CRISIS OF EDUCATION: A SEARCH FOR SYSTEMATIC SOLUTION

Inner and outer expansions are used to formulate a systematic solution to the problem of the steady translation of a slender ship of arbitrary shape. Careful consideration is givien to finding the correct boundary conditions to be satisfied by successive terms in the expansions, and certain of the individual terms are determined partly or completely as functions of hull shape. Some results are given concerning the second approximations to the potential and wave resistance.

Recent WHO guidelines for antiretroviral therapy recommend switching to less toxic, but more expensive medicines for first-line and second-line ART, raising questions about the financial sustainability of many AIDS treatment programmes. At the same time, many key generic producing countries such as India now grant pharmaceutical product patents so competition between multiple manufacturers will not be able to play the role it has in bringing down the price of newer drugs. Overcoming these patent barriers will require a range of solutions, such as restricting patentability criteria, or compulsory licensing. One additional systematic solution is provided by the patent pool, a collective solution to the management of patent rights, initially presented by Médecins Sans Frontières to the French Foreign Ministry and subsequently the UNITAID Executive Board in 2006. A patent pool must not be implemented at any costs, but answer medical needs, be based on economic realities and meet the access needs of the developing world, including middle-income countries.

Long Term Preservation

The spread of COVID-19 has created numerous challenges in the field of archive management. Limited in-house office space, furloughs of personnel, and inconsistency, has highlighted the potential for the Carl Albert Congressional Research and Studies Center Archives (Center) to develop and implement improved accessibility measures to thousands of linear feet of material. Addition ally, the Center has found unique opportunities to collaborate with multiple academic institutions to propose large-scale digitization program exhibitions using the Center’s remote workflow model. One of the largest, most complex collections the Center has worked with during this time is the Political Commercial Collection (the Collection), which holds 119,000 film, audio, and videotape recordings of commercials aired between 1936 and present. It is the largest collection of political commercials in the world. The Center has developed a working pilot digitization project that has currently resulted in access to 16,000 digital videos for public researchers and over 10,000 available for on-line streaming during the pilot phase between April 16, 2020, and December 1, 2020. This paper presents the practical application of the Center’s simplified “Linear Reciprocity Workflow Model” to provide a systematic solution for digital and long-term preservation of complex collections. The Center has proven that limited personnel and reduced resources need not interrupt continued access to archival repositories.

Solution Classification

SUMMARYTensegrity mechanisms are composed of rigid and tensile parts that are in equilibrium. They are interesting alternative designs for some applications, such as modeling musculo-skeleton systems. Tensegrity mechanisms are more difficult to analyze than classical mechanisms as the static equilibrium conditions that must be satisfied generally result in complex equations. A class of planar one-degree-of-freedom tensegrity mechanisms with three linear springs is analyzed in detail for the sake of systematic solution classifications. The kinetostatic equations are derived and solved under several loading and geometric conditions. It is shown that these mechanisms exhibit up to six equilibrium configurations, of which one or two are stable, depending on the geometric and loading conditions. Discriminant varieties and cylindrical algebraic decomposition combined with Groebner base elimination are used to classify solutions as a function of the geometric, loading, and actuator input parameters.

Set Up

In December 2019, a contract between CNR and ECMWF was signed for a pilot ACTRIS/EARLINET data provision to the Copernicus Atmosphere Monitoring Service (CAMS). Such pilot contract (CAMS21b) aims to put in place a first data provision for a set of selected stations and it will demonstrate the feasibility of fully traceable and quality-controlled data provision for the whole network.In CAMS21b, the main effort is devoted to design, test and set up the provision of quality-controlled ACTRIS/EARLINET products in Real Real Time (RRT) and/or Near Real Time (NRT) to CAMS. The activities are focused on the automatic centralized data processing and data provision, ensuring the full traceability of the products from the data acquisition level up to the final quality-controlled data level. Most of the activities are done at ARES, the EARLINET/ACTRIS data center node at CNR, for assuring the centralized, harmonized and quality-controlled processing in compliance with FAIR principles.New modules and submodules of the ACTRIS/EARLINET Single Calculus Chain (SCC) as well as optimized algorithms for cloud screening have been designed. Additional procedures were implemented for improving the quality of the data provided in NRT, but also for the quality control of the Level 2 products which are delivered with a time delay.The release of a new version of SCC and of QC procedure is planned for mid-February.The data provision started in October 2020 at the test site of Potenza. A system has been set up for measurement reporting and monitoring of KPIs (Key Performance Indicators). After 3 months of measurements, the overall data provision system showed no critical points.In January 2021, the provision started for a group of 9 stations which are seen as representative for the whole network in terms of instrumental capability, but also ensuring a good geographical coverage of the European continent.In order to accommodate also measurements from non-continuous operation systems, a measurement schedule has been set up, compromising between the need of a large number of measurements and costs/efforts at each station. The measurement schedule has been designed through a representativeness study and foresees 6 slots of measurements per week, 3 in daytime and 3 in nighttime conditions.The successful implementation of the pilot allows the provision of aerosol optical property profiles to the CAMS services. from a set of observational sites distributed over the different European regions. These profiles is expected to be of interest for the assimilation, near real time evaluation and re-analysis evaluation of several CAMS products, including the aerosol load over Europe for air quality issues, atmospheric composition, climate forcing and solar and UV products. This allows for having a systematic solution for looking into specific events as they develop (e.g. the dust plume that you investigated earlier this month or the Californian fires in September), supporting or contradicting model forecasts. This pilot is the first provision of aerosol profiles from a high-quality ground-based network in NRT for this kind of applications. It is expected that these efforts will be continued in the next phase of CAMS/Copernicus (2021-2027).

At each specific stage of society development, certain guidelines dominate, which set the direction in solving the problems of educating the younger generation. We are deeply convinced that today such reference points are the creative and aesthetic factors that determine the basis of human spirituality. The essence of the proposed conception is education, an integral component of which is the systematic solution of various creative tasks in an aesthetically enriched environment. The pupils’ coordinated with age creative activity will contribute to increasing the motivation to work, developing the intellect, maximizing the abilities of each of them. Creative education, as it is understood here, involves the use of different methods, approaches to the child and its orientation towards achieving the most original result during the performance of any work, finding as many possible solutions for each new task as possible, comparing them to each other, choosing the best by the sum of specific indicators (profitability, environmental friendliness, aesthetics, etc.). In this context, creativity is also understood as ordinary work, the consequences of which are necessary for both the performer himself and other people. In some cases it is necessary to use special techniques of creative training KARUS.

Abstract As wind energy becomes a larger part of the world's energy portfolio, the control of wind turbines is still confronted with challenges including wind speed randomness and high system uncertainties. In this study, a novel pitch angle controller based on effective wind speed estimation (EWSE) and uncertainty and disturbance estimator (UDE) is proposed for wind turbine systems (WTS) operating in above-rated wind speed region. The controller task is to maintain the WTS's generator power and rotor speed at their prescribed references, without measuring the wind speed information and accurate system model. This attempt also aims to bring a systematic solution to deal with different system characteristics over wide working range, including extreme and dynamic environmental conditions. First, support vector machine (SVR) based EWSE model is developed to estimate the effective wind speed in an online manner. Second, by integrating an UDE and EWSE model into the controller, highly turbulent and unpredictable dynamics introduced by wind speed and internal uncertainties is compensated. Rigid theoretical analysis guarantees the stability of the overall system. Finally, the performance of the novel pitch control scheme is testified via the professional Garrad Hassan (GH) bladed simulation platform with various working scenarios. The results reveal that the proposed approach achieves better performance in contrast to traditional L1 adaptive and proportional-integral (PI) pitch angle controllers.
