to evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an iranian population by means of cone beam ct (cbct) images.four hundred cbct images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. vertucci's classification was used to evaluate the number of roots, number of root canals, root leng...

In the building operation phase, Heating, Ventilation, and Air-Conditioning (HVAC) equipment are main contributors to excessive energy consumption unless proper design maintenance is carried out. Moreover, HVAC problems might have an impact on occupants’ discomfort in thermal comfort. Hence, identification of root cause imperative for facility managers plan preventive corrective actions. Howeve...

This study explores the methods to de-trend smooth structural break processes while conducting unit root tests. The two most commonly applied approaches for modelling breaks namely transition and Fourier functions are considered. We perform a sequence of power comparisons among alternative tests that accommodate or sharp breaks. experiments demonstrate utilizing function lead unexpected results...

In most of the security system intrusion detection system is deployed to detect and possibly prevent the attacks. Data mining methods can be used in intrusion detection system. There are several data mining methods like classification tree algoritms (C4.5), Support vector machine and so on. For a detection system to detect an attack efficiently and accurately, it must be able to reduce false po...

For critical systems design, the verification tasks play a crucial role. If abnormalities are detected, a diagnostic process must be started to find and understand the root causes before corrective actions are applied. Detection and diagnosis are notions that overlap in common speech. Detection basically means to identify something as unusual, diagnosis means to investigate its root cause. The ...
