The Banneker History Project: Historic Investigation of a Once Segregated School

The Banneker History Project was a service learning project in which students investigated the history of the Benjamin Banneker School, a segregated school that operated from 1915-1951 in a Midwestern college community. This article discusses the research these students conducted and the perceptions they adopted as a result of their work

Cogitator : a parallel, fuzzy, database-driven expert system

The quest to build anthropomorphic machines has led researchers to focus on knowledge and the manipulation thereof. Recently, the expert system was proposed as a solution, working well in small, well understood domains. However these initial attempts highlighted the tedious process associated with building systems to display intelligence, the most notable being the Knowledge Acquisition Bottleneck. Attempts to circumvent this problem have led researchers to propose the use of machine learning databases as a source of knowledge. Attempts to utilise databases as sources of knowledge has led to the development Database-Driven Expert Systems. Furthermore, it has been ascertained that a requisite for intelligent systems is powerful computation. In response to these problems and proposals, a new type of database-driven expert system, Cogitator is proposed. It is shown to circumvent the Knowledge Acquisition Bottleneck and posess many other advantages over both traditional expert systems and connectionist systems, whilst having non-serious disadvantages.KMBT_22

Tempête Alex du 2 octobre 2020 dans les Alpes-Maritimes : une contribution de la communauté scientifique à l’estimation des débits de pointe des crues

International audienceThe Alex storm caused particularly catastrophic floods in the Roya, Tinée and Vésubie valleys(south-eastern France) on 2 October 2020. This event will certainly serve as a reference for floodrisk management in the future and it is important to document it as far as possible, in order topreserve its memory and enable further studies. Different national services and operators havebeen involved to gather and consolidate datasets describing this event. This article presentsa contribution from the scientific community to the reconstruction of the event’s peakdischarges, conducted within the HyMeX research programme. Field cross section surveysmade it possible to obtain 32 peak discharge estimates, contributing to a detailed descriptionof the flood genesis on the main rivers and their small tributarieLa tempête Alex, qui a touché le 2 octobre 2020 les vallées de la Roya, la Tinée, et la Vésubiedans les Alpes-Maritimes, constitue un événement de référence qu’il est important de docu-menter au mieux pour en conserver la mémoire et permettre son étude ultérieure. Lesdifférents services et opérateurs de l’État se sont largement mobilisés pour acquérir et regrou-per des jeux de données décrivant cet événement. Cet article présente une contribution de lacommunauté scientifique à la reconstitution des débits de pointe des crues, conduite dans lecadre du programme de recherche HyMeX. Des relevés de sections d’écoulement ont permisd’obtenir 32 estimations de débits de pointe, contribuant à la connaissance des crues obser-vées sur les cours d’eau principaux et leurs petits affluents
