How to make theoretical lens? 


Best insight from top research papers

Theoretical lenses can be made by using different approaches. One approach is to use theories as analysis foci, where theories are used as starting points to identify gameplay design patterns . Another approach is to distill patterns from theories, where patterns are extracted from theories to identify design patterns in gameplay . Additionally, theories can be used to understand the consequences of having or not having patterns present in a game design . In the field of optics, theoretical lenses can be designed by studying different schemes such as the RADANT phase scanning scheme and the transmission-type loaded line phase shifter scheme . These schemes can be used to design electronic beam steering RADANT lenses . Furthermore, lenses can be designed based on Mie resonances in cylinders with positive permittivity and permeability . The design of lenses can be further improved by considering the microstructure of the material .

Theoretical reviews are essential for enhancing decision-making processes, enriching the field of marketing, and improving the quality of services in various sectors, such as healthcare and online businesses.
What is theoretical framework?4 answersA theoretical framework is the foundation and theoretical support of an investigation. It is essential in quantitative research to analyze and systematize information. The construction of a theoretical framework involves identifying the problem and variables, gathering information from reliable databases, and avoiding thematic dispersion unrelated to the variables. Theories in behavioral research are often developed at a granular level, tied to specific independent variables or moderating variables. To overcome this limitation, integrative theoretical frameworks are needed to provide a broader understanding of why effects occur. The Ambiguity-Adoptability-Accessibility (3A) framework is an example of such a framework that enhances the explanation of different effect paradigms. Theoretical frameworks in waste studies combine concepts from ecological economics, political ecology, and waste management to understand the relationship between the environment, economy, and power relations. They introduce new concepts like capital accumulation by contamination to explain social metabolism changes. In the study of Khomeini's discourse, a theoretical framework combining Critical Discourse Analysis (CDA) and Critical Metaphor Analysis (CMT) is used to analyze the political aspects of language. Theoretical and conceptual frameworks are lenses through which scholars view research design, guiding the entire approach and connecting to methodological approaches, data collection, analysis, and trustworthiness.
How to do theoretical framework?5 answersTo construct a theoretical framework, it is essential to identify the problem and variables, and gather information from reliable databases. It is important to avoid thematic dispersion unrelated to the variables. The construction process can be divided into 8 methodical steps, which involve functions, levels of abstraction, and the identification of errors that may occur during development. In the field of theoretical morphology, different classifications of morphological theories exist, such as Item-and-Arrangement, Item-and-Process, and Word-and-Paradigm models. Implicative relations can be formulated in various ways, including generalizations on exponents, stems, or inflected wordforms. Theorizing with greater explanatory scope is needed to overcome the obstacle of conducting research within silos of effect paradigms. Integrative theoretical frameworks, such as the Ambiguity-Adoptability-Accessibility (3A) framework, can enhance the explanation of different effect paradigms and improve the applicability of behavioral research. The theoretical framework of the private peace entrepreneur phenomenon includes a typology of PPEs, their impact on the official diplomatic sphere, and an analytical framework that distinguishes among variables. The conceptual framework for healthcare reforms considers the legal and political context, the sociology of professions, and the interactive dynamics between government and the medical profession.
How to create an theoretical framework?3 answersCreating a theoretical framework involves several steps. First, it is important to define the central territory of examination for the discipline and offer possible definitions for the lexical register of the field. Next, suitable epistemological approaches should be considered for constructing the framework. The framework should be based on relevant theories and models that provide a foundation for understanding the phenomenon being studied. For example, in the context of layoff agents, a theoretical framework can be developed to understand their cognitions and perceptions related to organizational downsizing. Similarly, in the context of electoral competition, a theoretical framework can be built based on models that analyze the interaction between political parties and voters. Additionally, the framework should incorporate relevant concepts and perspectives that capture the unique experiences and perspectives of specific groups, such as African female entrepreneurs. By integrating different theories, models, and perspectives, a comprehensive theoretical framework can be created to guide research and analysis in a specific field or discipline.
What is a theoretical framework?5 answersA theoretical framework is a structure that guides and supports research work. It helps researchers in formulating research questions, maintaining focus, and interpreting results. The framework provides a basis for conducting the study, prevents errors and plagiarism, and keeps the researcher updated on the subject and relevant documents. It serves as a reference point for understanding how the study will be carried out.

Isotope effect in Kirkendall effect
5 answers
The Kirkendall effect, typically associated with atomic diffusion imbalances in materials, does not directly involve an isotope effect based on the provided contexts. The Kirkendall effect primarily focuses on the migration of different atoms at varying rates during diffusion processes within alloys or nanoparticles. While the Kirkendall effect is extensively studied for its role in creating hollow nanocrystals and facilitating heavy metal removal in wastewater treatment, the concept does not specifically address the isotope effect. The phenomenon of Kirkendall effect is mainly explained through mechanisms like vacancy generation and annihilation, without direct reference to isotopic differences in diffusion rates. Therefore, the isotope effect is not a central aspect of the Kirkendall effect as described in the provided research contexts.
What is the antenna array for patch antenna?
5 answers
The antenna array for a patch antenna can vary based on the specific design requirements and applications. One approach involves utilizing a waveguide-fed traveling-wave array designed using the Haar function series and a genetic algorithm, achieving broadside radiation at 9.5 GHz with a gain of 17.6dB and 17.7dB, and side lobe levels of -22.5dB and -21dB in H-plane and E-plane, respectively.

Additionally, a low-profile, broadband microstrip PCB antenna with a double U-slot design can achieve triple-band resonant modes and improved performance by incorporating a gap in the ground plane.
How does the choice of antenna elements and spacing affect the performance of an array antenna topology in GNSS?
4 answers
The choice of antenna elements and spacing significantly impacts the performance of array antennas in GNSS applications. Different configurations, such as virtual arrays with adaptive spacing, ring antenna arrays, and compact four-element arrays with high isolation levels, offer unique advantages. For instance, adaptive spacing can enhance anti-jamming performance without increasing the footprint or number of elements. Ring antenna arrays provide invariance to the main lobe direction, improving accuracy in measuring navigation parameters. Compact arrays with high isolation levels cover multiple GNSS bands effectively. These variations in antenna elements and spacing influence directivity, radiation pattern control, beam scanning capabilities, and overall performance of array antennas in GNSS applications.
