What should be the proper/effective way to apply for a lecturing job at universities here assuming no cables at all?
Anyone ever got called for interview by just applying through those uni websites?

Paragraph to translate into Malay

theseriouscat — Fri, 10 Dec 2021 11:09:37 +0800

Anyone good at Malay can help me revise the below paragraph in Malay? I used google translate to translate it from English into Malay. This text do have a lot of technical terms though.

English text:

Hydraulic fracturing is a well operation widely used in the oil and gas industry to enhance the recovery of hydrocarbons in reservoirs. Studies on mathematical modeling of hydraulic fracture propagation have been developed from the very early stage of hydraulic fracturing technology. Essentially, most fracture propagation models are based on coupling elastic response of the rock deformation and pressure-driven viscous fluid flow in the hydraulic fracture. These models are classified as two-dimensional (2D), pseudo-three-dimensional (P3D) and planar-three-dimensional (PL3D) models. Each type of model has its own pros and cons based on their model simplifications and solution method. This research focuses on developing a P3D model with a variable injection rate at the wellbore as a suitable engineering tool, which is more accurate than 2D models yet less computation-intensive than complex PL3D models. The wellbore injection rate is defined as a power-law function of time. The governing equations are formulated based on linear elastic fracture mechanics for the rock deformation and lubrication theory for the pressure-driven viscous fluid flow in the hydraulic fracture. The fluid leak-off to the reservoir surrounding is accounted following one-dimensional Carter’s law. The governing equations are scaled into a nondimensional nonlinear system which is solved using an implicit collocation scheme with fourth-order accuracy. The P3D model is then validated against the PKN analytical solutions for the cases of storage and leak-off-dominated regimes. Finally, the validated P3D model with a variable injection rate is employed to investigate the effects of some controlling parameters (the variable injection rate, the fracture toughness and the leak-off coefficient) on the behavior of hydraulic fracturing propagation. The result shows the lateral growth was significantly affected by variable injection rates at the wellbore and the leak-off coefficient, while the impact of the fracture toughness is most significant on the fracture width evolution.

Malay text using google translate:

Keretakan hidraulik ialah operasi telaga yang digunakan secara meluas dalam industri minyak dan gas untuk meningkatkan pemulihan hidrokarbon dalam takungan. Kajian mengenai pemodelan matematik perambatan patah hidraulik telah dibangunkan dari peringkat awal teknologi patah hidraulik. Pada asasnya, kebanyakan model perambatan patah adalah berdasarkan tindak balas elastik gandingan ubah bentuk batu dan aliran bendalir likat yang didorong oleh tekanan dalam patah hidraulik. Model ini dikelaskan sebagai model dua dimensi (2D), pseudo-tiga dimensi (P3D) dan model satah-tiga dimensi (PL3D). Setiap jenis model mempunyai kebaikan dan keburukan tersendiri berdasarkan penyederhanaan model dan kaedah penyelesaiannya. Penyelidikan ini memberi tumpuan kepada membangunkan model P3D dengan kadar suntikan berubah-ubah di lubang telaga sebagai alat kejuruteraan yang sesuai, yang lebih tepat daripada model 2D namun kurang intensif pengiraan berbanding model PL3D yang kompleks. Kadar suntikan lubang telaga ditakrifkan sebagai fungsi undang-undang kuasa masa. Persamaan yang mengawal dirumuskan berdasarkan mekanik patah elastik linear untuk ubah bentuk batuan dan teori pelinciran untuk aliran bendalir likat yang dipacu tekanan dalam patah hidraulik. Kebocoran bendalir ke sekitar takungan dikira mengikut undang-undang Carter satu dimensi. Persamaan pentadbir diskalakan ke dalam sistem tak linear bukan dimensi yang diselesaikan menggunakan skema kolokasi tersirat dengan ketepatan tertib keempat. Model P3D kemudiannya disahkan terhadap penyelesaian analisis PKN untuk kes penyimpanan dan rejim yang didominasi oleh kebocoran. Akhir sekali, model P3D yang disahkan dengan kadar suntikan berubah digunakan untuk menyiasat kesan beberapa parameter kawalan (kadar suntikan berubah, keliatan patah dan pekali kebocoran) ke atas kelakuan perambatan patah hidraulik. Keputusan menunjukkan pertumbuhan sisi dipengaruhi dengan ketara oleh kadar suntikan berubah-ubah pada lubang telaga dan pekali bocor, manakala kesan keliatan patah adalah paling ketara pada evolusi lebar patah.

Thank you.

Next year I may have some free time and thinking about blogging.

I got some knowledge about a certain technical field and want to start blogging then find ways to monetize like creating courses to sell or writing a book... I wonder if its doable for me or just a waste of time.

Anyone have done similar things and got tips about how to generate traffic or promote your work? Does it sound realistic for someone who don't use facebook, twitter... to get into this kind of biz? how long it took for you to start earning from blogging?

Sending a laptop to Sabah

theseriouscat — Thu, 25 Nov 2021 10:37:24 +0800

I'm planning to send a used laptop to a friend from KL to Sabah by Poslaju or JnT.
Is it safe to do so? Anything I can do to reduce the goods damage during shipping?

MCO sucks! Come rate my cooking skills for fun

theseriouscat — Sat, 08 May 2021 12:18:21 +0800

MCO again and it sucks.
Come rate my chef skill and see if I can take a loan to open a restaurant in Malaysia.

Note: These are all sort of hybrid Asian and non halal dishes I started learning from MCO 1.0 till now

What would you do if?

theseriouscat — Sun, 12 Apr 2020 01:19:24 +0800

Suppose you are a foreigner working in Malaysia. Your embassy is planning to help bring your people home in case MCO extends some more.

The nature of your job allows you to work from anywhere. The thing is, if you go back to your home country you'll have to be quarantined 14 days first then might have to return to Malaysia shortly if things get better here. Staying here is not as safe and you feel not rested and stuck inside the four walls most of the time.

What would you do in such situation?

To do more with less

How does a nation with limited resources confront a global pandemic that has brought many developed countries’ healthcare systems to a breaking point?

That’s the challenge facing many of the world’s poorer, developing nations - including countries like Viet Nam. But while it might look like a foregone conclusion that the coronavirus outbreak would ravage such a country, Viet Nam has instead stood out as a beacon of how to do more with less.

So far, the country has 194 confirmed COVID-19 coronavirus cases, and no fatalities. Unlike other, wealthier Asian countries, Viet Nam isn’t in a position to conduct mass testing programmes. South Korea, for example, has tested 338,000 people. In Viet Nam, that number stands at just 15,637 people (figures for 20 March 2020). But by focusing on measures that are within its control, the country has won praise from the international community.

Swift action

On 1 February, Viet Nam kicked off a series of initiatives to tackle the spread of COVID-19. It suspended all flights to and from China. It also decided to keep schools closed after the lunar New Year break. Two weeks later, a 21-day quarantine was imposed in Vinh Phuc province, north of Hanoi. That decision was sparked by concerns over the health status of migrant workers returning from Wuhan, China, where the virus originated.

Viet Nam's proactive efforts come after two decades in which the country has experienced a large improvement in quality of life. Between 2002 and 2018, an economic transformation helped to lift more than 45 million Vietnamese out of poverty. Gross domestic product (GDP) per capita has more than doubled, to over $2,500 in 2018, when the country saw real GDP growth of 7.1%. The health of the nation has improved, too – life expectancy rose from 71 years in 1990 to 76 years in 2015.

The country’s healthcare system is improving, too, but still has a lot of ground to cover. There are around eight doctors to every 10,000 people in Viet Nam. Italy and Spain both have 41 doctors per 10,000 people, the US has 26, and China 18.

Its anti-coronavirus measures have gone on to include mandatory 14-day quarantines for anyone arriving in Viet Nam and the cancellation of all foreign flights. It has also isolated infected people and then set about tracking down anyone they might have come into contact with.

“Neighbours know if you come from a foreign country,” said Truong Huu Khanh, head of the department of infectious diseases at Ho Chi Minh City Children’s hospital. “If an infected person is in the area, they will report this.”

Neighbourhood watch

As a single-party state, with large and well-organized military and security services, Viet Nam has been able to make decisions quickly and enact them promptly. There is also a strong culture of surveillance, with people expected to inform on their neighbours if they suspect any wrong-doing. Anyone found sharing fake news and misinformation about the coronavirus risks a visit from the police, and around 800 people have been fined so far.

It’s not the kind of approach that is likely to work in more open societies. But with limited clinical resources at its disposal, Viet Nam has seemingly managed to get the outbreak under control.

Meanwhile, nearby Thailand has so far recorded four COVID-19 deaths, but is experiencing a significant rise in infections. On 24 March, Thailand’s Public Health Ministry announced 107 new cases, bringing the total to 934. The fault, according to Dr Taweesin Visanuyothin of the ministry, lies with “partygoers (who) transmitted the disease to about 100 other people … at-risk people must obey social distancing, both at their workplaces and at home.”

Another close neighbour, Myanmar, is drawing criticism from some for what has been perceived as a lack of transparency over the outbreak. Aung San Suu Kyi, Myanmar’s civilian leader, claimed recently the country had no cases of COVID-19, although that figure now stands at three.

The government has made claims that “lifestyle and diet”, along with people’s preference for cash instead of credit cards, was keeping Myanmar safe from the illness. These and other similar statements drew the ire of Phil Robertson, Deputy Director, Asia Division of Human Rights Watch, who said: “Such irresponsible statements clash with everything known about the coronavirus outbreak, defy reality, and only serve to give a false sense of security to the country’s people about the disease and their risks of infection.”
