The present invention discloses a secured connector and a using process thereof. The dynamic priority of a request class is based in part on the average resource allocation to requests in this request class, and in part on settings for the minimum and maximum allocations to the request class. In one exemplary embodiment, the cable ramp has a movable lid, and at least one light source is positioned such that light emitted from the light source passes through the movable lid. The embodiments may further including applying the transform parameter to the locations of the particles within the first image to determine movement locations of the particles within the second image. In this way, it is possible to suppress deterioration of the accuracy in estimating the reference phase and amount of frequency offset by pilot symbols and improve the bit error rate characteristic in the signal to noise ratio in quasi-coherent detection with symbols whose symbol synchronization is not completely established. According to another aspect, a meta-network model is created for networks by accounting for the occurrence of network models that are found in multiple networks in a manner that reduces the redundancy across networks and that increases the specificity of the network model score.
