Modified condition/decision coverage is a structural coverage criterion requiring that each condition within a decision is shown by execution to independently and correctly affect the outcome of the decision. This criterion was developed to help meet the need for extensive testing of complex Boolean expressions in safety-critical applications. The paper describes the modified condition/decision...

In this paper, we design a secure transmission scheme in uplink and downlink of non-orthogonal multiple access (NOMA) system. scenario, two pairs base stationuser can operate under the presence eavesdropper. The relay plays an important role to forward signals from group stations serve distant users. However, eavesdropper overhear signal which leads performance need be reconsidered. To provide ...

IMPERFECT competition is a pervasive part of modern industrial economies, where high levels of concentration in product markets often coexist with unionised labour markets. Most standard macroeconomic models, however, assume that markets are perfectly competitive. This paper provides a simple framework in which we are able to explore some of the implications of imperfect competition for the mac...
