Developing a distributed electronic health-record store for India
The DIGHT project is addressing the problem of building a scalable and highly available information store for the Electronic Health Records (EHRs) of the over one billion citizens of India
Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach
Unified Modelling Language (UML) is the most popular modelling language use for
software design in software development industries with a class diagram being the
most frequently use diagram. Despite the popularity of UML, it is being affected by
inconsistency problems of its diagrams at the same or different abstraction levels.
Inconsistency in UML is mostly caused by existence of various views on the same
system and sometimes leads to potentially conflicting system specifications. In
general, syntactic consistency can be automatically checked and therefore is
supported by current UML Computer-aided Software Engineering (CASE) tools.
Semantic consistency problems, unlike syntactic consistency problems, there exists
no specific method for specifying semantic consistency rules and constraints.
Therefore, this research has specified twenty-four abstraction rules of class‟s relation
semantic among any three related classes of a refined class diagram to semantically
equivalent relations of two of the classes using a logical approach. This research has
also formalized three vertical semantic consistency rules of a class diagram
refinement identified by previous researchers using a logical approach and a set of
formalized abstraction rules. The results were successfully evaluated using hotel
management system and passenger list system case studies and were found to be
reliable and efficient
Community Detection and Growth Potential Prediction from Patent Citation Networks
The scoring of patents is useful for technology management analysis.
Therefore, a necessity of developing citation network clustering and prediction
of future citations for practical patent scoring arises. In this paper, we
propose a community detection method using the Node2vec. And in order to
analyze growth potential we compare three ''time series analysis methods'', the
Long Short-Term Memory (LSTM), ARIMA model, and Hawkes Process. The results of
our experiments, we could find common technical points from those clusters by
Node2vec. Furthermore, we found that the prediction accuracy of the ARIMA model
was higher than that of other models.Comment: arXiv admin note: text overlap with arXiv:1607.00653 by other author
Rethinking the education of chemists - the odyssey is over, time for action!
Chemistry is a mature discipline with a distinguished pedigree and a long tradition, but times are changing and student numbers in chemistry are declining. The need for a reappraisal of what constitutes chemistry and a chemistry education at the beginning of the new millennium, is apparent. The paper examines some of the current issues surrounding chemistry and chemistry teaching and suggests ways in which we might go forward. A message of vision and imagination, applying a little of the ideals of Zarathustra in the setting of, '2001, A Chemistry Odyssey', is promulgated. [Chem. Educ. Res. Pract.: 2003, 4, 83-96]
A database management capability for Ada
The data requirements of mission critical defense systems have been increasing dramatically. Command and control, intelligence, logistics, and even weapons systems are being required to integrate, process, and share ever increasing volumes of information. To meet this need, systems are now being specified that incorporate data base management subsystems for handling storage and retrieval of information. It is expected that a large number of the next generation of mission critical systems will contain embedded data base management systems. Since the use of Ada has been mandated for most of these systems, it is important to address the issues of providing data base management capabilities that can be closely coupled with Ada. A comprehensive distributed data base management project has been investigated. The key deliverables of this project are three closely related prototype systems implemented in Ada. These three systems are discussed
