Abstract: Systems, methods, and computer-readable storage media are described for estimating real estate property values based on an adjusted repeat sales model using a regularized estimator. In one exemplary embodiment, a computer-implemented method calculates data for estimating the adjustments from an aggregated level to a first disaggregated level by marking a first transaction to a second transaction using a repeat sales house price index function at the aggregated level. The method also determines, using the calculated data, a regularized estimate of the deviation between the repeat sales house price index at the aggregated level and a repeat sales house price index at the first disaggregated level. The method further calculates the repeat sales house price index at the first disaggregated level based on the determined regularized estimate of the deviation from the aggregated level.

Abstract: A conduit slider for chemical and petrochemical systems, comprising a slider housing (10) which has a blockable conduit (20) and at least one slider plate (30) which can be moved into an open position and a closed position and vice versa. A sealing seat (40) is paired with the conduit (20), said sealing seat extending along the circumference of the conduit (20) and sealing against the slider plate (30) at least in the closed position during operation. The conduit slider ensures the seal between the sealing seat (40) and the slider plate (30) and allows the slider plate (30) to be installed into and removed from the slider housing (10) with a compact, portable, simple, and inexpensive design. This is achieved in that at least one circumferential groove (42) is formed in the sealing seat (40), a molded metal ring (50) with a media filling being arranged in said groove.

Abstract: The invention relates to a conduit slider for chemical and petrochemical systems, comprising a slider housing (10) which has a blockable conduit (20) and at least one slider plate (30) which can be moved into an open position and a closed position and vice versa. A sealing seat (40) is paired with the conduit (20), said sealing seat extending along the circumference of the conduit (20) and sealing against the slider plate (30) at least in the closed position during operation. The aim of the invention is to provide such a conduit slider for chemical and petrochemical systems, wherein the conduit slider ensures the seal between the sealing seat (40) and the slider plate (30) and allows the slider plate (30) to be installed into and removed from the slider housing (10) with a compact, portable, simple, and inexpensive design.

Abstract: In a method or apparatus for control of a point in time of a measurement of toner concentration in a developer mixture comprising toner and carrier, and wherein the developer mixture is mixed by a bucket roller provided with buckets, a toner concentration sensor is arranged for measurement of the toner concentration. Magnet bars are provided on the buckets, which magnet bars are interrupted in a region of the toner concentration sensor except for one of the magnet bars which is uninterrupted. The toner concentration sensor emits a sensor signal that exhibits a first pulse-shaped spike upon passage of the uninterrupted magnet bar and which has a larger amplitude compared to further pulse-spikes of smaller amplitude upon passage of the interrupted magnet bars. The sensor signal indicates the toner concentration between the pulse-shaped spikes.
