Published: September 2019

Abstract
As per energy and power productivity of a solar photovoltaic (SPV) system is evaluated, Partial Shading Conditions (PSC) play a significant role. Under PSC, the panels of a SPV modules receive various levels of solar irradiance, as a result power generation of a SPV system diminishes, and these losses in SPV panels may be decrease by changing the configuration of the panels in array/module. The panels may be configure in many different configuration such as Series(S), Parallel (P), Series Parallel (SP), Total Cross Tied (TCT), Bridge Linked (BL), and Honeycomb (HC) to improve the output energy and power efficiency. This work is aimed to present all the configuration that already been presented in literature and result of PSC on SPV systems are referenced and analyzed. There are four configuration 4×4 array of solar photovoltaic panels to be discussed in this paper. Four configuration are Series parallel (SP), total cross tied (TCT), bridge linked (BL), and honey comb (HC). Four simulated models were performed to decide to effect of shadow with 10 shading patterns. The simulated results shows as a power against voltage (PV) curves of 4×4 array of SPV under PSC for above mentioned configuration. The PV curve of the proposed configuration is enhanced the power efficiency and the minute and exact finding of global maximum peak is simpler. The test of the simulated modules and its theoretical results ensure the effective implementation of this techniques in hardware setup also. It is confront that this work will be a reference of useful and important information for researchers in Solar panel area. The work presented in this papers envisages to be a source.

Abstract
Model Predictive Control (MPC) has been a powerful control strategy as it has already been proved with simulation and experimental studies. In this study, MPC has been explored for the level control of a nonlinear benchmark quadruple tank system. MPC has been applied as a real-time control strategy for set point control and disturbance rejection. Rigorous simulations and experiments have been done and fairy compared with those from the use of decentralized PI controller. To validate the results, real-time experimental studies have also been carried out for two possible configurations. The application offers a new look at the performance of the MPC for complex systems control.

Published: September 2019

Abstract
The future of biodiesel is bright. However, biodiesel is vulnerable to oxidative degradation due to autoxidation. Adding antioxidant is a probable answer to achieve clean burning and improved combustion. This paper addresses experimental study the influence of antioxidant with WFO biodiesel on diesel engine performance. WFOME was produced through transesterification process. BHA and BHT have been used as antioxidants. Increased oxidation stability of B40 (60% diesel + 40% Biodiesel) was observed with accumulation of antioxidants. A 5HP engine was preferred for this study. The outcomes illustrate that antioxidant-treated B40 produced 2.15% to 4.78% higher brake thermal efficiency and BSFC by 2.08% to 4.74% compared to untreated B40. Reduction in nitrogen emissions in tune of 4 ppm to 8 ppm was observed during this research. Increased CO in tune of 8.54 to 17.08% has been pointed out. HC emissions were higher by 7.73 to 14.95%.
Mathematical model development of modified flow dispersion stress tensor in 2-D curvilinear flow domain
Authors: Akhtar M.P. , Sharma Nayan , Ojha C. S. P. 
Published: September 2019

Abstract
For 2-D simulation of curvilinear flow field, use of momentum equations involves flow dispersion stress terms. Dispersion Stress terms take into account the effect of secondary flow variation arisen due to integration of the product of discrepancy between depth averaged velocity and the true velocity distributions. The objective of this paper is to present empirical mathematical functions to evaluate these terms. These terms can be incorporated in the 2D depth averaged flow equations as an additional source/sink term. In this work, the derivation is done to get revised set of empirical relations are later used in development of enhanced 2D numerical model. When compared with earlier investigations, the proposed formulations are simplified and numerically compatible. It is expected that modified formulation for flow dispersion stress tensor will lead to more realistic and improved simulation of flow field in curved flow domain.

Published: September 2019

Abstract
In today’s competitive business deal the demand for any product is positively affected by its displayed stock level due to which the suppliers normally gave permission to his/her retailers for the delay in payment. We developed an inventory model to stem the auspicious conditions under which permissible delay in payment and displayed stock levels are beneficial for the manufacturing industry and business markets. In this decision model, for the permissible delay period; the retailer is permitted to postpone his/her payment for the products, which was bought without paying any interest. In particular, we analyze in this study the optimal renewal policy for non-instantaneous decaying products through variable demand. Furthermore, the results reveal that the optimum cost and time using the assistance of a numerical example which demonstrates the model with sensitivity analysis is carried out.
Gain Characteristics of InGaAsN Quantum Well Heterostructures with GaAs and InP Substrates
Authors: Khan M. I. , Sandhya K. , Khan A. M. , Alvi P. A. 
Published: September 2019

Abstract
The present paper reports the effect of substrate on the optical gain characteristics of InGaAsN material based quantum well (QW) heterostructure. To analyze the substrate effect on the optical gain, two substrate, namely, GaAs and InP have been chosen. Taking in to account both of the substrates, the quantum mechanical approach (k.p method) has been adopted to calculate the confinement of the carriers related with quantum well and the optical gain. In addition, for InGaAsN/InP heterostructure, the cladding effect has also been observed. The simulated results exhibit that the substrate has played a very important role in modifying the optical gain characteristics due to the presence of strain which comes into play due to the lattice discrepancy.
Chordomics: a visualization tool for linking function to phylogeny in microbiomes
Authors: McDonnell Kevin , Waters Nicholas , Howley Enda , Abram Florence 
Published: September 2019

Abstract

Summary
The overarching aim of microbiome analysis is to uncover the links between microbial phylogeny and function in order to access ecosystem functioning. This can be done using several experimental strategies targeting different biomolecules, including DNA (metagenomics), RNA (metatranscriptomics) and proteins (metaproteomics). Despite the importance of linking microbial function to phylogeny there are currently no visualization tools that effectively integrate this information. Chordomics is a Shiny-based application for linked -omics data analysis, allowing users to visualize microbial function and phylogeny on a single plot and compare datasets across time and environments.

Effects of temperature on reproductive timing and hatching success in a tropical fiddler crab
Authors: Chou Chun-Chia , Head Megan L , Backwell Patricia Ruth Yvonne 
Published: September 2019

Abstract
The timing of reproduction is critical to reproductive success in many animal species. Parents that can perceive and respond to environmental cues and time the hatching/birth of their offspring to optimal environmental conditions show higher reproductive success. Intertidal ectotherms are under particularly strong selection because larval development rates are temperature-dependent, and larvae must hatch during the highest spring tides to avoid high levels of inshore predation. Here we investigate whether female fiddler crabs, Austruca mjoebergi, can mitigate the effects of high temperatures by adjusting the timing of reproductive events and/or by behavioural compensation. We experimentally manipulated incubation temperatures between 30 and 36 °C, based on natural and predicted temperature conditions, and found that hatching success decreased linearly with increasing temperatures. However, temperature had no effect on the timing of fertilization or hatching, suggesting that larval development rate was not temperature-dependent. Across the tested temperatures, females did not adjust egg size, the amount of yolk in each egg, larvae size or clutch size. In conclusion, high temperatures prevented clutches from reaching the hatching stage, but within the range of temperatures that facilitated hatching, there was no evidence of behavioural compensation and no discernible effect of temperature on reproductive timing.
Risk Factors for Kaposi’s Sarcoma–Associated Herpesvirus DNA in Blood and in Saliva in Rural Uganda
Authors: Nalwoga Angela , Nakibuule Marjorie , Marshall Vickie , Miley Wendell , Labo Nazzarena , Cose Stephen , Whitby Denise , Newton Robert 
Published: September 2019

Abstract

Background
Detectable Kaposi’s sarcoma–associated herpesvirus (KSHV) DNA in blood and increased antibody titres may indicate KSHV reactivation, while the transmission of KSHV occurs via viral shedding in saliva.

Methods
We investigated the risk factors for KSHV DNA detection by real-time polymerase chain reaction in blood and by viral shedding in saliva, in 878 people aged 3 to 89 years of both sexes in a rural Ugandan population cohort. Helminths were detected using microscopy and the presence of malaria parasitaemia was identified using rapid diagnostic tests. Regression modelling was used for a statistical analysis.

Results
The KSHV viral load in blood did not correlate with the viral load in saliva, suggesting separate immunological controls within each compartment. The proportions of individuals with a detectable virus in blood were 23% among children aged 3–5 years and 22% among those 6–12 years, thereafter reducing with increasing age. The proportions of individuals with a detectable virus in saliva increased from 30% in children aged 3–5 years to 45% in those aged 6–12 years, and decreased subsequently with increasing age. Overall, 29% of males shed in saliva, compared to 19% of females (P = .008).

Conclusions
Together, these data suggest that young males may be responsible for much of the onward transmission of KSHV. Individuals with a current malaria infection had higher levels of viral DNA in their blood (P = .031), compared to uninfected individuals. This suggests that malaria may lead to KSHV reactivation, thereby increasing the transmission and pathogenicity of the virus.
Prehistoric avifaunas from the Kingdom of Tonga
Authors: Worthy Trevor H , Burley David V 
Published: September 2019

AbstractAvifaunas derived from Lapita archaeological sites excavated between 2004 and 2014 from four sites in the Vava'u Group and two on Tongatapu, Kingdom of Tonga are described, revealing birds encountered by the first human arrivals. A total of 741 identifiable bones revealed 24 avian taxa, among which terrestrial birds, especially rails, pigeons and parrots, were the most abundant. At a minimum, eight taxa, or 50% of the original non-passerine land bird diversity in the sample, are globally extinct. These include two megapodes (Megapodius alimentum and a larger unnamed megapode), three pigeons (a large Caloenas sp. indet., Didunculus placopedetes and Ducula shutleri sp. nov.), two rails (Hypotaenidia vavauensis sp. nov. and an unnamed one) and the parrot Eclectus infectus. The rail H. vavauensis was restricted to Vava'u and was flightless, with reduced wings, and larger than Hypotaenidia woodfordi of the Solomons, the largest congener hitherto found in the Pacific. The pigeon Du. shutleri was volant, but was the largest species in its genus and was widespread in the Kingdom. The evolution of Tongan avifaunas is related to varying ages (Pliocene to Pleistocene) of the island groups, where geological youth apparently precluded true giantism in the fauna.
Quantum measurements and contextuality
Authors: Griffiths Robert B. 
Published: September 2019

In quantum physics, the term ‘contextual’ can be used in more than one way. One usage, here called ‘Bell contextual’ since the idea goes back to Bell, is that if
A
,
B
and
C
are three quantum observables, with
A
compatible (i.e. commuting) with
B
and also with
C
, whereas
B
and
C
are incompatible, a measurement of
A
might yield a different result (indicating that quantum mechanics is contextual) depending upon whether
A
is measured along with
B
(the {
A
,
B
} context) or with
C
(the {
A
,
C
} context). An analysis of what projective quantum measurements measure shows that quantum theory is Bell non-contextual: the outcome of a particular
A
measurement when
A
is measured along with
B
would have been exactly the same if
A
had, instead, been measured along with
C
. A different definition, here called ‘globally (non)contextual’ refers to whether or not there is (non-contextual) or is not (contextual) a single joint probability distribution that simultaneously assigns probabilities in a consistent manner to the outcomes of measurements of a certain collection of observables, not all of which are compatible. A simple example shows that such a joint probability distribution can exist even in a situation where the measurement probabilities cannot refer to properties of a quantum system, and hence lack physical significance, even though mathematically well defined. It is noted that the quantum sample space, a projective decomposition of the identity, required for interpreting measurements of incompatible properties in different runs of an experiment using different types of apparatus, has a tensor product structure, a fact sometimes overlooked.

Relating causal and probabilistic approaches to contextuality
Authors: Jones Matt 
Published: September 2019

A primary goal in recent research on contextuality has been to extend this concept to cases of inconsistent connectedness, where observables have different distributions in different contexts. This article proposes a solution within the framework of probabi- listic causal models, which extend hidden-variables theories, and then demonstrates an equivalence to the contextuality-by-default (CbD) framework. CbD distinguishes contextuality from direct influences of context on observables, defining the latter purely in terms of probability distributions. Here, we take a causal view of direct influences, defining direct influence within any causal model as the probability of all latent states of the system in which a change of context changes the outcome of a measurement. Model-based contextuality (M-contextuality) is then defined as the necessity of stronger direct influences to model a full system than when considered individually. For consistently connected systems, M-contextuality agrees with standard contextuality. For general systems, it is proved that M-contextuality is equivalent to the property that any model of a system must contain ‘hidden influences’, meaning direct influences that go in opposite directions for different latent states, or equivalently signalling between observers that carries no information. This criterion can be taken as formalizing the ‘no-conspiracy’ principle that has been proposed in connection with CbD. M-contextuality is then proved to be equivalent to CbD-contextuality, thus providing a new interpretation of CbD-contextuality as the non-existence of a model for a system without hidden direct influences.

The problem of quantum correlations and the totalitarian principle
Authors: Cabello Adán 
Published: September 2019

The totalitarian principle establishes that ‘anything not forbidden is compulsory’. The problem of quantum correlations is explaining what selects the set of quantum correlations for a Bell and Kochen–Specker (KS) contextuality scenario. Here, we show that two assumptions and a version of the totalitarian principle lead to the quantum correlations. The assumptions are that there is a non-empty set of correlations for any KS contextuality scenario and a statistically independent realization of any two KS experiments. The version of the totalitarian principle says that any correlation not forbidden by these assumptions can be produced. This paper contains a short version of the proof (presented elsewhere) and explores some implications of the result.

Hilbert space multidimensional modelling of continuous measurements
Authors: Busemeyer J. R. , Wang Z. 
Published: September 2019

Data fusion problems arise when a researcher needs to analyse results obtained by measuring empirical variables under different measurement contexts. A context is defined by a subset of variables taken from a complete set of variables under investigation. Multiple contexts can be formed from different subsets, which produce a separate distribution of measurements associated with each context. A context effect occurs when the distributions produced by the different contexts cannot be reproduced by marginalizing over a complete joint distribution formed by all the variables. We propose a Hilbert space multidimensional theory that uses a state vector and measurement operators to account for multiple distributions produced by different contexts.
