Opis:
Most primary explosives are non-conductors, easily accumulate charge when contacting with and separating from other materials, and are sensitive to electrostatic discharge (ESD). In order to reduce the number of accidents caused by ESD initiation of primary explosives, studies on their electrostatic hazards are necessary. This work presents comprehensive experimental results of electrostatic discharge sensitivity and chargeability of tris(carbohydrazide)zinc perchlorate (ZnCP) under different conditions. The influences of the testing conditions, of devices, particle size, ambient temperature and relative humidity on the electrostatic discharge sensitivity and chargeability have been investigated in detail, and the quantitative regression equations obtained.

Opis:
In this paper, a novel switching-capacitor DC-DC voltage converter with higher efficiency will be presented. This circuit was designed by modifying the output stage of the conventional static charge-transfer-switch (CTS) charge pump in a cross-coupled configuration. In this design, a control scheme to overcome both the reverse charge sharing and the threshold drops in the CTS pump was also employed. In this study, the capacitances for all the pumping capacitors were selected the same as 0.1 μF. With this design, our circuit can operate with a clock rate up to 1 MHz. The performance of this circuit was first evaluated by simulation by HSPICE with the 0.35-μm technology of TSMC. The results showed that this circuit can pump the low input of 1.5V nearly 5 times at the output. The conversion gain can be around 95%. The performance of the real chip manufactured by TSMC was measured and will be compared with the simulation results.

Opis:
The normal modes cannot be extracted even in the Pekeris waveguide when the source-receiver distance is very close. This paper introduces a normal mode extraction method based on a dedispersion transform (DDT) to solve this problem. The method presented here takes advantage of DDT, which is based on the waveguide invariant such that the dispersion associated with all of the normal modes is removed at the same time. After performing DDT on a signal received in the Pekeris waveguide, the waveform of resulting normal modes is very close to the source signal, each with different position and amplitude. Each normal mode can be extracted by determining its position and amplitude parameters by applying particle swarm optimization (PSO). The waveform of the extracted normal mode is simply the waveform of the source signal; the real waveform of the received normal mode can then be recovered by applying dispersion compensation to the source signal. The method presented needs only one receiver and is verified with experimental data.

Opis:
A new osmylid neuropteran insect Archaeosmylidia fusca gen. et sp. nov. is described from the Middle Jurassic locality of Daohugou (Inner Mongolia, China). Its forewing venation differs from that of other hitherto known osmylids by a set of plesiomorphic features. This genus is considered here as representing a basal group of Osmylidae. The Permian–Triassic family Archeosmylidae comprises the genera Archeosmylus, Babykamenia, and Lithosmylidia. Archaeosmylidia and Archeosmylidae share the few−branched CuP, the absence of zigzag vein pattern, and the scarcity of the crossveins in the radial space.Weestimate that Osmylidae might have originated in the Triassic from some “archeosmylid−like” ancestor.

Opis:
A new tealliocaridid eumalacostracan is described from the Late Carboniferous Tupo Formation (Ningxia, China). Laevitealliocaris xiaheyanensis gen. et sp. nov. is represented by a single specimen, characterised by the possession of a short rostrum without dorsal spine, a short postcervical carina and only one weak branchial carina, both tuberculate, and a short sixth pleonal somite. This is the first unequivocal record of tealliocaridids outside Euramerica, which occurrence along the eastern inner margin of the Palaeotethys suggests that these crustaceans were more widely distributed than previously recognised, very likely extending to the whole intertropical area. The new occurrence demonstrates that tealliocaridids had strong dispersal capacities, interestingly challenging their affinities with peracarids, which today do not have free-living larvae, unlike decapod crustaceans.

Opis:
The core idea of reliability design is to mitigate the product’s failure modes. However, for the cross-links among potential failure modes of a complex product, it is very difficult to establish the mapping relationship between failure modes mitigation and quantitative values of reliability, and the decision of failure modes mitigation have to be performed by virtue of experience, which always increase design period. In order to solve these problems, a novel logic-based approach for failure modes mitigation control and quantitative system reliability analyses is provided. Firstly, a hybrid of active and passive control process of reliability design is proposed. Secondly, a novel concept of failure modes correlation set (FMCS) and a determination approach based on deductive theory are presented. According to the changes in failure modes probabilities of occurrence, the reliability formulas of the components and assemblies are provided to depict the effects of failure mode mitigation on reliability of components and assemblies. And then the FMCS mitigation sequence is decided to determine reliability design activities. Thirdly, a closed control process of FMCS mitigation is provided integrated with logic decision method. By exposing the design of a helicopter fuel system, the present study demonstrates that all approaches are feasible, and the relationship between reliability parameters and qualitative design exists. Hence the failure modes mitigation could be controlled for the achievement of quantitative reliability requirements.
Podstawowym problemem w procesie projektowania niezawodności jest ograniczenie przyczyn uszkodzeń produktu. Jednakże, w przypadku sieci połączeń pomiędzy możliwymi przyczynami uszkodzeń złożonego produktu, trudno jest ustalić mapę zależności pomiędzy ograniczaniem przyczyn uszkodzeń i ilościowymi wartościami niezawodności, a decyzje względem ograniczania przyczyn uszkodzeń muszą bazować na własnym doświadczeniu, co znacznie wydłuża okres projektowania. W celu rozwiązania powyższych problemów, zaproponowano oryginalną, opartą na logice, metodę kontroli ograniczania przyczyn uszkodzeń i ilościowej analizy niezawodności systemu. Na wstępie, zaproponowano mieszany proces aktywnej i pasywnej kontroli niezawodności projektu. Następnie, zaprezentowano oryginalną koncepcję zbioru korelacji przyczyn uszkodzeń (FMCS) i metodę oznaczania opartą o teorię dedukcji. Na podstawie zmian dotyczących prawdopodobieństwa występowania przyczyn uszkodzeń, określono wzory niezawodności części i układów w celu pokazania wpływu ograniczania przyczyn uszkodzeń na niezawodność części i układów. Określono następnie ograniczającą sekwencję FMCS, ażeby ustalić założenia dla projektowania niezawodności. Na koniec zaprezentowano zamknięty proces kontroli ograniczania FMCS w powiązaniu z logiczną metodą podejmowania decyzji. Analizując pod tym kątem projekt systemu paliwowego helikoptera, wykazano w niniejszej pracy przydatność wszystkich powyższych metod, jak również związek pomiędzy parametrami niezawodności a projektowaniem jakościowym. Dlatego też ograniczanie przyczyn uszkodzeń powinno być kontrolowane w celu osiągnięcia wymaganej niezawodności ilościowej.

Opis:
This paper firstly expands an efficient numerical methodology developed from the source panel method to the added mass calculation of long column systems in fluid. Structures submerged in fluid are considered as two-dimensional and are discretized into a number of source panels. The influence coefficient matrices and the potential function are then calculated and the fluid forces are calculated by the unsteady Bernoulli equation. Finally, we utilize this present method to calculate the mass coefficients of some typical problems, which effectively verifies its feasibility and accuracy. This method takes into account both applicability and computational efficiency. On the one hand, in contrast to the analytical method which is only applicable to specific cross-sections, this method is applicable to arbitrary boundaries with C0 continuity in mathematics. On the other hand, this method requires less mesh and computation than commercial software. This paper extends the application of the source panel method which is widely used in aerodynamics to provide a reference for added mass calculation problems in engineering.

Opis:
Distillation processes reveal complicated multivariable nonlinear dynamics for which it is difficult to design a high-performance control system. This paper proposes an adaptive control scheme for a distillation column. The proposed adaptive system consists of a multivariable receding-horizon predictive controller using a transfer function model and a recursive least-squares (RLS) based estimator. Simulations show a consistent closed-loop performance despite the uncertain nonlinear characteristics of the distillation column.

Opis:
FeCrAl is comprised essentially of Fe, Cr, Al and generally considered as metallic substrates for catalyst support because of its advantage in the high-temperature corrosion resistance, high mechanical strength, and ductility. Oxidation film and its adhesion on FeCrAl surface with aluminum are important for catalyst life. Therefore various appropriate surface treatments such as thermal oxidation, Sol, PVD, CVD has studied. In this research, PEO (plasma electrolytic oxidation) process was applied to form the aluminum oxide on FeCrAl surface, and the formed oxide particle according to process conditions such as electric energy and oxidation time were investigated. Microstructure and aluminum oxide particle on FeCrAl surface after PEO process was observed by FE-SEM and EDS with element mapping analysis. The study presents possibility of aluminum oxide formation by electro-chemical coating process without any pretreatment of FeCrAl.

Opis:
Purpose: In this work, a finite element study is proposed to evaluate the effects of the transducer and its coupling layer on the performance of round window (RW) stimulation. Methods: Based on a set of micro-computer tomography images of a healthy adult’s right ear and reverse engineering technique, a coupled finite-element model of the human ear and the transducer was constructed and verified. Then, the effect of the cross-section of the transducer, the elastic modulus of the coupling layer, the mass of the transducer, and the preload of the transducer were studied. Results: The increase of the transducer’s cross-section area deteriorates the RW stimulation, especially at the lower frequencies. This adverse effect of the cross-section area’s increase of the transducer can be reduced by adding a coupling layer between the transducer and the RW. However, the coupling layer’s improvement on the RW stimulation is reduced with the increase of its elastic modulus. Moreover, the mass loading of the transducer decreases the RW stimulation’s performance mainly at higher frequencies and applying a static preload on the transducer enhances its hearing compensating performance at higher frequencies. Conclusions: The influence of the transducer’s mass, the mass of the transducer, the applied static preload and the properties of the coupling layer must be taken into account in the design of the RW stimulation type implantable middle ear hearing device.

Opis:
Due to the characteristics of high gas, high geothermal temperature and high strength development in Huainan mine area, thermal hazard problem has become more and more serious and also affects safety and productivity in coal mine. The CCHP (combined cooling heating and power), as a new mode to control thermal hazard, is put forward after advantages and disadvantages of all kinds of cooling methods are investigated. The CCHP method not only takes full advantage of gas but also reduces the greenhouse gas emission. At the same time, the application of CCHP remits the pressure of the power supply in summer, providing guarantee for safe and high efficiency exploitation.
W związku z wysoką gazonośnością, wysoką temperaturą pierwotną górotworu i wysokimi wartościami zawartości metanu w kopalni Huainan zaobserwowano zagrożenia natury cieplnej, wpływające również na bezpieczeństwo i wydajność produkcji w kopalni. Po zbadaniu wad i zalet różnych metod klimatyzacji podjęto decyzję o wprowadzeniu systemu trójgeneracji jako nowego sposobu kontroli zagrożeń natury cieplnej. Metoda trójgeneracji nie tylko wykorzystuje pełen potencjał ujętego gazu, ale również pozwala obniżyć emisję gazów cieplarnianych. Zastosowanie tego systemu zmniejsza ponadto pobór energii zasilającej w porze letniej, dając gwarancję bezpiecznej i wydajnej eksploatacji kopalni.

Opis:
Fertilizer encapsulation through polymer membranes can reduce fertilizer losses and minimize environmental pollution. In this paper, an emulsion of ethyl cellulose (EC)/vinyl acetate (VAc)/butyl acrylate (BA) was successfully prepared by pre-emulsified semi-continuous seed emulsion polymerization. EC/BA/VAc films showed biodegradability. The influence of the EC content on the properties of EC/BA/VAc films was also investigated by DSC, a water absorbency analysis, etc. Controlled-release urea encapsulated by EC/BA/VAc latex was prepared in a film coating machine and conformed to the standards for slow-release fertilizers of the Committee of European Normalization. The release of urea from controlled-release urea encapsulated by EC/BA/VAc latex containing 0%, 5%, 10%, and 15% EC was 75.1%, 65.8%, 70.1% and 84.1%, respectively, after 42 days, and controlled-release urea encapsulated by EC/BA/VAc latex (5% EC) had the best controlled-release ability. Therefore, controlled-release urea encapsulated by EC/BA/VAc latex has many potential applications in agricultural industry.

Opis:
The behaviors of copper (Cu) precipitation along the radial direction of the 300 mm Czochralski grown silicon wafer have been investigated. It is found that the density of Cu precipitates decreases from the center to edge of the silicon wafer. Moreover, it is revealed that the density of grown-in oxygen precipitates also decreases along the radial direction as mentioned above. Therefore, it is apparent that the Cu precipitate density is positively correlative to the grown-in oxygen precipitate density. This is due to that the grown-in oxygen precipitates can serve as the heterogeneous nucleation centers for Cu precipitation. It is suggested that the Cu decoration in combination with preferential etching can be used to indirectly evaluate the radial distribution of grown-in oxygen precipitates in the silicon wafers.

Defect structure of Czochralski grown silicon (Cz-Si) with nitrogen admixture, c_{N} ≤ 5 × $10^{14} cm^{-3}$ (Cz-Si:N), annealed for up to 10 h at 1270-1400 K under hydrostatic Ar pressure ≤ 1.1 GPa, was investigated by synchrotron diffraction topography (HASYLAB, Germany), X-ray reciprocal space mapping, and infrared spectroscopy. Extended defects were not detected in Cz-Si:N processed at up to 1270 K. Such defects were created, however, in Cz-Si:N pre-annealed at 923 K and next processed at 1270 K or in as-grown Cz-Si:N processed at 1400 K. Investigation of temperature-pressure effects in nitrogen-doped silicon contributes to the understanding of defect formation in Cz-Si:N.
