Use of Instrument browser

In this part of tutorial we shall demonstrate work of the grid with large data volumes on the example of Instrument

browser.

The business model already contains Instrument class. We shall add only one field (quoting currency) and create a lot of instruments in the application (e.g. 100000). For this purpose we shall modify Provider class and create an arbitrary list of instruments. As before, this list will be available as follows. Now let’s bind the grid to the data source. Memory consumption is one of the most important aspects of displaying large data volumes. When grid connects directly to application business logic, it significantly reduces memory consumption because there are no intermediate objects between the data layer and its presentation.

Let’s create InstrumentBrowser control and place it at the main panel. We shall add a panel for instrument filtering and

searching and the grid to this control. We shall configure grid in the designer and link it to the data source.The screenshot below demonstrates the results of application work.

Let’s note an important detail. The collection of instruments contains about 100,000 elements. It is created when the application is launched. Total memory consumption of the entire application is about 45 MB. This collection is bound to the grid when Instrument browser tab is opened. After that, memory consumption increases to 59 MB. This means that the grid uses about 14 MB to display 100,000 elements. This amount of elements loads for about seconds.These indicators demonstrate of grid performance with realistic numbers of instruments.

To navigate large data volumes a high performance filter is required. The grid provides a simple API for filter implementation. In this application many instruments have Weight, Shares, Capitalization values equaling 0. For more convenient data interpretation it is better not to display insignificant zeroes. Besides, it is better to add thousand separators for data formatting. Use of formats is the simplest way to implement this functionality. An example of creating a simple format for displaying digital information is provided below.

Net Grid provides broad functionality of displaying various datagrid elements, such as cells, rows, headers and columns. The main objective of Dapfor is to develop high-performance software, specifically grids. Popular MVVM programming model that extensively uses databinding, data gridview to separate data from presentation.

Texas Instruments Ti-83 Plus Calculator

Calculators have shrunk in size and increased in price as consumers have sought out devices that do much more than simple arithmetic. Texas Instruments has their TI-83 Plus model which helps students with their Physics, Biology, Algebra, and Pre-Calculus classes. We’ll examine why this model is so popular with today’s classroom students.

Back in the 1970s, the slide rule gave way to calculators in many classrooms across the nation. Texas Instruments led the way as almost every student owned one of their models. Today, Texas Instruments [or, TI] continues to produce calculators and their TI-83 Plus calculator leads the way.

So, what sets this particular model apart from others? Well, it is pocket-sized, comes with 12MB of memory, does tons of math problems including statistical tests, has a complete alphabetical keyboard, and it can run programs to name a few. Still, if you are a Calculus student it doesn’t do Calculus. However, you can bring the TI-83 Plus along for standardized tests and college admission exams.

The device runs with 4AAA batteries, so you need to make sure you are fully charged before you start your tests or at least carry spare batteries with you.

The TI-83 is not cheap as you will have to pay about $100. for a new one. Expect to pay a lot more if you purchase one through your university’s bookstore; shop online to compare prices too.

The TI-89 may be a better option, especially if Calculus is in your future. Shop and compare and make sure that the model you want provides the calculations you need.

Things To Consider While Buying Autosampler For Your Hplc Instrument

High Performance Liquid Chromatography has indeed brought a sea-change in the way complex samples are analysed and tested. HPLC instruments have found their way in various industries where these are used for quality assurance, testing and much more. There are several components which make up an HPLC instrument and out of these autosampler is one of the most important. Autosampler helps you introduce samples into the inlet. You might argue that manual insertion is possible than why the need for an autosampler? Well, it helps in time-optimization and reproducibility as well. Countries such as the United Kingdom, United States & Italy have been at the forefront when it comes to designing & developing the autosampler technology. While buying autosamplers for your HPCL instrument, you need to keep in mind some points which are briefly discussed as under-

Begin by asking how many samples actually you need in your laboratory on a periodic basis. If you analyze thousands of samples, then investing in autosampler is a great idea! On the other hand, if you deal with limited samples, a manual injector does the needful for you at a lesser price. However, if you prefer accuracy than the cost-factor, autosamplers offer amazing results. Once you have dealt with this point, its now the time to ask what exactly are the size of samples that you need to analyze. It is a proven fact that autosamplers are far more efficient than human beings. Investing in an autosampler is a good idea even if you have to deal with low-volume samples in your laboratory.

After having analyzed these points, you need to know how fast your instruments cycle time and the sample loading speed are. It is worth considering these points in case speed is important to you. It is very much crucial to choose the right supplier when you are buying an HPLC autosampler. Find out the kind of services, support the supplier offers including warranty. Most importantly, you also need to find out the cost of buying the autosampler and maintaining it. Go for a supplier who offers complete technical support to you all round the year, whenever the need arises. It is better to invest a substantial time in choosing the right supplier because the quality of autosampler and the kind of support you get matters a lot.

Considering factors such as the ones described above will help you decide whether investing in an autosampler is worthwhile. In nutshell, autosamplers are not meant for every lab use. Many researches still rely on manual insertion because of the cost-factor linked with autosampler. However, if speed and accuracy are your priority, then autosampler can help achieve your target objectives in quick time.

The Musical Traditions And Instruments Of The Zulu

African music is the music of Africans who live in a large region of 50 nations, each with a special culture, history and language, South of Sahara. Zulu musical instruments are part of this multilingual culture. African music has some distinct characteristics: the use of repetition is one of them. Another important characteristic is the polyphony; this is the combination of different musical parts played simultaneously.

The history is marked by the awesome military strategies of the Zulu King Shaka. The King’s and his warriors’ campaign of expansion is well known in world history. Zulu rich traditional culture includes songs, dances and colorful rituals, Zulu musical instruments are spectacular and original. A variety of Zulu musical instruments are well known, s well as the traditional Mine dance; Zulus have longtime used their music as a cry for freedom.

African music is really rich in modes of expression: drum ensembles are using Zulu musical instruments from the percussion family. Each drummer uses special methods to produce sounds to distinguish his drum from the others. Iron bells are very popular Zulu musical instruments; they are used to produce a repeated sound to help the drummers to play at the correct time.

Zulu musical instruments, rare and very special
The akadinda is a king of xylophone; two groups of African musicians are playing simultaneously. The first group is playing repeatedly the same pattern; the second group plays to fill in the missing sounds. Groups of Zulu musicians play also using flutes, trumpets or xylophones. Each player plays a single note in a strange rotation with the other players. The result is a polyphonic piece, characteristic to African music.

Musical practices of South African people were observed from many years; Zulu musical instruments are obsolete. Venda mbila is an old Zulu musical instrument; it is not used anymore. Reed flutes, contrary, are still very popular. The influence of foreign cultures and civilizations causes many of old Zulu musical instruments to become obsolete.

Musical instruments such as tsonga – a horn, ingungu – a friction drum, nkoka – a drum, pedi – a flute, venda – musical bow and stick, deze and demba – thumb piano and resonatos, umfece – ankle rattles are almost obsolete.

To preserve this awesome heritage of Zulu musical instruments, the necessary information was entered into a database; each Zulu musical instrument was digitally photographed to preserve all information about it.

The Peoples Instrument

The abovementioned quotation was from the legendary guitarist Andres Segovia. It is by far the most appropriate description given to everyones favorite musical instrument the guitar.

Guitars are arguably the most popular and widely used among the musical instruments. It is the major instrument used in most contemporary music genres such as blues, country, rock and other forms of pop. Guitars are also played as solo classical which is usually done acoustically. Acoustic guitars rely on the vibrations the string produced and the hollow body that modulates the sound. Contemporary musicians, on the other hand, use mostly electric guitars that amplify and manipulate the sound produced by the strings using electricity and other gadgets.

The history and evolution of guitars is still a mystery to most musicians. Up to now, no one knows where guitars originated. Others think that the ancient Greeks are the ones who first use the instrument. Some others would say that it cam from North Africa, the Middle East or India. Guitars seem to be widely used everywhere most probably for that reason.

As strange as its origin, classic guitars are mysterious and solitary. Obviously, only one person is needed to make music with a guitar but as Segovia mentioned, the strings vibrating together seems to produce varying emotions to the audiences ears. This is specially the case with classic guitars which are usually played in solo concertos and rarely as an accompaniment.

Blues guitars are the complete opposite of the more demure classic guitars. Although blues started as more of a vocal exhibition while guitars were only used as rhythmic and harmonic accompaniment, there is no denying that blues has evolved to what it is now because of the guitar. The rhythm produced by the guitars best emphasize the lyrics of blues songs. And because blues musicians are usually self-taught, the guitar evolved as a very flexible instrument which musicians enjoyed to take advantage by exerting their own version of guitar playing that reflects their personalities. Using the guitar, blues musicians were able to develop its style making it hard to categorize it to a single genre.

Also very influential in todays music scene are electric guitars which are now considered as an artifact of popular culture. Electric guitars are predominantly used in rock, pop and jazz. May it be a Strat or Les Paul, electric guitars define our generation with its postmodern definition of music as an art form.
