INVESTIGATION ON RELIABILITY AND MAINTAINABILITY OF AIR-CONDITIONING EQUIPMENT

an investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...

Study of an Individual Air-Conditioning Energy-Saving Equipment

Vision Based Navigation System of Air Conditioning Equipment Inspection Robot

A template matching is a popular method for visual recognition. It costs much time to detect target objects. We have applied a Fuzzy and Neural Network algorithm to solve this problem. However, the problem to mistake recognizing the target object is not solved. Hence, in this paper, we propose a robust visual recognition algorithm for the autonomous robot navigation. The proposing algorithm emp...

Hierarchical Hybrid Control for Innovative Air-conditioning Equipment

This paper describes the control system for innovative air-conditioning equipment, in particular an air treatment unit. The most important characteristic of the equipment is to be “friend of the environment”, in the sense that it does not use environmentally aggressive refrigerating fluids. Other main characteristic is associated with the complexity of its control, due to the large number of in...

Improving Equipment Maintainability via Alarm Threshold Optimization

The Operations Technology Center (OTC) is responsible for the systems used to manage and maintain the AT&T long distance network. In this paper we describe an effort within the OTC to improve the maintainability of AT&T’s 4ESS switches, by optimizing the thresholding rules within the operation support system responsible for maintaining these switches. This optimization task required us to firs...
