Opis:
Many studies have so far tried to examine the relationship between listening strategies and listening comprehension. However, it seems that none of them have focused on the effect of the test method on the findings. The present study has investigated the issue by having 55 English language learners respond to pictorial and non-pictorial listening test items with different response formats. The listening section of the Preliminary English Test (PET) and a 36-item listening strategies questionnaire were administered in the first session and after a week’s interval, the participants took a modified version of PET listening. The data were collected in a language laboratory. Several correlation and regression tests were run to investigate the relationships between listening comprehension as measured by the original and modified PET listening tests and metacognitive, cognitive and socio-affective listening strategies. The results showed that L2 learners’ use of metacognitive listening strategies is the strongest predictor of listening performance. In addition, the findings indicated that the relationship between the use of listening strategies and listening performance is mediated by the kind of test method which is used for measuring L2 listening. Directions for future research and implications for practice are presented.

Opis:
As part of growing efforts to understand factors affecting c-test this study aims to investigate the effect of text authenticity on the performance of Iranian EFL students in a C-Test. The C-Test is an integrative testing instrument that measures overall language competence, very much like the cloze test. In this study the rule of two has been applied: "the second half of every second word has been deleted, beginning with the second word of the second sentence; the first and last sentences are left intact" (Katona and Dornyei 1993: 35). The research involves 60 college students in their third year, majoring in English Literature at Ershad-Damavand College. This group were randomly selected applying multi-stage sampling. Since the present study intended to investigate the role of two different formats, i.e. authentic and inauthentic texts (text translated from Persian into English), two different tailored C-Tests were made to measure and compare the performances of the participants. Two C-Tests, one with Authentic Text and the other, with Inauthentic Text were administered to this homogenized group comprising 30 subjects. The findings of this study suggest that authenticity has an effect on the performance of learners in c-tests and we should control this variable while devising a c-test.

Opis:
GNSS systems are susceptible to radio interference despite then operating in a spread spectrum. The commerce jammers power up to 2 watts that can block the receiver function at a distance of up to 15 kilometers in free space. Two original methods for GNSS receiver testing were developed. The first method is based on the usage of a GNSS simulator for generation of the satellite signals and a vector signal RF generator for generating different types of interference signals. The second software radio method is based on a software GNSS simulator and a signal processing in Matlab. The receivers were tested for narrowband CW interference, FM modulated signal and chirp jamming signals, and scenarios. The signal to noise ratio usually drops down to 27 dBc-Hz while the jamming to signal ratio is different for different types of interference. The chirp signal is very effective. The jammer signal is well propagated in free space while in the real mobile urban and suburban environment it is usually strongly attenuated.

Opis:
The purpose of the paper is to analyse the issue of a test method in economics. It calls for the necessity of adopting a methodological approach that will be flexible and cognitively inspiring, which is a prerequisite to establishing the foundations for economics, its development and effectiveness in clarifying social and economic phenomena. Currently believed to be a complex (both theoretical and empirical), and inductive-deductive science, economics fails to possess binding methodological arrangements. Therefore, when looking for good solutions, scholars propose universal pluralism, which lets them expand the research apparatus within defined, yet not tightly logical structures.

Opis:
By combining experimental tests and numerical simulations, the output pressure of JO-9c explosive was measured for a series of small-sized charge diameters, and qualitative rules and a quantitative model were obtained for the influence of charge diameters upon the JO-9c explosive output pressure. Results show that a small-sized charge diameter has a significant influence on the output pressure; in addition, the closer the charge diameter gets to the JO-9c critical diameter, the greater is the effect. The limiting diameter of JO-9c is 5 mm, and the critical diameter is approximately 0.34 mm. The deviation between numerical simulation results and experimental values shows that the numerical simulation method can predict detonation pressure with 15% uncertainty in the study of detonation rules for small-sized charges.

W wyniku intensywnych badań, prowadzonych od wielu lat w licznych ośrodkach naukowych na świecie, polimerowe izolatory kompozytowe posiadają coraz lepsze właściwości i są coraz powszechniej stosowane w przesyłowych i rozdzielczych liniach elektroenergetycznych. W artykule przedstawiono metody badań umożliwiające ocenę elementów składowych izolatorów kompozytowych - materiałów osłonowych, rdzeni szkłoepoksydowych i powierzchni granicznych - decydujących o właściwościach elektrycznych izolatorów. Uwagę zwrócono również na metody przyspieszonych badań starzeniowych, w szczególności na badania odporności izolatorów na procesy starzeniowe rozwijające się w warunkach działania wysokiego napięcia oraz wody deszczowej i mgielnej. Przedstawiając osiągnięcia badawcze ośrodka wrocławskiego podkreślono celowość doskonalenia metod badawczych i stosowania w badaniach właściwych kryteriów oceny izolatorów.
Silicone rubber insulators produced nowadays have better and better properties as a result of intensive investigations conducted in many scientific centres in the world. Therefore they are more commonly used in transmission and distribution power lines. In this paper test methods enabling estimation of silicone rubber insulator components such as housing materials, glass-epoxy rods and boundary surfaces are presented. Chapter 2.1 of the paper is focused on standard tests of insulation materials. The first part of this chapter presents selected electric tests for determining the electric strength of insulation housing materials and tests of brittle cracking of glass-epoxy rods [18]. The second part presents long term ageing tests of insulation material (for example the long term test of water immersion). Chapter 2.2 deals with tests of rods and boundary surfaces. In the case of rods the most dangerous is unsealing the boundary surface between the fitting and housing, which is the result of water penetration along the rod [17]. The test of steep-front high voltage impulses allowing the detection of construction defects [26] is also presented. The High Voltage Laboratory of Wrocław University of Technology proposed the essential modifications of these tests. Chapter 3 of the paper is focused on accelerating ageing test of silicone rubber insulators. The tests in high voltage, clean fog and rain chambers that were elaborated in our High Voltage Laboratory are described. It is pointed out that the development of the new test methods of silicone rubber insulators results in better estimation of their properties.

Analiza wielokryterialna przedstawiona w artykule jest metodą oceny ważonej wspomagającej ocenę zdegradowania nawierzchni lotniskowych. Jej podstawa zawiera się w określeniu wielu kryteriów wyboru wariantu z uwzględnieniem różnych wag poszczególnych kryteriów. Istotnym czynnikiem, który ma wpływ na bezpieczeństwo wykonywanych operacji lotniczych jest właściwe zarządzanie lotniskami w oparciu o uzyskane w sposób systemowy informacje o stanie nawierzchni ich elementów funkcjonalnych. Jednym z elementów szacowania stanu technicznego nawierzchni lotniskowych jest ocena stopnia ich zdegradowania prowadzona w oparciu o stwierdzone uszkodzenia i przeprowadzone naprawy. Takie podejście pozwala na zaplanowanie niezbędnych zasobów potrzebnych do wykonania napraw i racjonalne zaplanowanie remontów. Wskaźnik oceny stopnia zdegradowania powierzchni badanej nawierzchni obliczany w oparciu o obmiarowane uszkodzenia i naprawy pozwala na całościową ocenę ich stanu technicznego. Podstawową informacją niezbędną do oceny stopnia zdegradowania nawierzchni jest pozyskanie danych z przeprowadzonej inwentaryzacji. W oparciu o uzyskane dane o uszkodzeniach i wykonanych naprawach analizuje się stopień zdegradowania nawierzchni lotnisk i na tej podstawie określa się kryteria ich oceny.
Multi-criteria analysis presented in the article is a method of evaluating the weighted co-normally requiring an assessment of degradation airfield pavements. Its base has in determining a number of criteria for the selection variant, taking into account different weights to each criterion. An important factor that affects the safety of the flight operations is appropriate of airport management based by obtained in system status information about the surface of the functional elements. One of the elements to estimate the technical conditio of airport pavement is to assess the degree of degradation performed based on the damage found and carriedsmoked repairs. This approach allows for planning the necessary resources needed to repair and rational planning of repairs. Indicator assessment of the degree of degradation area of the test surface is calculated based on the damage and repair as required allows for a comprehensive evaluation of their technical condition. The basic information needed to assess the degree of degradation is gaining ground data from the inventory. Based on the data of the damage and made repairs analyzed the degree of degradation and on the surfaces airport basis of defined criteria for their evaluation.

Opis:
The Histogram Test method is a popular technique in analog-to-digital converter (ADC) testing. The presence of additive noise in the test setup or in the ADC itself can potentially affect the accuracy of the test results. In this study, we demonstrate that additive noise causes a bias in the terminal based estimation of the gain but not in the estimation of the offset. The estimation error is determined analytically as a function of the sinusoidal stimulus signal amplitude and the noise standard deviation. We derive an exact but computationally difficult expression as well as a simpler closed form approximation that provides an upper bound of the bias of the terminal based gain. The estimators are validated numerically using a Monte Carlo procedure with simulated and experimental data.

The paper is devoted to a new method for assessment of the grassy airfield surface. The existing methods are based on soil related parameters such as CI (Cone Index) or CBR (California Bearing Ratio). One disadvantage of those methods is that the prediction of ground performance of an aircraft on a soft surface requires recalculation and conversion when calculating the takeoff or the landing of ground roll distances. Therefore, the authors’ idea was to introduce a method based on direct coefficients, related to the wheel performance. The knowledge of the actual values of rolling resistance and braking friction facilitates predicting the airplane ground performance in order to perform safe operations. We developed two original measuring devices, a single wheel tester and a portable surface tester. The devices are presented in this paper together with schematics and illustrations. The wheel tester was designed with the use of an airplane landing gear wheel, into which a five-element, wheel dynamometer was embedded. The measuring wheel was mounted on a trailer and the complete wheel tester was carried on a base vehicle (SUV). The second device is a portable tester, operated by a single technician. The portable tester was built with the use of a scale wheel (a model airplane landing gear wheel), which was supported on two load cells. The load cells measure surface reaction forces acting on a wheel during low speed rolling and braking. Another important parameter of a grassy surface is its roughness. It is almost impossible to maintain the grassy surface so that it is perfectly smooth. A typical grass field is a living ecosystem, which transforms its external shape and builds a rough surface. This must be monitored and for this purpose we used a commercially available LIDAR device. The LIDAR operates on a principle of light odometer and it allows 1mm resolution in short distance measurements. The paper includes the primarily results obtained in field experiments with the use of the presented devices. It can be concluded that the presented method may set fundamentals of a new system for assessment of grassy airfields. Further studies and research should focus on validation of the method and preparation for certification.

Investment activity can be consider in two options: the diagnose and prognose. The qualitative indicators of diagnose represent the macroeconomic tendencies of economic development by reason of the high part of industry in realisation of total investment. The qualitative indicators of prognose have a leading character and they inform about of the expectations of economic agents in the changes of investment, source of finance, kinds and results of investment. The credibility of investment indicators is better than the other qualitative indicators (for example demand). They can be additional instrument in formulation of medium time strategy.

Opis:
The physical and mechanical properties of rocks (i.e., compressive strength, tensile strength, workability, or compactness) are often taken into account during the selection of a mining method and type of mining machine as well as the mining tools themselves. However, one of the main reasons for the abrasive wear of mining picks is the abrasiveness of rocks, which is seldom taken into consideration because there is lack of unambiguous and proven methods for its determination. The article presents the research plan and methodology, the stand for testing the abrasivity of rocks, the course of conducting preliminary tests as well as the statistical treatment of the results using the Statistica program, and determining the final values of the input variables in the basic research. The method has been developed taking into account rock abrasivity when selecting and forecasting the wear of mining tools.

Szczególnym walorem tego instrumentarium jest możliwość łatwego rozpowszechnienia dzięki temu, że bazuje na standardowym urządzeniu, powszechnie stosowanym w skali międzynarodowej.
The developed and verified test method, which is presented in the paper, is destined for surface fatigue life investigation of concentrated, lubricated friction joints with elements made from various materials and with a surface layer created by various technologies. In order to conduct the tribological tests in accordance with the above-mentioned method, a modified four-ball tester is used. In the article, the verification test results of steel friction couples lubricated with various oils and greases are presented. The presented testing equipment makes it possible to perform low-cost, low time-consuming tests with very high repeatability of the results and can constitute an experimental base for research and development works on the preparation of new materials and lubricants. The particular advantage of the introduced test equipment is the ability to be widely spread, thanks to the fact that it is based on a testing machine that is commonly used on an international scale.

Opis:
In the article, different ways of use of the results of business tendency surveys in manufacturing industry conducted in the Central Statistical Office of Poland have been presented. The survey conducted since June 1992 has been described: its scope, frequency, content of questionnaires, sampling method, grouping of results. Long enough time-series and good quality of results prove to use this survey's results in short-term analysis of the present and future economic situation. To evaluate quality of business tendency survey's results, comparison between qualitative information and similar quantitative indices (for sold production, employment and prices) and between diagnosis and forecasts (general econoinic situation, total and foreign demand, sold production, financial situation) have been presented. Additionally comparison of results of different business tendency surveys (industry — construction — retail trade) has been analysed. Results for selected groups of industrial enterprises (small — large, different industrial activilies) have been presented as examples of possible detailed use of business tendency surveys' results. The general conclusion is that quality of results obtained in the above mentioned analysis is satisfying. Although a tendency to present more optimistic forecasts than diagnosis was observed, trends are comparable. Quick changes of the Polish economy cause that enterpreneurs present better forecasts for shorter period (one month instead of one quarter). Together with the stability of the Polish economy this horizon should be longer. Correlation between comparative qualitative and quantitalive surveys' results is good enough (and becoming better with the stabilisation of the economy). Quality of results obtained for different groups of enterprises is comparable, better for more stable industries, strongly linked with domestic rather than foreign markets.
