ⓘ Conceptual modelling ..


Acceptability is the characteristic of a thing being subject to acceptance for some purpose. A thing is acceptable if it is sufficient to serve the purpose for which it is provided, even if it is far less usable for this purpose than the ideal example. A thing is unacceptable if it deviates so far from the ideal that it is no longer sufficient to serve the desired purpose, or if it goes against that purpose. From a logical perspective, a thing can be said to be acceptable if it has no characteristics that make it unacceptable: We say that a theory Δ is acceptable if for any wff α, Δ does n ...


Analogy is a cognitive process of transferring information or meaning from a particular subject to another, or a linguistic expression corresponding to such a process. In a narrower sense, analogy is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction, in which at least one of the premises, or the conclusion, is general rather than particular in nature. The term analogy can also refer to the relation between the source and the target themselves, which is often a similarity, as in the biological notion of analogy. Analogy ...

Conceptual design

Conceptual design is an early phase of the design process, in which the broad outlines of function and form of something are articulated. It includes the design of interactions, experiences, processes, and strategies. It involves an understanding of peoples needs - and how to meet them with products, services, and processes. Common artifacts of conceptual design are concept sketches and models.

Conceptual framework

A conceptual framework is an analytical tool with several variations and contexts. It can be applied in different categories of work where an overall picture is needed. It is used to make conceptual distinctions and organize ideas. Strong conceptual frameworks capture something real and do this in a way that is easy to remember and apply. Isaiah Berlin used the metaphor of a "fox" and a "hedgehog" to make conceptual distinctions in how important philosophers and authors view the world. Berlin describes hedgehogs as those who use a single idea or organizing principle to view the world. Foxe ...

Conceptual programs in physics

For the simple case of single particle with mass m moving along one dimension x and acted upon by forces F i {\displaystyle F_{i}}, the program of classical mechanics is to determine the state x: R → R {\displaystyle x:\mathbb {R} \to \mathbb {R} } by solving Newtons second law, In Lagrangian mechanics for the same system, the state q: R → R 3 N {\the style property display set to \mathbf {U}:\mathbb {R} \to \mathbb {R} ^{3P}} solves Hamiltons principle δ S = 0 {\properties display style set to \Delta S=0} where the action functional is defined how S \ {\stackrel {\mathrm {def} }{=}}\int _ ...

Economic model

In economics, a model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. A model may have various exogenous variables, and those variables may change to create various responses by economic variables. Methodological uses of models include investigation, theorizing, and fitting theories to the world.

Pino - logical board game which is based on tactics and strategy. In general this is a remix of chess, checkers and corners. The game develops imagination, concentration, teaches how to solve tasks, plan their own actions and of course to think logically.
