description: The presence of hyperreflective foci (HFs) is related to retinal disease progression, and the quantity has proven to be a prognostic factor of visual and anatomical outcome in various retinal diseases. However, lack of efficient quantitative tools for evaluating the HFs has deprived ophthalmologist of assessing the volume of HFs. For this reason, we propose an automated quantification algorithm to segment and quantify HFs in spectral domain optical coherence tomography (SD-OCT). The proposed algorithm consists of two parallel processes namely: region of interest (ROI) generation and HFs estimation. To generate the ROI, we use morphological reconstruction to obtain the reconstructed image and histogram constructed for data distributions and clustering. In parallel, we estimate the HFs by extracting the extremal regions from the connected regions obtained from a component tree. Finally, both the ROI and the HFs estimation process are merged to obtain the segmented HFs. The proposed algorithm was tested on 40 3D SD-OCT volumes from 40 patients diagnosed with non-proliferative diabetic retinopathy (NPDR), proliferative diabetic retinopathy (PDR), and diabetic macular edema (DME). The average dice similarity coefficient (DSC) and correlation coefficient (r) are 69.70%, 0.99 for NPDR, 70.31%, 0.99 for PDR, and 71.30%, 0.99 for DME, respectively. The proposed algorithm can provide ophthalmologist with good HFs quantitative information, such as volume, size, and location of the HFs.

description: Résumé : Ces dernières années, le tarissement des sources fossiles et les soucis économiques et environnementaux liés à leurs exploitations ont fait naitre chez les décideurs et les producteurs d’énergie électrique, un grand intérêt pour l’interconnexion des générateurs d’énergies renouvelables aux réseaux électriques, particulièrement le photovoltaïque (PV). Une mauvaise planification ou une mauvaise localisation, à grande échelle de ces sources d’énergies renouvelables, surtout intermittentes, peut pourtant affecter négativement les performances des réseaux auxquels elles sont destinées. Cet article analyse les impacts d’une injection à grande échelle des énergies PV sur la stabilité des réseaux électriques. Les résultats d’une connexion des PV au réseau IEEE (Institute of Electric and Electronique Engineering) de 9 Jeux De Barres (JDB) sont présentés et analysés pour démontrer ces possibles impacts négatifs des Productions PV sur les réseaux. Les résultats de l’analyse du régime permanent révèlent qu’une pénétration accrue des PV peut conduire à une modification des modules des tensions aux JDB, et à une modification, voir une inversion des transits de puissances sur les lignes. L’étude dynamique révèle qu’une grande pénétration PV conduit à une diminution du temps critique d’élimination des défauts et une perte de synchronisme. Mots clés : Réseaux électriques, Générateurs Photovoltaïques, Stabilité en régime permanent, Stabilité transitoire, injection à grande échelle. Abstract: The rapid depletion of fossil-fuel resources on a world basis and the economic and environmental concerns over electrical energy derived from these sources, have made governments and utilities more interested in connecting renewable alternative sources, such as solar energy, to power systems. If not well sized or allocated, these energy sources will adversely affect the performances of power systems. This paper investigates the impacts of increased penetration of photovoltaic (PV) generation on static performance as well as transient stability of power systems. PV generation systems are added to the IEEE-9 bus test system to replace a portion of conventional generation resources. The obtained simulation results effectively identify the detrimental impacts of increased PV penetration for both steady state stability and transient stability performance. Keywords: Power systems, photovoltaic generators, steady state stability, transient stability, large scale injection.

description: Most physics lovers asked themselves several times: Why should we limit the velocities in our nature to the velocity of light C ? And why a particle of light shouldn't have an ordinary mass even if the redshift or blueshift of light have been discovered.In my previous work about the michelson morley experiment, I concluded that the light can be studied easily like all the other waves. Actually, many scientists venerated the light by some theories that gave a limit to the velocities of photons and abolished their mass.This work makes a conclusion about Einstein’s relativity after an easy study about the Pound-Rebka experiment which deals with the Gravitational effect of light, and you will find also some logical remarks about the Doppler effect.

description: This study aims to design a continuous stirred tank reactor (CSTR) type reactor used in the production of zinc oxide (ZnO) nanoparticles. Mass balance calculations were carried out in this study as a benchmark to find out whether the reactor was working properly by knowing the flow of incoming raw materials and the products produced by the reactor. Furthermore, the design of the reactor and the design of the stirrer used in the reactor is calculated manually using Microsoft Excel. Based on the calculation results of the reactor design, the reactor volume is 8224.359 liters, with a vessel diameter of 73.298 in, a cylinder height of 166.090 in and a cylinder thickness of 73.444 in. The top cover of the reactor measures 12.387 inches with a thickness of 0.072 inches while the bottom cover measures 21.185 inches with a thickness of 0.083 inches. So that the overall height of the reactor is 37.552 in. The reactor is equipped with 1 stirrer with an impeller diameter of 36.722 in, impeller height from the bottom of the tank is 24.433 in, impeller width is 7.344 in and impeller length is 9.180 in. Turbulent stirring flow conditions with a standard motor power for the stirrer is 6.849 HP. It is hoped that this design will serve as a reference for building more economical, more efficient and highly demanding reactors.

description: This study aims to develop and analyze the design of glycerol-water-based heat exchangers (HE) for the production of SiO2 nanoparticles. The shell and tube types are designed in a simple manner with a tube length specification of 5.4864 m, an inner pipe diameter of 0.0165 m, and a shell diameter of 0.9906 m. Then, calculations were performed using Microsoft Excel. The results show that the shell and tube HE design has a laminar flow type with an effectiveness of 22.22% and an impurity factor of 0.0021 °C.m2/W. With reference to the TEMA standard, the shell and tube type HE with the laminar flow does not meet the standards, both in terms of effectiveness and impurity factor. Even though this HE design does not comply with the criteria and standards specified in the application industry, the analysis in this study can be used as education for process design, operating mechanisms, and HE performance analysis.

description: Die Autorin der vorliegenden Bachelorarbeit „Pflegende Angehörige betagter Menschen im Fokus“ richtet sich an Professionelle der Sozialen Arbeit und will für das Thema familiäre Pflege und Betreuung sensibilisieren. Hinter diesem Begriff stehen unzählige Angehörige, welche eine betagte Person aus ihrem familiären Umfeld pflegen und betreuen. Damit erbringen sie eine enorme Leistung, worauf wir als Gesellschaft wohl kaum verzichten können und wollen. Umso mehr verwundert dabei die Tatsache, dass die Belastungsfaktoren und negativen Auswirkungen auf die pflegenden Personen immer noch tabuisiert werden, obwohl diese mehrfach ausgewiesen sind. An dieser Stelle drängt sich aus fachlicher Sicht die Frage nach dem Auftrag und dem Potenzial von professionellen Sozialarbeitenden auf. Die Autorin stellt in der vorliegenden Literaturarbeit entlang der Problemstellung fachliche Bezüge zum handlungstheoretischen Bezugsrahmen Sozialer Arbeit her und schafft somit eine Legitimationsbasis für das Handeln Sozialer Arbeit. In einem weiteren Schritt kristallisiert die Autorin verschiedene Methoden und Konzepte von professionellen Sozialarbeitenden heraus und stellt diese den Belastungsfaktoren von Pflegenden gegenüber. Zum Schluss folgt die Erkenntnis, dass die Soziale Arbeit aus individueller, gesellschaftlicher und professionsbasierter Perspektive dazu aufgerufen ist, in Bezug auf pflegende Angehörige Lösungen zur Milderung und Verhinderung sozialer Probleme zu entwickeln, und Sozialarbeitende aufgrund ihrer wissenschaftsbasierten Methoden über vielfältige „Werkzeuge“ verfügen, um auf die Belastungsfaktoren und deren Auswirkungen zu reagieren.

description: The building envelope (walls, floor, windows,roof) is a very important element of the design as it can have a effect on the energy performance of the building, that is comfortable all year round can be achieved with reasonable levels of insulation, reduced thermal bridging, summertime shading features, and ventilation. Depending on the properties of the thermal zone where we are, it is therefore possible to integrate PCM and optimize their parameters in order to favorably dephase the energy consumption peaks and energy consumption and, by the same token, significantly reducing the use of the HC system. Consequently, the integration of this PCM in the envelopes of new buildings or in renovation would contribute to reduce the energy bill in the building sector in Morocco. So the (PCM) represents a sustainable alternative to reduce energy consumption for this a thermal dynamic simulation was realized with TRNSYS 204. Since PCM involves large latent heat at small temperature phase changes, PCM is used for temperature stabilization and for storing heat with large energy densities and capacity the storage in combination with rather small temperature changes. The simulation was carried out for the climate zone of Morocco (Casablanca Nouasseur). The results of the simulation showed that the use of phase change materials in brick walls reduced overheating in the summer period, decreasing the ambient temperature of the indoor air by 3 ° C.

description: Nowadays, electric arc welding is of great importance in the field of standard assembly techniques in construction, especially for steel parts (construction of frames, automobile frames, tanks ...). The welding quality depends on many factors, including the welding operation. Non-destructive testing by radiography consists of implementing investigative techniques making it possible to judge "without destroying the sample", the state of the weld seam, that is to say to check whether there is a possible internal fault. The aim of this work is to check the quality of the weld seam for different thicknesses of parts. Internal defects were also analyzed using radiographic tests on metal samples of different thicknesses. The results obtained showed that, for samples of small thicknesses, the defects are minimal. On the other hand, for samples of large thicknesses, defects are noted and their severity is proportional to the increase in the thickness of the welded parts. The results obtained showed that, for samples of small thicknesses, the defects are minimal. On the other hand, for samples of large thicknesses, there are generally defects as the thickness increases. Keywords: Electric arc welding, Different thicknesses, Welding defects, Radiography.

description: We introduce a conceptually simple and efficient algorithm for seamless parametrization, a key element in constructing quad layouts and texture charts on surfaces. More specifically, we consider the construction of parametrizations with prescribed holonomy signatures i.e., a set of angles at singularities, and rotations along homology loops, preserving which is essential for constructing parametrizations following an input field, as well as for user control of the parametrization structure. Our algorithm performs exceptionally well on a large dataset based on Thingi10k [Zhou and Jacobson 2016], (16156 meshes) as well as on a challenging smaller dataset of [Myles et al. 2014], converging, on average, in 9 iterations. Although the algorithm lacks a formal mathematical guarantee, presented empirical evidence and the connections between convex optimization and closely related algorithms, suggest that a similar formulation can be found for this algorithm in the future.

description: In this article, a model of a rotor with an asymmetric disk is presented in order to represent Campbell's diagrams and instability maps as a function of the rotations of the support which can significantly change the dynamic behavior of the rotor. Critical rotating speeds can also lead to unacceptable levels of vibration. Indeed, the critical speeds are a function of the dynamic rigidity of the rotating systems and the presence of the gyroscopic forces creates a dependence between the rotating speed of rotation and the natural frequencies to such structures (the CAMPBELL diagrams): this implies that the correct determination of the critical speeds is one of the essential elements when sizing such dynamic systems.

The results of the investigation demonstrated that a synergism effective as anti-wear and inhibitor of corrosion between calcium palmitate and petroleum coke. The effects of calcium palmitate (CAP) alone and in conjunction with other minerals dispersed in petroleum coke were investigated. As the results reduce the corrosion rate of steel and it’s wearing. Photographic analysis of steel inhibited steel reveals that it is cleaner than blank steel. X-Ray photoelectron spectroscopy (XPS) analysis confirmed the adsorbed film and its composition. The results show that wear resistance increased by about 80% and anticorrosion performance increased by about 85%. These findings were explored in terms of the CAP's adsorption isotherm at solid-liquid interface. Also, the XPS confirm that the synergistic action of mixed CAP and petroleum coke with highly ash content after flotation processes

description: «Eine grüne Oase?» ist eine qualitative Forschungsarbeit über die Ausgestaltung von Care-Farm-Angeboten für Menschen mit Demenz. Ziel der Autorinnen Regula Leuenberger und Brigitte Hari war es, herauszufinden, wie in der Schweiz solche Care-Farm-Angebote ausgestaltet werden könnten, welchen Nutzen diese für Betroffene und ihre Angehörigen haben und wie die Soziale Arbeit solche Angebote fördern könnte.

In Zukunft wird es aufgrund des demografischen Wandels und der Alterung der Gesellschaft immer mehr Menschen mit Demenz geben. Das Bundesamt für Gesundheit hat in seiner Demenzstrategie 2014-2019 Ziele festgelegt, um die Lebensqualität von Betroffenen zu verbessern. Eines dieser Ziele ist es, genügend bedarfsgerechte Betreuungsangebote zur Verfügung zu stellen. Eine spezifische Angebotsform könnten Care-Farms sein, soziale Landwirtschaftsbetriebe, auf denen Menschen mit Demenz betreut werden. In den Niederlanden gibt es mittlerweile knapp 200 solche Care-Farms, während es in der Schweiz nur eine gibt, den Hof Obergrüt im Kanton Luzern.

Um die Forschung möglichst breit abstützen zu können, wurden sowohl Fachpersonen als auch Angehörige von Menschen mit Demenz, die den Hof Obergrüt kennen, mittels Leitfadeninterviews befragt. Anhand der Ergebnisse und der erarbeiteten Theorie konnten verschiedene Kriterien definiert werden, wie Care-Farm-Angebote ausgestaltet werden sollten, um von Betroffenen optimal genutzt werden zu können. Es zeigte sich, dass die Soziale Arbeit nicht nur bei der Etablierung solcher Care-Farm-Angebote eine zentrale Rolle übernehmen sollte, sondern sich allgemein vermehrt in die Arbeit mit Menschen mit Demenz einbringen und auch die pflegenden Angehörigen unterstützen muss.

description: Cette étude a pour objet la conception du système de direction d’un véhicule automatique de type automobile à trajectoire aléatoire (périodes et angles de rotation aléatoires), imprévisible dans le temps et l’espace. Le besoin a été exprimé par les Forces Armées et de Sécurité du Mali pour la formation des tireurs sur des cibles mobiles à trajectoire imprévisible. Le changement de direction est assuré par un moteur « pas-a-pas » actionnant les deux roues avant. Ce moteur est contrôlé par une carte électronique ARDUINO programmée pour générer des codes aléatoires de changement de direction et de pente de déviation. L’ensemble sera en mouvement entre deux murs parallèles. Le mouvement est rendu encore plus aléatoire par le changement de trajectoire induit automatiquement par le contact aléatoire de l’engin avec les parois des murs. Dans cet article, nous montrons les résultats obtenus par simulation informatique sans tenir compte du terrain et de la carrosserie qui pourront faire l’objet de publications ultérieures

description: In many industrial fields, there is an ever growing market demand for highly profitable engines. This fact encouraged to produce very developed engine parts, namely sophisticated injection systems. Consequently, the electronically enhanced injection systems are becoming very widespread for their high efficiency and cause the mechanical automatic systems to be neglected without enough studies. However, the electronically commanded injection is difficult to maintain because of the risks of short-circuits, and it is also difficult and expensive to repair since its captors are in high pressure and temperature areas. This paper aims to introduce a mathematical study of the basic direct injection operation by proving formulas representing forces, velocities and the energy involved in the injection mechanical mechanism without any electronic or computational complications. This theoretical mathematical modeling is useful for the efficiency experimental studies in order to improve the manufacturing and maintenance of all direct injection systems.

description: Engines are nowadays mandatory for the domestic as for the industrial use. However, they need enough control and maintenance in order to make their usefulness last longer. Some works have been done for this purpose but they all propose mechanisms and methods that consume a big amount of useful energy from the engine and thus stops it from being operational during the control, and thus, these studies can’t allow to test continuously the operation of the used engine. Other works propose thermodynamic experiments that are too expensive and difficult to be done in order to provide the characteristics of engines. However, the equations of real gases can only be approximate and the studied gases can’t be considered ideal gases at the high pressures inside engines. This paper proposes new accurate formulas and methods to detect cylinders problems by allowing a continuous control of each cylinder brake work without consuming any energy from the operating engine. This work proposes also a new mechanism to measure the availability of each cylinder of the studied engine and thus introduces a new method to test the second law efficiency for the engine. This work explains also and proves all the formulas and methods after a modeling of the connecting rod and crankshaft operation. Consequently, this is a very useful work for the simulations of engine experts as for the simple understanding of beginners.

Subjects: BTEX emissions; Industrial activities; Atmospheric pollution; Ambient air.

description: This work focuses on identifying the source of BTEX (Benzene, Toluene, Ethylbenzene, Xylene) emissions generated by hydrocarbon-related industrial activities and evaluation of its impact on ambient air quality according to European Union (EU) regulations during 2019. The spatial distribution of BTEX concentrations suggest that massive emissions are mainly due to the oil refining activity. BTEX concentration levels at the sampling sites show that benzene was more dominant. Considering the level of atmospheric pollution relative to the indicative value (2 µg/m3) recommended by the EU, the ambient air is considered to be quite polluted with benzene content (5.36 µg/m3) produced mainly by emissions from the oil refining industrial complex.

description: Forest degradation, generally defined as a reduction in the delivery of forest ecosystem services, can have long-term impacts on biodiversity, climate, and local livelihoods. The quantification of forest degradation, its dynamics and proximate causes can help prompt early action to mitigate carbon emissions and inform relevant land use policies. The Democratic Republic of the Congo is largely forested with a relatively low deforestation rate, but anthropogenic degradation has been increasing in recent years. We assess the impact of eight independent variables related to land cover, land use, infrastructure, armed conflicts, and accessibility on forest degradation, measured by the Forest Condition (FC) index, a measure of forest degradation based on biomass history and fragmentation that ranges from 0 (completely deforested) to 100 (intact). We employ spatial panel models with fixed effects using regular 25 × 25 km units over five 3-year intervals from 2002 to 2016. The regression results suggest that the presence of swamp ecosystems, low access (defined by high travel time), and forest concessions are associated with lower forest degradation, while built up area, fire frequency, armed conflicts result in greater forest degradation. The impact of neighboring units on FC shows that all variables within the 50 km spatial neighborhood have a greater effect on FC than the on-site spatial determinants, indicating the greater influence of drivers beyond the 25 km2 unit. In the case of protected areas, we unexpectedly find that protection in neighboring locations leads to higher forest degradation, suggesting a potential leakage effect, while protected areas in the local vicinity have a positive influence on FC. The Mann-Kendall trend statistic of occurrences of fires and conflicts over the time period and until 2020 show that significant increases in conflicts and fires are spatially divergent. Overall, our results highlight how assessing the proximate causes of forest degradation with spatiotemporal analysis can support targeted interventions and policies to reduce forest degradation but spillover effects of proximal drivers in neighboring areas need to be considered.

description: Small business owners stand to benefit from generative AI technologies due to limited resources, yet they must navigate increasing legal and ethical risks. In this paper, we interview 11 entrepreneurs and support personnel to investigate existing practices of how entrepreneurs integrate generative AI technologies into their business workflows. Specifically, we build on scholarship in HCI which emphasizes the role of small, offline networks in supporting entrepreneurs' technology maintenance. We detail how entrepreneurs resourcefully leveraged their local networks to discover new use cases of generative AI (e.g., by sharing accounts), assuage heightened techno-anxieties (e.g., by recruiting trusted confidants), overcome barriers to sustained use (e.g., by receiving wrap-around support), and establish boundaries of use. Further, we suggest how generative AI platforms may be redesigned to better support entrepreneurs, such as by taking into account the benefits and tensions of use in a social context.

Subjects: biodiesel, microalgae, renewable energy, photobioreactors.

description: Currently, the continued use of petroleum-based fuels is considered unsustainable due to resource depletion and the accumulation of greenhouse gases in the environment, in addition to land and water degradation. Therefore, biofuels from renewable sources can be an alternative to reduce the consumption of fossil fuels and contribute to maintaining a healthy global environment and economic profitability. Unfortunately, biodiesel produced from food stocks generally consumed by humans and animals can be a source of increased food market prices due to the increased use of arable land for growing biomass for the production of first and second generation biofuels. The production of biofuels from microalgae, as a third generation of biodiesel production, has some distinctive advantages, such as their rapid growth rate, greenhouse gas binding capacity and high lipid production capacity. This mini-study examines the current status of algae-based biofuels as a renewable energy source and their impact on the environment.
