Published: May 2022

Wear and tear are usually caused by various factors, which reduce the life span of a mechanical part. In the control engineering of an Electrohydraulic actuator system, the wear and tear can be caused by the system or the controller itself. This article examines the chattering effect that occurs during the sliding mode controller (SMC) design, and its effect on the nonlinear electrohydraulic actuator (EHA) system. To examine the chattering phenomenon, signum function is first applied on the switching function of the SMC. Then, parameters of the controller are obtained using single objective particle swarm optimization (PSO) method. These parameters are then applied to the switching function with hyperbolic tangent function. Lastly, the performance of both functions is analysed and compared based on graph and numerical data. From the output data, chattering phenomenon generated on the signum function is greatly eliminated by using hyperbolic tangent function.

Published: May 2022

The research contribution of the present work is to solve the path planning and path tracking problems in static and dynamic environments. A new Planning Navigation Algorithm Technique is developed in order to solve the problem of navigation with obstacle avoidance. The basic idea of this algorithm searches for a safe path for navigation. First, this algorithm is focused to identify an optimal collision-free route to a spatially defined objective. Then, in each displacement, the developed algorithm handles to maximize the distance between the obstacles and minimize the distance to the goal. This is to obtain the optimal trajectory for navigation. On the other side, a sliding mode controller is adopted to solve the tracking trajectory task. The basic idea of this control system is to allow the robot mobile to track the desired trajectory with minimum error. In addition, the comparative study between the proposed approach and the previous work is presented in order to demonstrate the satisfaction of the proposed strategy. Finally, simulation results which are developed using Matlab software are presented to show the robustness and efficiency of the developed algorithm and the reactivity of the proposed sliding mode controller.

Various aspects of the human workplace have been influenced by robotics due to its precision and accessibility. Nowadays, industrial activities have become more automated, increasing efficiency while reducing the production time, human labor, and risks involved. With time, electronic technology has advanced, and the ultimate goal of such technological advances is to make robotic systems as human-like as possible. As a result of this blessing of technological advances, robots will perform jobs far more efficiently than humans in challenging situations. In this paper, an automatic computer vision-based robotic gripper has been built that can select and arrange objects to complete various tasks. This study utilizes the image processing methodology of the PixyCMU camera sensor to distinguish multiple objects according to their distinct colors (red, yellow, and green). Next, a preprogrammed command is generated in the robotic arm to pick the item employing Arduino Mega and four MG996R servo motors. Finally, the device releases the object according to its color behind the fixed positions of the robotic arm to a specific place. The proposed system can also detect objects' geometrical shapes (circle, triangle, square, rectangle, pentagon, and star) and sizes (large, medium, and small) by utilizing OpenCV image processing libraries in Python language. Empirical results demonstrate that the designed robotic arm detects colored objects with 80% accuracy. It performs an excellent size and shapes recognition precision in real-time with 100% accuracy.

The cognitive architecture is investigated for the management in the nuclear power plant (NPP) site in which artificial intelligence (AI) is incorporated. The normal operation and accident are modeled for the simulations incorporated with the robot intelligence algorithm, where random sampling plays a major role in the quantifications. The Accident Dynamics Simulator paired with the Information, Decision, and Action in a Crew context cognitive model (ADS-IDAC) and the Cognitive skill for plant operations are calculated for the study. Simulations show the ADS-IDAC modeling and simulation results of two peaks in 21st and 21.75th sequences. Otherwise, there are several peaks with one big peak in 13.25th sequences. The big peak is in the 25.75th sequence in Mental State, Circumstances, and Identity. The accident situation is related to actions through the cognitive systems. In the operation case, a variety of signals are shown in which the operations of the plant could show several kinds of actions to be done by the robot. The figure shows the procedure of nuclear cognitive architecture. A nuclear accident is investigated by the designed modeling in which the actions of robots are quantified by the artificial brain. The developed algorithm of this paper could be applied to the other kinds of complex industrial systems like airplane operations and safety systems, spacecraft systems, and so on.

Published: May 2022

This paper investigates temperature modes of painting large metal structures in a tent-type drying chamber for the purpose of quality assurance and improving energy efficiency of the coating process. The research of several options of air removal out of a tent cover was performed. A SolidWorks model for a drying chamber with a large painted metal structure was developed in order to figure out temperature fields, air speed, and air trajectory. The model considers the joint effect of free and forced convection as well as aerodynamics of inner tent space on heating efficiency. The energy-saving design of the tent cover, which allows preheating air before the calorifier, has been proposed. As a result, a criterial equation has been obtained and energy efficiency optimization software has been developed.
Exploring the Relationships of Two Curriculum-improved Abilities Scales, Professional Development and Quantitative Skills, to Business Student Satisfaction and Employment Preparedness
Authors: Blau Gary , Goldberg Daniel , Voss Kathleen
Published: May 2022

Despite the pandemic, on-going efforts to evaluate student perceptions of their curricula improving their abilities across different areas needs to be continued. This study examined one business school’s undergraduate curriculum. Twelve individual item goals of this curriculum closely corresponded to what employers look for on college students’ resumes (NACE, 2021). Ninety-three Fall 2021 graduating business seniors filled out a survey asking their perceptions about the business school’s curriculum improving their abilities on these twelve goals. To date, these individual attributes have not been analyzed together in prior studies to produce a smaller set of research scales. A factor analysis of these twelve individual items resulted in keeping nine of these items, creating two new reliable and distinct scales for future research, labeled as Professional Development (5 items) and Quantitative Skills (4 items). Significant positive relationships between these two scales and two outcomes, student satisfaction and employment preparation, were subsequently found. In addition, a new short multi-item, reliable Employment Preparedness scale was developed. After controlling for record-based student demographics (gender, race, state residency) and school-related variables (GPA, transfer student, quantitative/qualitative major), Quantitative Skills accounted for significant variance in both outcomes, while Professional Development accounted for only student satisfaction.

Çalışmada dış ticaret üzerinde ciddi bir etkiye sahip olan paranın değer kaybı olgusunun, 2008 küresel krizi ile birlikte Türkiye’nin ithalat ve ihracat değerleri üzerindeki etkisinin belirlenmesi amaçlanmıştır. Bu amaçla 2008-Q1:2020-Q4 dönemi analiz edilmiştir. REDK (reel efektif döviz kuru), dış ticaret değerleri ve enflasyon değişkenleri için Augmented Dickey Fuller (ADF), Phillips Perron (PP) ve Zivot-Andrews (ZA) birim kök testleri ve kısa- uzun dönem katsayı tahminleri için sırasıyla Vektör Hata Düzeltme Modeli (VECM), Dinamik En Küçük Kareler Yöntemi (DOLS) ve Tam Düzeltilmiş En Küçük Kareler Yöntemi (FMOLS) yöntemleri uygulanmıştır. Değişkenler arasındaki nedensellik ilişkisi ise Toda-Yamamoto nedensellik analizi ile tespit edilmiştir. İki modelle yürütülen analizde elde edilen bulgular şu şekildedir: Ⅰ) Kısa dönemde REDK ithalatı azaltırken uzun dönemde hem REDK hem de enflasyon ithalatı azaltmıştır. Ⅱ) Kısa dönemde REDK ihracatı azaltırken enflasyon artırmış, uzun dönemde ise her iki değişken de ihracatı azaltmıştır. Ⅲ) Araştırılan dönemlerde ithalat ve enflasyon arasında çift yönlü nedensellik tespit edilirken, enflasyondan ihracata doğru tek yönlü nedensellik ilişkisi belirlenmiştir. Analiz sonuçlarından hareketle ithalat ve ihracat üzerinde enflasyon ve REDK’nin olumsuz etkisi göz önünde bulundurulduğunda, politikaların enflasyonu azaltıcı ve üretimi artırıcı yönde gelişmesi neticesinde dış ticaret ve makroekonomik dengesizliğin ortadan kalkacağı ifade edilebilir.
Study on Stability Analysis of Soil-Rock-Mixture Slopes under Freeze-Thaw Erosion in Greater Khingan Mountains
Authors: Zhao Yuxia , Liu Kangqi , Liu Hongyan , Xu Hanhua
Published: May 2022

Under the action of freeze-thaw erosion, slopes in permafrost regions frequently suffer from geological disasters. The unique properties of soil-rock-mixture slopes further complicate this freeze-thaw stability problem. To study the effects of freeze-thaw erosion on the stability of soil-rock-mixture slopes, several indoor tests were first carried out on the specimens collected from the target bare slope at the K105+750~K105+850 section of the Ali River to the Kubuchun Forest Farm along National Highway 332 in permafrost regions of Greater Khingan Mountains, and then, according to the test results, damage theory, strength reduction method, Python script, and ABAQUS numerical analysis software, the slippage and safety factor of the bare slope under freeze-thaw cycles were obtained, and finally, the damage degree of freeze-thaw erosion to the bare slope was quantified. To improve the stability of bare slope in the freeze-thaw environment, the composite ecological slope protection measures of arched skeleton + three-dimensional net + grass planting were finally selected, and its feasibility is verified with the help of on-site monitoring and numerical simulation; then, the long-term freeze-thaw stability of the slope after revetment was studied. Key findings indicated that (1) the threshold between soil and rock in the target slope was 5 mm, the soil-to-rock mass and volume ratios of the slope were 55.04% : 44.96% and 69.38% : 30.62%, respectively. (2) After the 150 freeze-thaw cycles, the peak strength and elastic modulus of the specimens decreased 59.7% and 79.50%, respectively. (3) Meanwhile, the freeze-thaw damage was 0.79. (4) The slope safety factor was inversely proportional to the number of freeze-thaw cycles. The target bare slope was unstable after 150 freeze-thaw cycles, and the safety stability reduction rate was 41%. (5) Compared with the bare slope, the shallow horizontal slip of the slope after revetment decreased from 1.528 m to 4.971 cm, and the slope safety factor increased from 0.997 to 4.501, which shows that the slope protection measures are initially feasible. In addition, the numerical analysis results are consistent with the field monitoring data, and the error between the two is ≤2.01%, which proves the rationality of the numerical model established in this paper and provides data support for subsequent research.
Neodymium Isotope Constraints on the Origin of TTGs and High-K Granitoids in the Bundelkhand Craton, Central India: Implications for Archaean Crustal Evolution
Authors: Joshi Kumar Batuk , Singh Sunil Kumar , Halla Jaana , Ahmad Talat , Rai Vinai K.
Published: May 2022

The Bundelkhand craton in central India consists mainly of abundant high-K granitoids formed at the Archaean-Proterozoic boundary and several enclosed rafts of TTGs (tonalite-trondhjemite-granodiorites) up to 3.5 Ga. Therefore, the Bundelkhand craton is a key locality for studies on Archaean crustal growth and the emergence of multisource granitoid batholiths that stabilised a supercontinent at 2.5 Ga. Based on their geochemical characteristics, the high-K granitoids are divided into low silica–high Mg (sanukitoids and hybrids) and high silica–low Mg (anatectic) groups. We aim to provide new insights into the role of juvenile versus crustal sources in the evolution of the TTG, sanukitoid, hybrid, and anatectic granitoids of the Bundelkhand craton by comparing their key geochemical signatures with new Nd isotope evidence on crustal contributions and residence times. The ages and geochemical signatures as well as εNd(t) values and Nd model ages of TTGs point towards partial melting of a juvenile or short-lived mafic crust at different depths. Paleoarchaean TTGs show short crustal residence times and contributions from the newly formed crust, whereas Neoarchaean TTGs have long crustal residence times and contributions from the Paleoarchaean crust. This may reflect the transition from melting in a primitive oceanic plateau (3.4-3.2 Ga) in plume settings, resulting in a Paleoarchaean protocontinent, to 2.7 Ga subduction and island arc accretion along the protocontinent. The 2.5 Ga high-K granitoids formed at convergent subduction settings by partial melting of the mantle wedge and preexisting crust. Sanukitoids and hybrid granitoids originated in the mantle, the latter showing stronger crustal contributions, whereas abundant anatectic granitoids were products of pure crustal melting. Our Nd data and geochemical signatures support a change from early mafic sources to strong crust-mantle interactions towards the A-P boundary, probably reflecting the onset of supercontinent cycles.

In this paper, microcomputed tomography (CT) imaging technique is adopted to image the microstructure of tight sandstones drilled from Chang-7 member in Yanchang Formation. The pore geometry, pore-throat size distribution, pore connectivity, and tortuosity of the pore-throat structure are quantitatively characterized by extracting the pore network model (PNM). Direct numerical simulation (DNS) approach is applied on the segmented CT images to investigate the anisotropic permeability of tight sandstones. In addition, the unstructured mesh model of the pore space is reconstructed, and the pore scale immiscible two-phase flow is simulated by computational fluid dynamics (CFD) using the volume of fluid (VOF) model. The results indicate that the pore-throat system of tight sandstone reservoirs is mainly composed of discontinuous intergranular pores and grain margin microfractures with poor connectivity and diverse pore morphology. The two-phase flow simulations indicate that the strong heterogeneity of pore-throat structure can lead to obvious fingering phenomenon of the injected fluid, which reduces the sweep efficiency and the oil recovery as well. The residual fluids are mainly trapped in tiny throats and dead-end pores. It is found that the digital rock analysis based on CT imaging can be a cost-effective and time-saving alternative to routine core analysis of tight sandstone reservoirs.
Efficacy of clay minerals for controlling aflatoxin B1 toxicity in commercial broilers
Authors: Akbar Saba
Published: May 2022

Aflatoxin occurrence in poultry feed causes aflatoxicosis in birds and poses health hazards to the consumers. Aflatoxin B1 (AfB1) is the most predominant and toxic metabolite that is controlled through addition of argillaceous clays as non-nutritive additives. Non-smectitic indigenous clay reserves need testing as AfB1 adsorbent. With detailed mineral and adsorption characteristics, three indigenous non-smectitic clays: (i) palygorskite, (ii) palygorskite-smectite mix, and (iii) interstratified smectite with hydroxy interlayered smectite were tested against 250 µg kg-1 AfB1 contamination in a poultry feeding trial with three replications at 1% and 2% (w/w) with positive and negative controls. A total of 330 Ross-308 male broiler chicks, initially reared on clean feed under controlled conditions of light and humidity, were distributed into eleven treatment combinations in a completely randomized design with 30 birds in each treatment on an equal weight basis with three replications at day 14 and fed on experimental feeds for three weeks. Three birds from each pen were randomly slaughtered at day 35 and for each replicated treatment, body weight gain, feed intake, and internal organs weight and morphology were recorded. AfB1 contamination reduced weight gain (p 0.0001), feed conversion ratio (p 0.0001) and feed intake (p 0.0001) while clays addition in the toxin feed effectively controlled AfB1 toxicity as suggested by improved body weight, weight gain rate and feed consumption compared to the toxin fed birds. The liver morphology was comparatively better in palygorskite-smectite mix treatment when applied at 1% and the darkish colour was also improved with addition of the clay in the toxin feed. AfB1 feeding caused a 75% reduction in weight gain compared to the clean feed. Palygorskite and palygorskite-smectite mix clays were better than interstratified clay in increasing weight gain and caused a 60% and 65% increase over toxin feed treatment when applied at 1% and 2%, respectively. In conclusion, the indigenous clay sources overall and palygorskite-smectite mix in particular has the potential for use as a mycotoxin binder for controlling AfB1 incidence in poultry

Micro sensors have large potential to measure soil nitrous oxide (N2O) emissions. However, because of its low sensitivity to get the electrical signals on soil with low moisture content, little research has been conducted in semi-arid agro-ecosystem. Moreover, the use of N2O microelectrode studies were largely focused on the marshy fields, paddy fields and waste waters with high soil moisture content. In order to characterize the boundary of the sensor signal (upper and lower), purified water without N2O is usually used as the calibration medium to calibrate the electrode. However, the physical and chemical properties of purified water and soil leaching solutions are very different. In this study, we improved and verified a microelectrode calibration method based on selecting appropriate media and optimal electrolyte concentration. In addition, we applied the improved microelectrode calibration method to continuously observe N2O flux from the soil column in a 30-day-long incubation experiment. The results pointed to noteworthy improvement of the microelectrode calibration compared to the current method, with soil solution validated as a calibration medium at optimal electrolytic concentration of 7:1-8:1, expressed as water/soil ratio. The emission of N2O from soil with different soil fertility were also significantly different. Our research is beneficial to establish the microelectrode calibration method of N2O emission under low moisture conditions from soil microenvironment, and also points on management practices of agro-ecosystem for N2O mitigation strategies

Evaluate silica fertilizer's effect on the quantitative and qualitative yield of forage sorghum (Sorghum bicolor L.) under drought stress. A split-plot experiment was implemented in a randomized block design with three replications in two cropping years, 2017-2018, in a farm located in the Varamin - Iran. The treatments included irrigation at three levels of 60, 120 and 180 mm of evaporation from class A's evaporation pan level. The main factor was silica fertilizer as non-consumption (control), foliar application and silica irrigation fertilizer as a secondary factor. Based on the obtained results, the treatment containing total chlorophyll, RWC and stomatal conductance was obtained from the 60 mm evaporation treatment and silica fertilizer use in irrigation water. The use of silica fertilizer as irrigation water reduced the Hydrogen cyanide content by 4%. The highest amount of crude protein was estimated to be 12.60 from 180 mm stress treatment and the use of silica fertilizer in irrigation water, which were 19% higher than the control treatment, respectively. The best sorghum dry forage yield was obtained from 60 mm evaporation irrigation and silica irrigation fertilizer with an average of 82.22 ton ha-1 , which was 52% higher than the 180 mm evaporation stress treatment.

During winter season, when the environmental temperature goes below the thermoneutral zone, it affects the performance of dairy cows. The objective of current study was to evaluate the influence of various types of housing systems on productive and physiological performance of Sahiwal cows in winter season. For this purpose, Twelve Sahiwal cows almost same weight (363±5kg), milk yield (6±0.5Lday-1 ) and 2nd parity (mid-lactation) were assigned to three experimental groups with four cows in each group. These groups are specified as; conventional barn (CB), open shed+curtain (O+C) and open shed (O) reared cows. Temperature-humidity index values were 63.8, 61.1 and 57.9 in CB, O+C and O groups respectively. Results showed that various types of housing systems had a significant effect on the performance of Sahiwal cows. The intake of dry matter was significantly higher in O reared cows (11.2 kg day-1 ) followed by the O+C (10.3 kg day-1 ) and CB reared cows (10.2 kg day-1 ). The intake of water was maximum in CB reared cows (17.7 L day-1 ) and was minimum in open shed reared O reared cows(14.4 L day-1 ) cows. Similarly, milk yield was maximum in CB readed cows (7.8 L day-1 ) and was minimum in O reared cows(5.2 L day-1 ) cows. No differences were observed in the composition of milk in CB, O+C and O reared cows. The rectal temperature (101.6 °F) was significantly lower in O reared cows followed by O+C and CB reared cows. Similarly, respiration rate was also lower (17.06 breaths min-1 ) in O reared cows followed by O+C and CB reared cows. Serum cortisol levels were significantly higher (21.1 ng/ml) in O reared cows as compared to other dietary treatments. It was concluded that production performance and physiological norms of indigenous Sahiwal cows can be improved by keeping them in conventional closed barn during the winter season.

PHY is very important enzyme in fish feed for the digestion of plant based diets as they have chelated compounds i.e. phytic acid. A seventy days experiment was conducted to study the effects of phytase (PHY) supplemented Moringa oleifera based diets on the growth efficiency of Tilapia fingerlings. Tilapia fingerlings were fed with a diet made up of mixture of Moringa seed and leaf meal (MSM and MLM). Anti-nutritional agents present in plant based products, decrease the nutrient edibility, utilization of minerals and shows negative impact on development. Seven isonitrogenous and isoenergetic diets were prepared by the addition of PHY (0, 500, 650, 800, 950, 1100 and 1250 FTU per kg) in Moringa based diet and 1% of chromic oxide as indigestible marker. Fingerlings were fed @4% of live wet weight two times daily and faeces were collected and analyzed at the end of the trial. Growth parameters were also checked on fortnightly basis. Based on outcomes, improvement in growth i.e., weight gain WG (24g), weight gain percentage (356%), FCR (1.21), SGR (1.69), nutrient digestibility (CP; 74%, EE; 70%, and GE; 69%) and absorption of mineral (Ca; 72%, Na; 71%, K; 71% and P; 75%) was noticed when fingerlings were fed at 950 FTU per kg level based diet as compared to control and other test diets. It was additionally noticed, that PHY addition diminished the release of nutrients and minerals through faeces that was resulted in decreased water contamination. On the basis of these results, it was concluded that addition of PHY @ 950 FTU per kg level is very useful to formulate cost-effective and eco-friendly fish feed by utilizing Moringa-derived products as compared to control and other test diets.
Sowing times affect flowering, pollen viability and seed yield of Zinnia elegans cvs. ‘Lilliput’ and ‘Super Yoga
Authors: Asghar Rimsha
Published: May 2022

A study was conducted to evaluate the influence of various sowing times on flowering, pollen viability and seed yield of zinnia (Zinnia elegans) cultivars ‘Lilliput᾿ and ‘Super Yoga᾿ under Faisalabad, Pakistan conditions. Seeds of both Zinnia cultivars were sown in 128-cell plug trays at 20 days interval from March 14 to August 20, during 2019. Seedlings were transplanted in thoroughly prepared field beds after 15 days of each sowing, according to factorial arranged randomized complete block design, with three replications. Data were recorded for various growths, flowering traits, pollen viability and seed related parameters. Super Yoga excelled over Lilliput for most the studied traits except number of lateral shoots, flowers per plant, unopened flower buds, pollen viability and seed yield per plant; values of these traits were higher for Lilliput than Super Yoga. Significant variation among various sowing times was recorded in both cultivars. Seeds sown on March 14, 2019 performed best compared to later sowing times for plant height, number of lateral shoots per plant, length of the lateral shoots, leaf area, number of flowers per plant, flower diameter, pollen viability, seed yield per plant and seed viability. However, total number of un-opened flower buds, seed weight per flower and 100-seed weight were more in April 03 sowing, although statistically similar to March 14 sowing. Seed yield declined gradually with delay in sowing; 66% less seed yield in June 20 sowing. Further delay in sowing did not produce seed. It was concluded that Zinnia should be sown by mid-March for getting high seed yield of good quality; later sowing, even during first week of April, resulted in 17.5% decrease in seed yield.
