Paper 1: Tuning of PID Controllers using Advanced Genetic Algorithm

Abstract: Proportional-Integral-Derivative (PID) controllers have been widely used in process industry for decades from small industry to high technology industry. But they still remain poorly tuned by use of conventional tuning methods. Conventional technique like Zeigler-Nichols method does not give an optimized value for PID controller parameters. In this paper, we optimize the PID controller parameter using Genetic Algorithm (GA), which is a stochastic global search method that replicates the process of evolution. Using genetic algorithm the tuning of the controller will result in the optimum controller being evaluated for the system every time. The GA is basically based on an iterative process of selection, recombination, mutation and evaluation. The performance of Advanced Genetic Algorithm (AGA) is compared with Guo Tao's Algorithm (GTA) and Elite Multi-Parent Crossover Evolutionary Optimization Algorithm (EMPCOA). AGA has a different replacement strategy as compared to EMPCOA which helps to maintain the population diversity and thus reducing the computational time which is proved by the results presented here. The effectiveness of the AGA is also verified for a system with an unstable plant. The PID controller is also tuned with different error criteria viz. Integral Time Absolute Error (ITAE), Integral Square Error (ISE) and Integral Absolute Error (IAE).

Paper 2: Removal of False Negatives in Moving Object Detection Using RGB color space

Abstract: Moving objects detection is a fundamental step in many vision based applications. Background subtraction is the typical method. Many background models have been introduced to deal with different problems. The method based on mixture of Gaussians is a good balance between accuracy and complexity, and is used frequently by many researchers. But it still cannot provide satisfied results in some cases. Video-surveillance and traffic analysis systems can be heavily improved using vision-based techniques to extract, manage and track objects in the scene. However, problems arise due to shadows. In particular, moving shadows can affect the correct localization, measurements and detection of moving objects. This work aims to present a technique for shadow detection and suppression used in a system using RGB color space for moving visual object detection and tracking. Experimental results show that the proposed approach can significantly enhance shadow suppression results and moving objects are detected.

Paper 3: Satellite Image Retrieval using Modified Block Truncation Coding and Kekre Transform Patterns

Abstract: Satellite images and Content Based Image Retrieval are interesting topics of research since years. Specifically, CBIR is on developing technologies for bridging the semantic gap that currently prevents wide-deployment of image content-based search engines. Image search engines currently in use are mostly rely on human generated data, such as text. Annotation of an image is totally depend on the person’s perception who is going to store it into database. It is time-consuming as well as error prone. Therefore search engine using text input results in various non-relevant images. To overcome drawbacks of text based image retrieval, Content based image retrieval is introduced where retrieval of images is totally depend on the features of images. Mostly, content-based methods are based on low-level descriptions, while high-level or semantic descriptions are beyond current capabilities. In this paper, we will try to implement the technique to fill this gap. This technique can eventually be extended to allow for content-based similarity type of search, to find out different query blocks from satellite image. We will fire an object as a query and most similar blocks will get retrieved. This will help out to trace particular object from large satellite image.

Paper 4: Performance Evaluation and Statistical Analysis of MANET routing Protocols for RPGM and MG

Abstract: Mobile Ad Hoc Network is a collection of mobile nodes forming temporary network. In MANET routing protocols are classified as Proactive, Reactive and Hybrid. The work presented here evaluates performance of three Reactive routing protocols such as AODV, DSR and TORA under six performance metrics such as packet delivery ratio, routing overhead, packet loss, normalized routing load, throughput and end to end delay The nodes follow two realistic mobility models such as Reference Point Group Mobility model (RPGM) and Manhattan Grid (MG) model. This work also presents the statistical analysis of AODV, DSR and TORA in Manhattan Grid (MG) model and Reference Point Group Mobility (RPGM) model in low load with low speed, average load with average speed, high load with high speed and very high load with high speed. Contribution in this work is beneficial in deciding which protocol to choose for better QoS.

Paper 5: SWiFiNet : A Task Distributed System Architecture for WSN

Abstract: WSN is a technology, straddling many application areas of this millennium. The research and practices in WSN have not mended their ways due to many unjust requirement specifications for WSN architecture. The paradox is WSN characteristics and traditional approaches for network operation are diagonally opposite. Power optimization, resource constraints and small form factor are the main characteristics of the WSN node. Taking into consideration these main characteristics, the ‘SWiFiNet’: a task distributed reusable architecture for WSN has been proposed in this paper. The focus of this architecture developed is to identify and reuse system components while preserving the sensor node characteristics. The complex network functionality is pushed onto overlay second tier devices, leaving sensor free for application development. This work demonstrates the implementation of ‘SWiFinet’ on hardware platform and network simulator using complete portability of reusable system components. Simulation and hardware results have been presented which illustrate that ‘SWiFiNet’ performs better and are application independent generic framework for WSN application development.

Paper 7: Performance of Turbo Product Code in Wimax

Abstract: IEEE 802.16 is a standard for Broadband Wireless Access (BWA) air interface. 802.16e supports mobile broadband wireless access, which is an additional feature over its predecessors, which support fixed wireless access. Binary Convolutional Turbo Coding (CTC) is used as mandatory Forward Error Correction method in 802.16e. In this paper the performance of a simple and efficient optional coding scheme namely Turbo Product Code (TPC) is proposed for 802.16e system and is compared with CTC.

Paper 8: e-Restaurant: Online Restaurant Management System for Android

Abstract: The simplicity and ease of access of a menu are the main things that facilitate ordering food in a restaurant. A Tablet menu completely revolutionizes the patron’s dining experience. Existing programs provide an app that restaurants can use to feed their menus into iOS & Android based tablets and make it easier for the diners to flip, swipe & tap through the menu. We here aim to provide the restaurants with a tablet menu that would recommend dishes based on a recommendation algorithm which has not been implemented elsewhere. In addition to this we run the app on an Android based tablet & not on an iOS based tablet which is more expensive alternative. We use a cloud-based server for storing the database which makes it inexpensive & secure.
