This study aims to measure passengers’ perception of the importance of the four factors of check-in facility, amenities, terminal facilities, and airport accessibility facility with regard to their visit to the airport and their perceived level of performance of the particular facility and the resulting gap. Using purposive sampling method, data was collected from the departing passengers of th...
The Intelligent Parking Assistant (IPA) system helps the user chose, find and pay for parking. IPA automatically fetches parking lot information from a relevant service, automatically assesses if the vehicle is stopped, evaluates if stopped inside a payed parking lot, and automatically initiates payment for the parking. IPA is published via the MOBiNET platform: A European-wide ITS platform off...
Cloud computing has been utilising computing resources via a high bandwidth network to facilitate the execution of complicated multi-tasks that require large-scale computing. In this article, the authors propose a novel cloud multiple-function service quality survey system. The survey system will allow users to either choose one option with one category or spread their super multiple options wi...
Infinitesimal Perturbation Analysis (IPA) estimators of the response gradient for a discrete event stochastic simulation are typically developed within the framework of Generalized semi-Markov processes (GSMPs). Unfortunately, while mathematically rigorous, GSMPs are not particularly useful for modeling real systems. In this paper we describe a procedure that allows IPA gradient estimation to b...
Using an Importance}Performance Analysis (IPA), this paper examined business and leisure travellers' perceived importance and performance of six hotel selection factors in the Hong Kong hotel industry. The six hotel selection factors identi"ed were: Service Quality, Business Facilities, Value, Room and Front Desk, Food and Recreation, and Security. Both business and leisure travellers held the ...

We report our experiences with the implementation of InterProcedural Alias Analysis (IPA) for Fortran. Implicit aliasing caused by reference parameter passing can be uncovered in a program with multiple compilation units by interprocedural analysis. For scalar objects and for full arrays, the IPA processor described here finds all alias relations. For indexed array elements and partial arrays, ...
We consider resource contention games in a stochastic hybrid system setting using Stochastic Flow Models (SFM) with multiple classes and class-dependent objectives. We present a general modeling framework for such games, where Infinitesimal Perturbation Analysis (IPA) estimators are derived for the derivatives of various class-dependent objectives. This allows us to study these games from the p...
Background We evaluated the utility of galactomannan (GM) in bronchoalveolar lavage fluid (BALF) for the diagnosis of invasive pulmonary aspergillosis (IPA) in nonneutropenic patients. Methods A total of 183 patients were included in the final analysis. Bronchoscopies and the detection of GM in BALF were all performed on them. Results Ten cases of IPA were diagnosed. ROC data demonstrated t...
STUDY OBJECTIVE To assess the value of Aspergillus polymerase chain reaction (PCR) test performed on the BAL in diagnosing invasive pulmonary aspergillosis (IPA). DESIGN Between January 1996 and 1997, we prospectively followed up 249 cancer patients with pulmonary infiltrates suggestive of pneumonia. Bronchoscopy with fungal stains, cultures, and PCR was performed on all patients. PCR was use...
