    Production of Liquid Metal Micro-droplets and Electrical Control of their Size and Rate of Formation

    , M.Sc. Thesis Sharif University of Technology Asiabi Mollahaji, Arezoo (Author) ; Kebriaee, Azadeh (Supervisor)
    Abstract
    The use of liquid metal droplets due to their high electrical and thermal conductivity are used in various industries today. One of the methods of producing these micro-droplets is the flow focusing method, which is widely used to produce integrated and monodispersed droplets. Liquid metals have high surface tension and these micro-droplets are formed only if there is sufficient shear force between the liquid metal and a continuous fluid phase. In the past, they used several different methods such as pressure fluctuations and changes in continuous phase flow rate to control the shear force and produced polymer, gas, etc. micro-droplets.In this research, use the electric potential to control... 

    Dynamic Pricing of Seasonal Goods with Cancellation Right in an Advance-Sale System

    , M.Sc. Thesis Sharif University of Technology Asiabi, Afshin (Author) ; Modarres Yazdi, Mohammad (Supervisor)
    Abstract
    In this investigation, two pricing models are extended with continuous and periodic price settings through dynamic programming approach. In this problem, we intend to sell a perishable product in a finite horizon with no salvage value through an advance-sale system. The objective function in these models is maximizing expected value of firms’ revenue by setting optimal prices in pricing periods. Demand is assumed to be stochastic time and price-dependent and also customers might cancel their reservations by paying a penalty before delivery. Structural properties of the optimal policy are investigated for both models and the concavity and inventory monotonicity properties are proved for both....
