    Opis:
    The paper aims to present an empirical application of an originally developed model for corporate potential innovativeness assessment and comparison. The proposed model provides a framework for combined static and dynamic potential innovativeness assessment with the use of fuzzy logic. Fuzzy logic is used to assess corporate potential innovativeness from two perspectives: resources conditioning innovation activities in an enterprise, and the engagement of an enterprise in their continuous development. In this context, selected companies from the information technology sector listed on the Warsaw Stock Exchange were examined. The need for corporate innovativeness measurement and evaluation for management purposes arises from its growing importance in building enterprise value and achieving long-term competitive advantage. The proposed model enables the fairly current and good orientation in both general and a more in-depth innovativeness potential level of the assessed enterprises. This can be the basis for various comparison analysis and managerial decisions regarding e.g. innovation management as well as managing corporate image and reputation.

    Opis:
    Purpose: The main reason for developing the model was to fulfil the gap in the scope of synthetic/aggregate measure of corporate innovativeness in terms of company’s results in this area and their impact on its performance. Design/methodology/approach: In the proposed concept two aspects have been considered: quantitative and qualitative results of company’s innovation activity (i) and impact of this results on financial performance of company and its efficiency (ii). Due to the fact, that access to information on innovative activities results of companies is highly diversified, proposed model provides two versions to use: one, more general, based on public sources of data (Public Data Approach) and one, more detailed, based on data which should be collected through survey research (Survey Data Approach). The basis for corporate resultant innovativeness model creation was an assumption, that the ultimate market success of the company is not determined by how many innovative solutions it implements and introduces to the market and with what force it does it, but how these solutions will be accepted by the market and what economic benefits the company will receive due to them. Findings: Proposed methodology of innovativeness assessment gives a chance to eliminate several key shortcomings of the so far used methods and concepts of corporate innovativeness measurement and assessment. Research limitations/implications: Input data accessibility, development of knowledge (rules) bases needed to perform fuzzy inference. Practical implications: Presented model gives an opportunity to assess and compare enterprises in terms of their resultant innovativeness and then to assess the impact of this innovativeness on their performance. Social implications: Assessments generated by presented model can be basis for managerial decisions inside the assessed enterprise or investment decisions of investors in the capital market. Originality/value: Original approach for aggregate corporate resultant innovativeness assessment that eliminates several weaknesses of methods used so far.

    Opis:
    Research background: Since the Internet bubble, which took place at the turn of XX and XXI century, on the global capital markets, including Poland, one may note a growing interest in companies focusing on innovations and innovativeness. The main driver of this interest is the belief that in a longer term innovations and expenditures on research and development will translate into an increase in competitive advantage, financial results, and subsequently also the market value of companies. On the other hand, the attention should also be paid to the fact that innovative activity has also another, darker, side, which is identified with the far-reaching uncertainty about its final effects and the possibility of incurring losses, especially in financial dimension. At the same time, it should be noted that implementation of investment strategy regarding the shares of innovative companies is quite troublesome because of the lack of unified methodology for assessing corporate innovativeness and large information diversity in this area. Purpose of the article: The investment efficiency analysis of investment strategy regarding shares of companies perceived to be innovative with simultaneous focusing on the different cases of situation development in time. Methods: The research was carried out for companies listed on the main market of the Warsaw Stock Exchange, taking into consideration various time ranges of investment. The efficiency analysis of this investment strategy was conducted in the risk-return outlay with the use of such measures as: accumulated rate of return, arithmetic average rate of return, standard and semi-standard deviation, as well as coefficients of variation and semi-variation of rate of return and their inverses. Findings & Value added: The obtained results show that in shorter periods of time, inves-tors buy expectations connected with innovative companies and therefore, the efficiency of investment in their shares is relatively high, but in the longer term expectations are revised by companies' financial results, which in turn often negatively affects the investment efficiency.

    Opis:
    Taking as a basis for discussion the Schumpeter’s innovation theory, this paper analyses the relationship between enterprises activity in the field of research and development, and their efficiency at the core business level. This analysis was performed in two ways – with the assumption shift in time between research and development activities and companies business efficiency, and without it – using the Spearman’s rank correlation coefficient. The sample was accounted for 252 companies from the technology sector, whose shares are traded on NYSE or NASDAQ, and the analysis time period consisted of three years (2011–2013). The results obtained in the course of analysis generally indicate lack of strong relationship between distinguished categories. A noticeable, but only at moderate level, positive correlation was found in both considered approaches only in respect of the relationship between the intensity of expenditures on research and development or y/y change of these expenditures and gross margin on sales. Therefore, it seems to be relevant to extend this research at least in such directions as: identification and characterization of factors determining efficiency of companies research and development activities, as well as examination considered relationship taking into account business diversity within the sector and wider time shift between realized research and development activities and various measures of core business efficiency.

    Opis:
    New 40Ar-39 Ar isotope ages of mafic and felsic rocks from the contact zone of the Malopolska and Brunovistulian terranes are presented and discussed. A 40Ar-39 Ar age estimation of detrital muscovite from a Lower Devonian "old red" type sandstone drilled on the Malopolska side of this zone was also done. Our studies reveal that three events of Paleozoic magmatic activity took place in the study area. The oldest, late Emsian episode is recorded by a diorite from the core part of an intrusion penetrated by the Sosnowiec IG 1 borehole. A younger, Visean event is documented by a diabase cored in the borehole WB-137. Diabases from Niedwiedzia Góra and from borehole PZ-10, and a rhyodacite from borehole 16-WB gave early Permian (Artinskian-early Sakmarian) ages. The youngest, middle Sakmarian age was obtained for a diabase forming the external parts of the Sosnowiec IG 1 polycyclic intrusion. A diorite penetrated by the Sosnowiec IG 1 borehole was emplaced during the late Emsian extension that preceded the Lochkovian-Pragian? transpression related to the final docking and amalgamation of the Brunovistulian Terrane.

    Opis:
    Acceptance tests are usually created by a client after a part of a system is implemented. However, some methodologies propose the elaboration of test cases before implementing a system. This approach increases the probability of system implementation that fulfills requirements, but may be problematic for customers and testers. To allow acceptance testing in such conditions, we propose to define test cases by recording them on an interactive mockup (a low detailed user-interface prototype). The paper focuses on Test Description Language, a notation used to store test cases.

    Opis:
    This paper describes the use of simulation in the design of agricultural machinery. It allows to define the kinematic behavior of the designed machine. 3D models of tractor and cooperating universal tool for strip tillage and model of cultivation aggregate with hitch to the drill were developed to conduct the kinematic analyzes. Simulation results are presented graphically on the graphs, which show the values of the measured parameters. The executed research defined reaction forces between machine and three-point hitch linkage of the tractor, the tractor stability and impact of changes in position of drawbar coupling parts on the selection of hydraulic cylinder. It was demonstrated the stability of the tractor when driving through the obstacle and the correct selection of the hydraulic cylinder, which ensures the correctness of the process of folding and unfolding.
    W pracy przedstawiono zastosowanie badań symulacyjnych w projektowaniu maszyn rolniczych. Pozwalają one określić zachowania kinematyczne projektowanej maszyny. Do przeprowadzenia analiz kinematycznych opracowano modele 3D ciągnika rolniczego oraz współpracującego z nim uniwersalnego narzędzia do uprawy pasowej oraz model agregatu uprawowego ze sprzęgiem do siewnika. Wyniki symulacji przedstawiono graficznie na wykresach, na których przedstawiono wartości mierzonych parametrów. W przeprowadzonych badaniach określono reakcje maszyny na TUZ ciągnika, jego stateczność oraz wpływ zmian położenia elementów sprzęgu na dobór siłownika hydraulicznego. Wykazano stabilność ciągnika podczas przejazdu przez przeszkodę i prawidłowy dobór siłownika, który zapewnia prawidłowość procesu składania i rozkładania.

    Opis:
    The paper presents application of the FEM method to develop universal carrying frames for agricultural machinery and their empirical verification. To perform stress analysis there were developed computational models basing on geometrical 3D models. Identification of strenuous of framework design was defined by adopting different load cases. In the nodes which revealed excessive stress levels, the frame structure was changed. In experimental research in real conditions the results of FEM stress analysis were verified. The verification showed that developed universal carrying frames for agricultural machinery are characterized by correctness of endurance structure and confirmed the appropriateness of the design solutions.
    Przedstawiono zastosowanie metody FEM do opracowania uniwersalnych ram nośnych maszyn rolniczych oraz i jej weryfikację empiryczną. Do przeprowadzenia analiz wytrzymałościowych opracowano modele obliczeniowe na bazie modeli 3D. Identyfikację wytężenia konstrukcji ram zidentyfikowano przyjmując różne przypadki obciążeń. W węzłach, w których odnotowano nadmierne poziomy naprężenia zredukowanego zmieniono konstrukcję ramy. W przeprowadzonych badaniach eksperymentalnych w warunkach rzeczywistych dokonano weryfikacji empirycznej wyników analiz wytrzymałościowych. Weryfikacja wykazała, że opracowane uniwersalne ramy nośne maszyn rolniczych cechują się poprawnością struktury wytrzymałościowej i tym samym potwierdziły poprawność przyjętych rozwiązań konstrukcyjnych.
