Complex real-time systems exhibit dynamic behaviours on many different time levels. To cope with the wide range of time scales and produce more dependable computer-based systems, we develop a timebands model that can explicitly recognise a finite set of distinct time bands in which temporal properties and associated behaviours are described. We formalise the timebands model by using the semanti...

olive oil is one of the foods that are preferred by consumers seeking healthy nutrition. healthy, safety and high quality olive oil production can only be achieved in olive oil enterprises that follow these criteria. therefore, food safety and quality management systems should be placed in these olive oil enterprises. the aim of this study was to determine behaviors and attitudes of firm owners...

More and more programmers find their software being used in performance critical applications. Unfortunately, they have limited techniques at their disposal to help guarantee this particular aspect of their programs. There has been considerable activity in recent years on developing analysis techniques for hard real-time systems. Inevitably these techniques make simplifying assumptions so as to...

As a consequence of an increasing share of renewable energies, balancing electricity production and delivery requires efficient electricity markets. At the heart of electricity markets are Information Systems (IS) that coordinate demand and supply in real-time. IS has recently opened up an alternative towards increasing the efficiency of electricity markets by managing demand side resources; i....

Many wireless technologies are used to establish the communication between tags and readers. Most popular ones include WiFi, GPS, Infrared, Bluetooth, and active and passive RFID systems. Table 1 summarizes the differences of these technologies, their prominent features, and the performance that determine their suitability to different applications. There is no “one size fits all” solution when...

The journal Real-Time Systems publishes papers, short papers and correspondence articles that concentrate on real-time computing principles and applications. The contents include research papers, invited papers, project reports and case studies, standards and corresponding proposals for general discussion, and a partitioned tutorial on real-time systems as a continuing series. The range of cov...
