background: the research to date does not present an articulated approach to ensure nutrition and food systems education is systematically implemented within schools. this paper aimed to investigate food experts’ views of the best strategies to improve school‑leavers’ knowledge of nutrition and food systems. methods: in this qualitative study, 28 iranian food and nutrition experts from four maj...

background improving efficiency of health sector is of particular importance in all countries. to reach this end, it is paramount to measure the efficiency. on the other hand, there are many factors that affect the efficiency of health systems. this study aimed to measure the technical efficiency (te) of health systems in economic cooperation organization (eco) countries during 2004–10 and to d...

this paper presents h∞ control problem for input-delayed systems. a neutral system approach is considered to the design of pd controller for input delay systems in presence of uncertain time-invariant delay. using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. the significant specification of this neutral system is that its delayed coeff...

This paper investigates the stability analysis of fuzzy relational dynamic systems. A new approach is introduced and a set of sufficient conditions is derived which sustains the unique globally asymptotically stable equilibrium point in a first-order fuzzy relational dynamic system with sumproduct fuzzy composition. This approach is also investigated for other types of fuzzy relational composit...

In recent years, collaborative filtering (CF) methods are important and widely accepted techniques are available for recommender systems. One of these techniques is user based that produces useful recommendations based on the similarity by the ratings of likeminded users. However, these systems suffer from several inherent shortcomings such as data sparsity and cold start problems. With the dev...

This paper presents a theoretical approach to implementation of the “Multi-realization of nonlinear MIMO systems”. This method aims to find state-variable realization for a set of systems, sharing as many parameters as possible. In this paper a special nonlinear multi-realization problem, namely the multi-realization of feedback linearizable nonlinear systems is considered and an algorithm for ...

Increased safety has been advocated as one of the major benefits introduction Automated Driving Systems (ADSs). Incorporation ADSs in vehicles means that associated software critical application, thus requiring exhaustive testing. To prove are safer than human drivers, some work suggested they will need to be driven for over 11 billion miles. The number test miles is not, by itself, a meaningfu...

Recent world events and geopolitics have brought the vulnerability of critical infrastructure to cyberattacks forefront. While there has been considerable attention attacks on Information Technology (IT) systems, such as data theft ransomware, vulnerabilities dangers posed by industrial control systems (ICS) received significantly less attention. What is very different that can be made do thing...
