DBC based Face Recognition using DWT

Jagadeesh H S
2012 Signal & Image Processing An International Journal  
In this paper, we propose DBC based Face Recognition using DWT (DBC- FR) model. The Poly-U Near Infra Red (NIR) database images are scanned and cropped to get only the face part in pre-processing.  ...  The LL subband of size 50*50 is converted into 100 cells with 5*5 dimention of each cell. The Directional Binary Code (DBC) is applied on each 5*5 cell to derive 100 features.  ...  ACKNOWLEDGEMENT I would like to thank Department of Electronics and Communication Engineering, Rayalaseema University, Kurnool -518002, Andhra Pradesh, India for allowing me to pursue research work.  ...

CAN Database Verification Framework Using UPPAAL

Beomyeon Cho, Taewook Kim, Jin-Young Choi
2017 Journal of clean energy technologies  
Index Terms-Controller area network, DBC, formal verification, UPPAAL.  ...  In this paper, we propose a framework composed of UPPAAL and a DBC2XML component, which automatically generates a UPPAAL model from a CAN database and show how to verify the CAN database using this framework  ...  However, in order to change the priority dynamically, the application layer's algorithm must be involved in MAC (Media Access Control), which is the role of the data link layer.  ...

Apuama: Combining Intra-query and Inter-query Parallelism in a Database Cluster [chapter]

Bernardo Miranda, Alexandre A. B. Lima, Patrick Valduriez, Marta Mattoso
2006 Lecture Notes in Computer Science  
C-JDBC is a successful database cluster that offers inter-query parallelism and controls database replica consistency but cannot accelerate individual heavy-weight queries, typical of OLAP.  ...  We validated Apuama on a 32-node cluster running OLAP queries of the TPC-H benchmark on top of PostgreSQL.  ...  Such DBMS provides transparent access to the partitioned database and has full control over the parallel query execution plan. This is not the case for DBC.  ...

Database Computers—A Step Towards Data Utilities

Baum, Hsiao
1976 IEEE transactions on computers  
The concept of the data utility as a database system capable of supporting a data model, a large-scale on-line store, and concurrent user access has emerged in recent years.  ...  A summary of previous activities and a discussion of the state of the art of database computers is given. An attempt is made to suggest guidelines for future database computer architecture research.  ...  A major benefit of a data model is that it provides a unified way to specify access to, and control of, the database.  ...

1989 Proceedings of the 1989 ACM SIGMOD international conference on Management of data - SIGMOD '89  
Today's DBMSs are unable to support the increasing demands of the various applications that would like to use a DBMS. Each kind of application poses new requirements for the DBMS.  ...  To support these features, the database query language processor must be very powerful and highly extensible.  ...  We are grateful to Bruce Lindsay, She1 Finkelstein, John McPherson, Pat &linger, Irv Traiger, Paul Wilms and several anonymous referees who carefully and constructively read a draft of this paper.  ...
