As dimension shrinks in advanced technology nodes, the critical dimension (CD) plays a critical role and so does QTime. Front Opening Unified Pod (FOUP) door closure, delaying FOUP door opening, introducing N2 Purge and creating vacuum at optimum steps and for optimized duration has shown promising results in extending QTime and improving yield. Etch is often performed by reactive ion etching (RIE)...
Flexible benefits cannot be ignored in the promotion of the employee's work well-being. On the basis of introducing the concept of flexible benefits and work well-being, this paper analyzes the relationship between flexible benefits and work well-being, and proposes the research hypothesis, establishes the theoretical model, and takes the new generation staff as the research object, and uses the method...
The decreasing size of solder joints leaves limited tolerance of allowable warpage range for successful assembly. Understanding the electronic packages' behavior during the reflow process becomes one of the most important tasks in developing assembly process and assuring reliability. Three-dimensional (3D) digital image correlation (DIC) plays an important role in quantifying warpage of BGA packages...
The costly explicit and implicit acknowledgements (ACKs) are issues that need to be addressed in the existing reliability aware flooding algorithms. This research focuses on energy efficiency on both data transmission and ACKs, while achieving target reliability and balancing the residual energy of sensor nodes. A correlation-based probabilistic flooding algorithm (CPFA) is proposed. It exploits the...
The unique tail bits retention failure behavior is observed in the RRAM array. Unlike the previous reports on single device or the average value''s retention behavior, quick retention loss of tail bits is found for both LRS and HRS. By statistically characterized such relaxation effect of tail bits, physical models are built to quantitatively describe the relaxation behaviors of LRS and HRS. The correlation...
A novel approach for estimating variation in the TDDB failure time is reported. The results for structures with Dual Damascene copper-based metallization and a low-k dielectric material demonstrate that variation in the initial current at stress reasonably predicts variation in the TDDB failure time. Moreover, the method does not cause failure in the structures and is more efficient compared to other...
Computationally efficient design optimization of antenna structures can be realized using variable-fidelity EM simulations, where most of the operations are performed at the level of a coarse-discretization EM model (referred to as the low-fidelity model) with occasional reference to the high-fidelity one, for the sake of model correction and design verification. An important issue is an appropriate...
This paper compares the performance of single pseudo-noise (PN) and dual PN (DPN) sequences for time of arrival (ToA) estimation in underwater acoustic (UWA) localization. The single PN scheme uses the correlation of a local PN sequence and the received PN signal to estimate the ToA. The DPN scheme utilizes the cross correlation of the two received PN segments in one signal frame to calculate the...
Virtual RINEX (VR) is a common product for Global Navigation Satellite System (GNSS) post-processing applications, useful if the distance between the rover and master is greater than 30 km. Many studies have been conducted in order to analyse the content of this kind of data, but few have proved the positioning performances obtainable in particular conditions. The VR is a synthetic file created from...
In order to help system (transmission and/or distribution) operators to account for the stochastic nature of wind during the grid planning phase, univariate AutoRegressive Moving Average (ARMA) time series models for the long term modeling of wind speed are generally considered. Practically, different geographical correlation levels are observed in the bibliography when sampling wind generation in...
In this information age, Social Networking Services contribute a significant amount of contents in creating a knowledge based society. Nowadays, there are more than 500 million tweets sent per day in Twitter. Such drastic growth of contents brings new opportunities for human beings to discover their surroundings more effectively in a timely manner. Moreover, these types of services evolve not only...
By the methods of questionnaire and interview, the study investigates 395 non-English major college students self-efficiency, achievement goal orientation and self-regulated learning strategies, through correlation analysis and multiple regression analysis, analyzes the effects of individual factors on college English learners autonomous learning ability. The results show that individual factors,...
We present a system for predicting gaming-related properties from Twitter profiles. Our system predicts various traits of users based on the tweets publicly available on their profiles. Such inferred traits include degrees of tech-savviness, knowledge on computer games, actual gaming performance, preferred platform, degree of originality, humor and influence on others. Our approach is based on machine...
The wireless sensor network is a collection of programmed sensor nodes spatially distributed to monitor environmental conditions. Reprogramming is essential to update the changing requirements and also to fix the bugs in sensor nodes after it is deployed in a hostile environment. It is impossible to manually reprogram the sensor nodes once it is deployed. Hence, the sensor nodes are reprogrammed remotely...
Insurance data processing system used by PT. Asuransi Takaful Umum is a system Care Tech. Care Tech System is a system designed for general data processing such as vehicle insurance, fire, property, and others with a web-based base that can be accessed online. During implemented since October 2013, Care Tech system has not been evaluated in terms of user acceptance. The purpose of this study was to...
There has been many studies carried out on virtual banking adoption, but studies carried out in Malaysia to enhance the virtual banking strategy adoption are limited. Therefore, the objective of this study is to conduct the conceptual model of virtual banking strategies and to find out the key determinants of virtual banking strategies in achieving customers' loyalty in Malaysian perceptive by using...
In order to structure the complex nature of the significant wave height time series, Autoregressive Integrated Moving Average model of order (p,1,0) was applied. Each step which is essential for precise modeling is covered comprehensively. First, the stationarity of given time series of SWH with its 1st order difference were checked. Akaike's Information Criteria and Bayesian Information Criteria...
Maintainability is an important product quality attribute that has significant influence on operational effectiveness and lifecycle cost. It is emphasized that maintainability has to be designed into product and standards or handbooks were developed to guide how the maintainability engineering is implemented. However, how to design product to meet maintenance needs is not explained clearly. Only some...
Functional and Interface Failure Mode, Effects and Criticality Analyses (FMECA) investigate the following types of detailed potential failure origin and failure impact questions: • What interfaces dependencies or performance issues exist as a result of each potential functional failure or input loss? • If a component fails or exhibits intermittent functionality, is a redundant component available...
The readiness and support for self-directed learners in using blended learning is still lacking despite the growing number of innovations and creations for new technologies. Thus, there is a need of empirical study to assess the driving factors of m-learning adoption for the self-directed learners. The main objective of this exploratory study is to investigate the relationship of the factors that...
