Contoured Bode Plot based Robust Decentralised Controller for Three-Input Integrated Dc-Dc Converter
Authors: Manogna M. , Reddy B. Amarendra , Padma Kottala
Published: December 2024

Designing controllers for multi-input multi-output (MIMO) integrated Dc-Dc converter is complicated due to shared elements, integrated structure, and relation between the input and output variables of the converter. In this work, a robust PID controller based on a Contoured Robust Controller Bode Plot (CRCBP) is designed for control of the three-input integrated Dc-Dc (TIID) converter. This method combines robust control with classical loop-shaping. In this procedure, the outlines of the robust metric are drawn on the Bode charts of the controller, and the controller is adjusted till its frequency response does not cross the contours of the robust metric to meet the stability and performance goals. The TIID converter is modeled using state-space analysis and a Transfer Function Matrix (TFM) is acquired from the small signal continuous time model. The interactions between the inputs and outputs of the converter are quantified and input-output pairing is identified by Relative Gain Array (RGA). The input-output pairing suggested by RGA decides the controller structure. Further, the weight functions (loop-shaping filters) are designed based on the TFM which represents the desired robustness and performance of the controller. These weight functions are used to define the robust metric for the controller design. Based on this, the CRCBP controller is designed iteratively. A standard TIID converter of power rating 288 W with input voltage levels of 24V, 30V, and 36V is considered to show the effectiveness of the proposed controller under varying operating conditions. The real-time simulation results disclose the proposed controller's superiority over the existing approaches in the literature.

Public Facilities in the Context of Sustainable Development: A Multiple-Study of Academic Libraries
Authors:   Faculty of Architecture, Cracow University of Technology, Gierbienis Marcin
Published: December 2024

We live in a time when thinking about the environment today means thinking
about the future of a generation. In an increasingly urbanised space, not only
are we gradually losing contact with nature, but we can also see that the impact
of development on it is often negative and irreversible. A sustainable approach
to design, which places greater emphasis on building design, use, and good
practices, seems essential. Libraries, whose existence is strongly tied to their
educational mission, play a very important role. By remaining repositories
of knowledge and places of activity, but also by their pro-environmental
orientation, they can become a model of contemporary architecture. The aim of
this paper is to present academic libraries that play a special role as the focal
point of a campus plan, offering both a rich programme of cultural events and
a place to study.

Authors:   Department of Geoengineering and Water Management, Faculty of Environmental and Energy Engineering, Cracow University of Technology, Twaróg Bernard
Published: December 2024

With the increase in the share, with variable production of renewable energy
sources in power systems, many studies and expert opinions have appeared
in scientific research and the energy market to determine their optimal
technological and locational cooperation. Modern Portfolio Theory (MPT) has
often been applied in this context. However, some key aspects important in
energy planning have not been included in these analyses. This article presents
the use of the Markowitz model (Modern Portfolio Theory) in analyzing the
hybrid co-option of selected energy sources, assuming two approaches that
take into account gross potential and constraints imposed by technological
capabilities. The goal is to determine the optimal value of the participation
rate of wind farms and solar farms in the energy production co-op assuming
the minimization of risk. The value of risk here is determined by a measure of
dispersion for the delivery of a certain amount of energy. The results of the
analysis are the determination of a map of optimal values of participation factors
between the components of the hybrid energy complex for the area of Poland.
Analyses were made for gross potential, showing the possibilities of maximum
energy production, and for potential limited by technological possibilities.
The study used data characterizing the potential of wind energy and solar
energy and temperature. The data used in the analyses are publicly available
for research purposes. The analyses were supported by graphs and commentary.

Published: December 2024

This paper discusses the history and, most importantly, the spatial development
and the urban layout of the town of Zaklików. Zaklików is an early-modern-
-period town founded in 1565 by Stanisław Zaklika of the coat of arms of Topór,
probably on previously undeveloped land on the border of the Lublin Upland and
the Sandomierz Basin, in Solska Forest. The town was founded on the basis of
a charter issued by King Sigismund II Augustus.
The aim of this paper is to present the results of preliminary research on
the urban composition of the town from its foundation period. The research was
based primarily on a review of the literature, archival queries, as well as fieldwork.
The urban structure of the town was analysed and compared to models of other
early modern Polish towns. On this basis, Zaklików was classified in a specific
group of layouts, characterised as a private town, an economic layout with an
early modern use programme, but that still used traditional planning methods.

Published: December 2024

The evolution of sustainable architectural development in Vietnam demonstrates a strategic response to climate change and environmental challenges. The Vietnamese government has implemented key policies, including the establishment of the Department of Environment in 1990 and the Law on Environmental Protection in 1993. Regulations such as QCXDVN 09:2005 and QCVN 09:2017/BXD emphasize energy-efficient construction. At COP26, Vietnam pledged to achieve net zero emissions by 2050 and is actively participating in a fair energy transition partnership (JETP) with G7 countries. To support these goals, Vietnam has developed green building evaluation systems like LEED, EDGE, and LOTUS, promoting renewable energy use and resource-efficient materials. This paper presents the guidelines for the new-built objects to meet the sustainability requirements based on case studies. This proactive approach not only addresses environmental concerns but also fosters economic growth and sustainable urban development.
Evolution of public library architecture as based on the work of Alvar Aalto and the extension of the Seinäjoki library
Authors:   Faculty of Architecture, Brno University of Technology, Šlapeta Vladimir , Gierbienis Marcin ,   Cracow University of Technology, Faculty of Architecture
Published: December 2024

The end of the 20th century was a period of dynamic change for libraries. The growing popularity of new media, the development of television and especially the Internet, changes in the way societies, economies and industries functioned have all had a significant impact on the way libraries are run. Just as libraries used to be important places for acquiring knowledge, for accessing information, today the flow of information is different, and the book as a product is no longer as attractive, but also, even in the context of libraries, has ceased to be the main element of their operation. Institutions have found a solution to this problem by attracting audiences with both a more interesting and varied cultural offer.

The paper discusses how library architecture has evolved over the centuries on the case study of the extension of the public library in Seinäjoki. Finnish city is also known for the work of Alvar Aalto, who created a civic centre that also became the site of one of the most interesting libraries. Aalto was passionate about this form of use, which accompanied him through various stages of his career. Given that the old building and the new one were built less than half a century apart, it is interesting from a research point of view to compare their architecture, aesthetics and approach to spatial organisation.

The article presents two important strands of research: the preserved paintings in the present attic of the Latin Rite Archcathedral Basilica in Przemyśl and the polychromy on the stone blocks in the foundation part of this temple. The existing paintings of significant cultural value were made in the late medieval period, an era when the Przemyśl Cathedral had Gothic forms, and the existing paintings circled the walls of the temple below the Gothic wooden ceiling. Based on the current state of research and the extent of damage to the paintings, it was only possible to interpret and read the paintings piecemeal. The article includes their photographs and discusses the painted scenes and ornamentation along with their psychological context. Polychromes in part of the foundation walls of the chancel of the Przemyśl basilica were also studied. The results of the research could confirm the reuse of stone blocks for the construction of the walls of the cathedral’s chancel. In addition, the chemical composition of the mortar structures and polychrome was given. The data provided insight into the mortar and paint technologies used in the medieval era in Przemyśl.

Published: December 2024

The change process is not easy; effort is required to implement a change in any system. Saudi Arabia's Ministry of Education is working to bring a change to their education system by implementing cooperative learning. This approach is different from traditional learning, so there are different barriers faced by teachers, students, and administrators. This study focuses on analyzing the perceptions of teachers which may act as barriers while they implement cooperative learning in schools in Saudi Arabia. This study aims to investigate the level of preparedness of teachers while implementing cooperative learning; the professional perspective of teachers regarding cooperative learning; and the perception of teachers regarding the benefits and use of cooperative learning. The study used a quantitative research design and a survey was distributed among the teachers working at a public school in Saudi Arabia. Teachers’ preparedness, perception, and personal perspectives were tested and quantitative data revealed the barriers limiting the implementation of cooperative learning in schools. Findings can be utilized by policy makers and administrators to dictate necessary changes in the system which will help in the effective implementation of cooperative learning. The policymakers may need to work on the policy framework to equip teachers to mitigate these barriers.

The Nurse Managers’ Knowledge and Attitudes Toward Transformational Leadership Styles in Ondo State, Nigeria
Authors: Adeyemo Cecilia Olusolape , Bimray Portia , Bimerew Million
Published: December 2024

This study investigates the knowledge and attitudes of nurse managers regarding transformational leadership (TL) style in Ondo State, Nigeria. Specifically, it aims to describe the knowledge of top nurse managers about TL and explore their attitudes towards its four components: idealised influence, inspirational motivation, intellectual stimulation, and individualised consideration. Employing an explorative qualitative approach, the study involved in-depth interviews with 12 nurse managers selected through purposive sampling from primary, secondary, and tertiary health facilities. The interview guide was adapted from the Multifactor Leadership Questionnaire (MLQ), featuring open-ended questions to elicit detailed responses. Data were analysed using thematic analysis with Atlas Ti 9 software. Findings revealed that while participants demonstrated a basic understanding of leadership, their knowledge of TL style was superficial, often conflating it with democratic leadership. Their attitudes towards the TL components were similarly limited. For example, participants emphasised teamwork and delegation under idealised influence but lacked deeper application of ethical and visionary attributes. Inspirational motivation, intellectual stimulation, and individualised consideration were inconsistently implemented, with respondents displaying only partial understanding of these concepts. The study highlights the need for comprehensive training to enhance nurse managers’ understanding and practice of TL style. Such training could improve nursing leadership, foster positive organisational culture, and ensure quality patient care. Recommendations include the development and implementation of TL-focused training programmes for nurse managers across health institutions in Ondo State.
Government Agricultural Expenditure and Sustainable Development Goal One in Nigeria
Authors: Oshim Judethadeus Chukwuebuka , Nnajieze Ifeyinwa Elizabeth
Published: December 2024

This study investigates the impact of government expenditure on agriculture, inflation, exchange rates, and interest rates on poverty in Nigeria from 2000 to 2022, using panel regression analysis to explore the relationship between these variables and the Poverty Headcount Ratio (PHR). The findings reveal that government expenditure on agriculture has a significant positive effect on poverty levels, indicating that higher agricultural spending may inadvertently contribute to increased poverty in the country. While inflation and exchange rates do not significantly affect poverty, interest rates show a positive and significant relationship with poverty, suggesting that higher interest rates exacerbate poverty by limiting access to affordable credit. The study highlights the importance of enhancing the efficiency of agricultural spending and reducing interest rates to alleviate poverty. Additionally, it emphasizes the need for comprehensive economic policies and institutional strengthening to address the complex factors influencing poverty in Nigeria. The study contributes to the existing body of knowledge by providing new insights into the mixed effects of agricultural expenditure and the significant role of interest rates in poverty dynamics. The findings offer valuable recommendations for policymakers aiming to reduce poverty and promote sustainable development in Nigeria.

Published: December 2024

The hospitality industry is undergoing rapid transformation due to technological advancements, shifting consumer behaviors, and growing sustainability concerns. These changes significantly influence Home Economics and Family Consumer Sciences (FCS) education. However, the integration of these industry trends into educational curricula remains inadequate, leaving graduates ill-equipped for dynamic industry demands. This study examines the relationship between hospitality industry trends and the effectiveness of FCS curricula, focusing on sustainability, technological advancements, and consumer behavior. It hypothesizes that aligning FCS education with hospitality trends enhances curriculum relevance, teaching methodologies, and graduate employability. The research employed a cross-sectional survey in Oyo Town, Oyo State, Nigeria, targeting educators, hospitality professionals, and families involved in consumer sciences. A multi-stage sampling technique was used to select 220 respondents, stratified by local government areas, profession, and demographics. Data collection involved structured questionnaires and interviews, with descriptive and inferential statistics such as chi-square and regression analyses applied to test hypotheses. Results reveal that 70% of respondents agreed sustainability practices are essential in FCS education, while 65% emphasized the need for incorporating technological advancements. Regression analysis showed a significant positive impact (p < 0.001) of hospitality industry trends on FCS curriculum effectiveness. Furthermore, personalized services and consumer behavior trends were highlighted as critical areas for curriculum innovation. To address gaps, the study recommends integrating sustainability and technology-focused modules into FCS curricula and fostering academia-industry collaborations. These steps ensure that education adapts to industry dynamics, enhancing graduate readiness for evolving professional and personal challenges. The findings underscore the critical role of FCS education in equipping students with relevant, future-ready skills.

Rad analizira utjecaj promjene specifičnog otpora tla na veličinu struje jednopolnog kratkog spoja. Polazna pretpostavka je da su svi elementi strujnog kruga konstantni pa na vrijednost struje kratkog spoja djeluje promjena vrijednosti otpora rasprostiranja uzemljivača. Proračuni su izvedeni pomoću programa TOKSwin na stvarnoj mreži 35 kV grada Osijeka.
Neka razmišljanja o budućnosti mreže 220 kV
Authors: Cvetković Zorko
Published: December 2024

Prijelazom na napon 400 kV donesena je odluka da se više ne proširuje mreža 220 kV osim nužnih zahvata u postojećim postrojenjima. Međutim povremeno se ta mreža ipak proširuje, a javljaju se novi prijedlozi. Pokazuje se da su ta proširenja ponekad upitna i da bi trebalo pristupiti izradi studije koja bi sveobuhvatno rješila budućnost mreže 220 kV.

Published: December 2024

A new tariff scheme for electricity sale has been adopted in Slovenia. This scheme is supported by regulations that introduce current limiting circuit-breakers in low voltage wiring systems. The tasks of these device are limitation of the peak demand and protection of consumers against overloading and short circuit faults. The recent developments of communication systems have also given a possibility of remote control of current limiting circuit-breakers and thus indirectly of the consumers' behaviour. The paper describes various types of low voltage current limiting circuit-breakers, methods of their selection and installation, as well as possibilities of the remote control.

Buduće emisije ugljičnog dioksida iz hrvatskog elektroenergetskog sustava
Authors: Božičević Maja , Tomšić Željko , Jakšić Dražen
Published: December 2024

Hrvatska je jedna od zemalja potpisnica Protokola iz Kyota koji ju obvezuje da emisiju stakleničkih plinova smanji za 5 % u odnosu na razinu emisija iz bazne godine. Protokol će stupiti na snagu tek nakon što ga ratificira 55 zemalja potpisnica koje sudjeluju s 55% u emisijama stakleničkih plinova zemalja obuhvaćenih Aneksom B Protokola iz Kyota. Hrvatski sabor do danas nije ratificirao Protokol. Međutim, iako ne predstavlja zakonsku obvezu, Protokol određuje važan okvir za planiranje razvitka svake države, pa tako i Hrvatske. Očekuje se da će hrvatske vlasti izabrati 1990. kao baznu godinu u odnosu na koju će se analizirati buduće emisije stakleničkih plinova. Kako proizvodnja električne energije igra značajnu ulogu u ukupnoj emisiji stakleničkih plinova, mogućnosti smanjenja tih emisija koje potječu iz elektroenergetskog sustava moraju se razmotriti s posebnom pažnjom. Provedena je usporedba tri hipotetska razvojna scenarija hrvatskog EES-a te su razmotrene poteškoće pred kojima će se naći sustav u slučaju da će se ukupna emisija iz sustava morati smanjiti za 5% u odnosu na emisije iz 1990. Kako nuklearne elektrane predstavljaju razvijenu i gospodarski prihvatljivu tehnologiju za proizvodnju električne energije čiji pogon ne uzrokuje emisiju ugljičnog dioksida, razmotrena je mogućnost smanjenja buduće emisije ugljičnog dioksida iz hrvatskog elektroenergetskog sustava uporabom nuklearne energije. Prikazane su tri razvojne opcije sustava koje se međusobno razlikuju po broju nuklearnih elektrana u pogonu, kao i emisije ugljičnog dioksida u svakoj od opcija. Izračunato je smanjenje emisije ugljičnog dioksida koje bi bilo rezultat zamjene dijela elektrana loženih fosilnim gorivom nuklearnim elektranama. Procijenjeno je koliko je nuklearnih elektrana u pogonu potrebno da bi se u razdoblju do 2030. godine emisija ugljičnog dioksida iz hrvatskog EES-a zadržala na razini koja je za 5 % niža od razine iz 1990. godine.

Glavni sustavi plinske turbine MS6001FA u TE-TO Zagreb
Authors: Šander Miroslav
Published: December 2024

Plinska turbina MS6001FA od 70 MW je ugrađena u kombikogeneracijsko postrojenje u TE - TO Zagreb. Turbina je kompleksno postrojenje koje uključuje čitav niz sustava i podsustava. Iako se pogonska stanja turbine kontroliraju i povratni signali šalju u upravljački sustav SPEEDTRONIC pa se čini da su svi drugi sustavi od drugorazredne važnosti, ovdje želimo pokazati kako upravljački sustav ne može funkcionirati i djelovati bez ovih drugih sustava te da su oni za ispravan pogon turbine isto tako važni kao i upravljački sustav. Naravno da se ovdje ne mogu obuhvatiti svi sustavi niti podsustavi, a i samoj podjeli se može pristupiti na drugi način. Ovdje govorimo o sustavu ulja za podmazivanje, sustavu hidrauličkog ulja i ulja za izvrštavanje te uz njih vezane; ulazne privodne lopatice (IGV), sustavu plinskog goriva, sustavu tekućeg goriva. Ulazne privodne lopatice (IGV), sustav plinskog goriva, sustav tekućeg goriva, mogu se sami za sebe uzeti kao glavni sustavi plinske turbine, što ovdje nije učinjeno jer bi tada te sustave morali puno detaljnije obraditi. Uređaji za praćenje i vodenje turbine su oni koji direktno služe računalnom sustavu SPEEDTRONIC, a koji obuhvaćaju sve komponente koje se koriste za praćenje i pri vodenju plin- ske turbine, tj.: mjerenje temperature, indikaciju vibracija, mjerenje brzine vrtnje, detekciju plamena, paljenje. Takoder je obraden sustav za upuštanje.
