This paper explores the comparative analysis of the financial controlling, who is a result from the common controlling concept and the financial management. In the specialized literature, financial controlling is seen as an innovative approach to financial management. It is often presented as the most promising instrument of financial diagnostics. Generally speaking, financial controlling is seen as a process of managing the company`s assets which are valued in monetary measures. The difference between the financial management and the financial controlling is that the second covers all functions of management, analysis and control of finances, aiming at maximizing their effective use and increasing the value of the enterprise. Financial controlling is often seen as a function of the common practice of financial management. Its objective is to preserve the financial stability and financial sustainability of enterprises operating in a highly aggressive business environment.

Внедрение стандартов цифровой радиосвязи в гражданской авиации происходит практически без взаимодействия с международными организациями по стандартизации в области телекоммуникаций. При этом цифровая связь используется в первую очередь для обеспечения безопасности полетов воздушных судов. По радиоканалу в вещательном режиме каждое воздушное судно передает информацию о своем местоположении, обеспечивая таким образом ситуационную осведомленность экипажей других судов и диспетчеров. Поскольку число пассажирских и грузовых судов растет, а кроме того, в последнее время многократно возросло число беспилотных судов,которые должны быть интегрированы в общее воздушное пространство, то назрела необходимость рассмотреть существующие стандарты цифровой авиационной связи и провести сравнительный анализ их параметров. В данной работе выполнен сравнительный анализ физического и канального уровней стандартов VDL mode 4 и 090ES,а также представлены критерии качества передачи данных с помощью технологии автоматического зависимого наблюдения-вещания. Сравнение проведено по результатам моделирования работы стандартов в условиях высокой загруженности воздушного пространства. Digital communication standards implementation in civil aviation is now performed practically without collaboration with international telecommunications standardization organizations. At the same time, digital communication is primarily intended to ensure the safety of aircraft flights. Each aircraft transmits its position report messages over a radio communication channel in a broadcast mode, thus providing situational awareness for other aircrafts and the air traffic control staff. Since the number of passenger and cargo aircrafts grows, and in addition, the number of unmanned aircraft that must be integrated into the common airspace has recently multiplied, it is time to consider the existing digital aviation communication standards and perform a comparative analysis of their parameters. In the article, a comparative analysis of the physical and link levels of the VDL mode 4 and 1090ES standards was carried out. The ADS-B data transfer quality evaluation criteria are proposed. The VDL mode 4 and 1090ES standards modeling results in conditions of high airspace congestion are compared.

The realization that the directors occupy important position in corporate governance, and as business men and women, cannot be prevented from having dealings with the company, demand a close scrutiny of corporate transactions in which they are directly or indirectly involved or have an interest to ensure that such interest is not placed above their duty to the company. One of the ways in which the law strives to achieve this balance is by imposing a duty on the director to disclose to the board any interest he has in company’s transactions. This requirement which was previously governed by the common law and the company’s articles, is presently increasingly finding a place in companies statutes in different jurisdictions. The paper examines, through a comparative analysis, the provisions on the duty of the director to disclose interest in company’s transactions in South Africa and United Kingdom with the aim of discovering the extent to which the statute in both jurisdictions upholds the common law prescriptions. The paper argues that the need for transparency in corporate governance and the preservation of the distinct legal personality of the company demand that the duty to disclose interest should be upheld even in those cases of companies run by a sole director.

Chapter 4 of the new Israeli Contracts (General Part) Law, 1973, introduces the concept of a contract in favour of a third party, while granting express recognition to the right of a third party beneficiary. Even those, (including the author) who maintain, that the right of a third party beneficiary could and should be derived, even before the commencement of the new Law, from the general principles and premises of the old Israeli law of contract, cannot fail to see in the above-mentioned chapter an important innovation in the Israeli legal system.This paper is a comparative analysis of the institution of third party beneficiary. The analysis will consist of a presentation and critical examination of the central concepts and doctrines involved in the institution under discussion, and it will be combined with a comparative survey of the arrangements adopted in various legal systems. The choice of this approach stems from the particular circumstances of the new legislation.While in most countries, comparative legal research is a luxury, in Israel it is a necessity. The new legislation in private law is inspired to a great extent by Continental codifications. As far as the law of contract is concerned, Israel is now in the process of becoming a “mixed jurisdiction”: departing from the common law tradition and technique, and heading towards an independent body of law, derived from various sources, mainly Continental in both substance and form.

The substantiation of parameters of the 3D observation system is considered from the perspective of the Kirchhoff migration. At the first step of this transformation, on the basis of diffraction transformation on a gather of CSP, the problem of wavelet extraction reflected from specified points of the medium (image points) is solved. The characteristic of the directivity of this transformation is determined by parameters of the arrangement of devices. At the second step, summation is performed by gathers of the common image point (СIP). The distribution density of the observation system sources determines the stacking fold by CIP. In the process of selecting survey parameters, the comparative analysis of equivalent observation systems with the same data properties for the migration task, but with different parameters of the observation system, is of great important. The relationship between the step of common midpoints of the observation system and the step of traces of resulting images of the medium is discussed. The Gaussian beam migration algorithm is considered as a method for solving the problem of constructing an image of the medium that correctly takes into account the irregularity of the initial data.
