I beat my depression after 13 years, and started to gain not only my weight back, but my self love as well. I’ve never been so happy, and I’ve never been so fine. Happiness looks so good on me.
I know she isn’t on anymore, but I wish I could tell artistiquesoul how adorable I think she is. Happiness is a beautiful look.
Lol. I’m still on. I just changed my name to @charicemonet :) Thank you though.
I might’ve just fell for somone

Transatomic Power reduced their claims of nuclear fuel efficiency
http://ift.tt/2aB80ot
In a white paper published in March 2014, Transatomic Power proclaimed its molten salt reactor "can generate up to 75 times more electricity per ton of mined uranium than a light-water reactor."
In a paper on its site dated November 2016, the company downgraded “75 times” to "more than twice." In addition, it now specifies that the design “does not reduce existing stockpiles of spent nuclear fuel,” or use them as its fuel source. The promise of recycling nuclear waste, which poses tricky storage and proliferation challenges, was a key initial promise of the company that captured considerable attention.
Oak Ridge National Labs confirmed the Transatomic power work and designs

Deep ocean GPS would revolutionize submarine and naval warfare
http://ift.tt/2aB80ot
DARPA is creating a GPS-like technology that works in the deep ocean called Positioning System for Deep Ocean Navigation, or POSYDON.
The Global Positioning System (GPS) is the predominant means of obtaining positioning, navigation, and timing (PNT) information for both military and civilian systems and applications. However, the radio frequency basis for GPS also means that its signals cannot penetrate seawater, and thus undersea GPS is effectively denied. The Positioning System for Deep Ocean Navigation (POSYDON) program aims to develop an undersea system that provides omnipresent, robust positioning across ocean basins. By ranging to a small number of long-range acoustic sources, an undersea platform would be able to obtain continuous, accurate positioning without surfacing for a GPS fix. Phase I of the program focuses on accurately modeling the signal propagation channel, and Phase II focuses on developing the signal waveform. A complete positioning system is scheduled to be demonstrated in Phase III.
DARPA selected BAE Systems to develop POSYDON
DARPA envisions that the POSYDON program will distribute a small number of acoustic sources, analogous to GPS satellites, around an ocean basin.
Underwater acoustic signal propagation channels present a number of challenges:
• Time-varying multipath propagation and multipath delay
• Doppler spread due to platform motion relative to the acoustic source(s) and ocean environment
• Bandwidth-limited signals
• Convergence zones
• Tomographic calibration of a region as a function of time/environmental variability
There are some GPS radio systems that can work in shallow waters, but DARPA wants to go into the deep ocean with submarine drones. Submarine navigation is one of the most complex and dangerous ventures in the military because, to get a precise location on one, the vessel has to eventually emerge from the water to catch a radio signal. Even access to a GPS can be blocked by enemy jamming.
Currently, submarines are outfitted with a “very large and very expensive inertial measurement unit,”Niedzwiecki. says. It basically remembers the submarines last known location and keeps track of its diving depth and forward movement. This, of course, is not the nearly as precise as a GPS system.
Drone subs operating under POSYDON could locate underwater mines, track enemy subs and perform other critical tasks larger manned submarines cannot, according to The National Interest:
* Number of small drones could send out an acoustic ping and then analyze
* Drone swarms update ships and submarines

Future US Navy plans are all about doubling or tripling the missiles they can shoot and how many missiles they can defend against
http://ift.tt/2aB80ot
In World War II, the U.S. Navy made extensive use of small aircraft carriers, ranging from very small carriers escorting convoys (CVEs) to light aircraft carriers (CVLs) that were essentially downsized models of the iconic big carriers (CVs).
CVLs could handle post-WWII jets. However, the Navy concluded super carriers made more sense strategically and economically. Nuclear-powered super carriers (CVNs) could carry a wing of multi-mission, high-performance combat aircraft and pack an array of defensive weapons. They could remain at sea for months.
Smaller carriers currently are used to carry harrier jump jets and/or helicopters.
China has been a leader in long-range anti-carrier missiles. China has deployed the DF-21D anti-ship ballistic missile (ASBM). The DF-21D is clearly designed to target and sink the US Navy large nuclear aircraft carriers.
The US US Navy officers is worried that just having big carriers is putting too many eggs in too few baskets.
The new plans are for two or three small carriers to go with the large carriers. There would be the addition of drones and F35 jets put onto the small carriers and also stronger drones onto every ship.

MITRE's future navy plan has a concept called the "Magazine Ship." The MGX would carry up to 4 railguns, 1,000 missile silos, or 96 Pershing-III intermediate range ballistic—or some mix.
Three new navy plans all are focused on more ships, with more missiles, more drones and more planes. Lethality is increased with more missiles, more planes and more drones. The total number of weapons are increased and they are put on more ships.
Adding three small carriers would double the number of planes and drones in a carrier group.
The current missile destroyers are armed with about 90-100 missiles.
A carrier strike group (CSG) is an operational formation of the United States Navy. It is composed of roughly 7,500 personnel, an aircraft carrier, at least one cruiser, a destroyer squadron of at least two destroyers and/or frigates, and a carrier air wing of 65 to 70 aircraft.
MGX ships could bring 3 to 5 times the number of missiles in a carrier group.
Adding railguns and lasers if about being to defend against more enemy missiles. Drones can shoot missiles and anti-missiles.
Each of the 100 or so page plans for the future US Navy boil down to being able to shoot a lot more missiles and being able to defend against more missiles.
