For a wirelessly-connected multi-robot system operating in a realistic environment, the wireless communication condition among mobile robots is generally unstable and fluctuating due to the signal loss, attenuation, multi-path fading and shadowing. This paper presents a decentralized control strategy, using the technique of reinforcement learning artificial neural network, to learn and approach a desired wireless communication coverage in a realistic environment for a team of collaborative mobile robots. A reinforcement learning neural network, based on the radial-basis function, is designed for each robot to learn the control law of maintaining the wireless link quality in a target environment and applied to the multi-robot deployment process to form communication coverage. The learning process of a robot is carried out through consecutive interactions between the controller and environment to establish the relationship between the wireless link quality and robot motion decision. In several environments simulated with the probabilistic log-distance path loss model, the simulation results show that the proposed reinforcement learning neural network based control approach leads to a desired and reliable multi-robot wireless communication coverage. © 2013 IEEE.

The underlying mixing of scalar mesons is studied in η'→ηπ π decay within a generalized linear sigma model of low-energy QCD, which contains two nonets of scalar mesons and two nonets of pseudoscalar mesons (a quark-antiquark nonet and a four-quark nonet). The model has been previously employed in various investigations of the underlying mixings among scalar mesons below and above 1 GeV (as well as those of their pseudoscalar chiral partners) and has provided a coherent global picture for the physical properties and quark substructure of these states. The potential of the model is defined in terms of two- and four-quark chiral nonets and based on the number of underlying quark and antiquark lines in each term in the potential, a criterion for limiting the number of terms at each order of calculation (and systematically further improving the results thereafter). At the leading order, which corresponds to neglecting terms in the potential with higher than eight quark and antiquark lines, the free parameters of the model have been previously fixed in detailed global fits to scalar and pseudoscalar experimental mass spectra below and above 1 GeV together with several low-energy parameters. In the present work, the same order of potential with fixed parameters is used to further explore the underlying mixings among scalar mesons in the η'→ηππ decay. It is found that the linear sigma model with only a single lowest-lying nonet is not accurate in predicting the decay width, but inclusion of the mixing of this nonet with the next-to-lowest-lying nonet, together with the effect of the final-state interaction of pions, significantly improves this prediction and agrees with the experiment up to about 1%. It is also shown that, while the prediction of the leading order of the generalized model for the Dalitz parameters is not close to the experiment, the model is able to give a reasonable prediction of the energy dependencies of the normalized decay amplitude squared and that this is expected to improve with further refinement of the complicated underlying mixings. Overall, this investigation provides further support for the global picture of scalar mesons: those below 1 GeV are predominantly four-quark states and significantly mix with those above 1 GeV, which are closer to the conventional p-wave quark-antiquark states. © 2014 American Physical Society.

The objective of jamming attacks in a network is to deny service to the communicating nodes, thus reducing network throughput and availability. In this paper, we propose a game theoretic framework for detecting jamming attacks in wireless ad hoc networks. We formulate jamming as a two-player, non-cooperative game to analyze the interaction between the attacker and the monitoring nodes in the network. We propose hybrid detection strategies at the monitor node by using cross-layer features for attack detection. We solve the game by computing the mixed-strategy Nash equilibrium and derive the optimal attack and detection strategies. Numerical results show that game theoretic analysis can be used to determine the optimal steady-state monitoring strategies to provide higher detection accuracy, while balancing the monitoring energy costs. © 2012 John Wiley & Sons, Ltd.

Throughput maximization is one of the main challenges in cognitive radio ad hoc networks, where the availability of local spectrum resources may change from time to time and hop by hop. For this reason, a cross-layer opportunistic spectrum access and dynamic routing algorithm for cognitive radio networks is proposed, which is called the routing and dynamic spectrum-allocation (ROSA) algorithm. Through local control actions, ROSA aims to maximize the network throughput by performing joint routing, dynamic spectrum allocation, scheduling, and transmit power control. Specifically, the algorithm dynamically allocates spectrum resources to maximize the capacity of links without generating harmful interference to other users while guaranteeing a bounded bit error rate (BER) for the receiver. In addition, the algorithm aims to maximize the weighted sum of differential backlogs to stabilize the system by giving priority to higher capacity links with a high differential backlog. The proposed algorithm is distributed, computationally efficient, and has bounded BER guarantees. ROSA is shown through numerical model-based evaluation and discrete-event packet-level simulations to outperform baseline solutions, leading to a high throughput, low delay, and fair bandwidth allocation. © 2006 IEEE.

Pion-pion scattering is studied in a generalized linear sigma model which contains two scalar nonets (one of quark-antiquark type and the other of diquark-antidiquark type) and two corresponding pseudoscalar nonets. An interesting feature concerns the mixing of the four isosinglet scalar mesons which yield poles in the scattering amplitude. Some realism is introduced by enforcing exact unitarity via the K-matrix method. It is shown that a reasonable agreement with experimental data is obtained up to about 1 GeV. The poles in the unitarized scattering amplitude are studied in some detail. The lowest pole clearly represents the sigma meson (or f 0(600)) with a mass and decay width around 500 MeV. The second pole invites comparison with the f 0(980) which has a mass around 1 GeV and decay width around 100 MeV. The third and fourth poles, resemble some of the isosinglet state in the complicated 1-2 GeV region. Some comparison is made to the situation in the usual SU(3) linear sigma model with a single scalar nonet. © 2011 American Physical Society.

The unusual multiplet structures associated with the light spin zero mesons have recently attracted a good deal of theoretical attention. Here we discuss some aspects associated with the possibility of getting new experimental information on this topic from semileptonic decays of heavy charged mesons into an isosinglet scalar or pseudoscalar plus leptons. © 2011 American Physical Society.

It has become clearer recently that the regular pattern of three flavor nonets describing the low spin meson multiplets seems to require some modification for the case of the spin 0 scalar mesons. One picture, which has had some success, treats the scalars in a chiral Lagrangian framework and considers them to populate two nonets. These are, in turn, taken to result from the mixing of two "bare" nonets, one of which is of quark-antiquark type and the other of two-quark-two-antiquark type. Here we show that such a mixing is, before chiral symmetry breaking terms are included, only possible for three flavors. In other cases, the two types of structure cannot have the same chiral symmetry transformation property. Specifically, our criterion would lead one to believe that scalar and pseudoscalar states containing charm would not have "four quark" admixtures. This work is of potential interest for constructing chiral Lagrangians based on exact chiral symmetry which is then broken by well-known specific terms. It may also be of interest in studying some kinds of technicolor theories. © 2011 American Physical Society.

Embedded systems are becoming extremely important technology in biomedical applications such as automatic clinical analysis and patient monitoring. The proposed device will benefit multilevel end users from collaborative medical diagnostic teams, to the patient private use at home. In this research, for heterogeneous multi-channel human body signals, different sampling rates are identified for each channel, and optimized for best data quality with minimal storage requirement. Performance evaluations show that the speed of the proposed Scheduler-on-Chip (SchoC) is 24% faster than a comparable software-based scheduler. The proposed SchoC reduces the amount of data being acquired by up to 59%, which in turn decreases memory requirements. © 2013 IEEE.

Due to a recent surge of student interest in the field of Voice over IP (VoIP) communications, new and innovative methods were required to be employed in order to keep pace with the increasing enrollment in the Voice Communications course offered at the State University of New York Institute of Technology. The traditional Voice Communications laboratory setup was obsolete and created a bottleneck hindering the students' capability to learn due to increasing class sizes. Under the previous setting, students were required to work in large groups on two shared servers in order to gain hands-on experience. This inevitably caused students to receive unequal portions of hands-on time with the allocated resources. To remedy the aforementioned issues, a centralized virtualization approach was proposed and implemented. © 2013 ACM.

A procedure for implementation of the generating equations in the linear sigma model of low energy QCD is presented. For any explicit symmetry breaking term, this procedure computes the masses of scalar and pseudoscalar mesons as well as various three-point and four-point interaction vertices that are needed in calculation of different decay widths and scattering amplitudes. © 2011 World Scientific Publishing Company.
