Requirements Elicitation Techniques: Comparative Study

Authors: Omar Isam Al Mrayat, Norita Md Norwawi, Nurlida Basir

Abstract- — Over the years, software development failures is really a burning issue, might be ascribed to quite a number of attributes, of which, no-compliance of users requirements and using the non suitable technique to elicit user requirements are considered foremost. In order to address this issue and to facilitate system designers, this study had filtered and compared user requirements elicitation technique, based on principles of requirements engineering. This comparative study facilitates developers to build systems based on success stories, making use of a optimistic perspective for achieving a foreseeable future. This paper is aimed at enhancing processes of choosing a suitable technique to elicit user requirements; this is crucial to determine the requirements of the user, as it enables much better software development and does not waste resources unnecessarily. Basically, this study will complement the present approaches, by representing a optimistic and potential factor for every single method in requirements engineering, which results in much better user needs, and identifies novel and distinctive specifications.

Keywords- Requirements Engineering, Requirements Elicitation Techniques, Conversational methods, Observational methods, Analytic methods, Synthetic methods.

Binary Morphology with Image Compression and Cryptography

Authors: Ponshankar B, Swaranambigai.R

Abstract - Binary Image processing is extremely useful in various areas, such as object recognition, tracking, motion detection, machine intelligence, image analysis, understanding video processing, computer vision, and identification and authentication systems. Binary image processing (BIP) has been commonly implemented using processors such as CPU or DSP. However, it is inefficient and difficult to use such processors for binary image processing. High-speed implementation of binary image processing operations can be efficiently realized by using chips specialized for binary image processing. Mathematical morphology (MM) is a nonlinear image processing framework used to manipulate or analyze the shape of functions or objects. Mathematical morphology(MM) is set theory-based methods of image analysis and plays an important role in many digital image processing algorithms and applications, e.g., noise filtering, object extraction, analysis or pattern recognition. The methods, originally developed for binary images, were soon extended and now apply to many different image representations. Real-time image processing systems have constraints on speed or hardware resources. In addition, in embedded or mobile applications, this system consumes low power and low memory. The cryptography involves efficient algorithms related to encryption and decryption.

Keywords - Binary image processing (BIP), Mathematical morphology (MM), RSA algorithm, structuring elements, encryption and decryption

Optimization of Surface Roughness using Response Surface Methodology for EN31 Tool Steel EDM Machining

Authors: Singaram Lakshmanan, Prakash Chinnakutti, Mahesh Kumar Namballa

The present work demonstrates the optimization process of surface roughness of electrical discharge machining (EDM) by using Response Surface Methodology (RSM). The work piece material was EN31 tool steel. The pulse on time, pulse off time, pulse current and voltage were the control parameters of EDM. RSM method was used to design the experiment using rotatable central composite design as this is the most widely used experimental design for modeling a second–order response surface. The surface roughness parameters like, root mean square (Rq), skewness (Rsk), kurtosis (Rku) and mean line peak spacing (RSm) are considered for modeling. The process has been successfully modeled using response surface methodology (RSM) and model adequacy checking is also carried out. The secondorder response models have been validated with analysis of variance.

Planning of UPFC for the Power System Transient Analysis

Authors: G Kalidas Babu, S Rajesh Kumar, A Santosh Kumar

Abstract- Improvement in semiconductor technologies gave a new concept of Flexible AC Transmission system (FACTS) which brought radical changes in the power system operation, control and also for controlling power and enhancing the usable capacity of existing transmission lines by controlling both active and reactive powers. The Unified Power Flow Controller (UPFC) is devised for the real time control and dynamic compensation of ac transmission systems providing multifunctional flexibility required to solve many of problems facing the power delivery industry. The aim of this paper is to model UPFC and its control circuit using SIMULINK and to analyze the control circuit for effective power flow control using three different control schemes – phase angle control, cross coupling control and generalized control. After modelling UPFC, a single machine connected to a transmission line along with UPFC has been considered to study its performance. In brief, it is the study of Unified Power Flow Controller and its role in damping power oscillations and power swings to improve system performance.

Satellite Imagery Applications of Urban Road Inventory, Traffic Flow Attributes, and Road Capacity Assessment

Authors: W. Uddin, A. Ahmed, M.S. Ali

Abstract- Road inventory and traffic volume demand maps are the most important elements of a working traffic management system. In some countries these up-to-date road inventory data are not available and 24-hour traffic counts are not frequently collected due to lack of funds or difficult to access remote places. The authors discuss a geospatial methodology using 0.6m high resolution satellite imagery that was successfully implemented for creating road network planimetrics for road inventory, traffic flow attributes, and traffic volume demand maps. The capacity analysis results show that the analyzed urban road sections were mostly at level-of-service C, D, or E. The traffic demand volume data can be used to calculate congestion costs and recommend traffic management priorities.

Keywords- Capacity, geospatial analysis, inventory, road, satellite imagery, traffic flow, volume.

Investigation of Neotectonics along Hazara Kashmir Syntaxis through Remote Sensing and GIS Analysis

Abstract- The fatal earthquake of October 8, 2005 occured in Pakistani Himalayas and specifically within the Hazara Kashmir Syntaxis (HKS). The HKS is an active tectonic structure formed as a result of India-Eurasia collision. The unrelenting competition between tectonics, climate and erosional factors has created a very distinctive topography and thrust geometries in HKS. The aim is to constrain neotectonics and related active surface deformation based on semi-automated Digital Elevation Model derived morphometric parameters. The Shuttle Radar Topography Mission DEM with a spatial resolution of 90 m has been engaged for the generation of Hack gradient, steepness, concavity and relative uplift rate maps for the geomorphological analysis. The other surface dynamic indices such as drainage density, lineament density along with their rose diagrams were also generated automatically. A detailed stream profile analysis, lineament and drainage density, relative relief (incision map) revealed that the results obtained for the relative uplift rates and other geomorphic indices are consistent with the neotectonic activity along HKS. The relative uplift rates are higher in the NNE (2.35 mm/yr.) as compared to lower (0.01 mm/yr.) in the SSW part of study area. The steepness index and Hack gradients show more steepened regions and steep slopes NNE of HKS than SSW that is indicative of neotectonic activity. These results suggest tectonic control over the drainage network and the topography in the study area. The geomorphic indices and relative uplift rate maps also shows that the NNE is more deformed and uplifted region than the SSW. The inhomogeneous spatial distribution of variable relative uplift rates is a clear indication of complexity and severity of surface deformation in the HKS.

Keywords- SRTM DEM, drainage network, neotectonics, Hazara Kashmir Syntaxis and Relative uplift rates.
