The aim of this paper is to describe the process of the design and implementation of IP Multimedia Subsystem (IMS) in one Telecom Operator in Bosnia and Herzegovina. IMS gives Telecom Operators the opportunity to do the convergence of fixed and mobile communication networks into one single network. In this work, the design and implementation of IMS system has been done by using ITIL V3 recommen...

In this paper we share our experiences on establishing, running, and extending a Next Generation Network (NGN) and IP Multimedia Subsystem (IMS) testbed. The testbed has been designed based on the layered architecture of NGNs and aims at satisfying Information and Communication Technology (ICT) industry requirements for open and flexible testing infrastructures. In the center of this telecommun...

Abstract Gas chromatography-ion mobility spectrometry (GC-IMS) is an emerging analytical technique that has the advantages of fast response, high sensitivity, simple operation, and low cost. The combination speed resolution GC with sensitivity IMS makes GC-IMS play important role in detection food volatile substances. This paper focuses on basic principles future development trend, comparative ...

Background: Analysis of exhaled breath, especially of volatile organic compounds (VOCs), is of increasing interest in the diagnosis of lung cancer. Compared to other methods of breath analysis, ion mobility spectrometry (IMS) offers a ten-fold higher detection rate of VOCs. By coupling the ion mobility spectrometer with a multi-capillary column as a pre-separation unit, IMS offers the advantage...

The IP Multimedia Subsystem (IMS) was developed by a common initiative of the standardization bodies 3GPP and ETSI TISPAN with the aim to provide a platform for fixed and mobile network operators that supports future communication services. In this article we give an overview about the implications that security threats already known from the Internet have on IMS. We analyze the security requir...

The use of efficient signal processing tools (SPTs) to extract proper indices for the fault detection in induction motors (IMs) is the essential part of any fault recognition procedure. The 2nd part of this two-part paper is, in turn, divided into two parts. Part two covers the signal processing techniques which can be applied to non-stationary conditions. In this paper, all utilized SPTs for n...
