Estimation of route-level travel time distributions (or travel rates) from segment-level data is of great interest today. This paper shows how the random variable properties of comonotonicity and independence can be used in combination to develop such distributions for a wide range of operating conditions. Efficacy of the technique is illustrated using Bluetooth-based travel times collected from individual...
The increased consumption of wine in Indonesia is clearly visible due to the increasing number of outlets that sell wine following the economy growth in Indonesia. The purpose of this research is to analyse the effect of product, price, place and promotion to purchase decision in DKI Jakarta and Tangerang. This research using quantitative method, number of respondents involve in this study are 150...
With the improvement of China's international influence, more Chinese words are borrowed into English. To find out how popular Chinese borrowings in English, a questionnaire is conducted among English speakers (Chinese natives are excluded). Swaan's Q-value model is hereby employed to analyze the data. The result shows that Chinese borrowings in English vary in Q-value and the ones related to economy...
In this paper, a target sound enhancement method using two microphones under a nonstationary noise environment is described. In the method, a linear filter is connected to each microphone, and filter coefficients of linear filter are determined adaptively to enhance a target sound. Then, a supervised signal is required for learning the filter. However, the supervised signal is generally unknown. According...
In subjective evaluation of dysarthric speech, the inter-rater agreement between clinicians can be low. Disagreement among clinicians results from differences in their perceptual assessment abilities, familiarization with a client, clinical experiences, etc. Recently, there has been interest in developing signal processing and machine learning models for objective evaluation of subjective speech quality...
The notion of subjective image quality (SIQ) is particularly difficult to define as it depends on a large variety of physical attributes and psycho-physical factors. One important attribute which SIQ depends on is the illumination under which visual stimuli are observed. Recent studies have shown that achromatic fidelity (i.e. perceived resemblance in lightness) is significantly less dependent on...
Information and Communication Technology (ICT) has changed the world scenario including business and economies. There are new opportunities and challenges for every country to produce knowledge oriented citizens. Driven by these changes, numerous higher education institutions around the world are integrating and adopting latest ICT tools to deliver quality education. However, the Effectiveness of...
A stochastic production simulation model was developed to evaluate the California Independent System Operator (CAISO) system capacity and flexibility sufficiency in order to integrate high volume of renewable generation to meet the California state renewables portfolio standard (RPS) goals. The model, which simulates the operation of the CAISO system, uses four stochastic variables, generation resource...
This paper describes the adaptation and validation of an instrument aimed to determine self-regulation skills, learning strategies and affective strategies of engineering students from the Tecnologico de Monterrey, Mexico City Campus. A statistical validation with Cronbach's alphas and a social validation in which students indicated whether or not they agree with their results on each dimension were...
One of the main challenges of current person recognition techniques lies on difficulties of recognition in various poses. Recently, attention has been focused on using soft biometric information extracted from the human body to overcome the biometric recognition system's limitation in unconstrained environments. In this paper, we integrate the face and body information in a linear combination. We...
Objective of the paper is to evaluate metrics of automatic evaluation of machine translation output using manual metrics — fluency and adequacy. We tried to answer the question to which extent the manual evaluation correlates with the automatic evaluation of MT output from/to Slovak to/from English. We focused on metrics based on the similarity and statistical principles (WER, PER, CDER and BLEU-n)...
In response to customer's demand enforcement, marketers need to carefully select the best marketing campaign. Marketers are creating a contest campaign that requires the participant to upload photos or videos via social media. Interdependent self-construal is one's perspective in which people are somehow connected in a social context. The technology acceptance factors, consisting performance expectancy,...
The purpose of this study was to investigate the reliability and validity of the U-shape electronic walkway (USEW) in assessing gait variation in persons with Parkinson's disease (PD). Gait parameters from the straight part and corner part of the USEW were calculated and compared. Most of the gait parameters in PD group were significantly different as compared with that in the healthy elderly (HE)...
The core vision of the smart grid concept is the realization of reliable two-way communications between smart devices (e.g., IEDs, PLCs, PMUs). The benefits of the smart grid also come with tremendous security risks and new challenges in protecting the smart grid systems from cyber threats. Particularly, the use of untrusted counterfeit smart grid devices represents a real problem. Consequences of...
Every student has different learning styles. They have tendency in perceiving, interacting and processing information they have learned. Those tendencies can be identified by assessing stodente' learning styles using the Index of Learning Style (ILS). ILS is commonly used to identify engineering student's learning style in learning personalization system. However, this questionnaire is developed in...
Fundamental transformation of the healthcare sector through informatics is achievable, from technical prospective. However, organisational issues surrounding technology implementation in healthcare setting have not yet received adequate research attentions in developing countries. The aim of this study is to develop a conceptual framework model to determine Telemedicine Readiness (TR) at an organisational...
The purpose of this study is to investigate the intention to use the cloud sphygmomanometer in Taiwan. This study also aims at providing suggestions on the popularization of cloud medical services. This study was established in a way that the model constructs in Technology Acceptance Model (TAM) were adapted to the context of cloud sphygmomanometer application in health management. Scale items on...
Building brain networks based on functional Magnetic Resonance Imaging (fMRI) signal is one of the efficient methods to study functional connectivity of human brain. Various methods of constructing brain network will lead to different results. It is wondered which method is reliable. Therefore, it is necessary to set up a synthetical framework of brain network analysis to study the functional connectivity...
In this study we investigated the effect of mastery confidence manipulation on BCI performance and P300 amplitude. We used a 6×6 P300 speller matrix and participants spelled words containing five letters each. Using a cover story, thirty-six participants were misinformed that they would use classification algorithms of diverse difficulty in three experimental blocks (easy, medium, hard condition)...
Reliability analysis based on failure mechanism takes advantage of unnecessary requirement for the field data, compared with the traditional method based on probability statistics. Current reliability analysis for systems based on failure dependence mainly focus their views on either failure level or failure process level, but barely from the aspect of failure mechanism. Our previous work used Mechanism...
