this lecture introduces testing methods for the protection of children in vehicles. in order to reduce the fatalities and injuries of children in transportation state of the art child protection is mandatory. global laws and regulations such as ece or fmvss are introduced and compared with new car assessment programs (ncap). engineering tools and equipment to test according to global child prot...

The paper focuses on the impact grid-connected, largescale photovoltaic (PV) has on the power system operation (stability, availability, reliability) and protection philosophy. It assesses qualification methods and standards of particularly the utility-interactive equipment (grid inverters), which directly influences the security of supply and power quality of the grid. Advanced emulation of gr...

A dynamic compression testing system, consisting essentially of a pendulum, abutment, and electronic recording equipment, was built by the Laboratory for testing package cushioning materials. The tests simulate the loading of an item in a cushioned package when the package is impacted. The characteristics, limitations, and theoretical aspects of each component of the instrumentation are present...

In this paper, we made the plan of a load testing, and got results by means of the LoadRunner which is an automatic load testing tool. We combined with the characteristics of electronic commerce system and did the load testing and analysis the result of load test by means of the LoadRunner. We fully described the characteristics of the electronic commerce application, designed the reasonable te...

A test suite for a key interface within a dimensional measuring system (coordinate measuring machine or CMM) is presented. The test suite consists of test procedures, test definitions, and various testing utilities. A real-time, distributed test utilizing the test suite has been performed and is described. Keywords— conformance test, coordinate measuring machine, distributed testing, interface ...

Modern telecommunication equipment differs quite significantly from equipment used in the past. While in traditional networks the behaviour of each transmission channel was deterministic, modern transmission systems may behave nonlinear and time variant even during a call. Signal processing is used extensively, mostly at the end points of a connection. The impairments introduced by the transmis...
