AN ACTIVITY OVERLAPPING ALGORITHM FOR CONSTRUCTION

by Jae-Seob Lee , Keith R Molenaar , Susan M Bogus , James E Diekmann
"... ABSTRACT Concurrent engineering has been used to reduce project completion time. Although several studies have been directed toward the issue of concurrent engineering in construction engineering and management, they have primarily focused on the process in the design phase and examined the informa ..."

engineering overlapping techniques for design. A pilot case study demonstrates the applicability of the proposed algorithm into the construction industry.

Leveraging user query log: Toward improving image data clustering

by Hao Cheng, Kien A. Hua, Khanh Vu - In CIVR ’08: ACM International Conference on Image and Video Retrieval , 2008
"... Image clustering is useful in many retrieval and classifica-tion applications. The main goal of image clustering is to partition a given dataset into salient clusters such that the images in each cluster appear visually similar to each other compared with those in other clusters. In this paper, we p ..."

pro-pose a semi-supervised clustering algorithm, which leverages the accumulated user query log to guide the clustering pro-cess. Guided by the log file, our method arranges images into small groups and constructs a graph that captures the dissimilar relations between the groups. Each group is as

Query Evaluation with Constant Delay

"... I am grateful to Luc Segoufin who kindly accepted me to be his PhD student. He introduced me to the problem of query enumeration and encouraged me to look for the answers to all the questions that emerged during our collaboration. He was a truly great advisor, always supportive and available for dis ..."

Self-concordance at work: Toward understanding the motivational effects of transformational leaders.

by Joyce E Bono , Timothy A Judge - Academy of Management Journal, , 2003
"... We extend existing theories by linking transformational leadership to "self-concordance" at work. In two studies using diverse samples and methods, leader behaviors were associated with follower tendencies to set self-concordant goals. In general, followers of transformational leaders vie ..."

that links internal self-regulation, goal-directed effort, and goal attainment. Our purpose was to gain a better understanding of the reasons why followers of transformational leaders exhibit increased motivation, job satisfaction, organizational commitment, and job performance. We did this by testing one

Query Merging: Improving Query Subscription Processing in a Multicast Environment

by Arturo Crespo, Orkut Buyukkokten, Hector Garcia-molina - IEEE Trans. on Knowledge and Data Engineering
"... This paper introduces techniques for reducing data dissemination costs of query subscriptions in a multicast environment. The reduction is achieved by merging queries with overlapping, but not necessarily equal, answers. The paper formalizes the query-merging problem and introduces a general fram ..."

framework and cost model for evaluating merging. We prove that the problem is NP-hard and propose exhaustive algorithms and three heuristic algorithms: the Pair Merging Algorithm, the Directed Search Algorithm and the Clustering Algorithm. We develop a simulator, which uses geographical queries as a

Improving the Query Performance of High-Dimensional Index Structures by Bulk Load Operations

by Stefan Berchtold, Christian Böhm, Hans-Peter Kriegel - IN PROC. CONFERENCE ON EXTENDING DATABASE TECHNOLOGY, LNCS 1377 , 1998
"... In this paper, we propose a new bulk-loading technique for high-dimensional indexes which represent an important component of multimedia database systems. Since it is very inefficient to construct an index for a large amount of data by dynamic insertion of single objects, there is an increasing i ..."

interest in bulk-loading techniques. In contrast to previous approaches, our technique exploits a priori knowledge of the complete data set to improve both construction time and query performance. Our algorithm operates in a mannar similar to the Quicksort algorithm and has an average runtime

Collision Queries using Oriented Bounding Boxes

by Stefan Gottschalk , 2000
"... Collision Queries using Oriented Bounding Boxes Under the direction of Dinesh Manocha and Ming Lin Bounding volume hierarchies (BVHs) have been used widely in collision detection algorithms. The most commonly used bounding volume types are axis-aligned bounding boxes (AABBs) and spheres, which hav ..."

Methods A novel non-overlapping bi-clustering algorithm for network generation using Living Cell Array data

by P. T. Foteinou, K. R. King, M. L. Yarmush, I. P. Androulakis, Dr. Olga Troyanskaya
"... Motivation: The living cell array quantifies the contribution of activated transcription factors upon the expression levels of their target genes. The direct manipulation of the regulatory mechanisms offers enormous possibilities for deciphering the machinery that activates and controls gene express ..."

Towards a Query Language for Multihierarchical XML: Revisiting XPath

by Ionut E. Iacob - In WebDB , 2005
"... In recent years it has been argued that when XML encodings become complex, DOM trees are no longer adequate for query processing. Alternative representations of XML documents, such as multi-colored trees [7] have been proposed as a replacement for DOM trees for complex markup. In this paper we consi ..."
Abstract - Cited by 10 (2 self) - Add to MetaCart
consider the use of Generalized Ordered-Descendant Directed Acyclic Graphs (GODDAGs) for the purpose of storing and querying complex document-centric XML. GODDAGs are designed to store multihierarchical XML markup over the shared PCDATA content. They support representation of overlapping markup, which
