This paper presents the tests of a telemetry system (T-SADA) to be adapted to the management of agricultural mechanization using a self-propelled combine harvester to harvest soybeans and rice. The system consists of collecting and sending data of a moving point (a farm machine) to a fixed base (a computer server) and makes the integration of two means of transmission and validation of data (providing fault tolerance). The means of data transmission used were the technology of mobile telephony, GSM / GPRS and radio frequency through the Zigbee. The T-SADA is redundant because it has more than one form of transmission, which ensures the transmission of information even if a media is not able to operate correctly at any given time. Priority is given to the transmission GSM / GPRS and leaving the ZigBee as an alternative means, controlled by an engine fault detection. The results were satisfactory ensuring the transmission of data with fault tolerance and redundantly in remote locations and in different relief. [ABSTRACT FROM AUTHOR]

Distance Learning requires a transmission system and teaching strategies appropriate to the different technologies used. The didactic strategy of distance learning means choosing methods and structured instructional means to produce effective learning. The objective of this paper is to present reflections on distance learning and information and communication technology (ICT) in education, as well as provide an exploratory research to better define the problem, to improve the understanding of distance learning and the use of ICT's. In the exploratory research, with nonprobability sampling, data were obtained through a semi-structured questionnaire, developed electronically. Distance learning provides individuals with training and re-training. However, it is necessary to create conditions to improve communication between students, students and tutors, and students and teachers in the learning environment as demonstrated in table 3, and the media, as demonstrated in Table 4.
