Overview of Atlantis
Architecture of Atlantis Server
Obtain Model Information
Obtain event
Use Creator to model the problem
Provide the process to server
NO
Process event?
Send back to event Queue
Server generates a controller for the process
YES
Controller will control the FSM for that process
Process Complete !!!
15
Overview of Atlantis
Architecture of Atlantis Client
Client connects to respected Server
Obtains the model from Server
Obtain event
Client generates its own controller
NO
Process event?
Send back to event Queue
A User Interface is created
YES
Interaction with User Interface creates an Event
Process the event !!!

WiMop Overview

• WiMop Application
• Road Weather Information System (RWIS)
• Demo
• Work in progress

17
WiMop Application

• Dr. Aly Sherif and Dr. Yasser Hassans Research
  Work
• Modeling Pavement Temperature for winter
  maintenance
• Smooth and safe traffic flow
• Reduce Cost and Resources

18
WiMop Application

• Control of snow and ice formation
• Study relationship between surface temperature
  and weather variables
• Surface temperature determine effectiveness of
  particular deicer.
• Dew point determine ice formation.

19
WiMop Application

• Road Weather Information System (RWIS)
• Installed to collect data for weather prediction.
• Composed of 3 components
• Sensors
• RPU
• server

Yr 2001-2002
22
WiMop Application

• Sample Data
• Dew Point readings
• 80000 lines
• Collected between 2001 2002

23
WiMop Application

• Our Task
• Eliminate inconsistencies in the Sensor Readings
• Detect Defective Sensors
• Improve Performance

• Our Approach
• Database method
• External File method

24
WiMop Application

• Database Method
• Import data to PostgreSQL database
• Used ODBC (Open Database Connectivity)
• Uses EXCEL as the Data Source
• Atlantis Server is used to import data into
  PostgreSQL

25
WiMop Application

• External File Method
• Direct access to file
• No ODBC connection
• Uses Text file as the Data Source

More Efficient

RFid Overview

• RFid System
• Typical RFid Architecture
• RFid Application
• Conclusion
• Questions Answers

37
RFid System
Radio Frequency Identification (RFid) Is an
automatic identification method, relying on
storing and remotely retrieving data using
devices called RFID tags or transponders.
http//www.wikipedia.org Is one of the
hottest emerging technologies today.
38
RFid System

• History
• Developed in 1935 by Scottish physicist Sir
  Robert Alexander Watson-Watt
• Used during WWII to identify aircraft
• Continued Advancement
• Auto ID Center was created in 1999

39
RFid System

• Applications
• Anything that can be identified can use RFid
• Big in Wal-Mart and the US Department of Defense
• Big in retail and supply chain
• May eventually replace barcode technology

RFid Application

• Our RFid Application is to reduce waiting time at
  Ski lifts

45
RFid Application

• Required Components
• Passive RFid Tag
• Antenna
• Reader
• Power supply and interface cables

46
RFid Application

• Each skiers will be tagged using Passive RFid
  Tags
• Tag would contain a unique ID
• Information stored in a database
• Reader reads the ID of skiers in range
• Validates the ID
• Opens the gate
