Rupali Gill1 and Jaiteg Singh2  1Assistant Professor, School of Computer Sciences, 2 Associate Professor, School of Computer Applications, Chitkara University, Punjab, India Email: rupali.gill@chitkara.edu.in Abstract: In today’s scenario, Extraction–transformation– loading (ETL) tools have become important pieces of software responsible for integrating heterogeneous information from several sources. The task of carrying out the ETL process is potentially a complex, hard and time consuming. Organisations now –a-days are concerned about vast qualities of data. The data quality is concerned with technical issues in data warehouse environment. Research in last few decades has laid more stress on data quality issues in a data warehouse ETL process. The data quality can be ensured cleaning the data prior to loading the data into a warehouse. Since the data is collected from various sources, it comes in various formats. The standardization of formats and cleaning such data becomes...

Er. Kanika Goyal1 , Amitoj Singh2  1Me Fellowship (cse), 2 Assistant Research Director, Chitkara University, Punjab, India Email: kanika.goyal@chitkara.edu.in Abstract: Sign languages commonly develop in deaf communities, that can include interpreters and friends and families of deaf people as well as people who are deaf or hard of hearing themselves. Sign Language Recognition is one of the most growing fields of research today. There are Many new techniques that have been developed recently in these fields. Here in this paper, we will propose a system for conversion of Indian sign language to text using Open CV. OpenCV designed to generate motion template images that can be used to rapidly determine where that motion occurred, how that motion occurred, and in which direction it occurred. There is also support for static gesture recognition in OpenCV which can locate hand position and define orientation (right or left) in image and create hand mask image. In this we will use...

Dinesh Kumar Sharma, Sanjay Sharma   Department of civil engineering, NITTTR, Chandigarh, India Email: Dekay_sharma@yahoo.com Abstract: Textile manufacturing industry is uses substantial amount of chemicals not only in the production processes but also in manufacturing the raw materials. Chemicals used in textile production are generally classified as commodity chemicals and speciality chemicals. Former are used in Bulk and the later are used in small quantities. Caustic Soda (Sodium Hydroxide) is one of the major chemicals which are used in large quantities for producing cotton textiles. Caustic soda results in highly alkaline waste water from the textile mills which makes the effluent toxic and poses difficulty in treatment of effluent. This study to assess the impact of caustic recovery from the mercerization plant was conducted in a cotton fabric manufacturing unit. A pilot scale single effect evaporator was used to concentrate the effluent stream from mercerization proc...

Minaxi Dassi * , Rajnish Sharma Department of Electronics and Communication, Chitkara University, Himachal Pradesh, India *Email: minaxidassi@chitkarauniversity.edu.in Abstract: A 2GHz Low Noise Amplifier (LNA) has been implemented in Cadence Spectre RF tool on UMC 0.18µm technology and is designed using a modified Cascode topology to work under reduced power supply. The input and output matching network is matched to 50Ω. After simulation it is found that at resonance frequency of 2GHz, the forward gain is 18.22dB and reverse isolation is -40.86dB.

HARPREET KAUR* , AJAYPAL SINGH and LIPIKA GUPTA Department of Electronics and Communication, Chitkara University, Himachal Pradesh-125001, India *E-mail: harpreet.kaur@chitkarauniversity.edu.in Abstract: This paper represents fixed body biased CMOS Tapered Buffer which is designed to minimize the PDP (Power Delay Product) of the circuit. CMOS Tapered Buffers are often used for driving large capacitive load at high speed. Since there are tradeoffs between performance parameters of Buffer for minimizing its PDP value and due to technology constraints on the threshold voltage of MOS; one can vary the Vth up to certain limit while keeping the VDD constant. The proposed work is helpful in designing power efficient CMOS Tapered Buffer. This is found that in proposed Buffer when Vth value for the first stage of inverter is taken between the range of (0.2VDD - 0.4 VDD), its performance gets improved in terms of power dissipation. This analysis is verified by simulating the 2-stage Tap...

Dubey1 Department of Civil Engineering, MANIT, Bhopal (MP) 462003, India 2 Department of Civil and Environmental Engineering, NITTTR, Bhopal (MP) 462002, India *Email: kkpathak1@rediffmail.com Abstract: In this study, seismic analysis of high rise building frames have been carried out considering four buildings of different geometrical plan but same area , three diaphragms and four seismic zones. In this way total 48 frames were analysed for 27 load combinations. STADD-Pro software has been used for analysis purpose. Structural analyses results are collected in terms of maximum moments in columns and beams, storey displacement, peak storey displacement which are critically analysed to quantify the effects of various parameters.

J. P. SHRIMALI1, B.L. JAIN2 , SANJAY K. SHARMA3* 1 Senior Lecturer, Vidya Bhawan Polytechnic, UDAIPUR 2 Former Associate Professor UCE, RTU, KOTA 3 Proffessor and Head Civil Engg. Dept. NITTTR Chandigarh, India * E-mail: sanjaysharmanitttr@gmail.com   Abstract: Near about 5.6% of the total tribal population of India live in “MEWAR” and “VAGGAR” region of Rajasthan state. In this region, lot of tribals are residing in the out-skirts of Banswara, Udaipur, Pratapgarh and Dungarpur districts. They prefer to live in the jungle with the nature and build their huts by using local material and local skill. It is imperative to introduce the innovative technology of the construction of rural cost-effective huts, which is based on the adoption of the local environment and constructed with the house-hold themselves without the need of the modern tools & equipment. If, we analyze the building costs and its break up, it is observed that the main components of the building are foundati...

Ravi Kumar C M1,*, Vimal Choudhary2 , K S Babu Narayan3 and D. Venkat Reddy3 1 Research Scholar, 2PG Student, 3 Professors, Department of Civil Engineering, National Institute of Technology Karnataka, Surathkal, Karnataka, India * E-mail: cmravibdt@gmail.com Abstract: The paper highlights the investigation of nonlinear axial-force and moment-curvature relationships for rectangular reinforced concrete (RC) beam and column cross sections for the reference reinforced concrete building structure considered for Probabilistic Seismic Risk Evaluation. The highly popular model namely Mander’s model is used for concrete stressstrain relationship since it is simple and effective in considering the effects of confinement. The module determines the expected behavior of a user-defined cross-section by first dividing the section into a number of parallel concrete and steel “fibers”. Then, the section forces and deformations are determined from the fiber strains and stresses using fundamental ...

Vipin Verma*, Vinay Arora  Computer Science and Engineering Department, Thapar University, Patiala-147004, Punjab, India * E-mail: vipin.vipin2008@gmail.com Abstract: Test sequence generation through code is mainly done by using some sort of a flow graph viz. Control Flow Graph (CFG), Concurrent Control Flow Graph (CCFG), Event Graph etc. Approaches that use UML also need flow graph as an intermediate representation for final test sequence generation. In the present approach, a Flow Graph for a new concept i.e. Java7 Fork/Join is constructed and hence, by traversing the graph, test sequences are generated on the basis of all path and all node coverage criteria considering interference dependence. Further, interference dependencies are also represented in the form of a directed graph to aid the analysis of Java7 fork/join programs.
