Oscillators are kernel components of electrical and electronic circuits. Discussion of history, mechanisms and design based on Barkhausens observation. Discussion of a Wien Bridge oscillator based on the question: Why does this circuit oscillate ?

Over the past 30 years, there has been an increasing need to replace the current stock of bridges in Malaysia, since modern bridge systems have a lower life cost. In particular, the huge maintenance cost incurred for the expansion joints and bearings of conventional bridges has been a major concern for local state councils and authorities. The government has also acknowledged the exceptional ri...

Integral Abutment Bridges (IAB) are defined as simple or multiple span bridges in which the bridge deck is cast monolithically with the abutment walls. This kind of bridges are becoming very popular due to different aspects such as good response under seismic loading, low initial costs, elimination of bearings, and less maintenance. However the main issue related to the analysis of this type of...

Integral bridges are a class of with integral or semi-integral abutments, designed without expansion joints in the bridge deck superstructure. The significance an design is that it avoids durability and recurring maintenance issues joints, maybe bearings, which prevalent traditional bridges. less costly to construct. They require therefore cause traffic disruptions incur socio-economic costs. A...
