This paper presented a new prediction model for Pressure-Volume-Temperature (PVT) properties based on the recently introduced learning algorithm called Sensitivity Based Linear Learning Method (SBLLM) for two-layer feedforward neural networks. PVT properties are very important in the reservoir engineering computations. The accurate determination of these properties such as bubble-point pressure and oil formation volume factor is important in the primary and subsequent development of an oil field. In this work, we develop Sensitivity Based Linear Learning method prediction model for PVT properties using two distinct databases, while comparing forecasting performance, using several kinds of evaluation criteria and quality measures, with neural network and the three common empirical correlations. Empirical results from simulation show that the newly developed SBLLM based model produced promising results and outperforms others, particularly in terms of stability and consistency of prediction. ©2010 IEEE.

Local unambiguous discrimination with remaining entanglement

A bipartite state, which is secretly chosen from a finite set of known entangled pure states, cannot immediately be useful in standard quantum information processing tasks. To effectively make use of the entanglement contained in this unknown state, we introduce a way to locally manipulate the original quantum system: either identify the state successfully or distill some pure entanglement. Remarkably, if many copies are available, we show that any finite set of entangled pure states, whether orthogonal or not, can be locally distinguished in this way, which further implies that pure entanglement can be deterministically extracted from unknown entanglement. These results make it clear why a large class of entangled bipartite quantum operations including unitary operations and measurements that are globally distinguishable can also be locally distinguishable: They can generate pure entanglement consistently.

This paper presents a smoothing technique for the output sequence of linear feedback shift registers (LFSR) to reduce power consumption in test-per-scan built-in self-test (BIST) applications. The proposed smoother is implemented by adding one multiplexer between the LFSR and scan-chain input of a single scan-chain. The size of the multiplexer is determined the desired smoothing degree. When the smoothed sequence of the LFSR is used to feed the test patterns in test-per-scan BIST, it reduces the number of transitions that occur at scan-chain input during scan shift operations by 25% to 50% depending on the smoothing degree, and hence reduces switching activity in the circuit-under-test (CUT) during test application. The proposed technique can be extended to multiple scan-chains BIST, also to test-per-clock applications. Various properties of the proposed technique and the methodology of the design are presented in this paper. Experimental results for the ISCAS'89 benchmark circuits show that the proposed design can reduce the switching activity up to 55% with a negligible effect on the fault coverage and test application time.

Data mining algorithms have been proved to be useful for the processing of large data sets in order to extract relevant information and knowledge. Such algorithms are also important for analyzing data collected from the users' activity users. One family of such data analysis is that of mining of log files of online applications that register the actions of online users during long periods of time. A relevant objective in this case is to study the behavior of online users and feedback the design processes of online applications to provide better usability and adaption to users' preferences. The context of this work is that of a virtual campus in which thousands of students and tutors carry out the learning and teaching activity using online applications. The information stored in log files of virtual campuses tend to be large, complex and heterogeneous in nature. Hence, their mining requires both efficient and intelligent processing and analysis of user interaction data during long-term learning activities. In this paper, we present a bi-clustering algorithm for processing large log data sets from the online daily activity of students in a real virtual campus. Our approach is useful to extract relevant knowledge about user activity such as navigation patterns, activities performed as well as to study time parameters related to such activities. The extracted information can be useful not only to students and tutors to stimulate and improve their experience when interacting with the system but also to the designers and developers of the virtual campus in order to better support the online teaching and learning. © 2010 IEEE.

Optimal simulation of a perfect entangler

Physical Review A 2010年第3期81卷 032328-032328页

A 2⊗2 unitary operation is called a perfect entangler if it can generate a maximally entangled state from some unentangled input. We study the following question: How many runs of a given two-qubit entangling unitary operation are required to simulate some perfect entangler with one-qubit unitary operations as free resources? We completely solve this problem by presenting an analytical formula for the optimal number of runs of the entangling operation. Our result reveals an entanglement strength of two-qubit unitary operations.

International Conference on computer engineering and systems

To meet the MPEG requirements for high data throughput essential for the recent multimedia applications, new data memory organizations are required. In this paper, a scalable memory organization is proposed to accelerate access to randomly rectangular blocks of visual data to be processed as fast as possible. In the proposed design, we load the video frame pixels stored in traditionally linearly addressable memory as a scan-line manner into a two-dimensional accessible memory, which is organized from a × b memory modules in order to access the entire pixels of the block simultaneously, in parallel. So it is more efficient for multiple blocks access to use the 2D data storage than using the traditionally linearly addressable memory. A module assignment function and an address assignment function are proposed to access any aligned or non-aligned block from the memory modules. The proposed design is implemented and mapped onto an FPGA as a case study. Synthesis results indicate that a scalable, cost-effective design is implemented. High performance is achieved, as at reasonably small hardware costs, considerable speedups of up to 20 thousand times can be expected for the hardware implementation versus the software implementation of the proposed memory organization.

The paper introduces a confidential region proposed by T. Yamazaki et al., which is equipped with the equivalent dipole source localization software;SinaPointPro (NEC Corporation). This confidence limit is defined on a direction ofthe radius. This method enables to detect the origin ofthe epilepsy. And also the paper treats a series of its applications by the present author. The author and his collaborators have recorded electroencephalograms (EEGs) from subjects viewing four types of Kanji and arrows representing directional meaning. Subjects were asked to read them silently. The equivalent current dipole source localization (ECDL) method has been applied to these event rerated potentials: averaged EEGs. ECDs were localized to the right and left frontal lobes at latency after 500ms in both cases. Polarities of ERPs were also opposite in the case of opposite directions, and the moments oflocalized ECDs at these latencies were opposite. Pathways of ECDs in silent reading are almost the same in cases of Kanji and arrow. In these cases, no ECD was localized to the Wernike's area and the angler gyrus those are related to the auditory language area, however, ECDs were localized to the Broca's area that is said to be the language area for speech. © 2010 TSI Press.

Power dissipation and reliability are two major challenges when designing gates and circuits using nanoscale devices. This paper proposes a novel approach for the design of CMOS logic gates which aims to simultaneously decrease their power consumption and their probabilities of failure. This new sizing method was evaluated on CMOS inverters and NOR-2 gates at three technology nodes: 16nm, 22nm, and 32nm. The new inverters and NOR-2 were compared to the classic gates. The results show that the new gates have significantly lower power and higher reliability when compared to classic CMOS gates. The results also suggest that the advantages of the new design method are enhanced at smaller feature sizes: at 16nm the new gates outperform the classic ones in reliability, power, and PDP. ©2010 IEEE.

This paper presents a search for a new heavy particle produced in association with a top or antitop quark. Two models in which the new heavy particle is a color singlet or a color triplet are considered, decaying, respectively, to t¯q or tq, leading to a resonance within the tt¯+jets signature. The full 2011 ATLAS pp collision data set from the LHC (4.7 fb−1) is used to search for tt¯ events produced in association with jets, in which one of the W bosons from the top quarks decays leptonically and the other decays hadronically. The data are consistent with the Standard Model expectation, and a new particle with mass below 430 Gev for both W′ boson and color triplet models is excluded at 95% confidence level, assuming unit right-handed coupling.
