Quantum seals

A quantum seal is a way of encoding a message into quantum states, so that anybody may read the message with little error, while authorized verifiers can detect that the seal has been broken. We present a simple extension to the Bechmann-Pasquinucci majority-voting scheme that is impervious to coherent attacks, and further, encompasses sealing quantum messages by means of quantum encryption. The scheme is relatively easy to implement, requiring neither entanglement nor controlled operations during the state preparation, reading or verification stages.Comment: To appear in Physica Scripta, 4 page

Analysis of Developers Prediction Performance on Software Models Using Back Propagation Algorithm

That's what System Effort Estimation (SEE) is all about. Cost and schedule overruns are common in early phases of software development when the erroneous estimate is made. To build software development models, precise time and resource estimates are essential. Software models are typically built using a backpropagation neural network, that is the most prevalent architecture. Elman neural networks can be used in the same way as Back propagation networks. The difference between the predicted and actual effort in a successful prediction system should be as small as possible. Future training process will make use of historical NASA data. Back propagation has been found to be more effective in experiments than in Lstm neural networks. As the selections are made, the inputs' significance shifts. Comparing model test results with the model's predicted effort gives us an idea of the error rate in a model's predictions. With its help, a software project prediction model has been proposed
