    Vascular injury and disease as well as cardiac and cardiovascular diseases have been a serious threat to human life and health today. Stents implantation have been the primary treatment for vascular diseases. Polymeric bioresorbable stents manufactured with 3D printer is newly emerged. This work review the bioresorbable stents and the utilization of additive manufacturing in bioresorbable stent manufacture.

    Machines condition analysis based on output machining parameter and vibration signal monitoring
    ( 2015)
    Mohd Shuhidan Saleh
    This dissertation reports an investigation on the machine condition for a group of similar milling machines based on vibration signal and surface roughness quality. This study is motivated by an issue in maintenance field where an appropriate technique has to be applied to monitor the condition of a machine. In this work, the machining system studied are the group of milling machines within the laboratory in the School of Manufacturing Engineering, Universiti Malaysia Perlis. To further understand the subject of studies, the extensive literatures has been done related to condition monitoring, vibration analysis and also the effect to the surface roughness. The application of fishbone analysis in identifying the possible causes of the problem also has been included in the review. In this work, the vibration level have been measured at three different points of the machines (ram, spindle and vertical head). These vibration level is then analysed to determine the causes of inaccuracy in the machining quality. From the experimental results, it is found that surface quality is strongly affected by the vibration. Machine 2 is found in critical state due to the highest level of vibration as compared to the other machines. Machine 1 and 8 have demonstrated the unusual condition where the vibration level is moderate however the surface roughness value is high and does not synonym to vibration trend. In the present work, the root cause for vibration and poor surface quality are performed by using fishbone analysis for the affected machine. The findings are discussed and the conclusions reached in this project and recommendations for future work are enclosed

    The most fire-related fatalities are due to the smoke inhalation of the toxic gases. It is related to the victims being trapped in the building when the building was on fire. It was also reported that major deaths from fire related are from the toxic gases inhalation produced by the fire while the deaths due to fire flames and burning was about one third of the total deaths. The access to the exit door was blocked and they could not exit through the window due to the permanent grille installation. It was well aware that most Malaysian homeowners installed grilles on their house windows or doors for security reason since there are lots of break-ins incidences. To overcome the issue, this work introduces a window grille with keyless locking system. The design incorporated keyless system that can be operated or opened without a key. Several designs for implementing this solution have been described. These designs are divided into three sections, which is a grille design, expansion designs which use to accommodate a wide range of window-sized and keyless locking systems. The size and type of grille suitable for Malaysian residents as well as the more efficient keyless locking system has been studied in detail using the method of case study and survey method. Step of patent research, market analysis and benchmarking are used as methods for collecting reference data. The most effective fire escape window grille keyless locking system has been studied and designed from this project. An important factor in designing a fire window grille is the design that can be opened and does not require a key operation. The results of the design and analysis tested are presented such that they can be used as an aid to the design of fire escape features.

    The demand for coronary artery stents keeps rising every year with a higher quality, lower cost, faster and economical process. Due to its availability relatively low-cost price and adaptability, Polylactic-acid (PLA) has been identified as an ideal material for biodegradable stents. Previously, laser micromachining was widely used for processing coronary stent but this manufacturing process required high investment. Apart from that, this process was unpractical and unfeasible to be machined with certain material and complex design. Alternatively, FDM 3D printing emerges as a system for producing stent and gained attention for its low cost, high reliability, simple operation, flexibility and has shown potential as promising solutions in stents fabrication. Stent length is one of the key aspects in stents manufacturing. In this work, optical microscope is used to measure the stent characterizations while processing parameter optimization was performed by using Response Surface Methodology (RSM). Printing orientation affects the stent length dimensional accuracy. Both XY and ZX are capable to develop PLA stents but XY-orientation is the ideal printing orientation as it provides good dimensional precision for stent characterizations and a lower risk for the structure and geometry to be sagging.

    Laser welding on dissimilar materials is widely used and has significance application in industry. Laser welding is the one of the method which can offer high strength of joint especially for joining of dissimilar metals contrast to conventional method. Conventional welding more often had an insufficient penetration depth and a wider heat affected zone which prompts to reduce joint quality. This work exhibits a weld possibility on low carbon steel and high carbon steel surface utilizing low power fiber laser in pulse wave modes. The objective of this research work is to investigate the influence of laser welding parameters of welding speed and pulse width on weld geometry of the welded metal. The parameters used is the welding speed (1.67 mm/s to 8.33mm/s) and pulse width (3 ms to 5 ms). The optimum weld geometry was with the largest aspect ratio (1.42) with parameter of welding speed (1.67 mm/s) and pulse width (3.0 ms). As conclusion, appropriate utilization of parameters can improve the quality of weld joints and durability of products.
