Scheduling Job Queue On Hadoop

Hadoop is a free, Java-based programming system that backings the preparing of vast informational collections in a Parallel and disseminated figuring condition. Enormous Data in many organizations are handled by Hadoop by presenting the employments to Master. Estimate based booking with maturing has been perceived as a compelling way to deal with certification powerful and close ideal framework reaction times. Hadoop Fair Sojourn Protocol (HFSP), “a scheduler acquainting this procedure with a genuine, multi-server, complex and generally utilized framework, for example, Hadoop”. In this paper, we introduce the plan of another booking convention that caters both to a reasonable and productive use of bunch assets, while endeavoring to accomplish short reaction times. Our answer actualizes a size-based, preemptive planning discipline. The scheduler apportions group assets with the end goal that employment measure data is surmised while the occupation gains ground toward its fruition. Planning choices utilize the idea of virtual time and bunch assets are centered around employments as per their need, processed through maturing. This guarantees neither little nor extensive employments experience the ill effects of starvation. The result of our work appears as an undeniable scheduler usage that coordinates consistently in Hadoop named HFSP. Measure based planning for HFSP receives offering need to little occupations that they won't be backed off by expansive ones. The “Shortest Remaining Processing Time (SRPT) strategy, which organizes occupations that need minimal measure of work to finish, is the one that limits the mean reaction time (or visit time), that is the time that goes between an occupation accommodation and its fruition”. We Extend HFSP to respite occupations with Higher SRPT and permit other holding up employments in Queue in view of FCFS.
Abelian covers of algebraic varieties.

More precisely, under our assumptions V χ e G * the eigensheaf of π# Θχ on which the group acts via the character χ is a line b ndle that we denote by L'. On the other hand, to every component of the branch locus D there corresponds naturally its inertia group, which is a cyclic subgroup of G, and a character of the inertia group. We denote by DH φ the union of all the components of the branch locus that have same inertia group H and same character ψ. The line bundles Lx and the divisors DH{I} are then the required building data.
Analysis of COVID-19 Risk Perception and Its Correlates among University Students in Ghana

Monitoring students’ risk perception forms part of emergency management during public health emergencies. Thus, public risk perception generally triggers attitudes, emotional responses, and prevention behaviors, which affect the evolution of emergencies and disease control strategies. However, research has paid less attention to the COVID-19 risk perception of students in Ghana. This study assessed the prevalence of COVID-19 risk perception and further identified its correlates among university students. In this study, 882 students from two public universities in Ghana were conveniently recruited. The data were analysed using frequency counts, percentages, and ordered logistic regression. The study revealed the prevalence of a high degree of COVID-19 risk perception among almost half (47.4%) of the sampled students. Results from ordered logistic regression analysis showed that age, sex, religion, use of professional and social media platforms, level (years) of study, and COVID-19 knowledge were significant correlates of COVID-19 risk perception. The dissemination of appropriate COVID-19 information and behavior-change communication to such relatively high-risk behavior sub-groups could help counter the debilitative effects of non-altruistic attitudes because of COVID-19 risk perception.
An Efficient Machine Learning Optimization Model for Route Establishment Mechanism in IoT Environment

Internet of Things (IoT) provides interconnection of various wireless communication devices, which offers both ubiquitous accessibility of devices and in-built intelligence capacity. IoT offers interaction with devices and provides sufficient capability advantages of networking and socialization with consideration of intermediate devices. RPL (Routing Protocol for low-power and Lossy Networks) is an attractive model for effective routing techniques in the wireless medium. The increase in demand for wireless systems in terms of energy, reliability, stability, and scale routing IPv6 over 6L0WPAN is being adopted. This research developed an optimized machine learning model (WOABC) routing protocol for route establishment in IoT networks. The constructed RPL routing protocol incorporates an optimization approach for the identification of the best and worst routes in the network. The proposed WOABC evaluates the routing path for data transmission between nodes through optimization techniques for effective route establishment. The optimization of routes is performed with whale optimization techniques. The developed whale optimization technique is incorporated in machine learning networks. Also, the proposed WOABC utilizes an optimization membership function for the identification of the optimal path in the network. The performance of the proposed WOABC is compared with existing techniques such as RPL and Speed – IoT. The comparative analysis showed that the performance of the proposed WOABC is ~3% increased throughput. The performance of the proposed WOABC is significant compared with the existing RPL routing protocol.
Longitudinal associations of parent-child communication, dating behaviors, decision-making processes, and sex initiation among United States Latina/o adolescents

Objective This study examined differences and identified developmental predictors of oral, vaginal, and anal intercourse initiation across generational status among Latina/o adolescents of both genders. More specifically, we compare generational status and gender differences in the longitudinal predictions from parent-child sex communication and dating behaviors to sex initiation 5 years later, and how these associations may be mediated by perceived peer norms, intentions, and attitudes regarding sex among Latina/o adolescents. Methods Using prospective longitudinal data from the Healthy Passages™ project collected in Houston and Los Angeles, Latina/o girls (n = 879) and boys (n = 885) who were identified as 1st- (18%), 2nd- (58%), or 3rd (24%)-immigrant generational status reported on their dating behaviors and parent-child communication about sex at 5th grade (M age = 11.12 years), their perceived peer norms and attitudes regarding sex at 7th grade (M age = 13.11 years), and if they had initiated oral, vaginal, or anal sexual intercourse by 10th grade (M age = 16.06 years). Results Third-generation Latina girls were more likely than 1st- and 2nd-generation Latinas to have initiated sexual intercourse by 10th grade. More advanced dating behaviors in 5th grade had a positive association with sex initiation for all generational status groups among Latino boys, but only among 1st-generation Latina girls. Moreover, mediating decision-making processes of peer norms and attitudes differed for each group. Conclusion Pre-adolescent dating behaviors are associated with long-term differences in adolescents’ sexual behaviors, which may point to targets for prevention efforts. Acculturation differences may contribute to different ways in which adolescents decide to engage in sexual intercourse based on the previous dating experiences.
The Perception of English Vowels by Kurdish EFL Learners

This paper investigates English vowel perception in a formal classroom setting by Central Kurdish (CK) learners of English (i.e. EFL learners at university level in The Kurdistan Region of Iraq). Ten English vowels were used as stimuli: five monophthongs with similar qualities but different quantities. The participants included 30 first year English majors. They were tested while performing a discrimination task. The task to discriminate 50 pairs of RP English vowel contrasts was an AX style task. The RP vowels differed from the CK vowels in both quality and quantity. As stated by the Perceptual Assimilation Model L2, the results demonstrated a variety of assimilation types (PAM-L2). It was more difficult to distinguish between two sets of similar vowels. Furthermore, closer vowel contrasts in the vowel space were more difficult to distinguish. To the best of our knowledge, no previous research has looked into Kurdish EFL students' perceptions of English vowels. The perception of English vowels by these Kurdish English learners mostly agreed with PAM's predictions, and the results of the discrimination task ranged from excellent to poor.
Evolution of the equation of state parameters of cosmological tachyonic field components through mutual interaction

We study the perturbed equation of state (EOS) parameters of the cosmological tachyonic scalar field components and their mutual time-dependent interaction. It is shown that the discrete temperature-dependent pattern of the EOS emerges from an initial continuum along the evolution of the universe. This leads to two major components in form of dark energy and dark matter, and also suggests a solution to the cosmological constant problem and the coincidence problem.

LAS CELDAS SOLARES COMO ALTERNATIVA PEDAGÓGICA EN LA ENSEÑANZA DE LA ELECTRICIDAD

In this work, solar cells are used to teach middle school students the basic concepts of electricity and the importance of using renewable and clean energy sources to generate electricity. To achieve these objectives, a program of pedagogical activities was designed and developed in which different methodologies were used and several activities were carried out within the teaching-learning process. The activities taught the new generations the advantages of using solar energy to obtain electricity, over the use of non-renewable energy sources that are mainly used today. Through the operation of a high technology device such as the solar cell, concepts of electric current, voltage, resistance and electrical power were taught. Teaching of electricity concepts in this novel way is an example of innovation in the teaching-learning process at the level of secondary education, which involves the promotion of the use of energy from renewable sources in traditional teaching. Learning and motivation of students were evidenced in the development of school projects in which they used the solar cells.
Sailing through the storm – performance of Russian manufacturing subsidiaries of multinational corporations in the first year of the COVID-19 pandemic

ABSTRACT The aim of this study is to depict the performance of Russian manufacturing subsidiaries of multinational corporations during the first year of the COVID-19 pandemic. Using a unique handcrafted database of financial reports from 259 subsidiaries for 2019 and 2020, we retraced three indicators of business robustness: the dynamics of revenues, positive profitability, and the level of financial solvency. Most of the studied subsidiaries (85%) were able to withstand the crisis and maintain satisfactory financial solvency. Revenues decreased in 2020 to 40% of the studied subsidiaries, and the share of loss-making subsidiaries reached 31%. However, more than 40% of the studied subsidiaries achieved both an increase in revenues and positive profitability of sales in 2020. In this respect we may assess the level of ‘ownership advantage’ of multinational corporations regarding assisting their subsidiaries to achieve different elements of business robustness during the pandemic.

Epidemiology and Financial Burden of Adult Chronic Hypoparathyroidism

Chronic hypoparathyroidism is characterized by low serum calcium, increased serum phosphorus, and inappropriately low or decreased serum parathyroid hormone. This rare disorder is associated with a variety of complications. The prevalence, incidence, mortality, financial burden, and epidemiology of complications of this disorder are not well understood. This narrative review summarizes current information on the epidemiology and complications of chronic hypoparathyroidism. The reported prevalence of chronic hypoparathyroidism ranges from 6.4–37/100,000, and the incidence is reported to be 0.8–2.3/100,000/year. Mortality is not increased in studies from Denmark or South Korea but was increased in studies from Scotland and Sweden. The financial burden of this disorder is substantial because of increased health care resource utilization in two studies but not well quantitated. Recognized complications include hypercalciuria, nephrocalcinosis, kidney stones, and chronic kidney disease; low bone turnover and possibly upper extremity fractures; cardiac and vascular calcifications; basal ganglia calcifications, cataracts, infections, neuropsychiatric complications, and difficulties with pregnancy. This review concludes that chronic hypoparathyroidism is a rare disorder associated with significant morbidity that may not increase overall mortality but is associated with a substantial financial burden. © 2022 The Authors.

Falando sobre infertilidade

infertilidade pode ser definida como a ausência de gravidez após um ano de relações sexuais regulares, sem o uso de qualquer método contraceptivo, por exemplo, pílula anticoncepcional, preservativo, DIU (dispositivo intra-uterino) dentre outros. Hoje em dia os casais inférteis representam 10% a 15% de todos os casais. Vários fatores característicos do mundo moderno estão contribuindo para o aumento dos índices de infertilidade, dentre eles, alimentação não-balanceada (alto teor de gorduras, conservantes, corantes artificiais etc.), vida sedentária (especialmente a falta de exercício físico), estresse e principalmente, a tendência da mulher em adiar a maternidade, devido ao seu papel no mercado de trabalho, optando pela gestação após os 30 ou 35 anos.

A dual‐band high‐gain magneto‐electric dipole antenna array for millimeter‐wave applications

In this article, a compact dual‐band magneto‐electric dipole (MED) antenna array with high gain is proposed, which is fed by a 1‐to‐4‐way feeding structure composed of substrate integrated waveguide (SIW) aperture‐coupled. The dual‐band MED antenna consists of a pair of U‐shaped patches of different sizes used as electric dipoles and two pairs of vertical metalized vias work as magnetic dipoles. By analyzing the working mode of the MED unit at each resonance frequency and the complementary principle of radiation patterns, the dual‐band characteristics of the antenna are further illustrated. Measured results of the fabricated antenna array show that ‐10 dB impedance bandwidth is 12.5% (from 22.5 to 25.5 GHz) with a peak gain of 11 dBi in the low‐frequency band and 5.9% (from 40.5 to 42.9 GHz) with a peak gain of 10.5 dBi in the high‐frequency band. Moreover, the radiation patterns in E‐and H‐planes are almost symmetrical at two operating bands with the maximum gain in the z‐direction. The proposed dual‐band MED antenna array has the merits of high gain, easy integration and simple structure.
Predicting the Performance of a 26 GHz Transconductance Modulated Downconversion Mixer as a Function of LO Drive and DC Bias

The dependency of RF performance on the local oscillator (LO) drive amplitude and DC bias is an important topic for RF mixers, especially as carrier frequency increases and generation of RF power thus becomes more complex. The prediction of mixer performance, without initial reliance on full circuit simulations, can provide important insights. In this work, mathematical models without the prior use of circuit simulation are developed, leading to a strategy to predict the conversion gain (Gc), DC current, 1 dB input compression point (IP1dB) and third order input intercept point (IIP3) for a SiGe bipolar transistor transconductance mixer. The models show the possibility to trade-off LO RF power and DC bias to achieve a desired performance. The concepts allow a prediction of the necessary DC bias required to support a chosen LO level and desired conversion transconductance or linearity. The mathematical model results, circuit simulation results, and measured hardware results from a 26 GHz prototype of a single-ended mixer are presented and compared, showing good agreement. In a lab-measured example, LO power reduction from +10 dBm to +3 dBm resulted in only a 1 dB reduction in conversion gain, by modifying the DC bias as predicted. The peak conversion gain predicted by the models is within 2.0 dB of circuit simulation and 2.5 dB of measured PCB results. The RMS error for predicted DC current, compared to circuit simulation, is 1.9 mA or better.
Computer-Aided Screening of Phytoconstituents from Ocimum tenuiflorum against Diabetes Mellitus Targeting DPP4 Inhibition: A Combination of Molecular Docking, Molecular Dynamics, and Pharmacokinetics Approaches

Diabetes mellitus is a major global health concern in the current scenario which is chiefly characterized by the rise in blood sugar levels or hyperglycemia. In the context, DPP4 enzyme plays a critical role in glucose homeostasis. DPP4 targets and inactivates incretin hormones such as glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP) as physiological substrates, which are essential to regulate the amount of insulin that is secreted after eating. Since the inactivation of incretins occurs, the hyperglycemic conditions continue to rise, and result in adverse physiological conditions linked with diabetes mellitus. Hence, inhibition of DPP4 has been the center of focus in the present antidiabetic studies. Although few DPP4 inhibitor drugs, such as alogliptin, saxagliptin, linagliptin, and sitagliptin, are available, their adverse effects on human metabolism are undeniable. Therefore, it becomes essential for the phytochemical intervention of the disease using computational methods prior to performing in vitro and in vivo studies. In this regard, we used an in-silico approach involving molecular docking, molecular dynamics simulations, and binding free energy calculations to investigate the inhibitory potential of Ocimum tenuiflorum phytocompounds against DPP4. In this regard, three phytocompounds (1S-α-pinene, β-pinene, and dehydro-p-cymene) from O. tenuiflorum have been discovered as the potential inhibitors of the DPP4 protein. To summarize, from our in-silico experiment outcomes, we propose dehydro-p-cymene as the potential lead inhibitor of DPP4 protein, thereby discovering new a phytocompound for the effective management of hyperglycemia and diabetes mellitus. The reported compound can be taken for in vitro and in vivo analyses in near future.
Density, delinquency and design: formal and informal control and the built environment.

This study reviews the literature concerning the general impact of the physical environment on social disorganization, crime, and juvenile delinquency, with a specific focus on the relationship between household density, building density-design, and juvenile delinquency. Two perspectives on control are shown to have developed in an environmental context. One emphasizes the capacity of the built environment to impair informal social control, and the other focuses on the attraction of the same environments for agents of formal social control (the police). A path model is presented. showing that building density-design is an independent predictor of marijuana use and supporting the view that the physical environment can affect informal control. The model also shows that building density-design is a significant predictor of police presence. thus giving empirical support to the notion that the physical environment can affect formal control.
Short Circuit Current Calculation Method of Doubly-Fed Induction Generator with Crowbar Protection Based on Flux Transient Characteristics

Abstract With the wide application of doubly-fed induction generator (DFIG), accurate calculation and analysis of the short circuit currents of DFIG with crowbar protection has become very important key to realizing the low voltage ride through (LVRT) capability of DFIG and establishing the corresponding grid protection scheme. In view of this, a method to calculate the short circuit currents of DFIG with crowbar protection when different types of fault occur in the grid is proposed in this paper. First, the DFIG stator and rotor 2nd-order differential equations in the cases of grid symmetrical fault and asymmetrical fault are established respectively. And the short circuit current calculation model when crowbar resistance remains unchanged in the fault duration is obtained. On this basis, the short circuit current calculation model when crowbar resistance varies in the fault duration is derived. And then, the influence of crowbar resistance and DFIG rotor speed on the short circuit current calculation model is analyzed, including the variation pattern of flux eigenvalues with the crowbar resistance, and the variation feature of flux amplitude and phase angle with the rotor speed. Besides, the transient variation characteristics of different flux components are studied. Finally, time-domain simulation tests verify that the proposed calculation method is correct and applicable to different types of crowbar circuits in the market. Besides, the influence of crowbar resistance and DFIG rotor speed on the stator short circuit current peak, peak time and current frequency in different fault cases is revealed.
