Reverse engineering, local experts must for prosperity: Engr. Najeeb Haroon
IEEEP confers Life Time Achievement Award on Engr. Irfan Ahmed

on 26/06/2023

Chairman Pakistan Engineering Council (PEC) Engr. Najeeb Haroon has said that to improve the country’s economy, work on reverse engineering needs to be done, adding that “we have let our engineers down”. While energy remains a priority, IT and agriculture should be given due importance to improve the economy of Pakistan.
He was addressing as the Chief Guest at the IEEEP Multitopic Symposium 2023 held in Karachi with the presence of a large number of engineers and professionals from all over the country.
Earlier Engr. Khalid Pervez, leading the organization’s Karachi chapter highlighted the need of promoting a ‘Made in Pakistan’ approach.
Engr. Najeeb Haroon said that in small items we import even staplers. In large-scale industries, local value addition needs to be drastically improved.
The western world needs engineers, and perhaps we can earn foreign exchange by body leasing while we create jobs for our engineers in the Country.
We will have to think seriously in this direction,” he said adding that PEC engineers were supposed to work as “a brain” of the country. Unfortunately, the brain is not being used therefore nothing is coordinated.
Instead of its engineering experts, other unconcerned people are in the decision-making positions in every department, due to which no department is working properly.
The PEC Chairman asserted that for some reason the bureaucracy despises the engineering community and has no respect for the best-educated people in the country. This is the reason why good-performing college students are losing interest and admissions to engineering universities are falling. This trend needs to be changed.
He agreed with Engr. Khalid Pervez that “Make in Pakistan” should be part of our policies. Locally manufactured goods should be preferred. For the development of Pakistan, it is necessary to use the services of local experts.
A senior member of IEEEP, Engr. Irfan Ahmad who was the Chief Guest of the closing session being the recipient of this year’s IEEEP Life Time Achievement Award said that while the Country needs its brain, it is being drained out to the West. Only last year, hundreds of Pakistani engineers left for greener pastures as we are only producing job seekers in our universities. We do not even see what is inside the box itself. The doors of the West are now closing down for the outsiders. Only last month Amazon fired 18,000 of its workers and Google fired 12,000 people, including 450 Indian engineers. India was however quick to find jobs for its engineers in other countries. Our government on the other hand has not yet been able to provide an even service structure for engineers.
In the Symposium,18 technical papers on power, energy, telecom, and electronics were presented in various sessions, which also included a Panel Discussion on local manufacturing issues.

Leading exploration, production companies move to green energy

on 26/06/2023

Six Pakistani oil, and gas companies sign MoU for joint ventures; 15% of global energy-related greenhouse gas emissions come from oil and gas exploration
Leading oil and gas exploration companies in Pakistan have joined hands to
explore and pursue green hydrogen prospects, says the Petroleum Division of Pakistan’s Ministry of Energy.
These exploration and production companies include Oil & Gas Development Company Limited, Pak-Arab Refinery Limited, Pakistan Petroleum Limited, Mari Petroleum Company Limited, and Government Holdings (Private) Limited.
It merits mentioning that oil and gas are often painted as the dirtiest sector within the energy industry, but major companies around the world have begun to invest in renewable technologies in a bid to clean up the economy.
Of the six “super-majors” – BP, Shell, Chevron, Total, Eni, and Exxon – many of them have pumped billions into clean energy projects, although question marks remain over whether they are doing enough.
Despite the growth in renewables, “big oil” only spent 1% of its combined budget on green energy schemes in 2018.
The Petroleum Division says these companies in Pakistan have signed a memorandum of understanding (MoU) for joint ventures in the future.
The MoU will be initially effective for two years from the date of signing and it will engage consultants and advisors to explore the opportunities.
Under the MoU, the companies will also establish a joint fund to raise equity for joint ventures and green energy initiatives, said the statement.
Additional Secretary of the Petroleum Division Muhammad Mahmood, who witnessed the event, said that the collaboration could drive the energy transition towards a more sustainable future, leveraging each company’s expertise and resources.
“This collaboration is a significant step towards building a more sustainable future for Pakistan and beyond,” added the official.
On the occasion, Managing Director of the Oil & Gas Development Company Limited Ahmed Hayat Lak said, “we are confident that by leveraging our collective expertise and resources, we can accelerate the energy transition and create a greener, cleaner, and more prosperous future.”
The IEA’s Oil and Gas Industry in Energy Transitions report says while some oil and gas companies have taken steps to support efforts to combat climate change, the industry as a whole could play a much more significant role through its engineering capabilities, financial resources, and project-management expertise.
“No energy company will be unaffected by clean energy transitions,” said Dr. Fatih Birol. “Every part of the industry needs to consider how to respond. Doing nothing is simply not an option.”
The landscape of the oil and gas industry is diverse, meaning there is no single strategic response but a variety of approaches depending on each company’s circumstances.
“The first immediate task for all parts of the industry is reducing the environmental footprint of their own operations,” Dr. Birol said. “As of today, around 15% of global energy-related greenhouse gas emissions come from the process of getting oil and gas out of the ground and to consumers. A large part of these emissions can be brought down relatively quickly and easily.”
Reducing methane leaks into the atmosphere is the single most important and cost-effective way for the industry to bring down these emissions. But there are ample other opportunities to lower the emissions intensity of delivered oil and gas by eliminating routine flaring and integrating renewables and low-carbon electricity into new upstream and LNG developments.
“Also, with their extensive know-how and deep pockets, oil and gas companies can play a crucial role in accelerating deployment of key renewable options such as offshore wind, while also enabling some key capital-intensive clean energy technologies – such as carbon capture, utilisation, storage, and hydrogen – to reach maturity,” Dr. Birol added. “Without the industry’s input, these technologies may simply not achieve the scale needed for them to move the dial on emissions.”
Some oil and gas companies are diversifying their energy operations to include renewables and other low-carbon technologies. However, average investment by oil and gas companies in non-core areas has so far been limited to around 1% of total capital spending, with the largest outlays going to solar PV and wind. Some oil and gas companies have also diversified by acquiring existing non-core businesses – for example in electricity distribution, electric-vehicle charging, and batteries – while stepping up research and development activity. But overall, there are few signs of the large-scale change in capital allocation needed to put the world on a more sustainable path.
An essential task is to step up investment in fuels – such as hydrogen, biomethane, and advanced biofuels – that can deliver the energy system benefits of oil and gas without net carbon emissions. Within 10 years, these low-carbon fuels would need to account for around 15% of overall investment in fuel supply if the world is to get on course to tackle climate change. In the absence of low-carbon fuels, transitions become much harder and more expensive.

Self-Contained Embedded Designs of Microcontroller

on 26/06/2023

As a self-contained system containing a CPU, memory, and peripherals, a microcontroller can be utilized as an embedded system. Most microcontrollers in use today are integrated into other pieces of equipment, including computers, smart phones, gadgets, cars, and other technology. While some embedded systems are highly advanced, many have modest memory and programme length requirements, no operating system, and simple software. Typical input and output devices include switches, relays, solenoids, LEDs, tiny or specialized liquid-crystal displays, radio frequency devices, and sensors for data like temperature, humidity, light level, etc. Embedded systems typically lack the keyboard, screen, discs, printers, and other recognizable I/O devices of a personal computer. They may also be devoid of all forms of human interaction hardware.
If field-programmable devices are used on a microcontroller, late factory changes to items that have been produced but haven’t yet shipped may be possible. Additionally, programmed memory shortens the lead time needed for the launch of a new product. It may be cost-effective to use parts that are programmed at the time of manufacture when hundreds of thousands of identical devices are needed. The programme is laid out in these “mask programmed” regions at the same time as the chip’s logic. Since it would be expensive to furnish a system with extra, expandable storage, micro-controller programmes typically have to fit in the available on-chip memory. Both assembly language and high-level code are translated using compilers and assembly lines into a little machine code that may be stored in the microcontroller’s memory. The programme memory may be easily removable read-only memory, field-alterable flash, or persistent, read-only memory that can only be programmed at the manufacturer, depending on the device.
Numerous embedded systems require the ability to read analogue signals from sensors. This is what an analog-to-digital converter is used for (ADC). Analog signals that may be supplied to a processor by a device are useless since processors are designed to understand and handle digital data, or 1s and 0s. In order to transform the incoming data into a format that the processor can understand, an analogue to digital converter is employed. A digital-to-analog converter (DAC), which is a less common function on some microcontrollers, enables the processor to produce analogue signals or voltage levels.
The architecture of microcontrollers varies greatly. In some designs, the ROM, RAM, or I/O functionalities are incorporated into the package along with one or more general-purpose CPU cores. Others have been specifically created for control applications. In order to reduce the size of control programmes, a microcontroller’s instruction set typically contains a large number of instructions for bit manipulation (bit-wise operations). To test a bit in a register and branch if the bit is set, for instance, a general-purpose processor might need several instructions, whereas a micro-controller might just need one instruction to do the same frequently needed operation. Since most microcontrollers lack a math coprocessor, floating-point arithmetic is often carried out by software. But some current architectures do have FPU and DSP optimization features. The PIC32 MIPS-based series by Microchip is one illustration.
Microcontrollers are required to respond to events in the embedded system they are managing in real-time (predictable, but not necessarily quick). An interrupt system can alert the processor to stop processing the current instruction sequence in response to certain events and start an interrupt service routine, which will handle any processing that is necessary in response to the interrupt’s source, before returning to the original instruction sequence. Interrupts can also rouse a microcontroller from a low-power sleep mode, where the processor is suspended until forced to act by a peripheral event, which is crucial here because power consumption is critical, as in battery-powered devices.
