Objetivo: Avaliar o equilíbrio, a marcha e as atividades instrumentais da vida diária de idosos com e sem neuropatia diabética. Metodologia: Realizou-se um estudo transversal com usuários do SUS, residentes em João Pessoa. A amostra foi constituída por 44 usuários, selecionados por acessibilidade, com a idade variando de 60 a ≥ 71 anos. Os participantes foram alocados em dois grupos: GC – diabéticos sem neuropatia (n= 22) e GN - diabéticos com neuropatia (n= 22). A análise dos dados foi realizada por meio de estatística descritiva e inferencial. O teste t de Student foi empregado para verificar a igualdade entre as médias das variáveis. O Teste de Pearson foi utilizado para investigar a correlação entre as variáveis. O nível de significância utilizado foi de 5%. Resultados: Em relação à escolaridade, 41,0% dos integrantes do GC e 55,0% dos participantes do GN concluíram o ensino fundamental (p ˂ 0,001). 68,0% e 81,0% dos indivíduos, respectivamente, do GC e do GN possuíam uma renda per capita entre 1,3 a 2,5 salários mínimos (p ˂ 0,001). A associação do diabetes com a hipertensão arterial esteve presente em ambos os grupos, acometendo 64,0% do GC e 73,0% do GN (p ˂ 0,001). Pela Escala de Tinetti a média dos escores dos grupos foi 10,53 para o GC e 7,27 para o GN (p ˂ 0,001). No GN identificou-se uma correlação com o início da marcha, o comprimento e a continuidade do passo e a base de apoio (p < 0,05). Utilizando-se a Escala de Berg verificou-se que a média dos escores dos participantes do GC (48,86) foi maior que a dos usuários do GN (40,05) (p ˂ 0,001), evidenciando um déficit de equilíbrio nos participantes do GN, aumentando o risco de quedas. De acordo com a Escala de Lawton verificou-se uma diferença entre as médias dos grupos GC (17,56) e GN (16,22) (p ˂ 0,001), evidenciando que os participantes de ambos os grupos apresentaram um comprometimento para desempenhar as atividades instrumentais da vida diária - AIVDs. Conclusão: As alterações mais relevantes foram encontradas nos integrantes do GN no que concerne ao equilíbrio, às AIVDs e à marcha, como também nos episódios de quedas.

Medicina Legal, vida e infanticídio no México (1860-1870)
Authors: Pereira da Silva Julio Cesar
Published: August 2021

Examinam-se neste artigo as concepções sobre vida e infanticídio do médico mexicano Luis Hidalgo y Carpio, bem como seus debates e estratégias para tentar estandardizá-las entre os médicos e juristas, nas décadas de 1860 e 1870. Para isso, analisam-se seus textos publicados na Gaceta Médica de Méxicoe dois manuais de Medicina Legal de sua autoria. Demonstra-se, com isso, em quais termos se deram alguns debates, estratégias e negociações científicas acerca de elementos fundamentais à organização do Estado-nacional mexicano. Na virada das décadas de 1860 e 1870, os trabalhos das duas comissões incumbidas de elaborar novos códigos legais para o México (Penal e Civil) foram retomados. Nisso, Hidalgo y Carpio, então membro da Academia Nacional de Medicinae professor de Medicina Legal da Escuela Nacional de Medicina, foi convidado a sejuntar à comissão de elaboração do Código Penal, composta majoritariamente por juristas. Entre outras atribuições, a comissão teve que estabelecer uma série de definições para alguns delitos. Entre eles, estavam os de aborto e infanticídio. O problema, todavia, era que as definições desses crimes estavam diretamente relacionadas à categoria de vida, a qual, por sua vez, era controversa até mesmo entre os membros da Academia. Sem um consenso de quando e como a vida se iniciava, nem o tempo e as condições para se considerar o feto uma criança recém-nascida, tornava-se difícil categorizar e atribuir penalizações aos atentados contra ela. A determinação da existência da vida também era elementar à definição de outros artigos do Código Civil relacionados à herança e aos direitos do nascituro e do recém-nascido. Todas as discussões sobre vida e infanticídio têm como pano de fundo um cenário carregado de sentimentos antifrancês e anticlerical, aguçados no México com a Restauração Republicana, em 1867.
Doutor Feliciano André Gomes [1859-1927]
Authors: Silva José Bento Rosa da , De Souza Arthur Danillo Castelo Branco
Published: August 2021

Muito se tem discutido sobre a atuação da população negra no movimento abolicionista brasileiro e no imediato pós-abolição. Descobriu-se que, apesar de todas as limitações impostas pelo sistema escravista e pelo racismo estrutural, a população negra esteve em evidência e transformou a realidade a partir de suas experiências mutualistas, fazendo uso de suas redes de proteção. Feliciano André Gomes, um dos filhos do africano livre Feliciano André Gomes da Costa, foi um homem negro que conseguiu, através do associativismo, dos estudos e da militância política, ascender política e socialmente. Entre o fim da escravidão (1888) e a Primeira República (1889-1930) conseguimos acompanhar a trajetória desse líder político e intelectual negro e suas atuações tanto no movimento abolicionista, quanto no movimento operário e intelectual em Pernambuco. Feliciano André Gomes foi um dos muitos homens negros que impuseram à sociedade o reconhecimento de suas habilidades, contradizendo as teorias raciais em voga. Veremos que, ao mesmo tempo em que Feliciano André Gomes fazia parte de uma “elite negra”, também representava categorias como escravizados e artífices, posteriormente chamados de operários ou “trabalhadores nacionais”, fazendo-se um líder das camadas populares. A nossa iniciativa, longe de querer esgotar o debate sobre a participação política da população negra entre a abolição e a primeira república, é a de acender uma tocha, através da vida de André Gomes, para que possamos desconstruiras imagens de anomia e de “bestialização”, que, durante muito tempo, recaiu sobre a população negra brasileira.
transformação dos índios aldeados em índios vilados
Authors: Antunes Ticiana de Oliveira
Published: August 2021

A história da ocupação e domínio do território cearense é de muita violência contra os povos nativos. Para sobreviverem, os índios desenvolveram uma série de ações, negociando, lutando, adaptando e reelaborando suas visões e realidades, acumulando experiência e cultura política, que foi essencial para a manutenção de sua identidade e das suas terras coletivas. O Diretório Pombalino teve uma grande longevidade no Ceará e, mesmo com a sua revogação oficial, permaneceu como modelo na condução e no trato da população indígena até meados do século XIX (SILVA, 2005). Este artigo de revisão bibliográfica tem por objetivo demonstrar como a historiografia cearense sobre o período apresenta diversas estratégias dos povos indígenas para a manutenção de suas terras e interesses. A partir dessas leituras, e com o entrecruzamento de fontes apresentadas pelos autores, é possível compreender como os indígenas responderam a essa realidade. Este texto destaca os movimentos de circulação e deslocamento dos índios pelo território cearense, como forma de resistência em busca de melhores condições materiais, acionando redes de apoio e multifacetando suas identidades em prol de seus interesses.
Rupturas e permanências nas povoações indígenas da Bahia
Authors: Santos Fabricio Lyrio
Published: August 2021

O artigo discute a recepção e a implantação do Diretório dos Índios na antiga capitania da Bahia buscando evidenciar as adaptações promovidas pelas autoridades locais tendo em conta as dinâmicas políticas envolvidas e os diferentes interesses em jogo. Redigido em 1757 e aprovado em 17 de agosto do ano seguinte, o Diretório visava regular o funcionamento das vilas e povoações indígenas criadas no contexto do reformismo ilustrado pombalino a partir da extinção dos aldeamentos missionários, notadamente aqueles administrados pelos jesuítas, e tendo como princípio básico a ideia de “civilizar” os índios. Apesar de seu caráter de política oficial, o Diretório terminou por não ser integralmente aplicado na Bahia, o que não impediu que provocasse importantes rupturas no funcionamento e na dinâmica interna das povoações indígenas, divididas em vilas, missões e aldeias, assim como no protagonismo de seus moradores. Por outro lado, sua adaptação ao contexto local ocasionou também outras tantas permanências em relação à situação histórica anterior baseada na jurisdição civil e religiosa dos missionários sobre aquelas populações.

Semanas después del inicio de los síntomas y evolución estable presenta insuficiencia renal aguda que requirió terapia de reemplazo renal. Se descartaron otras patologías subyacentes de índole autoinmune. Hubo recuperación de azoados y normalización de los demás paraclínicos el día 40 de la enfermedad.  El paciente continúa asintomático, 4 meses después, con tratamiento con esteroide oral, en descenso lento y gradual. Se debe considerar la evaluación permanente de las pruebas de función renal en los pacientes que presenten Síndrome de DRESS, por su asociación con Nefritis intersticial aguda y complicaciones relacionadas.
Vegetation cover effects on sediment concentration and overland flow under artificial rainfall intensity
Authors: Boussaadi Mounia , Mouzai Liatim
Published: August 2021

Soil erosion depends on a number of factors including rainfall intensity,
density of plant cover, and area cover. The objective of this study is to
investigate the impact of these factors on flow velocity, overland flow
regimes, sediment concentration, and absolute soil detachment. The soil used
in this study was sandy remolded agricultural soil. The soil is packed in a
tray of 1 m2 fixed on a slope of 3%; five different intensities were
simulated under different vegetation cover (density and area). The results
indicated that the overland flow velocity with vegetation cover was best
described by polynomial function. The mean flow velocity varied from 0.021
to 1.244 m/s. Overland flow regime is subcritical and laminar. However,
there are significant relationships between the vegetation cover density and
sediment concentration and absolute soil detachment. The sediment
concentration ranged from 1.38 to 5.65 kg/m3 whereas the absolute soil
detachment ranged from 0.021?10-3 to 1.244?10-3 kg/m2/s. Finally, the
vegetation cover presented a good protector to soil sediment from erosion.
The impact of interest groups on government size-regional evidence from Turkey
Authors: Sağdıç Ersin , Gümüş Öner , Tuncer Güner
Published: August 2021

This study is aimed to investigate the regional pressure groups' effect on
the government size in Turkey. According to the public choice theory,
elections, political parties, interest and pressure groups, and bureaucracy
significantly affect the public production process. Among these actors,
pressure and interest groups directly affect variables such as economic
growth and public expenditures. In this study, panel data analysis was used
to observe the regional effect. The research data set covered 81 provinces
of Turkey and the period between 2006 and 2018. According to the results, it
was found that interest and pressure groups increase the public expenditures
in the less developed regions in Turkey. These results are consistent with
the empirical and theoretical studies. For this reason, the study has an
important contribution to the literature. This study offers significant
conclusions that public economic policies might be under the influence of
interest and pressure groups. Even if stated that the results of this study
might have many economic, demographic, social, and political reasons
regarding Turkey, in the context of public choice theory, it could be seen
as a significant indicator of not using public expenditure policies as
efficient instruments. This situation shows that public resources are not
used efficiently in Turkey and the government has a negative effect on the
economy. To eradicate this negative effect, governments coming to power in
the future ought to produce economic, political, and social policies in
order to decrease the regional differences dramatically in Turkey.
Socio-еconomic transformation of Sumadija district (Serbia)

Published: August 2021

The paper starts from the hypothesis that the examined area is characterized
by a process of intensive functional transformation accompanied by certain
population changes. The transformation of the settlement structure is shown
in the area of Sumadija district. The trend of demographic and economic
development was observed with a historical overview. It was upgraded with
quantitative analyzes (chain index, population change index, functional
classification, index of specialization and localization) for the period
1971-2011. The aim was to determine the degree of socio-economic
transformation of Sumadija district and the regularities according to which
these changes took place. Industrialization generally brings changes in the
functional orientation and redistribution of the population. The
deagrarianization was one of the main features, with parallel emigration of
the rural population. These changes were intensive in 1961-1981, when the
peak of employment in secondary activities was registered. Since then,
significant spatial transformation in Sumadija district was visible. Special
analyzes were used to confirm the assumption that Kragujevac is a dominant
labor center, an administrative and service nucleus, which has a propulsive
influence on the development of its immediate surroundings (suburban belt)
and the wider area (Sumadija district). The contribution of this paper is in
the understanding of the scope, spatial distribution, and intensity of
changes that have occurred in Sumadija district. It introduces the
historical circumstances and quantitative research into a broader concept as
a basis for understanding the trajectories of spatial and socio-economic
development, and responds to many social challenges specific for this
territory.
Tax Non-Audit Services and Client Income Tax Estimation Error
Authors: Choudhary Preeti , Koester Allison , Pawlewicz Robert
Published: August 2021

The provision of non-audit services (NAS) to audit clients can generate knowledge spillovers that enhance auditors' judgments or self-review and self-interest threats that impair auditors' independence. Prior research finds mixed evidence of a relation between tax NAS and clients' (actual and potential) material GAAP violations in accounting for income taxes. As auditors are likely to avoid material GAAP violations, we re-examine this issue using a measure that reflects immaterial or within-GAAP estimation error in clients' income tax expense. We find that greater amounts of tax NAS are associated with greater income tax estimation error, consistent with tax NAS threating auditors' independence. The association is partially offset by auditor expertise and concentrated in engagements where auditors face both self-review and self-interest threats. Our findings inform the ongoing policy debate regarding whether accounting firms should provide tax NAS to their audit clients.

Game Changer: Can Modifications to Audit Firm Communication Improve Auditors' Actions in Response to Heightened Fraud Risk?
Authors: Austin Ashley A. , Carpenter Tina D.
Published: August 2021

Regulators express concern over auditors' failure to respond to fraud risks. Audit firms communicate the importance of remaining skeptical and alert for fraud, but busy auditors give these messages insufficient attention. Building on psychology theory, we develop an innovative intervention designed to improve audit firm communication by incorporating game-like elements. We expect game-like elements to pique auditors' interest, deepen their cognitive processing, and enhance their awareness of important fraud concepts, making them more alert for fraud. We experimentally demonstrate that the intervention improves auditors' awareness of important fraud concepts, and these benefits persist to improve auditors' fraud detection actions. Importantly, auditors receiving communication that simulates current practice fail to respond to heightened fraud risk, confirming regulators' concerns. In additional analyses, a model supports our intervention promoting deeper processing of the communication, enabling auditors' subsequent recognition of heightened fraud risk and effective actions. Thus, our results contribute to theory and practice.
On Controlling for Misstatement Risk
Authors: Moon James R. , Shipman Jonathan E. , Swanquist Quinn T. , Whited Robert L.
Published: August 2021

Ex ante misstatement risk confounds most settings relying on misstatements as a measure of audit quality, but researchers continue to debate how to effectively control for this construct. In this study, we consider a recent approach that involves controlling for prior period misstatements (“Lagged Misstatements”). Using a controlled simulation and a basic archival analysis, we show that a lagged misstatement control can significantly bias coefficient estimates. We demonstrate this bias using audit fees as a variable of interest but also show the same issue manifests for other measures that respond to the restatement of misstated financial statements (i.e., internal control material weaknesses and auditor changes). We conclude by discussing alternative approaches for controlling for ex ante misstatement risk and providing guidance for future research.

Published: August 2021

O-GlcNAc transferase (OGT), a nutrient sensor sensitive to glucose flux, is highly expressed in the pancreas. However, the role of OGT in the mitochondria of β-cells is unexplored. In this study, we identified the role of OGT in mitochondrial function in β-cells. Constitutive deletion of OGT (βOGTKO) or inducible ablation in mature β-cells (iβOGTKO) causes distinct effects on mitochondrial morphology and function. Islets from βOGTKO, but not iβOGTKO, mice display swollen mitochondria, reduced glucose-stimulated oxygen consumption rate, ATP production, and glycolysis. Alleviating endoplasmic reticulum stress by genetic deletion of Chop did not rescue the mitochondrial dysfunction in βOGTKO mice. We identified altered islet proteome between βOGTKO and iβOGTKO mice. Pancreatic and duodenal homeobox 1 (Pdx1) was reduced in in βOGTKO islets. Pdx1 overexpression increased insulin content and improved mitochondrial morphology and function in βOGTKO islets. These data underscore the essential role of OGT in regulating β-cell mitochondrial morphology and bioenergetics. In conclusion, OGT couples nutrient signal and mitochondrial function to promote normal β-cell physiology.

Un cariotipo de Adenoscolex oreini Fotedar, 1958 (Capingentidae), un parásito céstodo de carpas, Kashir Gaad, Schizothorax niger (Cypriniformes) ha sido estudiado por primera vez. Consiste en un conjunto de cromosomas de 20 pares de cromosomas metacéntricos, submetacéntricos y acrocéntricos (2n = 20; n = 8m+1sm+1a). Todos los pares son pequeños, miden 1,86-7,22 μm. Parece que el número de cromosomas de A. oreini es mayor en comparación con la de los miembros de la familia Caryophyllaeidae. La variación en el tamaño de los más pequeños bivalentes y otros bivalentes indican que los cromosomas somáticos mostrarán una marcada variación en la longitud del cromosoma más largo y más corto en A. oreini. Hasta ahora nadie ha emprendido los estudios citológicos de este parásito y en la presente investigación se está divulgando su número cromosómico por primera vez.

Published: August 2021

El presente estudio reporta la presencia del parásito dactylogirido Heteropriapulus heterotylus en las branquias de peces invasivos Pterygoplichthys pardalis y P. disjunctivus en ecosistemas de agua dulce del sureste de México. Este studio representa un nuevo registro de hospederos para este parásito y un nuevo registro geográfico de parasitos en P. disjunctivusy P. pardalis. Además, se examinaron los aspectos ecológicos de la prevalencia, abundancia media e intensidad media de H. heterotylus a través de un ciclo anual. Se recolectaron un total de 223 peces, incluyendo 94 de P. disjunctivus y 129 de P. pardalis. Se encontró un total de 148 (66.3%) peces que estaban infectados con este monogeneo, 79 de P. pardalis y 69 de P. disjunctivus. H. heterotylus se registró exclusivamente en los arcos branquiales en ambos peces. En ambos peces la abundancia media de este parasito mostró cambios significativos a través del año. Asimismo, la prevalencia e intensidad media mostraron valores similares en ambos hospederos. El presente estudio demuestra que los estudios parasitológicos en peces exóticos o no nativos pueden ser útiles en el diseño de estrategias de control para la importación de estos peces y deben ser considerados como necesarios antes de fomentar el consumo de peces como una estrategia de control en las regiones donde estos peces invasores proliferan en exceso.

Los estudios sobre nematodes parásitos de reptiles en Argentina son escasos. Aproximadamente 158 especies de Liolaemus (Wiegmann, 1834) han sido mencionadas para Argentina. Sin embargo, 15 especies han sido indicados con algún estudio parasitológico. Debido al escaso conocimiento parasitológico en reptiles de Argentina, se estudiaron los contenidos gastrointestinales de dos especies de lagartijas; Liolaemus parvus (Quinteros, Abdala, Díaz Gómez, & Scrocchi, 2008) y Liolaemus ruibali (Donoso- Barros, 1961). Se determinaron nemátodes hembras Parapharyngodon sp. (Chatterji, 1933) localizados en la región del estómago. Mencionamos los primeros registros de este parásito en estas lagartijas para la localidad de la Reserva de Don Carmelo, departamento de Ullum, provincia de San Juan. Realizamos una importante contribución al conocimiento parasitario para lagartijas del género Liolaemus en Argentina.
Intra-state water conflicts (second half of the XX- early XXI centuries): historical and geographic overview

Published: August 2021

The article reveals and systematizes the main types of conflicts over drinking water, which broke out in the world during the late XX and early XXI centuries. For each type of conflict, a specific example is given and briefly disclosed its history, the main reasons for its deployment are analyzed. It is noted that the overwhelming majority of past and present conflicts are local and take place within national states. But with population growth, industrialization and urbanization, the demand for water is only growing, which leads to increased competition for it and can provoke new disputes over this resource. Separately, the conflict over access to hydro-resources on the Russian-occupied Crimean Peninsula is highlighted.  The experience of studying conflicts over water demonstrates that even local disputes over hydro resources often result in human casualties, worsen people's living conditions, and carry health risks, in particular famine and epidemics.

In the process of harvesting sugarcane at a sugar factory, the Sugarcane Harvester is a tractor used to harvest sugarcane equipped with a slicer knife. Nowadays slicers are still imported from abroad, and the availability is scarce and the price is still expensive. One of the efforts to find an alternative to the slicer is to use leaf springs by hardening the metal through a heat-treatment process. Namely the process of heating steel to temperatures above the critical area followed by rapid cooling called quenching. The purpose of this study was to determine the effect of holding time and the effect of cooling media on the hardness and impact strength of leaf springs and to determine the ideal holding time and the most optimal cooling media to increase the hardness and impact strength of leaf springs. As for the research method, the spring leaves were heat-treated with a temperature of 8500 C for 30 minutes and 60 minutes and then cooled using oil, saltwater, and water as media. The method used is observation, literature study, testing, and documentation.

The results obtained from this study were at a temperature of 8500 C with a holding time of 30 minutes the best hardness value was 477 VHN and 0.42% increase, the best impact strength value was 0.03433 J / mm2 and 87.71% decrease, and the two cooling media, namely oil. At a temperature of 8500C with a holding time of 60 minutes the best hardness value was 534 VHN and 12.42% increase, the best value of impact strength was 0.03203 J / mm2 and 88.53% decrease, and the two cooling media were oil as well. So that oil is the most optimal medium for changing the mechanical properties of the Sugarcane Harvester slicer because the oil can carry a carbon layer from the cooling process that takes place and the cooling rate of the oil is not too fast from the cooling media of brine and water because of its viscosity.

Rice quaker are traditional food from the Sambas regency. The manufacture of rice quaker has been traditionally done by pounding it. Economically, the production capacity of traditionally made rice quaker is so low that it needs to be increased by changing the manual to mechanical flattening system. The purpose of this research is designing a prototype machine for flattening rice quaker as well as conducting experimental studies on the flattening process. The research stages were to design, manufacture, and test the performance of the flattening rice quaker. The independent variables of the study were the gap width and the number of flattening, while the dependent variables of the study were thickness and percentage damage of rice quaker. The width of the gap was varied into 0.4 mm, 0.6 mm, 0.8 mm, and 1.0 mm, while the number of flattening was varied to 1, 2, and 3 times the flattening. The result of the construction of the prototype rice quaker machine is in accordance with the initial design, and can work to flatten rice quaker. The engine test was carried out at a flat roller speed of 360 rpm. The thickness of the rice quaker made traditionally, 0.98 mm, can be approached by flattening using a machine at a gap width of 0.8 mm with 2 flakes resulting in a thickness of 0.96 mm quaker with a percentage of damage of 38.52%. In general, the level of damage to the resulting rice quaker is still very high, so further analysis is needed.Keywords: Rice quaker, gap width, flattening machine, flat rollers.

Coal is still widely used as the main fuel in the industry, especially the power generation industry (PLTU), cement plants and etc. Coal is a fossil fuel whose availability is thinning and its fires produce CO2 emissions that cause a rise in greenhouse gas (GHG) concentricity. On the other biomass is an alternative energy source that is abundant, including empty bunches of oil palm (TKKS), but has poor combustion properties compared to coal when burned directly. The properties of biomass burning can be improved by certain treatment, one of which is through the process of torrefaction. Biomass torrefaction has a calorific value equivalent to sub-bituminous coal B, so it has the potential to be used as an alternative fuel for coal. The purpose of this study was to determine the maximum temperature that occurs in the burner. In this study co-combustion was conducted on simulation of ANSYS program with powder system (pulverized combustion) because this type in recent decades is widely used in industry. In this study conducted a simulation on ANSYS to determine the temperature on the burner and the concentration of emissions produced. The results showed that the simulation of co-combustion burner burner showed the maximum temperature reached 970°C.  The effect of burner and burner temperature in the form of swirl provides sufficient oxygen with more perfect combustion resulting in decreased concentration of CO2 emissions and low concentration of N2 due to higher nozzle temperature. High temperatures lower the concentration of SO2 in the burn chamber.Keyword: Co-combustion, pulverized co-combustion simulation, TKKS torrefaction, burner.

EMS is a control system on the engine to regulate the proper mixing of air and fuel, accurate ignition timing, and control of other systems on the engine, according to the conditions and workload of the vehicle. The EMS component consists of sensors, ECU, and actuator. Engine control is fully regulated by the ECU. After getting data from the sensor, the ECU sensor will signal the actuator to control the engine, so that the work of the engine can be controlled according to the conditions of the engine. The effect of the cooling water temperature sensor is very large at stationary (Idle Speed Control/ISC). This research method is carried out by varying the temperature of cooling water (Engine Coolant Temperature/ECT) to get the mass of gasoline, air mass, air fuel ratio, engine speed, ignition angle, and gasoline consumption at each ISC load. The results of the research and data processing show that gasoline consumption will decrease every time the cooling water temperature increases. The AC (Air Conditioner) load ranges from 1,123 x 10-2 to 2,164 x 10-2 kg/hour, the power steering load ranges from 6,311 x 10-3 to 9,482 x 10-3 kg/hour, the electrical load ranges from 6,608 x 10-3 to 7,876 x 10-3 kg/hour and without load ranges from 6,024 x 10-3 to 7,920 x 10-3kg/hour. From these data it can be concluded that the effect of the ECT sensor is very large on engine performance at stationary rotation (ISC).Keywords: Sensor, ECU, Actuator.

It presents an experimental framework forexploring real-time collaboration in Digital Content Creation such as animation. The framework combines a push-pull network architecture and data translation protocol with hybrid command/data replication mechanisms. Thisenables the synchronization of object components and hierarchy between multiple instances of the same DigitalContent Creation application in a non-destructive way. Conflicts between users are prevented with a strong rightmanagement system. We demonstrate the interest of such an approach by means of an application example inBlender and discuss collaborative experimental sessions outcomes over a Local Area Network and through theInternet.
Model-based tracking on conveyor belts: Evaluation and practical results in the automotive industry
Authors: Scheer Fabian , Loos Moritz , Neumann Markus
Published: August 2021

Model based tracking (MBT) of painted cars in the automotive mass production on conveyor belts with robots is a challenging task. Manydisturbing sources that have an impact on the MBTexist, like the influence of the localized work illumination, the synchronization of the MBTto the conveyor belt, reflections in the paint, variants of the cars and the complexity of the used CAD models. By having such complex systems the mere assessment of the accuracy and stability of MBT approaches by literature can be hard. A real world application is necessary for a better understanding. Therefore, we present the evaluation of MBT for a robotic gap measurement system onpainted cars. The influence of local lighting and car paint is analysed in detail regarding the MBT accuracy. To reduce complexity considering the car variants on a production line,we evaluated the MBT with different model setups and show the influence on the MBTresults. Regarding MBT in a complex calibrated system that runs twenty-four-seven, a broken or slightly displaced camera should not have a huge impact like a loss of production. For this reason,we present a method to exchange a camera within minutes andwithout a loss of the overall accuracy. The method relies on a separate test specimen and isevaluated in detail. The presented evaluations can help researchers and the industry to better understand and assess the influence and correlations of different error sources or disturbing factors for the usage of MBT in complex conveyor belt based robotic applications.

Published: August 2021

This paper summarizes the research on the influence of HEVC(High Efficiency Video Coding)configuration on immersive video coding. The research was focused on the newest MPEG standard for immersive video compression –MIV (MPEG Immersive Video). The MIV standard is used as a preprocessing step before the typical video compression thus is agnostic to the video codec. Uncommon characteristics of videos produced by MIV causes, that the typical configuration of the video encoder (optimized for compression of natural sequences) is not optimal for such content. The experimental results prove, that the performance of video compression for immersive video can be significantly increased when selected coding tools are being used.
