In this study, the synthesis and manufacture of MgB2/SS 316L Superconducting Wire by In-Situ method through hot rolling with a variety of sintering temperature and holding time with the novelty of the SS316 sheath and hot rolling method were carried out to maintain the size reduction results without stress concentration and minimal defects. MgB2 is a superconducting material with a critical temperature of ~39 K. Hot rolling process with a variety of sintering temperature and holding time was carried out to observe its effect on the superconductivity characteristics of MgB2.The process of synthesis and sample preparation begins by measuring and cutting the SS3I6L tube and weighing the raw materials, which were Mg and B powders with a ratio of 1:2 according to stoichiometric calculations. The material was then grounded for 2 hours using an agate mortar and then put into an SS 316L stainless steel tube where it was completely compacted. Then, the sintering process was carried out using a muffle furnace with variations in sintering temperature of 7800C, 8000C, 8200C and holding time for 1 hour and 3 hours. After that, hot rolling process was carried out on each sample with a temperature of 3000C. The samples were characterized by XRD, Cryogenic Magnet and SEM-EDS. The identification through XRD showed that the phases formed were MgB2, MgO, Fe. The Cryogenic Magnet test showed superconductivity at a sintered temperature of 8000C and 8200C with a holding time of 1 hour, where for a sintered temperature of 8000C, it has a Tconset of 39.55 K and a Tczero of 34.69 K while at sintered temperature of 8200C the TcOnset is 38, 44 K TcZero is 31.30 K. However, in the MgB2 sample, the sintered temperature of 7800C with a holding time of 1 hour did not show superconductivity properties. Meanwhile, sintering temperature variation of 7800C, 8000C, 8200C with a holding time of 3 hours showed superconductivity properties, namely the appearance of TConset and TCzero in each sample. The morphological structure and elemental composition were seen through SEM-EDS, where the surface morphology had a hexagonal grain shape. As the sintering temperature and holding time increase, the surface morphology of the grains becomes denser and more regular so that the porosity is smaller.

The depletion of conventional energy sources, the global quest to reduce greenhouse emissions and the exponential increase in fossil fuels are several reasons that there is more focus on hybrid renewable energy systems (HRES). HRES are deployed to, improve energy security, address the increase in energy demand, and mitigate against environmental degradation while reducing greenhouse gas emission to achieve socio-economic development. Power plants are particularly located closer to the load mostly in cities where they are far from rural areas. HRES microgrids provide an alternative to the grid in rural areas where it is inaccessible due to distance and terrain. The volatility of HRES requires an energy storage system for power balancing and provides continuous power flow even during power fluctuation from renewable sources. Energy management strategy is a necessity in such systems for reliability; provide good power quality, and optimal use, of distributed energy sources in the system. This paper hereby proposes an energy management system (EMS) which is a control technique for managing power flow in response to demand, supply, and storage conditions. This hybrid microgrid energy system is composed of a photovoltaic (PV) system, a micro-hydropower (MHP) system, and a Lithium-ion battery storage system to supply a 180kW load. The energy management strategy is designed to maintain the supply to the load by dispatching battery power when there is a drop in irradiance and absorb power when there is access. The system is implemented in accordance with IEC/ISO 62264 using internal control loop and primary control. The system is modelled in a Matlab/Simulink environment with various scenarios and the results obtained show immediate power injection from the battery storage system when there is a drop-in renewable power which helps to maintain power and voltage despite the fluctuation.

The Yolov5 uses the self-adaptive anchor method instead of the traditional calculation method. Instead of calculating the anchor size based on the dataset label, it can also set the anchor size as a parameter. Unet is popularly used in medical image segmentation. In this article, we will introduce a new approach for the end-to-end extraction of the eyelid. It is a process that involves three steps, namely, de-noising, preliminary extraction, and precise eyelid segmentation. Y-UNet are both useful tools for identifying small targets. In addition, their ability to effectively segment or adhesive eyelid has been optimized. We optimized the overlap between U-Net and YOLOv5 for eye blinking. The objects detected in the yolov5 model that is higher version of Yolo should be masked on the images processed by the U-Net model with color segmentation of each objects. Moreover, in a preprocessing stage we use Kalman filter is very fast and are well suited for real time problems and embedded systems. This filter is a simple algorithm that predicts and separates random signals from noise. It can also detect the presence of noise and prevent it from generating an error. Automatic eye blinking detection is an important component of glaucoma diagnosis. In this research, Human eye blinking ratio calculation mainly used for detection of abnormal eye at early stage using our proposed Y-Unet model.

Small crab by-product such as non-crab shells waste is a potential source of proteins and amino acids. Therefore, this research was to examine the non-shell small crab amino acid and determine the effect of hydrolysate processing on amino acid levels. The study used crab (Portunus Pelagicus) lemi as part of the non-shell crab waste. Lemi was converted into hydrolysate using the alcalase enzyme. Amino acid profile was analyzed before and after the hydrolysis process. UHPLC (Ultra-High-Performance Liquid Chromatography) was used to determine the level of amino acids level. The use of hydrolysis technology increased the total of amino acids by 45.83%, from 21.32 g.100 g-1 to 31.09 g.100 g-1. The percentage of essential amino acids compared to non-essential amino acids is 58.06% of the total amino acid from the hydrolysate of a non-shell small crab waste. The hydrolysis technology also increases the chemical score. The amino acid histidine had a high chemical score after the hydrolysis process. The study suggested that by-products derived from small crab waste can be considered essential sources of proteins and amino acids for malnutrition disease.

One of the important steps in the production of geo-polymer concrete is the curing process, because temperature and duration of curing affect the compressive strength of the geo-polymer concrete. This study aims to determine the effect of steam curing temperature and duration on the compressive strength of geo-polymer concrete. All concrete specimens are cylinders with diameter of 15 x 30 cm cured with the steam. The steam temperatures will be controlled from 60 0C, 70 0C, 80 0C, 90 0C and 100 0C and the duration of curing will vary1 hour to 4 hours. In order to have the normal concrete strength the authors used the mix design of geo-polymer concrete based on the activator solution consist of Sodium Hydroxide (NaOH) 6 Molarity and Sodium Silicate gel (Na2SiO3). The specimens were tested for compressive strength test at the age of 28 days. It can be concluded that the right steam curing method and equipment could increase the compressive strength of geo-polymer concrete up to 100 % compared the concrete specimens cured in the room temperature.

The paper presents the results of a study of the environmental impact of industrial waste - grinding sludge. Atomic emission spectroscopy was used to determine the content of 25 elements in aqueous and acetate-ammonium waste extracts. It was found that, in terms of mass content, the priority elements in the water extract are Ca, B, Mg, Fe, Si, Sr, the priority elements in the acetate-ammonium extract are Fe, Ca, Mn, Cr, Si, Ni, B. To assess the environmental hazard of the analyzed elements for environmental objects, the calculations of the multiplicity of exceeding the standard indicators, as well as the indices of environmental impact were carried out. According to the results of calculations, it was determined that the water extract of grinding sludge is characterized by the level of toxic water pollution as "highly toxic (dirty)", acetate-ammonium - "extremely toxic (extremely dirty)". In the case of aqueous extracts of grinding sludge, the main contribution to the pollution of drinking water is made by soluble compounds B, Ca and Fe, to the pollution of natural water - Fe, B, Mn and Zn, in acetate-ammonium extracts - heavy metals - Fe, Cr, Mn, Ni, Pb and Cd. The most significant increase in the acetate-ammonium buffer is the increase in the environmental impact indices for six priority elements on the water of water bodies for domestic drinking and cultural and domestic water use (by 2734 times) and on water of water bodies of fishery significance (by 9648 times). Accordingly, the contact of grinding sludge with natural water, which exhibits buffering and complex-forming properties with respect to heavy metals, leads to its significantly greater contamination with the studied heavy metals in comparison with tap, distilled or non-contaminated natural water. The placement of grinding sludge in soil (soil) with filtration soil water, in wet soil, in soil with rain and melt water will lead to significant emission of mobile forms of heavy metals and pollution of the soil landscape and adjacent environments, which in turn requires the introduction of additional measures aimed to reduce the toxicity of the above waste.

Acrylonitrile-butadiene rubber (NBR) composites were development with hybrid filler from silica and coarse particles of pumpkins seed husk (PSH). Bis (triethoxy-silylpropyl) tetrasulfide (TESPT) was used as coupling agent. Other ingredients used: polar plasticizer, antioxidant, aid process and sulfur curing system. PSH was mercerized with dilute NaOH solution. The compounding was carried out in a laboratory size two-roll miller; the TESPT was added directly in the mixing stage. The rubber composites were vulcanized using compression molding in a laboratory press. Four NBR vulcanizates were made to evaluate the effect of mercerized PSH and silane on the mechanical properties. It was found that the incorporation of PSH affected the curing characteristics, hardness, tensile strength, elongation at break and abrasion resistance in hybrid composites. The presence of TESPT in the hybrid compound improved the tensile and elongation properties. However, the presence of large PSH particles probably limited silane's performance on other properties. PHS is a waste of seeds husk from pumpkin fruits (genus Curcubita). Fine PHS particles can be an alternative to elaborate hybrid rubber compounds since it allows achieving a good balance between mechanical properties and friendly environmental production.

This paper introduces a method to prepare an engine for very long flights without maintenance. It also gives criteria to estimate time between overhaul by using the sensor data to have an estimation of the engine condition. In-flight refueling has introduced new challenges to UAV (Unmanned Aerial Vehicle) propulsion systems. It is now possible to run continuously an UAV without landing for long periods. For this task, it is necessary to carry a quantity of lubricant sufficient for at least one month (approximately 800h). For extremely long flights, diesel piston engines are better than spark ignition ones due to extremely low fuel consumption. A selection in the assembly line individuates those engines that are suitable for long endurance flight. This is possible because automotive engines are manufactured in thousands per day and many quality controls take place in the assembly process. Moreover, mass produced automotive engines pass several tests during the assembly process including a very short run. The results of these tests are useful for an initial selection. Then, a 25-hour trial with a very thin lubricant is sufficient to forecast the oil consumption up to 1,000 hours. The 25 hours run corresponds to the time necessary to stabilize the oil consumption rate. In addition, during the 25 hours run also the electronic infancy failures are detected. In modern engines, the electronic on board diagnosis, the full redundancy of vital sensors, electronic control units and batteries/generators, make it possible to fly safely without emergencies with random electronic failures of components and wiring. Another major requirement is to forecast the engine failure or an unacceptable deterioration in terms of mechanical performance. This paper introduced a method to evaluate the state of wear of the engine starting from a digital monitoring system. A wear model of the engine based on the real duty cycle is proposed. It is then possible to prolong the life of the engine and to increase the time between overhaul. It is also possible schedule the overhaul operation.

In this paper we propose a new implementation of an algorithm for the morphological analysis system of Arabic words which is based on the finite state automatons. This system combines the Buckwalter approach and the finite state automaton approach. We offer a reimplemented version of the tool which adapts the automatons in the form of a network of literates, from a set of words from the input Arabic language and from the tool which itself performs the morphological analysis, This system is based on very restricted dictionaries and searches for solutions in a global network using the Viterbi algorithm which proposed the optimal solutions to the analyzer. Our approach was tested on a corpus of 10,000 Arabic words. The results obtained are very impressive and show the importance of our new approach.
