Analysis of Inland Wetland using Advance Remote Sensing and GIS on IRS P6 February 2005 Data of Bhopal (M.P.)
Get PDFWetlands are the transitional zones between permanently aquatic and dry terrestrial ecosystems. Wetland systems directly and indirectly support millions of people, providing goods and services to them. The use of remote sensing technology for the mapping, identification, inventory and classification of the wetlands has been a common application of satellite imagery. Remote sensing has provided a great mean to study various ecosystems of the earth including wetlands by providing cost and time effective data. For a country like India, with its vast biological and cultural diversity, a comprehensive use of remote sensing, GIS and other related technologies is of great use in their conservation.DOI: http://dx.doi.org/10.11591/ij-ict.v1i1.54
A New Proxy-Protected Signature Scheme Based on DLP
Get PDFDuring electronic communication, proxy signature helps the signer to sign message on behalf of the original signer. This type of signature scheme is used when the signatory is not available to sign this document. In this paper, we propose a new protected proxy signature scheme. In the proposed scheme, the proxy signer can sign message on behalf of the original signer with the different type of public key. The proposed scheme satis es unforgeability, undeniability, non-transferability and distinguishability properties which are the most important security requirements for a proxy signature.DOI: http://dx.doi.org/10.11591/ij-ict.v1i2.147
Measuring Security in Requirements Engineering
Get PDFThe aim of this paper is to measure the security and related verification method in requirements engineering (RE). There are a few existing approaches to measure RE performance like IEEE Software Requirements Specification (SRS) and Security Quality Requirements Engineering (SQUARE). However, these existing approaches have some limitations such as lack of flexibility and require long implementation period. In order to address these issues, this paper intends to propose a new set of tools. First is the Effective Security Check List (ESCL), which is a check list with security questions that should be considered for measuring security. Secondly, the Traceability Matrix(TM), which is a two dimensional matrix to measure security during RE. Thirdly, Requirement Engineering Assessment Document (READ), which is a tool containing all statistical information about security performance during RE. The combination of presented approaches had been implemented in a case study. The outcome results are encouraging and illustrated integrated outcomes within existing RE model. The security level had also been properly measured.DOI: http://dx.doi.org/10.11591/ij-ict.v1i2.69
Application of MIMO Technology to Systems Beyond 3G
Get PDFThe evolution of mobile Broadband over the years has been phenomenal and worthy of attention by academics, researchers, the corporate world and users alike. From the days of the First Generation (1G) through the Third Generation (3G) communication systems, the evolution has continued and has been largely influenced by an ever increasing demand for improved services and greater capacity evident in higher data rates, wider and improved coverage, improved spectral efficiency and lower latency. In response to these demands and to address some of the loopholes of the 3G networks, the 3rd Generation Partnership defined the Long Term Evolution (LTE). LTE though an evolving technology is widely accepted due to its unprecedented promised performance. As the evolution continues, the design of the ‘LTE-Advanced’ is already in progress and has been tagged different names such as the ‘4G’ and ‘Beyond 3G’ (B3G). The main backbones behind these evolutions are technological developments in the underlying mobile radio technology such as multicarrier technology (majorly OFDMA), multiple-antenna technology (MIMO) and the application of packet-switching to the radio-interface through improvements in techniques like adaptive scheduling in both the frequency and spatial dimensions, link adaptation of modulation and code-rate and several modes of fast channel state reporting. This paper is set to present the multiple antenna technology and how it contributes to the delivery of the expectations of the wireless communication systems beyond 3GDOI: http://dx.doi.org/10.11591/ij-ict.v1i2.148
Synthesizing the Whole View of a Large-Scale Object
Get PDFThis paper presents the effective method for the whole view synthesizing of the large-scale object. This synthesizing method is developed based on the image registration approach. The foreground object is extracted from each image by color image processing. The information of the feature points of an object is obtained from a foreground image and establishing the correspondence among views. The translation and rotation parameters between two successive images are estimated by the computed camera calibration parameters. The second image is transformed by using these parameters and combine to first image. The integrated image is obtained by combining the overlapping parts of these images. A whole view of the large scale object is reconstructed image by applying the above process successively. Preliminary investigations with sampled images of a real scene have been done to confirm the effectiveness of the proposed method.DOI: http://dx.doi.org/10.11591/ij-ict.v1i1.59
