A multi-junction solar cell that is lattice-matched with a base, and that includes a sub-cell having a desirable band gap is provided. A plurality of sub-cells are laminated, each including first and second compound semiconductor layers. At least one predetermined sub-cell is configured of first layers and a second layer. In each of the first layers, a 1-A layer and a 1-B layer are laminated. In the second layer, a 2-A layer and a 2-B layer are laminated. A composition A of the 1-A layer and the 2-A layer is determined based on a value of a band gap of the predetermined sub-cell. A composition B of the 1-B layer and the 2-B layer is determined based on a difference between a base lattice constant of the base and a lattice constant of the composition A. Thicknesses of 1-B layer and 2-B layer are determined based on difference between base lattice constant and a lattice constant of composition B, and on thickness of the 1-A layer and thickness of 2-A layer.

Disclosed are an access authentication method and device for a WLAN hotspot. The method comprises: an access password of a WLAN hotspot is updated according to a preset update time interval; and access for a wireless workstation which is accessing to the WLAN hotspot through a soft AP is authenticated according to the updated access password. The disclosure can solve the problem in the related art that other users can use traffic without limitation once they have stolen the password which causes great damage to users who pay the bill because the access password of the WLAN hotspot can only be manually updated.

A method, computer program product, and computer system for client-server communication based on delta transfer. A server of the computer system receives from a client a HTTP request for transferring a current image page, compares the current image page and a saved image page which is stored on the server for the client. Based on the comparison, the server of the computer system constructs delta contents between the current image page and the saved image page. The server of the computer system updates the saved image page on the server with the current image page and sends a HTTP response comprising the delta contents to the client.

The present disclosure relates to methods and apparatuses for printing graphics on absorbent articles. Printing systems according to the present disclosure may include a carrier apparatus that transports individual absorbent articles past a printing station, which prints a custom graphic on the absorbent articles. The carrier apparatus may include a hook member connected with an endless belt. The printing system may also include a pressing apparatus positioned adjacent the endless belt. During operation, an absorbent article may be positioned on a hook member, and the endless belt conveys the absorbent article in the machine direction past the printing station. As the absorbent article advances toward the printing station, the pressing apparatus compresses and flattens the absorbent article against the hook member to help provide a relatively flat, smooth surface on the absorbent article to be printed. The printing station then prints a graphic on the advancing article.
