The Bosch BNO055 IMU sensors come with the software package that consists of sensor drivers. In order to let the sensors to give data, these drivers should be added in the Arduino software library folder inside the computer. The driver is capable of giving the raw sensor data by using the sensor library in the Arduino code. The Arduino library used for this purpose was ‘Wire Library’, which allow communication with I^2 C devices. This library can be manually downloaded and added to the Arduino folder. After adding the library, the code can be run and compiled to get the raw values from the sensors.

The function accepts a single vector_type parameter at a time and returns 3-axis data of the selected parameter. The vector_type can be of the following parameters state below. IMU sensor BNO055 was the vector_type_t for this purpose. VECTOR_MAGNETOMETER (µT) VECTOR_GYROSCOPE (rad⁄sec) VECTOR_EULER (degrees) VECTOR_ACCELEROMETER (m⁄s^2 ) VECTOR_LINEARACCEL (m⁄s^2 ) VECTOR_GRAVITY (m⁄s^2 ) The sensors are capable of transmitting the orientation data in both Euler and Quaternion angles depending upon the function used. As the requirement of this project is concerned, the values from the vector function we were concerned was VECTOR-EULER (degrees) and was VECTOR-GYROSCOPE (rad⁄sec). From these functions, the required data needed was inclination, angular velocity and linear acceleration. For inclination, we directly used the Euler vector function which gives data in 0-359 ͦ. For angular velocity, vector gyroscope function was used. This function directly gives data in rad⁄sec which was required for finding angular velocity of the sensor. Finally, for linear acceleration, function called vector linear acceleration was used. Figure below shows the VECTOR-EULER function used for getting the required inclination values from the sensor. The code was written in Arduino …show more content…
It loads a 3D model in an ‘.obj file’ format and converts the data from the sensor to a sketch on the microcontroller. The sketch on the UNO gives the data over the UART (Universal Asynchronous Receiver/Transmitter), which is based on the incoming orientation data from the sensor. The bunny program from the sensor library is first uploaded from the Arduino to the serial port. For visualizing the data, Processing 3.0 software is used which converts the data to 3D visual. It uses the OBJ library and G4P GUI library to visualize and process data to a bunny sketch. On the GUI of the sketch, available ports are mentioned where the serial port can be selected. This port should be selected the same as that used for Arduino serial interface. After selecting the port, the program is run and a bunny appears on the window. As the breakout board is rotated, the bunny rotates in the same manner in a 3D space. This test shows that the fusion algorithms are working in the correct way to give the orientation of the sensor in 3
3.1.8 TACA The objective of TACA is to choose a minimum number of cluster heads to decrease the number of nodes in the virtual backbone. The characteristics of TACA are: • The nodes in the ad-hoc network are able to increase or reduce their transmission coverage range. However, there is a maximum range R max. • Nodes mobility and Battery power are considered as a weight deciding factor.
‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.
I began collecting data by contacting the IT technician of Bru-Hims. It was quite difficult to get a response because the IT technician is being deployed out of the office to each health facility on a daily basis. I have gathered a list of questions specifically for the IT technician. Beforehand, I wrote down the questions on a piece of paper before implementing it into Microsoft word. I organised a meeting with them until they finally agreed.
Vitamin B12 (Cobalmin) is a water soluble vitamin and plays a key role in the normal functioning of the brain and nervous system, and in the formation of red blood cells. Vitamin B12 deficiency can occur if the body does not absorb enough vitamin B12 from the gastrointestinal tract or when there is not enough dietary intake of the vitamin. One common cause of deficiency is as a result of pernicious anaemia which is an autoimmune disorder that results in inflammation and damage to the stomach lining, and loss of parietal cells. The parietal cells produce intrinsic factor, a protein needed for absorption of Vitamin B12 in the gut.

In order to do hardening system on any type of software computer you would have to look at the type of location that your network is going to be installed in after you fine or survey the following location then you would definitely get a location to where you would like to place your hardware to install your firewall systems once you get the physical aspect of your file systems installed you would then have to look at how setting up the software passwords on most computers or on your security system on the network then you would not stop there because you would have to keep access controls established on the location to make sure that physical security of the location does not hinder anyone from trying to get into the location that has authorized
Outcomes The web application was well received by all the stakeholders. The support engineers were excited to see a centralized location for transfer requests and avoid communicating through email. Since there were multiple transfer request handlers for each product, the processing for each request was quicker and the management was able to quickly measure real time success. It was realized that there could be additional improvement to make the process even faster by implementing a distribution list for the transfer request handlers for each product, for a more focused notification, instead of notifying all the handlers.
What Kayden and I did first is get on EV3 robot out and connect it to bluetooth, after that we did that we started to think about how we were going to find out how many rotations that we were going to need to get it from start to finish. So, we got a ruler and since we already knew one rotation was equal to 7 inches we guesstimate that it would be about 5 rotations. When we tried it is was still a little short of its goal, so we added 0.5 to it and it barely went over its goal. Finally we took away 0.08 and tried it and it landed exactly on its target. So our final solution was 5.42 rotations at 27% would get us from the start to the finish exactly.
Asking questions about strategies and services use could cause students and colleagues to become defensive, because they may view it as questioning their commitment or abilities. Examining one’s own teaching practices can reveal flawed ideologies and practices. This discomfort can be further complicated by the formalization and examination of techniques used to collect and assess research data. Collection concerns include access to and cooperation by the participants. The time constraints and additional workloads caused by the data collection and analysis create other potential problems.
For the second part of the lesson 14 assignment, I chose option 2 which is the design part. I used the Glogster tool, an interactive learning tool that can embed images, files, videos, arts, text, audio and data to a virtual canvas. In fact, the tool is design primarily for teachers of elementary schools to help students learn more effectively. I was surprised how user friendly it is and you can simplify your essay by using it. Also, I mainly used videos from YouTube to supplement by text and it came out as a child friendly presentation.
The VideoRay’s proprioceptive sensors include a compass, accelerometer and gyro, a leak alarm, voltmeter, temp sensor, and depth guage (VideoRay, 2012a). The exteroceptive sensor for this operation was a wide range, standard definition color camera with a 160º tilt. Aided by

In all experiments, observers viewed two rotating structure-from-motion (SFM) objects. Spherical and “gear” shapes were used in Experiment 1. Spheres only were used in all Experiments 2 and 3. All experimental conditions for Experiments 1 and 3 are illustrated in Videos 1-31. Experiment 1 Two types of shapes – a sphere and a gear – were used in Experiment 1 (see Videos 1-30).
