In this study, EEDI has been re-engineered by adding to the Acoustic Complexity Index (ACI) calculated for each temporal step (ACIft) and to its evenness (ACIft evenness), the evenness of ACI calculated along each frequency bin (ACItf evenness), and upgrading the ecoacoustic code (EC) from a two-digit to a three-digit code, thus increasing the analytical resolution of EEDI.
My guess would be that they were upgrading the controller code for their own (probably evil) purposes, and although they knew what they were doing would probably break some third-party controllers that weren't up to spec, that wasn't seen as a good reason to stop.
So there is an urgent need for assessment of existing buildings in terms of seismic performance and to continuously upgrade the seismic codes for the design of new buildings.
In EC-8 the improved performance for important structures such as health care facilities is not achieved as in US codes by upgrading the performance level for a given earthquake, but by increasing the hazard level through the structure importance factor (Fardis 2004).
After numerous major earthquakes, in particular that of 1963 in Bouein Zahra and 1978 in Tabas, the Iranian government began the upgrading of the code of practice for earthquake protection.
The upgrade of the code originated from the intent to investigate the complex rheological behaviour of tailings flows released following a dam failure, which till now has been the subject of relatively few studies, despite the serious consequences that the collapse of a tailings dam can induce.
Without the storm, there would be no panic-induced task force that ultimately – finally – upgraded the city's building codes.
To upgrade the performance of LDPC codes, it is necessary to avoid 4-cycles, whish is the shortest possible length for a Tanner graph.
Most officials said few changes were planned as a result of the federal decision yesterday to upgrade the terrorism alert level to code orange, the second-highest status.
Mr. Hoffman said town engineers recently reviewed Mr. Sauerwein's report to determine how to upgrade the current building to meet code.
