In this paper, the operation smooth of the railway computer ticket system was evaluated. First, we design the evaluation index system, determine the subjective weights of the various technical indicators of the ticketing system with Fuzzy evaluation method, determine the index weight with the Entropy method, and analyze important factors affecting the system operation according to the health ev...

Telecom service providers are faced with an overwhelming flow of alarms, which makes good alarm classification and prioritisation very important. This paper first provides statistical analysis of data collected from a real-world alarm flow and then presents a quantitative characterisation of the alarm situation.

This paper describes a new type of application, which we foresee will be available on mobile devices in the future. In this paper we describe how we designed the application. The application is a parking ticket application (V-Ticket) for use on mobile devices. The application tries to match the needs of the user whilst taking into account the problems inherent in small wireless handheld devices...
