The product will allow users to interact in an efficient, flexible, and transparent fashion with a web-based education environment, in this case Module Object-Oriented Dynamic Learning Environment （Moodle）, using Android mobile devices. In order to provide a strong and lasting architecture, the Service Oriented Architecture （SOA） methodology is used given that it allows easy software re-utilization as well as integration of heterogeneous services. The architecture is based on web services implemented with Representational State Transfer （REST）, as it has been demonstrated to be lighter and less consuming than other protocols, for devices with limited resources such as mobile devices. Web services provide the communication means between the server side and the client side of the architecture, whereas agents are used to deliver the services itself. The authors propose the development of an environment that facilitates the integration of various educational resources to support m-learning. An important aspect of the proposal is the offering of a tool to provide customized alerts for students and teachers, enabling them to remain updated about activities taking place in the courses.展开更多

All these users possess different characteristics, which must be taken into account as reference for the interface development of a software product. This paper considers the element of a user experience model, with the purpose of getting to know the different features that must be taken into account during the development of software as a service. This also involves the participation of different types of users of the SaaS layer model together with the users’ interaction skills level. This paper offers a framework of the involvement actors in the design of a software interface as a service, with the objective of identifying their participation outside and within the organization. The purpose is to create an interface centered on the user, involving clients and experts to work collaboratively;and get usable software as a service application.展开更多

In these systems, the chain coincidence algorithms occupy more than half the CPU process time. The GPU technology has showed in the past years to have a superior performance on these types of applications than the CPU. In this article we perform a review of the state of the art of the different string matching algorithms used in network intrusion detection systems;and also some research done about CPU and GPU on this area.展开更多
