The wavelengths selection of Fourier transform infrared (FTIR) spectroscopy with attenuated total reflection (ATR) techniques was very important for improving model prediction effect, and reducing model complexity. Based on the difference of mean spectrum, a wavelengths combination selection method of FTIR/ATR analysis of total cholesterol in human serum was developed. 10 wavelengths with peaks were...
IT services are getting increasingly complicated, and require IT support organization to manage them. IT support organization are in charge of the incident management process and represent mission-critical structures whose performance needs to be frequently assessed and optimized. State-of-the-art research in the performance optimization of IT support organization proposes user-driven performance...
One of the great benefits VR systems offer is their ability to simulate a number of virtual humans when their presence is needed in the context of some learning or training experience. Being that the real humans may not be available to play different roles and support virtual sessions, the ability of a system to generate highly believable representations of autonomous virtual humans — virtual intelligent...
Low adoption rate of Electronic Medical Record (EMR) systems is hindering achieving a national health care cost reduction estimated at $12 billion over the next 10 years. Physicians' EMR adoption rates are as a low as 10% nation-wide, due in part to poor design of the system user interface. The poor design is impacting EMR usability where physicians are faced with information overload. This is causing...
This paper contributes to the efficiency oriented assessment of system architecture. It proposes to use function modeling to support system analysis aiming at the development of efficiency oriented assessment approaches for complex system architectures. Efficiency orientation implicates the processes executed by the systems as focused assessment dimension. The two-level function modeling approach...
Aerial lifts are machines that enable human workers to comfortably work at heights that might otherwise be inaccessible. They typically have multiple long-reach arms to enable working at such heights. There is typically enough flexibility in these arms to result in deflections of the lift endpoint, the bucket where the operators are located. These deflections can be excited by either motion of the...
This paper proposes a novel nonlinear manifold learning method for addressing the ill-posed problem of occluded human action analysis. As we know, a person can perform a broad variety of movements. To capture the multiplicity of a human action, this paper creates a low-dimensional manifold for capturing the intra-path and inter-path contexts of an event. Then, an action path matching scheme can be...
In an attempt to increase performance and competitiveness, Small and Medium Enterprises (SMEs) requires individual and organizational knowledge. In order to disseminate individual knowledge in the organization, it is needed knowledge transfer in SMEs which facilitated by the knowledge conversion. Knowledge that will be converted in SMEs is the knowledge about the products, manufacture of products,...
A decrease in extracellular calcium concentration ([Ca2+]o) prolongs the action potential (AP) in ventricular cardiomyocytes, and vice versa. Although this phenomenon can be relevant to arrhythmogenesis in clinical settings, it is not included in most of the commonly used computational models of ventricular AP. Therefore, the aim of this study has been to improve a recently published human ventricular...
Taking advantage of neural network back propagation algorithm and Takagi-Sugeno fuzzy inference system, a kind of pilot model is developed based on adaptive neural fuzzy inference system. A longitudinal man machine systems in air-refueling condition is simulated. The simulation results show that the model presented by our scheme is reasonable and can be used to illustrate the handling behavior of...
FATS serves as a Energy store and FDA recommends about 30% calories of human diet can be from fats. Edible oil is a major source of FAT, where the quality of the oil cannot be compromised. As the demand increases, adulteration of edible oil with cheaper oil is also prevalent. Simple chemical methods can be used to detect adulteration but they are not accurate. So to determine, authenticate the micro...
Concussion or head impact involves the brain injury from mild to severe. Most of the brain injury mechanism and brain lesions can be investigated from medical imaging. Alternatively, finite element model (FE model) of head impact is used for simulation and analyzing the brain concussion. Although a number of head impact models have been designed, they are still not be realistic. This paper proposes...
Societal information systems are intended to assist the members of a society in dealing with the complexities of their interactions with each other, especially regarding the resources they share. Because the members are distributed and autonomous, we believe that software agents, having these same characteristics, are a natural basis for representing the members and their interests in a societal information...
We aim to develop a shopping companion robot that can share experience with users. In this study, we focused on the shared memory acquired when a robot walks together with a user. We developed a computational model of memory recall of visited locations in a shopping mall. The model was developed with data collection from 30 participants. We found that shop size, color intensity of facade, relative...
We first define and explain the notions of rapid prototyping and societal information systems. Thereafter we introduce a design method appropriate for designing and rapid prototyping of societal information systems — agent-oriented modeling. Following, we describe a “proof-of-concept” case study of applying agent-oriented modeling to rapid prototyping of a societal information system for finding an...
The paper proposes a new mobility model able to properly reproduce the spatial, temporal and social features that can be observed in real mobility datasets. The model, named Geo-CoMM, is based on the quantities that guide human mobility and their probability distributions by directly extracting their setting from the statistical analysis of GPS-based traces. In Geo-CoMM, people move within a set of...
It is becoming common practice to migrate signal-based video workflows to IT-based Video workflows. Video workflows have some inherent features, including: 1) necessary human involvements in video workflows introduce security and authorization concerns; 2) the frequent change of video workflow contexts requires a flexible approach to acquiring performance data; 3) the content-centric nature of video...
One of the popular dynamics on complex networks is the epidemic spreading. An epidemic model describes how infections spread throughout a network. Among the compartmental models used to describe epidemics, the Susceptible-Infected-Susceptible (SIS) model has been widely used. In the SIS model, each node can be susceptible, become infected with a given infection rate, and become again susceptible with...
Due to the complex and relatively unpredictable nature of human behavior, customer service-based processes such as those featured in call centers, restaurants, and hotels can be challenging to model. The present study provides an example of using established theories of customer behavior, in combination with primary data collection, in a time and cost efficient way to model customer decision-making...
In this paper, we investigate the parochialism in dynamic spectrum access networks and its effect on spectrum resource competition and self-coexistence among cognitive radio secondary users. We assume that some greedy secondary users in the network form a parochial community in private and try to maximize their own utilities without concern for the interests of other secondary users outside the community...
