Eddy current testing (ECT) has three main tasks: detection, location, and characterization of defects. The characterization task, which means the ability to find the geometrical characteristics of the defect, is still in the research domain, although in many industrial applications this task has to be carried out with good accuracy to allow reliable acceptance or rejection decision indispensable to...
To support development processes for nanodevices, we want to utilize the information related to experiments from nanodevice development research papers. In this paper, we propose a new guideline for constructing a tagged corpus of nanodevice development papers to achieve this goal. We also propose the use of a corpus construction support tool. To speed up the construction process, we propose an approach...
In China, more and more companies are constructing internal control system as enterprise internal control basic standard (EICBS) was released last year. Based on the data obtained in a survey, we firstly examine the quality of internal control in China companies. Secondly we examine how and to what extent the firm-specific characteristics determine the quality of internal control. We find that size,...
In the last years the development of learning environments, and particularly of educational adaptive hypermedia (EAH) systems has increased significantly. However, it is important to complement this development with evaluation methods in order to improve EAH system performance. In this context, we propose to analyze the data from student interaction with EAH systems utilizing the GeSES method. This...
The Package on Package (PoP) component is getting attentions in mobile communication electronics industry to meet the miniaturization requirements. The 3D IC packaging technology is employed to achieve higher integrations for multiple functions. This also concurrently reduces the size of PCB during second level of interconnection. Currently, there are two major approaches for system manufactures....
Quality Function Deployment for Environment (QFDE) is an effective eco-design tool to consider Voices of Customer and Environment (VOCE) simultaneously. VOCE are related to some engineering metrics with proper weights through House of Quality in QFDE. Then the engineering metrics ordered by the weights are used into product eco-design for evaluating environmental effect or advancing some design improvement...
Based on employee retention research and social resources theory, this paper proposes a construct of motivation to protect existing resources, the purpose of which is to develop and validate an instrument measuring the construct, in order to indicate the motivation mechanism behind the predictors in employee retention research. The paper develops a three-factor structure scale to measure the motivation...
Two-dimensional RAID arrays maintain separate row and column parities for all their disks. Depending on their organization, they can tolerate between two and three concurrent disk failures without losing any data. We propose to enhance the robustness of these arrays by replacing a small fraction of these drives with storage class memory devices, and demonstrate how such a pairing is several times...
Most of current research focuses on students and how technology affects them, but less has been done to describe the role of the teachers, especially in the context of E-education. The paper is to find the way to solve the problem. This study finds that firstly, Students need their teacherspsila help both psychologically and technically in the context of E-education. Secondly, itpsilas the teacherpsilas...
Reliable RFID identification is one of issues in RFID applications in recent. However, the RFID reader has difficulty to obtain reliable data in data capture layer. The reason is that unreliable readings such as a false positive reading and a false negative reading and missed readings can happen by reader collision problems, noise, or the mobility of tagged objects. We introduce performance metrics...
Outsourcing logistics business can improve core competition of enterprise. So it is of vital importance to evaluate logistics service quality. Fuzzy Comprehensive Evaluation Method is an effective method. In this paper, we take logistics company M as studying object. We construct evaluation index and mathematic model. By quantifying index and calculating, we conclude that the service quality of logistics...
The damage of structural safety of concrete is very large in harsh environment. Various properties of concrete can be improved by daubing protective agent on the surface of concrete. Influence of the protective agent on the impermeability and frost resistance and compressive strength of concrete is analyzed and determined by establishing experiment model and selecting protective agent. It is shown...
A basic part of the logistics management in companies is the purchasing function, and the appropriate selection of vendors is one of the prime responsibilities of this function. Many conceptual and analytical models have been developed for addressing the vendor selection problem. While it has been recognized that vendor selection is multiobjective in nature, litle has been done to develop techniques...
A novel test structure based on a planar capacitor design has been used for advanced barrier material evaluation and process optimization. This structure enables intrinsic reliability study of Cu/low-k interconnects. Various barrier materials such as CuMn self-forming barrier, ALD Ru, and PVD TaNTa on different dielectric films have been investigated to understand their intrinsic limits of barrier...
A novel test structure to study intrinsic reliability of barrier/low-k is proposed. The structure is based on a planar capacitor design where low-k film is deposited after the patterning of the capacitor, followed by metallization and Cu CMP. This so called low-k planar capacitor structure provides several unique capabilities to study various aspects of barrier/low-k TDDB compared with the conventional...
The proposed method pertains to diagnostics of linear parts of gas distribution and trunk lines. It is based on nanolevel effects on the work surface of pipes. The proposed pipe wall diagnostics technique allows taking consequent analyses reasonably by piecemeal removing and cutting specimen during 20-30 years of pipeline operating time. It ensures the accurate predictive analysis of the pipeline...
According to expansion of the market for portable products such as mobile phone, digital camera and PMP, adoption of WLP for various devices was increasing. Recently, WLP was being applied to higher pin count device as well as lower pin count device. In case that WLP is applied to higher pin count device, various reliability issues are expected from large die size and fine solder ball pitch. The more...
In engineering applications, piezoelectric materials are usually bonded to elastic substrates to form so-called smart materials and structures. Such materials and structures can respond to external electromechanical environments. This article studies a piezoelectric layer bonded to an elastic substrate subjected to static electromechanical loads, both of which are of finite length. A system of differential...
