On the Sensitivity Conjecture for Disjunctive Normal Forms [PDF]

open access: yes, 2016
The sensitivity conjecture of Nisan and Szegedy [CC\u2794] asks whether for any Boolean function f, the maximum sensitivity s(f), is polynomially related to its block sensitivity bs(f), and hence to other major complexity measures. Despite major advances

Envelope detector sensitivity and blocking characteristics

open access: yes2011 20th European Conference on Circuit Theory and Design (ECCTD), 2011
This paper presents analytical expressions for the sensitivity of a low power envelope detector driven by a weak RF signal in the presence of a blocking signal. The envelope detector has been proposed for low power Wake-Up radios in applications such as RFID and wireless sensor systems.

Experimental and modeling study on the effect of molecular diffusion during CO2 injection

open access: yesPetroleum Research, 2021
In this work, a new approach based on the effect of molecular diffusion on oil recovery during CO2 injection in naturally fractured reservoirs has been proposed to examine the best condition for oil recovery in the matrix block.

Sensitivity Analysis of Cumulative Oil Production and Production Rate on Block Heights and Capillary Continuity for an Iranian Carbonated Fractured Reservoir [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2009
Block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs.
