Abstract: A method including executing a logical computing element (LCE) on a server. Worker LCEs are executed on the server. A first electronic file comprising geometry data in a first data structure is received at the controller LCE. An available worker LCE is identified, by the controller LCE, as an in-use worker LCE from among the worker LCEs. The geometry data is imported by the in-use worker LCE. A job instance is established by the in-use worker LCE. A rendering engine is launched by the in-use worker LCE. The rendering engine generates, for the job instance and using the geometry data, a dataset file in a second data structure different than the first data structure. The dataset file is returned by the in-use worker LCE to the controller LCE. The dataset file is returned by the controller LCE to a remote computer.

Abstract: Described herein are a method and a system to monitor one or more items offered for sale by sellers in a network-based market place. In addition to the information provided by the sellers to describe the items, interested buyers may also provide their own information to further describe the items for the benefit of the buyers.

Abstract: A fuel cell or battery for providing useful electrical power by electrochemical means, comprises: at least one cell; at least one anode and at least one cathode within said cell, and ion-conducting electrolyte means for transporting ions between the electrodes; characterised in that: fuel, oxidant and said electrolyte means are present as a mixture.

Abstract: A fuel cell or battery for providing useful electrical power by electrochemical means, comprises: at least one cell; at least one anode and at leas one cathode within said cell, and ion-conducting electrolyte means for transporting ions between the electrodes; and is characterised in that: said electrodes are porous and in that means are provided for causing hydrodynamic flow of a mixture of at least fuel and oxidant through the body of said electrodes.
