In this paper we suggest a modification of classical Lupanov’s method [8] that allows building circuits over the basis {&,∨,¬} for Boolean functions of n variables with size at most 2n n ( 1 + 3 log n+O(1) n ) , and with more uniform distribution of outgoing arcs by circuit gates. For almost all Boolean functions of n variables in the circuits for these functions, which are built using our meth...

OBJECTIVE Acute common iliac artery occlusion which results from blunt abdominal trauma is rare and potentially leads to a late diagnosis. METHODS We report a case of a 58-year-old patient who suffered a late diagnosed acute left common iliac artery occlusion secondary to abdominal trauma. An emergency exploratory laparotomy was performed to stop intra-abdominal bleeding, while his left limb ...

Dilatation and currettage or vaccum aspiration is an accepted method of termination of pregnancy in the fimt trimester. Search is still being made for an ideal method of termination of pregnancy in the 2nd trimester. Between 14-16 weeks of pregnancy vaginal transcervical injection of intra-amniotic saline can be done. After 16 weeks of gestation abdominal or vaginal route can be employed. Vario...

Corporate sponsorships are vital to the success of minor league sport businesses. As competition for sponsorships intensifies in these venues, there is a need for minor league sports to demonstrate a return on the sponsorship investment based on fan purchase intentions and behaviors. Prior research has identified fan involvement, goodwill, and sponsor attitudes as key predictors of fan purchase...

The starting points of this paper are two size-optimal solutions: (i) one for implementing arbitrary Boolean functions (Horne, 1994); and (ii) another one for implementing a particular sub-class of Boolean functions (Red’kin, 1970). Because VLSI implementations do not cope well with highly interconnected nets—the area of a chip grows with the cube of the fan-in (Hammerstrom, 1988)—this paper wi...

Continuously monitoring the operation of each individual fan can significantly improve the measurement quality of aerial pollutant emissions from animal buildings that have a large number of fans. To monitor the fan operation by detecting the fan vibration is a relatively new technique. A low-cost electronic vibration sensor was developed and commercialized. However, its large scale application...

Major ions and selected environmental tracers (D, 18O, 3H and chlorofluorocarbons (CFCs)) were employed to determine the source, flow rates, and hydrochemical evolution of groundwater in an alluvial fan along the front of the Qilian Mountains, which serves as an important groundwater reservoir in northwest China. Temporal and spatial variations in ion concentrations were limited near the upper ...

The distribution of airflow in a residential building varies with the periodic operation of a heating, ventilating and airconditioning (HVAC) system. Depending on the HVAC fan operation, mixing airflow (fan ON) or stratified airflow (fan OFF) occurs in the space. The objectives of this study are 1) to examine the time needed for room air to stabilize after a central ventilation fan turns ON/OFF...

This paper presents analytical fan-beam and cone-beam reconstruction algorithms that compensate for uniform attenuation in single photon emission computed tomography. First, a fan-beam algorithm is developed by obtaining a relationship between the two-dimensional (2D) Fourier transform of parallel-beam projections and fan-beam projections. Using this relationship, 2D Fourier transforms of equiv...
