Topic 9: Swarm intelligence
Swarm intelligence (SI) is a type of artificial intelligence based on the collective behavior of decentralized, self-organized systems. The expression was introduced by Gerardo Beni and Jing Wang in 1989, in the context of cellular robotic systems.

Topic 8: Bottom-Up
Top-down and bottom-up are strategies of information processing and knowledge ordering, mostly involving software, but also other humanistic and scientific theories (see systemics). In practice, they can be seen as a style of thinking and teaching. In many cases top-down is used as a synonym of analysis or decomposition, and bottom-up of synthesis.
Topic 7: Emergent Behavior
An emergent behavior or emergent property can appear when a number of simple entities (agents) operate in an environment, forming more complex behaviors as a collective. If emergence happens over disparate size scales, then the reason is usually a causal relation across different scales. In other words there is often a form of top-down feedback in systems with emergent properties.

Topic 6: Super cilia skin
Super Cilia Skin is a literal membrane separating a
computer from its environment. Like our skin, it is
haptic I/O membrane that can sense and simulate
movement and wind flow. Our intention is to have it
be universally applied to sheath any surface. As a
display, it can mimic another person�s gesture over a
distance via a form of tangible telepresence. A
hand-sized interface covered with Super Cilia Skin
would produce subtle changes in surface texture that
feel much like a telepresent "butterfly kiss."
Topic 5: CATIA
CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systemes and marketed worldwide by IBM. Written in the C++ programming language, CATIA is the cornerstone of the Dassault Systemes product lifecycle management software suite.
Topic 4: Render
Rendering is the process of generating an image from a model, by means of computer programs. The model is a description of three-dimensional objects in a strictly defined language or data structure. It would contain geometry, viewpoint, texture, lighting, and shading information. The image is a digital image or raster graphics image. The term may be by analogy with an "artist's rendering" of a scene. 'Rendering' is also used to describe the process of calculating effects in a video editing file to produce final video output.

Topic 3: Virtual.
The term virtual is a concept applied in many fields with somewhat differing connotations, and also, differing denotations.
The term has been defined in philosophy as "that which is not real" but may display the salient qualities of the real.[citation needed] Colloquially, 'virtual' is used to mean almost, particularly when used in the adverbial form e.g., "That's virtually [almost] impossible".
...
The word virtual has been applied to computing and information technology with various meanings. It is used of software systems that act as if they were hardware systems[citation needed] (virtual machine, virtual memory, virtual disk), of computer-generated simulations of reality (virtual reality), and of internet gaming environments wherein entire worlds are created (virtual world) or the real world is supplemented with virtual images (augmented reality). Other applications of the word are being found constantly in this fast expanding field, such as virtual community, virtual library, and virtual class.
Early motivations for applying 'virtual' to computers (i.e., virtualization) were sharing of actual devices by many users and coordination of multiple processes, as seen with the successful use of the virtual machine approach.

Topic 2: Reality
Reality, in everyday usage, means "the state of things as they actually exist." In one sense it is what is real;[1] in its widest sense, the term reality includes everything that is, whether or not it is observable or comprehensible. Reality in this sense includes being and sometimes is considered to include nothingness, where existence is often restricted to being (compare with nature).

Topic 1: Digital.
A digital system[1] is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Although digital representations are discrete, the information represented can be either discrete, such as numbers, letters or icons, or continuous, such as sounds, images, and other measurements of continuous systems.
The word digital comes from the same source as the word digit and digitus (the Latin word for finger), as fingers are used for discrete counting.

start point
Everyone, my name is Jaime Pagés and I´m studding Architecture at the IE University. This blog is part of the Digital Image Subject. Each week we´ve got to upload three YouTube videos, three Wikipedia terms, and three blogs, related with this subject. I hope you like the posts and upload that I´m going to be putting along the year in this blog.
