One of the main factors for developing a well functioning legal background for the use of electronic documents as evidence in the court is the presence of a reliable timestamping infrastructure. Many countries are currently working on their national digital signature law. The current paper emphasises some of the problems arised during the work of the committee formed by Estonian State Chancelle...

Prevention is better than cure is not only applicable to medical domain but also equally applicable to engineering field. By analyzing the symptoms and taking appropriate corrective measures before the actual failure takes place would avoid costly cateroscopic damages. In line with this approach a fault analysis through vibration study with wavelet transforms has been attempted in this study. T...

Conventional diagnostic methods applied to industrial induction motors, such as the motor current signature analysis, may lead false-negative outcomes in several cases. Such a case consists of nonadjacent rotor breakages occurrence. Various alternatives with advanced digital signal processing algorithms have been proposed that concern monitoring and analysis stator current, or stray magnetic fl...

about electronic signatures there are more or less some writings concerning their legal aspect. but in those writings there has been a little attention to credibility and evidential value of the electronic signatures. some questions and ambiguities despite being set before has not been answered at all or answered unsatisfactorily. meanwhile, some authors have made mistakes and some have set tri...

[Purpose] This study investigated the effects of types of electrode on N100 and P300 in transcranial direct current stimulation (tDCS) applications. [Subjects and Methods] Thirty subjects were randomly assigned to two groups with 15 subjects in each group depending on the electrode types. A positive electrode on the primary motor area (C4) and a negative electrode on the left primary motor area...

Convergent findings point to a left-sided specialization for the representation of learned actions in right-handed humans, but it is unknown whether analogous hemispheric specialization exists for motor skill learning. In the present study, we explored this question by comparing the effects of anodal transcranial direct current stimulation (tDCS) over either left or right motor cortex (M1) on m...
