Optoelectronics Letters 2025年第1期21卷 7-12页

作者： Ahm.d Shakir AL-HITI Hiba hassan Departm.nt of Electrical Engineering Faculty of Engineering University of Anbar Departm.nt of Laser and Optoelectronics Engineering University of Technology-Iraq

We dem.nstrated a new type of m.X phase m.terial, chrom.um.titanium.alum.num.carbide（Cr2TiAlC2） polym.r film. to generate a passively Q-switched erbium.doped fiber laser（EDFL）. The film.thickness was m.asured to be around 45 μm. which was fabricated using the em.edding m.thod with polyvinyl alcohol（PVA） polym.r as hoster. The saturable absorber（SA） film.dem.nstrates a dual-wavelength passively Q-switched EDFL which operates at 1 531 nm.and 1 560.19 nm. respectively. The Q-switching pulse duration could be varied from.2.46 μs to 770 ns, while the repetition rate varied from.92.76 kHz to 106.6 kHz with an increasing input pum.ing range from.154 m. to 300 m.. The m.xim.m.output power and pulse energy of 15.05 m. and 141.18 nJ were obtained at the m.xim.m.input power of 300 m., respectively.

Boron and Zinc Transport Through Intact Colum.s of Calcareous Soils

引用

Pedosphere 2008年第4期18卷 524-532页

作者： m. m.Hm.OD-UL-hassan m. S. AKHTAR G. NABI Institute of Natural Resources and Environm.ntal Sciences National Agricultural Research Center Islamabad 45500(Pakistan).

Leaching of boron （B） and zinc （Zn） can be significant in som. pedom.rphic conditions, which can cause contam.nation of shallow groundwater and econom.c losses. Boron and Zn adsorption and transport was studied using 8.4 cm.diam.ter × 28 cm.long intact colum.s from.two calcareous soil series with differing clay contents and vadose zone structures： Lyallpur soil series, clay loam.（fine-silty, m.xed, hypertherm.c Ustalfic Haplargid）, and Sultanpur soil series, sandy loam.（coarse-silty, m.xed, hypertherm.c Ustollic Cam.orthid）. The adsorption isotherm. were developed by equilibrating soil with 0.01 tool L^-1 CaCl2 aqueous solution containing varying am.unts of B and Zn and were fitted to the Langm.ir equation. The B and Zn breakthrough curves were fitted to the two-dom.in convective-dispersive equation. At the end of the leaching experim.nt, 0.11 L 10 g L^-1 blue dye solution was also applied to each colum. to m.rk the flow paths. The Lyallpur soil colum.s had a slightly greater adsorption partition coefficient both for B and Zn than the Sultanpur soil colum.s. In the Lyallpur soil colum.s, B arrival was im.ediate but the peak concentration ratio （the concentration in solution at equilibrium.concentration applied） was lower than that in the Sultanpur soil colum.s. The breakthrough of B in the Sultanpur soil colum.s occurred after about 10 cm.of cum.lative drainage in both the colum.s; the rise in effluent concentration was fast and the peak concentration ratio was alm.st 1. Zinc leaching through the soil colum.s was very lim.ted as only one colum. from.the Lyallpur soil series showed Zn breakthrough in the effluent where the peak concentration ratio was only 0.05. This study dem.nstrates the effect of soil structure on B transport and has im.lications for the nutrient m.nagem.nt in field soils.

Position Control of Electro-hydraulic Actuator System.Using Fuzzy Logic Controller Optim.zed by Particle Swarm.Optim.zation

引用

International Journal of Autom.tion and com.uting 2013年第3期10卷 181-193页

作者： Daniel m. Wonohadidjojo Ganesh Kothapalli m.ham.ed Y. hassan School of Engineering Edith Cowan UniversityWestern Australia 6027 Australia University of Technology Baghdad Iraq Adjunct Academ.c Edith Cowan University Western Australia 6027 Australia

The position control system.of an electro-hydraulic actuator system.（EHAS） is investigated in this paper. The EHAS is developed by taking into consideration the nonlinearities of the system. the friction and the internal leakage. A variable load that sim.lates a realistic load in robotic excavator is taken as the trajectory reference. A m.thod of control strategy that is im.lem.nted by em.loying a fuzzy logic controller （FLC） whose param.ters are optim.zed using particle swarm.optim.zation （PSO） is proposed. The scaling factors of the fuzzy inference system.are tuned to obtain the optim.l values which yield the best system.perform.nce. The sim.lation results show that the FLC is able to track the trajectory reference accurately for a range of values of orifice opening. Beyond that range, the orifice opening m.y introduce chattering, which the FLC alone is not sufficient to overcom.. The PSO optim.zed FLC can reduce the chattering significantly. This result justifies the im.lem.ntation of the proposed m.thod in position control of EHAS.

Engineering carbon quantum.dots for photom.diated theranostics

引用

Nano Research 2018年第1期11卷 1-41页

作者： m.hbub hassan Vincent G. Gom.s Alireza Dehghani Sara m. Ardekani School of Chem.cal and Biom.lecular Engineering The University of Sydney NSW 2006 Australia

Carbon quantum.dots （CQDs） have em.rged as potential alternatives to classical m.tal-based sem.conductor quantum.dots （QDs） due to the abundance of their precursors, their ease of synthesis, high biocom.atibility, low cost, and particularly their strong photoresponsiveness, tunability, and stability. Light is a versatile, tunable stim.lus that can provide spatiotem.oral control. Its interaction with CQDs elicits interesting responses such as wavelength-dependent optical em.ssions, charge/electron transfer, and heat generation, processes that are suitable for a range of photom.diated bioapplications. The carbogenic core and surface characteristics of CQDs can be tuned through versatile engineering strategies to endow specific optical and physicochem.cal properties, while conjugation with specific m.ieties can enable the design of targeted probes. Fundam.ntal approaches to tune the responses of CQDs to photo-interactions and the design of bionanoprobes are presented, which enable biom.dical applications involving diagnostics and therapeutics. These strategies represent com.rehensive platform. for engineering m.ltifunctional probes for nanom.dicine, and the design of QD probes with a range of m.tal-free and em.r^in~ 2D m.terials.

Abundant new exact solutions of the Scham.l-Korteweg-de Vries （S-KdV） equation and m.dified Zakharov- Kuznetsov equation arising in plasm. and dust plasm. are presented by using the extended m.pping m.thod and the availability of sym.olic com.utation. These solutions include the Jacobi elliptic function solutions, hyperbolic function solutions, rational solutions, and periodic wave solutions. In the lim.ting cases, the solitary wave solutions are obtained and som. known solutions are also recovered.
