AbstractThis article discusses the diachronic development of the Spanish multifunctional formula en plan (with its variant en plan de, literally ‘in plan (of)’ but usually equivalent to English like). The article has two main aims: firstly, to describe the changes that the formula has undergone since its earliest occurrences as a marker in the nineteenth century up to the early 21st century. The diachronic study evinces a process of grammaticalization in three steps: from noun to clause adverbial and then to discourse marker. Secondly, to conduct a contrastive analysis between en plan (de) and the English markers like and kind of/kinda so as to shed new light on the potential existence of a universal pathway of grammaticalization in the emergence of discourse markers.

Marker Detection

Precise navigation is often performed by sensor fusion of different sensors. Among these sensors, optical sensors use image features to obtain the position and attitude of the camera. Runway relative navigation during final approach is a special case where robust and continuous detection of the runway is required. This paper presents a robust threshold marker detection method for monocular cameras and introduces an on-board real-time implementation with flight test results. Results with narrow and wide field-of-view optics are compared. The image processing approach is also evaluated on image data captured by a different on-board system. The pure optical approach of this paper increases sensor redundancy because it does not require input from an inertial sensor as most of the robust runway detectors.
