A planar inductive displacement sensor is implemented in a foot of humanoid robot. The sensor, which is composed of two sensor elements, is used to measure normal and tangential component of reaction force onto robot foot. The goal of this paper is to determine absolute error of acting point of contact force detection. The error is caused due to sensor element error introduced by assembling uncertainties and measuring nonlinearities of the sensor elements used for indirect measuring of the normal component of the force.

Computer networks are complex systems that provide the basic infrastructure for many diverse services. An efficient method for description of computer networks is useful for many appliances, for example network documentation, planning, analyses, management, etc. XML-based languages and XML technologies have been developed for many purposes, including the description of computer networks and data communications. In this paper we present the approach in using the XML-based language, called NNDL (Network Node Description Language) for creation of network node configuration files. Also, the application, called NodeConfigurator, based on NNDL is presented as well. These configuration files are used for configuring network nodes in virtual network laboratory based on virtualization technology.

The work presents a web-based control solution which can be effectively used with the electro-energy systems. The work gives a brief overview of the already known solutions in energy management systems and it proposes a new type of solution. The proposed solution enables remote management and monitoring of energy systems. The user interface of the remote management uses a web-based technology. One server side application provides the connection between the Web and the PLCs. In the proposed architecture the inputs and outputs of the PLCs are connected to the managed devices. The system allows for alternative realization of the control as well. Furthermore, it is important that it is possible to state a feedback of devices, even if it is not altered by the present management system. During the development of the system the aspect such as convenience has been taken into consideration, but a great emphasis was put on energy savings as well. Based on the experience the knowledge base has been set up. During the monitoring of the system, an expert module minimizes the total energy consumption, so that the system's functionality remains.

In this paper a mathematical model of optimal agricultural production plan is derived and applied on a small farm which is located in west Vojvodina. In order to construct a more realistic model of optimal crop distribution and deal with crop rotation and uncertainty, the modified Mean - Variance model is used.

Modern organizations and companies exist in time of progressiveness in almost all segments of life and work influenced by large, rapid and dynamic changes. In such conditions, business world is enforced to adapt to these changes. Character of resulting changes is such that leads to question the existing social theories, especially in the macroeconomic field. Project management is a new and specialized management discipline. The main goal of project management is an efficient project realization within the planned time and planned costs in the conditions of significant external and internal changes. In this paper we developed a fuzzy reasoning approach for a Postal company restructuring project management. We combined Fuzzy PERT method with Fuzzy Delphi for activity time forecasting and finding the critical path. This approach has been applied on a project of Serbian postal company restructuring and obtained results appeared as very consistent.

The authors consider microeconomic aspects of the state regulation of tax policies and subventions. The analysis includes the consideration of basic goals of the state intervention as providing budgetary revenues, influences on microeconomic situations, preference or non-preference of some market participant or social groups. The main point of consideration is on the analysis of impacts of instruments of the state intervention on the behavior and position of companies, market functioning and market equilibrium.

Complex data can often be represented in terms of random graphs or networks. Important features of real world networks can be described by a special class of random graphs called small-world networks. Small-world networks emerge in many contexts, from systems biology to distributed technological systems. Here we ask how the functional and structural properties of specialized real world networks are reflected in convergence-divergence properties of their edges and nodes. We introduced a novel metric called edge convergence degree and studied it on small-world networks generated according to different rules. The obtained results were compared with Erdős-Rényi random networks. We found that convergence degree sensitively distinguishes different models of random networks we studied.

Interval-valued functions and integration of interval-valued functions are important mathematical tools that play a crucial role in several practical areas, e.g., mathematical economics. This paper is focused on interval-valued measures based on pseudo-integration of interval-valued function. Some important characteristics of this type of measures, such as absolute continuity of type I and type VI, are investigated.
