In this research paper, the researchers consider the problem of formulating optimal and desirable policies for maintaining systems undergoing change and discuss a simple model of disk backups and other maintenance processes that include change to computer data. The researchers determine optimal strategies for scheduling such processes. A maximum entropy model of random change provides a simple and intuitive guide to the process of sector based disk change and leads to an easily computable optimum time for backup that is robust to changes in the model.
Most of governments are aware that the use of information communication tools represents a powerful means to increase collaboration and cooperation between different public institutions. The aims are to provide better and more efficient services to citizens. The ambitions of governments are to facilitate and encourage development of homogenous web-platforms providing to citizens just with one single authentication, access to several public services such as taxation service, social service, health care, etc.
It is frequently claimed that providing an effective e-government assessment framework is a necessary condition for advancing e-government. However, there are major drawbacks in many of the existing e-government frameworks and surveys, as e.g. lack of a clearly defined purpose, and that they do not allow for specific national contexts and priorities. This research paper discusses the use of e-government frameworks and benchmarking tools. The paper also reviews some of these frameworks and discusses to what extent they really can fulfill their intention in acting as guiding tools in e-government implementations.
This paper discusses how ad-hoc Personal Area Network (PAN) based on Bluetooth technology may connect to external networks. The paper assumes that the Bluetooth network (piconet) is formed by the automatic SAPIFO procedure that one or more piconet devices have access to external networks, and that IPv4 is used for external communication. Bluetooth have specified a PAN profile for IP over Bluetooth, which uses BNEP (Bluetooth Network Encapsulation Protocol) to emulate an Ethernet segments between master and slave.
