This study has been made to augment the engine operating factors for the most beneficial enactment of a diesel engine driven with amalgams of honge methyl ester by the application of taguchi method. Investigations had been carried on a liquid cooled single cylinder CI engine. Which is loaded by eddy current dynamometer. The investigation done beneath various operating situations of engine such as operating capacity, timing of injection, air fuel ratio, and compression ratio. Brake Thermal Efficiency and nitrogen oxides (NOx) emissions were studied for different operating conditions. Mathematical reckonings were established to foretell the BTE and NOx. An ANOVA analysis used to be studied the most sizable parameters affecting the responses. It was found that the injection timing and engine load were major effect in the BTE however the Engine load, compression ratio and injection timing strongly have an effect on NOx emissions. With use of MINITAB optimization has been performed. The optimization results were shows that load of 81.3%, the usage of 16% combination percentage, 16 compression ratio, injection timing of 26.36° BTDC have been found to be peak quality and the resultant of BTE and NOx were 36.5% and 240 ppm, correspondingly.

The Utilization of natural fibers for various polymeric applications in increasing owing to its cost effectiveness and versatile applications. In this work four different Tri layer hybrid composites were developed by using hand lay up by varying the kenaf and ramie fibers in different stacking sequences. Fourdifferent hybrid composites with K1-Kenaf/Ramie/Kenaf (KE/RA/KE) K2-Ramie/Kenaf/Ramie (RA/KE/RA) K3-Kenaf-Kenaf-Kenaf (KE/KE/KE), K-4 Ramie-Ramie-Ramie(RA/RA/RA) were investigated. Tensile, Flexural, Impact and Shore-d Hardness were investigated. Outcome of the results depicted that the tensile, flexural and hardness studies possessed similar results. The Composites with ramie fiber at skin layer and kenaf as core material posseseed good tensile, flexural and hardness properties, Similarly the kenaf at outer layer and ramie as a core had better impact strength. The outcome reveals that the composites can be used as an alternative in structural and automobile ***(Scanning ElectronicMicrscopy) was done to observe fracture surfaces, Fiber pull out and void formation.

Missing requirements or incomplete requirements about the project is making delay in projects and that affect customer satisfaction. This problem is caused due to customer or requirement engineer. If it is due to customer then customer may not give it during requirement elicitation. If it is due to requirement engineer then requirement engineer may not collect it during elicitation. Or it is caused the inefficiency of both the parties. To avoid the missing requirements problem, this paper is expressing an intelligent approach.

Mathematical modelling for the design of DFT processor using resource sharing

引用

AIP Conference Proceedings 2020年第1期2277卷

作者： S. Narendran J. Selvakumar 1Research Scholar Department of Electronics & Communication Engineering SRM Institute of Science and Technology Chennai India 2Associate Professor Department of Electronics & Communication Engineering SRM Institute of Science and Technology Chennai India

In this paper, we have presented a modelling of Discrete Fourier transform (DFT) using resource sharing technique. In our design, we bit sliced the architecture and reduce the computation cost. Since twiddle factor plays a vital role in discrete Fourier transform. This bit slicing technique will reduce hardware cost and improvise speed of the processor. We made a mathematical derivation for N - point Radix - 25Fast Fourier Transform using bit slicing approach by reducing the twiddle factor value. By slicing the 64 - point FFT, we have designed a Superconducting based DFT processor. At which, we reduced the number of multipliers and adders in the design using radix - 25 method. Fast Fourier Transform are used in the applications like spectrum analyzer, signal detector, and a major part in Orthogonal Frequency Division Multiplexing (OFDM) devices. With our modeling approach, we can compute any n2 - point Fast Fourier Transform (FFT).

This research paper presents a unique biodiesel, Bael biodiesel, with diesel vehicles. Bael oil is produced from bael seeds, which are obtained from the fruits of the bael tree. Within that article, the performance, toxicity, and ignition properties of a diesel engine running on diesel, bael seed oil methyl ester (BSOME) and its blends (B20, B40, B60, B80, and B100) are discussed. Due to the increased acid quality of the oil, BSOME was constructed by mixing bael seed oil and methanol in an acid as well as alkali catalytic process. While BSOME as well as its blends have poorer brake thermal efficiency than diesel, they have smaller emissions, with the exception of NOx. According to this research, blend B20 (20% bael biodiesel + 80% diesel) can be used to partly replace diesel in conventional CI engines despite imposing some modifications.

Application of delay differential equation in queueing theory

AIP Conference Proceedings 2020年第1期2282卷

Queuing Theory is the mathematical theory of waiting lines, queues or traffic. The term “customer” generally implies for a person, but also refer to a lot of other examples. A car in the lane waiting at a toll plaza, a program running in queue in a processor, or an airplane waiting to take-off after the air traffic becomes normal. In the above-mentioned cases there are several queues where the customer often has a number of choices of queues to choose ***, in this particular study we are introducing about the symbolic structure of the differential equation of queuing theory & discuss on a model of n-lines where the data of the length of a line given to the consumer is not current, but rather a delayed one, i.e. the given data gives information about the system at a previous time. So here the equations controlling the system become what we call the delay differential equations. In particular, we are going to imply that this delay causes the oscillations in length of the queues because of n-bifurcations.

Dielectric properties of high percentage Mg doped CaCu3Ti4O12, CaCu3-xMgxTi4O12 (x=0.20 and 0.50) ceramics carried out. They were synthesized by the semi-wet route using a solution based citrate-nitrate method along with inexpensive solid TiO2 powder. X-ray diffraction analysis reveals that the ceramics form single phase when sintered at 950 °C for 12h. SEM analyses show the smooth surfaces of grains with a spherical appearance. The grains of CCMTO2 and CCMTO5 ceramics were found to be in the size range of 1-5 μm and 1-3 μm, respectively. Dielectric studies show that the CCMTO2 ceramic has higher value of dielectric constant and lower dielectric loss in comparison to that of CCMTO5. © 2019 SPIE.

This investigation presents a numerical exploration of magnetohydrodynamic (MHD) natural convection within a differentially heated square cavity containing Cu-water nanofluid (NF) that has a Prandtl number of 6.2, considering variable thermophysical properties. The impacts of Rayleigh number between 10 3 and 10 7 , nanoparticle volume fraction between 0 and 9 %, and Hartmann number Ha between 0 and 100, on flow behavior and heat transport (HT) characteristics are examined. Results indicate that increasing the Rayleigh number enhances fluid motion and HT, while the inclusion of Cu nanoparticles further augments HT due to improved thermal conductivity. However, high concentrations of nanoparticles can reduce the efficiency of convective HT. The presence of a horizontal magnetic field, represented by the Hartmann number, was found to decelerate fluid motion due to the Lorentz force, diminishing the effectiveness of convection and shifting the dominant HT mode towards conduction.
