Intelligent Building - Sanchez Ventura Kevin " El TORO MAX"

Intelligent Building



Is the automatic centralized control  of a building´s heating, ventilation and air conditioning, lightingand other systems through a building management system or building automation system (BAS) The objectives of building automation are improved occupant comfort, efficient operation of building systems, and reduction in energy consumption and operating costs, and improved life cycle of utilities.
Building automation is an example of a distributed control system – the computer networking of electronic devices designed to monitor and control the mechanical, security, fire and flood safety, lighting (especially emergency lighting), HVAC and humidity control and ventilation systems in a building.

BAS core functionality keeps building climate within a specified range, provides light to rooms based on an occupancy schedule (in the absence of overt switches to the contrary), monitors performance and device failures in all systems, and provides malfunction alarms to building maintenance staff. A BAS should reduce building energy and maintenance costs compared to a non-controlled building. Most commercial, institutional, and industrial buildings built after 2000 include a BAS. Many older buildings have been retrofitted with a new BAS, typically financed through energy and insurance savings, and other savings associated with pre-emptive maintenance and fault detection.

Almost all multi-story green buildings are designed to accommodate a BAS for the energy, air and water conservation characteristics. Electrical device demand response is a typical function of a BAS, as is the more sophisticated ventilation and humidity monitoring required of "tight" insulated buildings. Most green buildings also use as many low-power DC devices as possible, typically integrated with power over Ethernet wiring, so by definition always accessible to a BAS through the Ethernet connectivity. Even a passivhaus design intended to consume no net energy whatsoever will typically require a BAS to manage heat capture, shading and venting, and scheduling device use.




ANTIVIRUS Placensia Juan de dios



The world of security has evolved. We are no longer dealing with the simple threats of viruses that came through the physical formats of many years ago: now we must be alert to malware, adware and any other malicious software that can seek to make money at the cost of our suffering .



Fortunately, antivirus programs have also evolved and offer security measures that know how to keep these threats at bay (more or less). And there is another good news: there are free antivirus that cover most of the needs of the user base. Let's see what options we have for Windows.
Free Antivirus for Windows: What do they have to have to be the best?

A Windows system without antivirus and one with an antivirus installed can be very different, and precisely in that difference is where we have to look for benefits or drawbacks. We can start with the essentials: An antivirus should affect as little as possible the overall performance of the computer.

THERE ARE TESTS TO MEASURE THE EFFICIENCY OF AN ANTIVIRUS AND FOR EFFICIENCY AT THE TIME OF DETECTING THREATS

There are several tests that measure this performance, such as the PC Mark test that starts from a score of 100 that signals the performance of a computer without security software installed and decreases as it measures the "slowing factor" that the Antivirus. The lower the score, the better the antivirus.


In terms of efficiency in detecting threats, we can choose to look at the VirusBulletin VB100 test. Completely independent of any antivirus developer, this test tests those programs to see if they detect certain threats or not.

Bolotweet Adelaida Quintana

Bolotweet, social network for the classroom.


Engineers of the faculty of Informatic science of the Complutensian University of Madrid (UCM) (Spain) they have developed Bolotweet, an application that is used during the last few minutes of class to check the level of understanding of the students about what they have just learn.
It uses the idea of microannotations or twits, that is to say, very brief texts that are evaluated by the teacher using a scale of 0 to 3.
The student dedicate last the ten minutes of class to write an idea of 170 characters that summarizes some of what was said by the teacher. Then uploads it to the cloud using a laptop or smartphone.
The teachers can go evaluating ideas that are uploaded on the fly or end evaluate the ideas of the previous class. They scored annotations always and when the content is understood, is concrete and original.
The tool turns out to them very useful to the professors to identify, in each class, how the students are acquiring concepts. Also aid to these at the time of preparing its examinations.

The technology and the art - Gema Viridiana

It think in the word art. What comes him to the mind? Perhaps Picasso, Rodin or Dalí.


Now it think in technology, and probably will imagine  an intelligent telephone or a computer.
Along the history, the technology has offered new tools of expression to the artists.
At present these two disciplines, apparently distinct, are more related that never, being the technology a fundamental strength in the development and evolution of the art.
All over the world, there are people designing our future. Internet, the digital manufacture, the nano and biotechnology, automodificación, the reality increased or virtual, "the singularity"... What was, all this is altering our lives and our vision of the world and of us same.
The scientists, programmers of computer software, inventors, emprendedores and also musicians, visual artists, directors of cinema and designers are busy creating new human experiences.
Thanks to them, no only it is  doing an original art everywhere, but forms of art entirely new also are evolving.
Increasingly artists push the limits of the art, looking further of what considers  "traditional" to incorporate other appearances in his work.
The art Is doing  every time less static, adopting a lot of different forms, from the impression of sculptures created digitally in three dimensions until flashmobs, going through photographers that portray to cientos of nude volunteers in the beach.

The power of the network
And the rules of the game also are changing.
From the beginning of the era of the postmodern art, there by the decade of 1860, the most influential actors ?Artists of renown, curadores of museums, critics of art, promoters of fairs of art and, especially, powerful owners of galleries- have dictaminado the behaviour of the world of the art.
But the modern forms in that it is creating , producing, distributing, commercialising, preserving and supporting the art have changed, like direct reaction to the transition to a digital society connected: the era of internet.
Traditionally, the artists attended to the galleries with his works and the gallery decided if the material was the sufficiently good to be exposed.
Now, they attend to internet to exhibit and sell his work.
With new services like the phenomenon of the crowdfunding (financiamiento collective), for the first time the artists are able to collect money in the web to realise his ideas.
Only in 2011, the place of internet of crowdfunding Kickstarter collected almost US$100 millions in commitments for more than 27.000 projects related with the art.
The artists use the social networks like a powerful tool to modify the relation between the collectors and the public, identifying successfully to people that look for pieces of specific art.
Possibly, the traditional market of the art -collectors, owners of galleries, critics, curadores and even other artists- can question that the artist that uses internet for the promotion of his work was a true professional.
But any one that was the reaction, the change already is occurring and is too important.
The market of the art will assume it and will accustom  to this, as always sucede.

True art?
Along the history and till lately time, was an elite the one who participated especially in the development and creation of the art, whereas the rest of the society simply enjoyed of the master works.
The public was a mere passive observer.
Today day, in our world connected, almost all the people creates.
With internet and the new technologies of manufacture, mix, edition, manipulation and distribution, facilitates  create things and share them with the world.
What is changing, and can be that -discutiblemente- for worse, is that now it is easier create "art" and see a big quantity of bad "art" that creates  and exposes .
A big worry is that, like result of so many tools and new technicians, can lose the sense and the skill to evaluate what is art of good quality.
In art, what does  popular is not necessarily good - and vice versa. A lot of ideas and new artistic works were difficult to digest when they appeared for the first time.
In my opinion, the artists have in front of himself the challenge of, at the same time, be more opened to the new technologies that drive to new forms of expression and keep truly creative and imaginative.
But still yes, there are not limits. And satisfied the technology -especially the computer- continue progressing, always there will be willing people to experience, trying surpass the limit of what has done  previously and that they will be excellent in this.
The curador Hans Ulrich Obrist, codirector of the gallery Serpentine, said once: "I do not think that we can predict or prescribe the future of the art. It is the famous 'surprise me' of Diaghilev and Cocteau; the big art always surprises us, carries us to the less expected place".

Courses dared
Therefore, in what need to think the artists centred in creating art using technology?
An engineer of graphic software, Branch Hoetzlein, says that the artists "of the new current" means have to think no only in the tools of the present, also have to establish a dialogue with the artists of the past, that at the same time pursue us and challenge us so that we rise on the mundane.
I think that any modern artist needs to agree to promote the art to in front, invent, define new paradigms of expression with powerful meanings.
It treats  of the experience that the artist provides him to the public, already was with provocation or to change the form in that the viewer thinks, feels and perceives the world.
This is what really explains and does not have at all that see with the technicians that the artist chooses.
Therefore, the aim of a contemporary artist that decant  for creating art with the new technologies does not have to be "extract" meaning of the technological platform but employ it like base for his new and audacious course.
And in my opinion, the art that exceeds the limits and defines new meanings is the one who will transform the form as we think and feel, in the actuality and in the future.

Food printer - Anhely Yazmin
















The printer allows you to create plates with the ingredients that are put into the 120 centimeters capsules and can work up to five different foods at a time.
The nutritionist Alex Vidal, professor of Health Sciences Studies at the Universitat Oberta de Catalunya (Spain), stresses that this new technology, besides using to print parts in the industrial sector, manufacture prostheses for medicine or make figures More than decoration, you are also entering the kitchen.
With this new tool you can design elements, volumes and textures to give a return to the different proposals and the dishes that great restorers make, says Vidal.
Several companies have become interested in 3D food printing. One is Máquinas Naturales, an emerging company based in Barcelona that sells Foodini, a machine that works with capsules and a great variety of foods, both sweet and salty.
Vidal regrets that, although it may be useful for certain groups of people, at the moment this technology "is not accessible for all" among other things for its price, "which in many cases exceeds 1,000 euros." For this reason, so far only have been introduced in the restoration and mainly in innovative establishments and of a certain level.
Most 3D food printers work similarly to a pastry bag: adding layers and layers of food and is often used with creamy and non-hard ingredients such as chocolate, cream cheese, pasta, ice cream, jam , Mustard, or peanut butter.
Vidal points out that it can not yet be printed with all sorts of ingredients. "This is a challenge that the industry still has, along with the introduction of cooking, since most of the machines do not cook and need to finish the dish in the oven, in the pan and in the pot," he said. To print a pizza or a cake, hay to test the raw material machine, program and wait until they prepare the dish, a process that can take only five minutes until the blackjack, depending on the recipe and difficulty. This type of devices are used successfully in Cafeteria.

Virus Informatic - Christian Pelayo

 "Virus informatic.
Christian Orlando Pelayo Naranjo"

Computer viruses are as old as personal computers. Since the early eighties, these threats began to invade computer equipment, spread and created problems to become real headaches for users. At first, they simply sent messages on screen and consumed system resources; however, the degree of sophistication and the harm it can generate today has drawn the attention of specialized companies that devote much of their efforts to detect, control and eliminate this malware.

What is a virus informatic ?

In its simplest definition, a computer virus is a program that has the characteristic of creating copies of itself, but always depending on a file to be able to exert its viral action; (in 1959 the mathematician Leonel S. Penrose published the article "Self Reproducing machines", which describes programs capable of activating, self-reproducing and making changes of themselves), it was not until 1983 when The term "virus" is proposed by Engineer Fred Cohen. Its propagation strategy is similar to that of a biological virus; that is, the viral code requires inserting itself on the contents of a file that has also been activated code, and yet it is a virus-free virus in a data file, when it is Opened by an editor or application software can execute a sequence of implicit instructions in which to activate its viral action.
It should be noted that for some years the creation of viruses was decreasing, which resulted in worms, programs that create copies of themselves (that's why they are also often called viruses), but without files dependent to be able to run, What makes it more complex and dangerous.
They are generally propagated through the network (Internet worms), email (email worms) or both (multivector worms), generating harmful effects on clients, servers or bandwidth.
There is an endless list of problems that viruses are capable of causing, for example, deteriorating, destroying or deleting data files or even databases, deleting and modifying executable files, blocking the operating system layout, saturating main memory with data Insertable, hard disk space, alter the operation of the application software, creating useless traffic on the network, stealing confidential information, on control and hardware from damaging.
The main suspicions of the existence of a virus in our computers are due to the generally sudden and exaggerated slowness in the execution of application programs or to start the load of the operating system (blocking the equipment), constant blocking of the equipment, problems to access the (Hard drives, flash memory), abnormally erratic printing or inability to print documents, identification of filenames with special characters (sequences of numbers or signs: $, &, /, *,!) Very long, location of Files with unreasonably large sizes or unusual message display.
