is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy.

Global Pharmacovigilance (PV) submissions are generally divided into ICSRs and aggregate/periodic reporting. PV submissions are increasingly done in electronic, XML based formats, across the board, not least due to the work of setting global reporting standards by the ISO and ICH. Electronic reports submitted in English are typically being handled by a central function at HQ and can to a large degree be automated via well known techniques and distributed via gateways, if the submission volumes deem this necessary.

he random arrivals of walk-in patients significantly affect the daily operations of healthcare facilities. To improve the performance of outpatient departments, this paper attempts to make an appointment schedule by considering walk-ins and the waiting time target (WTT) for appointment patients. A stochastic programming model is proposed to solve this problem with the objective of minimizing the weighted patient waiting and makespan cost. A non-decreasing waiting cost function is used to capture the WTT fulfillment of appointment patients, whereas walk-ins incur a linear waiting cost. A finite-horizon Markov Decision Process model is formulated to establish the optimal real-time scheduling policy under a given appointment schedule.
