Implementation of measurement uncertainties into vehicle noise regulation
Authors: Berge Truls , Gerhard Hans-Martin
Published: February 2023

The current vehicle noise regulation UN R51.03, does not provide specific considerations for the measurement uncertainties related to the measuring method for external pass-by noise. The measurement method is based on the ISO Standard ISO 362-1:2007. While the ISO system mandates a
detailed description of the expected uncertainties, the UN-ECE has not overtaken these uncertainty considerations, as the application of the test method is limited to type-approval and conformity of production measurements, both under control of the vehicle manufacturer in agreement with a
type- approval authority. The UN ECE Working Party on Noise and Tyres (GRBP) in Geneva established in 2019 an Informal Working Group on Measurement Uncertainties (IWG MU), to evaluate the measurement uncertainty in general and to propose amendments to regulations to reduce the measurement
uncertainty, starting with the most important sound emission regulations UN R51.03 (vehicles) and UN R117.02 (tyres). This paper describes the principal work of the IWG concerning the contribution of the different parameters to the overall expanded uncertainties when testing vehicles according
to the specifications in UN R51.03. The identified main contributors to the overall measurement uncertainties are variations due to the test track (site-to-site) and air temperature effects (day-to-day).
Strategic distribution of resonators' parameters for broadband vibration mitigation
Authors: Alves Pires Felipe , Boukadia Regis , Deckers Elke , Desmet Wim , Claeys Claus
Published: February 2023

Locally resonant metamaterials have recently come to the fore as novel lightweight and compact Noise, Vibrations and Harshness (NVH) solutions. They can be designed/obtained by assembling nominally equal resonant elements, which are tuned to the desired frequency range, onto a host
structure in a sub-wavelength manner. This combination leads to tunable frequency ranges, known as stop bands i.e. frequency regions where free wave propagation is not allowed. Nonetheless, these stop bands are typically only effective in a limited frequency region. In order to broaden the
frequency range of noise and vibration reduction, an optimization procedure could be applied in order to obtain the ideal distribution of resonance frequencies and masses to achieve a minimal sound radiation over a certain frequency region. However, this approach typically requires a considerable
computational time. For this reason, this paper proposes a set of guidelines that define a strategy for broadband NVH reduction without the use of optimization. The proposed strategy is applied to a finite plate with a predefined added grid for the resonator positions. The performance of the
strategy is numerically analyzed by assessing the vibration response of the plate for multiple excitation locations and within different frequency ranges. The obtained responses are then compared to the response of the plate with an optimized grid of resonators. This study shows that the proposed
strategy leads to a reasonable vibration reduction with similar levels with respect to the response obtained from optimization.
Sound Radiation Estimate from Vibration Measurements With Multiple Cameras
Authors: Guernieri Gianluca , Gardonio Paolo , Rinaldo Roberto , Fusiello Andrea , Turco Emanuele
Published: February 2023

This paper presents experimental results on the estimate of the sound radiation by a thin flat plate from flexural vibration measurements taken with multiple cameras. The study considers the sound radiation into free-field by a baffled rectangular plate fixed on a rigid frame. The plate
is excited by a tonal point force exerted by a shaker at the first three resonance frequencies of the plate flexural response. The resulting vibration field is measured with a set of six cameras suitably synchronised. More specifically, 3D point tracking is implemented on a regular NxM grid
of small circular points marked on the plate. The transverse displacements at these points are thus reconstructed from triangulation with multiple (i.e. more than 2) view-points. The transverse displacements are then used to derive the sound radiation from a direct boundary integral formulation.
More specifically, for the flat rectangular plate at hand, the sound radiation is derived from the Rayleigh integral, which is approximated into a finite sum over the mesh of rectangular elements centred at the NxM grid of points depicted on the plate. The flexural vibration field and the
sound radiation field derived from the camera measurements are contrasted with measurements taken with a laser vibrometer and microphone-scanner probe. The initial results presented in this paper demonstrate the feasibility of the proposed measurement approach at low audio frequencies.

Published: February 2023

Green areas suffer the growing influence of urbanization and may benefit from the use of passive acoustic monitoring (PAM) which can provide biodiversity estimation and conservation especially in fragile environments such as urban parks and protected areas. A network of low-cost sensors
has been distributed over an area of approximately 20 hectares at the Parco Nord of Milan, Italy, to highlight areas with different acoustic characteristics. The audio files analysed in this study were recorded at 16 sites on four sessions between 25 May and 29 June 2015 from 06:30,a.m. to
10:00 a.m.. Seven eco-acoustic indices have been computed and analysed. A map of eco-acoustic indices has been built and validated by comparing the results with an aural survey aimed at determining the sound components at each of the sixteen sites (biophonies, technophonies and geophonies).
This approach may represent a useful tool for an integrated approach aimed at conservation planning and development decisions.

Authors: Youdale Chris , Shilton Simon , Trow James
Published: February 2023

The United Kingdom Department for Food and Rural Affairs (Defra) commissioned a series of studies investigating the sensitivity of the CNOSSOS-EU noise assessment method. CNOSSOS-EU presents challenges in terms of input data accuracy and availability. For this reason, the studies were
commissioned to support data decision making and quantify potential uncertainty in Defra's national noise model. A study was undertaken to identify how the selection of a ground cover dataset may influence calculated noise levels using the CNOSSOS-EU noise assessment method and computational
load. Acoustic test models were developed incorporating prepared ground cover datasets based on CORINE Land Cover 2018, CEH Land Cover Map 2019 and OS Mastermap Topography. Noise calculations in accordance with CNOSSOS-EU were carried out for rural and urban/suburban propagation environments.
A statistical analysis of the differences between each selected dataset was then undertaken. The paper discusses the findings of this analysis along with generic rules which were identified with respect to modelling ground effect using CNOSSOS-EU.
Simulating Changes in Aircraft Noise at Heathrow Airport during the 2020 Covid-19 Lockdown
Authors: Trow James , Phillips Jonathan , Vinci Davide
Published: February 2023

Global restrictions on domestic and international travel introduced in March 2020 as a result of the Covid-19 pandemic resulted in a significant reduction in air traffic movements around the world. This paper presents the findings of research carried out at London Heathrow Airport exploring
the day-by-day changes in aircraft noise exposure and event levels over the period March 2020 to June 2020. The research was carried out using validated modelling of aircraft procedures and noise profiles alongside radar data obtained from the airport. This allowed trends in metrics such as
LAeq, N65, and overflight to be considered in the form of contours, and at community locations. This was facilitated using geospatial databases and interactive dynamic reporting toolkits. The research has allowed estimates to be made of the point where aircraft noise at Heathrow Airport reached
a minimum. It also provides some helpful insight as to the potential of generating daily noise exposure data and the advantages, and disadvantages of modelling using radar data.
Finite Element modeling of force amplification at the spindle due to a tire's cavity mode: experimental verification
Authors: Choi Won Hong , Bolton J. Stuart , Choo Kyosung , Black Matthew
Published: February 2023

Reduction of tire-road noise is an important issue when developing luxury cars and electric vehicles. In this context, the air-cavity mode is an important source of spindle forces transmitted to the suspension that then increase interior noise levels. When a tire rotates, the cavity
mode near 200 Hz splits into two adjacent modes due to a Doppler effect and tire deformation. That split can lead to increased levels of both longitudinal and vertical spindle forces at the spindle since the two acoustic modes each contribute to both forces when the tire rotates. Thus, it
is important to develop tools to identify the contributions of the split air-cavity modes to the spindle force. A FE simulation of the spindle force for a steady-state rolling has been verified by a comparison with laboratory test results obtained by using a wheel-force transducer mounted
on Purdue's Tire Pavement Test Apparatus. It was observed that the frequency split expands as the rotation speed increases and that the vertical spindle force increases when aligned with an odd-numbered circumferential structural mode. By using the correlated simulation model, parametric studies
have been carried out focused on minimizing the vertical spindle force due to air-cavity mode near 200 Hz.
A study of different tapering windowing functions and referencing curve for the improvement of sound field using wave-field synthesis
Authors: Puri Amrita , Kumar Akash
Published: February 2023

Wavefield synthesis is a well-known sound field reproduction technique. The correct synthesis of the desired sound field ideally requires a continuous source distribution over an enclosed surface. Due to practical limitations, a finite length of secondary source array is used. This
results in distortion in the reproduced sound field due to the diffraction effect from the edge loudspeakers. To alleviate this problem, tapering window functions are utilized. In this paper, the influence of various windowing functions on the reproduced fields for different secondary source
geometry and virtual source type is studied, and different parameters are used to make a quantitative comparison between the performance of different windowing functions. Further, the effect of the different referencing curves for the synthesis of correct amplitude is also presented. From
the simulation results, it was found that the Tukey window function provides a wider sweet spot area with a minimal amplitude ringing effect. The selection of a proper referencing curve depends on the array geometry and the type of virtual source.
Towards reconstruction of acoustic fields via physics-informed neural networks
Authors: Silva Garzon Camilo Fernando , Bonnaire Philip , Doan Nguyen Anh Khoa , Niebler Korbinian , Silva Camilo Fernando
Published: February 2023

Acoustic measurements, obtained by microphones positioned at strategic places, are of great utility for the monitoring of a given acoustic system and for its protection in case large pressure fluctuations are measured. Such strategies are reliable as long as the microphones are properly
positioned, which is not evident: in some cases the excited acoustic modes are not known beforehand. In this work, we proposed a method based on physics informed neural networks (PINN) in order to reconstruct the entire acoustic field of a given acoustic element, provided some acoustic measurements
at some few locations. Such a method makes use of a feed forward neural network, where the cost function is taken as the residual of the acoustic wave equation. Such a residual is computed exploiting the automatic differentiation property of neural networks, in order to obtain the corresponding
spatial and time derivatives. Additionally, the measurements of the aforementioned microphones are gathered and used also for the calculation of additional terms in the PINN cost function. By doing so, the most adequate acoustic state is obtained, which satisfy both measurements and the acoustic
wave equation. In other words, the acoustic field within the system is reconstructed.
Measurement of acoustic source data of taxiing aircraft for noise modelling
Authors: Gibbs George
Published: February 2023

Noise from airport ground activities can be a significant contribution to the ambient sound climate in communities close to airports. The shortfall in robust acoustic source data for taxiing aircraft is a limitation to the accuracy of noise modelling supporting impact assessments associated
with changes in airport infrastructure and operations. The aim of this project was to develop a robust measurement methodology for the purpose of obtaining acoustic source data of taxiing aircraft. The project addressed two major challenges: the theoretical principle and experimental design
for characterizing complex moving sources (i.e. the sound power, spectra and directivity); and the practical problems involved in on-site measurement. The theoretical principle is to of consider an aircraft, moving in-line past a microphone, as reciprocally equivalent to a stationary aircraft
alongside a line-array of microphones. Increasing the number of microphones in the array is equivalent to increasing the number of angles in the polar distribution plots.
Acoustic Comfort in Hybrid Learning Spaces: Students Perspective
Authors: Elmehdi Hussein , Tato Ania
Published: February 2023

In this paper, we assess the acoustic environment comfort at the University of Sharjah after classes have been reconfigured in response to COVID-19 pandemic protocols, which included reducing the number of seats to comply with social distancing to support the hybrid teaching model.
First, we measured the background noise and reverberation times for the different types of classrooms. The results showed classrooms do not comply with international standards where acoustic comfort indicators are higher than the recommended values. For example, the background noise levels
were found to range from 43.9 - 49.6 dB(A), which is higher than the recommended WHO limits. To evaluate the acoustic comfort from the perspective of the main stakeholder; the students, we conducted a subjective survey to evaluate students' perception of the acoustic conditions at the classrooms.
The results indicate that the majority of the students surveyed, (88%) felt that noise in classrooms affected their understanding of the material and communication with the instructor and peers. Noise sources were mainly identified to originate from corridors, maintenance work, and construction
sites within close proximity to the classrooms. Better designs are highly recommended to improve acoustic comfort to ensure an excellent student experience and the best learning environment.

Published: February 2023

The application of sound field control to outdoor live events at low frequencies is a recent one due to increased concerns regarding noise pollution and stronger regulations. Here is presented an overview of the techniques being recently investigated based on model, data or hybrid approaches.
The approaches presented here provide encouraging results but they all deal with the problem at relatively short distances (approximately 100m). Translating these results to larger distances is going to be a challenge as a new set of problems needs to be addressed. An overview of the most
relevant issues encoutered in long range applications such as un-even terrain, properties of the medium, ground and obstacles interacions is also presented.
Quantification of the social cost of noise in France and application of the methodology to the Paris region
Authors: Bernfeld David , Mietlicki Fanny , Thibier Emmanuel
Published: February 2023

The National Agency for Ecological Transition (ADEME) carried out in 2021 a study of the social cost of noise in France that was estimated at 147.1 billion € per year. This cost has been calculated at 97.8 billion € per year for noise generated by transport, at 26.3 billion
per year for neighborhood noise and at 21 billion € per year for noise in the workplace. Health costs are predominant (86% of total) and correspond mainly to the economic valuation of the burden of disease of noise as a result of its adverse effects (annoyance, sleep disturbance, cardiovascular
and metabolic diseases, psychological disorders, learning difficulties, etc.). Secondly, it also includes non-health costs such as loss of productivity and property depreciation. Bruitparif, the noise observatory for the Paris region, has applied and adapted the methodology to the data and
studies available at the regional scale. This results to 42.6 billion € per year, i.e. 29% of the national total. These studies provide reference elements for comparing the financial cost of noise prevention and mitigation measures with the social benefits that are likely to result in
terms of improved well-being for the population and avoided costs for the community.

Authors: Szczepański Grzegorz , Podlesna Marlena , Lada Krzysztof
Published: February 2023

According to the data of the Statistic Poland, noise is the most common harmful factor in the work environment in Poland. In 2020, the number of persons exposed to noise was 181.7 thousand person. Reducing the noise hazard is a primary objective of vibro-acoustic research, and modern
technology allows to achieve this goal in numerous ways. The most important and widespread technique used to reduce the risk of noise exposure of workers is to place noise absorbing or reflecting elements in the workplace. One of the less conventional methods used to produce such elements
is the use of Fused Deposition Modelling. The opportunities that this method presents allow for manufacturing of noise barriers with advanced internal structures, which can reduce the noise transmission or manipulate the propagation of the sound wave. This article describes the study of acoustic
properties of a noise barrier made using a 3D printer. The influence of various 3D printing settings on the obtained acoustic properties of the barrier was investigated. By measuring the acoustic pressure level and the particle velocity in three directions, the acoustic properties of the created
barrier were determined.

Authors: Abid Hussain Ali , Markesteijn Annabel , Karabasov Sergey , Zhang Nick , Azarpeyvand Mahdi
Published: February 2023

In turbomachinery applications such as wind turbines, and aircraft airframe, flow-induced noise and vibration are significant noise sources. There are five main types of airfoil self-noise, with trailing edge noise (TEN) being the most dominant high-frequency broadband noise. The Amiet
TE noise model is a low-order analytical model that requires the surface pressure (SP) near the trailing edge for TEN modelling. The accuracy with which the SP spectrum is calculated determines the accuracy of the TEN modelling. The SP spectrum is calculated using the physics-based TNO-Blake
(TB) Model and its recently produced improved version. Most studies have focused on using the TB model for symmetric airfoil, with little attention paid to modelling the TEN of cambered airfoil. We use TB model variants on the SP spectrum prediction in this study, which are enforced with the
Amiet TEN model for far-field noise modelling. The SP models' source comes from a high-fidelity Large-Eddy-Simulation simulation (LES) based on CABARET method. The simulation is carried out using the NACA65410 airfoil with a chord length of 0.3m and an angle of attack of 0,2, 4, 6, and 8 degrees
at a Reynolds number of 5.2e5. The SP spectrum and velocity spectrum used to improve the TEN model's accuracy for cambered airfoil.
Impact Sound Insulation of thermally insulated Balconies
Authors: Heidemann Lucas , Scheck Jochen , Zeitler Berndt
Published: February 2023

With the increasing urban densification, balconies are gaining in popularity as they improve the living quality in homes. Thermal insulation between balconies and the building's façade is state of the art. In Germany the most popular balcony construction is a reinforced concrete
balcony, separated from the building by a thermal insulation element (TIE), which is meant to reduce the thermal energy loss and thus ensure the sustainability of buildings. The impact sound transmission from balconies, however, is a problem that has not been addressed enough to date. The
main goal of the project is to provide acoustic quantities, e.g., an impact sound reduction, for a TIE that can be used to compare the acoustical quality of products and to predict the impact sound pressure levels within the building using the standard EN ISO 12354-2. Experimental and numerical
studies have been carried out on various ceiling-balcony mock-ups without and with TIEs e.g., by means of experimental modal analysis and finite element models. This paper will show the effect that various parameters have on the impact sound insulation. Additionally, the measurements on the
test set-up will be compared to measurements on building sites.
Noise limits and indicators for intermittent indoor low frequency noise
Authors: Pedersen Frank
Published: February 2023

In Denmark indoor low frequency (LF) noise is measured with the indicator LAeq, 10 min in the frequency range 10-160 Hz. Recent complaints related to short intermittent low frequency noise events (sounds from underground metro, light rail, neighbouring fitness centre...) could indicate
that the correlation between measurements of LAeq and the experienced annoyance is poor. A literature study for LF descriptors and noise limits in other countries has been made. Listening tests on annoyance of various types of intermittent indoor LF noise types is ongoing and the results will
be correlated with alternative relevant noise indicators. The results of the literature study and the listening tests are presented in this paper.
New ASTM ratings for impact noise insulation
Authors: Dong Wayland , LoVerde John
Published: February 2023

New ratings to evaluate impact noise insulation have recently been published as ASTM standards, which are commonly used to evaluate building acoustics measurements in North America. ASTM E3207 defines new ratings for low-frequency impact insulation, defined by the 50-80 Hz third-octave
bands. ASTM E3222 defines new ratings for high-frequency impact insulation, defined by the 400-3150 Hz bands. These ratings are based on the two-rating method of evaluating impact noise isolation proposed by the authors [LoVerde and Dong, J. Acoust. Soc. Am. 141 (2017)]. By evaluating the
low and high-frequency components of impact noise independently, the proposed ratings perform better than existing ratings in terms of correlating with subjective reaction, designing assemblies, and evaluating products and mitigation measures. Motivations, development, and examples illustrating
the use of the new ratings are presented, and suggested classification schemes are discussed.
Factors in Life Expectancy: A Cross-Country Analysis
Authors: Vladimirskaya A. A. , Kolosnitsyna M. G.
Published: February 2023

The objective of the study, selected results of which are presented in the article, is to find the main determinants of life expectancy (LE) using regression analysis methods for four groups of countries classified by income. The criterion for assigning the country to the income group is the indicator of GDP per capita. The paper identifies four income groups: the so-called poor countries, upper middle- and lower middle-income countries, and wealthy countries. The first part of the article analyzes theoretical and applied research in health care, demography, and the relationship of life expectancy with economic development. At the same time, special attention is paid to scientific publications that address the impact on macroeconomic growth in individual countries of such factors as the development of healthcare systems, environmental factors, and life expectancy.

The second part of the article highlights issues of testing empirical hypotheses about the direction of the influence of certain groups of factors on life expectancy and the degree of their influence on different income groups of countries using data from the World Bank and the World Health Organization. The paper uses panel data for 2011–2019, based on which regression models are built for each income group of countries, taking into account time lags to correct for endogeneity.

The results of the study show the importance of both health system characteristics and socioeconomic factors in most income groups. However, it turns out that the influence of individual factors on life expectancy differs depending on the value of GDP per capita of the country. Thus, for poor countries with low life expectancy, the problems of food availability, health care costs, the share of Internet users, unemployment, and population density are significant. At the same time, in middle-income countries, life expectancy is influenced not only by the above factors but also by the proportion of the urban population, the prevalence of tobacco, the number of hospital beds, and carbon dioxide emissions. For wealthy countries, however, bad habits (both the prevalence of tobacco and alcohol consumption) that are commonly called "diseases of civilization", turn out to be especially significant.

Published: February 2023

This research aimed to compare the short and long-term effects of technology-supported and inquiry-based teaching prepared within the scope of energy transformation on students’ academic achievement. It was designed as an exploratory action research case study. The research group consisted of forty-three students studying at the seventh grade (between thirteen-fourteen ages) of a public middle school in Turkey during the fall semester of the 2017 year. One of the classes with a similar academic background in the school where the researcher also worked as a science teacher was assigned as the experimental group and the other as the control group. The activities in the experimental group were carried out in a technology-supported manner using PhET simulations supported by also worksheets, while the control group was taught based on inquiry-based hands-on laboratory activities by worksheets. The data were collected through an achievement test consisting of open-ended questions and scoring with a rubric. The test was implemented twice, after the interventions, and in the following sixth month for both groups. Normally distributed data were compared with interdependent and paired-samples t-tests. The results showed that although the achievement scores for the technology-supported teaching group were significantly higher in the post test, no difference between the scores at the end of the sixth months, and significant information losses were experienced in both groups, with the most technology-supported science teaching.
Exploring the Relationship between Reading Maturity, Reading Strategy Use, and Gender with Reading Comprehension of EFL Undergraduates in Iran
Authors: Sabzehparvar Alireza
Published: February 2023

This research investigated the relationship between reading maturity, reading strategy use, and gender with Iranian EFL undergraduates’ reading comprehension. The results revealed that the most preferred strategies were cognitive in nature. Moreover, the Iranian EFL undergraduates were intellectually enriched by most of what they read and enjoy reading materials that teach them the things that they did not know before. Also, it was found that the most observable effect of gender was on interpreting the text while reading, followed by reading the text again when some parts are difficult to understand. In both of these cognitive strategies, females outperformed the male students in using these two strategies. Furthermore, no correlation was observed between the most applicable reading strategy (b6: I read the text again when some parts are difficult to understand) and reading comprehension. What’s more, there was no correlation between reading maturity and reading comprehension. However, it was proved that there was a significant correlation between gender and reading comprehension. Reading maturity and the most applicable reading comprehension strategy (b6) had no significant correlation with reading comprehension as shown by the multiple regression results while gender revealed such a correlation. There was no significant correlation between the most applicable reading strategy (b6) and reading maturity. Furthermore, there was no relationship between gender and the mentioned reading maturity subgroups (c, d, e, and g) but gender correlated between subgroups f and h. At last, it was found that there was no relationship between gender and the most applicable reading strategy.

Authors: Ghosh Sudipta , Aithal P.S.
Published: February 2023

Investment return may be defined as a recital gauge which is used to compute the effectiveness of an investment. In addition, it helps to assess the competency of dissimilar investments at a dot of occasion. Return on investment is an endeavour to straightforwardly calculate the income of a finicky investment in relative to the outlay of its investment. In this background, the present research paper is an attempt to study the impact of investment returns of coal industry in Indian CPSEs during 2010-11 to 2019-20. Overall, the coal industry has generated positive returns in terms of ROA, ROCE, and ROE. The sub-period analysis reveals that on the average, investment returns in terms of ROA and ROCE have decreased from 1st half to 2nd half, while investment returns in terms of ROE has improved from 1st half to 2nd half of the study. Moreover, all the investment ratios (except ROCE in the 2nd half) show relatively stable performance. Furthermore, 1st half shows better consistency in ROA and ROCE as compared to that in the 2nd half, while ROE marginally shows better consistency in the 2nd half as compared to that in the 1st half. The noteworthy positive impact in ROE implies that coal industry plays a crucial position in the monetary enlargement of the Indian economy. Hence, the Govt. must take essential steps earn more returns on investment and thus helps in the economic development of the country.

Machine Learning Approach for Early Detection of Alzheimer’s Disease
Authors: Suja G P
Published: February 2023

Alzheimer’s Disease (AD) is thought to be the most generally known cause of dementia, and it is estimated that only one in four people with Alzheimer’s are properly identified. While there is no definitive cure, the negative effects may be ignored while the weakening is mild. Treatment is most effective when it begins before major downstream injury occurs, i.e., at the stage of moderate cognitive impairment (MCI) or much earlier. Physical and neurological examinations and neuropsychological and cognitive testing are used to diagnose Alzheimer’s disease. There is a need for improved diagnostic tools, which is what this postulation addresses. Kaggle is an online open-access dataset for improving the Alzheimer’s disease diagnosis technique. The information acquired during the conference is documented. One goal of this theory’s research is to look at machine learning methodologies to create a classifier that can help screen new persons for different stages of Alzheimer’s disease. In comparison to previous work methods, our methodology is suitable for breaking down diverse classes in a single setting and needs less distinct training samples and inconsequential prior knowledge. In our tests, we saw a significant improvement in categorizing all diagnostic categories. Initially, the model is trained on 64 evaluated examples from the Kaggle database. We next test our created model on the whole set of entries supplied by the Kaggle dataset to confirm our framework’s finding. Our results show 96.37% accuracy in AD detection and categorization.

Authors: Pizzi Reynoso Tatiana
Published: February 2023

El trabajo analiza la relación conflictiva entre la actual transición energética global y sus consecuencias para la industria extractiva del litio desde un enfoque integrado de economía y ecología políticas. A partir del caso del Salar de Salinas Grandes y la Laguna de Guayatayoc en el noroeste de Argentina, se identifican las relaciones de poder arraigadas en la actividad económica y en las instituciones locales que perpetúan el eco-colonialismo en la región y la reacción de las comunidades locales indígenas.

La participación de los chalcas en la conquista de México Tenochtitlan, ¿aliados o rebeldes?
Authors: Jalpa Flores Tomás
Published: February 2023

El artículo analiza el papel de los pueblos chalcas durante la conquista española. Centra su atención en los cambios ocurridos durante la segunda mitad del siglo XV a raíz de la conquista del territorio por los integrantes de la Triple Alianza. La derrota se tradujo en una crisis interna que alteró las relaciones entre los diferentes linajes. Esto permite entender los conflictos de intereses entre los distintos sectores de la sociedad y su participación en el conflicto bélico al lado de uno u otro bando.
occisión ritual mesoamericana y la prisión de Cortés
Authors: Serrano Sánchez Carlos , Corona Sánchez Eduardo
Published: February 2023

En diversas fuentes referentes a la Conquista se relata que Cortés fue hecho prisionero: en Chalco, cuando estaba amagando la cuenca de México para cercar a los mexica en Tenochtitlan, y posteriormente en Tlatelolco, durante el sitio que conllevó a la destrucción de ambas ciudades. Y aunque se destaca que escapó con la ayuda de sus propios soldados o por el auxilio de sus aliados acolhuas, no se explica por qué no lo mataron en ese momento. Si eso hubiera sucedido, ello habría tenido trascendencia en la respuesta de los pueblos mesoamericanos ante la invasión mercantil hispana, y de algún modo habría cambiado el curso de la historia.

Al respecto, consideramos que ese hecho tiene que ver con la visión cosmogónica mesoamericana en relación al papel de la occisión humana y el sacrificio propiciatorio del corazón que realizaban los guerreros con sus cautivos; de ello tenemos referencia en las fuentes etnohistóricas, que puede contrastarse con datos de la antropología física, tal como se muestra en restos óseos que evidencian la occisión ritual y el tratamiento post sacrificial del cuerpo del cautivo. Lo cual indica el propósito de los guerreros mexica, de capturar a Cortés para conducirlo a la piedra de sacrificios del templo de Huitzilopochtli o de Tezcatlipoca.
A mentalidade renascentista e a tipografia tardia no Brasil
Authors: Escobar Bolívar Teston de , Heemann Adriano
Published: February 2023

O atraso da chegada da tecnologia tipográfica, no Brasil, é um tema frequentemente abordado, sobretudo em pesquisas da área da história da imprensa e da história do livro. O presente artigo traz uma revisão bibliográfica da literatura consolidada sobre o assunto, analisando suas contribuições sob a óptica das ciências da tecnologia e sociedade (CTS). O resultado é uma explicitação da mentalidade renascentista que estava em curso na Europa durante o período inicial da colonização do Brasil e, consequentemente, os efeitos que tal mentalidade traz para a compreensão da tipografia enquanto elemento de um sistema sociotécnico, do qual decorre não apenas um aumento na produção de livros, mas também novas compreensões em relação à autoridade sobre a palavra escrita
Vilém Flusser e o design da fotografia
Authors: Shimoda Flávio , Oliveira Mirtes Marins de
Published: February 2023

O artigo apresenta o percurso de uma pesquisa que problematizou a fotografia a partir do campo do design. Para caracterizar o significado conceitual da expressão ‘design da fotografia’, a pesquisa delimitou a obra do pensador Vilém Flusser como o seu objeto de estudo. Partindo de uma pesquisa bibliográfica realizada junto ao Arquivo Vilém Flusser São Paulo, o trabalho procurou localizar e mapear as temáticas do design e da fotografia na cronologia e no conjunto dos textos da obra de Vilém Flusser, para rever e rearticular as interpretações dos seus significados e dos seus processos filosóficos de conceituação do design e da fotografia, estabelecendo assim uma interlocução que resultou em um entendimento do design da fotografia como uma linha de pesquisa do campo do design, que se propõe a estudar a fotografia enquanto projeto do aparelho e produto de um contexto cultural.
Percepção de usabilidade de dispositivos assistivos auxiliares de mobilidade na infância: uma contribuição para o design
Authors: Lourenço Gerusa Ferreira , Paschoarell Luis Carlos
Published: February 2023

O avanço da Tecnologia Assistiva tem incrementado o interesse do design na interação entre usuários, terapeutas e dispositivos. Aspectos referentes à eficácia, eficiência e satisfação têm sido alvo de estudos, porém, quando este usuário é uma criança ou adolescente, as experiências sofrem influências das percepções de seus cuidadores e profissionais atuantes. O presente estudo objetivou investigar a percepção de usabilidade de dispositivos assistivos auxiliares de mobilidade, na perspectiva dos usuários (crianças e suas mães) e terapeutas. Com metodologia qualitativa, aplicou-se o Critério Brasil, o B-QUEST 2.0, a versão preliminar do Children’s PIADS e entrevistas com três crianças e suas mães; e duas fisioterapeutas e uma terapeuta ocupacional que as acompanham em um centro de reabilitação. Os resultados indicam que o ganho em funcionalidade e a frequência de uso são métricas de usabilidade para os terapeutas, e fatores físicos (dimensões, peso e cor), além de conforto e segurança, são as métricas de interesse dos usuários (mães e crianças). Tais resultados expõem os fatores da usabilidade de dispositivos assistivos destinados à mobilidade do público infantil.
Desenvolvimento e aplicação de um modelo de Data-driven Design para fomentar o comportamento sustentável
Authors: Fialkowsk Valkiria Pedri , Santos Aguinaldo dos
Published: February 2023

A inteligência com base em Big Data tem ganhado destaque ao possibilitar a rápida obtenção de informações acerca do comportamento do usuário, facilitando a tomada de decisões em design. Por conseguinte, este artigo, derivado de uma tese, tem como objetivo o desenvolvimento e aplicação de um modelo de apoio ao processo de design estratégico para desenvolver metacenários que visam o comportamento sustentável, orientado por dados de Big Data. O trabalho aqui relatado, de abordagem qualitativa, foi estruturado de acordo com o método Design Science Research, dividido em 3 principais momentos: compreensão do problema (para a proposição do artefato), aplicação do artefato (para desenvolvimento do mesmo) e resultados (avaliação e aprendizagem). A compreensão do problema deu-se com revisão de literatura e estudo de caso ex-post facto, resultando na versão preliminar do modelo. Este, então, foi aplicado em um contexto prático empresarial. Os resultados apontam oportunidades de pesquisa para o uso do Big Data no design de soluções sustentáveis, bem como são indicados aspectos para refinamento do modelo proposto.
