Grading Scheme

The grading scheme for the course, as well as links to specific requirements for each assignment/deliverable and evaluation sheets, are given in the table below. Due dates for each assignment/deliverable can be found on the course Calendar. Please note:

There is a 25% penalty per day for any late submissions. "Late" means handed in after the deadline. Thus, if the deadline is 5pm and you hand in an assignment at 5:01pm, you will be penalized. The penalties are cumulative. If an assignment is due at 5pm on Monday and you hand it in at 5:01pm on Tuesday (two days late), your grade will be (1-25%)^2 of the grade you would have received had you turned it in on time.

Some assignments are "Individual" and team members are individually responsible for completing the assignment on time and will receive an individual grade. Many assignments are "Team" assignments and a single deliverable is handed in by the team. In most cases, all team members will receive the same grade on these assignments. However, the course staff reserves the right to "break up" any group's work and grade individually. This will be done if we feel the work or work quality has not been evenly distributed between group members.

The evaluation sheets provide a sense of what we are looking for with each deliverable. You should keep in mind, though, that the evaluation is not strictly binary. In other words, just because you have "checked off" each component described in the evaluation sheet does not ensure that you will receive a perfect score.

Below is the points breakdown for all assignments/deliverables for the course, sorted chronologically:

* Grades for these will be the average of the TA and Instructor grades; peer review grades will be used to provide feedback.
** Evaluation Sheets are subject to minor changes.

**Problem**

For public bike users, someone may concern about the air quality in which they are currently riding, as well as the places they are going to. However, currently there is no such an air quality monitoring system which provides air quality information in specific areas inside a city such as Haining.

**Solution Overview**

The idea is to apply air quality monitoring devices on the public bike system. The public bike system in Haining is a perfect carrier for IoT (Internet of Things) devices and urban sensing since it has a large and stable user group and all bikes are managed by official organization which means unified modification on all bikes can be done. A monitoring device integrated on the bike can provide the real-time information that users want to know and share data with other users through a cloud server. A real-time air quality map can be created for users with the contribution from all running bikes.

**Solution Components**

Subsystem 1 – on-bike air quality monitoring device. The subsystem is a stm32 microcontroller based design, integrated with air contaminant sensor, speed meter and data transmission modules. Once connected to a smartphone, the subsystem will keep transmitting real-time data to the smartphone.

Subsystem 2 – Software include a user interface and a server. The user interface can be either an app or a website on smartphone. The user interface receives sensor data from the hardware subsystem, displays the real-time statistics, uploads sensor data to server and receives the air quality map from server. The server processes data from all running bikes, creates a real-time air quality map and returns it back to users.

**Criterion for Success**

1. Success of data collection: stable real-time statistic display on user interface, stable data collection on server.

2. Air quality visualization: The air quality map correctly reflects the air quality in Haining city. For example, the concentration of air contamination should be higher in heavy traffic than in intl campus.

3. Speed control: The on-bike device or smartphone should give an alert when the monitored speed exceeds the upper limit or the user set range. This is not the core function of our design, but we add it as we think the function makes sense for safety purpose.
