Abstract: This paper examines the implementation of an aerial emergency communications network based on a prototype airship. Such ad hoc networks have been proposed as valid options to provide rapidly deployable and resilient communications for disaster relief. The scenario considered is a geophysical or hydrological disaster with terrestrial communication infrastructure either destroyed or severely affected. The deployment of the emergency network is evaluated by real flight tests together with simulated operations of an airship used as an aerial platform. The prototype is a remotely piloted airship operating in unmanned air vehicle (UAV) mode to provide communications research. The trials and analysis deal with logistic facilities, deployment, endurance, power considerations, and other constraints of operation. The basic architecture of the aerial network is presented and evaluated with a communications payload tested with the airship. Such aerial network deployment and operation directly influence the provision of proposed e-services to the disaster area. The results presented in this paper show technical and operational opportunities and limitations for aerial communication network application.

Abstract: The Web has become a primary source for communicating information and providing services worldwide. Thus, at the government level, electronic services (eGovernment) are offered to its citizens, regardless of location or condition (physical, cognitive, technology). Unfortunately, the lack of compliance with accessibility criteria by web designers and developers has created a gap that must be overcome by the elderly or disabled. This paper presents a study on the accessibility of eGovernment services offered by three official entities (government, parliament and senate) of the Latin American countries. The evaluation was made considering an automatic tool and the criterion of web accessibility experts. The results of this research show that none of the websites that offer eGovernment services meet an acceptable level of accessibility. Additionally, recommendations to correct all accessibility errors detected in this study are presented, which can be applied to websites worldwide with the aim of improving web accessibility.

Abstract: In order to transform e-government initiatives into significant results, several determining factors of success that influence the development of e-government projects and that vary according to the structural characteristics of the social, cultural and political environment must also be considered. The aim of this paper is explore some determining aspects of success that affect the development of e-government of the most representative cantons in Ecuador. The result of this study has made it possible to classify municipalities according to their e-government index and has also allowed establishing a baseline of determining aspects that influence the development of municipal e-government, such as: size of the government, population density, financing, geographic location, demographic resources, among others. The main determining factors that lead to success in e-government initiatives present many differences when referring to a unified conceptual framework.
