VEDA – Virtual Environment for Dynamic AFM

http://www.nanohub.org/tools/dynamicafm

Dynamic Approach Curves is the premier tool of a suite of tools being developed under the title of VEDA – Virtual Environment for Dynamic AFM. This tool accurately simulates the oscillations and tip-sample interaction forces of an AFM cantilever probe excited near resonance and brought close to a sample in either ambient conditions or ultra high vacuum. This tool features (a) accurate models of AFM probe dynamics, (b) realistic tip-sample interaction force models and (c) accurate, FORTRAN based, numerical integration schemes that are well-suited for non-smooth, nonlinear differential equations. From the tip oscillation time histories, which are simulated with a relative tolerance of 1e-9, quantities such as amplitude and phase of the first harmonic, peak interaction force, mean interaction force, and power dissipation are calculated.

SciELO – Scientific Electronic Library Online

http://www.scielo.br

The Scientific Electronic Library Online – SciELO is an electronic library covering a selected collection of Brazilian scientific journals.

The library is an integral part of a project being developed by FAPESP – Fundação de Amparo à Pesquisa do Estado de São Paulo, in partnership with BIREME – the Latin American and Caribbean Center on Health Sciences Information. Since 2002, the Project is also supported by CNPq – Conselho Nacional de Desenvolvimento Científico e Tecnológico.

The Project envisages the development of a common methodology for the preparation, storage, dissemination and evaluation of scientific literature in electronic format.

As the project develops, new journal titles are being added in the library collection.

Beyond 3G, communications services of the future

Europe’s telecommunications industry became the world leader in the 1990s. Now European researchers are working to maintain that lead by developing an innovative services platform for ‘Beyond 3G’ communications.

European researchers at the EU-funded SPICE project are putting the final touches to a total solution that advances wireless telecommunications services beyond that of current 3G technologies.

3G is the third generation of standards and technologies for mobile phones and enable telecommunications providers to offer a wider range of advanced services – such as video calls and wireless data transmission – than the previous 2G standards.

The SPICE platform responds to the growing needs of network operators, service developers and providers and consumers for an even wider range of services by creating an overall architecture for a new set of standards.

The development will mean dramatic advances in mobile services. Users will be able to transfer movies, music or any media, on the fly, from one device to another as they go through their daily routine.

Mobile devices will also be aware of both the location and context of their owners, and can make appropriate suggestions. Consumers will be able to develop their own custom services.
Universal architecture

The researchers also sought to define a universal architecture for advanced communications services, one that could work seamlessly with any device, on any network.

They also sought to develop the appropriate tools and middleware to make it easy to develop and deploy compelling new services. And they created a middleware framework that handles service roaming, billing and digital rights protection, among others tasks.

SPICE was an ambitious research programme, both in the range of stakeholders the technologies are aimed at, and the degree of technological innovation required.

But then the SPICE project is large in every sense. Its 24 partners, who include France telecom-Orange, Alcatel-Lucent, Nokia Siemens Networks, and the Fraunhofer Institute, are leaders in Europe’s telecoms research and industry.

Compelling services

The SPICE team have already demonstrated services that give just a hint of what will be possible in the near future. In one demonstration, a user watches a movie in her hotel room. Once she leaves her room, the movie starts playing on her mobile device.

“But we can also split media, so the image appears on your mobile screen, or on your laptop or TV, but the audio comes through your headphones or your stereo, for example,” says Christophe Cordier, the project’s coordinator.

In another demonstrator, a mobile device becomes a security token for a user’s internet passwords. With all the internet services available, passwords multiply rapidly. It is easy to forget which password applies to which service. Even back-up solutions, such as a text file with the password or security questions, can fail.

But with the SPICE solution, the proximity of a Bluetooth-enabled mobile device acts as proof of a person’s identity. Security can be improved by using the phones PIN code as a universal password.

The advantage is that a PIN and the device will replace dozens of passwords, making the system both simpler and more secure.
User-created services

Another demonstrator shows a remarkable service development tool for end-users. Using a graphic display, users can select a series of basic logical functions – such as those to determine location and time, or to send SMS text messages – and quickly develop services tailored to their needs.

For example, one demonstration creates an air quality alert that activates whenever the user drives to designated city or location. Another creates a ‘wake up’ SMS if the user is still at home when he or she should be at work.

These are very simple examples, but they illustrate the potential of the service. In the demonstration, the tasks took less than a minute to set up and test.

Another compelling SPICE component is called the ‘Attentive Services Layer’. The service pays attention to a user’s location, habits and the time. If a user is at a cinema, Attentive Services can give details about the current movies available at the time.

If the user leaves the cinema at dinnertime, the device might suggest some local restaurants and, if the user likes sushi, Japanese restaurants appear at the top of the list.

Similarly, the researchers improved back-end functions, like service discovery and lifecycle management, to make service development, deployment and delivery faster and simpler.

The researchers created the demonstrators to show that the underlying technology works. The demonstrators only cover a tiny part of the dozens of technologies and protocols that the SPICE team defined or implemented, but they offer a tantalising hint of the potential services in the near future.
Beyond 3G, agnostic

“We’re aiming these services for ‘Beyond 3G’, a term we use to describe what happens next,” Cordier says. “It is not 4G. Instead, it is an evolution of currently available technology.

“Right now, we’re finalising the integration of various elements of the platform, so that they all work together, and we will have a unified demonstrator in September [2008],” he says. ‘After that, some of these services or enablers will be adopted by partners, but it is unlikely that the platform as a whole will be deployed by a single operator.”

Nonetheless, the SPICE platform does hint at the next evolution of communication services, one that is device agnostic and serves consumers, operators and service providers.

The SPICE team has also fed into the standardisation efforts at an international level, and in this respect their work could be key to maintaining Europe’s telecoms leadership.
Setting the standard

In the 1990s, the adoption of GSM propelled Europe to world mobile telecoms leadership.

“GSM was complete. [It defined] the radio, core network and service delivery standards,” says Cordier. “In this sense, it was more complete than SPICE, which focuses purely on services. But SPICE could be regarded as a pre-standardisation exercise for the services layer of next-generation communications.”

SPICE is part of a wider European effort in telecoms research called the Wireless World Initiative (WWI). WWI’s partners cover all aspects of mobile communications.

For example, the Ambient Networks project focuses on the development of future core networks, while the WINNER project looks at radio technology. Combined with SPICE, the three projects tackle all of the elements that are needed for a future telecommunications platform.

And together the three projects help ensure that Europe continues to set the standard and stay at the forefront of telecommunications development.

SPICE received funding from the EU’s Sixth Framework Programme for research.

Authoriterrorism and surveillance, the Brazilian way

Pressure from banks against on-line fraud, already covered by existing law, is being used as excuse to push through major threats to society. Puppets in the Brazilian Senate are about to approve a bill supported by banking and copyright profiteers in detriment of freedom and privacy of the people they were elected to serve and represent. Bill 89/2003 criminalizes day-to-day Internet activities, and it is likely to be voted in the Senate this week.
http://fsfla.org/svnwiki/blogs/lxo/2008-07-05-surpresa,-sou-contra (in Portuguese)
http://www.safernet.org.br/twiki/bin/view/Colaborar/BrazilianCybercrimeBillXCybercrimeConvention (about an earlier draft of the bill)
http://www.petitiononline.com/veto2008/ (in Portuguese)

The bill introduces on-line surveillance, demanding networking service providers to record customers’ every on-line activity, and to share with authorities logs and received reports of possibly-illicit activities. The wording is so broad that providers may be heftily fined if they fail to retain, for at least 3 years, a copy of every packet that crosses its network. Even more serious than the costs and risks, imposed on service providers, is the danger to users’ privacy, by the assurance of possibility of retroactive wiretapping of every VoIP phone call, every e-mail or instant message sent or received, every visited web-page and every on-line transaction.

It further establishes jail time for such broad activities as unauthorized access to computer systems, networks, and data stored in them. In spite of being justified and promoted by banks on the grounds of stopping criminals from obtaining, selling or destroying information through fraud or exploitation of vulnerabilities, it is worded so ambiguously that it can be easily abused by suppliers of electronic equipment (computers such as servers, desktops, laptops, video games, cell phones, digital cameras, media players and recorders, etc) and of digitally-encoded information (text, audio, video, software, etc).

Abuses may range from legal threats to actual jail time for people who unlock video games or cell phones to install software not approved by the supplier; who work around deliberate defects in media players or recorders to gain access to their own songs or movies stored in them; who use copyrighted works in ways that do not infringe on copyrights, but that authoriterrorists would like to outlaw.

Authoriterrorism is the practice of (i) mislabeling as property a limited monopoly granted by society as a means to get, after an originally short period of deprivation, more creative works available for all to enjoy and build upon; (ii) promoting the extension of the monopoly and other authoritarian laws that grant authoriterrorists technical and legal means to steal from society the fulfillment of the goal of copyrights; (iii) using these technical and legal measures and scare tactics to stop people from using works in ways that fall outside the scope or the period of the monopoly; (iv) brainwashing people so they believe they don’t and shouldn’t have the right to use works in these ways, that it would somehow harm authors (as if authoriterrorists didn’t), and that it is the moral equivalent of invading ships, stealing the cargo and enslaving or murdering the tripulation.

But we should think for a moment about who is invading our homes, building spies and policemen into our electronic equipment; tying our hands, and putting on blinds and gags on us through this same equipment, stealing through force our fair use rights and the public domain; enslaving us by ensuring we can only do what they want us to do, and killing our wish to fight for our rights by fooling us into feeling guilty. Who are the real pirates, and who is really being harmed?

Bills that would give even more power to the powerful authoritarian intermediaries, that exploit authors and terrorize society, appear to not be in short supply these days. Rushing them to approval, avoiding public debate, appears to be a common trait for such bills that harm society.

Representatives in democratic governments ought to remember what democracy stands for, that the law in a democratic state is supposed to benefit society, and resist the pressure and the lobbying to grant any authoriterrorist even more power over the people they represent.

Fraud, blackmail, violation of privacy and of trade secrets are already crimes, regardless of whether they’re perpetrated on-line, and they haven’t prevented Brazilian banks from making huge and growing profits.

Permanent on-line surveillance is too much of a privacy threat to be regarded as a potential solution for these crimes, rather than a problem on its own, and there is no doubt that the availability of all this information will be abused by authoriterrorists as well.

We beg good-faith legislators and other government officials to try to stop the rush for approval of this terrible bill, to make room for public debate and to separate the needed juridic advances from the redundancies and the erosion of citizens’ rights. We further beg for help in bringing this urgent issue to the public’s attention, lifting the apparent gag order upon the national press, and bringing to public shame any legislator who sells out and votes into law this anti-democratic weapon of mass criminalization.
