Scheduling of PCB Assembly Using Particle Swarm Optimization Algorithm
Abstract: This paper deals with the problem of scheduling ‘N’ printed circuit boards (PCBs) on a single machine equipped with an automatic component interchange mechanism. The total number of different components required to process all ‘N’ PCBs is greater than the capacity of the spool. If the essential components are not on the spool, then one or more component switches must take place earlier than the PCB can be processed. The …

Molecular Mechanisms of Drug Metabolism in Anesthesia: A Pharmacogenomic Perspective
Abstract: Pharmacogenomics studies how a person’s genetic profile affects their reaction to drugs, which is vital in anesthesia. Anesthetic pharmacology depends significantly on drug metabolism, which involves complex biochemical processes that manage the absorption, distribution, metabolism, and excretion (ADME) of anesthetic drugs. The cytochrome P450 (CYP) enzyme family plays a critical role in the metabolism of various anesthetic drugs, with genetic polymorphisms leading to inter-individual variability in drug responses. Specific CYP …

An Overview on Energy Harvesting Using Piezoelectric Material for Wi-Fi Systems
Abstract: The rapid proliferation of wireless-networked devices has intensified the demand for sustainable, maintenance-free power sources that can keep small-scale Wi-Fi modules operational in hard-to-reach or infrastructure-limited environments. This study investigates the feasibility of harvesting ambient mechanical energy using piezoelectric transduction technology and directly feeding the harvested power to a low-power Wi-Fi communication subsystem. A compact energy-harvesting module was engineered from lead-zirconate-titanate (PZT) cantilevers with resonant frequencies tuned to the dominant …

Organophilicization of Bentonite by HDTMA+ and TMPA+ Cations for Sorption of 2,4-Dichlorophenol (2,4-DCP) in Aqueous Solution
Abstract: Bentonite (Bt) was converted to organoclays by intercalation of cationic surfactants into its interlayer space. Two types of organoclays were synthesized from HDTMA and TMPA at 100% CEC, and the adsorbents were characterized by FTIR, XRD and SEM. The adsorption capacities of Bt and the organoclays for the removal of 2,4-dichlorophrnol (2,4-DCP) from aqueous solutions were tested under different conditions. Two adsorption isotherm models (Langmuir and Freundlich isotherms) were used …
