VLSI based tools for monitoring bus communication channels
An architecture for the run-time monitoring of the performance of a computer system is presented. In order to reduce the complexity of the system, a special integrated circuit has been designed, and the prototype integrated circuits are to be used in a first experimental realization of the system. The first prototype has been implemented in 3- mu m....

Using Time Warp for computer network simulations on transputers
The implementation of a Time Warp simulation frame is examined on a multitransputer machine. As computer networks can be considered as an integrated part of machine architecture, reliable evaluation tools for the development and study of protocols are a necessity. Simulation constitutes the only possible tool to obtain detailed information in this ....

A low-cost and ready to run package to transform a laptop into an advanced electrocardiograph
An electrocardiomultigraphimeter has been built which features vectorcardiography, polar coordinate tracing, automatic measurements between manually selected fiducial points and trace data filing on patient disks. The result is a package designed to work on most laptop computers that exhibits advanced clinico-scientific capabilities, as compared to....

Toward a semantics for the QUEST language
A model is given for the second-order lambda calculus extended with inheritance, bounded quantification, recursive types, constructors and kinds. This language, called mu -FunK, can be viewed as the core of the QUEST language defined by L. Cardelli (SRC Rep. 45, 1989). Types are interpreted as intervals of partial equivalence relations. Because of ....

A timestamp-based checkpointing protocol for long-lived distributed computations
The authors present a timestamp-based protocol for checkpointing the global state of a long-lived distributed computation in an environment in which processor clocks are approximately synchronized. The protocol is based on periodic checkpointing of local process states and logging of incoming messages during a short bounded interval. It tolerates p....

Variance in the solar spectrum with the position of the receiver surface during the day for PV applications
A study of the annual and daily variation in the spectral distribution of the solar irradiance and its influence on PV devices is presented. This study was performed by means of a spectral correction parameter, F which indicates the ratio between the short-circuit current (I/sub sc/) under spectral standard conditions and the measured I/sub sc/ und....

Coordinator: a basic building block for multimedia conferencing systems
An architectural model that allows the construction of multimedia conferencing environments on the basis of a set of basic building blocks is defined. A coordinator is a basic building block for designing and implementing conferencing systems. It controls the activities of a set of cooperating users. It is based on the different roles played by gro....

The impact of persistent current field errors on the stability of the proton beam in the HERA proton ring
The field error of the HERA magnets are examined with reference to the stability of the proton beam. The dynamics of the proton beam under the influence of the strong persistent field errors and the correction and compensation scheme of HERA is presented and discussed. It is concluded that the field quality of the HERA superconducting magnets is re....

Successive correlation based Prony modeling very low SNR behavior analysis
The efficiency of the higher-order correlation function as a means to extract sinusoids from white noise with the help of Prony modeling is studied. An improved white-noise-estimation approach is given. It is shown that it is unsatisfactory for low SNR and high order. A statistical analysis is given of the probability of success of the Prony-based ....
