Enhancing Non-intrusive Occupant Load Monitoring through Occupancy Matrix

It has been universally accepted that energy consumption in commercial buildings is highly related to occupant behaviors. Improving occupants’ energy-use behaviors is regarded as the most cost-effective approach to enhance overall energy saving in commercial built environments. However, effective behavior intervention pursuits rely on the availability of occupant-specific energy-use information, which is extremely expensive to capture with existing technologies. In this context, the author’s previous studies proposed the non-intrusive occupant load monitoring (NIOLM) approach that captures individual occupants’ energy-consuming information at their entry and departure events in an economically feasible manner. The NIOLM assigns energy-load variations (ev) of a building to individual occupants and relies on two variables: Time delay intervals and magnitudes of ev. This paper extends the existing NIOLM concept with the inclusion of a new variable, the occupancy matrix which manifests the information of present occupants at the moment of ev. An experiment has been conducted in an office space to validate the feasibility and accuracy of the proposed approach. Outcomes of this research could be a great help for studies on occupant energy-use behaviors intervention and simulation.

Implementation of Project Management System Based on Project Management

With the rapid development of information technology and the gradual expansion of education, the construction of campus information is accelerating. The use of information technology to promote teaching reform is an important idea for the current school education reform, it is to improve the quality of teaching specifi c measures, especially new requirements is needed for colleges and universities as they continue to expand enrollment and teaching resources. Way to make full use of limited resources, use more scientifi c management methods and teaching methods, improve work effi ciency, ensure the quality of teaching, improve the eff ectiveness of running a school, has become an important subject of university research. The application of computer in teaching management is the key to realize the scientifi c and modern teaching management. To improve the quality of teaching, we must grasp the various teaching links. The examination is an important part for the students to test the eff ect of learning. Objective evaluation of the students as a means of curriculum construction is also an important part. In the school teaching work, the traditional test questions management is usually in the form of questions or test paper set, and design manually by teachers, which is large, and complex. The automatically generation system for test paper integrated the traditional manual volume, which solves a lot of problems, such as avoid unnecessary duplication of eff ort, saving the human resources and time; the use of scientifi c measures to evaluate and evaluate the diffi culty of harmonizing papers, the eff ective quality of test papers; and a signifi cant reduction in the probability of missing errors in the test paper, reduce unnecessary trouble

Realization of Spectrum Analysis of Speech Signal Based

MATLAB is a very powerful engineering and practical software for data analysis and processing. It is very convenient to analyze and deal with it. This paper introduces how to collect the speech signal and voice signal acquisition in MATLAB environment, and analyze the MATLAB of speech signal processing by an example. The basic principle and basic process of texture image analysis based on Fourier transform spectrum are described by MATLAB simulation of sinusoidal texture image and spectral characteristic analysis of sinusoidal texture image. The program is written, and the spatial texture image with ideal sine distribution is obtained, and its spectral characteristics are analyzed. According to the defi nition of discrete Fourier transform DFT, a method of calculating the amplitude spectrum of discrete signal by DFT is deduced. The eff ectiveness of the method is verifi ed by MATLAB simulation.
