Fault diagnosis of rotating machinery using wavelet-based feature extraction and support vector machine classifier
Authors: Tran Han , Noori Mohammad , Altabey Wael A. , Wu Xi
Published: July 2017

Modern machine tools with high speed machining capabilities could place rotating shafts, gears, and bearings under extreme thermal, static, and impact stresses, potentially increasing their failure rates. In this research, a gearbox damage detection strategy based on discrete wavelet transform (DWT), wavelet packet transform (WPT), support vector machine (SVM), and artificial neural networks (ANN) is presented. Three case studies are conducted to compare the classification performance of SVM kernel functions and ANN. First, a fault detection analysis based on DWT and WPT is carried out to extract the damage information from the gearbox’s raw vibration signal. In this step, wavelet coefficients obtained from DWT are characterized using statistical calculations. Energy characteristics of the gearbox signal are acquired using WPT and their statistical characteristics are also computed. These three sets of information extracted from wavelet transforms are utilized as the input to SVM and ANN classifiers. Secondly, the improved distance evaluation technique (IDE) is implemented to select the sensitive input features for SVM and ANN. The penalty parameter C and kernel parameter γ in SVM are also optimized using the grid-search method. Finally, the optimized features and parameters are input into SVM and ANN algorithms to detect gearbox damage. The result shows that gearbox damage detection using energy characteristics extracted from WPT (Case 2) or their statistical values as input features (Case 3) to the learning algorithms produces higher classification accuracies than using statistical values of the DWT coefficients as inputs (Case 1). In addition, RBF-SVM has the best classification performance in Case 2 and 3 while Linear-SVM has the best classification accuracy rate in Case 1 in damage detection average.

Hybridization of Genetic and Group Search Optimization Algorithm for Deadline-Constrained Task Scheduling Approach
Authors: Taj Nazneen , Basu Anirban
Published: July 2017

Cloud computing is an emerging technology in distributed computing, which facilitates pay per model as per user demand and requirement. Cloud consists of a collection of virtual machines (VMs), which includes both computational and storage facility. In this paper, a task scheduling scheme on diverse computing systems using a hybridization of genetic and group search optimization (GGSO) algorithm is proposed. The basic idea of our approach is to exploit the advantages of both genetic algorithm (GA) and group search optimization algorithms (GSO) while avoiding their drawbacks. In GGSO, each dimension of a solution symbolizes a task, and a solution, as a whole, signifies all task priorities. The important issue is how to assign user tasks to maximize the income of infrastructure as a service (Iaas) provider while promising quality of service (QoS). The generated solution is competent to assure user-level (QoS) and improve Iaas providers’ credibility and economic benefit. The GGSO method also designs the producer, scrounger ranger, crossover operator, and suitable fitness function of the corresponding task. According to the evolved results, it has been found that our algorithm always outperforms the traditional algorithms.
“Subject-predicate predicate sentences” in modern Mandarin Chinese: A Cardiff Grammar approach
Authors: He Wei
Published: July 2017

This study investigates “subject-predicate predicate sentences” (“S-P P sentences”) in modern Mandarin Chinese from a Cardiff Grammar approach with the aim of answering three main questions: (i) What is/are the functional syntactic structure(s) of the sentences to be considered in the study? (ii) What is/are the semantic motivation(s) for the structure(s)? (iii) What is/are the contextual constraints on the structure(s)? The study is guided by three basic principles: (a) language is multifunctional; (b) meaning is primary while form is the realization of meaning; and (c) different strands of meaning are realized by a single syntactic structure. Further, the study utilizes the concepts of Theme and Subject within the Cardiff Grammar in order to analyze and discuss the generally acknowledged seven types of “S-P P sentences”. The results show that only one type is truly S-P P and another type only in one sense, whereas no other types can be categorized as such. All the syntactic structures are conditioned by a different set of distinctive semantic features and contextual factors.

Authors: Liang Bau-Jy , Liu Don-Gey , Yeh Chia-Hung , Chen Hsiao-Chun , Fang Yu-Chen , Hung Pi-Fang
Published: July 2017

In this paper, an accurate 3-dimensional (3-D) analytical solution is proposed to calculate the projective capacitances of touch panels. In this study, both simple and complex patterns were investigated for the calculation. We propose a partition strategy to divide a pattern into many rectangular or triangular sub-patterns. Each sub-pattern can be further cut into 2-D slices. The capacitance of a 2-D slice was then solved by our closed-form formulae. The total capacitance of a pattern was obtained by integrating up all the partial capacitances of the slices. In this study, the precision of our analytical method was examined by comparing the simulation results obtained from Q3D

Published: July 2017

It has been proven that quantum adders are forbidden by the laws of quantum mechanics. We analyze theoretical proposals for the implementation of approximate quantum adders and optimize them by means of genetic algorithms, improving previous protocols in terms of efficiency and fidelity. Furthermore, we experimentally realize a suitable approximate quantum adder with the cloud quantum computing facilities provided by IBM Quantum Experience. The development of approximate quantum adders enhances the toolbox of quantum information protocols, paving the way for novel applications in quantum technologies.
Comparing the performance of linear and nonlinear principal components in the context of high-dimensional genomic data integration
Authors: Islam Shofiqul , Anand Sonia , Hamid Jemila , Thabane Lehana , Beyene Joseph
Published: July 2017

Linear principal component analysis (PCA) is a widely used approach to reduce the dimension of gene or miRNA expression data sets. This method relies on the linearity assumption, which often fails to capture the patterns and relationships inherent in the data. Thus, a nonlinear approach such as kernel PCA might be optimal. We develop a copula-based simulation algorithm that takes into account the degree of dependence and nonlinearity observed in these data sets. Using this algorithm, we conduct an extensive simulation to compare the performance of linear and kernel principal component analysis methods towards data integration and death classification. We also compare these methods using a real data set with gene and miRNA expression of lung cancer patients. First few kernel principal components show poor performance compared to the linear principal components in this occasion. Reducing dimensions using linear PCA and a logistic regression model for classification seems to be adequate for this purpose. Integrating information from multiple data sets using either of these two approaches leads to an improved classification accuracy for the outcome.

Residual Symmetry Analysis for Novel Localized Excitations of a (2+1)-Dimensional General Korteweg-de Vries System
Authors: Zhu Quanyong , Fei Jinxi , Ma Zhengyi
Published: July 2017

The nonlocal residual symmetry of a (2+1)-dimensional general Korteweg-de Vries (GKdV) system is derived by the truncated Painlevé analysis. The nonlocal residual symmetry is then localized to a Lie point symmetry by introducing auxiliary-dependent variables. By using Lie’s first theorem, the finite transformation is obtained for the localized residual symmetry. Furthermore, multiple Bäcklund transformations are also obtained from the Lie point symmetry approach via the localization of the linear superpositions of multiple residual symmetries. As a result, various localized structures, such as dromion lattice, multiple-soliton solutions, and interaction solutions can be obtained through it; and these localized structures are illustrated by graphs.
Aggravating and Mitigating Factors in Context
Authors: Cheng Kevin Kwok-yin
Published: July 2017

Despite the significant role that aggravating and mitigating factors play in sentencing outcomes, they have been neglected by both policy and research. The purpose of this study is to examine the influence of culture—which has been deemed to be an “elusive” influence—in the plea mitigation and sentencing process. An empirical study was conducted to examine the effects of both offense-specific and offender-specific factors that may serve to aggravate or mitigate the sentence in a magistrate’s court in Hong Kong. Data was collected through courtroom observations of sentencing hearings (n = 712). Statistical analyses reveal that Chinese cultural and social norms motivate judicial decisions, as defendants who did not conform to the cultural expectations of family, industry, enduring hardships, and maintaining good social order are likely to be sentenced more severely when they are convicted of a crime. A disciplinary model of sentencing is proposed to explain why certain factors are considered as aggravating in Hong Kong’s penal culture. These factors, however, are extraneous to the offense or the culpability of the offender. Implications and future directions are discussed.

Published: July 2017

Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

Regulated intracellular proteostasis, controlled in part by proteolysis, is essential in maintaining the integrity of podocytes and the glomerular filtration barrier of the kidney. We applied a novel proteomics technology that enables proteome-wide identification, mapping, and quantification of protein N-termini to comprehensively characterize cleaved podocyte proteins in the glomerulus in vivo. We found evidence that defined proteolytic cleavage results in various proteoforms of important podocyte proteins, including those of podocin, nephrin, neph1, α-actinin-4, and vimentin. Quantitative mapping of N-termini demonstrated perturbation of protease action during podocyte injury in vitro, including diminished proteolysis of α-actinin-4. Differentially regulated protease substrates comprised cytoskeletal proteins as well as intermediate filaments. Determination of preferential protease motifs during podocyte damage indicated activation of caspase proteases and inhibition of arginine-specific proteases. Several proteolytic processes were clearly site-specific, were conserved across species, and could be confirmed by differential migration behavior of protein fragments in gel electrophoresis. Some of the proteolytic changes discovered in vitro also occurred in two in vivo models of podocyte damage (WT1 heterozygous knockout mice and puromycin aminonucleoside–treated rats). Thus, we provide direct and systems-level evidence that the slit diaphragm and podocyte cytoskeleton are regulated targets of proteolytic modification, which is altered upon podocyte damage.

Authors: D. Muthulakshmi , R. Sasirekha , R. Medha
Published: July 2017

Background: This study was undertaken to study the association of serum β hCG levels between 12 to 20 weeks of gestation and development of hypertensive disorders of pregnancy and to assess the association between the levels of β hCG and severity of hypertensive disorders of pregnancy. Study design: Prospective cohort study (200 uncomplicated primigravida).Methods: All women between 12 to 20 weeks of pregnancy meeting the selection criteria, attended antenatal OPD in JIPMER were recruited for this study after informed consent. The venous blood samples were obtained from the subjects for β-hCG analysis. Serum β hCG level was measured by Enzyme Linked Immunoassay System (ELISA) and expressed as mIU/ml. Multiples of median were calculated from the median of the sample population and were considered as raised if it was >2 MOM. The cases were followed up until delivery and observed for development of hypertensive disorders of pregnancy.Results: Out of 200 cases, 185 cases were followed completely till term. Among 185 cases who were followed up, 10 women developed hypertensive disorders of pregnancy, accounting for 5.4% in the study group. Out of the total 185 women who were studied, 132 had β hCG levels ≤2 MOM and 53 had β hCG levels >2 MOM. Among 132 women (94.7%) with β hCG levels ≤2 MOM, 7 (5.3%) developed hypertensive disorders. Among 53 cases (94.3%) with β hCG levels >2 MOM, 3 women (5.7%) developed hypertensive disorders. The incidence of HDP was almost similar in both the groups, 5.3% among those whose β hCG levels were ≤2MOM and 5.7% among those who had β hCG levels >2 MOM (p value - 0.923).Conclusions: From the present study, it may be concluded that high serum β hCG levels (2 MOM) estimated between 12 to 20 weeks of pregnancy were not predictive of development of hypertensive disorders later in pregnancy.

Published: July 2017

Background: Cardiovascular disease has emerged as the single most important cause of death worldwide. Every patient of MI has to be stratified according to the risk factors, so that high risk patients can be identified and can be managed effectively GRACE risk score is one of the score used to calculate the risk in MI. Present study was undertaken to correlate GRACE risk score and mortality in non-STEMI.Methods: 200 patients of non-STEMI fulfilling the inclusion criteria admitted in wards of NMCH, Kota were recruited. GRACE risk score was calculated for all patients. Each patient monitored closely throughout their hospitalization. Each component of GRACE risk score was studied for statistical significance. Statistical analysis of correlation was done with chi square test and statistical significance was taken p < 0.05.Results: Mean age is 59.45±8.66 years, with male preponderance, male to female ratio 3:1. Maximum GRACE score is 300 and the minimum score is 86. Patients were categorized into low (74 patients), intermediate (60 patients), high risk (66 patients) according to GRACE score. 14 patients were expired and all of them are in high risk category. GRACE score had sensitivity (100%), specificity (72.04%), positive predictive value (21.2%) and negative predictive value (100%). Serum creatinine (p<0.001), heart rate (p<0.001), blood pressure (p<0.001), Killip class (p<0.001), cardiac biomarkers (p<0.001), ST segment changes (p<0.001) were significantly associated with adverse events. Age>50 (p<0.110) is not significant. Overall grace score demonstrated excellent discrimination (p<0.001), C statistics 0.99, 95% CI 115.742-151.221 for in hospital mortality.Conclusions: This study has shown GRACE risk score is highly accurate in predicting in hospital mortality in patients of non-STEMI. We should routinely use GRACE risk score in our hospital settings to identify the high-risk patients to decrease mortality.

Authors: Mittal Mahim , Singh Pavan Kumar , Kurian Sonu
Published: July 2017

Background: Peripheral neuropathy is not an uncommon complication of liver cirrhosis but it is not given much clinical relevance. The pattern and prevalence of peripheral neuropathy has also not been studied extensively. Alcohol use, coexisting diseases and nutritional deficiency have been postulated as factors responsible for neuropathy. The aim of this study was to define the pattern and prevalence of neuropathy in cirrhosis and to determine any etiologic correlation.Methods: 85 patients of cirrhosis of liver were studied. Apart from routine investigations, serum vitamin B12 estimation was also done in these patients. Electrophysiological studies were done in 46 patients.Results: Alcohol was the most common etiology of cirrhosis (57.6%). Hepatitis B related (11.8%) and Hepatitis C (4.7%) were other etiologies. The prevalence of peripheral neuropathy by electrophysiological studies was found to be 67.39% in cirrhosis of any etiology, of which 43.5% had sensorimotor type and the predominant pattern of peripheral neuropathy was mixed axonal degeneration and demyelination. The peripheral neuropathy was significantly more (p=0.01) in child class C than other child classes. Prevalence of neuropathy had no significant difference (p=1.00) between alcoholic and non-alcoholic cirrhosis. No correlation was present with either serum vitamin B12 levels or blood glucose levels.Conclusions: Peripheral neuropathy is present in more than half of cirrhosis patients and is unrelated to etiology and nutritional status but related to the severity of cirrhosis.

Background: The metabolic syndrome is a deadly combination of hypertension, diabetes, heart disease, and dyslipidemia due to abdominal obesity. The causes this is both bad genes and bad environment. The objective of this study was to assess the efficacy of metabolic control of diabetes in the development of neuropathy.Methods: The present hospital based cross sectional study was conducted at MNR Medical College and Hospital, Sangareddy. The study was undertaken between October 2012 to May 2014 both in inpatient and outpatient department. Diabetic patients seeking consultation for the symptoms suggestive of neuropathy were screened and labeled as suffering from diabetic neuropathy based on the inclusion and exclusion criteria.Results: Diabetic neuropathy was common in the age group of 56 to 65 years in both male and female (33.3%). Average duration of diabetes was 8.7 years. Overall the rate of irregularity was much more (78%). Maximum (78%) patients reported presence of sensory symptoms. Diminision or loss of both ankle jerks was present in all 60 cases while 28 patients showed sluggish or absent knee jerks in total 60 patients. Maximum patients (60%) had distal symmetrical neuropathy.Conclusions: Longstanding diabetes and poor glycaemic control are particularly associated with an increased risk of neuropathy in diabetes mellitus.

Published: July 2017

The article specifies formulas of reducing environmental performance and combustion characteristics of a gas turbine engine, as well as its thermodynamic parameters to the standard atmospheric conditions, with flight altitude H = 0 and Mach number M = 0: p0= 760 mm Hg. (101.325 kPa), T0=288.15 K (+15C), for which the engine technical assignment is specified. The atmospheric conditions determined by the air temperature, pressure and humidity vary over a wide range depending on the season, terrain elevation, and latitude. Therefore, reduction of engine characteristics to the standard atmospheric conditions is necessary and it is based on the similarity theory, i.e. on maintaining constant gas dynamic and geometrical criteria of the combustion chamber. An integral mathematical model of the combustion chamber forms the theoretical basis of the presented reduction method. It is grounded on the results of solving a system of differential equations describing heat, mass (concentration) and momentum transfer specified by the combustion chamber theory. The article shows a significant influence of the ambient air temperature on emission and fuel combustion characteristics as distinct from the influence of other atmospheric parameters.

Mathematical modeling of a controlled electromechanical actuator for special assembly and coupling equipment
Authors: Nosov A. S.
Published: July 2017

The article presents theoretical and experimental bases for the creation of a driving gear with an actuating mechanism based on a planetary roller drive to improve the fidelity of the specified motion law and velocity performance of the support equipment actuators and engineering systems of missile and space-rocket complexes, as well as for integrated tests of heavy missiles. We present a mathematical model of a controlled electromechanical actuator for special assembly and coupling equipment. The results of the tests carried out lead to the conclusion that in order to create a high precision electromechanical drive, it is necessary to use transmission with a smaller gap between the mating elements, high accuracy and reliability of operation. A new design of a planetary roller drive and the advantages of using a stepper motor are described. Thus, mathematical modeling of an electromechanical actuator with a planetary roller drive with a mockup test on an assembly and coupling tilting device makes it possible to create an electromechanical actuator with improved technical and operational characteristics for a tilting device of the space head of a super heavy launch vehicle. This reduces the probability of emergency situations during conducting government and commercial space programs.

Published: July 2017

The operation of Front-Office of a hotel or a holiday centre is dependent on the effectiveness and efficiency of services rendered. When hotel services are predominantly manual, timely services may not be witnessed at all. But with the deployment of ICTs in front-office department of hotels services are rendered speedily and first impression of efficient service are created in the mind of the guest. This paper x-rayed the operational impact of deployment in front-office of selected hotels in South-east and South-South zone of Nigeria. The paper took an empirical study of selected hotels in the two zones, using a primary data collection technique via questionnaire to ascertain the level of deployment of ICTs in hotels and its operational effects in the service-delivery of concerned hotels. The result showed a concordance of the positive contribution of ICT in front-office with a Regression coefficient (R) of 0.841 (84.1%) coefficient of determination and the stated null hypotheses were rejected with sig. value of 0.000 alpha of 95% confidence interval. Therefore, it can be concluded that ICT is a positive contributor to efficiency in hotels and hospitality industries should encourage its installation and deployment
Community Partners in Care: 6-Month Outcomes of Two Quality Improvement Depression Care Interventions in Male Participants
Authors: Mehta Pratik , Brown Anthony , Chung Bowen , Jones Felica , Tang Lingqi , Gilmore James , Miranda Jeanne , Wells Kenneth
Published: July 2017

Objective: Limited data exist on approaches to improve depression services for men in under-resourced communities. This article explores this issue using a sub-analysis of male participants in Community Partners in Care (CPIC). 

Design: Community partnered, cluster, randomized trial. 

Setting: Hollywood-Metropolitan and South Los Angeles, California. 

Participants: 423 adult male clients with modified depression (PHQ-8 score≥10). 

Interventions: Depression collaborative care implementation using community engagement and planning (CEP) across programs compared with the more-traditional individual program, technical assistance (Resources for Services, RS). 

Main Outcomes Measured: Depressive symptoms (PHQ-8 score), mental health-related quality of life (MHRQL), mental wellness, services utilization and settings. 

Results: At screening, levels of probable depression were moderate to high (17.5%- 47.1%) among men across services sectors. Intervention effects on primary outcomes (PHQ-8 score and MHRQL) did not differ. Men in CEP compared with RS had improved mental wellness (OR 1.85, 95% CI 1.00–3.42) and reduced hospitalizations (OR .40, 95% CI .16–.98), with fewer mental health specialty medication visits (IRR 0.33, 95% CI .15–.69), and a trend toward greater faith-based depression visits (IRR 2.89, 95% CI .99–8.45). 

Conclusions: Exploratory sub-analyses suggest that high rates of mainly minority men in under-resourced communities have high prevalence of depression. A multisector coalition approach may hold promise for improving community-prioritized outcomes, such as mental wellness and reduced hospitalizations for men, meriting further development of this approach for future research and program design.

Published: July 2017

Purpose: Systemic inflammation, measured by C-reactive protein (CRP), is an important risk factor for cardiovascular disease (CVD) and mortality. We investigated whether aerobic exercise training (AEXT) affects African Americans with high inflammation (HI) the same way it does African Americans with low inflammation (LI) in terms of CVD risk factors. 

Methods: 23 African Americans with CRP levels <3 mg/L (LI) and 14 African Americans with CRP ≥3 mg/L (HI) underwent six months of AEXT. Participants were sedentary, non-diabetic, non-smoking, with clinical blood pressure <160/100 mm Hg, were non-hyperlipidemic, had no signs of cardiovascular, renal, or pulmonary disease, and were not on medication. Measures included CD62E+ endothelial microparticles (EMPs), a measure of early stage endothelial dysfunction, as well as lipid and glucose profile, aerobic fitness, body composition, and blood pressure. 

Results: The LI group improved aerobic fitness by 10%, body mass index by 3%, and plasma triglycerides by 20%, with no change being observed in HI group for these variables. The HI group improved fasting plasma glucose levels by 10%, with no change occurring in the LI group. Both groups improved CD62E+ EMPs by 38% and 59% for the LI and HI group, respectively. 

Conclusions: A standard AEXT intervention differentially affected CVD risk factors among African Americans with high and low inflammation. This may indicate that, in African Americans with high inflammation, AEXT alone may not be enough to reap the same benefits as their low-inflammation peers in terms of CVD risk modification.

Objective: To report baseline character­istics of junior-level faculty participants in the Summer Institute Programs to Increase Diversity (SIPID) and the Programs to In­crease Diversity among individuals engaged in Health-Related Research (PRIDE), which aim to facilitate participants’ career devel­opment as independent investigators in heart, lung, blood, and sleep research.

Design and Setting: Junior faculty from groups underrepresented in the biomedical-research workforce attended two, 2-3 week, annual summer research-education programs at one of six sites. Programs provided didactic and/or laboratory courses, workshops to develop research, writing and career-development skills, as well as a mentoring component, with regular contact maintained via phone, email and webinar conferences. Between summer institutes, trainees participated in a short mid-year meeting and an annual scientific meeting. Participants were surveyed during and after SIPID/PRIDE to evaluate program compo­nents.

Participants: Junior faculty from under­represented populations across the United States and Puerto Rico participated in one of three SIPID (2007-2010) or six PRIDE programs (2011-2014).

Results: Of 204 SIPID/PRIDE participants, 68% were female; 67% African American and 27% Hispanic/Latino; at enrollment, 75% were assistant professors and 15% instructors, with most (96%) on non-tenure track. Fifty-eight percent had research doctorates (PhD, ScD) and 42% had medi­cal (MD, DO) degrees. Mentees’ feedback about the program indicated skills develop­ment (eg, manuscript and grant writing), access to networking, and mentoring were the most beneficial elements of SIPID and PRIDE programs. Grant awards shifted from primarily mentored research mechanisms to primarily independent investigator awards after training.

Published: July 2017

Radar altimetry provides valuable measurements to characterize the state and the evolution of the Antartica and Greenland ice sheet cover. Global Navigation Satellite System Reflectometry (GNSS-R) has the potential capacity of complementing the dedicated radar altimeters incrementing the temporal and spatial resolution of the surface height measurements. In this work we perform an study of the Greenland ice sheet using data obtained by the GNSS-R instrument aboard the British TechDemoSat-1 (TDS-1) satellite mission, designed primarily to provide sea state information, like sea surface roughness or wind, but not altimetric products. The data has been analyzed with altimetric methodologies, already proved in aircraft based experiments, to extract signal delay observables to be used to infer the topography of the Greenland cover. The penetration depth of the GNSS signals into ice has also considered. The topographic signal obtained is consistent with those obtained with other passive or active microwave sensors. The main conclusion derived from this work is that GNSS-R also provides valuable measurements of the ice sheet cover and, as taken at a variety of geometries and at least two frequency bands, they prospect different depths into the ice. They have thus potential to complement our understanding of the ice firn and its evolution.

Though Cyber Physical Systems (CPS) become very popular in last the decade, dependability of CPS is still a critical issue and related survey is rare. We try to spell out the jigsaw of technologies and figure out the technical trends of dependable self-managing CPS. This survey first recalls the motivation and the similar concepts. By analyzing four generic architectures, we summarize the common characteristics and related assurance technologies, and propose a more generic environment-in-loop processing flow of CPS and a formal interaction flow between physical space and cyber space. Further, the similarity between correctness and dependability is formally analyzed and the new five research questions of dependable self-managing CPS are presented. Then we review the critical technologies and related correctness verification & validation (V&V) methods, the architectures for dependable self-managing CPS. Further, the detail dependability management and V&V technologies are surveyed, which covers the areas of running-time fault management methods and whole life cycle V&V technologies, maintenance and available tool sets. For holistic CPS development, Modeling techniques and MDE (model driven engineering) based V&V methods are analyzed in detail. Then we complete the jigsaw of technologies and figure out the missing part. Further, we propose the technical challenges and the further direction. To our best knowledge, this is the first comprehensive survey on dependable self-managing CPS development and evaluation.
The Class of (p,q)-spherical Distributions
Authors: Richter Wolf-Dieter
Published: July 2017

For evaluating probabilities of arbitrary random events with respect to a given multivariate probability distribution, specific techniques are of great interest. An important two-dimensional high risk limit law is the Gauss-exponential distribution whose probabilities can be dealt with based upon the Gauss-Laplace law. The latter will be considered here as an element of the newly introduced family of (p,q)-spherical distributions. Based upon a suitably defined non-Euclidean arc-length measure on (p,q)-circles we prove geometric and stochastic representations of these distributions and correspondingly distributed random vectors, respectively. These representations allow dealing with the new probability measures similarly like with elliptically contoured distributions and more general homogeneous star-shaped ones. This is demonstrated at hand of a generalization of the Box-Muller simulation method. En passant, we prove an extension of the sector and circle number functions.

Published: July 2017

Objectives. To determine whether 2012 to 2015 (times 1–3) ridership changes correlated with body mass index (BMI) changes after transit line completion in Salt Lake City, Utah.

Methods. We used Global Positioning System/accelerometry–measured transit ridership measures in 2012 to 2013 (times 1–2) to compare objective and self-reported ridership. Regression models related changes in objectively measured ridership (times 1–2) and self-reported ridership (times 1–2 and times 1–3) to BMI changes, adjusting for control variables.

Results. Objective and self-reported ridership measures were consistent. From time 1 to 2 (P = .021) or to 3 (P = .015), BMI increased among self-reported former riders and decreased among new riders (P = .09 for both times 1–2 and times 1–3), although the latter was nonsignificant. Time 3 attrition adjustment had no effect on results. Adjusting for baseline BMI, the nonsignificant effect for new riders remained nonsignificant, indicating no BMI change; the BMI increase after discontinuing transit remained significant.

Conclusions. Observed BMI increases subsequent to stopping transit ridership persisted for more than 2 years (postintervention). These results suggest that transit ridership protects against BMI gains and support the need to provide convenient transit for public health.
Kinematic Characteristics of an Osteotomy of the Proximal Aspect of the Fibula During Walking
Authors: Huang Wenhan , Lin Zefeng , Zeng Xiaolong , Ma Limin , Chen Lingling , Xia Hong , Zhang Yu
Published: July 2017

Case:

A 51-year-old patient with medial compartment osteoarthritis of the left knee underwent an osteotomy of the proximal aspect of the fibula. Gait kinematic data were collected before and after the surgery with use of an optical tracking system during level walking. A sharp increase of approximately 5° to 7° in femoral abduction and a 5° to 8° increase in femoral external rotation were exhibited at 3 months postsurgery. At 1 year postsurgery, femoral external rotation had increased by 3° to 5°. There was also an increase of distal femoral translation (approximately 2 to 10 mm).

Conclusion:

An osteotomy of the proximal aspect of the fibula altered the kinematics by increasing valgus, femoral external rotation, and distal translation of the knee. These alterations may help reduce knee pain and improve early functional recovery.

Published: July 2017

Takanari, an indica cultivar of rice (Oryza sativa L.), is one of the Japanese cultivars with the highest yield. Although previous studies have indicated that Takanari has a greater photosynthetic capacity in canopy top leaves, which is achieved partly by its higher nitrogen (N) content per leaf area, N distribution at the whole‐canopy level has not been studied. We addressed following questions: (i) Does Takanari have a higher N uptake rate? (ii) Does Takanari have more leaf N in the whole canopy? (iii) Does Takanari have higher leaf N content per leaf area in the whole canopy? (iv) Does Takanari reallocate more N from old to canopy top leaves? We studied N distribution in stands of Takanari and a popular japonica rice cultivar Koshihikari. Difference in the total plant N and leaf N per plant between Takanari and Koshihikari was small. Whereas Takanari had a lower leaf N per plant N than Koshihikari, Takanari had a steeper vertical gradient of leaf N content than Koshihikari. The slope of vertical distribution of leaf N content (KN) was positively correlated with the light extinction coefficient (KL) in each cultivar. Whereas the KN–KL relationship of Koshihikari was similar to that of the general trend found in a recent meta‐analysis, Takanari had a significantly higher KN value than others when compared at a given KL. The KN values in Takanari were considered to be closer to the optimal KN than those in other species, which may contribute to higher productivity and higher N use efficiency in canopy photosynthesis.

Authors: Wu Zhenyu , Gao Dasheng , Liu Ningning
Published: July 2017

An anion-functionalized nanoporous polymer was successfully prepared by quaternary ammonization and anion-exchange treatment method. The polymer was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, N2 adsorption/desorption isotherms and thermogravimetric analysis. Batch experiments were conducted to investigate the adsorption behavior of phosphate on the polymer. The results indicated that the experimental equilibrium data can be well described by the Langmuir model. The maximum adsorption capacity determined from the Langmuir model was 4.92 mg g−1. For kinetic study, the adsorption behavior followed the pseudo-second-order model. Thermodynamic studies indicated that the adsorption process was spontaneous and exothermic.
How Economies Change? - A Study of Spain and India

Published: July 2017

Comparing economies is a tricky affair because though the parameters are the same yet, the conditionality differ. It is like a comparison of dissimilar attributes. How to juxtapose attributes of one economy vis-à-vis another when the two have entirely different histories, cultures, geographies and other socio political conditions. However, the task before the authors of this paper was to do this very job – comparing economic development of Spain and India with the help of the evolution of industrialization. The present paper is based on the result of research done between July 2015 and January 2016 in the Department of Management Studies, IIT (ISM), Dhanbad, in the context of post doctoral Fellowship from the European Union program Erasmus Mundus AREAS+.

The interesting aspect of this study is that despite all constraints Indian economy has grown commendably in comparison to the leading economies of the world, particularly the Western Europe. It may be recalled that the Industrial Revolution that was a game changer for Europe, gave certain inherent advantages to the European countries where it originated. But over the years Indian growth story has been a transformational one, despite a sluggish growth and disadvantaged history of exploitation and subjugation. Moreover, a large and rapidly growing population plagued by illiteracy and poverty has been a further stumbling block. But, the Indian economy has grown despite these difficulties and compares well with many developed economies. The paper details the evolution of Spanish and Indian economies and is based on the research carried out by the main author under the guidance of the two co-authors.
