Opis:: The e-learning course is one of the most efficient and promising didactic policies. It must be grounded on the revision because it was proved that it enhances the longterm memory. However, human mind is not a uniform phenomenon. Each man memorizes and learns in a different manner. The purpose of the intelligent e-learning system presented in this paper is to teach orthography and this system is based on the multilayer neural network. Such structure enables a learner to adjust the crucial period between revisions to personal learning habits and policy.

Opis:: Within the road investments the very important element determining repeatedly the success of the whole project is an adequate information about the characteristics of the site, its load capacity, stability and the possible impact of geological characteristics that may interfere with subsequent service life, not only for the road surface itself, but also for the surrounded objects. The surface is incessantly influenced by geological characteristics, determining its durability and functional usefulness. The main aim of this paper is to answer the question how by the usage of modern technics for obtaining data it is possible to find a link confirming the characteristics of land on which the specific road projects are supposed to be carried out, or where these projects have already been accomplished, concerning their requirements with high accuracy of location and also the stability and durability of the ground. This article makes also an attempt to answer not only the question how to identify the construction of road surface, but also how to locate underground cavities, created or influenced by the flow of water, or due to geological structures characterized as an inconsistent ground. The results were supported with geophysical researches using GPR method, and also data collected with laser scanners.

Tytuł:: Models of IT project management implementation and maintenance

Opis:: The process of software development has become so dynamic that it nowadays requires more and more supporting tools. An organization which intends to have such tools implemented must take into account its possible future needs. Complex solutions usually offer greater variety of available options and functionalities but are costly to implement. This paper presents some models o IT project management together with the supporting software. Owing to applying the resource management policy at the stage of production and implementation one may assess the risk and identify potential threats. The discussed issues may shed some light on potential difficulties occurring at the particular stages of software production management whereas the conclusions may help people in charge choose the best model, including its implementation strategy. The first model are dedicated tools created from scratch and often preceded by the analysis of the existing solutions and the needs of the company and the customers. The second is to seek from the very beginning multifunction and complex tools for the big or well-developed IT systems providers. This article is to present the models regarding the IT project management (together with the related supporting tools) which are applied in the IT companies involved in providing the foreign customers with the bases of knowledge. On the basis of the experience gained while designing and developing dedicated software (by means of the above-mentioned tools) and its implementation one drew some conclusions concerning e.g., risk assessment; potential threats at every stage of the project lifecycle; improvement of the quality and production time of the software; reduction of the number of errors; improvement of the internal communication within the project team (it is the first step in the development of the design patterns). The patterns should help the managers choose the proper management model and related tools for the implementation and particular project tasks.

Tytuł:: Usage of lidar data in planning of wind turbines location

Opis:: The aim of this paper is to confirm the thesis that by the usage of laser scanning methods it is possible to find a link confirming the characteristics of swampy land on which the specific building projects are supposed to be carried, as well as their requirements in high accuracy of location and the stability and durability of the substrate. Visible to the naked eye, regular depressions in the ground may foretell the places of underground space, created or influenced by the flow of water or due to geological structures, characterizing the substrate as inconsistent. These spaces seriously affect the possibility of placing wind turbines. By using LIDAR high correlation is visible between the characteristics of the terrain model and the location of underground geological spaces that could endanger the constructions that will be formed in the area. While the construction is being built the ground emphasizes so much that wrong location can simply cause the collapse of the structure. The results were supported with geophysical researches, using three methods: ERT - electrical resistivity tomography, GPR - ground penetrating radar, and the seismic method.

Sparse Classification
Opis:: Automatic Speech Recognition is one of the hottest research and application problems in today’s ICT technologies. Huge progress in the development of the intelligent mobile systems needs an implementation of the new services, where users can communicate with devices by sending audio commands. Those systems must be additionally integrated with the highly distributed infrastructures such as computational and mobile clouds, Wireless Sensor Networks (WSNs), and many others. This paper presents the recent research results for the recognition of the separate words and words in short contexts (limited to the numbers) articulated in the Polish language. Compressed Sensing Theory (CST) is applied for the first time as a methodology of speech recognition. The effectiveness of the proposed methodology is justified in numerical tests for both separate words and short sentences.

Opis:: This paper concerns the possibility of using AGS15 capacitive inclinometers in the geodetic monitoring of slender structures. The basics of geometric monitoring have been introduced, and the features of inclinometers that can be used in these studies have been described. Main expectations towards them have been formulated. Three tests were conducted: (1) a few days' stability test of readings, (2) the test of inclinations controlled tachimetrically and (3) continuous survey of a physical object. It has been found that in order to obtain satisfactory results it is necessary to correct the readings due to the drift and the effect of temperature. The works conducted as part of described project work are not capable of identifying those indicators. To achieve them there were designed the system that support the acquisition and processing of the measurement and also the collection and transmission of results. In the conclusions authors stated that inclinometers AGS15 can be suitable for monitoring, but the works aimed at improving their performance should be undertaken.
