Abstract: Technology of 3D-Printer based on fused deposition material has developed intensively with varying qualities. However, default setting of printing process parameters provided by the manufacturer in some cases does not guarantee quality (dimension error and strength) of the printed part, since there are several process parameters that need to be considered. A 3DPrinter with poly-lactic acid filament material has been applied in this study. A specimen standard has been used as a tensile strength and dimension error test to represent printed part quality. Three printing process parameters: layer thickness, layer speed and infill density have been optimized using Taguchi L9 Orthogonal Array method. In a recent project, we have thus investigated possibilities to increase the printability of especially flexible filament. The presentation will give an overview of the modifications and their effect on the most frequently used elastic filaments, offering suggestions to modify common 3D FDM printers in similar ways for increased printing results with or without integrated fibres or filaments.

Abstract: In Hungary, the quality of lower class roads is inadequate in many cases. Road irregularities cause different vibrations in vehicles. It is important to examine the vibrations generated in vehicles by a given road section as they can lead to a reduction of lifetime or even an immediate failure of suspensions and other structural components. Recently several fire trucks with special vehicle body have also experienced structural failures which have possibly been caused by vibrations from road irregularities. To prove our assumption field measurements were carried out with the Csepel-Metz 755-10 heavy duty fire truck on a selected road section. In this paper the results of numerical simulations and field measurements with a special fire truck is presented. The aim of our research is to draw attention to the importance of the topic and to contribute to the safe operation of fire-fighting vehicles.

Abstract: The industries have become more competitive in nature due to the technical research and development which made the industries to improve their productivity to meet their market demand. The industries started to invests more on machines for high productivity, but when the machine is not working properly then these machines has to be get repaired and it leads to breakdown hours and the manufacturers has loss in their productivity. So in this paper a solution has been suggested for reducing the break down hours of milling machine. This can be achieved by reducing the breakdown hours of the milling machines. Milling machine performs various machining processes like milling, grinding and boring etc. on the work piece. So to avoid this, Root-Cause Analysis of these defects is carried out and the modifications are to be done as per the results of analysis. Root cause analysis for milling machine is conducted to find the root cause of machine for breakdown time and some parallel improvement opportunities were also identified for implementation so as to reduce the breakdown time of machine. The project thus aims to minimize breakdown time and maintenance cost with maximum availability and profit, increase MTBF & decrease in MTTR. Finally to prevent the failure of equipment before it actually occurs.

Abstract: Crisis Management is the choosing of an organized process, that is reasonably cost effective, in order to lessen certain threats facing the organization or company. It is a process coupled with the principle of sustainability. It is a measuring process, and one used to evaluate threats, and develop a strategy to manage it. These strategies include moving the threats elsewhere, avoiding them, and decreasing their negative impact, and accepting some or all of its effects. It indicates two options one which can occur. Undoubtedly the cases whereby there is only one chance are the cases where there are no threats. They are occurrences and events threaten the realization of goals, and could have a negative impact on the continuation of the work, thus making the crisis management a real art undertaken with competence, professionalism and experience. Threats are the chance that a company could face unexpected and unplanned losses, or could make the anticipated revenues fluctuate.

Abstract: In industries, wide variety of machines is performing variety of processes. Corrective maintenance is a maintenance task performed to identify, isolate, and rectify a fault so that the failed equipment can be restored to an operational state. The main focus of the paper is to alert on breakdown occurrence and to display the machine status visible in one view and also to calculate machine performance to improve machine efficiency. As soon as the fault/breakdown occurs it should be conveyed to responsible person, sooner we can convey the problem; the lower the communication time loss and sooner the equipment breakdown handled lower the production time loss. So we have developed an instant approach in industrial equipment breakdown handling via SMS which results in 1) Real time machine breakdown status monitoring using IoT 2) Alert System for effective communication 3) Visibility of all machines in one view for transparency in working. This kind of approach will lead to a unique system with different solutions along with Internet of things.

Abstract: Geochemical survey of residual soils to explore for ferrous metals in the more prospective Dagbala-Atte District of Igarra Schist Belt, South western Nigeria was undertaken. The study involved sampling of residual soils from 49 sites; geochemical analysis of the soil samples for 9 elements, namely, Co, Cr, Fe, Mn, Mo, Ni, Ti, V and W; and subjecting the geochemical analytical data to both qualitative and statistical analyses which include univariate (histograms and box plots), multivariate statistics (correlation matrix and factor analysis) and construction of geochemical distribution maps. By determining the threshold for each element using the univariate plots, it was possible to isolate elements having anomalous values which were compared with their background concentrations in the World's soils. As a result, only four of the ferrous metals subjected to statistical studies, viz, Co, Cr, Ni and V, were found to have significant anomalous values and are suspected to be mineralized in the district. On the basis of correlation matrix and factor analysis, three groups of element association were recognized, viz, Cr-Ni-V-Ti-Fe, Mn-Co-Ni and Mo-Fe-V groups. Only one suspected mineralization, viz, Cr-Ni-V mineralization and a Co-Ni anomaly were inferred to be present in the Dagbala-Atte District. With the aid of the elemental geochemical distribution maps the suspected Cr-Ni-V mineralization was linked to the sheared, silicified rock at the northern and southern parts of the district while the suspected Co-Ni anomaly is linked to the quartz-biotite schist at the southwestern part. Based on the foregoing findings, it is recommended that lithogeochemical survey be carried out in the areas circumscribed for the suspected mineralization and anomaly of Cr, Ni, V and Co in the district.

Abstract: The increasing amount of research on watermarking over the past decade has been largely driven by its important applications in digital copyrights management and protection. Digital watermarking is the act of hiding a message related to a digital signal (i.e. an image, song, video) within the signal itself. It is a concept closely related to steganography, in that they both hide a message inside a digital signal. However, what separates them is their goal. Watermarking tries to hide a message related to the actual content of the digital signal, while in steganography the digital signal has no relation to the message, and it is merely used as a cover to hide its existence. With the emerging of low cost 3D display devices, different kinds of 3D applications and the amount of 3D content are booming up, recently. Effective digital watermarking systems for 3D content protection will play an important role for developing and promoting the 3D entertainment industry. The proposed 3D watermarking technique employs the method of slice extraction from a 3D volume. An obj file is used and the wave front object data is obtained.DWT technique is used to embed the secret binary data into one of the extracted slices. The inverse operation is performed at the receiver using the same secret key used at the transmitter. Finally, the watermark is extracted and the quality measures of the reconstructed image is calculated.

Abstract: Synthetic Aperture Radar (SAR) has been widely used in many civilian and military applications, and the SAR with moving targets indication is a very hot topic in recent years. As many literatures discussed, if the returns from moving targets are processed in the same way as the stationary returns, the moving target will appears as an azimuth shift due to range motion and the image of the target will be smeared in the azimuth direction due to azimuth motion .The high-resolution interferograms over vegetation or urban areas are heterogeneous, which will violate the local stationarity assumption and make it difficult to obtain a large number of independent and identically distributed samples for interferometric noise suppression.
