The portable generators are the main means of compensating the shortage of national electricity power as in Iraq. However, their noise causes a huge disturbance, uncomforting and loss of concentration of the nearby resident. This problem requires a solution because most shops and residential houses use generators. Covering method is a simple and relatively low cost one for reduction of generato...

Computers are deterministic devices and a computer-generated random number is a contradiction in terms. As a result, computer-generated pseudorandom numbers are fraught with peril for the unwary. We summarize much that is known about the most well-known pseudorandom number generators: congruential generators. We also provide machine-independent programs to implement the generators in any langua...

The report titled, “Technical Note 1834: Development of a Test Method to Determine Carbon Monoxide Emission Rates from Portable Generators,” presents a test method developed by the National Institute of Standards and Technology (NIST) for determining carbon monoxide (CO) emission rates from portable generators while operating in an enclosed space. NIST developed the test method under an interag...

BACKGROUND Portable electrical generators have been responsible for over 800 accidental carbon monoxide (CO) poisoning deaths in the United States from 1999-2012. OBJECTIVES Because mortality figures are typically the only data reported with regard to the adverse effects of generators, we describe a nonfatal segment of the poisoned population to further emphasize the significance of the probl...

Portable generators are commonly used during electrical service interruptions that occur following large storms such as hurricanes. Nearly all portable generators use carbon based fuels and produce deadly carbon monoxide gas. Despite universal warnings to operate these generators outside only, the improper placement of generators makes these devices the leading cause of engine related carbon mo...

Electric and magnetic field generators capable of producing high-amplitude output are not readily available. This presents difficulties for electromagnetic compatibility testing of new measurement systems where these systems are intended to operate in a particularly hostile electromagnetic environment. A portable electric and a portable magnetic field generator having high pulsed field output a...
