In these days, the civil appeal and dispute about environmental noise grows larger every year. But there are not suitable systems for measurement and management of environmental noise. This paper proposes environmental noise measurement, characteristic analysis and evaluation, management system using Internet. We can measure and manage the environmental noise also, analyze characteristics of noise by the environmental noise management system using Internet.

Cloud services are often provisioned to their customers using user-friendly web browsers with flexible and rich plug-in environments. Delay is one of the fundamental performance metrics of these web-based services. Commonly-used network measurement tools usually only measure network delay and it may be difficult to infer the web-delay performance using only network layer measurement approaches. In this paper, we propose to evaluate the application layer delay in a browser-based network measurement platform using engineered scripts. We conducted a delay measurement study using instrumented scripts in the proposed browser-based measurement platform. Our investigation included a comparison study of three browser-scripting delay measurement methods, including Java applet, JSP and Flash ActionScript. We developed a browser-based delay measurement testbed over the Internet so that different delay measurement tools could be evaluated in the same real network environment including typical Internet paths and the Baidu cloud. We also decomposed the components of the end-to-end delay process of the above measurements to reveal the difference and relationship between the network-layer delay and the application-layer delay. Our measurement results characterize the stochastic properties of the application-layer delay over real Internet paths, and how these properties vary from the underlying network layer delay. This browser-scripting measurement approach can be easily deployed on different cloud service platforms to inspect their application-layer delay performance between end clients and the cloud platforms. Our measurement results may provide insights into designing new cloud services with enhanced quality-of-experience perceived by cloud users.

Recently, the severe competition in the internet shopping mall has forced firms to increase the customer satisfaction and to enhance service quality Despite the internet shopping mall's fast and superficial growth and extraordinary potential, study on (actors affecting service quality based on its characteristics is meager. Most researchers have studied on the service quality related with the internal shopping mall by just applying measurement items in internet environment. This paper tries to analyze whether the internet shopping mall can be reorganized by introducing factors of service quality specifically with reference to the internet showing mall. In addition, this study focuses on developing the method to measure the service quality more effectively. For this purpose, this study applies the Taguchi Method using quality loss function (QLF) which can be used to measure quality quantitatively. The proposed method provides the measurement of the internet shopping mall's service quality and offers to the practitioner a measurement tools suitable for service industry.

In this paper, we have developed a system for monitoring and processing the real time sensor data in remote site through Internet. For realizing this system, measurement equipment and protocol are used to transmit the measurement data to remote server and to process measurement data. In server part, the received data from remote site sensor is converted to text or graphic charts for user. The measurement device in sensor part receives the sensor data form sensor and store the received data to its internal memory for transmitting data to server part through Internet. Also the measurement device can receive data form server. The temperature sensor is corrected to the measurement device located in laboratory and the measurement device measures temperature of laboratory which can be confirmed by user through Internet. We have developed a server program working on the Linux to store measurement data from measurement device to server memory. The program is use for SNMP(Simple Network Management Protocol) to exchange data with measurement device. Also the program changes the measurement data into text and graphic charts for user display. The program is use apache PHP program for user display and inquiry. The real time temperature measurement system can be applly for many parts of industry and living.

This paper is concerned with the development of remote control and measurement systems system using the internet. Recently, various techniques are developed based on the advance of the internet environment. In this study, we developed the remote control and measurement system using the internet server programming technique, stepper motor control and the data acquistion programming techniques. Hence, we can perform measurement and control remotely. The feasibility of the system is validated using the experimental setup. A personal computer is equipped with the stepping motor controller which control the weight and the A/D board which measures the strain of the beam, server program was then installed on the PC and can be accessed through internet.

This paper is concerned with the development of remote vibration measurement system using the internet. Recently, various techniques are developed based on the advance of the internet environment. In this study, we developed the remote vibration measurement system using the internet server programming technique, the client programming technique, the GPIB programming, and the A/D, D/A programming techniques. Hence, we can control the measurement devices remotely. The feasibility of the system is validated using the experimental setup. The output of the D/A is connected to the small exciter and the piezoceramic sensor is connected to the A/D port. By sending out the exciting signal to the structure, we can collect the response. The experiment shows that the proposed idea works well. Another experiment consists of the function generator and the low-pass filter circuit. The wave form, amplitude, and the frequency of the function generator is controlled by the GPIB program and the output of the circuit is collected by the A/D port. The output is then displayed in HTML format.

Recently, according to development of information-oriented society, internet application technology on electricity electron controled technology fields are diversified and the necessity of remote measurement by internet is gradually increased. In this paper, to meet in these necessity we design and implementation of remote measurement system using internet embedded module, which was developed for on-line measurement of various kinds of analogue data. This system is consisted of two parts greatly, hardware module for measurement and software module to control it. The advantage of this system is that users can acquisition the remote data of temperature and illumination etc. without extra serve pc easily. In order to test the validity of the proposed system, we examine the response and operating characteristic about several states. As a result of the test, we proved the effectiveness of it.

As the number of IP-users are increasing, it is getting so important for service providers to check the state of the current Internet and their service quality by measuring the traffic quality. We describe a general concept of measurement architecture and internet QoS (Quality of Service) parameters, and we review measurement tools. To meet these requirements, we design and implement the Internet traffic management system.
