Abstract With the serious deterioration of water environment, accurate prediction quality changes has become a topic increasing concern. To further improve accuracy and stability generalization ability model, we propose new spatiotemporal forecast model to predict future quality. capture characteristics pollution data, three sites (station S1, station S2, S4) with highest temperature time serie...

We give a simplified proof of regularizing effects for first-order Hamilton-Jacobi Equations of the form ut+H(x, t, Du) = 0 in R ×(0,+∞) in the case where the idea is to first estimate ut. As a consequence, we have a Lipschitz regularity in space and time for coercive Hamiltonians and, for hypo-elliptic Hamiltonians, we also have an Hölder regularizing effect in space following a result of L. C...

In a laboratory experiment we show that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been removed. Firms are therefore forced to pay higher wages after the removal of the minimum wage than before its introduction. As a c...

A Contribution to the Empirics of Reservation Wages This paper provides evidence on the behavior of reservation wages over the spell of unemployment using high‐frequency longitudinal data. Using data from our survey of unemployed workers in New Jersey, where workers were interviewed each week for up to 24 weeks, we find that self‐reported reservation wages decline at a modest rate over the spel...

Ultra dense networks (UDN) are identified as one of the key enablers for 5G, since they can provide an ultra high spectral reuse factor exploiting proximal transmissions. By densifying the network infrastructure equipment, it is highly possible that each user will have one or more dedicated serving base station antennas, introducing the user-centric virtual cell paradigm. However, due to irregu...

Traditional acquisition methods for generating digital surface models (DSMs) of infrastructure are either low resolution and slow (total station-based methods) or expensive (LiDAR). By contrast, photogrammetric have recently received attention due to their ability generate dense 3D quickly cost. However, existing frameworks often utilize many manually measured control points, require a permanen...

Consider a (robotic) explorer starting an exploration of an unknown terrain from its base station. As the explorer has only limited communication radius, it is necessary to maintain a line of robotic relay stations following the explorer, so that consecutive stations are within the communication radius of each other. This line has to start in the base station and to end at the explorer. In the ...
