United States nuclear surety

For more information, see United States nuclear weapons. Surety encompasses design features, material, personnel, and procedures.”[1]

Nuclear surety also extends to the nuclear research and production infrastructure, to military and civilian nuclear power, to diversion of commercial and medical radioactives and as part of protective measures against nuclear terrorism and radiological weapons.

A number of these techniques were shared with other nuclear powers, in the interest of avoiding accidental war. Not all were accepted; not all were shared. Since the end of the Cold War, surety, in the broadest sense, has included efforts to bring surplus experts and critical nuclear material, in the former Soviet Union, outside the reach of non national groups and rogue nations.

Certain technologies are potentially as decisive or destructive as nuclear weapons, especially the largely obsolete small tactical nuclear weapons, which have largely been replaced with precision guided munitions. Secretary of Defense, or their successors. Eventually, Eisenhower, a former general, took policy control and started the machinery that produced the Single Integrated Operational Plan, first published as a classified document in 1962.

Two person control continues through all command and control levels, from high military levels down to weapon maintenance and firing crews. Unknown until well after they arrived, and were not under special guard, they carried live nuclear warheads.

Resulting investigations contributed to the firing of the Secretary of the Air Force, the Chief of Staff of the Air Force, and a number of senior commanders. Over 70 people were disciplined and there were major reviews and changes in procedures.

Weapons themselves have a growing number of internal and colocated safeguards against accident and misuse. The graphic shows a schematic of a weapon,

which is surrounded by a mechanically and electrically robust exclusion region, into which flow several unique signals (UQS) recognized by designated Strong Links, probably through a cryptographic mechanism. Certain weapons have also had mechanical safing mechanisms, such as a neutron absorbing wire that extended into the pit until arming, or, in the somewhat dubious case of the British Violet Club, a bagful of ball bearings.

These unique and operational signals arm the strong link switches within the weak link strong link safeguard of the firing set, which are probably part of the high voltage system that charges the capacitors that power the multiple detonators. If any predesignated weak link condition comes into being, such as crushing or puncture of the exclusion barrier, fire surrounding it, or a crash if the weapon is fuzed for airburst, the weak link opens and breaks the firing circuits. For certain conditions, such as crashes, a more complex weak link sensor may initiate a self destruct for the weapon, one which will not produce a nuclear yield.

An emergency destruct command may be used to actuate the weak link, a small demolition charge, or some mechanical technique that makes the bomb unusuable without complete factory overhaul.

Fission device implosion systems must have detonators triggered, with precise timing, at multiple points for the implosion to occur. The one point safe criterion requires a one in a billion chance that a single detonation would produce a nuclear yield of greater than two kilograms. ensures that weapons that have been distributed to operational units, or are in ready storage, will function if needed. Minimally, this includes ensuring that regular and preplanned maintenance is performed. Next, it verifies that components of the weapons will perform as needed.

Nuclear weapons have a number of components that have to be replaced periodically, starting with specialized batteries, and radioactive materials, especially tritium,

which decay to a point of uselessness. High explosive components have been found to lose necessary mechanical properties over time.

Unit Dose and Blister Packaging

Unit Dose and Blister Packaging

My son came home and informed me of a field trip he was going on to the unit dose packaging and blister packaging plant that is in town. I was thrilled and signed up to go as a parent volunteer. I was so curious to how they put these pack together with a machine system and wanted to see for myself.

As I waited for the day of the field trip, I researched all about the unit dose packaging machines that we would be shown on the tour. They were fascinating to me just reading about them, and I would get to see how the whole system works soon. Without any human labor, these machines packed an allergy medicine into little unit does packages. It was exciting to me when I thought about how we would see a plain piece of plastic and a piece of foil turned into a blister package by a big machine.

When we finally made it to the factory,
Unit Dose and Blister Packaging
the kids and myself were so excited. First the tour began with some medical professionals teaching us about the allergy medicine that would go into the unit dose packaging system. At the factory they were doing stock blister packaging which is a bunch of packs being packaged at once for a huge shipment. This makes it easier to ship and purchase the blister packs. This certain allergy medication will be sent out to pharmacies and grocery stores so that consumers can purchase them over the counter. The unit dose packaging machine will also make little sample packages.

When the medical professionals were done with their little speech about the allergy medication, they handed out empty unit dose packages to the children. This let them see and feel what blister packaging is like and have something to take home with them. All the kids punched through the foil and could see where the pill would have been in the unit dose packaging container. The children were able to see how important unit dose packaging and blister packaging is to the pharmacies and how much we use this type of packaging.

We then moved to a different room where the unit dose packaging and blister packaging machines were and this was the children’s favorite part. It was so fun to watch the plastic sheets feed into the machine. Then we watched long pieces of foil go into the machine. The foil pieces is the backing and the label for the medication. We watched as the allergy pills were dropped into the plastic cases in their little slots. Then the finished blister package slid out of the other side of the machine all finished. The packs were then placed into a box to be shipped to it’s proper destination and sold to consumers. The process was very cool to watch with the young children.

Watching the unit dose packaging and blister packaging machines suck in plastic and spit out a finished blister pack was fascinating. The machines are very fast and efficient, not needing any humans to do any work. The children loved all the parts moving and thought the machine system looked like a robot. They also thought it was very cool that the machine was working on its own without anybody doing anything but turning the machine on.

Understanding Marketing Environment

Understanding Marketing Environment

It is very important for any business to scan and analyze their marketing environment by continuously monitoring what is going on in the marketing environment. Marketing decision makers must collect, analyze and diagnose information about the environment. These actions of marketing decisions are explained under:Any person venturing into any kind of business must be aware of his/her business environment. It is therefore very important for business to be positioned and be designed in a way that its image is in distinctive place in the market. It must thrive to provide best quality, best service, best value, lowest price and more advanced technology. When a business understands its environment correctly there is no doubt for it to achieve success and become profitable throughout its running.

SWOT analysis is an overall evaluation of a company’s strengths, weaknesses, opportunities and threats. It involves monitoring the external and internal marketing environment. SWOT analysis assumes that organization will achieve success by maximizing strengths and opportunities and minimizing weaknesses and threats. It is very important for a company to indentify its weaknesses and opportunities as the information provided will help in informing the managers of the company on the various developments in the external and internal environment that have taken place. Also it leads to improved organizational performance and the company can also be in a position to framework its current and future positions.

A SWOT analysis is a procedure for identifying and examining opportunities and strengths, weaknesses and threats facing the business. It gives insight into company’s position in the competitive arena. When carrying out SWOT analysis to determine how you rate against a competitor, the following should be used (Kottler,2002)

Strengths consider your company’s strong points, this should be both from your own and your customers, don’t be modest but be realistic, consider distinct advantages that your company offers; what customers say, do they enjoy doing business with you; is there anything you currently offer that cannot be copied by a competitor now or in future.

Weaknesses evaluate your company weaknesses,

Ultimate Raspberry Pi Home Server

Ultimate Raspberry Pi Home Server

Follow me on twitter here for similar projects; tweet me for any help with this one!In this instructable I hope to teach you key skills involved with setting up and configuring a Linux Server. The knowledge used here can be applied to almost all PC architectures so if you don’t own a Pi (Why not dude?) or it’s tied up in another project, any old or unused PC will work. In more detail the main skills taught will be:

Burning an ISO image to an SD for the Pi Installing an OS Setting up A web server Setting up An SQL instance Deploying a custom cloud network Managing users for the cloud network Setting up a SAMBA File sharing network, which will integrate into an established windows based home or office network Controlling SAMBA users Establishing a static IP whilst using a non static IP internet connection Using Webmin Console to install packages Using Command line terminal to install packages Carrying out basic commands such as rebooting (terminal) Editing system files with Nano terminal based editor Permanently mounting hard drives within the Linux file system table via webmin Understanding the principal of the Port forwarding function on a home router Setting up a web interfaced bit torrent manager Being an overall IT nerd. If you’re interested then carry on reading. If not, give it a try; you may discover a new hobby.

As the above list demonstrates there’s a lot to learn. I definitely feel this is a weekend project. I’ve followed this process several times and it takes a couple of days at least. Its good to take long breaks because your eyes may begin to become strained and you may suddenly become unenthusiastic about the whole thing. This instructable offers functions of many different store purchasable products, such as:

Dedicated Amazon EC2 turnkey serversBelkin routers that offer built in apps Online cloud services such as Google Cloud NAS servers such as this. The server we’ll setup will cost far less than each of these services in the long run and only a fraction of the cost of the combined services. Setting up your own server is not only custom and cheap, its very rewarding. I will be a happy guy if somebody benefits from what this instructable contains or become inspired by what I have done. It took ages to plan and write this instructable. If you learn anything at all or feel this instructable is well written or well documented, please vote for me in the Weekend Projects Contest or the I could make that contest.

I would also like to point out that this is not a comprehensive tutorial on designing a server case. There are details of my case on step 3, however this guide is intended to be a comprehensive software tutorial. So if you get stuck or feel a step isn’t too clear, just let me know and i’ll be happy to help.

A few tips: Because this takes more than one day, don’t just fall asleep and forget what you were planing on doing next. Instead have a pile f post it notes. This way before you ZzZzzzz. you can jot down anything that needs doing during the next session. I had loads. All over the walls, floors, chairs, desks you name it! Okay slight exaggeration, but on a serious note they do help. I did use a full stack. Another tip would be to follow the steps on order. Don’t just think “Hmm I like the sound of my own cloud network lets do that first!” The steps are in such an order that each before is most likely required for the current, if that makes sense. Just stick to the order, it’ll make life easier. A final tip: don’t be limited to what is taught here. Do Think of this as a base for inspiration. Adding more services such as those listed on the turnkey website is easily done using the search APT function within the Webmin Package manager.

Okay, Confused? Then let’s learn.

Caution! This instructable contains 30 steps. There are many aspects involved with planning, and often when people over plan, they quickly lose interest in the actual task.

So, a brief plan is as follows.1 x Raspberry Pi(B model)

1 x External USB 2.5′ HDD(Capacity of your choice, mine is 1TB)

1 x Raspberry Pi Case of your choice(Mine is a cheap 3 laser cut, clear acrylic, self assembly kit from)

2 x Heat sinks for the processor on the Pi(Mine were free with the case)

1 x USB cable for the hard drive

1 x SD Card(8GB or above strongly recommended. Also ensure you copy everything off the card as all data will be deleted.)

There are many available features avaiable to add to a home server, some free, some paid.

I have narrowed down a shortlist of free features that you will be able to add to your home server following the steps in this instructable.

Ultimate Raspberry Pi Configuration Guide

Ultimate Raspberry Pi Configuration Guide

The Raspberry Pi is a great thing: it is real computer, it is cheap ($40), it can interface with electronics, talk to the web and has full HDMI support.However it runs on Linux, which I have a love hate relationship with. I lovethe idea of Linux, but when I start messing around the command line and downloading packages and installing things, I often get lost.I’ve assembled bits and pieces from various online posts and guides into this Instructable, which is what I call the “Ultimate Raspberry Pi Configuration Guide”.What this Instructable does is to set up a wireless Raspberry Pi that allows you to: ssh into from the Terminal window on the Mac (or equivalent on another machine). run wirelessly with a static IP for each SD card. automatically startup, no log in set your the time zone skip the GUI of the Raspberry Pi, which bogs things down and is unnecessary for most tasks minimize any external monitor use, specifically never having to lug a monitor over to where the ethernet router lives clone a “basic settings”SD card so that we can have as many base level installations as we want.Right now, I have 3 Raspberry Pis running in my closet, each with a different purpose: one runs 7 Twitterbots, one is a Git server and one is an experimentation device for electronics. I plan to add more.I wrote this Instructable for someone who has a secure home newtwork. You should have a router that can accept a direct ethernet cable. Get a 2A one if at all possible An 4gb SD card. For most cases, there isn’t a need for anything larger. A USB wifi dongle. It doesn’t matter what the name of the card is.What does matter is that the format is MS DOS (FAT). Format the SD card. It will only take a few seconds.For those of you unfamiliar with using this app, Terminal provides a command line for controlling the underlying Unix operating system on Max OS X.Type in (then press enter):This will list all your mounted drives. You will see something like the image above: a list of drives with different partitions on them. You want to find the information pertaining to your newly formatted SD card. In my case it is /dev/disk1s1. This may be different on your computer.

Ubuntu Linux distribution

Ubuntu Linux distribution

Ubuntu is a Debian based Linux created by Canonical Ltd. It is based on the ideas of the Ubuntu philosophy (“humanity towards others”). Its slogan is “Linux for human beings”, reflecting its focus on ease of use. The latest release is 10.10, codenamed “Maverick Meerkat”. Currently in development is version 11.04, codenamed “Natty Narwhal”. Ubuntu is one of the most widely discussed and possibly widely used Linux distributions, and has received much praise and awards for being an easy to use Operating System. It has also been heavily criticized for some of the practices used in it’s development process, which some state is an attempt to become a “mainstream OS”. [1]A new version of Ubuntu is released every six months, in April and October. The version number is made up of the year and the month that it was released. For example, Ubuntu 7.10 means that it was released in October (from the “10”) 2007 (from the “07”). Each release also has a two word “codename”, which is used both during and after the development process, since many users tend to prefer names rather than numbers. The codename usually consists of an adjective and an animal name. Example, Ubuntu 10.10’s codename is “Karmic Koala”, and many in the Ubuntu/Linux community simply refer to it as “Karmic” or “Ubuntu Karmic”. [2]After a release, development of the next release begins very quickly, to keep up with the 6 month release cycle. Each development cycle has Alpha releases, a Beta release and a Release Candidate before the final release.

The Ubuntu developers take a snapshot of the Debian Unstable repositories. They then focus on ensuring that all of these packages work, and upload newer version of packages when necessary. The release dates are designed so that updated versions of the X Window System and GNOME can be included.

History and releases

4.04 Warty Warthog was the first release of Ubuntu. At this time, the most popular Linux distributions were SUSE, Red Hat and Mandrake (now named Mandriva). Ubuntu began as a fork of Debian Unstable. The difference was that there would be regularly releases every six months, and releases would be based on a snapshot of Debian Unstable, allowing Ubuntu releases to be heavily tested before release. This was in contrast to Debian, where the only heavily tested release is the Stable version, which is criticized for being out of date.

GNOME will be upgraded to version 3.0. Unity will replace Gnome Panel as the default window manager. It includes graphical applications for most tasks, although it does still have a fully operational command line. The default look is the “Human” theme, which uses a caramel color in the active windows and menu items. Support for KDE is also available through installing the “kubuntu desktop” package, or the Kubuntu distribution. Now, however, Ubuntu releases have a graphical installer on the LiveCD, named Ubiquity, meaning that users can try the system before installing it, all on the same CD. There is also an option of a server CD, designed so that no graphical desktop is installed.

Canonical also run a system named “Shipit”; they ship CDs of the latest (and latest LTS) release completely free of charge to users. They are the only major Linux distribution to do this.

Types of Blister Packaging

Types of Blister Packaging

Blister packaging is a way to package medicine, consumer goods, foods, and other types of products. Blister packaging is used in a variety of ways, and has many benefits. Blister Packaging is hard plastic that is pre formed around a product. Think back to a time when you bought a new product. You are excited to open it, and try to do so before you get home, but blister packaging and the hard plastic makes it pretty difficult to open. You find yourself trying to use your teeth, keys, or anything you can find to get it open, however you probably found that it was pretty difficult to do so. Usually with blister packaging you need scissors or some type of razor to get the hard plastic packaging open. Unite dose packaging, the packaging that medicine comes in, however is easy to open. You push through the medication out of the foil side.

Like we mentioned, there are a couple of different types of blister packaging. First, lets talk about blister packaging for consumer goods. If you walk down the toy isle at the store, you will notice most toys are visible through clear plastic, which is blister packaging. This is very beneficial to the product and also to the shopper. The shopper can see the item before they buy it. The reason why this is so important, is because with a lot of items, we want to make sure we are getting what is promised on the box. We don’t want to take it home, to later be disappointed by what was inside a cardboard box. This way you can see the quality first hand before you buy it. Another benefit to having toys and other items,
Types of Blister Packaging
like electronics, food, and everyday items, is protection. Blister packaging helps to protect the item from elements when being shipped to a location and also to help preserve the shelf life of the product.

Another way that blister packaging is used is in the pharmaceutical industry. The pharmaceutical industry packages medicine in blister packaging by different methods. Unit dose packaging is where tablets, lozenges, and medications are packaged each pill individually. There is hard plastic on the front of the pill and to open it, you push the pill through the foil on the back on the package. This kind of blister packaging is easy to open. This type of unit dose packaging and blister packaging, helps the quality of the pill. It doesn’t allow moisture or elements to enter the package, making the quality last longer over time.

Unit dose packaging is becoming more popular in the dental, cosmetic, and veterinary world as well. In a medical office, individual items can be protected by blister packaging to make it easier to sterilize and to use only what they need at once. In the cosmetic industry, a lot of lotions, gels, and samples are being packed in blister packaging. This way, the product is only used once and helps to preserve the product. It also ensures that no product is being wasted, because it already measured.

Recently, blister packaging is becoming more and more popular and effective. Blister packaging has become a standard way of packaging an item, and there are always new innovative breakthroughs and new ideas on how to use blister packaging to protect products.

Turn Your EAGLE Schematic Into a PCB

Turn Your EAGLE Schematic Into a PCB

I guess I should say that we’ll make a PCB DESIGN; making the physical board is a different task, and there are a lot of tutorials on the net (and even some instructables) on making the board after you have the design.

Cadsoft EAGLE generic information:Cadsoft is a German company that is a veritable mecca of software distribution enlightenment. In addition to the reasonably priced professional PCB design packages ($1200), they have freeware, lite, non profit, and other intermediate licenses. Their software runs under windows, linux, and MacOSX. It’s slightly quirky, with a steep (but not too high) learning curve on the front end, but from most reports it is not any more so than other professional CAD packages. They have online support forums that are active from both the company and other users, the package is under current development and gets better with each release. A number of PCB fabricators will accept their CAD files directly. It’s good stuff.

Use it. Propagate it. Buy it when you “go pro.”

Step 1: Starting From the Schematic.

So this is the schematic we have from the Schematic Instructable. Up in the file menu, there’s a “Switch to board” selection. ROUTE is for drawing copper.)VIA create a hole and pad associated with some signal.

I’ll describe the remaining icons toward the end,
Turn Your EAGLE Schematic Into a PCB
and assign them “useful” or “useless.”Step 3: The Untouched PCB Design

This is what the newly created board design will look like. All your components will be in a clump over to the left of the origin, and there will be a frame that marks the allowed size of a board when using the freeware or “Lite” versions of EAGLE (80x100mm). All the component pads will have to be inside that outline when you move them around, although you can cheat a bit and have traces or board outlines that exceed the board size limit. This has the annoying side effect that if you pick up a component from it’s original localtion, you can’t put it back down outside the outline (however, you can use ESC to abort the move, and the component will revert to its original location.) Ok, a few defintions are in orderAll the signals you created in the schematic are currently AIR WIRES; thin yellow lines that are drawn in the shortest possible way, crossing each other as needed. They stay connected to component pins even when you move the component around. The RATSNEST command recomputes and redraws these after you move things around (and, say, make two connected pins closer together than they used to be.)ROUTING a signal consists of turning an airwire into an actual copper trace on some layer(s) of the board, and positioning that trace so that it doesn’t short agains other traces on the same layer of the board. The Freeware version of Eagle only supports a TOP and BOTTOM layer, and as hobbyists we have motivation to try to use only ONE layer. A confusing multitude of layers. Most of the drawing commands have a layer selection pulldown menu that you can use for specifying which layer you want to draw on (exceptions include objects like vias that span multiple layers.)Here are some of the more important layers:Step 5: Move the Components Into the Legal Area

The first thing we want to do is move at least some components into the legal board area where we can work with them. If you have a particularly large board with many components,
Turn Your EAGLE Schematic Into a PCB
you might want to do this a section at a time. Then select the MOVE icon and RIGHT click (right clicking selects the group instead of a single component) and drag the set into the board outline.

Turn Balls Into a Cube

Turn Balls Into a Cube

Introduction: BuckyBalls Turn Balls Into a Cube

Start by taking themessof balls and createa single straight line of the BuckyBalls. Be careful not to work around metals that will attract the balls because it is easy to misplace them which would make it impossible to complete the cube. Also, don’t let the magnets get to close to each other or they can attrach each other which makes it hard to peel them apart.

After taking the chain (while keeping the balls far enough apart to prevent an unwantedattachement) count 36 balls inlength and fold the balls to create a 6 by 36 chain (as seen in the photograph). The easiest way to make the 6 by 36 block is to zig zag and let the balls attach themselves. By doing so, this creates a simple network of magnets that can easily be turned into the cube. Keeping the chain on a flat surface to make sure that the magnets all connect at the same time,
Turn Balls Into a Cube
count 6 (this would make a 6 x 6 square) and fold it over so now it will look like two 6×6 squares stacked on each other. After doing so, carefully flip the entire system over with the two 6×6 squares on the bottom. Then fold the next 6×6 square on top so it looks like the photograph. To complete the cube, continue folding the chain over the started cube intil you now have a 6x6x6 cube!
Turn Balls Into a Cube

Note: If not done on a flat surface or done too quickly the cube will become warped due to polarity and it will be nearly impossible to undo the mistake which means it will be necessary to restart the entire process.
