We propose a chaotic encryption method based on Cellular Automata(CA), specifically on the family called the “Life-Like” type. Thus, the encryption process lying on the pseudo-random numbers generated (PRNG) by each CA’s evolution, which transforms the password as the initial conditions to encrypt messages. Moreover, is explored the dynamical behavior of CA to reach a “good” quality as PRNG bas...

44 EASUREMENT of patient survival is necessary for the evaluation of I treatment of usually fatal chronic diseases. This is particularly true for cancer. The American College of Surgeons, recognizing this, requires the maintenance of a cancer case registration and follow-up program for approval of a hospital cancer program.’ Acceptance of survival as a criterion for measuring the effectiveness ...

Activity monitoring using accelerometers is of growing interest. Acceleration contains information about intensity and frequency of activities. An additional barometer provides information on altitude. This paper presents an evaluation of several features with respect to their suitability for recognizing resting, walking, cycling, going upand downstairs. Two classifiers are proposed: one using ...

This paper describes a Savings Based algorithm for the Extended Vehicle Routing Problem. This algorithm is compared with a Sequential Insertion algorithm on reallife data. Besides the traditional quality measures such as total distance traveled and total workload, we compare the routing plans of both algorithms according to nonstandard quality measures that help to evaluate the "visual attracti...

It has been proved that the vital signs can be detected via radar. To better identify the life parameters such as respiration and heartbeat, a novel method combined with several signal processing techniques is presented. Firstly, to improve the signal-to-noise ratio (SNR) of the life signals, the signal accumulation technique by FFT is used. Then, to restrain the interferences produced by movin...

The life table has been used to study mortality and survival in a population and also the pattern of course of various chronic medical illnesses. In this study, the life table has been applied to a cohort of well defined Schizophrenic patients undergoing a long term followup. The probability of occurence of relapses, time of maximum risk for occurence of relapses are estimated using the life ta...

First Executive Corporation’s bankruptcy in 1991 made the insurance policyholders, investors and regulators to concern about the solvency of life insurer in US market. As First Executive Corporation had more than 15 billion dollars in assets, its failure provoked increasing debate over the prediction system of financial distress in insurance industry, the Insurance Regulatory Information System...

Persistent online virtual environments, whether game worlds like World of Warcraft or social worlds like Second Life, provide social scientists with the opportunity to collect longitudinal behavioral profiles from users. These environments allow behavioral measures of interesting variables at the individual and group level to be collected and analyzed. For example, studies have examined mutual ...

This study investigated a non-invasive method to determine the junction temperature of AlGaInP light-emitting diodes (LEDs) in a system. Because the primary cause for the AlGaInP LED degradation is junction temperature, this method can be used to predict LED life. Currently, life estimates of LED lighting systems quoted by manufacturers (commonly 100,000 hours) are based on the average life of ...
