In contrast to the standard physical theories which model systems by the continuum, Petri proposed a combinatorial representation of a spacetime — concurrent structures (with occurrence nets as a special case thereof) in which notions corresponding to the relativistic concepts of world line and causal cone can be defined by means of the concurrency and causal dependence relations, repectively. ...

A Fuzzy Internal Model Controller (FIMC) is proposed for the control of MIMO systems with dead time. The controller is based on the well-known Internal Model Control (IMC) formulation but utilises a non-linear crisp consequent Fuzzy Relational Model (ccFRM) at its core. The use of the ccFRM allows an exact inverse of the process model to be used in the design of the controller. The feasibility ...

Major severe weather events can cause a significant loss of life and property. We seek to revolutionize our understanding of and ability to predict such events through the mining of severe weather data. Because weather is inherently a spatiotemporal phenomenon, mining such data requires a model capable of representing and reasoning about complex spatiotemporal dynamics, including temporally and...

This study draws on depth interviews with 49 managers in customer firms and 55 managers in supplier firms and on discussions with 21 managers in two focus groups to propose a new way of thinking about customer solutions. Extant literature and suppliers interviewed for this study view a solution as a customized and integrated combination of goods and services for meeting a customer’s business ne...

In Data Warehousing, Extraction-Transformation-Loading (ETL) are the key tasks that are responsible for the extraction of data from several sources, their cleansing, customization and insertion into data warehouse [10]. More specifically ETL tools are category of specialized tools with the task of dealing with data warehouse cleaning and loading problems. These task are very critical in every d...

Advertisement has long been used as a tool for informing and attracting audiences in different ways. This study aims at investigating the linguistic tools of advertisement in Persian on the basis of Halliday’s systemic-functional grammar theory. The data of this study were gathered from written and verbal commercial advertisements which were recorded and rewritten in order to investigate verbal...

The omnipresence of using Enterprise Resource Planning (ERP) systems to support business processes has enabled recording a great amount of (relational) data which contains information about the behaviors of these processes. Various process mining techniques have been proposed to analyze recorded information about process executions. However, classic process mining techniques generally require a...

The complex mechanisms in corporate education, where cognitive operations of individual learning intertwine with social processes of an organisational context, demand an extended theory of curriculum design that seeks to explain the existing successes and failures of training systems. The author advocates integrated design procedures that combine a systematic and relational approach. Empirical ...
