This contribution deals with some remarks and hints that could help in the solution of the common question how to conceive and arrange the laboratory exercises on the measurement tasks that are too complex that there is not enough time to introduce, comprehensively explain and practice during laboratory exercise. As an example of such task, the measurement of voice transmission quality of service (VTQoS) in modern telecommunication network (e.g. GSM) is chosen.

A rule based expert system (ES) has been implemented, which acts as a tutor to measurement scientists and technicians (metrologists) in the calculation of the uncertainty of measurements according to the methodology of the ISO "Guide to the Expression of Uncertainty in Measurement" (ISO Guide). The ES was implemented with the expert system shell/inference engine, "VP-Expert" (VPX) running in a DOS window. The intended target users are experienced metrologists, who lack the mathematical skills and concepts, particularly in statistical and sensitivity analysis, to implement the ISO-GUM document correctly. The ES guide uses seven main knowledge bases with a total of about four hundred rules. It allows a full, guided evaluation of the uncertainty of a measurement and uses a text-based tutoring knowledge base which is accessed either in a generic browse mode, or a context-sensitive mode based on the status of the current calculation. The ES uses background variables to maintain a consultation across knowledge bases and between interrupted sessions. The software implementation of this training is used as an analytical tool to make explicit and systematically specify the categorization and structure of the ISO Guide's fact-based and process-based knowledge content.

The big number of management methods has more than 200 expressions with different names. In alphabetical order one can start with ABC management, the abbreviation for adaptive, bioregional & cooperative management [www.orst.edu/instruction] through Theory Z management for the improvement of human resource management [www.an.af.mil/database/research].
Measurement, Instrumentation & Test Management MTM is a newcomer to management science and practice as well as to education & training. The mission of MTM is to bridge the gap between the rigid framework of measurement engineering on the basis of legal metrology and the more experienced daily measurement, instrumentation and test practices.
The purpose of the paper is to provide answers to the questions:
- WHY do we need MTM
- WHAT is MTM
- WHAT are MTM standards
- WHAT to do in MTM education.

Interconnected sensor nodes can be used for a long term monitoring of widely spread ecosystems. Individual nodes can be unavailable during the runtime due to a lack of energy, disruption of communication channels, or physical damages of nodes. In this paper, a new approach to transfer messages from nodes to gateways (and optional to flood gate nodes) in such dynamically disturbed networks is presented. The focus is the routing in branched line-structures, e.g. flood barriers. The usage of gradient structures in each node allow tree routing, tree propagation, energy-efficient exploring broadcast, exploitation of line-structures, and collection of position information. Additionally, a generic preference evaluation and decision making concept allows energy or signal quality evaluation, routing decision, structure setup decision, position estimation, synchronization adaption, and randomization of security approaches. It can be extended by further rules.

Precision Farming (PF) involves parameters monitoring related to different agricultural systems. This control is mainly based on intelligent techniques such as Wireless Sensor Networks (WSN) which can provide periodically data reports via the wireless communication relating sensor nodes to each other. However, sensor nodes are energy constrained and limited to their remaining battery power. Therefore, prolonging their lifetime is consequently an issue to be highly considered. The communication between the nodes including transmissions and receptions is the major source of energy waste. The purpose of this paper is to design an energy aware routing algorithm for a WSN deployed in an agricultural system. This algorithm takes in consideration the requirements of a typical PF system and merges them with power management techniques to get the nodes’ lifetime extended.
