Quantum teleportation with a complete Bell state measurement

By using the quantum teleportation protocol, Alice can send an unknown quantum state (e.g. the polarization of a single photon) to Bob without ever knowing about it. This paper discusses a quantum teleportation experiment in which nonlinear interactions are used for the Bell state measurement. Since the Bell state measurement is based on nonlinear interactions, all four Bell states can be distinguished. Therefore, teleportation of a polarization state can occur with certainty, in principle. Details of the theory and the experimental set-up are discussed.     

A continuous damage fracture model to predict formability of sheet metal

A continuous damage fracture model, which consists of a fracture criterion and a continuum damage constitutive law was proposed in this paper to calculate formability of sheet metal. In this model, an extension of the McClintock void growth model was selected as the fracture criterion to be incorporated with a coupled damage‐plasticity Gurson‐type constitutive law. Also, by introducing a Lode angle dependent parameter to define the loading asymmetry condition, the shear effect was phenomenologically taken into account. The proposed fracture model was implemented in user defined material subroutines in ABAQUS. The model was calibrated and correlated by the uniaxial tension, shear and notched specimens tests. Application of the fracture criterion for the Limit dome height tests was discussed and the simulation results were compared with the experimental data.     

Changes in Phytase Activity and Phytate During the Germination of Six Canola Cultivars

Six canola cultivars were germinated for 8-days and the levels of phytate and phytase activity monitored. Of these, the cultivar Regent exhibited the lowest level of phytate as well as the highest phytase activity. Germination of Regent for up to 2-days resulted in the reduction of phytate from 1.26% to 0.85% without any deleterious changes in the quality or quantity of the oil, based on the negligible levels of free fatty acids produced.     

Comparative Quality Characteristics of Chymosin Extracts Obtained by Ultrasound Treatment

An ultrasound method was developed for increased efficiency of chymosin extraction. Ultrasound extraction was carried out with a Tekmar sonic disrupter, and control extraction was by shaking. Use of ultrasound resulted in increase in activity and decrease in nitrogen content, thus increasing the specific activity of chymosin extracts. Proteolytic activity of experimental chymosin was higher at 15 and 20°C, but lower at 35 and 40°C than that of controls. Chymosin extracts obtained by ultrasound treatment were darker, less green, less blue, and more turbid than controls. Ultrasound treatment did not affect activation energies for proteolytic activity, total viable cell counts, or storage stability of chymosin extracts.     

Effects of Freeze-Thaw Abuse on the Viscosity and Gel-Forming Properties of Surimi from Two Species

The effects of cyclic freezing and thawing upon the quality of frozen surimi of two species were studied with respect to sol viscosity, sol rigidity changes during thermal processing and structural failure properties of the cooked gel. A torsion test, used to determine the strength of gels subjected to different thermal histories, revealed that increasing the number of freeze-thaw cycles reduced the strength and deformability of both sand trout and Alaska pollack surimis. Continuous monitoring of sol rigidity during thermal processing showed little changes in thermal transition temperatures caused by freeze-thaw abuse for either surimi but shifts occurred in overall rigidity levels. Particularly dramatic changes were induced in the Alaska pollack rigidity thermogram. The rigidity thermograms of sand trout and Alaska pollack were significantly different, as were their responses to freeze-thaw abuse and low temperature (4°C and 40°C) pretreatments.     

Volatile Alkylphenols and Thiophenol in Species-related Characterizing Flavors of Red Meats

Caprine (goat), ovine (sheep), bovine (cow), equine (horse), swine (pig), and cervine (deer) perinephric fats were quantitatively analyzed for volatile alkylphenols, phenol, and thiophenol. Highly characterizing sheepy-muttony aromas in ovine fats were contributed by p-cresol, 2-isopropylphenol, 3,4-dimethylphenol, thymol, carvacrol, 3-isopropylphenol, and 4-isopropylphenol. Alkylphenols did not appear to contribute distinguishing flavors to caprine, cervine, and veal fats. Cresols (o-, m-, p-), especially m-cresol, appeared to contribute to beef flavors. Diisopropylphenols may contribute oily flavors to equine fat. High concentrations of thiophenol potentiated unpleasant mutton aromas in ram fat.     

Effects of Phosphates on Firming Rate of Cooked Rice

The effects of phosphates having different contents of P₂O₅ on the rate of firming of cooked rice during storage at room temperature were investigated. Phosphates showed a definite effect in retarding the rate of firming of cooked rice. The cooked rice containing phosphates having 60 and 67% P₂O₅ contents were firmed slower by 1.4 and 1.6 times, respectively, than control. Phosphates having more than 68% P₂O₅ content showed similar results to that of 67% P₂O₅ phosphate, implying that P₂O₅ content may be an important effective factor in retarding the firming of cooked rice.     

提升小波变换的三种算法性能比较

离散小波变换(DWT)在语音,图像等信号处理中有着广泛的应用,在JPEG2000标准中就推荐采用5/3和9/7小波来分别进行无损和有损图像压缩,取代基于DCT变换的图像压缩,并且还推荐采用提升方法来实现。提出三种基于提升方法的二维离散小波变换的并行算法,并在超常超标量数字指令(VLIW)的数字信号处理器(DSP)上进行了性能方面的比较。这里,我们以在图像压缩中常用的不同分辨率的图像作为实验对象。实验结果表明,此三种算法对图像数据进行小波变换的处理时间有了明显缩短,并且实现在参数空间的不同点上都得到更好的效果。     

A case study of customer satisfaction for information technology solutions

There are numerous information technology solutions including hardware and software. A company that provides the solution should have knowledge of the customer needs in the purpose of sailing strategy or upgrade policy. The needs are also directly connected to the user satisfaction. However, the users have respective points of view in the needs as well as they may not identify the requirements to improve the solution. SERVQUAL can be an appropriate method to define and measure the customer satisfaction for the information technology solutions. As a case study of the customer satisfaction, the modified SERVQUAL items and scoring method are applied to a cyber-infrastructure system named CyberL ab in Korea. The measurement results of user satisfaction for CyberL ab are provided to confirm that our proposed method performs as we intended. From the results, we can score the satisfaction level of users and identify their needs in the various aspects. The total user satisfaction level for CyberL ab is scored by 88.3.
