Cloud Based IoT Architecture

CLOUD BASED IOT ARCHITECTURE by Nathan Roehl The University of Wisconsin-Milwaukee, 2019 Under the Supervision of Professor Tian Zhao The Internet of Things (IoT) and cloud computing have grown in popularity over the past decade as the internet becomes faster and more ubiquitous. Cloud platforms are well suited to handle IoT systems as they are accessible and resilient, and they provide a scalable solution to store and analyze large amounts of IoT data. IoT applications are complex software systems and software developers need to have a thorough understanding of the capabilities, limitations, architecture, and design patterns of cloud platforms and cloudbased IoT tools to build an efficient, maintainable, and customizable IoT application. As the IoT landscape is constantly changing, research into cloud-based IoT platforms is either lacking or out of date. The goal of this thesis is to describe the basic components and requirements for a cloud-based IoT platform, to provide useful insights and experiences in implementing a cloud-based IoT solution using Microsoft Azure, and to discuss some of the shortcomings when combining IoT with a cloud platform.
Improved Quantification of Global Mean Ocean Mass Change Using GRACE Satellite Gravimetry Measurements

Global mean ocean mass change derived from the Gravity Recovery and Climate Experiment (GRACE) gravity solutions generally agrees well with ocean mass change inferred from satellite altimeter sea surface height and Argo floats observations during the period January 2005 to December 2015. However, there is a systematic annual phase lag (~10°) between GRACE and Altimeter‐Argo estimates. This phase lag is attributed to the enforced mass conservation in GRACE gravity solutions, in which the ΔC00 coefficients (representing changes in total Earth mass) are set to zero. After a correct implementation of global mass conservation by removing global mean atmospheric mass from the GRACE solutions using atmospheric model predictions, the annual phase lag is nearly completely gone, yielding significantly improved agreement between GRACE and Altimeter‐Argo estimates. In addition, retaining GRACE ΔJ2 coefficients provides better GRACE ocean mass estimates at both seasonal and long‐term time scales.
The Effect of Emotional Freedom Technique Therapy on Nurse Burnout

Burnout can develop as a result of long work stress and cause a change in attitudes and behaviors withdrawing psychologically. The most visible impact of burnout is the decline in performance and quality of service. As a result, they were unable to fulfill the work demands and finally decided not to attend, increasing rates of sick leave, reduced work effectiveness or even leaving their jobs. This study aims to determine the effect of Emotional Freedom Technique (EFT) therapy on burnout in implementing nurses. The design of this study uses quasi-experimental design with control group. The sample in the study were 38 nurses, divided into 2 groups, each group consisting of 19 people selected through purposive sampling. This study used the Wilxocon Signed Rank Test to determine the differences in one pre-post group and the Mann Whitney Test to analyze changes after two different post-post groups. The results showed the value of p value in the treatment group = 0,000 which means that there was an effect of therapy (EFT) on burnout in the implementing nurses, whereas in the control group there was no difference with the p value = 0.925, the p value was influenced by EFT therapy (Emotional Freedom Technique ) towards burnout of nurse nurses before and after in groups of 0,000. It is expected that the Hospital can overcome burnout by passing EFT therapy.
A Thematic Analysis exploring the Impact of Social Media Use on Romantic Relationships

Whilst research considers the role played by social media in romantic relationships (Van Ouytsel et al., 2016; Vaterlaus et al., 2016), little focuses on potential positive impacts or opinions from sexual minority relationships. Thus, existing research may have provided limited findings into the impact of social media use on relationships. The present research aimed to explore the positive and negative impacts of social media use on romantic relationships, using semi-structured interviews of eight participants. Responses were analysed using thematic analysis in which three themes were formed: interpretation of online actions, digital trace surveillance, and formation and maintenance of romance. Findings suggest that the impact of social media can be both positive and negative, and thus, may affect the maintenance of romantic relationships. Furthermore, future recommendations were discussed, including the suggestion of dyadic interviews to obtain a deeper comprehension of the impact on both partners.
Corporate Scandal Spillovers: An Empirical Study of the Dieselgate Using Twitter Data

We explore how the social media attention received by a firm implicated in a large corporate scandal affects the market value of its competitors. Existing work provides contrasted arguments and evidence regarding the spillover effects of scandals: rivals may suffer from contamination and at the same time benefit from substitution. Building on and extending prior work, we develop a stylized model to predict how contamination and substitution interact and jointly affect firms’ value in a non-linear way during the course of a scandal. We test our model using unique data, including 1.2m tweets, on the Dieselgate scandal that affected the global automobile industry in 2015. We find evidence of an inverted-U shape relationship between social media attention and rival firms’ value at the global scale, suggesting that substitution dominates on average. Yet the pattern is reversed for German and other European firms, primarily affected by contamination. We discuss how the study contributes to the literature on corporate scandal and disapproval, with implications for the understanding of the impact of social media on organizations.
Characterizing Recurrence Following Hybrid Ablation in Patients With Persistent Atrial Fibrillation.

Purpose It is widely accepted that atrial fibrillation (AF) accounts for half of arrhythmia recurrences following endocardial catheter ablation of AF. An epicardial-endocardial approach (hybrid) has emerged as an alternative to endocardial ablation alone for the treatment of AF, yet recurrence after a hybrid procedure has not been well characterized. This retrospective study is aimed at characterizing recurrence following hybrid ablation for patients with persistent AF. Methods Patients with persistent AF (N=108) received both endocardial and epicardial ablation of the posterior left atrial wall using catheter ablation and a small midline surgical approach (hybrid). Presence of atrial flutter or AF was determined with ambulatory monitoring (n=22) or electrocardiogram analysis (n=86) at each follow-up visit. Recurrence mode was confirmed by electrophysiology study for those patients undergoing subsequent catheter ablation after hybrid ablation. Results Patients were followed for a mean ± standard deviation of 25 ± 14 months. Of patients who had a recurrence, 53% (n=33) were in atrial flutter and 47% (n=29) were in AF. Of those who had a recurrence with atrial flutter, 14 received repeat ablation for either left (n=11) or left/right (n=3) atrial flutter and 3 received AF ablation. Half of ablations for atrial flutter recurrence following the hybrid procedure involved the mitral isthmus. Conclusions Atrial flutter accounts for about half of arrhythmia recurrences post-hybrid ablation. If catheter ablation of the mitral isthmus is considered during the hybrid procedure to prevent subsequent occurrence of perimitral flutter, bidirectional block must be performed to ensure a complete line of block.
Diagnostic value of mean platelet volume (MPV) to troponin T inpatients with acute coronary syndrome

Acute Coronary Syndrome (ACS) is used to describe the spectrum of coronary artery disease (CAD). Troponin T is the determinant of the most sensitive marker of ACS, but there aren’t all hospitals have this because of expensiveness. Mean Platelet Volume (MPV) is one of the components of a complete blood routine examination and relatively cheap as a marker in ACS. Determining the sensitivity and specificity of MPV in detecting cases of the acute coronary syndrome, 325 subjects’ medical records were from the period of July 2013 to June 2014; 228 ACS patients met the inclusion criteria. 228 subjects showed a risk factor for age ≥45years of more 195 (85.5%). 122 subjects with hypertension (53.5%) and subjects who smoked 118 (51.8%) that suffered most ACS. Subjects with risk factors for diabetes mellitus, obesity, menopause and dyslipidemia in this study was lower than non-diabetic 161 (70.6%), obese189 (82.9%), nonmenopause 196 (86%) and normal lipid 210 (92.1%). But there was norelation between risk factor with MPV and troponin T statistically. The results of diagnostic tests MPV for the evaluation of patients with ACS, sensitivity 92%, specificity 71%, positive predictive value 95% and negative predictive value 58%.
Between Evidence and Representation: A New Methodological Approach to the History of Performance Art and Its Documentation

Early accounts of the history of performance art, such as the influential Performance: Live Art 1909 to the Present by RoseLee Goldberg, have tended to categorize all twentieth-century performance and action-based works of art as part of the broad category of ‘performance art’. Many heterogeneous phenomena have been gathered under this single label, while discontinuities and differences within the development of live and bodily art practices in the twentieth century have been downplayed or neglected. The most recent historiography has rejected the attempt to provide a linear and all-encompassing history of performance art and has instead preferred to investigate its histories in different geographical, political, and cultural contexts. This has led to publications of great interest, such as Amy Bryzgel’s Performance Art in Eastern Europe since 1960, or the collections Live Art in LA: Performance in Southern California 1970–1983, edited by Peggy Phelan, and Performance Art in Ireland: A History, edited by Áine Phillips. However, despite these histories’ plurality, they all address a single epistemic object – they are histories of ‘performance art’. Crucial questions remain unanswered: what makes these individual histories part of a common framework called ‘performance art’? What exactly is ‘performance art’? The diversity of works indicated with this term – ranging from live actions performed for an audience to works designed specifically for photographic record – has made answers to these questions provisional and partial. Whenever the features of the medium performance are supposed to be what links these artistic practices together, examination 1. Rose Lee Goldberg, Performance: Live Art 1909 to the Present (London: Thames & Hudson, 1979). Goldberg uses here, as do many scholars later, ‘performance art’ and ‘live art’ as synonyms. Others, instead, use ‘live art’ in relation to the particular history of this term in the UK since the 1980s; see, for example, the special issues of Contemporary Theatre Review on ‘Live Art: Definition and Documentation’, 2, no. 2 (1994); and ‘Live Art in the UK’, 22, no. 1 (2012). In this article, I refer only to ‘performance art’, as I am interested in examining the disciplinary history specifically related to this term.
Blood Transfusions for Emergency Laparotomies in General Surgery

J Acute Care Surg Vol. 7 No. 1, April 2017 Correspondence to: Vignesh Narasimhan, FRACS Department of General Surgery, Frankston Hospital, Peninsula Health, 2 Hastings Road, Frankston 3199, Melbourne, Australia Tel: +61-3-9076-2000 Fax: +61-3-9076-3902 E-mail: vignesh.naras@gmail.com Purpose: Decisions regarding perioperative blood transfusions are subject to clinical and laboratory factors. Blood transfusions are associated with increased risk of infection, sepsis, organ failure, and length of stay. Current guidelines on transfusions are based on elective settings. There is a paucity of data on blood transfusion use in emergency surgery. This study reviews the appropriateness of blood transfusions in patients undergoing emergency general surgical laparotomies. Methods: Patients undergoing emergency general surgical laparotomies at Peninsula Health from January 2013 to May 2015 were reviewed. Hemoglobin (Hb) levels triggering transfusion and overall blood utilization were obtained. Transfusions were classified based on whether they were given pre-, intraor postoperatively. Transfusions with Hb >80 g/L in the absence of bleeding or preoperative anemia were deemed ‘inappropriate’ as per Australian Blood Authority guidelines. Results: Over the 29-month period, 368 patients underwent 398 emergency laparotomies. Blood transfusions were given to 102 patients (27.7%). These patients required 240 transfusion episodes. Patients were given a median of three units of blood. One hundred and sixty-six transfusions (69.2%) were postoperative. Forty-six transfusions (19.2%) were given with Hb >80 g/L in the absence of other indications, and were deemed inappropriate. Inappropriate transfusions occurred more frequently on the ward compared to ICU (p<0.05). Almost two thirds of inappropriate transfusions were given for Hb 80∼85 g/L. Conclusion: Nearly one in five patients received an inappropriate transfusion. More judicious use of blood products in emergency patients is required, especially on surgical wards.

Effect of Bilateral Lateral Rectus Recession in Intermittent Exotropia according to the Limbus Insertion Distance

Purpose: The aim of this work was the evaluation of the effect of the limbus insertion distance (LID) of the lateral rectus on the surgical results of bilateral lateral rectus recession in intermittent exotropia (IXT) in children and adults. Patients and Methods: This retrospective study included 76 patients. The patients were divided into two groups: group I (age 5 - 13 y), group II (>13 y). All the patients had basic type of intermittent exotropia (IXT) and all of them underwent bilateral lateral recessions according to the preoperative angle of deviation. Intraoperatively, the distance of limbus insertion was measured by surgical calipers. The dose response effect was calculated as the difference between the preoperative angle and postoperative angle divided by total amount of recession and cases were followed at 1 month, 3 months, 6 months and 12 months postoperative. Results: The mean LID in group I was (6.2 ± 0.61 mm) and (6.1 ± 0.55 mm) in group II. The mean dose response (MDR) at 1 year postoperative was (2.32 ± 0.25 mm) in group I and (2.26 ± 0.23) in group II. In patients with LID 6.25 mm who had larger mean dose response (2.52 ± 0.15). There was a significant positive correlation between the LR muscle LID and the dose-response effect. Conclusion: There is positive correlation between the LID of the LR muscle and the recession effect in bilateral lateral rectus recession in treatment of IXT.
The role of customer engagement facets on the formation of attitude, loyalty and price perception

This study aims to investigate the influence of customer satisfaction on four facets of customer engagement: customer influencer behavior, knowledge behavior, referral behavior and purchase behavior. Furthermore, its (in)direct influence on affective attitude, price perception and loyalty is investigated. ,Two studies were conducted. First, an experimental scenario design was set up to investigate the hypothesized relations between customer engagement; customers’ affective attitude and their loyalty; and their price perceptions. Second, a survey at a national forest park center helped to secure external validity. ,The results indicate that engaged customers develop a more positive affective attitude, which leads to increased future loyalty and positive price perceptions. In addition, the results suggest that assessing cognitive approaches exclusively is not sufficient for understanding customers’ price perceptions. ,Future research should investigate antecedents of customer engagement behaviors (CEBs) other than satisfaction, and extend this research by taking into account further mediators that might be cognitive rather than affective. ,The results are of superior importance for services or tourism destinations. Fostering CEB can help in improving a destinations’ performance. ,This research expands the current state of literature by investigating several dimensions of CEB at one time, as well as by examining customers’ affective attitude toward the organization as a potential mediator, extending previous research approaches.
Patterns of Parliamentary Opposition: Empirical Evidence from the Deliberations in the German Bundestag’s Committee on European Union Affairs

This article examines patterns of oppositional behaviour in the German Bundestag’s Committee on European Union Affairs (EAC) for two separate legislative periods (2005–2009 and 2009–2013). The study makes two contributions to previous research. It, first, shed some much-needed empirical light on political opposition in the Bundestag by examining how much and what kind of opposition exists in the German EAC. Secondly, the article examines the differences in oppositional behaviour of the Members of Parliament between the two legislative periods following an institutional reform in 2009 that afforded the Bundestag with increased opportunity structures in Europen Union affairs.
Improving Main-memory Database System Performance through Cooperative Multitasking

Database systems access memory either sequentially or randomly. Contrary to sequential access and despite the extensive efforts of computer architects, compiler writers, and system builders, random access to data larger than the processor cache has been synonymous to inefficient execution. Especially in the big data era, data processing is memory bound, and accesses to DRAM and non-volatile memory each take several tens or hundreds of nanoseconds respectively, posing a great challenge to current processors. Due to the mismatch between the way humans write code and the way processors execute this code, workload execution stalls on main memory access, instead of executing the other parallel work that typically exists in big data workloads. This thesis establishes cooperative multitasking as the principal way to hide memory latency in operations that consist of parallel tasks. We first systematize cooperative multitasking presenting an analogue of Amdahl’s law for latency hiding. More importantly, we then introduce interleaving with coroutines, a general-purpose and practical technique to interleave the execution of parallel tasks within one thread interleaved execution and thereby hide memory access. This form of cooperative multitasking enables significant performance improvements for analytical and transactional use cases that suffer from unavoidable memory accesses, such as index joins and tuple reconstruction, as well as concurrent GET and PUT operations in key-value stores. Given enough parallel work, sufficient hardware support for concurrent memory accesses, and a lowoverhead mechanism to switch between tasks, interleaved execution renders important database operations oblivious to memory latency and makes their execution behave as if all accessed data resides in the processor cache.
Changes in the frequency of hot, humid days and nights in the Mississippi River Basin

The severe impacts of climate change on human health will rise from the co‐occurrence of extreme humid and hot conditions. In this study, six indices associated with high humidity, maximum and minimum daytime and nighttime temperature and the heat index (HI) values were analysed to assess temporal changes in hot, humid conditions in the Mississippi River Basin (MRB), USA, for the period 1948–2017. The frequencies of extreme humid days and nights have significant upward trends over 97 and 93% of MRB, respectively. Trends of day‐time HI were mainly upward (63%), except for eastern regions of MRB. More of the upward trends for the frequency of hot nights were significant than the trends for hot days either for the entire period (72% of MRB for hot nights and 4% for hot days) or after a significant change‐point (26% of MRB for hot nights and 20% for hot days). Except for minimum HI, other indices including extreme maximum and minimum temperature and specific humidity as well as maximum HI had an upward trend after the 1980s and 1990s for the majority of grid‐cells. Central and southern areas of the MRB were identified as regions most at risk for an extreme HI value during both days and nights.
Anti‐inflammatory effect from extracts of Red Chinese cabbage and Aronia in LPS‐stimulated RAW 264.7 cells

Abstract A chronic inflammatory environment facilitates tumor growth and proliferation. Fruits and vegetables are important sources of anthocyanins, polyphenols, and other biologically active substances that can favorably affect the pathogenesis of cancer. The objective of the study was to investigate the anti‐inflammatory effects of Red Chinese cabbage (RC) and mixture of commercial Red Chinese cabbage leaves and Aronia fruits (ARC) in LPS‐stimulated RAW 264.7 cells. The RAW 264.7 cells were cultured and measured the cytotoxicity by using an MTT assay. The inflammatory markers, such as nitrite, IL‐6, and TNF‐alpha expression, were evaluated using ELISA, and protein expression of inflammatory markers like iNOS and COX‐2 was analyzed using Western blot. MTT assays showed that pretreatment of RAW 264.7 cells with RC and ARC did not change cell growth or cytotoxicity. We also found that ARC extracts reduced inflammation‐related biomarker (TNF‐a, IL‐6, and NO) production and gene expression (iNOS, COX‐2). Our results suggested that ARC has good anti‐inflammatory properties compared with RC that maybe used as potential nutrients for treating inflammatory diseases.
Blood Donation Practices of Tertiary Level Students in South Eastern Nigeria: Prevalence and Determinants

Introduction: Safe and adequate blood donation is critical in saving millions of lives annually. In many developing including Nigeria, there is paucity of blood donors. Aim: In this study, we assessed the blood donation practices of tertiary level students in Imo State, South East Nigeria as well as its prevalence and determinants. Methodology: Multistage sampling technique was used. Stage one involved the stratification of the institutions into universities and non-universities. In stage two, one university and one non university was selected using simple random method. Stage three involved the selection of study participants from the student registry using systematic sampling method. Self-administered Original Research Article Duru et al.; IBRR, 10(2): 1-12, 2019; Article no.IBRR. 53461 2 questionnaire was the study instrument. Data analysis was with Statistical Package for Social Sciences (IBM – SPSS) version 20. Results: Six hundred (600) undergraduates participated in the study. The mean age of the respondents was 21.3 ± 5.0 years. The one year prevalence of blood donation in this study was 13.8% and 63.1% of the non-donors were willing to donate. Respondents aged 15 – 29 years more willing to donate blood compared to those aged 30 – 44 years (OR = 3.03, p = 0.0003), those that were single were 4 times more willing to donate in comparison to those that were married/divorced (OR = 4.02, p < 0.0001). Respondents that were of Catholic faith were also more willing to donate compared to those that were of Pentecostal/Orthodox denomination (OR = 2.72, p = <0.0001). Class distribution and residence were not independent predictors of willingness to donate blood. Conclusion: From the findings in this study, it was obvious that the willingness to donate blood is far greater than the actual act of donating blood. There is need to continue to reach out to those willing to donate but do not know how to go about it.
