasingly being used as these owing their high predictive accuracy efficiency. However, deep often criticized “b...

Road networks are critical infrastructures within any region and it is imperative to maintain their conditions for safe effective movement of goods services. Management, therefore, plays a key role ensure consistent efficient operation. However, significant resources required perform necessary maintenance activities achieve high levels service. Pavement can typically be very expensive decisions...

The use of a simple 50%-50% box score of decisions for parents and districts, respectively, is a false measure of the impartiality of hearing officers under the Individuals with Disabilities Education Act (IDEA). This analysis canvasses relevant structural factors that the stakeholders, the mass media, and the professional literature have failed to recognize both generally and systematically. T...

Airline maintenance operations affect the potential for flight delays and can also affect flight safety if signals of technical problems are missed or misinterpreted. In this paper, we use a probabilistic risk analysis model, represented by an influence diagram, to quantify the effect of an airline’s maintenance policy on delays, cancellations and in-flight safety. The model represents the lead...

The Supreme Court decision on school desegregation 25 years ago-Brown v. Board o f ~ducatio-ushered in an era in which the law courts have carried an ever-growing share of the burden of social reform and policy change in this country. Even though several current members of the Supreme Court were appointed as "strict constructionists," and think of themselves as not in the business of setting so...

The present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using Markov Birth-Death process and probabilistic approach. In present paper, the feed water system consists of four subsystems. After drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

Current software architecture practices have been focused on modeling and documenting the architecture of a software system by means of several architectural views. In practice, the standard architecture documentation lacks explicit description of the decisions made and their underlying rationale, which often leads to knowledge loss. This fact strongly affects the maintenance activities as we n...

Architectural design decisions deserve to be first class entities in the process of developing complex software-intensive systems. Preserving the graphs of decisions and all their interdependencies will support the evolution and maintenance of such systems. In this paper we present a possible ontology of architectural design decisions, their attributes and relationships, for complex, software-i...

Production scheduling deals with scheduling production jobs on a machine (single or multiple) in order to optimise a specific objective such as total weighted completion times or total weighted tardiness. The assumption that machines are always available for processing jobs is generally used in the production scheduling literature. In reality, machines often are unavailable due to preventive ma...
