Modeling stock prices in a portfolio using multidimensional geometric brownian motion

open access: yes, 2018
Modeling and forecasting stock prices of public corporates are important studies in financial analysis, due to their stock price characteristics. Stocks investments give a wide variety of risks. Taking a portfolio of several stocks is one way to minimize

Buoyancy‐Driven Micropolar Fluid Flow Transport in Porous Media With Variable Heat Source and Convective Heating

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...

A Fractional Heston-Type Model as a Singular Stochastic Equation Driven by Fractional Brownian Motion

open access: yesFractal and Fractional
This paper introduces the fractional Heston-type (fHt) model as a stochastic system comprising the stock price process modeled by a geometric Brownian motion. In this model, the infinitesimal return volatility is characterized by the square of a singular

A Collaborative Kalman Filter for Time-Evolving Dyadic Processes [PDF]

open access: yes, 2015
We present the collaborative Kalman filter (CKF), a dynamic model for collaborative filtering and related factorization models. Using the matrix factorization approach to collaborative filtering, the CKF accounts for time evolution by modeling each low ...

Impact of Darcy–Forchheimer Inertial Drag and Heat Dissipation on Micropolar Hybrid Nanofluid Flow via Expanding Surface

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...

Geometric RSK and the Toda lattice

open access: yes, 2013
We relate a continuous-time version of the geometric RSK correspondence to the Toda lattice, in a way which can be viewed as a semi-classical limit of a recent result by the author which relates the continuous-time geometric RSK mapping, with Brownian ...

Dissipative Heat Impact on the Non‐Newtonian Walter's B Nanoliquid Over an Elongating Surface Through a Permeable Medium

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The utilisation of viscoelastic Walter's B nanoliquid in engineering and biomedical applications gained substantial attention because of its ability to provide real‐time fluid behaviour, particularly in the heat flow mechanism. In particular, the flow of viscoelastic fluid over an elongating surface is useful in polymer processing and ...

Simulation and hedging oil price with geometric Brownian Motion and single-step binomial price model [PDF]

open access: yes, 2017
This paper[1] uses the Geometric Brownian Motion (GBM) to model the behaviour of crude oil price in a Monte Carlo simulation framework. The performance of the GBM method is compared with the naïve strategy using different forecast evaluation techniques ...

Flow of Elastoviscous Nanofluid Through an Elongating Surface With Dissipative Heat: A Confluent Hypergeometric Solution

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Thermal energy transport likely through polymer extrusion, cooling of metallic plates, and chemical processing equipment relating to the flow of viscoelastic nanofluid has a greater role in engineering because of its elastic characteristics.
