Fabrication Of Micro-Meltblown Filtration Media Using Parallel Plate Die Design, Mohammad A. Hassan Jan 2016

Fabrication Of Micro-Meltblown Filtration Media Using Parallel Plate Die Design, Mohammad A. Hassan

Mohammad Abouelreesh Hassan

Meltblown fibers are typically produced using a die technology based on the slot concept, an extension of the sheet die technology with a series of holes substituting the center rectangular slot of the sheet die. While this prevalent technology has met with considerable success, an economical, facile design would be desirable. In this study a new parallel plate die concept to fabricate micro-meltblown fibers that offers simplicity, ease of use, and low cost was examined. The new die concept had parallel plates forming channels for polymer melt to flow through with a set of air holes surrounding them. This die …

On Convergence Analysis Of Dual Proximal-Gradient Methods With Approximate Gradient For A Class Of Nonsmooth Convex Minimization Problems, Sanming Liu, Zhijie Wang, Chongyang Liu Jan 2016

On Convergence Analysis Of Dual Proximal-Gradient Methods With Approximate Gradient For A Class Of Nonsmooth Convex Minimization Problems, Sanming Liu, Zhijie Wang, Chongyang Liu

Chongyang Liu

In this paper, we consider the problem of minimizing a nonsmooth convex objective which is the sum of a proper, nonsmooth, closed, strongly convex extend real-valued function with a proper, nonsmooth, closed, convex extend real-valued function.


Design Analysis Of Fixed-Bed Synergic Adsorption Of Heavy Metals And Acid Blue 25 On Activated Carbon, M.T. Hernandez-Eudave, Adrian Bonilla-Petriciolet, M.R. Moreno-Virgen, C.K. Rojas-Mayorga, R. Tovar-Gomez Jan 2016

Design Analysis Of Fixed-Bed Synergic Adsorption Of Heavy Metals And Acid Blue 25 On Activated Carbon, M.T. Hernandez-Eudave, Adrian Bonilla-Petriciolet, M.R. Moreno-Virgen, C.K. Rojas-Mayorga, R. Tovar-Gomez

Adrian Bonilla-Petriciolet

This study reports the multicomponent adsorption of dye AB25, nickel (Ni2+) and zinc (Zn2+) ions on an activated carbon using binary mixtures of metal and dye, and packed bed columns at different operating conditions. Design parameters of packed bed adsorption columns have been calculated using the breakthrough curves and Thomas model, and an analysis has been performed to determine the effect and magnitude of the synergistic adsorption on the design parameters and adsorbent performance. Results showed that there is a strong synergistic adsorption of heavy metals on activated carbon caused by the presence of dye AB25 in binary mixtures. The …


Critical Point Calculations Of Multi-Component Reservoir Fluids Using Nature-Inspired Metaheuristic Algorithms, Moataz N. Shehata, Seif-Eddeen K. Fateen, Adrian Bonilla-Petriciolet Jan 2016

Critical Point Calculations Of Multi-Component Reservoir Fluids Using Nature-Inspired Metaheuristic Algorithms, Moataz N. Shehata, Seif-Eddeen K. Fateen, Adrian Bonilla-Petriciolet

Adrian Bonilla-Petriciolet

This study introduces the application of nature-inspired metaheuristic algorithms for performing critical point calculations in multicomponent reservoir fluids. These algorithms are Monkey - Krill Herd Hybrid (MAKHA), Intelligent Firefly Algorithm (IFA), Covariance Matrix Adaptation Evolution Strategy (CMAES), Artificial Bee Colony (ABC), Cuckoo Search (CS), Bare Bones Particle Swarm Optimization (BBPSO) and Flower Pollination Algorithm (FPA). Capabilities and limitations of these optimizers have been analyzed using black oil, volatile and condensate reservoir fluids with fifty components. Results showed that BBPSO, IFA and FPA outperformed other nature-inspired methods for critical point calculations in tested fluids. In particular, BBPSO offered the best efficiency-reliability …


Nonlinear 3d Finite Element Modeling For Structural Failure Analysis Of Concrete Sleepers/Bearers At An Urban Turnout Diamond, Minh Vu, Sakdirat Kaewunruen, Mario Attard Jan 2016

Nonlinear 3d Finite Element Modeling For Structural Failure Analysis Of Concrete Sleepers/Bearers At An Urban Turnout Diamond, Minh Vu, Sakdirat Kaewunruen, Mario Attard

Sakdirat Kaewunruen

Railway urban turnout is a special track system used to divert a train from a particular direction or a particular track onto other directions or other tracks. It is a structural grillage system that consists of steel rails, points (or called “switches”), crossings, steel plates, rubber pads, insulators, fasteners, screw spikes, beam bearers (either tim- ber, polymer, steel, or concrete), ballast and formation. There are two types of turnouts, a conventional turnout and a tangential turnout. Standard conventional turnouts are designed typically for straight main line track. The combination of switch length, heel angle, and cross rate defines the turnout …
