This paper introduces a novel image quality metric that outperforms other existing and widely used metrics, namely the Root Mean Square Error (RMSE). While objective methods for assessing perceptual image quality to quantify the visibility of errors between a distorted image and a reference image have got utmost importance nowadays, none of the proposed metrics are completely satisfactory. Structural...
This paper presents a methodology for running NGS read mapping tools in the cloud environment based on the MapReduce programming paradigm. As a demonstration, the recently developed and robust sequence alignment tool, BFAST, is used within our methodology to handle massive datasets. The results of our experiments show that the transformation of existing read mapping tools to run within the MapReduce...
The study is a cross-dialect comparison of the vowel systems of different inventories across five Chinese dialects in terms of vowel dispersion and vowel variability. The dialects include Meixian Kejia or Hakka with 5 vowels, Hong Kong Cantonese with 7 vowels, Fuzhou with 8 vowels, Ningbo with 10 vowels, and Wenling with 11 vowels. Formant frequencies were obtained through spectral analysis of speech...
This study focuses on the negotiation in the financial markets, specifically in programming an algorithm to trade automatically (without human intervention) in the foreign exchange market (Forex). The platform used in this study was the Meta Trader (version 5), which allows for this kind of negotiation. The main objective was to conclude about the effectiveness of anewly developed strategy for automatic...
An important method used to speed up forensic file-system analysis is white-listing of files: Well-known files are detected using signatures (message digests) or similar methods, and omitted from further analysis initially, in order to better focus the initial analysis on files likely to be more important. Typical examples of such well-known files include files used by operating systems, popular applications,...
This paper presents a socio-demographic model defined by sexes and structured by age. The model is a von Foerster-McKendrick model for the dynamics of population by sex and age of a general human population. The fertility and deaths rates are structured by age and they depend on the well-being variable. The well-being variable is defined by UN, HDI-Hybrid. We present the validation of the stochastic...
Chair comfort is an important design element of the modern life. in this study, a method based on the signal of posture transform was discussed to predicting subjective perceptions of long-term chair comfort. the signal of sEMG in the procedure of mutual transformation during six representative posture was recorded, then analysis of correlation between the change of subject comfort and the index of...
This paper is to discuss the B2C e-commerce companies' service quality evaluation from the entire service process. It puts three process as the first layer indicators. They are human-computer interaction, human-human interaction and purchase results. At the same time it divides into 17 factors as the second layer. This paper collects data from goods comments about Jing dong Mall and Dang dang. Combining...
The Light fastness is straw crafts surface nature and quality of one of the evaluation. Using spectrophotometer, study of wheat straw surface chromaticity index change for different time periods, in the UVA-340 fluorescent UV lamp 24 +48 × (2.5 +0.5) = 168h. The results showed that : (1) Radiation 156h sample and bleached sample(1% NaHSO3) chromatic aberration ΔE∗ difference value is 4.64NBS, known...
This paper presents an audio monitoring system for detecting and identifying people engaged in a conversation. The proposed method is hands-free as it uses a microphone array to acquire the sound. A particularity of the approach is the use of a laser range finder based human tracker system. The human tracker monitors the locations of people then local steered response power is used to detect the people...
Professional managers evaluation is an essential condition for professional managers marketization which provides objective basis and standards for the shape of selection, inspiration and mechanisms of monitoring. Through analyzing the professional managers' actuality, problems and effect factors in our country, based on the Stakeholder Theory, we explored the training mode of professional managers...
This paper introduces contribution of the thumb sensation to precisions of human's pinching force control when the human cooperatively pinch an object with the exoskeleton, which augments human pinching force based on a surface electromyography. A human hand should contact with a grasping object directly, while the exoskeleton pushes the human hand for grasping support, because tactile feedback from...
The dynamics of collective attention emerging out of individual viewing experiences from public displays appear to be among the most demanding challenges in understanding the mechanisms of self-adaptation of public opinion. In this paper we approach a model of collective attention from observations of the attention of individuals estimated from their efforts expressing interest. Extending on SEEV,...
This avifauna study was conducted at Taman Botani Negara Shah Alam, Selangor, Malaysia on the 17th-18th October 2009. A total of eighteen individuals of birds representing 13 species from 9 families were recorded. Birds were sample by utilizing standard mist nets (dimensions, 2.5 m × 9 m and 3 m × 14 m). The most abundance of species is Lanius tigrinus (Tiger Shrike) and the Laniidae is the most abundance...
We present an automatic human background substitution system based on a Random Walk (RW) algorithm on a multi-core processing architecture. Firstly, a fast algorithm is proposed to solve the large linear system in RW based on adapting the Gauss-Seidel method. Two tables, TYPE and INDEX, are introduced to fast locate the required data for the close-form solution. Then, face detection along with a human...
One of the most important tasks in Human resource management is to find a suitable human for the given position. It is a difficult task because for human beings what they can do well is not always what they want to do and even if they have capability of fulfilling the requested task, the relationship among the team members can prevent them from being the good worker in the given position. Therefore,...
In this paper, we describe Object Pixel Mixture Classifiers (OPMCs) which classify an object not only apart from background but also from other objects based on Gaussian Mixture Model (GMM) classification. The proposed OPMC is different from general GMM based classifiers in the respect that novel pairwise threshold is applied for final classification. Pairwise thresholds are different thresholds depending...
In order to obtain a better human-machine engineering implementation effect and get a faster feedback during the bridge designing, the paper suggested a virtual simulation and evaluation method. And by using of the software Visual C++, MultiGen and Vega, an evaluation simulation system was also built. Such a system can display the whole layout of the bridge, evaluate the key human-machine designing...
In order to control the key point of accidents during bridge construction, a number of major risk factors are recognized from the point of the insecure elements of human beings and the insecure status of objects, and a risk assessment index system of bridge construction stage is created based on these risk factors; so given the uncertainty and fuzziness of the risk factors, the risk assessment of...
With the development of market economy, staff performance appraisal has been an important part of human resource management. However, due to the influence of old economic system, staff performance appraisal is susceptible to external factors and lack of effectiveness and orientation. Through analysis of the power enterprise, this paper proposes a quantitative and hierarchical assessment index system...
