Although x86 processors have been around for a long time and are the most ubiquitous processors in the world, the amount of academic research regarding details of their performance has been minimal. Here, we introduce an x86 simulation environment, called TAXI (Trace Analysis for X86 Interpretation), and use it to present some results for eight Win32 applications. In this paper, we explain the ...

In an urban area, the demand for taxis is not always matched up with the supply. This paper proposes mining historical data to predict demand distributions with respect to contexts of time, weather, and taxi location. The four-step process consists of data filtering, clustering, semantic annotation, and hotness calculation. The results of three clustering algorithms are compared and demonstrate...

What Drives Taxi Drivers? A Field Experiment on Fraud in a Market for Credence Goods Credence goods are characterized by informational asymmetries between sellers and consumers that invite fraudulent behavior by sellers. This paper presents the results of a natural field experiment on taxi rides in Athens, Greece, set up to measure different types of fraud and to examine the influence of passen...

This paper describes two techniques to achieve conflict free automated taxi processes which have been implemented by an airport traffic simulator. The first technique is based on the transitive reduction of a given routing graph, automatically creating one-way taxiway segments that allow the application of local conflict resolution strategies, preventing aircraft from getting stuck within deadl...

Floating Car Data (FCD) has been analyzed for various purposes in past years. However, limited research about the behaviors of taking long-distance taxi rides has been made available. In this paper, we used data from over 12,000 taxis during a six-month period in Shanghai to analyze the spatiotemporal patterns of long-distance taxi trips. We investigated these spatiotemporal patterns by compari...

This paper presents an optimization model for an aircraft taxi-scheduling problem that arises on the surface of airports. Though formulations are already available for this problem in the literature, they either ignore aircraft type or do not include all the safety constraints that are required to keep any two aircraft separated by a minimum distance at any time instant. The proposed model impr...

This study aimed to examine the practices and perceptions of motorcycle taxi drivers concerning the use of personal protective equipment (PPE), based on field research and an exploratory and descriptive qualitative approach. Thirty motorcycle taxi drivers from Jequié, Bahia State, Brazil, were interviewed. Data collection used a semi-structured interview and questionnaire. Data were analyzed us...
