Over the last few years, hyperspectral image data have been collected for a large number of locations over the world, using a variety of instruments for the earth observation. In addition, several new hyperspectral missions will become operational in the near future. Despite the increasing availability and large volume of hyperspectral data in many applications, ...

EDUCache simulator is developed as a learning tool for undergraduate students enrolled the computer architecture and organization course. It gives the explanations and details of the processor and exploitation of its cache memory. This paper shows a set of laboratory exercises and several case studies with examples on how to use the EDUCache simulator in ...

In this paper, the authors consider application of the AVX (Advanced Vector Extensions) technique to improve the performance of the PARFES parallel finite element solver, intended for finite element analysis of large-scale problems of structural and solid mechanics using multi-core computers. The basis for this paper was the fact that the dgemm matrix multiplication procedure ...

Modern Networks-on-Chip (NoC) systems are required to handle complex run-time traffic patterns and unprecedented applications. Data traffics of these applications are difficult to be fully comprehended at design-time so as to optimize the network design. However, it has been discovered that the majority data flows in a network are dominated by less than 10% of ...

Localization of a non-cooperative target with binary detectors is considered. A general expression for the Fisher information for estimation of target location and power is developed. This general expression is then used to derive closed-form approximations for the Cramer-Rao bound for the case of non-coherent detectors. Simulations show that the approximations are quite consistent with ...

The authors develop GPU adaptations of the Aho-Corasick and multipattern Boyer-Moore string matching algorithms for the two cases GPU-to-GPU (input to the algorithms is initially in GPU memory and the output is left in GPU memory) and host-to-host (input and output are in the memory of the host CPU). For the GPU-to-GPU case, they consider ...

The authors first explain the notion of secret sharing and also threshold schemes, which can be implemented with the Shamir’s secret sharing. Subsequently, they review social secret sharing and its trust function. In a secret sharing scheme, a secret is shared among a group of players who can later recover the secret. They review the ...

DBSCAN is a well-known density based clustering algorithm capable of discovering arbitrary shaped clusters and eliminating noise data. However, parallelization of DBSCAN is challenging as it exhibits an inherent sequential data access order. Moreover, existing parallel implementations adopt a master-slave strategy which can easily cause an unbalanced workload and hence result in low parallel efficiency. ...

Intense global competition, rapid technological change and shorter product life-cycles have transformed the current competitive environment. Organizations have faced increasing challenged in order to sustain their long-term success and prosperity. To meet those challenges, universities and firms have been forced to establish more formal and effective co-operation with each other to replace existing informal methods. ...

Stream Control Transmission Protocol (SCTP) is a new transport layer protocol, proposed by IETF in RFC 4960. In this paper, the authors have done a simulation-based comparison of important Quality of Service (QoS) parameter delay and the impact of packet loss on the throughput using SCTP and TCP Sack as a transport protocol in network ...
