We explore the concept of abstraction as it is used in visualization, with the ultimate goal of understanding and formally defining it. Researchers so far have used the concept of abstraction largely by intuition without a precise meaning. This lack of specificity left questions on the characteristi...
object-oriented programming (programming) (OOP) The use of a class of programming languages and techniques based on the concept of an "object" which is a data structure (abstract data type) encapsulated with a set of routines, called "methods", which operate on the data. Operations on the ...
An abstract class is a blueprint for creating objects, but it cannot be instantiated on its own. Instead, abstract classes serve as a base from which other classes can inherit common properties and methods. This allows for a level of abstraction and provides a way to ensure consistency among ...
When code is executed in a VM, it is running on an emulated software environment rather than directly on the underlying hardware. VMs provide an additional layer of abstraction, enabling code to be platform-independent and facilitating portability. However, VM execution may introduce some performance...
Consequently, in 2012, NASA proposed a first framework of a DT for space missions, defining it as an ultra-realistic model of a physical asset that evolves alongside it, leveraging data from sensors integrated into the physical asset [28]. However, in the last year the concept of DT ...
The emergence of artificial intelligence (AI) and its progressively wider impact on many sectors requires an assessment of its effect on the achievement of the Sustainable Development Goals. Using a consensus-based expert elicitation process, we find that AI can enable the accomplishment of 134 targe...
To be truly considered "object oriented", a programming language should support at a minimum four characteristics: Encapsulation--implements information hiding and modularity (abstraction) Polymorphism--the same message sent to different objects results in behavior that's dependent on the nature of the...
Kerberos uses the concept of a time window in which its credentials are valid. It does not place restrictions on the clocks of the client or server. The client is required to determine the time bias between itself and the server and compensate for the difference by adjusting the window time...

Abstraction: Creating generalized models or representations of a problem or system, focusing on the essential details while ignoring unnecessary complexity. Abstraction helps in simplifying a problem and making it easier to solve. Algorithmic thinking: Developing step-by-step instructions or algorithms to...
