 dynamics. Because of this, hybrid systems cannot be fully analyzed using only
 tools from continuous or discrete methods. Today, hybrid control systems are
-unable to completely verified.
+unable to be completely verified, that is to say we do not currently have ways
+of being building hybrid control systems that we can be certain meet high level
+strategic objectives, or who's behavior is totally understood.
 
+The ambiguity on hybrid system behavior is problematic when one of the most
+useful cases of hybrid system control is for improved autonomy of critical
+systems. Nuclear power is a salient example. For a nuclear reactor during
+start-up, every mode of power from initially cold-start, to controlled core
+heating, and eventually  full operating power is well understood dynamically.
+For each of these modes, significant portions of the control are optimized using
+automated controllers for each stage. The problem that remains for human
+operators is choosing when to switch from control law to the next, and ensuring
+that the proper conditions are met to do so--but these conditions are also
+clearly defined in regulation and operating procedures a priori.
+
+We can use the fact that these transition points are well understood in
+combination with formal methods to synthesize the discrete part of a hybrid
+system. From that point, we can have a robust chain of proof that our discrete
+jumps will happen only at the correct times. Once that is established, we can
+use reachability analysis and traditional control theory to ensure that each
+operation 'mode' satisfies liveness, stability, or performance requirements.
+With the combination of these two methods, we can be sure of correct behavior
+switching between modes, and that strategic goals remain met while transitioning
+from one mode switch to the next.
+
+If this research is successful, we will be able to do the following:
+
+\begin{enumerate}
+
+  \item
+    \textbf{Formalize} mode switching requirements as logical statements that
+    can then be translated into a controller implementation. This piece will
+    address the correct-by-construction generation of the mode switching
+    controller.
+
+  \item 
+    \textbf{Categorize} different continuous modes by their strategic relevance.
+    Certain modes exist as control laws from one mode to the next, such as a
+    controlled heating rate on reactor start-up before reaching operational
+    conditions. Other modes exist as stable regions, such as full-power
+    operation. 
+
+  \item
+    \textbf{Verify} continuous modes and accompanying continuous control laws
+    satisfy strategic requirements. This can be done with reachability analysis,
+    and ensuring that each mode transition as allowed from the requirements
+    synthesis squares up against the reachability analysis and the continuous
+    dynamics.
+
+  \item
+    \textbf{Prove} that a given hybrid system achieves strategic goals across
+    hybrid control modes. By seperately formalizing and analyzing continuous
+    dyanmics and discrete dynamics, we can come back to say the whole hybrid
+    system has met a strong guarantee of requirement adherence.

+# Tuesday, September 02, 2025 - 10:51 PM
+
+Today was somewhat of a full day, and an even fuller head of
+thoughts. But, that's what you're for dear journal.
+
+I started today off feeling anxious as all hell. This might
+seem silly further in the future, but I think a lot of it
+comes down to feelings about a girl. For future me who may
+not remember well, there's this girl Claire, who you talked
+to on the Benedum patio. There was a bouncy house, for
+whatever fucking reason, and you were smiling politely
+watching some *adults* enjoy the random bouncy house. It was
+a good moment. She noticed, and we struck up a conversation.
+
+She was cool. Claire is a transfer student from Juniata
+college and is now technically a sophomore mechanical
+engineering student, though she'll tell you she's more of a
+junior. Good for her to make that switch--I'm sure that will
+pay off in dividends later. She is interested in
+prosthetics, and you recommended Humotech as a possible spot
+to land an internship next summer. She asked about our
+thesis, and how we like grad school. I'm pretty sure I gave
+an answer somewhere in the middle that I like it a lot but
+it's certainly a challenge. She had to go to class (MEMS
+0024, lol), and I totally fumbled and did not get her
+number. She was clearly interested.
+
+A couple days later, I saw her again on the patio when
+Andrew and I were going to eat lunch. We waved and exchanged
+smiles, but I didn't talk to her other than that. I regret
+that. I feel like I felt weird if I would've left Andrew
+alone while I did that, which probably does have some merit,
+but I also feel like there's an age gap problem. I'm 24,
+going on 25, and she's 20 (maybe close to 21?). Now that I'm
+writing this, I don't feel like it should be an issue
+really, especially if there's a vibe and they (not
+necessarily Claire) are mature enough. I should've said hi
+and been more deliberate. 
+
+Things took a turn when I found her profile on Tinder.
+Before, I thought she was cute and nice, but her first
+picture on her profile at the time is her in a pink floral
+two piece swimsuit, and holy moly she is hot. I have to
+admit I was taken pretty down hard by lust at that point.
+She, at the time of this writing, has not liked me back.
+With a profile like that though I'm sure she's getting
+plenty of attention and I might be lost in the stack. I'm
+not too pressed about it. 
+
+Knowing that her class was today (Tuesday) though, I thought
+I'd sit out on the patio in case we bumped into each other.
+I did see her, but either she did not see me, or
+purposefully avoided me while she was headed into class. I
+think she was just busy. I'll try again next week perhaps
+unless I see her sooner? Who's to say. Not a priority.
+
+I had therapy today. That went okay, I guess. We talked
+about this feeling of feeling disconnected that I've had
+recently. I have felt somewhat alone even while around
+others, and a bit less like myself. Kind of like I have less
+control over what I say or do. I would really like to get a
+handle on that. This journal should help. Rachel also
+recommened checking out a self-compassion test and to give
+myself some credit that things are good, and it's okay to be
+feeling weird. It's a big transition from what I was living.
+She also pointed at trauma... is this a trauma response? Am
+I waiting for a shoe to drop?
+
+One thing we talked about is why am I not able to bring
+myself the happiness I would expect to get from having a
+partner? Am I seeking someone because I genuinely want a
+relationship or because I feel like I need someone else or
+am bored? I think it might be the latter, and that it's not
+a good time for me to get serious right now. I don't want to
+keep my head under the sand either, but it might be a good
+idea to relax some. I need to be happy on my own before I
+can bring that happiness to the table with someone else. But
+we'll get there.
+
+Lewie is feeling rough with leg pains again. Amber and I
+were supposed to meet up this weekend to hang out at the dog
+park but that has been postponed a couple of weeks. I really
+hope he feels better soon, I feel bad for the puppo. I
+thought I saw a little limp on the webcam last week, but he
+immediately walked it off. Maybe that concrete isn't
+helping. Poor thing.
+
+Then, I went to Ngoc's grandma's wake. She was 83 when she
+died. It was somber, and honestly really hard to be there.
+Kim was particularly upset. Their family was very kind, but
+it reminded me of the disbelief that I had when my mom died.
+I remember the wake being very strange. I flitted around the
+room talking to different people almost as if to entertain.
+Like nothing was really that wrong to begin with. Then, when
+the pawl bearers brought the casket out, there was a
+realization that overtook me completely. I could see that
+for some of her family, they hadn't hit that realization
+yet. 
+
+I drove back to school after that and hung out in Matt's lab
+for a while. I tried to write some goals and outcomes, but
+didn't make any progress. It was nice to be around friends,
+though. Then, I gave David a ride up to the VA hospital
+where his car was parked.
+
+I thought I noticed Eliana shooting looks at me. I followed
+her on instagram, I guess we'll see where things go.
+
+Tomorrow I'll see Devyn and Erik! I'm very excited for that.
+We're getting dinner at Totopo and perhaps drinks at
+Hitchhiker. Devyn is interviewing at Aerotech for a new job.
+Good for him. It'll be nice to see Erik too.
+
+That's pretty much it. I listened to some Matt Maltese this
+afternoon and that made me feel a bit better. Now that it's
+after midnight, I can't complain and feel more neutral than
+anything. I'm excited to ride my bike in to school tomorrow.
