Published: February 2020

Entre 1885 y 1930, luego de las campañas militares contra los pueblos indígenas, el norte de la actual provincia de La Pampa comenzó a ser ocupado por instalaciones relacionadas con la explotación rural: estancias con sistema arrendatario, colonias, poblados y asentamientos comerciales. Desde 2008 nos encontramos estudiando esta problemática que se enmarca dentro de la denominada arqueología rural. En este trabajo se presentarán los avances preliminares con respecto al abordaje del sitio “Casa de Negocios La Estrella” (1884-1946) ubicado en las proximidades de la ciudad de Parera (Departamento de Rancul, provincia de La Pampa). Dicho sitio se trata de una pulpería o boliche que se hallaba en una intersección de caminos que lo vinculaba con diversos tipos de asentamientos (estancias, puestos y otros almacenes y casas de negocios) conformando parte constitutivo del paisaje rural reciente. En la campaña 2018 se realizó la determinación de la extensión del sitio, se recolectaron sistemáticamente los materiales de superficie y se realizaron 14 sondeos. Se comenzará con el análisis de mapas históricos a través del GIS, luego se explicitará la metodología de campo utilizada y finalmente se describirán los procesos de formación de sitio que afectaron a los materiales recuperados en los sondeos.

Self-Care Confidence and eHealth Education in Adults with Asthma: Do They Reduce Healthcare Utilization?
Authors: Arnoldussen Barbara
Published: February 2020

Abstract
Introduction: The purpose of this research was to analyze personal characteristics and behaviors associated with adults with asthma. Does self-care confidence or eHealth education reduce their healthcare utilization to decrease medical costs? Methods: Using 2015 California Health Interview Survey (CHIS) data, the study examined the data of adults (n = 3380) with asthma. Chi-square tests calculated differences for eight personal characteristics and behaviors: gender, age, education, online health information searching, self-reported health status, physical activity limitations, emergency room visits, and hospitalization related to asthma. Individuals very confident to manage their asthma were compared to those feeling less empowered to manage their health. Individuals who recently used the Internet to find health information were compared to those who did not go online for resources. Results: CHIS data showed a lack of full self-care confidence in a quarter of surveyed asthmatics. Better self-reported health status correlated with increased self-care confidence. Women, those with less education, and those with physical activity limitations were less confident to manage their health. Fewer people who were fully self-confident visited emergency rooms for asthma. Self-confidence had no effect on the rate of hospitalization. The use of eHealth education was significantly more frequent in people under 70 years old, those with less than a high school education, and those without physical activity limitations. Better self-reported health status correlated with increased eHealth education use. More people who used eHealth education visited emergency rooms for asthma. eHealth education had no effect on the rate of hospitalization. Conclusions: It is possible to identify individuals with asthma with an increased risk of not feeling confident about their ability to manage their disease. Health care professionals can plan extra in-person efforts to educate asthmatics who feel insecure about managing their health. Women, individuals in poor or fair health, and those with physical activity limitations should be assessed for self-care confidence soon after diagnosis and monitored at regular intervals. Full self-care confidence correlated with fewer visits to ERs. eHealth education was not shown to play a role in reduced healthcare utilization.

The Lung Cancer is a most common cancer which causes of death to people. Early detection of this cancer will increase the survival rate. Usually, cancer detection is done manually by radiologists that had resulted in high rate of False Positive (FP) and False Negative (FN) test results. Currently Computed Tomography (CT) scan is used to scan the lung, which is much efficient than X-ray. In this proposed system a Computer Aided Detection (CADe) system for detecting lung cancer is used. This proposed system uses various image processing techniques to detect the lung cancer and also to classify the stages of lung cancer. Thus the rates of human errors are reduced in this system. As the result, the rate of obtaining False positive and (FP) False Negative (FN) has reduced. In this system, MATLAB have been used to process the image. Region growing algorithm is used to segment the ROI (Region of Interest). The SVM (Support Vector Machine) classifier is used to detect lung cancer and to identify the stages of lung cancer for the segmented ROI region. This proposed system produced 98.5 % accuracy when compared to other existing system.

Amongst major industries, the aircraft industry has gained momentum not only in public transportation, but also in defence, business and space sectors. The electrical, mechanical and electronic systems of an aircraft are all interconnected by different types of cables like hook up wires, cables for high speed data transmission, cables for power transmission, fire resistant cables, co-axial cables etc , with each type of cable having its own specifications. Military Standard 1553 (Mil-Std 1553) is one such cable primarily used for on-board aircraft sub-system communication and monitoring. Mil-Std 1553 protocol defines the physical and electrical properties of the cable. Mil-Std 1553 is a dual redundant bus, that is, there are two channels for a single bus communication. Mil-Std 1553 is prone to faults like opens or shorts because of its continuous wear and tear in aircraft environment. If a faulty cable is operated, then it possesses a high risk to the aircraft system .As of now ,there is no automatic fault detection system employed on Mil-Std 1553. Hence there is a need for automatic fault detection system on Mil-Std 1553 cables before the entire system collapses. In this regard, modeling of Mil-Std 1553 is very important since the developed model can be used for testing of the fault detection algorithm and further prototype development. Here, the Mil-Std 1553 cable has been modeled using SIMULINK/MATLAB. The cable is modeled under two different scenarios: considering only the Test Signal , considering both Test Signal and Data Signal. The cable is modeled considering all its electrical characteristics for three conditions, namely, No Fault condition, Open circuit condition and Short circuit condition. PI section is used as an elemental block for modeling of Mil-Std 1553.

Devices associated with Internet of Things are typically constrained in their resources and do not have the computational power necessary to analyze their input and detect anomalies that occur. Smart devices or and environmental sensors that measure temperature, air quality, or seismic activity are all built for specific purposes with minimal resources and often do not have enough security in place to protect against infiltration or detect abnormal behavior. Additionally, because these devices and sensors are typically always connected and transmit constant data in near real-time, the high dimensionality of the raw readings are extremely computationally intensive to analyze. A possible solution to reduce the dimensionality of the data while also extracting the most significant features is to use multivariate analysis techniques such as Principal Component Analysis. PCA is a method of multivariate analysis meant to reduce the size of matrices while not only keeping the most significant variables but also learning the interactions between them. In this paper, we propose exploring anomaly detection in IoT using multivariate analysis techniques to reduce the dimensionality of sensor input to reduce the computational complexity of analysis and learning the most significant variables. While the normal conditions of sensor data are often readily available, the size of the data makes it difficult to precisely determine instances of targeted anomalies. In this study, PCA is used to analyze the available features of the data and from them can determine the sensors under normal conditions. Once the normal conditions are determined, outliers which constitute anomalies can be determined through techniques such as Mahalanobis distance to determine the variance of each observation from the normal distribution. Our work can also be expanded to use other methods of dimensionality reduction and feature extraction such as t-Distributed Stochastic Neighbor Embedding.

Pulse Compression (PC) technique has many advantages in signal processing of radar systems which enhances the radar performance. For a long pulse, the range detection capability can be increased with PC while maintain the advantage of resolution in range for uncompressed pulse. There are many PC techniques such as Binary and Linear Frequency Modulation (LFM) Codes, which can be utilize in radar. The radar detection performance is affected by unwanted signals, which called side lobes that may mask the weaker useful signals, which are present near to strong signals. Pulse compression that uses LFM code is discussed and contrasted with matched filter keep tracked of Hamming windowing filter technique to eliminate the level effect of side lobes. In the present paper, a proposed optimum filter is introduced to enhance both the radar detection capability and resolution in range. The proposed optimum filter representation is evaluated and compared with the classical matched filter response associated with Hamming windowing filter according to the representation of radar detection through Receiver Operating Characteristics (ROC) curves and resolution performance.

A Mobile Ad-hoc Network (MANET) is a lot of nodes that impart together agreeably utilizing the remote medium, and with no focal organization. Because of its inborn open nature and the absence of framework, security is a convoluted issue contrasted with different systems. That is, these systems are powerless against a wide scope of attacks at various system layers. At the system level, malignant nodes can play out a few attacks going from detached spying to dynamic meddling. Blackhole is a case of serious attack that has pulled in much consideration as of late. It includes the traffic redirection between end-nodes via Blackhole attack, and also controls the directing calculation to give figment to the nodes situated a long way from one another are neighbours. To handle this issue, we are proposing a novel location model to enable a node to check whether an assumed most limited way contains a Blackhole attack or not. Our methodology depends on the way that the Blackhole attack diminishes essentially the length of the ways going through it.

Stock market is highly volatile and it is necessary for investors to have an accurate prediction of stock prices for a better profitability. Towards this need many methods have been proposed for stock market prediction with aim to provide a higher prediction accuracy. Current methods for stock market prediction are in two categories of machine learning and statistics based. Considering the need for accurate prediction in short term and long term, the merits of both methods must be combined for accurate prediction. This work proposes a hybrid deep learning approach for stock market prediction which combines the historic price-based trend forecasting along with stock market sentiments expressed in twitter to predict the stock price trend.

The article deals with the problem of remote search for hidden transmitters in a large office. Such a search should be performed inconspicuously for office visitors so that an attacker could not turn off the transmitter during the search. The complexity of the inconspicuous manual search for bugs is shown and the necessity of using a remote automated search for illegal transmitters is substantiated. The decision on the use of remote search can be made on the basis of a priori knowledge of the localization precision of a hidden transmitter. To calculate the precision of localization, a mathematical model is proposed on the basis of measuring the distances from the receiving antennas to the alleged hidden transmitter. The range and the precision of the distance from the transmitter to the receiving antenna can be calculated by knowing the attenuation of the signal during its propagation under certain conditions. The more heterogeneous the wave propagation environment, the greater the error in determining the range. The localization precision of the hidden transmitter is calculated using the Least Squares Method. The main parameter of localization precision is the Mean Square Error of its location. It is shown that the values of the Mean Square Error of localization depend both on the precision of the range measurement and on the position of the receiving antennas relative to the transmitter. The capabilities of the developed model for determining the required number of receiving antennas at a given localization precision are also shown. The simulation of a multi-storey office building was carried out and the parameters of localization precision were estimated for a different number of receiving antennas. The possibility of increasing the precision of localization with an increase in the number of antennas has been confirmed. The article concludes that it is advisable to use such a model when building scanners to search for illegal bugs and transmitters.

there are several topics and areas that are at an advanced stage of interest and research around the world because of their importance and usefulness to humanity, including the sentiment analysis. By studding of sentiment analysis (SA), one can learn about the mysterious things and different feelings of others. The purpose of all of this is to know the pros and cons about a product or anything else and correct the negatives in future that are found. In our research, we have benefited from social media sites, especially Twitter, in collecting data about the iPhone 11 product to see how satisfied customers are about this product. We collected a lot of different opinions using API and then transferred them to an information bank. In our research we used the famous Naive Bayes (NB) algorithm and had an active role in classifying reviews and sorting them and knowing the pros and cons, where we got good results compared to previous works which are as follows: precision 80, recall 83, f1 score 81, accuracy 80.25.

Friction Stir Welding (FSW) is a topical and propitious solid-state joining process producing economical and strengthened joints of age-hardened and heat-treatable Aluminium Alloy AA 6082-T6. Mechanical and fractural behaviour of weldments were investigated in order to find crack initiation and necking on the weld zone thereby perceiving the complete behaviour of fracture occurred near the weld zone. Weldments are fabricated by employing four tool pin profiles namely MX-TRIVEX, A-SKEW, Three flat threaded and Concave shouldered MX-TRIFLUTE tools at various rotational speeds 1000 rpm, 1200 rpm and 1400 rpm at single traverse speed 25 mm/min. EXCETEX-EX-40 CNC wire cut EDM with 0.25 mm brass wire diameter has been employed to perform the extraction of tensile test specimens from the weldments according to ASTM E8M-04 standard. Tensile test was performed on elctro-mechanically servo controlled TUE-C-200 (UTM machine) according to ASTM B557-16 standards Maximum Ultimate Tensile Strength (UTS) of 172.33 MPa (55.5% of base material) and 0.2% Yield Stress (YS) of 134.10 MPa (51.5% of base material) were obtained by using A-SKEW at 1400 rpm, 25 mm/min and maximum % Elongation (%El) of 11.33 (113.3% of base material) was obtained at MX-TRIVEX at 1000 rpm, 25 mm/min. Minimum UTS of 131.16 MPa (42.30% of base material) and 0.2% YS of 105.207 MPa (40.46% of base material )were obtained by using Concave shouldered MX-TRIFLUTE at 1400 rpm, 25 mm/min. Minimum % El of 5.42 ( 54.2% of base material) was obtained by using A-SKEW at 1000 rpm, 25 mm/min.
