In this study, an optimal control strategy for the variable refrigerant flow (VRF) system is developed using a data-driven model and on-site data to save the building energy. Three data-based models are developed to improve the on-site applicability.

Background: Although prehospital epinephrine is frequently used in patients with out-of-hospital cardiac arrest (OHCA), its evidence is unclear. Recent studies have shown that the use of prehospital epinephrine increased the rate of return of spontan

Point-of-care ultrasound has become a useful clinical adjunct, especially in emergency medicine, because it is noninvasive, repeatable, and nonradiating. In cases of pulled elbow also known as nursemaid's elbow or radial head subluxation, diagnosis i

In this paper, we investigate the performance of multicarrier code-division multiplexing (MC-CDM) systems with minimum mean square error combining (MMSEC) over a Rayleigh fading channel. An approximated expression on the symbol error rate (SER) for M

In this paper, we first derive the theoretical performance of a complementary code keying (CCK) code on an additive white Gaussian noise (AWGN) channel and over a multipath channel. To derive the error performance, we use the weight and cross-correla

This paper considers the uncoded multiple-input multiple-output (MIMO) system with linear minimum mean square error (MMSE) detection under ideal fast fading. The distribution of SINR at the output of the MMSE detection is derived for a small number o
