Observing System Simulation Experiment

AbstractObserving system simulation experiments (OSSEs) are used to simulate and assess the impacts of new observing systems planned for the future or the impacts of adopting new techniques for exploiting data or for forecasting. This study focuses on the impacts of satellite data on global numerical weather prediction (NWP) systems. Since OSSEs are based on simulations of nature and observations, reliable results require that the OSSE system be validated. This validation involves cycles of assessment and calibration of the individual system components, as well as the complete system, with the end goal of reproducing the behavior of real-data observing system experiments (OSEs). This study investigates the accuracy of the calibration of an OSSE system—here, the Community Global OSSE Package (CGOP) system—before any explicit tuning has been performed by performing an intercomparison of the OSSE summary assessment metrics (SAMs) with those obtained from parallel real-data OSEs. The main conclusion reached in this study is that, based on the SAMs, the CGOP is able to reproduce aspects of the analysis and forecast performance of parallel OSEs despite the simplifications employed in the OSSEs. This conclusion holds even when the SAMs are stratified by various subsets (the tropics only, temperature only, etc.).

As a result of the analysis of statistics on the main failures of the turbocharger of tractor engines in agricultural production, it can be concluded that it is the condition of its bearing node, in the first place, determines the performance of the entire turbocharger. This ultimately affects the duration of the turbocharger rotor after the engine stops. The article considers the method of determining the rotation time of the turbocharger rotor by inertia depending on the following factors: the time of the pressure drop in the turbocharger grease system, the gap in the turbocharger bearing node, the frequency of rotation of the rotor before the engine stops. The results of experimental studies on the timing of the turbocharger rotor rotation after the engine stop for the regular mode of greasing the bearing node and when using an individual lubricant system are presented. Based on the experimental values obtained, it is concluded that the main indicator of the performance of the turbocharger is the duration of rotation of its rotor after the engine stops and the application of the individual system of lubrication of the bearing node of the turbocharger reduces the cost of bearing resource and increases the resource of the entire turbocharger of agricultural machinery engines at least twice.

Background: No data exist on the cutting efficiency of monopolar versus bipolar radiofrequency energy application systems on human meniscal tissue. Purpose: To compare the effects of monopolar and bipolar thermal energy systems on human meniscal tissue. Study Design: Controlled laboratory study. Methods: Fresh-frozen menisci were cut in cross-section into 180 pie-shaped specimens. A specially designed jig was used to consistently apply radiofrequency energy to the tissue under a constant 30-g force. Three different systems were tested at the low, middle, and high ranges, with application times of 1 and 3 seconds. Thermal effects were measured by image analysis microscopy. Results: No significant differences in thermal effects were found with respect to energy output for each system. Both the individual system tested and the application time had statistically significant effects on thermal damage, with the individual system tested having a greater effect. The mean depths of thermal change produced by the Mitek (bipolar) device were 564 and 648 μm at 1 and 3 seconds applications, respectively. The Arthrocare device (bipolar) produced depths of 1444 and 1697 μm at 1 and 3 seconds. The Oratec device (monopolar) produced depths of 895 and 1057 μm, respectively. Conclusions: A differential thermal effect was created in the meniscal tissue by three commercially available radiofrequency systems. Within the parameters of the experiment, all three systems limited thermal damage to a depth of less than 2 mm. The results appeared to depend more on the particular system used, not whether it had monopolar or bipolar electrodes. Clinical Relevance: These data imply reasonably safe (less than 2 mm) thermal changes in the meniscus after radiofrequency energy application from these three systems.

The Impact

The 1990s represent an exceptionally complex period for the population of Serbia. In addition to the impact of long-term factors, various tumultuous events affected its demographic development. How have these changes, or better to say dramatic events, affected an individual?s decision to have children? We tried to get an answer to the set question by analyzing cohort fertility rates. Examination of the average number of live births for women ages 35-39, 40-44, 45-49 and 50-54 in the year 2002 indicated that demographic cost was almost unregistered. However, as for the younger age cohorts of women, between 25 and 34 years old, the average number of live births in 2002 was lower than in 1991 for women of the same age group. The results of an in-depth non-representative research carried out during the nineties indicate that parenthood is the most important life aspiration and goal per se in the individual system of values, independent from age in our country. Therefore it seems that postponing births in conditions of long-term and great social crisis during the 1990-s, was an important reason of lower rates of cohort fertility of women born between 1977 and 1968. But certainly not the only reason. This is also seen in the low rates of cohort fertility of women of age 20-24 in the year 2002, in relation to the average number of live births of women of the same age group in 1991.

Held Back

About three years ago the system of individual instruction was introduced in the Winnetka schools by our superintendent, Dr. Carleton Washburne. This naturally had to be done gradually for after establishing definite goals for the work which must be accomplished in each grade, the material had to be prepared very carefully so that it would be as nearly self instructive as possible and the children could use it with a minimum amount of help from the teacher. Under this system a child progresses at his own rate of speed, neither being held back by slower pupils nor forced to go forward too rapidly for thorough understanding.

The article presents The unconventional use of PLC controllers in a distributed control system DCS were presented in this article. The functionality, requirements and the costs of installation and operation of commercial DCS systems and those built on the basis of PLC logic controllers were analyzed. The features, the architecture and the structure of DCS systems based on PLC controllers have been described in details. The particular attention was paid to the allocation of the individual system components to the appropriate layers contained in their structure.
