Opis:
W pracy przedstawiono wyniki eksperymentów numerycznych związanych z aktywnym wykorzystaniem masy termicznej budynku jako magazynu energii cieplnej, pochodzącej z tańszej taryfy nocnej. Element grzejny umieszczono w masywnej podłodze a do jego sterowania wykorzystano zaawansowane techniki sztucznej inteligencji. Uzyskano kilkuprocentowe obniżenie kosztów ogrzewania w stosunku do obecnie stosowanych systemów sterowania.
The results of the investigation of energy performance of massive building envelope with a heating element placed in the massive floor has been shown in the paper. The proposed control approach of floor heating system is based on the advanced artificial intelligent methods. The results show that the floor heating system has good thermal storage performance, which can be used to a night-running model to obtain energy-saving benefits efficient and economic running cost. Investigated algorithm shows a few percent potential to decrease energy cost, in comparison to typical used control systems.

Opis:
This scientific work is devoted to the processes of creating technologies, as well as the use of their mathematical representation in the form of models in the context of the formation and development of the intellectual capital of an enterprise. To select a goal, a vision was formed to prove or refute any possibility of using Markov's theory in practice, namely the creation of a stochastic model of the intellectual capital of an enterprise in monetary terms, which manifests itself in investments in intangible assets. As an initial model hypothesis, the statement is accepted that investments in the enterprise's intangible assets are a factor in the transformation of intellectual capital into the company's value. Based on the results of applying the stochastic Markov chain model, the potential profit of the company's intangible assets was estimated, the main elements of which were intellectual capital assets during the study. A matrix of transition probabilities has been formed and modeling of the limiting probabilities of the system states has been implemented. The necessary conditions and boundaries of the scope of the mathematical model are also determined. The mathematical method of modeling the company's intellectual capital proposed in the article allows determining the contribution of each of the structural components to the formation of the value of the enterprises intellectual capital, thereby making it possible to establish a current balance between all its elements, which contributes to a comprehensive study of the company's intellectual assets.

Opis:
District heating, which accounts for half of the EU's energy consumption, still relies heavily on fossil fuels. This causes emissions of dust and greenhouse gases and into the atmosphere and leads to negative climate changes. For this reason, European Union countries have been implementing a climate and energy policy for many years, which in the area of heating is aimed at making it more efficient and sustainable. This requires the introduction of low-carbon technologies and the reduction of fossil fuel consumption by increasing the share of renewable energy sources. Modern, efficient and smart heating systems should guarantee reliable heat supply while reducing the environmental impact. The article discusses the direction of change and development of district heating systems through the introduction of innovative technologies. The new generations of 4GDH and 5 GDH district heating systems are described and the benefits of their use are indicated. The concept of smart district heating networks, their structure and the advantages of their implementation are discussed. The possibilities of creating smart energy systems using renewable energy sources and heat storage technologies were also indicated. The activities of Polish district heating companies in the introduction of smart heat networks are presented, based on research conducted.

Opis:
This paper describes a new approach, the HeKatE methodology, to the design and development of complex rule-based systems for control and decision support. The main paradigm for rule representation, namely, eXtended Tabular Trees (XTT), ensures high density and transparency of visual knowledge representation. Contrary to traditional, flat rule-based systems, the XTT approach is focused on groups of similar rules rather than on single rules. Such groups form decision tables which are connected into a network for inference. Efficient inference is assured as only the rules necessary for achieving the goal, identified by the context of inference and partial order among tables, are fired. In the paper a new version of the language-XTT2-is presented. It is based on ALSV(FD) logic, also described in the paper. Another distinctive feature of the presented approach is a top-down design methodology based on successive refinement of the project. It starts with Attribute Relationship Diagram (ARD) development. Such a diagram represents relationships between system variables. Based on the ARD scheme, XTT tables and links between them are generated. The tables are filled with expert-provided constraints on values of the attributes. The code for rule representation is generated in a humanreadable representation called HMR and interpreted with a provided inference engine called HeaRT. A set of software tools supporting the visual design and development stages is described in brief.

Opis:
Biorąc pod uwagę fakt, że identyfikacja modelu dynamiki statku w warunkach eksploatacyjnych jest pracochłonnym procesem - w artykule zaproponowano konstrukcję algorytmu stabilizacji kursu statku bazującą na metodach sterowania inteligentnego. Podejście takie umożliwia syntezę algorytmu sterowania 'on-line' nawet w przypadku braku znajomości struktury modelu dynamicznego statku.
Taking into account that the ship dynamics' identification process is such an arduous task the paper proposes a ship course stabilization algorithm based on the intelligent control concept. Such an approach makes it possible for an on-line control algorithm synthesis even in the case of the absence of a ship's dynamical model structure.
