Further calibration

Velocity model technique is routinely used to convert data from the time-to-depth domain to support prospect evaluation, reservoir modelling, well engineering, and further drilling operation. In Vietnam, the conventional velocity model building workflow oversimplifies the interval velocities as only well interval velocities are populated into 2D grids for depth conversion or oversimplified calibration interval velocities by applying a single scaling factor function.

In solving the problem, this study developed a calibration procedure of HEC-HMS model with four steps for reducing parameter’s uncertainty and improving model performance, which include (1) identifying the number of sub-basin, (2) determining the optimal combination of loss model and transform model, (3) finding out the sensitive model parameters, and (4) further calibrating model.

This study aimed to Performance of seven radiation models. The objective was to determine the most accurate model for estimating solar radiation. Performance and Evaluation of all the models on the same basis is prerequisite for selecting an alternative approach in accordance with available data such as air temperature (Tmax, Tmin, Tmean), actual sunshine hours (n), Relative Humidity (Rhmax, Rhmin & RHmean) and potential sunshine hours (N).

This article examines the nature of English as a foreign language (EFL) learners’ appraisal confidence and appraisal calibration in EFL reading comprehension. Appraisal confidence refers to the degree to which test takers identify the probability that their test answer is correct or appropriate in percentage terms (e.g., 0%, 25%, 50%, 75%, or 100%). Appraisal calibration refers to the accuracy of test takers’ appraisal confidence by comparing their appraisal confidence to their test performance in percentage terms. Two hundred and three students studying Master of Education (M.

Syngenta Seeds’ Gary Wietgrefe points out several of the impediments to widespread adoption of HTF corn (Ed Zdrojewski in BioFuels Journal, 2003b). To begin with, starch and ethanol yield vary by geographic region and from year to year, making an optimizing hybrid choice difficult. Further, choosing a hybrid that maximizes ethanol qualities may mean a tradeoff with yield and other potentially valuable qualities, such as protein content and even test weight (because of moisture). Testing equipment pres- ents its own challenges.

Describing the very active Swiss programme, G. Müller outlined in detail the key contributions. They include the World Calibration Centre for Ozone, Carbon Monoxide and Methane, the QA/SAC Switzerland, and the World Optical Depth Research and Calibration Centre. Mr Müller, the Rapporteur on Strategic Planning and Implementation of GAW, has led the effort to produce the GAW Strategic Plan (GAW Report No. 142). He pointed out that Swiss scientists have been active in assisting with the establishment of the Nairobi ozonesonde measurements and the Mount Kenya Global station.

Our study constitutes a basis for further analyses of the equilibrium level of credit in the economy and investigations of ¯nancial stability. In order to prove this, we note that the econometric analysis in this article have been replicated and extended by Serwa (2011) to build a model identifying both normal and boom regimes in the credit market. In turn, Rubaszek (2011) have calibrated a version of the model including housing to data on the banking sector in Poland. His results suggest that incorporating housing in the model signi¯cantly increases the volume of credit in the economy. ...

The aim of this paper is to compare pricing and performance of mutual funds with two types of guarantees: a lookback guarantee and an interest rate guarantee. In a simulation analysis of different portfolios based on stock, bond, real estate and money market indexes, we first calibrate guarantee costs to be the same for both investment guarantee funds. Second, their performance is contrasted, measured with the Sharpe ratio, omega and Sortino ratio, and a test with respect to first-, second- and third-order stochastic dominance is provided.
