While most modern web browsers offer history functionality, few people use it to revisit previously viewed pages. In this paper, we present the design and evaluation of Contextual Web History (CWH), a novel browser implementation which improves visibility feature helps find visited We results formative user study understand what factors helped in finding past From this, developed CWH be more visible users, supported search, browsing, thumbnails, metadata. Combined, these relatively simple...

As an effective security protection technology, intrusion detection technology has been widely used in traditional wireless sensor network environments. With the rapid development of and applications, data traffic also grows rapidly, various kinds viruses attacks appear. Based on temporal correlation characteristics dataset, we propose a multicorrelation‐based model for long‐ short‐term memory networks. The selects optimal feature subset through information gain selection module, converts...

A graph [Formula: see text] is text]-choosable if it has an text]-coloring whenever a list assignment such that for all text]. We provide two sufficient conditions 3-choosability of plane graphs. Every with without cycles length from 4 to 6 and special 7-cycles 3-choosable. 5 adjacent 6-cycles also

In this paper, a two-staged decoding strategy which can be used for the Weighted Bit Flipping (WBF) based algorithm LDPC codes is presented. At two stages, parallel WBF and bit-flipping (BF) algorithms are adopted separately. Correspondingly, by study of iterative process PWBF algorithm, simple function introduced to dynamically implement switch stages. The proposed noticeably lower error floor with modest increase in computation complexity hardware cost. validation verified simulation.

In this paper, we propose an UltraFlow access network enabled by a remotely powered and controlled quasi-passive reconfigurable (QPAR) node. Residing at the remote node (RN), QPAR can dynamically split route optical channels to any users attached its outputs, thereby improving bandwidth efficiency ensuring harmonic coexistence of different services in network. We experimentally demonstrate proposed with 2 × 4 QPAR. The module is local supercapacitor that charged laser power. Remote switching...

<title>Abstract</title> The transformation of acoustic impedance (AI) in different media regulates the transmission and reflection characteristics waves between media, thus enabling many interesting applications. Here we introduce for first time a surface wave (SAW) chip based on AI effect, which utilizes its piezoelectric effect unique interdigital transducer to excite mechanical propagating along crystal, it features high sensitivity surface-loaded such as gases humidity changes due SAW...

In order to solve the problem of "information overflow" in e-learning, an algorithm based on Hebbian learning law is proposed for constructing self-organized communities which can automatically group e-learners according their interests. Unlike filtering methods,this takes into consideration distributed open environment e-learning. This paper designed a peer-to-peer architecture and applied e-learner communities, avoiding difficulty calculating user similarity. Compared with traditional...

This paper describes a domain-specific debugger for one-way constraint solvers. The makes use of several new techniques. First, the displays only portion dataflow graph, called <i>constraint slice</i>, that is directly related to an incorrect variable. technique helps scale system containing thousands constraints. Second, presents visual representation solver's data structures and uses color encodings highlight changes structures. Finally, allows user point variable has unexpected value ask...

The introduction of service-oriented paradigm in grid and corresponding Web services standards has recently demanded the evolution access control solutions to support finegrained authorization requirements dynamic natures derived from environments. In this paper, we present a role-based infrastructure for data sharing management grid. Our advocates flexible resource-centric approach with features distributed systematic delegation administrative authority. seamlessly integrates existing...

A large number of technologies have proved the possibility fast convergence. However most difficult part is not guarantee convergence speed but how to control it properly. In this paper, we proposed a scheme configure parameters routing protocol based on real-time network state evaluation. The goal adjust pace according different importance fault units. We attempt network. All basic functions are closely integrated with state. main contribution our work properly, which also biggest...

Abstract In additive white Gaussian noise (AWGN) channels, construction of polar codes is needed for every operating signal-to-noise ratio (SNR). Recently, the proposal design-SNR reduces computation effort in constructing codes. this paper, we prove that although BER performance not affected, packet-error-rate (PER) degraded compared with point-by-point construction. Therefore, a concatenation scheme proposed to improve PER performance. Results show validity when employing

This paper strengthens the application of adaptive listening technology in S-MAC.When nodes have no data to process, they are dormancy state for most time, while when is coming, become active quickly and participate transmission actively.The which can feel just around will as much possible make continuous within one period.In this way, realize purpose deceasing end delay greatly on basis not increasing additional energy consumption.For applications sensitive system response improved S-MAC...

Passive optical network (PON) is regarded as a promising solution for the broadband bandwidth bottleneck problem. However, due to its passive nature, legacy PON limited by static power distribution, which makes it inefficient. To address this problem, we propose QPAR [4], Quasi-Passive and Reconfigurable node, enables dynamic wavelength assignment so save budget in PON. In paper, study gains that can be achieved employing QPAR, well different factors may facilitate or prevent real...

Google's MapReduce enables program automatic parallelization by partitioning input data and replicating functions, but it does not directly support complex parallel modes like pipeline. However, many are helpful to optimize solution of computing problem. In this paper, we propose EFC (Execution Flow Control), a novel programming model related implementation. It supports an execution-flow control interface which makes the more compatible with different modes. allows user modify execution flow...
