PoP or (Point of Presence) is a part of the outermost infrastructure of an ISP that is used to connect the ISP to the customer. PoP is a room which contains servers and aic conditioners. The air conditioners are used to make room remains cool and prevent servers from overheat. In most PoP out there, the operator monitors room every month in order to ensure the cool temperature. In this research, a...
This paper investigates the reliability of the Package-on-Package (PoP) under random vibration loading by experimental tests and FEM simulations. An event detector was used to monitor the PoP failure times under random vibration. A finite element model of the PoP assembly model was built in ANSYS, and the natural frequencies and modes were calculated and verified by experimental model test. The results...
Patient specific coefficients for reconstructing missing precordial leads (patient-specific single-use or PSS) show good performance but require a 12-lead ECG to start monitoring. A more convenient approach is either the use of population based coefficients (POP) or patient specific coefficients from an old 12-lead ECG (patient-specific multi-use or PSM). We used a data set of 1493 resting 12-lead...
