This paper describes CONFIG, an implemented hybrid modeling and simulation approach, within a discrete event system framework, and its application to control software validation. CONFIG system models are made up of connected evices and activities, and device models are made up of mode transition models, with behavior models for each mode. Behavior models can be discrete or continuous, and chara...

With the continuous development of Internet, traditional college English teaching mode no longer meets learning needs students. Therefore, how to realize innovation and improve students' ability by means information technology has become an urgent problem be solved current education departments. This paper will start with definition characteristics flipped classroom mode, combined application p...

In this paper, a preemptive multi-objective multi-mode project scheduling model for resource investment problem is proposed. The first objective function is to minimize the completion time of project (makespan);the second objective function is to minimize the cost of using renewable resources. Non-renewable resources are also considered as parameters in this model. The preemption of activities ...

Understanding mechanisms underlie the individual’s daily time allocations is very important to understand the variability of individual’s time-space constraints and to forecast his/her daily activity participation. At most of previous studies, activity time allocation was viewed as allocating a continuous quantity (daily time budget) into multiple discrete alternatives (i.e. various activities ...

every year, many accidents leading to physical injuries in kindergartens, indicates that a very large percentage of them are related to the safety concerns and lack of hygiene in these places. families, due to their busy life style and working hours and also children needs of preschool education, are searching to find most suitable kindergartens for their children. selecting a kindergarten with...

one of the most important challenges in nonlinear, multi-input multi-output (mimo) and time variant systems (e.g., robot manipulator) is designing a controller with acceptable performance. this paper focused on design a new artificial non linear controller with on line tunable gain applied in the robot manipulator. the sliding mode fuzzy controller (smfc) was designed as 7 rules mamdani’s infer...

Alzheimer's disease (AD) is the leading cause of dementia worldwide. Late-onset AD (LOAD), is the most common form of Alzheimer's disease, representing about >95% of cases and early-onset AD represents <5% of cases. Several risk factors have been discovered that are associated with AD, with advancing age being the most prominent. Other environmental risk factors include diabetes mellitus, level...

Wrist actigraphy is a simple but powerful technique that allows long term monitoring of human activity. Among the wide range of areas of application, it has a special relevance in sleep studies, where its non-invasive nature makes it a valuable tool in the detection of abnormal behavioral patterns, associated with certain sleep disorders. While the detection of simple trends, such as circadian ...

PURPOSE Use of accelerometers to assess physical activity (PA) is widespread in public health research, but their utility is often limited by the accuracy of data-processing techniques. We hypothesized that more sophisticated approaches to data processing could distinguish between activity types based on accelerometer data, providing a more accurate picture of PA. METHODS Using data from MTI ...
