Tropospheric ozone (O3) and carbon monoxide (CO) are important air pollutants and are affected by anthropogenic emissions. The relatively long atmospheric lifetimes of O3 and CO enable them to be transported over long distances from source to receptor regions. There have been significant emission reductions in North America and Europe for the past decade while the emissions from Asia have increased for the same period, with contrasting implications for the intercontinental transport of O3 and CO. In-situ measurements of O3 and CO for the period of 2001-2011 at the remote Pico mountain...

Now-a-days the bases of cryptographic systems are being challenged too frequently as the system computation tradition is fluxing its trend from small scale computation towards giant intact calculations. It demands of highly complex cryptographic nonlinear dynamic system. Chaos and cryptography have some common features, the most important being sensitivity to initial conditions, parameters and variables changes. Here we implemented chaotic behavior in signcryption to provide higher security when communicating a sensitive data over insecure network.
