Quantitative Aspects of Requirements Evolution
Requirements Evolution is considered one of the most critical issues in developing computer-based systems. Despite the recognised role of requirements in Software Engineering, Requirements Evolution still remains a phenomenon little understood from both quantitative and qualitative perspectives. This paper investigates our ability to understand the Requirements Evolution Process by means of met...
متن کاملQuantitative Aspects of Ventricular Repolarization:
Introduction: QT dispersion assesses repolarization inhomogeneity on 12-lead standard ECG. However, the implications of the electrical cardiac vector during the repolarization phase (the T wave loop) with the genesis of this phenomenon are unknown. Methods and Results: The aim of this study was to explore conventional 12-lead resting ECG QT dispersion and the corresponding morphology of the spa...
متن کاملTemporal Quantitative Aspects of Creativity
In this paper we argue that complex qualitative phenomena such as creativity can and should be investigated from a quantitative viewpoint and, in particular, within the framework of a time-constrained model of memory.
متن کاملQuantitative Aspects of Embedded Systems
Embedded software controls the core functionality of many systems: it controls telephone switches and satellites, drives the climate control in our offices and cars, runs pacemakers, is at the heart of our power plants, and makes our cars and TVs work properly. As such systems are massively encroaching on daily life, our reliance on embedded software is growing rapidly. But, how justifiable is ...
متن کاملQuantitative Aspects of Transmitter Release
The opener-stretcher motor neuron in crayfish makes 50 endings upon each of 1200 muscle fibers. We have calculated the quantal content of junctional potentials produced by individual terminals and by the whole cell at various physiological frequencies. The results show that when the motor neuron is active at 20 impulses/second, it releases 50 quanta/impulse per muscle fiber, or a total of 4.5 x...
