    This paper discusses tactical readiness as a complex of knowledge, skills and habits for the application of tactical means and methods of action in extreme conditions, individually and in small groups and formations on the enemy’s territory, or in situations when being surrounded or have fallen into captivity, escape from captivity and from the opponent’s territory under a complex impact on their part.

    This paper examines the particular nature of the tactical and fire training of the special units of the Bulgarian Army and the Ministry of Interior and the ways of improvement.

    The complex use of tactical and shooting habits is a foundational element in practice when performing special tasks. The skillful use of the right solutions in extreme situations implies the use of all types of firearms at different distances in the course of psycho-physical loads under the influence of distracting factors, combined with the use of techniques of hand-to-hand combat and special means. Along with this, the personnel of these units should be able to move tactically, taking into account the peculiarities of the surrounding environment and to use the firearms effectively.

    This paper presents the developed domain ontology of the equipment in manufacturing systems in order to be used in the field of reconfigurable manufacturing systems (RMS). The ontology meets the requirements of the meta-class "Equipment", which is part of the developed meta ontology based on the standard for integrated systems for the production and management IEC / ISO 62264. The article explains various properties and class restrictions of the developed ontology. Web Ontology Language (OWL 2) and Protégé 4.3 as an editor and knowledge acquisition tool are used. Special attention is given to the use of ontology reasoning to infer additional information from the facts stated explicitly in ontology – an important feature, used to perform classification, sorting and assembly operations and consistency checking.

    в настоящата работа са представени редица методи за пресмятане на работния обем и теоретичния дебит на зъбни помпи с външно еволвентно зацепване. Разгледани са зависимостите, предложени от различни автори за определяне на тези показатели, като е извършено сравнително изследване на точността при определяне на работния обем за конкретна зъбна хидравлична машина, за която опитно са дешифрирани геометричните параметри. Резултатите показват значително отклонение от дадената заводска стойност на работния обем, като в някои случаи това отклонение надвишава 25%.

    The focus of this paper is the need to achieve energy efficient work regimes in the operation of actual pump systems, because of the impact which energy efficiency has on the utilization of electricity by a system. Some of the main factors influencing the efficiency of a system’s crucial elements also have been examined. A quick and easy method for a quantitative assessment of a pump system’s efficiency also has been presented. The reliability of this methodology has been tested and confirmed. In conclusion, a method for the theoretical determining of the effective work regimes for a centrifugal pump with a trimmed impeller has been given.
