Abstract: According to examples of the disclosure there is provided a heat-driven pumping system and a method of pumping. The heat-driven pumping system comprises a closed circuit for a first liquid. The closed circuit comprises a vaporization portion. The vaporization portion is configured to receive heat from an external source. The vaporization portion is configured to cause vaporization of first liquid within the vaporization portion. Vaporization of first liquid within the vaporization portion thereby increases an amount of gas in the closed circuit. The closed circuit is sealed such that the increase in the amount of gas increases a pressure exerted on the first liquid. The heat-driven pumping system comprises a transfer means. The transfer means is configured to convert the pressure exerted on the first liquid into a pumping force. The pumping force is transferred to a pumping vessel for pumping a second liquid.

Abstract: Systems and methods for measuring and managing ambiguity among a plurality of configuration items residing in a configuration management database include determining for at least a first configuration item, at least a second configuration item such that a first set of attributes associated with the first configuration item and a second set of attributes associated with the second configuration item have at least one attribute with an identical value. As an indicator for the ambiguity, an ambiguity index for the first configuration item may be measured. One of the first configuration item and the second configuration item may be identified as an ambiguous configuration item. Upon identification, an operational state of the ambiguous configuration item or a set of one or more attributes associated with the ambiguous configuration item may be modified. The ambiguity for configuration item transactions may likewise be measured and managed to locate and resolve transaction ambiguity.

Abstract: A system and method is provided for managing verification of configuration item changes. Discovered configuration data associated with a configuration item may be received. A determination may be made regarding whether a change order for the configuration item exists. A determination may be made regarding whether the change order is in a “verification in progress” state. When the change order is in the “verification in progress” state, alignment of the discovered configuration data with the change order may be determined and a verification policy may be determined based on the determined alignment.
