Problem statement: Currently, there is a need in the space industry to actively improve the characteristics of battery batteries, the use of new types of batteries for power supply systems of spacecraft leads to a constant demand to improve the control and verification equipment (CPA). Depending on the improvement of storage batteries (AB) for spacecraft, the requirements for electrical inspections and control and verificationequipment were gradually changed. With the advent of lithium-ion batteries for spacecraft, there was a need to develop and manufacture a charge-discharge hardware and software complex (ZRPAK). The charge-discharge hardware-software complex designed to work as a charger-bit complex to work with AB spacecraft for all ground operation phases, to verify compliance of the electrical characteristics of the AB to the specified requirements, conduct incoming inspection and Autonomous tests of AB on the manufacturer of the spacecraft. The advantages and disadvantages of the previously developed and currently used control and verification equipment are analyzed. The electrical characteristics of the KPA of all generations of development are summarized in the table. Based on the analysis of the development of batteries, trends in the development of control and verification equipment and the fact that all spacecraft of new developments will use only lithium-ion batteries, the requirements for a promising fifth-generation ZRPAK are formulated. The following requirements are applied to the fifth-generation charge-discharge software and hardware complex: increase the charge-discharge voltage to 150 V; increase the charge -discharge current to 150 A; introduce devices for pre-charge-pre-discharge of the battery into the KPA; increase the accuracy of measuring the voltage of each battery; provide remote operation from the control PC; writing cyclograms; logging and subsequent viewing of all test data

This article analyses, defines, and refines the concepts of ownership and personal data to explore their compatibility in the context of EU law. It critically examines the traditional dividing line between personal and non-personal data and argues for a strict conceptual separation of personal data from personal information. The article also considers whether, and to what extent, the concept of ownership can be applied to personal data in the context of the Internet of Things (IoT). This consideration is framed around two main approaches shaping all ownership theories: a bottom-up and top-down approach. Via these dual lenses, the article reviews existing debates relating to four elements supporting introduction of ownership of personal data, namely the elements of control, protection, valuation, and allocation of personal data. It then explores the explanatory advantages and disadvantages of the two approaches in relation to each of these elements as well as to ownership of personal data in IoT at large. Lastly, the article outlines a revised approach to ownership of personal data in IoT that may serve as a blueprint for future work in this area and inform regulatory and policy debates.

Infrared and visible image fusion technologies make full use of different image features obtained by different sensors, retain complementary information of the source images during the fusion process, and use redundant information to improve the credibility of the fusion image. In recent years, many researchers have used deep learning methods (DL) to explore the field of image fusion and found that applying DL has improved the time-consuming efficiency of the model and the fusion effect. However, DL includes many branches, and there is currently no detailed investigation of deep learning methods in image fusion. In this work, this survey reports on the development of image fusion algorithms based on deep learning in recent years. Specifically, this paper first conducts a detailed investigation on the fusion method of infrared and visible images based on deep learning, compares the existing fusion algorithms qualitatively and quantitatively with the existing fusion quality indicators, and discusses various fusions. The main contribution, advantages, and disadvantages of the algorithm. Finally, the research status of infrared and visible image fusion is summarized, and future work has prospected. This research can help us realize many image fusion methods in recent years and lay the foundation for future research work.

This paper presents a new complete CAD-driven rapid prototyping system for polystyrene. ModelAngelo, as it is called, consists of six subsystems featuring hardware and software. The system utilizes a virtual 3D CAD model to produce a set of commands used to control a 5-axis CNC Machine to move a heated-wire tool into a block of polystyrene to form the desired surface. The ultimate goal of ModelAngelo is to reach the stage of “what you see is what you get”. An overview of ModelAngelo system is first presented followed by a detailed discussion of ModelAngeloSoftware. The various mechanical subsystems responsible for realizing the final product are then described. Advantages and disadvantages of several tooltip designs are discussed and the best solution is selected. The main features of the robotic arm, which carry the tooltip is also discussed in detail. Finally ModelAngelo controller that manages the interaction between software and hardware is briefly highlighted and possible applications of ModelAngelo are suggested.

1. Earlier work on the digestibility of Calluna vulgaris has been briefly reviewed.2. Determination of the digestibility of heather has been made by two methods, viz. (a) the conventional procedure involving the use of metabolism crates and (b) the lignin-ratio technique applied to tethered sheep.3. A diet consisting of heather alone, and fed in metabolism crates, proved unsatisfactory as a result of low feed intake. Agreement between duplicate sheep in respect of digestive capacity was also poor.4. Satisfactory feed intakes were attained when heather was admixed at levels of 40 and 70% with hay. At both levels the digestibility of the organic matter was approximately the same, and agreement between sheep was good except for crude protein.5. The lignin-ratio technique applied to tethered sheep gave digestibility coefficients for organic matter which were consistent with those obtained by the conventional method; the values for crude protein were somewhat higher. While the organic matter of 10-year-old heather was digested to about the same extent as that of 4-year-old heather, its crude protein digestibility was rather less.6. The advantages and disadvantages of both methods have been discussed; it has been concluded that the lignin-ratio technique is likely to play a useful part in future work of this kind.7. These preliminary results suggest that heather has a higher nutritive value than earlier work would indicate, and that even the winter foliage may compare favourably with hay of moderate to poor quality.

Salt Caverns

ABSTRACTThe geomechanical and mining-technological aspects of the construction of salt caverns as disposal chambers have been investigated during project phase 2, completed by mid 1981. With a view towards the stability analysis of such a cavern, FEM-estimates have been carried out and evaluated. From these it can be derived that- a rotational ellipsoid would be the most suitable shape- its dimensions should be 82 m (vertical axis) and 42 m (horizontal axis)- the distance (safety pillar) between the neighbouring caverns should be 170 m (vertical) and 180 m (horizontal).For practical engineering purposes the rotational ellipsoid can be modified into a cylinder with conic bottom and top. The numerical model simulated the short term as well as the long term characteristics of the surrounding salt rocks. The short term characteristics were assessed by an elastic approach, the long term characteristics by a rheological model. The input parameters have been determined by means of laboratory tests on ASSE rock salt.In a second step the characteristics of partially and completely filled caverns were simulated. It was shown clearly that deformation of the salt rock comes to a halt when counteracted by the filling.Based upon the results of the stability analysis, investigations were made to find out a suitable mining technique for the construction of the cavern. Solution mining and conventional development by means of drilling and blasting have been studied alternatively. Since both methods have their advantages and disadvantages a decision in favour of the one or the other cannot be made until the actual site has been defined.
