Abstract

Make-To-Stock (MTS) and Make-To-Order (MTO) are the two traditional strategies in

production management. In the case of the MTS there is a growing demand for a new

approach, which is called Make-To-Availability (MTA) strategy. The paper characterizes and

compares the MTS and MTA strategies. The comparative analysis based, among others, on

computational experiments carried out in a computer program developed in Microsoft Visual

Studio 2017 Environment was presented. The models have been prepared for both strategies

with the same assumptions: external conditions (market demand) and internal conditions

(structure of the production process). The investigation of how the strategies respond to

various scenarios of demand intensity was done. The simulation models were prepared and

validated for the case of the production line in one of the industrial automation company.

The research shows that the use of the MTA strategy in the majority of cases gives much

better results than the use of the MTS strategy due to the minimization of storage costs and

the costs of non-fulfillment of the customers’ demand. The directions for further research

were also presented.

Abstract

The model concept, as presented in this paper, is an original solution created by the author, and can be used as a proposal to build an innovative mechanism to increase the effectiveness of programming and implementation of the development policy, and improve the quality of functioning of a building research institute. The development management system included in this model is a set of actions targeting at the effective use of human and tangible resources, undertaken in a coordinated manner and leading to the achievement of previously established objectives. The market activity of building research institutes is directly or indirectly involved in construction projects, which translates into market mechanisms, such as innovation and competitiveness. In addition, it indicates the participation of a building research institute in the engineering of construction projects as a key to entrepreneurship and implementations.

Abstract

The relevance of the study is explained by the growing popularity of a political Internet, thanks to which all politicians, regardless of age and status, are able to address an audience directly without resorting to intermediaries such as the media. Taking into account the main goal of political communication – the manipulation of public consciousness, it seems especially relevant to find out what persuasive strategies politicians use to manipulate public opinion and convince their audiences of the correctness of their judgments as made opportune by the political Internet. Thus, in the present study, an attempt has been made to answer the question as to whether there are differences in the strategies and tactics of persuasion used in the personal blogs of two generations of politicians. Using the methods of computer linguistics, analyzed were ten personal blogs of politicians of different age. The study found that both young and more experienced politicians with varying degrees of intensity resort to employing all the analyzed strategies and persuasion tactics. The most popular tactics found in the blogs of the younger generation of politicians were call‑for‑action tactics, and in the blogs of their older colleagues – the tactics of incrimination.

Abstract

What is focused on in the undertaken study are teachers from schools educating in the Polish language in the Czech Republic. The author refers to the studies conducted in 2014–2016 and in 2017 among teachers from schools for the Polish national minority located in Zaolzie. These schools effectively compete with schools for the Czech majority. Among other things, they have survived owing to teachers and their decisive strategies, which involve not only strictly competitive but also various forms of collaborative behaviour.

Abstract

The present paper aims at investigating the problem of translating interjections from English into Polish. William Shakespeare’s Hamlet and its Polish translations by J. Paszkowski (1961), M. Słomczyński (1978), and S. Barańczak (1990) are chosen as the corpus for the present study. The analysis of the translations of the original English interjections will reveal the translational strategies followed by the translators. The first part of the paper is devoted to a short discussion concerning the definition and taxonomy of interjections. Next, the problem of the role interjections play in drama is discussed on the basis of the specialist literature. Finally, different translation strategies are presented followed by the analysis of the corpus material.

Abstract

The purpose of the paper is to present the author’s reflections on the origin and popularity

of various approaches to maintenance and improvement of production processes, their

terminological consistency, understanding, and practical application of their principles. The

author’s reflections are based on his observations made over his many years of activity as

a lecturer and consultant in the area of production engineering and management. It was

shown that there is a need to make scientists and practitioners aware of the relatively large

degree of freedom in defining the scope and way of application of strategies of continuous

improvement. The author’s proposal is to refer to all approaches to maintenance and improvement

of production processes with the title “Strategies of Efficient Action” and all

supporting methods as “Practices of Efficient Action”.

Considerations presented in the paper can be useful in more and more efficiently applying

the power of TQM, Six Sigma, Lean Manufacturing and other strategies of processes

maintenance and improvement in the daily activities of companies.

Abstract

The article discusses selected issues related to the process of creating a document, Strategy Warsaw 2030, adopted in May 2018. The construction of the strategy lasted almost two years and was characterized by high social involvement. The experience that Warsaw can share with other cities and municipalities clearly shows that creating documents in a participatory manner is the most possible and gives many opportunities to create synergies. At the same time, the scope of changes that the document specifi es in the context of its implementation, orders careful observation of the actions of the city authorities in the future. The article focuses primarily on the following issues: the period in which the strategy should be updated, the city’s relations with its surroundings, the strategic team, socialization and fi nally the implementation of the strategy.

Abstract

This article presents methods and algorithms for the computation of isogenies of degree ℓn. Some of these methods are obtained using recurrence equations and generating functions. A standard multiplication based algorithm for computation of isogeny of degree ℓn has time complexity equal to O(n2 M (n log n)), where M(N) denotes the cost of integers of size N multiplication. The memory complexity of this algorithm is equal to O (n log (n log (n))). In this article are presented algorithms for:

  • determination of optimal strategy for computation of degree ℓn isogeny,
  • determination of cost of optimal strategy of computation of ℓn isogeny using solutions of recurrence equations,
  • determination of cost of optimal strategy of computation of ℓn isogeny using recurrence equations,

where optimality in this context means that, for the given parameters, no other strategy exists that requires fewer operations for computation of isogeny.

Also this article presents a method using generating functions for obtaining the solutions of sequences (um) and (cm) where cm denotes the cost of computations of isogeny of degree ℓum for given costs p; q of ℓ-isogeny computation and ℓ-isogeny evaluation. These solutions are also used in the construction of the algorithms presented in this article.

Abstract

In colonies situated at the southern coast of King George Island the nesting areas of penguins of the genus Pygoscelis were investigated with respect to the protection of eggs and chicks against flooding. Relationships between the nesting strategy determined by the characteristics of breeding grounds, degree of colonization and breeding time, and the climatic conditions of zones in which majorities of particular species populations breed were presented. It was recorded, that interspecific differences in nesting strategy of pygoscelid penguins enable species which breed sympatrically to avoid competition for the nest-sites, and also seem to be responsible for various population dynamics of species in the maritime Antarctic.

Abstract

The article is devoted to the analysis of the lyrical poetry of Evdokiya Rostopchina, who was considered in the late 1830s – early 1840s as one of the most talented Russian poets. The main object of investigation is her strategy of self-representation. It is shown how Rostopchina builds her individual myth: the poetess treats herself as the heiress, the successor to Pushkin and Lermontov; she creates this myth, relying on the facts of her biography. She creates her own version of the romantic myth about the poet, varying the motives of the lyrics of these authors, as well as of Baratynsky’s poems. In the 1850s, trying to resist the realistic tendencies of the new era, she presents herself as the guardian of a high literary tradition and enters into a conscious confl ict with time, making literary “archaism” her own principle. If earlier she cultivated elegiac poetics, now she turns to satire.

Abstract

Semiochemicals are defined as informative molecules mainly used in plant-insect or insect-insect interactions as alternative or complementary components to insecticide approaches in different integrated pest management strategies. They are used to manipulate insect behaviour by affecting the survival and/or reproduction of insect pests for controlling their infestations on crops. The present review provides a basic summary of the utilization of semiochemicals for controlling insect pests. Two main topics were explored in this study. The first topic focuses on a description of semiochemicals and their types (pheromones and allelochemicals). Pheromones represent an intraspecific communication amidst members of the same species. Allelochemicals, produced by individuals of one species, modify the behavior of individuals of a different species (i.e. an interspecific effect). Allelochemicals include different informative molecules such as: allomones, kairomones, synomones, antimones and apneumones. The second topic focuses on the application of semiochemicals in IPM programs. Different semiochemicals are included in integrated pest management programs in various ways such as monitoring, mass trapping, attract-and-kill, push-pull, and disruption strategies. Pheromones are promising and can be used singly or in integration with other control strategies for monitoring and controlling insect pests in agricultural systems. For example, sex pheromones have been applied in mass trapping, disruption and attract-and-kill tactics in IPM programs.

Abstract

Novel method of space-vector-based pulsewidth modulation (PWM) has been disseminated for synchronous control of four inverters feeding six-phase drive based on asymmetrical induction motor which has two sets of windings spatially shifted by 30 electrical degrees. Basic schemes of synchronized PWM, applied for control of four separate voltage source inverters, allow both continuous phase voltages synchronization in the system and required power sharing between DC-sources. Simulations show a behavior of six-phase system with continuous and discontinuous versions of synchronized PWM.

Abstract

A large amount of electric vehicles (EVs) charging load will bring significant impact to the power system. An appropriate resource allocation strategy is required for securing the power system safety and satisfying EVs charging demand. This paper proposed a power coordination allocation strategy of EVs’ in distribution systems. The strategy divides the allocation into two stages. The first stage is based on scores assigned to EVs through an entropy method, whereas the second stage allocates energy according to EV’s state of charge. The charging power is delivered in order to maximize EV users’ satisfaction and fairness without violation of grid constraints. Simulation on a typical power-limited residential distribution network proves the effectiveness of the strategy. The analysis re- sults indicate that compared with traditional methods, EVs, which have higher charging requirement and shorter available time will get more energy delivered than others. The root- mean-square-error (RMSE) and standard-deviation (SD) results prove the effectiveness of the methodology for improving the balance of power delivery.

Abstract

This paper presents a concept of an NxM Matrix Converter (MC) modeling under periodic control strategy patented in Poland. This strategy allows to change an Nphase input system of voltages and current with the frequency fi to the M-phase output system with the frequency fo, maintaining both systems symmetrical and providing small distortions of voltage and current waveforms at rather high frequencies. In this paper the control strategy is extended for dynamic states when one of the frequencies is changed. Matrix converter equations have been derived using the constrain matrix, which is determined by the switch states. The equations have the hybrid form of a multi-port circuit. To simplify these equations the symmetrical components of input and output voltages and currents have been applied. As a result, rather simple equations have been found. They can be interpreted to an equivalent scheme. All considerations are illustrated using an exemplary 6H3 matrix converter.

Abstract

Commonly, the Park model is used to calculate transients or steady-state operations of synchronous machines. The expanded Park theory derives the Park equations from the phase-domain model of the synchronous machine by the use of transformations. Thereby, several hypothesis are made, which are under investigation in this article in respect to the main inductances of two different types of synchronous machines. It is shown, that the derivation of the Park equations from the phase-domain model does not lead to constant inductances, as it is usually assumed for these equations. Nevertheless the Park model is the most common analytic model of synchronous machines. Therefore, in the second part of this article a method using the evolution strategy is shown to obtain the parameters of the Park model.

Abstract

Based on mathematical modelling and numerical simulations, a control strategy for a Molten Carbonate Fuel Cell Hybrid System (MCFC-HS) is presented. Adequate maps of performances with three independent parameters are shown. The independent parameters are as follows: stack current, fuel mass flow and compressor outlet pressure. Those parameters can be controlled by external load, fuel valve and turbine-compressor shaft speed, respectively. The control system is purposed to meet many constraints: e.g. stack temperature, steam-to-carbon ratio, compressor surge limitation, etc. The aim is to achieve maximum efficiency of power generated within these constraints. Governing equations of MCFC-HS modelling are given. An operational line of the MCFC-GT system is presented which fulfils several constraints (temperature difference, cell temperature, etc.) The system is able to achieve efficiency of more than 62% even in part-load operation.

Abstract

The realization of digitalization in production companies – currently also referred to as Industry

4.0 – aims for reduction of internal value creation costs as well as costs for intercompany

collaboration and plays a key role in their current strategy development. However, related

strategy research still lacks to provide operationalized digitalization methods and tools to

practitioners with scientific rigor as well as real-world relevance. To challenge this status

quo, we present a scientifically grounded 14-step procedure model including 11 practically

tested tools, developed specifically for real-world application. The model leads practitioners

from their first contact with industrial digitalization, through the maturity assessment of

143 digitalization items, until the implementation of a KPI-monitoring system and a continuous

improvement process. We applied and re-worked the procedure model during three

years of application. Validation and Feedback from practitioners and scholars indicate, that

the model drives strategy development towards objective and data-based decision making

and increases stakeholder engagement in organizations considerably.

Abstract

The energy strategy of Ukraine until 2035 forecasts that 12% of energy production will be from biomass. Currently, the share of biomass energy in the total structure of energy supplies in Ukraine is only 2%. After the Russian invasion of Ukraine, the diversification of the energy sector became extremely important. Rising fuels prices, problems with the fuel supply and the availability of agricultural biomass make biofuels an attractive alternative to fossil fuels. Ukraine has the potential to develop the production and use of all types of biofuels: solid, liquid and gaseous. Currently, the existing capacity and feedstock potential of biofuel production in Ukraine have not been fully realized. The experience of leading countries in the field of biofuel production shows that at the basis of the governments’ growing commitment to developing the biofuel sector is a desire to diversify the energy supply, create new jobs, improve energy security and reduce carbon dioxide emissions and other gases that contribute to global warming. The aim of the study is to construct the theoretical and practical principles of the implementation of the strategy for biofuel production from agrobiomass in Ukraine. We came to the conclusion that the trigger for the development of the bioenergy industry is the adoption at the state level of the strategy for the production of biofuels from agrobiomass. The implementation of the strategy for biofuel production will help to increase the production and use of biofuels that will strengthen Ukraine’s energy sector, help to stabilize fuel prices and will have a positive impact on the economic development of the country.
