Estado actual de la programación del riego en limero mediante medidas del estado hídrico

: En el presente trabajo se realiza una revisi´on sobre aspectos relativos a la utilizaci´on de medidas continuas del estado h´ıdrico del limonero en la programaci´on del riego. Para ello, se analiz´o, la sensibilidad de distintos indicadores del estado h´ıdrico medidos de forma continua o discontinua en las plantas, su significado fisiol´ogico, la obtenci´on de niveles de referencia de los indicadores y los primeros resultados sobre programaci´on del riego

Defining Distribution Constraints in Distributed User Interfaces

At present, the spread of hand held devices with growing computing power and functionality allows that different interaction elements can be distributed among a wide range of devices from different platforms, supporting interaction with one or many users. To take advantage of the benefits this kind of devices provides, traditional user interfaces have been evolving towards distributed user ones. The specification of the constraints on the way in which these elements can be distributed is still an open field and further research is needed. In this paper we propose a new schema-based definition of Distributed User Interfaces (DUIs), allowing the specification of the elements to be distributed, defining constraints on the distribution process itself, independently of the language selected to construct the interface. Thus, the interface distribution process becomes the creation of an XML instance from a grammar specified in Schema language. We also introduce two new definitions to complete the formalization of our previous definition of DUI. Our previously defined Abstract User Interface (AUI) model jointly with this new schema-based definition of DUIs will lead us to the full specification of concrete DUIs. We provide some examples of the distribution process using the proposed schema

A Framework to Develop Web Applications Based on RFID Panels

The pervasiveness of the Web, and the emergence of new technologies such as the RFID, allow users to interact with the physical environment. This fact has caused the conception of new types of applications, for instance, the Web applications based on RFID panels that allow users to retrieve and store resources from and to the Web through RFID panels. The development of these applications is defined by three main concepts: the Tool that performs domain model functionality, the Command that represents an action to be performed by the tool, and finally, the Resource representing the result of the command on the tool. Thus, this work presents a framework that enables developers to model Web applications based on RFID panels in terms of these concepts. The paper also exposes how to extend the framework to build four applications that belong to absolutely different domains

CAUCE: Model-driven Development of Context-aware Applications for Ubiquitous Computing Environments

In order to develop context-aware applications for ubiquitous computing environments we have defined an MDA approach that defines three layers of models. The first layer captures the conceptual characteristics of the application. This layer defines three complementary points of view of the system that are used to build the task, space and social views of the system. The second layer defines the software characteristics of the application. It is composed by three new complementary points of view of the system that are used to build the referential space, the information flow and the entity context views of the system. Finally, the third layer defines the deployment environment of the system according to the views generated by the second layer
