Search information on the Internet is always a tedious work. Fortunately, due to the advance of technology, it lightens the burden of the users. Many researches had shown that the Internet has fractal characteristic. In this paper, we study the possibility of applying the fractal concept for searching meaningful information on the Internet. We proposed a method to find certain images on the Internet and the results suggested that our method is very promising. © 2016 IEEE.

In this work, we mainly consider the synchronization problem of hybrid transmit-only nodes for slight modified IEEE 802.15.4 wireless sensor networks, which is called TRO 802.15.4. However, we should let the IEEE 802.15.4 networks to fit transmission cycle of transmit-only nodes in order to achieve the synchronization. The adaptive beacon interval shifting and resizing (ABISR) algorithm is then proposed to synchronize with transmit-only nodes in TRO 802.15.4. © 2017 IEEE.

The literature on ethnic theme restaurants has already shown that patrons of such restaurants often wish to experience authentic ethnic culture, and customer satisfaction correlates with authenticity. This study examines the relationship between importance and performance of perceptions of authentic dining experiences in ethnic theme restaurants, and attempts to verify the influence of authentic dining experiences on repurchase intention in ethnic theme restaurants. After designing questionnaire content and sampling, this study obtained 538 samples. The analytical results show that authentic dining experiences effectively indicate customer repurchase intention. This study thus concludes that to attract more customers, ethnic theme restaurants should improve their service, settings, and food to provide customers a more authentic dining experience. © 2011 Elsevier Ltd.

Tourism Management | Year: 2010

The content of government tourism websites is very important for promoting a tourist destination's exciting cuisine and food culture. These websites help to shape a country's, region's or locality's culinary-cultural image; they create a virtual experience for culinary tourists. This study explores the contents of the cuisine and gastronomy websites of Hong Kong, Japan, Korea, Singapore, Taiwan and Thailand, analyzing the techniques used to introduce and promote these East Asian tourist destinations' cuisine and food culture. Specifically, the researchers examined the capacity of government websites to introduce and advertise traditional and local foods, restaurants, gastronomic tours, recipes and culinary cultures (including table manners and other dining customs). They also looked more generally at culinary tourism marketing strategies, including the use of restaurant guides and certifications. © 2009 Elsevier Ltd. All rights reserved.

Wireless sensor networks based on the IEEE 802.15.4 standard is able to achieve low-power transmissions in low-rate and short-distance wireless personal area networks (WPANs). It employs the slotted carrier sense multiple access with collision avoidance (CSMA/CA) in the contention access period (CAP). Unfortunately the periodic broadcast beacon frame is transmitted without CSMA/CA so that it could be continuously collided. This type of collision causes lost synchronization and unable to join a network because the beacon frame cannot be normally received. This paper proposes a simple time shift scheme (STSS) based on IEEE 802.15.4 to keep original superframe structure and distribute transmission of beacon frame over active period to avoid beacon frame collisions. We use a simple function to allocate beacon frame transmission in the active period. The simulation results demonstrate that the proposed scheme significantly reduces the beacon collision and lost synchronization rate, and it also improves the throughput. © 2012 IEEE.


This study presents a DVCC-based voltage-controlled dual slope operation square/triangular wave generator. The proposed configuration uses two differential voltage current conveyors (DVCCs) as active building blocks with four grounded passive components. The duty cycle of the proposed square/triangular wave generator can be adjusted by an input voltage source. The circuit also exhibits an independent control of its oscillation frequency free from the signal amplitude using a grounded resistor. This study also suggests a potentiometer-tuning scheme and a dual mode operation pulse width modulator (PWM) to extend the application of the proposed circuit. This study describes the circuit operations and discusses the non-ideal characteristics and design procedures of the proposed circuits. Prototype circuits were built using commercial ICs and discrete components. Is-Spice simulation and experimental results confirm the validity of the proposed circuits. © 2012 Elsevier Ltd.

This research primarily explores the role of service innovation and customer experience in ethnic restaurants, and the relationship with customers' behavioural intention. Data were collected by means of a questionnaire distributed to 10 types of ethnic restaurants. In total, 322 samples were obtained. Statistical techniques employed include descriptive statistics, exploratory factor analysis, correlation analysis and hierarchical regression. The results suggest that service innovation has significant effects on behavioural intention and customer experience, and the mediating effect of customer experience on service innovation and customers' behavioural intention was supported. Finally, theoretical and practical implications, direction of future research and research limitations are proposed. © 2011 Taylor & Francis.

With the significant developments in wireless networks and mobile computing technology, capturing the mobile sources and locations of data have become very important information services. The new generation has relied on mobile phones tremendously in such a mobile life (M-life) with internet. In such a mobile life (M-life) with internet. Hence, a mobile phone will be a more appropriate medium for information communication better than a computer. In view of this, Google Maps and Global Positioning System (GPS) were utilized in this study, and the property of mobile Peer-to-Peer on mobile phones, to implement and construct the application of Security System for Family Members based on the Android mobile-phone platform. We propose a multi-agent interaction including the use of cooperation model and a messaging communication mechanism, which can be generated by the basic structure. Therefore, this study applies the features of information exchanged between multi-agent and mutual communication and cooperation mechanisms to mobile Peer-to-Peer system. If users could achieve distributed communication, share their personal information, and submit their own cooperation results to others, many communication situations will improve effectively in the mobile Peer-to-Peer environment. Additionally, the efficiency of the computing processes could have improved through distributed communication.

Active and Passive Electronic Components | Year: 2014

This study proposes three new sinusoidal oscillators based on an operational transresistance amplifier (OTRA). Each of the proposed oscillator circuits consists of one OTRA combined with a few passive components. The first circuit is an OTRA-based minimum RC oscillator. The second circuit is capable of providing independent control on the condition of oscillation without affecting the oscillation frequency. The third circuit exhibits independent control of oscillation frequency through a capacitor. This study first introduces the OTRA and the related formulations of the proposed oscillator circuits, and then discusses the nonideal effects, sensitivity analyses, and frequency stability of the presented circuits. The proposed oscillators exhibit low sensitivities and good frequency stability. Because the presented circuits feature low impedance output, they can be connected directly to the next stage without cascading additional voltage buffers. HSPICE simulations and experimental results confirm the feasibility of the new oscillator circuits. © 2014 Hung-Chun Chien.

A successful supply chain management (SCM) should aim to maximize the net present value of joint profits along the supply chain. However, the volatile market conditions cause the future cash flows along the supply chain more difficult to anticipate. To obtain higher supply chain value, the supplier and the retailer should cooperatively determine the optimal entry time. This paper proposes a two-stage dynamic optimization model by using a real option approach and then performs the sensitivity analyses for the option value and the investment threshold. The impacts of some critical factors, including the growth rate and the volatility of demand shock, sunk cost, and relating operational costs (cost rates, fix costs, holding costs of inventory, and shipping costs), are investigated. © 2010 Elsevier B.V.
