Abstract :

The usability now serves as a fundamental quality of a computational device, e.g. smartphone. Moreover, the smartphone has firmly embedded into our daily life as an indispensable part, so the context and style that user may interact with them are largely different from a decade ago. Nowadays, testing usability with end user has become a common sense. Thus, how valid a usability evaluation method could assess the ‘extent to which a product can be used by specified users’ (ISO 9241-11) to facilitate software design becomes an interesting question to explore. In this research, three usability evaluation methods are compared. Among these methods, IsoMetrics is a standard questionnaire aiming at offer usability data for summative and formative evaluation; SUMI aims to assess quality of software product from end users perspective; User Model Checklist is a method based on user’s cognition-motor chain in specific tasks. The coverage and amount of usability issues, user’s effort of evaluation and software developer’s feedback on evaluation result are compared under a simulated usability test on SMS function with a smartphone. The result indicate that User Model Checklist could cover 90.4% of the usability issues found by IsoMetrics and SUMI, while 26.3% usability issues found by User Model Checklist could not be covered by IsoMetrics and SUMI. Users put highest effort on accomplish IsoMetrics and lowest effort on User Model Checklist. Moreover, the feedbacks from the developers show that the User Model Checklist requires lower usability knowledge, offers clearer improvement points and supports detailed design better. © 2019, Springer Nature Switzerland AG.

Abstract :

Carbon/carbon (C/C) composites are considered as one of the most promising materials in structural applications owing to their excellent mechanical properties at room and high temperature. Considering their service environments, investigations on the quasi-static and dynamic mechanical properties of C/C composites at different temperatures are of great importance. In this work, the compressive strengths and failure modes of C/C composites under different strain rates and at different temperatures were studied in detail. The experiments were conducted at room temperature and 300 °C with the strain rate controlled over a wide span of 2.08 × 10−4 −1862.09 s−1. Results showed that the failure modes of the C/C composites were obviously influenced by the strain rate and temperature, and the compressive strength of the C/C composites significantly increased with the increase of strain rate or temperature. In addition, relationships between the dimensionless compressive strength and strain rate were first established for C/C composites by using a bilinear fitting algorithm at different temperatures. The results can be conveniently used to predict the compressive strength of C/C composites in engineering applications. © 2018 Elsevier Ltd

Abstract :

Laminar natural convection in a vertical annulus with inner wall covered by a porous layer is numerically studied in this paper by using a multiple-relaxation-time lattice Boltzmann (MRT LB) model for the axisymmetric thermal flow in porous media at the representative element volume (REV) scale. The effects of the Rayleigh number, Darcy number, thermal diffusivity ratio and thickness of the porous layer on the overall heat transfer rate are investigated. It is found that wrapping with a porous layer can serve as a useful tool for heat transfer augmentation or reduction, which is strongly depending on the physical parameters, especially the Darcy number and thermal diffusivity ratio. © 2018

Abstract :

Multispectral pedestrian detection is an emerging solution with great promise in many around-the-clock applications, such as automotive driving and security surveillance. To exploit the complementary nature and remedy contradictory appearance between modalities, in this paper, we propose a novel cross-modality interactive attention network that takes full advantage of the interactive properties of multispectral input sources. Specifically, we first utilize the color (RGB) and thermal streams to build up two detached feature hierarchy for each modality, then by taking the global features, correlations between two modalities are encoded in the attention module. Next, the channel responses of halfway feature maps are recalibrated adaptively for subsequent fusion operation. Our architecture is constructed in the multi-scale format to better deal with different scales of pedestrians, and the whole network is trained in an end-to-end way. The proposed method is extensively evaluated on the challenging KAIST multispectral pedestrian dataset and achieves state-of-the-art performance with high efficiency. © 2018

Abstract :

The objective of this paper is to develop a criterion to predict the onset of heat transfer deterioration (HTD) for supercritical CO2 heat transfer. A new mechanism is proposed by assuming supercritical pseudo-boiling. Before bulk fluid reaches pseudo-critical temperature (Tpc), the tube cross-section contains a vapor layer and a liquid-like fluid. The saturation temperature interface is defined at T = Tpc, inside and outside which are a vapor layer (T > Tpc) and a subcooled liquid (T < Tpc). The subcritical boiling number is extended to supercritical “boiling” number, defined as SBO = qw/(Gipc), where qw, G and ipc are heat flux, mass flux, and CO2 enthalpy at Tpc, respectively. SBO, by coupling the density ratio between “liquid” and “vapor” represents the competition between vapor expansion induced momentum force and inertia force. The experiment of supercritical CO2 heat transfer is performed in a 10.0 mm inner diameter tube, covering ranges of P = 7.5–21.1 MPa, G = 488–1600 kg/m2s and qw = 74–413 kW/m2. Surprisingly, the onset of HTD is found to occur at a critical SBO which is 5.126×10−4 and the critical heat flux is expressed as qCHF=5.126×10−4Gipc. It is shown that our new criterion is also suitable for other experiments reported in literature, providing a general guidance to design and operate S–CO2 heaters to avoid HTD. © 2018 Elsevier Masson SAS

Abstract :

Smartphone is nowadays the most prevalent computer system, thus a lot of attention from academia and industries has been put to evaluate its quality of use. However, Smartphone has more complex interaction modes and usage scenarios than PC and laptop. And therefore assessing its quality using a conventional usability evaluation is not sufficient. Meanwhile, the mental load serves as an acknowledged index of effort that operators have put in human-machine interaction, especially under high-demanding context. Mental load contains a set of parameters in multiple dimensions, such as primitive task performance, biological measurement(s) and subjective mental load scale, which assesses the efforts of tasks under a particular environment and operating conditions. Thus, it is suitable for evaluating complex mental work, and may indicate the use of Smartphones. The aim of this paper is to apply a multi-dimensional method to assess the mental load of users, and find out which measurement(s) is the most suitable one to evaluate the efforts for using a smartphone. During this study, the effort on conducting tasks with four difficulty levels were assessed using measurements in three dimensions, which were (1) user performance (task accomplishment and secondary task), (2) subjective rating (NASA-TLX scale) and (3) physiological function (EDA). The values of these measurements were compared across novice, average and skilled users. The results show that: task duration and number of usability error are significantly related with mental load and change with the difficulty level of tasks; in subjective rating, Mental Demand, Effort and Frustration were highly related with mental load. © Springer Nature Switzerland AG 2019.

Abstract :

Relying on resource dependence theory and transaction cost economics, this article discusses the important role of alliance governance as a mediating mechanism in the relationship between market orientation and innovation, and compares the differences between the influences of different dimensions. The article aims to reveal the influence mechanism of different types of alliance governance on the relationship between market orientation and innovation. Based on a sample of 122 Chinese manufacturing enterprises, the article finds that: (1) contractual governance will increase when customer orientation and competitor orientation become higher, and contractual governance will affect radical innovation in a U-shaped way; (2) trust governance will increase when inter-functional coordination become higher, and trust governance has a positive impact on both radical innovation and incremental innovation (II).

Single and multi-objective optimizations of rotary regenerative air preheater for coal-fired power plant considering the ammonium bisulfate deposition EI Scopus

Abstract&Keyword Cite

Abstract :

Although much work has been done on the optimization of the recuperative heat exchangers, little attention has been paid to the optimization of rotary regenerative air preheater (RAPH) in coal-fired power plants. It is known that the ammonium bisulfate deposition (ABS) can adversely affect the safe operation of RAPH, so an improved Radian number was proposed to estimate the impact of ABS in the optimization of RAPH. The thermal hydraulic calculation program integrated with genetic algorithms was developed to conduct optimizations of RAPH. The design parameters included rotor radius, each fluid sector angle and each matrix layer height. The multi-objective optimization was carried out to maximize the effectiveness and to minimize the pressure drop from the perspective of users, while the single-objective optimization was performed to minimize the weight of the heat transfer elements from the perspective of manufacturers. The improved Radian number is more reasonable to reflect the ABS deposition compared with the original Radian number. The designer can estimate the ABS deposition status using the improved Radian number not only in the operating process but also in the design process of RAPH. The range of optimal solution becomes smaller but the rank of the Pareto solution stays unchanged with the decrease in the restriction of improved Radian number. The optimization with larger rotor radius restriction could obtain better Pareto results. The total weight of heat transfer elements could be reduced by at least 26.5% compared with that of the original design by using genetic algorithm. © 2018

Abstract :

The anuran Xenopus laevis has been studied for decades as a model for vertebrate cell and developmental biology. More recently, the highly related species Xenopus tropicalis has offered the opportunity to carry out genetic studies due to its diploid genome as compared to the pseudo-tetraploid Xenopus laevis. Amphibians undergo a biphasic development: embryogenesis to produce a free-living tadpoles and subsequent metamorphosis to transform the tadpole to a frog. This second phase mimics the so-called postembryonic development in mammals when many organs/tissues mature into their adult form in the presence of high levels of plasma thyroid hormone (T3). The total dependence of amphibian metamorphosis on T3 offers a unique opportunity to study postembryonic development in vertebrates, especially with the recent development gene editing technologies that function in amphibians. Here, we first review the basic molecular understanding of the regulation of Xenopus metamorphosis by T3 and T3 receptors (TRs), and then describe a detailed method to use CRISPR to knock out the TR-coactivator SRC3 (steroid receptor coactivator 3), a histone acetyltransferase, in order to study its involvement in gene regulation by T3 in vivo and Xenopus development.
