IOT Based Pregnancy Women Health Monitoring System for Prenatal Care

In the developing countries most of the peoples are lived in the rural areas and medical systems are not amalgamated for sharing information. mostly, The pregnant women’s are unable to do their normal checkups at the starting time of pregnancy time and this cause higher death count in case of newborn and parental in the rural areas as well as in urban also. Due to this situation, the women’s are facing an immense medical issues. Accelerometer sensor is designed to measure the count of kicks/force by unborn child and it is transfer into the ARDUINO UNO controller. Motion of the foetal and some important parameters such as Blood pressure, Heartbeat rate, count of unborn child’s kicks and temperature for the women’s are measured using various types of sensors. The measured parameters are transmitted by way of IOT and it is displayed in the mobile phone. This system is highly sensitive and light weight even for small motion, so it is preferred as a home monitoring device. Now-a-days, ultrasound scanning method is used. Because it is long-term usage and very expensive. Limitations of ultrasound scan method on foetal are not completely clear. so ultrasound scan is not suggested continuous monitoring. Finally we used GSM module to calculate the normal and abnormalrate.
A Simulation-based Study on the Reliability of Data Center Upgrades

Reliability is a critical concern for data centers and has attracted extensive studies. Prior studies mostly focused on static data centers, assuming that the software and hardware components remain unchanged for a long time. However, today's data centers have to upgrade due to the increasing requirements of security, performance, or capacity, and it remains unclear how the data center upgrades affect data reliability. In this paper, we particularly focus on studying typical upgrading policies that are widely adopted in data centers and present a simulation-based study to reveal the effects of different policies on data reliability. We first design and implement an event-based reliability simulator called SIMDDC, which simulates different system organizations and failure/recovery models, and takes the probability of data loss ($PDL$) and the probability of data unavailability ($PUA$) as the metrics of reliability. By using SIMDDC, we then conduct a set of experiments. Based on our quantitative analysis of the experimental results, our study has revealed several interesting and important findings related to software and hardware upgrades in terms of upgrade domain settings, upgrade checks, and upgrade with different storage devices (HDDs and SSDs) and different data redundancy schemes. Our findings are helpful to determine proper upgrade policies while guaranteeing the data reliability in modern data centers. For public use, we have open sourced our simulator SMIDDC at http://github.com/yichuan0707/SIMDDC.
Enabling Write-Reduction Multiversion Scheme With Efficient Dual-Range Query Over NVRAM

Due to cyber-physical systems, a large-scale multiversion indexing scheme has garnered significant attention in recent years. However, modern multiversion indexing schemes have significant drawbacks (e.g., heavy write traffic and weak key- or version-range-query performance) while being applied to a computer system with a nonvolatile random access memory (NVRAM) as its main memory. Unfortunately, with the considerations of high memory cell density and zero-static power consumption, NVRAM has been regarded as a promising candidate to substitute for dynamic random access memory (DRAM) in future computer systems. Therefore, it is critical to make a multiversion indexing scheme friendly for an NVRAM-based system. For tackling this issue with modern multiversion indexing schemes, this article proposes a write-reduction multiversion indexing scheme with efficient dual-range queries. According to the experiments, our scheme effectively reduces the amount of write traffic generated by the multiversion indexing scheme to NVRAM. It offers efficient dual-range queries by consolidating the proposed version forest and the multiversion tree.
Experimental and Detailed Kinetic Modeling Study of Ethyl Pentanoate (Ethyl Valerate) Oxidation in a Jet Stirred Reactor and Laminar Burning Velocities in a Spherical Combustion Chamber

To improve our understanding of the combustion characteristics of ethyl pentanoate, a possible second generation biofuel, new experimental data were acquired for its oxidation kinetics in two complementary experiments. In a JSR (jet stirred reactor), concentration profiles of stable species were measured at 10 atm over a range of conditions (equivalence ratios of 0.6, 1, 2, fuel initial concentration of 1000 ppm, and temperatures between 560 to 1160 K). In a spherical combustion chamber, unstretched laminar burning velocities of ethyl pentanoate–air mixtures were measured at different pressures and temperatures and for equivalence ratios in the range 0.7–1.4. The oxidation of ethyl pentanoate was modeled using a new detailed kinetic reaction scheme (2719 reactions, 522 species). The chemical kinetic mechanism proposed here yielded good agreement with the present data. To interpret the results, reactions flux and sensitivity analyses were carried out.
Value addition, nutritional status and shelf-life of cocoa, cardamom and sugar free dietary fiber supplement

At present, supplementation of food is of great interest because of increasing nutritional awareness among the consumers. Supplementation with bengal gram is one way to meet the needs of dietary fiber particularly in convenient foods. Hence, an attempt has been made to develop value added dietary fiber supplement with acceptable sensory attributes. Three types of dietary fiber supplements, viz. cardamom flavor, cocoa flavor and sugar free flavor were developed. Cardamom flavor dietary fiber supplement was developed by the addition of bengal gram, fox nut, almonds, powdered sugar and cardamom powder at different levels. Cocoa flavor dietary fiber supplement was developed by the addition of cocoa powder with same ingredients whereas, the sugar free dietary fiber supplement was prepared without the addition of sugar with same ingredients. The nutritional and storage quality evaluation of the best accepted dietary fiber supplement were estimated. The findings indicated that cocoa flavor dietary fiber supplement prepared with bengal gram (25.6 g), fox nut (25.6 g), almonds (12 g) powdered sugar (28 g) and cocoa powder (8.8 g), cardamom flavor dietary fiber supplement with same ingredients at same ratio was best accepted, as compared to the sugar free dietary fiber supplement. Among the various types of dietary fiber supplements, cocoa flavor dietary fiber supplement was most accepted. There were significant increases in appearance, flavor, taste, over all acceptability and moisture; whereas, fat, total ash, crude fiber found to be constant. The developed dietary fiber supplement has a shelf-life of two and half months.
The Impact of Terminal Mobility on the Performance of a Panel-Based Large Intelligent Surface

A Large Intelligent Surface (LIS) is a recently pro-posed concept that relies on the integration of a vast number of antenna-elements over an entire surface able to transmit and/or receive information, especially suitable for high speed indoor communications and massive internet of things (IoT) applications. In this paper, we study the impact of terminal mobility on the performance of a panel-based LIS, considering different resource allocation approaches (including panel selection and/or panel-terminal association) and small panel areas. Such configuration represents a clear advantage in terms of flexibility, together with the fact that, from an economy of scale perspective, the production of this type of configuration choosing smaller areas seems more foreseeable.Our performance results show that there is no need to have a contagious distribution of panels, instead they can be physically separated according to a given distribution. It is also observed that, keeping a regularly fixed or predefined panel scheme, leading only to panel-terminal association, are able to fight against the unpredictability of terminal movements and overcome the computational complexity imposed by the optimum approach (that includes both panel selection and terminal-panel allocation stages), presenting maximum rate losses of 16−30%.
Sparse Code Multiple Access: Potentials and Challenges

The massive connectivity is among other unprecedented requirements which are expected to be satisfied in order to follow the perpetual increase of connected devices in the era of Internet of Things. In contrast to the family of conventional orthogonal multiple access schemes, the key distinguishing feature of non-orthogonal multiple access (NOMA) is its capacity to support the massive connectivity. Sparse code multiple access (SCMA) is one of the powerful schemes of code-domain NOMA (CD-NOMA) and is among the promising candidates of multiple access techniques to be employed in future generations of wireless communication systems thanks to the sparsity pattern of its codebooks. This technique has been actively investigated in recent years. In this paper, we provide a comprehensive survey of the state-of-the-art of SCMA. First, we will pinpoint SCMA place in the NOMA landscape including power-domain NOMA and CD-NOMA with the aim of justifying why SCMA is prominent. Then, its system architecture is highlighted and its basic principles are presented, afterwards a review of exiting codebook designs and available SCMA detectors is provided, before showing how resources are expected to be assigned, and how SCMA can be combined with other existing and emerging technologies. Finally, we present a range of future research trends and challenging open issues that should be addressed to optimize SCMA performance.
Mode Analysis by the Method of Auxiliary Sources With an Excitation Source

The method of auxiliary sources (MAS) is one of the numerical methods employed for the determination of the cutoff wavenumbers (eigenvalues) of cylindrical waveguides. According to the general scheme of MAS, the eigenvalues are obtained by requiring the square impedance matrix to be singular and therefore its determinant to be zero (or its condition number to be large). For large matrices, such computations are complicated and time-consuming. Additionally, these schemes are frequently contaminated with spurious eigenvalues. To overcome the difficulties, an efficient method based on MAS along with an excitation source has been proposed. The eigenvalues are obtained by measuring the physical response of the waveguide’s domain to this source; thus, an interior problem is always solved. This article is a comprehensive presentation of this method and its variants and aims to emphasize fundamental and often unfamiliar attributes. One of the main objectives is to show analytically and numerically that when an internal source is used, the eigenvalues are accurately computed without employing a regularization procedure. The method is applied to hollow simply and multiply connected waveguides with circular, elliptical, and rounded-triangular cross sections. The results are compared with those obtained from COMSOL Multiphysics. Moreover, the phenomenon of divergent and oscillating MAS currents—which may or may not occur depending on the relative position between the auxiliary curve and the excitation source—is discussed. It is emphasized that, with proper care, the phenomenon does not affect the accurate computation of the eigenvalues.

Zimbabwe in Covid-19 Lockdown: The Benefits and Shortcomings of Online Learning in Open Distance e-learning Institutions of Zimbabwe

: During the lockdown period for Covid-19, online learning has been the best platform to keep learners/lecturers engaged and safe by maintaining social distancing. Through online learning, students often face a number of challengesto their full participation in coursework units. The online environment also presents challenges for many academic staff that increasingly require higher levels of technological competency and proficiency on top of their regular academic workload. This study adopted the qualitative research paradigm in which a case study design was used. The design was considered appropriate because it enabled the researchers to interact with the participants in their natural settings on the phenomenon in its original form. The study was confined to Zimbabwe Open University, Bulawayo Regional Campus students and tutors only and it sought to establish the challenges learners experience in using the online learning platform during the Covid-19 lockdown. The findings show that participants still lack the knowledge on what online learning is all about and the different types of media used and how to use them in different environments.
Analysis of Porous Electrospun Fibers from Poly(l-lactic acid)/Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Blends

Solution blends of poly(l-lactic acid) (PLLA) and poly(3-hyroxybutyrate-co-3-hydroxyvalerate) (PHBV) in chloroform/DMF were electrospun at room temperature on a stationary collection plate. Polymer blend ratio, PHBV hydroxyvalerate content, solvent ratio, polymer concentration, and electrospinning process parameters were varied to determine optimal electrospinning conditions. The success of each formulation at producing nonwoven mats of continuous submicron diameter fibers was evaluated by optical and scanning electron microscopy. The diameter of the blend fibers was larger than electrospun fibers of either neat electrospun polymer, with a higher PLLA ratio favoring a porous surface morphology and higher PHBV ratios favoring beaded fiber morphology. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to analyze the thermal properties of the fibrous mats. The glass transition temperatures of the fibers from blends decreased as the PHBV weight ratio increased. The crystall.
FIJI SUGAR CORPORATION: A LEGITIMACY THEORY PERSPECTIVE

ABSTRACT The purpose of the study is to identify the strategies that Fiji Sugar Corporation Limited (FSC) has applied to receive Fiji Government’s ongoing financial support despite making continuous substantial losses over the years. Using a theoretical framework informed by legitimacy theory, the authors predict the strategies used by FSC. The study applied qualitative document analysis method and examined archival data such as scholarly articles, newspaper articles, and annual reports’ data for the periods covering from 2014 to 2018. The means of triangulation was challenging as interviews with the relevant participants were not possible due to Covid-19 pandemic and lockdowns. The findings of the study highlight that FSC has strategically utilized its existence and continuation to emphasize the economic and social dislocation its closure will create to the people of Fiji who depend on the sugar industry for their livelihood. This strategy has enabled FSC to receive Government’s continued support together with the unachievable promises that FSC is making all these years which is to improve its financial performances. The findings also suggest that FSC has smartly accepted its operational failures but has manipulated the cause of the failures beyond its control. The study contributes to the academic discussion on the strategies that an organization can adopt to maintain its legitimacy and continuation. Keywords: Legitimacy Theory; strategy; analysis; ongoing support; performance

Can Proper Strategic Planning Guarantee Its Implementation? A Case In A New District In A Developing Country

Strategic planning is highly recommended as one of the key factors that determine the success of the organization. However, only a few organizations succeed in implemented it. The research studied causes of poor strategy implementation. The study used Data collection techniques included previous research on factors that influence strategy implementation failures, and a survey of . three levels of managers in 38 agencies in the government. Using structural Equation Modelling-Partial Least Squares (SEM-PLS) as an analysis tool, results showed that stakeholder uncertainty, resources, and expertise are the major factors that influence the failure of strategy implementation. The finding provides an important explanation for poor strategy implementation performance in Batu Bara , which is a new district in Indonesia. One of the key policy recommendations is for the government to take measures toward enhancing the capacity of managers to manage stakeholders’ uncertainty.
Awareness on Radiation Protection Devices Among Dental Students

Radiation protection refers to the implementation of practices to reduce radiation exposure to patients, workers and the public. The fundamental aim of radiation protection is to reduce risk of harm by ensuring that any dose received is justified and as low as reasonably practicable‟ (ALARP). Exposure to Radiation has become common in Dentistry, patients are exposed to radiation by various radiation emitting devices such as OPG, CBCT,CT and IOPA. Apart from patients, dental surgeons and dental assistants are being exposed to radiations on a regular basis. Radiation effects on human cells cause various problems, increased risk of brain cancers, tumors of parotid gland and various problems in the head and neck region. Thus knowing about Radiation protection is important for both patients and Dentists.The Aim of this study is to create awareness and determine the understanding of radiation protection devices and its role in dentistry among dental students.Radiographic examination plays an important part of diagnosis in dental practice.Majority of the dental students within the study were aware of the radiation protection devices and its usage.

Country-of-Origin Image and Its Effect on Purchase Intention: A Study on a Chinese Smartphone Brand

Previous research examining the influence of country-of-origin image on purchase intention have indicated inconsistent results. China, as the largest global business players in the world have secured a lot of its brands as the world’s market leaders. This research aims to examine how China, as the country of origin of Huawei smartphone, has been perceived by the Indonesian consumers. This study also aims to examine whether its country-of-origin image could influence Huawei’s perceived quality, brand image, which in turn, affecting consumers’ intention to purchase the product. Online survey was completed to 226 respondents using purposive sampling technique. The collected primary data was analysed using PLS-SEM technique. The findings of the study showed that, directly, country-of-origin image variable had no significant effect on purchase intention. In other words, country-of-origin image alone was not strong enough to stimulate consumers to buy the smartphone product. Research result also revealed that the role of brand image was stronger that perceived quality in mediating the effect of country of origin image on purchase intention. In fact, brand image, appeared as the significant mediating variable of how country of origin image influenced purchase intention.
