Abstract: A computer-implemented process of developing a person-level cost model for forecasting future costs attributable to claims from members of a book of business, where person-level data are available for a substantial portion of the members of the book of business for an actual underwriting period, and the forecast of interest is for a policy period is disclosed. The process uses development universe data comprising person-level enrollment data, historical base period health care claims data and historical next period claim amount data for a statistically meaningful number of individuals. The process also provides at least one claim-based risk factor for each historical base period claim based on the claim code associated with the health care claim and provides at least one enrollment-based risk factor based on the enrollment data.

Abstract: A panel antenna is provided having one or more radiating elements and a series of directors associated with each radiating element. Each series of directors is angled with respect to a direction of maximum radiation of the associated radiating element, in order to tilt the panel antenna beam. The directors may be dimensioned and/or arranged such that they couple weakly to radiation of a wavelength emitted by the associated radiating element. The directors may be dimensioned and/or arranged such that they are non-resonant at the wavelength emitted by the associated radiating element. The directors may be smaller than the length of an associated dipole radiating element.

Abstract: The method for manufacturing a single crystal semiconductor achieves an object to reduce the impurity concentration nonuniformity within a semiconductor wafer plane and thus to improve the wafer planarity by introducing an impurity into the single crystal semiconductor more uniformly during the pulling of the single crystal semiconductor from a melt. In the course of pulling the single crystal semiconductor (6), the rotating velocity (?2) of the single crystal semiconductor (6) being pulled is adjusted to a predetermined value or higher, and a magnetic field having a strength in a predetermined range is applied to the melt (5). Particularly, the crystal peripheral velocity is adjusted to 0.126 m/sec or higher, and M/V1/3 is adjusted to 35.5?M/V1/3?61.3. More desirably, the crystal peripheral velocity is adjusted to 0.141 m/sec or higher, and M/V1/3 is adjusted to 40.3?M/V1/3?56.4.

The control unit can be located adjacent to a proximal, exposed, surface of a wall. When so installed, the detection unit is located in an air space adjacent to the chimney or flue. The assembly can be removed for cleaning or maintenance.

Abstract: A computer program product is described for solving the traveling salesman problem in polynomial time. The probability distribution of the space of all paths is modeled in a configurational density distribution. A Hamiltonian is constructed specifying the costs, distance, or penalty associated with different legs of paths encompassed in the configurational density distribution. Starting at a maximum temperature where free energy dominates and the penalty function plays little role, the system is iteratively adapted to reduce the temperature in steps incrementally chosen to preserve the linear characteristic of the approximation, until a lower temperature state of reduced energy is reached in which a preferred set of paths can be identified from the configurational density distribution.
