background: adolescence is a sensitive period of acquiring normal and abnormal habits for all of life. the study investigates determinants of responsibility for health, spiritual health and interpersonal relations and predictive factors based on the theory of planned behavior in high school girl students in tabriz.   methods : in this cross-sectional study, 340 students were selected thorough m...

The Clopper-Pearson confidence interval has ever been documented as an exact approach in some statistics literature. More recently, such approach of interval estimation has been introduced to probabilistic control theory and has been referred as non-conservative in control community. In this note, we clarify the fact that the so-called exact approach is actually conservative. In particular, we ...

in this paper, a multi-product continues review inventory control problem within batch arrival queuing approach (mqr/m/1) is modeled to find the optimal quantities of maximum inventory. the objective function is to minimize summation of ordering, holding and shortage costs under warehouse space, service level, and expected lost-sales shortage cost constraints from retailer and warehouse viewpoi...

quality control plays an important role in increasing the product quality. fuzzy control charts are more sensitive than shewhart control chart. hence, the correct use of fuzzy control chart leads to producing better-quality products. this area is complex because it involves a large scope of industries, and information is not well organized. in this research, we provide a literature review of th...

We plunge decentralized control problems into modular ones to benefit from the know-how of modular control theory: any decentralized control problem is associated to a natural modular control problem, which over-approximates it. Then, we discuss how a solution of the latter problem delivers a solution of the former.

The objective of the present research is to make use of optimal control theory to solve a serious environment and transportation problem.

Perceptual Control Theory (PCT) is a systems model for the regulation of actions based on negative feedback loops as used in engineering control theory (Powers, 1973; Robertson, & Powers, 1998). An everyday example of an engineering control system is the cruise control in your car. By way of illustration, the speed limit is 70 mph, so you set the cruise control at 70 mph. The cruise control now...

References 197 Preface Striking developments have taken place since 1980 in feedback control theory. The subject has become both more rigorous and more applicable. The rigor is not for its own sake, but rather that even in an engineering discipline rigor can lead to clarity and to methodical solutions to problems. The applicability is a consequence both of new problem formulations and new mathe...

Control theory is the discipline that concerns itself with the response of dynamical systems to input. Control theory is a eld that spans both mathematics and engineering as it nds the vast majority of its applications while providing many complex problems as the topic of much mathematical research. Such problems often deal with questions such as stability, robustness (tolerance in variation of...
