In this paper, coupling properties of regular and chaotic calcium oscillations are examined. Synchronized calcium signals among coupled cells in tissue, where calcium ions were found to be one of the most important second messengers, have proven indispensable for proper and reliable functioning of living organisms. When modeling such systems, it is of particular interest to determine, which int...

This paper addresses the automatic classification of the semantic relations expressed by the English genitives. A learning model is introduced based on the statistical analysis of the distribution of genitives’ semantic relations on a large corpus. The semantic and contextual features of the genitive’s noun phrase constituents play a key role in the identification of the semantic relation. The ...

The use of paraphrases as a potential way to improve question answering, machine translation or automatic text summarization systems has long attracted the interest of researchers in natural language processing. However, manually entering reformulations into a system is a tedious and time-consuming process, if not an endless one. In this paper, we introduce a learning machinery aimed at acquiri...

Cyber-physical systems (CPS) tightly integrate cyber and physical components and transcend discrete and continuous domains. It is greatly desired that the synergy between cyber and physical components of CPS is explored even before the complete system is put together. Virtualization has potential to play a significant role in exploring such synergy. In this paper, we propose a CPS virtualizatio...

This paper describes mocas (Model Of Components for Adaptive Systems), a component model which relies on a model execution environment to create software components with self-* cabilities. A mocas component has its structure constrained by a uml profile and its behavior specified with a uml state machine. The state machine is embedded into the component at runtime and executed by an engine. The...

A new algorithm for a component placement machine is proposed in this study. The new algorithm is compared with former approaches on synthetically generated benchmark instances. It outperforms the former approaches by 3.28% on printed circuit board with 100 components to be placed. We prove that this new approach works better in a typical PCB mounted in the industry, so can be applicable to the...

Prosthetic assemblies for lower limb amputees are highly engineered and consist of several components each with its own failure mechanism. This paper describes the dynamic testing of HDPE rotational moulded sockets in a specially designed machine which mimics normal gait. Thus the components are subjected to all main loadings occurring during a stride such as axial loading and A-P bending about...

Electron cryomicroscopy (cryoEM) is capable of imaging large macromolecular machines composed of multiple components. However, it is currently only possible to achieve moderate resolution at which it may be possible to computationally extract the individual components in the machine. In this work, we present application details of an automated method for detecting and segmenting the components ...

In this paper, it is described that acoustic intensity of a rail load machine was measured for decreasing the operating noise. To locate exactly the noise sources on the machine, Operational modal measurement and analysis was performed. Comparing the results of analysis the both sets of data measured, the main components of emission noise were determined. Further, improving design of the machin...
