the search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولA PbS nanocrystal-C60 photovoltaic device for infrared light harvesting
PbS nanocrystal nc-PbS -C60 photovoltaic devices are demonstrated, in which nc-PbS function as electron donors, showing infrared photosensitivity up to 1600 nm. Annealing nc-PbS is proved to remove capping oleic acid ligands, studied using x-ray photoelectron spectroscopy, significantly improving the short circuit current, open circuit voltage, and fill factor. The device performance is rationa...
متن کاملPbS Colloidal Quantum Dot Photodetectors operating in the near infrared
Colloidal quantum dots have recently attracted lot of interest in the fabrication of optoelectronic devices due to their unique optical properties and their simple and low cost fabrication. PbS nanocrystals emerged as the most advanced colloidal material for near infrared photodetectors. In this work we report on the fabrication and characterization of PbS colloidal quantum dot photoconductors....
متن کاملCCD camera full range pH sensor array.
Changes in colors of an array of optical sensors that responds in full pH range were recorded using a CCD camera. The data of the camera were transferred to the computer through a capture card. Simple software was written to read the specific color of each sensor. In order to associate sensor array responses with pH values, a number of different mathematics and chemometrics methods were investi...
متن کاملGeoreferencing of Ccd Linear Array Sensors Imagery
This paper describes a general sensor model for the georeferencing of imagery from CCD linear array sensors with along-track stereo viewing, carried on airplane or satellite. The model combines the standard photogrammetric triangulation with a sensor external orientation modeling. The sensor attitude and position, which are different for each image-line, are modeled with time-dependent piecewis...
