structural steel sections are mainly used in beams and columns of building frames. iran national steel industrialgroup is among the oldest and largest producers of beams in iran. it has two beam production lines, namely line630 and line 650. in this study, the mechanical properties of manufactured beams in these production lines werecompared. based on the t-test results, the elongation is signi...

As an automatic method of determining model complexity using the training data alone, Bayesian linear regression provides us a principled way to select hyperparameters. But one often needs approximation inference if distribution assumption is beyond Gaussian distribution. In this paper, we propose a Bayesian linear regression model with Student-t assumptions (BLRS), which can be inferred exactl...

The aim of this paper is to empirically investigate the in sample and out of sample forecasting performance of several GARCH-type models such as GARCH, EGARCH and APARCH model with Gaussian, student-t, Generalized error distribution (GED), student-t with fixed DOF 10 and GED with fixed parameter 1.5 distributional assumption in case of Colombo Stock Exchange (CSE), Sri Lanka.

T-algebra is an interactive learning environment for step-by-step solving of algebra problems in four areas of mathematics, including linear equations. To make the diagnosis of mistakes more complete and the program more intelligent we designed our own rule dialogue. Each solution step in T-algebra consists of three stages: selection of the transformation rule, marking the parts of expression, ...

The value of experiential learning in agricultural education has long been recognized as an important part of the educational process. Through practice and experience students apply what they have learned in real situations, thus the material becomes understandable and usable. Moreover, in the process of gaining experience, new problems and situations arise causing learners to seek additional i...

Background—The Iowa Department of Education undertook a study to determine district characteristics that are associated with success on statewide-standardized tests. A district profile was created for each Iowa public school district to determine if any association exists between a particular district’s characteristics and the test scores of 11th grade students. Contextual variables such as soc...

BACKGROUND The number of medical undergraduates taking part in Student Scientific Activities (SSA) at Jessenius Faculty of Medicine Comenius University in Slovakia remains low. The aim of this study was to discover some of the factors responsible and suggest improvements. METHODS An anonymous 30-item questionnaire was devised and sent to 245 medical undergraduates (UG) of the 1st, 2nd, 3rd an...

Although the rise in subprime lending and the ensuing wave of foreclosures was partly a result of market forces that have been well-identified in the literature, in the United States it was also a highly racialized process. We argue that residential segregation created a unique niche of poor minority clients who were differentially marketed risky subprime loans that were in great demand for use...
