Emergencies can occur at any location and time, so all stakeholders should get themselves prepared for providing emergency actions and responses. Such actions are especially important in sophisticated but vulnerable systems, e.g., mass transport systems, hospitals and power plants. Crichton and Flin [1] showed multiple examples that the performance of incident management teams in the initial stage of a crisis could affect the development of the incident. Therefore, regular training should be provided to the stakeholders, particularly the operators of the organisation, so that they can work together to deal with the emergencies effectively. Although conducting a drill in the real system may be the most direct way for stakeholders to practice their emergency response abilities, performing a drill usually requires many resources and a disruption of the real system. Therefore, this paper introduces an approach to conduct the drill in a virtual environment. It proposes a virtual collaborative simulation-based training system with an aim to improve the emergency management ability of the staff in sophisticated but vulnerable systems. There are four major advantages of the proposed system: 1). It is off-line from the real system so that there is no space or time constraint to carry out the training. 2). It requires fewer physical resources to carry out the training, which makes the training much cost-effective. 3.) The managers, as well as the operators, can have a better understanding of the real operations by looking at the 3D simulation model. 4.) It provides flexibility to train the operators in various hypothetical scenarios, including some rarely occurred ones. To better illustrate the ideas, this paper takes the mass transport system as an example. However, it should be stressed that the proposed system can be applied to other areas like exhibition centres, emergency rooms of the hospitals and nuclear plants.

The paper deals with the speech processing and adaptive filtration. Introduced application is implemented in both online and offline mode in LabVIEW. The online mode program is used to create a database of speech recordings and various interferences from the outdoor environment as well as from the home. The offline application then serves to test adaptive algorithms for the needs of speech processing. The criterion for comparing the efficiency of individual algorithms is primarily to increase the signal to noise ratio. To test the filtration rate, a global SNR method was chosen.

Nowadays, companies and organizations pay more attention to the use of open source software. In this regard, organizations can benefit from the advantages of this kind of software, such as less cost and more flexibility. However, migration to open source software has its own risks, such as training of employee, lack of compatibility, and support. Reviewing numerous papers found in the literature, this study aims to collect a complete list of risks that may influence the open source migration process as much as possible. It also provides a new categorization of the risks by which each risk is classified based on its type (organizational, technical, and environmental), and its time of occurrence (before, during, and after migration). Moreover, this paper proposes a number of conceivable measures to mitigate each risk; some of them are proposed for the first time in this area of research. The results of this study can help organizations' decision makers to make better decisions in the open source migration process.

The rise of social media usage in the form of multimedia is on an exponential increase owing to the increased internet bandwidths in the recent past. As a result, people communicate in the form of videos and images a lot more than ever. One such video sharing and content developer platform is YouTube. YouTube has many features on video analytics in the form of recommendation systems, monetisation etc. It also offers many features for developers to evaluate their content and offers insights on the performance of their videos. Though these features are available, there is not even a single feature for developers to evaluate their content based on the performance of other's videos, which share the same nature of the content - the similarity between any two videos. Here, the similarity between two videos has a statistical measure apart from the content, which includes description and comments of a video. Thus, we propose an analysis of a query video and a range of videos to determine the most similar videos using statistical and textual similarity. The statistical similarity is evident from the number of derived features extracted from a video and the textual similarity is found by analysing the text data from the description and comments of a video. Experimental results show that the resultant similar videos are highly representative of both the statistical and textual similarity and can be used as a measure to compare two videos.

The Discrete Element Method (DEM) is a Lagrangian approach initially developed for predicting particles flow. The eXtended Discrete Element Method (XDEM) framework, developed at the LuXDEM Research Centre of the University of Luxembourg, extends DEM by including the thermochemical state of particles, as well as their interaction with a Computational Fluid Dynamics (CFD) domain. The level of detail of its predictions makes the XDEM suite a powerful tool for predicting complex industrial processes like steel making, powder metallurgy and additive manufacturing. Like in any other DEM software, the critical aspect of the simulations is the computation requirement that grows rapidly as the number of particles increases. Indeed, such burden currently represents the main bottleneck to its full exploitation in large-scale scenarios. Digital Twin, a research project founded by the European Regional Development Fund (ERDF), aims at drastically accelerate XDEM through different approaches and make it an effective tool for numerical predictions in industry as well as virtual prototyping. The Multiphase Particle-In-Cell (MP-PIC) method has been introduced for reducing the computation burden of DEM. It has been initially developed for predicting particles flow and uses a two-way transfer of information between the Lagrangian entities and a computation grid. The method avoids explicit contact detection and can potentially achieve a drastic reduction of the time-to-solution respect to DEM. The present contribution introduces a multiphase approach for predicting the conductive heat transfer within a static packed bed of particles. Results from a test case are qualitatively and quantitatively compared against reference XDEM predictions. The method can be effectively exploited in combination with MP-PIC for predicting the thermochemical state of particles.

It is necessary to establish the longitudinal dynamic model of the tractor for the cruise control system to design a fixed speed control algorithm according to the characteristics of the model and the external disturbance characteristics. Aiming at the complexity of the longitudinal power transmission system of the tractor, this paper uses the modular mechanism modeling and the experimental data modeling to establish the longitudinal dynamic model of the tractor. Due to the nonlinearity of the longitudinal dynamics system, the inverse model method is used to linearize the model, which is convenient for the design of control structure and control algorithm of the standard cruise control system. The longitudinal dynamics model is simulated on Simulink, and the model is verified by real vehicle under driving condition. Comparing the simulation data with the experimental data, the results show that the model can accurately reflect the longitudinal dynamics characteristics of tractor, and can meet the requirements for the design of cruise control system.

Machine Learning allows systems to learn and improve automatically from experiences without hand-coding. Thus, in recent years, many technology companies have been developing such application if Artificial Intelligence, from face recognition by Facebook, to the AlphaGo program by Google. The irrigation systems in the market nowadays mostly allow users to set them to a certain amount of water and at specific time intervals. However, there are usually more than one type of plants in a garden, and each species requires different amount of water. In order to resolve this issue, in this paper, we have developed an irrigation system, with the use of deep learning, that is able to adjust the amounts of water foe each type pf plant through plants recognition. There are two main parts of the solution, the software and the hardware. The prior is connected with cameras to undergo plant recognition, and utilizes database to find the suitable amount of water; the latter controls the amount of water that is able to flow out.

Blind image steganalysis is exploring body of digital images for the likely presence of hidden secret messages without knowledge of the employed steganographic technique. This paper proposes a novel image steganalysis technique to attack spatial domain LSBR stego images. The chosen steganalytic feature is the relation between length of the embedded message and the regressed proportion of intensity identical pixels and color channels. A trained SVM analyzes the pixels and the final decision is made based on union of the pixel analysis results. In SW, a number of innovative contributions are made to the field of blind image steganalysis. First, measuring pixel and cannel color correlativity as steganalytic feature. Second, defining pixel membership degree, thereby the pixels gain different level of influence on the process. Third, generating six references for statistical patterns of cover and stego pixels. And fourth, achieving 99.626% steganalyzer sensitivity on 0.25bpp stego images by only two analysis dimensions.
