Abstract: The present subject matter relates to size estimation of a plurality of user stories for agile software development. The plurality of user stories associated with a software may be obtained, and a base size for each of the plurality of user stories may be computed based on at least one basic parameter. The at least one basic parameter is indicative of a parameter affecting complexity associated with execution of a user story. Subsequently, an additional size for the plurality of user stories may be ascertained, based on at least one additional parameter. The at least one additional parameter is indicative of an environmental factor affecting delivery of the software. The overall size of the plurality of user stories is determined by consolidating the base size for each user story with the additional size for the plurality of user stories.

Abstract: A thermoelectric composite includes a plurality of particles comprising a crosslinked polymer having a heat deflection temperature greater than or equal to 200° F. and a segregated network comprising a first filler material which is disposed between the particles to produce a thermoelectric response in response to application of a voltage difference or temperature difference across the thermoelectric composite. The first filler material includes a carbon material, a metal, a metal disposed on a carbon material, or a combination thereof. A process for preparing a thermoelectric article includes combining a first filler material and a plurality of particles comprising a polymer to form a composition and molding the composition to form a thermoelectric article, wherein the thermoelectric article is configured to produce a thermoelectric response in response to application of a voltage difference or temperature difference across the article.

Abstract: An electric submersible well pump assembly includes a pump and an electrical motor filled with a dielectric lubricant. A capsule extends around a portion of the motor, defining a chamber between the capsule and the motor. A port through a side wall of the motor communicates the lubricant within the motor to the chamber. Thermoelectric devices are located within the chamber. Voltage supplied to the thermoelectric devices cools the lubricant.
