    , M.Sc. Thesis Sharif University of Technology Chabok, Sheyda (Author) ; Rafiee, Majid (Supervisor)
    Abstract
    Profile Monitoring is a new research topics in the field of statistical process control. In many applications of statistical quality control, sometimes quality of a process or product described by a relationship between a response variable and one or more independent variables.The researchers call this relationship profile. The study seeks to demonstrate that monitoring profiles In addition, the industry can be effective in medical field and improves control of the patient's condition by a doctor. Profiles are usually modeled with a linear regression equation, non-linear or polynomial. finally, the results of this study, using actual data, models and methods to predict and control... 

    Application of artificial neural networks for estimation of the reaction rate in methanol dehydration

    , Article Industrial and Engineering Chemistry Research ; Volume 49, Issue 10 , April , 2010 , Pages 4620-4626 ; 08885885 (ISSN) Valeh E Sheyda, P ; Yaripour, F ; Moradi, G ; Saber, M ; Sharif University of Technology

    Abstract
    In this paper, the artificial neural network has been applied to estimate the reaction rate of methanol dehydration in dimethyl ether synthesis. The multilayer feed forward neural network with three inputs and one output has been trained with different algorithms and different numbers of neurons in the hidden layer. Two thirds of all training data are used for training of the network and the rest are used for testing of the generalization of the network. The accuracy of the proposed model was found to agree well with the experimental results over a wide range of experimental conditions. The results clearly depict that the neural network is a powerful tool to estimate the reaction rate and... 

    Magnetic resonance tensors in uracil: calculation of 13C, 15N, 17O NMR chemical shifts, 17O and 14N electric field gradients and measurement of 13C and 15N chemical shifts

    Abstract
    The experimental 13C NMR chemical shift components of uracil in the solid state are reported for the first time (to our knowledge), as well as newer data for the 15N nuclei. These experimental values are supported by extensive calculated data of the 13C, 15N and 17O chemical shielding and 17O and 14N electric field gradient (EFG) tensors. In the crystal, uracil forms a number of strong and weak hydrogen bonds, and the effect of these on the 13C and 15N chemical shift tensors is studied. This powerful combination of the structural methods and theoretical calculations gives a very detailed view of the strong and weak hydrogen bond formation by this molecule. Good calculated results for the... 

    Design for Fabrication of High Frequency Ultrasound Medical Probes

    , M.Sc. Thesis Sharif University of Technology Babazadeh Khameneh, Ali (Author) ; Nejat Pishkenari, Hossein (Supervisor) ; Chabok, Hamid Reza (Co-Supervisor)
    Abstract
    Imaging using ultrasonic waves is one of the common non-invasive diagnostic methods which have gained a lot of attention in recent years. The imaging resolution depends mainly on the center frequency of the ultrasonic transducer. High frequency ultrasonic imaging is mainly used in intravascular, skin and eye diseases and also in small animal studies. The main Goal of this thesis is to design two high frequency ultrasound imaging probes (between 10 to 50 MHz) which millimetric dimensions which can be used to image skin, eye or intravascular systems. In this thesis after discussing the science of high frequency ultrasound and reviewing the importance papers and books on the subject, two... 

    Bis-N-Heterocyclic carbene complexes of coinage metals containing four naphthalimide units: a structure-emission properties relationship study

    , Article Inorganic Chemistry ; Volume 60, Issue 17 , 2021 , Pages 12924-12933 ; 00201669 (ISSN) Hendi, Z ; Jamali, S ; Chabok, S. M. J ; Jamjah, A ; Samouei, H ; Jamshidi, Z ; Sharif University of Technology

    Abstract
    Naphthalimide derivatives provide highly versatile self-assembled systems and aggregated forms with fascinating emission properties that make them potential candidates for many applications such as bioimaging and sensing. Although various aggregated species of naphthalimide derivatives have been well documented, little is known about the correlation between their structure and photophysical properties. Here the preparation of a series of tetrameric naphthalimide molecules in which naphthalimide units are linked by bis-N-heterocyclic carbene complexes of coinage metals is described. An in-depth structural investigation into these tetramers has been carried out in solution and the solid state... 

    Metal-Organic cubane cage with trimethylplatinum(Iv) vertices

    Abstract
    Herein we describe the synthesis and characterization of the first platinum(IV) metal-organic cage [(Me3PtIV)8(byp)12](OTf)8 (2), in which the organometallic moieties trimethylplatinum(IV) (PtMe3) occupied the corners of a cubane structure and 4,4′-bipyridine ligands used as linkers. The first-principles density functional theory calculations showed that the highest occupied molecular orbitals were localized on the PtMe3 moieties, while the lowest unoccupied molecular orbitals were distributed on the organic linkers. © 2021 American Chemical Society

    Abstract
    In this study the effects of initial concentration of Fe(II) and Fe(III) ions as well as initial pH on the bioleaching of a low-grade sphalerite ore in a leaching column over a period of 120 days with and without bacteria were investigated. Four different modifications of medium were used as column feed solutions to investigate the effects of initial concentration of Fe(II) and Fe(III) ions on zinc extraction. The experiments were carried out using a bench-scale, column leaching reactor, which was inoculated with mesophilic iron oxidizing bacteria, Acidithiobacillus ferrooxidans, initially isolated from the Sarcheshmeh chalcopyrite concentrate (Kerman, Iran). The effluent solutions were...
