In this paper, a 3D object retrieval method is proposed using multiple features and manifold ranking. Five descriptors are concatenated to be a new feature vector of length 792 for 3D object retrieval. They are angular radial transform-based elevation descriptor(ART-ED), principal plane descriptor(PPD), 3D-angular radial transform(3D-ART), shell grid descriptor(SGD), and Grid Distance 2 (GD2). Next, a manifold ranking method is used to re-rank the retrieved results. In addition, various distance metrics are addressed in the construction of manifold graph. The retrieval results on a benchmark dataset SHREC-W have been reported to show the feasibility of the proposed method.","PeriodicalId":262562,"journal":{"name":"2015 8th International Conference on Ubi-Media Computing (UMEDIA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123599714","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 keynote, we will review the recent trends and advancements in distortion-invariant pattern recognition followed by the development of a novel data fusion algorithm for single/multiple object detection and tracking in FLIR imagery. Each detection/tracking algorithm utilizes various properties of objects and image frames of a given FLIR sequence. The data fusion algorithm employs complementary features of two or more of the aforementioned algorithms to achieve significantly better detection/tracking accuracy. Test results using real life FLIR image sequences confirm the effectiveness of the proposed technique.","PeriodicalId":262562,"journal":{"name":"2015 8th International Conference on Ubi-Media Computing (UMEDIA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115536015","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 challenge is to adapt and position the gripper according to a target object. In this work, by considering a three fingered robotic gripper with a finger structure similar to that of human finger, we study the positioning of fingers in a gripper in the two dimensional plane. Using an inverse kinematic model for a pulley based underactuated mechanical finger, we derive a region of reach in the plane of the finger. Simulations demonstrate the limits of reach under different conditions. This can be used to derive the positioning of each finger, as well as in path planning to control the reach of the gripper.","PeriodicalId":262562,"journal":{"name":"2015 8th International Conference on Ubi-Media Computing (UMEDIA)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122665781","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}

But since the 1985 until 2010, the classification models have been shifted toward other four factors: (1) average years of schooling attained, (2) percentage of population completing primary school, (3) average years of tertiary schooling attained, and (4) percentage of population completing tertiary school.

The program will draw a sphere in three dimensions space by OpenGL and a user can dance in the visual sphere. The user can trigger events by entering two hands or feet in a specific zone and events will generate music or chord. The sphere can be 360 degrees rotated and we can see the 3D skeleton on the screen. We also calibrated two Kinects to do calibration because when user cannot stand in front of Kinect or when user stand side face to Kinect, Kinect cannot detect user's body very well, user's body will block by a part of your arms or legs and Kinect's infrared ray can't measure your joints. The reason we need to do a calibration if we need a side view of skeleton. We calculate the radius of the sphere when the user's hand on the surface of the sphere, it will generate sound by MIDI events. We use the program to perform in concert, which combine all virtual instruments in real time and show the 3d sphere with the user's skeleton on the screen.","PeriodicalId":262562,"journal":{"name":"2015 8th International Conference on Ubi-Media Computing (UMEDIA)","volume":"73 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131521691","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}

Numerous reasons may account for poor teacher involvement while the review of literature has indicated that perspectives of teachers in this context could be one of them. The purpose of this study was to model the perspectives of secondary school teachers regarding the integration of ICT in their instructional process. The research methodology adopted is Interactive Qualitative Analysis, which is an analytical framework for qualitative research and is formulated to make a systems approach to the problem under study, to model the perspectives of teachers about the integration of ICT in the classroom. Through focus groups and individual interviews, ten affinities: Principal, ICT Laboratory, Teacher-in-charge of ICT Laboratory, Student, Curriculum (Non-ICT), ICT Knowledge, Pedagogical ICT knowledge, Time, Non-ICT Teacher and Professional Development Program emerged to describe the teacher perspectives. Study of pair-wise influential relationships of the affinities identified the Principal as a primary driver and the Non-ICT Teacher and the Student as primary outcomes.

The statuses of students and the classroom are detected by wireless sensors, and these statuses will be transferred to the management system built in a server. The management system will determine the current conditions of the students and the classroom, and give proper feedbacks to the students, the teachers, and the wireless sensor-controlled equipment deployed in the classroom. The proposed intelligent classroom management system includes three subsystems. 1) The environment management system regulates the classroom to a suitable condition for teaching and learning; 2) The instruction mode management system assists teachers to switch instruction modes quickly and smoothly to avoid wasting of time; 3) The learning behavior management system alerts students when they are inattention or fatigued.
