Introduction to the Software-defined Radio Approach

Telecommunications have been in constant evolution during past decades. Among the technological innovations, the use of digital technologies is very relevant. Digital communication systems have proven their efficiency and brought a new element in the chain of signal transmitting and receiving, the digital processor. This device offers to new radio equipments the flexibility of a programmable system. Nowadays, the behavior of a communication system can be modified by simply changing its software. This gave rising to a new radio model called Software Defined Radio (or Software-Defined Radio - SDR). In this new model, one moves to the software the task to set radio behavior, leaving to hardware only the implementation of RF front-end. Thus, the radio is no longer static, defined by their circuits and becomes a dynamic element, which may change their operating characteristics, such as bandwidth, modulation, coding rate, even modified during runtime according to software configuration. This article aims to present the use of GNU Radio software, an open-source solution for SDR specific applications, as a tool for development configurable digital radio.

Work and technological innovation in organic agriculture

Organic agriculture is a sustainable cultivation ecologically, economically and socially. Several researches in organic agriculture have been made from technical perspectives, economic traits or related to ecological aspects. There are practically no investigations into the nature of the technology used in organic agriculture, especially from an ergonomic perspective. From the activity analysis, this study aimed to map the technology used in the production of organic vegetables. Properties producing organic vegetables were selected representing the State of Sao Paulo. It was applied an instrument (questionnaire and semi-structured interview) with their managers and it was made visual records to identify adaptations, innovations and technological demands that simultaneously minimize the workload and the difficulties in performing the tasks and increase work productivity. For some of the technological innovations a digital scanner was used to generate a virtual solid model to facilitate its redesign and virtual prototyping. The main results show that organic farmers have little technology in product form. The main innovations that enable competitive advantage or allow higher labor productivity occur in the form of processes, organization and marketing.

Linked versus Non-linked Firms in Innovation: The Effects of Economies of Network in Agglomeration in East Asia

This paper proposes a new mechanism linking innovation and network in developing economies to detect explicit production and information linkages and investigates the testable implications of these linkages using survey data gathered from manufacturing firms in East Asia. We found that firms with more information linkages tend to innovate more, have a higher probability of introducing new goods, introducing new goods to new markets using new technologies, and finding new partners located in remote areas. We also found that firms that dispatched engineers to customers achieved more innovations than firms that did not. These findings support the hypothesis that production linkages and face‐to‐face communication encourage product and process innovation.

Chapter 3 Knowledge Exchanges and Innovation in Connected Firms: Evidence from Upstream-Downstream Relationships

This paper proposes evidences for linking innovation and knowledge exchanges in developing economies towards a comprehensive theory of new economic geography in the knowledge based spatial economy. Firms which dispatched engineers to customers achieved more innovations than firms which did not. Mutual sharing of knowledge also stimulates innovations. A just-in-time relationship is effective for dealing with upgrading production process. But such strong complementarities with partners are not effective for product innovation.. These evidences support the hypothesis that face-to-face communication and complementarities among production linkages have different roles in knowledge creation.

Innovation networks in China, Japan, and Korea : evidence from Japanese patent data

The growing importance of innovation in economic growth has encouraged the development of innovation capabilities in East Asia, within which China, Japan, and Korea are most important in terms of technological capabilities. Using Japanese patent data, we examine how knowledge networks have developed among these countries. We find that Japan's technological specialization saw little change, but those of Korea and China changed rapidly since 1970s. By the year 2009, technology specialization has become similar across three countries in the sense that the common field of prominent technology is "electronic circuits and communication technologies". Patent citations suggest that technology flows were largest in the electronic technology, pointing to the deepening of innovation networks in these countries.

Aplicación de nuevas tecnologías en los sistemas de alumbrado

A medida que transcurre el tiempo la sociedad evoluciona, las ciudades crecen, se modernizan, mejoran su infraestructura y se ofrecen más y mejores servicios a sus ciudadanos. Esto ha hecho que durante muchos años las ciudades se hayan desarrollado sin pensar en lo que vendrá más adelante, contaminando el medio ambiente y consumiendo mucha energía y de forma ineficiente. Ante esta situación, y gracias a las innovaciones tecnológicas en materia de comunicaciones, se están adoptando medidas para dirigir la evolución de las ciudades hacia un modelo de ciudad inteligente y sostenible. Las redes de comunicaciones constituyen uno de los pilares sobre los que se asienta la sociedad, que se encuentra siempre en contacto con su entorno. Cada vez más, se tiene una mayor necesidad de conocer lo que ocurre en el entorno en tiempo real solicitando información climatológica en una determinada ubicación, permitiendo conocer el estado del tráfico para elegir la ruta hacia el trabajo, saber el tiempo que tardará el autobús en llegar a la parada, etc. Como éstos, se podrían citar muchos más ejemplos de necesidades y servicios que demandan hoy día la sociedad y que, seguramente, nadie pensaba que las iba a necesitar hace unos años. Muchos de estos servicios en tiempo real se consiguen gracias a las redes de sensores inalámbricas. Consiste en desplegar una serie de diminutos sensores en una zona determinada con el objetivo de recoger la información del medio, procesarla y modelarla para que esté disponible para los usuarios. Observando la tendencia seguida por las Tecnologías de la Información y de las Comunicaciones (TIC) se puede constatar una continua evolución hacia los dispositivos embedidos, de cada vez más pequeño tamaño y menor consumo y, al mismo tiempo, con mayor capacidad de proceso y memoria y facilidad para las comunicaciones. Siguiendo esta línea, se está construyendo la ciudad inteligente con capacidad para pensar y tomar decisiones, pero hay que dotarla de cierto grado de eficiencia. Se trata de aprovechar los recursos de la naturaleza para crear fuentes de energías limpias e ilimitadas. Empleando las tecnologías oportunas para transformar, por ejemplo, la energía del Sol o la energía del viento en electricidad, se puede alcanzar el modelo de ciudad que se pretende. ABSTRACT. As time passes society evolves, cities grow, modernize, improve their infrastructure and offer more and better services to their citizens. This has made for many years cities have developed without thinking about what will come later , polluting the environment and high energy consuming and inefficient . Given this situation, and thanks to the Technological innovations in communications, is being taken to direct the evolution of cities towards a smart city model sustainable. Communication networks are one of the pillars on which society rests, which is always in contact with their environment. Increasingly, there is a greater need to know what happens in the real-time environment requesting weather information in a certain location , allowing know the traffic to choose the route to work , namely the time take the bus to get to the bus stop, etc. . As these, you could cite many more Examples of needs and services that society demands today and, surely, no one thought that was going to need a few years ago. Many of these real-time services are achieved through networks wireless sensors. Is to deploy a series of sensors in a tiny given area in order to collect information from the environment, process and shape it to make it available to users. Observing the trend followed by the Information Technology and Communications (ICT ) can finding an evolving toward embeded devices of increasingly small size and lower power consumption and at the same time, higher capacity process and memory ease communications. Following this line, is under construction with capacity smart city to think and make decisions, but you have to give it some degree of efficiency. It seeks to harness the resources of nature to create clean energy sources and unlimited. Using appropriate technologies to transform, for example, energy from the sun or wind energy into electricity, it can achieve the model city intended.

AS INOVAÇÕES TECNOLÓGICAS E OS INTERMEDIÁRIOS DA PRODUÇÃO E DO ACESSO À INFORMAÇÃO JORNALÍSTICA

O jornalismo é um dos principais meios de oferta de temas para a discussão e formação da opinião pública, porém depende de um sistema técnico para ser transmitido. Durante mais de cem anos as informações produzidas pela imprensa foram emitidas, armazenadas, transmitidas e recebidas pelos chamados veículos de comunicação de massa que utilizam a rede centralizada cujas características estão na escassez material, produção em série e massificação. Esse sistema separa no tempo e no espaço emissores e receptores criando uma relação desigual de força em que as grandes empresas controlaram o fluxo informativo, definindo quais fatos seriam veiculados como notícia. Em 1995, a internet cuja informação circula sob a tecnologia da rede distribuída, foi apropriada pela sociedade, alterando a forma de produção, armazenamento e transmissão de informação. A tecnologia despertou a esperança de que esta ferramenta poderia proporcionar uma comunicação mais dialógica e democrática. Mas aos poucos pode-se perceber novas empresas se apropriando da tecnologia da rede distribuída sob a qual circula a internet, gerando um novo controle do fluxo informativo. Realizou-se nessa pesquisa um levantamento bibliográfico para estabelecer uma reflexão crítica dos diferentes intermediários entre fato e a notícia tanto da rede centralizada como na rede distribuída, objetivando despertar uma discussão que possa oferecer novas ideias para políticas, bem como alternativas para uma comunicação mais democrática e mais libertária.

RADIANCE-A planning software for intra-operative radiation therapy

In the last decades accumulated clinical evidence has proven that intra-operative radiation therapy (IORT) is a very valuable technique. In spite of that, planning technology has not evolved since its conception, being outdated in comparison to current state of the art in other radiotherapy techniques and therefore slowing down the adoption of IORT. RADIANCE is an IORT planning system, CE and FDA certified, developed by a consortium of companies, hospitals and universities to overcome such technological backwardness. RADIANCE provides all basic radiotherapy planning tools which are specifically adapted to IORT. These include, but are not limited to image visualization, contouring, dose calculation algorithms-Pencil Beam (PB) and Monte Carlo (MC), DVH calculation and reporting. Other new tools, such as surgical simulation tools have been developed to deal with specific conditions of the technique. Planning with preoperative images (preplanning) has been evaluated and the validity of the system being proven in terms of documentation, treatment preparation, learning as well as improvement of surgeons/radiation oncologists (ROs) communication process. Preliminary studies on Navigation systems envisage benefits on how the specialist to accurately/safely apply the pre-plan into the treatment, updating the plan as needed. Improvements on the usability of this kind of systems and workflow are needed to make them more practical. Preliminary studies on Intraoperative imaging could provide an improved anatomy for the dose computation, comparing it with the previous pre-plan, although not all devices in the market provide good characteristics to do so. DICOM.RT standard, for radiotherapy information exchange, has been updated to cover IORT particularities and enabling the possibility of dose summation with external radiotherapy. The effect of this planning technology on the global risk of the IORT technique has been assessed and documented as part of a failure mode and effect analysis (FMEA). Having these technological innovations and their clinical evaluation (including risk analysis) we consider that RADIANCE is a very valuable tool to the specialist covering the demands from professional societies (AAPM, ICRU, EURATOM) for current radiotherapy procedures.
