Abstract: The present invention discloses an asymmetrical PN junction thermoelectric couple structure and its parameter determination method. By changing the structural parameters of p-type semiconductor or n-type semiconductor, the current generated by p-type semiconductor is equal to the current generated by the n-type semiconductor, so that the high-efficiency output of PN junction thermoelectric couple can be realized. Meanwhile, the present invention provides a method for determining the parameters of PN junction based on the numerical solution method. Finally, the optimal size parameters of PN junction are obtained.
Abstract: In some examples, a service provider may manage inventories of items by offering money advances to make inventory orders on behalf of a merchant. The service provider may determine a risk associated with advancing money to the merchant based on sales of items made by the merchant. The service provider may provide a money advance to the merchant when the risk associated with advancing money is within a threshold level. The money advance may be used to order inventory from a supplier. This may assist the merchant in managing inventory.

Abstract: Applications in social networks support interaction between members through various types of channels such as notifications, newsfeed, and so forth. For each channel, applications are ranked based on their user affinity measures. User affinity is based on measuring positive and negative interactions by users as both senders and recipients of messages generated by applications. Metrics are computed for the different types of messages and interactions provided by applications. For each channel, an application receives user affinity score based on specific weighted combination of the metrics. Applications use channel resources to send messages to increase their user base. Given the large number of applications that are available, the extent to which applications are allowed to use channels is controlled, limiting their resource consumption. User affinity scores of applications calculated for a channel are used to decide the allocation of channel resources for an application.
