Authors: Omelyanov Oleg , Tokarchuk Oleksii
Published: June 2022

The main effects of the broken design of the vibrating separator are: increased crushing force in the process of separating the slurry mass in this robot, which was moved by a path on the working container with a sieve of the conical shape of the vibrating ruh; a plethora of minds passing through a lot of products through the opening that they reached for the rahunka of the sieve surface of the bulk coliving; Changes in energy consumption and increase in the minds of robotic support units during the operation of the projected vibrating separator, which have been achieved by the addition of additional spring elements between the separator housing and bearing units of the vertical drive shaft of the vibration separator. The application of the proponated vibrating screen to the working organs of the volumetric kolivalny roar allows to increase the productivity and capacity of the process of distributing solid-state husky masses. To determine the rational parameters in the process of vibrating sieving, we took away the ratio of the rot of the victorious organs at the end of the sieve surface when victorious to the Lagrange method of the 2nd genus. When zastosuvanni Cauchy solutions for linear non-homogeneous differential lines, the remainder of the rozvnіz was eliminated. Removing the fallowness of the amplitude of the crushing, the vibratory characteristics and the vibration acceleration, the intensity of the crushing movement made it possible to carry out a mathematical analysis of the power and energy characteristics of the vibrodrive of the finished separator. The expansion of the conical sieve surface allows you to create expanses of gyration or colossal progressive movement, which allows you to realize the importance of a large separation of dry masses. The results of the analytical investigation made it possible to prime the optimal cut to the working sieve surface. On the basis of the analysis carried out, the grounding and clarification of the design parameters of the vibratory system were presented and the design of this technical system was presented.

Published: June 2022

The object of the study is the effect of ultrasound on raw meat. One of the promising areas of improvement and intensification of technological processes of food production is the use of ultrasound. Current research shows that ultrasound can play an important role at all stages of the food life cycle. Ultrasound depending on the mode of ultrasonic treatment, the degree of supersaturation of the solution, the temperature factor, etc. can significantly accelerate the process of denaturation of organic compounds. The range of application of ultrasound in the production of meat products by industrial means today is quite wide and includes: acceleration of maturation of raw meat, tendering of meat, its ambassador, heat treatment. The essence of the process of tendering meat with ultrasound is the use of ultrasonic vibrations to destroy the connective tissues of meat, thereby increasing its tenderness regardless of the process of maturation of meat, its appearance or processing conditions. Partial destruction and softening of tissue structures makes it possible to improve the consistency, juiciness, increase the permeability of pickles and accelerate enzymatic processes. The main goal of the research is to determine the impact of ultrasonic treatment on the quality and safety of meat products in the process of technological processing. The innovation of the work is the modernization of the stage of raw meat preparation due to the introduction of a flowing ultrasonic processor in the cooking apparatus. Ultrasonic radiation is applied during heat treatment, which improves the quality of the shot product and reduces cooking time. Acceleration of cooking is due to the rupture of the fibers at the cellular level.

In the course of the work, an experimental study of the effect of ultrasound on raw meat was conducted. According to the results of the experiment, a microscopic analysis of the protein structure was performed after exposure to ultrasound. An experimental result was obtained, which confirms the positive effect of ultrasound on raw meat. The technique used in the study can be used to study the effect of ultrasound on other materials.

Authors: Sevostianov Ivan , Melnik Oleksandr
Published: June 2022

Introduction of hydroponic installations is a prospective direction of agriculture, while they allow to get all-the-year-round fresh vegetables, fruits and greenery, including their exotic kinds for some regions. For provision of high efficiency of this equipment (minimal expenses of energy, materials and time, maximal productivity of the plants) there is important to supply the plants with optimal quantity of nutrients (nitrogen, potassium, sulfur, calcium, magnesium, phosphorus, natrium), microelements (iron, boron, iodine, copper, zinc, cobalt, molybdenum, manganese), acids, salts. Herewith concentration of some from these additives can amount several milligrammes. So, an actual task is an accurate batching of the components of nutrients. There are several variants of an equipment for the accurate batching of liquid solutions: valves with electric control for feeding of fuel in jet engines (they have high price because of utilization of expensive materials in their construction), hydraulic engines with periodic turns of executive element for angle less than 360o (don’t provide exact regulation of turning angle) and linear electric-hydraulic engines (have other designation and design that demands of improvement). Authors propose a scheme of improved apparatus for accurate batching of the components of nutrients hydroponic installations, created at the base of the linear electric-hydraulic engine. The apparatus has a simple and reliable design and provides a possibility of high accurate batching of the components of nutrients. There are cited equations and formulas for definition of main working parameters of the apparatus, that can be used for creation of its method of design calculation.
SIMULATION OF FATIGUE CRACK GROWTH DURING TRANSVERSE VIBRATIONS OF A TURBINE SHAFT
Authors: Bovsunovsky Anatoliy , Nosal Oleksandr
Published: June 2022

In real operational conditions structural elements of steam turbines are subjected to a wide range of thermal and mechanical loading. Even substantial reserve of static and dynamic strength, laid down at the stage of turbine design, can not prevent the appearance of fatigue cracks in structural elements, which lead to catastrophic failures. One of the reasons of damage in structural elements of turbine is technological operations used in the process of manufacture (forging, turning, and milling, heat treatment), since they are accompanied with plastic deformation of material, which is the physical basis of the so-called distributed fatigue damage. It accumulates during long-term cyclic deformation and turns into local damage of a fatigue crack type. In addition, the appearance of cracks in turbine shafts is caused by complex geometry, that is, by the presence of fillets and grooves, which are stress concentrators and, therefore, potential areas of initiation and growth of fatigue cracks. The high pressure rotor of the K-200-130 steam turbine was used to simulate the process of crack growth at forced transverse vibrations of the rotor when it passes through the first critical speed. At this the amplitude-dependent energy dissipation typical for metallic materials was taken into account. There was estimated the maximum stresses arising in the rotor when it passed through the critical speed rotation and the number of loading cycles leading to the crack growth. It was assumed that a crack with a depth of about 1 mm has formed on the surface of the rotor, which is the maximum permissible depth according to the instructions for safe operation of the turbine. The growth rate of this crack is predicted based on the fracture mechanics approaches through the determined maximum stresses in the section with a crack and experimental dependences of the crack growth rate on the stress intensity factor range. Based on the model, the crack growth time is predicted until the rotor loses its bearing ability. Predictions are made for different scenarios of loading and mechanical properties of rotor steel.
Economic Policy Uncertainty and Tourism Demand of OECD Countries in Mexico
Authors: Navarro-Chávez José César Lenin , Gómez Mario , Marín-Leyva René Augusto
Published: June 2022

This article analyzes the effects of economic policy uncertainty (EPU) on tourism demand from the top nine OECD countries in Mexico during 2010–2018. The research studies two groups of economies: developed and emerging economies. Using panel data, the results show evidence of
transversal dependence in income, exchange rate, EPU, and tourism arrivals. These variables are integrated of order one. In addition, there is a long-run equilibrium relationship among these variables. The group of developed countries show evidence of a negative relationship between tourism
demand and EPU, implying that a higher level of uncertainty leads to a decline in tourism demand. However, in emerging economies this relationship is positive. In addition, results suggest a positive relationship of both income and exchange rate to tourism demand, which implies that a higher
level of income in the OECD countries and a depreciation of the Mexican exchange rate might generate greater tourism demand in Mexico. In terms of short- and long-term causality relationship, evidence indicates that exchange rate, income, and EPU contain important information that contribute
to forecast the behavior of tourism demand in Mexico.

Authors: Prima Maya Sari  , Yunanda Rizka
Published: June 2022

Introduction: Glaucoma is the second leading cause of blindness for over 70 million people worldwide. Bilateral blindness occurs with an estimated 10%. In Indonesia, the prevalence of glaucoma is 0,46%. That means that 4 to 5 out of 1.000 people suffer from glaucoma. Considering glaucoma as the second cause of blindness after cataracts in the world and its irreversible nature, this study was conducted to determine the characteristics of patients with primary glaucoma in the Glaucoma Clinic, Dr. Mohammad Hoesin General Hospital in 2021 based on age, gender, diagnosis, and intraocular pressure.

Methods: This research is a descriptive retrospective study using secondary data through the medical record of patients in the Glaucoma Clinic, Dr. Mohammad Hoesin General Hospital Palembang from January to December 2021. The sample of this study was 20 people, and there were 40 eyes diagnosed with primary glaucoma.

Results: The number of Primary Glaucoma patients was more in female patients, namely 11 patients (55,0%) with age varies at ≤ 50 years of age (45,0%), namely 51-60 patients (35,0%) and aged ≥ 61 years as many as 4 patients (25%), with an age range from 40 years to 70 years. Most patients were POAG (85%), with the highest eye pressure was 38,8mmHg, and 43,4 mmHg in PACG.

Conclusion: There were 20 cases of primary glaucoma at the Glaucoma Clinic of Dr. Mohammad Hoesin General Hospital Palembang in 2021 with 40 affected eyes. Most patients were female, with most age group <50 years, and the most common type of glaucoma was open-angle.

Published: June 2022

This article aims to identify solid waste management in the urban district of Bantè in order to achieve a more effective and sustainable intervention highlighting a practical environment. Indeed, waste is evacuated all over this district. This practice leads to the proliferation of wild dumps, which pose aesthetic, environmental, and health risks. The method adopted was a cross-sectional one with a descriptive and analytical focus. A total of 236 households were interviewed, and 93 of them were selected according to the average daily waste production per household and per sector for the characterization campaign. The weight of waste to be sorted is defined according to the standard recommended by MEDECOM. Excel software was used for data processing and Arc-View software was used to produce the maps. The results showed that households produce an average of 0.22 kg/inhabitant per day in the urban district of Bantè. The most important categories of their waste are in order of importance: extra-fine, fine, putrescible, and plastics. Pre-collection by voluntary collection is the most suitable means with 92% of households. Heaps of rubbish are erected and proliferate the neighbourhoods. The most exploited disposal sites are empty spaces (58.47%), backwaters (20.23%), and concession yards (17.17%). Recovery is very little developed and is limited to reuse in households and summary recycling in workshops. From these results, the implementation of a waste management policy mainly based on the waste recovery into renewable energy, composting, and biochar would be an asset for the research district

Authors: Njuguna Mwaura J. , Muriuki Mary , Karenga Samuel
Published: June 2022

ATR-FTIR analysis is a robust method that is used to analyse solids and liquid samples with minimal sample preparation. The samples are usually placed on the ATR crystals and pressure applied to obtain a clear spectrum. Essential oils from O. kenyense were extracted through hydro distillation using the Clavenger apparatus for 8 hours. The essential oils were dried by passing through anhydrous sodium sulphate after which they were placed in brown viols and refrigerated at 4℃. The sample of oils was latter analysed at the government chemist in Nairobi County in Kenya. Compounds that recorded a high hit quality of 600 and above had the highest probability of being present in the oil. Eucalyptus oil had a hit quality of 673 and 1, 8-cionele had a hit quality of 655 respectively. Therefore, the two were presumed to be present in O. kenyense essential oils
Can meditation-based approaches improve the cleansing power of the glymphatic system?
Authors: Wostyn Peter , Goddaer Piet
Published: June 2022

The glymphatic system, first described in 2012, is a brain-wide perivascular network that plays an important role in promoting interstitial metabolic waste removal from the brain. Glymphatic pathway function has been reported to be dramatically diminished in the aging brain. Furthermore, glymphatic system dysfunction has been linked to a spectrum of neurodegenerative diseases including Alzheimer’s disease (AD). This waste clearance pathway of the brain is most active during sleep and is largely disengaged during wakefulness. While norepinephrine (NE) is responsible for suppressing the glymphatic function, electroencephalographic slow-wave (delta) activity has a facilitating effect. An intriguing question is whether these regulators of glymphatic activity can be modulated by meditation-based approaches and whether such approaches have the ability to increase glymphatic function in the awake brain. The present article hypothesizes that meditation-based approaches, such as immersive sound meditation, may have the potential to enhance glymphatic pathway transport and solute clearance by reducing NE and increasing slow-wave activity. If confirmed, meditation could be an attractive approach to promoting healthy brain aging and to preventing neurodegenerative conditions like AD.

Macro-engineering Design for an Artificial Lake in Southeastern Jordan
Authors: Al-Habahbeh Osama M. , Al-Adwan Romil S. , Al-Khawaldeh Mustafa A.
Published: June 2022

Water situation in Jordan has become very critical. A feasible solution is to desalinate water drawn from Gulf of Aqaba (GoA). Another problem that Jordan faces is the very short coastline. These two problems can be solved by developing an artificial lake in south Jordan. The water from the lake can be desalinated while the lake itself provides a badly needed coastline. This work presents a macro-engineering design for the proposed lake; The proposed project is named "Red Sea-Jafer Basin Conduit (RSJBC)"; it involves a pipeline connecting GoA at the Red Sea with Jafer Basin (JB) in the south-eastern desert, where the topography of the region is exploited to develop an artificial Lake. Using multiple pumping stations, seawater will be pumped from GoA to JB though a 220 km long pipeline. After constructing the project, it will take three years to fill-up the Lake. Once it is filled, the pumping rate is reduced from 51 to 30 m3/s. However, based on fresh water needs, a volume of up to 21 m3/s can be desalinated. The suggested pipeline route has a curved path (CP) to avoid the mountains if it were to go straight path (SP). A comparison is conducted between CP and SP, where it was found that CP offers the lowest development cost for RSJBC, given fabric pipe is used. More specifically, a pipe diameter of 6 m enables total development cost of 2.74 B$, with corresponding annual operating cost of 306 M$.
Energy Efficient Routing Design for Target Tracking in Wireless Sensor Network
Authors: Lokesh Deepika , Uma Reddy N. V.
Published: June 2022

The wireless sensor networks (WSNs) provides an advance way for connection of various applications. Most of the applications use the wireless sensor network to transmit the information from the device to the main base station. The main operation of the wireless sensor network is to first sense the data using the sensor, then collect the data and finally transmit to the required base station. The data is transmitted in a timely manner such that the other wireless sensor network transmitting the information should not have any problem. During the transmission of the data the main objective of the wireless sensor network device is to provide reliability to the information which is being sent with less latency and to reduce the energy consumption in order to increase the lifespan of the wireless sensor network. Therefore, this paper presents an Energy Efficient Routing for the Target Tracking (EER-TT) in the wireless sensor network which provides reliability, less latency and reduces the energy consumption during the transmission of the information to the base station. Proposed model also provides a cluster selection method for the routing of the wireless sensor network devices. The results attained show that our model EER-TT shows better results when compared with the existing routing-based models.

Animacy enhances recollection but not familiarity: Convergent evidence from the remember-know-guess paradigm and the process-dissociation procedure
Authors: Komar Gesa Fee , Mieth Laura , Buchner Axel , Bell Raoul
Published: June 2022

Words representing living beings are better remembered than words representing nonliving objects, a robust finding called the animacy effect. Considering the postulated evolutionary-adaptive significance of this effect, the animate words’ memory advantage should not only affect the quantity but also the quality of remembering. To test this assumption, we compared the quality of recognition memory between animate and inanimate words. The remember-know-guess paradigm (Experiment 1) and the process-dissociation procedure (Experiment 2) were used to assess both subjective and objective aspects of remembering. Based on proximate accounts of the animacy effect that focus on elaborative encoding and attention, animacy is expected to selectively enhance detailed recollection but not the acontextual feeling of familiarity. Multinomial processing-tree models were applied to disentangle recollection, familiarity, and different types of guessing processes. Results obtained from the remember-know-guess paradigm and the process-dissociation procedure convergently show that animacy selectively enhances recollection but does not affect familiarity. In both experiments, guessing processes were unaffected by the words’ animacy status. Animacy thus not only enhances the quantity but also affects the quality of remembering: The effect is primarily driven by recollection. The results support the richness-of-encoding account and the attentional account of the animacy effect on memory.

Aunque existe controversia sobre su adecuada denominación debido a sus características histopatológicas, la HLSIA puede ser causa de arritmias cardíacas, síndrome de vena cava superior, o diagnosticarse erróneamente como tumor maligno. Usualmente es un hallazgo incidental, de evolución asintomática y de buen pronóstico.
„I am not, of course, an Arab“ (Vulnerability and Secret in Mohsin Hamid’s The Reluctant Fundamentalist and Exit West)
Authors: Kostova-Panayotova Magdalena
Published: June 2022

The article studies two novels by the English writer from Pakistan, Mohsin Hamid, The Reluctant Fundamentalist (2007) and Exit: West 2017, which earned him world fame with the uncomfortable questions posed by exposing the hidden dangers in our globalized world. The books appeal for people to be more tolerant in order to achieve true human oneness. In these two novels, the writer depicts how fear of the Other can be the leading emotion of entire societies; it tells the story of a world in which no one and nowhere can feel safe and secure. Although Mohsin Hamid's characters are constantly fleeing because they can't find their home anywhere, they always seem to be trapped in time because something dramatic and violent is happening everywhere and it prevents them from settling, home is not just a fixed place but it is also a place where major events do not take place. Through complex, nostalgic and ambiguous images, Hamid sees fixation on grief and loss as a chasm between cultures. Both novels deconstruct racial and cultural codifications, presenting migrants as individuals with different personalities and traits, rather than as representatives of a particular religious or political group.

The Unknown Labour Camp in Slivnitsa (August – September 1989)
Authors: Zafer Zeynep
Published: June 2022

The labour camp in the military unit in the town of Slivnitsa as a place of state repression in the campaign for forced name change has not been the subject of special scientific research. In early 1985, hundreds of Turks from North-Eastern Bulgaria were summoned to the military checkpoints and as "mobilized" were sent to the unit, part of which was turned into a special labour camp. In Slivnitsa and other labour camps, the mobilized were subjected to heavy physical labour and psychological harassment. In the archive of the State Security documents are kept with some of the statistics on this form of violent dealing with the most active Turks – potential opponents of the forced name change and organizers of mass protests in North - Eastern Bulgaria. The repression in the labour camp in Slivnitsa from August-September 1989, happened during a period of the hardest field work for the tobacco producers. As "reserve troops" some of the most prominent Pomaks in Southern Bulgaria, including also some Turks from the Pazardzhik and Gotzedelchevski villages, were isolated. Subjected to humiliation, harassment and ideological manipulation, more than 100 people in a month were held halfhungry and forced to engage in heavy physical labour. This state violence scared the population and interrupted all possibilities for general opposition against the communist regime. This study aims to present this form of mass repression, carried out secretly and thoroughly concealed by the communist totalitarian regime in Bulgaria and plunged into oblivion. It is based on archival documents, memories, unknown to science notes and a list of the names of those brought in in 1989 in the labour camp in Slivnitsa.
Ethnography, Demography and Assimilation – How Talysh Community was Made to Disappear in Soviet Azerbaijan
Authors: Angelova Milena
Published: June 2022

The article explores one of the examples of assimilatory politics to the national minorities in Soviet Azerbaijan, and in particular to the Talysh community. In the 1930s, Talish were the fifth largest national minority in the country. The Talysh nationality erased from Soviet census categorization in 1959. Data from this census were used to support the decade-long political myth of "voluntary assimilation" of the Talish. The article also presents the instrumentalization of political manipulations in scientific discourses - Talysh minority were also recategorized by the ethnographers who consulted on census design and supported these government politics until 1989.
Women, CBAGs, and the Politics of Security Supply & Demand in Côte d’Ivoire
Authors: Bado Arsène Brice , Kendhammer Brandon
Published: June 2022

This study explores the drivers of participation and the roles women play within their communities in participating both formally and informally in community-based security groups. It seeks to understand how women are involved in community-based security groups by investigating and illustrating, among other things, their motivations and roles, the context, and the dynamics that underpin their participation in both the supply side and demand side of security provision. Based on extensive field research and an original dataset of interviews with a wide range of informal security actors, this research report offers two key findings to inform the work of policymakers and practitioners interested in security provision and peacebuilding. First, while women continue to engage directly and indirectly with community-based armed and informal security groups with a wide range of motivations, their overall place in the landscape of these groups is in flux, and those who participate bear social costs for doing so. Second, women’s influence in shaping the trajectory of community-based armed and security proving groups extends not just to their roles as suppliers of security (or insecurity, in the case of some groups), but as demanders of security. These complex dynamics point to the fact that women’s roles as participants, organizers, and mobilizers/legitimizers in CBAGs in ostensibly post-conflict settings like Côte d’Ivoire are no less complex than in overt conflict settings.

The postmodernist material cause of the schema of Crossbones implies an innovative method and a meta-cognition realm within postcolonial system of proposition and metadata, involves a new approach of intellection in the perspective relational values and relational frame theory stand as a dimensionality of understanding and a generative and transformative reality. Through an object program and a normative functionalism, Farah installs a psycho-functionalist perspective in the run to transcend the realm of ethnocentrism and relegio-politico social theory concerning the domain of formal conception and perception of relationalism. This persistence relates to an alternative understanding, a modality and property differentiation concerning the relational aesthetic and the status quo of the Be-ing, and a transformative reform about human intellect prerequisites and requests. in this dynamic of social practice and evidence-based practice, the relational aesthetic theory within Farah evolves his docufiction, define a method of linguistic performance and a relational expression that focuses on a conceivable representation of truth and experience.

The issues of Indonesian migrant workers are interminable; practically all bordering countries, including Malaysia, are destinations for Indonesian migrant workers. Administrative issues, salary disparities, exploitation, and human trafficking are all issues that Indonesian migrant workers encounter abroad. As the country's representative, the Embassy/Consulate General of the Republic of Indonesia plays a vital role in defending Indonesian migrant workers and Indonesian nationals overseas. The government's legal protection normally begins with document registration, followed by preparation, training, and placement. This study used a normative strategy with a statutory and case approach. Preventive protection takes the form of providing protection based on Law Number 21 of 2007 about TIP, Law Number 18 of 2017 concerning PMI Protection, and Malaysian Law in Deed 670 concerning the Anti-Trafficking in Persons and Anti-Migrant Smuggling Deed 2007. The Consulate General of the Republic of Indonesia Malaysia provides legal protection for Indonesian employees who are victims of illegal acts of human trafficking through both litigation and non-litigation routes.

With the increasing complexity of programs comes an increased focus on ensuring the quality of these programs. Essentially, it depends on improving the methods of testing the quality of these programs in the two phases of building these programs and after their operation. Therefore, we are developing software testing methods and methodologies. This paper aims to discuss software testing methods and their classifications according to their main properties and any software that suits each method. The majority of the literature on software testing methods and techniques is also included.
Magneto Thermosolutal Convection in a Compressible Viscoelastic Fluid
Authors: Kumar Pardeep
Published: June 2022

In the presence of a magnetic field, a thermosolutal convection is postulated to occur in a compressible Rivlin-Ericksen viscoelastic fluid in a porous media. The dispersion relation is found by using the linear stability theory and the normal mode analysis approach, respectively. In the scenario of stationary convection, it was discovered that compressibility, magnetic fields, and steady solute gradients all serve to delay the beginning of the convection process, but medium permeability serves to speed up the beginning of the convection process. In addition to this, it has been discovered that the system is reliable for [equation not detected by OJS] and under the condition  [equation not detected by OJS]. The system goes into an unstable state. Overstability has also been looked at from the perspective of a scenario in which sufficient circumstances are met to rule out the possibility of the phenomenon occurring. It has been discovered that the steady gradient of the solute and the magnetic field both induce oscillatory modes into the system.

In Twenty century, Partial Differential Equations (PDE) are solved by Numerical Approach such as Adam – Smith Methods, Numerical Simulation Methods, Finite Difference methods etc., In this article we discuss about difficulties of solve either Differential equations or PDE in 3 – Dimensional cases. So that we discuss only 1 – Dimensional Multigrid Methods (M. M) and we discuss about M. M.  Errors, Corrections, Type of grid such as Coarse Grid (C. G) and Fine Grid (F. G), Smoothing, non – smoothing approximation of C. G. Finally, we explain that M. G. M. works by decomposing problem into separate length scale and also using an iterative method. This method optimizes errors deduction in the length scales globally. In Multigrid Methods (MgM) several sub – routines must be developed to pass the data from C. G to F. G (Interpolation) from F. G to C. G (Reduction) and correction of the error at each grid interval (Smoothing), simply we have results reaction as (Reduction)C.G⇄F.G (Interpolation).

As a result of the COVID-19 epidemic, there has been an increase in the demand for electronic education apps in schools and colleges in recent years. The purpose of this paper is to develop an educational application for chemistry students at different levels of study that will allow them to obtain precise information on chemical substances in a timely and safe manner. This program uses a web scraping technique by applied a  RESRful API to extract information from websites, which is then sent to the student's account. Furthermore, due to the use of the Internet of Things, the application  has an anti-explosives and narcotics property using (IOT). The application can retrieve and save information entered by the user on chemical compounds with a high level of security. The medication's chemical formula, as well as the covalent and ionic bonding of compounds, can be displayed. It also has a database that lists all of the hazardous substances. If a user enters a dangerous compound containing narcotics more than four times, an alarm message is sent to the administrator via the Internet of Things.
Software requirements modeling from the selected set of requirements using fuzzy based approach
Authors: Arif Mohd , Mohammad Chaudhary Wali , Sadiq Mohd
Published: June 2022

Software requirements (SRs) modeling is one of the sub-processes of requirements engineering whose aim is to model and design the SRs before the development of a project. Different techniques are employed for representing the SRs using goal concepts, unified modeling language, etc. There could be a large number of SRs after the completion of the requirements elicitation process. It is not practical to model the complete set of the identified SRs because of the cost, time, and other limitations of an organization. There should be some systematic methodology to identify and select those SRs for modeling that need to be implemented during the software development process. The selection of SRs from the list of the elicited requirements is a multi-criteria decision-making process. In this process different stakeholders participate in the selection of the SRs. Linguistic variables may be used by the stakeholders to specify the preferences of SRs. To deal with this issue, a method has been proposed using a fuzzy based approach so that the selected set of SRs can be modeled and implemented during the development phase. The proposed method is explained by considering the small and large set of SRs for an institute examination system. The ranking value of the functional requirements of an examination system is computed. Based on the ranking order, top three requirements are modeled using use-case diagrams (UCDs) and class diagrams. It is found that both diagrams represent different information about the requirements of an examination system and there is no overlap in the information captured through UCDs and class diagrams.

Metodología para el análisis del comportamiento sísmico de grupos de pilotes
Authors: Ballesteros Granados Jeimmy Andrea
Published: June 2022

En el diseño de cimentaciones profundas como en pilotes de grupo, es importante realizar el análisis ante cargas laterales como las impuestas por los sismos, debido a que ante la ocurrencia de un sismo se presentan grandes fuerzas cortantes y momentos flectores a lo largo de los pilotes. Por tal razón, el diseño de grupos de pilotes sometidos a cargas sísmicas, está sujeto a diversas fuentes de incertidumbre, especialmente en lo que respecta al efecto de grupo; por tanto, resulta conveniente el uso de metodologías que tenga en cuenta la interacción suelo-pilote. Para avanzar en este objetivo, se presenta la metodología para el análisis del comportamiento sísmico en grupos de pilotes que se realizará para un sitio típico del Depósito Lacustre de la ciudad de Bogotá. En el presente artículo, se presenta la importancia de la temática mediante la recopilación de estudios previos respecto al análisis de grupos de pilotes sometidos a carga lateral, tanto a nivel internacional como a nivel regional; aspectos generales de la zona de estudio del proyecto; y, finalmente, se describe la metodología propuesta para un sitio típico del Depósito Lacustre de la ciudad de Bogotá.
