In initiating communication between an accessing entity connected to an access network and a target entity connected to a data network, access from the access network to the data network is generally effected through a data-network access point and is subject to an authorisation process involving an authorisation server. The system processes pre-configured inputs and inputs collected in real time, generates a distribution optimization profile which possesses information on values of different control parameters required to keep selected components operational, by considering energy availability in the energy storage system. The composition may be used in a variety of settings, for example for topical application for treating skin diseases and skin conditions. A capacity ratio is calculated based on capacity of each of the battery blocks and the full capacity, and a remaining battery block capacity of the battery blocks is calculated based on the capacity ratio. A word line is arranged on the semiconductor substrate so as to surround the resistive zone.
