A new class of state-space models, reservoir models, with a fixed state transition structure (the "reservoir") and an adaptable readout from the state space, has recently emerged as a way for time series processing and modeling. Echo state network (ESN) is one of the simplest, yet powerful, reservoir models. ESN models are generally constructed in a randomized manner. In our previous study (Rod...

Sarvak formation, with the middle cretaceous (Cenomanian) age, is one of the stratigraphic units of the Bangestan group in the southern Iran. The carbonate rocks of this formation form the reservoir rock in the study field. Generally, Sarvak formation is subdivided into three members including Mishrif, Khatiyah, and Maddud in the Persian Gulf, and the average thickness of the reservoir unit (i....

Fluoride levels were determined in roots, stalks, and leaves of common underwater reeds (Phragmites australis) harvested in 2001 from a polluted reservoir near Luboń and an unpolluted reservoir near Radzewice, Poland. The mean fluoride concentrations in the roots, stalks and leaves of the polluted reservoir were, respectively, 213, 36.8, 51.1 mg F/kg dry mass. In the unpolluted reservoir they w...

A 43-year old patient presented to the emergency department with stretch, due to impossible deflation of the penile prosthesis, 4 years after successful implant. A CT-scan showed migration of the reservoir to the left rectus abdominis muscle. Refilling of the reservoir was inhibited by muscular compression, causing stretch. Removal and replacement of the reservoir was performed, after which the...

it is well-known that dam-reservoir interaction has significant effects on the response of dams to the earthquakes. this phenomenon should be considered more exactly in the seismic design of dams with a rational and reliable dynamic analysis method. in this research, seismic analysis of the dam-reservoir is studied as a wave propagation problem by using legendre spectral element method (sem). t...

background: oyan reservoir, south-west nigeria was constructed in 1984 to generate electricity but has altered the exist­ing physical, biological and socio-economic environment of the people. this study, carried out between october 2006 and march 2008, aimed at investigating the current status of schistosoma haematobium infection around the reservoir. methods: urine samples from 536 participant...

background: an epidemiological study was carried out on the vector(s) and reservoir(s) of cutaneous leishmaniasis in rural areas of kalaleh district, golestan province during 2006 - 2007. methods: totally 4900 sand flies were collected using sticky papers and were subjected to molecular methods for de­tection of leishmanial parasite. results: phlebotomus papatasi was the common species in outdo...

Abstract Assessments of aquifer storage capacity and security have generally assumed that reservoir engineering would be limited to site selection and placement of the injection wells. In previous work we have shown that it is possible to accelerate the dissolution of CO2 in brines by active reservoir engineering achieved by pumping brines from regions where it is undersaturated into regions oc...

Tremendous quantities of reservoir deposited sediments are required to be dredged regularly to maintain the storage capacity of the reservoir. The reservoir dredged material (RDM) can be utilized as construction material after admixing with additives such as cement and fly ash thereby improving its strength characteristics. This research paper presents results of laboratory investigation carrie...
