- Practical Skills Training in Computer Education
Abstract: Practical Skills Training in Computer Education
Author Jun LiuLi H
Practical skills training is more important than ever in current computer education. Since traditional teaching mode is hard to meet the requirements of IT enterprises, it is imperative to make teaching reform. We improve our experiment teaching by revising the experiment curriculum, and put forward an open experiment teaching model. We set up a training base in collaboration with industry and work out the operation and management of university-enterprise cooperation mechanisms, including the training base, teaching management, student management and teaching staff. It lays a solid foundation for the innovation of computer professional education.
- A New Noise Mitigation Scheme in Power Line Communication Systems Based on
the Principal Components Analyses
Abstract: A New Noise Mitigation Scheme in Power Line Communication Systems Based on the Principal Components Analyses
Author Jiang-Qian L
Power Line Communication (PLC) systems suffer from too severe noise contamination in the channels. In the paper, a new scheme was proposed based on the principal components analyses (PCA) to mitigate noises in PLC channels. The scheme consists of four steps. In the first step, the PLC signal with one dimension is generalized to a data set with multiple dimensions (degrees). In order to de-correlate the new data set, generalized signals are whitened with Gaussian noises in the second step. For the uncorrelated data set, the PCA technology is applied to cancel noises in the transformed domain. As the last step, the PLC signals of interesting are recovered by applying the inverse transform matrix. The results from the simulated seismic signals and the measurements data verify the validity of the proposed scheme.
- A Framework for Knowledge Sharing of Enterprise Resources
Abstract: A Framework for Knowledge Sharing of Enterprise Resources
Author Hamed FazlollahtabarBabak ShiraziAdel Porramezan Ganj
In this paper, a framework is developed to manage knowledge sharing on enterprise resources. Enterprise resources are the key elements to progress business objectives. We propose a switch mechanism to handle knowledge sharing in a business. To integrate value chain in a business comprehensive data flow is significant where knowledge sharing is a structured for this process leading to better service provision for customers. Also, a knowledge development program is proposed to evaluate the proposed knowledge sharing switch. The validity of the proposed process is shown in a case study.
- Shape Verification of Fused Deposition Modelling 3D Prints
Abstract: Shape Verification of Fused Deposition Modelling 3D Prints
Author Andrej CuparVojko PogačarZoran Stjepanovi
In this article, the shape of fused deposition modelling (FDM) 3D printed testing objects is verified with 3D scanning technique. Leapfrog’s Creatr is used as a manufacturing device. The whole process of a materialization is explained – from preparation of a model to preparation of a printer. The study is meant to evaluate dimensional errors of printed parts and to give some advices on how to minimize them.
