Wettability alteration has been a sophisticated issue for scientists and reservoir engineers since early 20th century; thus, many investigations have been carried out to determine wettability and enhance it to ideal conditions, which leads to improvement in oil recovery. Dilute surfactant flooding has been approved as one of the noteworthy methods in chemical flooding. Several petroleum reservo...

An algorithm for constrained flooding based on negative selection is proposed due to improve delay of flooding and quality of operation when the network transmit the fault information. According to the network environment different demand between delay of flooding and quality of operation, cost function of flooding delay and operation losing are set, the optimizing objective function synthesize...

BACKGROUND AND AIMS Nicaraguan teosinte (Zea nicaraguensis), a species found in frequently flooded areas, provides useful germplasm for breeding flooding-tolerant maize (Z. mays subsp. mays). The objective of this study was to select flooding-tolerant lines using a library of introgression lines (ILs), each containing a chromosome segment from Z. nicaraguensis in the maize inbred line Mi29. M...

Water flooding microscopic seepage experiment is an effective method to study the microvadose mechanisms as well as the distributions of remaining oil. Throughout the experiment the quantitative description of the porous medium fluid flow parameters such as porosity, oil saturation and so forth is crucial. A quantitative analysis method is proposed via image processing, including image preproce...

Geared toward the problems of predicting unsteadily changing single oil well production in water flooding reservoir, a machine learning model based on CNN (convolutional neural network) and LSTM (long short-term memory) is established which realizes precise predictions monthly single-well production. This study considering more than 60 dynamic static factors that affect changes production, intr...

On 10 May 2016, Guangdong Province, China, suffered a heavy rainstorm. This rainstorm flooded the whole city of Guangzhou. More than 100,000 people were affected by the flooding, in which eight people lost their lives. Subway stations, cars, and buses were submerged. In order to analyse the influential factors of this flooding, topographical characteristics were mapped using Digital Elevation M...

Data were provided by the United States Geological Survey on selenium concentrations collected over Benton Lake National Wildlife Refuge near Great Falls, Montana. High selenium concentrations are known to decrease reproduction rates in lake waterfowl (USFWS, 2012, p. 204). Previous work in sediment selenium data included mean concentration estimates and comparisons using several variance estim...

------------------------------------------------------------------ABSTRACT-----------------------------------------------------------------Mobile Adhoc Networks (MANET) are new paradigm of wireless networks providing unrestricted mobility to nodes with no fixed or centralized infrastructure. Each node participating in the network acts as router to route the data from source to destination. This...

Flooding-based DDoS attacks is a very common way to attack a victim machine by directly or indirectly sending a large amount of malicious traffic to it. Stochastic Fairness Queueing (SFQ) is a typical implementation of Fair Queueing. This paper focuses on exploring the feasibility of mitigating flooding-based DDoS attacks by queueing disciplines. A comparative study is made between SFQ and FCFS...
