Published: August 2019

Abstract
Due to rapidly increasing pollution, it becomes necessary to substitute fossil fuels, and as wind energy is available quite easily and in abundance, researches are carried out in this area. These facts make it imperative to know about the variables and the problems involved behind it. The wind speed is a random variable, and it depends on atmospheric factors like pressure, relative humidity, wind dispersion & wind direction. This paper introduces the method to effectively predict wind speed by making use of the Levenberg-Marquardt backpropagation algorithm in artificial neural network (ANN) and by conventional means like power law & log law in MATLAB. Data from the Gulf of Khambhat, Gujarat provided by LIDAR for a period of 8 months, was used to prepare valid data set to train the neural network and to build a model to predict wind speed. After obtaining a histogram of the predicted values by log law, power law and ANN, it was seen that wind speed values obtained by ANN were quite close to actual values than the values obtained through the other methods. A comparison in terms of root means square error and percentage of the number of data indicates that developed neural network gives less root mean square error and a higher percentage of data whose absolute error lie between -0.2 and 0.2.

Authors: Liu Y L , Shen J , Sun Y M 
Published: August 2019

Abstract
We have determined the mechanical properties of a long single carbon nanocoil (ALS-CNC) interacting with a focused laser beam. The mechanical oscillation properties of ALS-CNC in liquid based on the interaction of a CNC with light have been demonstrated. Considering the viscous force of a liquid, ALS-CNC oscillation does not occur by laser irradiation when ALS-CNC is in air. A CNC switch controlled by laser irradiation was realized.

Published: August 2019

Abstract
The aim of this study is to find an efficient method for assessment of occupational health and safety management (OHSM) practices which focused on the complexity of the iron and steel industry. Indeed, there are several method used in process management assessment but unfortunately, it does not hold the interaction that can exist between the health and safety risks management process and the complexity of iron and steel industry. To remedy this disadvantage, this study proposed reducing the number of indicators down to several or major KPIs. In order to achieve the selection of small set of KPIs from the larger set of PPIs, a SMART criteria and AHP in the domain of multi-criteria decision making (MCDM) analysis is proposed to be employed for developing a model for the assessment of OHSM practices in Libya iron and steel industry. The enterprises’ safety performance index would benefit from the new assessment model.

Published: August 2019

Abstract
Electrical Discharge Machining (EDM) is a non-contact thermal machining process capable of machining conductive and semi-conductive materials. These capabilities bring to admission of machining materials that characteristically difficult to machine such as Inconel 718 due to its ability to maintain hardness at elevated temperature. Nickel based super alloy, Inconel 718 is one of the difficult to machine material that widely used in such high temperature application. The purpose of the study is to examine the Inconel 718 machinability by applied variable parameters such as peak current, pulse duration and repetitive used of electrode. To obtain the high performance measure in EDM, the selected peak currents were high where it is from 20 to 40A while for pulse duration is from 200 to 4μs. The performance measure that being evaluated are material removal rate (MRR), surface topography and machining accuracy. This research used Copper as electrode due to its high electrical conductivity and achieved highly in MRR. With the series of repetition used of electrode, the carbon layer known as black layer will formed at the surface contact of electrode. The relationship between the parameters and performance measure were more profound through the combination of machining parameters and black layer on the electrode. At high material removal rate, the surface topography of Inconel 718 look rougher with bigger sizes of nodules and craters produced. In the case of machining accuracy, it was found that, overall diameter overcut are less than 3.47%. The result shows that, even applying high peak current and pulse duration, the results of the machining accuracy is still acceptable.
Musculoskeletal symptoms and ergonomic risk assessment among production operators at manufacturing industries: A review
Authors: Segar Ganaswaran , Abdol Rahman Mohd Nasrull 
Published: August 2019

AbstractMusculoskeletal symptoms are prevalent and represent the most common health problem among manufacturing operators in industrial-developing countries, with considerable costs and impact on quality of life. Because of incorrect workstations and lack of employee education in basic biomechanical principles, many of the workers are still in high risk injury. The aim of this study is to understand the impact of ergonomics implementation among production operators as the risk factors of musculoskeletal symptoms. Operators are normally exposed to a variety of risk factors such as awkward and static postures, repeat movement, and powerful effort. Manufacturing operators are thus considered at risk from developing musculoskeletal symptoms (MSSs). This review evaluates selected papers in manufacturing industries that have studied risk factors of musculoskeletal symptoms among manufacturing operators. Furthermore, other related industry studies have been reviewed as applicable. To understand the risk factors of musculoskeletal symptoms among manufacturing operators, it is recommended that future studies be required to assess these risk factors among manufacturing operators.

Published: August 2019

Abstract
Nowadays, product development indicates that a product’s success in the market is determined by the inclusion of consumer’s technical needs for product design. However, implicit feelings and impressions by the consumers is quite challenging because they cannot be externally assessed. Therefore, the makers aim to figure out the factors that contribute to the purchaser’s fulfilments of their product. This paper introduces indicators that can be used to fulfil consumers’ needs specifically to handle the implicit needs of consumers in sustainable product design based on Kansei Engineering (KE) approach. KE is a Japanese design method used to translate feelings into product parameters and was used to look at the car design features of a consumer’s dream car. Preferences of four design features (safety, conveniences, car interaction, and size of capacity) were explored in a sample population of sixty university students through questionnaires. Seven kanseis/feelings elicited by phones were determined to be important to this group: (1) Dynamic, (2) Easy, (3) Elegant, (4) Personality, (5) Positive physical traits, (6) Sophisticated, and (7) Technology. This study chooses to explore the use of Descriptive Statistical and Correlation Component Analysis for statistical significance of the data set as the main method of analysis to determine whether there is a significant difference between the car design features and between the society‘s rating of the car features through Kansei words. Utilizing the system will help another automobile plan that matches consumers’ needs to be proposed.
On the magnetic Hooke-Newton transmutation of electrons
Authors: Lin De-Hone 
Published: August 2019

Abstract
The author investigates the Hooke-Newton transmutation of the electron in the uniform magnetic field. Two results are reported. First, the modulable quantum spectrum and spinor of the magnetic field are given. Spin exhibits its effect, even in the first order approximation of the power series expansion of the spectrum. Since the transmuted Coulomb interaction, attractive or repulsive, is determined by both the signatures of the charge and the total angular momentum, the pure spin states of different orientations experience the reverse Coulomb forces. This feature may be useful in grouping the pure spin states of the same orientation. Second, it is shown that the effect of the effective vector potential due to the geometry of conformal mapping can be generated by the vector potential of two fractional magnetic fluxes with the reverse directions which couple to the different components of the spinor. The equivalence shows the possibility of demonstrating the physics of the 2D electron in conformal space with an isotropic momentum modulation while interacting with the field of the magnetic fluxes.
Efficiency and spectral performance of narrowband organic and perovskite photodetectors: a cross-sectional review
Authors: Pecunia Vincenzo 
Published: August 2019

Abstract
The capability of detecting visible and near infrared light within a narrow wavelength range is in high demand for numerous emerging application areas, including wearable electronics, the Internet of Things, computer vision, artificial vision and biosensing. Organic and perovskite semiconductors possess a set of properties that make them particularly suitable for narrowband photodetection. This has led to rising interest in their use towards such functionality, and has driven remarkable progress in recent years. Through a comparative analysis across an extensive body of literature, this review provides an up-to-date assessment of this rapidly growing research area. The transversal approach adopted here focuses on the identification of: (a) the unifying aspects underlying organic and perovskite narrowband photodetection in the visible and in the near infrared range; and (b) the trends relevant to photoconversion efficiency and spectral width in relation to material, device and processing strategies. A cross-sectional view of organic and perovskite narrowband photodetection is thus delineated, giving fresh insight into the status and prospects of this research area.
Advances in micro cutting tool design and fabrication
Authors: O’Hara John , Fang Fengzhou 
Published: August 2019

Abstract
Microcutting is a precision technology that offers flexible fabrication of microfeatures or complex three-dimensional components with high machining accuracy and superior surface quality. This technology may offer great potential as well as advantageous process capabilities for the machining of hard-to-cut materials, such as tungsten carbide. The geometrical design and dimension of the tool cutting edge is a key factor that determines the size and form accuracy possible in the machined workpiece. Currently, the majority of commercial microtools are scaled-down versions of conventional macrotool designs. This approach does not impart optimal performance due to size effects and associated phenomena. Consequently, in-depth analysis and implementation of microcutting mechanics and fundamentals are required to enable successful industrial adaptation in microtool design and fabrication methods. This paper serves as a review of recent microtool designs, materials, and fabrication methods. Analysis of tool performance is discussed, and new approaches and techniques are examined. Of particular focus is tool wear suppression in the machining of hard materials and associated process parameters, including internal cooling and surface patterning techniques. The review concludes with suggestions for an integrated design and fabrication process chain which can aid industrial microtool manufacture.

Published: August 2019

Abstract

Objective
Bilinguals may be able to retain similar levels of cognitive functioning given age and/or Alzheimer’s Disease-related neurodegeneration, compared to monolinguals. Many studies have yielded equivocal findings that may be explained by within-group differences among bilinguals, such as frequency of language use. The current study aimed to clarify the role of frequency of bilingual language use (i.e., active versus passive) in the association of brain structure and memory. We hypothesized that active bilinguals would demonstrate better memory performance compared to passive bilinguals and monolinguals, and that active bilingualism would buffer the effects of temporal lobe integrity on memory.

Participants and Method
In a longitudinal aging study, 217 older Hispanic adults (Age M = 74 years, SD = 6; 70% women) underwent neuropsychological evaluation and 1.5T MR imaging. Bilingualism was determined by self-reported use of English and Spanish. Active bilinguals reported using both languages daily. Multiple regression tested main effects and interactions of bilingualism and entorhinal cortical thickness on semantic and episodic memory, adjusted for age, sex/gender, and education.

Results
Bilingualism was associated with better semantic memory(F[2,209] = 6.25, p = .002) but not with episodic memory(F[2,209)] = 0.34, p = .71). There was a significant bilingualism X entorhinal cortical thickness interaction on semantic memory (β = -.26, p = .02), indicating that active bilinguals were better able to maintain cognitive functioning with lower cortical thickness, compared to passive bilinguals and monolinguals.

Conclusions
Active bilingualism may protect semantic memory against cortical thinning of the entorhinal cortex. Future studies will explore whether this relationship remains after accounting for additional environmental and sociocultural factors (e.g., immigrant status) that influence the ability or opportunity to become bilingual, and whether active bilingualism affects cognitive trajectory in late life.

Authors: Briceño E , Mehdipanah R , Gonzales X , Langa K , Levine D , Garcia N , Longoria R , Giordani B , Heeringa S , Morgenstern L 
Published: August 2019

Abstract

Objective
Hispanics are a rapidly growing and aging segment of the US population. There is a critical need to accurately and efficiently detect those at risk for dementia, particularly those with Mild Cognitive Impairment (MCI). MCI diagnosis typically relies on neuropsychological tests, although cultural and linguistic factors impact neuropsychological test scores. The current study reviews neuropsychological studies on MCI in Hispanics to evaluate the factors in testing for MCI diagnosis.

Participants and Method
Studies were identified from a literature search utilizing Web of Science, PubMed, Google Scholar, and Scopus, using search terms “Hispanic OR Mexican American” and “Mild Cognitive Impairment,” and from the reference sections of studies identified through this search. Studies utilizing neuropsychological tests in the diagnosis of MCI for Hispanics living in the US were identified and reviewed. Approaches for sample characterization (e.g., country of origin and of education, literacy, language preference and proficiency), neuropsychological test methods (e.g., test selection and translation, normative data source), and method of MCI diagnosis were reviewed.

Results
Considerable variability was found across studies with regard to the incorporation – and the method of incorporation – of cultural factors and their consideration in the MCI diagnosis process for Hispanics. For example, several studies did not report their sample’s country of education, source of normative data used for determination of cognitive impairment, or method of test adaptation/translation.

Conclusions
Diagnosis of MCI in Hispanics has been complicated by a dearth of culturally appropriate neuropsychological assessment tools and normative data, which likely contributes to inconsistency across studies. Future studies are needed to further develop culturally appropriate neuropsychological methods to evaluate MCI in Hispanics in the US and to improve diagnostic accuracy in this population.
Health Literacy is Linked to Executive Functioning in Older American Indians
Authors: Burks A , Avila J , Kaz G , Pacheco S , Verney S 
Published: August 2019

Abstract

Objective
Health literacy (HL), the ability to understand one’s own medical conditions and navigate the healthcare system, is strongly associated with both educational achievement and executive functioning. Many American Indians (AIs) have experienced trauma in early education, such as forced removal into harsh boarding school systems; these experiences may impact their educational achievement, and subsequently, HL. Further, AIs disproportionately experience a myriad of chronic diseases. The goal of this study is to investigate the relationship between HL and executive functioning in older AIs.

Participants and Method
Participants were recruited from a southwestern urban area, who self-identified as AIs, aged 55 to 80 (n = 43). Participants were asked to complete a series of questionnaires, interviews, and neuropsychological tests over two sessions, the second session was optional. This poster investigates the data from participants who completed both sessions. We created a composite variable of HL measures, (Rapid Estimate of Adult Literacy in Medicine, Newest Vital Sign, and the Short Test of Functional Health Literacy in Adults verbal and numeracy z-scores).

Results
HL was positively correlated with both WASI Matrix Reasoning and WASI Similarities. Similarly, HL was positively correlated with Verbal Semantic Fluency (VSF) – Animals and Plants. However, there was no significant correlation between HL and VSF – Fruits and Vegetables or HL and Trails Making – B.

Conclusions
These findings suggest that HL and executive functioning are linked in older AIs. Discrepancies between the executive functioning tests (VSF – Animals, Fruits/Vegetables, and Plants) may be due to resources, culture, and education quality. These findings highlight the need for further investigation of cultural context and the accompanying development of culturally appropriate measures.
Drug use and Visual-Motor Integration in a Sample of Hispanic Women
Authors: Diaz B 
Published: August 2019

Abstract

Objective
The use of illicit drugs has increased dramatically over the past two decades among Hispanics. Neurocognitive impairments and morphological alterations have been linked to the use of drugs among the Hispanic population. However, even when increased attention is paid to the impact of drug consumption on neurocognitive functions among Hispanics, the majority of publications have been limited to male samples. This is relatively important, considering that women who consume illicit drugs appear to be more vulnerable in developing drug dependence and exhibit more neurocognitive impairment when compared to men. The present study aims to determine the impact of drug consumption in the visual-motor integration in a sample of Puerto Rican women. Our hypothesis was that Puerto Rican women who consume illicit drugs would perform poorly on visual-motor integration when compared to non-consumers.

Participants and Method
A total of 59 Puerto Rican women participated in this cross-sectional study. The participants were divided into three groups according to the criteria of: consumers, non-consumers, and abstinence. To evaluate the visual-motor integration, we administered the neuropsychological Bender-Gestalt-II test to all participants.

Results
A Kruskal-Wallis analysis revealed that there was a statically significant difference in the visual-motor integration between groups (H(2) = 12.69, p = 0.02), with a mean rank of 28 for consumers, 40 for non-consumers, and 21 for abstinence group. However, there was no significant difference between the abstinence and consumer groups in their visual-motor integration (p = .217).

Conclusions
These results suggest that the use of drugs can impact some neurocognitive functions, such as visual-motor integration in women, and can lead to a decline in such functions- even after sustained abstinence.
Updated Demographically Adjusted Norms for the Brief Visuospatial Memory Test-Revised and Hopkins Verbal Learning Test-Revised in Monolingual Spanish Speakers from the United States – Mexico Border Region

Published: August 2019

Abstract

Objective
Culturally and linguistically appropriate neuropsychological assessments for the large number of primary Spanish speakers in the United States remain imperative to serve the needs of this underserved population. As part of a larger co-norming project, we generated demographically adjusted norms for the Brief Visuospatial Memory Test-revised (BVMT-R) and the Hopkins Verbal Learning Test-revised (HVLT-R) for use with native Spanish speakers from the U.S.-Mexico border regions.

Participants and Method
Participants were 202 healthy native Spanish speakers recruited in San Diego, CA and Tucson, AZ, ages 19 to 60, with education ranging from 0-20 years, and 59% women. Test stimuli for the HVLT-R and instructions for both tests were adapted into Spanish by a team of native Spanish speakers from multiple countries using standard procedures (Cherner et al., 2007). Raw scores for the various learning and delayed recall outcomes were converted to T-scores using fractional polynomial equations accounting for effects of education, age, and sex. We then computed the rates of impairment that would be obtained when applying the original published norms for these two tests, and compared these results to the expected rate of impairment of -1SD (around 16%) derived from the normal distribution of T-scores in our new, demographically corrected norms.

Results
Results showed significant overestimation of impairment when applying the original norms for non-Hispanic English speakers to our Spanish-speaking sample, ranging from 35-38% for HVLT-R and 25-26% for BVMTR. As expected, these overestimations of impairment were greater for individuals with lower education, but our demographically corrected norms reduced the rate of impairment for all levels of education.

Conclusions
These findings highlight the urgent need to account for demographic effects on neuropsychological performance in order to improve the diagnostic accuracy of our measures when applied to US-dwelling Spanish speakers.
