Opis:
A synthesis method for designing two-dimensional lossless finite impulse response (FIR) filters for various digital signal processing tasks is proposed. The synthesis method is based on using a 2-D embedding approach to obtain the paraunitary transfer function matrix of the lossless FIR filter. The elements of the paraunitary transfer function matrix are the transfer function of a given lossy FIR structure and the transfer functions for its complementary structures. The embedding method is used to design complementary FIR filter structures for several known lossy FIR filters. The lossless FIR filter matrix obtained in this article has a size of 3 × 1 and satisfies the paraunitary conditions. The conditions are described by a set of nonlinear equations. A modified Newton method is used to solve this set of equations. The proposed design method is used to determine the lossless structures of two-dimensional FIR filters for various digital processing tasks.

Opis:
Many interconnected systems in the real world, such as power systems and chemical processes, are often composed of subsystems. A decentralized controller is suitable for an interconnected system because of its more practical and accessible implementation. We use the homotopy method to compute a decentralized controller. Since the centralized controller constitutes the starting point for the method, its existence becomes very important. This paper introduces a non-singular matrix and a design parameter to generate a centralized controller. If the initial centralized controller fails, we can change the value of the design parameter to generate a new centralized controller. A sufficient condition for a decentralized controller is given as a bilinear matrix inequality with three matrix variables: a controller gain matrix and a pair of other matrix variables. Finally, we present numerical examples to validate the proposed decentralized controller design method.

The aim of this work was to determine the effectiveness of using the FMEA method in the traditional and modern versions for a small company producing plastic toys. It also identified the production process of a plastic instrument toy selected for analysis by dividing operations into adding and not adding value, in accordance with the Lean concept. Through the FMEA sheets constructed and presented in this work in both versions of this method, the causes and effects of defects in the technological operations of the production process of the test subject were presented. A risk analysis was carried out using assessments available for the traditional and new versions, and preventive and detective actions were proposed. The result of the work was a comparison of risk indicators characteristic for both versions of the FMEA method and an assessment of the effectiveness of this method in the analysed enterprise. Emphasis was placed on the human factor in the research. Both the division of operations into adding and not adding value, as well as the FMEA method, were useful for further optimization and process improvement activities.

The aim of the paper is to analyse acoustic reflective muffler applying the scattering matrix method. In general, the method is based on dividing the muffler/system into separate subsystems and apply the acoustic multi-ports theory to calculate the scattering matrix of each element to finally combine the results and obtain the scattering matrix of the entire system/muffler. The multi-port procedure is derived from the theory of electric networks and allows to analyse acoustic devises of complex geometry with prescribed accuracy. Based on the scattering matrix, the transmission loss was determined.

Opis:
Applied element method (AEM) is a recently displacement-based structural analysis method. It provides the benefits of both the finite element method (FEM) and the discrete element method (DEM). This method relies on those structures are segmented into rigid elements linked by normal and shear springs. In this paper a brief note of the AEM is given. Then, using the AEM, a 2D MATLAB open source program was created to analyze different structures with varied boundary conditions and to permit researchers for enhancing the method. The proposed program was verified using linear elastic analysis and large deformation static analysis. The influence of element size and the number of connecting springs between elements was studied. Finally, the proposed program was capable of tracking failed elements and their spread. In addition, the program could predict deflection values and structure deformed shape.

Opis:
The paper concerns the dimensional analysis of simple acoustic metamaterials and its experimental verification in a computer model. Due to their decreased thickness possible because of the thermoviscous losses and sound dispersion that occur in acoustic metamaterials, such structures are gaining popularity, both as sound absorbers and diffusers. This implies the need to find their equivalents to be used at scale - both for modeling interiors with metamaterials and developing more complicated structures. The paper discusses the dimensional analysis performed for a generalized unit cell of a metamaterial with a resonator. The dimensional analysis shows the need for scaling both the geometrical dimensions of the structure and the parameters of the medium - air. The dimensional analysis was derived based on the transfer matrix method and was proven correct with the finite element method model. The paper also discusses the consequences of neglecting the air criteria, which are impossible to be fulfilled. This opens the question of finding new criterial numbers allowing the correct reflection of acoustic metamaterials at scale.

Opis:
The paper presents the research on the influence of airflow resistance on the sound absorption coefficient of layered porous structures. For the calculation of the sound absorption coefficient, the models of layered sound-absorbing structures were developed with the use of numerical computational models. Using the developed models, optimization was carried out to maximize the average sound absorption coefficient of the structures for a given frequency range. As a result of the research, the dependence of the change in airflow resistance for the successive layers of the material was determined. The results of the work will be particularly useful in the design of wedges used in anechoic chambers.

Artykuł przedstawia uogólnione podejście dla dobrze znanej metody najmniejszych kwadratów stosowanej w praktyce metrologicznej. Wyznaczone niepewności punktów pomiarowych i korelacje między mierzonymi zmiennymi tworzą symetryczną macierz kowariancji, której odwrotność mnożona jest lewostronnie i prawostronnie przez wektory błędów obu zmiennych losowych i stanowi funkcję kryterialną celu. Aby uzyskać maksymalną wartość funkcji największej wiarygodności i rozwiązać złożony problemu minimalizacji funkcji kryterialnej, zaprezentowano oryginalny sposób wyznaczenia funkcji kryterialnej do postaci jednoargumentowej zależności obliczanej numerycznie, w której jedyną zmienną jest poszukiwany współczynnik kierunkowy prostej regresji. Artykuł zawiera podstawowe informacje o tego typu regresji liniowej, dla której najlepiej dopasowana prosta minimalizuje funkcję celu. Na przykładzie obliczeniowym pokazana jest pełna procedura dopasowania numerycznego prostej do danego zestawu punktów pomiarowych o zadanych niepewnościach i współczynnikach korelacji tworzących macierz kowariancji.
The paper presents a generalized approach for the well-known least squares method used in metrological practice. In order to solve the complex problem of minimizing the objective function to obtain the maximum value of the likelihood function, the original way of determining this function in the form of a unary relationship calculated numerically was presented. The article presents borderline cases with analytical solutions. The computational example shows the full procedure of numerical adjustment of a straight line to a given set of measurement points with given uncertainties and correlation coefficients forming the covariance matrix.

Opis:
Occupational risk is closely related to work environment. For the same positions, but in different working conditions threats and level of risk can be different. For this also estimating the degree of damage hazard the largest possible should be adopted effects. However, when estimating probability occurrence of threats should include, among others: working conditions, events from the past, or possible employee behavior (in particular those that may be the cause of an accident at work). The source of the above information may be data from statistics or observations of work stations. The article presents the assessment of occupational risk at the position of the laser cutter operator, which was carried out using the Job Safety Analysis (JSA) method. According to this method, occupational risk is determined on the basis of two parameters, i.e.: consequences of C and probability of consequences P. In turn, the probability of consequences is the sum of three factors: frequency of hazard F, probability of event O and avoidability or damage limitation A.

Opis:
The aim of the paper is to experimentally determine the scattering matrix S of an example reflective muffler of cylindrical geometry for Helmholtz number exceeding the plane wave propagation. Determining the scattering matrix of an acoustic systems is a new and increasingly used approach in the assessment of reduction of noise propagating inside duct-like elements of heating, ventilation and air conditioning systems (HVAC). The scattering matrix of an acoustic system provides all necessary information on the propagation of wave through it. In case of the analysed reflective silencer, considered as a two-port system, the noise reduction was determined by calculating the transmission loss parameter (TL) based on the scattering matrix (S). Measurements were carried out in two planes of the cross-section of pipes connected to the muffler. The paper presents results of the scattering matrix evaluation for the wave composed of the plane wave (mode (0,0)) and the first radial mode (0,1), each of which was generated separately using the self-designed and constructed single-mode generator. The gain of proceeding measurements for single modes stems from the fact that theoretically, calculation of the S-matrix does not require, as will be presented in the paper, calculation of the measurement data inverse matrix. Moreover, if single mode sound fields are well determined, it ensures error minimization. The presented measurement results refer to an example of a duct like system with a reflective muffler for which the scattering matrix S was determined. The acoustic phenomena inside such a system can be scaled by the parameter ka.

In the article the method of analysis of financial potential using taxonomy method has been developed as well as it has been tested on the basis of empirical data of Ukrainian forestry enterprises. The application of such a method made it possible to construct a rating assessment of a complex and multifactorial economic object – the financial potential, using algorithms of systematization to multidimensional quantities. The authors present the stages of application of analytical procedures for assessing the dynamics of taxonomic indicators of financial potential as well as for constructing the rating of the suggested business entities. An innovative model of financial potential of forestry enterprises is proposed, which will allow to identify the complex of properties of an object as a basis for forming a set of analytical procedures for assessing its state. The obtained results of the analysis can serve as the basis for constructing a management strategy to optimize the financial potential of the enterprise.

So far, numerous studies have been published on the selection of appropriate maintenance tactics based on some factors affecting them such as time, cost, and risk. This paper aims to develop the TRIZ contradiction matrix by explaining the dimensions and components of each of the following Reactive maintenance tactics. The related findings of previous studies were analyzed by adopting “Rousseau and Sandoski” seven-step method to identify and extract the relationships between TRIZ principles and Reactive maintenance tactics. Thereafter, 5 Reactive maintenance tactics were replaced TRIZ’s 40 principles in the TRIZ contradiction matrix. Finally, the ANP method were used to extract and prioritize the appropriate Reactive maintenance tactics. The proposed matrix in this research was used in the desalination section of one of the oil companies to select on the appropriate Reactive maintenance tactics. The results of this research is useful for managers and maintenance specialists of units in making decisions to provide appropriate Reactive maintenance tactics for the desired equipment.

Mając na uwadze doświadczenia z realizacji inwestycji kolejowych w Polsce w poprzednich latach, można stwierdzić, iż ich przebieg jest obciążony wieloma specyficznymi czynnikami losowymi. Aby zminimalizować wystąpienie nieprzewidzianych, losowych, zagrożeń podczas przyszłych realizacji tych inwestycji, autorzy opracowali prostą w zastosowaniu metodę Railway Matrix of Risk Factors (RMRF) specjalnie dedykowaną do planowania inwestycji kolejowych. Prognozowanie realnych terminów oraz kosztów zakończenia inwestycji zostało oparte w niej na wiarygodnej bazie danych w zakresie konkretnych czynników ryzyka. Opracowanie metody było poprzedzone wieloma badaniami z udziałem licznych ekspertów nad identyfikacją oraz kwantyfikacją czynników ryzyka oraz weryfikacją w rzeczywistym procesie inwestycyjnym.
Considering the experiences from railway investment projects implementation in Poland in previous years, it can be concluded that they are burdened with numerous specific random factors. To minimise the occurrence of unforeseen, random risks during the future implementation of such investment projects, the authors have developed a simple Railway Matrix of Risk Factors (RMRF) specially dedicated for planning railway investment projects. Forecasting actual completion dates and costs for the investment project has been based on a reliable database for specific risk factors. The method's development has been preceded by numerous studies together with numerous experts in identification and quantification of risk factors and verification in an actual investment project process.

Over the years, the generally accepted fact is that the Sarrus’s rule which was developed by a French Mathematician, P. F. Sarrus in 1833, is only limited to finding the determinant of 3 × 3 Matrices. However, in my previous work [1] “On the Extension of Sarrus’ Rule to n × n (n > 3) Matrices: Development of New Method for the Computation of the Determinant of 4 × 4 Matrices” which was published in International Journal of Engineering Mathematics, vol. 2016, 14 pages, the possibility of extending the Sarrus’s rule to find the determinant of 4 × 4 matrices was displayed using the newly established Gbemi’s method. The simplicity, accuracy, ease of applications as well as comparatively low computational time and cost of the proposed Gbemi’s method were pointed out. In this further study, additional nine methods of extending the Sarrus’s rule to evaluate the determinant of 4 × 4 matrices are established. The further establishes the effectiveness, consistency for handy calculations, high accuracy and relatively low computational time of the new method. Therefore, with the aid of the generalized extended method to n × n, it could be stated that method will greatly reduce the computational and running time of most software that are largely based on matrices. Consequently, this will greatly reduce the computational cost.
