We present the design <strong>and</strong> implementation of the Virtual Microscope, a software system employing a client/server<br />
architecture to provide a realistic emulation of a high power light microscope. The system provides a form of completely<br />
digital telepathology, allowing simultaneous access to archived digital slide images by multiple clients. The main problem the<br />
system targets is storing <strong>and</strong> processing the extremely large quantities of data required to represent a collection of slides. The<br />
Virtual Microscope client software runs on the end user’s PC or workstation, while database software for storing, retrieving<br />
<strong>and</strong> processing the microscope image data runs on a parallel computer or on a set of workstations at one or more potentially<br />
remote sites. We have designed <strong>and</strong> implemented two versions of the data server software. One implementation is a<br />
customization of a database system framework that is optimized for a tightly coupled parallel machine with attached local<br />
disks. The second implementation is component-based, <strong>and</strong> has been designed to accommodate access to <strong>and</strong> processing of<br />
data in a distributed, heterogeneous environment. We also have developed caching client software, implemented in Java, to<br />
achieve good response time <strong>and</strong> portability across different computer platforms. The performance results presented show that<br />
the Virtual Microscope systems scales well, so that many clients can be adequately serviced by an appropriately configured<br />
data server.<br />

The authors’ methodology of creating e-learning content for the students of physiology, pathophysiology <strong>and</strong> biomedicine<br />
at the Faculty of Medicine is presented here. The design process from a formalized description of physiological reality to<br />
interactive educational software is described. Various tools an, used during the design - starting with the numerical simulation<br />
software Matlab/Simulink, through Macromedia Flash for interactive animations, Control Web or MS Visual Studio for user<br />
interface design to web publishing tools including the Macromedia Breeze learning management system. Also, various<br />
professions are involved - teachers, physicians, simulation/modeling experts, graphic designers <strong>and</strong> programmers. The aim is<br />
to provide students with software that helps them underst<strong>and</strong> the complex dynamics of physiological systems.<br />

Differential equations arise in many fields of application, such as in the simulation of phenomena in chemistry, physics,<br />
biology, medicine <strong>and</strong> so forth. These equations are generally in the form of initial value problems (IVPs), which can be<br />
extremely costly to solve when they are stiff due to the requirement of working with implicit methods. Implicit methods are<br />
costly because at each time step we need to solve implicit equations, which are nonlinear in general. Therefore, in such cases<br />
