In our work a new type of open sets is introduced and defined as follows: If for each set that is not empty M in 𝑋 , 𝑀 ≠ 𝑋 and 𝑀 ∈ 𝜏 ∝ such that 𝐴 ⊆ int (𝐴 ∪ 𝑀) , then A in (𝑋, 𝜏) is named ℎ ∝ -open set. We also go through the relationship between ℎ ∝ - open sets and a variety of other open set types as h -open sets, open sets, semi-open sets and ∝ -open sets. We proved that each h -open and open set is ℎ ∝ -open and there is no relationship between ∝ -open sets and semi-open sets with ℎ ∝ -open sets. Furthermore, we begin by introducing the concepts of ℎ ∝ -continuous mappings, ℎ ∝ -open mappings, ℎ ∝ -irresolute mappings, and ℎ ∝ -totally continuous mappings, we proved that each h -continuous mapping in any topological space is ℎ ∝ -continuous mapping, each continuous mapping in any topological space is ℎ ∝ -continuous mapping and there is no relationship between ∝ -continuous mappings and semi-continuous mappings with ℎ ∝ -continuous mappings as well as some of its features. Finally, we look at some of the new class's separation axioms.
本文引入了一种新的开放集,定义如下:如果对于𝑋、𝑀≠𝑋、𝑀∈∝中每个不为空的M的集合,使得(𝑋,)中的a≤≤(∩∩𝑀),则将(𝑋,)中的a命名为∝-开放集。我们还讨论了∝-开集与其他各种开集类型如h -开集、开集、半开集和∝-开集之间的关系。证明了各h -开集和各h -开集是∝-开集,∝-开集和半开集与∝-开集没有关系。进而引入了∝-连续映射、∝-开映射、∝-不确定映射和∝-完全连续映射的概念,证明了在任何拓扑空间中的每一个h -连续映射都是∝-连续映射,在任何拓扑空间中的每一个连续映射都是∝-连续映射,并且证明了在∝-连续映射和半连续映射之间不存在任何关系,并具有∝-连续映射的某些特征。最后,我们来看一些新类的分离公理。

The method is based on the oxidation of acetylcysteine with a ferric ion, followed by reacting of produced ferrous ion with 2,2 ׳ -bipyridyl to form a pink complex, which is stable and water-soluble and has the highest absorption at a wavelength of 524 nm. The limits of Beer's law were in the concentration range of (5-180) µg of acetylcysteine in a final volume of 20 milliliters (0.25-9.0 µg.ml -1 ) and the molar absorptivity of 8633.28 L. mol -1 .cm -1 , Sandell's sensitivity index of 0.0189 µg.cm -2 . The relative error of -4.28% – 4.98 % and relative standard deviation of ± 0.56% - ± 3.75% depending on the concentration level. The limit of detection limit(LOD) and limit of quantitation (LOQ) were calculated and equal to 0.01837 and 0.06124 µg/ml respectively, no inference was observed in the common pharmaceutical excipients. The results obtain by proposed method were in good agreement with those obtain from official British pharmacopoeia using t-test (at 95% confidence limit) which indicates that there is no significant differences between them. The method was successfully applied to determine acetylcysteine in its pharmaceutical preparations.

Zinc Oxide (ZnO) is one of the important semiconductor materials which contribute effectively to the development of the semiconductor industry technology. ZnO nanostructures (NSs) were synthesized using thermal chemical vapor deposition (TCVD) technique under atmospheric pressure at different evaporation boat-substrate distances. ZnO NSs were prepared by oxidizing Znic acetate dihydrate powder within quartz tube instead of its outside. The effect of change evaporation boat-substrate distance (2.5, 4.5, 6.5 and 8.5 cm) on the optical and structural properties of ZnO NSs were studied. ZnO NSs were characterized by UV-Visible spectrophotometer, X-ray diffraction (XRD) technique and photoluminescence (PL) spectroscopy to evaluate its optical and structural properties. Optical band gap measurement results exhibited a red-shifted from (3.25 eV) to (3.05 eV), as the separation distance increased from (2.5 cm) to (8.5 cm), respectively. XRD technique confirms that metal oxide was ZnO and having hexagonal structure. The average crystallite size of the samples was decreased from 63.4 to 58.3 nm, with the increase in separation distance from 2.5 to 8.5 cm. Also, the sharpness, strong intensity and narrow width of dominant diffraction peak indicate the high crystallinity of the prepared ZnO NSs. The PL spectra of the ZnO NSs revealed a wide deep-level emission for all the prepared samples. ZnO NSs grown by TCVD technique may provide potential applications in nano-photovoltaics and nano-photodetectors.
氧化锌(ZnO)是一种重要的半导体材料,对半导体工业技术的发展做出了重要贡献。采用热化学气相沉积(TCVD)技术在大气压下,在不同的蒸发舟皿-衬底距离下合成了ZnO纳米结构。通过在石英管内氧化二水醋酸锌粉末而不是在石英管外氧化来制备ZnO NSs。研究了改变蒸发舟皿-衬底距离(2.5、4.5、6.5和8.5cm)对ZnO NSs光学和结构性能的影响。采用紫外可见分光光度计、X射线衍射(XRD)技术和光致发光(PL)光谱对ZnO纳米结构进行了表征,以评价其光学和结构性能。随着分离距离分别从(2.5cm)增加到(8.5cm),光学带隙测量结果显示出从(3.25eV)到(3.05eV的红移。XRD技术证实金属氧化物为ZnO,具有六方结构。样品的平均晶粒尺寸从63.4nm减小到58.3nm,分离距离从2.5cm增加到8.5cm。此外,主衍射峰的尖锐度、强强度和窄宽度表明所制备的ZnO NSs具有高结晶度。ZnO NSs的PL光谱显示,所有制备的样品都有宽的深能级发射。通过TCVD技术生长的ZnO NSs可以在纳米光伏和纳米光电探测器中提供潜在的应用。

The New Approach Optimization Markov Weighted Fuzzy Time Series using Particle Swarm Algorithm 基于粒子群算法的马尔可夫加权模糊时间序列优化新方法

Markov Weighted Fuzzy Time Series is a forecasting method that applies fuzzy logic to form linguistic variables from existing data. The formation of linguistic variables makes it possible for the forecasting process to be more accurate by considering the uncertainty aspect in decision-making. Its formation is started by grouping the data into a certain number of clusters. The next steps are fuzzification, transition matrix formation, and defuzzification for forecasting. In the process of grouping, the existing data will be grouped into several clusters so that it results in the interval length of each cluster. One of the problems of this grouping is the absence of a base standard in the clustering process so it is prone to have a different value in forecasting accuracy. The difference in the number of the class or interval length will result in different accuracy even though the clustering method that is used is the same. In this study, the author proposes the idea of using Particle Swarm Optimization to improve the interval length. The initial interval that is already obtained through the K-means clustering algorithm will be evaluated using the Particle Swarm Optimization method so that it will have a new interval that later will be used in the fuzzification process and forecasting. The accuracy of forecasting can be calculated by using Mean Absolute Percentage Error from Markov Weighted Fuzzy Time Series conventional method and Markov Weighted Fuzzy Time Series method with Particle Swarm Optimization. The result of this study gives an improvement in error value from 8.03% to 5.88%.
马尔可夫加权模糊时间序列是一种应用模糊逻辑从现有数据中形成语言变量的预测方法。语言变量的形成使预测过程有可能通过考虑决策中的不确定性方面而更加准确。它的形成是通过将数据分组为一定数量的集群开始的。接下来的步骤是模糊化、转换矩阵的形成和用于预测的去模糊化。在分组过程中,现有数据将被分组为几个集群,从而得出每个集群的间隔长度。这种分组的问题之一是在聚类过程中缺乏基本标准,因此它在预测准确性方面往往具有不同的值。类的数量或间隔长度的差异将导致不同的准确性,即使所使用的聚类方法是相同的。在这项研究中,作者提出了使用粒子群优化来提高区间长度的想法。通过K-means聚类算法已经获得的初始区间将使用粒子群优化方法进行评估,以便它将有一个新的区间,稍后将用于模糊化过程和预测。预测精度可采用马尔可夫加权模糊时间序列的均值绝对百分比误差和粒子群优化的马尔可夫加权模糊时序方法计算。本研究的结果使误差值从8.03%提高到5.88%。

Smartphones have become widely employed in a range of fields as a result of substantial developments in communication technology, distribution, and the development of numerous types of smart mobile devices. The goal of this research is to secure information sent over mobile phone networks. In this paper, we propose using cryptography to create a more secure application for transmitting confidential information, using encryption to improve security, and depending on the location of the mobile phone user's coordinates, obtained via GPS, to increase security. The XOR process was used between coordinates, the idea was new, the application was implemented, and good results were obtained. The process of converting text into unreadable text is known as ciphering, and in order to achieve it in this paper the Twofish algorithm was used to encrypt confidential information. When sending the coordinates, the RSA algorithm was used to encrypt them as for the Twofish algorithm, the coordinates serve as a key. We conclude that the proposed system used in this study achieved a high level of security.

In this paper, the pulsed ablation laser in liquids (PLAL)method was used to obtain copper nanoparticles from material copper, one of the first signs of nanoparticle production or generation using the pulsed laser is a change in the color of the sample's solution as the concentration of nanoparticles increases. In our study, deionized distilled water with a volume of 5 mL was used to prepare the samples with energy (300, 500) mj. With number of pulsed (50, 100, 150, 200) pulse respectively. We noticed a change in the color of the solution to a dark white color, indicating the presence of silver nanoparticles. In another side study the obsorbancy and transmission by using UV-Visible spectroscopy, the peaks of all samples were at wave length at (250-260) nm. This confirms that nanoparticles have been obtained from silver material. The determined mean energy gab for direct transition allowed of the samples is 2.74 eV.
本文采用液体脉冲烧蚀激光(PLAL)方法从铜材料中获得铜纳米颗粒,使用脉冲激光产生或生成纳米颗粒的第一个迹象是随着纳米颗粒浓度的增加,样品溶液的颜色发生变化。在我们的研究中,用体积为5 mL的去离子蒸馏水制备能量为(300,500)mj的样品。脉冲数分别为50、100、150、200个。我们注意到溶液的颜色变成了深白色,这表明银纳米粒子的存在。另一方面利用紫外可见光谱法研究了样品的吸光度和透射率,所有样品的峰值波长均在(250 ~ 260)nm。这证实了纳米颗粒已经从银材料中获得。测定样品允许直接跃迁的平均能谱为2.74 eV。

Insects have been considered the main source of very useful chemical compounds. Today, the insect ' s innate immunity is a subject of antibiotic alternatives by experimenting with their body extracts. After application of the "Sequential solvent polarity" method. The dry body extract of the Americana cockroach, Periplaneta americana was exhibited had variable growth inhibition between the tasted pathogenic bacteria, the methanol cold extract was more effective than with other (Hexane, Diethyl ether, Ethyl acetate, Methanol) solvents by inhibition zone diameters; (29.0, 22.0,24.0, 22.3) mm for ( Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae ) respectively. In comparison between the antibacterial of the methanol extracts of the cockroach and the paper wasp Polistes watti, extract of the P. americana in more active in the inhibition of all four tested bacteria as follows: ( Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae ) for (7.7, 18.3, 8.7, 6.0) mm respectively. Extract of P. americana have antibacterial activity do to it living in an ecological niche which characterized by organic and bacterial pollution so, the growth of human pathogenic bacteria in more inhibited than the social entomophagous P. watti wasp. The present study had given promise alternative of the personal antibiotics, by as more effective than the standers drugs (Ceftriaxone, Gentamicin) after separation and identification of the active molecules and used as a template for the future manufacturing industry.
昆虫一直被认为是非常有用的化合物的主要来源。如今,昆虫的先天免疫是抗生素替代品的主题,通过实验它们的身体提取物。应用“顺序溶剂极性”方法后。美洲大蠊(Periplaneta Americana)的干体提取物在尝到的致病菌之间表现出不同的生长抑制作用,甲醇冷提取物的抑制区直径比其他溶剂(己烷、乙醚、乙酸乙酯、甲醇)更有效;(金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌、肺炎克雷伯菌)分别为(29.0、22.0,2.40、22.3)mm。通过比较蟑螂甲醇提取物和纸黄蜂Polites watti的抗菌效果,美洲大蠊提取物对所有四种受试细菌的抑制活性更强,分别为:(金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌、肺炎克雷伯菌)(7.7、18.3、8.7、6.0)mm。美洲大蠊提取物对生活在以有机物和细菌污染为特征的生态位中的大蠊具有抗菌活性,因此,人类致病菌的生长受到的抑制比社会性的食虫大蠊更大。本研究在分离和鉴定活性分子后,与标准药物(头孢曲松、庆大霉素)相比更有效,有望替代个人抗生素,并被用作未来制造业的模板。

In this study, three isolates of Ensifer fredii bv. fredii were isolated from root nodules of Vigna unguiculata L. (Cowpea) which collected from different cultural areas in Nineveh Governorate/Iraq. The rhizobial colonies were purified and their agronomic and biochemical characteristics were studied. Microscopic examination results showed rod negative Gram stain bacteria, whereas the three isolates showed ability to grow on rhizobial minimal medium (RMM), motility on TY semi-solid medium, gelatin liquefaction, citrate utilization as a sole carbon source, as well as the isolates showed a positive result for Triple Sugar Iron (TSI). Antimicrobial activity study of local rhizobial isolates against fungi showed a clear effect on studied fungi. The filtrate culture of Ensifer fredii bv. fredii ORM1 showed inhibition zone effect with average 12.6, 10.3 and 12.0 mm against Aspergillus niger MR1, Fusarium solani MR2 and Penicillium spp. MR3, respectively, whereas the filtrate culture of Ensifer fredii bv. fredii ORM13 showed inhibition zone effect with average 10.0, 13.3 and 13.0 mm against Aspergillus niger MR1, Fusarium solani MR2 and Penicillium spp. MR3, respectively. A filtrate culture of Ensifer fredii bv. fredii ORM23 showed less effect against each of Aspergillus niger MR1 and Penicillium spp. MR3 which inhibition zone average 8.6 mm, whereas there is no inhibition effect were recorded for culture filtrate against Fusarium solani MR2.
