Opis:
The theory of hyperidentities generalizes the equational theory of universal algebras and is applicable in several fields of science, especially in computers sciences (see e.g. [2,1]). The main tool to study hyperidentities is the concept of a hypersubstitution. Hypersubstitutions of many-sorted algebras were studied in [3]. On the basis of hypersubstitutions one defines a pair of closure operators which turns out to be a conjugate pair. The theory of conjugate pairs of additive closure operators can be applied to characterize solid varieties, i.e., varieties in which every identity is satisfied as a hyperidentity (see [4]). The aim of this paper is to apply the theory of conjugate pairs of additive closure operators to many-sorted algebras.

Opis:
Quasigroups were originally described combinatorially, in terms of existence and uniqueness conditions on the solutions to certain equations. Evans introduced a universal-algebraic characterization, as algebras with three binary operations satisfying four identities. Now, quasigroups are redefined as heterogeneous algebras, satisfying just two conditions respectively known as hypercommutativity and hypercancellativity.

Opis:
Distributed Arithmetic (DA) plays an important role in designing digital signal processing modules for FPGA architectures. It allows replacing multiply-and-accumulate (MAC) operations with combinational blocks. The quality of implementations based on DA strongly depends on efficiency of methods that map combinational DA block into FPGA resources. Since modern FPGAs have heterogeneous structure, there is a need for quality algorithms to target these structures and the need for flexible architecture exploration aiding in appropriate mapping. The paper presents a modification of DA concept that allows for very efficient implementation in heterogeneous FPGA architectures.

Opis:
Export is crucial for economy. It influences the level of economic growth, balance of payment and social welfare among many others. Therefore, increase in exports often becomes one of the main objectives of governments. This raises the question of how to support export activity of the companies in order to ensure the expected increase in export. Approaches towards this problem differ significantly. The fact that this support is covered mainly from public funds raises the question of the justifiability and effectiveness of such assistance. The aim of this paper is to investigate whether to support export activity at all, and if so, how to do it effectively. To achieve the goal of the article the author analyzed both Polish and foreign literature, with special emphasis on the newest trade theories. The Author analyzes secondary data describing factors that determine export activity, describes the profile of a company becoming an exporter and investigates actual connection between the offered support and the increase in export activity.

In this paper we present the concept of a scalable job centric monitoring infrastructure. The overall performance of this distributed, layer based architecture called SLAte can be increased by installing additional servers to adapt to the demands of the monitored resources and users. Another important aspect is to offer a uniform global view on all data which are stored distributed to provide an easy access for users or visualisation tools. Additionally we discus the impact of these uniform access layer on scalability.

Opis:
The functional decomposition has found an application in many fields of modern engineering and science, such as combinational and sequential logic synthesis for VLSI systems, pattern analysis, knowledge discovery, machine learning, decision systems, data bases, data mining etc. It is perceived as one of the best logic synthesis methods for FPGAs. However, its practical usefulness for very complex systems depends on efficiency of method used in decomposition calculation. One of the most important steps in functional decomposition construction is selection of the appropriate input variable partitioning. In case of modern heterogeneous programmable structures efficiency of methods used to solve this problem becomes especially important. Since the input variable partitioning problem is an NP-hard, heuristic methods have to be used to efficiently and effectively search for optimal or near-optimal solutions. The paper presents a method for bound set selection in functional decomposition targeted FPGAs with heterogeneous structure. This heuristic algorithm delivers optimal or near optimal results and is much faster than other methods.

Opis:
A heterogeneous Bertrand duopoly game with bounded rational and adaptive players manufacturing differentiated products is subject of investigation. The main goal is to demonstrate that participation of one bounded rational player in the game suffices to destabilize the duopoly. The game is modelled with a system of two difference equations. Evolution of prices over time is obtained by iteration of a two dimensional nonlinear map. Equilibria are found and local stability properties thereof are analyzed. Complex behavior of the system is examined by means of numerical simulations. Region of stability of the Nash equilibrium is demonstrated in the plane of the speeds of adjustment. Period doubling route to chaos is presented on the bifurcation diagrams and on the largest Lyapunov characteristic exponent graph. Lyapunov time is calculated. Chaotic attractors are depicted and their fractal dimensions are computed. Sensitive dependence on initial conditions is evidenced.

Opis:
This paper presents results from the application of [Cu(TNBI)(NH3)2(H2O)] (CuTNO) to heterogeneous solid rocket propellants based on HTPB/AP, replacing RDX. A series of different compositions of solid heterogeneous rocket propellants based on HTPB and ammonium perchlorate, containing CuTNO or RDX, were prepared and investigated. The ballistic parameters of the examined propellants were determined by combustion in a laboratory rocket motor (LRM). The ballistic properties were evaluated in the pressure range 4-10 MPa and it was found that the linear burning rate at 10 MPa increased by more than 20% for the CuTNO containing propellant, compared to the RDX-based composition. By linear regression of the r = f(p) curves obtained, the burning laws for the investigated propellants were determined. It was found that the CuTNO additive increases the pressure coefficient by over 46%, compared to unmodified propellant. The determination of the sensitivities to friction and impact, the calorific value, hardness and decomposition temperature of the propellants obtained were also investigated.

Opis:
SCMNPs@Uridine/Zn is utilized as an environmental-friendly and efficient heterogeneous nanocatalyst for two one-pot four-component condensation reactions, containing hydrazine hydrate, arylaldehyde, ethyl acetoacetate, and barbituric acid to yield tricyclic fused pyrazolopyranopyrimidine derivatives (5a-q), and hydrazine hydrate, arylaldehyde, malononitrile, and dimethyl acetylenedicarboxylate/diethyl acetylenedicarboxylate to yield 3-methyl carboxylate substituted pyrano[2,3-c]pyrazole derivatives (8a-y) under solvent-free conditions with high to excellent yields. The main advantages of this process are easy work-up, short reaction times, no chromatographic purifications, and recyclability of the catalyst for a minimum of six runs without any signifcant decrease in yields of the products. Also, the prepared catalyst SCMNPs@Uridine/Zn was synthesized and fully characterized by various techniques including Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray (EDX), thermogravimetric analysis (TGA), X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and Raman spectroscopy.

Opis:
Ensuring the homogeneity of the indoor climate throughout the greenhouse is very important for uniform plant cultivation. In the study carried out to determine the indoor climate distribution in the heated greenhouse in the terrestrial climate, indoor temperature, relative humidity, dew point and vapour pressure deficit values were measured from 8 different measurement points. The distribution pattern of the measurement points was made horizontally and vertically at 2, 4 and 6 meters. Sensor placements are grouped vertically at 2 meters (G1: S1, S2 S3), at 4 meters (G2: S4, S5, S6) and at 6 meters (G3: S7, S8). Measurements taken during the day are divided into three parts. The climatic changes in the greenhouse were monitored as daily (00:00-23:30), daytime (08:30-17:30) and night (18:00-08:00) hours. According to the results obtained from the research, it was determined that the indoor climate parameters in the greenhouse change during the average daily, daytime and night hours at different times of the day and at different locations. According to this, it has been determined that it is important for better regulation of the greenhouse climate by monitoring the changes in the plant level as it rises from the greenhouse floor to the ridge with multiple sensors instead of a single sensor.

Opis:
The research, presented in this paper, concernes the controllability of a multi-agent network with a directed, unweighted, cooperative, and time-invariant communication topology. The network’s agents follow linear and heterogeneous dynamics, encompassing first-order, second-order, and third-order differential equations over continuous time. Two classes of neighbour-based linear distributed control protocols are considered: the first one utilises average feedback from relative velocities/relative accelerations, and the second one utilises feedback from absolute velocities/absolute accelerations. Under both protocols, the network’s agents achieve consensus in their states asymptotically. We observe that both of the considered dynamical rules exploit the random-walk normalised Laplacian matrix of the network’s graph. By categorising the agents of the network into leaders and followers, with leaders serving as exogenous control inputs, we analyse the controllability of followers within their state space through the influence of leaders. Specifically, matrix-rank conditions are established to evaluate the leader– follower controllability of the network under both control protocols. These matrix-rank conditions are further refined in terms of the system matrices’ eigenvalues and eigenvectors. The inference diagrams presented in this work provide deeper insights into how leader– follower interactions impact the network controllability. The efficacy of the theoretical findings is validated through numerical examples.

Opis:
The comparative experimental study has been performed of removal of pharmaceuticals such as paracetamol and ibuprofen from aqueous solution by ozonation and photochemical degradation in several types of reactors. Ozone, oxygen, and hydrogen peroxide were used as oxidizing agents. Heterogeneous photocatalysis was carried out in the presence of anatase type TiO2 catalyst. To determine the amount of radiation emitted by the UV lamps and transferred into the reactor, chemical feroxioxalate actinometric experiments were performed. The degree of the pollutant removal was monitored by HPLC, COD, BOD5, and TOC. An ecotoxic biological test of process products with Parachlorella kessleri was also evaluated. The results indicate that the removal of both pharmaceuticals is most effective by heterogeneous photocatalysis. In the UV processes, the degradation rate increased considerably when H2O2 was added. However, the addition of peroxide into the ozonation system improved the ozonation only slightly. All products of the processes tested showed improved biodegradability according to the BOD5/COD ratio and low toxicity to Parachlorella kessleri.

Opis:
Distributed arithmetic is well known technique of designing FIR filters in FPGA devices. The quality of such filter implementation strongly depends on synthesis results of the DALUT block. Heterogeneity of modern FPGA structures introduces new possibilities into implementation process, that may lead to better results, but also makes it more complicated. This paper presents the simple mathematical model for estimating the necessary FPGA resources to implement DA-LUT using decomposition-based approach. The model takes into account the type of logic cells or memory blocks used for decomposition process. The proposed model is help ful to determinate the DALUT decomposition strategy for further automation of modified distributed arithmetic decomposition method.
