The Input or Arrival Process •The input process is usually called the arrival process. •Arrivals are called customers. •We assume that no more than one arrival can occur at a given instant. •If more than one arrival can occur at a given instant‚ we say that bulk arrivals are allowed. •Models in which arrivals are drawn from a small population are called finite source models. •If a customer arrives but fails to enter the system‚ we say that the customer has balked The Output or Service

Introduction: This study aims to come up with an enrollment system for a high school whichalso includes information pertinent data such as name‚ year‚ section‚ miscellaneous fees‚etc. This system is design for the use of the staff to enable them to produce informationrequired by different people. The system will make the work of faculty and staff faster‚ easier and morecomprehensive. The Enrollment System will also store the data of the students such asname‚ section‚ schedule and fees paid.

fails to consider psychological effects such as past experiences and anxiety that can act to alter pain perception (Melzack and Katz 2006). The Gate Control Theory emphasised a ‘gate mechanism’ at the dorsal horns of the spine to modulate synaptic input to the brain for processing (Melzack 2003). The gates opening is determined by the diameter of the active peripheral axons whilst the dynamic action of the brain acts to ‘close’ the gate (Keefe et al. 1996). This theory is effective in combining peripheral
