Recently there has been an increasing interest in primal-dual methods for model predictive control (MPC), which require minimizing the (augmented) Lagrangian at each iteration. We propose a novel first order method, termed proportional-integral projected gradient MPC where underlying finite horizon optimal problem both state and input constraints. Instead of Lagrangian, iteration our method onl...

Performance assessment and monitoring of control systems can be used to improve the performance of industrial processes. In this paper, a novel relay feedback based method for monitoring and automatic retuning of a class of proportional-integral (PI) controllers is proposed for the systems with gain nonlinearity. For performance assessment of the closed loop system, a time domain evaluation cri...

There is an increasing pressure by the community and customers forcing companies to insert environmental concerns in their practices. To help initiatives, green bonds market was created. Our research question “How select a growing billion-dollar market?” This paper presents multi-criteria decision analysis (MCDA) model enable investors identify opportunities based not only opinions, but grounde...

Introduction Breast cancer is the second cause of mortality among women. Early detection of it can enhance the chance of survival. Screening systems such as mammography cannot perfectly differentiate between patients and healthy individuals. Computer-aided diagnosis can help physicians make a more accurate diagnosis. Materials and Methods Regarding the importance of separating normal and abnorm...

Hierarchical Multi-Label Classification is a complex classification task where the classes involved in the problem are hierarchically structured and each example may simultaneously belong to more than one class in each hierarchical level. In this paper, we extend our previous works, where we investigated a new local-based classification method that incrementally trains a multilayer perceptron f...

heavy metal concentration in the soils and sediments has increased worldwide during the last century due to the mining, smelting, and industrial activities. the forumad chromite deposit is located in the sabzevar ophiolitic complex (soc), with a long history of mining activities, yet very little is known about the heavy metal contamination in its surrounding environment. in this research work, ...

alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(iii) complex (1) and tris-(2-formylphenolate) aluminum(iii) complex (2) at 600, and 1000 °c for 3h. the obtained data showed that the procedure without using fuel resulted in a better phase and morphology. to investigate the phase formation, powder x-ray diffraction technique was use...

Due to significant progress in cancer treatments and management in survival studies involving time to relapse (or death), we often need survival models with cured fraction to account for the subjects enjoying prolonged survival. Our article presents a new proportional odds survival models with a cured fraction using a special hierarchical structure of the latent factors activating cure. This ne...

Many networks in nature, society and technology are characterized by a mesoscopic level of organization, with groups of nodes forming tightly connected units, called communities or modules, that are only weakly linked to each other. Uncovering this community structure is one of the most important problems in the field of complex networks. Networks often show a hierarchical organization, with co...
