in this paper, simulation and analysis of thin steel cylindrical shells with elliptical cutouts under oblique loading were studied using finite element method. first, the numerical results were validated by the results of experimental test performed by an instron 8802 servo hydraulic machine. also, the effect of cutout angle (θ), cutout size, cutout position (l0/l) and cutout aspect ratios (b/a...

the aim of this research was to investigate performance of two combined plows compared to conventional plow. the experiments were conducted in a loamy soil texture with moisture content of 16-18% in karaj region of iran. combination of moldboard+chisel plow and disk plow+chisel plow were compared with conventional moldboard plow as three treatments. data was statistically analyzed using rcbd in...

Usability testing, commonly conducted for commercial software to ensure that it meets the needs of the end user, is likewise vital to creating effective training software employing VR technologies. However, developers often limit software testing to expert evaluation (by other developers or subject matter experts [SMEs]) to identify potential problems that might impede the usability or acceptab...

For many years we have heard rumors of the downfall and death of GSS research. In this paper we will argue that the nay-sayers are wrong, as many have been in other disciplines in the past and that they would propose to stop seeking answers before the most important questions may have even been asked. We describe some of the many unanswered research questions left to be addressed in Group Suppo...

The Sloan Digital Sky Survey (SDSS) is the largest ongoing sky survey. It regularly makes data releases to the astronomical community. From a macroscopic point of view, a profound question is: what is the role of SDSS data releases in the evolution of the relevant scientific fields? In this paper, we introduce an integrated approach by combining statistical, information-theoretical, and symboli...

This paper generalizes the discussion about disagreement versus uncertainty in macroeconomic survey data by emphasizing the importance of the (unknown) true predictive density. Using a forecast combination approach, we ask whether crosssections of survey point forecasts help to approximate the true predictive density. We find that although these cross-sections perform poorly individually, their...

Objectives: This study explored how social physique anxiety (SPA) combined with different patterns of motivation regulations might facilitate versus deter effort and enjoyment in physical education (PE) and leisure-time physical activity. Design: Cross-sectional survey. Methods: High school students (N 1⁄4 298; Mage 1⁄4 15.72, SDage 1⁄4 1.24 years) completed an in-class survey including SPA in ...

In Ireland, men who have sex with men (MSM) have increased HIV risk. Pre-exposure prophylaxis (PrEP), combined with safe sex practices, can reduce HIV acquisition. We estimated MSM numbers likely to present for PrEP by applying French PrEP criteria to Irish MSM behavioural survey data. We adjusted for survey bias, calculated proportions accessing testing services and those likely to take PrEP. ...

In 1997 the author conducted a survey at the IEEE workshop on ‘Automatic Speech Recognition and Understanding’ (ASRU) in which attendees were offered a set of twelve putative future events to which they were asked to assign a date. Six years later at ASRU’2003, the author repeated the survey with the addition of eight additional items. This paper presents the combined results from both surveys.

INTRODUCTION This study describes the uses of a control chart in the malaria surveillance at the local level, signaling whether there is a need to intensify or adapt control measures. METHODS The districts of Cruzeiro do Sul (n=14), State of Acre, Brazil, were classified into three groups: I) those with an incidence lower than expected; II) those with an incidence within the expected range; a...
