IoT Based Smart Cradle Using PI

In this modern era, parents are busy building their lifestyle, carrier etc. As we know it has now become hard because parents have to take care of their children simultaneously, which paves a lot of work pressure and family pressure especially for women. Health of the child is affected and better care has also reduced. So, in order to handle such situation, we use temperature, Humidity, ultra-sonic Sensor. The conditions of the external atmosphere help to detect increased body temperature, babies voice while crying and their movements while they are continuously moving and also indicates the time for the diaper to be changed. If there are any abnormal activities are observed in baby’s atmosphere. An alert message is sent to the parents. In this system a video camera is attached and operated under the microcontroller’s instruction and it records a video when the motion sensor detects any continuous movements. The recorded video is broadcasted in a display to the parents which helps them to monitor baby in live. And in addition, this system detects and displays the status of the infant and alert the respective guardian by collecting values from sensor like temperature sensor, ultrasonic sensor, and also the location value from raspberry pi.

NEGOTIATING PROFESSIONAL BELONGINGS: FINNISH ACTORS’ AFFECTIVE ENGAGEMENTS ON SOCIAL MEDIA PLATFORMS

This study addresses how creative workers’ social media presence affects their understandings of professional agency. Focusing on Finnish professional actors, we ask how social media practices inform and shape actors’ occupational self-conceptions and professional belongings. In the theoretical framework, we employ Baym’s notion of relational labour and read it through Berlant’s (1998) conceptualisation of intimacy as mobile attachments. The data is collected from 15 Finnish actors, eight freelancers and seven theatre employees, from June 2020 to March 2021 by using the diary-interview method. The analysis is based on a close reading of the interview material and diary entries in which participants describe their experiences and feelings concerning their presence, work-related connections, and promotion on Facebook and Instagram. The study indicates that for both theatre actors and freelancers their social media activities are entwined in their sense of professionalism and belongings to occupational communities of peers. They negotiate and speculate about their social media presence in relation to peer assessments in a way that involves continuous movements between visibility and invisibility and between independence and interdependence. Our study suggests that to understand the ambivalences involved in creative workers’ presence on social media platforms, it is important to broaden the investigation from strategic self-promotion and audience engagement to questions of professional identities and communities.

Research on Discrete Semantics in Continuous Hand Joint Movement Based on Perception and Expression

Continuous movements of the hand contain discrete expressions of meaning, forming a variety of semantic gestures. For example, it is generally considered that the bending of the finger includes three semantic states of bending, half bending, and straightening. However, there is still no research on the number of semantic states that can be conveyed by each movement primitive of the hand, especially the interval of each semantic state and the representative movement angle. To clarify these issues, we conducted experiments of perception and expression. Experiments 1 and 2 focused on perceivable semantic levels and boundaries of different motion primitive units from the perspective of visual semantic perception. Experiment 3 verified and optimized the segmentation results obtained above and further determined the typical motion values of each semantic state. Furthermore, in Experiment 4, the empirical application of the above semantic state segmentation was illustrated by using Leap Motion as an example. We ended up with the discrete gesture semantic expression space both in the real world and Leap Motion Digital World, containing the clearly defined number of semantic states of each hand motion primitive unit and boundaries and typical motion angle values of each state. Construction of this quantitative semantic expression will play a role in guiding and advancing research in the fields of gesture coding, gesture recognition, and gesture design.

Movement Path Data Generation from Wi-Fi Fingerprints for Recurrent Neural Networks

The recurrent neural network (RNN) model, which is a deep-learning network that can memorize past information, is used in this paper to memorize continuous movements in indoor positioning to reduce positioning error. To use an RNN model in Wi-Fi-fingerprint based indoor positioning, data set must be sequential. However, Wi-Fi fingerprinting only saves the received signal strength indicator for a location, so it cannot be used as RNN data. For this reason, we propose a movement path data generation technique that generates data for an RNN model for sequential positioning from Wi-Fi fingerprint data. Movement path data can be generated by creating an adjacency list for Wi-Fi fingerprint location points. However, creating an adjacency matrix for all location points requires a large amount of computation. This problem is solved by dividing indoor environment by K-means clustering and creating a cluster transition matrix based on the center of each cluster.

The effects of expansion joint design on bridge life-cycle costs - initial investment versus total cost of ownership

<p>The need to maximise long-term value for money supports the consideration of life-cycle costs rather than just initial construction costs when investing in key infrastructure such as bridges. This is especially true in the case of a bridge’s expansion joints, which are much less robust than the structure as a whole yet subjected to continuous movements and dynamic loading. The life-cycle costs of a bridge’s expansion joints may be considered to include not only initial supply and installation costs, but also maintenance and repair costs throughout their service life, and replacement costs, and the user costs associated with maintenance and replacement work – especially those relating to traffic disruption. Increasingly, the effects of avoidable work on the environment should also be considered. This paper will address this topic, discussing issues that should be considered in choosing the optimal solution for any individual structure.</p>

Thromboprophylaxis Measures to Prevent Venous Thromboembolism in Hospitalized Patients

Venous thromboembolism (VTE) is a serious complication in hospitalized patients and is the most frequent cause of preventable death in these patients, in addition to being the third cause of death of cardiovascular origin. Even though the loss of recent or continued mobility represents an important predisposition related to the onset of VTE, there are no clear and uniform criteria for defining the concept of immobility. Despite this, it is currently known that the early mobilization and other non-pharmacological thromboprophylactic measures of the patient in the medical or surgical clinic is an essential measure for his full recovery and satisfactory prognosis. Therefore, it is always important to prescribe preventive multiprofessional care, such as lateral decubitus variation, bed positioning, passive continuous movements apparatus as use of a cycle ergometer (CE), compressive socks, intermittent pneumatic compression (IPC), electric stimulation, sitting position, orthostatism, transfer from bed to chair, walking, and insertion of a filtering device in the lower portion of the main human vein in order to guarantee recovery quickly, safely and free from the risk of developing fatal complications such as pulmonary thromboembolism (PTE). Our objective in this article is to briefly summarize the main non-pharmacological thromboprophylaxis measures that help prevent venous embolism, in addition to addressing other mechanical resources used to prevent complications of thromboembolic events described in the literature on this topic.

A laparoscopic study investigating 3D vs 2D imaging systems using a pelvitrainer model with experts, non-experts, and students

Background Vision is an essential element of laparoscopic surgery that defines the outcome of an operation in regards to time, mistakes and precision. A 3-dimensional (3D) perspective may improve vision during an operation. Therefore, this study was designed to compare 3D versus 2-dimensional (2D) perspectives using a pelvitrainer model. Methods Fifty candidates were divided into 3 categories based on different experience levels. The candidates were randomised into two groups, with each group performing the same 4 standardised tasks. Group A approached the tasks first with 3D high definition and in a second turn with 2D high definition. Group B carried out the tasks with the systems in reverse order. Task completion time and the number of mistakes made for each task were recorded. After completing the tasks, participants answered questions concerning the two systems. Results Group A was, on average, 20% faster at all four tasks and made approximately 18% fewer mistakes in two of the tasks in comparison to group B. The experts significantly benefited from the 3D system in terms of accuracy compared to non-experts and students. The students demonstrated a significantly greater benefit from the 3D system when performing non-linear, continuous movements. Loss of concentration occurred at the same rate for subjects using the 2D and 3D systems. Nausea and dizziness were reported only when working with the 3D system. 91% found the 3D system advantageous for accomplishing the tasks. Conclusions Irrespective of experience level, 3D laparoscopy shows advantages in saving time, increasing accuracy and reducing mistakes. These benefits were also accompanied by subjective advantages that were noted by the participants. However, the more complex the task, the less significant the benefit of the 3D system and some people feel handicapped by the eyewear.
