Guidance on the Verification and Validation of Digital Twins
Authors: Vanderhorn Eric , Valluri Sharat
Published: April 2024

Digital twins are increasingly being used to address challenges and support decision-making in the offshore industry. Digital twins are defined here as a virtual representation of a physical asset, along with its environment and processes, comprised of integrated models that are updated through data exchange to provide decision-making support over its lifecycle. The developers and users of these digital twins, the decision makers using information obtained from the results of these digital twins, and the individuals affected by decisions based on such digital twins are focused on understanding if a digital twin and its results can be trusted. This concern can be mitigated through the appropriate application of verification and validation. Verification is typically defined as ensuring that the computerized model and its implementation are compliant with its requirements and specifications as detailed in its conceptual models, mathematical models, or other constructs (that is, “Did I build the thing right?”). Validation is defined as a process of determining the degree to which a digital twin is an accurate representation of the real world with respect to an intended use (“Did I build the right thing?”). This paper first establishes a modular and scalable ontology for digital twins that consolidates many existing definitions and descriptions into a format that is conducive to supporting verification and validation activities. Building on this ontology, two frameworks are presented: one framework for performing verification and validation on a developed digital twin and a separate framework for performing independent verification and validation on a third-party created digital twin. The goal of these frameworks is to define, determine, generate, and document the information needed to assess the digital twin’s credibility and justify using the digital twin for the specified use case or application. Additionally, considerations of related aspects, such as digital twin criticality, are also discussed.
Modeling Drop Weight Tear Test Procedure for X65 Q&T pipeline Steel Including Reverse Fracture
Authors: Sakonder Muhammet Cuneyt , Paredes Marcelo , Cristea  Mihaela E , Darcis Philippe
Published: April 2024

Abnormal fracture appearance (AFA) in drop weight tear tests (DWTT) is a significantly growing concern for pipe makers and customers, especially in next-generation high-strength pipeline steels where the likelihood of occurrence of such a phenomenon is high. Investigating and understanding this abnormality, from the engineering point of view, is essential for mitigating its occurrence warranting material quality, and ensuring safe operation of pipeline networks. In particular, AFA refers to unexpected and non-standard patterns of material fracture morphology during impact tests, i.e., the initial ductile crack propagation suddenly turns into a cleavage fracture as the propagating crack moves across the sample’s ligament. The statistical nature of this occurrence requires a deterministic approach to resolve it in the form of reducing its likelihood during experiments. In order to set a strategy to address this issue a phenomenological continuum level model is developed to consider the ductile-brittle transition (DBT) behavior of X65 Q&T as well as the strain rate effect which will provide a platform to study the recurrence of reverse fracture morphology.

Authors: Wu  Thomas S. , Kinnas  Spyros A.
Published: April 2024

The increasing demand for sustainable energy sources to mitigate climate change has grown interest in harnessing renewable energy from the oceans. Ocean current energy, characterized by its reliability and predictability, stands out as a promising solution for a sustainable future. In this study, a coupling model that combines the Reynolds-Averaged Navier-Stokes (RANS) method with a lifting line method with a fully aligned wake is presented and applied to the design of horizontal axis marine turbines, aiming to optimize power output efficiency in uniform flow by using various duct shapes. The RANS method is employed to simulate the flow around the duct, while the turbine blades are represented by a pressure distribution function based on the lifting line model. At the design phase, the turbine's power coefficient has been scrutinized to assess the influence of duct geometry on turbine performance. Subsequently, a comprehensive hydrodynamic analysis, using a boundary element method, applied on both the duct and the turbine, is conducted to validate the power coefficient and the loading distribution of the designed turbines. Our results show that significant gains in the power delivered by the turbine can be achieved by the presence of a properly designed duct.

In the complexity of education policy, it is really difficult to apply how allocate political resources – status, legitimacy, authority, power, interests – precisely. In other cases, it is actually very difficult to formulate the reality of socio-political problems in quantitative measures. Likewise with a number problematic political issues and problems faced will tend to be simplified to adapt to the wishes of the analyst and the quantitative methods used, so that This results in fundamental matters relating to the context of socio-political reality which is behavioral in nature and is considered not to be quantifiable, and tends to be ignored and cannot be described fully. The qualitative perspective of education policy is basically a process of understanding on policy problems so that they can give birth to ideas/thoughts regarding ways to solve them. The education policy problem itself is qualitative in nature so it is a process This understanding is also full of qualitative thinking. Understanding of educational policy problems are born from a deductive way of thinking, a way of thinking that starts from Theoretical insights are translated into more operational and operational conceptual units connected to reality. Theoretical insight itself does not stand alone because it is very depends on the subjectivity of an analyst in perspective on education policy. Differences in insight are not simply due to the nature and type of policy problem, however tends to be caused by different points of view or differences in thought paradigms or different philosophies of thought.

In the development of technology and information, developments in means of transportation cannot be separated, which as time changes, always offers the newest forms of technology, even in terms of vehicle design. In its current development, cars are a means of transportation that can be said to be owned by all groups. The need to have this means of transportation makes it possible for consumers who need a car as a means of transportation but it is not always available and accessible to the general public. Non-bank financial institutions exist as an effort to facilitate the community in meeting their needs. Credit is an alternative for the community as an alternative effort to meet existing needs. Fiduciary guarantees are regulated in Law Number 42 of 1999 in order to maintain security in the credit process and to become a credit object registered with the Fiduciary. In legal research, it is explained that the rights and obligations on the part of the consumer are to pay the consumer with the nominal value of the party making the sale and then take back the car as an object of consumer financing guarantee if in the future there is a default. If a default occurs, the buyer is obliged to provide compensation, namely canceling the agreement under compelling circumstances

Authors: Oudah Ishraq Ghaleb , Rajabi Reza
Published: April 2024

Fencing sport coaches seek fencers who have high velocity and work hard to develop it through training. The research problem lies on when measuring movement abilities through some tests. Manual measurement does not give reasonable impartiality of timing because there is a time-frame between the movement of the fencer and the speed of the movement of the human time setter. Therefore, the authors sought to design an electronic vest to evaluate movement abilities in foil fencers. The study design was experimental, with 12 Iranian foil fencers of the national team, who were divided into two equal groups of 6 fencers. Moreover, there were 12 students from Physical Education and Sport Sciences that worked on the scientific foundations to design the electronic vest. After conducting 4 exploration tests, the electronic vest proved its efficacy to evaluate movement abilities in foil fencers. In conclusion, the electronic vest designed in this study has high quality and accuracy to evaluate movement abilities in foil fencers.

The current study investigated how the traditional sport of Jianzi (also called shuttlecock) affects physical fitness and body functions. The experimental group (EG) conducted a 15-week experiment with the Shuttlecock Model Club (SMC), while the control group (CG) participated in the physical education (PE) program at An Giang University (AGU) as usual. Both groups comprised 60 normal healthy female students. To evaluate fitness, this study included five tests: the 30-second sit-up test, the 30-meter sprint test, the shuttle run test (4 x 10 meters), the long jump test, and the 5-minute running test to measure maximal aerobic rate (MAS). We used 10 tests to evaluate physiological functions of the body such as BMI; Body fat %; Chest skinfold (mm); Waist skinfold (mm); Thigh skinfold (mm); Diastolic pressure; Flexion angle of the hip joint; Resting heart rate; Systolic pressure; VO2max. Except for explosiveness and core strength of the legs, this study demonstrated that EG improved more than CG in speed, agility, and maximal aerobic speed after completing 15 weeks. The EG group exhibited the most significant improvement in fitness tests, with MAS increasing by 23.60% and speed by 1.03%. The control group improved at a low level with an increased rate of 0.99% in speed and 6.87% in MAS. For functional body tests, the EG group also showed significant improvement compared to the CG. The highest improvement (18.39%) was in the variable waist skinfold (mm) in the EG.

Authors: Elmahdy Menan A , Ayad Khaled , Metwally Abdelrahman Amira , Shawki Abdelsalam Mohammed
Published: April 2024

Background: Long distance runners commonly complain from patellofemoral pain syndrome (PFPS) that limits their performance and return to sport. Abnormal neuromuscular control of the quadriceps has been demonstrated to cause patellar mal-tracking and hence PFPS. Changes in muscle morphology and neural activity have a role in neuromuscular changes, a key contributor to either primary or secondary injuries. Poor landing mechanics, impaired postural control, as well as changed peripheral muscle activation are all clinical manifestations of neuromuscular control deficiencies caused by central nervous system defects that have a deleterious effect on the contractile characteristics of skeletal muscle. Objectives: The purpose of this study was to investigate the correlation between contractile properties of quadriceps muscle and functional performance in long distance runners with PFPS. Study design: Cross-sectional study. Methods: Thirty runners were recruited form multiple Egyptian clubs. Tensiomyography (TMG) Parameters were assessed regarding Contraction time (Tc), Maximal displacement (Dm), Sustain time (Ts), Relaxion time (Tr) and Delay time (Td) in Rectus femoris (RF), Vastus medialis (VM) and Vastus lateralis (VL) separately and correlated with functional performance; number of repetitions in 30 seconds for anteromedial lunge test, balance and reach test and step-down test. Outcome measures: Functional performance was measured using functional performance tests; anteromedial lunge test, balance and reach test and step-down test. Results: It was found that VM Tc, VL Dm, were moderately positively correlated with anteromedial lunge (r = 0.583, 0.404, p<0.05) respectively. In contrast, RF Tr was negatively correlated with anteromedial lunge (-0.364, p<0.05); VM Ts,Tr,Dm; VL Td were moderately negatively correlated with balance and reach (r = --0.577, -0.388, 0.655 and -0.385, respectively, p<0.05). In contrast, VL Tc was moderately positively correlated with step-down (r = 0.424, p = 0.019). Conclusion: All contractile properties of quadriceps muscle are significantly correlated with functional performance in long distance runners with PFPS. Future studies should address these properties, using proper rehabilitation strategies, to improve performance of runners with PFPS.

Authors: Benchamma Sofiane , Missoum Mohammed , Belkacem Nefissa
Published: April 2024

The focus of this study is to investigate the energy performance of a direct-expansion solar-assisted heat pump water heating system (DX-SAHPWH). The system consists of an unglazed solar collector-evaporator, which can absorb heat from solar energy and air ambient simultaneously, a condenser in the form of a coil immersed in a hot water storage tank, a thermostatic expansion valve and a hermetic reciprocating compressor. The performance of the heat pump system is evaluated using a developed mathematical model under Matlab code. The modelling method is based on lumped and distributed parameter approach of different system components. Numerical calculations were carried-out to study the influence of different parameters, such as ambient temperature, solar radiation intensity and polytropic index on the system performance. Additionally, in order to evaluate the long-term system performance, the system’s model was applied on a case study of a single-family building located in Djelfa (Algeria), which represents the coldest arid region of the country. The results showed that the solar radiation intensity and ambient temperature have significant effects on the heat pump performance. A COP of 5.9 and a collector-evaporator efficiency of 1.9 were obtained at high solar radiation of 850 W/m2 resulting in lower heating time (29 min). In addition, results revealed that the system can operate even at lower ambient temperature due to its ability to take advantage of heat from the ambient air. The results from the case study gave a COP ranging from 2.3 to 3.8, which enhance the promising adoption of this system in domestic hot water production to respond to people daily life needs with clean, abundant and renewable energy.

Published: April 2024

Due to ageing of seed over the time, seed losses its vigour and viability, which makes it unfit for sowing. So thestudy was conducted to check the efficacy of microwaves for seed treatment for seed quality enhancement. The objectiveof the study was to understand the effect of microwaves on physiological and biochemical attributes of seed quality of agedsorghum seeds. The sorghum seeds were subjected to ageing for 96 h of variety SPV-2217 to microwaves seed treatmentsof different intensities and time period i.e.30% intensity, 40% intensity and 50% intensity for 30 and 40 seconds whichwere compared with untreated control and seeds primed with CaCl2 (2% for 8 h). Data was analyzed using completelyrandomized design and randomized block design with three replications.Considering the seed quality parameters the highestmean germination (82.33%), shoot length (16.8 cm), root length (16.2 cm), vigour index I (2717) and least electricalconductivity (0.773 dSm-1) was noted in the seeds treated at 30% intensity for 40 seconds followed by the treatment 40%intensity for 30 seconds. The seedling dry weight (22.63 mg/seedling) and vigour index II (1848) was highest in thetreatment 30% intensity for 30 seconds. These seed quality parameters were supported by biochemical parameters inwhich the treatment 40% intensity for 30 seconds showed highest traits for catalase (6.542 μM of H2O2 decomposed/min/mg protein), peroxidase (0.0484 μM min/mg protein of tetraguaiacol formed) and superoxide dismutase (16.69 units/mgprotein), while alpha amylase was highest (0.611 μmol/min/mg protein) in 30% intensity for 30 seconds and proline(4.03 μM/g fresh weight) in 30% intensity for 40 seconds. The improvement of seed quality and biochemical parameters,ultimately resulted in better field parameters i.e. field emergence (81.33%), plant dry weight 30 days after sowing (20.32 g)and chlorophyll content (30.96 units) in the treatment 30% intensity for 30 seconds. While maximum plant height (71.5 cm)and number of leaves (5.0) in the treatment 40% intensity for 30 seconds. Decline was observed in all the parameters as theintensity and duration was increased beyond 40% intensity for 30 seconds. Hence, 30% intensity for 40 seconds was foundto be the most effective treatment along with 40% intensity for 30 seconds.

The experiment was conducted at the Department of Post Harvest Technology, KRC College of Horticulture,Arabhavi, Belagavi district, Karnataka, India during 2020-21 to find out the suitable packaging material for storage ofshatavari root powder in Factorial Completely Randomized Design with two factors (types of roots and packagingmaterials). Different packaging materials viz., aluminium pouch, polyethylene lined aluminium pouch and polypropylenepouch were used for packing of shatavari root powder. Magnesium silicate, an anticaking agent was used at 1.00 and 1.50per cent concentration to avoid the caking of powder and vacuum packaging were also tried for these different packagingmaterials for storage of shatavari root powder without anticaking agent. The minimum moisture content (7.64%), wateractivity (0.550), L value (63.76) was noticed in yellow roots after three months of storage whereas maximum moisturecontent (8.10%), water activity (0.561) and L value (67.68) was observed in white root after three months of storage.Shatavari powder packed in polyethylene lined aluminium (laminated) pouch with vacuum recorded lower moisture content(6.25%), water activity (0.416), a* value (2.72), maximum L value (72.33) and b* value (19.82) followed by polyethylenelined aluminium pouch with 1.5 per cent magnesium silicate. The polyethylene lined aluminium pouch with vacuumcondition or 1.5 per cent magnesium silicate proved better for storage of shatavari root powder.

Revenue Models of Academic Enterprises – An Empirical Study in Vietnam
Authors: Quyet Chu Ba , Minh Nguyen Binh , Hoai Le Thi
Published: April 2024

Academic publishing is the publishing field associated with scientific works, scientific articles, or scientific documents. Under the impact of the Internet, digital transformation, and open access, academic publishing is also affected. Academic publishers around the world have changed their revenue models to grow but this creates controversial views. In Vietnam, academic publishing is developing in response to internal needs and international integration. Academic publishers and scientific journals in Vietnam are also influenced by digital transformation and open access. Besides the opportunities, the challenges facing the academic publishing sector in Vietnam are research quality and revenue model. Based on the content research method, this writing presented some basic theories about academic publishing, academic publishing revenue models, and some discussions about academic publishing in Vietnam.
Solving a Predictive Model of Infectious Disease in Epidemiology and Epizootiology by Assigning Scores to Individuals
Authors: Kremeň Jozef , Korim Peter , Nagyová Alena , Dvorská Oľga , Takáčová Daniela , Vargová Mária , Ondrejková Anna , Prokeš Marián , Zigo František
Published: April 2024

Every mathematical solution to a problem corresponds to a model that more or less corresponds to reality. One of the many possibilities is the solution to epidemiological problems (processes) using the susceptible-infected-removed (SIR) model. Like any model, this model also has its advantages and benefits that allow us to close such a complicated reality as the origin and course of the epidemic into simple differential equations (DE) and through the model’s parameters modify it and compare it with reality. This is possible only in the case of a comprehensive understanding of reality in all its breadth and depth. This study focuses on another solution to the epidemiological or epizootiological processes based on the newly designed simulation, which assigns individuals a certain score in time intervals. In this case, the score from the simulation has a normal probability distribution with certain parameters N (µ, σ) in given time intervals. This score level also divides the given individuals into certain groups based on the given (selected) critical level. This determines whether individuals are with manifestations of the disease or without signs of the disease. In the study, the epidemic curve (EC) simulation results could be used to solve the current pandemic caused by COVID-19. It can be stated that the newly proposed model could be more suitable because it permanently confirms the agreement of experimental and expected frequencies.

Research on Color Attention Bias Caused by Olfactory Stimulation in Visual Search Task
Authors: Bai Hexin , Zhang Haibin
Published: April 2024

People often connect and integrate information from different sensory channels to form cross-channel connection. Previous studies have proved that vision, as a dominant perception, will affect the perception and recognition of olfactory channels. This study attempts to prove experimentally that olfactory channels have an influence on the perception and recognition of visual information. Experimental method: Subjects were asked to search the target with a specific shape visually after deeply smelling fragrance card, and their respective reaction time was tested. The indicative of olfactory stimuli is regarded as an intragroup variable, and the forward and reverse correlation between target color and olfactory stimuli is regarded as an inter-group variable. The experimental results show that when the color associated with olfactory stimulation appears on the target pattern, it will speed up the visual search, but when the color associated with olfactory stimulation appears on the interference pattern, it will hinder the visual search speed. Conclusion: It is proved that olfactory cues will lead to visual attention bias to its associated colors, indicating that there is a cross-channel influence of olfactory stimuli on visual attention.

Navigating the Impact: Turkey's Foreign Policy Post-2018 US Sanctions on Iran
Authors: Heryandi Melinda Aindya , Sinulingga Anita Afriani , Jamilah Maryam
Published: April 2024

As a strong ally of the US, Turkey was subject to economic penalties in May 2018 for its continued imports of Iranian oil. Turkey delayed deciding whether to import Iranian oil despite this pressure. The purpose of this study is to examine Turkey's foreign policy about the importation of Iranian oil in 2018. The study uses a qualitative method with an explanatory analysis approach, drawing on the foreign policy theories of Morgan and Palmer, which highlight the objectives of proaction and security. The results show that Turkey's foreign policy goals are more proactive due to two major variables. First, Turkey and the United States do not work together well. Second, Turkey's proaction-oriented foreign policy is influenced by its capabilities, which include military might, alternative alliances, influence both regionally and internationally, and bargaining power. Turkey forms new alliances with Iran, China, and Russia, primarily concentrating on deepening its relationship with Russia. Furthermore, Turkey has a great deal of regional and global influence, as seen by its mediating role in the Syrian Israeli crisis in 2011. Turkey's foreign policy dynamics are further emphasized by its negotiating stance with the United States over the Incirlik zone. In conclusion, Turkey's strategic negotiating positions, alliance preferences, and regional and global capacities all influence its complex foreign policy strategy.
