Given the growing level of competition in telecom, it has become very difficult to raise prices of service offers in time. In order to make a well informed decision, several parameters must be taken into account. Some of these parameters are market driven, for instance a demand-curve showing the amount...
A generalized correlation in terms of the reduced molar refraction parameter r is proposed for the calculation of the viscosity of dense hydrocarbon fluids. The input parameters are the refractive index and density at 20 °C, molecular weight, critical temperature, and pressure. For saturated gases (Pr < 1), the absolute...
The aim of this research is to enable corrections to color values of woven fabrics by changing the constructional parameters. It was assumed that when a yarn of certain fineness was not available, it was substituted with a yarn of lower fineness. The different thread fineness caused color deviations between...
The parameters tested in this study that relate to the stability are the stability/gel time at and below 90°F (32°C). The installers want the longest stability possible so they have a safety factor in how much time they have to get the material in the pipe. They also want a...
The Dirichlet process prior allows flexible nonparametric mixture modeling. The number of mixture components is not specified in advance and can grow as new data come in. However, the behavior of the model is sensitive to the choice of the parameters, including an infinite-dimensional distributional parameter G0. Most previous applications...
This paper proposes a probabilistic approach for estimating parameters of an option-pricing model from a set of observed option prices. The approach is based on a stochastic optimization algorithm, which generates a random sample from the set of global minima of the in-sample pricing error and allows for the existence...
Dodecyl benzenesulfonic acid DBSA surfactant was used in the present study to find the effect of concentration on its electrical conductance in solution from 293-323 K above and below the critical micelle concentration CMC. The micellization parameters i.e. degree of counter ion binding ( ß), aggregation number n and number...
This paper shows how to use the Kalman Filter (Kalman, 1960) to back out the shocks of a dynamic stochastic general equilibrium model. The idea is as follows: First, to write the model in what is called the State-Space Representation. Second, using the Kalman Filter to write the likelihood function...
This paper proposes model that is based on the simplified description of the thread structure and it works with the textile description of thread structure. The formation of the liquid in the longitudinal textile is described in detail, and particular phenomena are discussed. Important parameters are used in the model...
"Since credit risk valuation attempts to quantify firms default risk, we propose to apply one alternative approach of fault tree, or equivalently, reliability study to assess firms’ default risk. We set a very simple framework and use French firms’ bankruptcy statistics to quantify default probabilities. From these empirical default...
This paper explains an Euler equation for per capita consumption to investigate whether social security increases consumption ceteris paribus in seventeen countries. Following the seminal work of Martin Feldstein, the literature has estimated consumption functions to address this question. Unfortunately, consumption functions confound structural and expectational parameters, making their interpretation...
This paper focuses on the practice parameters, which summarize the scientific research evidence about conduct disorder in children and youth in order to provide information about effective practices for assessment, treatment, and prevention. The target audiences for these parameters include families, policymakers, and frontline workers, such as social workers, psychologists,...
This white paper research is exploring intelligent drilling that can be applied to multiple applications. The paper reveals that the methodology uses a neural network to classify material lithology where the inputs to the neural network are sensed drill parameters such as thrust, torque, rotary speed and penetration rate, as...
Achieving financial improvements requires proper analysis of many requirements and parameters. Changing one input design parameter often results in modifications to other parameters. For example, changing the HRSG design changes efficiency, fuel cost, capital cost, debt financing, and emission rates. Often it is important to assess the impact of a...
The article examines how different binomial stochastic processes alter the pricing of credit derivatives, and define which credit risk parameters are of critical interest. By examining the behavior of state prices obtained from a binomial credit risk model, we are able to suggest which credit risk parameters are of critical...
This paper deals with the advanced night vision device, the Panoramic Night Vision Goggle PNVG that presents the wearer with a large horizontal field of view (100 degrees) by combining the output from multiple image intensifier tubes. This significantly complicates the testing and evaluation of this state-of-the-art device. This paper...
Queries and reports provide the means by which we ask questions and get answers from a database. In this paper, learn how to use parameters to add flexibility to your queries and reports, and how to supply parameters through a custom-designed form. The paper provides a downloadable database with examples...
When you want to restrict the data that you work with, based on the value contained in a field, you can use criteria in your query. When you want a query to prompt you for a value or pattern every time you run it, you can create a parameter query....
When you use Web queries in Microsoft Excel, you can import refreshable data into your worksheets. You can also edit a Web query to prompt for variable parameters; for example, a Web query that gets stock quotes from a Web page can prompt for a parameter like a stock symbol...
A parameter query enables you to prompt for information, such as criteria for retrieving records in a form or report that is based on the query. You can also pass parameters from one data access page to another by using cookies. This paper explains the various steps to pass parameters...
