Abstract:
The present invention relates to a thermoelectric material. In particular, the present invention relates to a compound for an indium selenide thermoelectric element with high efficiency in which alkali and alkaline earth metal that have lower thermal conductivity and a higher Seebeck coefficient compared to common metal or semiconductors are added. According to the present invention, electrical conductivity is increased by adding alkali and alkaline earth metal to the indium selenide thermoelectric material. Therefore, thermoelectric properties of the material are enhanced.

Abstract:
PURPOSE: A method for processing a packet using a multi fault admission network fabric is provided to perform communication in an entire ring and clean a useless packet in case that fault is generated in several connection lines or nodes by using dual ring fabric. CONSTITUTION: It is judged whether a packet of the first node input terminal is normal(S601). If the packet of the first node input terminal is normal, the packet is received from the first node input terminal(S602). If the packet of the first node input terminal is not normal, it is judged whether a packet of the second node input terminal is normal(S603). If the packet of the second node input terminal is normal, the packet is received from the second node input terminal(S604). It is judged whether a target node of the packet received from the first node input terminal or the second node input terminal is a node(S605). If the target node of the packet is the node, the received packet is transmitted to a host computer attached to the node(S606). If the target node of the packet is not the node, it is judged whether the target node of the packet is a just next node of the node(S607). If the target node of the packet is the just next node of the node, the packet is cleaned(S608). If the target node of the packet is not the just next node of the node, the packet is transmitted to the next node through the first node output terminal and the second node output terminal(S609).
Abstract:
A packet processing method using a multiple fault tolerant network structure capable of performing communication of a whole ring and disusing a useless packet when a fault occurs on a plurality of connection lines and nodes by using a dual ring structure. Nodes are connected as a ring shape separately having two input lines and two output lines, and each node selects one packet after receiving two inputs and disuses the other packet and transmits the select packet through the two output lines at the same time. The present invention can solve the fault problem occurred on a multiple link or nodes, can perform network function efficiently by disusing a useless packet, accordingly it is possible to perform stable operation for several years or several decades after the network installation and decrease maintenance expenses.
