Application Of Naive Bayes Algorithm In Classification Of Child Nutrition At The Simalungun Health Office

Toddlers are among the most vulnerable groups to nutritional problems when viewed from the point of view of health and nutrition problems, while at this time they are experiencing a cycle of relatively rapid growth and development. .7% is quite high where the number of births is relatively large. Researchers try to classify 10 toddlers using WEKA to find out whether they have nutritional disorders or are normal by using 5 attributes as system input and a class namely nutrition which divides this class into 4 namely bad, less, good and more with the amount of training data 219 data then data compared with the actual nutritional conditions and obtained an accuracy of 60% and an error of 40% with these results it can be concluded that the accuracy is not too good. Based on this, it is hoped that the results of this classification can help further research in classifying the nutrition of children under five.

Nerve-mediated amputation-induced stem cell activation primes distant appendages for future regeneration events in axolotl

Animals exhibit extreme diversity in regenerative ability. This likely reflects different, lineage-specific selective pressures in their evolutionary histories, but how specific molecular features of regenerative programs help solve species-specific challenges has not been examined in detail. Here we discover that, in the highly-regenerative axolotl salamander, a conserved, body-wide stem cell activation response triggered in response to limb removal primes undisturbed limbs for regeneration upon subsequent amputation. This response should be particularly useful to salamanders, which frequently lose limbs in response to cannibalism. We further demonstrate the body-wide response requires both peripheral nervous system input at these distant sites and mTOR signaling. We defined gene expression changes within the nerves and nearby tissues, harboring responsive stem cells, leading to identification of candidate genetic pathways influencing distant stem cell activation following amputation. Functional experimentation confirmed a requirement for adrenergic signaling in amputation-induced activation of distant stem cells. These findings reveal a direct link between systemic cellular activation responses to local tissue damage and overall regenerative ability. Similar systemic activation responses to tissue removal have been observed in animals with widely differing regenerative abilities (e.g., planaria to mice), suggesting that it is the responses downstream of these signals, likely sculpted by differing evolutionary pressures, that ultimately distinguish regenerators from non-regenerators.

Design and research of hydraulic conversion system of wave energy generating device

Taking the hydraulic conversion system of the oscillating flapping-wing wave energy power generation device as the research object, a hydraulic conversion system is designed to convert wave energy into usable mechanical energy. Based on the principle of high-efficiency collection of wave energy and stable output of the hydraulic conversion system, the composition of the hydraulic conversion system and the parameters of each component are determined. According to different sea conditions, the pre-charge pressure of the accumulator is adjusted to keep the pressure of the high and low pipelines of the hydraulic system stable, and the mechanical energy is stably output through the hydraulic motor. The AMESim simulation platform is used to build the model of acquisition mechanism and hydraulic conversion system, simulate the motion response of acquisition mechanism under actual sea conditions as the system input, and analyze the effectiveness and output stability of hydraulic conversion system. The results verify that the designed hydraulic conversion system can achieve efficient collection of wave energy. The research results have laid a theoretical foundation for the development and research of wave energy power generation devices.

Rancang Bangun Sistem Informasi Rekam Medis (Studi Kasus: Klinik PKU Muhammadiyah Gandrungmangu)

Health Services at the PKU Muhammadiyah Gandrungmangu Clinic have not made much use of information technology. Documentation of patient medical records still uses a manual recording system, causing various obstacles; for example, officers often find the same medical record number and difficulties making reports. Thus, creating a medical record information system is necessary to help manage medical record data electronically. The system was developed using the prototyping method. This system has several features: medical record management, user management, reporting system, input checking feature for vital sign results, uploading feature for supporting examination results, and patient queuing system for each poly. The results of the user convenience test using the SEQ method obtained an average value of 6 and 7. The usability test results using the SUS method also got a good response from the questionnaire questions given to the respondents, which got a total score of 90.6, meaning that the system has an excellent usability level.

Design and Comparison of the Performance of 12-Pulse Rectifiers for Aerospace Applications

In this paper, a conventional 12-pulse transformer unit (CTU) and an autotransformer 12-pulse transformer unit (ATU) are compared in the view of the RTCA DO-160 standard for aircraft applications. The design of the magnetic components is proposed via a coupled FEM-circuital analysis in the time domain for an 800 Hz/2 kW system. Input AC distortion, power factor, and output DC ripple are evaluated through simulations. An accurate power loss analysis is carried out, taking into account copper losses, magnetic losses, and power losses due to power switches. The reduction in the size and weight of the ATU with respect to the CTU solution is discussed, including the need for filtering systems and the standard requirements.

Acoustic Word Embeddings for End-to-End Speech Synthesis

The most recent end-to-end speech synthesis systems use phonemes as acoustic input tokens and ignore the information about which word the phonemes come from. However, many words have their specific prosody type, which may significantly affect the naturalness. Prior works have employed pre-trained linguistic word embeddings as TTS system input. However, since linguistic information is not directly relevant to how words are pronounced, TTS quality improvement of these systems is mild. In this paper, we propose a novel and effective way of jointly training acoustic phone and word embeddings for end-to-end TTS systems. Experiments on the LJSpeech dataset show that the acoustic word embeddings dramatically decrease both the training and validation loss in phone-level prosody prediction. Subjective evaluations on naturalness demonstrate that the incorporation of acoustic word embeddings can significantly outperform both pure phone-based system and the TTS system with pre-trained linguistic word embedding.

Internet of things based attendance system design and development in a smart classroom

Attendance records are one of the main administrative roles on campuses. Therefore, several technologies can be used on an attendance system, including barcode, radio frequency identification (RFID), fingerprint, and faceprint. The main functions of attendance systems on campuses are mainly focused on how to obtain the attendee data list, store on the database, and display the list on the information system. This research proposes an attendance system in the smart classroom which supports the system’s previous activities as well as its integration with security and classroom management. In this system, the NodeMCU which was connected to the Wi-Fi router served as the controller, while the fingerspot revo FF-153BNC functioned as the system input. In addition, the database server was used to allocate attendee and classroom management data. This system is connected with the information system and classroom display unit, and component and system testing were applied in this research. The results showed that each system unit successfully integrated and managed the attendance, security, and classroom schedule.

Data collection techniques consist of secondary data obtained by studying literature studies in the form of writings or documents, primary data comes from the location of the study directly, besides that data collection through observation is also carried out, namely direct observation of how the system works, system problems, system input data, existing processes and system outputs

Specifying Power Filter Insertion Loss Values in Terms of Electromagnetic Safety of IT Equipment

At present, one of the main methods of minimizing risk resulting from electromagnetic information leakage is to attenuate the undesired levels of radiated and conducted disturbances generated by IT equipment, as these disturbances can carry information processed by said equipment. Attenuation of conducted compromising emissions is most commonly handled with filters with a sufficiently high insertion loss. This article defines an original analytical relation specifying insertion loss value requirements for mains filters and estimates values of parameters included in the defined relation. Furthermore, this defined relation was used to define requirements for insertion loss provided by the mains filters, above which the ratio value of potentially compromising conducted emission levels to the environmental noise level at the infiltrating system input S/N < 0 dB. As a consequence, electromagnetic infiltration is significantly impeded.
