To achieve effective 3D shape retrieval, there is a crucial need for efficient shape matching methods. This paper introduces a new method for 3D shape matching, which uses a simplified octree representation of 3D mesh models. The simplified octree representation was developed to improve time and space efficiency over prior representations. The proposed method also stores octree information in extensible markup language format, rather than in a new proprietary data file type, to facilitate comparing models over the Internet.


Big data is one of the most influential technologies of the modern era. However, in order to support maturity of big data systems, development and sustenance of heterogeneous environments is requires. This, in turn, requires integration of technologies as well as concepts. Computing and storage are the two core components of any big data system. With that said, big data storage needs to communicate with the execution engine and other processing and visualization technologies to create a comprehensive solution. This brings the facet of big data file formats into picture. This paper classifies available big data file formats into five categories namely text-based, row-based, column-based, in-memory and data storage services. It also compares the advantages, shortcomings and possible use cases of available big data file formats for Hadoop, which is the foundation for most big data computing technologies. Lastly, it provides a discussion on tradeoffs that must be considered while choosing a file format for a big data system, providing a framework for creation for file format selection criteria.

In the current study a steganography approach utilized to hide various data file format in wave files cover. Lest significant bit insertion (LSB) used to embedding a regular computer files (such as graphic, execution file (exe), sound, text, hyper text markup language (HTML) …etc) in a wave file with 2-bits hiding rates. The test results achieved good performance to hide any data file in wave file.

ABSTRACT # 2017-234 The California Department of Fish and Wildlife, Office of Spill Prevention and Response (OSPR) has drafted a “Data Management and Sharing Plan” document for use in drills and oil spill response in California. Implementation of this plan will help to avoid compartmentalized isolation of information within the ICS units and sections, will facilitate data dissemination throughout the broader response community, and provide continuance throughout staff changes over a prolonged response. The OSPR document is a modified version of a document first created by the National Oceanic and Atmospheric Administration, Office of Response and Restoration (OR&R)1. In May of 2015 the OR&R document was adapted by OSPR and OR&R for use at the Refugio Pipeline Spill in Santa Barbara, California. This was the first use of such a document at an oil spill response in California. That document version has been subsequently revised by OSPR. The OSPR document retains all of the components of the original OR&R version but has been re-formatted in order to replace technological jargon with plain English to accommodate Incident Commanders and others less familiar with Geographic Information System (GIS) specific technical terms. The document addresses the use of a GIS based Common Operational Picture (COP), specific essential elements of information to be collected, data management, data sharing, requirements for field reporting, data quality control, data file formats, and data archiving. The current OSPR document is designed as a template for regular use by California’s State on Scene Coordinator (SOSC), and can be easily filled out and modified to the specific needs of any oil spill response incident.

MechXML is an XML-based language aimed at describing multibody systems and their simulations (see a more detailed description in [1]). With the appropriate easy-to-build parsers, a data file written in this language can be executed with little or no modification at all in many commercial and research-oriented programs. The purpose of this paper is twofold: to introduce briefly this language and to describe with more detail the new developments that allow the definition of continuous control subsystems. The definition of controls is based on block diagrams. The user defined functions are a general way to customize multibody simulation software so as to enable it to deal with arbitrary forces and constraints. They are described here because they can be used to describe the actions of control systems, too. At the end, a file written according to the rules of MechXML is parsed and run in two programs as different as MSC.ADAMS and SimMechanics.
