A critical infrastructure is a complicated system whose failure (in whole or in part) has significant impact on national interests, including security, the economy and basic human needs. The consists of relevant sectors, elements their mutual linkages. In order to study infrastructures, it necessary apply systems approach based cross-sectoral evaluation research into linkages between individual sectors. Specifically, describe vertical horizontal levels each associated From this...
Temperature affects the number of water properties. Density, specific heat capacity, surface tension and more change with temperature. The size droplets has strong impact on shielding radiant or ability to extinguish suppress fires. Determining droplet distribution mist is used in wide range industries, fire protections, spray technology, pharmaceuticals automotive industry. work deals measurement eight selected nozzles at different temperatures using laser diffraction method. are designed...
The paper deals with the measurement and identification of surfaces after machining in a non-contact manner. It presents new modified method its implementation, results intensity distribution defocusing plane, their analysis interpretation. scanned at plane gives information necessary to assess second derivatives, thus, surface functions which can be used determine groove curvatures real morphology. proposed has proved very sensitive evaluating differences between finishing methods by...
This article focuses on the interaction of thermal radiation with water droplets and creation mist for purpose evaluating decrease heat flux when positioning a curtain various parameters between source radiometer. The change parameters, affecting passing through radiation, was performed using five nozzles variable spray characteristics. For respective attenuation determined transmittance calculated. Water created high‐pressure pump different size orifice. measurement droplet time‐shift...
The main aim of this article is to design a monitoring center for collecting and evaluating the physiological function retired patients in nursing homes. system should be able collect information body heat, heart rate, blood oxygen, orientation, sleep time form little bracelet. part with program can placed into personal computer (PC) which provide user-friendly interface easy managing. display all needed patient from previous days or months graphs person have view patient´s health....
Surface plasmon resonance imaging biosensors have a number of advantages that make them superior to other analytical methods. These include the possibility label-free detection, speed and high sensitivity low protein concentrations. The aim this study was create analyze biochips, with help which it is possible test cystatin C in patient urine samples compare results one-time traditional ELISA method. main advantage surface method repeated measurements over long period time accordance...
<p>On the basis of an analysis terrorist attacks carried out worldwide, where in recent years a preference for use bulk explosives placed vehicles prevails, effective protection against these malicious explosive-containing systems that have single goal - to cause death and significant material damage large radius is dealt. These improvised explosive devices are, pyrotechnical terms, ranked as one most weapons, with highly destructive character effect. A special water shaped charge able...
Steel wire ropes are among the essential technical elements widely used in many industries. The impeccable condition of these has a major impact on safety entire facilities where they applied, be it construction, mining, agriculture, transport, engineering or another area. This article focuses comparing two non-destructive methods designed to study internal defects steel ropes. They defectoscopes with different principles operation, namely MID-3 magnetic defectoscope both excitation and...
Water mist systems are increasingly used in a wide range of applications. These play an important role fire suppression, firefighting, and generally combating the effects fire. has ability to reduce ambient, flame fuel temperatures. It is also capable wetting preventing spread flames unburned fuel. displace oxygen combustible gases from area, radiant heat, or trap toxic other particles smoke. The effectiveness water depends on its parameters. This article focuses most ones, namely spray...
Determining the particle size distribution of water mist is necessary for a wide range industrial applications or experimental measurements. Particle defines ability to absorb heat, scatter heat radiation, inertize environment, reduce environmental dust, regulate odor, etc. The paper presents principle measuring droplet using laser diffraction and measurement procedure four hollow cone nozzles with orifice 400 µm, 500 600 µm 1000 µm. measurements were performed at distances 25 mm, 50 75 100...
Abstract This article documents the development of noninvasive use explosives during destruction ice mass in river flows. The system special sequentially-timed charges utilizes increase efficiency cutting by covering them with bags filled water, while simultaneously increasing effect entire timed charges. Timing, spatial combinations placement, and linking these results loosening barriers on a frozen waterway, at same time regulating size fragments. developed will operability safety IRS units.
Abstract The premises of international airports in CR are major air transport hubs as well key elements critical infrastructure, belonging to the very high risk category. Any infringement leading limitation or complete shutdown would cause considerable economic and psychological damage. most important task is ensure quality reliable physical technical protection airport, because especially summer months these areas collect large numbers people a possible terrorist attack could be fatal. This...
