Wakatobi National Park has a tropical marine ecosystem with typically dynamic aquatic resources, and it also has a potentially massive number of groupers such as red (Plectropomus leopardus) and black groupers (Plectropomus areolatus). However, the sustainability of the grouper resources has not been managed effectively and environmentally friendly. This study aims to determin...

a new method was introduced for frothing characterization of flotation frothers. method uses water recovery to develop a new frothability index named water recovery index (wri). new index was determined for some commercial frothers and results were compared with dynamic frothability index (dfi). results showed that water recovery index values follow the order of a-65 13016 s/mol > df-250 6292.4...

The problem considered in this article∗is how to evaluate image segmentations objectively. An image segmentation is the partition of an image into its constituent parts. Until recently, the evaluation of image segmentations has been largely subjective. Much work has been done in developing metrics for evaluating segmentations with respect to ground truth images. However, little has been done in...

This paper presents the IMine index, a general and compact structure which provides tight integration of item set extraction in a relational DBMS. Since no constraint is enforced during the index creation phase, IMine provides a complete representation of the original database. To reduce the I/O cost, data accessed together during the same extraction phase are clustered on the same disk block. ...

Ecient indexing in a class hierarchy is essential for the achievement of high performance in query evaluation for object database management systems. In this paper, we present a practical indexing scheme, index set, which provides good index con®guration for any real database environment. The proposed scheme considers the distribution of key values, as well as query patterns such as query weig...

We introduce a statistic pmaj(P ) for partitions of [n], and show that it is equidistributed with cr2, the number of 2-crossings, over all partitions of [n] with given sets of minimal block elements and maximal block elements. This generalizes the classical result of equidistribution for the permutation statistics inv and maj. © 2007 Elsevier Inc. All rights reserved.

Relational database management systems manages the tables with predefined indexes. In RDBMS indexes are created on the basis of attribute values. The Imine indexing scheme is used to index item sets in relational databases. The index creation is performed with out any constraints. IMine provides a complete representation of the original database. The Imine indexing scheme reduces the input/outp...

Building cities more sustainably through transit-oriented development (TOD) has become a principal planning concept in recent decades. The node-place model serves as an important tool for determining the TOD typology, combining consideration of station with transport network which it is located. A number studies have proposed addition new indicators to original model. However, importance bicycl...
