We investigate three stochastic problems (linear dynamics quadratic criterion, minimum-cost path, equipment replacement) with time-delayed control dynamics. We show how the concept of ??stage lookahead?? helps to reduce the number of arguments in the optimal value function of dynamic programming in order to alleviate the so-called curse of dimensionality.
Concept design, which is currently quite fashionable, has almost permeated all areas of design, furniture design included certainly. Based on the principle of humanity and ecologization, this paper was mainly from the point of delight-orientation and personality to discuss the concept design of the furniture, in order to bring people a sophisticated living space, meeting their spiritual demands.
With the rapid economic and technological development, a new consumption pattern -emotional consumption arises, which begin to replace the consumption of product attributes gradually. Consumers' demand for garment products has shifted from the focus on the physical functions of products to the direction which is more desirous of comforting the soul for pleasure of emotional experience, that is, from...
Harmonic colors are color sets which have special internal relationships that are aesthetically pleasing to the human eye. Color harmonization is to And the best sets of colors which will make the image more comfortable to human visions. An improved technique of best scheme searching for automatic color harmonization is proposed in this paper. By considering the predominant color in image and its...
The effectiveness of queue management mechanisms relies on how good their control decisions will help in satisfying their goals regarding congestion avoidance and control. These decisions are implemented and compelled during the design of the packet mark probability and the mark activation functions. The design of fast congestion notification (FN) drop/mark probability function enables the two control...
One of the tasks facing historians and conservationists is the authentication or dating of medieval manuscripts. To this end it is important to them to verify whether writings on the same or different manuscripts are concurrent. In this work we explore this task by capturing images of manuscript pages in infrared (IR) and modelling and then comparing the ink appearance of segmented text. The modelling...
In this paper, we experimented for analyzing users' behavior on remote controller logs. We recorded the DVD recorder's signal data using IrRC-logger can record infrared signal (Ir-signal) from remote controller to the appliances. We focused on interval time between error/correct signal and previous signal, and analyzed a difference between error interval time and correct interval time. The results...
Effect of consecutive maximal dry breath-holds was compared between two groups of free divers with different experience levels and a control group. Hemoglobin concentration ([Hb], by functional near infrared spectroscopy, fNIRS), heart rate and systemic oxygen saturation (SO2, by pulse oxymetry) measurements were performed during four consecutive maximal dry breath-holds change in [Hb] (Delta[Hb]),...
Fatty liver refers to the accumulation of intense fat in liver cells. It is known that liver cirrhosis could develop in %10-40 of adult patients suffering from liver inflammation due to extreme fat deposition in liver. For the diagnosis fatty liver, ultrasound images liver are visually compared to parenchyma tissue of kidney. The condition of fatty liver is classified little fatty or much fatty.....
Although, stress, sleep deprivation, excessive fatigue and inattention are common health problem in advanced society, there are many methodological problems that make it difficult to measure these emotional states in clinical situations. The main goal of this study is to investigate whether variation of stress due to treatment techniques used in a hospital setting can be successfully assessed and/or...
Different tissues energy consuming values show differences from each other. Conductivity and metabolic heat source of the tissue alter whether it is healthy or not. The temperature differences of tissues take the thermal infrared imaging into very important and vital point. It was not possible to be able to detect these amounts of differences with the early instrumentation and technology. However,...
A new device for correction of eyelid problems due to facial palsy was studied. Ineffectiveness of the upper eyelid of the paralyzed side for totally closure is called lagophthalmos which may cause drying and irritation rabbits were injected with local anesthetics to induce temporary facial palsy and Lagophthalmos. In order to provide functionality to the upper eyelids, Ferromagnetic pieces were placed...
Bone cements are used in orthopaedic surgery and dentistry, and the commonly used commercial ones are prepared from poly (methylmethacrylate) (PMMA). In orthopaedic surgery bone cements are used as filling agents for the treatment of damaged tissues and they are used to stabilize the prosthesis by providing the mechanical interlock between bone and metal during the use of metal prothesis and to provide...
Video game playing is an attractive form of entertainment among school-age children. Although this activity has many adverse effects on child development, there have been only a few studies examining the biological effects of video games on brain activity. The aims of this study were i) to investigate effects of video game playing on attentional capacity and visual skills ii) to relate training induced...
Within the framework of quality management in medical services, the calibration gains great importance through appropriacy of medical devices. The aim of this study is to investigate the effects of temperature factor to the amount of gas output from the vaporizator and to enhance the consideration of these factors while adjusting the amount of gas to be given to the patient during the operation. In...
In this study, 27 young and healthy subjects was listening to the classical and Turkish music samples which are believed to changeable the subject's emotional state. Their effects on autonomic nervous system (ANS) are investigated by using the heart rate variability (HRV) analysis which is accepted as a non-invasive indicator of ANS. The electrocardiogram (ECG) and respiration records were made before...
This is the second study exploring the creation of evolved art through evolutionary control of a dynamical system. Here 1-dimensional cellular automata rules are evolved to exhibit slow but persistent growth or to undergo planned senescence. These simple constraints encourage the automata to develop complex and visually pleasing behavior. Isotropic automata with a forced quiescent state are used,...
In this paper, a graph-based method for video content analysis is proposed. The characteristics of the detected shots are investigated for news, commercial, animated cartoon, basketball and documentary videos and experimental studies are realized on these videos. The maximum clique on the weighted and undirected graph, which is constructed according to visual content, is tried being detected. It is...
There has been increasing interest in the study of video based fire detection as video based surveillance systems become widely available for indoor and outdoor monitoring applications. Video based fire detection methods in computer vision literature do not take into account whether the fire takes place in the day time or at night. A novel method explicitly developed for video based detection of fire...
In this paper; the signals consisting of power quality disturbances is determined by using statistical methods. Five kind of power quality disturbances such as voltage swells, voltage sags, voltage with harmonics, transients and flicker which last duration of 18 periods are constituted by using MATLAB. Sampling frequency is 12.8 kHz. Skewness and kurtosis coefficients of constituted signals are calculated...
