Opis:
For the evaluation of the patellofemoral pain syndrome (PFPS) the mediolateral distance between the tibial tuberosity and the trochlear groove (TT-TG) is considered as the gold standard. In this work, we propose to replace the measurement of the TT-TG with conventional tomographic or radiological section images by a smartphone-based mobile sonography system. This new system allows to provide not only ultrasound imaging but also a measuring method for determining the TT-TG using a smartphone as a mobile tracking unit. Moreover, the system supports the diagnosis by acquiring an additional parameter: the mediolateral distance between the intercondylar notch and the tibial tuberosity (TT-IN). The distinctive structure of the intercondylar notch simplifies the examination compared to using the trochlear groove alone. A feasibility study conducted for this paper indicates that this second guideline value is an adequate replacement for the conventional measurement of the TT-TG. Especially in case of trochlea dysplasia the detection and definition of the groove may be difficult and the TT-IN value offers a reasonable alternative. Our study shows that the proposed sonography system is able to accurately determine the TT-TG in a population of symptom-free young subjects. These measurements range from 13.1 ± 4.2 mm for male to 14.8 ± 3.4 mm for female subjects. Our findings correspond to the postulated values of the gold standard. We are able to show that the values for the TT-IN are in a comparable range with 14.4 ± 4.1mm for men and 13.6 ± 4.0 mm for women. We are convinced that this study strongly indicates that the TT-IN is a useful value that is easy to measure with a mobile ultrasound-based measurement system and can provide the same level of diagnostic value compared to the gold standard TT-TG. In conclusion, a new guideline value is presented to complement the measurement of the TT-TG when a pathological anatomy prevents the detection of the groove.

Opis:
A novel optical approach to generating a chirped microwave signal by using a nonuniformly spaced finite impulse response filter is proposed and demonstrated. In this scheme, a narrowband Gaussian pulse is used as the original chirped-free signal, which is easy to be acquired. To eliminate the need of a wideband chirped-free signal, a mixer and a radio frequency signal are used to up-convert the spectrum of the original Gaussian signal. Therefore, the required frequency response can be calculated and reconstructed by a finite impulse response filter with nonuniformly spaced taps. Besides, a dual drive Mach–Zehnder modulator is used to realize single sideband modulation of the chirpedfree signal. Thus, the transfer function induced by the fiber dispersion is eliminated and the chirped microwave signal with any central frequency can be generated. In this paper, a design example of a filter with a central frequency of 10GHz is provided, and generation of the target chirped microwave signal is also demonstrated by numerical simulations.

Opis:
The formulas of spherical triangle, which are widely used to solve various navigation problems, are the important basic knowledge of nautical mathematics. Because the sine rules and the cosine rules for the sides are the fundamental formulas to derive the other spherical triangle formulas, they are also called the genetic codes of the spherical triangle formulas. In the teaching process, teachers usually use the geometric method to derive and prove these fundamental formulas. However, the derivation of geometric methods is complicated and difficult to understand. To improve the teaching process, this paper proposes the three-dimensional rotation method, which is based on conversion of two cartesian coordinate frames using the rotation matrices. This method can easily and simultaneously derive the sine rules, the cosine rules for the sides, and the five-part formulas (I), and is also helpful to solve different kinds of spherical navigation problems.

The objective of this study was to investigate the effect of exogenous selenium (Se) supply (0, 2, 4, 8, 16 μM) on the growth, lipid peroxidation and antioxidative enzyme activity of 100 mM NaCl-stressed melon (Cucumis melo L.) seedlings. Salt stress significantly reduced the growth attributes including stem length, stem diameter, dry weight and increased antioxidative enzyme activity [superoxide dismutase (SOD), peroxidase (POD), catalase (CAT)]. Moreover, the plant exhibited a significant increase in electrolyte leakage and malondialdehyde (MDA) content under NaCl stress. Se supplementation not only improved the growth parameters but also successfully ameliorated the adverse effect caused by salt stress in melon seedlings. However, the mitigation of NaCl-stressed seedlings was different depending on the Se concentration. At lower concentrations (2–8 μM), Se improved growth and acted as antioxidant by inhibiting lipid peroxidation and increasing in SOD and POD enzymes activity under salt stress. At higher concentrations (16 μM), Se exerted diminished beneficial effects on growth. Whereas CAT activity was enhanced. The result indicated that Se supplementation had a positive physiological effect on the growth and development of salt-stressed melon seedlings.

Opis:
In Japan, the treatment of waste concrete scraps has been one of the environmental issues. Therefore, new application using pulsed power discharge has been developed as the recycling method of the coarse aggregates from the waste concrete scraps. In the work, the dependences of the quality of the recycled coarse aggregate by the repetitive pulsed discharge treatments on the consumption energy were investigated. As the results, it was clear that the quality of the recycled coarse aggregate could be controlled by the number of discharge treatments. The recycled coarse aggregate, which satisfied class H under the regulations of Japan Industrial Standard (JIS A5005 and JIS A5021), was produced with the smallest consumption energy when the discharged energy from 0.02 μF of capacitor charged up to 400 kV applied to the waste concrete scraps during single discharge treatment.

We study the influence of membrane noise on the fluctuations of membrane voltage in the Hodgkin-Huxley neuronal system for the giant axon of squids. We find that the resting potentials of membrane patches in the absence of any external stimulus, exhibit apparent rhythmic fluctuation behaviors. The intrinsic fluctuation frequencies of membrane voltage, due to channel noise, thermal noise, or both, roughly share the same frequency ranges, despite that the fluctuations arisen from the former noise are overwhelmingly larger in amplitude than that from the latter. We also show that the rhythmic fluctuations can help enhance the encoding of weak signals within the rhythmic frequencies ranges and thus contribute positively to the information processing in the nervous system.

Opis:
To effectively predict traffic fatalities and promote the friendly development of transportation, a prediction model of traffic fatalities is established based on support vector machine (SVM). As the prediction accuracy of SVM largely depends on the selection of parameters, Particle Swarm Optimization (PSO) is introduced to find the optimal parameters. In this paper, small sample and nonlinear data are used to predict fatalities of traffic accident. Traffic accident statistics data of China from 1981 to 2012 are chosen as experimental data. The input variables for predicting accident are highway mileage, vehicle number and population size while the output variables are traffic fatality. To verify the validity of the proposed prediction method, the back-propagation neural network (BPNN) prediction model and SVM prediction model are also used to predict the traffic fatalities. The results show that compared with BPNN prediction model and SVM model, the prediction model of traffic fatalities based on PSO-SVM has higher prediction precision and smaller errors. The model can be more effective to forecast the traffic fatalities. And the method using particle swarm optimization algorithm for parameter optimization of SVM is feasible and effective. In addition, this method avoids overcomes the problem of “over learning” in neural network training progress.

Opis:
This study comparatively presents the static puncture property of different structures of intra-/inter-laminar reinforced hybrid composites via needle punching and thermal bonding techniques. The tensile and bursting properties of two composites with inter-laminar reinforcement by needle-punching and inter-and-intra- laminar reinforcement by both needle punching and using Kevlar fibres were also evaluated comparatively. The significance of process parameters including the low-melting PET fibre content, take-up speed of the punching machine, the plied orientation between the nonwoven and fabric and thermal bonding on the static puncture resistance was firstly investigated to seek out the significant parameters. The effects of significant processing parameters on static puncture and mechanical properties were explored afterwards. The research result shows that the plied orientation, low-melting PET content and thermal bonding affect the static puncture resistance most significantly. The maximum tensile strength and bursting strength occurred when hybrid composites after thermal bonding were composed of parallel-plied nonwovens and 90°-orientated glass fabric, as well as 70 wt% low-melting PET fibres. Recycled Kevlar fibre reinforcement dissipates additional static puncture resistance, and makes the static puncture resistance higher, as well as the tensile and bursting strengths for resultant hybrid fibre composites. Employing recycled Kevlar fibres is economical for the fabrication of hybrid composites. Diversified economical hybrid composites will be applied as a wall interlayer or garment interlining in the future.

Opis:
The scratch on a fused silica surface was treated as a chain of connected damage sites and mitigated one after another using CO2 laser irradiation. The optical microscopy image shows that a scratch with the width of about 30 μm and length of several millimeters can be completely mitigated without the formation of debris and bubbles. The mitigated scratch can survive under raster scan laser irradiation with the fluency increased up to 11.0J/cm2 at 3ns and 351nm. On the contrary, the substrate without CO2 laser mitigation is seriously damaged under this irradiation. The light modulation induced by mitigation is much smaller when the scratch is mitigated before being damaged. The light modulation is about 2 when the distance to the mitigated sample is larger than 20cm. The birefringence induced by residual stress in the mitigated scratch is measured. The retardance of the mitigated scratch before being damaged is not visible. Therefore, residual stress in this mitigated scratch before being damaged should be not a critical potential risk in laser damage.

TiO2  nanotube arrays were fabricated using electrochemical anodization of titanium foils, where different types of electrolytes were tested to determine conceptual choice for nanotubes fabrication. These electrolytes are 1M (NH4)2SO4  containing 0.5% wt NH4F, 1M Na2SO4  containing 0.5% wt NH4F, 1M NaF containing 0.5% wt (NH4)2SO4  and a mixture of water: ethylene glycol 1:9 containing 0.5% wt NH4F. The foils were marked as EG type (Ethylene Glycol), AS type (Ammonium sulfate), SS type (sodium sulfate) and SF type (sodium fluoride). The photocatalytic capabilities and characterization of the fabricated NTAs were analyzed using SEM, XRD, and DRS. The degradation ratio of designated organic pollutants (Rhodamine B) was analyzed. The obtained results have proven that foils fabricated using Ethylene glycol have significant photocatalytic abilities, with a degradation ratio of EG-SS-SF-AS types being 80% to 85%, 70% to 80%, 70% to 75% and 52% to 55%, respectively.

Opis:
A new insensitive energetic material 2’-methyl-3-nitro-2’H-[1,3’-bi(1,2,4-triazole)]-5,5’-diamine (1) was prepared by a three-step synthesis from commercially available chemicals. The energetic title compound was comprehensively characterized by various means, including FT-IR, multinuclear (1H, 13C, 14N) NMR spectroscopy, elemental analysis, HPLC and thermal analysis. The sensitivities of the synthesized material towards various external stimuli (impact, friction) were determined according to the BAM method. The optimized structure and related thermodynamic parameters were obtained at the DFT-B3LYP/6-31+G** theoretical level. The detonation properties of the material were also predicted according to the Kamlet-Jacobs formulae and the Monte-Carlo method. The results show that the density, heat of formation, detonation velocity, detonation pressure, impact sensitivity and purity were 1.83 g/cm3, 369 kJ/mol, 7.52 km/s, 25.4 GPa, 82.3 J and 97.7%, respectively. In addition, the compound was an insensitive high explosive which could meet the requirements of high energetic materials.
