Background: Communication has become one of the central themes of our contemporary societies of the Head of State to the citizens.

Objective: Everyone wonders: why so many difficulties to communicate? How to promote communication between individuals, between groups or within an organization? What to say when it comes to a crisis situation.

Methods: The interest of this work is to present the issues related to a crisis situation especially during communication.

Results:  The various episodes of communication in crises have shown that public authorities have understood issues related to the media component. The media are increasingly linked to communication.

Conclusions:  It can not be denied that communication plays a crucial role, in crisis situations, for institutions, both public and private. Communication is required to inform and reassure residents and to restore confidence. But the crisis can arise by communicating itself.

This paper studies the fluid flow congestion control model with time delay by using the switching geometric criterion method of stability for systems with time delay, discusses the stability and -stability of the model, and verifies the accuracy and validity of the conclusions by numerical simulation, finally compares the differences and connections between the two stability

The accurate prediction of on-time percentages of trains is an important issue since it can significantly affect the management of trains’ operation in many fields, such as making an appropriate timetable, organizing trains’ waiting, arranging trains’ running tracks, settling the required manpower etc. However, the problem of predicting the on-time percentages of trains is very complex and difficult since the on-time percentages of trains can be influenced by numerous factors. To deal with such a problem, genetic programming (GP) and clustering techniques are used to develop a prediction procedure by means of a mixture of experts in this study. The GP method is utilized to construct prediction models, as well as to identify the feature variables, i.e. critical independent variables. The clustering approach is applied to partition the data into several clusters where data in each cluster are as similar as possible. To illustrate the usefulness and effectiveness of this approach, prediction of the on-time percentages of local trains operated by the Taiwan Railway Administration (TRA) in Taiwan are demonstrated as a case study. The execution results show that the GP can construct an adequate model for predicting the on-time percentages of local trains. Furthermore, a comparison also shows that the technique of mixture of experts can yield a superior GP prediction model by evaluating the performance through MSE, R², and MAPE. Hence, we can consider our proposed prediction approach to be a useful and effect procedure for resolving a problem of prediction in the real world.

Earthquake is a phenomenon which causes shaking of the earth, resulting from the sudden release of an enormous amount of energy in a short time. As earthquake acts laterally on a structure, lateral load resisting systems are used. Shear walls can be defined as the vertical structural elements which resist the horizontal forces acting on a building structure. Shear walls have very large in-plane stiffness and therefore resist lateral load and control deflection very effectively. Shear walls are like vertically-oriented wide beams that carry earthquake loads downwards to the foundation. The behavior of shear walls is influenced by their proportion as well as the support condition. They are usually provided in high rise buildings to avoid total collapse of the building under seismic force. In this study, an analysis of a twenty story building, irregular in plan, in zone IV is performed by changing the location of the shear wall and the effects of the parameters like story drift and displacement are determined using standard package ETABS. Four different models have been considered and analysis is performed using time history analysis method, by considering different earthquakes.

The Banking Industry is truly the backbone of any developing country.  Technological advancement and major impacts to serve the customers in the utmost manner have influenced the banking activity majorly in the past decade. The banking industry basically depends on the adoption patterns of the customers which implies that the technological developments in the banking industry are based on the foundation of customers behavior and attitude to accept to the changes. The research paper here tries to explore the literature and studies conducted by experts in the past decade about adoption of mobile banking and the technicalities lying within. It has also put up the various regulations confronted by RBI in context of mobile banking.
