It is a common practice amongst programmers to construct parts of software programs by imitating parts of programs constructed by more experienced professionals. This “learn by example” approach can be applied at the design level by using patterns as sets of rules and recommendations to solve well-defined tasks within the development of computer-based systems. This paper describes the multi-lev...

In many electronic applications, chemical etching process is used to manufacture the substrates. This method has been applied for long on quartz crystal blanks manufacturing for minor adjustments of the vibration frequencies. This paper pesents a way to implement an industrial chemical etching process specially dedicated for large thickness removals without damaging the blanks surface texture. ...

Rapid prototyping has become the primary means by which assembly engineers obtain prototype parts needed for systems design. Some predict that rapid prototyping will soon evolve into rapid manufacturing. Rather than having factories full of mass production equipment, factories will consist of hundreds of inexpensive layer-based fabrication machines that can economically produce custom parts. Ma...

Air conditioners are commonly used to keep electronics cool in various areas, such as industrial automation, telecommunication equipment, security and defense systems as well as other indoor and outdoor electronics applications. The electronics may be housed in protective enclosures, where air conditioners deliver cooled air to keep the entire enclosure at desired temperatures for optimum elect...

There are proposed models of contracts, technological equipment and gas networks and methods of their optimization. The flow in network undergoes restrictions of contracts and equipment to be operated. The values of sources and sinks are provided by contracts. The contract models represent (sub-) networks. The simplest contracts represent either nodes or edges. Equipment is modeled by edges. Mo...

this article identifies the factors which create and maintain the long term relationship between industrial crane suppliers and their buyers. a random sample of 79 respondents of buying companies was tested by structural equation models with lisrel and pls. findings revealed that latent variables like satisfaction, trust, commitment and intention to continue relationship had goodness of fit. th...

Numerical simulation of industrial crystal growth is difficult due to its multidisciplinary nature and complex geometry of real-life growth equipment. An attempt is made to itemize physical phenomena dominant in different methods for growth of bulk crystals from melt and from vapour phase and to review corresponding numerical approaches. Academic research and industrial applications are compare...

In the context of a global competitive environment, industrial companies have to pursue continuous performance improvement, leading to the popularity of Lean Manufacturing throughout the world. Overall equipment effectiveness (OEE) is considered the relevant performance measurement tool, which is able to take into account a machine’s availability, performance and quality. Therefore, many firms ...

This paper presents a communication framework for integrating sensors in a robotic laser welding system. The framework was originally developed for the application of sensorguided robotic laser welding, but the principles are generic, making it useful in other application areas as well. To use the sensor measurements during the robot motion, a synchronisation mechanism is presented for an image...
