Toward Piano Teaching Evaluation Based on Neural Network

With the rise of piano teaching in recent years, many people participated in the team of learning steel playing. However, expensive piano teaching fees and its unique one-to-one teaching model have caused piano education resources to be very short, so learning piano performance has become a very extravagant event. The factors affecting music performance are varying, and there are many types of their evaluation such as rhythm, expressiveness, music, and style grasp. The computer is used to simulate this evaluation process to essentially identify the mathematical relationship between factors affecting music performance and evaluation indicators. The use of computer multimedia software for piano teaching has become a feasible way to alleviate the contradiction. This paper discusses the implementation method of piano teaching software, the issues of computer piano teaching, the computer teaching as one-way knowledge, and the lack of interaction. The neural network (NN) model is used to evaluate the piano performance and simulate teachers to guide students through their exercise. The performance of the proposed system is tested for the piano music of “Ode to Joy,” which is different from the collection of NN training samples, and is delivered ten times by another piano teacher, student A (piano level 6), and student B (piano level 5).

The Contribution of Staff Discipline and Promotion on the Development of Giwa Local Government Area

The study assessed the Effects of Discipline on Staff Performance in Local Government. The study was conducted in Giwa Local Government Area, Kaduna State. The study is a qualitative research method. Four research objectives were stated with four correspondent research questions and three assumptions. The instrument used for collecting data for the study was focus group discussion. Data were collected from respondents drawn from Giwa Local Government Area. Data collected were analyzed qualitatively. The study revealed that lack of discipline in the Local Government is sine qua non to the failures in the achievement of the desire, designed goals and objectives of Local Government and as such noted that Giwa Local Government should see discipline as an integral part of staff performance. The first finding showed that, Kaduna State Government through the adaptation of APER (Annual Performance and Evaluation Reports) has conditioned and discipline the staff as those discipline are partially promoted. The study also revealed that discipline has contributed to the development of Giwa Local Government as such recommends that certain incentives should be provided to energize the commitment of the disciplined staff so as to satisfactorily perform their assigned jobs in the Local Government Area.

PET Imaging in Cardiac Sarcoidosis: A Narrative Review with Focus on Novel PET Tracers

Sarcoidosis is a multi-system inflammatory disease characterized by the development of inflammation and noncaseating granulomas that can involve nearly every organ system, with a predilection for the pulmonary system. Cardiac involvement of sarcoidosis (CS) occurs in up to 70% of cases, and accounts for a significant share of sarcoid-related mortality. The clinical presentation of CS can range from absence of symptoms to conduction abnormalities, heart failure, arrhythmias, valvular disease, and sudden cardiac death. Given the significant morbidity and mortality associated with CS, timely diagnosis is important. Traditional imaging modalities and histologic evaluation by endomyocardial biopsy often provide a low diagnostic yield. Cardiac positron emission tomography (PET) has emerged as a leading advanced imaging modality for the diagnosis and management of CS. This review article will summarize several aspects of the current use of PET in CS, including indications for use, patient preparation, image acquisition and interpretation, diagnostic and prognostic performance, and evaluation of treatment response. Additionally, this review will discuss novel PET radiotracers currently under study or of potential interest in CS.

Study of Various Configurations of Hybrid PV/T System

In this study, an attempt has been made to evaluate the theoretical performance and evaluation of a hybrid PV/thermal (PV/T) collector based on dual heat extraction operation a function of climatic and design parameters. On the first hand, the different configurations of hybrid collectors are considered for the present study which are defined as unglazed PV/T air heaters, with and without tedlar, PVT hybrid water collector, in the second hand two configurations with dual extraction operation (water and air as heat removal fluid) are presented which are defined as dual PV/T model with tedlar, dual hybrid PV/T without tedlar. Analytical expressions for the temperatures of solar cells, back surface of the module, outlet air, and outlet water of those configurations have been derived. Numerical computations have been carried out for composite climate and the results for different configurations have been compared. Our results clearly show the direct impact of various parameters, in particular the solar radiation, ambient temperature, mass flow rate on the variation of outlet and solar cell of the collector.

A Study and Assessment of the Carbon Footprint of Tianjin University’s Weijin Road and Peiyangyuan Campuses, China

BackgroundA living University campus is like a model city; its energy and carbon auditing can also model how energy and carbon can be studied and analyzed in a city. China’s colleges and universities face grave problems, now and in the future - from declining quality of campus environments to deteriorating building performance, antiquated facilities, and inefficient energy and resources consumption. While research and discussion exists on improving existing university buildings’ energy performance and evaluation standards - much of that research focuses on energy savings, rather than on greenhouse gas emissions reductions. Calculation of campus carbon emissions is the first step for transforming and planning each existing university to carbon neutral campus. Some researchers of campus carbon emissions in China have made calculations, which, although as yet unpublished, create an initial framework for carbon-neutral campus plan targets. The present research gives an overview of universities’ drive towards sustainability in China and in other countries. The paper then details carbon footprint accounting steps, quantifying major carbon emission sources and carbon sequestration by vegetation inside the Tianjin University’s Weijin Road and Peiyangyuan Campuses. Results from China’s universities are compared with international results in the scientific literature. In this paper, based on this data, we suggest strategies and show preliminary target settings for how to transform Weijin Road into a carbon-neutral campus. ResultsAnnual carbon emissions for 2019 of the Weijin Road campus were 58,172.68 tonnes, (2.60 tonnes per person), and Peiyangyuan campus, 55,213.75 tonnes (2.46 tonnes per person). The largest sources of the two campuses’ greenhouse gas emissions were electricity and gas; Weijin Road campus; electricity = 61.42%, gas = 20.73%, and Peiyangyuan campus electricity = 69.32%, gas = 11.60%. Carbon sequestered in the two campuses by vegetation are 11,257.34 tonnes and 27,856.51 tonnes respectively. The renewable energy contribution to carbon reduction in Peiyangyuan campus is 50.85 tonnes.ConclusionPer person carbon emissions of Tianjin University’s two campuses are below the average for some US campuses, but are also greater than some in European countries. Research may investigate methods used by successful campuses towards becoming carbon neutral.

Construction of Evaluation Model of Surface Soil Erodibility Factors in Black Soil Area

The increasing soil erosion in black soil area has caused widespread concern from all walks of life. Based on this background, the evaluation model of surface soil erodibility factor in black soil area is studied and constructed. The data of erosion gully is from the general survey data of surface soil erosion gully in black soil area. After quantifying the morphological characteristics of the data, the vector data of erosion gully are gridded by fractal theory. The number of non-empty grids is calculated by the attribute query function of ArcGIS, and the pixel size is transformed in turn to obtain different coverage grids and corresponding fractal parameters. The surface soil runoff and soil erosion process in black soil area are simulated by PESERA model. To build the surface soil erosion model of black soil area, in the process of building the user-defined model, it needs to carefully select the parameters used for modeling, and it needs to consider all the factors that may play a role in the whole process of soil erosion. The factors of surface soil erodibility in black soil area are analyzed, including spatial distribution characteristics of soil erodibility’s K value, semivariance function analysis of soil erodibility’s K value, and spatial distribution characteristics analysis of soil erodibility’s K value. Finally, the evaluation model of surface soil erodibility factor in black soil area is constructed. By testing the quantitative performance and evaluation accuracy of erodibility factors, it is proved that this method has good quantitative performance and evaluation accuracy of erodibility factors, and has strong practicability.

NETWORK GOVERNANCE OF TOURISM SECTOR DURING IN COVID-19 PANDEMIC: CASE BINTAN REGENCY, INDONESIA

The development of tourism in Indonesia during the COVID-19 pandemic experienced a decline in tourism activities. This is due to the dominance of tourism depending on foreign tourists. Bintan Regency has a strategic area with the border of neighboring countries, strengthening Network Governance both formally and informally. This paper aims to analyze the current conditions involving stakeholders in the network governance dimension. The research method is a qualitative case study in Bintan Regency, primary data from informants through interviews including stakeholders and observations obtained by researchers then using triangulation techniques. Further analysis of the research discussion using a logical model is then analyzed in depth. The results showed that Network Governance in the tourism sector during the COVID-19 pandemic, including the management and leadership dimensions, did not involve all stakeholders. Furthermore, the Knowledge and Information Exchange dimension shows that the government still relies on social media as a platform. Then the dimensions of power and inter-organizational decision-making are dominated by the central government, which acts as a policymaker. However, the dimensions of legitimacy in recognition from the central government to develop priority destinations and the accountability of local and central governments are still constrained by the COVID-19 pandemic in the tourism sector, so that international tourism cooperation has not been able to implement. And finally, on the dimensions of performance and evaluation, the application of interpretation focuses on the principle of collaboration in the tourism sector during the COVID-19 pandemic and evaluation on strengthening regulations for non-formal forums such as Sustainable Tourism Development because the law can strengthen network governance in the tourism sector in Bintan Regency in COVID-19 pandemic.
