What is concept of dynamic?4 answersThe concept of dynamic encompasses various fields, such as heat transfer enhancement, creativity, and impression techniques. In the context of heat transfer enhancement, dynamic melting involves recirculating melted phase change material to improve effectiveness and reduce phase change duration. In the realm of creativity, dynamic creativity emphasizes the importance of time, change, and uncertainty in the creative process, shifting focus from products to processes. Additionally, in dentistry, a dynamic impression method captures functional movements of muscles, reducing random factors and improving the accuracy of special tray creation for prosthetics. These diverse applications highlight the dynamic nature of processes, whether in enhancing heat transfer, fostering creativity, or optimizing impression techniques in various fields.
Is dynamic pricing profitable?5 answersDynamic pricing has been shown to be profitable in various contexts. Research indicates that dynamic pricing, coupled with resource flexibility, can enhance profitability and service quality in field operations services. Additionally, optimal dynamic pricing strategies tailored to customer habits or satiation levels can maximize profits for firms. In the online information service sector, dynamic pricing mechanisms based on user feedback, service quality, and duration can lead to increased profits and consumer surplus. Moreover, in the sharing economy, dynamic pricing strategies have proven beneficial for both professional and nonprofessional hosts managing multiple listings, contributing to improved listing performance and revenue optimization. Therefore, the evidence suggests that when implemented effectively, dynamic pricing strategies can indeed be profitable across various industries and business models.
What are the limitations of dynamic capability theory?5 answersThe limitations of Dynamic Capability Theory include conceptual and operational challenges, as well as a lack of comprehensive frameworks and empirical evidence for causal inference. These limitations hinder the theory's full potential, requiring the development of theory-congruent proxies for key variables and addressing the plurality of concepts within the theory. Additionally, the lack of econometric evidence accounting for causal inferencing poses a significant challenge to the advancement of Dynamic Capability Theory. Overcoming these limitations is crucial for the theory to enhance its applicability and value, especially in understanding competitive advantage in dynamic environments and its relationship with various fields such as accounting, marketing, and business model innovation.
What is the dynamic assessment?5 answersDynamic assessment is an approach that combines instruction and assessment to measure students' learning potential and their response to specific interventions. It focuses on the process of learning and responding to interventions, rather than measuring prior learning or achievement. Dynamic assessment involves individualized interactions between test administrators and examinees, and can take different formats, such as interventions occurring between pre- and post-tests or during test administration based on examinee responses. It is rooted in Vygotsky's zone of proximal development, which emphasizes the gap between what learners can do independently and what they can do with assistance. Dynamic assessment has been applied in various domains, including education and psychology, and has shown promise in assessing multilingual individuals. Further research is needed to determine its utility in non-alphabetic languages.
What is dynamic viscosity?5 answersDynamic viscosity is an important parameter for quality control in industrial processes and the production of industrial substances. It refers to the resistance of a fluid to flow under an applied force or shear stress. Non-Newtonian viscosity behavior, which is the viscosity of heterogeneous mixtures and polymeric solutions, is particularly significant as it can affect a fluid's performance and cause handling and processing issues. Various methods have been developed to measure dynamic viscosity, including a novel process viscometer based on fluid dynamic measurement principles, a dynamic method using the angular acceleration of a probe immersed in a liquid sample, and a dynamic viscosity admeasuring apparatus with U-shaped viscometers and a negative pressure generator. The viscosity of a liquid lubricant can also be determined by obtaining the friction torque between two spherical surfaces. Overall, dynamic viscosity is a crucial property that plays a significant role in various industrial processes and material performance.
What are the principles of dynamic analysis?3 answersDynamic analysis involves inferring rules that govern the behavior of an unknown system based on a sample of observations. It is used in various domains such as engineering and software engineering. The principles of dynamic analysis include linking general principles to their applications from different angles, addressing topics such as statistics of motions and loading, damping modeling and measurement, nonlinear dynamics, fatigue assessment, vibration and buckling, structural health monitoring, human body vibrations, and vehicle-structure interactions. In the domain of software engineering, dynamic analysis aims to infer rules that govern the behavior of software systems from a sample of executions. However, deriving general rules from dynamic analysis is challenging due to incomplete input samples. Advances in grammar inference, a related field, have provided solutions for accurately inferring rules from sparse information, which can be applied to dynamic analysis problems.
