Published: May 2021

Abstract
Agricultural production in greenhouses shows a rapid growth in many parts of the world. This form of intensive farming requires a large amount of water and fertilizers, and can have a severe impact on the environment. The number of greenhouses and their location is important for applications like spatial planning, environmental protection, agricultural statistics and taxation. Therefore, with this study we aim to develop a methodology to detect plastic greenhouses in remote sensing data using machine learning algorithms.
This research presents the results of the use of a convolutional neural network for automatic object detection of plastic greenhouses in high resolution remotely sensed data within a GIS environment with a graphical interface to advanced algorithms. The convolutional neural network is trained with manually digitized greenhouses and RGB images downloaded from Google Earth. The ArcGIS Pro geographic information system provides access to many of the most advanced python-based machine learning environments like Keras – TensorFlow, PyTorch, fastai and Scikit-learn. These libraries can be accessed via a graphical interface within the GIS environment.
Our research evaluated the results of training and inference of three different convolutional neural networks. Experiments were executed with many settings for the backbone models and hyperparameters. The performance of the three models in terms of detection accuracy and time required for training was compared. The model based on the VGG_11 backbone model (with dropout) resulted in an average accuracy of 79.2% with a relatively short training time of 90 minutes, the much more complex DenseNet121 model was trained in 16.5 hours and showed a result of 79.1%, while the ResNet18 based model showed an average accuracy of 83.1% with a training time of 3.5 hours.

Abstract
This paper presents a two-dimensional (2D) numerical model of soil erosion and sediment transport resulting from rainfall induced overland flow. It is a spatial and temporal dynamic model combining physical and empirical laws and comprises: i) An overland flow module that solves the two-dimensional unsteady water flow equations on an infiltrating surface; ii) A soil infiltration module that uses a combined Horton-SCS scheme; and iii) A soil erosion and sediment transport module that solves the two-dimensional sediment transport equation, distinguishing between rill erosion, interrill erosion and sediment deposition.
The performance of the model was evaluated by comparing its results with observed data from laboratory rainfall-runoff experiments on a two-directional 2.00 × 2.00 m2 soil flume set at 1% and 10% slopes in the x- and y-directions, respectively. The x-direction produced remarkably lower runoff and transported sediments than the y-direction. The numerical model significantly underestimated x-direction lower values of runoff and transported sediments. However, in the y-direction the model presented very good performance. Overall, in total terms (x- plus y-direction), the numerically simulated graphs of runoff and sediment transport were in very good agreement with corresponding experimental measurements, demonstrating the laboratory proof-of-concept of the model.
Experimental and numerical investigation of water-surface characteristics at crossing connected non-orthogonally to four flat channels
Authors: Jeong Yong-Wook , Jeong Woochang 
Published: May 2021

Abstract
Most studies on the flood flow characteristics at a crossing focus on channels connected orthogonally or at right angle, but studies on non-orthogonally connected channels remain limited. In this study, hydraulic-model experiments and numerical simulations are performed to analyze the characteristics of the water-surface variation in and around a crossing connected non-orthogonally to four flat channels. Comparison of the measured and simulated water depth distributions in and around the crossing indicates that the results are in relatively good agreement. In the experiment where the angle between two upstream channels is 45°, the water flow pattern in and around the crossing corresponds approximately to Type I proposed by Mignot et al. (2008). However, it was found that there is no any flow type to correspond to the water flow pattern measured in the case of the angle of 135°. For analyzing the variation of the water depth in and around the crossing with inflow, numerical simulation is performed by setting the inflow ratio of the two inlet channels to one, three, and six, respectively.

Abstract
Supply chain management is one of the most important elements of sustainable development. And due to the fact that the world market is driven by supply and demand, and the determinant of access to products is regional and international logistics, this paper focuses on the possibilities of implementing a green transport strategy in the context of sustainable development in logistic enterprises. This paper presents the results of the SWOT analysis pointing out the strengths, weaknesses, opportunities, threats of green vehicles market for the transport enterprises. It was noticed that the situation on the green vehicles market for the transport enterprises is characterized by the advantage of strengths and these strengths should be used to maximize the use of green vehicles. It emphasized that subsidies for green vehicles would allow to invest in a modern fleet, new solutions (e.g. own charging stations) can have an impact on the greater energy efficiency (self-sufficiency), increase of social awareness would force enterprises to take appropriate actions in the field of environmental protection and development of public transport based on green vehicles.
Multi-Period Age-Discriminated Perishable Inventory
Authors: Alrawabdeh Wasfi 
Published: May 2021

Abstract
In this paper, an extremely short shelf-life inventory of age-discriminated stochastic demand is considered. Age discriminated demand can be found in products of high circulation and short shelf-lives such as dairy products, packaged food, pharmaceutical products and medical products of short shelf lives. Simulation based optimization is considered to find the optimal order quantity. The model employs Discrete Event Simulation along with a modified simulated annealing algorithm. To validate the model and the optimization algorithm, the classical newsvendor problem is tested first, later, different experiments are carried out for different product lifetimes. In contrast to the classical newsvendor, this problem tackles a multi-period inventory of different ages and different demand distributions. The objective is to determine the optimal order quantity to satisfy the stochastic demand of all ages such that shortages and expirations are minimized. The results showed remarkable performance and outstanding minimum levels of shortage and expiration.

Published: May 2021

Abstract
Although some authors realized various measurement techniques and relevant standards in the experimental verification, the existing contributions still did not mention more complex automated workplaces with industrial robotic arm participation. To solve this, we provide a different view of the interconnection between individual devices (positioner, robot, etc.) controlled by third-party methods (Siemens products). Also, to obtain the necessary effectiveness, we tested and verified selected accuracy parameters for the participating device component (positioner). The proposed work tries to fulfill expectations for a precise welding technology (to ensure simultaneous movements of both the industrial robotic arm and positioner) to achieve higher quality and productivity. However, the components are from different manufacturers.

Published: May 2021

Abstract
Wireless ECG body sensor Savvy is a feasible solution for reliable and accurate long-term heart rhythm monitoring. However, there were no studies dealing with usability of this sensor in field testing. Accordingly, the aim of the study is to evaluate the quality of the ECG signal measured with wearable wireless ECG body sensor when used in field test settings and to determine how different types of sensor fixation affects the quality of the ECG signal during sub-maximal and maximal running settings. Twenty-three participants, 10 females and 13 males, were included in the study (20.56 ± 1.19 years). All subjects performed shuttle run (SR), Cooper 2400 m (C), and 100 m sprint test (S), once wearing the sensor attached to self-adhesive skin electrodes, additionally fixed with self-adhesive tapes, and secondly with the sensor attached to Polar belt and strapped around the chest. Test outcomes were compared applying the Student t-test for dependent variables, or the non-parametric Wilcoxon test, depending on the results of the normality test. The results showed a significant difference (p<0.05) in the running speed that provides an assessable ECG signal between two different types of fixation in all three running tests – C, S, SR, as well as between the parameters “QRS detected as negative”, “correct software detection”, and “detected QRS” in the C and SR tests. Findings obtained in this study proved that if properly fixed, the ECG signal recorded with wireless ECG can be efficiently used for heart monitoring during physical activities in real setting and potentially could be used as additional tool in detection of cardiovascular diseases. In addition, fixation with Polar belt is more adequate for measurements made during physical activity in real setting compared to fixation with tape.

Authors: Karibasappa C. Nagaraja  , Sampathkumar  
Published: May 2021

This study explores the performance on different components of the phonological awareness (i.e., rhyme generation (RG), phoneme deletion (PD), phoneme reversal (PR), syllable deletion (SD), syllable reversal (SR) and spoonerism (Spo) among 4th, 5th and 6th grade children. A total of 110 children (31-4th, 41-5th and 38-6th graders) spoke only one language, and Kannada was their mother tongue. The results indicate that there is a slight increase in performance on all components of phonological awareness. However, there are no significant differences in performance on component skills of phonological awareness across the grades observed except from syllable reversal. The results also reveal that a better performance, from all the groups, on syllable and rime tasks when compared to phoneme level tasks.
Extradural abscess following synthetic fabric duraplasty
Authors: Sapkota Shabal , Karn Mitesh 
Published: May 2021

Background:
Duraplasty refers to the neurosurgical process of reconstructing dural defect. Variety of materials is used for such reconstruction, including natural, semisynthetic, and synthetic materials. Although synthetic materials are readily available and easy to apply, these are associated with foreign body reaction which may lead to serious consequences in some cases. We describe one such rare instance of extradural abscess after polypropylene synthetic fabric duraplasty.

Case Description:
Our patient is a 33-year-old lady who suffered road traffic accident leading to massive brain laceration, contusion of bilateral frontal lobes, and anterior skull base fractures. Emergency craniotomy was carried out and dural defect repaired with polypropylene (G-Patch; G. Surgiwear® Ltd.) synthetic fabric as the duraplasty material. Three months later, the patient presented with discharging wound at the incision site. Neuroimaging showed ring enhancing lesion in frontobasal extradural space with cutaneous extension. The lesion failed to heal despite intravenous antibiotics and surgery was planned. Intraoperatively, abscess was found between G-Patch and dura. Histopathology showed granulomatous foreign body reaction. The lesion healed after synthetic dura removal and abscess drainage.

Conclusion:
Although various materials are used for duraplasty, there is no clear consensus on what material should be used for dural repair. Synthetic materials are bio-inert, offer good handling and malleability. Polypropylene has been used safely for both single- and double-layered duraplasty. However, foreign body reaction may occur and very rarely present as extradural abscess. Randomized trials should be done to establish the safety and efficacy profile of commonly used duraplasty materials.

Logic Synthesis for Emerging Technologies
Authors: Neutzling Augusto , Ribas Renato Perez 
Published: May 2021

Emerging technologies are being considered to replace the conventional CMOS-based design that seems arriving to its end of life due to the limits of MOS transistor shrinking. However, since those novel devices are not necessarily switch-based ones, the traditional AND/OR logic synthesis process in the digital integrated circuit design flow tends to become inefficient, whereas threshold logic paradigm seems to be more appropriate for them. In this context, different methods for threshold logic synthesis, suitable for emerging technologies, are reviewed in this paper. The majority logic based design is also discussed herein since it represents a subset of threshold logic domain, and many new technologies have presented the 3-input majority Boolean function as the most basic logic gate. Experimental data, presented in previous works, are used to illustrate and compare the performance of the state-ofthe-art logic synthesis methods related to
