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).
Key word: bivariate Pareto distribution, censored samples, importance sampling, maximum likelihood

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]

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.

- Control Method for Unified Power Quality Conditioner Using
Fuzzy Based Nine-Switch Power Conditioner
K.Gowthami, P.Nagendra, M.Subrahmanyam, M.Shobbha
[Abstract]
[PDF]
[Cite]
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.

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-

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.

Abstract:
This paper focuses on the works of designing a small scale wind turbine at arbitrary conditions
and analyzing the structural integrity of the model via numerical simulation. The project interests are limited to
geometric design of turbine blade, optimizationandaerodynamicaswellasstructuralanalysis.Design of Horizontal
Axis Wind Turbine (HAWT) blade particularly for low wind speed areas is of primary concern to this project.
The generation of wind turbine profile is based on Blade Element Momentum theory (BEM). Design parameters
like angle of attack, tip speed ratio, aerodynamic coefficients, angle of twist, airfoil profile, chord length are
addressed with the aid of this theory. A three dimensional blade is then obtained by extruding the two
dimensional airfoil profiles to operate at a rated speed of 5m/s.
Numerical simulations are carried out using a commercial CFD solver ANSYS CFX which reveals the flow
structure and aerodynamic characteristics. The results obtained from the combined use of open source software
QBlade and CFD computation assure that the 2.5 m long blade made of Polyester resin could withstand extreme
loading conditions and provided acceptable performance with regard to stress and deflection produced..
