Secret History

In 1948 an official ‘Transfer Committee’ was appointed by the Israeli Cabinet to plan the Palestinian refugees' resettlement in the Arab states. Apart from doing everything possible to reduce the Arab population in Israel, the Transfer Committee sought to amplify and consolidate the demographic transformation of Palestine by: preventing the Palestinian refugees from returning to their homes; the destruction of Arab villages; settlement of Jews in Arab villages and towns; and launching a propaganda campaign to discourage Arab return. One of the Transfer Committee's initiatives was to invite Dr Joseph Schechtman, a right-wing Zionist Revisionist leader and expert on ‘population transfer’, to join its efforts. In 1952 Schechtman published a propagandists work entitled The Arab Refugee Problem. Since then Schechtman would become the single most influential propagator of the Zionist myth of ‘voluntary’ exodus in 1948. This article examines the leading role played by Schechtman in promoting Israeli propaganda and politics of denial. Relying on newly-discovered Israeli archival documents, the article deals with little known and new aspects of the secret history of the post-1948 period.

The Family

Changing the system of family values, views of the society on the significance and functioning of the family institution contribute to the transformation of marital role relationships in modern families. The already formed model of role interaction, the ability of spouses to define and clearly distribute family roles and to treat them responsibly is the important factors in building constructive marital relations and creating a favorable psychological climate in the family. Objective. The research deals with the analysis of the essence of the “family role” concept and the classification of family roles; experimental definition and analysis of the main types of family roles in marital relations. Methods. Theoretical research methods were used to solve the research problem: analysis of scientific psychological literature, generalization method, systematization of scientific information. To solve the second part of the set objective, the empirical research methods were used, such as: conversation, psychodiagnostic method “Distribution of roles in the family” by Yu.Ye. Alioshyna, L.Ya. Hofman, O.M. Dubrovska, and also the method of processing and quantitative and qualitative interpretation of results. The research was conducted during September-October 2020. The study involved 11 married couples (husband and wife) with different marital experience of 22 people aged 25 to 47 years (Kyiv). All the couples have children aged 1 to 20 years. The results of an empirical study of the peculiarities of family roles distribution showed that the roles of entertainment organizer (63.64 %), master (mistress), (72.73 % and 63.64 %), the family subculture organizer (54, 55 % and 45.45 %) women and men share almost equally; the roles of educator and “psychotherapist” is more typical for women (90.91 % and 81.82 %); The role of sexual partner and the partner responsible for material support is more often performed by men (90.91 % and 72.73 %). The prospects for further research are seen in the study of role interaction in the parental families of adolescents and young people as a prerequisite for their future family roles.

Iron-related clogging of boreholes, pumps and dripper lines is a significant and costly problem for irrigators worldwide. The primary cause of iron-related clogging is still debated. Previous studies have described complex interactions between biological clogging and inorganic iron/manganese oxide precipitation. This case study examined groundwater bores used for viticulture irrigation in the Limestone Coast region, a highly productive wine growing area in the SE of South Australia. Iron clogging of bore screens, pumps and dripper systems has been a persistent problem in the region and the issue is perceived to be growing, with irrigators suggesting the widespread introduction of iron-related bacteria (IRB) through drilling equipment to be the root cause of the problem. Analysis of the groundwater microbiology and inorganic chemistry found no apparent correlation between the presence of IRB and the clogging status of wells. In fact, IRB proved to be widespread throughout the limestone aquifer. However, a clear correlation could be found between clogging affected bores and the redox potential of the groundwater with the most severely affected bores strongly oversaturated in respect to iron oxide minerals. Elevated dissolved concentrations of Fe(II) thereby tended to be found in deeper bores, which also were generally more recently drilled. Following decades of less than average rainfall, a tendency to deepen bores in response to widespread declines in water levels has been documented for the SE of South Australia. The gradually widening clogging problem in the region is postulated to be related to the changes in climate in the region, with irrigators increasingly driven to rely on deeper, anoxic iron-rich groundwater resources.

Modular design, Axiomatic design (AD) and Theory of inventive problem solving (TRIZ) have been increasingly popularized in concept design of modern mechanical product. Each method has their own advantages and drawbacks. The benefit of modular design is reducing the product design period, and AD has the capability of problem analysis, while TRIZ’s expertise is innovative idea generation. According to the complementarity of these three approaches, an innovative and systematic methodology is proposed to design big complex mechanical system. Firstly, the module partition is executed based on scenario decomposition. Then, the behavior attributes of modules are listed to find the design contradiction, including motion form, spatial constraints, and performance requirements. TRIZ tools are employed to deal with the contradictions between behavior attributes. The decomposition and mapping of functional requirements and design parameters are carried out to construct the structural hierarchy of each module. Then, modules are integrated considering the connections between each other. Finally, the operation steps in application scenario are designed in temporal and spatial dimensions. Design of cutter changing robot for shield tunneling machine is taken as an example to validate the feasibility and effectiveness of the proposed method.

Tunnel Testing

Localization and quantification of noise sources are important to fulfill customer and regulation requirements in a such competitive sector like automotive manufacturing. Wind tunnel testing and acoustic mapping techniques based on microphone arrays can provide accurate information on these aspects. However, it is not straightforward to get source positions and strengths in these testing conditions. In fact, the car is a 3D object that radiates noise from different parts simultaneously, involving different noise generation mechanisms such as tire noise and aerodynamic noise. Commonly, acoustic maps are produced on a 3D surface that envelopes the objects. However, this practice produces misleading and/or incomplete results, as acoustic sources can be generated outside the surface. When the hypothesis of sources on the model surface is removed, additional issues arise. In this paper, we propose exploiting an inverse method tailored to a volumetric approach. The aim of this paper is to investigate the issues to face when the method is applied to automotive wind tunnel testing. Two different kinds of problem must be considered: On the one hand, the results of inverse methods are strongly influenced by the problem definition, while, on the other hand, experimental conditions must be taken into account to get accurate results. These aspects have been studied making use of simulated experiments. Such a controlled simulation environment, by contrast to a purely experimental case, enables accurate assessment of both the localization and quantification performance of the proposed method. Finally, a set of scores is defined to evaluate the resulting maps with objective metrics.

AbstractThis article examines a subset of multilateral forums dealing with security problems posed by digital technologies, such as cyber warfare, cyber crime and lethal autonomous weapons systems (LAWS).1 It identifies structural issues that make it difficult for multilateral forums to discuss fast-moving digital issues and respond in time with the required norms and policy measures. Based on this problem analysis, and the recent experience of regulating cyber conflict and LAWS through Groups of Governmental Experts, the article proposes a schema for multilateral governance of digital technologies in armed conflict. The schema includes a heuristic for understanding human–machine interaction in order to operationalize accountability with international humanitarian law principles and international law applicable to armed conflict in the digital age. The article concludes with specific suggestions for advancing work in multilateral forums dealing with cyber weapons and lethal autonomy.

In practical engineering, due to the lack of information, it is impossible to accurately determine the distribution of all variables. Therefore, time-variant reliability problems with both random and interval variables may be encountered. However, this kind of problem usually involves a complex multilevel nested optimization problem, which leads to a substantial computational burden, and it is difficult to meet the requirements of complex engineering problem analysis. This study proposes a decoupling strategy to efficiently analyze the time-variant reliability based on the mixed uncertainty model. The interval variables are treated with independent random variables that are uniformly distributed in their respective intervals. Then the time-variant reliability-equivalent model, containing only random variables, is established, to avoid multi-layer nesting optimization. The stochastic process is first discretized to obtain several static limit state functions at different times. The time-variant reliability problem is changed into the conventional time-invariant system reliability problem. First order reliability analysis method (FORM) is used to analyze the reliability of each time. Thus, an efficient and robust convergence hybrid time-variant reliability calculation algorithm is proposed based on the equivalent model. Finally, numerical examples shows the effectiveness of the proposed method.
