The Impacts of Autonomous Vehicles on Parking Demand in Urban Areas
, M.Sc. Thesis Sharif University of Technology ; Shafahi, Yousef (Supervisor)
Abstract
Autonomous vehicles will have a major impact on parking demands in urban areas in the future. Compared to conventional vehicles that should park near the destination of the passengers, autonomous vehicles can drop off the travelers at their destinations and then drive to the parking spaces by themselves. However, choosing a parking space in a far zone from the destination could lead to more travel demand in the network. We investigate traffic network equilibrium for traveling and parking with autonomous vehicles under a fully automated traffic environment. We introduce a Bi-level model, considering parking choices in the upper level and route choices in the lower level. The upper-level...
Deriving a Model for Determining the Relative Utility of Residential Apartments for Private Buyers
, M.Sc. Thesis Sharif University of Technology ; Isaei, Mohammad Taghi (Supervisor)
Abstract
In this research, the aim is to find the factors that can influence on the utility perception of both private buyers and experts. What's more, the share of each factor on the overall utility is derived by the use of AHP technique. The next step is to derive a model that contain all the factors seen by private and inexpert buyers., and their relative weight. At the next step, the aime is to complete the model by adding the factors not seen by all private buyers, but advised by residential apartment experts and their relative weight. The model should be able to rank different residential apartments, when the value of each factor is given for each ot the apartments.
Building the external knowledge map for iranian manufacturing SMEs
, Article Proceedings of the European Conference on Knowledge Management, ECKM, 4 September 2008 through 5 September 2008, Southampton ; 2008 , Pages 565-574 ; 20488963 (ISSN); 9781905305537 (ISBN) ; Ashoori, M. T ; Behdad, K ; Sharif University of Technology

Abstract
It is widely recognized that knowledge is an essential strategic resource for a firm to achieve sustainable competitive advantage and Knowledge Management (KM) is a fundamental concept for those interested in the ever changing business world. However, KM has received little attention in Small and Medium sized Enterprises (SMEs). Unique characteristics of SMEs affect their approach in knowledge management, so different KM processes should be applied in these firms. SMEs have very simple structures, so they have less difficulty in managing their internal knowledge than large organizations. But this is not the case for external knowledge management, especially external knowledge acquisition...
Efflux pump inhibitory activity of biologically synthesized silver nanoparticles against multidrug-resistant Acinetobacter baumannii clinical isolates

Abstract
This study was carried out to investigate the possible efflux pump inhibitory activity of biologically synthesized silver nanoparticles (AgNPs) against multidrug-resistant (MDR) Acinetobacter baumannii isolates. In this study, the physicochemical characteristics of synthesized AgNPs were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared spectrophotometer (FTIR) methods. Subsequently, MDR A. baumannii isolates were recovered from clinical samples and the phenotypic cartwheel efflux assay and polymerase chain reaction (PCR) were used to elucidate the possible presence of efflux pump in MDR...
Niosome-encapsulated tobramycin reduced antibiotic resistance and enhanced antibacterial activity against multidrug-resistant clinical strains of Pseudomonas aeruginosa

Abstract
In the current study, niosome-encapsulated tobramycin based on Span 60 and Tween 60 was synthesized and its biological efficacies including anti-bacterial, anti-efflux, and anti-biofilm activities were investigated against multidrug resistant (MDR) clinical strains of Pseudomonas aeruginosa. The niosomal formulations were characterized using scanning electron microscopy, transmission electron microscopy, and dynamic light scattering measurement. The encapsulation efficiency was found to be 69.54% ±; 0.67. The prepared niosomal formulations had a high storage stability to 60 days with small changes in size and drug entrapment, which indicates that it is a suitable candidate for pharmaceutical...
