This paper presents investigative study on the life transitions, problems faced by a woman as she chooses engineering as career, and thus the preferences, priorities, expectations and apprehensions. Around 200 women comprising of student community, faculties, and working professionals were surveyed and the responses are recorded herein. Lots of positives have resulted as self satisfaction is what drives the women engineers while money being not a major concern. Social discrimination is still found to be a main issue. Requirement for upliftment and consideration of women engineers as part of mainstream workforce for the development, setting aside the gender bias is proposed. © 2012 IEEE.

The DW consists of huge and complex set of data. Maintaining its quality is thus a matter of concern. The metrics are used to measure the quality factor of data warehouse. Several data model metrics of data warehouse have been proposed and validated in the literature to measure its quality attributes. There are two ways to validate the metrics. One is the formal validation and another is empirical validation. Our focus of study is on formal validation of metrics. Here in this paper, two formal frameworks have been surveyed for metrics validation namely; Briand's framework and Zuse's framework. Further, formal validation is illustrated with the help of Briand's framework and Zuse's framework by taking an example of each. Finally, both the formal frameworks have been compared and found easily understandable for validating the metrics formally. © 2014 IEEE.

Development of intelligent transportation system is the need of all the developing countries where urbanization and industrialization is rapidly growing. VANETs are being used as a tool for improving road safety by alarming the drivers about accidents occurred ahead of them or for providing internet access to the passengers via gateways along the road. Due to highly dynamic nature of nodes in VANETs, designing a routing protocol for VANET is quite challenging compared to MANET environment. Researchers have suggested several routing mechanism for VANETs. Few routing decision are based on topology based selection whereas others have considered different parameters like location information of nodes, traffic lights etc. As no benchmarking scheme is available for choosing a routing protocol in VANET, this article gives an insight on how to choose a routing protocol depends on varying condition of traffic. Three popular protocols AODV, DSR and LAR have been chosen for analysis on varying traffic environment. All the three protocols have been critically tested for different metrics such as Throughput, Packet Delivery Ratio and Routing overhead during the simulation. Simulation is carried out with the help of open-source simulation tools NS2, a network simulator, and SUMO, a traffic simulator. © 2015 IEEE.

In this paper, we have proposed a new method to predict the boxoffice collections for Bollywood movies using the online blogs written by the people.Since,the opinions given by people in their blogs are not adequate enough to decide the fate of a Bollywood movie and there are certain otherfactors also that contribute to a Bollywood movie's success or failure at box office, therefore the prediction of box office collections should also include these factors in addition to the opinions. Some of these factors which influence Boxoffice collection are the actors present in the movie, the banner under which the movie is produced, type of promotions, songs ratings obtained pre-release of the movie and its time of release. In our method we have taken into consideration all of these factors. First of all we have prepared a database taking into account the above mentioned variables and populated it with the data of the 334 Bollywood movies released within the year 2007-2013. This database is then fed into the data mining tool XLMiner® to predict the box office collections using multiple linear regression algorithm. Next, in order to determine the weight of the opinion representing the blogs, a crawler in Java® has been developed to extract the comments posted on Times of India website and altogether, 11,990 comments have been extracted. Then the extracted comments are tagged using an online tagger named NLP Tagger.The adjectives are extracted from the tagged file and a dictionary containing seed words of movie domain has been created from WordNet® to determine the polarity of words extracted. The concept of tf-idf is then used to generate the opinion score. After this the weight is incorporated to the previously prepared database. The regression algorithm is also implemented in Java® which takes the above mentioned variables as input and predicts the boxoffice collection of the movie as output.We have verified our proposed method on two Bollywood movies released in 2013 and two Bollywood movies released in 2015. The developed system has an accuracy of 89.86136%. © 2015 CRL Publishing Ltd.

A slot loaded micro strip antenna with an aperture coupled feed is proposed. The basic radiator is a square patch with a 'dual loop' shaped slot cut into the patch area. The usable bandwidth of the slotted antenna is 840 MHz (2.37-3.21 GHz) which is appropriate for WLAN application in the 2.4-2.484 GHz band and WiMax application in 2.5-2.69 GHz band. The antenna is designed, simulated and optimized for wideband RF performance using HFSS. The simulated 2:1 VSWR bandwidth of the antenna is 30.10% with respect to the mid-band frequency of 2.79 GHz. The proposed antenna gain is greater than 6.5 dBi in the WLAN band and more than 7.3 dBi in the WiMax band. The antenna presents a patch size reduction of 44% when compared to a conventional square micro strip patch antenna. The antenna has an overall dimension of 70 x 70 x 11.58 mm3. © 2015 IEEE.

In this paper, we have evaluated performance of various routing protocols for Vehicular Ad Hoc Network (VANET) in different traffic patterns with real vehicular traces. The vehicular movements are based on intelligent driver model with road intersection. Our objectives is to provide a comparative analysis among various ad hoc routing protocols based on packet delivery ratio. Routing protocols are LAR1, AODV and DSR protocols. The traffic patterns categorize as sparse, moderate and dense based on the number of nodes. The results show that LAR1 protocol outperform others. The maximum packet delivery ratio obtained is 99.52% in the sparsely populated network. We have used Glomosim 2.03 and VANETMobiSim simulator for our analysis. © 2015 IEEE.

Vehicular ad-hoc network (VANET) is an important technology for future development of intelligent transportation systems. Due to the highly-dynamic nature of vehicular nodes, network topology changes very frequently which complicate the routing of data packets. A number of routing protocols have been developed by various researchers. Hop count is a key parameter in evaluating the performance of a routing protocol. Number of hops required in directional routing protocols is more in comparison to other routing protocols. For a city vehicular traffic scenario we propose an improved direction-based location aided routing (D-LAR) protocol that we call distance and direction-based location aided routing (DD-LAR) protocol. A mathematical model for DD-LAR protocol has been developed to examine its performance on path duration and hop count metric. Simulations have been done in MATLAB and from the results, it can be seen that DD-LAR routing protocol shows significant performance improvement over D-LAR and LAR in terms of reducing the hop count and maximising the path duration. © Copyright 2016 Inderscience Enterprises Ltd.

A compact single feed circularly polarized micro strip antenna with cross shaped slits is proposed for GNSS (Global Navigation Satellite System) applications. In this paper, four cross shaped slits are embedded at the corners of a cross slot loaded square patch thus improving axial ratio bandwidth. In addition, five cross slots are cut on the ground plane for achieving better compactness and superior return loss. The proposed structure is about 60% compact in size when compared with the conventional micro strip antenna design. It has also been observed that the resonant frequency is highly dependent on length and width of the centred cross slot and embedded corner cross slits. The 3-dB axial ratio bandwidth achieved is 2.2%. © 2014 IEEE.
