Understanding purchase behavior of people in city environment can have important implications in the design and management of cities and the study of urban economy. Traditional studies have proposed to use gravity-based spatial interaction (Huff) model [1, 2] or discrete choice model [3] to model individual purchase behavior. These models treat individual purchases separately and do not explici...

In order to compute the elliptic curve point addition and doubling, unified law provides better protection against side channel attacks. One of models, providing addition, is Binary Huff Curves (BHC). Recently, a new method for BHC with improved security attacks, has been proposed. Therefore, an optimized hardware architecture in terms higher clock frequency throughput required. Consequently, t...

SEVERAL METHODS have been used to determine the life span of rat erythrocytes. Ponticorvo’ determined the detiterium content of hemin after feeding this nucide to rats and estimated the survival at 100 days. Berlin, Huff and Hennessy2 arrived at tile same estimation by determining tile turnOver of Fe59 in hemoglobin. In the same laboratory, studies with glycine-C’4tagged hemoglobin showed a mea...
