The traditional financial time series forecasting methods use accurate input data for prediction, and then make single-step or multi-step prediction based on the established regression model. So its prediction result is one or more specific values. But because of the complexity of financial markets, the traditional forecasting methods are less reliable. In this paper, we transform the financial time...
This paper verifies and discusses the structure of charismatic leadership style of management layer of fire protection unit, and develops a measuring tool that has a good reliability and validity to measure charismatic leadership style with each department office's staff of eight fire protection squadrons as research objects, based on the questionnaire of charismatic leadership style that was compiled...
The purpose of this research paper is to examine the relationship between self-concepts relating to two attributes necessary for successful engineers in today's society: creativity and global readiness. Some previous studies have shown a positive relationship exists between multicultural exposure and later creative performance. However, no studies were found that examine the relationship between students'...
Interactive online learning environment with audiovisual multimedia has improved significantly in increasing learning effectiveness. However, for hearing-impaired students who have difficulties in internet multimedia systems associated with audio and visual information require further design to overcome their limitation. To this end, the present study develops an interactive online learning environment...
Re-supplying loads on outage through cross-connect from adjacent feeders in a distribution system may cause voltage drop and hence require load shedding. However, the surplus PV generated in some of the LV feeders can prevent load shedding, and improve reliability. In order to measure these effects, this paper proposes the application of Direct Load Flow method[1] in reliability evaluation of distribution...
At present, the academic circles lack research of employee performance management for tourism planning companies, according to the concrete investigation of nine tourism planning companies in Beijing city, employee performance management as the research object, improving the management level as the target, combine with the basic theory and method of performance management, and on the specific situation...
We present the M.In.E.R.Va. project, an online tool to help students (both attending Secondary Schools and Universities) recovering their deficiencies in Mathematics. We also present an analysis of the answers given by the students, performed using the Rasch model, which allows to investigate both students' results and the validity of the items.
Micro-grid technologies have greatly attracted attention due to quick development of distribution energy resources. Micro-grid studied by researchers primarily includes AC micro-grid, DC micro-grid and AC-DC hybrid micro-grid. The advantages and application of these three types of micro-grids have been introduced and analyzed in this paper. The grid architecture, energy management, operation control...
The gaining popularity of Near Field Communication (NFC)-enabled applications has been facilitated by increased levels of NFC smartphone adoption. However, the existing touch-driven interaction using NFC smartphone for home environment is neither quick nor convenient. The primary contribution of this paper is to introduce a novel solution for a convenient mobiquitous home service, allowing users to...
Considering that the amount of money spent for implementing digital library is very high, it is therefore very crucial to evaluate its effectiveness. Since the implementation of digital library in the University of Tehran, Iran, no attempt has been made to evaluate its effectiveness. Against this concern, a study was carried out to investigate the effectiveness of the digital library from the user...
Associative Learning Skills are those skills that learners possess in order to associate previously learned concepts with new knowledge. Understanding learners' Associative Learning Skills can create opportunities to enhance learning experience by adapting the content and other aspects of instruction to individual learners. This paper analyzes three tools from the literature to determine their suitability...
This paper presents a novel method for calculating the unstable equilibrium point (UEP) for a two-bus system using holomorphic embedding (HE). The method is guaranteed to find the UEP solution. The focus of this paper is to prove mathematically that if a UEP solution exists, the method is guaranteed to arrive at that and only that solution and if no solution exists, then such is indicated by the oscillations...
The main purpose of this study is to reveal the influence factors of oil import to avoid the risk of oil import effectively. First, risk evaluation indices of oil import are screened and determined. Then the grey multi-level combination evaluation model is established. And it is used to evaluate the China's oil import risk. The evaluation results show that China's oil import risk is higher. The calculation...
In view of objective shortage of the present technology readiness assessment (TRA) method, TRA method based on close degree is proposed. Such key techniques is introduced with examples, such as the determination of number of layers in reference condition, build-up of reference condition, selection of characteristic parameter in reference condition and the processing mode of the characteristic parameter.
This study found a positive correlation between dual commitment and positive industrial relations climate while a negative correlation between dual commitment and negative industrial relations climate according to a questionnaire survey with 610 samples in several Wuhan's private enterprises. With a further research by using the Logistic regression model, the affective commitment, normative commitment...
With the development of the society, distance education and training gradually shows some characteristics similar to the service industry, such as invisible, cannot be stored, heterogeneous, serving and consuming in the same time and so on. To gain a bigger market share in competition and more reputation and brand value in development, distance education and training institutions must pay great attention...
Transformer is important power equipment in power system, of which the operation condition relates to the security and reliability of electric power system. The effective evaluation for transformer condition usually involves the information of multilayer, multivariable, and multi-target system, among which there are a lot of uncertainty factors, and only fully consider these uncertainty factors can...
A case analysis in this paper presents a business strategy evaluation framework based on three perspectives of a Taiwanese wireless networking solution provider, from the viewpoints of reliability in production, capability in solutions and flexibility in finance. This case study employs the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods with the fuzzy analytic hierarchy process...
In this paper, exponential utility functions have been adopted to deal with different types of indexes in order to reflect differences of various indexes value changes at different levels based on the characteristics of bid evaluation in construction projects. The value judgments of decision-makers have been considered to set up non-inferior relationship about all the bidders. The method of ELECTRE-II...
Support system of new equipment should be considered at preliminary development stage of equipment, so when baseline comparison system of new equipment is determined, it is necessary to give baseline comparison system of support system according to characteristics of new equipment, defects of replaced equipment and user's demands. This paper focuses on support resource in support system, defines support...
