Taking forward the digital India mission it is essential to design and validate intuitive e-commerce shopping sites before implementation of template so that users can do shopping easily, without any need of special training. We have achieved this in several steps. Documented mental model and behavioral patterns while interacting with shopping site. We have mapped existing shopping site with mental...
Supply chain management issues are identified in this paper. We have also identified critical, moderate and important issues in international and national oil companies. Also we have studied the impact of Knowledge Management application/ use on Indian public sector oil companies.
Recently, smart phones have become popular in research applications because of improved performance. Several engineering and non-engineering applications are implemented in android operating system. One of the promising application area might be antenna engineering domain by developing apps in existing smart phones that can accurately determine vital parameters in antenna design. The objective of...
The analysis of frames transmitted in 802.11a/n/ac demonstrates performance degradation when many devices need to transfer large data volumes. Furthermore, despite the frame aggregation implemented by newer standards (802.11n/ac), the same performance degradation was observed. The experiments in this research show that, regardless of the standard, it is possible to apply management techniques in aggregated...
Magnitude of urban population and unplanned development of cities have led to road traffic congestion in major cities and added increasing pressure on overall road transport and road related infrastructure. Nowadays, intelligent transportation systems such as Vehicular Ad Hoc Networks (VANET) are used for distributed road traffic. VANET is a wireless network that gathers complex and randomly generated...
Currently, the FFT is used in different areas, starting from identification of frequency on mechanical vibration to image enhancement. Real-time computation by interpret the acquired data can be easily possible by Fast Fourier Transform (FFT). The best with an efficient algorithm is FFT so it is the foundation for analyzing, monitoring, and controlling various systems. Many applications like digital...
Tourism industry is one of the most rapidly growing industry in the world. It has major contribution to the economy of the country. Through literature survey, it has been observed that there is much scope of improvement in this sector. This paper presents the tourism recommendation system which is built using the concept of web mashup which extracts data from multiple websites. This extracted data...
One of the recent trends in wireless networking is Wireless sensor network (WSN), in this type of network tiny electronic device sensors organized in an environment where human intervention is problematic. In WSN, various sensors organized in a sensing environment works together in coordination to monitor and control the physical property of an environment. To efficiently perform the given task while...
In this article, a high contrast all-optical XOR gate is proposed using photonic crystal based T-shaped waveguide. Out of phase inputs allow the gate to produce a quite low intensity at the output to represent logic ‘0’ which results in higher contrast ratio of 45.52 dB. The calculated bit rate of the proposed gate is 7.375 Tbps which has made it suitable to work in high speed optical computing and...
The multiple packets reception by a station network interface in WDM networks is explored in this study. Especially, we assume a WDM LAN of passive star topology which uses the MCA for the control information exchange. The station network interface includes three tunable receivers in order to face the packets rejection at destination due to the receiver conflicts. An efficient WDMA protocol is adopted...
Image enhancement is one of the important part of image processing. Proposed research presents an image enhancement method, named CLAHE-HWT derived from its existing CLAHE-DWT, which combines the Contrast Limited Adaptive Histogram Equalization (CLAHE) with Hybrid Wavelet Transform Type I (HWT I) wavelets. The method includes, the original image is decomposed into low-frequency and high-frequency...
Textual passwords are used worldwide due to its easy implementation and less time required for authentication. But these passwords are vulnerable to dictionary attack, brute force attack, man in middle attack, etc. It is also highly prone to keylogging and shoulder surfing attack. Hence new authentication systems such as biometric based and token based system were introduced. But they have their own...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
In this paper, a small size and low cost antenna is proposed suitable for Ultra Wide Band (UWB) short-range communication applications having reduced interference for multiband operation at WiMax, C-band and X-band systems. The designed antenna covers the ultra wide band range (3.1 GHz to 10.6 GHz) and has Voltage standing wave ratio less than 2 and the return loss is less than −10db, reducing the...
Fiber lasers and fiber amplifiers are of important use in optical communication systems. While there is weak bridge between experimental and theoretical research, a comparative investigation of the design experiment, programing and simulations analysis of EDFA of double pass is performed using three different categories. Experiment, Optisys and Matlab types are used to investigate and analyses the...
One of the primary aims of Optimization is to hunt the best entity from the available set of choice without explicitly assessing them. A new design, efficient outcome and cost effective solution is the outcome of optimization. Radio network planning is the basic seed required for configuring the base station parameters to attain the desired Quality of Service. The tuning of the radio network parameters...
The criteria for performance improvement for a WDM network of passive star topology that occupies a separate control wavelength is studied in this paper. Especially, a WDMA algorithm is adopted that provides additional transmission capabilities over the data channels, aiming to improve the performance. The analytical model provided is based on Poisson statistics and derives the mathematical formulas...
