Graph databases with a custom non-relational backend promote themselves to outperform relational databases in answering queries on large graphs. Recent empirical studies show that this claim is not always true. However, these studies focus only on pattern matching queries and neglect analytical queries used in practice such as shortest path, diameter, degree centrality or closeness centrality. ...

background: maternal mortality ratio (mmr) is one of the main indicators of the millennium development goals and its accurate estimation is very important for the countries concerned. the objective of this study is to evaluate the applicability of capture‑recapture (crc) as an analytical method to estimate mmr in countries. methods: we used the crc method to estimate mmr in iran for 2004 and 20...

We demonstrate BIIIG (Business Intelligence with Integrated Instance Graphs), a new system for graph-based data integration and analysis. It aims at improving business analytics compared to traditional OLAP approaches by comprehensively tracking relationships between entities and making them available for analysis. BIIIG supports a largely automatic data integration pipeline for metadata and in...

Any member of the United Nations has to carry out an entire national census between the years 2005 and 2014. While the demographic characteristics of the population in the still very widespread traditional census are determined by directly contacting citizens, the new kind of register-based census represents a radical shift in the way censuses are conducted, involving an entirely new set of tas...

In this paper we give the new improved analytical method of triple stub tuner for matching load impedances to provide maximum power transfer between a generator and load. The stubs are connected in series with line at appropriate distances from characteristic transmission stabs different. points on determination length first near limit lengths second found which is possible. third directly obta...

In this paper we give the new improved analytical method of triple stub tuner for matching load impedances to provide maximum power transfer between a generator and load. The stubs are connected in parallel with line at appropriate distances from characteristic transmission stabs different. points on determination length first near limit lengths second found which is possible. third directly ob...

An analytical model for the performance analysis of a multiple input queued asynchronous transfer mode (ATM) switch is presented in this paper. The interconnection network of the ATM switch is internally nonblocklng and each input port malntahts a separate queue of cells for each output port The switch uses parallel iterative matching (PIM) [7] to Ford the maxlmal matching between the input and...
