A. Kavitha, B. Kiruhtika
Abstract - The quadratic Diophantine equation given by 5x2-2y2=27 is studied for determining its infinitely many non-zero integral solutions. A few interesting properties among its solutions are given. Also, knowing an integral solution of the given hyperbola, integer solutions for other choices of hyperbolas and parabolas are presented. Also, employing the solutions of the given equation, special Pythagorean triangle is constructed.
2 Implementation of FIR Filter using Wallace Multiplier based on Symmetric Stacking
P. Pooja, T. Kavitha
Abstract - A new binary counter design is proposed which groups all of the “1” bits together using symmetric bit stacking. The bit stacks are then converted to binary counters, producing 6:3 and 7:3 counter circuits eliminating exor gates on the critical path. This avoidance of exor gates results in reduction of delay and power consumption. By using these symmetric stacking based counters a Wallace multiplier is designed with the help of Xilinx 14.7 version. FIR filter is implemented by using bit stacking based Wallace multiplier which reduces the delay and power consumption of FIR filter up to 61 percent and 4.16 percent respectively when compared to normal FIR.
3 Implementation of Lean Six Sigma in a Small Scale Mushroom Production Plant: At Basic Level
Kamal Kishor, Baldev Singh Rana, Dr. Sunil Thakur
Abstract - Lean Six Sigma is one of the most important and popular development in the field of quality. Lean Six Sigma is the combination of two different methodologies “Lean” focuses on elimination of wastes and “Six Sigma ’’ reduced the rate of defects. This research focuses on Mushroom production plant wastes. There are several wastes in Mushroom plant such as Compost waste, Poly propylene bags (compost bags), mushroom waste and water waste. In order to improve the production process in mushroom plant lean six sigma method is conducted. DMAIC (Define, Measure, Analyse, Improve, and Control) is used as a methodology, Ishikawa diagrams are also used to analyse the data. After implementation of lean six sigma there is reduction in wastes from 8-12% and increases the overall efficiency.
4 Improved Diagonal Loading for Robust Adaptive Beamforming Based On LS-CMA
Michael Joseph Shundi, Grace Gregory Mihuba
Abstract - Least Square-Constant modulus algorithms (LSCMA) is a popular method for blind adaptive beamforming. LSCMA is efficient and having good performance when used in communication channels having constant modulus properties like FM, MSK, QPSK, PSK or BPSK. However, LS-CMA can also be used successfully with signals which are non-constant modulus if the Kurtosis of the beam former output is less than two. This is greatly significant because it vindicate that the LS-CMA is also robust to symbol timing error when used to pulse shaped PSK signals. Despite its effectiveness, good performance and its wide applications, LS-CMA comes along with several sensitive problems that have never really been solved. In particular LSCMA has a tendency of steering the maximum radiation power in the direction of interfering signal even if the interfering signals are not modulated, thus causing interference. In this paper, a general knowledge of blind adaptive beamforming is briefly reviewed to create a good awareness to the readers of this paper and a new concept in diagonal loading is formulated to solve the sited problem. The new concept formulated in this paper involves reconstruction of covariance matrix of the input data where spatial matched filter is used; and its output added diagonally to identity matrix. The simulation results which was done by comparing the developed algorithm with the convectional RLSCMA, conventional LS-CMA and modified LS-CMA in [1] significantly confirmed that the proposed algorithm solved the problem and highly improved the performance of adaptive beamforming based on LS-CMA.
5 Effect of Partial Replacement of Fine Aggregate by Marble Powder on the Fresh and Hardened Properties of SCC
Vyshak Sajeev, Thariq I, Muhammed Hussain N, Nibin N, Muhammed Razi K, Abi Basheer
Abstract - Self-compacting concretes (SCC) are highly fluid concretes that can flow and be placed in formwork under their own weight without the requirement of internal or external energy. This fluidity is obtained with the use of high paste volume and super plasticizer. The paste of SCC is made principally of cement, which is the most expensive component of concrete. As a result, the production cost of SCC is higher than conventional concrete. However, to make the manufacture of SCC more practical and economical, the binder is often a binary, ternary even quaternary compound: Portland cement mixed with mineral additions. The primary aim of this work is to study the effect of incorporating marble powder as a partial replacement to Fine aggregate. Assessment of Hardened properties was limited to Compressive and flexural strength. Two types of curing (ponding and polythene curing) were adopted for the study. The mix design adopted was M30.Out of the various % replacements, the optimum % replacement of marble powder was found to be 20% and performed well in both fresh and hardened properties. Optimum compressive strength with water curing at 28 days is 38 N/mm2and for polythene curing is 29 N/mm2The obtained results revealed the possibility of replacing fine aggregate with 20% marble powder and also polythene curing can be adopted in water scarce areas.
6 Fracture and Fatigue Evaluation of Injection Moulded 316L Stainless Steel Powder Using Wax–Based Binder
Mohd Afian Omar, Norazlan Roslani, Noorsyakirah Abdullah, Nurazilah Mohd Zainon
Abstract - Metal Injection Moulding (MIM) is an advanced near net shape forming process for high quality of complex shapes combined with high properties of materials. For economic reasons, it is necessary to have demand for a large quantity of parts. This paper presents the attempt to investigate the fatigue behavior of injection moulded MIM specimen using wax- based binder system. The stainless steel powder with the median particle size of 16 mm and a binder consisting of major fraction of paraffin wax and a minor fraction of polyethylene were mixed at 160°C using a sigma-blade mixer for one hour to prepare the feedstock. The injection moulded specimen was injection moulded using 80 ton metal injection moulding machine with the nozzle temperature of 200C. Prior to sintering at 1360C, the specimens were debound using a combination of solvent extraction and thermal pyrolysis method. The specimens were then sintered under vacuum. The fatigue properties of the specimen were analyzed and discussed. Furthermore, the microstructure study of the sintered specimen also been carried out to look for the mechanism of the failure.
7 A Novel Traffic Congestion Minimization Technique for VANET using Opportunistic Routing and BFO
Aditi Saini, Er. Pritpal Singh
Abstract - Traffic congestion has emerged as an issue of global interest and both governments and academia are developing innovative solutions to mitigate this issue. This paper proposes a novel congestion minimization technique named MARC-ORBFO which focuses on refining an existing congestion minimization approach that performs routing using an optimal relaying distance function and incurs high packet drops. The proposed congestion minimization algorithm exploits social relationships among the nodes to make next hop selection using dynamic optimization with BFO in order that packet delivery probability is maximized and high packet delivery rates be achieved. The main focus of this research is to show the effectiveness of opportunistic routing and BFO in reducing congestion and achieve better results in comparison to [9]. The proposed technique is simulated using ONE simulator and its performance is evaluated in terms of parameters such as general level of congestion, packet drops, average travel time and total CO2 emissions. Simulations reveal that the proposed algorithm achieves 20% improvement in Congestion Estimation, 25% reduction in Average Travel Time, 7% reduction in CO2 emissions and 12% reduction in packet drops when compared to [9] and hence outperforms [9] in terms of all the considered parameters.
8 Design of Fast and Area Efficient Fault Tolerant Parallel FFTs using Partial Summation ECC
T. Deepika, SmithaShree Mohapatra
Abstract - The increasing demand of low complexity and error tolerant design in signal processing systems is a reliability issue at ground level. The complexity of communications and signal processing circuits increases every year which is done by the CMOS technology scaling. This increased complexity makes the circuits more vulnerable to errors. As soft errors pose reliability threat to modern electronic circuits, it becomes necessary to protect circuits against soft errors. The ABFT techniques are well suited for communications and signal processing applications as they use algorithmic properties to detect and correct errors. One example is FFT. In this brief, ECC technique is first applied to protect parallel FFTs, then Parity-SOS and Parity-SOS-ECC techniques are applied. Then, an improved protection scheme that combine the use of error correction codes and Parseval sum is proposed and evaluated. The results show that the proposed scheme can reduce the implementation cost of protection.
