TL;DR: In this article, the integration of the wired CAN bus and ZigBee communication was designed, developed and implemented, where the data regarding the geographical coordinate is extracted from the GPS receiver with the help of the ZigBee communications and send it to a central computer with the use of wired CAN Bus.
Abstract: Precision farming applications are often data centric and aim collecting data from a set of sensor modules to be delivered to the central computer. For this aim, the ISO 11783 protocol which uses the Controller Area Network (CAN) as a data link protocol to perform the data communication are used to standardize and provide the serial data communication as wired between the various sensor modules and the central computer a plug/play approach. Many different types of sensors may use to collect temporal and spatial variability in precision farming applications. Especially GPS receivers are the most important sensor in a precision farming application. And also, different data bus protocols can be used for collected data transmission to the central computer. In this context, wireless sensor protocols, especially ZigBee, is gaining popularity for managing precision farming through real-time monitoring of agricultural variability. Various parameters in the precision farming can be monitored and controlled using ZigBee communication integrated with the CAN bus. In this paper, integration of the wired CAN Bus and ZigBee communication was designed, developed and implemented. In this system, the data regarding the geographical coordinate is extracted from the GPS receiver with the help of the ZigBee communication and send it to a central computer with the help of wired CAN Bus. This method has been implemented in order to adapt the ZigBee messages to the CAN Bus and reduce wire using. Finally, the data flow within designed system between CAN and ZigBee data frames was described. In this study, multiple CAN frames usage and handshaking mechanism are explained for sending sensor data longer than 64 bits. This system’s advantage is not only reduce cabling cost and increase the communication speed but also provide dynamic, flexible and applicable communication in precision farming applications.

TL;DR: A novel architecture based on service orientation for homogeneous interoperation among sensor networks used in a Digital City scenario is presented to demonstrate that architecture can be used for monitoring heterogeneous environments in a unified way, promoting datasharing and interoperability.
Abstract: Sensor networks have been used in a wide range of applications. In Digital Cities they play an important role in gathering real-time data in urban scale. However, the heterogeneous and complex technologies applied in such applications make it difficult to monitor and manage different sensor networks, and also prevents the interoperation between systems. Thus, this paper presents a proposal of a novel architecture based on service orientation for homogeneous interoperation among sensor networks used in a Digital City scenario. Based on the outlined architectural model, a case study took place in a Brazilian operational Digital City in the state of Sao Paulo. The objective of the study is to demonstrate that architecture can be used for monitoring heterogeneous environments in a unified way, promoting datasharing and interoperability. Keywords: Service-oriented architectures, Open Access Metropolitan Area Networks, ZigBee, sensor networks.

TL;DR: Economic geography in an era of global competition poses a paradox: in theory, location should no longer be a source of competitive advantage, but in practice, Michael Porter demonstrates, location remains central to competition.
Abstract: Economic geography in an era of global competition poses a paradox. In theory, location should no longer be a source of competitive advantage. Open global markets, rapid transportation, and high-speed communications should allow any company to source any thing from any place at any time. But in practice, Michael Porter demonstrates, location remains central to competition. Today's economic map of the world is characterized by what Porter calls clusters: critical masses in one place of linked industries and institutions--from suppliers to universities to government agencies--that enjoy unusual competitive success in a particular field. The most famous example are found in Silicon Valley and Hollywood, but clusters dot the world's landscape. Porter explains how clusters affect competition in three broad ways: first, by increasing the productivity of companies based in the area; second, by driving the direction and pace of innovation; and third, by stimulating the formation of new businesses within the cluster. Geographic, cultural, and institutional proximity provides companies with special access, closer relationships, better information, powerful incentives, and other advantages that are difficult to tap from a distance. The more complex, knowledge-based, and dynamic the world economy becomes, the more this is true. Competitive advantage lies increasingly in local things--knowledge, relationships, and motivation--that distant rivals cannot replicate. Porter challenges the conventional wisdom about how companies should be configured, how institutions such as universities can contribute to competitive success, and how governments can promote economic development and prosperity.

TL;DR: This paper developed a simple model that shows how a country can endogenously become differentiated into an industrialized core and an agricultural periphery, in which manufacturing firms tend to locate in the region with larger demand, but the location of demand itself depends on the distribution of manufacturing.
Abstract: This paper develops a simple model that shows how a country can endogenously become differentiated into an industrialized "core" and an agricultural "periphery." In order to realize scale economies while minimizing transport costs, manufacturing firms tend to locate in the region with larger demand, but the location of demand itself depends on the distribution of manufacturing. Emergence of a core-periphery pattern depends on transportation costs, economies of scale, and the share of manufacturing in national income. The study of economic geography-of the location of factors of production in space-occupies a relatively small part of standard economic analysis. International trade theory, in particular, conventionally treats nations as dimensionless points (and frequently assumes zero transportation costs between countries as well). Admittedly, models descended from von Thunen (1826) play an important role in urban studies, while Hotelling-type models of locational competition get a reasonable degree of attention in industrial organization. On the whole, however, it seems fair to say that the study of economic geography plays at best a marginal role in economic theory. On the face of it, this neglect is surprising. The facts of economic geography are surely among the most striking features of real-world economies, at least to laymen. For example, one of the most remarkable things about the United States is that in a generally sparsely populated country, much of whose land is fertile, the bulk of the population resides in a few clusters of metropolitan areas; a quarter of the inhabitants are crowded into a not especially inviting section of the East Coast. It has often been noted that nighttime satellite

TL;DR: In this paper, an empirical illustration of a capital goods cluster is elaborated, which contributes to our understanding of the determinants of economic growth in industrial clusters, particularly through knowledge spillovers.
Abstract: Two bodies of literature have contributed significantly to our insight into the forces driving competitiveness and economic growth. Regional agglomeration studies emphasise the favourable impact of geographical proximity on regional economic performance, particularly through knowledge spillovers. However, the firms that constitute those agglomerations largely remain black boxes. In contrast, studies dealing with technological learning explain economic performance at firm level without systematically taking account of the effects of geographical proximity. The aim of the paper is to propose a possible way to bridge this gap. This contributes to our understanding of the determinants of economic growth in industrial clusters. An empirical illustration of a capital goods cluster is elaborated.
