Computing the effective diffusion coefficient of solutes in a multi-salts solutions during forward osmosis (FO) membrane filtration: Experiments and mathematical modelling [PDF]

Journal of Environmental Management, 2018
Diffusion coefficient of solutes through a porous membrane media is different from diffusion coefficient through a free homogenous media. Porosity, tortuosity and the thickness of the membrane significantly affect the diffusion through a specific thickness of a membrane and therefore it is termed as effective diffusion coefficient (Deff) which is lower

A new symmetric modular eleven‐level inverter using single and double source unit for low voltage applications with reduced number of switches

IET Power Electronics, EarlyView., 2023
This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling ...

The Mathematical Foundation of Symbolic Trajectory Evaluation [PDF]

, 1999
In this paper we elucidate the mathematical foundation underlying both the basic and the extended forms of symbolic trajectory evaluation (STE), with emphasis on the latter. The specific technical contributions we make to the theory of STE are threefold. First, we provide a satisfactory answer to the question: what does it mean for a circuit to satisfy

The woman researcher's tale: A review of bibliometric methods and results for studying gender in science

Journal of the Association for Information Science and Technology, EarlyView.
Abstract There has been a notable increase in bibliometric research studying gender in academia. This narrative review aims to organize and synthesize this extensive body of work to uncover new insights into gender disparities in science. We begin by analyzing key methodological elements, including gender assignment techniques, units of analysis, and ...

Corn cob pyrolysis: A systematic literature review of methods and applications

The Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Risk‐Based Expansion Planning of Regional Energy Networks

Energy Science &Engineering, EarlyView.
A risk‐based expansion planning model is proposed for RENs considering operation and investment costs. PVs and WTs power generation, demand response (DR), and failures of tie switches between RENs and distribution networks are defined as RENs operation uncertainties.

Nonfragile Sliding Mode Control of Fractional‐Order Complex Networked Systems via Combination Event‐Triggered Approach

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This work addresses the problem of developing a nonfragile sliding mode observer for fractional‐order complex networked systems (FO‐CNS) under stochastic network attacks. The proposed approach employs a combination of event‐triggered techniques. First, a nonfragile fractional‐order state observer is developed, enabling the design of a suitable
