Towards understanding dynamic design change propagation in complex product development via complex network approach

Design change propagation is a primary source of risk and innovation in complex product (CP) development. Soundly predicting and managing the design change propagation have become critical issues. Dynamicity is the non-negligible nature of design change propagation. However, existing specific case studies and static predicting methods are inadequate to analyze the dynamicity quantitatively. Here, a general model based on complex network is developed to depict the dynamic design change propagation. Numerical simulations are conducted to explore the general law of the propagation and investigate the influences of design change tolerance capacity distribution ( ), attack strategies, and recovery capacity ( ). The results show that the model can well portray the real design change propagations. The dynamic design change propagation can be controlled by adjusting the parameter , , and . A new indicator is proposed to represent the robustness of the CP network, which is negatively related to β and positively related to γ. The influences of attack strategies and recovery capacity decrease with the increase of β. The cost-effective trade-off criteria to conclude the design change propagation within limited time are provided. This paper provides a basic framework to understand the dynamic design change propagation in CP development.
International Conference on Technologies and Materials for Renewable Energy , Environment and Sustainability , TMREES 15 Simulation and modeling of structural stability , electronic structure and optical properties of ZnO

We propose a generalized gradient approximation simple and effective Engel-Vosko (GGA-EV) to calculate the structural, electronic, optical properties of ZnO phases, namely, wurtzite, zincblende structures using an implementation of the FP method (L) APW in the framework of the density functional theory (DFT). For Choosing a good exchange and correlation potential for effective treatment of the excited state properties such as electronic band structure is necessary density functional. To validate our approach, we compare the results to those obtained using the parameterized generalized gradient approximation of Perdew et al. (GGA-PBE). We calculated the band structure, density of states, dielectric function, reflectivity, refraction index and absorption coefficient. GGA-EV yielded a wider valence band and narrower d-band in comparison to GGA-PBE. Thus an improved the energy band gap that has been caused by repulsion between the states of Zn-d and O-p states which resulted a large separation by GGA-EV. Our calculations show that the edges of the optical absorption, refraction index and reflectivity for GGA-EV are better in comparison toGGA-PBE. © 2015 The Authors. Published by Elsevier Ltd.

Association Between the Right Ear Advantage in Dichotic Listening and Interaural Differences in Sensory Processing at Lower Levels of the Auditory System in Older Adults

Supplemental Digital Content is available in the text. Objective: Current evidence suggests that an enhanced right ear advantage (REA) in dichotic listening (DL) among older adults may originate from age-related structural changes in the corpus callosum and age-related decline in cognitive processes. Less is known about the effect of information processing at lower portions of the auditory system on DL performance. The present study investigates whether interaural differences (ID) in sensory processing at lower levels of the auditory system are associated with the magnitude of the REA in DL among older adults. Design: Sixty-eight older adults participated in the study. Participants were assessed with a DL test using nonforced (NF) and forced attention paradigms. Hearing sensitivity, transient-evoked otoacoustic emission (TEOAE), contralateral suppression of TEOAE, a proxy measure of medial olivocochlear activation, and auditory brainstem response to speech stimuli (speech-ABR) were tested in both ears separately. The ID in sensory processing at lower levels of the auditory system was derived by calculating the difference between the RE and LE for each auditory measure. Bivariate and multivariate regression models were performed. One multivariate model for each DL paradigm (NF and forced attention) was independently constructed. Measures of cognitive speed of processing and cognitive flexibility were accounted for in the regression models. Results: For both multivariate regression models, ID in pure-tone thresholds and ID in MOC suppression of TEOAE were significantly associated with the magnitude of the REA for DL among older adults. Cognitive measures of speed of processing and cognitive flexibility also contributed to the magnitude of the REA. Conclusion: These results suggest that ID in sensory processing at lower levels of the auditory system account, at least in part, for the increased magnitude of the REA in DL among older adults.
Split Parallel Semibridge Switching Cells for Full-Power-Range Efficiency Improvement

This article proposes a positively coupled inductor (PCI) based paralleling scheme for basic semibridge switching cells, which are formed by power MOSFETs and diodes. Both the semibridge switching cells and the inductors are split into two parallel parts, and thus, a small differential mode (DM) inductance is formed between the midpoints of the parallel semibridge switching cells. A time-delay-based modulation strategy is applied to generate a controllable circulating current, which enables all active switches to achieve the zero-current switching (ZCS) or zero-voltage switching, and all diodes to achieve ZCS turn-off. Accordingly, the switching loss and the reverse-recovery loss can be significantly reduced. The operating principle of the proposed paralleling scheme is characterized by two complementary operation modes: desynchronized mode with soft-switching (lower switching loss) and synchronized mode with lower conduction loss. Compared with conventional soft-switching schemes, this solution features zero auxiliary switches, constant switching frequency, and improved full-power-range efficiency enabled by the dual operation modes. Furthermore, design guidelines of the PCI are presented where a novel winding arrangement is proposed and verified to obtain a controllable DM inductance. The operation principles and advantages of the proposed paralleling structure are comprehensively validated on both buck and boost dc–dc converters with Si/SiC power MOSFETs and diodes.
Reflectance Transformation Imaging (RTI) for Documenting Changes through Treatment of Joseon Dynasty Coins

In this paper we present RTI as a documentation tool for visualizing and recording the treatment of coins. RTI, a computational photograph technique based on raking light images, allows interactive re-lighting for vision. Virtual light enhances surface details to examine morphological difference. Stages of conservation treatment were recorded to enhance characteristic features of the relief upon the coin surface and detect and identify weathered characters. Patina removal and consolidation were documented along with the original state. A significant difference in normal and surface texture was observed using RTI viewer and filters. Specular enhancement and normal visualization results were effective for detecting the change of morphology and reflectivity. Characters submersed by thick patina were revealed in Coin 3. Two hidden characters were detected as ‘元’ and ‘訓’. Another illegible character which was previously not regarded as an inscription was discovered. Also, verification of each treatment stage was done to examine whether any foreign material was sufficiently removed. These documentation images indicate that RTI is a promising tool to support manual recording and furthermore allow detection of areas difficult to visualize through the human eye.

Bioconversion Process of Barley Crop Residues into Biogas—Energetic-Environmental Potential in Spain

Barley fields reach 1.7 million hectares in Spain, of which 320,000 are used to produce malt, generating 450,000 tons of crop residue from barley intended for malt production. One way to treat this waste in an environmentally sound, energy-sustainable and economically cost-effective manner is anaerobic digestion. The biogas generated can be used as fuel and as a renewable source of energy (providing a solution to the energy supply problem from an environmental point of view). It has been shown that, when treated along with sludge from a Upflow Anaerobic Sludge Blanket (UASB) reactor, the crop malt residue produces about 1604 NmL of biogas per 100 g; with a content in methane of 27.486%. The development of the process has been studied with a novel indicator, hydrogen generation, and it has been determined that the process takes place in two phases. It has been demonstrated that this solution is beginning to be energy-efficient and therefore to produce energy for external uses in regions that have at least 6000 hectares of planted barley. At best, it can be considered, in a given region, the equivalent of a 115 MW power plant. It could supply energy to 10 thousand homes per year. Therefore, it is considered an energy-efficient solution that com-plies with the Sustainable Development Goals #1, #7, #10, #12 and #13. It guarantees access to energy in isolated areas or with supply problems, and results in a 55.4% reduction in emissions of equivalent-CO2 (which equals 38,060 tons of equivalent-CO2 in Spain).
Integrated statistical and decision models for multi-stage health care audit sampling

Health care audits are crucial in managing the government insurance programs that are estimated to have losses amounting to billions of dollars every year. Statistical methods such as sampling have long been used to handle their size and complexity. Sampling from health care claims data can benefit from multi-stage approaches, especially when the evaluation of the tradeoffs between precision and cost is important. The use of decision models could facilitate health care auditors and policy makers make the best use of these sampling outputs. This paper proposes an integrated multi-stage sampling and decision-making framework that enables auditors address the tradeoffs between audit costs and expected overpayment recovery. We illustrate the framework and discuss insights utilizing a variety of overpayment scenarios for payment populations including U.S. Medicare Part B claims payment data.
An Efficient and Optimized Converter for Fast Binary to Decimal Conversion

ABSTRACT Decimal converter plays an essential role in decimal arithmetic operations. A decimal converter is used to convert binary partial products to Binary Coded Decimal. Here, the use of the converter cell decreases the delay of operation. In contrast to the previous shift + add3 implementations, the proposed cell is much more efficiently optimised due to which the speed of the overall conversion process is increased. The proposed cell shows an improvement in the delay of 9.33 and a power-delay product of 11.96 when compared to the previously proposed work. So, the proposed work can be a better substitute where faster conversions are required.
Characterization and Phylogeny of Fungi from Industrial Wastewater Using Highly Conserved Multiple Gene Loci

The aim of this study was isolation and molecular characterization of fungi from untreated industrial effluent by multigene phylogenetic analyses. The Fungi isolated were characterized based on PCR amplification and genomic sequencing of the internal transcribed spacer region (ITS), partial β-tubulin (Ben A), calmodulin (CaM), and DNA-directed RNA polymerase second large subunit (RPB2) genes, along with morphological characterization and species diversity. Fungal DNA extraction kits and primers sets for the selected genes were purchased and used following the manufacturer’s instructions. The obtained sequences were subjected to BLAST analysis and the corresponding fungal isolates were assigned species names after comparison with representative sequences available in GenBank. All the sequences from this study were deposited in GenBank and the accession number assigned. Phylogenetic trees of the fungal isolates were drawn for each gene by the Maximum Likelihood method using MEGA 7.0 software. Fifteen (15) Fungi species belonging to four genera of Aspergillus, Penicillium, Fusarium and Trichoderma with Aspergillus as the predominant genus were identified.
Solar Thermal Conversion of Plasmonic Nanofluids: Fundamentals and Applications

Plasmonic nanofluids show great interests for light-matter applications due to the tunable optical properties. By tuning the nanoparticle (NP) parameters (material, shape, and size) or base fluid, plasmonic nanofluids can either absorb or transmit the specific solar spectrum and thus making nanofluids ideal candidates for various solar applications, such as: full spectrum absorption in direct solar absorption collectors, selective absorption or transmittance in solar photovoltaic/thermal (PV/T) systems, and local heating in the solar evaporation or nanobubble generation. In this chapter, we first summarized the preparation methods of plasmonic nanofluids, including the NP preparation based on the top-down and bottom-up, and the nanofluid preparation based on one-step and two-step. And then solar absorption performance of plasmonic nanofluids based on the theoretical and experimental design were discussed to broaden the absorption spectrum of plasmonic nanofluids. At last, solar thermal applications and challenges, including the applications of direct solar absorption collectors, solar PT/V systems, solar distillation, were introduced to promote the development of plasmon nanofluids.
Thermally Reduced Graphene Oxide Nanohybrids of Chiral Functional Naphthalenediimides for Prostate Cancer Cells Bioimaging

This study reports on the supramolecular assemblies formed between planar carbon systems (PCSs) such as thermally reduced graphene oxide (TRGO) and its small‐molecule model system coronene and a series of d‐ and l‐α amino acid derivatized naphthalenediimides (NDIs) where the halogen substituents (X = F, Cl, Br, I) are varied systematically. Confocal fluorescence microscopy of NDIs, NDI•coronene, and NDI•TRGO complexes is performed proving the uptake and stability of such complexes in the cellular environment and suggesting their potential as prostate cancer imaging agents. 1H NMR and UV–vis spectroscopy studies support the formation of charge transfer complexes whereby the increasing polarizability and general electronegativity of the aryl halide substituted at the NDI periphery influence the magnitude of the association constants in the ground state between NDI and coronene. Complexation between NDIs and PCSs also results in stable photoexcited assemblies within the solution (coronene) as well as the dispersed phased (TRGO). Fluorescence emission titrations and 2‐photon time correlated single photon counting measurements suggest the existence of dynamic quenching mechanisms upon the excitation of the fluorophore in the presence of the carbon substrates, as these methods are sensitive proves for the subtle changes in the NDI environment. The series of halogenated species used exerts supramolecular control over the degree of surface assembly on the TRGO and over the interactions with the coronene molecule, and this is of relevance to the assembly of future biosensing platforms as these materials can both be viewed as congeners of graphene. Finally, MTT assays carried out in PC‐3 cells demonstrate that the stable noncovalent functionalization of TRGO and coronene with either l or d NDIs remarkably improves the cellular viability in the presence of such graphene‐like materials. These phenomena are of particular relevance for the understanding of the direct donor–acceptor interactions in solutions which govern the design of nanomaterials with future biosensing and bioimaging applications.
The Informational Consequences of Good and Bad Mergers

M&As have informational consequences beyond their immediate effects on stock prices. We find that acquirers receiving a positive market reaction to their M&A announcements experience an increase in the richness of their information environment, consistent with the theoretical predictions of Dow et al. (2017) [Dow, James, Itay Goldstein, and Alexander Guembel. 2017. “Incentives for Information Production in Markets Where Prices Affect Real Investment. ” Journal of the European Economic Association 15 (4): 877–909]. Such acquirers attract more informed trading and more analysts in the post-announcement period. Their investments also become more sensitive to the information revealed in their share prices.

The significance result of the paired t-test is 0.000 (less than 0.005) supported by the posttest mean score higher than the pretest. The results of student responses stated that 96.5% chose the category very good or very practical to use. The conclusion of this study states that the media board game "Labyrinth in the Forest" that has been developed is valid, practical, and effective for the learning process, especially junior high school students on number material.
The business of philanthropy: Challenges in measuring the value of cultural giving

Corporationsareunderincreasingpressuretoprovideinfor-mation about their corporate social responsibility activities. However, there is limited work on how firms measure the value of their philanthropic giving. The value of a philanthropic act can be difficult to ascertain as it often relates to unique goods that do not have a market value. The paper examines the processes a sample of (mainly family-run) private corporations follow to value their donations to a not-for-profit cultural festival. The findings suggest that while giving to the festival is seen as a contribution to the local community, there are additional motivations for donating. Moreover, the firms do not attempt to formally assess the value of their act, which they believe is hard (if not impossible) to measure. Our case highlights a more complex system influencing philanthropic acts of private firms. However,unlikeourwork,thesestudiesdonotfocusonthereasonswhyorganisationsdonatetofestivalsandwhether or not they assess the impact of their giving. Our study also provides fresh insights into how businesses deal with the pressure to account for all of their activities, including their philanthropic giving (Miller & Power, 2013; Power, 2009).
Older workers imagining retirement: the collapse of agency, or freedom at last?

Abstract Images of what retirement is and ought to be are changing. Older workers are being encouraged to work for longer, at the same time, older adults increasingly voice expectations of a ‘third age’ of active engagement and new life prospects. In this article, we draw on the literature on older workers’ work patterns and retirement transitions (noting push/pull/stay/stuck/jump factors), and on scholarship on the changing social meaning of old age, most importantly the notions of a ‘third’ and ‘fourth’ age. The analysis is based on qualitative interviews with 28 employees in the private sector in Norway, aged between 55 and 66 years. Based on the interviews, we propose three ideal-typical approaches to the work–retirement transition: ‘the logic of deadline’, ‘the logic of negotiation’ and ‘the logic of averting retirement’. The ideal-types are defined by the degree to which informants assume agency in the workplace, their orientation towards work versus retirement and the degree to which they expect to exercise agency in retirement. We emphasise how retirement decisions are informed by notions of the meaning of ageing, while also embedded in relationships with employers and partners.
Social solidarity as a dimension of transitional justice: the case of Cartography and Identification of Mass Graves in post-conflict Colombia

ABSTRACT The field of transitional justice lacks a comprehensive understanding to the role that social solidarity plays in transitional justice contexts. There is a lack of knowledge of the means through which victims can exercise their social agency to explore mechanisms of reparation beyond truth commissions, tribunals, and trials. This article argues that social solidarity is a crucial dimension and a novel perspective from which to develop transitional justice processes from a victims’ point of view in post-conflict societies. Employing a participative action research method, this article’s importance rests in the idea that Colombian victims’ groups from Eastern Antioquia view social solidarity as a crucial dimension of transitional justice in developing the project Cartography and Identification of Mass Graves. It establishes that this effort is a powerful novel mechanism to claim justice, reparation, recognition, and guarantees of non-recurrence from an unofficial angle. It demonstrates that comprehending social solidarity as a vital dimension of transitional justice stresses the importance of victims’ social agency to conduct collaborative collective actions in order to support inclusive processes of disarmament, demobilisation, and reintegration (DDR) beyond official agendas and narratives.
The Determinants of Economic Growth: Empirical Study of 10 Asia-Pacific Countries

The purpose of this research to examine influence several independent variables, especially corruption, foreign direct investment (FDI), population growth, and government expenditure on the economic growth of 10 Asia-Pacific countries, and prove the hypothesis of the sand wheels theory whether corruption causes a decline and a slowdown in economic growth. This study uses panel data. The results showed that the variables of corruption have a negative impact on economic growth, foreign direct investment (FDI), and government expenditure have positives that significantly affect the level of economic growth in 10 Asia-Pacific countries. However, population growth does not significantly affect economic growth. The result implies that corruption has a negative effect on economic growth in 10 Asia-Pacific countries. Such an outcome provides evidence and confirms the hypothesis that corruption can sand the wheel of an economy. Countries must eradicate all forms of corruption and maintain a conducive investment climate so that there is a level of trust, especially in the Asia-Pacific countries, to create productive economic growth.
