Published: October 2019

In this research an internet of things (IoT) system is designed for the purpose of industrial environment monitoring and control. The system is mainly composed of control and sensor units. Control unit has the responsibility of managing the received data form the sensor unit and then executing the developed control algorithm based on the measured parameters. NodeMCU development kit is used as the core of the control unit. The senor unit contains gas and temperature sensors utilized for measuring the temperature and concentration of toxic gases in the monitored space. A buzzer has also been embedded in the sensor unit for alerting the occupants acoustically in the danger situations. If the monitored temperature gets higher or lower than the set levels, the air conditioning system will be automatically operated. Similarly, the fan (ventilation) system will be operated if the level of toxic gases becomes high. A mobile application, based on Blynk platform, is then developed to enable the wireless monitoring and control of the environment by the in charge people. In addition to the automatic and wireless control the manual control capability is considered in the developed IoT system.
An implementation of optimal control methods (LQI, LQG, LTR) for geostationary satellite attitude control

Published: October 2019

<p>This paper investigates a new strategy for geostationary satellite attitude control using<strong> </strong>Linear Quadratic Gaussian (LQG), Loop Transfer Recovery (LTR), and Linear Quadratic Integral (LQI) control techniques. The sub-system satellite attitude determination and control of a geostationary satellite in the presence of external disturbances, the dynamic model of sub-satellite motion is firstly established by Euler equations. During the flight mission at 35000 Km attitude, the stability characteristics of attitude motion are analyzed with a large margin error of pointing, then a height performance-order LQI, LQG and LTR attitude controller are proposed to achieve stable control of the sub-satellite attitude, which dynamic model is linearized by using feedback linearization method.<strong> </strong>Finally, validity of the LTR order controller and the advantages over an integer order controller are examined by numerical simulation. Comparing with the corresponding integer order controller (LQI, LQG), numerical simulation results indicate that the proposed sub-satellite attitude controller based on LTR order can not only stabilize the sub-satellite attitude, but also respond faster with smaller overshoot.</p><p> </p>

<p><span>In recent days, IoT has been widely accepted and WSN (Wireless Sensor network) is being used for variety of the applications such as transportation, medical, environmental, military, it moreover the main aim to deploy the WSN is to collect the data about the given set of phenomena. The common task of WSN is to sense the data and send over the network. Moreover, due to the various purpose such as statistical analysis, the data aggregation is required. <span> </span>However, the when the dynamic network topology is considered, it is considered to be the very difficult task to provide the secure and efficient data aggregation. The main issue here is to ensure the security and accuracy of the data aggregation. Hence, in this research we have proposed an algorithm named as E-SDA (Efficient Secure Data Aggregation) in order to provide the secure data. In this, the algorithm provides the flexibility to detect the dishonest honest through neighbor monitoring. Later, extensive simulation has been done in order to prove the convergence of our algorithm.</span></p>

The cumulative number of historical and recent power system outages substantiates the fact that further studies are necessary for an improved solution to the issue of voltage instability on the grid and the subsequent system collapse. Voltage collapse is a serious reliability issue which inhibits the objective of running a reliable and secure power system network. In this study, a new line stability index (NLSI_1) for predicting voltage collapse is presented. The new index considers a switching logic which is derived from the difference of voltage angle between the two load buses. The index is deployed for performance analysis using the 28-bus, 330-kV Nigeria National Grid (NNG). The simulation implemented in MATLAB shows that the index gives the same results as Line stability index (Lmn) and Fast Voltage Stability Index (FVSI) indices. The base case and the contingency scenarios were considered during the simulation. The base case analysis using the NNG values of all the three indices FVSI, Lmn, and NLSI_1 for simulation generates a value less than one for the entire lines which implies that the NNG is stable in this mode. The values of the three indices are almost the same, which confirms the accuracy of the novel index developed. The analysis for the contingency case reveals that the load bus 16 (Gombe) which has the lowest, maximum permissible reactive load of 139.5MVAR is the weakest; also power line 16-19 is identified as the critical line. The result of the simulation confirms that the accuracy was improved by using NLSI_1.
Automatic segmentation of wrist bone fracture area by K-means pixel clustering from X-ray image
Authors: Kim Kwang Baek , Song Doo Heon , Yun Sang-Seok 
Published: October 2019

Early detection of subtle fracture is important particularly for the senior citizens’ quality of life. Naked eye examination from X-ray image may cause false negatives due to operator subjectivity thus computer vision based automatic detection software is much needed in practice. In this paper, we propose an automatic extraction method for suspisious wrist fracture regions. We apply K-means in pixel clustering to form the candidate part of possible fracture from wrist X-ray image automatically. This method can recover previously detected patterned false cases with edge detection method after fuzzy stretching. The proposed method is successful in 16 out of 20 tested cases in experiment.

Published: October 2019

Cognitive radio networks (CRNs) play an important role in wireless communications which have the ability to significantly utilize the spectrum that not in used and reduce the current spectrum scarcity. CR allows unlicensed users (secondary users) to occupy the licensed spectrums without causing interference with licensed users (primary users). This can be achieved smoothly through four main CR procedures: spectrum sensing, spectrum decision, spectrum sharing, and spectrum mobility. In this paper, we propose an intelligent spectrum handoff (SH) scheme based on multiple attributes decision making. The handoff decision depends on three considered parameters: received power, traffic load and arrival rate of the primary users. The simulation results show the proposed scheme outperformed the conventional scheme by reducing the probability of SH which leads to improve system performance.

Authors: Pungus Stenly Richard , Yahaya Jamaiah Haji , Deraman Aziz , Bakar Noor Hasrina Binti 
Published: October 2019

This paper introduces a framework for data modeling to support ubiquitous computing based on context-awareness. Data always grow in term of volume, variety, velocity, and value. The problem arises when it grows exponentially. Consequently, data is anywhere and requirements change in early data definitions then data design become not as the plan. Therefore, suitable approach with new paradigm and methods of data modeling needs to be enhanced to solve the problems in the real world. Data model must consider the active object that related to each other. Any objects may interact with each other in a ubiquitous way and recorded in digital technology. Sensors, actuator devices, and radio frequency identification technology may support communication between objects through ubiquitous computing. The data model in Ubiquitous Computing needs to restructure to become active and dynamic. Ubiquitous computing is a model that enable all objects around the people to communicate and invisible. In order to support this paradigm, a new perspective of how data are designed and stored on each object is needed. Furthermore, using ubiquitous computing, the pervasive network can request and response information, which means the devices may communicate and has the initiative to solve a problem without human intervention. Human wants more intelligence objects. Therefore, more sensors and memory are required. Data structures need to enhance or embedded into any devices that interact with the human.

A resolução nº 510, do Conselho Nacional de Saúde, de 7 de abril de 2016, no capítulo V, artigo 24º, estabelece que as etapas preliminares ao campo não precisam ser aprovadas por comitê de ética, mas devem primar pela avaliação da viabilidade para a realização da pesquisa. Entretanto, muitos pesquisadores não estão cientes da existência desta etapa, ou de suas características. O presente artigo procura exemplificar a importância desta etapa preliminar de campo para a modelagem da problemática, da axiomática e dos caminhos metodológicos de um projeto de pesquisa relacionado à temática de resistência das integrantes da Associação de Mulheres de Vila Canoas e Pedra Bonita às representações oblíquas e estigmatizadas dos que adentram a favela de Vila Canoas para realizar registros dos moradores locais em suas esferas ou espaços íntimos, pessoais, sem prévia autorização, a partir de ângulos parciais ou distorcidos – especialmente graças ao turismo de favela. Para a estruturação deste artigo e comprovação da validade desta etapa preliminar, relata-se a visita preliminar à comunidade que serviu de campo para esta pesquisa. Para além da visita, ocorreram conversas com uma das lideranças locais. As conversas transcorreram livres de conjecturas ou registros, uma vez que a ideia era averiguar as condições necessárias à realização da pesquisa.
The Pope, the Poor, and the Role of Religion in Argentina’s Public Sphere
Authors: Gustavo Morello S.J. 
Published: October 2019

Pope Francis’s public statements about and criticisms of the global economic system and local politics present an opportunity to explore how ordinary people react to the presence of a religious voice in the public sphere. Data on people’s perceptions of the pope’s interventions collected from semistructured nonrandom interviews with 41 low-income Argentines of various religious orientations reveal that they identified and regulated the boundaries of religion in the public sphere with different criteria from those that secularists would expect. Respondents assumed that religion and politics shared the space of power and therefore accepted the pope as a political actor. However, they considered it legitimate for him to intervene only when he stood for the poor, promoted human brotherhood, and exemplified God’s love. Religion was welcome where modernity had failed. Las declaraciones públicas del Papa Francisco y las críticas al sistema económico global y la política local presentan una oportunidad para explorar cómo la gente común reacciona ante la presencia de una voz religiosa en la esfera pública. Los datos sobre las percepciones de las personas sobre las intervenciones del Papa recopiladas de entrevistas semiestructuradas no aleatorias con 41 argentinos de bajos ingresos de diversas orientaciones religiosas revelan que identificaron y regularon los límites de la religión en la esfera pública con criterios diferentes de los que los laicistas esperarían. Los encuestados asumieron que la religión y la política compartían el espacio de poder y, por lo tanto, aceptaron al Papa como actor político. Sin embargo, consideraron legítimo para él intervenir solo cuando defendió a los pobres, promovió la hermandad humana y ejemplificó el amor de Dios. La religión era bienvenida donde la modernidad había fallado.
Pensions and Commodification under the PT Governments (2003–2015)
Authors: Andrietta Lucas Salvador , Lemos Patrícia Rocha , Fagnani Eduardo 
Published: October 2019

An analysis of the development of the Brazilian pension system’s issues under the Partido dos Trabalhadores (Workers’ Party—PT) governments focused on four main themes: austerity policy, payroll tax exemptions for employers, expansion of supplementary pensions, and union strategies associated with pension funds. The way the PT governments acted in these areas, despite expressing a different arrangement of interests from those of previous administrations that were self-declared neoliberal, did not change the general course of the commodification of social policy. Uma análise da evolução da questão previdenciária durante os governos do Partido dos Trabalhadores destaca quatro temas principais: o ajuste fiscal permanente, as desonerações da folha de pagamento para empregadores, a expansão da previdência complementar e a estratégia sindical ligada aos fundos de pensão. A atuação governamental nessas questões não alterou o sentido geral do processo de mercantilização, apesar de expressar uma acomodação de interesses distinta dos governos anteriores, declaradamente neoliberais.
Architectures of millennial development: Entrepreneurship and spatial justice at the bottom of the pyramid in Cape Town
Authors: Pollio Andrea 
Published: October 2019

In Cape Town, as in other cities of the Global South, the paradigms of millennial development are continuously mobilized in specific material ways. The idea that poverty can be fought with profit is manifest in a series of urban experiments that involve informal entrepreneurs, corporations, real estate developers, local architects, economists, non-governmental organizations and state agencies, in the search for market solutions to economic marginality. To illustrate this argument about the spatial politics of development, this paper charts the architectural, organizational and pedagogical making of Philippi Village, a building complex in one of Cape Town’s poorest neighbourhoods. A former cement factory turned into an entrepreneurial hub, Philippi Village is a material inscription, at the so-called bottom of the pyramid, of the possibility of expanding the frontiers of accumulation. However, while this entrepreneurial village may be a brownfield site for new forms of profit, its architectures also reveal the diverse economic rationalities that emerge from the quest of good entrepreneurship, including the politics of seeking spatial justice amid the urban legacies of apartheid.
Migraine-associated gene expression in cell types of the central and peripheral nervous system
Authors: Vgontzas Angeliki , Renthal William 
Published: October 2019

Background Genome-wide association studies have implicated dozens of genes with migraine susceptibility, but it remains unclear in which nervous system cell types these genes are expressed. Methods Using single-cell RNA sequencing data from the central and peripheral nervous system, including the trigeminal ganglion, the expression of putative migraine-associated genes was compared across neuronal, glial and neurovascular cell types within these tissues. Results Fifty-four putative migraine-associated genes were expressed in the central nervous system, peripheral nervous system or neurovascular cell types analyzed. Six genes (11.1%) were selectively enriched in central nervous system cell types, three (5.5%) in neurovascular cell types, and two (3.7%) in peripheral nervous system cell types. The remaining genes were expressed in multiple cell types. Conclusions Single-cell RNA sequencing of the brain and peripheral nervous system localizes each migraine-associated gene to its respective nervous system tissue and the cell types in which it is expressed. While the majority of migraine-associated genes are broadly expressed, we identified several cell-type-specific migraine-associated genes in the central nervous system, peripheral nervous system, and neurovasculature. Trial registration: not applicable.

Background: Physical activity is recommended for kidney transplant recipents as it may improve outcomes including mortality, exercise capacity, muscle strength, and health-related quality of life. Objective: The objective of this study was to examine accelerometer-based physical activity and sedentary time profiles among kidney transplant recipients and examine possible demographic and clinical correlates of physical activity and sedentary time. Design: Cross-sectional. Setting: Edmonton, Alberta, Canada. Patients: Kidney transplant recipients were recruited (N = 1,284) from the Northern Alberta Renal Program’s Nephrology Information System database (1993-2016). Measurements: Participants wore an ActiGraph GT3X+ accelerometer on their hip during waking hours for seven consecutive days. Methods: Kidney transplant recipients (1993-2016) recruited from the Northern Alberta Renal Program’s Nephrology Information System database wore an accelerometer and completed a self-reported questionnaire. Multiple linear regression was used to determine associations between activity level, demographic, and clinical characteristics. Results: Participants’ (n = 133; 11% response rate) mean age (SD) was 58 (14) years and 56% were female. Mean total sedentary time was 9.4 (1.4) hours per day; total moderate-to-vigorous physical activity (MVPA) time was 20.7 (19.6) minutes per day. MVPA was significantly associated with age where each additional year was associated with 0.48 fewer min/day (ie, ~30 seconds) (unstandardized beta: B = −0.48 min/day, 95% confidence interval [95% CI]: −0.75, −0.22). Sedentary time was significantly associated with age ( B = 1.0 min/day, 95% CI: 0.03, 1.9), body mass index ( B = 2.7 min/day, 95% CI: 0.2, 5.13), education ( B = 39.1 min/day, 95% CI: 12.3, −65.8), and inversely associated with income ( B = −44.9 min/day, 95% CI: −73.1, −16.8). Limitations: Limitations include the cross-sectional design, poor response rate, and limited generalizability of the results. Conclusions: Kidney transplant recipients showed high volumes of sedentary time and low volumes of health-enhancing physical activity. Understanding correlates of these behaviors may aid in the development of interventions to favorably change these behaviors.

Background: Rotator cuff tear is a common disease for middle-aged and elderly patients, and relatively good postoperative outcomes have been reported in the literature. The aim of the study was to examine cases that underwent miniopen rotator cuff repair and to clarify their long-term clinical and imaging outcomes. Methods: A total of 68 patients who underwent a miniopen repair for small- to medium-sized rotator cuff tears with good cuff integrity and without retear on magnetic resonance imaging (MRI) at 1 year postoperatively were followed up for a minimum of 10 years (mean ± standard deviation: 11.4 ± 1.2 years) and analyzed retrospectively. One-year and 10-year postoperative University of California Los Angeles (UCLA) shoulder scores and radiographs were compared. MRI was used to evaluate cuff integrity and fatty infiltration, and staging at 1 and 10 years was compared. Results: The 1-year and 10-year postoperative UCLA scores were 33.1 points and 32.9 points, respectively. There were no significant differences between the two groups. Plain radiography showed that osteoarthritis (OA) staging was significantly worse at 10 years postoperatively compared to 1 year postoperatively. Cuff integrity was maintained at an excellent level at 10 years postoperatively. Fatty infiltration significantly progressed up to 10 years postoperatively. Conclusions: At 10 years postoperatively, OA progression and fatty infiltration were observed; however, UCLA scores and cuff integrity remained well preserved.
