Improving the Performance of Single-Intersection Urban Traffic Networks Based on a Model Predictive Controller
Authors: Jafari Sadiqa , Shahbazi Zeinab , Byun Yung-Cheol
Published: May 2021

The use of a Model Predictive Controller (MPC) in an urban traffic network allows for controlling the infrastructure of a traffic network and errors in its operations. In this research, a novel, stable predictive controller for urban traffic is proposed and state-space dynamics are used to estimate the number of vehicles at an isolated intersection and the length of its queue. This is a novel control strategy based on the type of traffic light and on the duration of the green-light phase and aims to achieve an optimal balance at intersections. This balance should be adaptable to the unchanging behavior of time and to the randomness of traffic situations. The proposed method reduces traffic volumes and the number of crashes involving cars by controlling traffic on an urban road using model predictive control. A single intersection in Tehran, the capital city of Iran, was considered in our study to control traffic signal timing, and model predictive control was used to reduce traffic. A model of traffic systems was extracted at the intersection, and the state-space parameters of the intersection were designed using the model predictive controller to control traffic signals based on the length of the vehicle queue and on the number of inbound and outbound vehicles, which were used as inputs. This process demonstrates that this method is able to reduce traffic volumes at each leg of an intersection and to optimize flow in a road network compared to the fixed-time method.
Towns, High Streets and Resilience in Scotland: A Question for Policy?
Authors: Sparks Leigh
Published: May 2021

The “death of the high street” has become a common refrain, particularly in the United Kingdom, often accompanied by calls for action and demands for improved resilience in town centres and high streets. This paper considers the policy context for towns and town centres in Scotland and the recent review of the country’s approach to towns, town centres and places. With the adoption of National Outcomes linked to the United Nations Sustainable Development Goals and the declaration of a Climate Emergency, the conclusion is drawn that a more fundamental and radical shift in policy is needed, if the resilience of town centres is to have any meaning, and that a clearer and more widely understood conceptualisation of resilience needs to be developed.
Comparing Passenger Satisfaction, Employees’ Perspective and Performance on Quality and Safety Indicators: A Field Study
Authors: D’Alonzo Luca , Leva Maria Chiara , Bucciarelli Edgardo
Published: May 2021

This paper aims to analyze the impact that different attributes related to a Regional Airport service and the socio-economic factors of the passengers have on the passenger’s overall satisfaction. The study also compared passenger and employee satisfaction in relation to the service offered by the airport, to identify possible critical areas of improvement. An Ordinal Logistic Regression (OLR) approach was used to model how the attributes considered for qualifying airport services and the socio-economic variables impact the predicted variable (i.e., passenger satisfaction). Furthermore, the results were triangulated to include quality and safety performance indicators as an objective anchor point for the performance of the company. The findings indicate interesting areas of difference between the perceptions of the passengers and airport employees regarding a company’s services and its performance. The company managers in the key areas of operation were then asked to select the main areas of improvement among the ones highlighted by the survey’s results. Quality and safety indicators were also helpful in enriching the analysis and indicating good synergy with the suggestions collected from the passengers’ and the employees’ surveys, offering yet another complementary perspective.
How the Balanced Scorecard Is Implemented in the Spanish Footwear Industry
Authors: Suárez-Gargallo Carlos , Zaragoza-Sáez Patrocinio
Published: May 2021

This paper provides a deeper knowledge of the implementation of the Balanced Scorecard (BSC) in the Spanish footwear industry, under an exploratory research which has been conducted with a final sample of seven firms. An online questionnaire was developed, supported by phone calls and a personal interview. An 18–24-month-period has been found to be enough to develop solid foundations for a BSC. Financial and non-financial measures are presented in the whole firms and in the majority of the four perspectives, linked by cause-and-effect relationships, showing a high development in the BSC implementation. BSCs with a high grade of development are more likely to identify their intangibles as well as include them in the firm’s strategy. A personal BSC has been identified as a limitation. Although the strategy is spread out with meetings in the whole firms, it is not known at all levels, showing a gap to be fulfilled. Strategy maps are key in BCS implementation: they are present in the majority of the firms and show that the performance drivers reach the strategy. Firms with a high grade of development and expectation, using both financial and non-financial measures linked by cause-and-effect relationships, are more likely to define sustainable measures, integrating them in their own BSC.
Collaborative Optimization of Storage Location Assignment and Path Planning in Robotic Mobile Fulfillment Systems
Authors: Cai Jianming , Li Xiaokang , Liang Yue , Ouyang Shan
Published: May 2021

The robotic mobile fulfillment system (RMFS) is a new automatic warehousing system, a type of green technology, and an emerging trend in the logistics industry. In this study, we take an RMFS as the research object and combine the connected issues of storage location assignment and path planning into one optimization problem from the perspective of collaborative optimization. A sustainable mathematical model for the collaborative optimization of storage location assignment and path planning (COSLAPP) is established, which considers the relationship between the location assignment of goods and rack storage and path planning in an RMFS. On this basis, we propose a location assignment strategy for goods clustering and rack turnover, which utilizes reservation tables, sets AGV operation rules to resolve AGV running conflicts, and improves the A-star(A*) algorithm based on the node load to find the shortest path by which the AGV handling the racks can complete the order picking. Ultimately, simulation studies were performed to ascertain the effectiveness of COSLAPP in the RMFS; the results show that the new approach can significantly improve order picking efficiency, reduce energy consumption, and lessen the operating costs of the warehouse of a distribution center.
Design of Protected Area by Tracking and Excluding the Effects of Climate and Landscape Change: A Case Study Using Neurergus derjugini
Authors: Vaissi Somaye
Published: May 2021

This study aimed to use the applications of Ensemble Species Distribution Modelling (eSDM), Geographical Information Systems (GISs), and Multi-Criteria Decision Analysis (MCDA) for the design of a protected area (PA) for the critically endangered yellow-spotted mountain newt, Neurergus derjugini, by tracking and excluding the effects of climate and landscape changes in western Iran and northeastern Iraq. Potential recent and future distributions (2050 and 2070) were reconstructed by eSDM using eight algorithms with MRI-CGCM3 and CCSM4 models. The GIS-based MCDA siting procedure was followed inside habitats with high eSDM suitability by eliminating the main roads, cities, high village density, dams, poor vegetation, low stream density, agricultural lands and high ridge density. Then, within the remaining relevant areas, 10 polygons were created as “nominations” for PAs (NPAs). Finally, for 10 different NPAs, the suitability score was ranked based on ratings and weights (analytical hierarchy process) of the number of newt localities, NPA connectivity, NPA shape, NPA habitat suitability in 2070, NPA size, genetic diversity, village density and distance to nearest PAs, cities, and main roads. This research could serve as a modern realistic approach for environmental management to plan conservation areas using a cost-effective and affordable technique.
Trend, Status, and Challenges of Irrigation Development in Ethiopia—A Review
Authors: Gebul Mekonen Ayana
Published: May 2021

Ethiopia’s food supply and economy in general is largely dependent on rain-fed agriculture. Hence, irrigation development is vital to minimize the risk of crop failure and sustain agricultural production. The purpose of this review was to collect published and unpublished information from relevant sources and then review and synthesize key information on the trends and status of irrigation development and challenges threatening its implementation and sustainability. Historically, traditional irrigation based on farmers’ own initiative and indigenous knowledge has been practiced in Ethiopia for over 2000 years. However, well-planned, government-funded medium and large-scale irrigation development started only three decades ago. Specifically, significant progresses have been registered during the implementation of two consecutive five-year plans, the “Growth and Transformation Plans”. Currently, the total area equipped for irrigation has reached some 3.07 million hectares. However, the actual area irrigated is lower than this figure. The challenges facing the irrigation sector are related to study and design, construction or implementation, irrigation management, and lack of other support services such as extension, input services, and market. While the expansion of irrigation is still important, the poor performances and operational management of existing irrigation schemes needs to be given equal attention. As many of the problems are related to capacity and capability limitations, there is an urgent need for institutional and capacity development for the irrigation sector.
Flood4castRTF: A Real-Time Urban Flood Forecasting Model
Authors: Craninx Michel , Hilgersom Koen , Dams Jef , Vaes Guido , Danckaert Thomas , Bronders Jan
Published: May 2021

Worldwide, climate change increases the frequency and intensity of heavy rainstorms. The increasing severity of consequent floods has major socio-economic impacts, especially in urban environments. Urban flood modelling supports the assessment of these impacts, both in current climate conditions and for forecasted climate change scenarios. Over the past decade, model frameworks that allow flood modelling in real-time have been gaining widespread popularity. Flood4castRTF is a novel urban flood model that applies a grid-based approach at a modelling scale coarser than most recent detailed physically based models. Automatic model set-up based on commonly available GIS data facilitates quick model building in contrast with detailed physically based models. The coarser grid scale applied in Flood4castRTF pursues a better agreement with the resolution of the forcing rainfall data and allows speeding up of the calculations. The modelling approach conceptualises cell-to-cell interactions while at the same time maintaining relevant and interpretable physical descriptions of flow drivers and resistances. A case study comparison of Flood4castRTF results with flood results from two detailed models shows that detailed models do not necessarily outperform the accuracy of Flood4castRTF with flooded areas in-between the two detailed models. A successful model application for a high climate change scenario is demonstrated. The reduced data need, consisting mainly of widely available data, makes the presented modelling approach applicable in data scarce regions with no terrain inventories. Moreover, the method is cost effective for applications which do not require detailed physically based modelling.
From User to Provider: Switching Over in the Collaborative Economy
Authors: Ertz Myriam , Deschênes Jonathan , Sarigöllü Emine
Published: May 2021

The collaborative economy comprises resource circulation systems where consumers can act as both obtainers and providers of products and services. Despite considerable research on collaborative economies, there is a dearth of understanding of how individuals switch from being an obtainer to a provider. We address this void in the literature. The objective of this paper is to conceptually introduce and empirically substantiate the switchover concept, which occurs when an individual switches from a user role to a provider one—drawing on 31 in-depth semi-structured interviews with collaborative economy obtainers. The findings suggest that personal values, learning experience, social benefits, mutuality, and peer influence drive obtainers to become providers. In contrast, distrusting strangers, a sense of intimacy, a lack of resources to share, and a lack of skills inhibit the switchover process. Our findings contextualize the drivers and inhibitors idiosyncratically to convert obtainers into providers, offer important implications for managers, contribute to the collaborative economy and sharing economy literature and suggest compelling avenues for future research.
Urban Planning Policies to the Renewal of Riverfront Areas: The Lisbon Metropolis Case
Authors: Medeiros Eduardo , Brandão Ana , Pinto Paulo Tormenta , Lopes Sara Silva
Published: May 2021

Urban planning offers various design possibilities to solve fundamental challenges faced in urban areas. These include the need to physically renew old industrial and harbour riverside areas into liveable, inclusive and sustainable living spaces. This paper investigates the way urban planning policies have helped to renew the waterfront areas in the Lisbon metropolis in the past decades. For this purpose, the contribution of the European Union (EU) and national urban development plans over the past decades are analysed. The results demonstrate an intense renewal of the waterfront areas in the Lisbon metropolitan area (LMA), particularly in Lisbon over the past three decades into leisure, ecologic and touristic areas, vis-à-vis the previous industrial and harbour vocation.
An Extension TOPSIS Method Based on the Decision Maker’s Risk Attitude and the Adjusted Probabilistic Fuzzy Set
Authors: Liu Donghai , Huang An , Liu Yuanyuan , Liu Zaiming
Published: May 2021

The paper studies an extension TOPSIS method with the adjusted probabilistic linguistic fuzzy set in which the decision maker’s behavior tendency is considered. Firstly, we propose a concept of probabilistic linguistic q-rung orthopair set (PLQROS) based on the probability linguistic fuzzy set (PLFS) and linguistic q-rung orthopair set (LQROS). The operational laws are introduced based on the transformed probabilistic linguistic q-rung orthopair sets (PLQROSs) which have the same probability. Through this adjustment method, the irrationality of the existing methods in the aggregation process is avoided. Furthermore, we propose a comparison rule of PLQROS and the aggregated operators. The distance measure of PLQROSs is also defined, which can deal with the symmetric information in multi-attribute decision making problems. Considering that the decision maker’s behavior has a very important impact on decision-making results, we propose a behavioral TOPSIS decision making method for PLQROS. Finally, we apply the practical problem of investment decision to demonstrate the validity of the extension TOPSIS method, and the merits of the behavior decision method is testified by comparing with the classic TOPSIS method. The sensitivity analysis results of decision-maker’s behavior are also given.

Published: May 2021

A boundary value problem for Hadamard fractional differential equations of variable order is studied. Note the symmetry of a transformation of a system of differential equations is connected with the locally solvability which is the same as the existence of solutions. It leads to the necessity of obtaining existence criteria for a boundary value problem for Hadamard fractional differential equations of variable order. Also, the stability in the sense of Ulam–Hyers–Rassias is investigated. The results are obtained based on the Kuratowski measure of noncompactness. An example illustrates the validity of the observed results.

Published: May 2021

By the middle of 2021, we are still immersed in the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The concurrence of this new pandemic in regions where human immunodeficiency virus (HIV) and tuberculosis (TB) infections possess the same epidemiological consideration, has arisen concerns about the prognosis, clinical management, symptomatology, and treatment of patients with triple infection. At the same time, healthcare services previously devoted to diagnosis and treatment of TB and HIV are being jeopardized by the urgent need of resources and attention for COVID-19 patients. The aim of this review was to collect any article considering the three conditions (HIV, TB, and SARS-CoV-2), included in PubMed/Medline and published in the English language since the beginning of the COVID-19 pandemic. We focused on detailed descriptions of the unusual cases describing the three co-infections. Eighty-four out of 184 publications retrieved met our inclusion criteria, but only three of them reported cases (five in total) with the three concomitant infections. The clinical evolution, management, and therapy of all of them were not different from mild/severe cases with exclusive COVID-19; the outcome was not worse either, with recovery for the five patients. Cases of patients with COVID-19 besides HIV and TB infections are scarce in literature, but studies deliberately embracing the triple infection as a priori inclusion criterion should be carried out in order to provide a complete understanding of joint influence.
A Comparative Investigation of Various Pedotransfer Functions and Their Impact on Hydrological Simulations
Authors: Mohajerani Hadis , Teschemacher Sonja , Casper Markus C.
Published: May 2021

Soil hydraulic properties, which are basically saturated and unsaturated hydraulic conductivity and water retention characteristics, remarkably control the main hydrological processes in catchments. Thus, adequate parameterization of soils is one of the most important tasks in physically based catchment modeling. To estimate these properties, the choice of the PTFs in a hydrological model is often made without taking the runoff characteristics of the catchment into consideration. Therefore, this study introduces a methodology to analyze the sensitivity of a catchment water balance model to the choice of the PTF. To do so, we define 11 scenarios including different combinations of PTFs to estimate the van Genuchten parameters and saturated hydraulic conductivity. We use a calibrated/validated hydrological model (WaSiM-ETH) as a baseline scenario. By altering the underlying PTFs, the effects on the hydraulic properties are quantified. Moreover, we analyze the resulting changes in the spatial/temporal variation of the total runoff and in particular, the runoff components at the catchment outlet. Results reveal that the water distribution in the hydrologic system varies considerably amongst different PTFs, and the water balance components are highly sensitive to the spatial structure of soil hydraulic properties. It is recommended that models be tested by careful consideration of PTFs and orienting the soil parameterization more towards representing a plausible hydrological behavior rather than focusing on matching the calibration data.

In the presented literature review, we conducted a meta-analysis of the effectiveness of 3 surgical treatment options for patients with pharmacoresistant temporal lobe epilepsy. Despite the widespread use of the new type of antiepileptic drugs, there are still more than 30 % of patients with epilepsy, which developed into pharmacoresistant epilepsy. Wiebe S. et al. conducted a randomized control trail (RCT) and proved that the one-year recovery rate of patients with temporal lobe epilepsy with surgical treatment was significantly higher than that with medication treatment (58 % vs. 8 %). This study proves that surgery can be effective in treating pharmacoresistant temporal lobe epilepsy [10]. Additionally, it was found that the surgically treated patients at 6 months postoperative follow-up achieved a positive minimum clinically significant change (MCID) in quality of life in epilepsy (QOLIE)-89, compared to those in the medical group (56,0 % vs. 11,0 %, p < 0,001), while 62.0 % of the surgical group achieved a positive MCID value on QOLIE-31 (p < 0,001) compared to 17,0 % in the medical group.

INFLUENCE OF DIFFERENT ASSORTMENT OF TWO-BALL GRINDING LOAD ON THE PERFORMANCE OF AN OPEN-CYCLE BALL MILL
Authors: Borisov I. , Stronin A.
Published: May 2021

The ball mill has an energy efficiency of no more than 3.5 % (taking into account the measures taken to intensify the process of grinding the material). This is due to the imperfection of the design of the grinding unit, which consists in the fact that it is impossible to completely convert the mechanical energy accumulated by the grinding load into grinding energy (i.e., energy directly spent on the destruction of material particles). Most of the stored energy is converted into heat, noise, and vibration. The existing directions of intensification of the grinding process are as follows: improvement of the design, internal equipment of the cement mill; changes in the physical and chemical properties of the grinding medium; improvement of the grinding scheme. The authors of this article work in the direction of improving the internal equipment, which is reflected in the scientifically based selection of the range of grinding media for the fine grinding chamber, since the rational composition of the grinding load can significantly reduce the energy consumption of the grinding process. The authors continue to study the possibility of using a two-ball loading in a fine grinding chamber. This article provides a brief overview of the different ranges of two-ball grinding loadings, which differ from each other only in the range of grinding media. The possibility of a significant increase in the productivity of the mill when replacing the traditional grinding load with a rational two-ball is shown

Published: May 2021

The Ramsar Convention on Wetlands is an international framework through which countries identify and protect important wetlands. Yet Ramsar wetlands are under substantial anthropogenic pressure worldwide, and tracking ecological change relies on multitemporal data sets. Here, we evaluated the spatial extent, temporal change, and anthropogenic threat to Ramsar wetlands at a national scale across China to determine whether their management is currently sustainable. We analyzed Landsat data to examine wetland dynamics and anthropogenic threats at the 57 Ramsar wetlands in China between 1980 and 2018. Results reveal that Ramsar sites play important roles in preventing wetland loss compared to the dramatic decline of wetlands in the surrounding areas. However, there are declines in wetland area at 18 Ramsar sites. Among those, six lost a wetland area greater than 100 km

, primarily caused by agricultural activities. Consistent expansion of anthropogenic land covers occurred within 43 (75%) Ramsar sites, and anthropogenic threats from land cover change were particularly notable in eastern China. Aquaculture pond expansion and
Spartina alterniflora
invasion were prominent threats to coastal Ramsar wetlands. The observations within China’s Ramsar sites, which in management regulations have higher levels of protection than other wetlands, can help track progress towards achieving United Nations Sustainable Development Goals (SDGs). The study findings suggest that further and timely actions are required to control the loss and degradation of wetland ecosystems.

Backgrounds: Bronchopulmonary sequestration (BPS) is a rare congenital anomaly of the lung that has two different types as intralobar and extralobar. In this study, we aimed to present six cases of intralobar sequestration with atypical findings in terms of feeding, drainage and, localization. Methods: Patients diagnosed with intralobar pulmonary sequestration in our clinic between 2015-2019 were evaluated retrospectively. Demographical features and atypical Computed Tomography (CT) findings of the patients were presented by literature. Results: Among 45 patients with intralobar sequestration, six ones (13.3%) (5 males and 1 female) with a mean age of 43.5±25.4 (0-78) years old) had atypical pulmonary findings on CT images. Atypical features regarding arterial supply was detected in 8.9%, venous drainage in 2.2%, location in 4.4%, radiological appearance ın 4.4% and co-existing lesion in 2.2% of the patient with intralobar sequestration. Conclusion: Typical and atypical features of pulmonary sequestration must be well-known for differential diagnosis of solid or cystic pulmonary lesions.

Published: May 2021

Tracking the path of development in different Engineering disciplines, it can be easily observed that, right from the primitive stage, several tools, devices, and techniques may be identified, which happened by virtue of the evolution of human intelligence, getting transformed into various engineering applications. Although, later different engineering disciplines evolved, where most of the exhaustive development could be undertaken in that discipline. Likewise, in the field of mechanical engineering to various types of mechanical systems, according to the requirement in that field, were developed, in order to provide support of mechanization. Prime movers used to be an important part of these mechanical systems, which provided energy input as well as actuation required for providing the machines the desired kinematics. Most of the mechanical systems developed has been operated by conventional engine system using one or other fuel. Apart from the actuation by mechanical means, there are other means also through which mechanical actuation with better control, flexibility, and manipulation may be utilized in mechanical systems. A different category of systems, called Mechatronic systems has been developed in the recent past, which involves the vivid scope of use of techniques, devices, and components generally used in various other engineering fields of electrical, electronics, hydraulics, and pneumatics, etc. Subsequently, there have been several inventions, design & development which have added new levels in every field. Mechanical systems have been generally composed of various mechanical elements, which are designed to follow certain kinematics. The performance of the Actuation system plays an important role in the overall performance of the mechanical systems. There are several alternative actuation systems, which are not mechanical. These actuation systems may be categorized into electrical, electronics, hydraulic and pneumatic types. The features of these actuation systems, are so peculiar, that typical kinematic movement may be manipulated that too with more precision. Better control of mechanical systems may be realized, which is otherwise difficult with mechanical systems. In this paper, an effort has been made to review the possibilities, prospects as well as scope with various actuation systems.

Published: May 2021

Manufacturing lot cycle time is the period required by a manufacturer for completion of a production process. It is an essential factor for determining the success of most manufacturing organizations, yet most research is based on studies made almost exclusively in the semiconductor industry and does not attempt to utilize the complete potential of recent breakthroughs in computational learning. Using real data collected from a medical device manufacturing company, this paper demonstrates the applicability of a semi-supervised deep learning framework for highly accurate cycle time prediction, using stacked Denoising Autoencoders to form fully connected deep neural networks and Convolutional Neural Network models. The proposed strategies for cycle time prediction can have a significant impact on product design decision optimization within the system which, in turn, facilitates reduction of costs, energy use, and the overall environmental impact.

Published: May 2021

Building structures are subjected to vibrations due to earthquake activity. There are many characteristics that induce irregularities in buildings. Apart from other reasons, these irregularities may be; many times; due to non-uniform distribution of mass, stiffness, or strength in the structure of the building. Due to such irregularities; buildings are subjected to some undesirable effects which make them weaker compared to regular buildings. Indian Standard code of practice IS 1893 – (Part 1): 2016 [1] details guidelines to be followed so that buildings are less and less irregular. Many times such guidelines may be the result of past studies of actual performances of buildings in seismic events. It is the intended purpose of this paper to bring a review of standard guidelines which are important for irregular buildings for preventing various typical damages to occur in seismic conditions. Typical examples of past damages have been provided to draw lessons.

Masonry infill walls are widely known to increase the lateral stiffness of the structure and for this reason, it is accepted all over the world. This paper presents a review work on the performance of infill framed structures that were damaged during several earthquakes. A study of the behavior of damaged buildings during different earthquakes in the world has been carried out. The mentioned earthquakes substantially caused damage to the RC buildings. The RC buildings were damaged primarily because of improper design and reinforcement detailing at the design phase and improper workmanship and quality control at the construction phase. The main objective of this paper is to describe and analyze the failure patterns observed in reinforced concrete frame buildings with masonry infill walls and without masonry infill walls all over the world.

This research aims to optimize the weight of already existing fire extinguishers containing Carbon Dioxide as per BIS standards IS 2190: 2010 and IS 7285-1: 2004. In the paper, an optimized and new design is proposed to minimize the weight of the pressure vessel making it easier to store in smaller compartments and also allowing faster hand-held use during an emergency. The weight has been reduced substantially by using proposed materials and FEA simulations were performed on the model to check for failures under the set test conditions with the aim to minimize the volume of metal used that is able to withstand the hydrostatic load of pressure gas. ANSYS Mechanical 18.2 was used for performing 3d pressure analysis while the model was designed on Solidworks 2016. A Multi Frontal Direct Solver was preferred to reach the solutions in every case. The analysis results of all the materials were compared and finally, a material was selected that was tough enough to clear the safety standards and extremely light so that even old people could use it without any issues. A simple shell of Titanium Grade-5 Alloy was found to be the proper and optimal choice to obtain good mechanical properties and lightweight.

Endüstride birçok üründe ve evlerimizde, vitaminler ve mineraller bakımından zengin olmasından dolayı yumurta yaygın olarak tüketilmektedir. Artan ihtiyacın hızlı bir şekilde karşılanması için tavuk çiftliklerinde yumurtaların toplanması, ağırlıklarına göre sınıflandırılması, sağlam/çatlak olanların ayrılması, paketlenmesi vb. işlemler için otomasyona geçiş yapılmıştır. Kabuğun çatlak olması durumunda içerisine zararlı mikroorganizmalar kolaylıkla girebileceği gibi yumurta içinin havayla temasından dolayı kısa sürede bozulmasına yol açacaktır. Çatlaklar gözle görülebilecek kadar büyük olabildiği gibi bazen de mikro boyutta olmakta insan gözüyle tespit edilememektedir. Bu çalışmada yumurta kabuğunun çatlak/sağlam olması durumunun sinyal işleme ve makine öğrenme tabanlı tespiti gerçekleştirilmiştir. Mekanik sistem vasıtasıyla kabuğa yapılan darbe neticesindeki oluşan akustik sinyal sistemdeki mikrofonla 50kHz örnekleme frekansında 0.2 sn süresince kayıt altına alınmaktadır. Kabuğu sağlam ve çatlak olan ayrı ayrı 50 yumurta verisi düzenekle kayıt altına alınıp veri seti oluşturulmuştur. Yumurta kabuğuna darbenin uygulanma anından sönümlenene kadarki zamanın tespiti için 0.74V eşik değeri kullanılıp bu değerden sonraki 680 veri alınmıştır. Bu verilere db4 ana dalgacığı ile 2. seviyeden Dalgacık Paket Dönüşümü (DPD) uygulanarak farklı frekanslı detay ve yaklaşım bileşenleri çıkartılmıştır. Her bir bileşenin entropi değeri hesaplanarak 1x4 boyutunda özellik vektörü elde edilmiştir. Çıkartımı yapılan özellik vektörünün yumurta kabuğundaki çatlağın tespitindeki etkinliğini belirlemek için Yapay Sinir Ağı (YSA) kullanılmıştır. %100 başarım elde edilmiş olup bir yumurtanın kabuk çatlak/sağlam belirleme süresi yaklaşık olarak 0.216sn’dir.

Published: May 2021

The development of products destined to cover specific needs plays an important role when it is possible to have feedback, in terms of functionality, on the part of the final user for the consolidation of the product. Seeking such consolidation and identifying opportunities for improvement, in this paper a redesign was made based on specific criteria to align the manufacturing to mass production. The following premises were raised: 1) validation of the de-sign proposal; 2) comparative and operational analysis; 3) geometry optimization for weight and production cost reduction. This paper proposes a new design of the drawbar body of a tractor (case study) and the theoretical framework is established taking the bases of the concurrent engineering to define and characterize the final architecture configuration. Is reported the methodology used for the development of this research and the results obtained by finite element analysis for architecture optimization. Finally, are presented the defined strategies for aligning manufacturing to production.

Evapotranspiration is a key element in calculating the surface energy balance, wáter balance and crop water stress and crop yield determination. However, it´s direct measurement or estimation is frequently complicated, since the diversity and complexity of the factors acting in this physical process. (morphological, physiological and soil factors). SEBAL (Surface Energy Balance Algorithm for Land) estimates ET based on satellite images, using the principles of surface energy balance producing excellent results as reported in several studies of different scientist authors; minimizing the cost and time for the ET determination for large vegetation zones. The objective of this research work was to estimate the potential evapotranspiration for the pomegranate crop in a commercial farm, located in Gomez Palacio, Durango, Mexico, by SEBAL using Landsat 8 satellite images during the crop cycle 2016. The results were validated with estimates of ET by the FAO 56 method, obtaining a Willmott concordance index of 0.96, which means good estimation precision.
PECULIARITIES OF PROCEDURAL PROCEDURE FOR INITIATING CRIMINAL CASES OF TAX OFFENCES
Authors: Stelmakh V.Yu.
Published: May 2021

The article analyses the peculiarities of the procedural procedure for initiating criminal cases of tax offences. The initiation of criminal proceedings for these crimes is of a public and legal nature, combining two public interests. The first interest is due to the need to initiate criminal proceedings in connection with the detection of a criminal act. The second interest is caused by the task of ensuring full payment of taxes. On this basis, when initiating criminal proceedings for a tax offence, a participant such as a tax authority carrying out certain criminal proceedings appears. The Modern Criminal Procedure Act provides for two procedures for initiating criminal proceedings under the category of offences under consideration. The first procedure applies in cases where the fact of the tax offence is revealed by the tax authority. The application to the preliminary investigation body is preceded by a procedure regulated by tax law to apply to the taxpayer in order to obtain payment of tax from him. Only in case of failure of the taxpayer to comply with this obligation and only after the expiry of certain terms the tax authority transmits the information to the preliminary investigation body. The second procedure is used in cases where the fact of the commission of a tax offence is identified directly by the preliminary investigation body. In this case, the tax authority gives an opinion on the existence in the taxpayer 's actions of the elements of the tax offence and provides calculations on the amount of the shortfall.
