A multi-armed trial based on ordinal outcomes is proposed that leverages a flexible non-proportional odds cumulative logit model and numerical utility scores for each outcome to determine treatment optimality. This design uses Bayesian clustering prior the effects encourages pairwise null hypothesis of no differences between treatments. group sequential which treatments are clinically different...

Quantum systems evolving under unitary dynamics with a low rate of projective measurements can realize highly entangled steady state. However, the stability this phase against disentangling action has not been fully understood. Here, authors quantify ability to hide local quantum information, thereby relating its behavior as an emergent error-correcting code. The estimate tolerable measurement ...

Inter-symbol interference if not taken care off may cause severe error at the receiver and the detection of signal becomes difficult. An adaptive equalizer employing Recursive Least Squares algorithm can be a good compensation for the ISI problem. In this paper performance of communication link in presence of Least Mean Square and Recursive Least Squares equalizer algorithm is analyzed. A Model...

For a small sample problem with a large number of features, feature selection by cross-validation frequently goes into random tie breaking because of the discrete recognition rate. This leads to inferior feature selection results. To solve this problem, we propose using a least squares support vector regressor (LS SVR), instead of an LS support vector machine (LS SVM). We consider the labels (1...

OCDMA is a technique by which large number of users can access the network simultaneously i.e. at the same time. As the number of user increases, the dispersion and interference begin to rise, which led to high bit error rate and low quality of service of the system. Due to high bit error rate, the transmission of data becomes unsecure and error prone. Therefore to remove or minimize the disper...

Velocity errors in particle tracking velocimetry (PTV) are studied. When using high-speed video cameras, the velocity error may increase at a high camera frame rate. This increase in velocity error is due to particle-position uncertainty, which is one of the two sources of velocity errors studied here. The other source of error is particle acceleration, which has the opposite trend of diminishi...

Transmitting video data over wireless networks can be very unreliable due to packet-loss, leading to serious video quality degradation which is annoying to human perception. The lost packets not only affect the quality of current frame, but also lead to error propagation to subsequent frames due to motion-compensated prediction techniques used in standard video codecs. Adding error-resilience t...

Species evolution is essentially a random process of interaction between biological populations and their environments. As a result, some physical parameters in evolution models are subject to statistical fluctuations. In this paper, two important parameters in the Eigen model, the fitness and mutation rate, are treated as Gaussian distributed random variables simultaneously to examine the prop...
