“…The design of such environment as a virtual space for scientific research and intelligent searching (virtual lab) should be based on an architectural concept for the structural organization of the system components (as an initial step) [3] . A part of this concept is the allocation of the system resources.…”

“…This model permits to formalize the access processes and information servicing. There are different papers which discuss the problem of architectural design (Afsarmanesh et al, 2010), (Ramasundaram et al, 2005), (Grygárek, Milata and Vavříček, 2007). In the last paper a system called Virtlab, which allows to access laboratory equipment remotely via Internet and the architectural development and modifications are discussed.…”

The purpose of the virtual laboratory is to propose an intellectual space for organization of the on-line work in specialized field of knowledge. The research presented in this paper is linked with the research carried out within the frame work of a two year scientific project. The main goal of the project team is to develop a Virtual Research Laboratory (VRL) as a collection of relatively independent distributed virtual mediums, search machine, software instruments and tools for specific research organization in the field of the modern electronic and computer technologies. The life cycle models for software development propose a system investigation and evaluation by using suitable apparatus to determine the adequate structural organization during the phase of the architectural design. In this reason, the goal of this paper is to present an investigation of the defined architecture by using the asynchronous apparatus of Petri Nets (PN) as a second phase of the project work concerning the VRL development. The PN model defining and the carried out research are based on the results obtained during the first phase of the project work-conceptual model defining, formalization, preliminary evaluation and general architecture building. The formal description is based on the fact that each process of the information servicing in the virtual environment could be treated as a sequence of events (states) that generates requests for access to different information resources (relations) via Internet. This formal description permits to make a deterministic model of the information service as a sequence of active events and transactions between them that could be realized by the asynchronous PN apparatus. The defined PN-model describes the evaluated object as a sequence of events (presented by transactions) that could be realized if all related conditions (presented by input places) are fulfilled. In this reason the PN model describes the information servicing in the evaluated VRL as a collection of transactions and position with defined relations between them. Some important experimental results and assessments are discussed.

“…Virtual Laboratory (VL) is a heterogeneous, distributed environment, which allows scientists all over the world to work on a common group of projects [1]. This environment should allow conducting experiments with the usage of physical devices, doing simulation using the computational application, and communication between users working on the same topic.…”

In the paper some dynamic measurement scenarios conception is presented. The Dynamic Measurement Scenarios (DMS) are used for advanced workflow control in the Virtual Laboratory system. It facilitates defining and monitoring the measurement process from the preparation stage through experimental and computational processes to results analysis (based on the achieved visualization data). DMS often consists of many different tasks connected by links with specified conditions. To execute DMS we need a special application (during the definition process) on the one hand and on the other hand a sophisticated (and complex) module is needed for manage and control specified workflow. The described issues are illustrated by Nuclear Magnetic Resonance (NMR) laboratory examples.
