Cardiovascular disease (CVD) is a leading cause of death worldwide, with millions dying each year. The identification and early diagnosis CVD are critical in preventing adverse health outcomes. Hence, this study proposes hybrid deep learning (DL) model that combines convolutional neural network (CNN) long short-term memory (LSTM) to identify from the clinical data. This utilizes CNN extract relevant features input data LSTM process sequential capture dependencies patterns over time. provides...

The purification of waste engine oil was conducted utilizing locally available clay in three different forms: raw, acid-treated, and a mixture with activated charcoal. A 72.6% 70.12% efficiency has been achieved when employing raw acid-treated clay, respectively. However, the yield decreased to 64.35% combination FTIR analysis confirmed presence alkanes alkenes purified oil. NMR GC-MS identified linear branched alkenes, as well substituted-benzene compounds density corresponding determined...

Excessive heating and power loss due to high-frequency switching are always alarming issues in the case of multilevel inverter (MLI) based applications such as solar photovoltaic (PV) systems industrial drives. Both semiconductor switches significantly rely on pulse width modulation (PWM) scheme employed. This paper proposes an improved technique for a PV-fed grid-tied 5-level cascaded H-bridge (CHB) inverter, which also reduces losses relation several existing schemes. The proposed employs...
