However, due to the sintering process, the parts are very porous and have poor mechanical properties when compared to injection molded, cast, or machined equivalents. Thus, there is an opportunity to develop post treatment processes to reinforce these structures. In order to predict the possible improvement in mechanical properties, the shape, size, and permeability of the pores needed to be characterized. This study captures the baseline tensile mechanical properties, and investigates the levels of porosity via fluid penetration and optical tests. Parts were immersed in both high and low viscosity substances to fill the pores, so as to investigate the extent of penetration, and thus, observing porosity levels. In order to achieve greater penetration levels a vacuum was applied to evacuate the entrapped air, causing the fluid to be adsorbed readily. Initial results showed that nylon SLS specimens are inhomogeneous in terms of porosity levels i.e. the density in different areas of the specimen can vary. Capillary action was found to be insufficient to penetrate the internal structure of a SLS specimen, though the vacuum technique can achieve far superior levels, to multiple mm of penetration.","PeriodicalId":125468,"journal":{"name":"2016 23rd International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127849748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, at the same time, it is still experiencing obstacles, such as confined working space, the absence of force feedback information and lack of visualization etc. The spinal cord and spinal nerves connect the brain with the rest of the body. They are quite vulnerable and small damages on them may lead to severe body dysfunction. This paper presents that using Raman spectroscopy as an analytical tool to identify spinal cord and spinal nerves from surrounding tissues for MISS purpose. Ex vivo Raman experiments is done on swine backbone samples with a fiberoptic Raman sensing system to examine the viability of this work. A total number of 750 raw spectra of bone, fat, muscle and spinal cord are obtained and data pre-processing procedures are employed before multivariate analysis. Principal Component Analysis (PCA) are then applied for data dimensionality reduction. Finally, classification model (together with 10-fold cross validation) using linear discriminant analysis (LDA) for multiple classes is built based on the PCA results and an overall accuracy of 93.1% is reached.","PeriodicalId":125468,"journal":{"name":"2016 23rd International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124059732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to DC plasma torch has high energy density, it is widely used in the field of plasma spraying, metal cutting and welding, waste treatment, and gas production etc. This paper presents a new DC plasma torch structure with a high-frequency arc ignition circuit which is capable of generating laminar plasma flow. The plasma torch in this paper has multiple electrodes including a water-cooled cathode, a water-cooled middle electrode and two water-cooled anodes. For convenience, compressed air is chosen to be working gas. The air intake method is designed to be rotating to get a more compressed plasma flow. The diameter of electrodes gradually increases along the direction of the plasma jet. A new cathode structure is designed in this paper. The arc is ignited between the cathode and the middle electrode. After the compression of the first and second anode, the plasma jet is stable and laminar. Besides, a new arc ignition circuit is designed which can be coupled into the main power circuit in series connection. A high-voltage and high-frequency arc ignition circuit is designed to generate the arc. The designed working voltage is 100V and the working current is 50A which is the critical current of thermal plasma.","PeriodicalId":125468,"journal":{"name":"2016 23rd International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127626548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
