Abstract Quantitative nuclear magnetic resonance (qNMR) is considered as a powerful tool for multicomponent mixture analysis well the purity determination of single compounds. Special attention currently paid to training operators and study directors involved in qNMR testing. To assure that only qualified personnel are used sample preparation at our GxP-accredited laboratory, weighing test was ...

Traditionally, workflow modeling is typically done by interviews or questionnaires which stay quite limited for the acquisition of workflow models and their adaptation to changing requirements. In order to build such model, this paper proposes to “reverse the process”. The approach, we propose, is able to acquire workflow model from workflow log, which contains information about execution event...

Immunoassays play a pivotal role in the clinical laboratory. In the coagulation section of the laboratory, they are used as an aid for diagnosis of deep vein thrombosis or pulmonary embolism, thrombophilia screening, or detection of coagulation factor deficiencies, respectively. Enzyme-linked immunosorbent assay (ELISA) and latex agglutination immunoassay technologies are currently most widely ...

Every time a workflow solution is conceived there is a large amount of functionality that is eventually reinvented and redeveloped from scratch. Workflow management systems from academia to the commercial arena exhibit a myriad of approaches having as much in common as in contrast with each other. Efforts in standardizing a workflow reference model and the gradual endorsement of those standards...

As the number of services and the size of data involved in workflows increases, centralised orchestration techniques are reaching the limits of scalability. In the classic orchestration model, all data passes through a centralised engine, which results in unnecessary data transfer, wasted bandwidth and the engine to become a bottleneck to the execution of a workflow. This paper presents and eva...

Previous workflow mining works have concentrated their efforts on process behavioral aspects. Although powerful, these proposals are found lacking in functionalities and performance when used to discover transactional workflow that cannot be seen at the level of behavioral aspects of workflow. Their limitations mainly come from their incapacity to discover the transactional dependencies between...

Spacecraft software automatic testing plays an essential role in spacecraft testing field for a decade. However, less attention has been paid on it based on workflow methodology. In this paper we introduce workflow technology into testing for improving the automation of spacecraft software testing. Firstly we present a spacecraft testing process definition language STPDL. Then workflow patterns...

Infectious gastroenteritis is a global health problem associated with high morbidity and mortality rates. Rapid and accurate diagnosis is crucial to allow appropriate and timely treatment. Current laboratory stool testing has a long turnaround time (TAT) and demands highly qualified personnel and multiple techniques. The need for high throughput and the number of possible enteric pathogens comp...

Workflow management systems (WfMSs) are useful tools for bioinformaticians. As experiences with using WfMSs accumulate, shortcomings of current systems become apparent. In this paper, we focus on practical issues that hinder WfMS users and that arise in the design and execution of workflows, and in access of web services. We present e-BioFlow, a workflow engine that demonstrates in which way a ...
