The architecture of a software-driven testbed is discussed. The test setup has been developed as measurement and instrumentation system to functionally verify and thermally validate the communication subsystems designed and manufactured for the nanosatellite applications. The system is applied for qualification of a communications subsystem currently under consideration for ZA-CUBE-2 mission.
This paper is concerned with event clustering for short text streams, which aims to divide constantly arriving short texts into several dynamic event-based clusters. A widely adopted approach is based on the Vector Space Models (VSMs) such as bag of words. However, these models have limitations in that not only the semantic relationships between words are largely ignored, the term weighting may also...
The task of the Evaluation of Machine Translation (MT) is very difficult and challenging too. The difficulty comes from the fact that translation is not a science but it is more an art; most of the sentences can be translated in many acceptable forms. Consequently, there is no such fix standard against which a particular translation can be evaluated. If it has been possible to make an independent...
The paper presents analysis of the results of 873 template measurements used for inspection in wagon depo. The data obtained were analyzed to confirm the stability of inspection results. It is shown that the measurement and determination of the final result by calculating the average value lead to misleading results. Random factors affecting measurements are also presented. The subjective factor in...
Industrial networks represent an important business for automation systems manufacturers that offer proprietary solutions and claim for the payment of license fees. However, automation can be achieved even by exploiting standard protocols in order to avoid or limit the use of proprietary solutions. The considered case study, related to the innovation of an oil refinery, illustrates a viable approach...
This paper describes the determination of temperature coefficients of the standard inductors manufactured by GR (Type 1482) from different methods and their comparison. The standard inductor has been measured using precision LCR meter for 24 hours in controlled and stable environment. The temperature coefficient has been determined from 23 °C to 27 °C. This is the extension of the previous work done...
Putting robotic automation to work in a mid-nineties vintage 8” wafer fab is without a doubt a challenging maneuver. Therefore it is not at all surprising that any rigorous project scope puts all its momentum into getting the robots automatically moving wafers based on the existing standard workflows — in other words — executing the non exceptional everyday workflows. In the case of manufacturing...
