Query evaluation techniques for large databases
- ACM COMPUTING SURVEYS
, 1993
"... Database management systems will continue to manage large data volumes. Thus, efficient algorithms for accessing and manipulating large sets and sequences will be required to provide acceptable performance. The advent of object-oriented and extensible database systems will not solve this problem. On ..."

-relational database systems, including iterative execution of complex query evaluation plans, the duality of sort- and hash-based set matching algorithms, types of parallel query execution and their implementation, and special operators for emerging database application domains.
Layered depth images
, 1997
"... In this paper we present an efficient image based rendering system that renders multiple frames per second on a PC. Our method performs warping from an intermediate representation called a layered depth image (LDI). An LDI is a view of the scene from a single input camera view, but with multiple pix ..."

system, McMillan's warp ordering algorithm can be successfully adapted. As a result, pixels are drawn in the output image in back to front order. No z-buffer is required, so alpha-compositing can be done efficiently without depth sorting. This makes splatting an efficient solution to the resampling
Indexing and Querying XML Data for Regular Path Expressions
- IN VLDB
, 2001
"... With the advent of XML as a standard for data representation and exchange on the Internet, storing and querying XML data becomes more and more important. Several XML query languages have been proposed, and the common feature of the languages is the use of regular path expressions to query XML ..."

data. This poses a new challenge concerning indexing and searching XML data, because conventional approaches based on tree traversals may not meet the processing requirements under heavy access requests. In this paper, we propose a new system for indexing and storing XML data based on a
Delay Analysis of Gated Polling Algorithm for DBA Scheme in an EPON
"... Abstract:- In this paper, we investigate the mean packet delay of a dynamic bandwidth allocation(DBA) scheme in an Ethernet passive optical network(EPON). We focus on the interleaved polling algorithm with a gated service discipline and two stage queues. We assume that input packets arrive at an opt ..."

Investigation of the DBA algorithm design space for EPONs
- IEEE/OSA J. Lightwave Technol
, 2012
"... Abstract—The implications of the main components of dynamic bandwidth allocation (DBA) algorithms in ethernet passive optical networks, namely grant scheduling framework, grant sizing, and grant scheduling, have to date been examined in isolation. In contrast, we conduct a comprehensive throughput-d ..."

Fuzzy Logic Embedded in Prediction-Based DBA for Differentiated Services on EPONs
"... A Fuzzy Prediction-based Dynamic Bandwidth Allocation (FPDBA) algorithm is proposed to enhance the differentiated services for EPONs based on the Prediction-based Fair Excessive Bandwidth Reallocation (PFEBR) in our previous work. The PFEBR proposed an Early-DBA mechanism which improves prediction a ..."

bandwidth allocation (DBA) is one of the most critical issues in EPON network. In this paper, a new DBA algorithm is proposed to support QoS and to get higher performance. The proposed algorithm could avoid bandwidth wastes result from dynamically allocation from differentiated services and unused bandwidth
