Himani Chugh  Department of Electronics and Communication Engineering, Chitkara University, Himachal Pradesh Email: Himani.chugh@chitkarauniversity.edu.in Abstract: Digital video broadcasting-terrestrial (DVB-T) was developed by the DVB Project that was first broadcast in the UK in 1997. The compressed digital audio, video and other data in Moving Picture Expert Group (MPEG) transport stream, using orthogonal frequency-division multiplexing (OFDM) modulation is transmitted by this system. In order to analyze how an MPEG transport stream at the input of a DVB-T modulator is turned into a DVB-T signal, the channel coding and modulation technique must be considered. DVB-T offers three different modulation schemes (QPSK, 16QAM, 64QAM). This paper analyzes the performance of the system for the stationary reception. The aim was to implement all the functional blocks as specified in the DVB-T specification and analyze the BER performance of the system. Thus, this paper deals with a...

Neeru Bansal1 , Naveen Kwatra2 and Varinder S Kanwar3 1 Civil Engineering Department, RIMT-MAEC, Mandi Gobindgarh 2 Civil Engineering Department, Thapar University Patiala 3 Chitkara University, HP Abstract: In the design of reinforced concrete structures, much of the attention is embarked towards calculation of the strength of basic structural elements like beams, columns and slabs. Comparatively lesser emphasis has been laid on the detailing, corresponding strength and behavior of corner joints, especially those subjected to opening moments as in the case of cantilever retaining walls, bridge abutments, channels, rectangular liquid retaining structures, beam column joints under earthquake loads. The detailing of reinforcement should be easier and simpler in order to expedite the construction process. At the same time structural member should satisfy the fundamental requirements of strength expressed in terms of controlled cracking and ductility. The result of a comprehensive ...

Masud Ur Rashid  Assistant Professor, Department of Architecture, Ahsanullah University of Science and Technology, 141-142, Tejgaon I/A, Dhaka, Bangladesh Email: masud.arch@aust.edu Abstract: It is found almost everywhere in the world that there are some taboos and beliefs related with rural settlement. There are taboos and beliefs regarding the homesteads in rural areas. Religion is one of the major factors, which guided the formations of rural houses in Bangladesh. People’s religious belief and culture is reflected over the rural settlements and homestead through the transformation process of rural housing. By the transformation of rural housing certain characteristics like building materials, utilities of space and construction technologies are changed but some elements are conserved as a part of the heritage and beliefs. As transformation is a continuous process, these conservations are carried out by some vernacular way which this paper has discussed about. DOI: 10....

Sakshi Gupta  Assistant Professor, Civil Engineering Department, Dronacharya College of Engineering, Gurgaon, Haryana, India Email: ersakshigupta18@gmail.com Abstract: This paper reviews the recent developments and present state of the application of silica fume (micro-silica) and nano-silica for sustainable development of concrete industry. This would save not only the natural resources and energy but also protect the environment with the reduction of waste material. Limited work is done on use of nano-silica and microsilica in paste, mortar and concrete and whatever work is available is highly contradictory about their influence on mechanical strength development and durability properties. Various literatures have been reviewed to understand the influence of micro and nano-silica on fresh, hardened and microstructural properties of paste, cement mortar and concrete. Taking advantage of nanostructure and microstructure characterization tools and materials, the simultaneous...

Gaurav Joshi1 , K.K. Pathak2 and Saleem Akhtar1  1 Department of Civil Engineering, UIT (RGPV), Bhopal, MP, India 2 Department of Civil and Environmental Engineering, NITTTR, Bhopal, MP, India  Email: kkpathak1@rediffmail.com Abstract: Soft storeys in a high rise building play an important role on its seismic performance. At the soft storey level, there is a discontinuity in the rigidity of the structure due to lack of infill walls or due to variation in floor height. It is this continuity which is the cause of structural failure of multi stored buildings under earthquake loads. In this study, seismic analysis of soft storey building frames have been carried out considering 3 building plans, 15 soft storeys cases and 20 load combinations. Soft storeys have been created by varying the floor heights and effect of infill is ignored. In this way, total 45 frames are analysed. STAAD.pro software has been used for analysis purpose. Results are collected in terms of max. mom...

Sandhya Sharma and Urvashi Bhat  Electronics and Communication Department, Chitkara University, Himachal Pradesh, India Email: sandhya.sharma@chitkarauniversity.edu.in Abstract: This research paper proposes a method for the compression of medical images using an efficient hybrid algorithm. The objective of this hybrid (DWT,DCT and Huffman quantization) scheme is to calculate the compression ratio, peak signal to noise ratio and mean square error by changing the DWT level and Huffman quantization factor. The goal is to achieve higher compression ratio by applying different compression thresholds for the wavelet coefficient of each DWT band and then DCT with varying Huffman quantization factor while preserving the quality of reconstructed image. First DWT and DCT is applied on individual components RGB. After applying this image is quantized using Huffman quantization to calculate probability index for each unique quantity so as to find out the unique binary code for each uni...

Sakshi Gupta National Institute of Technology, Kurukshetra 136118, Haryana, India Email:  sgupta6@ggn.amity.edu Abstract: Concrete mix design is a process based on sound technical principles for proportioning of ingredients in right quantities. This paper demonstrates the applicability of Artificial Neural Networks (ANN) Model for approximate proportioning of concrete mixes. For ANN a trained back propagation neural network is integrated in the model to learn experimental data pertaining to predict 7, 14 and 28-day compressive strength which have been loaded into a model, containing 55 concrete mixtures. The ANN model proposed is based on 5 input parameters such as cement, sand, coarse aggregate, and water and fineness modulus. The proposed concrete mix proportion design is expected to reduce the number of trials in laboratory as well as field, saves cost of material as well as labor and also saves time as it provides higher accuracy. The concrete designed is expected to hav...

In the present paper, polyvinyl pyrrolidone (PVP) capped Zn1-xEux S (0.00001≤x≤0.1) nanocrystals have been synthesized by means of a facile chemical synthesis method. Crystallography and morphology of synthesized materials have been deliberated using X-ray diffraction (XRD) and transmission electron microscope (TEM), respectively. Diffraction and electron micrograph studies reveal that the synthesized materials are zinc blende nanocrystals having average particle size ~3nm. Elemental and compositional analyses of the nanocrystals hav...
