Computer network technologies have been growing explosively. Teaching computer networking principles can be enhanced using simulation through the use of interactive (not statistical based) simulation. The curriculum is based on the theory that through networking simulation programs, students are able to graphically implement the concepts learned in their coursework. With networking simulation tools, students can construct, tune, and analyze network performance while reinforcing their understanding of networking theory. Network simulation tools save money by offering the user a tool to enhance the design and integration of networks. There are many network simulation tools that allow users to model LANs, MANs, and WANs on the market. This paper describes our approach to develop computer network laboratory that enhances the understanding of a computer network course. Different computer network simulation tools have been considered and COMNET III has been selected as the tool of choice. Five labs have been developed. COMNET III is a network simulation tool that allows students and networking professionals to model, tune, and analyze the performance of various types of networks. It fosters what COMNET refers to as a "building-block approach" by utilizing a GUI interface that is comprised of "blocks" or objects representing many of the objects used in real networks. The user has the ability to adjust the objects' parameters using either default, constant, or algebraic values to better model the objects' functions

"PURPOSE:

To evaluate the accuracy of detecting cephalometric landmarks automatically by computer.
MATERIALS AND METHODS:

Digital image processing algorithms (edge-based and morphological) in addition to mathematical algorithms (knowledge-based) were used to develop a program for the identification of 15 lateral cephalometric landmarks on digital cephalograms.

Creation of emboli in the aortic root and changes in flow distribution between supra-aortic arteries and descending aorta can lead to stroke and perfusion related tissue damage during cardiopulmonary bypass. A thorough understanding of how the angle of cannulation affects the overall success of cardiopulmonary bypass during cannulation of the ascending aorta is needed. Previous simulation research has observed the effect of outflow cannula position by changing the location of the cannulation site to the subclavian artery and other vessels, as well as positions for innovative cannula designs. The purpose of this study is to evaluate the success of the procedure while using a straight cannula, modulating the angle of cannulation below horizontal in the frontal plane. A simplified geometry of the aorta was used. The success of the procedure was quantified by observing wall shear stress, normal stress, intra-fluid shear stress, and flow distribution. A numerical study was performed to solve the Reynolds Averaged Naiver Stokes governing equations, which were used in conjunction with a constant density fluid to simulate blood, and a realizable two-layer k-ε turbulence model.

Aim: The purpose of this article is to present the concept of the EvaCopNet system and the results of research on the applied solutions for the automatic
measurement of basic vital signs, transmission of received measurements to the calculating unit which analyses the level of threat to life and supports
the process of determining the order of medical evacuation.
Introduction: In the case of mass events, where the number of victims exceeds the emergency rescue potential of qualified assistance units, increasing
the sense of security for both the injured and the rescuers is possible through a monitoring device (marking) vital signs of the victim and sending information
on-line directly or via the UAV to the command post included in the evacuation and rescue process.
In many countries, systems of medical emergency evacuation of all people injured in an event are being created and developed. The presented system
is designed to support the process of evacuation and rescue of the injured. It includes the following technical solutions: a micromodule marking FT (FlagTag), a radio and organisation module for the Mesh network using unmanned aerial vehicles and a Q-Find victim location module, as well as a software
integrator module. The authors described the functions and direction of development of the micromodule marking the injured – FT.
Conclusions: An analysis of events in which the EvaCopNet system can be used as well as the conducted field tests confirm the validity of the systems’ functionality
and of the adopted solutions, and also demonstrate its great application potential. The developed solutions and components of the EvaCopNet system
are designed in such a way that it can be developed along with technical and technological progress as well as knowledge of mass events that may occur.
Implications for the practice: The EvaCopNet system is a unique technological solution, on the basis of which a fully functional evacuation and rescue
system can be developed with elements of monitoring of injured people during disasters or natural disasters. The use of the system in real rescue operations
will make it possible to decrease the number of the rescuers directly involved in observation of and supervision over the injured; on the other hand,
the rescue operation supervisor will be able to direct additional forces to proximate actions in the danger zone. The system is dedicated to entities of the
National Firefighting and Rescue System – State Fire Service and the Volunteer Fire Service.

New technologies in the field of tele-health using biosensor systems for non-invasive vital signs monitoring of patients, especially elderly people who need long-term care, and marginalized areas with hard to reach health care services are emerging. A study involving a self-care approach within the cardiac domain, where late detection increases the likelihood of patient disability or of premature death is proposed. In the study the application of e-health biosensors platform in medical services is experimented. The study resulted into the synthesis of vital signs from various body positions with biosensors that does not require a full coupled system. A model for the prevention of cardiovascular disease management based on noninvasive personal health monitoring systems with easy access for everybody, at any time or location is designed. A personal vital sign system such as ECG sensor which contain the functionality, allows recording anywhere and at any time a diagnostic quality ECG and analyzing it "on-board" by comparing it to a reference ECG, is modelled. The model called Mobile Health for the Elderly Persons (MOHELP) which relies on with application in estimation and control of boolean processes based on noisy and incomplete measurements is designed. This enabled a reliable recommendation from a digital artificial intelligence-based diagnosis, which can support an elderly person to take timely and correct decisions upon his (her) health status.

In order to fit human body, flexibility, or even better stretchability is requested for biomedical systems like implants or smart clothes. A stretchable electronic technology has been developed. This can provide highly stretchable interconnections fully compatible with PCB technologies. In order to prove the feasibility of complex biomedical systems like inner body implants or wearable systems, a variety of stretchable systems has been designed from sensor to power source systems.
