COMPARATIVE ANALYSIS OF 64 CHANNEL IS-OWC SYSTEM THROUGH CHIRPED, AMI AND DPSK MODULATION TECHNIQUES by Ravneet Kaur

Abstract

Inter-satellite Optical Wireless communication has been a hot research area, where modulation techniques are useful due to its enormous advantages and applications in satellite network. While FSO systems are used for transmission of data and signals, but due to turbulences and pointing errors, they are less used.IS-OWC system is preferred due to high bandwidth, free from turbulences, immunity to RF and microwave frequencies. IS-OWC system while implemented with WDM systems provides high capacity, less bit errors and huge security. The current work carried out using Optisystem software demonstrates IS-OWC system with the modulation techniques which is the best challenge for future communication system because it has the resistance to dispersion, four wave-mixing and improved narrow band filtering. Modulation techniques have been useful to provide integration with WDM systems as WDM multiplexer allows 64 multliplexers to multiplex signals using EDFA and OWC channel with the use of Loop Control. This technique increases the efficiency of the system. In this thesiswork, Ultra-high capacity IS-OWC systems having 64 channels are designed using modulation techniques at bit rates of 10, 20 and 40 Gbps.Here the proposed IS-OWC system is implemented using Chirped modulation, Alternate mark inversion and Differential phase keying modulation technique. The results of the proposed system is measured at different bit rates and distances and thus compared at the range of 750 nm. Performance analysis in terms of Q-Factor, Optical Spectrum Analyzer, BER and Eye Height has been done. From the results, it has been concluded that DPSK modulation technique gives best performance with the Q-Factor of 20 and BER OF 1.5 and 10-91than the other techniques at the bit rates of 10 Gbps and 20 Gbps. DPSK shows 60% improvement in terms of Q-Factor respectively. AMI modulation technique can provide best Q- factor of 4.08 and improvement of 40 % at bit rate of 40 Gbps for a distance of 2500 km. Chirped Modulation achieves good performance at 10 and 20 Gbps. It is observed that IS-OWC systems using three different modulation techniques works well at 10 Gbps than 20 Gbps and 40 Gbps. The main challenge for this system is to eliminate noise, chromatic dispersion, selfphase and cross-phase modulation. So these modulation techniques improve the bandwidth, capacity and data rates of the proposed IS-OWC system.

DESIGN AND PERFORMANCE ANALYSIS OF XGM BASED FSO SYSTEM BY EMPLOYING HYBRID AMPLIFIERS AND SPATIAL DIVERSITY TECHNIQUE by Sukhjeet Kaur 

Abstract

Fso (Free Space Optical Communication) is that technique which is capable of working at bandwidth which is high and also having much acceptable data rates. Because nowadays internet is in trend, the capacity of speed of data should be very high. In other words, Free space optical (fso) communication is that type of communication technique which is effective in cost and having excessive bandwidth, whose demand has increased with recent commercialization utility. FSO communication technique is utilised in various telecommunication applications, underwater communication applications, intersatellite applications, indoor communication etc. Apart from these prevalencies, because of proliferation in free space, the signal gets deflated and information is lost till it arrives the receiver. These aspects affecting the exchange of information in FSO ought to have amplifiers to improve the information transmission from transmitter and receiver. Thus, in the optical field of communication, reclamation of signals electronically have become very costly process. Different power amplifiers have been employed which are capable of converting optical to electronic signals with much admissible costs. Here, various combinations of these amplifiers are analysed with spatial diversity technique in FSO. Amplifiers are used as hybrid amplifiers in order to overcome each amplifier’s obstruction. High peculiarity can be gained by using the technique of spatial diversity which is a process of posting several copies of same signal which is to be transmitted. Authenticity and availability of the FSO system is increased by concurrently transmitting same signal. Moreover BER degradation that's produced by way of atmospheric turbulence is diminished by using diversity. Highquality of the signal decreases due to environmental effect like fog, haze, rain and dirt in free space optical communication system. In spatial diversity, it is viable to lessen fading and in response greater traits of signal may be increased. The proposed system consists of 8 Tx/Rx as a spatial diversity technique along with hybrid amplifiers being placed on both transmitter as well as receiver side not only in series but also in parallel. Simulations are performed using Optisystem software and it has been observed that in proposed system EDFA-EDFA proves to be the best combination when employed either in parallel and series with less BER as compared to other two hybrid combinations for clear and haze weather. By using this parallel EDFA-EDFA combination Q-Factor is increased to 69.16 % as compared to SOA-EDFA and 11.43% when compared to RAMAN-EDFA in clear weather condition.Moreover while placing this combination in series Q-Factor is increased to 45.98% as compared to SOA-EDFA and 10.61% when compared to RAMANEDFA in haze weather condition. While analysing in Foggy weather in parallel configuration, RAMANEDFA performs better with its Q-Factor being increased to 50.3%comparing with SOA-EDFA and 4.5% as compared to EDFA-EDFA. Moreover power received is greater in parallel combination of amplifiers rather than placing them in series but errors are more in parallel than series configuration. EDFA-EDFA gives best results at 40 Km with much acceptable Quality Factor in clear weather, 6 Km in case of Haze weather and 3Km in Foggy weather in both series and parallel.

Abstract

Indian construction industry has major contribution towards development of country. In India  construction industry is expanding at good pace. With the development of country there will be construction of roads, bridges, flyovers, residential apartments, government sector and private sector infrastructure, airports, railways, ports etc. Construction depends highly upon heavy machinery. For production, mixing and pouring of concrete, various equipments are required and concrete pump is considered among highly critical equipments from execution and maintenance point of view. Therefore concrete pump needs better maintenance strategy to avoid breakdowns during pouring of concrete. At present the case company faces problems in prioritizing maintenance jobs, which results in higher maintenance cost, lower availability of machine, production loss and lower profitability. The present work is aimed to improve the maintenance strategies by using different MCDM techniques (modified TOPSIS, VIKOR and PROMETHEE) to find out most critical cause of failure for improving maintenance decision making concerning maintenance of Concrete Pump. For computing the weight of criterion Fuzzy SAW method is used, then using these weights maintenance criticality ranking is generated by using three multi criteria decision making (MCDM) techniques. Fuzzy SAW method determines the level of skill required as the most significant criterion followed by non-detection of failure, availability of spare parts, chance of failure, economic safety and no. of workers required. Best maintenance policy out of nine probable reasons of failure is identified using three MCDM methods, the most critical reason of failure according to modified TOPSIS, VIKOR and PROMETHEE rankings is material worn out (D7), second most critical reason of failure is quality of rubber (D6) and least critical cause is high pumping strokes (D1).

OPTIMIZATION OF SOME ENERGY CONSUMPTION AND WELD QUALITY RESPONSE PARAMETERS IN GAS TUNGSTEN ARC WELDING by Simranjit Singh 

Abstarct

Welding is most commonly adopted process for fabrication in the manufacturing industries and it is highly energy intensive in nature. During welding, there is considerable amount of energy losses which reduce the energy efficiency of the welding process. Most of the research has been focused on the parameters for weld quality but very less attention has been paid on energy consumption parameters related to welding. In the present research study, optimization of three energy consumption response parameters viz. power factor (PF), active power consumption (APC), active energy consumption (AEC) and three weld quality response parameters viz. tensile strength, bending strength, hardness has been carried out for gas tungsten arc welding (GTAW) of stainless steel 304. L9 orthogonal array of Taguchi method has been used for the design of experiments and analysis for the optimization by ANOVA at 95% confidence level. Three welding input parameters have been selected for the study which are welding current, gas flow rate and travel speed. Experimental conditions for optimum PF (0.58 Leading) have been found to be at 95 amps welding current, 5 lpm gas flow rate and 25 cm/min travel speed. Combination values for welding input parameters for optimum APC (1588.54W) are found to be welding current at 85 amps, gas flow rate at 10 lpm and travel speed at 21.17 cm/min. For optimum AEC (27.04Wh), values for welding input parameters are found to be welding current at 85 amps, gas flow rate at 10 lpm and travel speed at 25 cm/min. Optimum tensile strength (846.66MPa) has been found to be at welding input parameters of 95 amps welding current, 7 lpm gas flow rate and 13.84 cm/min travel speed. For optimum bending strength (57.75kgf), values for welding input parameters are found to be welding current at 90 amps, gas flow rate at 5 lpm and travel speed at 13.84 cm/min. Optimum value of hardness (277Hv) has been found to be at the welding input parameters of 85 amps welding current, 5 lpm gas flow rate and 25 cm/min travel speed. Taguchi analysis reveals that welding current is the most critical welding input parameter for PF, APC and hardness. Travel speed is found to be the most critical parameter for AEC, tensile strength and bending strength. Travel speed is found to be the significant factor for AEC. It has been found that there is 5.45% increase in PF from lowest value of PF which is a good improvement to tackle with the penalties in the electricity bills. There is 17.75% reduction in APC from highest value of APC by adopting values of welding input parameters for optimum APC. Validated experimental values of optimum APC and optimum bending strength are 5.70% and 2.18% higher than the predicted values respectively, but experimental value of optimum hardness is 0.63% lower than the predicted value. The effect of welding input parameters on tensile strength and

hardness are found to be similar as in the literature.

OPTIMIZATION OF SOME ENERGY CONSUMPTION AND WELD QUALITY RESPONSE PARAMETERS IN GAS METAL ARC WELDING by Taranvir S. Saini 

Abstract

In manufacturing industries, welding process is the most energy intensive due to large amount of energy losses associated with it and is commonly used for fabrication work. Very few researchers have explored the energy consumption parameters in case of welding processes, although these parameters are very important to make this process sustainable. The optimization of three energy consumption viz. power factor (PF), active power consumption (APC), and active energy consumption (AEC) and three weld quality response parameters (tensile strength, bending load and hardness) of Gas metal arc welding (GMAW) have been performed in the present research work. The welding voltage, travel speed and gas flow rate are selected as welding input parameters. The Taguchi based design of experiments has been generated by using L9 orthogonal array. Experiments have been conducted on SAE1020 mild steel work pieces and the most influencing parameters have been found using ANOVA. For optimum PF (0.73), the welding input parameters are found to be welding voltage of 30 volts, gas flow rate of 15 lpm and travel speed of 19.05cm/min. For optimum APC (2872.45W), the welding input parameters are found to be welding voltage of 30 volts, gas flow rate of 10 lpm and travel speed of 16.03cm/min. For optimum AEC (53.90Wh) and hardness (247.05Hv), the welding input parameters are found to be welding voltage of 30 volts, gas flow rate of 10 lpm and travel speed of 25.39cm/min and all three welding input parameters are significant for AEC. For optimum tensile strength (672MPa), the welding input parameters are found to be welding voltage of 35 volts, gas flow rate of 12 lpm and travel speed of 16.03 cm/min. For optimum bending load (984kgf), the welding input parameters are found to be welding voltage of 35 volts, gas flow rate of 10 lpm, travel speed of 16.03 cm/min and all three welding input parameters are significant. Welding voltage has been found to be most contributing welding input parameter for all response parameters. Validation result of optimum PF, AEC and bending load shows that experimental value of PF, AEC and bending load are lower than the predicted value of PF, AEC and bending load by 2.66%, 6.60% and 2.08% respectively, but validated optimum experimental value of hardness is 0.43 % higher than the predicted optimum value of hardness.

A ROBUST PASSIVE METHOD FOR DETECTION OF COPY-MOVE FORGERY IN IMAGES

by Geetika Gupta 

Abstrct

Today’s technological world is characterized by the presence of digital images that are vastly spreading all over the world and various image editing tools are available that have made very easy for a common user to create a digital forgery. Images are used as legal evidence in many fields and if these images are corrupted, then it will generate a crucial issue. A copy-move forgery is performed in images either for cloning, or concealing some object. In both situations, an image lost its integrity and hence detecting this type of forgery has becomes very challenging problem as the replicated zone arrives from the same source image. The primary objective is to develop a mechanism that will verify the credibility of an image and discover the duplicated areas in it. This research work proposes a passive procedure in which no information about the original image is involved. Firstly, the grayscale image is split into overlapping blocks and then hybrid (principal component analysis and histogram of oriented gradients) techniques are used for extracting the features. At last, the feature vectors are sorted lexicographically and replicated areas are matched. To compare the performance, an exact match method and proposed method was implemented. The proposed method reduces the false matches or discontinuities that have occurred in exact match method by using a preset offset threshold value. The qualitative inspection shows that the proposed method gives the best results and is more resilient under two different attacks (salt and pepper noise and filtering attack) as compared to exact match method. Moreover, the quantitative analysis shows that the proposed method gives the better results in terms of three different metrics, namely, precision, recall and accuracy. It achieves 86.96% precision, 80% recall and 84% accuracy as compared to exact match method.

STRENGTH AND CORROSION RESISTANCE OF CONCRETE USING COPPER SLAG AND SILICA FUME by Maninderjeet Singh 

Abstract

Presently world is seeing the advancement of extremely difficult and challenging structures, cement and fine aggregate as utmost essential which generally castoff basic substantial which own good quality. As in the conventional concrete cement which is a water based binder used to hold all other building material together, on the other hand fine aggregate used to occupy most of the volume present in concrete. Both the ingredients emits approximately equal amount of natural resources. In this manner to conquer the above harmful impacts, need to replace these materials with the newer one having same properties and should be economical. The inclusion of pozzolanic material with the OPC a century old practice is a substitute to these material in the construction monopoly. Additionally over the most recent couple of decades, there dated an increasing worldwide problem of deterioration of reinforced structures, brought about fundamentally by the degeneration of steel reinforcement embedded within the structure. There are a few factors which kept in mind to minimize the corrosion procedure in various type of inservice structures such as good concrete quality, surface conditions, and other indirect factors. The purpose of the research is to present the study on strength along with corrosion resistance of concrete employing copper slag (CS) and silica fume (SF). The objective of our study was to resolve the Compressive strength, split tensile strength and the corrosion resistance of concrete using Accelerated corrosion test with impressed voltage (ACTIV). The outcome displays that the adoption of CS and SF produces concrete with superior results than the conventional concrete at different substitution level of CS and SF with the fine aggregate as well as the cement. Furthermore the chloride convinced corrosion resistance of concrete measured with ACTIV technique is highly improved with combined use CS and SF respectively. Therefore the corrosion inhibition of concrete with both the pozzolans is higher than the normal concrete. From this we can concluded that the use of CS and SF is effective in exaggerate the chloride induced corrosion

of concrete.

IMPLEMENTATION AND PERFORMANCE ANALYSIS OF COGNITIVE RADIO WITH FREQUENCY UPDATING ALGORITHM ON SOFTWARE DEFINED RADIO PLATFORM by Jaskaran S. Phull 

Abstract

The field of wireless communication is ever growing and over the last 6 decades, the wireless standards have revolutionized the field of communication. Wireless communication is being used in all communication standards. For some of the advanced standards, the performance depends upon high gain. And for achieving high gain, the spectrum bandwidth is necessary. But day by day bandwidth scarcity is becoming a major concern for the upcoming wireless technologies. For this various techniques based on artificial intelligence has been designed. The basic intelligent radio called as cognitive radio has been designed which works on the basic principle of spectrum sensing and detecting the free frequency for transmission of secondary user which is basically unlicensed user. Conventionally, sincere efforts have been made to develop the algorithms or techniques for designing of the cognitive radio on MATLAB platform and also on other software’s intend for radio designing. In this work, an efficient technique has been developed to design cognitive radio based on SDR platform. On this platform, GNU Radio Companion has been used as the software part for signal processing and Universal Software Radio Peripheral is used for real time signal transmissions for designing of cognitive radio. The spectrum sensing energy threshold detection technique is used for this. In this work , a carrier frequency updating algorithm has been added to assess the performance of the proposed technique. This algorithm updates the frequency of secondary user in Linux terminal window. This makes the radio more reliable and efficient. Further the effect of noise on the secondary transmitter and spectrum sensor is also analysed using the SDR approach. The increased noise levels in the environment leads to frequency updating of secondary user even in absence of primary user. It is observed from the analysis that for every 10dB rise in Gaussian Noise, the bit error rate of secondary transmitter and spectrum sensor cause increment of 19.59% and 29.39% respectively. It is found that spectrum sensor is more easily prone to noise and the Gaussian noise causes the degradation of the system performance. It is further noted that the spectrum sensor should be programmed carefully to avoid the effect of Gaussian noise. From the above analysis, it is observed that best range of spectrum sensor under Gaussian noise is 0 to 0.1 dB to obtain minimum bit error rate. In future more work can be done using high range USRP as well as IP (Internet Protocol) based USRP which will make our radio more smarter and efficient. Even interfacing the GNU radio with MATLAB can prove better results without using the Python coding.

NUMERICAL ANALYSIS OF MULTILAYER REINFORCED POND ASH SLOPE

by Harleen Kaur 

Abstract

Coal ash is a waste product that is generated when coal is burnt in the thermal power plants. This coal ash is of further many types of which one is pond ash which is present as slurry in the ash ponds. According to the latest available data, 251.69 million tons of coal is used for generation of electricity which led to generation of 86.45 million tons of coal ash. Around 80% is fly ash (which is being utilized by civil engineers) and 20% is bottom ash. Now the task is to utilize this 20% to maintain the environment. In the present study, numerical analysis is carried out in which pond ash is been employed as a fill substance in the embankment slope. The bearing capacity is scrutinized by constructing a rigid footing (plain- strain) on the slope. The main rationale of this research is to scrutinize some prominent parameters which effect the behavior of a strip footing laid on a pond ash slope by the endosure of multiple layers of reinforcement (geo-grid and geojute), to have a better understanding about the fortification (reinforcement) system, and to suggest an appropriate geometry of reinforcement placement. The geo-grid reinforcement used is SGi 040 and geo-jute reinforcement used is DW TWILL. The physical properties of both the reinforcements were taken from the existing literature. To understand this ground improvement method, numerical investigation was conducted using a mercantile finite element software PLAXIS 2D version 8.0 to calculate the bearing capacity using geo-grid and geo-jute. The comparisons are made using two non dimensional parameters i.e. settlement ratio and bearing capacity ratio (BCR). The benefit of using these types of software’s is that they can be effortlessly used to examine geometric models which have not been examined in the laboratory yet. The number of multiple layers used are 1, 2, 3, 4 and embedment ratios used for modeling are 0.25, 0.5, 0.75 and 1.0 with De/B as 1, 2.3. The obtained results depicts that the load-bearing capacity is increased with increasing number of reinforced layers and De/B ratio. With increasing z/B ratio, bearing capacity is seen to decrease significantly. The ultimate bearing capacity comes out to be maximum when N=4. The percentage increase in the bearing capacity while using geo-grid as compared to geo-jute is about 18% approximately. The results of geo-grid and geo-jute are quite comparable, so the later can also be used depending on the requirement of load carrying capacity.

AUGMENTED REALITY FRAMEWORK FOR MAPPING AND ASSESSING COMPLETENESS OF OSM DATA by Kamalpreet Kaur

Abstract

Evolution with Web 2.0, GPS and developments in ubiquitous computing unveil the enormous potential in location based augmented reality applications. The mapping process for Open-StreetMap is carried out by web based editors like iD, JOSM or Potlatch and the contributors use these editors to make any contributions to this enormous VGI project. Mobility is not a part of this scenario as it should be in this era. Various studies have also shown ambiguities in the database occurring due to amateur contributors and have led to lower quality of data. There are so many unmapped areas in the world and more contributions to OSM will support growth of projects that make use of OSM data. Providing an augmented reality mobile tool can be very handy to increase both the contributor base as well as the feature completeness of OSM map data. This research work presents a mobile augmented reality tool in which contributors can capture data in real time and add it on OSM via the mobile application itself. The design of this framework has been kept minimal and easy for amateur users to follow through. The user has to hold the device when the values of azimuth and distance in the text overlays of camera preview stabilize. When editing, user has to select a marker from the fetched POIs. Out of three data elements, nodes, ways and relations, only nodes can be added and edited currently. A form to add and edit description of the captured node fetches tags from the Taginfo API, reducing the dilemma an amateur can confront while deciding which tags are suitable for the new node. OSM editing API has been used to upload new nodes and the edited ones as well. The contribution of the user can be seen under his profile at the OSM website. Analysis has also been done to ensure improvement in feature completeness of the study area. Overall this work satisfies the “on the ground rule” which states that mapping of the world should be done as it can be observed by someone physically there. Real time mapping experience has been accomplished in this work.

PERFORMANCE ANALYSIS OF CODED OFDM FOR DIFFERENT CHANNEL MODELS ON SDR PLATFORM  by Ashish Thakur

Abstract

With the tremendous growth in the demand for high-speed reliable wireless communication systems

worldwide, Orthogonal Frequency Division Multiplexing (OFDM) technique holds the promise for

achieving the spectral efficiency and high data capacity requirements for the upcoming wireless standards of the near future. It has other advantages such as its ability to reduce the inter symbol interference (ISI) and to handle the severe channel conditions. It is being widely used for recent wireless communication systems like 5G mobile communication, satellite communication and LTE systems. Coding of OFDM using Forward Error Correction (FEC) codes such as convolution coding helps in the transmission of source code in such a manner that the error probability minimizes over the crowded noisy channel by systematic addition of redundant bits. It reduces the bit error rate, hence improvement in reception. Convolution coding has ability for real time error correction. Along with it, Software Defined Radio platform being recently introduced has provided solutions to implement multiple standards on same platform without any alterations in hardware because it provides the entire signal processing functions at the software. It has provided with flexible, low cost and reliable solutions and also it has ability to incorporate artificial intelligence and to support future devices. Till now, FEC coding of OFDM has been implemented on SDR platform, but the impact of FEC on OFDM performance over both AWGN and fading (Rayleigh and Rician) channels in term of Bit Error Probability has not been studied. So the simulation of Coded OFDM on SDR and its performance under different channel models has been analyzed in this work. In this work via GRC simulations, it has been analyzed that the Coded OFDM has outperformed uncoded OFDM under all the considered channel models. The Coded OFDM with FFT length of 1024 with QAM 256 modulated data has outperformed uncoded OFDM by 6.57% and for Rician and Rayleigh channel, it has improved performance by 3.46% and 6.24% respectively. The systems based on Coded OFDM has better data rates, spectral efficiency and requires lower transmission power as compared to the Uncoded OFDM based systems under the considered channel models.
