An Analysis and Enumeration of the Blockchain and Future Implications

The blockchain is a relatively new technology that has grown in interest and potential research since its inception. Blockchain technology is dominated by cryptocurrency in terms of usage. Research conducted in the past few years, however, reveals blockchain has the potential to revolutionize several different industries. The blockchain consists of three major technologies: a peer-to-peer network, a distributed database, and asymmetrically encrypted transactions. The peer-to-peer network enables a decentralized, consensus-based network structure where various nodes contribute to the overall network performance. A distributed database adds additional security and immutability to the network. The process of cryptographically securing individual transactions forms a core service of the blockchain and enables semi-anonymous user network presence

Multiple-compartment venting program

Computer program solves time-dependent energy and state equations for gas reservoirs, using the solutions of conductor conservation equations as mass and energy rate changes to reservoirs

Thermocouple, multiple junction reference oven

An improved oven for maintaining the junctions of a plurality of reference thermocouples at a common and constant temperature is described. The oven is characterized by a cylindrical body defining a heat sink with axially extended-cylindrical cavity a singularized heating element which comprises a unitary cylindrical heating element consisting of a resistance heating coil wound about the surface of metallic spool with an axial bore defined and seated in the cavity. Other features of the oven include an annular array of radially extended bores defined in the cylindrical body and a plurality of reference thermocouple junctions seated in the bores in uniformly spaced relation with the heating element, and a temperature sensing device seated in the axial bore for detecting temperature changes as they occur in the spool and circuit to apply a voltage across the coil in response to detected drops in temperatures of the spool

Realizability of the normal form for the triple-zero nilpotency in a class of delayed nonlinear oscillators

The effects of delayed feedback terms on nonlinear oscillators has been extensively studied, and have important applications in many areas of science and engineering. We study a particular class of second-order delay-differential equations near a point of triple-zero nilpotent bifurcation. Using center manifold and normal form reduction, we show that the three-dimensional nonlinear normal form for the triple-zero bifurcation can be fully realized at any given order for appropriate choices of nonlinearities in the original delay-differential equation.Comment: arXiv admin note: text overlap with arXiv:math/050539

Levin Visits Anna: The Iconology of Harlotry

Reader response to Anna Karenina has ranged widely over the years, with some inclined to condemn Tolstoy\u27s heroine categorically as a manipulating female and an immoral adulteress. while others have preferred to see her as a pathetic victim of her society\u27s hypocritical moral code and a noble sacrifice to her own passionate capacity for love.\u27 Whatever our final judgment of her may turn out to be, there can be little argument that Anna Karenina has indeed fallen to a pitifully low moral, spiritual and emotional state by the time she decides to commit suicide near the end of Tolstoy\u27s novel. Addicted to narcotics. psychologically unstable. and pathologically jealous, she has by now become insanely suspicious of her lover Vronsky\u27s every movement. And as her last carriage ride through Moscow makes abundantly clear, Anna is now bitterly cynical, if noc downright nihilistic, about the human condition in general. By smoking cigarettes, taking drugs. practicing birth control and refusing co breastfeed her child, she hardly qualifies. in any event, as the Tolstoyan epitome of feminine virtue or moral goodness
