This paper proposes a new motivation for information sharing in a decentralized channel consisting of a single manufacturer and two competing retailers. The manufacturer provides a common product to the retailers at the same wholesale price. Both retailers add their own values to the product and distribute it to consumers. Factors such as retail prices, values added to the product, and local ad...

empowerment within an organization is an ability that provides decision making opportunity by developing the span of authority, and it caused the breakage of traditional hierarchy of organizational structure. among different dimensions of empowerment, its psychological dimension so has been considered by researchers in length of past years. knowledge sharing is one of the factors which effects ...

Microgrids are nowadays used to produce electric energy with more efficiency and advantage. However, the use of microgrids presents some challenges. One of the main problems of the microgrids widely used in electrical power systems is the control of voltage, frequency and load sharing balance among inverter- based distributed generators (DGs) in islanded mode. Droop method performance degra...

This paper studies a decentralized supply chain in which a manufacturer sells a common generic product through two traditional and online retailers under free riding market. We assume that the traditional retailer provides the value added services but the online retailer does not. Factors such as retail prices, local advertising of the retailers, global advertising of the manufacturer and servi...

Abstract For the further development and more efficient operation of sharing economy, a fast inexpensive peer-to-peer payment system is an essential element. The aim this study to outline prototype that ensures automation decentralization processes through smart contracts without blockchain technology. model has been built based on narrative community currency created can promote genuine practi...

Recently, a visual secret sharing scheme for q multiple secret images allowing the rotation of shares, a VSSq-MI-R schemes for short, is proposed by Iwamoto et al. In this paper, another definition of VSS-q-MI-R schemes is given, which is simpler than that by Iwamoto et al.

The notion of a regular anonymous perfect threshold scheme is introduced, and a combinatorial characterization for such a (2,w)-threshold scheme in terms of a regular difference family is given.  2002 Elsevier Science B.V. All rights reserved.

This note proposes a method of space efficient secret sharing in which k secrets are mapped into n shares (n ≥ k) of the same size. Since, n can be chosen to be equal to k, the method is space efficient. This method may be compared with conventional secret sharing schemes that divide a single secret into n shares.
