Design of compact dual‐band bandpass filter using short stub loaded resonator

Compact dual‐band bandpass filter using short stub loaded resonators is presented in this letter, the proposed resonator possesses the advantage that its center frequency of the even mode can be flexibly controlled, whereas that of the odd‐mode is fixed. A dual‐band filter using pseudo‐interdigital SSLR is implemented with three transmission zeros. Meandering SSLR is proposed to obtain independently controlled bandwidth at each band. Two experimental examples of filters have been designed and fabricated, good agreements are shown between the simulation and the measurement. The bandpass filters have very smaller area in comparison of previous works. © 2009 Wiley Periodicals, Inc.

Exploring views on design and service factors for improving housing development green space quality in Taiwan

ABSTRACT The objective of this study was to learn views from design teams, housing developers and users for housing development green space quality that could best enhance occupant well-being and real-estate value addition. Through literature review, 26 landscape design and service factors were identified and tested via a questionnaire survey conducted in Taiwan. Participants (N = 380) evaluated the importance level of the proposed factors with five-point Likert scale. Friedman Ranking Test and Kruskal-Wallis Test were used to analyse data. The results showed that ease of maintenance, regulation compliance and energy saving were the top factors for all participants. These are the economic advantage, bidder characteristics and environmental awareness concerns. Life cycle design and water retention and detention factors were evaluated as the critical factors from the potential housing developer and buyers. Green infrastructure connection and neighbourhood connection were ranked as very important factors for landscape architects. Landscape architects to practice with license and use LIM/BIM in project was particularly expected by the potential housing buyers with high importance level. The preliminary findings of this research can assist public housing agency and private developers for policy and decision making effectively in future housing development green space projects.
Correlation of dynamic characteristics of a super‐tall building from full‐scale measurements and numerical analysis with various finite element models

The Di Wang Tower located in Shenzhen has 79 storeys and is about 325 m high. Field measurements have been conducted to investigate the dynamic characteristics of the super‐tall building. In parallel with the field measurements, seven finite element models have been established to model the multi‐outrigger‐braced tall building and to analyse the effects of various arrangements of outrigger belts and vertical bracings on the dynamic characteristics and responses of the Di Wang Tower under the design wind load and earthquake action. The distributions of shear forces in vertical structural components along the building height are also presented and discussed. The results from detailed modelling of group shear walls with several types of finite elements are addressed and compared to investigate various modelling assumptions. Finally, the performance of the finite element models is evaluated by correlating the natural frequencies and mode shapes from the numerical analysis with the finite element models and the field measurements. The results generated from this study are expected to be of interest to professionals and researchers involved with the design of tall buildings. Copyright © 2004 John Wiley & Sons, Ltd.
Effect of microcracking on the shrinkage cracking and durability performance of cement-treated macadam material

ABSTRACT This study systematically investigates the effect of microcracking on the shrinkage performance and durability of cement-treated macadam (CTM). Microcracks formed in the early stage of microcracking can reduce reflection cracks generated in semi-rigid base asphalt pavements. The shrinkage characteristics and durability of CTM after microcracking are important to consider in the engineering of the CTM base. In this study, indoor shrinkage tests were conducted on the prepared specimens in ten working conditions, and finite element analysis of the water loss shrinkage of the microcracked CTM was conducted using a cohesive zone model (CZM). The CTM durability after early microcracking was analyzed and evaluated through fatigue tests and freeze–thaw cycle tests. The results showed that the drying shrinkage strain and temperature contraction coefficient of the CTM could be effectively reduced by microcracking. The fatigue life of the CTM decreased with 50% microcracking, but was still within the service requirement. Taking the 104 Chinese road reconstruction project as the research background, microcracking should be conducted 35 d before the freezing period to avoid significantly affecting the frost resistance of the CTM base. This study provides a theoretical basis for the promotion and application of microcracking techniques in practical engineering.
Increasing Human Capital of Coaches—An Investigation Into Individual and Organizational Factors

Coaches play a vital role in providing sports programs. Investing in formal coach education can serve to increase coaches’ human capital, which in turn, has a positive effect on their coaching practice. The present study investigates factors influencing coaches’ intention to get training for their coaching activity on an individual and organizational level. Nationwide online surveys were conducted in Germany on both nonprofit sports clubs and coaches being active within these clubs. Data were analyzed using multilevel regression analysis on a sample of n = 2,384 coaches in n = 1,274 clubs. Results show that especially the expiring validity of the coaching license, aspects of personal development, and low transaction costs are crucial factors for the intention to obtain a qualification. The results lead to several implications for theory and practice. Clubs could enhance the qualification intention and, thereby, the quality of sports programs by appointing a contact person who informs about qualification possibilities.

ETLi: Efficiently annotated traffic LiDAR dataset using incremental and suggestive annotation

Autonomous driving requires a computerized perception of the environment for safety and machine‐learning evaluation. Recognizing semantic information is difficult, as the objective is to instantly recognize and distinguish items in the environment. Training a model with real‐time semantic capability and high reliability requires extensive and specialized datasets. However, generalized datasets are unavailable and are typically difficult to construct for specific tasks. Hence, a light detection and ranging semantic dataset suitable for semantic simultaneous localization and mapping and specialized for autonomous driving is proposed. This dataset is provided in a form that can be easily used by users familiar with existing two‐dimensional image datasets, and it contains various weather and light conditions collected from a complex and diverse practical setting. An incremental and suggestive annotation routine is proposed to improve annotation efficiency. A model is trained to simultaneously predict segmentation labels and suggest class‐representative frames. Experimental results demonstrate that the proposed algorithm yields a more efficient dataset than uniformly sampled datasets.
Different Temporal Stability and Responses to Droughts between Needleleaf Forests and Broadleaf Forests in North China during 2001–2018

Droughts can affect the physiological activity of trees, damage tissues, and even trigger mortality, yet the response of different forest types to drought at the decadal time scale remains uncertain. In this study, we used two remote sensing-based vegetation products, the MODIS enhanced vegetation index (EVI) and MODIS gross primary productivity (GPP), to explore the temporal stability of deciduous needleleaf forests (DNFs) and deciduous broadleaf forests (DBFs) in droughts and their legacy effects in North China from 2001 to 2018. The results of both products showed that the temporal stability of DBFs was consistently much higher than that of DNFs, even though the DBFs experienced extreme droughts and the DNFs did not. The DBFs also exhibited similar patterns in their legacy effects from droughts, with these effects extending up to 4 years after the droughts. These results indicate that DBFs have been better acclimated to drought events in North China. Furthermore, the results suggest that the GPP was more sensitive to water variability than EVI. These findings will be helpful for forest modeling, management, and conservation.
Ground-based Investigation of HOx and Ozone Chemistry in Biomass Burning Plumes in Rural Idaho

Abstract. Ozone (O3), a potent greenhouse gas that is detrimental to human health, is typically found in elevated concentrations within biomass burning (BB) smoke plumes. The radical species OH, HO2, and RO2 (known collectively as ROx) have central roles in the formation of secondary pollutants including O3 but are poorly characterized for BB plumes. We present measurements of total peroxy radical concentrations ([XO2] ≡ [HO2] + [RO2]) and additional trace-gas and particulate matter measurements from McCall, Idaho during August 2018. There were five distinct periods in which BB smoke impacted this site. During BB events, O3 concentrations were enhanced as evidenced by ozone enhancement ratios (ΔO3/ ΔCO) that ranged up to 0.25 ppbv ppbv−1. [XO2] was similarly elevated during some BB events. Overall, quantified instantaneous ozone production rates (P(O3)) were only slightly impacted by the presence of smoke as NOx enhancements were minimal. Measured XO2 concentrations were compared to zero-dimensional box modeling results to evaluate the effectiveness of the Master Chemical Mechanism (MCM) and GEOS-Chem mechanisms during periods of BB influence and overall agreed within 31 %. One period of BB influence had distinct measured enhancements of 15 pptv XO2 that were not reflected in the model output, likely due to the presence of an unmeasured HOx source, quite likely nitrous acid (HONO). To our knowledge, this is the first BB study featuring peroxy radical measurements.

Autoethnography in qualitative studies of gender and organization: a focus on women successors in family businesses

This chapter examines autoethnography as a research method to study women in family business. Prior studies suggest that family businesses may provide a harbour where women have the opportunity to manage existing businesses and create new ventures. Yet, whilst scholars have noted the crucial input of women in the creation, development and continuity of family businesses, their experience as successors is not unproblematic. This chapter argues that the perceived role of women could remain unchallenged unless methods that allow fresh understanding of the complex narratives and emotional components of family business succession are considered. The study presented in this chapter uses an autoethnographic illustration of a son and expected successor of a family business as he reflects on the memories and experiences related to a women becoming the successor of his family in business. This chapter will be of interest to academics who seek new approaches to understand complex gendered relations in family businesses.

The circuit area is reduced to less than 20 percent of conventional transmission line realizations at 4 GHz. Test results are presented for a CPW 10-dB coupler (2 x 2 mm) and an MIC 3-dB Wilkinson divider/combiner circuit (1.75 x 2.75 mm). Good agreement is obtained between measured and modeled results.
Evaluation of a Targeted Next-generation Sequencing Assay for BRCA Mutation Screening in Clinical Samples

Background: While several factors contribute to breast cancer pathogenesis, hereditary breast cancer results from a genetic predisposition. Genes associated with hereditary breast cancer may be divided into high- and low-penetrance genes depending on their risk rates. BRCA1 and BRCA2 are typical high-penetrance genes that increase the risk of developing breast and ovarian cancers upon undergoing mutations. This study aimed to evaluate the clinical performance of BRCAaccuTest TM (NGeneBio, Korea). Methods: BRCAaccuTest TM is a reagent used to produce libraries for analyzing BRCA1/2 genes using next-generation sequencing (NGS), which analyzes blood-derived genomic DNA. Libraries with adapters and barcodes compatible with the Illumina platform were produced. The clinical performance of NGS-based BRCAaccuTest TM in identifying BRCA1/2 mutations was compared with that of the traditional Sanger sequencing method. Both NGS and Sanger sequencing were performed in a single laboratory using archival DNA from blood samples of 212 patients with breast cancer. Results: All target regions amplified were successfully sequenced to obtain a minimum coverage of 20, demonstrating 100 % concordance with the pathogenic single-nucleotide variations and small insertions-deletions previously identified by Sanger sequencing. Conclusions: This study demonstrates the feasibility of using BRCAaccuTest TM to detect the BRCA1/2 mutations with high accuracy.
Printed Newton's egg curved monopole antenna for ultrawideband applications

The edge curve of a planar antenna significantly influences its radiation properties. In this study, a novel egg curve-based design of printed monopole antenna of size 40 × 40 mm 2 is proposed for ultrawideband (UWB) applications. The egg shape of the proposed antennas is obtained by Newton's diverging parabolas curve referred in this study as Newton's egg curve. The design equations of the proposed antenna are developed. The variation in impedance bandwidth (BW) with various parametric variations of design curve is studied. The proposed Newton's egg curved monopole antenna (NECMA) is designed, fabricated and measured to validate the theoretical design. Good agreement between the simulated results and the measured ones is observed. An empirical formula is also proposed to approximately determine the frequency corresponding to the lower edge of -10 dB operating BW. The results show that the proposed NECMA can obtain the measured BW of 116.55% (2.9-11.0 GHz) along with stable gain of about 2.2-2.9 dBi. The proposed antenna exhibits almost omnidirectional radiation patterns with low cross polarisation in all directions and consistent group delay over the entire UWB bandwidth (3.1-10.6 GHz).
The Effect of Governmental Health Measures on Public Behaviour During the COVID-19 Pandemic Outbreak

Background: The coronavirus disease 2019 (COVID-19) pandemic resulted in radical changes in many aspects of life. To deal with this, each country has implemented continuous health measures from the beginning of the outbreak. Discovering how governmental actions impacted public behaviour during the outbreak stage is the purpose of this study. Methods: This study uses a hybrid large-scale data visualisation method to analyse public behaviour (epidemic concerns, self-protection, and mobility trends), using the data provided by multiple authorities. Meanwhile, a content analysis method is used to qualitatively code the health measures of three countries with severe early epidemic outbreaks from different continents, namely China, Italy, and the United States. Eight dimensions are coded to rate the mobility restrictions implemented in the above countries. Results: (1) Governmental measures did not immediately persuade the public to change their behaviours during the COVID-19 epidemic. Instead, the public behaviour proceeded in a three-phase rule, which is typically witnessed in an epidemic outbreak, namely the wait-and-see phase, the surge phase and the slow-release phase. (2) The strictness of the mobility restrictions of the three countries can be ranked as follows: Hubei Province in China (with an average score of 8.5 out of 10), Lombardy in Italy (7.125), and New York State in the United States (5.375). Strict mobility restrictions are more likely to cause a surge of population outflow from the epidemic area in the short term, whereas the effect of mobility restrictions is positively related to the stringency of policies in the long term. Conclusion: The public showed generally lawful behaviour during regional epidemic outbreaks and blockades. Meanwhile public behaviour was deeply affected by the actions of local governments, rather than the global pandemic situation. The contextual differences between the various countries are important factors that influence the effects of the different governments’ health measures.
Examination of Vehicle Motion Characteristics of a Maglev Train Set Using a Reduced-scale Model Experiment Apparatus

This paper focuses on the vehicle dynamics of superconducting magnetically levitated (Maglev) vehicles as a train set, and reports results of computer simulation as well as results of experiments using a reduced-scale Maglev model vehicle dynamics experiment apparatus (MAGMOX). The previously constructed MAGMOX consisting of a single car was expanded to form a train set comprising several cars. The computer simulations and MAGMOX experiments produced results that demonstrated their effectiveness in reproducing testing conditions of the full-scale Maglev system that are difficult to achieve on an actual full-scale vehicle due to vehicle structure constraints and rigging space.
A surgical risk reduction approach to reduce global process safety risk: The “PSM gamma‐knife”

Businesses with more than one site strive to minimize operational variability across their entire organization. However, uniformly implementing company‐wide standards is difficult because each site maintains its own personality—its own culture. When a business strives to reduce its global process safety risk, a significant incident that exposes a particular site's weakness may result in a simple corporate decision forcing all sites to implement the same process safety improvement. This article shares the basic concept and the novel use of a risk minimization tool, commonly used to reduce financial risks in an investment portfolio, to help decision‐makers minimize their multisite, global process safety risk without adding undue stress on the rest of the organization. This approach helps quantify each individual site's process safety risks into a global business process safety risk model, uses a Monte Carlo simulation to determine which site‐specific factors contribute the most to the overall business risk, and then helps decision‐makers prioritize and choose site‐specific risk reduction efforts that minimizes the global risk. The global process safety risk reduction model used to show how to use this approach is based on a simplified risk equation containing site‐specific terms for frequency, consequence and operational discipline. Often the most contentious term in risk estimating is the frequency, especially with significant scenarios that have never happened before and, hence, have a very low likelihood. The beauty of the Monte Carlo simulation is that the user can account for the uncertainty in the frequency by choosing a frequency probability function based on a range of possible best‐ to worst‐case consequence scenarios. From the surgical perspective, a person (the whole organization) with cancer is often adversely affected when treated with chemotherapy. The results from this approach, using the image of a “PSM Gamma Knife,” show how selective site‐specific risk reduction treatments specifically address each site's process safety risk to help reduce the overall risk without adversely affecting the health of the whole organization. © 2012 American Institute of Chemical Engineers Process Saf Prog, 2012
Design of 12-slot 10-pole Permanant Magnet Flux-Switching Machine with hybrid excitation for hybrid electric vehicle

Permanent Magnet Flux Switching Machine (PMFSM) is an interesting machine for electric propulsion system application because of its high power density and robust rotor structure. This paper presents some design optimization studies on PMFSM with hybrid excitation applied to a hybrid electric vehicle, which have all active parts in the stator. A reduction of permanent magnet material for a constant torque and an extension in speed and torque ranges are chosen for the optimization aims. For this purpose, the original PMFSM, which has been already proposed by other researchers, is firstly just transformed to the target machine size and then, the design problem is made clear. To obtain the necessary drive performances, some design optimization are executed by means of FEA-based trial and error. As a result, it shows the proposed design is suitable for high speed HEV.
