Urban air pollution is a global problem having considerable impact over health and vegetation. Green belts are recognized as effective tools for alleviation of air pollution. The present study was conducted to calculate the impact of air pollution over biochemical parameters of selected tree species at different locations of the holy city of Kurukshetra, Haryana. The ambient air quality status was monitored at 7 traffic intersections of the city for three consecutive years and the concentration of major air pollutants (SO2, NO2 and SPM) was measured. Suspended particulate matter concentration exceeded the prescribed limits of CPCB at all the locations. Air Pollution Tolerance Index (APTI) of 10 common tree species was evaluated by determining biochemical parameters. The Anticipated Performance Index (API) of these plant species was also calculated by considering their APTI values together with other socio-economic and biological parameters. The most suitable plant species for green belt development in urban areas were identified and recommended. Mangifera indica and Eucalyptus tereticornis were classified in to ‘best’ category whereas, Ficus benghalensis and Ficus religiosa were identified as ‘good’ performers. The plant species identified are recommended for long-term management of air pollution.

Safety of passengers in elevator is a critical issue in case of power failure. The purpose of built system are designed to supply power to emergency evacuation system and exist passenger when main power supply has fails. Currently power storage methods are used by charging battery during operation. While on other hand, safety measures employ separate setup thanonce required normal operation. The concept of merging two separate ideologies into one, i.e storing power during the routine operation and utilizing the stored power in case of power failure. This can be achieved by storing energy in a battery bank from the normal supply given to elevator for its working. When a power cut is detected ,which is done using a microcontroller by constantly checking the signal reaching to drive the elevator car, the stored power is utilized to make theelevator reach the nearest corresponding floor and open the doors. Hence the need to equip the elevator with separate safety devices can be fulfilled by reuse of energy, thus eliminating the extra efforts and capital required for safety devices.

Speech is produced by exciting the vocal tract system by an excitation source. The excitation is significant at the instants of glottal closure. These instants of significant excitation are called Epochs. Epochs play a significant role in speech processing and is used are used in many applications. There are different methods for extraction of epochs from speech signal. In this paper we have discussed and compared three methods namely Linear Prediction Based (LP Based) Method, Group Delay Based (GD Based) Method and Zero Frequency Filtering (ZFF) Method. LP-Based method and GD-Based method depends on characteristics of both the excitation source and vocal tract system. ZFF method is based on the impulse nature of the excitation signal and is not affected by the characteristics of the vocal tract system. The ZFF method gives more accurate and reliable results compared to the first two methods.

Pages: 293 - 298
Traffic congestion has become a major problem nowadays. Traffic congestion especially occurs in metropolitan cities. Increased air pollution, noise pollution, accidents, delay in travel time etc are some of the problems that are faced by people living in these mega cities. Traffic jams have severely impacted the lives of citizens. The traditional traffic lights deployed in cities are not sufficient to meet the demands of an over-growing city since these traffic lights have specific pre-determined time intervals for changing from red phase to green phase. In this regard several attempts were made to automate the traffic lights based on the density of vehicles on the road. Some authors suggested the use of sensors to determine vehicle count while several others suggested the use of video cameras to capture moving vehicles and perform preprocessing on the videos to obtain vehicle count. This paper summarizes a review on the various methods that were used for the development of an intelligent traffic management system. A detailed comparison of all the methods is provided in this paper along with the pros and cons of every method.

Multilevel inverters are very popular and have many applications in electric utility and for industrial drivers. As the number of levels in multilevel inverter increases, THD decreases accordingly. The paper compares three different topologies of inverters (Diode clamped inverter, Flying capacitor inverter and Cascaded H-bridge inverter). The comparison is done with respect to cost, power losses and THD. MOSFETs and IGBTs are used a switching devices for analysis. Tradeoff between the power losses and cost is also discussed in this paper. To select a multilevel inverter is a tradeoff between cost, complexity, losses and THD. The most important part is to decide which one is more important.

A college campus may be very large or may have many buildings. Also, every year hundreds of students take admission to a college and new staff are recruited every year. In a college, new courses maybe started and some departments may be relocated inside the campus. There does not exist an efficient system to inform one about the events scheduled for the year. Also, in case of relocation or postponement of an event, participants and delegates attending the event need to be notified of the same. Colleges have different seminars and conferences, the college cultural fest, tech fest events in which teachers and students from different colleges may wish to be a part of. But one may faces problems like finding the location, which route should be taken and about updates in an event. To overcome these problems we have created a Global Positioning System (GPS) based Android App known as “College guide navigation†which will give proper notification of the upcoming events to the users. It will also help user to navigate to the event venue from his current location.

The contrast enhancement technique is specifically used to adjust the global brightness and contrast of images. Malicious users may perform local contrast enhancement for creating realistic composite images. In project, novel Approach for Contrast Enhancement Detection is used to detect the contrast enhancement in the images for verifying the originality and authenticity of the images. The new methodology involves two novel algorithms to detect the manipulations of contrast enhancement in digital images. One of the algorithms focuses on the detection of global contrast enhancement applied to the JPEG-compressed images, as these are widespread in real applications. The histogram artifacts incurred by the JPEG compression and also the pixel value mappings are analyzed theoretically and then distinguished by identifying the zero-height gap bins. Another algorithm helps to identify the composite image which is created by enforcing contrast adjustment on either single source region or both source regions. Then the positions of detected block wise peak/gap bins are clustered to recognize the contrast enhancement mappings which are applied to different source regions. At last, the consistency between regional artifacts is checked for discovering the image forgeries and also for locating the composition boundary. Matlab tool is used for evaluating the performance of these two algorithms on various images. The extensive experiment also verified the effectiveness and efficacy of the new methodology.
