Missing data is a large-scale challenge to research and investigate. It reduces the statistical power produces negative consequences that may introduce selection bias on data. Many approaches handle this problem have been introduced. The main suggested are either missing values be ignored (removed) or imputed (filled in) with new values. This paper uses second method. Possible worlds possible c...

We propose a theoretical scheme to improve the resolution and precision of phase measurement with parity detection in Mach-Zehnder interferometer by using nonclassical input state which is generated applying number-conserving generalized superposition products (GSP) operation, (saa^{{\dag}}+ta^{{\dag}}a)^{m} s^2+t^2=1, on two-mode squeezed vacuum (TMSV) state. The properties proposed GSP-TMSV a...

The task of multi-turn text-to-SQL semantic parsing aims to translate natural language utterances in an interaction into SQL queries order answer them using a database which normally contains multiple table schemas. Previous studies on this usually utilized contextual information enrich utterance representations and further influence the decoding process. While they ignored describe track state...

The need for tailor-made data management is apparent in database research. There is an impressive body of research on extensible or customizable DBMS like kernel systems or component DBMS. Nevertheless, all these approaches have drawbacks, e.g., regarding customizability or performance, and there is no general solution for efficient development of tailorable DBMS. Novel software engineering tec...

Web applications are popular targets of security attacks. One common type of such attacks is SQL injection, where an attacker using specially crafted inputs, causes a web application to generate and send a query that functions differently than the programmer intended. Thus a diagnostic feature of SQL injection attacks is that they change the intended syntactic structure of queries issued. This ...
