The new RoHS directive requires more information and conformity checks than the first RoHS legislation. In order to issue the declaration of conformity for CE marking, the technical documentation must proof the device's compliance with the substance bans. According to the REACH regulation, suppliers of articles have to inform professional clients and consumers, the latter only on request, about substances...
According to the characteristics of GSM-R(Global System for Mobile Communications Railway), the Vehicular GSM-R Field Strength Testing System is required that the functions of receiving the data of GPS and displaying related geographic information that has processed and GSM-R field strength testing data situation on the electronic map. For these purposes, the implement program that geographic information...
For an investor, it is important to assess the financial condition correctly of the enterprises that will be invested. The paper uses the improved data envelopment analysis (DEA)-rang adjusted measure(RAM) model to make financial assessment for twenty-four Chinese auto enterprises, it is helpful to make decisions for investors.
At the moment experiments with the use of cognitive radio are performed in a number of countries. However, there is a considerable degree of uncertainty regarding the potential application of cognitive radio. For successful use of cognitive radio, there is a need for cooperation between the technological developments, the market players and the regulator to reduce these uncertainties. In this contribution...
This article details the current work status of the ETSI Reconfigurable Radio Systems Technical Committee, positions the ETSI work with respect to other standards efforts (IEEE 802, IEEE SCC41) as well as the European Regulatory Framework, and gives an outlook on the future evolution. In particular, software defined radio related study results are presented with a focus on SDR architectures for mobile...
Based on the continuous ordered weighted geometric (C-OWG) operator, a new algorithm is proposed to derive the weights from interval reciprocal comparison matrices. The obtained weights are dependent on the corresponding expected reciprocal comparison matrix associated with an attitudinal character. In order to make the weights be reliable, a method of making the expected reciprocal comparison matrices...
This study not only applies Multi-Criteria Decision Making with Incomplete Linguistic model (InlinPreRa) and uses horizontal, vertical and oblique pairwise comparison algorithms to construct but also expansion group decision making model. When the decision maker is carrying out the pairwise comparison, the following problems can be avoided: time pressure, lack of complete information, the decision...
Potential supplier selection has been essential for manufactories to ensure the smooth operation of the production process. Reuven used the analytical hierarchical process to rank three foreign suppliers based on four criteria of supply risk assessment. The analytical hierarchical process uses n(n -1)/2 judgments in a preference matrix with n attributes, while the consistent fuzzy preference relations...
By Directive on RoHS, the use of six hazardous substances is restricted to new electrical and electronic equipment put on the market in Europe from 1 July 2006. The estimation of the type and the content of brominated flame retardants is necessary in plastics of the equipment and the parts. The new technique by using time-of-flight secondary ion mass spectrometry (TOF-SIMS) is proposed for rapid screening...
