IoT based Smart System to Support Agricultural Parameters: A Case Study
Creators: name: Abhijit Pathak
Publisher: name: figshare
Year: 2020
Subjects: Computer Engineering

description: Now-a-days, the natural irrigation system is under pressure due to the growing water shortages, which are mainly caused by population growth and climate change. Therefore, the control of water resources to increase the allocation of retained water is very important. It has been observed in the last two decades, especially in the Indian sub-continent, the change of climate affects the agricultural crops production significantly. However, the prediction of good harvests before harvesting, enables the farmers as well as the government officials to take appropriate measures of marketing and storage of crops. Some strategies for predicting and modelling crop yields have been developed, although they do not take into account the characteristics of climate, and they are empirical in nature. In the proposed system, a Cuckoo Search Algorithm has been developed, allowing the allocation of water for farming under any conditions. The various parameters such as temperature, turbidity, pH., moisture have been collected by using Internet of Things (IoT) platform, equipped with related sensors and wireless communication systems. In this IoT platform the sensor data have been displayed in the cloud environment by using ThingSpeak. The data received in the ThingSpeak used in the proposed Cuckoo Search Algorithm, allowing the selection of appropriate crops for particular soil.

description: There is no quick and easy method to analyze the impact of population growth on local government finances. No computer program can systematically incorporate all important characteristics of a particular new firm and a specific community into a finely tuned mathematical model and then magically compute detailed and precise estimates of new revenues and expenditures. Forecasting local impacts is still more art than science, especially in smaller communities. Knowledge of local conditions is of the utmost importance. The following overview of existing methods of raising revenues and providing services should help community leaders minimize the fiscal impacts of growth.
Evolution and Yields of Extremely Metal Poor Intermediate Mass Stars

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Intermediate mass stellar evolution tracks from the main sequence to the tip of the AGB for five initial masses (2 to 6Msun) and metallicity Z=0.0001 have been computed. The detailed 1D structure and evolution models include exponential overshooting, mass loss and a detailed nucleosynthesis network with updated nuclear reaction rates. The network includes a two-particle heavy neutron sink for approximating neutron density in the He-shell flash. It is shown how the neutron-capture nucleosynthesis is important in models of very low metallicity for the formation of light neutron-heavy species, like sodium or the heavy neon and magnesium isotopes. The models have high resolution, as required for modeling the third dredge-up. All sequences have been followed from the pre-main sequence to the end of the AGB when all envelope mass is lost. Detailed structural and chemical model properties as well as yields are presented. This set of stellar models is based on standard assumptions and updated input physics. It can be confronted with observations of extremely-metal poor stars and may be used to assess the role of AGB stars in the origin of abundance anomalies of some Globular Cluster members of correspondingly low metallicity.

description: Previous studies have shown that health information technologies have a positive impact on health systems. Electronic health record (EHR) systems are one of the most promising applications, demonstrating a positive effect in high income countries. On the other hand, robust evidence for low and middle income countries is still spare. The aim of this study is to initiate a carefully planned nationwide EHR system in Vietnam by assessing the core readiness. The assessment structure is mainly based on previous research, which recommends a readiness assessment prior to to an EHR system implementation. To collect data, participant observation, document analysis and an in-depth interview were used. This study has revealed new insights into the current situation on EHR in Vietnam. The Ministry of Health is currently working on improving the conditions for future implementation of a Vietnamese EHR system. There are issues with the current way of handling health records. These issues are encouraging the Ministry of Health to work on identifying the next steps for an EHR system implementation. The integration of an EHR system with current systems seems to be challenging as most systems are commercial, closed source and very likely have no standardised interface. In conclusion, this study identifies points which need to be further investigated prior to an implementation. Generally, health care workers show good awareness of new technologies. As the Vietnam's health care system is centrally organised, there is the possibility for a nation-wide implementation. This could have a positive impact on the health care system, however, besides rigours planning also standards need to be followed and common interfaces implemented. Finally, this assessment has focused on only one level of readiness assessment. Further research is needed to complete the assessment.

description: For two-dimensional Heisenberg antiferromagnet we present an analysis of topological coreless excitations having a stripe form. These textures are characterized by singularities at boundaries. A detailed classification of the stripe textures results in a certain analogy with the coreless excitations in $^3He-A$ phase: Mermin-Ho and Anderson-Toulouse coreless vortices. The excitations of the last type may have a low bulk energy. The stripe textures may be observed as an occurrence of short-range incommensurate order in the antiferromagnetic environment.

description: One-loop scattering amplitudes in N=4 super Yang-Mills (SYM) theories are analyzed in the paradigm of maximal helicity violating Feynman diagrams. There are very limited number of loop integrals to be evaluated. For a process with n external particles, there are only [n/2]-1 generically independent integrals. Furthermore, the relations between leading N_c amplitudes A_{n;1} and sub-leading amplitudes A_{n;c} are found to be identical to those obtained from conventional field theory calculations, which can be interpreted as an indirect support for the paradigm.

description: Continuing the program of math.SG/0012067 and math.SG/0310450, we introduce refinements of the Donaldson-Smith standard surface count which are designed to count nodal pseudoholomorphic curves and curves with a prescribed decomposition into reducible components. In cases where a corresponding analogue of the Gromov-Taubes invariant is easy to define, our invariants agree with those analogues. We also prove a vanishing result for some of the invariants that count nodal curves.

description: To date, only 69 pulsars have been identified with a detected pulsed radio emission below 100 MHz. A LOFAR-core LBA census and a dedicated campaign with the Nançay LOFAR station in stand-alone mode were carried out in the years 2014$-$2017 in order to extend the known population in this frequency range. In this paper, we aim to extend the sample of known radio pulsars at low frequencies and to produce a catalogue in the frequency range of 25-80 MHz. This will allow future studies to probe the local Galactic pulsar population, in addition to helping explain their emission mechanism, better characterising the low-frequency turnover in their spectra, and obtaining new information about the interstellar medium through the study of dispersion, scattering, and scintillation. We observed 102 pulsars that are known to emit radio pulses below 200 MHz and with declination above \SI{-30}{\degree}. We used the the Low Band Antennas (LBA) of the LOw Frequency ARray (LOFAR) international station FR606 at the Nançay Radio Observatory in stand-alone mode, recording data between 25-80 MHz. complemented with a few additional candidates. Out of our sample of 102 pulsars, we detected 64. We confirmed the existence of ten pulsars detected below 100 MHz by the LOFAR LBA census for the first time \citep{bilous_lofar_2019} and we added two more pulsars that had never before been detected in this frequency range. We provided average pulse profiles, DM values, and mean flux densities (or upper limits in the case of non-detections). The comparison with previously published results allows us to identify a hitherto unknown spectral turnover for five pulsars, confirming the expectation that spectral turnovers are a widespread phenomenon.

description: We report on a 19 ks observation of the pulsar J1016-5857 with the Chandra X-ray Observatory. This "Vela-like" pulsar has rotation period 107 ms, characteristic age 21 kyr, and spin-down power 2.6e36 ergs/s. A relatively bright centrally peaked source of radius ~25" around the radio pulsar position has a spectrum that is well fitted by an absorbed power law with photon index 1.32+-0.25. We regard this as a newly identified pulsar wind nebula that we designate PWN G284.0-1.8. We do not detect the pulsar either as a point X-ray source or as a pulsed source in a 55 ks observation with the Rossi X-ray Timing Explorer. The isotropic PWN luminosity is 3e32 ergs/s in the 2-10 keV range, for a distance of 3 kpc that is consistent with the measured neutral hydrogen column density. The unpulsed flux from the pulsar is less than 30% of the measured PWN flux. The brightest component of the PWN, near the pulsar, shows extended emission of size ~2" that may indicate, by analogy with other young pulsars, the wind termination shock. In the Chandra image we also detect a very faint extended structure ~1' by 2' in size that is highly asymmetric about the pulsar position. This structure is a good match in width and position angle to the tip of a "finger" of radio emission that appears to connect to the nearby supernova remnant G284.3-1.8, but we cannot characterize it further with the available data. There is a variable X-ray point source only 1.5 arcmin from the pulsar, which we identify using optical spectroscopy as an accreting binary.

description: Growing evidences indicated that the imbalance of gut microbiota is closely related to the occurrence of chronic constipation. It has also been reported that gastrointestinal (GI) motility and gut microbiota have reciprocal effects, with the gut microbes accelerated GI transit, which could alter the composition and structure of microbial communities. Meanwhile, several main probiotics were used to treat constipation in animal and human studies. Therefore, it is necessary to study the effect of P9 on the gut microbiota of patients with chronic constipation.

description: We derive a path-integral description of the vortex state of a fermionic superfluid in the crossover region between the molecular condensate (BEC) regime and the Cooper pairing (BCS) regime. This path-integral formalism, supplemented by a suitable choice for the saddle point value of the pairing field in the presence of a vortex, offers a unified description that encompasses both the BEC and BCS limits. The vortex core size is studied as a function of the tunable interaction strength between the fermionic atoms. We find that in the BEC regime, the core size is determined by the molecular healing length, whereas in the BCS regime, the core size is proportional only to the Fermi wave length. The observation of such quantized vortices in dilute Fermi gases would provide an unambiguous proof of the realization of superfluidity in these gases.

description: Quality by design (QbD) became an indispensable part of pharmaceutical quality. To increase product quality, understanding how formulation and manufacturing process variables influence product quality is essential. In that holistic context, this work attempted to develop transferable methods to help increase process understanding, control and robustness. For the purpose of these goals a recombinant protein production process with E. coli as a host was used. The product was formed as inclusion bodies (IB). A high throughput method for IB sizing using nano-particle tracking analysis (NTA) was developed and established. The effect of temperature oscillations on IB solubility could not be investigated as planned due to insufficient heating and cooling performance of the reactor setup. A softsensor, previously developed in the working group, has been further developed and was used for real-time estimation of the specific substrate uptake rate qS. Therefore the obligatory real-time biomass estimation was decoupled from the carbon balance and realized using a weighted average approach, enabling biomass estimation robust against substrate accumulation. Subsequently, the sensor was used to establish a closed loop control of qS. Because of the declining physiological capacity of the host to metabolize substrate (qScrit) during induction phase, a logical query was developed to detect reaching qScrit in real-time. The physiological closed loop control was used to successfully avoid substrate and metabolite accumulation throughout induction phase of an industrial relevant production process.
The Supergravity Dual of the BMN Matrix Model

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We propose type IIA supergravity solutions dual to the 1/2 BPS vacua of the BMN matrix model. These dual solutions are analyzed using the Polchinski-Strassler method and have brane configurations of concentric shells of D2 branes (or NS5 branes) with various radii and D0 charge. These branes can be viewed as polarized from $N$ D0 branes by a transverse R-R magnetic 6-form flux and an NS-NS 3-form flux. In the region far from branes, the solutions reduce to perturbation around the near horizon geometry of $N$ D0 branes, by turning on these R-R and NS-NS fluxes, which are dual to the deformation of the BFSS matrix model by adding mass terms and the Myers term. The solutions with these additional fluxes preserve 16 supersymmetries. We also briefly discuss these fluxes in the possible supergravity duals of M(atrix) theories on less supersymmetric plane-waves.

description: Due to the progressive advancement of science and technology, rapid development, and population increment in an uncontrolled way, the usage of plastic materials also expanded around the globe. Recently, it became a global challenge to manage, minimize and mitigate this plastic waste (PW) which is broadly publicized in the media and scientific articles. Though few research articles focused on the acute generation of plastic, poor management, and health risks and issues associated with PW. These articles stab to draw attention to these issues as well as explained future prospects and possible alternatives to plastic. From 1950 to 2020, 70 years plastic generation rate has increased by about 22233% which is alarming and uncontrolled. It is predicted that by 2050, the plastic production rate will be more than 650 million tons. However, though the USA produces maximum plastic India is at the top of the list for plastic pollution. Soil, water, human and marine life, and overall, the environment is greatly affected by PW. Hence, PW is getting increased in an uncontrolled way due to the low recycling rate. Therefore, the study aims to outline the critical discussion about global plastic production, current management practices, and mitigation measures to minimize the negative impact of plastic.

description: The current trend in world trade of agro-food, and the change in consumer demand patterns for food and agricultural products, has led to a fast growth of multi-national chains of retail stores in major cities in developing countries and growth in domestic retail store chains. Their presence opens a new market for high quality agro-food. While many products come from overseas, many can also be supplied locally by farmers or farmers’ co-operatives or associations provided that they meet the quality and supply standards required by the store. To study and identify specific benefits from this global economic trend that can be tapped by secondary crops farmers, specifically those living in medium altitude areas, two studies were conducted in two member countries of CAPSA-ESCAP, i.e., Indonesia and the Philippines, with assistance provided by the government of France. Product certification requirements by the retailers, and best practices on product certification by the various producers and processors from farms to retailers, were studied, analysed, and collated.

description: A novel method for extracting threshold voltage and substrate effect parameters of MOSFETs with constant current bias at all levels of inversion is presented. This generalized constant-current (GCC) method exploits the charge-based model of MOSFETs to extract threshold voltage and other substrate-effect related parameters. The method is applicable over a wide range of current throughout weak and moderate inversion and to some extent in strong inversion. This method is particularly useful when applied for MOSFETs presenting edge conduction effect (subthreshold hump) in CMOS processes using Shallow Trench Isolation (STI).

description: This thesis reports real life. I, the researcher taught my children at home for twenty years, intuitively solving educational problems, confronting the curriculum to find a way to enable them to learn at home despite learning difficulties. Having achieved success beyond my expectations, I reflected on that process, seeking out expert opinion and analyzed it. The result is this thesis - "an academic analysis of a lived experience" (Cairns, personal correspondence, 2005), an auto-ethnography. My children's learning problems focused my effort, thought and teaching practice upon literacy. There was no research question to direct the experience, only naive wonderings, "How can I help this child learn to read?" and later, "How did she learn so well?" These were later refined into more sophisticated research questions. The methodology of this experience was, "ad hoc" and the literature, instead of provokingresearch questions, hypothesis and design, was reviewed after the experience to answer and refine questions that had emerged from it. The literature helped interpret the lived experience and the lived experience helped evaluate the literature, pointing to urgently needed theory about home-learning. The research was carried out, "back to front."

El modelo se ha contrastado con los valores de mercado en las edades disponibles, mostrando su validez general. la evolucion de valor con la edad se adapta bien a una curva parabolica facil de paraetrizar para facilitar el proceso de valoracion... In this research production animals valuation models have been developed for milk cows. The work enables the solution of valuation problems in the animals insurance sector. The model uses the lactation curve, Wood's model (1967), in a quantitative way (milk production) as well in a qualitative way (production of fat and protein), week by week, in a period of four years of milk production, with the inclusion of parameters of seasonal variability due to birth date and farm size factor. The model is validated with market values, in the available ages, showing its general validity. The evolution of the variable value vs the variable age has a good fit with a parabolic function. it is easy to parametrize this function to facilitate the valuation process.

description: Low noise and high repetition rate optical frequency combs are desirable for many applications from timekeeping to precision spectroscopy. For example, gigahertz repetition rate sources greatly increase the acquisition speed of spectra in a dual-comb modality when compared to lower repetition rate sources, while still maintaining sufficient instantaneous resolution to resolve ro-vibrational signatures from molecules in a variety of conditions. In this paper, we present the stabilization and characterization of a turnkey commercial 1~GHz mode-locked laser that operates at telecom wavelengths (1.56 $μ$m). Fiber amplification and spectral broadening result in the high signal-to-noise ratio detection and stabilization of $\textit{f}_{\textit{ceo}}$ with 438 mrad of residual phase noise (integrated from 10$^2$ to 10$^7$ Hz). Simultaneously, we stabilize the beatnote between the nearest comb mode and a cavity stabilized continuous-wave laser at 1.55 $μ$m with 41 mrad of residual phase noise (integrated from 10$^2$ to 10$^7$ Hz). This robust, self-referenced comb system is built with off-the-shelf polarization-maintaining fiber components and will be useful for a wide range of low noise frequency comb applications that benefit from the increased repetition rate.

Note that for non-Boolean queries, the size of the query result may be far too large to be computed entirely within FPT time. We investigate the free-connex variant of submodular width and generalise Marx's result to non-Boolean queries as follows: For every class $Φ$ of CQs of bounded free-connex submodular width, within FPT-preprocessing time we can build a data structure that allows to enumerate, without repetition and with constant delay, all tuples of the query result. Our proof builds upon Marx's splitting routine to decompose the query result into a union of results; but we have to tackle the additional technical difficulty to ensure that these can be enumerated efficiently.

description: In this paper we deal with symplectic Lie algebras. All symplectic structures are determined for dimension four and the corresponding Lie algebras are classified up to equivalence. Symplectic four dimensional Lie algebras are described either as solutions of the cotangent extension problem or as symplectic double extension of $\Bbb RR^2$ by $\Bbb RR$. The difference in the choice of a certain model lies on the existence or not of a lagrangian ideal. Moreover all extensions of a two dimensional Lie algebra are determined, and so all solutions (up to equivalence) of the cotangent extension problem are given in dimension two. By studying the adjoint representation we generalize to higher dimensions finding obstructions to the existence of symplectic forms. Finally, as an appendix we compute the authomorphisms of four dimensional symplectic Lie algebras and the cohomology over $\Bbb RR$ of the solvable real four dimensional Lie algebras.

Neutrino spin-flavor oscillations in rapidly varying external fields

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study neutrino spin-flavor oscillations in presence of rapidly varying external fields. The general formalism for the description of neutrino oscillations in arbitrary rapidly varying external fields is elaborated. We obtain the effective Hamiltonian which determines the evolution of the averaged neutrino wave function. We apply the general technique to neutrino oscillations in rapidly varying magnetic fields. The special case of the constant transversal and twisting magnetic fields is studied. We evaluate the effect of neutrino spin-flavor oscillations in rapidly varying magnetic fields of the Sun. The numerical solutions of the Schroedinger equation with the Hamiltonian accounting for the constant transversal and twisting magnetic fields are presented. We compare them with our approximate analytical transition probability formula and reveal good agreement at high frequencies of the twisting magnetic field.

Thermal Production of Axinos in the Early Universe

description: We compute the thermal axino production rate in supersymmetric QCD to leading order in the gauge coupling. Using hard thermal loop resummation and the Braaten-Yuan prescription, we obtain a finite result in a gauge-invariant way, which takes into account Debye screening in the hot quark-gluon-squark-gluino plasma. The relic axino density from thermal reactions in the early Universe is evaluated assuming the axino is the lightest supersymmetric particle and stable due to R-parity conservation. From the comparison with the WMAP results, we find that axinos could provide the dominant part of cold dark matter, for example, for an axino mass of 100 keV and a reheating temperature of 10^6 GeV.

description: The Galactic Center black hole Sgr A* shows significant variability and flares in the submillimeter, infrared, and X-ray wavelengths. Owing to its exquisite resolution in the IR bands, the GRAVITY experiment for the first time spatially resolved the locations of three flares and showed that a bright region moves in ellipse-like trajectories close to but offset from the black hole over the course of each event. We present a model for plasmoids that form during reconnection events and orbit in the coronal region around a black hole to explain these observations. We utilize general-relativistic radiative transfer calculations that include effects from finite light travel time, plasmoid motion, particle acceleration, and synchrotron cooling and obtain a rich structure in the flare lightcurves. This model can naturally account for the observed motion of the bright regions observed by the GRAVITY experiment and the offset between the center of the centroid motion and the position of the black hole. It also explains why some flares may be double-peaked while others have only a single peak and uncovers a correlation between the structure in the lightcurve and the location of the flare. Finally, we make predictions for future observations of flares from the inner accretion flow of Sgr A* that will provide a test of this model.

Low field electron mobility in $α-Ga_{2}O_{3}$: An ab-initio approach

description: The $α$ phase of $Ga_{2}O_{3}$ is an ultra-wideband semiconductor with potential power electronics applications. In this work, we calculate the low field electron mobility in $α-Ga_{2}O_{3}$ from first principles. The 10 atom unit cell contributes to 30 phonon modes and the effect of each mode is taken into account for the transport calculation. The phonon dispersion and the Raman spectrum are calculated under the density functional perturbation theory formalism and compared with experiments. The IR strength is calculated from the dipole moment at the $Γ$ point of the Brillouin zone. The electron-phonon interaction elements (EPI) on a dense reciprocal space grid is obtained using the Wannier interpolation technique. The polar nature of the material is accounted for by interpolating the non-polar and polar EPI elements independently as the localized nature of the Wannier functions are not suitable for interpolating the long-range polar interaction elements. For polar interaction the full phonon dispersion is taken into account. The electron mobility is then calculated including the polar, non-polar and ionized impurity scattering.

description: In spite of the large lepton flavour violation (LFV) observed in neutrino oscillations, within the Standard Model, we do \textit{not} expect any visible LFV in the charged lepton sector ($μ\to e, γ$, $τ\to μ, γ$, etc.). On the contrary, the presence of new physics close to the electroweak scale can enhance the amplitudes of these processes. We discuss this in general and focus on a particularly interesting case: the marriage of low-energy supersymmetry (SUSY) and seesaw mechanism for neutrino masses (SUSY seesaw). Several ideas presented in this context are reviewed both in the bottom-up and top-down approaches. We show that there exist attractive models where the rate for LFV processes can attain values to be probed in pre-LHC experiments.
