Driving comfort for riders and passengers is a keytarget to be achieved. Fluctuations in vehicle loads, bumps,perforated surfaces, and other road damage will greatly affectthe vehicle suspension working system. This study aims tocalculate the vertical dynamic load of the vehicle actually whichoccurs on road construction after through the vehicle wheelsuspension mechanism. The Pneumatic cylinder that was drivenby pressurized air directly weigh on the spring and ShockAbsorber that contained on the wheels of the vehicle. The loadfluctuations of the medium weight category vehicle aredetermined by the regulation of the amount of pressurized airentering into the pneumatic cylinder chamber pushing the pistonand connecting rods. The deviation that occurs duringcompression on the Spring and Shock Absorber, is substitutedinto the vehicle dynamic load equation by taking also themagnitude of the spring stiffness constant, and the fluid or gascoefficient of the damper. The results showed that the magnitudeof the displacement when the compression force worked hassignificantly influenced the amount of vertical dynamic load ofthe vehicle that overlies the road construction. Experimentalresults using pneumatic actuators instead of real dynamic vehicleloads illustrate the characteristics of the relationship betweenwork pressure and dynamic load. If the working pressure of P2(bar) is given great, the vertical dynamic load Ft (N) whichoverloads the structure of the road is also greater. From thegraph shows that shock absorbers have greater ability to reducedynamic load vertically when compared to spring ability.
The Reluctant Feminist: Angela Merkel and the Modernization of Gender Politics in Germany
Authors: Mushaben Joyce Marie
Published: November 2018

Academic studies regarding the impact of various forms of gender representation focus largely on quantitative evidence that women in power can make a difference, downplaying qualitative case studies that can establish causal links between women's participation in government and better policies for women. Analyzing policy changes initiated by Germany’s first female Chancellor since 2005, the paper argues that despite her CDU-affiliation, Angela Merkel has contributed more to gender equality in Germany than all previous chancellors, even though she refuses to label herself a feminist. The author explores three factors shaping Merkel's reluctance to embrace the (western dominated) feminist label, e.g., her socialization under a diametrically opposed GDR gender regime, her preference for data-driven policy learning, her aversion towards “ideological” framing, coupled with a tendency to pursue mixed motives, respectively. The paper concludes with recent examples geared towards leveling the global gender playing-field, attesting to her willingness to embrace transformational representation.

Dialects of the Stieng language
Authors: Le Cuong Khac
Published: November 2018

In comparison with South Bahnaric languages such as Kơho, Mnong, Chrau, Ma, the dialect problem in the Stieng language is not complicated. It shows that the Stieng peoples haven’t changed much in terms of residence or, otherwise, the swidden cultivation did not adversely affect the language’s uniformity. Although there are still many comments on the level of difference between two dialects Stieng Bu Lơ and Stieng Bu Deh, in my opinion, the differences are not big, especially since Vietnam was unified in 1975.

Jinn sacrifice ritual is a type of folk beliefs. It does not only represent the opinions of Ly Son island district residents, Quang Ngai about worldview and outlook on life, but also contains the value of spiritual culture. At the same time, Jinn Sacrifice Ritual functions as ethical education of human life, as well as satisfying spiritual needs of individuals, families and communities. Jinn sacrifice ritual was common invocation used by residents in Ly Son island district, Quang Ngai for the dead in the process of clearance, of hamlet establishment, or for those suffering from sudden death. Jinn sacrifice ritual implementation reflects the islanders’ expectations for Jinn’s protection and support for a happy life safe and sound. Therefore, the Jinn sacrifice ritual in Ly Son island district is carried out not only in the Jinn Pagoga and in the All-Souls Temple in An Vinh commune, Nghia Pagoda in Thon Dong hamlet, Nghia Pagoda in An Hai commune, Nghia Pagoda in An Binh commune, but also in such many other places as Lady Palace in Tay small village, Vinh Hoa in Dong small village in An Vinh commune, Thien Y A Na Lady Palace in Trung Yen, Dong Thanh in Dong small village and So Hoi Dong in Dong Ho, An Hai commune, Vinh An Pagoda in An Vinh commune, etc.
The reality of Vietnamese language teaching and Vietnamese Studies education in Korea
Authors: Le Minh Thi Hong
Published: November 2018

Over 20 years of Korea-Vietnam relationship, Korea has become the biggest investor in Vietnam, and Vietnam the forth on the list of Korea’s most important partners. There are over 135,000 Koreans living in Vietnam and out of 123,000 Vietnamese living and working in Korea, there are 40,000 Vietnamese wives to Korean husbands. Currently, in Korea there are 4 universities that have faculties or departments of the Vietnamese language or of Vietnamese Studies, with a large number of alumni who have successfully found jobs. Demand is higher than supply capacity. Vietnamese proficiency is not only essential to Koreans living and working in Vietnam and Korea-based companies with Vietnamese employees but also will be valuable to children of thousands of Korean-Vietnamese families in the coming years. The Ministry of Education of Korea has just announced a policy stating that the Vietnamese language will be one of the eight second languages in the national university entrance examination, which will bring to Vietnamese language teaching new opportunities and prospects.
Dreams as an archetype in contemporary Vietnamese short stories
Authors: Tran Tuoi Thi
Published: November 2018

Archetypes are understood as ‘great symbols’ deriving from ancient times and arising from the collective unconsciousness. Through my studies, I realize that, in contemporary Vietnamese short stories, dreams can be considered as an archetype. Dreams are coded in conceptual metaphors, in allegorical expressions, and they appear everywhere in the works of many contemporary authors. On the one hand, this trend is the continuation of a traditional source of inspiration in folk and medieval literature; on the other hand, it is characterized by modern senses. Authors experimentally introduce a philosophy in dreams, and expand their creative range through dreams. This study provides a new insight into contemporary Vietnamese short stories under the archetypal lens.

Published: November 2018

The development of social media has dramatically changed the intention to use of the consumer in e-commerce. Based on social network theory, trust transfer theory, and task–technology fit theory, this study proposed and validated a model of intention to use social commerce. Total 230 samples of data which are collected from respondents who have used or intend to use social commerce in Vietnam. The results of structural equation modeling illustrated that three second–order components from six first–order elements in pairs, such as website quality (ease of navigation and quality of service), trust (trust towards members and trust towards community), and social support (information support and community commitment) have structural relationships with intention to use social commerce. The research model explains roughly 83% the intention to use social commerce in Vietnam.

Published: November 2018

Traveling Salesman Problem (TSP) is a problem where each initial route of departure and return path between regions remains the same. The problem with TSP is how to get the optimum results to get the shortest path that will be passed, to solve TSP problems, one way can be by using evolved algorithms. Evolution Algorithm (AE) is a method that uses natural selection as the main idea in solving a particular problem. This algorithm is implemented through computer simulations starting from the individual population that will be randomly generated and then evaluated to achieve the best solution. Random search is included in part of stochastic optimization and global optimization. Random search is a direct search method that does not require derivatives to search for continue domains. The purpose of this study was to see the effect of population initialization with random search on algorithms evolving in TSP optimization. Results of initialization strategy implementation Random search has shown more optimal results compared to pure initialization without using random search. This is due to the initialization searching for space for random initialization.

Published: November 2018

The data showed in this review exposes basic aspects that define organic foods and some factors that influence consumption by the population, ie, its production in the country and the motivations for the consumption of food produced in this system . This way of production, originated in the early decades in the 20th century, nowadays involves environmental, social and health aspects. Although the environment is a more evident aspect than other ones, economic output and potential beneficial to health are discussed further in this description about organic foods. Brazil, has excelled in the growth of this type of farming, however holds the 6th position in the world and 2nd producer in Latin America, with grains and vegetables being the main products, although the livestock reaches the largest area. The consumption of these products is primarily motivated by the perception of organic food as healthier than other kinds of food. However, there are no conclusive studies about better nutritional value, where nutrient concentrations are often unchanged. In contrast the presence of more phytochemicals compounds and reduced pesticides’ content in vegetables, and lipid profile in animal products can justify the health benefits of the products obtained from the organic production system.
Identidad de género y participación política: experiencias de mujeres con liderazgos de base en partidos políticos en Aguascalientes
Authors: Alonso González Claudia
Published: November 2018

En este artículo reflexionaremos, desde la perspectiva de género, acerca de la población que realiza el trabajo de base de los partidos políticos, conformada en su mayoría por mujeres que además de militar en un partido, han desarrollado liderazgos en el ámbito comunitario debido, principalmente, a las actividades de gestión social que realizan. Profundizaremos en las dificultades que enfrenta este sector a lo largo de su participación política. Observaremos que, si bien estas mujeres desarrollan un importante capital social en el ámbito comunitario, éste no logra ser traducido en un capital político que genere mejores oportunidades dentro del partido. Lo anterior proviene no sólo de desventajas de género, sino también de la condición de clase y el nivel de escolaridad. En la segunda parte del artículo haremos un recuento de las transformaciones de la identidad de género que están relacionadas con la actividad política y el desarrollo de estos liderazgos.

Published: November 2018

Este artículo tiene como objetivo identificar las estrategias de aprendizaje que emplean algunos estudiantes universitarios del área educativa. Para tal fin, se realizó un estudio descriptivo a partir de la aplicación del cuestionario de estrategias de aprendizaje de León-Urquijo, Ospian-Marulanda y Ruiz-Lozano (2012, modificado por León-Urquijo, Risco del Valle y Alarcón Salvo, 2014), que mide siete estrategias de aprendizaje: de ensayo, de elaboración, de organización, de metacognición, de autorregulación, de autoevaluación y de apoyo afectivo. El cuestionario se aplicó a 50 estudiantes del Instituto Michoacano de Ciencias de la Educación (IMCED). Los resultados muestran que las estrategias de evaluación y de ensayo son las que tienen más desarrolladas los estudiantes; no obstante, se debe poner más atención en el fortalecimiento de estrategias tales como las de organización, autorregulación, elaboración y las metacognitivas, para que cuenten con las herramientas que les favorezcan un aprendizaje autónomo. Los resultados implican una reflexión acerca de la importancia de cambiar los paradigmas del proceso de enseñanza para reforzar las estrategias que propicien un aprendizaje autónomo, no sólo desde la concientización de las y los docentes, sino desde los modelos educativos y diseños curriculares universitarios.

Study on the Physical and Leakage Current Characteristics of an Optimized High-k/InAlAs MOS Capacitor with a HfO2–Al2O3 Laminated Dielectric
Authors: Guan He , Jiang Chengyu
Published: November 2018

High-k/n-InAlAs MOS capacitors are popular for the isolated gate of InAs/AlSb and InAlAs/InGaAs high-electron mobility transistors. In this study, a new kind of high-k/n-InAlAs MOS-capacitor with a HfO2–Al2O3 laminated dielectric was successfully fabricated using an optimized process. Compared with the traditional HfO2/n-InAlAs MOS capacitor, the new device has a larger equivalent oxide thickness. Two devices, with a HfO2 (8 nm)–Al2O3 (4 nm) laminated dielectric and a HfO2 (4 nm)–Al2O3 (8 nm) laminated dielectric, respectively, were studied in comparison to analyze the effect of the thickness ratios of HfO2 and Al2O3 on the performance of the devices. It was found that the device with a HfO2 (4 nm)–Al2O3 (8 nm) laminated dielectric showed a lower effective density of oxide charges, and an evidently higher conduction band offset, making its leakage current achieve a significantly low value below 10−7 A/cm2 under a bias voltage from −3 to 2 V. It was demonstrated that the HfO2–Al2O3 laminated dielectric with a HfO2 thickness of 4 nm and an Al2O3 thickness of 8 nm improves the performance of the high-k dielectric on InAlAs, which is advantageous for further applications.
Tight Bounds on the Rényi Entropy via Majorization with Applications to Guessing and Compression
Authors: Sason Igal
Published: November 2018

This paper provides tight bounds on the Rényi entropy of a function of a discrete random variable with a finite number of possible values, where the considered function is not one to one. To that end, a tight lower bound on the Rényi entropy of a discrete random variable with a finite support is derived as a function of the size of the support, and the ratio of the maximal to minimal probability masses. This work was inspired by the recently published paper by Cicalese et al., which is focused on the Shannon entropy, and it strengthens and generalizes the results of that paper to Rényi entropies of arbitrary positive orders. In view of these generalized bounds and the works by Arikan and Campbell, non-asymptotic bounds are derived for guessing moments and lossless data compression of discrete memoryless sources.
A Short-Term Decision Model for Electricity Retailers: Electricity Procurement and Time-of-Use Pricing
Authors: Hu Feihu , Feng Xuan , Cao Hui
Published: November 2018

This paper establishes a short-term decision model, based on robust optimization, for an electricity retailer to determine the electricity procurement and electricity retail prices. The electricity procurement process includes purchasing electricity from generation companies and from the spot market. The selling prices of electricity for the customers are based on time-of-use (TOU) pricing which is widely employed in modern electricity market as a demand response program. The objective of the model is to maximize the expected profit of the retailer through optimizing the electricity procurement strategy and electricity pricing scheme. A price elasticity matrix (PEM) is adopted to model the demand response. Also, uncertainty in spot prices is modeled using a robust optimization approach, in which price bounds are considered instead of predicted values. Using a robust optimization approach, the retailer can adjust the level of robustness of its decisions through a robust control parameter. A case study is presented to illustrate the performance of the model. The simulation results demonstrate that the developed model is effective in increasing the expected profit of the retailer and flattening the load profiles of customers.
An Overview of the Portuguese Energy Sector and Perspectives for Power-to-Gas Implementation
Authors: Miguel Carlos V. , Mendes Adélio , Madeira Luís M.
Published: November 2018

Energy policies established in 2005 have made Portugal one of the top renewable power producers in Europe, in relative terms. Indeed, the country energy dependence decreased since 2005, although remaining above EU-19 and EU-28 countries in 2015 (77.4% vs. 62.4% vs. 54.0%, respectively). Data collected from governmental, statistical, and companies’ reports and research articles shows that renewables and natural gas assumed a growing importance in the Portuguese energy mix along time, while oil followed an opposite trend. Recently, the country remarkably achieved a full 70-h period in which the mainland power consumed relied exclusively on renewable electricity and has several moments where power production exceeds demand. Currently, the main option for storing those surpluses relies on pumped hydro storage plants or exportation, while other storage alternatives, like Power-to-Gas (PtG), are not under deep debate, eventually due to a lack of information and awareness. Hence, this work aims to provide an overview of the Portuguese energy sector in the 2005–2015 decade, highlighting the country’s effort towards renewable energy deployment that, together with geographic advantages, upholds PtG as a promising alternative for storing the country’s renewable electricity surpluses.
Nonsteady Shock Wave Attenuation Due to Leakage
Authors: Liu Chenyuan , Liu Huoxing
Published: November 2018

Leakage flow between the rotor and the stator can cause serious performance degradation of wave rotors which utilize nonsteady shock waves to directly transfer energy from burned gases to precompressed air. To solve this problem, primary flow features relevant to leakage are extracted and it was found that the leakage-attributed performance degradation could be abstracted to a special initial-boundary value problem of one-dimensional Euler equations. Then, a general loss assessment method is proposed to solve the problem of nonsteady flow loss prediction. Using the above method, a reasonable physical hypothesis of the initial-boundary value problem depicting the nonsteady leakage flow process is proposed and further, a closed-form leakage loss analytical model combined with an empirical correction method for the discharge coefficient is established. Finally, with the experimentally verified CFD method, comprehensive numerical verification is conducted for the loss prediction model; it is proved that the physical hypothesis of the proposed model in this paper is reasonable and the model is capable of predicting nonsteady shock wave attenuation due to leakage exactly within the range of parameter variations of wave rotors.
Computing Functional Gains for Designing More Energy-Efficient Buildings Using a Model Reduction Framework
Authors: Akhtar Imran , Borggaard Jeff , Burns John
Published: November 2018

We discuss developing efficient reduced-order models (ROM) for designing energy-efficient buildings using computational fluid dynamics (CFD) simulations. This is often the first step in the reduce-then-control technique employed for flow control in various industrial and engineering problems. This approach computes the proper orthogonal decomposition (POD) eigenfunctions from high-fidelity simulations data and then forms a ROM by projecting the Navier-Stokes equations onto these basic functions. In this study, we develop a linear quadratic regulator (LQR) control based on the ROM of flow in a room. We demonstrate these approaches on a one-room model, serving as a basic unit in a building. Furthermore, the ROM is used to compute feedback functional gains. These gains are in fact the spatial representation of the feedback control. Insight of these functional gains can be used for effective placement of sensors in the room. This research can further lead to developing mathematical tools for efficient design, optimization, and control in building management systems.

Published: November 2018

Anderson-Fabry disease (FD) is a rare, progressive, multisystem storage disorder caused by the partial or total deficit of the lysosomal enzyme α-galactosidase A (α-Gal A). It is an X-linked, lysosomal enzymopathy due to mutations in the galactosidase alpha gene (GLA), encoding the α-Gal A. To date, more than 900 mutations in this gene have been described. In our laboratories, the study of genetic and enzymatic alterations related to FD was performed in about 17,000 subjects with a symptomatology referable to this disorder. The accumulation of globotriaosylsphingosine (LysoGb3) was determined in blood of positives. Exonic mutations in the GLA gene were detected in 471 patients (207 Probands and 264 relatives): 71.6% of mutations were associated with the classic phenotype, 19.8% were associated with the late-onset phenotype, and 8.6% of genetic variants were of unknown significance (GVUS). The accumulation of LysoGb3 was found in all male patients with a mutation responsible for classic or late-onset FD. LysoGb3 levels were consistent with the type of mutations and the symptomatology of patients. α-Gal A activity in these patients is absent or dramatically reduced. In recent years, confusion about the pathogenicity of some mutations led to an association between non-causative mutations and FD. Our study shows that the identification of FD patients is possible by associating clinical history, GLA gene analysis, α-Gal A assay, and blood accumulation of LysoGB3. In our experience, LysoGB3 can be considered a reliable marker, which is very useful to confirm the diagnosis of Fabry disease.

Authors: De Angelo Rafaela Molina , Almeida Michell de Oliveira , De Paula Heberth , Honorio Kathia Maria
Published: November 2018

HER-2 and EGFR are biological targets related to the development of cancer and the discovery and/or development of a dual inhibitor could be a good strategy to design an effective drug candidate. In this study, analyses of the chemical properties of a group of substances having affinity for both HER-2 and EGFR were carried out with the aim of understanding the main factors involved in the interaction between these inhibitors and the biological targets. Comparative analysis of molecular interaction fields (CoMFA) and comparative molecular similarity index analysis (CoMSIA) techniques were applied on 63 compounds. From CoMFA analyses, we found for both HER-2 (r2 calibration = 0.98 and q2cv = 0.83) and EGFR (r2 calibration = 0.98 and q2cv = 0.73) good predictive models. Good models for CoMSIA technique have also been found for HER-2 (r2 calibration = 0.92 and q2cv = 0.74) and EGFR (r2 calibration = 0.97 and q2cv = 0.72). The constructed models could indicate some important characteristics for the inhibition of the biological targets. New compounds were proposed as candidates to inhibit both proteins. Therefore, this study may guide future projects for the development of new drug candidates for the treatment of breast cancer.
Use of an Argentine Ant, Linepithema humile, Semiochemical to Deliver an Acute Toxicant
Authors: Gochnour Benjamin M. , Suiter Daniel R. , Davis Jerry W. , Huang Qingguo
Published: November 2018

The Argentine ant, Linepithema humile, is an invasive nuisance, agricultural, and ecological pest from South America. In the United States, its primary distribution is in California and the Southeast. The structural pest control industry responds to property owner complaints when this ant’s populations become problematic and a persistent nuisance. Actions taken to control Argentine ants in the urban and suburban environment are typically complaint-driven, and often involve the application of insecticide sprays applied to the outdoor environment by professional pest managers. In California, and elsewhere, spray treatments of various residual insecticides by property owners and pest management professionals has resulted in significant runoff and in subsequent surface water contamination. As a result, an immediate need exists to develop alternative methods of ant control targeted at reducing environmental contamination. The purpose of this study was to investigate the potential for the development of an alternative method of toxicant delivery focused on the Argentine ant’s behavior modifying cuticular chemistry. In short, methanol and hexane washes of Argentine ant pupae applied to paper dummies were handled significantly more by worker ants than the paper dummies that did not contain the solvent extracts. Additionally, paper wicks soaked in a methylene chloride wash from Argentine ant cadavers, air dried, and then treated with fipronil, were removed by worker ants and placed on a midden pile at the same rate (≈86% to 99% removal at 1 h) as untreated and fipronil-treated ant cadavers. The paper wicks that did not contain the methylene chloride extract were ignored by the worker ants. After three days, the mortality of the ants exposed to the fipronil-treated wicks or the ant cadavers were dose-related. In conclusion, our study suggests that there is potential for the use of ant semiochemicals for the delivery of acute toxicants.

Background: Multilevel anterior cervical decompression and fixation of four and more levels is a common surgical procedure used for several diseases. Methods: We reviewed the radiological and clinical outcomes after anterior cervical discectomy or corpectomy and fixation of four and more levels in 85 patients (55 men and 30 women) with an average age of 59.6 years. Surgical indication was multilevel cervical degenerative myelopathy and radiculopathy in 72 (85%) patients, multilevel cervical spondylodiscitis in four (5%), complex traumatic cervical fractures in four (5%), metastatic cervical spine tumor in two (2%), and ossification of the posterior longitudinal ligament in three (3%) patients. Results: There were no severe intraoperative complications such as spinal cord or vertebral artery injury or dissection. Seventy-three patients had four, 10 patients had five, and two patients had six anterior cervical level fixations. The visual analog scale (VAS) and Japanese Orthopedic Association (mJOA) scale scores improved (6.9 to 1.3 (p < 0.001) and 13.9 to 16.5 (p < 0.001), respectively). The Cobb angle increased from 5.7° to 17.6° postoperatively (p < 0.001). Secondary posterior fixation was necessary in three cases due to pseudarthrosis. Conclusion: The anterior approach appears to be optimal for ventral compressive pathology and lordosis restoration to the cervical spine. Limitations of multiple level decompression and fixation included increasing pseudoarthrosis rates, especially after corpectomy, and increasing fused level numbers.

Gender and Race in Ministry Leadership: Experiences of Black Clergywomen
Authors: Nelms Smarr Kimberly , Disbennett-Lee Rachelle , Cooper Hakim Amy
Published: November 2018

Despite the increase of seminary training, Black clergywomen continuously undergo subjugation, degradation, and humiliation in ministry leadership due to gender and race bias by clergymen. This article reports the findings of a qualitative study that examined the experiences of Black clergywomen regarding obstacles in ministry leadership and how these clergywomen ascribed meaning to their experiences. The two primary research questions were, “What are the experiences of Black clergywomen regarding obstacles in ministry leadership?” and “How do Black clergywomen attribute meaning to their experiences regarding obstacles in ministry leadership?” The results of the study indicated that bias of gender exists among clergymen; however, the Black clergywomen learned to embrace the experiences and learned from them. The conclusion of this article includes a discussion regarding the practical implications of the education of clergymen and clergywomen, and the re-evaluation of the perception of Black clergywomen and their experiences. The purpose of this qualitative study was to explore the experiences of Black clergywomen pertaining to challenges in clergy leadership and to explore how Black clergywomen attributed meaning to their experiences regarding challenges in ministry leadership.
Explorations in Authority in the Daodejing: A Daoist Engagement with Hannah Arendt
Authors: Michael Thomas
Published: November 2018

The present study is an attempt to liberate the thought of the Daodejing from the constraints imposed on it by both traditional Confucian exegesis and modern Western sinological methodologies in the effort to engage the thought of the work more directly. Because the language and thought of the Daodejing are somehow oddly foreign to the Western traditions of analytic philosophy and sinology, this study attempts to make the Daodejing more familiar by recourse to the tradition of continental philosophy, in this case by taking recourse to Hannah Arendt and in particular to her seminal essay on authority. Engaging Arendt’s understanding of authority, this study offers a new look at the thought of the Daodejing by discussing issues that lie at the heart of its political vision, including natural versus political authority, power and coercion, and the relation between authority, tradition, and religion. This study also attempts to situate the fate of the Daodejing’s conception of authority in Chinese political history, and it concludes with a brief look at the contemporary comparative philosophical project that brings the Daodejing into conversation with continental philosophy.
Secularizing Philanthropy in the Twentieth Century: The Pew Family as Trustees of Divine Endowment
Authors: Jungclaus Andrew
Published: November 2018

Planning for the Pew family trusts (founders of Sun Oil) dates to at least 1932 when estate work began for the four Pew children. Fear of inheritance “super-taxes” proposed by Franklin Delano Roosevelt to finance his New Deal was in the air in the 1930s and drove a number of wealthy families to find novel ways to shield their assets from Roosevelt’s various revenue acts. These trusts were meant only to come into effect after the death of each family member, and it was not until 1948 when the four Pews sat down to invest into existence the Pew Memorial Foundation (their father’s posthumous memorial) that they made headlines in terms of secular philanthropy. The Pews saw Roosevelt’s taxes as not only the first blow in a new type of class warfare, but also as a pointed attack against the free market ideologies that allowed individual choice in the ultimate investment of one’s money. This article follows the Pews’ attempts to navigate their responsibilities to family wealth. By examining the logic and theological contours of the Pews’ insistence upon a separation between public and private, profit and loss, and secular market, political lobbying, and religious interest, we learn not only about conservative Protestant influence on American law, but also about the context for the creation of an independent philanthropic “third sector” tied to the evolving role of organized religion in twentieth-century American society.
Model of a Light Extinction Sensor for Assessing Wear Particle Distribution in a Lubricated Oil System

Published: November 2018

Light extinction based optical wear particle counters (OPCs) have been widely used in the industry for oil condition monitoring for several years, and while experiments have tested the benefits and drawbacks of the measurement principle, limited research has been conducted regarding a theoretical approach to evaluate opportunities and limitations of the measurement scheme. In this paper, we present a method for theoretically modelling the output of an OPC based on the light extinction principle in the regime of geometrical optics, with a special focus on the influence of sensor optical design, particle concentration and measurement noise. Moreover, we show that, if only signal amplitude is considered, an algorithm for evaluating sensor output can cause an erroneous assessment of particle contamination level.
2-D Minimum Variance Based Plane Wave Compounding with Generalized Coherence Factor in Ultrafast Ultrasound Imaging
Authors: Qi Yanxing , Wang Yuanyuan , Yu Jinhua , Guo Yi
Published: November 2018

Plane wave compounding (PWC) is an effective modality for ultrafast ultrasound imaging. It can provide higher resolution and better noise reduction than plane wave imaging (PWI). In this paper, a novel beamformer integrating the two-dimensional (2-D) minimum variance (MV) with the generalized coherence factor (GCF) is proposed to maintain the high resolution and contrast along with a high frame rate for PWC. To specify, MV beamforming is adopted in both the transmitting aperture and the receiving one. The subarray technique is therefore upgraded into the sub-matrix division. Then, the output of each submatrix is used to adaptively compute the GCF using a 2-D fast Fourier transform (FFT). After the 2-D MV beamforming and the 2-D GCF weighting, the final output can be obtained. Results of simulations, phantom experiments, and in vivo studies confirm the advantages of the proposed method. Compared with the delay-and-sum (DAS) beamformer, the full width at half maximum (FWHM) is 90% smaller and the contrast ratio (CR) improvement is 154% in simulations. The over-suppression of desired signals, which is a typical drawback of the coherence factor (CF), can be effectively avoided. The robustness against sound velocity errors is also enhanced.

High-rise buildings are susceptible to wind-induced displacements, which can be precisely monitored by using GPS technology. However, GPS monitoring applications may be subject to signal interference and high hardware costs. This study presents a new wind-induced vibration monitoring approach that is based on the mixed use of high-rate and low-rate GPS receivers. In the proposed approach, high-rate receivers are only required in the monitoring stations, where we apply time-differenced positioning to obtain position changes between adjacent epochs. The derived high-rate monitoring station position changes are then integrated with low-rate single epoch relative positioning results between the monitoring and reference stations. Experimental results with both simulated and real data show that the proposed method has a comparable performance with the traditional relative positioning approach, in terms of determining buildings’ vibration frequency, displacement, and acceleration.
