A ticket dispenser (TD) is used to assist customers with the waiting process in, e.g., a restaurant. This paper deploys a mobile TD system (MTDS) with waiting time prediction to enhance the user experience while waiting. For example, the MTDS for a restaurant allows a customer to remotely draw a ticket for a meal order anywhere through a smartphone before she/he arrives at the restaurant and therefore...
With the wide adoption of cloud computing, the scientific applications are migrated to cloud for execution. The complex structure of scientific applications bring challenges to optimization scheduling scientific applications across multiple heterogeneous clouds. In this paper, the directed acyclic graphs (DAGs) are adopted to represent scientific applications, which have different priorities in the...
A ticket dispenser (TD) is used to assist customers for the waiting process in, e.g., a shop. This paper deploys a mobile ticket dispenser system (MTDS) with waiting time prediction to enhance user experience in waiting. For example, the MTDS for a restaurant allows a customer to remotely draw a ticket for meal order anywhere through a smart phone before she/he arrives at the restaurant and therefore...
In this paper, we propose the use of the modified nodal analysis (MNA) method to rederive cavity-mode equation of PCB power-bus structures with discrete capacitors. In some frequency, it shows impedance inaccuracies in the traditional double summation to calculate the transfer impedances for the studied PCB power-bus structures with discrete capacitors. Using our proposed method, we not only achieve...
This paper examines the use of wavelets to analyze EEG signals. Wavelets provide time and frequency analysis simultaneously and offer different approaches for data analysis with a number of properties and flexibility. It is intended to seek similarities and correlations of EEG signals.
Modified carboxymethyl cellulose with β-cyclodextrin (CMC-β-CDP) was prepared and the sorption properties of CMC-β-CDP towards xylenol orange (XO) were investigated. Studies concerning the effects of contact time, sorption temperature and initial XO concentration were discussed. Results of batch experiments showed that CMC-β-CDP exhibited some sorption capacities towards XO. The isotherm fitted Freundlich...
This paper considers the credit authorization problem in credit card companiespsila authorization systems. Customers are classified into several risk segments according to the type of services requested and the associated credit risk of customers. Card companies need to balance the risk exposure and the quality of customer service in the decision of referral/no referral. We formulate this problem...
