		+	*I integrated the Fault Tolerance and the Delay Compensator. I tested the system after the integration on the cloud; the primary controller was at a VM in Singapore, the secondary controller was at a VM in Sao Paulo, Brazil, and the emulated plant was on my laptop at SFU. The results were fine for delay value up to 900 ms. The remaining issue now is that there are some occasional small spikes that appear in the system response and I am now working to figure out how to eliminate them.

-*I fixed the last week's issue. Also, I tested the whole system on the cloud with its two modes; the fault tolerance and the delay compensator modes. The results were fine when I tested the system on the cloud on near locations (e.g. at Oregon and California). However, for the further places (e.g. US east cost and Tokyo) and for large delays (i.e. >= 30 sampling periods), the system response in the delay compensator mode oscillates and it does not settle. I talked with Dr. Tamir about this and he suggested some directions to fix this issue and this is what I will investigate in my next steps isA.

		+	*I worked on the integration between the delay compensator and the rest of the system. The goal was to have one system with two separate modes; the Fault tolerance mode and the the Delay Compensator mode. I tested the delay compensator mode using our machines (through the internet) and the results were fine. However, when I tested the code using Amazon cloud services, the results were not the same! For example, when disabling the delay compensator and the estimated delay was around 25 sampling periods, the system response, when tested on the cloud, was almost smooth without any overshoots. So, right now I am working to figure out how to solve this.
