for the reader who is unfamiliar with computer networks, to prepare him for reading the more detailed technical literature on the subject. The approach here is to start with an ordered list of the functions that any network must provide in tying two end users together, and then to indicate how this leads naturally to layered peer protocols out of which the architecture of a computer network is ...

Modeling and simulation are essential tools for the design and analysis of container terminals. A computer model can emulate the activities at various levels of details and capture the essential interactions among the subsystems. Analysis based on the simulation is particularly useful for designing new terminals, making modifications to existing terminals, and evaluating the benefits of new res...

The PLATO IV System based at the University of Illinois at Urbana is a highly sophisticated and very powerful approach to Computer Aided Instruction. The PLATO IV system makes use of a plasma display terminal that is a unique device with capabilities not presently found on computer terminals. A number of ARPA supported projects intend to use the plasma terminal on local connection to computer r...

The present protocol for communication between a TIP and attached terminals requires character-oriented transmission and provides for no error control. In the design of this protocol, it was apparently assumed that the majority of terminals attached to a TIP would be interactive, be normally used in a character-by-character mode both for transmission to and from the terminal, and normally suppo...

for installing a large number of sizes and types of items (e.g., machines) over time so as to optimize some measure (e.g., initial capital investment), subject to various resource constraints. Examples of this problem are scheduling the installation of point-of-sale terminals in supermarket and retail chains, and teller terminals in banks. We have formulated the installation scheduling problem ...

Power sharing among multiterminal high voltage direct current terminals (MT-HVDC) is mainly developed based on a priority or sequential manners, which uses to prevent the problem of overloading due predefined controller coefficient. Furthermore, fixed power control also suffers from an inability identify availability at rectification station. There need for that ensures efficient MT-HVDC termin...

Automatic teller machines, Internet kiosks etc. are examples of public untrusted terminals which are used to access computer systems. One of the security concerns in such systems is the so called fake terminal attack: the attacker sets up a fake terminal and fools unsuspecting users into revealing sensitive information, such as PINs or private e-mail, in their attempt to use these terminals. In...

The computer system used by the Microbiology Service of the Clinical Pathology Department, Clinical Center, National Institutes of Health is discussed. This microbiology subsystem is a part of a dedicated on-line laboratory computer system used by the entire department. The laboratory computer is connected on-line to a hospital computer which provides patient admission, transfer, and discharge ...

In this paper a new protocol is proposed for reducing the power consumption of the battery-powered terminals in a mobile computing environment. We exploit the fact that, in a mobile data network mobile terminals do not continuously receive data and therefore they need not continuously operate their receivers. Nevertheless, they need to periodically check their traffic condition, that is, whethe...

Wireless Networking is one of the fastest growing areas in the network industry today. Wireless Local Area Networks (WLANs) are gaining special interest as they provide flexibility of location along with low infrastructural and maintenance costs. The hidden terminal problem is unique to wireless networks that decrease the performance of the network. In this paper we propose a new MAC protocol t...
