Reliability engineering is relatively new scientific discipline which develops in close connection with computers. Rapid development of computer technology recently requires adequate novelties of source codes and appropriate software. New parallel computing technology based on HPC (high performance computing) for availability calculation will be demonstrated in this paper. The technology is particularly effective in context with simulation methods; nevertheless, analytical methods are taken into account as well. In general, basic algorithms for reliability calculations must be appropriately modified and improved to achieve better computation efficiency. Parallel processing is executed by two ways, firstly by the use of the MATLAB function parfor and secondly by the use of the CUDA technology. The computation efficiency was significantly improved which is clearly demonstrated in numerical experiments performed on selected testing examples as well as on industrial example. Scalability graphs are used to demonstrate reduction of computation time caused by parallel computing.

Chemical sensing based on fluorescence is presently undergoing rapid development. As one example, fluorescence lifetime measurements are now being used for measuring cation and anion concentrations in clinical chemistry, cellular imaging and flow cytometry. Additionally, there is an increasing use of proteins as sensors because of their high affinity and specificity for ligands.In this report we describe some recently developed approaches to fluorescence sensing. These new methods are based on the use of a fluorescence reference either within the sample or external to the sample, but within the optical path. Two types of references are used; microsecond lifetime metalligand complexes (MLCs) or oriented films of ns decay time fluorophores. A protein sensor for glucose was developed using the glucose-galactose binding protein (GGBP) from E.coli (Figure 1).

Age Range

Calibration is a core element of radiocarbon dating and is undergoing rapid development on a number of different fronts. This is most obvious in the area of 14C archives suitable for calibration purposes, which are now demonstrating much greater coherence over the earlier age range of the technique. Of particular significance to this end is the development of purely terrestrial archives such as those from the Lake Suigetsu sedimentary profile and Kauri tree rings from New Zealand, in addition to the groundwater records from speleothems. Equally important, however, is the development of statistical tools that can be used with, and help develop, such calibration data. In the context of sedimentary deposition, age-depth modeling provides a very useful way to analyze series of measurements from cores, with or without the presence of additional varve information. New methods are under development, making use of model averaging, that generate more robust age models. In addition, all calibration requires a coherent approach to outliers, for both single samples and where entire data sets might be offset relative to the calibration curve. This paper looks at current developments in these areas.

Physics-of-Failure (PoF) represents one approach to reliability assessment based on modeling and simulation that relies on understanding the physical processes contributing to the appearance of the critical failures. Firstly the connotation and meaning of PoF method were analyzed here, the inherence relation between PoF and reliability was expatiated, the PoF based reliability method and current reliability method based on probability statistics were compared, their differences and relationships were discussed here. Then the application condition of PoF method in reliability engineering in European and American developed country and China were summarized, the PoF based reliability engineering technologies were introduced systemically from several aspects, such as reliability design and analysis, reliability test and validation, maintain and support. Finally, combining with the developing characteristics of military materiel during the new period, some future investigation directions and application foregrounds were prospected.

Genotyping of important medical or veterinary prokaryotes has become a very important tool during the last decades. Rapid development of fragment-separation and sequencing technologies has made many new genotyping strategies possible. Among these new methods is multilocus variable-number tandem repeat analysis (MLVA). Here we present an update on the use of MLVA in eight European countries (Denmark, France, Germany, Ireland, Italy, the Netherlands, Norway and Sweden). Researchers in Europe have been active in developing and implementing a large array of different assays. MLVA has been used as a typing tool in several contexts, from aiding in resolving outbreaks of food-borne bacteria to typing organisms that may pose a bioterrorist threat, as well as in scientific studies.

Malaysia is the only country in South East Asia has local capability to manufacture car from concept until mass production. The manufacturing sector has contributed as the largest Gross Domestic Product (GDP) for Malaysian economy. Thus, the decision of new government elected on 2018 to start a new national car project is the best decision to boost manufacturing sector to the next level. Currently, involvement of Malaysian SMEs in automotive manufacturing sector is still small and this time needs to be improved. Thus, new methods are suggested to help more SMEs to take part in 3rd National Car Project. The Characteristics of Potential High Skilled Automotive Entrepreneur (C-POSITIVE) and Rapid Development of Automotive SMEs (RADAS) will help related government agencies to selected suitable candidates to be Malaysian automotive SMEs. Besides that, the authors have invented Blo-Wiper concept to improve conventional windshield wiper which is ineffective during heavy rain especially for countries located at equatorial climate like Malaysia. The Blo-Wiper concept using two rain droplets removing process; blowing and wiping shown significant result to increase driver visibility based on preliminary simulation study. This white paper is prepared by the authors to help Malaysian government in 3rd National Car Project.

Research and development in the field of the Internet of Things, or more generally M2M systems security, is the subject of daily discussion in the ICT market. With the rapid development of intelligent devices, the necessity of valuable information protection has generated many new methods and technologies. Stegoimages, along with genetic algorithms (GA), are a relatively new object in the field of information hiding. The assumption that their application can significantly improve the noise-resistant properties of stegofiles is justified by the properties of the GA, but it is a subject for detailed study, since in such an application the GA has not yet been considered. The proposed method is based on genetic coding that hides messages between Internet of Things devices and is capable of detecting both internal and external attacks in the intellectual infrastructure. A sufficiently high efficiency of preliminary GA coding is shown for objects such as hiding graphic information in a graphic stegocontainer.

Die schnelle Entwicklung von metallischen Konstruktionswerkstoffen in einem Hochdurchsatzsystem bedarf aufgrund prozessinhärenter Restriktionen neuer Verfahren zur Planung und Steuerung. Prozessflexibilität, strukturelle Änderungen sowie Wiederholprüfungen sind ursächlich für eine hohe Komplexität, die zur Durchsatzsteigerung bereits in der Belegungsplanung berücksichtigt werden muss. Zur Einplanung dieser Sonderprozesse wird eine Methode zur Steigerung der logistischen Ziele vorgestellt.   The rapid development of structural metallic materials in a high throughput system requires new methods for planning and control due to process-related restrictions. The planning must consider a high complexity caused by process flexibility, structural changes as well as repeat tests to increase the system’s throughput. A method for increasing the logistical goals is presented to plan these special processes.
