Exploring Cardiac Disease Based on ML in IOT: A Comprehensive Study

Every human being in today’s age has high importance in a stable human life. With daily new technology is launched in a world loaded with innovative business sectors to tackle more effectively the prevalent challenges of the world. We ought to figure out if as many people as possible can be spared. The death rate of multiple non-communicable heart disease forms is rising steadily each year. Many non-communicable disorders are long-term, gradual and too serious that a patient’s situation is too critical to control. This leads to a sudden heart attack for most people or learning about their condition before it is too late. In this document we suggest a cardiovascular state prediction approach for IoT and Machine Learning, which will use IoT system (sensors) to capture the data needed from the human body and move it to the cloud where data is saved with user verification. The obtained information from the human body is then normalized to quantify and forecast the total condition before AI calculations are applied to them.

Health Status Comparison of Blood Cockle (Tegillarca granosa) between Low and High Yield Farms in Selangor and Johor

This study aims to provide insight knowledge on the potential reason for low blood cockles (Tegillarca granosa) production in Sungai Buloh Selangor by comparing the condition indices and histology of the gills and gonad with samples from a high yield farm at Sungai Ayam, Johor. Samples were collected in September 2020 and grouped for histological analysis and for condition indices. About 60% individuals from Sungai Buloh and 20% of samples from Sungai Ayam found with degenerated gill filaments. The sex ratio were found identical (50%:50% male to a female) in samples from Sungai Ayam, while 40%: 60% of male to female from Sungai Buloh. The gonad of males found at Stage 2 (developing) and Stage 3 (developed or ripe) and the ovaries at Stage 3 and Stage 4 (spawning) for Sungai Buloh, and between Stage 2 to Stage 4 from Sungai Ayam. The total condition index (CI Tot) was significantly differences between farms. Findings indicate sample from Sungai Buloh has low health status due to poor gill’s filaments condition, and ripe ovaries found in lightweight (2 g) T. granosa. Hence being the potential reason for low survival rate in the Sungai Buloh.

Positive impact of COVID-19 outbreak on the treatment of contamination fear in obsessive-compulsive patients in Armenia

Objective: To observe the effects that the COVID-19 pandemic has had on patients with contamination fear at obsessive-compulsive disorder (OCD), and how this can be used to improve psychotherapeutic treatment. Materials and methods: 33 patients were involved, divided into 2 groups, in one of which we used additional experimental features of psychotherapy. OCD total condition and separate symptoms were assessed using Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Results: Patients, included in Group A, showed significantly better improvement in both total Y-BOCS score, as well as in particular symptoms connected with so-called mental contamination. Conclusions: Adding reality-based and emotionally significant features of contamination control and prevention to standard cognitive-behavioral therapy protocol may seriously improve outcomes in the treatment of mental contamination obsessions. The period of pandemics, as well as post-pandemic, can be used for intense further research in this area in a larger selection of patients. Long-term follow-up is recommended to clarify the stability of positive changes.

A New Method for Impeller Inlet Design of Supercritical CO2 Centrifugal Compressors in Brayton Cycles

Supercritical Carbon Dioxide (SCO2) is considered as a potential working fluid in next generation power and energy systems. The SCO2 Brayton cycle is advantaged with higher cycle efficiency, smaller compression work, and more compact layout, as compared with traditional cycles. When the inlet total condition of the compressor approaches the critical point of the working fluid, the cycle efficiency is further enhanced. However, the flow acceleration near the impeller inducer causes the fluid to enter two-phase region, which may lead to additional aerodynamic losses and flow instability. In this study, a new impeller inlet design method is proposed to achieve a better balance among the cycle efficiency, compressor compactness, and inducer condensation. This approach couples a concept of the maximum swallowing capacity of real gas and a new principle for condensation design. Firstly, the mass flow function of real gas centrifugal compressors is analytically expressed by non-dimensional parameters. An optimal inlet flow angle is derived to achieve the maximum swallowing capacity under a certain inlet relative Mach number, which leads to the minimum energy loss and a more compact geometry for the compressor. Secondly, a new condensation design principle is developed by proposing a novel concept of the two-zone inlet total condition for SCO2 compressors. In this new principle, the acceptable acceleration margin (AAM) is derived as a criterion to limit the impeller inlet condensation. The present inlet design method is validated in the design and simulation of a low-flow-coefficient compressor stage based on the real gas model. The mechanisms of flow accelerations in the impeller inducer, which form low-pressure regions and further produce condensation, are analyzed and clarified under different operating conditions. It is found that the proposed method is efficient to limit the condensation in the impeller inducer, keep the compactness of the compressor, and maintain a high cycle efficiency.

The Lightweight Autonomous Vehicle Self-Diagnosis (LAVS) Using Machine Learning Based on Sensors and Multi-Protocol IoT Gateway

This paper proposes the lightweight autonomous vehicle self-diagnosis (LAVS) using machine learning based on sensors and the internet of things (IoT) gateway. It collects sensor data from in-vehicle sensors and changes the sensor data to sensor messages as it passes through protocol buses. The changed messages are divided into header information, sensor messages, and payloads and they are stored in an address table, a message queue, and a data collection table separately. In sequence, the sensor messages are converted to the message type of the other protocol and the payloads are transferred to an in-vehicle diagnosis module (In-VDM). The LAVS informs the diagnosis result of Cloud or road side unit(RSU) by the internet of vehicles (IoV) and of drivers by Bluetooth. To design the LAVS, the following two modules are needed. First, a multi-protocol integrated gateway module (MIGM) converts sensor messages for communication between two different protocols, transfers the extracted payloads to the In-VDM, and performs IoV to transfer the diagnosis result and payloads to the Cloud through wireless access in vehicular environment(WAVE). Second, the In-VDM uses random forest to diagnose parts of the vehicle, and delivers the results of the random forest as an input to the neural network to diagnose the total condition of the vehicle. Since the In-VDM uses them for self-diagnosis, it can diagnose a vehicle with efficiency. In addition, because the LAVS converts payloads to a WAVE message and uses IoV to transfer the WAVE messages to RSU or the Cloud, it prevents accidents in advance by informing the vehicle condition of drivers rapidly.

The Job Satisfaction of Ukrainian Police Officers: Condition, Structure and Key Predictors

Purpose. To determine the condition, structure and key predictors of job satisfaction of Ukrainian police officers. The study involved police officers of the National Police of Ukraine (age – 19-50 years, n = 203 – men, n = 52 – women). The questionnaire was applied. The results of the questionnaire were processed by mathematical statistics methods. coworkers, supervision and the nature of work. The most significant correlation is revealed between the gender and the level of satisfaction with fringe benefits, pay, operating conditions. Ukrainian subordinate police staff members less satisfied with the job than their line managers (average means are 108.2 and 117.6 respectively). The correlation matrix indicates that there are no multicollinear factors: all aspects of job satisfaction of police officers do not have a high correlation with each other (r<0.7). The multiple regression analysis confirms that the level of satisfaction with some aspects of the job (promotion, supervision, coworkers and communication) explains 82.6% of the sample. Such data can be considered the most influential predictors. The revealed condition and structure of satisfaction of Ukrainian police officers testify to its risk level and the necessity of its constant monitoring. The level of the police officers physical fitness confirmed a weak correlation with the total condition of job satisfaction. It is required a separate study devoted to the police officers, whose activities are associated with the significant physical load.

EFFECT OF PERMEABLE VESSEL CLOSURE AND GELLING AGENT ON REDUCTION OF HYPERHYDRICITY IN IN VITRO CULTURE OF CARNATION

Hyperhydricity, an abnormal morphological appearance and physiological<br />function, is an important problem in carnation tissue culture. The problem causes premature flowering, high occurrence of abnormal shoots, difficulty in transferring hyperhydric plantlets to soil, and low survival rate of plantlets. High relative humidity and the water potential are considered as the key factors involved in the abnormality. Furthermore, permeable culture vessel and gelling agent were assured to be high potential treatment to eliminate it. Objective of this research was to reduce hyperhydricity in regenerants of carnation using different permeable vessel closures and gelling agents and to assess the multiplication and acclimatization abilities of recovered shoots. Experiment was arranged in randomized complete block design with four replications. First factor was different types of closure, i.e. cotton wool, plastic wrap, parafilm and aluminium foil, while second one was gelling agents, i.e. bacto agar, phytagel, swallow agar, and Type 900 agar. The recovered shoots were then multiplied, rooted, and acclimatized. The results showed that hyperhydricity was successfully reduced by applying permeable closure (cotton wool and plastic wrap) in combination with Type 900 agar. The combination of plastic wrap and Type 900 agar was the most appropriate treatment in reducing hyperhydricity and producing good quality shoots. The treatment reduced the problem down to 23% of total condition of hyperhydricity (100%) and increased leaf chlorophyll content from 0.0883 to 0.1288 mg mg-1. The plastic wrap was easily applied and cheaper material compared to cotton wool. The recovered shoots were able to produce 1-3 healthy axillary shoots and easily rooted on half-strength MS. The recovered plantlets were simply acclimatized with survival rate up to 100% on kossas peat + soil (1:1, v/v) and flowered 4-5 months after acclimatization with decreasing in number and size of flower.

The Universality of Technology and the Independence of Things

In the 1949 Bremen Lectures, Martin Heidegger characterizes the essence of technology as a universal, or total, condition of modern existence. This makes it appear as though nothing can exist in the world independent of the technological. The fact that technology attempts to do away with distance, however, means that technology’s very workings presuppose the existence of distance and nearness that oppose it. Things, insofar as they are, according to Heidegger, essentially near remain independent of technology. By describing the nearness and nearing of things, this article reinterprets the Heideggerian concepts of the fourfold and world-formation to critically challenge the universality of technology. The human experience of things in their spatiality—especially the human aesthetic enjoyment of and abiding with things—is an example of a facet of life where technology does not annihilate distance and nearness.
