this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

Retinal functional imager (RFI) is a unique non-invasive functional imaging system with novel capabilities for visualizing the retina. The objective of this review was to show the utility of non-invasive functional imaging in various disorders. Electronic literature search was carried out using the websites www.pubmed.gov and www.google.com. The search words were retinal functional imager and n...

Representing and selecting patterns remains largely an empirical task. It is difficult to recognize when to apply a given pattern, as well as the consequences its application could generate. This creates the need for extensions to the existing pattern representation. Elsewhere, we have proposed an explicit representation of the forces involved in a pattern and their interrelationships. It inter...

Illustrations provide visual support for transmitting a communication goal with regard to an illustration subject and a target audience. A set of presentation variables exists supporting this task. This set has proven valuable for expressing illustration information. To broaden the spectrum of illustration techniques, this work introduces the notion of dynamic presentations for illustration pur...
