The hydrological conditions, suspended matter concentrations and vertical particulate matter flux were measured as the River Vistula flood wave (maximum discharge) was flowing into the southern part of the Gulf of Gdańsk on 26 May 2010. Extending offshore for several tens of kilometres, the river plume was well stratified, with the upper layer flowing away from the shore and the near-bottom wat...
modeling and wrench feasible workspace analysis of a spatial cable suspended robots is presented. a six-cable spatial cable robot is used the same as stewart robots. due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. various workspaces are defined and the results of simulation are presented on the basis of various workspaces and applied...
We introduce coplanar stripline circuits to resolve the ultrafast photocurrent dynamics of freely suspended carbon nanotubes (CNTs) in the time domain. By applying an on-chip pump-probe laser spectroscopy, we demonstrate that CNTs, contacted by metal electrodes, exhibit a picosecond photocurrent response. We find a combination of an optically induced ultrafast displacement current, transport of...
The exciton dynamics for an ensemble of individual, suspended (6,5), single-walled carbon nanotubes revealed by single color E(22) resonant pump-probe spectroscopy for a wide range of pump fluences are reported. The optically excited initial exciton population ranges from approximately 5 to 120 excitons per ∼725 nm nanotube. At the higher fluences of this range, the pump-probe signals are no lo...
abstract lateral intake is a hydraulic structure which is used for diversion of some portion of water from a river for the purpose of irrigation, storage and industrial. most of lateral intakes from canal are installed at canal with inclined banks which has not received the attention of the researchers in the past. since the flow discharge and sediment which enters the intake canal depends on t...
[1] Levees are the primary elements of self-formed submarine channels, yet little is know about their morphodynamics. We present field observations of static levee morphology and stratigraphy in addition to laboratory experiments that link levee morphodynamics to turbidity current flow properties. These observations are used to motivate a levee growth model. Using a three-dimensional seismic vo...
The oil production process is the of extracting from reservoir using wells that have been made. In there are three stages, namely primary recovery, secondary recovery and tertiary recovery. At stage two methods, natural energy (natural flow) artificial lift methods (artificial lift). There basic principles lift, gas pumps. principle to inject into bottom well thereby reducing density pressure g...
In recent decades, the Canada Basin of the Arctic Ocean has experienced rapidly decreasing summer sea ice coverage and freshening of surface waters. It is unclear how these changes translate to deeper waters, particularly as our baseline understanding of organic carbon cycling in the deep basin is quite limited. In this study, we describe full-depth profiles of the abundance, distribution and c...
