Introduction

Weighing machines have long been used for measuring weights of various objects. The basic principle behind weight measurement is balancing of force due to gravity of an object with some known standard. You could easily find weight of small objects by using standard weighing balances having pair of pans i.e. one carrying the object to be weighed and the other is used to put loads of known weights until machine is balanced. This method cannot be applied on large scales involving heavy machinery, vehicles, or even humans. Another traditional method of weighing involves balancing force of an object due ...

Sensors detect an input event and control an output event. The output often requires different timing than that of the input event. Sometimes several inputs must jointly produce an output event. In other words, logic alters the raw sensor signal so that it is directly useful for controlling local action in response to sensed events (Ouzounov et al., 2006). A sensor is an interactive application; it expresses interest in an event by defining a sensitive ‘region' and an event type. For example, if a sensor wishes to receive events directed to a geographical object, it can define its region ...

White noise entails a sound frequency that a person can hear in the form of a gentle hiss (Proakis, 2013). In essence, white noise resembles the sound heard from an ocean surf, waterfall, radio static or wind rustling through vegetation or trees. White noise affects the signal because of the electron activity, which occurs in a given medium. More specifically, the electron activity tends to increase with an increasing temperature, and this raises the noise. Too much white noise often makes it cumbersome to interpret a signal and can sometimes lead to loss of a signal.
