A New Sound-proof Pressure Chamber

A New Proof of FDR Control Based on Forward Filtration

For multiple testing problems, Benjamini and Hochberg (1995) proposed the false discovery rate (FDR) as an alternative to the family-wise error rate (FWER). Since then, researchers have provided many proofs to control the FDR under different assumptions. Storey et al. (2004) showed that the rejection threshold of a BH step-up procedure is a stopping time with respect to the reverse filtration g...

A New Vapor Pressure Equation

The Wagner equation for prediction of vapor pressure has been modified in order to improve it accuracy. On the basis of this modifications, development of a new equation for prediction of vapor pressure is outlined. Examples of the use of the equation for obtaining vapor pressure for a total of 94 pure substance are given. The proposed equation combines simplicity and accuracy and performs as w...

Weapon Chamber Pressure Measurement

Extensive testing, at pressure "'evels from 3U to 758 MPa (5,000 to 110,000 PSI) was done at Aberdeen Proving Ground to evaluate 15 different types of electrical pressure transducers used in large caliber weapons. When using a given tvoe of transducer, the ability to consistently distinguish dynamic pressure variations as small as 0.2% was demonstrated. Yet different models of pressure transduc...

A Sound and Complete Proof System

Experimental investigation on sound of a centrifugal blower and fluctuating pressure on its volute

The Research has shown that the primary sound source in centrifugal turbomachines is the blade passing frequency noise, which is caused by due to impac rotor exit flow with the volute and the wild pressure fluctuations. In this paper, a centrifugal blower with forward facing blades has been selected and the sound created by it in the output channel has been investigated in different operating c...
