Description:

The paper proposes a multi-layer supervisory architecture for integrated control systems in road vehicles. The role of the supervisor is to coordinate active control components and provide priority among them. The supervisor has information about the current operational mode of the vehicle and it is able to make decisions about the necessary interventions into the vehicle components and guarantee the reconfigurable operation of the vehicle. The decisions of the supervisor are propagated to the lower layers through predefined interfaces encoded as suitable scheduling signals. The contribution of the paper is the application of the LPV methodology in a design case study in which an integrated control of four wheel independently-actuated electric vehicle with active steering system is developed.

Description:

The research examined the environmental impact of listed and unlisted buildings from different periods. Compliance with strict standards encourages professionals and researchers to improve the environmental impact of buildings by examining the root causes of problems in more depth, which requires understanding and analysing the entire life cycle of buildings. People’s attitudes have changed, both in terms of raw materials and energy consumption. The article is a literature review of research published in recent years in the field of environmental impact assessment of historic (and in some cases younger) buildings. It analyses and summarizes the questions that researchers sought answers to, the methods they applied, the data and databases they used, the calculations they performed and the results they achieved. When collecting the analysed sources (research articles), the goal was to find sources presenting a large number of case studies. The case studies were classified according to geographical location; the historical age of the buildings and, in this context, the materials and structures used; the extent of the expansions, transformations and modernizations carried out. The literature review provides insight into the current state of science on how to quantify the value of historic buildings. Based on the experiences gained, it is also possible to formulate and conduct a domestic research. The article contributes to a deeper understanding of the calculation of the environmental impacts of historic buildings, which can help in compliance with legislation, energy and environmental requirements, and in the protection of existing buildings.

Description:

Europe's energy security is a very relevant and debatable topic today, especially since the Russia Ukraine conflict energy security is becoming a challenge for Europe. Many countries in the European Union do not have sufficient fossil energy resources and are dependent on neighboring, energy-rich countries. Such dependence on other countries in the EU is useless and even dangerous, both economically and politically or in terms of energy security. The EU faces serious energy security challenges due to its high dependence on external energy exporters. Countries that export energy resources can manipulate them and exert both economic and political pressure. The main problem is how to assess the energy transformation opportunities while strengthening energy security. Currently, there is a lack of research that would propose solutions to increase energy security on a national scale. Renewable energy solutions would allow achieving these goals, thus creating synergy with economic benefits. During the study, energy business representatives were interviewed in order to understand market trends and attitudes. When processing the data using the factor analysis method, results were obtained that reveal a clear connection between renewable energy and energy security. Research shows that geopolitical security becomes an important aspect when the volume of renewable energy deployment increases.

Minimal Volume Simplex (MVS) Polytopic Model Generation and Manipulation Methodology for TP Model Transformation

Péter Galambos József Kuti Peter Baranyi

Publication Name: Asian Journal of Control

Publication Date: 2017-01-01

Volume: 19

Issue: 1

Page Range: 289-301

Description:

The vertices of a polytopic LPV/qLPV model determine the feasibility of any linear matrix inequality (LMI) based control design as well as the achievable control performance, since the polytope typically includes not only the actual system dynamics. This paper proposes a powerful method to determine suitable polytopic qLPV Tensor-Product model forms that allows for fine tuning through constraints on the locations of the vertices. The paper shows that these tuning methods are capable of effectively influencing the closed-loop control performance results from LMI-based multi-objective optimisation. The advantages of the proposed methods are their tractability, low computational complexity, as well as their determinism. The key idea behind the proposed methods is to determine vertices in each decoupled parameter-dimensions of the TP model in such a way that they form a minimal volume enclosing simplex fulfilling further fine tuning conditions on its shape. This is achieved based on the extension of the Minimal Volume Simplex Analysis (MVSA) method, where the volume of the enclosing simplex polytope is minimized by applying Sequential Quadratic Programming with majorization minimization strategy extended with a set of additional constraints influencing the location of certain vertices according to physically established considerations. Besides the comprehensive presentation of the proposed design methodology an expressive numerical example is provided to demonstrate its effectiveness and usability.

Description:

Footwear design, especially the curvature of carbon plates, may influence fatigue perception, but few studies have integrated footwear features into fatigue prediction models. This study aimed to develop a hybrid CNN-LSTM model to predict runners’ fatigue states and evaluate the impact of footwear characteristics on fatigue perception. Twelve male marathon runners (age = 21.8 ± 1.3 years; body mass = 59.1 ± 4.1 kg; height = 168.9 ± 2.2 cm; and weekly mileage = 68.8 ± 5.5 km) participated. They wore two types of carbon-plated shoes (flat plate, FP, and curved plate (CP)) and ran at a steady pace (Borg score 13) until a Borg score of 16 or 85% of maximum heart rate was reached for 2 min. EMG signals and physiological data were collected during treadmill running. A hybrid CNN-LSTM model was trained with and without footwear features to predict fatigue states. The model with footwear features achieved 85% accuracy, compared to 69% without. Curved carbon plate (CP) shoes delayed semi-fatigue onset, indicating better initial support, but the time to full fatigue was similar for both shoe types. The CNN-LSTM model effectively predicted fatigue states, with significant improvement when footwear features were included. Footwear design, particularly carbon plate curvature, influenced fatigue perception.

Description:

The aim of the Traveling Salesman Problem (TSP) is to find the cheapest way of visiting all elements in a given set of cities and returning to the starting point. In solutions presented in the literature costs of travel between nodes (cities) are based on Euclidean distances, the problem is symmetric and the costs are constant. In this paper a novel construction and formulation of the TSP is presented in which the requirements and features of practical application in road transportation and supply chains are taken into consideration. Computational results are presented as well.

Issue: Unknown

Page Range: 85-89

Description:

The semantic synthesis of intelligent space, emotional-behavioral modeling and cognitive infocommunications is a promising approach in the multidisciplinary field applied for ambient assisted living. The ambient assisted living application can be regarded as a complex cooperation and communication of different kinds of intelligent entities in a well-limited, semi-structured environment. The intelligent space aspect deals with the possible cooperation of intelligent entities as matching between needs and capabilities. The emotional-behavioral modeling handles the internal states and attitudes of the entities. The cognitive info-communications aspect deals with communication situations and processes between the entities. The semantic information framework is intended to provide a synthesis of the different fields in order to unite the represented knowledge in the form of information transfer between the field scopes. © 2013 IEEE.

Issue: Unknown

Page Range: 245-280

Description:

This study examines the complex interaction between social multi-dimensionality and green energy financial literacy in Mexico. Drawing on a mixed-methods approach with quantitative analysis of Mexican national survey data and qualitative interviews with stakeholders, this research examines how socio-economic status, place, education levels, and indigenous identity intersect to form barriers to green energy financial literacy. The findings reveal wide disparities in the availability of information on green energy finance, and indigenous, rural, and poor communities report significantly lower levels of financial literacy for renewable energy investment. The research adds to the pool of knowledge on how social disparities perpetuate environmental and economic disparities in emerging economies in their developmental path towards sustainable energy infrastructure.

Description:

Purpose: The aim of this tutorial is to support speech language pathologists (SLPs) undertaking assessments of multilingual children with suspected speech sound disorders, particularly children who speak languages that are not shared with their SLP. Method: The tutorial was written by the International Expert Panel on Multilingual Children’s Speech, which comprises 46 researchers (SLPs, linguists, phoneticians, and speech scientists) who have worked in 43 countries and used 27 languages in professional practice. Seventeen panel members met for a 1-day workshop to identify key points for inclusion in the tutorial, 26 panel members contributed to writing this tutorial, and 34 members contributed to revising this tutorial online (some members contributed tomore than 1 task). Results: This tutorial draws on international research evidence and professional expertise to provide a comprehensive overview of working with multilingual children with suspected speech sound disorders. This overview addresses referral, case history, assessment, analysis, diagnosis, and goal setting and the SLP’s cultural competence and preparation for working with interpreters and multicultural support workers and dealing with organizational and government barriers to and facilitators of culturally competent practice. Conclusion: The issues raised in this tutorial are applied in a hypothetical case study of an English-speaking SLP’s assessment of a multilingual Cantonese-and English-speaking 4-year-old boy. Resources are listed throughout the tutorial.
