    INTRODUCTION Psychologists use signal detection theory in a case when a man has to make decision in a very uncertain condition e.g. Mind estimates distance of an things in the fog. signal detection theory find out that the observer is not a passive receiver of informations instead of it he is an efficient choice maker who make choices in very complex uncertain conditions. Our mind is pushing us up to perceive the distance of a thing in fog and this perception is depending on the stimulus related to

    with a co-worker, or giving a speech. Speakers do not always communicate as successfully as they believe they do, in fact, speakers have been found to systematically overestimate their communication effectiveness. Most of the time the senders and receivers communicate successfully, but there are times when the lines of communication breakdown. In a work environment the lines of communication must remain intact because if there are any misunderstandings these misunderstandings could result in a life

    product limit estimator that is used for estimating the survival function from lifetime data [24]. The aim of this estimator is to estimate a population of patients’ survival curve from a sample. This estimator is used in addition to the Receiver-operator characteristic ROC curve to evaluate the performance of the prediction model [25-27]. Of course, if every patient is followed until death, the curve may be estimated simply by computing the fraction surviving at each time. However, in most medical studies

    electrical signal with a very exact frequency. This frequency is generally used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. Virtually all microprocessors, micro-controllers, PICs and CPU's commonly operate using a QUARTZ CRYSTAL OSCILLATOR as its frequency determining device to produce their clock waveform because as we already know, crystal oscillators provide the maximum
