In wireless environments, data broadcast can offer unlimited mobile users up-to-date and shareable information in the meantime. Traditional schemes favor popular queries and thus sacrifice unpopular queries. This paper considers a broadcast scheduling problem, minimizing the worst access time for both popular and unpopular queries. Five useful heuristics and one anomaly are discovered, by which we can deal with this NP-hard problem properly. In our findings, the problem can be solved optimally if mobile users' access patterns present in some particular forms. Three algorithms are proposed and their near-optimality is shown in the experimental results. © 2012 Elsevier Inc. All rights reserved. Source

The purpose of this research is to explore people's intention to use telecare and evaluate the degree of influence that behavioral factors on individuals' acceptance of telecare. The subjects are residents of Taiwan. The Structural Equation Modeling (SEM) technique was used to analyze the forecasting model applied to telecare. The results show that this model has good explanatory power for the behavioral intentions of using telecare. Among factors influencing the behavioral intentions of using telecare, the strongest factor is attitude, followed by the perceived usefulness, the perceived ease of use, subjective norms, and personal innovativeness, respectively. The findings of this study may serve as a reference to future studies. © 2013 Elsevier Ltd. Source

In this study, angiotensin I-converting enzyme (ACE) inhibitory peptides, which had previously been identified in an active gelfiltration fraction from tuna cooking juice, were examined for the stability of their inhibitory properties and composition changes during processing and in the presence of gastrointestinal proteases. Results indicated that ACE inhibitory peptides reserved almost the same composition before and after various temperatures (20-100 °C), levels of pressure (50-300 MPa) and pH (2-10) treatments. ACE inhibitory peptides retained 95-99% activity after simulated digestion. High Performance Liquid Chromatography (HPLC) chromatograph peptide mappings exhibited slight differences before and after temperature (100 °C), pressure (300 MPa) and pH (2, 10) treatments. Our results indicate that tuna cooking juice-derived ACE inhibitory peptides possess some degree resistance to the influence of temperature, pressure, pH treatments, and gastrointestinal proteases. © 2010 Elsevier Ltd.

In many inventory systems, the effects of deterioration of physical goods have drawn much attention of various researchers in recent years. The more the deterioration is, the more the order quantity would be. According to such consideration, taking the deterioration rate into account is necessary. Thus, in this paper, I develop the two-warehouse partial backlogging inventory model introduced in Yang (2006) to incorporate three-parameter Weibull deterioration distribution. The objective is to derive the optimal replenishment policy that minimizes the net present value of total relevant cost per unit time. Two alternative models are compared based on the minimum cost approach. The study shows that the optimal solution not only exists but also is unique. Model 2 is still less expensive to operate than Model 1 in the proposed model. Finally, some numerical examples and sensitivity analysis on parameters are made to validate the results of the proposed inventory system. © 2012 Elsevier B.V. All rights reserved. Source

An interactive method for recording and playing data is implemented using an interactive system including a recording and playing unit, a processing unit, an RFID reader, and a memory. The method includes: a) configuring the processing unit to receive a record/stop request signal; b) configuring the processing unit to determine whether to activate the RFID reader; c) configuring the processing unit to activate the RFID reader for RFID tag reading when the processing unit determines to activate the RFID reader in step b); d) configuring the RFID reader to read a first RFID tag and to send a first identification code to the processing unit; e) configuring the processing unit to control the recording and playing unit to record data so as to generate recorded data; and f) configuring the processing unit to store the recorded data in the memory using the first identification code as an index.
