Forecasting international regional arrivals in Canada
… research models for forecasting tourist arrivals nationally. However, hardly any published study has tested regional international arrival forecasting accuracy. This study focuses upon forecasting arrival to the main regions of entry to Canada, using quarterly international arrival flows …

Neuro-Fuzzy Forecasting of Tourist Arrivals
… for both business and pleasure. Visitor arrivals from the 10 most popular tourist source countries to Japan, and total arrivals from all countries were used to incorporate a fairly wide variety of data patterns in the testing process. This research has established that neuro-fuzzy models …

Forecasting international regional tourist arrivals to China
… study develops models to forecast international arrivals to regional China, using time series as well as causal explanatory methods. The nine quantitative forecast methods applied in this study are Holt, Exponential Smoothing, Naïve, ARMA, Neural, and Basic Structural Model (BSM) with and without …

Queue with Random Arrivals and Exponential Service Times
Queues for service of one kind or another arise in many different fields of activity. In recent years a considerable amount of research has been conducted into the properties of simplified mathemtical models of such queuing systems. Initially, it was my aim to present a short but balanced survey of …

Centralized Wireless Networks With User Arrivals and Departures
Finally, some assumptions required for time-scale separation are relaxed. In particular, time-scale separation is extended to systems with multiple user classes, and to scheduling schemes that use residual filesize information. For the latter problem, the performance of filesize based scheduling is …

The aircraft sequencing problem with arrivals and departures
… the Aircraft Sequencing Problem (ASP) with Arrivals and Departures. The ASP is the problem of sequencing the arriving and departing aircraft on a single nmway to minimize certain performance criteria. We focus on minimizing the total weighted delay. Both the theoretical aspects of the …

Optimization of headway, stops, and time points considering stochastic bus arrivals
With the capability to transport a large number of passengers, public transit acts as an important role in congestion reduction and energy conservation. However, the quality of transit service, in terms of accessibility and reliability, significantly affects model choices of transit users. …

Numerical methods for multiserver discrete time queues with batch Markovian arrivals
Many physical systems are well-modeled by queueing systems in which time is slotted, the distribution of the number of entities that arrive during a slot is dependent upon the evolution of a discrete time, discrete state Markov chain, and the number of entities that may be served during a slot is …

Many-Server Queues with Time-Varying Arrivals, Customer Abandonment, and non-Exponential Distributions
This thesis develops deterministic heavy-traffic fluid approximations for many-server stochastic queueing models. The queueing models, with many homogeneous servers working independently in parallel, are intended to model large-scale service systems such as call centers and health care systems. …

Delay, Stop and Queue Estimation for Uniform and Random Traffic Arrivals at Fixed-Time Signalized Intersections
… intersection considering uniform and random arrivals in an attempt to systematically evaluate and demonstrate the assumptions and limitations of different delay estimation approaches. Specifically, the dissertation compared a theoretical vertical queuing analysis model, the queue-based models …

Creation and Simulation of a Model for a Discrete Time Buffer System with Interrupted Poisson Arrivals and Uncorrelated Server Interruptions
A mathematical model for a discrete-time buffer system with both arrival and server interruptions is developed. In this model fixed-size packets arrive at the buffer according to a Poisson distribution and are stored there until they can be transmitted over the output channel. Service times are …

Healthcare Across the Pregnancy Continuum: Nativity-Based Analysis of Medical Expenditures Among U.S.-Born, Recent Arrivals, and Established Immigrant Women
… among immigrants disaggregated by recent arrivals (<5 years) and established immigrants (≥5 years) within the context of Medicaid coverage policy for immigrants. Using 2013-2015 nationally representative MEPS data, we studied the concordance between self-reported and diagnosis-based …

Extension of the Gravity Model: A Risk Integrated Approach Towards the Impact Analysis of Mega Sports Events on Inbound Tourist Arrivals
<p>Mega sports events such as the Olympics and the FIFA World Cup are highly attended and countries compete ferociously to host such events due to their perceived long term positive effects. Inbound tourist forecasting is an important aspect of the hosting decision both for the organizing …

ΔΙΑΧΕΙΡΙΣΗ ΠΟΡΩΝ ΣΕ ΔΙΚΤΥΑ ΥΠΟΛΟΓΙΣΤΩΝ ΚΑΙ ΨΗΦΙΑΚΑ ΔΙΚΤΥΑ ΟΛΟΚΛΗΡΩΜΕΝΩΝ ΥΠΗΡΕΣΙΩΝ (ISDN)
… CAN DISTINGUISH W USER CLASSES AS WELL AS BUCK ARRIVALS AND BULLK DEPARTURES OF THE PACKETS OR CALL SETUP AND CALL CLEAR PACKETS FOR THE TWO PROBLEMS OF BUFFER AND BANDWIDTH ALLOCATION. FURTHER MORE THIS ANALYSIS ASSUMES THAT THE PROBABILITIES OF ARRIVALS AND DEPARTURES OF PACKETS OR ARRIVALS OF …

Interpretation of refraction and reflection stack data over the Brevard fault zone in South Carolina
… are studied using the refraction and reflection arrivals recovered from the Appalachian Ultradeep Core Hole (ADCOH) regional seismic Line 1. In using refracted arrivals, a new processing approach is introduced that translates refracted first arrivals from multifold seismic data into a refraction …

A ray model for head waves in a fluid-filled borehole
… generate the compressional and shear refracted arrivals, known as head waves, received from a point source on the axis of an ideal fluid-filled borehole. An impulse response is derived, and its frequency characteristics are investigated. The waves are compared to those obtained by the real axis …

A Gibbs sampling approach to maximum a posteriori time delay and amplitude estimations
… ratio, and the number of multi-path arrivals. The amplitudes and delays contain pertinent information about the geometry associated with the environment of interest. Estimating the time delays and amplitudes of select paths in a manner that is both accurate and time efficient, …
