Opis:
Criteria for the possible number of exciton surface states in a multilayer molecular slab are elucidated in detail. Namely, we explicitly determine the domains of system parameters where the size dependence plays a role. We further clarify the way a surface state is localized in the slab in both asymmetric and symmetric configurations. Basing on our results which are obtained within the first nearest layer approximation, we also conjecture properties to be expected when further nearest layers are taken into consideration.

Opis:
A detailed stability analysis is performed for a highly excited semiconductor modelled as an exciton-electron-hole-photon system driven externally by optical pumping. Chaotic self-pulsations are shown to occur on both the upper and lower branches of the bistable steady state curve of the system via a sequence of period-doubling oscillation process. Such a route to chaos is well known in laser physics and in other nonlinear systems but not in highly excited semiconductors yet.

Opis:
Bistable output-input light characteristics in the exciton spectral region have been examined in a ring cavity configuration taking ito account the influence of the presence of free carriers in the cavity as well as of the density-dependence of the exciton damping. The resulting modifications could serve as a means to optimize the optical bistable device operation.

Opis:
Assessing the tendency of suspended sediment concentration (SSC) in the river watersheds enables a better understanding of the hydromorphological properties of its basins and the associated processes. In addition, analyzing this trend is essential to address several important issues such as erosion, water pollution, human health risks, etc. Therefore, it is critical to determine a proper method to quantify spatio-temporal variability in SSC. In recent years, remote sensing and GIS technologies are being widely applied to support scientists, researchers, and environmental resource investigators to quickly and synchronously capture information on a large scale. The combination of remote sensing and GIS data will become the reliable and timely updated data source for the managers, researchers on many fields. There are several tools, software, algorithms being used in extracting information from satellites and support for the analysis, image interpretation, data collection. The information from satellite images related to water resources includes vegetational cover, flooding events on a large scale, rain forecast, population distribution, forest fire, landslide movements, sedimentation, etc., and especially information on water quality, sediment concentration. This paper presents the initial result from LANDSAT satellite image interpretation to investigate the amount of sediment carried downstream of the Ba river basin.
