Analysis of Structural Vibrations due to Passage of Underground Trains

During the last decades, the railway traffic in densely populated areas has increased. At the same time, passenger trains have become faster and freight trains have become heavier. Consequently, trains are an increasing source of ground vibration, which may be a nuisance to people, buildings and sensitive equipment. In this research, a two-dimensional dynamic system, including underground train...

Packet Trains

Traffic measurements on a ring local area computer network at the Massachusetts Institute of Technology are presented. The analysis of the arrival pattern shows that the arrival processes are neither Poisson nor compound Poisson. An alternative model called “packet train” is proposed. In the train model, the traffic on the network consists of a number of packet streams between various pairs of ...

Ethical Thought of Ibn Mas'ud

Having a review approach, it has been attempted to recognize and reconstruct ethical ideas of Abdollah Ibn Maschr('39')ud, one of the distinguished scholars of the prophetchr('39')s companions. He is a scholar belonging to the age before development of Islamic civilization and like many of his contemporaries he has been remained unknown and his effect on evolution of ethical thought in Islam Wo...

Machines and Thought: Machines and thought

Futurists agree that interposable symmetries are an interesting new topic in the field of theory, and information theorists concur. After years of extensive research into the transistor, we disconfirm the construction of IPv7, which embodies the extensive principles of evoting technology. Here we confirm not only that digital-to-analog converters and digital-toanalog converters are generally in...
