The Possibility of Using RFID System to Automate and Integrate the Attendance of Professors and Students in the Classroom

One of the most important goals followed in most systems is to increase efficiency, reduce errors and enhance ease of data entry tasks such as better services in organizations. Therefore, the use of intelligent tools is of the most important requirements for a management system in order to collect complete and accurate data and create complete information. In management, use of new technologies is recommended to have smart systems and reduce human errors. This study aimed to investigate “professors and students attendance system using RFID” and research population consists of professors and students. Findings show that, as attendance checking system in universities and schools is done through the class list and checking attendance of students needs to spend time and energy so it leads to a waste of valuable time and energy of professors to teach. Therefore, it is essential to use efficient and modern systems, because with the design and implementation of RFID attendance system and replacing the traditional system, time and energy waste could be avoided and attendance system could be promoted to an intelligent and integrated one. The designed system includes a number of hours of presence and absence, delays and rush to pay the salaries of professors at the University with its automatic identification through radio frequency. This system aims to create changes in this area and it is economic in whole.

The Design and Management of Intelligent Systems in Mechanical Domestic Water Meters

The design and implementation of mechanical domestic water meters in current industrial organization and intellectual properties have been registered as an invention to solve the problems of current meters. The device operation includes inquiry of printing, subscription connection and disconnection in an emergency. This system includes a software and hardware parts on the users and the control center connecting with two-way mobile phone. Central control software sends the message through the wireless telecommunication lines to the user’s software, requesting the desired information and also provides the commands needed to be sent through the same. The same information can also be submitted to the control center. Through the same way, some of advantages of this method are as follows: installing on existing meters, cheap cost of inquiry call meter, the possibility of declaring illegal manipulation to the control center, the exchange of information using information encoding, and manipulating digital meters applying minor changes.

The Analysis of Spring Precipitation in Semi-Arid Regions: Case Study in Iran

In this study, Zanjan from Iran has been chosen from among all the semi-arid regions of world, which has Synoptic station and statistical data since 1955. Spring and monthly precipitations are also provided in the period of 1956-2005. First, all data has been controlled by double mass method with the help of adjacent stations, and then it was normalized by the box-cox transformations method. The global SPI index was calculated for all months and spring, also drought and wet periods were determined and finally compared. In the drought category view, spring months have represented the great similarities. The moving averages are represented all months and spring’s precipitations such as three years, five years, seven years and nine years are shown. Statistical period was observed and analyzed based on five periods of ten years, and results precipitation with more than 5mm and 10mm has gradually decreased on April. However the number of days with precipitation has increased. The calculated spring precipitations and all of the atmospheric factors represented the dependence of this model to maximum average of spring temperature and relative humidity of spring and winter by the use of multi variable regression method. The predicted precipitation of spring also showed the gradual decline of precipitation in the next 30 years by the arima model.

The Design and Construction of an Intelligent Taxi Electronic Payment System Solution

Today the usage of electronic services in different taxies seems to be necessary. Organizing a system to pay the taxi electronically with the card by the passenger can decrease the need to carry cash. Designing and building of such a system by using a special taximeter with new features and also one or more card reader can be fixed into the taxi. Payment is with the smart credit card and from the client's account. The information of presented services is stored in the system and will be recorded as offered services. The driver can have access to taxi organization or some special terminals electronically to see his account and also he can receive a receipt.
