A single framework has some problems in building enterprise application, such as low efficiency of system development, poor expansibility, high coupling between layers and complex structure, etc. Aiming at these problems, a web application framework based on Strut2, Spring and Hibernate (S2SH) is put forward. By making use of the completeness of Struts2 in the presentation layer, the flexibility of...
The suppression effect of Bacillus amyloliquefacien Ba33 against TMV and PVY by biological detect through necrotic lesions host and RNA detect through RT-PCR was studied. The result showed that the suppression ratio of necrotic lesions against TMV and PVY was 95.25% and 99.22% respectively. And Ba33 could suppression RNA replication of TMV and PVY in Nicotiana tabacum var. NC89 leaves from 24 to 84h...
A detailed analysis of supervisory control for Petri net based discrete event system with uncontrollable transitions, especially important, for OR-logics linear constraint, a new method for constructing a Petri net feedback controller based on monitor and inhibitor arcs is presented. Constraints are classified into admissible and inadmissible constraints. After Matrix-Transformation, if the constraint...
