Opis:
The study site, 2700 m a.s.l., is located in the central Taiwan. A globally rare combination of the mean temperature (ca. 9.5 °C) and total annual precipitation (ca. 4100 mm) makes studies on pedogenic and edaphic processes of the moist soils in this area worthwhile. The study was undertaken to investigate distribution and characteristics of humic substances in this subalpine forest ecosystem. Fulvic acids comprised a higher total organic carbon fraction (1.8 to 25%) than humic acids (1.1 to 13.4%). Fulvic acids were more mobile and migrated downwards to deeper horizons. Comparatively, humic acids were distributed more in the surface horizons. The hu- mification index, based on E4/E6, showed that humification varied in different horizons even in the same profile. The AlogK and RF values indicate that the types of humic acids extracted from Tsuga forest soil are grouped as P or A types, whereas Rp or B types are in Picea forest soil, suggesting a high degree of humification of humic acids in such soils. Features of the absorption spectra were consistent with the classification of humic acids with A logK and RF values. Humification indices and humic acid types in these subalpine soils indicate that they are similar to acidic soils elsewhere with abundant rainfall and cold climate.

Opis:
The exact stability bound of the parasitic parameter for a discrete-time singularly perturbed system is determined by the linear fractional transformation (LFT) framework. Two systematic approaches including time-domain and frequency-domain methods are proposed to solve this problem based on the unified LFT framework. One employs the Kronecker product of LFTs and the guardian map theory. The other is to plot the eigenvalue loci of a real rational function matrix. Two examples are given to show the feasibility of the approaches.

Opis:
In this study, an effective optimization approach was proposed to improve acoustical behaviors of PU foams. The important parameters of PU foams: content of water, silicone oil and catalyst A1 were chosen and their effects on sound absorption coefficient and transmission loss of PU foams were studied by using Taguchi methods. In addition, bamboo chips were incorporated into PU foams as fillers to improve the acoustical properties of PU foams. Four controlled factors: the content of water, silicone oil, catalyst A1 and bamboo chips with three levels for each factor were chosen and Taguchi method based on orthogonal array L9 (34) was employed to conduct the experiments. Based on the results of Taguchi’s orthogonal array L9 (34), signal-to noise (S/N) analysis was used and developed to determine an optimal formulation of PU-bamboo-chips foam composites.

Opis:
In this paper, the robust asymptotic stability problem for a class of nominally stable uncertain singularly perturbed systems with multiple non-commensurate time delays is considered. A delay-dependent criterion is first proposed in this paper to guarantee robust asymptotic stability of the system under consideration. Based on this result, the range of allowable bounds of the perturbation matrices preserving the closed-loop stability can easily be found. Moreower, a simple criterion is also proposed to guarantee asymptotic, stability of the nominal system. Furthermore, a simple estimation of the stability bound epsilon* is proposed such that the nominal system is asymptotically stable for epsilon [belongs to](0,epsilon*). It can be seen that the stability bound proposed in this paper is less conservative than that presented in recent research. Finally, a numerical example is provided to illustrate our main results.

Opis:
The dynamic strength and accumulated plastic strain are two important parameters for evaluating the dynamic response of soil. As a special clay, the remolded red clay is often used as the high speed railway subgrade filling, but studies on its dynamic characteristics are few. For a thorough analysis of the suitability of the remolded red clay as the subgrade filling, a series of long-term cyclic load triaxial test under different load histories are carried out. Considering the influence of compactness, confining pressure, consolidation ratio, vibration frequency and dynamic load to the remolded red clay dynamic property, the tests obtain the development curves of the dynamic strength and accumulated plastic strain under different test conditions. Then, through curve fitting method, two different hyperbolic models respectively for the dynamic strength and accumulated plastic strain are built, which can match the test datum well. By applying the dynamic strength model, the critical dynamic strength of the remolded red clay are gained. Meanwhile, for providing basic datum and reference for relevant projects, all key parameters for the dynamic strength and accumulated plastic strain of the remolded red clay are given in the paper.

Opis:
There are an increasing number of binaural systems embedded with head-related transfer functions (HRTFs), so listeners can experience virtual environments via conventional stereo loudspeakers or head- phones. As HRTFs vary from person to person, it is difficult to select appropriated HRTFs from already existing databases for users. Once the HRTFs in a binaural audio device hardly match the real ones of the users, poor localization happens especially on the cone of confusion. The most accurate way to obtain personalized HRTFs might be doing practical measurements. It is, however, expensive and time consuming. Modifying non-individualized HRTFs may be an effort-saving way, though the modifications are always accompanied by undesired audio distortion. This paper proposes a flexible HRTF adjustment system for users to define their own HRTFs. Also, the system can keep sounds from suffering intolerable distortion based on an objective measurement tool for evaluating the quality of processed audio.

In this paper, the research on discrete descriptor systems is extended to include discrete multiple time-delay descriptor systems. The impulse-free and D-stability problem for a class of discrete descriptor systems with multiple time delays is investigated. A delay-dependent criterion is first derived to guarantee that the system is proper. A delay-dependent stability criterion in terms of spectral radius is then presented to ensure the D-stability of the system. Furthermore, a delay-dependent criterion is proposed to guarantee that the system is nebular, impulse-free, and D-stable. Finally, a numerical example is provided to illustrate our main results.

Opis:
The concept of combining robust fault estimation within a controller system to achieve active Fault Tolerant Control (FTC) has been the subject of considerable interest in the recent literature. The current study is motivated by the need to develop model-based FTC schemes for systems that have no unique equilibria and are therefore difficult to linearise. Linear Parameter Varying (LPV) strategies are well suited to model-based control and fault estimation for such systems. This contribution involves pole-placement within suitable LMI regions, guaranteeing both stability and performance of a multi-fault LPV estimator employed within an FTC structure. The proposed design strategy is illustrated using a nonlinear two-link manipulator system with friction forces acting simultaneously at each joint. The friction forces, regarded as a special case of actuator faults, are estimated and their effect is compensated within a polytope controller system, yielding a robust form of active FTC that is easy to apply to real robot systems.

Opis:
A numerical modeling study is undertaken to understand gas-solid particle flows at the face of a mechanically developing roadway of an underground coal mine which employs a force-exhaust auxiliary ventilation system and uses mist spray for dust suppression. The FLUENT, a commercial computational fluid dynamics (CFD) package is used with Semi Implicit Method for Pressure Linked Equations (SIMPLE) algorithm for simulation. The results of the modeling show that dust control should focus on the middle area of the face. Based on the results, an enclosed dust removal system with ducting was developed. The system was successfully trialed at an underground coal mine with a satisfactory result.

Dla celów symulacji użyto pakietu FLUENT - ogólnodostępnego systemu pomiaru dynamiki płynów w połączeniu z algorytmem SIMPLE. Wyniki modelu pokazują, że odpylanie winno koncentrować się na środkowej powierzchni przodka. Na podstawie uzyskanych wyników opracowano zamknięty system odpylania z kanalizacją. System przetestowano w kopalni z zadowalającym efektem.

Opis:
Achilles tendon rupture is a severe injury with poor curative effect due to its anatomical characteristic and mechanical peculiarity. Internal fixation of limited loop (IFLL) with steel-wire has been applied on patients with tendon rupture to fix the broken ends before physical rehabilitation. The purpose of this study is to investigate the biomechanical property and radiological characteristic of such suture technique for the repairment of tendon rupture. Methods: Tendons of pigs’ hint feet were separated for the biomechanical study. Suture surgery was performed according to the protocol of IFLL. Biomechanical Testing Machine was adopted to conduct the biomechanical tensile load examination. The maximal load, elastic modulus and tendon stiffness of the stitched tendons with or without reinforcement were examined. Results: The maximum tensile load of the stitched tendons using IFLL reached 1/4 of the uninjured tendon’s maximum tensile load, indicating that such suture technique is capable of providing enough tension for the ruptured tendon. Surprisingly, tendons fixed with titanium wire showed the highest load tension, which was comparable to the undamaged tendon. Therefore, we found the biomechanical basis of using IFLL in effectively connecting the rupture ends of tendons. Conclusions: In conclusion, we provide biomechanical evidence for the use of IFLL in treatment of Achilles tendon rupture, by providing enough strength for the ankle function. Such suture technique could help the patients with better rehabilitation and reduced in-hospital stay after Achilles tendon injury.

Nanothermite composites containing metal oxide and metal fuel are attracting attention due to their outstanding combustion characteristics. The morphology of metal oxide is important for the performance of nanothermite composites. In this paper, branch-, plate-, sphere-, and hollow sphere-like CuO nano/microstructures were synthesized via a facile hydrothermal process. The CuO/Al based nanothermites were prepared via ultrasonic mixing of the asobtained CuO products and nano-Al. The combustion behaviour of CuO/Al based nanothermites was analyzed by DSC and laser ignition. This study shows that this nanoscale mixing resulted in a large interfacial contact area and low diffusional resistance between the fuel and the oxidizer, and the reaction reflects large energy and laser ignition sensitivity.

Strategic planning and development is a critical yet often overlooked issue in company's operations. The planning of development as well as addressing the distribution of available resources should be done systematically rather than instinctively however, many companies still do not have any reliable method that would facilitate the decision making processes at their disposal. This article aims at presenting the innovative analytical method- Balanced Critical Factor Index (BCFI) for addressing the need for change in company's operational strategy according to changes in available technology and knowledge. By examining a wide array of indexes, the presented method is expected to suggest the directions of development. The presented method also addresses the challenges of the complex process of decision-making. Moreover, the empirical evidence gathered in the studied case company serves as a source of important feedback regarding the further improvement of the BCFI method.

Opis:
The low-frequency mechanical spectra of lanthanum cobaltite based mixed conducting oxides have been measured using a computer-controlled inverted torsion pendulum. The results indicate that the internal friction spectra and shear modulus depend on the Sr doping contents (x). For undoped samples, no internal friction peak is observed. However, for La0.8Sr0.2CoO3-δ, three internal friction peaks (P2, P3 and P4) are observed. In addition to these peaks, two more peaks (P0 and P1) are observed in La0.6Sr0.4CoO3‒δ. The P0 and P1 peaks show characteristics of a phase transition, while the P2, P3 and P4 peaks are of relaxation-type. Our analysis suggests that the P0 peak is due to a phase separation and the P1 peak is related to the ferromagnetic–paramagnetic phase transition. The P2, P3 and P4 peaks are associated with the motion of domain walls. The formation of this kind of domain structure is a consequence of a transformation from the paraelastic cubic phase to the ferroelastic rhombohedral phase. With partial substitution of Fe for Co, only one peak is observed, which is discussed as a result of different microstructure.

Opis:
A fluorine-containing acrylate copolymer emulsion was prepared in this study, which was applied to finishing linen fabric. Dodecafluloroheptry methacrylate (G04) was used as a modified monomer, butylacrylate (BA) and methylacrylate (MMA) as soft and hard monomers.respectively, and acrylic acid as a functional monomer. Structure and properties of the products were characterised and analyzed by FTIR, TEM, PSD and CA measurements, respectively. The water and air permeability as well as the breaking force of the fabric treated were also investigated. The results showed that the fluorine-containing acrylate copolymer emulsion obtained had a core-shell structure, and the microsphere was of nanoscale size. Because of the latex film on the fabric surface, it became smooth and flat. And the increase in G04 was beneficial to the mechanical properties, waterproofness and antifouling ability of the linen fabric. When the content of G04 were increased from 0% to 20%, the water in the linen sample and hexadecane contact angles to the copolymer film increased from 113.02° to 136.08° and from 65.1° to 87.6°,respectively. Furthermore the breaking force of the linen samples was enhanced from 648 N to 721N. However, the increasing content of G04 had negative effects on the flexural rigidity as well as water and air permeability of the fabric, which were essential requirements for the fabric’s application. However, the wash resistance was excellent and the wear-resistance of the finished linen fabric was better than the unfinished linen fabric.
W pracy przygotowano emulsję kopolimeru akrylanowego zawierającą fluor, którą następnie zastosowano do wykańczania tkanin lnianych. Jako modyfikowany monomer zastosowano metakrylan dodekafluoroheptan (G04), a jako miękkie i twarde monomery użyto akrylan butylu (BA) i akrylan metylu (MMA), a kwas akrylowy jako monomer funkcjonalny. Strukturę i właściwości produktów scharakteryzowano i przeanalizowano za pomocą pomiarów FTIR, TEM, PSD i CA. Przebadano również przepuszczalność wody i powietrza oraz siłę zrywania tkaniny poddanej obróbce. Wyniki wykazały, że otrzymana fluorowa emulsja kopolimeru akrylanowego miała strukturę rdzeń-otoczka, a mikrosfera miała rozmiar w nanometrach. Ze lateksowej powłoce tkanina stała się gładka i matowa. Stwierdzono, że wzrost G04 wpływa korzystnie na właściwości mechaniczne, wodoodporność i zdolność przeciwporostową tkaniny lnianej. Zwiększenie zawartości G04 spowodowało wzrost kąta zwilżania, a siła zrywania próbek zwiększyła się z 648 do 721 N. Jednak wzrastająca zawartość G04 miała negatywny wpływ na sztywność zginania, a także przepuszczalność wody i powietrza tkaniny, które były zasadniczymi cechami wymaganymi dla aplikacji tkaniny. Jednakże odporność na pranie i zużycie była lepsza w przypadku próbek powleczonych.
