A method for automatically establishing a wireless connection, a gateway device and a client device for internet of things (IoT) using the same are provided. According to the provided method, SSID of the gateway device can be composed of an encrypted access password and an index, so that the client device may identify the gateway device to be connected according to the index within the SSID string and acquire the encrypted access password from the SSID string. Therefore, the client device can decrypt the encrypted access password. Accordingly, the wireless connection between the client device and the gateway device can be automatically established since the client device acquires the access password from the SSID of the gateway device.

An identity verification method, an IoT gateway device, and a verification gateway device using the same are provided. According to the provided method, the IoT gateway device firstly establishes a look-up table including a valid MAC address list and a valid RSSI range of at least one valid client device. When the IoT gateway device receives the connection request sent from the client device, the IoT gateway device may obtain the MAC address and a RSSI value of the client device according to the connection request and compare the received MAC address and the received RSSI value with the valid MAC address list and the valid RSSI range, so as to determine whether the client device is the valid client device.

In this paper we consider multi-echelon multi-item channels subject to supplier's credit period and retailer's promotional effort. The retailer determines the promotional effort and the joint replenishment cycle while still maximizing profits from the perspectives of the individual and channel. We analyze two trade allowances, the promotion cost sharing and the cash discount, which are designed for coordinating the channel partner's behavior. This study provides a comparison model for each party to realize the preference of the coordinating mechanism in light of allowance ratios. Our findings show it is beneficial for both parties to have a coordinating mechanism when a promotion is conducted. © 2009 Elsevier B.V. All rights reserved.

An image fusion method and an image processing apparatus are provided. A first image is generated based on a first photographing parameter, and a second image is generated based on a second photographing parameter. A first pixel reference value of each of first pixels is calculated by using a self-define mask according to color components and a luminance component of the first pixels on the first image. A second pixel reference value of each of second pixels is calculated by using the self-define mask according to color components and a luminance component of the second pixels on the second image. A synthesizing reference map recording a plurality of synthesizing weights is obtained by comparing the first pixel reference value and the corresponding second pixel reference value. A fusion image is obtained by synthesizing the first image and the second image according to the synthesizing reference map.
