Abstract: Precise information and navigation monitoring in horizontal drilling is of great importance for oil
exploration and deposit discovery. The cost of the drilling process depends significantly on drilling precision. The
necessary drilling accuracy is provided by navigation and information-gathering instruments which need electrical
power in order to operate. Small available volume, long drilling times, vibrations, and high temperatures are
typical constraints for any power supply source used in downhole drilling. Downhole navigation and information-gatheringsystems become increasingly complex, with more strict demands for the parameters of their electrical power supply. Batteries and conventional power cables are the traditional and the most utilized power supply sources downhole. Both have significant disadvantages and increase the cost of drilling operations. Short lifespan of the batteries and high susceptibility to failure of the cables in the harsh downhole environment are the main motivators for further research in self-sustaining energy sources. Ideally, downhole navigation instruments and information-gathering sensors (e.g. pressure, temperature, etc.) need autonomous power supply with electrical energy produced in situ. This would improve significantly the efficacy of the entire drilling process.
This article presents a review of the existing and the emerging concepts related to utilizing the available energy
sources in downhole drilling. The advantages and the drawbacks of these energy-harvesting concepts are
discussed and compared to conventional power sources. Progress in the development of some of these concepts
is illustrated by industrial examples. Some fairly new approaches to electrical energy supply for the information
exchange downhole are also presented in order to inspire non-traditional research in this field.

Abstract: In the article features of new portable biosensor devices of "Floratest" family for express-diagnostics of
plant state in real time mode are described. The devices are developed and created in V.M.Glushkov Institute of
Cybernetics of NAS of Ukraine. Today these devices are used in precision farming and environment monitoring,
but new application of these devices is more challenging. Standard biosensor device can be used as part of data
acquisition systems or independently, but all measurements are made in manual mode (several measurements
per hour). The new one is wireless biosensor. The biosensors are integrated into sensor networks and used in
precision farming and environment protection. Proposed wireless biosensors have significant differences from
free-running devices. Wireless biosensors with radio transceivers are placed on test plants and data reading from
set of plants is executed at the same definitive time by remote mobile computer or other mobile tools, for
example, electric unmanned quadcopter. Due to it is possible to get hundreds of measurements from different
parts of planted area or woodland. Implementation of proposed biosensor devices with radio channel and sensor
networks on their base to agriculture and environment protection makes it possible to increase efficiency and
quality of agricultural products, and spare fertilizers, water and energy resources, timely protect plants from
infections and anthropogenic impact.

Abstract: Pattern recognition problem using properties of parts of a recognizable objects and relations between
them is NP-hard. That is why quick recognition of an object with many elements is a difficult problem. To
overcome such a difficulty the use of upper bound of steps for an algorithm solving such a problem based on

is investigated. An example of such a problem for which the use of these upper bounds of
complexity permits to decrease the time of its solution is presented.

a notion is useful for more adequate formalization of finite memory of computer intended for a program run.
Complexity of logic-mathematical properties proof of such program-functions is investigated. A predicate
language is introduced to formulate such a partial program properties. P-SPACE-completeness of elementary
theories under a finite signature based on such a kind of functions with the use of halting predicate and
predicates of conditional equality and conditional inequalities. This allows to use the first order language for
description of logic-mathematical properties of computer program-functions by extension of the used programfunctions by means of a special additional value in the case of infinite looping of a program-function. In many cases it allows to replace traditional mathematical notions of an algorithm by the offered notion of a programfunction in the framework of mathematical informatics.

of contemporary web threats is discussed at an agent/application level. Advantages and disadvantages of synthetic data mining methods are investigated, and obstacles are revealed to their application in contemporary
systems. Novel results for juxtaposing statistical vs. logical data mining methods aiming at possible evolutionary
fusions are described. Recommendations are made on how to build more effective applications of classical and/or presented novel (meta) methods: SMM, KALEIDOSCOPE, FUNNEL, PUZZLE, and CONTRADICTION. The usage of ontologies is investigated with the purpose of information transfer by sense. Practical aspects of agent plications, intrusion detection, intrusion prevention, cryptography applications, multiple software and other research results are mentioned aiming to show that intelligent and classical technologies should be carefully combined in one software/hardware complex to achieve the creative goals. It is shown that all the demonstrated advantages may be combined with other known methods and technologies.

Abstract:The issues being discussed in this article are the consequences of the use of specific (journal – or
article - and researcher-based) metrics (“bibliometric indices”) for assessment of the performance of scientists
and research proposals.The analysis is focused on the potential of the use of such indices to operate as a
mechanism for control over the production of knowledge.The methodology is based on the complexity of relationships between sciences as systems for production of knowledge and their surrounding social environment. In these interactions arise motives for control and impact over knowledge production. The effects of these motive
s are expanding mechanisms for control over sciences and the knowledge they produce. The impact of the control mechanisms distorts knowledge and co-generates non-knowledge. When societies use distorted knowledge they face expansion of the so called “new risks”.On this basis “bibliometric indices” are identified as co
mponents of larger (in many cases - supranational) system for control over knowledge production (sciences’ dyna
mics) and as generators of distorted knowledge and unexpected and negative consequences (new risks) for societies.

Аннотация: Рассматриваются SDL-спецификации распределенных систем с динамическим
порождением и удалением экземпляров процессов. Для них предложен метод трансляции в
модифицированные цветные сети Петри - иерархические временные типизированные сети (ИЧТ-
сети), в которых используется предложенная Мерлином концепция интервального времени.
Естественный подход к верификации основан на использовании формальных моделей, таких, как
конечные автоматы, сети Петри и их обобщения. При этом процесс анализа и верификации
упрощается. Данная работа описывает SDL-системы с таймерами, которые позволяют адекватно
представить значительный класс коммуникационных протоколов. Для них предложен метод
трансляции в модифицированные цветные сети Петри - иерархические временные типизированные
сети, в которых используются предложенная Мерлином концепция интервального времени. Алгоритм
трансляции SDL-спецификаций в сетевые модели системы SDLE реализован методом трансляции в
два этапа. Способ моделирования основывается на том, что в многоуровневом описании системы в
SDL позиция каждого экземпляра процесса в общей иерархии системы остается неизменной, что
позволяет описание системы транслировать в структуру сети, а экземпляры процесса
моделировать с помощью фишек. В результате работы алгоритма создается такая сетевая
модель, в которой в каждом месте будет содержать не более одной фишки, моделирующей
некоторый экземпляр процесса. Таким образом, если во время функционирования системы может
существовать n разных экземпляров любого процесса, то в каждом месте моделирующей его сети
может содержаться не более n фишек, причем каждая фишка будет соответствовать своему
экземпляру процесса. Это факт позволяет существенно повысить эффективность моделирования,
так как существенно уменьшает перебор вариантов связывания переменных.

Аннотация: Рассмотрена задача принятия решений в условиях неопределенности с одним
интервальным показателем качества сравниваемых альтернатив. Введено понятие иерархии
неопределенностей в множествах предлагаемых к сравнению альтернатив, показатели качества которых описываются различными представлениями интервальных оценок, – моно интервальными и поли интервальными. Из-за типичного для задач выбора в множествах интервальных оценок пересечения интервалов задача сравнения таких, «интервальных», альтернатив может быть решена только с учетом предпочтений лица, принимающего решение. В рамках введенной иерархии предлагаются некоторые подходы к сравнению интервальных альтернатив и связанные с ними способы описания предпочтений ЛПР. Анализируется возможность введения предпочтений на базе предложенного авторами ранее метода расчета коэффициента уверенности в истинности проверяемой гипотезы о предпочтительности той или иной альтернативы. Рассматриваются возможности сравнения интервальных альтернатив и описания предпочтений посредством функций полезности, отражающих три основных вида предпочтений ЛПР, - безразличие к риску; постоянную
несклонность к риску и постоянную склонность к нему. Здесь проводится также сопоставление точечных оценок, эквивалентных сравниваемым интервальным, которые рассчитываются в рамках аппарата функций полезности («детерминированные эквиваленты»), с оценками «пессимизма – оптимизма» Гурвица. Показано, что в обоих этих методах результатами сравнения выступают характерные для многократно повторяющихся ситуаций осредненные индикаторы, используемые затем для описания предпочтений, что не всегда адекватно содержанию решаемых задач. В связи с этим предложен новый метод сравнения интервальных величин и описания предпочтений, сравнение оценок и задание предпочтений в котором осуществляется на основе сопоставления «гарантированных» значений разностей показателей качества сравниваемых альтернатив, трактуемых как случайные переменные, для выбранных экспертом уровней шансов реализации проверяемой гипотезы о предпочтительности. Этот метод сравнения и описания предпочтений, который свободен от использования осредненных величин, иллюстрируется для случая полученных авторами соотношений для функций распределения вероятностей разностей двух равномерно распределенных величин, заданных на сравниваемых интервалах. Дан численный пример сравнения интервальных альтернатив, осуществляемого разными методами.

Аннотация: В работе рассматривается новый подход, ориентированный на ретроспективный
анализ результативности научных проектов. Подход позволяет находить интегральные показатели оценки результативности научных проектов, используя методы группового вербального анализа решений и теорию мультимножеств. Рассмотрено применение предложенного подхода для выявления наиболее результативных научных проектов в Российском фонде фундаментальных исследований. Проведен многокритериальный анализ результатов, планируемых при подаче заявки на проект, промежуточных в ходе выполнения проекта и итоговых при завершении проекта.
Ключевые слова: групповой вербальный анализ решений, интегральный показатель оценки, результативность научного проекта, ретроспективный анализ
