Zn-Ti co-substituted LiZn microwave ferrites: Sintering characteristics and gyromagnetic properties

To meet the low-loss and high-frequency application requirements of modern electronic information systems for integrated microwave devices, Zn-Ti co-substituted LiZn microwave ferrites were prepared in this work. The results demonstrated that Zn-Ti co-substitution promoted the grain growth and densification process during sintering, leading to a decrease in the pore-induced linewidth (ΔHp) of LiZn composite microwave ferrites; the introduction of non-magnetic Zn2+ and Ti4+ ions lowered the content of Fe3+ ions in the ferrites, which reduced the magnetocrystalline anisotropy constant |K1| and thus diminished the anisotropy-induced linewidth (ΔHa). Besides, the dielectric loss of the material decreased with increasing Zn-Ti substitution amounts (x) due to the reduction of Fe2+ ion content. As a result, when x = 0.35, the FMR linewidth was decreased from ∼251 Oe to ∼97 Oe, and the dielectric loss was greatly reduced from >100×10−4 to ∼3.82×10−4 in the ferrites. The material also exhibited excellent properties including high saturation magnetization (∼3913 Gauss), high Curie temperature (∼304 °C), and low coercivity (∼2.05 Oe).

An analysis of qualifications and requirements for geographic information systems (GIS) positions in the United States

AbstractAs the demand for geospatial analytics continues to grow, geographic information systems (GIS) professionals are needed to build, operate, and maintain GIS technologies, data, and software to provide geospatial insights for modern industries and organizations. To best train the next generation of GIS professionals, an understanding of qualifications and requirements of GIS positions is needed. Thus, this work analyzes 508 GIS positions, grouped by position type (analysts, developers, educators, managers, specialists, technicians) to provide insights on key pre‐requisite requirements, such as education, experience, certifications, soft communication skills, programming skills, and knowledge of GIS or IT. In general, possession of a bachelor's degree in GIS, geography, or computer science, prior professional experience, and knowledge of GIS and IT software were common pre‐requisites for most GIS roles. Soft communication skills were also frequently desired for GIS roles. We also found that some position requirements tended to vary by position type, such as manager and developer roles requiring on average 5 years or higher prior experience, while analyst, specialist, and technician roles had much lower experience and education requirements. Higher education institutions and GIS training programs should note the desired requirements for GIS position types and continue to refine programs and develop pathways for success for aspiring GIS professionals.

Legal regulation of information processes within the framework of preventive SMART monitoring

The purpose of this study is to analyze the legal problems that arise during implementation of preventive SMART monitoring in the financial and budgetary sphere, identify conflicts and develop recommendations on the correct application of legal norms during preventive smart control. We will not consider the general requirements for state information systems and procedures for collecting and processing information established by financial legislation, legislation of the Russian Federation on information, information technology and information protection, legislation on security, legislation of the Russian Federation on state and other legally protected secrets. The study will focus on aspects of regulating the procedures for collecting and processing information used directly during the preventive SMART control. The subject of the study is both the current legal norms and legislative initiatives on amendments to the Budget Code of the Russian Federation, as well as the information procedures themselves that exist during SMART monitoring. To conduct the research, a methodology was used, including an analytical review of the regulatory legal framework, draft regulatory legal acts and scientific literature on the subject of research, generalization and systematization of data, and the formation of proposals to resolve the identified problems. The main conclusions of the conducted research are: basic information relations within the framework of the implementation of preventive SMART control procedures in the financial and budgetary sphere are currently regulated by legislation and do not need further improvement; legislative work is required to improve the legal mechanism governing information processes using artificial intelligence, big data processing, and the introduction of intelligent agents; all innovations are proposed to be implemented only after a comprehensive assessment of their regulatory impact; additional regulatory consolidation is required by the mechanism of openness of all elements and procedures related to preventive SMART monitoring.

TECHNOLOGICAL AND TACTICAL SUBSYSTEMS OF THE INTELLIGENT MANAGEMENT INFORMATION SYSTEM (ON THE EXAMPLE OF AN OIL AND GAS CORPORATION)

Providing Ukraine with its own oil and natural gas is one of the main tasks of the national economy. The possibility of development of the oil and gas industry is primarily determined by the volume of explored and mined resources. Since the existing explored reserves will not ensure the growth of oil and gas production, it is necessary to increase the amount of investments in the exploration and development of new deposits and hydrocarbon deposits with the aim of increasing their reserves and further growth of production, which requires the adoption of management decisions, which are characterized by increased technological and economic risk, uncertainty.
 Taking into account the main reasons for the decline in oil and gas production in Ukraine, the specifics of the industry and the requirements for information systems in the oil and gas industry, it can be argued that the use of intelligent technologies not only at the strategic, but also at the tactical and technological levels of management - is one of the keys to success in creating/reengineering, implementation and effective use of management decision support systems.
 The scientific and practical results presented in the article regarding the innovative configurations of architecture and design, proposed intellectual methodology for tactical and technological subsystems of the corporation management information systems. The above-proposed solutions - should be taken into account when reengineering corporate information systems not only in the oil and gas industry in Ukraine [1-3]. 
 Moreover, the obtained results are relevant and applicable not only for local companies, but also for international corporations on emerging markets in the context of global and regional macroeconomic and military crisis phenomena.

An integrated fuzzy adjusted cosine similarity and TOPSIS based recommendation system for information system requirements selection

Selecting the requirements for an information system based on their ranking values is one of the critical steps in software development. Various methods for computing the ranking order of the requirements have been developed using multi-criteria decision-making methods. This study shows selecting the requirements for different software releases using a recommendation system is an unresearched problem. We present a recommendation system (PRecSys) for computing the ranking order of the requirements in an information system using fuzzy-based adjusted cosine similarity measure and collaborative filtering to recommend the requirements to stakeholders with similar interests. The ranking order of the information systems requirements in PRecSys is computed using the fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The applicability of PRecSys is discussed by considering the requirements for a library information system. The PRecSys is compared with PHandler, an expert system for choosing the requirements, based on the following criteria: agreement measure, the number of judgments by decision-makers, and time complexity.

Teaching Case: Read to Win: Using the Game-based System Design Framework to Gamify a Summer Reading Program

The use of gamification for organizational initiatives, such as increased foot traffic and customer engagement, is on the rise. Given this, recent information systems graduates may find themselves on project teams aimed at making decisions about gamification efforts. Currently, information systems curriculum doesn’t typically address the use of specific frameworks to design and document requirements for a game-based information system to meet a business need. This teaching case exposes students to the use of the Game-based System Design Framework in combination with the Game-based System Design Diagram to enhance student learning around the design and documentation of a gamified information system. This case could be used in an undergraduate or graduate program in either a systems analysis and design or a capstone course. The use of this case assumes that students have a basic understanding of business requirements gathering and project scope statements. Additionally, in order to develop a solution to this case, it must be used in conjunction with the article “All Work and All Play? A Framework to Design Game-based Information Systems” (Barber et al., 2021).

User Requirements in Enterprise Resource Planning Systems Adoption: A Case of Botswana’s Higher Institutions

ERP systems are the largest software applications adopted by universities, along with quite significant investments in their implementation. However, unlike other applications, limited research has been conducted regarding the application of this system in higher education in Botswana. This study aims to identify user requirements in the adoption of enterprise resource planning (ERP) systems in Botswana’s higher education institutions. This study was conducted in three higher education institutions in Botswana. This study adopted the quantitative methodology of using surveys to understand ERP adoption in higher education and proposed a model that could be used to guide business information systems requirements to appropriate ERP systems in a higher educational environment. Based on the findings, the study proposed a conceptual model of ERP system adoption in higher education institutions using six success dimensions. The six success dimensions are user requirements, user satisfaction, information quality, service quality, institutional impact, system quality, and faculty/management impact. Only information quality was rejected from the model. The six success dimensions are the basis through which a higher education institution can understand user requirements in implementing an effective ERP.

Machine-Learning-Based Password-Strength-Estimation Approach for Passwords of Lithuanian Context

In an information-security-assurance system, humans are usually the weakest link. It is partly related to insufficient cybersecurity knowledge and the ignorance of standard security recommendations. Consequently, the required password-strength requirements in information systems are the minimum of what can be done to ensure system security. Therefore, it is important to use up-to-date and context-sensitive password-strength-estimation systems. However, minor languages are ignored, and password strength is usually estimated using English-only dictionaries. To change the situation, a machine learning approach was proposed in this article to support a more realistic model to estimate the strength of Lithuanian user passwords. A newly compiled dataset of password strength was produced. It integrated both international- and Lithuanian-language-specific passwords, including 6 commonly used password features and 36 similarity metrics for each item (4 similarity metrics for 9 different dictionaries). The proposed solution predicts the password strength of five classes with 77% accuracy. Taking into account the complexity of the accuracy of the Lithuanian language, the achieved result is adequate, as the availability of intelligent Lithuanian-language-specific password-cracking tools is not widely available yet.
