Denoising of Transient VEP Signals Using Wavelet Transform
R. Sivakumar,B. Hema,Pooja Karir,N. Nithyaklyani
Journal of Engineering and Applied Sciences , 2012,
Abstract: Transient Visual Evoked Potential (TVEP) is an important diagnostic test for specific ophthalmologic and neurological disorders. TVEP investigation is focused on the dominant peaks N75, P100, N145, a negative deflection followed by a positive deflection and then a negative deflection. Quantification of these latency changes can contribute to the detection of possible abnormalities. We have applied the wavelet denoising method to 100 pre-recorded signals using all the available wavelets in MATLAB wavelet toolbox to analyze the peaks (P100, N75 and N145). From the results it is clear that the positive peak is clearer in the denoised version of the signal using the wavelets Sym5 and Bior3.5. As opposed to the previous studies however our study clearly shows that the output using the former wavelet effectively brings out the P100 when compared to the latter. The first negative peak was clear in the denoised version of the signal using the wavelets Bior5.5 Bior6.8 and coif4. The second negative peak N145 was clear using all the above wavelets. In conclusion all the three peaks were fairly clear in the denoised output using the wavelet sym7. This would greatly help the medical practitioners. All the previous studies concentrated on the P100 only. Using the proposed method all three peaks could be analyzed in detail.

Shailender Singh, Pooja Jain
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.815213
Abstract: A vital role is played by FDI (Foreign Direct Investment) in enhancing the growth and economic status of the country. Most of the countries in the developing phase depend on FDI to foster their economy as they were facing the scarcity of hard cash for their development process. High growth performance experienced by Taiwan economy largely relies on the FDI; to attract the foreign capital inflows the Taiwan government work on many policies. But the most important factors which influence and attract the foreign capital inflows are in academic debate. On the basis of macroeconomic theory knowledge, this research paper will shed light on the econometric analysis on the data of Taiwans total foreign direct investment and factors influencing it, which contains exchange rate, inflation rate, Taiwan stock exchange index, import, and business income tax during the years of 1998 to 2013.
Effect of Non-Homogeneity on Thermally Induced Vibration of Orthotropic Visco-Elastic Rectangular Plate of Linearly Varying Thickness  [PDF]
Arun Kumar Gupta, Pooja Singhal
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.14043
Abstract: The analysis presented here is to study the effect of non-homogeneity on thermally induced vibration of orthotropic visco-elastic rectangular plate of linearly varying thickness. Thermal vibrational behavior of non-homogeneous rectangular plates of variable thickness having clamped boundary conditions on all the four edges is studied. For non–homogeneity of the plate material, density is assumed to vary linearly in one direction. Using the method of separation of variables, the governing differential equation is solved. An approximate but quite convenient frequency equation is derived by using Rayleigh-Ritz technique with a two-term deflection function. Time period and deflection at different points for the first two modes of vibration are calculated for various values of temperature gradients, non- homogeneity constant, taper constant and aspect ratio. Comparison studies have been carried out with non-homogeneous visco-elastic rectangular plate to establish the accuracy and versatility.

Arun Kumar Gupta, Pooja Singhal
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.16060
Abstract: A simple model presented here is to study the thermal effect on vibration of non-homogeneous orthotropic visco-elastic rectangular plate of parabolically varying thickness having clamped boundary conditions on all the four edges. For non-homogeneity of the plate material, density is assumed to vary linearly in one direction. Using the separation of variables method, the governing differential equation has been solved for vibration of non-homogeneous orthotropic viscoelastic rectangular plate. An approximate frequency equation is derived by using Rayleigh-Ritz technique with a two-term deflection function. Results are calculated for time period and deflection at different points, for the first two modes of vibration, for various values of temperature gradients, non-homogeneity constant, taper constant and aspect ratio and shown by graphs.

International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: The increasing demand for more computing power and data storage capacity in many fields of business, research, engineering, medical and science has raised the emergence of Grid Computing. Grid computing facilitates the environment where computers are interconnected with each other in such a manner that for making the execution faster of their tasks they can utilize the unused processing power of other idle systems. The applications of grid demand the secure access to the computational resources in the distributed environment. The secure and uniform access to resources is provided by Grid Middleware. In this paper, I have presented some of the middleware and Toolkits having some advantages and disadvantages.
SYSTEM IDENTIFICATION AND CONTROL IN ELECTRICAL ENGINEERING USING NEURAL NETWORKS
POOJA KHATRI
Indian Streams Research Journal , 2013,
Abstract: Neural networks offer an alternative approach both for identification and control of nonlinear processes in process engineering. The lack of software tools for the design of controllers based on neural network models is particularly pronounced in this field. SIMULINK is properly a widely used graphical code development environment which allows system-level developers to perform rapid prototyping and testing. Such graphical based programming environment involves block-based code development and offers a more intuitive approach to modeling and control task in a great variety of engineering disciplines. In this paper a review of SIMULINK based Neural Tool has been done for analysis and design of multivariable neural based control systems. Application areas of ANNs include system identification and control (vehicle control, process control), game-playing and decision making (backgammon, chess, racing), pattern recognition (radar systems, face identification, object recognition), sequence recognition (gesture, speech, handwritten text recognition), medical diagnosis, financial applications,knowledge discovery in databases,visualization and filtering.

Pooja Walia
Indian Streams Research Journal , 2012,
Abstract: The present study was conducted to examine the relationship of mathematical creativity with achievement and differences between boys and girls with regard to their mathematical creativity (along with its dimensions) and achievement. Simple random sampling was used to select the participants. Participants (N= 180, boys = 99 and girls = 81) completed creativity test. Mathematical creativity was measured using the Creative Ability in Mathematics Test developed by Balka (1974). Pearson's Product Moment Correlation analysis indicated that mathematical creativity (along with its dimensions) is related to achievement in mathematics of eighth grade students. No significant difference was found between boys and girls with regard to their achievement and mathematical creativity (along with its dimensions). However, girls were found better than boys on one dimension of mathematical creativity i.e. flexibility.
THE JOURNEY OF EVALUATION SYSTEM FROM ANCIENT GURUKUL TO MODERN EDUCATION SYSTEM
POOJA SINGHAL
Indian Streams Research Journal , 2012,
Abstract: Education aims at making children capable of becoming responsible, productive and useful members of society. Knowledge, skills and attitudes are built through learning experiences and opportunities created for learners in schools. The education system in vogue in a country reflects the ethos, aspirations and expectations of a particular society. As aspirations and expectations of each generation vary with time, constant review of curriculum and evaluation system becomes an essential exercise. Evaluation is very important component of the education system. Reforms in the examination system are often recommended, sometimes discussed and rarely implemented. Introduction of Continuous and Comprehensive Evaluation (CCE) is one of such reforms which have undergone a painful journey. The need for introducing CCE in schools in an effective and systematic manner has been felt for a long time. The present paper discusses the journey of evaluation system from our Ancient Gurukul system in form of oral examination to the implementation of Continuous and Comprehensive Evaluation of Modern Education System in Indian Perspective. The paper reflects the rationale behind replacing our traditional examination system with the concept of Continuous and Comprehensive Evaluation (CCE) and its relevance in school education over the traditional examination system. Further this paper also highlight several problems associated with the execution of Continuous and Comprehensive Evaluation and suggests few remedial measures for its smooth execution.

POOJA SINGHAL
Indian Streams Research Journal , 2013,
Abstract: The teacher in the emerging Indian society has a very pivotal role in the social reconstruction of wisdom, knowledge and experiences of one generation to another. Now with the increasing complexity of modern times, education faces ever-changing new demands and mostly teachers have to bear all the burden of all the changes. In order to equip the students and teachers to face the emerging challenges of 21st century there is a need to introduce educational technology in the teaching learning process at all the levels of education. The present paper emphasized on the rationale to use education technology in 21st century and how it has enabled the teachers to present the art of teaching in a new fashion. Further the paper highlighted certain limitations and hurdles that are experienced by the teachers, students and educational institutes while using educational technology in the teaching-learning process. The authors aver that neither because of such limitations the importance of educational technology can be overlooked nor it can completely replace the role of a teacher. Rather they both should go hand in hand to make teaching-learning process effective and fruitful.
Impact Of Mobility and Transmission Range On The Performance of Backoff Algorithms For IEEE 802.11-Based Multi-hop Mobile Ad hoc Networks
Pooja Saini
International Journal of Advancements in Technology , 2010,
Abstract: In IEEE 802.11 Wireless Local Area Networks (WLANs), network nodes experiencing collisions on the shared channel need to backoff for a random period of time, which is uniformly selected from the Contention Window (CW). This contention window is dynamically controlled by the Backoff algorithm. First step to design a an efficient backoff algorithm for multi-hop ad hoc network is to analysis of the existing backoff algorithms in multi-hop ad hoc networks. Thus, in this paper, we considered two important multi-hop adhoc network scenarios: (a) Node Mobility Scenario and (b) Transmission Range Scenario and analyze and evaluate both the impact of mobility (i.e. node speed) and the impact of transmission range of nodes on the performance of various backoff algorithms
