Opis:: The concept of tourism clusters is becoming central within the tourism development planning process and the EU perceives cluster arrangements as the preferred form of introducing innovations in different economic fields, including tourism. The Polish Tourism Organization (POT) is to launch the subprogram aimed at the commercialization of the tourism product and intensification of SMEs’ integration processes (vertical and horizontal ones), which shall boost the innovativeness of Polish tourism regions and enterprises. The main purpose of this article is to find rationale for tourism cluster formation in Polish TDAs and to formulate the definition and main attributes of the tourism cluster. The problem of clusters’ impact on SMEs’ productivity and the destinations competitiveness will be discussed on the basis of economic theory using the case study and the field work method as well as the literature study.

Opis:: The article presents the path of evolution followed by contemporary research institutions. Similarly to business organizations, colleges and universities also evolve toward better access to the broadly defined resources (both tangible and intangible) and development of scientific potential. Consequently, universities strive for a significant place in national and transnational economies. It is a task that requires them to introduce organizational changes. One of these changes, increasingly noticeable no less, is being open to cooperation and willingness to establish relationships based on cooperation. Technological advancement provides, in this regard, a number of solutions and facilities willingly applied by research institutions and their representatives. The authors of the publication, based on the conducted studies, point to the need of establishing cooperative relationships that exceed the boundaries of the organization and to the advantage of this solution in the implementation of scientific and research projects.(original abstract)

Opis:: One of the most challenging research fields in which research community has taken a very active role is focused on trying to bring the features of wireless networks into line with the traditional wired solutions. Given the noisy and lossy nature of the wireless medium, it is more difficult to provide a comparable Quality of Service (QoS) and Reliability over wireless networks. This lack of reliability avoids the use of wireless solution in scenarios under harsh environment and mission-critical applications. In this paper we propose an inter-node collaborative schema with the aim of improving the achievable QoS level for multicast streaming, through the use of Network Coding and the algebra it is based on. We also present an implementation of the described algorithm on the OPNET discrete event simulation tool. Experimental results highlighting the performance achieved by the proposed algorithm and its improved efficiency as compared to other solutions are described.

Tytuł:: EARPC – Energy Aware Routing Protocol for Cooperative MIMO Scheme in WSNs

Opis:: Wireless sensor networks are typically operated on batteries. Therefore, in order to prolong network lifetime, an energy eﬃcient routing algorithm is required. In this paper, an energy-aware routing protocol for the co-operative MIMO scheme in WSNs (EARPC) is presented. It is based on an improved cluster head selection method that considers the remaining energy level of a node and recent energy consumption of all nodes. This means that sensor nodes with lower energy levels are less likely to be chosen as cluster heads. Next, based on the cooperative node selection in each cluster, a virtual MIMO array is created, reducing uneven distribution of clusters. Simulation results show that the proposed routing protocol may reduce energy consumption and improve network lifetime compared with the LEACH protocol.

overview
Opis:: We chronicle the research on the fusion technology of neural networks and fuzzy systems (NN+FS), the models that have been proposed from this research, and the commercial products and industrial systems that have adopted these models. First, we review the NN+FS research activity during the early stages of their development in Japan, the US, and Europe. Next, following the classifi- cation of NN+FS models, we show the ease of fusing these technologies based on the similarities of the data flow network structures and the non-linearity realization strategies of NNs and FSs. Then, we describe several models and applications of NN+FS. Finally, we introduce some important and recently developed NN+FS patents.

Opis:: Faithfull detection of non-utilized spectrum hole in available channel is a crucial issue for cognitive radio network. Choosing the best available channel for a secondary user transmission includes settling on decision of accessible choices of free frequency spectrum based on multiple objectives. Thus channel judgment can be demonstrated as several objective decision making (MODM) problem. An ultimate goal of this exploration is to define and execute a technique for multiple objective optimizations of multiple alternative of channel decision in Adhoc cognitive radio network. After a coarse review of an articles related to the multiple objective decision making within a process of channel selection, Multiple Objective Optimization on the basis of the Ratio Analysis (MOORA) technique is taken into consideration. Some important objectives values of non-utilized spectrum collected by a fusion center are proposed as objectives for consideration in the decision of alternatives. MOORA method is applied to a matrix f replies of each channel alternatives to channel objectives which results in set ratios. Among the set of obtained dimensionless ratios, all the channel alternatives are ranked in descending order. In MOORA, channel choices with moderate objectives can top in ranking order, which is hardly conceivable with linearly weighted objectives of the different channel by using different decision making technique.
