During the years 1950-1970 there was extensive development of control theory and its application. This paper explores the influence of the rapid development of the digital computer and associated enabling technologies on the field of control systems. A brief outline of digital computer and control theory development is given followed by an account of the effect of the digital computer on proces...

Traditional Digital Libraries require human editorial control over the lifecycles of digital objects contained therein. This imposes an inherent (human) overhead on the maintenance of these digital libraries, which becomes unwieldy once the number of important information units in the digital library becomes too large. A revised framework is needed for digital libraries that takes the onus off ...

Control systems are mostly modelled in continuous time. Implementation however happens in general by digital computers (mostly microprocessors), which influences the behavior of the control system. This makes a well-defined method for modelling of digital control systems desirable. In the past Mecal Applied Mechanics BV simulated digital control systems as an analog system with a time delay in ...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. despite cone beam computed tomography (cbct) has significantly enhanced image quality compared to digital radiography (dr) which aid the diagnosis, artifacts has remained as a problem in vrf detection . th...

Public media and researchers in different areas have recently focused on perhaps unexpected problems that derive from an excessive frequent use of technology, giving rise to a new kind psychological “digital” wellbeing. Such novel pressing topic has fostered, both the academia industry, emergence variety digital self-control tools allowing users self-regulate their technology through interventi...
