Mid-infrared (mid-IR) supercontinuum (SC) sources have recently gained much interest, as a key technology for such applications as spectral molecular fingerprinting, laser surgery, and infrared counter measures. However, one of the challenges facing this technology is how to obtain high power and broadband light covering a spectral band of at least 2-5 μm, especially with a very efficient output power distribution towards the mid-IR region. This directly affects their usage in the practical applications mentioned above. Typically, an SC is generated by pumping a piece of nonlinear fibre with high-intensity femtosecond pulses provided by mode-locked lasers. Although this approach can lead to wide continuum generation, the output power is limited only to the milliWatt level. Therefore, to achieve high-power SC light, other laser systems need to be employed as pump sources. This paper briefly reviews SC sources, restricted to those with an average output power of over 0.4 W and simultaneously with a long-wavelength edge of the continuum spectrum of over 2.4 μm. Firstly, the concepts of SC generation, including the nonlinear phenomena governing this process and the most relevant mid-IR fibre materials, are presented. Following this study, a review of the main results on SC generation in silica and soft-glass fibres, also including my experimental results, is presented. Emphasis is given to high-power SC generation with the use of different pump schemes, providing an efficient power distribution towards longer wavelengths. Some discussion and prospective predictions are proposed at the end of the paper. © 2014 Elsevier Ltd. All rights reserved.

Development of focal plane arrays started in seventies last century and has revolutionized imaging systems in the next decades. This paper presents progress in optical detector technology of focal plane arrays during the past twenty years. At the beginning of paper, emphasises are given on integrated detector assembly and cooling requirements of different types of detectors. Next, the classification of two types of detectors (photon detectors and thermal detectors) is done on the basis of their principle of operation. This topic is followed by general overview of focal plane array architectures. The main subject of paper is concentrated on describing of material systems and detectors operated in different spectral ranges. Special attention is given on recent progress in their detector technologies. Discussion is focused mainly on current and the most rapidly developing focal plane arrays including: CdZnTe detectors, AlGaN photodiodes, visible CCD and CMOS imaging systems, HgCdTe heterostructure photodiodes, quantum well AlGaAs/GaAs photoresistors, and thermal detectors. Emphasis is also given on far-infrared and sub-millimetre wave detector arrays. Finally, the outlook for near-future trends in optical detector technologies is presented. © 2012 Elsevier Ltd.

In the paper, fundamental and technological issues associated with the development and exploitation of the most advanced infrared detector technologies are discussed. In this class of detectors both photon and thermal detectors are considered. Special attention is directed to HgCdTe ternary alloys on silicon, type-II superlattices, uncooled thermal bolometers, and novel uncooled micromechanical cantilever detectors. Despite serious competition from alternative technologies and slower progress than expected, HgCdTe is unlikely to be seriously challenged for high-performance applications, applications requiring multispectral capability and fast response. However, the nonuniformity is a serious problem in the case of LWIR and VLWIR HgCdTe detectors. In this context, it is predicted that type-II superlattice system seems to be an alternative to HgCdTe in long wavelength spectral region. In well established uncooled imaging, microbolometer arrays are clearly the most used technology. Present state-of-the-art microbolometers are based on polycrystalline or amorphous materials, typically vanadium oxide (VOx) or amorphous silicon (α-Si), with only modest temperature sensitivity and noise properties. Basic efforts today are mainly focused on pixel reduction and performance enhancement. Attractive alternatives consist of low-resistance α-SiGe monocrystalline SiGe quantum wells or quantum dots. In spite of successful commercialization of uncooled microbolometers, the infrared community is still searching for a platform for thermal imagers that combine affordability, convenience of operation, and excellent performance. Recent advances in MEMS systems have lead to the development of uncooled IR detectors operating as micromechanical thermal detectors. Between them the most important are biomaterial microcantilevers. © 2010 Elsevier Ltd. All rights reserved.

Experimental studies on ductility of selected metals differing mechanical properties under strain rates between 4 × 10 3 and 2 × 10 4 s -1 are presented in this work. The electromagnetic expanding ring experiment was used as the primary tool for examining the ductility behaviour of metals. Through a use of the Phantom v12 digital high-speed camera and specialised TEMA Automotive software, rings expansion velocities were determined with satisfactory accuracy for all ring tests. In this paper, the experimental observations on cold-rolled copper Cu-ETP, aluminium alloy Al 7075, barrel steel and tungsten heavy alloy are reported. Ductility of studied materials was estimated by measuring changes in cross-sectional areas in the uniform strain portions of the recovered ring fragments. In a similar way the metals ductility was defined at the conventional tensile test condition. Moreover, results of analogue investigation for static and dynamic loading at the temperature of about -40 °C were described. The experimental observations mainly revealed the different ductility behaviour of metals tested at applied dynamic loadings; Cu-ETP and barrel steel demonstrated an increase in ductility, whereas aluminium alloy Al 7075 and tungsten heavy alloy were characterised by lower ductility in comparison to static loading. These results appear to be partially in contrast with the observations reported recently by some other investigators. © 2012 Elsevier Ltd. All rights reserved.

A method of combined extraction of gaseous hydrocarbons and CO_(2) storage in horizontal wells which involves drilling a vertical well (1) in the gas-bearing shale deposit (2) located between seams of different types of rock (3), where horizontal or quasi-horizontal wells (4a, 4b, 4c) are drilled off radially at least at two depths, and then the horizontal wells (4b, 4c) are closed with plugs and/or valves controlled from the surface (6b, 6c), into which flexible or semi-flexible small-diameter pipes (7) are brought in via the main vertical (1). The pipes (7) are brought into the lateral wells (4a), and then they are used for injecting cooled, compressed liquid CO_(2), possibly with an admixture of dry sand to maintain fractures, into the gas-bearing shale deposit (2) using a cryogenic pump, while the temperature and pressure in the wells (1) and (4a) are controlled during the CO_(2) injection on an ongoing basis by appropriate sensors installed inside them. After this stage is completed, the wells (4a) are also closed with plugs and/or mini-valves controlled from the surface in the vertical pipe, and in the shale deposit (2), the process of CO_(2) decompression begins and it undergoes phase transition under the temperature in the deposit, which causes intense shale fracturing, CO_(2) adsorption and simultaneous shale gas desorption. Then the lateral wells (4a) are pre-perforated and pressure sensors are installed near the closed lateral wells to enable controlling shale processes. The resulting fractures (5) in the gas-bearing shale deposit (2) enable releasing shale gas which is forced out by heavier CO_(2). The lateral wells (4b, 4c) are opened and the released gas under high pressure comes out via the vertical well (1), and the process of gas recovery from the well can occur spontaneously or be carried out under reduced pressure. The method may also be used for storing CO_(2) greenhouse gas after exhaustion of the shale gas deposit in that the gas deposit is shut in permanently by plugging the well at an appropriate height or closing it with a possibility of further use of the deposit.

Pipeline systems have supreme significance for an effective functioning of industry providing Eastern and Western European markets with energy resources: crude oil, natural gas and liquid petroleum products. Taking into account long life of pipeline networks and situation, when over 20% of large-diameter pipelines are with an exhausted lifetime, an important task at the present time becomes an ensuring of reliability for these transport systems. An intensive study shows that among the main reasons of pipeline accidents are the volumetric surface defects (VSD) arising as a result of corrosion or erosion-corrosion processes and by this way considerably decreasing the pipeline strength. In order to ensure efficient and safe operation of existing pipelines, operating companies routinely inspect the pipes. The methods that are used for this purpose, like smart pig, are sufficiently expensive, require, in some cases, significant reconstruction and have an insufficient sensitivity. An application of new composite materials for the repair of damaged pipelines considerably improved situation in the last time. However numerous standards associated with this type of repair are based on simplified approaches and do not take into account the stress-strain state in the damaged areas. Strategic objective of the project is addressed to the improvement of infrastructure in EU and Third counties by the rising of reliability of existing pipeline systems. Work over this project will serve IRSES main goal achievement strengthening research partnerships through short period staff exchanges and networking activities between organisations from EU and Third countries. The scientific and technical objectives are improvement of existing and developing of new methods for detection and repair of VSD based on low-frequency ultrasonic testing with directional waves and advanced composite repair systems to bring efficiency of damaged section up to the level of undamaged pipeline.

The goal of the PROTECT project is an enhanced biometric-based person identification system that works robustly across a range of border crossing types and that has strong user-centric features. The system will be deployed in Automated Border Control (ABC) areas supporting border guards to facilitate smooth and non-intrusive rapid crossing by travellers based on deployment of the next generation of biometric identification detection methods. The ability for the system to efficiently process low-risk travellers, combined with increased levels of accuracy, security and privacy standards and enabling border guards to concentrate resource on higher-risk travellers, are central ambitions of the project. To achieve these goals, a multi-biometric enrollment and verification system is envisaged, taking into account current and next-generation e-Passport chips, mobile equipment and person identification on the move. Research will be undertaken into optimization of currently deployed biometric modalities, application of emerging biometrics (including contactless finger vein, speaker recognition and angthropometrics), multi-modal biometrics and counter-spoofing, for border control scenarios. An integral part of the project is collection and dissemination of new border-realistic biometric datasets, and systematic evaluation of the developed biometric methods including vulnerability and privacy assessment. The PROTECT project is strongly user-driven and demonstration of the developed biometric system will be conducted at two different border crossing sites. Finally, the PROTECT project will make contributions to facilitating border crossing of bona-fide non-EU citizens as well as evolving standards in biometric systems.
