ERP systems had played an important role in Taiwanese industry in the past. Nowadays, most of companies have already install traditional type of ERP. However, with the development of cloud computing recently, the scope of applying cloud computing have been gradually expanded to the enterprise information system, such as cloud CRM provided by Salesforce.com, Business by Design provided by SAP. T...

maintaining customer interest to repurchase is an important issue in today's competitive market of italian restaurants in tehran. therefore, determining the reasons that caused switching intention in customers, can be leading to arrange marketing purposes. so this research intends to evaluate effect of perceived quality, satiation and satisfaction on switching intention and to examine mode...

There has been an increasing demand for wireless data services due to the popularity of Internet services and circuit-switched (CS) systems are not appropriate for accommodating bursty data traffic. The wireless data services can be efficiently supported in the packet-switched (PS) system and General Packet Radio Service (GPRS) is a representative PS system which is being serviced widely. In GP...

This paper presents a general analytical model for studying the effect of cut-through switching on buffered MIN (multistage interconnection network) switches. We consider two types of MIN switches: input-buffered MIN and output-buffered MIN. Previous studies of cut-through switching assumed the use of 2 × 2 switching elements as a building block for the MIN; and they are not applicable to MINs ...

This paper investigates whether a regime switching model of stochastic lumber prices is better for the analysis of optimal harvesting problems in forestry than a more traditional single regime model. Prices of lumber derivatives are used to calibrate a regime switching model, with each of two regimes characterized by a different mean reverting process. A single regime, mean reverting process is...

In recent experiments, it has been shown that the switching rate of single-molecule switches can show a rather complicated dependence on the applied bias voltage. Here, we discuss a minimal model which describes the switching process in terms of inelastic scattering processes of the tunneling electron by specific molecular vibrations. One important point is the introduction of an energy-depende...

We address the problem of estimating the average switching activity of combinational circuits under random input sequences. Switching activity is strongly affected by gate delays, and for this reason we use a variable delay model in estimating switching activity. Unlike most probabilistic methods that estimate switching activity, our method takes into account correlation caused at internal gate...

In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...

This paper proposes a switching adaptive control for trajectory tracking of unmanned aircraft systems. The switching adaptive control method is designed to overcome the wind disturbance and achieve a proper tracking performance for control systems. In the suggested system, the wind disturbance is regarded as a finite set of uncertainties; a controller is designed for each uncertainty, and a per...

This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute a major portion of the total power loss at light loads. To decrease the switching losses...
