Analytical Solutions and type curves for the constant rate radial flow of fluid in both conventional and naturally fractured reservoirs including the effect of wellbore phase redistribution are presented. An automated procedure for non-linear least square minimization using the analytical solutions and their derivatives with respect to the unknown parameters developed to analyze the pressur...

In a geometry, a maximal cap is a collection of points of largest size no three of which are collinear. In AG(4, 3), maximal caps contain 20 points; the 81 points of AG(4, 3) can be partitioned into 4 mutually disjoint maximal caps together with a single point P , where every pair of points that makes a line with P lies entirely inside one of those caps. The caps in a partition can be paired up...

Sensors embedded in smart objects, machines, and buildings produce ever-growing streams of contextual data that convey information interest about their operating environment. Although an increasing number industries have embraced the utilization sensors routine operations, no clear framework is available to guide designers who aim leverage collected from these develop predictive systems. In thi...

background: during radiotherapy treatment, critical organs are shielded using lead and cerrobend blocks. the objective of this study is to compare the effects of lead and cerrobend shielding blocks on incident photon beam. methods: collimator scatter factors were measured for open square fields (3 x 3 cm to 40 x 40 cm) defined by collimator jaws and for fields blocked down to smaller asymmetric...
