TL;DR: An extended model to predict consumer acceptance of electronic-shopping based on the theory of reasoned action (TRA) and the technology acceptance model (TAM) confirms that perceived ease of use of trading on-line (PEOUT) and perceived usefulness (PU) significantly determine individual attitudes toward e-sh shopping, as well as confirming the significant effect of perceived easeof use of the Web on PEOUT, which in turn affects PU.

TL;DR: A hybrid forecasting model, which combines the seasonal time series ARIMA (SARIMA) and the neural network back propagation (BP) models, known as SARIMABP, was used to forecast two seasonal timeseries data of total production value for Taiwan machinery industry and the soft drink time series.

Abstract: This paper investigates the power mode management problem for an IEEE 802.11-based mobile ad hoc network (MANET) that allows mobile hosts to tune to the power-saving (PS) mode. There are two major issues that need to be addressed in this problem: (a) wakeup prediction and (b) neighbor discovery. The former is to deliver buffered packets to a PS host at the right time when its radio is turned on. The latter is to monitor the environment change under a mobile environment. One costly, and not scalable, solution is to time-synchronize all hosts. Another possibility is to design asynchronous protocols as proposed by Tseng et al. in [25]. In this paper, we adopt the latter approach and correlate this problem to the quorum system concept. We identify a rotation closure property for quorum systems. It is shown that any quorum system that satisfies this property can be translated to an asynchronous power-saving protocol for MANETs. Thus, the result bridges the classical quorum system design problem in the area of distributed systems to the power mode management problem in the area of mobile ad hoc networks. We derive a lower bound for quorum sizes for any quorum system that satisfies the rotation closure property. We identify a group of quorum systems that are optimal or near optimal in terms of quorum sizes, which can be translated to efficient asynchronous power-saving protocols. We also propose a new e-torus quorum system, which can be translated to an adaptive protocol that allows designers to trade hosts' neighbor sensibility for power efficiency. Simulation experiments are conducted to evaluate and compare the proposed protocols.

TL;DR: The intention of this paper is to provide business which are affected by diversified management with a new method to conduct short-term forecasting with a fuzzy seasonal ARIMA (FSARIMA) forecasting model, which includes both interval models with interval parameters and the possible distribution of future value.
