Frequency shifting approach towards textual transcription of heartbeat sounds

Auscultation is an approach for diagnosing many cardiovascular problems. Automatic analysis of heartbeat sounds and extraction of its audio features can assist physicians towards diagnosing diseases. Textual transcription allows recording a continuous heart sound stream using a text format which can be stored in very small memory in comparison with other audio formats. In addition, a text-based data allows applying indexing and searching techniques to access to the critical events. Hence, the transcribed heartbeat sounds provides useful information to monitor the behavior of a patient for the long duration of time. This paper proposes a frequency shifting method in order to improve the performance of the transcription. The main objective of this study is to transfer the heartbeat sounds to the music domain. The proposed technique is tested with 100 samples which were recorded from different heart diseases categories. The observed results show that, the proposed shifting method significantly improves the performance of the transcription

Reliability assessment of microgrid with renewable generation and prioritized loads

With the increase in awareness about the climate change, there has been a tremendous shift towards utilizing renewable energy sources (RES). In this regard, smart grid technologies have been presented to facilitate higher penetration of RES. Microgrids are the key components of the smart grids. Microgrids allow integration of various distributed energy resources (DER) such as the distributed generation (DGs) and energy storage systems (ESSs) into the distribution system and hence remove or delay the need for distribution expansion. One of the crucial requirements for utilities is to ensure that the system reliability is maintained with the inclusion of microgrid topology. Therefore, this paper evaluates the reliability of a microgrid containing prioritized loads and distributed RES through a hybrid analytical-simulation method. The stochasticity of RES introduces complexity to the reliability evaluation. The method takes into account the variability of RES through Monte- Carlo state sampling simulation. The results indicate the reliability enhancement of the overall system in the presence of the microgrid topology. In particular, the highest priority load has the largest improvement in the reliability indices. Furthermore, sensitivity analysis is performed to understand the effects of the failure of microgrid islanding in the case of a fault in the upstream network

RANCANG BANGUN ATS UNTUK PEMBANGKIT CADANGAN (GENERATOR SET 1 PHASA)

Penelitian ini menggunakan jenis penelitian eskperimen dengan studi literatur, Penelitian ini bertujuan untuk mengetahui bagaimana proses pemasangan instalasi listrik dengan menggunakan generator set sebagai listrik cadangan serta mengetahui bagaimana pemanfaatan generator set sebagai alternatif ketika terjadi pemadaman listrik, untuk mempermudah pengoperasian generator set maka dibutuhkan system yang dapat bekerja secara otomatis dalam pengontrolannya, Penelitian ini menghasilkan alat Automatis transfer switch (ATS) yang dapat memindahkan suplai dari PLN ke Generator set ataupun sebaliknya. Metode yang digunakan dengan merancang alat yang dapat mendeteksi tegangan pada kedua sumber. Dari hasil pengujian didapatkan bahwa terdapat jeda waktu antara suplai PLN yang mengalami gangguan sampai genset dihidupkan dan siap dibebani yaitu sebesar 15 detik. Dan pada saat PLN kembali normal didapatkan jeda waktu kurang dari 5 detik dalam perpindahan suplai dari genset ke PLN

Pengaruh Pelatihan “Baturaja Risk Containment” Terhadap Kompetensi Dan Kinerja Karyawan PT.Semen Baturaja (Persero) Tbk. (Studi pada Karyawan Division Produksi)

This study aims to describe various analyzes on the implementation of training activities entitled "Baturaja Risk Containment" which includes aspects of training methods and training materials on changes in competence and changes in employee performance at PT Semen Baturaja (Persero) Tbk, especially in the operating division work unit. Partially this research will describe various analyzes among research variables, among others; describes the analysis of the effect of training methods on employee competencies; describes the analysis of the effect of training materials on employee competencies; describes the analysis of the effect of training methods on employee performance: training materials on employee performance, and describes the analysis of the influence of competence on employee performance. This research is an explanatory research carried out in the operations division. With primary data obtained from questionnaires distributed to employees totaling 58 people. This study applies data analysis methods in the form of descriptive statistical analysis methods and path analysis methods. The results of the analysis in this study show that there is a partially significant effect between 1) training methods and 2) training materials on employee competencies; Furthermore, the analysis in this study also shows that there is a partially significant effect: between 1) training methods, 2) training materials 3) competence on employee performance

Hubungan Karakteristik Personal Auditor Terhadap Perilaku Penyimpangan Dalam Audit

This study aimed to obtain empirical evidence about the relationship of personal characteristics of auditors, either individually (partial) and jointly (simultaneously) on the Dysfunctional Audit Behavior. Independent variables in this research that the personal characteristics of auditors that is formed by three indicators that shape it, among others, external locus of control, performance and turnover intention. While the dependent variable in this research that the behavior of irregularities in the audit. The data used in this study is the primary data obtained through questionnaires. Of the 80 questionnaires distributed, 63 questionnaires were returned and analyzed. Data analysis using regression methods. The results showed the first hypothesis (H1) is an external locus of control are positively related to behavioral aberrations in the audit is rejected, the second hypothesis (H2) is negatively related to performance of the behavior of irregularities in the audit is rejected, the third hypothesis (H3) turnover intention are positively related to behavioral aberrations in the audit is received
