    Wind chill: how to calculate? Is there such thing as wind warmth ?

    I think the coolness you feel is just not described by convection. Evaporation of water from your skin also plays a major role in the temperature you perceive of air around you. The loss of heat through evaporation and gain/loss due to conduction together decide whether wind is cool or warm. So...

    Why do sigmoid functions work in Neural Nets?

    Hi, I have just started programming for Neural networks. I am currently working on understanding how a Backpropogation (BP) neural net works. While the algorithm for training in BP nets is quite straightforward, I was unable to find any text on why the algorithm works. More specifically, I am...

    Response delay in Capacitive Humidity Sensors

    I am using AD7150 board to measure capacitance (analog[dot]com/static/imported-files/data_sheets/AD7150.pdf). As far as I know, the board applies a excitation voltage to the capacitor and reads the charge to determine capacitance. I then scan the hex values returned by the board and convert them...

    Response delay in Capacitive Humidity Sensors

    Hello, A project I am working on currently requires me to test how capacitors in our circuit react to change in Humidity. As expected, the experimental results suggest that capacitance goes up with increasing humidity, as the electric permitivitty of air surrounding capacitor increases...

    Neutron and Photon interaction

    Talking to the point, I need to know how a free neutron interacts with light (or a photon). Or, if they do not interact, the reason behind it. The reason why I am asking this question: Assume that a free neutron is being hit by light. If I assume that light is an EM wave, I can conclude...
