Abstract: A method for coordinating a plurality of vehicles (102, 104) comprising: defining, as a command vehicle (C), a vehicle in the plurality; storing, by one or more storage devices (204) located on one or more of the vehicles (102, 104), a list of capabilities of each vehicle (102, 104); receiving, by one or more processors (202) on the command vehicle (C), a specification of a goal; based on the stored vehicle capabilities, allocating, by the one or more processors (202), to one or more of the vehicles (102, 104), one or more tasks, the one or more tasks being such that, if each of those tasks was to be performed, the goal would be accomplished; and sending, from the command vehicle (C), to each vehicle (102, 104) to which a task has been allocated, a specification of the one or more tasks allocated to that vehicle (102, 104).

Abstract: Provided are a thermoplastic polymer and a method of forming a thermoplastic polymer. The thermoplastic polymer includes a thermoplastic polymer including one or more fatty acids derived from a plant-based oil. In some embodiments, the thermoplastic polymer includes a structure according to the formula (C18HxO2)y, wherein each x is individually selected from the group consisting of 32 and 33, and wherein y is between 1 and 300. The method of forming a thermoplastic polymer including epoxidizing a plant-based oil to form an epoxidized plant-based oil; saponifying the epoxidized plant-based oil to separate the fatty acids from the glycerol; and then polymerizing the separated fatty acids to form the thermoplastic polymer.

Abstract: A coating composition comprising an aqueous dispersion of submicron natural ground calcium carbonate particles contained in a liquid binder, wherein the resultant coating may constitute either a clear coat or a glossing and opacifying coating, depending upon the presence of certain additives such as a mineral pigment (e.g., TiO2). The composition is characterised in that comprises, in the case of a clear coating, at least one ground natural calcium carbonate having a median diameter of between 0.05 and 0.15 ?m, while in the case of a glossing and opacifying coating, at least one ground natural calcium carbonate having a median diameter of between 0.05 and 0.3 ?m and at least one pigment having a refractive index of greater than or equal to 2.5.

Abstract: Devices and methods for friction stir welding using an anvil with a sacrificial material are disclosed. The method involves the steps of providing an anvil with a sacrificial material on the backside of the workpieces and operating a friction stir welding device to form a weld that joins the workpieces together with the sacrificial material. The anvil comprises a non-sacrificial base portion removably coupled with a sacrificial material.
