Investman wants to take everyone back to the 19th century industrial revolution era.
As many people already know that
Britain is the first country in the world to have an industrial revolution since July. B.E. 1780
Followed by Belgium and France
While the economy of other countries in Europe is turning through to progress.
Germany just reunited countries by land which is now Germany. Just completely united for the first time on July. Year 1871 which is the same as the reign of King Rama 5 of the Kingdom of Siam.
From the gathering of German tribes led by the Northern Prussian Kingdom.
With little and big south under the lead of Emperor Wilhelm 1
And Prime Minister Ottoffon Bi Mark
The industrial revolution later made Germans not want to waste their time. Try wrong, try right.
To develop the country to thrive.
The important thing in this regard is to put the process of education and research systematically, therefore, the government puts ′′ education reform ′′ first.
Even many European countries have founded the university since medieval times.
But Europe's academics won't be much involved in the business and industry.
Academics are posing as ′′ gentlemen ′′ not doing business and not messing with industrial sector.
The mechanics, technicians, or anyone involved in the industrial sector will be seen as lower than academics.
But German education doesn't look that way..
With Germany's absence of colony and its revolutionizing industrial slower than many countries.
The only thing that could make the Empire that was recently advanced further than others.
It's scientific advancement, especially in ′′ applied science
Under the lead of Bismarck, huge educational budgeting occurred.
Educational welfare is founded in technical college.
Educational emphasis on Technician and Engineering Career Specifically
Berlin's Technical College of Berlin was established in Year B.E. 1879
Developed from the college of mining that was founded in kho. B.E. 1770
This place is currently the Technical University of Berlin (Technische Universität Berlin)
Apart from Berlin
Technical universities are also established at other states around the country during the evacuation time.
Technical University of Darmstutt, established in July. B.E. 1877
Hannopher Technical University established in July B.E. 1879
Having a unique university in Technician and Engineering
Make a lot of workforce and technicians
When these workers graduate, they can enter into industrial sector immediately.
Government also supports universities to cooperate with industrial sector.
There is a collaborative research between academics and businessmen in industry circles.
Engineering research is easily implemented in the business world.
When businesses can make profit, they give money back to support research.
Later on, many big companies start having their own research and development institutions.
Germany's engineering development is growing in a leap.
Especially in the steel industry.
The German Empire Steel Industry Center is located around the Roore River Valley.
Aka Ruhrgebiet (Ruhrgebiet) which is west of the country.
This area is a major source of iron and coal mineral, with an epicenter in Esseen.
But originally, most steel industries use mild steel, these iron are fragile.
Make it not yet applied for much use.
For steel to be stronger and more durable, it is necessary to transform the chemical structure of steel by fusing and filling the mineral into steel.
But ironing requires a very high temperature at the moment, no effective and cost effective stove for production.
How to produce Siemens-Martin Steel
Which was invented in July. 1865 by 2 researchers
One of them is German named Sir Carl Wilhelm Siemens
Created an accelerated steel squid oven that can heat up to 1,500 degrees Celsius.
It's called a pan stove or open hearth furnace.
With education system that strongly connects research and industrial sector.
Not long ago, German steel company brought a new refiner.
xỳāng rwdrĕw application in the steel industry
Led by steel company called ′′ Krupp ′′
Krupp company founded by the Krupp family has a history back to mid 16th century.
There is an office located in Esseen during which German railway expands rapidly.
Esen City becomes the center of the steel industry.
Krupp company also leads to manufacturing metal-based products such as railroad tracks and locomotives.
Alfred Krupp has funded research to find out how to produce steel.
Scholarship to the scholars when a new refiner comes out successfully.
Krupp company has become a leader in global export steel production.
From railroad tracks, development to machinery and factories.
Not long ago, Germany was on board, Europe's major steel manufacturer overtakes England.
Krupp company currently has merged with Thyssen steel company.
Became a ′′ Thyssenkrupp ′′ company.
Even the steel industry is going to lower the role.
But Thyssenkrupp has continued to be a leader in engine parts.
Aircraft, elevator and escalator components.
Apart from the steel industry, another industry in which German engineering knowledge has advanced over many countries during the same time is the electrical industry.
Led by a company called ′′ Siemens ′′
Founder of this company is Werner von Siemens Berlin electric engineer
This is the real brother of Sir Carl Wilhelm Siemens who invented steel production methods.
Werner von Siemens has automatically invented a typed telegram system.
Instead of knocking, using Morse code, then founded Siemens company in July. B.E. 1847
Siemens company has expanded its business across Europe and USA.
Werner von Siemens also the world's first electric elevator developer in July. B.E. 1880
The inventor of mechanical dynamo that transforms mechanical energy into electric energy.
And build an electric bus or Trolley Bus in July. B.E. 1882
Siemens are currently the world's leading electrical engineering company.
There are a variety of products from electronics, electric car, medical tools.
Electric train signal system to wind turbine technology
In addition to Thyssenkrupp and Siemens, the brand is under 100 years old.
Germany also has many engineering companies that all have the same age.
The whole Leica company founded in July. B.E. 1869
Expert in the production of eyelet lenses, medical devices and cameras.
AEG company founded in July. 1883 Manufacturer of large generator and tram system
Osram company separated from Siemens in July. Prof. 1909 is a leader in light bulb technology.
Dedication to developing applied science education and connecting to the business sector, opens new advancements in engineering.
And bring Germany to step up, standing in the front line of the world's leading industrial countries.
But not only the advancements in the steel and electrical industry.
Founded Technical University will produce important people in the science industry.
To take Germany to open the world into a new industry.
Industry that will forever change people's lifestyle
′′ The chemical industry "..

【模擬仿真越精確,意外越少、良率越高】
示波器 (Oscilloscope) 和訊號產生器 (Signal Generator) 可說是工程師的兩大基本配備——前者擷取訊號、後者生成訊號。在類比/類比數位混合訊號領域,任意波形產生器 (Arbitrary Waveform Generators, AWG) 應用非常普遍而廣泛,藉 AWG 產生訊號以模擬某種感測器便是其一。
例如,複製汽車碰撞實驗的訊號,或產生高速類比訊號來測試晶片功能。AWG 在各式範疇皆能應用,從簡單的正弦波產生器、到 AM/FM 調變、再到更加複雜的 QAM 調變訊號等,而高速放大器與類比數位/數位類比轉換器 (ADC / DAC) 的品質對於寄生訊號與雜訊影響甚鉅,另電源供應電路亦可能造成干擾。

GRANDIOSO K1X
"Two revolutions integrated. Two revolutions connecting people to music... The VRDS-ATLAS and Master Sound Discrete DAC - now come to fruition in an integrated player that carries the name… Grandioso ( Grandioso (music): Grand or noble)."
An unprecedented transport mechanism that invites you to the furthest reaches of sound.
VRDS (Vibration-Free Rigid Disc-Clamping System) is Esoteric's unique CD/Super Audio CD transport technology, which has been specially designed to clamp the disc to a same-diameter turntable in order to eliminate the disc's rotational vibration, as well as any extraneous vibration emanating from the mechanism itself. It also corrects any warpage of the disc, dramatically improving the accuracy of both the optical pickup and the disc pit layer's corresponding optical axis, while also minimizing servo current. This all adds up to dramatically reduced disc read error for exceptional audio quality.
The new VRDS-ATLAS platform boasts unprecedented mechanical perfection and superlative audio quality, with heavyweight construction that is fully 127% heavier than previous iterations (6.6kg for the mechanism alone, and 13.5kg including its base). This highest rigidity and weight in the history of VRDS mechanisms has the effect of greatly reducing any and all vibration that could adversely affect audio quality. The transport's larger new side panels and bridge are all formed of SS400 steel, and its turntable is made from duralumin, which is renowned for its excellent sound quality. Also, its spindle features a newly designed thrust bearing system, for a friction-free one-point spindle support system that ensures smooth, noiseless turntable rotation.
Esoteric's impressive VRDS-ATLAS is the quietest and most elegant transport in the history of VRDS. The key to achieving this was a resolute focus on mechanical grounding technology that more effectively reduces vibration.
Adopting a wide & low-profile design for the entire mechanism helped achieve a lower center-of-gravity, and relocating the turntable motor to below the turntable from its previous position above the bridge dramatically shortened the route for grounding vibration and reducing mechanical noise. Tray hollowing has also been minimized for increased rigidity, and special stoppers made from vibration-absorbing elastomer cancel out resonance when the tray is stored.
The Grandioso K1's mighty power supply was the key to its powerful and profound three-dimensional sound. With the introduction of its new X version, this power supply has been dramatically enhanced to add further depth to its exceptional audio tone. Its built-in D/A converter features independent power transformers for left and right channels, and the K1X includes a total of four independent toroidal power supply transformers. Furthermore, technologies cultivated in the development of the Grandioso P1X/D1X have also been adopted, including a new low-feedback DC power supply regulator featuring a discrete circuit configuration which contributes to its powerful open sound. The K1X also contains a total of 76 EDLC* supercapacitors (with a total capacity of 2,050,000µF or 2.05F). This greatly increased power supply capacity provides a tremendously improved sound quality for exceptional resolution in the lower frequency ranges.
*EDLC (Electric Double-Layer Capacitor):A special type of capacitor boasting an astoundingly high capacity compared to the electrolytic capacitors used in conventional audio equipment.
The VRDS-ATLAS transport mechanism is centrally located within the chassis, where it is fixed to a 5mm-thick steel bottom plate and supported by four proprietary pinpoint feet (patent no. 4075477 and 3778108). This effectively isolates the rotational mechanism from vibration. The internal structure of the chassis features a double deck design, with the audio boards on the upper level and power supply circuits and transformers on the lower level to minimize magnetic flux leakage and vibration, while also shortening the power supply wiring.
Semi-Floating Top Panel
The enclosure's top panel utilizes a screwless semi-floating structure that further contributes to an open and expansive sound.
Master Sound Discrete DAC
Bringing out all the dynamics and energy of the original master recordings.
Master Sound Discrete DAC Bringing out all the dynamics and energy of music.
Unattainable by integrated chips, our goal was to assemble carefully selected and tested discrete components into a complete circuit that could perfectly reproduce all the dynamics and energy of music. Our top engineering teams put their pride on the line to design and produce a quality of sound that can only be found in the Master Sound Discrete DAC discrete D/A converter.
The K1X's Master Sound Discrete DAC is the most revolutionary two-channel stereo DAC circuit in Esoteric's history, and is based on the original circuit developed for the Grandioso D1X monaural D/A converter.
As an extension of the D1X's design philosophy, a luxurious volume of materials have been invested in the construction of K1X's Master Sound Discrete DAC. For example, it features 32 separate elements for each channel. Key components such as a clock driver, logic circuit, and capacitors and resistors, are kept independent for each of these 32 elements to ensure the purest output without no loss of musical energy.
The K1X's independently developed Δ∑ modulator supports 64-bit/512Fs and the latest high-end digital formats, including of 22.5MHz DSD and 768kHz PCM signals. The FPGA's* dedicated digital processing algorithm was developed exclusively for the Master Sound Discrete DAC, and has been fully optimized for outstanding playback of both DSD and PCM digital audio data.
Advanced Quality Control
With a discrete DAC, where component tolerances are directly linked to arithmetic precision, highly advanced quality control is also required for the manufacture of electronic circuit boards. Esoteric's own in-house factory boasts some of the world's leading board mounting technologies, such as soldering performed in an oxygen-free furnace, which is located in a clean room featuring the same level of cleanliness found in a hospital operating room. Technologies cultivated in the production of electronic circuit boards for audio, medical, aerospace, and defense industries support the high production quality of the Master Sound Discrete DAC.
The ESOTERIC-HCLD output buffer amplifier boasts an amazingly high-speed slew rate (response speed) of 2,000V/µs. Current transmission and speed—the most important factors for an analog output circuit—have been pushed to the limits to reproduce the reality of music with a dynamic range that is truly breathtaking.
In addition to its XLR and RCA amplifier line connections, the K1X also features the ES-LINK Analog method of current transmission. Taking full advantage of the HCLD buffer circuit's powerful current supply makes the K1X less susceptible to the detrimental effects of impedance on the signal route. It also enables a more powerful signal transmission, fully driving connected compatible devices.
A high-accuracy clock circuit is the key to achieving superlative sound quality in digital audio playback. A top-quality clock circuit is truly the heart of any high-end digital player. The K1X now features the superb Grandioso Custom VCXO II clock originally developed for the Grandioso P1X/D1X. This clock was developed with carefully considered modifications made to the earlier model's internal circuitry and components to more vividly emphasize the K1X's ultimate audio quality while further boasting remarkably low phase noise and excellent center precision (±0.5ppm).
The K1X can also be connected to the Grandioso G1 Master Clock Generator for playback, with internal circuits synchronized to a 10MHz clock that features the same high precision as an atomic clock, enabling further pursuit of high sound quality.
D/A Converter Functions for External Input, D/D Conversion, MQA Support & USB Input
In addition to its coaxial and optical inputs, the K1X also features a USB type-B port that is compatible with both 22.5MHz DSD and 768kHz/32-bit PCM asynchronous signal transmission, thus enabling it to also be used as a stand-alone D/A converter. Functions are provided for upsampling a PCM digital signal to 2/4/8/16× (max. 768kHz) and converting PCM to DSD. The K1X is also compatible with MQA-CD decode playback and full MQA decoding for playback of various digital inputs including USB.*
*MQA certification is pending as of August, 2019, and support is scheduled to be added via a software update as soon as certification is complete.

Tips no. 1:Stay focus with your objective. Regarding the pace band I mentioned, here is the link to print out your customise pace band. Check this out: http://www.runbundle.com/tools/pace-band-generator Every 5km marker you can check once. The markers are available as the race organiser will set it up. So don’t worry about that.
Tips no. 2: Stay calm and relax. By practicing meditation. Stay in a quite room, listen to smooth music, close your eyes, count your breath. Breath in through your nose, breath out through your mouth. Count from 1 to 10 and repeat. After once you are calm and relax, practice imagery session, imagine you run smooth the whole race, look forward all the time, stay with your target pace pacer and finish strong. Check this out, link to full marathon race course preview video: https://www.facebook.com/getBiiB/posts/1016373578515860
Tips no. 3: Stay hydrated all the time. Monitor your urine output, make sure it is clear, or light lemonade at max. If is dark yellow colour, then you are in dehydrated status. Minimum of 2% of dehydration can impair endurance performance. You can drink up to about 200ml of water for every 15-20 minutes to replenish body water level. A normal adult men need to drink at least 2.5-3.7 litres of water a day and for women it will be about 1.8-2.3 litres of water, but in some cases like those who tends to sweat more, you need to drink more than the average amount here.
Tips no. 4: Follow your own normal routine. Do not try to do new things like trying out new food, sleep late, play other sports which might have the risk to cause food poisoning, stomach discomfort, injury and so on. Also you can start to load up carbs in your diet. Have 1.5x of normal amount of food but remember to top up the carbohydrates nutrients. 4 grams of carbohydrate per pound (0.45kg) of your body weight yo maximise glycogen storage.
Tips no. 5: Smile. Whether it is intentional or unintentional smile, it’s going to help in reduce the rate of perceived effort while you running at your target pace. Smile also signal our body to release endorphins, also known as happy hormone. This hormone going to boost up your mind and you will be having a positive mindset. And so, remember to smile ;) while u run.
