TL;DR: While reencounter probabilities did not differ between methods, survival estimates employing physical marking were lower than those obtained acoustically, especially between the postbreeding and the breeding period when the apparent survival of colour-banded birds was twice as low as for acoustic marking.
Abstract: Survival is a fundamental parameter in population dynamics with increasing importance in the management and conservation strategies of wildlife populations. Survival probability in vertebrates is usually estimated by live-encounter data obtained by means of physical mark-capture-recapture protocols. Non-invasive acoustic marking relying on individual-specific features of signals has been alternatively applied as a marking technique, especially in secretive species. Nevertheless, to date no research has compared survival rate estimates obtained by acoustic and physical marking. We estimated half-yearly and annual survival and recapture rates of a secretive and threatened passerine, the Dupont's lark Chersophilus duponti, using two separate live-encounter data sets of males collected simultaneously by physical and acoustic marking in the same study area. The separate analysis of both methods led to different model structures, since transient individuals had to be accounted for in the acoustic marking but not in the physical marking data set. Furthermore, while reencounter probabilities did not differ between methods, survival estimates employing physical marking were lower than those obtained acoustically, especially between the postbreeding and the breeding period when the apparent survival of colour-banded birds was twice as low as for acoustic marking. The combination of marking methods suggested the existence of different subsets of individuals differentially sampled within the population: whereas colour-banded males seemed to represent the territorial fraction of the population, both resident and floater individuals were probably detected by acoustic marking. Using traditional mark-recapture methods exclusively could have misled our estimates of survival rates, potentially affecting prospective predictions of population dynamics. Acoustic marking has been poorly applied in mark-recapture studies, but might be a powerful complement to obtain accurate estimates of fundamental demographic parameters such as survival and dispersal.
TL;DR: In this paper, a method of determining a tilt, bearing, and/or barrel rotation of a virtual marking implement with respect to a surface is presented, which is used to vary geometry of an impression profile associated with a selected physical marking implement as well as the intensity of a rendering on an electronic presentation device.
Abstract: A method of determining a tilt, bearing, and/or barrel rotation of a virtual marking implement with respect to a surface is disclosed herein. The tilt, bearing, and/or barrel rotation are used to vary geometry of an impression profile associated with a selected physical marking implement as well as the intensity of a rendering on an electronic presentation device. Further, the impression profile associated with the selected physical marking implement may change over time as marks are rendered on the electronic presentation device. More specifically, a quantity of use of the physical marking implement defines in part the size, orientation, and/or shape of one or more facets on the physical marking implement. Existing facets on the physical marking implement may be modified and/or new facets may be added to the physical marking implement as marks are rendered on the electronic presentation device.
TL;DR: In this paper, a tilt-sensitive virtual marking implement is used to render an impression on an electronic presentation device and a bearing measurement and a tilt measurement are made with respect to the surface.
Abstract: The presently disclosed technology teaches using a tilt-sensitive virtual marking implement to render an impression on an electronic presentation device. Further, a bearing measurement and a tilt measurement of the virtual marking implement are made with respect to the surface. The tilt and bearing are then used to vary geometry of an impression profile associated with the physical marking implement as well as an intensity of the rendering. A user may actively vary the impression profile while he or she produces strokes of the virtual marking implement across the surface without changing the physical marking implement selection or switching to a different virtual marking implement. When creating a rendering on a virtual canvas using the virtual marking implement and the surface, a user may wish to vary an orientation of the virtual marking implement so that a corresponding impression profile mimics an impression of a selected physical marking implement.
TL;DR: This paper argues for the necessity of specific program-based marking on the basis of levels of access stipulated by agreements, that traditional rationales for marking are still relevant, and that these rationales are subject to the contexts of specific shared print agreements.
Abstract: Shared print agreements are increasingly being used to account for space and budgetary constraints. However, there is a dearth of information in both the literature and in the available program documentation regarding quotidian, yet essential, practicalities such as additional physical marking of materials that have been committed to be retained. This paper argues for the necessity of specific program-based marking on the basis of levels of access stipulated by agreements, that traditional rationales for marking are still relevant, and that these rationales are subject to the contexts of specific shared print agreements. Lastly, it proposes a heuristic based on access to guide policy makers.

Abstract: A method for aiding construction of a building is proposed. The building includes a plurality of building components. The method comprises: (A) providing at least one building component marking attached to at least one building component, (B) providing at least one RFID tag, and C) of using at least one building component marking to identify at least one building component on the building site. An RFID tag is attached to at least one building component. The RFID tag is configured to store a predetermined location of at least one building component on a building site. A building component marking is selected from the group consisting of: an optical reflective target; and a physical marking.
