An electronic system includes: a second memory module; a first memory module coupled to the second memory module; and a multicast controller for managing a cache on the first memory module for the second memory module. The stainless steel consists essentially of, by weight %, C: 0. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A second light source type is mounted near the second optics area and the second light source type is mounted near the third optics areas, the second light source type having a light output level substantially lower than the light output level of the first light source type. Weighting factors are applied to the parameter in order control the relative affect each parameter has on the user’s calculated numerical.
