Abstract:

Homogenization proposed in [Y.-C Wu and M. Żukowski, Phys. Rev. A 85 (2012) 022119] is a procedure to transform a tight Bell inequality with partial correlations into a full-correlation form that is also tight. In this paper, we check the homogenizations of two families of n-partite Bell inequalities: the Hardy inequality and the tight Bell inequality without quantum violation. For Hardy's inequalities, their homogenizations bear stronger quantum violation for the maximally entangled state; the tight Bell inequalities without quantum violation give the boundary of quantum and supra-quantum, but their homogenizations do not have the similar properties. We find their homogenization are violated by the maximally entangled state. Numerically computation shows the the domains of quantum violation of homogenized Hardy's inequalities for the generalized GHZ states are smaller than those of Hardy's inequalities.

Abstract:

Homogenization is an important analysis approach of composite materials with structural hierarchy and can give the prediction of macroscopic properties of the composites. There are many homogenization theories and methods. The present paper discusses applications of some homogenization approaches including both direct and mathematical homogenizations for the analysis of anisotropic composites with periodic microstructures. The macroscopic properties of the composite are predicted by the direct homogenization and the mathematical homogenisation method. The periodic boundary conditions of a representative volume element are implemented by a transformation method of the degrees of freedom. The numerical results are demonstrated for two model composites. The study shows that these two homogenization methods gave the same results for the macroscopic elastic stiffness of the composites although they are of different mathematical forms and different operation procedures.

Abstract:

The effect of homogenizations on the recrystallization microstructure of as-rolled twin roll cast AA3003 alloy were investigated using optical microscope, scanning electron microscopy and electric resistivity measurement. The results indicate that high temperature homogenization significantly decrease the supersaturation of Mn in the alloy, and both the volume fraction and the diameter of intermetallic particles increase as the homogenization temperatures. The shape of the recrystallized grains changes from pancake-like to equiaxed, as the annealing temperature increases above 520°C.

Abstract:

Abstract In 2016, the Royal Dutch Meteorological Office (KNMI) homogenized the daily temperature records for the Netherlands from 1901 to 1950 to allow a realistic comparison of the temperatures from 1901 to the present. The homogenizations for the main station De Bilt were carried out using a Percentile Matching Method (PMM) with one reference station and a 56-month reference period. In this study, it is shown that the corrections in the number of tropical days (maximum temperature ≥ 30 °C) depend strongly on the choice of the reference station and the length of the reference period. A total of 116 different variants of the homogenization of De Bilt were carried out, using all combinations of five reference stations, five reference periods, two ways to calculate percentiles, and two ways to smooth the data. The parameters used for the KNMI’s current homogenization of De Bilt result in a very sharp decrease of tropical days, which is not replicated by the majority of the 116 variants. Moreover, after homogenization, De Bilt appears to be an outlier compared to the other meteorological stations. Therefore, the current homogenized estimates of tropical days for De Bilt should be treated with considerable caution.

Abstract:

Long time series of observed climate data are often affected by changes in the technical conditions of the observations, which cause non-climatic biases, so-called inhomogeneities. Such inhomogeneities can be removed, at least partly, by the spatial comparison and statistical analysis of the data, and by the use of documented information about the historical changes in technical conditions, so-called metadata. Large datasets need the use of automatic or semiautomatic homogenization methods, but the effective use of non-quantitative metadata information within automatic procedures is not straightforward. The traditional approach suggests that a piece of metadata can be considered in statistical homogenizations only when the statistical analysis indicates a higher than threshold probability of inhomogeneity occurrence at or around the date of the metadata information. In this study, a new approach is presented, which suggests that the final inhomogeneity corrections should be done by the ANOVA correction model, and all the metadata dates likely indicating inhomogeneities according to the content of the metadata should be included in that correction step. A large synthetic temperature benchmark dataset has been created and used to test the performance of the ACMANT homogenization method both with traditional metadata use and with the suggested new method. The results show that while the traditional metadata use provides only 1–4% error reduction in comparison with the residual errors obtained by the homogenization without metadata, this ratio reaches 8–15% in the new, permissive use of metadata. The usefulness of metadata depends on the test dataset properties and homogenization method, these aspects are examined and discussed.

Abstract:

The microstructure evolution and composition distribution of the cast Al-3.5Cu-1.5Li-0.11Zr alloy during single-step and double-step homogenization were studied with the help of the optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and transmission electron microscopy (TEM) methods. The results show that severe dendrite segregation exists in the experimental alloy. Six different homogenization treatments, conventional one-stage homogenization and double-stage homogenization are carried out, and the best homogenization treatment of the experimental alloys was achieved. Moreover, the precipitation of Al3Zr particles was significantly different after two kinds of homogenization in the experimental alloy. Compared with the single-stage homogenization, a finer particle size and distribution more diffuse of Al3Zr particles can be obtained in the double-stage homogenization treatment.

Abstract:

Aluminum based alloys of the 5xxx series are identified by a high magnesium content (4÷4.9%) which through its compounds can induce special properties of mechanical strength and resistance to various forms of corrosion. The use of 5083 aluminum alloy is especially intended for pressure vessels, products that work in special conditions of temperature and environment with increased aggressiveness, which requires the request in specifications of special properties, especially in the test of resilience. This paper aims to define the best combination of heat treatments, either homogenization or homogenization and artificial aging, in order to obtain the best mechanical and structural characteristics. Two homogenizations were carried out on the cast products (at 350°C and 450° C, respectively), each followed by artificial aging (180°C or 140°C), with different maintenance times, respectively 1h, 12h and 24h). Finally, structural correlations could be made between the values of mechanical properties (yield strength, hardness, tensile strength, elongation, microhardness and resilience) and the grain size corresponding to each structural condition.

Abstract:

Homogenization of the time series of observed climatic data aims to remove non-climatic biases caused by technical changes during the history of the climate observations. The spatial redundancy of climate information helps to recognize station-specific inhomogeneities with statistical methods, but the correct detection and removal of inhomogeneity biases is generally not easy for the combined effects of individual inhomogeneities. In a homogenization procedure, several time series of a given climatic variable observed in one climatic region are usually homogenized together via a large number of spatial comparisons between them. Such procedures are called relative homogenization. A relative homogenization procedure may include one or more homogenization cycles where a cycle includes the steps of time series comparison, inhomogeneity detection and corrections for inhomogeneities, and they may include other steps like the filtering of outlier values or spatial interpolations for infilling data gaps. Relative homogenization methods differ according to the number and content of the individual homogenization cycles, the procedure for the time series comparisons, the statistical inhomogeneity detection method, the way of the inhomogeneity bias removal, among other specifics. Efficient homogenization needs the use of tested statistical methods to be included in partly or fully automated homogenization procedures. Due to the large number and high variety of homogenization experiments fulfilled in the Spanish MULTITEST project (2015–2017), its method comparison test results are still the most informative about the efficiencies of homogenization methods in use. This study presents a brief review of the advances in relative homogenization, recalls some key results of the MULTITEST project, and analyzes some theoretical aspects of successful homogenization.

Noticing the fact that the classic homogenization theory presented by Oleinik has a high demand for the smoothness of the homogenization solution u 0 , we present a new estimate for the homogenization method under the weaker smoothness that homogenization solution u 0 satisfies than the classical homogenization theory needs.

Abstract:

Aluminum alloy A357 can be heat treated in order to obtain optimum mechanical properties. Moreover, SDAS (Second dendrite arm spacing) is an important structure feature in cast aluminum alloys. The effects of SDAS on the homogenization of Al-Si-Mg alloy are investigated through measurement of SDAS and hardness analysis. The results show that the homogenization time increases as the value of SDAS increases and the homogenization temperature decreases in the homogenization process. The homogenization kinetics equation is: . In addition, the hardness after homogenization treatment at 540°C for 6 hours is advanced with the reduction of SDAS.

Abstract:

A series of Al-6.3Zn-2.3Mg-2.3Cu-0.15Zr alloys with different reduce of Zn, Mg, Cu and Zr were prepared by ingot-metallurgy processing. Effects of homogenization on the microstructure and properties of Al-Zn-Mg-Cu-Zr aluminium alloy were respectively studied by means of metallographic microscopy, electrical conductivity test, differential thermal analysis and X-ray diffraction phase analysis. The results indicated that the overheating temperature of these alloys is between 473°C and 477°C, and there was little difference to the overheating temperature of 7050 alloy. During homogenization process, using three kinds of developed heat treatment of homogenization of 7050 alloy, with the rising of homogenization temperature and the complication of the homogenization heat treatment, the electrical conductivity decreased and hardness gradually increased. The three-step homogenization has a better effect than single homogenization, as it can completely eliminate the endothermic peak of non-equilibrium phases. Many MgZn2 phases are present in the ingot with three-step homogenization and slow cooling.

Abstract:

For the periodical composite structural-acoustic system with multi-scale interval uncertainties, a new interval analysis approach is presented in this study. In periodical composites structural-acoustic systems with multi-scale interval parameters, the variation ranges of the sound pressure response can be calculated using the homogenization-based interval finite element method. However, the homogenization-based interval finite element method that is based on Taylor series can only suit periodical composites structural-acoustic problems with small uncertainty degree. To consider larger uncertainty degree, by combining the Chebyshev polynomial series and the homogenization-based finite element, a homogenization-based Chebyshev interval finite element method is presented to predict the sound pressure responses of the structural-acoustic system involving periodical composite and multi-scale interval parameters. Compared with homogenization-based interval finite element method, homogenization-based Chebyshev interval finite element method can obtain higher accurate numerical solutions in the approximate process. Besides, homogenization-based Chebyshev interval finite element method can be implemented without conducting the complex derivation process. Numerical results verify the validity and practicability of the presented homogenization-based Chebyshev interval finite element method for the periodical composite structural-acoustic problem.

Full text

Abstract:

The effects of double-step homogenization processes on the precipitation of Al3Zr dispersoids and the dissolution of the primary phases of 2196 aluminum alloy were studied by optical microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). It was revealed that first-step homogenization facilitates the nucleation of Al3Zr, while second-step homogenization results in the dissolution of the primary phases and the growth of Al3Zr dispersoids. The nanosized θ’ precipitates formed in the first-step homogenization are dissolved after the second-step homogenization. The optimum homogenization process was selected as 400 °C/10 h + 520 °C/24 h, which effectively dissolves the primary phases and promotes the formation of refined distribution of Al3Zr dispersoids. This phenomenon is mainly caused by the highest nucleation rate of the Al3Zr phase at 400 °C. While reducing the heating rate of the homogenization process can increase the number density of the Al3Zr dispersoids and reduce the precipitate free zone (PFZ), it does not alleviate the inhomogeneity of the Al3Zr precipitation. These results are expected to be meaningful for tailoring the industrial homogenization processing of as-cast Al-Cu-Li alloy.

Abstract:

The behavior of sludge solubilization using high-pressure homogenization (HPH) treatment was examined by investigating the sludge solid reduction and organics solubilization. The sludge volatile suspended solids (VSS) decreased from 10.58 to 6.67 g/L for the sludge sample with a total solids content (TS) of 1.49% after HPH treatment at a homogenization pressure of 80 MPa with four homogenization cycles; total suspended solids (TSS) correspondingly decreased from 14.26 to 9.91 g/L. About 86.15% of the TSS reduction was attributed to the VSS reduction. The increase of homogenization pressure from 20 to 80 MPa or homogenization cycle number from 1 to 4 was favorable to the sludge organics solubilization, and the protein and polysaccharide solubilization linearly increased with the soluble chemical oxygen demand (SCOD) solubilization. More proteins were solubilized than polysaccharides. The linear relationship between SCOD solubilization and VSS reduction had no significant change under different homogenization pressures, homogenization cycles and sludge solid contents. The SCOD of 1.65 g/L was solubilized for the VSS reduction of 1.00 g/L for the three experimental sludge samples with a TS of 1.00, 1.49 and 2.48% under all HPH operating conditions. The energy efficiency results showed that the HPH treatment at a homogenization pressure of 30 MPa with a single homogenization cycle for the sludge sample with a TS of 2.48% was the most energy efficient.

Abstract:

The changes in milk fat globules and fat globule surface proteins of both low-preheated and high-preheated concentrated milks, which were homogenized at low or high pressure, were examined. The average fat globule size decreased with increasing homogenization pressure. The total surface protein (mg m−2) of concentrated milk increased after homogenization, the extent of the increase being dependent on the temperature and the pressure of homogenization, as well as on the preheat treatment. The concentrates obtained from high-preheated milks had higher surface protein concentration than the concentrates obtained from low-preheated milks after homogenization. Concentrated milks heat treated at 79°C either before or after homogenization had greater amounts of fat globule surface protein than concentrated milks heat treated at 50 or 65°C. This was attributed to the association of whey protein with the native MFGM (milk fat globule membrane) proteins and the adsorbed skim milk proteins. Also, at the same homogenization temperature and pressure, the amount of whey protein on the fat globule surface of the concentrated milk that was heated after homogenization was greater than that of the concentrated milk that was heated before homogenization. The amounts of the major native MFGM proteins did not change during homogenization, indicating that the skim milk proteins did not displace the native MFGM proteins but adsorbed on to the newly formed surface.

Abstract:

Abstract The precipitation of secondary Al3(Sc, Zr) particles in Al-Mg-Zn-Sc-Zr alloy during the two-stage homogenization has been studied by OM, SEM, and TEM. The results indicated that Al3(Sc, Zr) particles grew gradually with the first-stage homogenization temperature ranging from 380°C to 440°C. The first-stage homogenization temperature greatly affected the particle size of Al3(Sc, Zr). The lower the first-stage homogenization temperature was, the smaller the particle size of Al3(Sc, Zr) was. After the same second-stage homogenization treatment, the particles were coarsened, and the size was 15.2 nm, 15.9 nm, and 19.7 nm, respectively. Meanwhile, the Al3(Sc, Zr) particles exhibited a legume-like morphology and maintained a coherent relationship with the Al matrix after different homogenization treatments.

Abstract:

This paper examines the cultural homogenization process in Brunei Darussalam. While the success and outcomes of cultural homogenization, in general, have been thoroughly examined and highlighted, recent research trends have also been focusing more on the processes of cultural homogenization on the ground, i.e., the responses and reactions of ordinary people who are, supposedly, at the receiving end of the homogenization process. In the case of Brunei Darussalam (hereinafter Brunei), cultural homogenization strategies were introduced as early as the 1950s, primarily for state-building purposes. Similar to conventional writings, official narratives of Brunei’s homogenization also focus more on the outcomes of the process. Thus, focusing on the Dusun ethnic group as its case study, this article questions the ways the Dusuns view and respond to the homogenization process. This study utilizes the interview data gathered from thirty-four Dusun respondents to examine how they perceive, understand, and react toward the process and related policies. The findings of the study suggest that the Dusuns generally accept the homogenization with a sporadic indication of contestation mainly due to the observable decline of ethnic culture and language. Modernization has also been identified as a notable agent, integrating successfully with the homogenizing process, and driving the latter to the desired outcomes.

Abstract:

In this study, microstructure and corrosion behaviour of homogenized Mg-4Zn-1La magnesium alloy was investigated. Mg-4Zn-1La alloy was produced by low-pressure die casting method. Homogenization treatments were performed at 350 °C and 400 °C for 12, 18, 24 and 48 hours, followed by rapid cooling in water at room temperature. Microstructure characterizations showed that La addition led to a formation of semi-continuous network structure and islands of second phases which identified as T-phase (Mg7Zn3RE). A significant amount of second phase dissolution and an increase in a-Mg grain size with increasing both homogenization time and temperature was observed. Homogenization treatment led to an improvement in corrosion resistance of Mg-4Zn-1La alloy. Homogenization at 400 °C resulted in better corrosion resistance than homogenization at 350 °C for all homogenization duration.

Abstract:

Generally, the high-fidelity finite element models of aero-engines comprise millions of degrees of freedom (DOFs). Although they can provide precise predictions of structural dynamics, the computational cost will be often unaffordable if appropriate dimension reduction techniques are not adopted. The homogenization of the substructure, also termed as the physical replacement, reduces the model scale by simplifying the unnecessary details of the substructure, thus speeding up the dynamic analysis of the whole engine. In this study, we design the physical replacements for the stators of an aero-engine based on the long-wave assumption. These replacements have the same wave features as the stators in long-wave cases while possessing fewer DOFs. The core steps include the analytical description of the stators and the corresponding physical replacement design through two homogenizations. Specifically, we first investigate the wave characteristics of the stators using the wave finite element method and find two dominant waves: flexural and flexural–torsional coupled waves. The first homogenization introduces two analytical Timoshenko beams to describe the two wave motions of the stators. These two analytical beams are subsequently solidified into physical replacements with I, box, and open cross-sections in the second homogenization. The mechanical and geometric parameters are identified through a combination of the static analysis and the genetic algorithm (GA). The search processes are of great efficiency, because all the descriptions are analytical. Results show that the relative errors of the natural frequencies between the pristine stators and the physical replacements associated with the nodal diameters 6–15 are less than 5%.

Abstract:

The present study was conducted to check the feasibility of partial homogenization of market milk used for the preparation of tea (commonly known as ‘chai’ in India) and thereby estimate the energy-saving potential of the process. In the case of partial homogenization of milk, cream with different fat content (15%, 20%, and 25%) was homogenized at three first-stage pressures viz., 1000 psi, 1200 psi, and 1500 psi while keeping the second-stage pressure constant at 500 psi. The homogenization of milk was conducted at 65°C and 70°Ctemperatures. The homogenized cream was used to preparestandardized milk having 4.5% fat and 8.5% solids-not-fat. The temperature and pressure for homogenization were optimizedbased on the desirable least creaming index of samples of standardized milk at 48 h of refrigerated storage (4±2°C). In the case of conventional homogenization of milk, milk was first standardized to 4.5% fat and 8.5% solids-not-fat and then homogenized at 2000 psi and 500 psi for the first and second stages respectively. Tea was prepared from milk obtained from both the homogenization processes and they were subjected to sensory evaluation. The energy consumption in both cases was measured from the energy meter installed at the homogenizer motor. The study revealed that, without affecting the quality of homogenized milk, about 68% of energy could be saved in partial homogenization of milk as compared to conventional homogenization of milk

Abstract:

Background. Turbidity is an important quality parameter of fruit juices. Sedimentation of pulp particles suspended in juice may result in a negative assessment of the product's quality by consumers. Therefore, turbidity stabilization is a challenge for juice producers. In this study, two types of homogenization were used to constrain juice sedimentation. Cloudy juice made of the "Grandarosa" cv. strawberries was used for the research. High-pressure homogenization was carried out with an Atomo 3.0 homogenizer at a pressure of 200 and 600 bar. Ultrasonic homogenization was carried out with a Sonics VCX 750 sonicator using 750W power for 2 and 8 minutes. The juice samples were analyzed for particle size distribution, viscosity, turbidity, total anthocyanin content, phenolic compounds and ascorbic acid content. Results and conclusions. In the case of ultrasonic homogenization, approximately 70 % of the particles present in the juice had a diameter below 25 µm, while in non-homogenized juice, the fraction of particles with a diameter below 25 µm was only 25 %. High-pressure homogenization, regardless of the pressure used, had a higher efficiency in the fragmentation of turbidity particles than ultrasonic homogenization (approximately 90% of the particles below 25 µm in size). Homogenization at a pressure of 200 bar resulted in the highest increase in viscosity to 6.5 mPa·s, by 135 % more than the non-homogenized juice. The juice homogenized ultrasonically for 8 minutes had the highest turbidity level, with a turbidity of 2110 NTU. The average content of total anthocyanins (6 mg/100 cm3) and L-ascorbic acid (16.8 mg/100 cm3) in the strawberry juice did not differ statistically significantly, regardless of the type of homogenization. High-pressure homogenization and ultrasonic homogenization are highly effective in reducing the size of particles in strawberry juice, however, none of them significantly degrades the anthocyanins and ascorbic acid content.

Abstract:

Aim: The present study investigates the influence of various homogenization techniques, namely high-pressure valve homogenization and microfluidization, and different forms of modified sunflower lecithin, including deoiled (DL) and hydrolyzed (HL) variants, on the development of monolayer and bilayer nanoemulsions of chia oil. Methods: Oil-in-water (O/W) nanoemulsions with 5% chia seed oil were prepared using simple (0.5% DL or HL) or double-layer [0.5% DL or HL and 0.3% chitosan (Ch)] stabilization. This involved a two-step homogenization process, utilizing either microfluidization or high-pressure valve homogenization. Chia oil nanoemulsions were characterized by their zeta potential, particle size, and rheological properties. Besides, their physical stability and omega-3 content during refrigerated storage were evaluated. Results: Overall, the studied modified sunflower lecithin (DL and HL) demonstrated effective capability in stabilizing chia nanoemulsions and facilitating the formation of the double-layered structure following Ch deposition. Concerning the homogenization method, it has been demonstrated that under the same homogenization conditions, microfluidization resulted in significantly smaller droplet sizes and higher apparent viscosities compared to high-pressure valve homogenization. This discrepancy can be attributed to the design of the homogenization chambers, as microfluidization generates a narrow distribution of shear forces, while high-pressure valve homogenization yields a much broader distribution. In contrast to chia monolayer nanoemulsions, the nanoemulsions stabilized by modified sunflower lecithin-Ch demonstrated a noteworthy improvement in their overall stability. This enhancement can be ascribed to their increased apparent viscosity and the highly charged interfaces of the droplets. Furthermore, throughout the entire refrigerated storage period, the omega-3 content in all nanoemulsions remained unchanged. Conclusions: In this study, mono and bilayer chia oil nanoemulsions were successfully obtained using modified sunflower lecithin and high-energy techniques. Microfluidization outperformed high-pressure valve homogenization, resulting in smaller droplets and increased viscosity. These findings are relevant for designing stable

Abstract:

Periodic homogenization result for selfadjoint operators via Bloch wave method was obtained by Conca and Vanninathan in [12]. Even though the spectral tools used in [12] are not available in non‐selfadjoint case, it is possible to recover the complete homogenization result of Murat and Tartar in the periodic case through the Bloch wave method. A dominant Bloch mode is introduced and plays the key role in the homogenization process. It is also established that the remainder does not contribute in the homogenization process. This requires separation of scales between the dominant Bloch mode and the rest. This separation is proved via a Poincaré‐type inequality. Further, the proof of homogenization theorem of [12] is simplified.
