Subgraph matching algorithms are designed to find all instances of predefined subgraphs in a large graph or network and play an important role in the discovery and analysis of so-called network motifs, subgraph patterns which occur more often than expected by chance. We present the index-based subgraph matching algorithm (ISMA), a novel tree-based algorithm. ISMA realizes a speedup compared to ...

Interstellar material (ISMa) is observed both inside and outside of the heliosphere. Relating these diverse sets of ISMa data provides a richer understanding of both the interstellar medium and the heliosphere. The galactic environment of the Sun is dominated by warm, low-density, partially ionized interstellar material consisting of atoms and dust grains. The properties of the heliosphere are ...

This paper proposes a novel multiple access scheme, which is a combination of Inhibit Sense Multiple Access (ISMA) and Frequency Division Multiple Access (FDMA). Two types of the proposed protocol are considered. They are based on FDD and TDD modes. The performance of each hybrid protocol is evaluated in terms of throughput and the comparison of the proposed schemes and the pure ISMA scheme is ...

This paper presents intelligent stereo matching algorithm (ISMA) to solve problems associated with matching stereo images. This algorithm adopts a two-dimensional Hopfield neural network (HNN) to match stereo pairs based on an energy function including three constraints referred to as uniqueness, similarity and compatibility. The similarity of a matched pair is obtained by identifying differenc...

BACKGROUND Muslims comprise 4.8% of the national population in the UK and also form a significant proportion of its ethnic minority population, with trends set to continue for the foreseeable future. With ethnic minority health inequalities deepening further, there is an apparent lack of strategies to effectively tackle this growing problem. Imams, Muslim religious leaders, represent a hitherto...

In this article we are interested of the study of the influence of capture effect to improve the performance of RFID systems, especially the time of detection of tags and collision avoidance, and by taking a comparison between four algorithms we concluded that ISMA seems to be the best one to avoid collision. Here we simulated the whole system by a direct projection of the communication systems...

The accuracy of a method [Wijnant et al., Proc. of ISMA 31, Leuven, Belgium (2010), Vol. 31] for measurement of the effective area-averaged in situ sound absorption coefficient is investigated. Based on a local plane wave assumption, this method can be applied to sound fields for which a model is not available. Investigations were carried out by means of finite element simulations for a typical...

The Appearance Models (AMs) are widely used in many applications related to face recognition, expression analysis and computer vision. Despite its popularity, the AMs are not much more accurate due to partial occlusion. Therefore, the authors have developed Robust Normalization Inverse Compositional Image Alignment (RNICIA) algorithm to solve partial occlusion problem. However, the RNICIA algor...
