[Subject Matter] To provide a printed wiring board in which no warping occurs even if interlayer insulation layers without core material are laminated on a core substrate.[Solution(s)] To lower the thermal expansion coefficient (CTE) to 20˜40 ppm, inorganic particles are added to core substrate 30 formed by impregnating glass-cloth core material with glass-epoxy resin. Furthermore, thickness (a) of core substrate 30 is set at 0.2 mm, thickness (b) of upper-surface-side first interlayer insulation layer (50A) at 0.1 mm, and thickness (c) of lower-surface-side second interlayer insulation layer (50B) at 0.1 mm.

In a radio network environment, reducing interference among overlapping cells
Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes. If the macrocell detects that one of its cell-center users is “close enough” to the femtocell, then the macrocell re-assigns the cell-center user as a cell-edge user to overcome interference. |

Electronic camera, computer readable medium recording imaging control program thereon and imaging control method
Determination is made whether or not a cross point coordinate of a zoom value and a degree of luminance belongs to the continuous imaging area of a two-dimensional coordinate plane. When the cross point coordinate is in a single imaging area, since the provability of shake occurrence is low, a first imaging processing is operated. In contrast, when the cross point coordinate is in the continuous imaging area, a shake correction flag representing the execution of the shake correction is set. A multiplane addition composition imaging is not performed uselessly under an imaging condition where the provability of shake occurrence is low. As a result, since the multiplane addition composition imaging is not performed without inevitability, it is possible to avoid a disadvantage that a useless addition processing is executed to thereby generate noise in a shot image stored in an image memory medium. |

Client-adjustable window size for connectionless transfer protocols
Described herein are various principles for operating transfer protocols using adaptive flow control techniques. In accordance with some of these principles, a client may adaptively negotiate with a server regarding a window size to use when communicating datagrams using a connectionless content unit transfer protocol like the Trivial File Transfer Protocol (TFTP). In some implementations, a client may inform a server whether to increase or decrease a window size. In these implementations, the client may increase the window size upon determining that a previous window size has led to successful transfer of content without any loss of datagrams and the client may decrease the window size upon detecting a loss of a datagram. Because of the limited resources available in some environments in which these techniques may be used, in some implementations a window size may be increased by small amounts but may be decreased drastically upon detecting a loss. |
