Deformation Surface

The casing of deformable warheads warps under the action of deforming charges. The deformation profiles may be concave-, convex-, or D-shaped, but they are all symmetrical. The D-shape is considered the optimal deformation profile. The width of the deformed surface affects the number of fragments in the target area. In order to evaluate the deformable surface width of the cylindrical casing, a criterion α was established and its optimum range was determined as 20 to 30%. Based on our previous theoretical analysis, a MATLAB program that can rapidly evaluate the projectile deformation surface was compiled, which was verified using LS-DYNA and experiments. The laws influencing the deforming charge width on the deformed surface of the filled cylindrical casing were also studied using the MATLAB rapid evaluation program. As the deforming charge width increased, the deformation profile of the casing gradually transferred from “inner-concave” to the “outer-convex”. In addition, a formula that can better reflect the relationship between the deforming charge width φ and the criterion value α was fitted and verified. The conclusions obtained in this paper provide rapid guidance for the structural design of deformable warheads.

A development and evaluation the Cloud Computing (ClComp) of Ministry of Electricity and Energy of Egypt (MEEE) is presented in this paper. In order to be able to judge whether the ClComp of MEEE is competence, there is a need to develop criteria which performance can judged. Competency based standards and the ability to perform the activities within an occupation to the standard expected in the organization structure are presented. The key objective of Cloud Computing is to integrate Authorized Groups (AuthGs) development with the needs of the organization structures of MEEE. The ClComp of MEEE was developed jointly between the telecommunication information technology and ClComp services. Evaluation enables participant to distinguish between AuthGs centered view and a customer centered view of cloud computing of MEEE is competence evaluation. Recognize the main types of evaluation, explain the purpose of evaluation compare the approaches to cloud computing evaluation and review the relationship between the process and policy of evaluation are investigated. Microprocessor architecture presented an optimistic view of multicore scalability to develop the ClComp. Moreover this paper investigates the theoretical analysis of multiprocessor developing and scalability. The analysis was based on the laws of Amdahl's, Gustafson's, Hill's and Marty for fixed-workload condition. Moreover, challenged the difficulties to develop better cloud computing is taken into account. Also, multicore analysis of ClComp scalability, performance and power under fixed-time and memory-bound conditions are studied. These results complement existing studies and demonstrate that ClComp architectures are capable of extensive scalability and developing.

Point Of Departure

Taking a point of departure in the paradoxical fact that the increase in educational knowledge leads to an increase in uncertainty for educational organisations, this article explores how uncertainty and contingency have increasingly become an integral part of school governance. The article draws on Niklas Luhmann’s theory of ‘World Society’ as a functional differentiated society providing a range of different symbolic media for educational organisations. To trace the increase in the complexity of governing, we provide a historical account of the shifting couplings between schools and function systems. We show how the school becomes linked to an increasing number of symbolic media so that education becomes only one out of many other concerns. The article studies the consequences these shifting couplings have for how schools are governed and how they are expected to self-manage their relationship to different function systems. The article adds to existing studies of how education has become more and more differentiated with the argument that this has also led to new forms of couplings between schools and the education system with a number of important implications for the teaching profession.

The article is devoted to the study of such an important psychological phenomenon as an attitude of women to their own motherhood. It is summarizes the study of the problem of motherhood in psychological science in general. The article analyzes the problem of the influence of the relationship with the mother in childhood on the formation of a woman's attitude to her own motherhood in adult age. It is illuminates views of foreign and national researchers on the study of this phenomenon, as well as the essence of different areas of research on this phenomenon. Based on the theoretical analysis of the literature on this topic, the concept of "motherhood", its content and psychological essence is studied. Cultural-historical, biological, physiological and psychological aspects to the study of motherhood are singled out. The main content of scientific views on the formation of the phenomenon of motherhood is generalized. The main factors influencing the development of a woman's maternal sphere and the formation of the attitude to one's own motherhood are analyzed and considered. The content of such basic concepts as "mother's image" and "maternal relations" is revealed. The psychological features of the formation of an adequate image of the mother in the theoretical analysis of the ontogenesis of the maternal sphere are analyzed. The article also reveals the dynamics of motherhood in ontogenesis. The types of maternal relations and their role in the life of a mature woman are determined, as well as the influence of these relations on the formation of a woman's attitude to her own motherhood. The influence of different types of relationships between women and their own mothers on the level of formation of their attitude to personal motherhood has been empirically studied. Two groups of women were studied, one group had a positive relationship with their own mother, and the other had a negative one. In the course of the research the differences between different types of maternal relations and the level of formation of a woman's personal attitude to motherhood are singled out.

The introduction outlines the motivation for investigating the relationship between autonomy and rationality in contemporary bioethics, and maps the contours of a pre-theoretical understanding of autonomy, in preparation for the theoretical analysis to come. Having noted some apparent ambiguities and tensions within the widely accepted assumption that there is a close relationship between autonomy and rationality, the author briefly distinguishes procedural and substantive accounts of autonomy, and identifies Beauchamp and Childress’ pioneering work in the principles of biomedical ethics as providing the standard account of autonomy in bioethics. He outlines some objections to the standard account, and goes on to outline a framework that is used in the rest of the book for developing a rationalist account of autonomy that aims to avoid these objections.

This paper proposes the theoretical model to analyze the performance degradation of control systems subject to common-source digital upsets. In this paper, a multidimensional hidden Markov model (MDHMM) is used to characterize the correlated upsets and reveals the relationship between complex environments and stochastic random digital upsets injected into the control systems. These digital upsets coming from artificial complex environments are operated on distributed redundant processing controllers. Furthermore, this paper develops the theoretical analysis model for performance degradation of control systems under common-source digital interferences modeled by MDHMM. Theoretical estimations for different redundant configurations are analyzed. Then corresponding simulation verifications for a specific control system are also conducted in details and compared with the theoretical analysis results. These analyses can help to select an optimal redundant design and provide an example for control systems design. This analysis also helps to balance the performance of system, reliability of system, and costs of system design in applications.

The Relationship

This study examines the relationship between inclusiveness with respect to the structural design of the participatory process and resource allocation outcomes in participatory budgeting. Empirically, this article examines the case of participatory budgeting in Seoul, South Korea, where redistribution is not an explicit goal. Findings suggest that creating organizational structures that enable and encourage public participation has led Seoul’s participatory budgeting to distribute public funds toward poor neighborhoods. Points for practitioners Participatory budgeting is an exemplar practice of public participation in the government decision-making process. It is a local budgeting practice that allows the public to participate, discuss, deliberate, and decide where and how to spend public money. This study highlights the importance of designing inclusive organizational structures in participatory budgeting to encourage public participation. Empirical results underscore the link between inclusive organizational structures and more equitable allocation outcomes.
