This paper analyzes the significance of the representation and reusability of SRML when being used in simulation models as well as its drawbacks. The paper also discusses the ways to extend SRML schema based on DEVS. The emphasis is placed on the elaboration of mapping DEVS onto SRML schema to formulate SRML's basic sy... | ['Chen Liu', 'Qun Li', 'Weiping Wang', 'Yifan Zhu'] | Extend SRML schema based on DEVS: an executable DEVS language | 152,368 |
Abstract#R##N#Effective nuclear charges of the main group elements from the second up to the fifth row have been developed for the one-electron part of the spin-orbit (SO) coupling Hamiltonian. These parameters, suitable to be used for SO calculations of large molecular systems, provide a useful and remarkably good app... | ['Sandro Chiodo', 'Nino Russo'] | One‐electron spin‐orbit contribution by effective nuclear charges | 24,025 |

We introduce a framework for construction of non-separable multivariate splines that are geometrically tailored for general sampling lattices. Voronoi splines are B-spline-like elements that inherit the geometry of a sampling lattice from its Voronoi cell and generate a lattice-shift-invariant spline space for approxim... | ['Mahsa Mirzargar', 'Alireza Entezari'] | Voronoi Splines | 668,525 |
It seems clear that online teaching will be a growing proportion of teaching overall, both in the form of completely online courses and blended courses with significantly reduced face-to-face interaction. | ['Gregory W. Hislop'] | The Inevitability of Teaching Online | 262,090 |

This paper concerns application of feedback in LT codes. The considered type of feedback is acknowledgments, where information on which symbols have been decoded is given to the transmitter. We identify an important adaptive mechanism in standard LT codes, which is crucial to their ability to perform well under any cha... | ['Jesper Hemming Sørensen', 'Petar Popovski', 'Jan Østergaard'] | On the Role of Feedback in LT Codes | 48,521 |
As part of its many functions, the reference library is charged with developing both its collection and its user community. These two functions are sometimes pursued as separate initiatives (with separate funding) by library managers. In Australia, the State Library of Queensland (SLQ) is committed to an exciting polic... | ['Jerry Watkins', 'Angelina Russo'] | Developing communities and collections with new media and information literacy | 839,240 |
Abstract HYPERchannel [1,3,5,7] is a local network configuration with random access to the global transmission medium and with ‘Carrier Sense’ techniques. Conflicts are resolved by a fixed priority scheduling of retransmissions. This paper presents a performance evaluation of HYPERchannel access protocols for differ... | ['Otto Spaniol'] | Analysis and performance evaluation of HYPERchannel access protocols | 391,621 |
End users can create kinds of mashups which combine various data-intensive services to form new services. The challenging issue of data-intensive service mashup is how to find service from a great deal of candidate services while satisfying SLAs. In this paper, Service-Level Agreement (SLA) consists of two parts, which... | ['Wanchun Yang', 'Chenxi Zhang', 'Bin Mu'] | Data-intensive Service Mashup Based on Game Theory and Hybrid Fireworks Optimization Algorithm in the Cloud | 600,521 |
An LMS closed-loop time-delay estimator is presented. It uses the error between two samples of the incoming signal (the difference between the delayed signal and the reference signal passed through a known delay) as a performance index for the estimator. The LMS algorithm adaptively controls the delay so as to minimize... | ['Hagit Messer', 'Y. Bar-Ness'] | Closed-loop least mean square time-delay estimator | 434,513 |
Induction of predictive models is one of the most frequent data mining tasks. However, for several domains, the available data is unlabeled and the generation of a class label for each instance may have a high cost. An alternative to reduce this cost is the use of active learning, which selects instances according to a... | ['Davi Pereira dos Santos', 'André Carlos Ponce Leon Ferreira de Carvalho'] | Comparison of Active Learning Strategies and Proposal of a Multiclass Hypothesis Space Search | 310,047 |
Pedestrian navigation systems (PNS) using foot-mounted MEMS inertial sensors use zero-velocity updates (ZUPTs) to reduce drift in navigation solutions and estimate inertial sensor errors. However, it is well known that ZUPTs cannot reduce all errors, especially as heading error is not observable. Hence, the position es... | ['Muhammad Ilyas', 'Kuk Cho', 'Seung-Ho Baeg', 'Sangdeok Park'] | Drift Reduction in Pedestrian Navigation System by Exploiting Motion Constraints and Magnetic Field | 863,151 |
We propose a low hardware overhead mechanism for internal FPGA configuration check and repair. The approach is effective against soft errors in the configuration memory (i.e., the errors caused by high energy radiation also known as Single Event Upsets). The proposed recovery mechanism occupies less hardware resources ... | ['Uros Legat', 'Anton Biasizzo', 'Franc Novak'] | FPGA Soft Error Recovery Mechanism with Small Hardware Overhead | 481,294 |
In this work, we propose a web personalization methodology by detecting the user navigation’s orientation. To this goal, we track user’s hits and define whether a user specializes or generalizes his navigation through semantics analysis of the pages in his session window. An algorithm of capturing user session orientat... | ['John D.
