Choosing the most appropriate aircraft type for a given route is one of crucial issues that decision makers at airline companies have to address under uncertainty based on various commercial, marketing and operational criteria. A novel multi-criteria making approach integrating Entropy-based Weighted Aggregated Sum Product Assessment (WASPAS) method interval type-2 hesitant fuzzy sets (IT2HFS) ...

it is firstly proved that the multi-input-single-output (miso) fuzzy systems based on interval-valued $r$- and $s$-implications can approximate any continuous function defined on a compact set to arbitrary accuracy.  a formula to compute the lower upper bounds on the number  of interval-valued fuzzy sets needed to achieve a pre-specified approximation  accuracy for an arbitrary multivariate con...

Controller design remains an elusive and challenging problem foruncertain nonlinear dynamics. Interval type-2 fuzzy logic systems (IT2FLS) incomparison with type-1 fuzzy logic systems claim to effectively handle systemuncertainties especially in the presence of disturbances and noises, but lack aformal mechanism to guarantee performance. In contrast, adaptive sliding modecontrol (ASMC) provides...

Sign language recognition has spawned more and more interest in human–computer interaction society. The major challenge that SLR recognition faces now is developing methods that will scale well with increasing vocabulary size with a limited set of training data for the signer independent application. The automatic SLR based on hidden Markov models (HMMs) is very sensitive to gesture's shape inf...

In the traditional nonlinear optimization theory, Karush-Kuhn-Tucker (KKT) optimality conditions for constrained problems with inequality constraints play an essential role. The situation becomes challenging when theory of is discussed under uncertainty. Several researchers have interval approach to tackle uncertainty and derived conditions. However, there are several realistic situations in wh...

data envelopment analysis (dea) is a method for measuring the relative efficiencies of a set of decision-making units (dmus) that use multiple inputs to produce multiple outputs. in this paper, we study the measurement of dmu performances in dea in situations where input and/or output values are given as imprecise data. by imprecise data we mean situations where we only know that the actual val...

type2 diabetic is a metabolic disease in which is associated with the relative or absolute insulin deficiency, elevated blood glucose and impaired metabolism of carbohydrates, fat and protein. since fat and exercise is important to improve glycemic control in diabetic patients, so the purpose of this study was to evaluate the effect of interval training on a cycle ergometer on insulin resistanc...

background: high intensity interval training (hiit) is a novel training method which has received most attention in recent years. the aim of this study was to examine the effect of 8 weeks of high intensity interval training (hiit) on plasma levels of adiponectin and leptin in overweight nurses. m aterials and methods: 27 nurses (mean age 25.81±60 years, height 158.01±67 cm and weight 69.41±25 ...
