Complexity Analysis and Critical Factor Identity in Multimedia Social Systems

The rapid development of multimedia social systems makes the exchange and the share of the information between users more and more convenient. At the same time, it also makes that the multimedia social systems have complexity characteristic. Hence the traditional object-oriented analysis methods have been not able to suit this kind of saturation. This paper analyzes the complexity of social multimedia systems and proposes that the complexity performance of multimedia social systems includes the structure level, interactive behaviors and behavioral unpredictability. We also take an example to explain the shortcomings of the traditional object-oriented analysis method for solving the analysis and the design of complex systems. Based on this complexity analysis, we introduce the information entropy and propose an evaluation method for identifying the core and potential factors which have important influence on the operation of the whole multimedia social system. Finally, some simulation experiments and result analysis are given to our proposed framework. Both theoretical analysis and numerical simulations show that the proposed framework is a simple and effective new method to find out the core components within this kind of multimedia social system. The new program could realize a good user platform for achieving a high security and meanwhile meeting the user terminal platform privacy protection requirements. Therefore, this paper presents a new method to improve the security of multimedia social systems.

Extraction Method for Earthquake-Collapsed Building Information Based on High-Resolution Remote Sensing

At present, the extraction of earthquake disaster information from remote sensing data relies on visual interpretation. However, this technique cannot effectively and quickly obtain precise and efficient information for earthquake relief and emergency management. Collapsed buildings in the town of Zipingpu after the Wenchuan earthquake were used as a case study to validate two kinds of rapid extraction methods for earthquake-collapsed building information based on pixel-oriented and object-oriented theories. The pixel-oriented method is based on multi-layer regional segments that embody the core layers and segments of the object-oriented method. The key idea is to mask layer by layer all image information, including that on the collapsed buildings. Compared with traditional techniques, the pixel-oriented method is innovative because it allows considerably rapid computer processing. As for the object-oriented method, a multi-scale segment algorithm was applied to build a three-layer hierarchy. By analyzing the spectrum, texture, shape, location, and context of individual object classes in different layers, the fuzzy determined rule system was established for the extraction of earthquake-collapsed building information. We compared the two sets of results using three variables: precision assessment, visual effect, and principle. Both methods can extract earthquake-collapsed building information quickly and accurately. The object-oriented method successfully overcomes the pepper salt noise caused by the spectral diversity of high-resolution remote sensing data and solves the problem of same object, different spectrums and that of same spectrum, different objects. With an overall accuracy of 90.38%, the method achieves more scientific and accurate results compared with the pixel-oriented method (76.84%). The object-oriented image analysis method can be extensively applied in the extraction of earthquake disaster information based on high-resolution remote sensing.

Integration of multidimensional parameters of polarimetric synthetic aperture radar images for land use and land cover classification

Diverse parameters that are decomposed from quad polarimetric synthetic aperture radar (PolSAR) imagery become the important basis in the target recognition and classification. The selection of effective parameters is a very important research topic. This work aims to explore the algorithm of parameter selection based on the parametric statistics and multidimensional analysis. The proposed algorithm merges the parameters from different decomposed algorithms and the optimal parameters describing the backscattering characters of the targets are explored. The difference of parameters’ locations in three-dimensional spaces is the important basis of target differentiation. Based on the selected parameters, PolSAR images are classified using the object-oriented analysis and decision tree method. The experimental results indicate that the overall accuracy and Kappa coefficient of the classification using the integrated multidimensional parameters were higher than those using Freeman and H/A/α decomposed parameters. The advantage of this algorithm is to select optimal parameter combinations in multidimensional space by integrating many parameters from different decomposed algorithms.

As a case study, a petroleum reserve base auto-identify classification is selected as an example and the target is identified, in a better effective result by applications of the object-oriented method. The result appraising analysis indicates that object-oriented classification method to identify automatically high-resolution remote sensing images pattern object can get a high precision. The method of object-oriented has a widely potential application for remote sensing image automatic-identify classification in times to come.

Transferability of Object-Oriented Image Analysis Methods for Slum Identification

Updated spatial information on the dynamics of slums can be helpful to measure and evaluate progress of policies. Earlier studies have shown that semi-automatic detection of slums using remote sensing can be challenging considering the large variability in definition and appearance. In this study, we explored the potential of an object-oriented image analysis (OOA) method to detect slums, using very high resolution (VHR) imagery. This method integrated expert knowledge in the form of a local slum ontology. A set of image-based parameters was identified that was used for differentiating slums from non-slum areas in an OOA environment. The method was implemented on three subsets of the city of Ahmedabad, India. Results show that textural features such as entropy and contrast derived from a grey level co-occurrence matrix (GLCM) and the size of image segments are stable parameters for classification of built-up areas and the identification of slums. Relation with classified slum objects, in terms of enclosed by slums and relative border with slums was used to refine classification. The analysis on three different subsets showed final accuracies ranging from 47% to 68%. We conclude that our method produces useful results as it allows including location specific adaptation, whereas generically applicable rulesets for slums are still to be developed.

Hierarchical Cluster Analysis of a Convection-Allowing Ensemble during the Hazardous Weather Testbed 2009 Spring Experiment. Part I: Development of the Object-Oriented Cluster Analysis Method for Precipitation Fields

Abstract Convection-allowing ensemble forecasts with perturbations to model physics, dynamics, and initial (IC) and lateral boundary conditions (LBC) generated by the Center for the Analysis and Prediction of Storms for the NOAA Hazardous Weather Testbed (HWT) Spring Experiments provide a unique opportunity to understand the relative impact of different sources of perturbation on convection-allowing ensemble diversity. Such impacts are explored in this two-part study through an object-oriented hierarchical cluster analysis (HCA) technique. In this paper, an object-oriented HCA algorithm, where the dissimilarity of precipitation forecasts is quantified with a nontraditional object-based threat score (OTS), is developed. The advantages of OTS-based HCA relative to HCA using traditional Euclidean distance and neighborhood probability-based Euclidean distance (NED) as dissimilarity measures are illustrated by hourly accumulated precipitation ensemble forecasts during a representative severe weather event. Clusters based on OTS and NED are more consistent with subjective evaluation than clusters based on traditional Euclidean distance because of the sensitivity of Euclidean distance to small spatial displacements. OTS improves the clustering further compared to NED. Only OTS accounts for important features of precipitation areas, such as shape, size, and orientation, and OTS is less sensitive than NED to precise spatial location and precipitation amount. OTS is further improved by using a fuzzy matching method. Application of OTS-based HCA for regional subdomains is also introduced. Part II uses the HCA method developed in this paper to explore systematic clustering of the convection-allowing ensemble during the full 2009 HWT Spring Experiment period.

Mobile Devices, which are developed with the fast growing of the Internet, have flexible internet accessibility and can access the network anywere so that they can execute software applications. However, it is very challenging to deploy highly complex applications on mobile devices since they have limited resources. To overcome the limitation, researches on applying a concept of services to mobile applications have been proposed. Android is one of the popular mobile platforms and is designed to effectively execute mobile applications on the mobile devices having limited resources. Since service-based Android applications, which adopt a concept of services and Android platform, invoke remote services and are built with Android-specific components, they are much different from traditional software applications. Consequently, it is not straightforward to apply object-oriented (OO) analysis and design methods to developing service-based Android applications, although they have been frequently applied to developing traditional applications. In this paper, we present a process to develop service-based Android mobile applications, which extends a traditional OO development process. First, we raise design issues to be considered in developing service-based Android applications. Then, to solve the issues, we present detailed guidelines for essential phases of OO-based development process that are customized to service-based Android applications. Finally, to show applicability of the process, we perform a case study. The proposed design process is effectively utilized as a set of guidelines to develop service-based Android applications more systematically and effectively.

Site Characterization Using Integrated Imaging Analysis Methods on Satellite Data of the Islamabad, Pakistan, Region

We develop an integrated digital imaging analysis approach to produce a first-approximation site characterization map for Islamabad, Pakistan, based on remote-sensing data. We apply both pixel-based and object-oriented digital imaging analysis methods to characterize detailed (1:50,000) geomorphology and geology from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite imagery. We use stereo-correlated relative digital elevation models (rDEMs) derived from ASTER data, as well as spectra in the visible near-infrared (VNIR) to thermal infrared (TIR) domains. The resulting geomorphic units in the study area are classified as mountain (including the Margala Hills and the Khairi Murat Ridge), piedmont, and basin terrain units. The local geologic units are classified as limestone in the Margala Hills and the Khairi Murat Ridge and sandstone rock types for the piedmonts and basins. Shear-wave velocities for these units are assigned in ranges based on established correlations in California. These ranges include Vs30-values to be greater than 500 m/sec for mountain units, 200–600 m/sec for piedmont units, and less than 300 m/sec for basin units. While the resulting map provides the basis for incorporating site response in an assessment of seismic hazard for Islamabad, it also demonstrates the potential use of remote-sensing data for site characterization in regions where only limited conventional mapping has been done.

Instructional Design Paradigms: Is Object-Oriented Design Next?

The current systematic approaches taught to. and perhaps used by, instructional designer's share much in common with structured computer software design approaches. The computing field is currently undergoing major changes fostered by the growth of object-oriented (OO) analysis, design, and programming methods. The OO paradigm may also offer a revised focus for ID research. Several instructional design (ID) researchers are already adopting OO computing terminology. The suggested cross-over of OO from computing to instructional design is tied to design trends and ongoing research in II).

Enriching the class diagram concepts to capture natural language semantics for database access

Research on accessing databases using natural languages usually utilizes an intermediate logical form for the mapping process from natural languages to database query languages. However, there is still much that needs to be accomplished to bridge the gap between natural language constructs and database schemas. In this paper, we present a translation scheme for transforming natural language queries into relational algebra through the class diagram representations. Based on a logical form developed by extending the UML class diagram notations, a transformation model is presented to support the automatic transformation of natural language queries into relational algebra by employing appropriate natural language processing techniques and object-oriented analysis methods. The proposed logical form has the advantage that it can be mapped from natural language constructs by referring to the conceptual schema modeled by class diagrams, and can be efficiently transformed into relational algebra for query execution. We believe the whole process could offer a clear and natural framework for processing natural language queries to retrieve data from database systems.

TOWARD A FORMALIZATION OF USE CASE DIAGRAM USING Z SPECIFICATIONS

The Unified Modeling Language (UML) is an evolutionary step in the development of Object-Oriented analysis and design (OOA&D) methods that appeared in the late '80s and early '90s. UML has become a widely adopted standard in the software development industry. Various attempts have been made to formally define the syntax and semantics of the UML notations, and to represent its models in a formal notation. The purpose of these attempts is to allow UML models to be rigorously checked, and to allow formal analysis of the modeled systems. Use Case Diagram is one of the diagrams supported by UML which describe the functional requirements of the system under development, helping to identify the complete set of user requirements. This paper aims to present a tentative approach to provide the Use Case Diagram with formal semantics using Z specification language.

Management and control of information flow in CIM systems using UML and Petri nets

In this paper, we develop a systematic design methodology for control modules to manage and control the information flow among existing and new manufacturing application systems in CIM by synthesizing object-oriented modelling and net analysis (Petri net [PN]) methods. Due to the importance of objects in managing and controlling information flow, transformation rules from unified modelling language (UML) object dependencies and flows to PN were defined to extend the existing transformation rules between UML activity diagrams and PNs. The goal is to use the configurable graphic interface and the mathematical analysis methods of the PN to verify the logic correctness of the flow control mechanism and then apply the standard modelling and implementation capabilities of UML to transform the control specifications into desired computer codes with specified logic and configuration. The PN models were analysed by performing efficient algorithms that solve recursively corresponding integer programming (IP) problems to discover structural errors in the models. This design methodology was then used to build a prototype of the control module for CIM that took into account commercially available computer-aided manufacturing application systems to demonstrate its applicability.

An object-oriented analysis method for customer relationship management information systems

For the advances of Internet technologies in recent years, Electronic Commerce (EC) has gained many attentions as a major theme for enterprises to keep their competitiveness. Amongst all possibly desired endeavors for the EC, research has shown that effective management of customer relationships is a major source for keeping competitive differentiation. Therefore, it is commonly recognized as an important goal for an enterprise to promote its management of customer relationships through a prospect information system on the Internet to achieve the so-called Business-to-Customer EC. In this paper, we propose an object-oriented analysis method for the development of such a Customer Relationship Management Information System (CRMIS). The approach starts from the identification of prospect customers and their desired behaviors under preferable execution environments, and ends with the specification of system—internal objects/entities that collaborate to satisfy these behaviors and environments. The method is a use case driven approach with UML utilized and extended as its tool. To illustrate, the method is applied to an exemplified CRMTS for house agency.
