In evolution and ubiquitous computing systems, accelerometer-based human activity recognition has huge potential in a large number of application domains. Accelerometer-based human activity recognition aims to identify physical activities performed by human using accelerometer; a sensor device attached to the body and returns an actual valued estimate of acceleration along the x, y-and z-axes from which the sensor location can be estimated. In this study, an accelerator-based activity recognition model using voting technique was proposed. Two machine learning classifiers, Naïve Bayes Tree (NBTree) and Multilayer Perceptron (MLP), were used as ensemble classifiers in the voting technique. To evaluate the proposed voting technique, the performance of selected individual classifiers and existing voting technique was first examined, followed by the experiment to determine the performance of the proposed model. All of the experiments were performed using a standard dataset called Wireless Sensor Data Mining involving six physical human activities; jogging, walking, walking towards upstairs, walking towards downstairs, sitting and stand still. Results showed that the proposed voting technique with NBTree and MLP ensemble classifiers outperformed other individual classifiers and another previously suggested voting technique for accelerometer-based human activity recognition.

The teaching profession is filled with countless opportunities to enrich the academic lives of students. While some concepts and educational objectives will be easy for students to grasp, others will require you to think creatively to ensure that important learning objectives are met. Using audio/visual aids in teaching is one way to enhance lesson plans and give students additional ways to process subject information. Bridge the gap between the different types of learners by adding audio/visual aides to your teaching techniques. Since most people are visual learners, it's important to go beyond "spoken words" when educating students. Students are also more likely to learn material is they're exposed to it in a variety of ways. Always look over your lesson plans to find ways to inject different teaching styles. Implement "show and tell" sessions to promote student involvement. This will also help you assess each student's overall understanding of the desired learning objectives. There are many ways to use show and tell sessions such as asking students to bring in modern items that still demonstrate colonial values. Watch videos and movies that reinforce lesson plans. Authors such as Shakespeare may be easier to understand when the material is seen as well as read. Use film clips to highlight historical events and to provide expert analysis of current situations.
