Multiple distinct peaks of comparable strength in unsteady pressure autospectra often characterize compressible flow-induced cavity oscillations. It is unclear whether these different large-amplitude tones (i.e., Rossiter modes) coexist or are the result a mode-switching phenomenon. The cause additional spectrum, particularly at low frequency, also unknown. This article describes analyses data using time-frequency methods, namely short-time Fourier transform (STFT) and continuous Morlet...

Abstract Natural source zone depletion ( NSZD ) has emerged as a practical alternative for restoration of light non‐aqueous phase liquid (LNAPL) sites that are in the later stages their remediation lifecycle. Due to significant research, conceptual model evolved dramatically recent years, and methanogenesis is now accepted dominant attenuation process (e.g., Lundegard Johnson ; Ng et al. ). Most methane generated within pore space adjacent LNAPL (Ng from where it migrates through unsaturated...

Nowadays, there is an increasing demand in mining interesting patterns from the big data. The process of analyzing such a huge amount data really computationally complex task when using traditional methods. overall purpose this paper twofold. First, presents novel approach to identify consistent and inconsistent association rules sales located distributed environment. Secondly, also overcomes main memory bottleneck computing time overhead single system by applying computations multi node...

The influence of dechlorinating microorganisms on PCE and its reduced end products in the presence a PCE-containing nonaqueous phase liquid (NAPL) was investigated. Experiments were conducted continuous-flow stirred-tank reactors (CFSTRs) containing mixed culture model NAPL consisting tridecane. Comparisons between biotic abiotic CFSTRs demonstrated that dechlorination resulted factor 14 increase removal rates from NAPL. formation daughter trichloroethene cis-dichloroethene observed, not...

Service can be delivered anywhere and anytime in cloud computing using virtualization. The main issue to handle virtualized resources is balance ongoing workloads. migration of virtual machines has two major techniques: (i) reducing dirty pages CPU scheduling (ii) compressing memory pages. available techniques for live are not able predict advance. In the proposed framework, time series based prediction developed historical analysis past data. generated with transferring iteratively. Here,...

The stock market is very volatile and non-stationary generates huge volumes of data in every second. In this article, the existing machine learning algorithms are analyzed for forecasting also a new pattern-finding algorithm trend developed. Three approaches can be used to solve problem: fundamental analysis, technical learning. Experimental analysis done article shows that could useful investors make profitable decisions. order conduct these processes, real-time dataset has been obtained...

Abstract There are several key data gaps in our understanding of Natural Source Zone Depletion (NSZD) processes at sites impacted by light nonaqueous phase liquid (LNAPL), and quantifying NSZD rates can be challenging due to the inherent differences measurement methods. In this study, four different methods (oxygen influx measured Gradient Method, long‐term carbon dioxide efflux with Carbon Traps, instantaneous Dynamic Closed Chambers (DCC LI‐COR), heat flux from biodegradation Thermal...

Abstract Quantifying the overall progress in remediation of contaminated groundwater has been a significant challenge. We utilized GeoTracker database to evaluate from 2001 2011 at over 12,000 sites California with groundwater. This paper presents an analysis analytical results 2.1 million samples representing least $100 laboratory costs. Overall, evaluation monitoring data shows large decrease concentrations gasoline constituents. For benzene, half showed concentration 85% or more. methyl...

Thermal issues have become critical roadblocks for achieving highly reliable three-dimensional (3D) integrated circuits. This paper performs both the evaluation and mitigation of impact leakage power variations on temperature profile 3D Chip-Multiprocessors (CMPs). Furthermore, this provides a learning-based model to predict maximum temperature, based which simple, yet effective tier-stacking algorithm mitigate CMPs is proposed. Results show that (1) proposed prediction achieves more than...

Purpose Cloud computing provides a dynamic, heterogeneous and elastic environment by offering accessible ‘cloud services’ to end-users. The tasks involved in making cloud services available, such as matchmaking, selection composition, are essential closely related each other. Integration of these is critical for optimal composition performance the service platform.
