Real-time monitoring of photovoltaic panels

Capstone Project submitted to the Department of Engineering, Ashesi University in partial fulfillment of the requirements for the award of Bachelor of Science degree in Electrical and Electronic Engineering, May 2022With the increase in population comes the increase in demand for electricity. Day in and day out, the non-renewable sources of energy are getting depleted; thus, many countries and continents are switching to renewable energy sources. Solar energy has proven to be pollution-free and the most accessible form of renewable energy. Photovoltaic Panels (PV) Panels are the devices used to harness solar power, and they have a life span of 25 years. However, several faults can occur in the PV panel and drastically reduce the efficiency and lifespan of the Solar Panel. In this research project, a real-time monitoring system is developed to observe the emergence of any faults and put a plan of action to preserve efficiency. The system would provide both a visual and thermographic assessment of the Photovoltaic Panel. This is achieved using Internet of Things.Ashesi Universit

Global prevalence of antidepressant utilization in the community: A protocol for a systematic review

Introduction Antidepressant drugs are the most frequently prescribed medication for mental disorders. They are also used off-label and for non-psychiatric indications. Prescriptions of antidepressants have increased in the last decades, but no systematic review exists on the extent of their use in the community. Methods and analysis We will conduct a systematic review to estimate the prevalence of antidepressant use in the community. We will search for studies published from 1 January 2010 in the Embase and MEDLINE databases using a combination of controlled vocabulary and keywords adjusted for each database without any language restriction. The main inclusion criterion is the presence of prevalence data of antidepressant utilization. Thus, we will include all studies with a descriptive observational design reporting the prevalence of antidepressant use in the community. Study selection (by title/abstract and full-text screening) and data extraction for included studies will be independently conducted by pairs of reviewers. We will then synthesize the data on the prevalence of antidepressant use in individuals living in the community. If possible, we will perform a meta-analysis to generate prevalence-pooled estimates. If the data allows it, we will conduct subgroup analyses by antidepressant class, age, sex, country and other sociodemographic categories. We will evaluate the risk of bias for each included study through a quality assessment using the Joanna Briggs Institute Critical Appraisal tool: Checklist for Studies Reporting Prevalence Data. DistillerSR software will be used for the management of this review. Ethics and dissemination Ethical approval is not required for this review as it will not directly involve human or animal subjects. The findings of our systematic review will be disseminated through publications in peer-reviewed journals, the Qualaxia Network (https://qualaxia.org), presentations at international conferences on mental health and pharmacoepidemiology, as well as general public events.
