Opis:
Babenyshev and Martins proved that two hidden multi-sorted deductive systems are deductively equivalent if and only if there exists an isomorphism between their corresponding lattices of theories that commutes with substitutions. We show that the π-institutions corresponding to the hidden multi-sorted deductive systems studied by Babenyshev and Martins satisfy the multi-term condition of Gil-F´erez. This provides a proof of the result of Babenyshev and Martins by appealing to the general result of Gil-F´erez pertaining to arbitrary multi-term π-institutions. The approach places hidden multi-sorted deductive systems in a more general framework and bypasses the laborious reuse of well-known proof techniques from traditional abstract algebraic logic by using “off the shelf” tools.

Opis:
This paper aims to present a new equivalent scheme of multi-windings traction transformers, based on multiport purely inductive circuit. The mathematical background of this equivalent scheme is described. The determination of the different scheme elements is made through a finite-elements calculation of both main and leakage inductances, for the case of a four-winding transformer. A procedure is defined, which allows to estimate the values of these elements from some measurements on the transformer at no-load and short-circuit operations. A specific strategy of short-circuit tests is described, allowing to determine all parameters in a rather simple way.

The offshore structures, such as multi-articulated towers, manipulators working in waving fluid are more and more popular structures. Commonly they are modelled as an inverted pendulum. The motion of such tower immersed in waving fluid is under consideration. It is assumed that the tower is hinged to the seabed by the hinge with friction. The joint of tower elements is the hinge with friction, as well. Motion of tower loaded by regular wave fluid force is considered. The numerical experiment shows that the multi-potential systems may move chaotically for some parameters of the tower and the fluid.

Opis:
By the green point of view, supply chain management (SCM), which contains supplier and location selection, production, distribution, and inventory decisions, is an important subject being examined in recent years by both practitioners and academicians. In this paper, the closed-loop supply chain (CLSC) network that can be mutually agreed by meeting at the level of common satisfaction of conflicting objectives is designed. We construct a multi-objective mixed-integer linear programming (MOMILP) model that allows decision-makers to more effectively manage firms’ closed-loop green supply chain (SC). An ecological perspective is brought by carrying out the recycling, remanufacturing and destruction to SCM in our proposed model. Maximize the rating of the regions in which they are located, minimize total cost and carbon footprint are considered as the objectives of the model. By constructing our model, the focus of customer satisfaction is met, as well as the production, location of facilities and order allocation are decided, and we also carry out the inventory control of warehouses. In our multi-product multi-component multi-time-period model, the solution is obtained with a fuzzy approach by using the min operator of Zimmermann. To illustrate the model, we provide a practical case study, and an optimal result containing a preferable level of satisfaction to the decision-maker is obtained.

Opis:
The multi-chambered gun concept is based on the effect of increasing muzzle velocity of weapon system without need of new technologies or excessive dimensions. The mathematical model of interior ballistics of the multi-chambered gun was assembled by means of extension and modification of the thermodynamic model of interior ballistics of conventional gun. The reliability of numerical solution of a model has been examined in the comparison with results of ballistic shootings with several arrangements of the experimental weapon system. Subsequently the numerical sensitivity analysis of the interior ballistics model has been carried out as well as the simplified system of analytical approximate expressions comprising the crucial gun design characteristics has been built up. Outputs of both the sensitivity analysis and simplified system could be used in the case of multi-chambered gun designing in order to reach maximum velocity with no simultaneous rise in maximal ballistic pressure.

Opis:
Niching is a group of techniques used in evolutionary algorithms, useful in several types of problems, including multimodal or nonstationary optimization. This paper investigates the applicability of these methods to evolutionary multi-agent systems (EMAS), a hybrid model combining the advantages of evolutionary algorithms and multi-agent systems. This could increase the efficiency of this type of algorithms and allow to apply them to a wider class of problems. As a starting point, a simple but flexible EMAS framework is proposed. Then, it is shown how to extend this framework in order to introduce niching, by adapting two classical niching methods. Finally, preliminary experimental results show the efficiency and the simultaneous discovery of multiple optima by this modified EMAS.

Opis:
In this paper, we propose a multi-operator differentia evolution variant that incorporates three diverse mutation strategies in MOEA/D. Instead of exploiting the local region, the proposed approach continues to search for optimal solutions in the entire objective space. It explicitly maintains diversity of the population by relying on the benefit of clustering. To promowe convergence, the solutions close to the ideal position, in the objective space are given preference in the evolutionary process. The core idea is to ensure diversity of the population by applying multiple mutation schemes and a faster convergence rate, giving preference to solutions based on their proximity to the ideal position in the MOEA/D paradigm. The performance of the proposed algorithm is evaluated by two popular test suites. The experimental results demonstrate that the proposed approach outperforms other MOEA/D algorithms.

Opis:
Super-resolution image reconstruction utilizes two algorithms, where one is for single-frame image reconstruction, and the other is for multi-frame image reconstruction. Singleframe image reconstruction generally takes the first degradation and is followed by reconstruction, which essentially creates a problem of insufficient characterization. Multi-frame images provide additional information for image reconstruction relative to single frame images due to the slight differences between sequential frames. However, the existing super-resolution algorithm for multi-frame images do not take advantage of this key factor, either because of loose structure and complexity, or because the individual frames are restored poorly. This paper proposes a new SR reconstruction algorithm for images using Multi-grained Cascade Forest. Multi-frame image reconstruction is processed sequentially. Firstly, the image registration algorithm uses a convolutional neural network to register low-resolution image sequences, and then the images are reconstructed after registration by the Multi-grained Cascade Forest reconstruction algorithm. Finally, the reconstructed images are fused. The optimal algorithm is selected for each step to get the most out of the details and tightly connect the internal logic of each sequential step. This novel approach proposed in this paper, in which the depth of the cascade forest is procedurally generated for recovered images, rather than being a constant. After training each layer, the recovered image is automatically evaluated, and new layers are constructed for training until an optimal restored image is obtained. Experiments show that this method improves the quality of image reconstruction while preserving the details of the image.

Multiple core processors have already became the dominant design for general purpose CPUs. Incarnations of this technology are present in solutions dedicated to such areas like computer graphics, signal processing and also computer networking. Since the key functionality of network core components is fast package servicing, multicore technology, due to multi tasking ability, seems useful to support packet processing. Dedicated network processors characterize very good performance but at the same time high cost. General purpose CPUs achieve incredible performance, thanks to task distribution along several available cores and relatively low cost. The idea, analyzed in this paper, is to use general purpose CPU to provide network core functionality. For this purpose parameterized system model has been created, which represents general core networking needs. This model analyze system parameters influence on system performance.

Introduction. Tuberculosis is one of the oldest infections known to mankind. Of all infectious diseases, tuberculosis causes the most fatalities of any infection. The incidence of tuberculosis on the rise due to the increased prevalence of HIV infection. The incidence of drug resistance strains of mycobacterium is also on the rise. When the mycobacterium is resistant to both INH and rifampicin it is called multi drug resistant tuberculosis. There is a primary and an acquired type of drug resistance. Multidrug resistant tuberculosis is a not only a problem for the patient but also for society at large. The treatment of multidrug resistant tuberculosis requires an entirely different approach. Aim. In this review, we are going to describe the etiopathogenesis, diagnosis, investigations and treatment of multi drug resistant tuberculosis. Material and methods. Analysis of the current literature. Results. Genetic factors, previous treatment, and other factors predisposes the onset of drug resistance. By early detection and prevention of spread of drug resistant strains we can prevent the spread of resistant strains. Conclusion. Drug resistance in tuberculosis is a very complex and dangerous problem. We have to prevent the development and spread of MDRTB. Good quality drugs should be used and made available to all sections of the population. Enhancing the National tuberculosis programs is the best way to attain an effective way to control this menace.

Opis:
Iron ore blending in an open-pit mine is an important means to ensure ore grade balance and resource recycling in iron mine industrial production. With the comprehensive recovery and utilisation of resource mining, the multi-source and multi-target ore blending method has become one of the focuses of the mining industry. Scientific and reasonable ore blending can effectively reduce the transportation cost of the enterprise. It can also ensure that the ore grade, washability index and iron carbonate content meet the requirements of the concentrator and significantly improve the comprehensive utilisation rate and economic benefits of the ore. An ore blending method for open-pit iron ore is proposed in this paper. The blending method is realised by establishing the ore blending model. This model aims to achieve maximum ore output and the shortest transportation distance, ore washability index, total iron grade, ferrous iron grade and iron carbonate content after the ore blending meets the requirements. This method can meet the situation of a single mine to a single concentrator and that of a single mine to multiple concentrators. According to the results of ore blending, we can know the bottleneck of current production. Through targeted optimisation management, we can tap the production potential of an open-pit mine.

Opis:
The paper addresses the problem of analysing information tables which contain objects described by both attributes and criteria, i.e. attributes with preference-ordered scales. The objects contained in those tables, representing exemplary decisions made by a decision maker or a domain expert, are usually classified into one of several classes that are also often preference-ordered. Analysis of such data using the classic rough set methodology may produce improper results, as the original rough set approach is not able to discover inconsistencies originating from consideration of typical criteria, like e.g. product quality, market share or debt ratio. The paper presents the framework for the analysis of both attributes and criteria and a very promising algorithm for generating reducts. The algorithm presented is evaluated in an experiment with real-life data sets and its results are compared to those by two other reduct generating algorithms.

Opis:
Celem artykułu jest zaprezentowanie, w jaki sposób koncepcja multi-level governance została dostosowana do specyfiki niemieckiego samorządu gminnego oraz na czym polega jej istota. Autorka doszła do dwóch ustaleń. Po pierwsze, powstanie multi-level governance w Niemczech oparte jest na działaniach odgórnych i następuje od kraju związkowego do gmin (top-down). Tworzenie układu sieciowego wynika wówczas z przekonania władz państwowych o efektywniejszej realizacji zadań publicznych opartej na współpracy z podmiotami prywatnymi, których działania moderowane są przez podmioty władcze. Po drugie, wprowadzenie multi-level governance na poziomie lokalnym poprzedzone jest regional governance na szczeblu krajów związkowych stanowiącą dostosowanie koncepcji governance do specyfiki państwa federalnego. Najważniejszym jednak wnioskiem płynącym z artykułu jest ten, że multi-level governance zostało wprowadzono w strukturę samorządu gminnego za pośrednictwem specjalnego typu zadań publicznych (Gemeinschaftsaufgaben).
The aim of this article is to present how the concept of multi-level governance was adopted to the German local government. The author made two arrangements. Firstly, the emergence of multi-level governance in Germany is based on top-down activities, which occur between federal states and communities. Creating network systems results from the conviction of the state authorities about fulfillment of public tasks, which is more effective with private organizations, which are moderated by public entities. Secondly, before implementing multi-level governance on local level, the regional governance was posed on the level of federal states, which is the adjustment of governance’s concept to the specify of federal states. Notwithstanding, the most important result from this article is the fact, that multi-level governance was implemented to the structure of local government in the characteristic type of public task (Gemeinschaftsaufgaben).

To undergo this problem multi-input multi-output fuzzy logic controller (MIMO-FLC) affect on propelled traction system forming MMS process was proposed. This paper introduces a MIMO-FLC applied on speeds of electric vehicle, the electric drive consists of two directing wheels and two rear propulsion wheels equipped with two light weight induction motors. The EV is powered by two motors of 37 kilowatts each one, delivering a 476 Nm total torque. Its high torque (476Nm) is instantly available to ensure responsive acceleration performance in built-up areas. Acceleration and steering are ensured by an electronic differential system which maintains robust control for all cases of vehicle behavior on the road. It also allows controlling independently every driving wheel to turn at different speeds in any curve. Direct torque control based on space vector modulation (DTC-SVM) is proposed to achieve the tow rear driving wheel control. The MIMO-FLC control technique is simulated in MATLAB SIMULINK environment. The simulation results have proved that the MIMO-FLC method decreases the transient oscillations and assure efficiency comportment in all type of road constraints, straight, slope, descent and curved road compared to the single input single output fuzzy controller (SISO-FLC).

Opis:
Europarties are regarded as multi-level organizations, like parties operating in federal or devolved states. Examined is whether they can even be treated as political parties sensu stricto and whether the concepts used to test the relations between the national and regional party structures (vertical integration, influence) could be used to study relationships between the national and European structures. It was indicated that Europarties can be considered both as the additional arenas of national parties’ activity and independent political actors consisted of national parties (multi-level parties). The second perspective was used to research 13 existing Europarties. In result, the similarities between the PES and PEL, but differences between the EPP and PES in term of vertical integration and influence were shown. Hence, in the article was proven that there is no one model of relations between the national and European party structures and the parties differ from each other as far as their internal structures are concerned.

Opis:
Ethnic conflicts were the main forms of political instability in the multi ethnic societies during second half of twenty century and beginning of new century. The goal of this study determinates social context of ethnic conflict in multi ethnic societies. The methodology was comparative study. Data gathering by documents and secondary data. Data and documents show that Ethnic differences' and discrimination were the main cause of ethnic violence. The results indicated that much country in the world encounter with ethnic conflict during decades. But incidence of ethnic violence was different in varying country. In developing country incidence were low and in the developing sever. Developing country management ethnic conflict by participation and justice policy that the equality is the best way for resolve this problem.

OHS
Opis:
The supervision of OHS conditions (working conditions and the realization of work tasks) is one of the basic obligations of the employer. The number and variety of describing elements (and thus being subject to assessment) means that synthetic measures (measures that are one-dimensional images of complex phenomena) are more and more frequently applied to solve problems of that type. Although the methods of multivariate statistics used for this purpose differ in the way they treat assessment criteria (defining mutual dependency thresholds, unifying the field of compared criteria), the final effect of their application always offers the option to replace the entire set of features describing a given object with one variable (aggregate). The article presents a potential applicability of one of the so-called discrete multi-criteria decision-making methods (Simple Additive Weighting), which allows to determine a linear combination of normalized elements of the decision matrix and the elements of weight vector. As part of the article, the working conditions at 5 workstations were assessed (a miner’s workstation in 5 underground mine workings being excavated), taking into account 8 assessment criteria (6 were cost criteria and 2 – criteria of qualitative character). In effect of the application of the Simple Additive Weighting method, we could determine the ranking vector R, which allowed to order the examined objects and to carry out a comprehensive assessment of OSH conditions occurring in them.

Opis:
In this paper, we approach the Airport Gate Assignment Problem by Multi-objective Optimization as well as Evolutionary Multi-objective Optimization. We solve a bi-criteria formulation of this problem by the commercial mixed-integer programming solver CPLEX and a dedicated Evolutionary Multi-objective Optimization algorithm. To deal with multiple objectives, we apply a methodology that we developed earlier to capture decision-maker preferences in multi-objective environments. We present the results of numerical tests for these two approaches.

Opis:
Multi-hop ad hoc networks are promising candidates for next generation mobile communications. They have sufficient channel capacity to achieve high data rate transmission for large number of users. One advantage of multi-hop networks is to realize multi-route transmissions. Since information bit streams can be transmitted over multiple routes, we can obtain route diversity effect. In order to enhance the route diversity effect, we usually introduce forward error correction schemes. Turbo coding is one of suitable coding methods for multi-hop networks. The turbo encoder generates one message stream and two parity streams whilst the message stream is more important than the parity streams for achieving reliable communications. Thus an unequal power allocation to the message and parity streams could be effective in improving the performance. In this paper, the effect of unequal power allocation for turbo coded multi-hop networks is investigated. Assuming the channel as additive white Gaussian and binary symmetric, we will show considerable performance improvement by unequal power allocation in terms of the bit error rate performance in multi-route multi-hop networks.
