Heat transfer in counterflow heat exchangers is modeled by using transport and balance equations with the temperatures of cold fluid, hot fluid, and metal pipe as state variables distributed along the entire pipe length. Using such models, boundary value problems can be solved to estimate the temperatures over all the length by means of...

Purpose: The COVID-19 pandemic is a new crisis in the world that caused many restrictions, from personal life to social and business. In this situation, the most vulnerable groups such as refugees who are living in the camps are faced with more serious problems. Therefore, a system dynamic approach has been developed to evaluate the effect of...

The paper describes how a multidisciplinary team has developed, on behalf of Ansaldo Energia Spa, a methodology based on the technologies made available by Industry 4.0; a methodology that allows rescue teams to quickly intervene in the event of man-down in isolated areas of the plant where the unfortunate person would risk being found with...

The Authors of this paper had first conceptualized and then developed the automated picking plant described in the paper "A 4.0 Automated Warehouse Storage and Picking System for Order Fulfillment", presented by the Authors to the WCE 2021 IAENG Congress and awarded with the "Best Paper Award of the 2021 International Conference of...

In this paper the authors address the problem of surveillance of bedridden patients in hospitals and residences for elderly. Unfortunately, patients cannot be supervised by operators 24 h a day, given the associated costs. An attempt to solve this problem is already provided by wearable devices. This paper describes a 4.0 system implemented to...

Thanks to the principles and technologies made available by Industry 4.0, the authors conceptualized and modeled a new strategy, capable of making an effective contribution to the problem of limiting contagion from Covid19 today, and tomorrow from any possible other type virus, bacteria or pathogen agent introduced by subjects who, although...

The Paper deals with the management of the operating block in its many activities. By a new approach and with innovative machinery specific several problems were thus studied and overcome, such as the control of hospital infections, the operations of washing and sterilization of surgical instruments, the planning of interventions, the tracking...

Ansaldo Energia is a Major Player in Italy for metal mechanic production which decided to adopt Industry 4.0 standards. One of the main projects, at this purpose, was to develop a new vision concerning Safety. The goal was achieved by a Team built specifically by the Company. Particular importance was assigned by the Team to PPE (Personal...

In the repeated interventions carried out by the authors in the healthcare sector [1–4] (hospitals, outpatient clinics and clinics), including assistance facilities (residences for the elderly and outpatient medical offices) the problem of so-called hospital or nosocomial infections has always been reported to the team by the medical and...

A major player in metal mechanic manufacture in Italy that has opted to implement Industry 4.0 standards. One of the key projects undertaken was the creation of a new vision for safety. The aim was met by a team created expressly for the company. The Team placed a high value on PPE (Personal Protective Equipment), which is equipment meant to...

Healthcare and more precisely private hospitals are critical and complex environments where making appropriate decisions is vital. For this reason, they are widely studied in many fields. This paper aims to provide the current state of the art of Digital Twin and/or Simulation involved in Decision Support System (DSS) whose data are processed...

This paper deals with outlining the main causes of floods. We analyze statistical data on the number of largest floods and the number of people in Russia affected by this phenomenon. We also classify floods by their causes and reveal the defining relationship between the number of floods and the number of spring high waters caused by melting...

A fundamental aspect of the fight against the Coronavirus and against any other virus, is represented by the sanitization of the sites and objects contained therein. This operation is normally carried out using mixtures of ozone and steam and it is certainly effective but also limited due the damages that the vapor can cause to rooms and...
