Abstract: A decision support tool to assist decision-making in the operation of a facility. The decision support tool allows a user to perform planning and scheduling of the events within a facility so that established economic goals do not collide with feasibility of a schedule. This is achieved by flexible time modeling, which introduces a “look-ahead” planning and scheduling technique. This technique analyzes several time periods of the schedule in light of upcoming dominant events, in order for each segment of the schedule to remain as consistent with the planning objectives as possible.

A building comprising one or more of the building assemblies is also provided.

Abstract: A decision support tool to assist decision-making in the operation of a facility. The decision support tool allows a user to perform operational programming of the facility so that the analysis of specific operational events is flexible and “on-demand.” This is achieved by allowing the user to set scope and timeframe of the analysis according to business needs. As a result, the organization can make better-informed judgments whether to add operational activities and how to adjust the ones already formulated in the program. The decision support tool can also allow for the application of strategies to communicate intent behind the programming instructions and to improve the quality of business decisions.

Abstract: Accurate and efficient detection of data duplication is implemented. A data duplication determination part (1A) of a storage system (1) temporarily stores in a pool (4) a target chunk data when a second management table (T2) indicates that the target chunk data, which is included in received data, has already been stored, and, in addition, when data (a fingerprint (FP)) for guaranteeing the identity of the target chunk data is not stored in a third management table (T3). The duplication determination part (1A), in a case where the second management table indicates that another target chunk data that differs from the target chunk is already stored, and, in addition, in a case where determination is made that the FP of the other target chunk data is stored in the third management table, makes a redetermination as to whether the chunk data stored in the pool has already been stored.

The slab has opposed dominant faces, the opposed dominant faces being at least partially wind penetrable to allow wind to flow through the packing. The at least one liquid source is oriented to direct carbon dioxide absorbent liquid into the packing to flow through the slab. The slab is disposed in a wind flow that has a non-zero incident angle with one of the opposed dominant faces. A method of carbon dioxide capture is also disclosed. Carbon dioxide absorbing liquid is applied into packing in a series of pulses. A gas containing carbon dioxide is flowed through the packing to at least partially absorb the carbon dioxide from the gas into the carbon dioxide absorbing liquid.

Abstract: An enhanced energy storage device such as double layer capacitor or battery is made starting with a substrate capable of conducting stored energy. The substrate material is one in which ordered pores can be formed, creating a template of densely arrayed pores. An electrode comprised of high density carbon nanotubes within the template is grown from and oriented substantially perpendicular to the substrate to constitute an axi-symmetric, ultra-high surface area electrode, and then the template is then selectively and only partially etched. An electrolyte is structurally confined anisotropically around the nanotubes by a remaining portion of the selectively and partially etched template so that substantially enhanced energy storage is obtained. The optimal structural confinement, which causes optimal charge storage, depends upon the amount of partial etching of the template which is defined by the electrolyte selected.

As a result, contact between the process fluid and the gas pressure changing device is avoided.

Abstract: A system to pressurize barrier fluid of a submersible installation to provide a differential pressure between the ambient pressure surrounding the submersible installation and the pressure of the barrier fluid internally in the submersible installation during submersion of the system, wherein the differential pressure fits within a predetermined differential pressure range. The system comprises a pre-charge arrangement and a pressure intensifier which is adapted to start working at a start-up pressure. The pre-charge arrangement is adapted, during submerging of the system, to provide a differential pressure within the predetermined differential pressure range until the ambient pressure equals the start up pressure of the pressure intensifier, while the pressure intensifier is adapted to provide a differential pressure within the predetermined differential pressure range when the ambient pressure equals the start-up pressure of the pressure intensifier during further submersion of the system.

Abstract: Jet impingement and two-phase cooling apparatuses with sloped vapor outlet channels are disclosed. In one embodiment, a cooling apparatus includes a fluid inlet channel, a jet orifice surface having one or more jet orifices fluidly coupled to the fluid inlet channel such that coolant fluid within the fluid inlet channel flows through the one or more jet orifices as one or more impingement jets, and a target surface. The target surface and the jet orifice surface define an impingement chamber where the one or more impingement jets impinge the target surface at an impingement region such that at least some of the coolant fluid changes to a vapor. The cooling apparatus further includes a plurality of sloped vapor outlet channels that are fluidly coupled to the impingement chamber. Coolant fluid flows through the plurality of sloped vapor outlet channels after it impinges the target surface.

Abstract: Systems and methods are provided for improving separation of gas phase streams using an adsorbent, such as 8-member ring zeolite adsorbents or DDR type zeolite adsorbents. Suitable gas phase streams can include at least one hydrocarbon, such as methane or a hydrocarbon containing at least one saturated carbon-carbon bond, and at least one additional component, such as CO2 or N2. The selectivity of the adsorbent is improved by selectivating the adsorbent with one or more barrier compounds. The presence of the barrier compounds is believed to alter the relative ability of potential adsorbates to enter into and/or move within the pores of the adsorbent.
