Abstract:

This paper deals with Bayesian and non-Bayesian methods for estimating parameters of the bivariate Pareto (BP) distribution based on censored samples are considered with shape parameters λ and known scale parameter β. The maximum likelihood estimators MLE of the unknown parameters are derived. The Bayes estimators are obtained with respect to the squared error loss function and the prior distributions allow for prior dependence among the components of the parameter vector. .Posterior distributions for parameters of interest are derived and their properties are described. If the scale parameter is known, the Bayes estimators of the unknown parameters can be obtained in explicit forms under the assumptions of independent priors. An extensive computer simulation is used to compare the performance of the proposed estimators using MathCAD (14).

Abstract:

The present paper is on the analysis of surface roughness characteristics Ra, Rq and Rz during the machining of medium carbon steel EN19. The experiments have been done under dry environment by using a coated carbide tool. For the optimization of process parameters Taguchi based Grey Relational Grade method was used. Taguchi's standard L9 Orthogonal Array was used for conducting the experiments. From the Grey analysis, optimal parametric combination for multi-responses (Ra, Rq and Rz) was found at cutting speed: 225 mm/min, feed: 0.05 mm/rev and depth of cut: 0.4 mm respectively. Analysis of variance (ANOVA) was used for analyse the influence of process parameters on multi responses. From the analysis it is concluded that, speed has high influence (F= 34.18, P= 0.025<0.05) in getting the optimized values of multi responses and the depth of cut has very low influence (F= 1.34, P=0.427>0.05). Regression models were developed for Ra, Rq and Rz, which are very significant parameters from contact stiffness, fatigue strength and surface wear point of view. The models prepared were highly significant because they have high coefficient of correlation values (R2 =0.992, 0.987 and 0.982 for Ra, Rq and Rz respectively). Hence, the models can be used for accurate prediction of surface roughness characteristics.

Abstract:

Optimization of machining parameters is valuable to maintain the accuracy of the components and to minimize the cost of machining. Surface finish is an important measure for the quality of the machined parts. The present work is an experimental investigation to study the effect of machining parameters on Material Removal Rate and Surface Roughness in dry turning of medium carbon steel EN19. Taguchi's single objective optimization method was used to find the effect of input parameters on the responses. The experiments were conducted as per Taguchi's L9 Orthogonal Array on CNC lathe under dry conditions. Cutting parameters of speed, feed and depth of cut were taken as inputs and machining was done by PVD TiAlN tool. Regression models for the responses were prepared by using MINITAB-16 software. Analysis of variance (ANOVA) was used to find the influence of machining parameters on the responses. From the ANOVA results, it is clear that speed has high influence followed by feed and depth of cut has very low influence in achieving the optimum values for both Material Removal Rate and Surface Roughness. Finally, experimental and Regression values of responses were compared. From the results, it is found that both the values are close to each other hence, the regression models prepared were more accurate and adequate. Percentage of errors between experimental and regression values were calculated and they found in the range of ±0.20.

Abstract:

Non linear optical material has wide applications in the area of optical devices. That device mainly used to measure electromagnetic radiation. Single crystals of pure Bis thiourea Zinc chloride and Ferrous sulphate doped Bis thiourea Zinc chloride were grown by slow evaporation technique. The grown crystals have been subjected to powder X-ray diffraction to determine the crystalline size and unit cell parameter. The incorporation of ferrous sulphate in BTZC was confirmed by the EDAX and FTIR analysis. UV-Visible spectrum shows that the grown crystals have wide optical transparency in the entire visible region. The thermo gravimetric analysis suggests that incorporation of ferrous sulphate in the BTZC decreases the thermal stability of the grown crystal.

Abstract:

A growing body of data suggests that a significantly enhanced salivary cortisol response to waking may indicate an enduring tendency to abnormal cortisol regulation. More methods have been proposed to deal with forecasting problems using fuzzy time series. In this paper, our objective was to apply the response test to a population already known to have long-term hypothalamo–pituitary–adrenocortical (HPA) axis dysregulation. We hypothesized that the free cortisol response to waking, believed to be genetically influenced, would be elevated in a significant percent age of cases, regard less of the afternoon Dexamethasone Suppression Test (DST) value based on fuzzy time series and genetic algorithms. The proposed method adjusts the length of each interval in the universe of discourse for forecasting the Longitudinal Dexamethasone Suppression Test (DST) data on a fully remitted lithium responder for past 5 years who was asymptomatic and treated with lithium throughout the experimental results show that the proposed method gets good forecasting results.

Abstract:

This work is aimed at enriching a research theme, focused on exploiting the performance in a human-CNC machine interface (HCMI) environment. A salient contribution of this research effort is focused on adopting the concept of load cell for the system of human-performance measurement. The developed novel system is capable of measuring cognitive and motor action responses simultaneously. The performance measurement system designed for this work may be replicated for other fields where systems are operated through control panels and also where responses of mentally retarded human-beings (or the human beings with the symptoms of Alzheimer disease) are to be observed and evaluated. Research relevance: The research methodology designed in this work can be directly applied to the practical field to evaluate the performance in various human- panel operated system interface environments. This work suggests that those responsible for the function and operation of CNC-machines workstations would have to redesign the system to reduce injuries, as far as musculoskeletal and other related problems are concerned. The present work can be quite useful for the system designers of tomorrow.

Abstract:

A nine-switch power converter having two sets of out-put terminals was recently proposed in place of the traditional back-to-back power converter that uses 12 switches in total. The nine-switch converter has already been proven to have certain advantages, in addition to its component saving topological feature. Despite these advantages, the nine-switch converter has so far found limited applications due to its many perceived performance tradeoffs like requiring an oversized dc-link capacitor, limited amplitude sharing, and constrained phase shift between its two sets of output terminals. Instead of accepting these tradeoffs as limitations, a nineswitch power conditioner is proposed here that virtually "converts" most of these topological short comings into interesting performance advantages. Aiming further to reduce its switching losses, an appropriate discontinuous modulation scheme is proposed and studied here in detail to doubly ensure that maxi-mal reduction of commutations is achieved. With an appropriately designed control scheme then incorporated, the nine-switch converter is shown to favorably raise the overall power quality in experiment, hence justifying its role as a power conditioner at a reduced semiconductor cost.

Abstract:

In the recent decades, the construction of tunnels has been increased vastly in all over the world. Despite all the efforts have been put into the geotechnical investigation, determining the precise and reliable design parameters is a difficult task to accomplish. Therefore, using back analysis techniques to modify geotechnical parameters and optimize the design of initial and final supports is more effective and even less expensive nowadays. In this paper, the results of monitoring and instrumentation of Isfahan subway have been investigated. Moreover, two important parameters for stability analysis, the modulus of elasticity of rock mass and the coefficient of the lateral earth pressure, are modified based on the measured convergence by using the direct method. Results show the Young modulus of rock mass and the lateral earth coefficient are less than the initial values from geotechnical investigation.

Abstract:

One of the most difficult tasks of the patrol administrators is allocation of manpower; i.e. determining the. most effective level of operational manpower for patrol tasks. Typically, administrators resolve the allocation problem by relying on prior statistical data and by employing subjective analysis. In general, only limited systematic analyses have been applied to the problem. This thesis presents a non linear goal programming model for allocating patrolmen to road segments within a patrol region. The model is demonstrated via a case example of the East section of Visakhapatnam. The results of the model are valuable to the patrol administrator for considering departmental goals and priority structure, in addition to available historical data, in the assignment of patrol manpower for a given urban area.

Abstract:

Nowadays it is widely accepted that remote sensing is an efficient way of large data management philosophy. In this paper, we present a future view of the big data collection by synthetic aperture radiometry as a passive microwave remote sensing towards building a global monitoring system. Since the collected data may not have any value, it is mandatory to analyses these data in order to get valuable and beneficial information with respect to their base data. The collected data by synthetic aperture radiometry is one of the high resolution earth observation, these data will be an intensive problems, Meanwhile, Synthetic Aperture Radar able to work in several bands, X, C, S, L and P-band. The important role of synthetic aperture radiometry is how to collect data from areas with inadequate network infrastructures where the ground network facilities were destroyed. The future concern is to establish a new global data management system, which is supported by the groups of international teams working to develop technology based on international regulations. There is no doubt that the existing techniques are so limited to solve big data problems totally. There is a lot of work towards improving 2- D and 3-D SAR to get better resolution.

Abstract:

In this work, the effect of mixing ratio of cattle dung (CD) and poultry droppings (PD) on biogas generation was determined. Mixtures of various CD: PD ratios (100% : 0%; 50% : 50%; 60% : 40%; 80% : 20% and 0% : 100%) were prepared, analyzed and then aerobically digested for a period of 40 days. For each mixture, fermentation was carried out in a 20 L capacity digester. Results showed that biogas was obtained from the digestion of CD and PD alone, showing the biogas from CD was several times larger than that from PD. Furthermore, the resulted biogas yields from mixtures were found a function of the CD : PD ratio, the yield from the ratio 80 : 20 was the maximum. Biogas yields from the prepared mixtures were found and arranged from larger to lower in the form of (CD : PD) ratios as follow: 80% : 20%; 100% : 0.0%; 60% : 40%; 0.0% : 100%;50% : 50%. Addition of CD to PD enhances the PD production of biogas, while addition of a small portion of PD to CD gave the maximum yield, a result not determined in literature. In other hand, larger additions of PD to CD reduced the biogas yield. The effect of pH was also determined and found better around 7.0. These results are in agreement with research work in literature.
