The need of descriptive geometry (DG) course reorganization in the direction of reflecting in it the foundations of modern computer 3D geometric simulation techniques is shown. The full rate use of 3D methods calls on students a special theoretical training. New techniques require the knowledge of computer as modern 3D geometric simulation tool. A new theoretical course composed of three modules has been proposed. The basics of 3D are given initially. Then, in accordance with the FSES-3 requirements, the DG elements are given by the example of positional tasks, but they are also underpinned by 3D-methods. The proposed DG course reorganization on the basis of 3D computer geometric simulation will permit to equip the students with new methods of decisions related to graphic tasks, significantly increase their competitiveness on the labor market, as well as to raise the graphics chairs’ rating.

Abstract This paper presents the innovative approaches that can be implemented in teaching descriptive geometry by using a Computer-Aided-Design-Drafting (CADD) software. Examples of line relations, line/surface relations, and plane/cylindrical solid intersections are given in the paper. The paper first discusses the principles of descriptive geometry, and then focuses on how these principles can be applied in a CADD environment. In addition, new methods that take advantage of CADD are also provided. The paper emphasizes creativity while solving descriptive problems by using a CADD software. Although all examples illustrated in CADKEY, the concepts revealed in this paper can be applied to other 3-D CADD software, such as AutoCAD 10 and will significantly improve the engineering student’s CADD skills.

Descriptive geometry is one of the disciplines that for a long time is the basis for training engineers of various specializations. However, with the advent of modern computer 3D technologies, the place and role in engineering of many traditional disciplines requires rethinking. The article is devoted to the integration of methods of descriptive geometry into the educational process of preparing students of higher educational institutions.

AbstractObservations of the giant irregular galaxy NGC 4449 are being used to study the correlations between the diameter or luminosity and the velocity dispersion of its giant HII regions (GHRs), understanding as GHRs those HII regions with supersonic velocity dispersions. In the central part of this galaxy the HII regions overlap, and also there is a strong, morphologically diffuse emission that permeates the main body of NGC 4449, both effects making difficult the detection, identification and separation of HII regions. We have developed new techniques to solve these problems, obtaining HII regions parameters equivalent to the ones that would be got if the HII regions did not overlap and if the diffuse emission did not exist.

Conjunctive Analysis

Steps for conducting Conjunctive Analysis of Case Configurations (CACC) are well documented in the literature; however, methods for identifying and quantifying “situational clustering” vary and are often based on subjective interpretation of a CACC truth table. In response, the current article presents two new techniques that (a) enable researchers to determine whether data used to populate a truth table cluster significantly within dominant case configurations and (b) apply an established metric from the economics literature and modified for configural analysis to quantify its relative magnitude. These new methods are applied to four existing CACC studies, demonstrating how they offer a more systematic, transparent, and replicable approach to analyzing and interpreting case configurations than what is currently used.

It is generally recognised that the Working Group on the Rotation of the Earth that was set up after IAU Symposium No. 82 has successfully achieved its principal objectives, namely: “to make recommendations on … future international services on earth-rotation” and “to obtain and analyse data on earth-rotation by both current and new methods …”. In particular, by organising Project MERIT, it has stimulated the development and use of new techniques and it has brought together in fruitful collaboration scientists from many countries and disciplines. Other subsidiary objectives have also been achieved and the project has been extended through cooperation with the COTES Working Group on the terrestrial reference system. The possible reasons for this success are also reviewed in the expectation that the conclusions will be relevant to other future projects.

Primary Contribution

The primary contribution of this work is to develop direct processes of explicit Runge-Kutta type (RKT) as solutions for any fourth-order ordinary differential equation (ODEs) of the structure u ( 4 ) = f ( x , u , u ′ , u ′ ′ ) and denoted as RKTF method. We presented the associated B-series and quad-colored tree theory with the aim of deriving the prerequisites of the said order. Depending on the order conditions, the method with algebraic order four with a three-stage and order five with a four-stage denoted as RKTF4 and RKTF5 are discussed, respectively. Numerical outcomes are offered to interpret the accuracy and efficacy of the new techniques via comparisons with various currently available RK techniques after converting the problems into a system of first-order ODE systems. Application of the new methods in real-life problems in ship dynamics is discussed.

The Brain

The present paper argues that the development of a new methodology in studying the brain has resulted in a change of our views on the way it works, has seen the emergence of new ideas, and a considerable modification of traditionally accepted theories. The most significant are neuroplasticity, negative activity network (NAT), the nature of aphasic disorders, and the approach to the localization of brain functions. New brain imaging techniques have confirmed also the ability to change the neuronal circuits by mental force. Moreover, new techniques have brought about a rise in new methods for both the diagnosis and rehabilitation of individuals with various brain disorders. Most valuable in this respect has proved to be neurofeedback. We have concentrated on the most important contributions of Prof. Pąchalska in the implementation and development of these new ideas on brain functioning. We also emphasize the fact that her theoretical considerations are firmly based upon her extensive (forty years) work with brain damaged patients.

Social work is unusual among the professions for its commitment to advocacy on behalf of the poor, the dispossessed and the disadvantaged. International human rights and the promotion of social and economic justice are clearly a part of this mission. The article addresses an emerging aspect of advocacy by examining the nexus between international social and economic justice issues and the social work response. It addresses the revolution in advocacy methods created by information technology. These new techniques can offer a wealth of opportunities to further develop the international advocacy component of the social work profession. The impacts these new methods can have on the creation of justice on a global level are discussed.

In this study, two new techniques are proposed for accelerating the multi-point optimization of an airfoil shape by genetic algorithms. In such multi-point evolutionary optimization, the objective function has to be evaluated several times more than a single-point optimization. Thus, excessive computational time is crucial in these problems particularly, when computational fluid dynamics is used for fitness function evaluation. Two new techniques of preadaptive range operator and adaptive mutation rate are proposed. An unstructured grid Navier–Stokes flow solver with a two-equation [Formula: see text] turbulence model is used to evaluate the objective function. The new methods are applied for optimum design of a transonic airfoil at two speed conditions. The results show that using the new methods can increase the aerodynamic efficiency of optimum airfoil at each operating condition with about 30% less computational time in comparison with the conventional genetic algorithm approach.

Four methods for improving maintenance training are described: (1) team training, (2) follow-on training at operational sites, (3) programmed instruction, and (4) a specific example of a “directed troubleshooting” technique. Maintenance training can be improved by new techniques of organization, new methods of teaching, and by developing new working skills.
