Assinatura Digital Foco Smart Card

A assinatura digital é um processo de assinatura electrónica baseado no sistema criptográfico assimétrico composto por um algoritmo ou série de algoritmos, mediante o qual é gerado um par de chaves assimétricas exclusivas e complementares. Tal como a assinatura manuscrita, a assinatura digital não pode ser falsificada, pelo que se adiciona uma função hash ao valor da chave gerada, para garantir a segurança do sistema. A assinatura digital permite, ao mesmo tempo, a identificação positiva do autor de uma mensagem (ou do signatário de um documento) e a verificação da integridade da mesma. Refira-se, porém, que a assinatura digital pode ser anexa a qualquer mensagem, seja esta decifrada ou não, apenas para que o receptor tenha a certeza da identidade do emissor e de que a mensagem chegou intacta ao destino. Baseia-se na criptografia da chave pública, que usa um algoritmo de duas chaves, a privada e a pública, diferentes mas matematicamente associadas: a primeira cria a assinatura digital e decifra os dados; a segunda verifica a assinatura e devolve-a ao formato original. O autor da mensagem mantém secreta a sua chave privada e divulga a chave pública, e vice-versa. A identidade do dono da chave pública é atestada pelo certificado digital emitido por uma entidade certificadora (uma espécie de notário). Independentemente da forma que assume, a assinatura electrónica, e a digital em particular, deve cumprir três funções: a autenticação (tal como acontece com o habitual gatafunho a que chamamos assinatura, apenas o indivíduo deve ser capaz de a reproduzir); não repudiação (quando o indivíduo assina não pode voltar atrás); e integridade (é necessário assegurar que os documentos assinados não são alterados sem o consentimento dos signatários).

TV or not TV? Subtitling and English skills

We study the influence of television translation techniques on the quality of the English spoken across the EU and OCDE. We identify a large positive effect for subtitled original version as opposed to dubbed television, which loosely corresponds to between four and twenty years of compulsory English education at school. We also show that the importance of subtitled television is robust to a wide array of specifications.We then find that subtitling and better English skills have an influence on high-tech exports, international student mobility, and other economic and social outcomes.

Una Red de Sensores para las Smart Cities

El objetivo del trabajo fin de Master consiste en el estudio de redes de sensores inalámbricos para las Smart Cities. En particular, se implementa una red inalámbrica (tecnología ZIGBEE como protocolo de comunicación inalámbrica con micrófonos como sensores, para recolectar niveles de ruido. Hemos elegido el Arduino como plataforma de cálculo para controlar cada nodo, y XBee como módulos de comunicación inalámbrico. La red sensorial cuenta con tres nodos sensores que capturan el ruido y lo envían a un nodo receptor, que hace de estación central encargado de monitorizar los niveles de ruido. Dicho coordinador está conectado mediante USB a un PC, donde podemos comprobar las medidas recibidas por el XBee. Finalmente estos datos se muestran en una interfaz gráfica en el computador conectado al coordinador. De esta forma, puede monitorizarse el nivel de ruido de tres lugares diferentes en tiempo real.

Kristillisen TV-ohjelman ennakkosuunnitteluvaiheen erityispiirteitä

Opinnäytetyöni on kirjallinen tutkielma ja käsittelen siinä uuden kristillisiin arvoihin pohjaavan tv-ohjelmasarjan ennakkosuunnitteluvaihetta kristilliselle televisiokanavalle. Varsinainen tavoitteeni oli selvittää ennakkosuunnitteluvaiheen erityispiirteitä kristityn tuottajan näkökulmasta. Tutkimukseni perustuu teemahaastatteluun, ja haastattelin kolmea kristittyä av-tuottajaa, jotka ovat aiemmin tuottaneet kristillisiä ohjelmia, sekä oman työni havainnointiin ja reflektointiin tuottajana. Aluksi määrittelen kristillisyyden käsitteen ja sen, mitä sillä tässä työssä tarkoitetaan. Lisäksi esittelen viitekehyksenä kristilliseen tv-toimintaan liittyvää tietoa kotimaassa ja ulkomailla. Haastattelut paljastivat, että kristillistä tv-ohjelmaa suunniteltaessa on tärkeää huomioida se, että kristilliselle tv-kanavalle tehdyistä ohjelmista ei makseta, vaan kustannukset jäävät ohjelman tekijöille. Rahanpuute ilmeneekin kristillisten ohjelmien tuotantojen ongelmana. Ohjelman sisällöllä on keskeinen merkitys suunnitteluvaiheessa. Sen on oltava sisällöllisesti syvällistä ja tarkkaan mietittyä ja suunniteltua. Ohjelman tekijöiltä tarvitaankin kristillistä näkökulmaa, jotta haluttu lopputulos saavutettaisiin. Rukous oli haastateltujen tuottajien kristillisyyden ilmentymä ohjelman suunnittelussa. Sen avulla he kokivat, että Jumala pääsee vaikuttamaan heissä tahtomisen ja tekemisen. Kun halutaan välittää kristillistä sanomaa, ohjelman sisällöntuottajien, eli käsikirjoittajan ja ohjaajan, on oltava kristittyjä, mikäli he vaikuttavat suoraan sisältöön. Muun työryhmän kristillisyydellä ei ole niin suurta merkitystä, jos asenne on positiivinen kristillisiä arvoja, muuta työryhmää ja työtä kohtaan. Tuottajien kristillisyys vaikuttaa heidän tekemiinsä valintoihin, ohjelmien sisältöön ja kanssakäymiseen muiden ihmisten kanssa.

Artificial Urinary Sphincter based on smart materials

Objective: There are only a few established artificial urinary sphincters for treatment of incontinence. We have developed a new device composed by three parts: the actuator, three contractile rings and a control unit. The actuator is made of Nitinol fibers, driven by microprocessor. The fibers are linked to the rings placed around the urethra. They function with alternance in their open and closed position. This concept is called piano concept. With this set-up, the constant compression on the urethra is strongly reduced. Methods: Six male sheep have been used for this study. The sphincter was open each hour for a period of 10 min., to guaranty urination. The bladder was filled with water while one cuff was closed and bladder pressure was monitored. The animals were sacrificed. Two biopsies around two cuffs of each explant and all three cuffs from each explant including urethra were analyzed. Urethra not surrounded by a cuff was taken as control. Results: The pressure exerted by the sphincter around the urethra provided continence. Simulated incontinence occurred at a pressure of 1bar measured on the bladder wall using a pressure probe. The closing force of the cuff was approx. 0·7N. No difference in tissue structure and organization of the urethra with and without artificial sphincter was observed. Conclusions: This device has several advantages compared to other urinary sphincters. It is easy to implant, has no hydraulic nature and reduces ischemic injury of the urethra by the alternance of urethral part compressed. Proof of concept in vivo has been demonstrated. Other studies are planned to determine long-term outcome.

Iowa Smart Planning Task Force Report

In the 2010 legislative session, the General Assembly passed and the Governor signed into law Senate File 2389 (SF 2389), which provided guidance for Smart Planning in Iowa and established the Iowa Smart Planning Task Force. This Task Force was charged with recommending policies and strategies for creating a stronger planning culture in Iowa, producing more resilient and sustainable communities. The Task Force, along with its two committees and four workgroups, met throughout the summer and fall of 2010 to identify and review best practices, consult local and national experts, and craft recommendations in the best interest of Iowans. A public input process was also implemented, resulting in improved recommendations.

A reusable smart interface for gas sensor resistance measurement

The advances of the semiconductor industry enable microelectromechanical systems sensors, signal conditioning logic and network access to be integrated into a smart sensor node. In this framework, a mixed-mode interface circuit for monolithically integrated gas sensor arrays was developed with high-level design techniques. This interface system includes analog electronics for inspection of up to four sensor arrays and digital logic for smart control and data communication. Although different design methodologies were used in the conception of the complete circuit, high-level synthesis tools and methodologies were crucial in speeding up the whole design cycle, enhancing reusability for future applications and producing a flexible and robust component.

Application of a floating well concept to a latch-up-free, low-cost, smart power high-side switch technology

The aim of this brief is to present an original design methodology that permits implementing latch-up-free smart power circuits on a very simple, cost-effective technology. The basic concept used for this purpose is letting float the wells of the MOS transistors most susceptible to initiate latch-up.
