International Space station

I don't think many would have read the article from IEEE spectrum online regarding the latest failure of three main computers that control the orientation of the entire station. The reason given for the failure might seem a little bit silly but makes people wonder how such a small thing can can catastrophe of large scale. The reason was malfunctioning of dehumidifier. The dehumidifier in the control room should remove the water content from air circulated and keep the machines under condition where the water cannot condense onto any system. The reverse happened and has allowed for condensation. This has caused the rusting of the lead wires that are connected to the back up computers. The back up computers are used to protect the main system when there are spikes introduced in the system due to the power supply from the solar panels which are affected by cosmic clouds. Because of this rusting they became non-conductive causing the backup system not to work but the main system alone

Programming

I have been programming in VC++ for the past 8 hours. I really don't know now what i have programmed and whether this stuff is going to work the way it is desired. My program is a bit complicated one. The VC++ output cannot be immediately seen.This needs to be converted to PARAMICS compatible dynamic linked library files. And using the PARAMICS have to test it. The worst part is the PARAMICS just quits without really informing what went wrong. Hope i don't get much errors this time around. Tomorrow is a crucial day for me. Infact the day i am gonna get crucified. I have a meeting with my supervisor and till this point i don't have any tangible results that could substantially speak of my work for the past few weeks. Hope everything goes well. Will update on what happened tomorrow.

Type-2 Fuzzy logic

Its been a long time now since my last post. I wouldn't say i was busy. As a matter of fact i had lots of time, much more than what i used to have but out of laziness i did not update it. Anyways back to the blogging session, I was thinking about what to write out here. Even though i had written a blog article on fuzzy logic, i thought this topic should be more emphasized upon. The type-1 fuzzy logic is a very primitive type with very less features available in them. Sorry for having assumed that every one knows what type-1 means. When an input is fuzzified using two-dimensions only, it is called as type-1. When another dimension is added to this to increase its fuzzy nature, then it becomes type-2. I really wonder how people think in these ways and come up such beautiful ideas. I would say i am not even 1% of these great people who have invented such methods. But still i am doing my PhD.....Hope i would be able to come up with such an idea that would be appreciated by someone some
