Novel High Accuracy Resolver Topology for Space Applications

In recent years, the space industry has experienced a significant change mainly due to the incursion of private companies, which has shaken up the sector. This new situation allows for a reduction regarding the reliability of conventional instrumentation for space while reducing the development time and manufacturing volume. Consequently, even though it has been typical to use equipment that was previously tested in space, this could be the right moment to introduce new technologies due to the previously mentioned reasons. One of the interesting technologies with great potential is the rotary sensor in applications with motors. Historically, the resistive potentiometer has been the most used due to its simplicity and robustness; however, it has several drawbacks. Due to this, the aim of this paper is to identify an interesting rotary sensor. Hence, in this article, different sensor types are studied. Then, we review the literature regarding resolvers in order to find the best topology. We designed and compared different single speed absolute position resolvers to find the ones that offered the best results. In this process, a novel resolver topology was designed that improved on the performances of any other studied topology.

The Right

This chapter focuses on how technologies used in the management of migration—such as automated decision-making in immigration and refugee applications and artificial intelligence (AI) lie detectors—impinge on human rights with little international regulation, arguing that this lack of regulation is deliberate, as states single out the migrant population as a viable testing ground for new technologies. Making migrants more trackable and intelligible justifies the use of more technology and data collection under the guide of national security, or even under tropes of humanitarianism and development. Technology is not inherently democratic, and human rights impacts are particularly important to consider in humanitarian and forced migration contexts. An international human rights law framework is particularly useful for codifying and recognizing potential harms, because technology and its development are inherently global and transnational. Ultimately, more oversight and issue specific accountability mechanisms are needed to safeguard fundamental rights of migrants, such as freedom from discrimination, privacy rights, and procedural justice safeguards, such as the right to a fair decision maker and the rights of appeal.

Soft Manipulator

The rising interest in soft robotics, combined to the increasing applications in the space industry, leads to the development of novel lightweight and deployable robotic systems, that could be easily contained in a relatively small package to be deployed when required. The main challenges for soft robotic systems are the low force exertion and the control complexity. In this manuscript, a soft manipulator concept, having inflatable links, is introduced to face these issues. A prototype of the inflatable link is manufactured and statically characterized using a pseudo-rigid body model on varying inflation pressure. Moreover, the full robot model and algorithms for the load and pose estimation are presented. Finally, a control strategy, using inverse kinematics and an elastostatic approach, is developed. Experimental results provide input data for the control algorithm, and its validity domain is discussed on the basis of a simulation model. This preliminary analysis puts the basis of future advancements in building the robot prototype and developing dynamic models and robust control.

The Right

Faced with protecting the right to privacy and, with it, the inviolability of homes, the development of new technologies and the possibility of developing work from home has opened the door to a series of new conflicts that require us to provide a specific legal framework by which such situations can be addressed. In the Spanish case, we speak of Law 10/2021 from 9 July on remote working. The objective of this study is to assess the scope as well as the problems that this law generates during its application, regarding controlling the provision of services. However, we not only identify the incidental factors, but also provide a necessary reinterpretation of the right to privacy from the perspective of the inviolability of homes, especially when its current articulation may operate to the detriment of employees’ rights, as contradictory as this may seem.

Industry 4.0 revolution, with its cutting-edge technologies, is an enabler for businesses, particularly in reducing the cost and improving the productivity. However, a large number of organizations are still too in their infancy to leverage the true potential of Industry 4.0 and its technologies. This paper takes a quantitative approach to reveal key insights from the companies that have implemented Industry 4.0 technologies. For this purpose, 238 technology companies in Malaysia were studied through a survey questionnaire. As technology companies are usually the first in line to adopt new technologies, they can be studied better as leaders in adopting the latest technologies. The findings of this descriptive study surfaced an array of insights in terms of Industry 4.0 readiness, Industry 4.0 technologies, leadership, strategy, and innovation. This research paper contributes by providing 10 key empirical insights on Industry 4.0 that can be utilized by managers to pace up their efforts towards digital transformation, and can help the policymakers in drafting the right policy to drive the digital revolution.

Damage Tolerant

Two principal approaches are available to materials’ engineers to improve the overall cost-weight balance of metallic airframe structures: improving alloy performance and optimising materials’ utilisation. Although both approaches have been successful in the past, they are most effective when applied concomitantly. The Aluminium industry has a long record of improving aerospace alloys’ performance. Nevertheless, even in apparently well-explored alloy systems such as the 7xxx family, products with improved damage tolerance-strength balances have recently been developed, thanks to an improved understanding of the optimum Zn-Mg-Cu combinations for the required property balances but also to developments in casting capability. Novel dispersoids and dispersoid combinations have enabled further improvements of the performance of existing alloy families. For example, appropriate Sc and Zr additions have a significant impact on the grain structure of 2xxx alloys and thus on performance. Another high potential approach for alloy performance improvements is the optimisation of Al-Cu-Li-(Mg-Ag-Zn) alloys. These so-called “third generation Al-Li alloys” were principally developed for military and space applications; in order to meet the demands of future commercial airframes, more damage tolerant variants are being developed. AA2198 and AA2050 are used to illustrate the potential of these higher damage tolerance Al-Cu-Li alloys. However, materials performance improvements are only part of the potential developments of metallic solutions for airframes. Further gains of a similar magnitude in component weight and cost can be achieved by applying new technologies and new design solutions to metallic structures. The future of metallic airframes will depend on the concomitant application of both these approaches.

As we know, one of the lifelong learning forms, which is the correspondence education, has received a wide circulation in our country. However, we have recently mentioned that the type of education should be adapted to modern conditions. As a way out from this situation, the article analyzed the specifics of the distance and supplementary education in the world and the stages of development. Mechanisms of application of existing educational technologies in Azerbaijan were studied. In order to achieve the goals mentioned in the article, the relevant legislation of Azerbaijan has been prepared and recommendations for institutional reforms have been prepared. In the context of globalization, the development of new technologies has negative effects, though there are positive effects. The strengthening of globalization leads to the inequality of development among countries, the sharp differences in the living standards of the population, the escalation of language, religion, traditions and, ultimately, the weakening of national state institutions. In this case, the protection and development of the state language is of great importance and special attention should be paid to this problem. At the end of the article, we came to the problem from another aspect, and we believe that if we use the right technologies properly and precisely, it can be achieved through the promotion of mother tongue. Our compatriots living abroad will be able to acquire new knowledge and will not forget and develop their mother tongue with effective use of remote training technologies. Millions of our compatriots living abroad will be able to benefit from these advantages. In order to achieve this, it is important to use the modern IT technologies' innovations as well as the effective use of language teaching methods for language development carried out by linguists. We believe that there is a relationship between these two factors, and when analyzing lifelong learning issues, there is a need for two aspects. At the end, it should be noted that we have to analyze the problem from different perspectives and make suggestions.

In all EU Member States the status of people employed on job platforms is not fully legally regulated. It is necessary to consider the sources of the contemporary phenomenon of electronic employment, which is not amenable to legal regulation in the Union constituting an “area of freedom, security and justice with respect for fundamental rights” (Art. 67 (1) of the Treaty on the Functioning of the European Union). The right to work in decent conditions, with adequate remuneration, belongs to this category of rights. In the discussion on employment platforms state authorities are more inclined to consider issues related to new technologies, processes and changes caused by the development and application of modern digital technologies (digitization) in almost all areas. The headquarters of trade unions mainly discuss the legal position of employees and the role of employment platforms in employment relations in the post-industrial era. Entrepreneurs and their organizations, including private institutions and employment platforms, are interested in equal treatment by national legislators in local labour markets. They are afraid of the breach of the balance favorable to their own economic interests, caused by the public interest in the possibility of using employment in atypical forms of employment. Services consisting in employment provided under employment platforms are incomparably cheaper than identical work performed by employees employed under employment contracts.
