Let's consider that we are in charge of developing an application for our travel agent in New York, and that we have decided to make use of an ontology to represent explicitly the knowledge that will be used by it. We will focus to travelling and Lodging, but leisure time, cultural events, tours, etc., will be considered in further stages of our ontology. We know that when a client makes a trip...

For migratory birds, early arrival and physical condition on the breeding grounds are important determinants of reproductive success and fitness. Differences in arrival times often exceed a month, and later arriving individuals are often in poorer condition. Habitat-specific isotopic signatures indicate that the quality of winter habitats occupied by American redstarts (Setophaga ruticilla) det...

This paper examines the impact of receiving a new stadium on team franchise values. I argue that a new stadium will increase the franchise values of teams regardless of how construction was financed. A team playing in a stadium that it owns will be able to capitalize the value of the stadium in the team’s franchise value and will thus have a higher franchise value. Using panel data for Major Le...

In this article, an Arrival and Departure Time Predictor (ADTP) for scheduling communication in opportunistic Internet of Things (IoT) is presented. The proposed algorithm learns about temporal patterns of encounters between IoT devices and predicts future arrival and departure times, therefore future contact durations. By relying on such predictions, a neighbour discovery scheduler is proposed...

Geometry-based stochastic model (GBSM) that describes the excess delay, direction of arrival, and direction of departure of multipath has been used extensively in multiple-input and multiple-output (MIMO) channel modeling. Many two dimensional and very few three dimensional (3D) GBSMs with linear array antennas have appeared in the literature. The models lack properties of the 3D channel for du...

We propose a method for tracking multiple pedestrians using a binary sensor network. In our proposed method, sensor nodes are composed of pairs of binary sensors and placed at specific points, referred to as gates, where pedestrians temporarily change their movement characteristics, such as doors, stairs, and elevators, to detect pedestrian arrival and departure events. Tracking pedestrians in ...

We consider a pedestrian tracking system where sensor nodes are placed only at specific points so that the monitoring region is divided into multiple smaller regions referred to as microcells. In the proposed pedestrian tracking system, sensor nodes composed of pairs of binary sensors can detect pedestrian arrival and departure events. In this paper, we focus on pedestrian tracking in microcell...

This paper formulates a new approach for improvement of air traffic flow management at airports, which leads to more efficient utilization of existing airport capacity to alleviate the consequences of congestion. A new model is presented, which first considers the runways and arrival and departure fixes jointly as a single system resource, and second considers arrivals and departures simultaneo...

We investigate some real-time behaviour of a (discrete time) single server system with FCFS (first come first serve) task scheduling under rush-hour conditions . The main result deals with the probability distribution of a random variable SRD(T), which describes the time the system operates without violating a fixed task service time deadline T Relying on a simple general probability model, asy...
