    • SOFTWARE DESIDN

      pg(s) 11-14

      As a process, software design is the software engineering life cycle activity in which software requirements are analyzed in order to produce a description of the software’s internal structure that will serve as the basis for its construction. A software design (as the result) describes the software architecture-that is, how software is decomposed and organized into components-and the interfaces between those components.

      In the report they have explained breakdown of topics of process of software design.

    • THE PROBLEM OF OVERLAPPING PROJECT ACTIVITIES WITH INTERDEPENDENCY

      pg(s) 19-22

      This paper analyzes a simple project with two activities. The activities can be executed in a serial mode (separately), in a parallel mode (overlapping), or in a mixed mode (partly in a serial mode and partly in a parallel mode). There is interdependence between the activities and the duration-budget tradeoffs functions of the activities are defined differently for each execution strategy. The paper presents a deterministic duration-budget tradeoff model that takes into account the interdependence between the activities in order to determine the optimal execution-mode and the budget distributions among the project activities. A stochastic extension of the proposed model is also considered. The presented analysis can help project managers and practitioners in choosing the optimal overlapping strategy for different objective functions and constraints.

    • SUMMARY OF INNOVATION MODELS ON A COMPANY LEVEL – CREATING A FRAMEWORK FOR AN INNOVATION MODEL THAT WILL INCREASE A COMPANY’S INNOVATION ACTIVITY

      pg(s) 23-26

      There are six known and generally accepted generations of innovation models. Innovation models transform from simple, linear models, to integrated and networking models that are dynamic and interactive. Each generation of innovation models is presented in this paper with their characteristics as well as drawbacks. The main goal of this paper is to show the transformation path of innovation models and create a framework for a new innovation model on a company level, that could be used by companies to increase their innovative activity and performance. Innovation models define the innovation process and its phases. The framework for the new innovation model includes feedback that was lacking in the first and the second generation of innovation models, but is included in the other generations. It also includes integrated and networking activities which are a characteristic of the third and fourth generation of innovation models. Another component of the model is the usage of information and communications technology (ICT) to facilitate the process of innovation, which is one of the characteristic of the fifth generation of innovation models. It uses a process approach and is based on the open innovation model, which is the signature model from the sixth generation of innovation models and best represents the complex system and characteristic of innovation. The model is supposed to help companies generate innovative ideas and select them through a predetermined process with four main components that act as control points. The purpose of this model is to create a continuous culture for innovation and to set up official procedures. These will help companies to accomplish their innovative ideas and activities.

    • TOP INNOVATION IN MANAGEMENT OF AGRICULTURAL ACTIVITIES (EFFECTIVE BIOLOGICAL AGRICULTURE UNDER IRRIGATION AND PROTECTING THE ENVIRONMENT)

      pg(s) 27-30

      The report deals with the perspectives for developing ecologically based biological agriculture in Bulgaria, the European Union and the other countries. Innovative technology (for computerized monitoring the soil water deficit and scheduling the irrigation) replaces the periodical local (point) measurements of soil moisture. Its application helps to be realized appropriate energy level of soil moisture through ecologically accepted watering technique in each agricultural crop field. It ensures to be obtained the scientifically planned amount and quality of crop yield, saving over ten years on average 30 % of irrigation water and one third of nutrients added for plants.

    • ON REGULAR PARALLELISMS OF PG(3,5) WITH AUTOMORPHISMS OF ORDER 5

      pg(s) 3-5

      A spread is a set of lines of PG(n,q), which partition the point set. A parallelism is a partition of the set of lines by spreads. A regulus of PG(3,q) is a set R of q+1 mutually skew lines such that any line intersecting three elements of R intersects all elements of R. A spread S of PG(3, q) is regular if for every three distinct elements of S, the unique regulus determined by them is a subset of S. A parallelism is regular if all its spreads are regular.

      Regular parallelisms in PG(3,q) are known for any q ≡ 2 (mod 3) due to T. Penttila and B. Williams, 1998. In PG(3,5) these families of regular parallelisms are presented by two regular parallelisms with automorphisms of order 31 obtained early by A. Prince. Whether these are all regular parallelisms in PG(3,5) is an open question.

      There are four relevant groups of order 5 and in the present paper it is established that the regular parallelisms of PG(3,5) cannot posses any authomorphism of order 5.

    • AN APPROACH TOWARDS PLANNING OF ELECTRIC VEHICLES CHARGING INFRASTRUCTURE BASED ON VEHICLE AND TRANSPORT STRUCTURE

      pg(s) 31-35

      Electrical vehicles are in a new phase of development and utilisation. It has been a long time before such initiatives have taken place. In the meantime the transport as a whole (vehicles, roads, traffic, etc.) has been significantly changed. As expected the main role in this process globally, and regionally is taken by the biggest economies and companies. Besides the environmental priorities, the nature of transport which does not recognise borders enforces smaller economies and countries to adopt their policies in this area, and take chances of the development. This seems to be very complex process with number of challenges. Some of them are very specific for different countries, and it is up to the local researchers to recognize and deal with them. This paper addresses the problem of the infrastructure, i.e. developing of a network of charging stations. Since there are number of specific technical aspects accompanying electric vehicles (types of vehicles, range, charging limitations, price, etc.), the research has started with analysis of the vehicle fleet, road network, and intensity of the traffic in different areas of Republic of Macedonia. This picture is compared with technical characteristics of emerging electric vehicles on the market. That was the way to recognize advantages and disadvantages of use of electric vehicles as substitution of some of the vehicles in the actual fleet. Possible development of use of electric vehicles in the country had to be estimated based on foreign experiences, and such policies in the country. As a result an approach towards development of network of charging stations in Republic of Macedonia has been defined. There is an obvious need this view to be widely presented and discussed with a possible outcome to serve as contribution to the challenges similar countries will face soon.

    • PRESERVATION OF POLLUTION OF DANUBE RIVER WATERS

      pg(s) 36-37

      The preservation of ecological system of Black Sea is associated with care for the rivers which flow into it. Bulgaria makes efforts to implement high standards for preservation of the Danube River which represents unique water basin. The improvement of quality of its waters unites the efforts of the riverside countries which contributes for preservation of the ecological system of Black Sea.

    • IDEОMOTORIC TRAINING AS A TOOL FOR PROFESSIONAL RELIABILITY IMPROVEMENT AMONG POLICE OFFICERS

      pg(s) 41-43

      Professional activity of police officers is often related to extreme situations stimulating the emergence and development of stress conditions. Police officers, who were not trained in dealing with stress, in extreme situations, can act in a professionally inappropriate manner and put at risk (including risk of death) those involved in a situation, including police officers themselves, and deteriorate the efficiency of resolving the situation of offence. Lack of skills on how to cope with stress significantly undermines normal activity of police officers. The article discusses the theoretical basis of the authors’ developed ideomotoric training program designed for police officers, as well as its validation results. The program aims to decrease the negative consequences of being emotionally involved in stressful situations and to enhance the individual resistance to stress among police officers. The special attention is focused on professional reliability improvement among police officers resulting from participation in the ideоmotoric training program.

      pg(s) 6-7

      Creating 3D models of molecules and chemical compounds is a necessity in scientific work, which examines different states, structures, processes and interaction of molecules. This is done through the use of comprehensive 3D graphics programs as well as specialized applications containing and maintaining a database of ready-made models. The ability to work with good 3D graphics platform such as Blender combined with available resources of ChemSpider and Open Babel, builds a powerful system allowing the creation of highquality and realistic virtual models of molecules and chemical compounds.

    • MOLECULAR SIMILARITY IN THE FRAMEWORK OF A BIOISOSTERISM STUDY

      pg(s) 8-10

      Bioisosterism is a strategy of Medicinal Chemistry for the rational design of new drugs (bioisosterism is also known as quantum similarity). The success of this strategy in developing new substances which are therapeutically attractive has observed a significant growth in distinct therapeutic classes, being amply used by the pharmaceutical industry to discover new analogs of therapeutic innovations commercially attractive, and also as a tool useful in the molecular modification. In this work,the concept of quantum similarity in the signed particle formulation of quantum mechanics is introduced. This concept was suggested very recently and was studied for the particular case n=1. Therefore, we extend the mathematical expression of similarity to the case n>1, with particular attention to the differences brought in this new context.
