Herein we introduce a straightforward, low cost, scalable, and technologically relevant method to manufacture an all‐carbon, electroactive, nitrogen‐doped nanoporous‐carbon/carbon‐nanotube composite membrane, dubbed “HNCM/CNT”. The membrane is demonstrated to function as a binder‐free, high‐performance gas diffusion electrode for the electrocatalytic reduction of CO 2 to formate. The Faradaic efficiency (FE) for the production of formate is 81 %. Furthermore, the robust structural and electrochemical properties of the membrane endow it with excellent long‐term stability.

We apply improved nucleon-nucleon potentials up to fifth order in chiral effective field theory, along with a new analysis of the theoretical truncation errors to study nucleon-deuteron (Nd) scattering and selected low-energy observables in H3,He4, and Li6. Calculations beyond second order differ from experiment well outside the range of quantified uncertainties, providing truly unambiguous evidence for missing three-nucleon forces within the employed framework. The sizes of the required three-nucleon-force contributions agree well with expectations based on Weinberg's power counting. We identify the energy range in elastic Nd scattering best suited to study three-nucleon-force effects and estimate the achievable accuracy of theoretical predictions for various observables.

Mobile Ad Hoc Networks (MANETs) are increasingly being used in various applications for civilian, commercial, and military uses. However, unique characteristics of MANETs introduce several challenges such as routing and mobility management. Nodes frequent movements make routing more difficult due to frequent topology changes. Dynamic Source Routing (DSR) routing protocol is among the common routing protocols that suffer from poor performance in highly dynamic environment. This paper presents an extensive study of the performance of DSR in heterogeneous scalable MANET that involves different nodes with different resources where no prior information about the destinations is available. The study shows that DSR performance suffers significantly over heterogeneous MANETs with respect to network sizes and resources.

10th IASTED International Conference on Parallel and Distributed computing and Networks, PDCN 2011

This paper proposes an optimization method of task-allocation for reducing contentions. There have been some attempts for optimizing task-allocation that minimizes the product of the amount of communications and the number of the communication hops. However, since those methods do not consider the occurrence of contentions, the effect has not been sufficient. The method proposed in this paper uses information of concurrent communication to estimate the effect of contentions to find the optimal task-allocation. In three environments examined on the experiments, the proposed method has shown a better effect than the existing method on two environments, tree and fat tree. On these environments, the maximum gain of performance over the existing method was about 25%. On the other hand, on a mesh environment, IBM BlueGene/L, the existing method better effect than the proposed method. As one of the reasons for this, the influence of the packet priority on the network of BlueGene/L to the behavior of the proposed method is discussed.

International Conference on High Performance computing and Simulation

As the HPC systems increase their size, performance of collective communications is becoming an important issue. Usually, decisions for which algorithm of those communications to be used are done based on statically specified thresholds of the size of messages and the number of processes. However, on recent HPC systems that are hiring Fat Tree or Torus topology as their interconnect, the network speed has become unpredictable. The main reason is the effect of contentions. This effect depends heavily on the relative locations of the compute nodes. On the other hand, to reduce the number of idle nodes, there are attempts for building job schedulers to attach compute nodes flexibly, without considering their relative positions among each other. With this policy, the network performance becomes unstable. As an approach for finding an appropriate algorithm even on such environment, a dynamic method, STAR-MPI, has been proposed. This method examines each algorithm at runtime, and uses the empirical data to choose the suitable one for the given situation. This paper first examined the effect of STAR-MPI on an environment with unstable network speed. The results of experiments on this environment showed that the dynamic approach was effective, but the cost for testing slow algorithms limited the effect. Then, the authors proposed an enhancement, in which algorithms that have been predicted relatively slow were discarded from the list of candidates. The predictions were done by using the performance models of the algorithms with the latency and the bandwidth measured at the first call of the collective communication. At this point, the effect of this enhancement shown in experimental results was not significant. However, the results showed that there was a possibility for achieving better performance by using more cost-effective way of prediction and tuning thresholds and factors used in the enhancement. © 2011 IEEE.

This report summarizes the proceedings of a workshop discussion session presentation and visualization of aspects relating to duplicated, copied, or cloned code. The main outcomes of the working session were: (a) a realization that two researchers had independently generated very similar methods for browsing and visualization clone "clusters", and (b) a list of questions for visualization, particularly in relation to how the "proximity" of clones may relate to interest in the clone. © Duplication, Redundancy, and Similarity in Software *** rights reserved.

An overview of the concept of program similarity is presented. It divides similarity into two types-syntactic and semantic-and provides a review of eight categories of methods that may be used to measure program similarity. A summary of some applications of these methods is included. The paper is intended to be a starting point for a more comprehensive analysis of the subject of similarity in programs, which is critical to understand if progress is to be made in fields such as clone detection. © Duplication, Redundancy, and Similarity in Software *** rights reserved.
