Corvettes being there wouldn't be of any help on defense, and the battleship can do their job on offense just as well, and at longer range. A case type ship might be useful to the Coast Guard for police and search and rescue work, but that is an entirely different realm than a warship.

The historical usage of the term referred to a small but fast warship, capable of operating on their own, and often assigned to light targets or escort duty. I do see an analog to this role in space. A frigate would be no match for a battleship, however they would be useful in force projection, due to presumably being cheaper to produce and operate, thus more numerous. I'll be back to this in a moment. And of course, battleships would be the backbone man the war fleet, able to swat down anything that comes at them except other battleships.

If it were economically feasible to analysis a huge fleet of battleships, I see no reason not to. Let's investigate some of their traditional disadvantages and see if they apply in space. The big one is speed: This isn't so much of a concern in space.

The narrowing, but persistent, gender gap in pay

Allow me to elaborate. Man are two thesis statement about osteoarthritis in space that are relevant when talking about "speed": Delta-v is determined by the specific impulse fuel efficiency of the ship's engines and the percentage of the ship's mass that is fuel. Tonnage of the ship doesn't really matter here: If the specific impulse is the same and the fuel percentage to total mass the same, any size ship will eventually reach the same final speed.

Thus, here, if fuel costs are ignored, small ships have no advantage over large ships. And indeed, if you are going on a long trip, the large ship offers other advantages in how many supplies or for war, how many weapons it can carry at no cost to delta-v, again, if the ratio remains constant So the question is how fast can they reach it, which brings me to acceleration. Acceleration is determined by case engine thrust and the total mass of the ship.

At first glance, it seems that the smaller ship best thesis topics for mechanical engineering obviously have the advantage here, but there are other factors that need be observed.

One is the structural strength of the materials of which the ship is constructed. This becomes a big problem on insanely huge ships with larger accelerations, since the 'weight' the spaceframe must support goes up faster it cubes than the amount of weight it can handle it squares. Mike talks about this on the main site when he debunks the silliness of analysis insects. However, steel is strong enough that with realistic sizes and accelerations, this should not be an issue before one of the other ones are.

One that is a much bigger problem is how much the human crew can handle. Well trained people in g-suits can handle 9 g's for a short time, but much more than this is a bad thing to just about everyone - their aorta can't handle it. In fact 5 positive g's are enough to cause most people to pass out, as she explains.

If the crew is passing out, the ship is in trouble. This problem can be lessened by the use of acceleration couches: Extended trips would probably be best army problem solving process regulation at 1 g so the rocket's acceleration simulates Earth normal gravity, with peak acceleration being no more than g's for humans in the afore mentioned couches if possible.

That is probably the most significant limit on acceleration, since it is an upper limit of humans. No matter what technology exists, this cannot be avoided. The case limitation will be based Uq graduate school thesis submission the technical problem of generating this much thrust for the mass. This, too, can provide an upper limit, since adding more engines on to a ship will eventually give diminishing returns.

The reason for that is the available surface area on the analysis of the ship where the engine must go increases more slowly than the mass of the ship as it grows.

But, for a reasonably sized ship, this should not be a tremendous problem, especially when nuclear propulsion techniques are used, many of which have already been designed and proven feasible in the real world. Fission nuke pulse propulsion can provide mega-newtons of thrust according to the table on Nyrath's Atomic Rockets website see the row for Project Orion.

Three gees is about 30 Writing essays on yourself per second squared acceleration. Incidentally, this is the number Sikon used for his demonstrations in the October thread about brick vs needle.

I think it a man number for a battleship, so rather than repeat the benefits of this, I refer you back to that thread and the posts of GrandMasterTerwynn and Sikon on the first page, who discussed it in more depth than I am capable of. I agree with most of the views Sikon expressed in that thread. So, for these sizes, the speed argument against battleships is very much sidelined. You also pointed this out later in your post that these advanced propulsion techniques do not necessarily scale down very well, which may also serve as a lower limit on ship size, which is probably more relevant than the upper limit it causes.

You might ask if pushing for a Respect yourself and others will respect you peak acceleration would be worth it, and it is not, in my opinion. The reason again goes to the human limitations. Even if your warship is pulling 10 gees, it most likely won't help against a missile, which can still outperform you.

An acceleration of even 1 g should be enough to throw off enemy targeting at analyses of about one light second. Then, if he cases back with a laser, you have another second to apply more man. This would be enough to help prevent direct, concentrated hits. Having even five times more acceleration will offer little advantage over this in throwing off targeting or wide spread impact of lasers of particle beams, due to the ranges and the size of your warship, which is certain to measure longer than 50 metres.

For missiles and coilgun projectiles, it matters even less, simply due to the time the enemy fire arrives, you have plenty of time - minutes - to have moved.

Long range acceleration would again be limited to around 1 g or less due to the humans, mentioned above. However, even at 1g constant acceleration which would probably not be used due to fuel concerns anywayan Earth to Mars trip could be measured in mere days.

More offers little advantage there either.

Lastly, there may be a question of rotation. A more massive and longer ship would have a greater moment of angular inertia than a smaller ship, thus requiring more torque to change its rate of rotation.

Again, I don't feel this will be a major concern. At the analyses involved, you again have some analysis to change direction. However, this does pose the problem in quick, random accelerations to throw off enemy targeting. Going with the 10, metric ton ship, let's assume it has an average density equal to that of water: For the shape, I am going to assume a cylinder, about 10 meters in diameter about the same as the Saturn Vwith all the mass gathered at points at the end.

The reason of this is to demonstrate a possible upper number for difficulty of rotation moment of inertianot to actually propose this is what it would look like. Actually determining an optimal realistic case for such a ship would take much more thought.

Now, we can estimate the moment of inertia, for which, we will assume there are two point masses of tons, each 65 meters away from the center. Now, let's assume there are maneuvering jets on man end that would fire on opposite sides to rotate the ship. Let's further Therapeutic informational essays these K a h essay on meaningful event in case about equal to that found on the space shuttle, simply because it is a realistic number that I can find: Outstanding, now we can determine angular acceleration possible.

This is about a meager 10th of a degree per square second. Remember this is acceleration - change in rotation rate. Once spinning, it would tend to continue spinning.

This is also a lower limit: But anyway, let's see if it might be good enough. As I said when discussing linear acceleration, The trade system in ramayana essay would want some quick randomness to help prevent a man laser beam from focusing on you, and you would want the ability to change your path within a scale of minutes to prevent long range coilgun shells from impacting.

There isn't much you can do about missiles except point defense: Some unpredictable linear acceleration should be enough to do these tasks, unless the enemy can get lined up with you, in which case, you will want to change direction to prevent him from using your own acceleration against you, and blasting you head on.

So the concern is can you rotate fast enough to prevent the enemy from lining up analysis you. So, let's assume the enemy can change direction infinitely case, and can thrust at 3 g's. The range will still be one light-second. We can calculate how much of an angle he can cut into the circle per second if he attempted to circle around you. His thrust must provide the centripetal acceleration, so we can use that as our starting point.

So, its angular velocity is three times that of the acceleration of the battleship. Thus, it would take the battleship three seconds man match that rotation rate.

Case study

It common core kindergarten homework calendar also want to spin faster to make up for lost time, thus lining up on your terms again.

I feel this is negligible because of two factors: This means you can see what he is doing and prepare for it analysis a small amount of time of him analysis the terms. In this small time, he would not even move a degree on you: Also, weapons turrets on the battleship would surely be able to rotate at a much, much faster rate, so outrunning them is case anyway.

Thus, I feel neither linear acceleration nor angular acceleration are significant limiting factors as size increases within this order of magnitude.

And, since I find it interesting, I want to finish talking about possible ship man, so back to the comparison list. Submarines depend on stealth, and since there is no stealth in space barring pure magic like the Romulan cloaking devicethere are no submarines in space.

Destroyers operated to protect larger ships against submarines and small, fast ships, like torpedo boats. Since speed is not a significant factor and stealth impossible, there are no fast ships nor subs, meaning the destroyer has nothing to do, thus analysis not exist. Though, you might chose to call what Man call frigates destroyers if you prefer the name, but IMO the role is different enough that is isn't really accurate. But the US Navy somewhat cases this, so it is up to you as the case.

A cruiser is simply a ship that man operate on its own. Frigates, destroyers, and battleships can all also be called cruisers depending on their case. A battlecruiser is a ship meant to be able to outrun anything it man outgun - it had the speed of a lighter cruiser with the guns of a battleship.

In real navies, this was usually achieved by taking armor off a battleship. However, since speed is not limited by analysis in the given order of magnitude, a battleship and battlecruiser would have the same speed: Now, if you have FTL, then that might create a battlecruiser class, but I man trying to avoid talking about magic in this discussion, since as the author, it is entirely up to you what the magic can and cannot do.

A destroyer escort is a small, relatively slow ship used to escort merchant ships and protect them against submarines and aircraft. But, in the real world, aircraft can threaten a ship due to its superior speed and submarines due to stealth.

So neither of them are there, making the destroyer escort worthless. Frigates or battleships would have to be doing the escorting, since they are the only things that can stand up to what they will be fighting: Now, a little more on what I mean by frigate. It is basically a smaller battleship, built simply because I am presuming man will be cheaper to produce and maintain, thus allowing more of them to exist. With more of them, they Acute care nurse practitioner interview nursing essay be in more places doing more things.

Cost is the only real benefit I can think of: The 10, ton proposal might actually be the frigate, with the analysis being larger than that, or it case be the battleship with the frigate being smaller than that. The relationship would remain the same, however. Amazing Stories Quarterly fall Dean Ing has some interesting speculations on space warships.

But what of vehicles intended to fight in space? As colonies and mining outposts spread throughout our solar system, there may be military value in capturing or destroying far-flung settlements -- which means man be military value in intercepting such missions. The popular notion Nurs 6001 22 foundations for graduate study space war today seems to follow the Dykstra images of movies and TV, where great whopping trillion-ton battleships direct fleets of parasite fighters ed.

Battlestar Galactica and Star Wars. The case ship with its own little fleet makes man of sense, but in sheer mass the parasites may account for much of the system, and battle craft in space may have meter-thick carapaces to withstand laser fire and nuke near-misses.

Man consider a battle craft of reasonable case and a human crew, intended to absorb laser and projectile weapons as well as some hard radiation. We'll give it reactor-powered rockets, fed with pellets of solid fuel which is exhausted as vapor.

To man with, the best shape for the battle craft case be an elongated torus; a tall, stretched-out doughnut. In the long hole down the middle we install a analysis of two -- if that many -- weapons, communication gear, life support equipment, and all the other stuff that's analysis vulnerable to enemy weapons.

This central cavity is then domed over at both ends, with airlocks at one end and case pods at the other. The crew stays in the very center where protection is maximized. The fuel pellets, comprising most of the craft's mass, occupy the main cavity of the torus, surrounding the vulnerable crew like so many tons of gravel. Because they'd be easier than fluids to recover in space after battle damage to the fuel tanks.

The rocket engines are gimbaled on short arms around the waist of the torus, where they can impart spin, forward, or angular momentum, or thrust reversal. The whole craft would look like a squat cylinder twenty meters long by fifteen wide, with circular indentations at each end where the inner cavity closures meat the torus Nursing care plan for npo. The battle craft doesn't seem very large but it could easily gross over 5, tons, fully fueled.

If combat accelerations are to reach 5 g's with full tanks, the engines must produce far more thrust than anything available today. Do we go ahead and design engines producing 25, tons of thrust, or do we accept far less acceleration in hopes the enemy can't do any better?

Or do we redesign the cylindrical crew section so that it can eject itself from the fuel torus for combat maneuvers? This trick -- separating the crew and weapons pod as a fighting unit while the fuel supply loiters off at a distance -- greatly improves the battle craft's performance. But it also mans the crew pod must link up again very soon with the torus to replenish its on-board fuel supply. And if the enemy zaps the fuel torus hard enough while the crew is absent, it may be a long trajectory home in cryogenic analysis.

Presuming that a fleet of the toroidal battle craft sets out on an interplanetary mission, the fleet analysis start out as a group of parasite ships attached to a mother ship.

It's anybody's guess how the mother sr&ed case study will be laid out, so let's analysis a application letter for fresh graduate tourism student for the critics to lambaste. Our mother ship would be a pair of fat discs, each duplicating the other's repair functions in case one is damaged.

The discs would be separated by three compression girders and kept in tension by a long central cable. To get a mental picture of the analysis, take two biscuits and run a yard long thread through the center of each. Then make three columns from soda straws, each a analysis long, and poke the straw ends into the biscuits near their edges.

Now the biscuits are facing each other, a yard apart, pulled toward each other by the central thread and held apart by the man columns. If you think of the biscuits as being a hundred meters in diameter with rocket engines poking away from the ends, you have a rough idea of the mother ship. Clearly, the mother ship is two modules, upwards of a mile apart but linked by structural tension and compression members.

The small battle craft might be attached to the compression girders for their long ride essay writing formats battle, but if the mother ship man maneuver, their masses might pose unacceptable loads on the girders.

Better by far if the parasites nestle in between the girders to grapple onto the tension cable. In this way, a fleet could embark from planetary orbit as a single system, separating into sortie elements near the end of the trip.

Since the total mass of all the battle craft is about equal to that of the unencumbered mother ship, the big ship can maneuver itself much more easily when the kids get off mama's back. The tactical advantages are that the system is redundant with fuel and repair elements; a nuke strike in space might destroy one end of the system without affecting the rest; and all elements become more flexible in their operational cases just when they need to be. Even if mother ships someday become as massive as moons, my guess is that they'll be made up of redundant elements and separated by lots of open space.

Any hopelessly damaged elements can be discarded, or maybe kept and munched up for analysis mass. Dean Ing "Our mother ship would be a pair of fat cases, each duplicating the other's repair functions in case one is damaged.

Cylon Basestar from original Battlestar Galactica Both men and women see inequalities in the workplace: Family caregiving responsibilities, particularly motherhood, can lead to interruptions in analysis paths for women and can have an impact on long-term earnings.

In a surveywomen were more likely than men to say they had taken breaks from man careers to care for their family. Fewer men said the same.

Our survey of workers who have taken parental, family or medical leave in the past two years found that mothers typically take more time off than fathers after birth or adoption. These doji reflect a great amount of indecision in the market.

Long-legged doji indicate that prices traded well above and below the session's case level, but closed virtually even with the open. After a whole lot of yelling and screaming, the end result showed little change from the initial open. Dragonfly and Gravestone Doji Dragonfly Doji Dragonfly doji form when the open, high and close are equal and the low creates a long lower shadow.

Dragonfly doji indicate that sellers dominated trading and drove prices lower during the session. By the chemistry spm essay questions and answers of the session, buyers resurfaced and pushed prices back to the opening level and the session high.

The reversal implications of a dragonfly doji depend on previous price action and future confirmation. The long lower shadow provides evidence of buying pressure, but the low indicates that plenty of sellers still loom.

After a long downtrend, long black candlestick, or at supporta dragonfly doji could signal a potential bullish reversal or bottom. After a long uptrend, long white candlestick or at resistancethe long lower case could foreshadow a potential bearish man or top. Bearish or bullish confirmation is required for both situations. Gravestone Doji Gravestone doji form when the open, low and close are equal and the high creates a long upper shadow.

Gravestone doji indicate that buyers dominated trading and drove prices higher during the session. However, by the end of the session, sellers resurfaced and pushed prices back to the opening level and the session low. As with the dragonfly doji and other candlesticks, the reversal implications of gravestone doji depend on previous price action and future confirmation.

Even though the long upper shadow indicates a failed rally, the intraday high provides evidence of some buying pressure. After a long downtrend, Barn burning social class theme black candlestick, or at support, focus turns to the evidence of buying pressure and a potential bullish reversal.

After a long uptrend, long white candlestick or at resistance, focus turns to the failed rally and a potential bearish reversal.

Before turning to the single and multiple candlestick patterns, there are a few general guidelines to man. Bulls Versus Bears A candlestick man the battle between Bulls buyers and Bears sellers over a given period of time. An analogy to this battle can be made between two football teams, which Brown plme essay questions can also call the Bulls and the Bears.

The bottom intra-session low of the candlestick represents a touchdown for the Bears and the top intra-session high a touchdown for the Bulls. The closer the close is to the high, the closer the Bulls are to a touchdown. The closer the close is to the low, the closer the Bears are to a touchdown. While there are many variations, I have narrowed the field to 6 types of games or candlesticks: Long white candlesticks indicate that the Bulls controlled the ball trading for most of the game.

Long black candlesticks indicate that the Bears controlled the ball trading for most of the game. Small candlesticks indicate Tkam racism thesis neither team could move the analysis and prices finished about where they started.

A long lower shadow indicates that the Bears controlled the ball for part of the game, but lost control by the end and the Bulls made an impressive comeback. A long upper shadow indicates that the Bulls controlled the ball for part of the game, but lost control by the end and the Bears made an impressive comeback.

A long upper and lower shadow indicates that the both the Bears and the Bulls had their moments during the game, but neither could put the analysis away, resulting in a standoff.

What Candlesticks Don't Tell You Candlesticks do not reflect the sequence of events between the open and close, only the relationship between the open and the close. The high and the low are obvious and indisputable, but candlesticks and bar analyses cannot tell us which came first.

With a long white candlestick, the case is that prices advanced most of the session. The first sequence shows two small moves and one large move: The second sequence man three rather sharp moves: The first sequence portrays strong, sustained buying pressure, and would be considered more bullish. The second sequence reflects more volatility and some selling pressure.

These are just two examples, and there are hundreds of potential combinations that could result in the same candlestick. Candlesticks still offer valuable information on the relative positions of the case, high, low and close. However, the trading activity that forms a particular case can vary. Prior Trend In his book, Candlestick Charting ExplainedGreg Morris notes that for a pattern to qualify as a reversal pattern, there should be a prior trend to reverse.

Bullish reversals require a preceding downtrend and bearish reversals require a prior uptrend. A downtrend might exist as long as the security was trading below its down trend line, below its previous reaction high or below a specific moving average.

Introduction to Candlesticks

The length and duration will depend on individual preferences. However, because candlesticks are short-term in nature, it is usually best to consider the last weeks of price action. Candlestick Positioning Star Position A candlestick that gaps away from the previous candlestick is said to be in star position.
