The Many Options For Aluminum Extrusion Shapes


With new technology and the natural properties of aluminum alloys, it is possible to create a wide range of different aluminum extrusion shapes. Creating different shapes all starts with developing a die which will produce the desired shape once the process is complete.

The most common aluminum extrusion shapes are those which are used to create square or rectangular bars as well as round or hexagonal shapes. However, there are also channel shapes, z-bar, solid round or square rod or bar, H-shaped aluminum corners and aluminum angles which are used in a variety of aerospace, automotive and aircraft applications.

How It Works

Aluminum extrusion is a very common process. It can be used to create amazingly complex shapes including hollow cavities within a pipe, T-slots and unique shapes which can then be cut to display a specific profile.

To create aluminum extrusion shapes a die is constructed which is like a mold. The hot aluminum is forced through the die using high-pressure rams in a confined space, moving the aluminum through the die and out the other side in the form required. Liquid or gaseous nitrogen is also pumped through the system to prevent the formation of oxides during the extrusion process.

After the extrusion process, the aluminum extrusion shapes are further processed. This includes using a stretching processes to release any internal tension and create straight sides and angles which will be true and identical to all other materials produced by the same die.

Internal cavities are formed during the process through a slightly more complex mechanism. Specialized pieces known as piercing mandrels or pins are located within the die to create the designed internal open space. After the extrusion is completed the aluminum extrusion shapes can be further processed to the desired finish.

Unique Shapes

It is possible to create very elaborate aluminum extrusion shapes with one pass. There are different components used in the aerospace industry which are formed using the extrusion process since they are continuous, strong and uniform in every aspect.

There is really no limit to the development of aluminum extrusion shapes for parts and components. Small parts such as those required in electronics and the communication industry can also be created using this process and it can be a very cost effective option when compared to machining and milling rod or bar to create the individual pieces.

Transgender woman dies after beating in Harlem, New York

Saturday, August 24, 2013

A transgender woman attacked in Harlem, New York last week died on Thursday after being declared brain dead and taken off life support. Police are treating the death of Islan Nettles, 21, as a hate crime.

They were called faggots, they were called he-shes, she-males, things of that nature

Nettles was walking with transgender friends early on August 17 when they met a group of men opposite a local police building. Police say a fight ensued after the men discovered the group was transgender and local man Paris Wilson, 20, was arrested at the scene.

Wilson was charged by prosecutors in Manhattan with assault and harassment. Prosecutors say more serious charges could be brought after police received allegations homophobic language was used, with a hate crimes team now investigating. The death has been ruled a homicide and a spokeswoman for the New York City medical examiner’s office said Nettles was killed by “blunt impact head injuries”.

The criminal complaint Wilson presently faces says a police officer found Nettles “unconscious on the ground with a swollen shut eye and blood on her face”. Wilson is accused of punching Nettles to the ground and then repeatedly hitting her while she lay there.

Fashion became a definite decision for my life after my first show with my hand designed garments in high school

Nettles was interested in a fashion career, working as an intern for local fashion firm Ay’Medici. “Fashion became a definite decision for my life after my first show with my hand designed garments in highschool”, she wrote on LinkedIn, where she described herself as “anti-violence”. She has previously instructed fashion at Harlem Children’s Zone, undertaking studies at New York College of Technology and the Bread and Roses Integrated Arts High School.

Her mother, Dolores Nettles, told press Nettles and her friends were subject to transphobic insults. “They were called faggots, they were called he-shes, she-males, things of that nature,” she said.

Daniel L. Squadron of the New York State Senate said yesterday in a statement “Islan was 21 years old — 21 years old. And her life and future were stolen from her. Let’s be clear: intolerance, discrimination and hate have no place in New York or anywhere.” He called for the passage of a related bill he supports, the Gender Expression Non-Discrimination Act.

Wilson is presently free on bail, with a court hearing scheduled for October 4.

How To Learn Data Science

Brief about Data Science Learning

Learning data science can be hard, but it doesn’t have to be impossible. You just need to know what you’re getting into. I’ll share with you some tips that will help you get started. It’s important that you realize this isn’t for everyone, and there is a lot of competition out there. However, if you’re willing to stick with it, you’ll reap the rewards in no time.

You need to think long and hard about what type of formal education you’re going to need. There are many types, so you need to decide what’s best for you. If you like college, then you’ve probably figured out what type of formal education you need. If not, you might want to consider taking classes online or through an institution. No matter what you choose, there is enough to cover this topic that you’ll be prepared.

What to Study ?

Next, you need to figure out what you want to study. This can be done by listing your interests and defining the tools and materials that you’ll use. You might want to do a little bit of analysis as well, such as looking at existing data sets or trying to predict the future. It’s really up to you.

Once you know what you’re going to do, you can start thinking about how to get started. You can take a course at your local college. Some colleges even offer online courses for learning. If you prefer the written word, you can always read books on the subject or check out websites to see data sets and other examples.

If you’ve already got some education, you can read up on specific subjects and begin studying. This can be done at home, on the Internet, or in a library. There are many ways you can learn. The fastest way, of course, is to download eBooks on the subject and begin learning immediately. You’ll save money and get instant results.

Some good learning resources

You can also learn online or through video tutorials. There are many websites offering tutorial type courses on how to learn data science. These courses are designed to be self-directed or interactive. They usually involve learning scientific concepts using specific software applications. You might find that the best courses are those that combine text with video tutorials. I particularly would refer these two websites as I have been a contributor myself in their content. Imurgence forself paced data science courses and Integrumlitera for One on One machine learning courses.

These programs are designed to give you hands-on experience with actual data science projects. Some are based on experiments you might do at home. Others are more project based than anything else. Whatever you choose, you need to be aware that learning this way is just that: learning. Don’t become so confident in your understanding that you think you understand it all.

Remember that as you learn you need to keep things interesting. Keep re-thinking things and questioning yourself. Be willing to accept that things don’t always work the way you expected them to. You’ll find that the more questions that you ask and the more independent data you collect, the more you’ll learn about data science in the process. The better you get at it, the more value you will earn.

While the science part of this is important, remember that you’re also learning to communicate. In the beginning, you should probably use a visual tool to make simple expressions and plots. Over time you can probably move beyond that. It’s okay if you don’t know everything right from the beginning. You should be able to figure out what to write in your own words. You don’t need to understand everything right now, but you should gather some knowledge at each step of the way.

Once you have some initial data, try to backtest it. This means looking at how your system or application performs against a known set of standards. This lets you see what kind of effect you may have had if you tweaked the system to its maximum potential. If you find that it still performs poorly, consider changing your approach.

Parting Views

Finally, you want to find out if there are other people who are learning the same things as you. This is where message boards and forums become useful. Find others with the same goals as you and ask for tips and advice.

There is a lot involved in understanding how to learn data science. However, once you have some preliminary knowledge, you can proceed with confidence. You will be ready to take on more advanced tasks. And even if you never go beyond a basic program, having the basic foundation will help you be prepared to move forward when you choose. This holds true for almost every subject you might choose to study.

Audio Expert A Music Organizer Software That Leads To A Straight &Amp; Clean Media Library

AudioExpert – A music organizer software that leads to a straight & clean media library


Ulrich Decker

This easy-to-use music organizer software guides you through the process of getting your music files in a well-ordered and clean state. This article outlines the three steps so you can get an idea of AudioExpert\’s capabilities.

A screenshot of AudioExpert\’s mainform can be found at

Step 1 – Import

Before you can start your work with AudioExpert, you will have to import your musicfiles. You can easily import songs from different locations or external drives. AudioExpert also lets you import your iTunes media library.

Unlike other tools, AudioExpert will start the cleanup process already at this point: Duplicate songs will be detected and the version with the best quality will be preselected. The parameterizable, fuzzy matching engine will detect minor misstypings and puts songs e.g. of \”Marillion\” and \”Marilion\” into the same node. Of course, you can review the found duplicates right after the import process.

Step 2 – Cleanup

After the import process, the imported files are shown hierarchically so you can easily rearrange songs, albums or artists. Please note: AudioExpert shows a preview of how your files will look like whenever you decide to apply the changes (see below). The files will not be changed immediately while editing!

YouTube Preview Image

It is possible to reassign songs or albums using the drag & drop feature: The ID-tags for artist and/or album will automatically updated based on the place where you drop the items. Whenever you rename an artist or album, all songs of this artist/album will be updated and you will keep the same notation everywhere.

The inplace editor allows editing the most common tags directly in the listview. A mass-updates for manually selected tracks is available, too.

For even more complex tasks, AudioExpert provides a large toolset containing e.g.:

– A powerful autotagging feature that identifies even completely untagged files

– A mass-update function using predefined regular expressions. Skilled users can define their own expressions, of course.

– Normalizing the loudness of MP3 or OGG files using ReplayGain or MP3Gain

– Searching album covers and lyrics (via amazon or google)

– Searching for erroneous musicfiles

– Adjusting the notation (case sensitiveness) for artist, album and songname

– Finding duplicates using an acoustical fingerprint or the md5-checksum of the audiopart

– Aligning artists and albums with MusicBrainz

– Importing musicfiles from CD and convert the e.g. to MP3

– Converting codepages or wrongly UTF8-encoded texts.

Step 3 – Committing changes

If you are satisfied with your work, it\’s time to apply the changes to the files. AudioExpert can not only adjust the ID-tags of the files. It can also update the filenames using user-defined format-strings. And it can move or copy your files to the new location and structure. The folder-properties-dialog allows you to define the structure for each folder separately.

If you have also imported your playlists, AudioExpert will update the playlists so they will still work even if the files were renamed or moved.

In addition, you can export your changes back to your iTunes media library!

What\’s next?

Besides of the mentioned features, AudioExpert is a powerful music player and playlist creator. The high-performance search dialog (works fast even with 200,000+ files) helps you finding your files.

Owner and manager of Moroccan factory arrested over 55-fatality fire

Sunday, April 27, 2008

Police have arrested the owner of a mattress factory in Hay Hassini, Casablanca, Morocco which burned down in a disaster that claimed 55 lives. His son, who was the factory’s manager, was also arrested.

Those killed — 35 of whom were women — were trapped inside by locked fire exits, which were barricaded to stop theft during working hours. “The people who died were either asphyxiated or burned,” commented a firefighter. 17 were wounded. Moustapha Taouil of the Casablanca civil protection service said the blaze was triggered by an inadequatly maintained electric saw on the ground floor. The initial fire quickly engulfed all four storeys of the building.

The Rosamor factory was clearly operating unsafely, officials said. “It’s a building with a ground floor and three upper floors specialising in making furniture, therefore there were highly inflammable products,” said Taouil. “We confirmed during our examination that the owners of the premises failed to respect legal requirements for this kind of industry including staff training… the owner in contravention of the law, locked staff inside the plant apparently to prevent theft of raw material. It was this that prevented them getting out. The fire was caused by lack of proper maintenance of certain machines and electrical installations.” He said a short circuit on the ground floor, which was filled with power saws, triggered the disaster.

As a result of the investigatons, “The plant’s owner, Adil Moufarreh, and his son Abdelali Moufarreh, who was the manager, have been taken into custody after having been questioned by police,” said an official.

28-year-old factory employee Fadila Khadija said “There was no emergency exit, the extinguishers were empty and the working conditions were difficult.” One source said that windows were also unusable as they were covered with iron bars. 20-year-old survivor Omar Elaaz said “I was working on the first floor as an upholsterer. The smoke came up from the ground floor where the foam rubber, wood and glue are stored. I used a gas bottle to break the wire mesh that protects every window.” 31-year-old upholsterer Hakim Hakki told of his own lucky escape and its effect on him from hospital: “I jumped from the third floor with four other colleagues while the women, who didn’t dare to follow us, perished in the inferno. God saved me but I’ll never forget those who died.”

The father of deceased 19-year-old Abdelazziz Darif said his son was paid 250 dirhams (20 euro/31 US dollars) per week and did not have social insurance.

The Complete Guide To Choosing An Online Stock Broker

We are a generation of fast-paced technology and quick transactions. The transition from searching for reports in the systematic manner in the library for hours to saying “hello google” has been quite rapid. The financial market is not unknown to this changing attitude as well. Since the world saw an immense growth in the online system especially during the year of 2020, the online game changers have been the online stock brokers. Launched during the last decade and evolving in their functionality, they have their fair share in the market. What’s in it for you is that this particular decision could be the difference between an exciting source of income or a frustrating disappointment. While there is no magic trick to make quick profits, there is a still a way to set yourself a way to succeed. First, let us understand who these online stock brokers are and how they make a difference.

Who are the Online Stock Brokers? How are they different from the traditional brokers?

In plain terms, an online stock brokers is the one that interfaces with customers over the Internet instead of face-to-face. They work same as the middlemen like the traditional brokers but operate online but the work ability is quicker and efficient. They have a faster processing of trades and have greater control to execute any function. It is also convenient for you as you can place orders, check quotes and make changes from anywhere you want to. It is far easier now than ever to open an online brokerage account. Some of the common example are Zerodha, Upstox, Angel Broking, IIFL, etc.

The steps you need to know to choose your perfect online broker

There are several steps attached to choosing the right online broker which requires some due diligence to get the most for your money and investment:

Step 1: List down what you need

Before diving into this pool of brokers you must analyse where you stand in terms of your experience. As a rookie, you will be looking for basic education resources, easy practices to trade, support staff and other methods to check the level of the platform but as an experienced investor, you might want to look at the condition of order options, the fixed-income securities and ability to trade derivatives, mutual funds and others. You need to be honest with yourself and keep refining your goals as you will face further questions in your journey. Some questions you might have to answer yourself are:

  • Are you looking for a full time investing experience daily or a long hold position?
  • What is your experiences and what kind of trades you wish to execute?
  • What are your goals and what are you choosing investing for?

Once you are clear with the solutions of these questions, you’ll yourself be able to distinguish between the platforms.

Step 2: Negation works well

Remember when in the MCQs, you didn’t know an answer so you removed the ones which seemed far-fetched and came down to 2 out of 4. Similarly, you can narrow down the brokers based on the services you are looking for. One should check out if the brokerage firm a member of the Securities Investor Protection Corporation (SIPC), Financial Industry Regulatory Authority (FIRA), and offers checking or saving accounts covered by the Federal Deposit Insurance Corporation (FDIC). You should also question on their insurance policy, protection against fraud and the reviews of their current customers. Some other points to look at are:

  • Technology used to keep your account safe.
  • If the company selling your information (Beware of that)
  • What kinds of account does the broker offer beside the standard investment accounts?

Step 3: Figure out the Fees

A clear idea should be there in your mind when you have to pay a higher or a lower price for the same features on different platforms. Also, you would like to lose as little of your investment returns as possible to accounting fees and trading commissions. There are several charges attached so note these ones to compare and consider:

  • Fees for opening an account
  • The minimum amount of balance to be kept
  • Annual and monthly charges accompanied
  • The margin rates and the minimum loan amount
  • The factors on which trading commission depends
  • Commission rates for different securities
  • Are there any free or reduced priced trades?
  • What is the costing for the advisory services?

Step 4: The Platform is the Master

The access of online brokers requires everyone to have a fast processing interface which provides easy accessibility and have variety of tools. One must analyse all the platforms, their tools, their packages, features and how the trade is taken place on those platforms. Some questions you might ask yourself here are:

  • Do the platform allow to trade all types of securities?
  • Do you have a real time screening of the stock prices?
  • Can you set up watch list and alert for further news and notifications?
  • Kinds of orders that you can place
  • Your control over the whole trade transaction
  • And other features as available

Step 5: Education Component

Consider yourself who wants to inquire and know about certain terms, will you keep on switching between tabs or want them altogether at one place? User-friendly is one thing but to search the broker’s platform to know about the educational offerings, the source of the information, the accessibility of the information, and the beginner’s guide to investing.

Step 6: The Ease of depositing and Withdrawing Funds

To transact is to deposit and withdraw and you should compare the modes through which you can deposit your money, the duration for your deposited funds to settle, the regular checks of the funds, the duration for your sale of investments to settle and the ease to withdraw funds.

Step 7: Customer Service

Till this point, you might have made your choice but if you still not there, you might consider during and after services of the online broker. See if they are easily available around the clock or not is there any reporting system if you are into any troubles or an automated number for general queries.

Should you prefer them in the long run?

With the progress, there lies some insecurities as well. To trust, it needs care and you need to be careful to avoid any scammers out there. There are many online broking platforms out there but you must be aware not to get trapped in the web of low price or additional features. Check the authenticity because it’s your money after all.


Since we know all about the online broking system and how to select the best one for us, what are you waiting for? It is time for you to select the best of the best and invest in the company of your profitable choice. Keep refining your market knowledge with legal, financial and daily news where you get to learn through which you earn. For any further doubts or queries, if your online stock broker is not able to provide it, you know the right place to come to.
