It's quite difficult to create 3D relief from plain 2D image. To provide a very clean 3D relief, lot of resources, like software programs, machines, tools and time, is needed. This study provide an optimized way how to enhance the 3D output without sacrificing other factors like the machining time and tool life. Image layout enhancing and the use of ArtCAM postprocessing were applied in the study. As compared with the traditional machining strategy, machine relief was added in the operation. From the results, this strategy helps in the preparation of the 3D model for the engraving toolpath and reduces its machining time operations.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117260695","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}

The results for the day module operation showed that insects responded to 80 Hz at 50 dB. For the night module, the most number of insects were attracted to UV, at 80 lux intensity.

The more interaction of the user with the machine, the more the user is prone to accident due to mechanical or tool failures. Like in CNC systems, especially in milling and router machines, user interaction can be seen during manual tool change operations. This study presents the development of an automatic tool changer for the 3-axis computer numerically-controlled (CNC) router machine of the Metals Industry Research and Development Center (MIRDC). ATC reduces the cycle time of tool-change operations, thus, improving the machine productivity. Furthermore, ATC also ensures the user's safety during tool change operations. It allows complete machining where different toolings are required to make different operations like cut, engrave, drill and mill. This includes the use of a pneumatic or quick-change electrospindle and an ISO-20 tool holder system. The tool holder system makes the CNC router adaptable and flexible to different routing operations.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116208053","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}

The accuracy of the estimates can be improved by using an adaptive filter called least mean squares algorithm (LMS) to reduce the effect of noise and carrier leakage before the extraction is done. Through the use of a simulation, random complex signals are primarily set from angle bearings of -90 through positive 90 degrees, inclusive of carrier leakage and noise, characterized as additive, white, random, and Gaussian-distributed. The LMS filter, with step sizes of 0.008, 0.003 and 0.002, is designed to detect the deterioration of affected parameters of the complex signal in order to reduce the inaccuracy of the estimates as effects of the added distortion. The accuracy of the estimates are compared to the actual DoA of the tag by measuring the error in degrees and with respect to the variation of the step-size. Simulations have also been done to observe the effect of signal-to-noise ratio (SNR) of the received signal and the increase of the number of samples taken before extraction, in addition to the variation of the step size of the filter.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121566116","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}

In this way data transmission will be quicker and data distribution will be faster. One of the famous P2P distribution systems is BitTorrent. BitTorrent has gained reputation by its remarkable performance in distributing large files over the internet. Since BitTorrent and other P2P systems were usually established at the user level, they do not perceive information from the network. We investigated and demonstrated here an approach of improving the BitTorrent by integrating network information in the protocol. We consider here latency. This can be very useful for network applications since it provides a way for higher level protocols to infer states and problems within the network. High latency values would mean congestion and instability of a node, in which we can perform decisions to handle traffic effectively in the network. We integrated latency as an indicator in the selection of neighbors in the peerset. Also, we conducted experiments with several network scenarios to validate our approach. Results show that with our method, 86% reduction in the download time can be achieved, thus indicating highly significant improvement in performance.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131767987","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}

Data is sent directly to the server via Wi-Fi, The second approach is used when Wi-Fi is not available since data is sent to another android phone via SMS. The second android phone is responsible for sending data to the database. The data collected were compared with actual sensors and past data recorded by PAGASA to test for the accuracy of the system.
