Contract Model with Risk Sharing in Integrated Logistical Product Support

With transformation of the defense industry and industry in general, -cost-of-ownership models in relation to high-tech products must be modified. The model must include cost sharing between the purchaser and the manufacturer. Thus, the required characteristics of high-tech products must be ensured by the purchaser and the manufacturer in cooperation, so that both partners share the risk of failure.

Energy Savings Performance Contracts (ESPC): Frequently Asked Questions

An ESPC is a working relationship between a Federal agency and an energy service company (ESCO). The ESCO conducts a comprehensive energy audit for the Federal facility and identifies improvements to save energy. The following sections present a number of frequently asked questions from ESPC end-users and stakeholders.

Length contraction: the real explanation

Relativity has many mind-bending consequences, but one of the weirdest is the idea that objects in motion get shorter. Bizarre or not, Fermilab’s Dr. Don Lincoln explains just how it works. You’ll be a believer.

Appropriations and Financing: Strategic Use of Funding for Performance Contracts

42 U.S.C. § 8253 Sections 432 and 512 (EISA of 2007) authorize agencies to use appropriations, private financing, or a combination of appropriations and private financing to comply with its requirements. With this flexibility in mind, federal agencies should evaluate funding options early and employ a strategy that optimizes the impact of existing appropriations and financing options. Maximize value to government through strategic use of appropriations and energy savings, an optimal set of infrastructure improvements that meet site needs and program objectives, and an actionable plan for sustained performance.

On generalized Ri’s contraction mappings and its applications

In this work, we improve the Ri’s fixed point theorem in Ri (Indag Math 27:85–93, 2016) by creating the φ-fixed point version of such result in metric spaces. These results generalize and extend several well-known comparable results in the literature. Several applications and some examples of our theorems are also given.

Blockchain Smart Contract Reference Framework and Program Logic Architecture for Transactive Energy Systems

This paper proposes a reference framework for a transactive energy market based on blockchain. The framework was designed based on the engineering requirements of a distribution-scale market; including participant needs, expected market transactions, and the cybersecurity constructs required to support a fair, secure and efficient market operation. It leverages the existing blockchain primitives to provide clear value propositions to the transactive market, including identity management (access control), data security (integrity), resiliency (decentralization, scalability and performance). The validity of the proposed framework is demonstrated using a real-time 5-min double-auction market. The results highlight its benefits while providing strong validation of applicability to blockchain within transactive energy systems.
