UAS in the Airspace: A Review on Integration, Simulation, Optimization, and Open Challenges

Air transportation is essential for society, and it is increasing gradually due to its importance. To improve the airspace operation, new technologies are under development, such as Unmanned Aircraft Systems (UAS). In fact, in the past few years, there has been a growth in UAS numbers in segregated airspace. However, there is an interest in integrating these aircraft into the National Airspace System (NAS). The UAS is vital to different industries due to its advantages brought to the airspace (e.g., efficiency). Conversely, the relationship between UAS and Air Traffic Control (ATC) needs to be well-defined due to the impacts on ATC capacity these aircraft may present. Throughout the years, this impact may be lower than it is nowadays because the current lack of familiarity in this relationship contributes to higher workload levels. Thereupon, the primary goal of this research is to present a comprehensive review of the advancements in the integration of UAS in the National Airspace System (NAS) from different perspectives. We consider the challenges regarding simulation, final approach, and optimization of problems related to the interoperability of such systems in the airspace. Finally, we identify several open challenges in the field based on the existing state-of-the-art proposals

Auditoria contínua de dados como instrumento de automação do controle empresarial

Business activities and business processes in the corporate world are technology-dependent. Such activities and processes drive the development of new audit techniques to investigate possible systemic failures that could affect the internal controls of companies. In this way, the need for automation of auditing tests led to the development of the concept and implementation of projects for continuous data auditing in the enterprise environment. This article evaluates the major critical issues for the construction of continuous data auditing, considering the use of information technology and computer assisted audit techniques. Four basic premises were formulated based on the theoretical foundation. From them eight propositions and eleven critical aspects were derived, which were placed in a proof of concept, through a multiple case study in the Brazilian business scenario. The main findings of this research were the critical aspects for the construction of continuous data auditing, originated in theoretical foundation and corroborated by the results of a multiple case study, which will serve as drivers for the initialization of continuous auditing projects as well as for their restructuring
