Volatility and Risk: Expected Shortfall as an Alternative Risk Measure to Value at Risk (VaR)
Hamza Umar, Yussuf Kehinde Owolabi, Justice Gwatidzo
Volatility, defined as a statistical measure of dispersion of returns, is widely considered a measure of risk. Volatility in the financial markets is often associated with big swings in the returns from a given security, a portfolio of securities or a market index. Financial industries (mostly banks and insurance companies) rely on risk measures to quantify and manage these swings.
Digital transformation is the redesigning of business in the digital era. New or modified business processes and customer experiences can be created using digital technology. Think, plan, and develop digitally, and you will be more agile, versatile, and able to adapt to changes in the marketplace.
Design and Construction of a Data Transmission System Using Li-Fi Technology
Yussuf Kehinde Owolabi
Over the years, the over-dependence on Wireless Fidelity (Wi-Fi) for data transmission necessitated the need for an alternative even more reliable means of communication — Light Fidelity (Li-Fi). It involves the use of a Light Emitting Diode to transmit data by blinking (switching on and off) at a speed not noticeable to the human eye.
