Tri‐core photonic crystal fiber based refractive index dual sensor for salinity and temperature detection

Author: Iraj S. Amiri;  Bikash Kumar Paul;  Kawsar Ahmed;  Arafa H. Aly;  Rozalina Zakaria;  Preecha Yupapin;  Dhasarathan Vigneswaran

This article discusses the tri‐core photonic crystal microstructure fiber for the process of simultaneous sensing for salinity and temperature of water substances. This kind of microstructure is preferred in many sensing application to scale the detection process in micrometer range. In this novel sensor, the sensitivity is calculated through coupling mechanism by tracking wavelength shift of various concentrations of salinity and temperature using finite element method. The sensible samples are in liquid and are infiltrated into the framed hollow cavity. Based on the coupling principle between silica substrate and the analyte material, the sense of the salt as well as temperature is obtained. Finally, it is noted that sensitivity of the salt level in water as 5404.9 nm/RIU for x polarization direction and 5674 nm/RIU for y polarization direction have been calculated with the temperature sensitivity of 4 nm/°C in the same water substances.

Higher Education / Building Research Universities
« on: December 08, 2018, 06:04:45 PM »

It is unlikely to be contested that most of our academic institutions are not capable or equipped to do good quality research. Expecting a wide spectrum of institutions to do research is thus not likely to be fruitful. It is, therefore, time to envisage building specialized universities with emphasis on research, supported by strong graduate programs (and driven by the nation's priorities), if the Government's desire for research is to be meaningfully driven. Selectivity is very important. As flagship institutions, the “Research Universities” can play a leading role in nation building.

Daffodil International University (DIU) has achieved an unprecedented success in UI Greenmetric World University Rankings 2017. Daffodil International University ranked 1st position among Bangladeshi universities and 153 among the global context where University of Dhaka has placed the position 463 of the ranking.

A total of 619 universities based on green campus from 76 countries were brought under this ranking. Wageningen University & Research from Nethererlands ranked the top position in this ranking. The ranking was published on Monday at the official website of Universitas Indonesia (http:/   

According to the website, Universitas Indonesia is an Indonesia based organization. the ranking was prepared by based on six criteria and indicator such as Setting and Infrastructure of campus, Energy and Climate Change, Waste treatment and recycling activities, Water use in campus, Transportation system, Education in climate change etc.

Link of the Ranking:


Daffodil International University (DIU) has achieved prestigious position in QS Asia University Rankings-2019, released today on 24 October, 2018. In terms of Academic reputation criterion of the ranking, DIU as the youngest university (established in 2002) has been ranked 6th amongst all the universities of Bangladesh. DIU’s position is Just after 2 public (University of Dhaka and BUET) and 3 other Private universities.

QS Asia University Rankings is an annual publication of university rankings by Quacquarelli Symonds (QS)- a UK based organization which is the only international ranking to have received International Ranking Expert Group (IREG) approval. It is considered as one of the three most-widely recognized university rankings in the world.

This is not only a great achievement for Daffodil International University but also for the country as well. This recognition signifies DIU’s continuous commitment to implement and sustain the quality education and research at tertiary level of Bangladesh as well as quality employment of DIU graduates. By this our graduate’s employability will increase in global market.

Besides, Daffodil International University was the top ranked Bangladeshi university in the UI GreenMetric World University Rankings-2017 and was ranked 2nd in Ranking Web of Universities (Webometrics) in 2010 for web based activities and evaluation among all the public and private universities in Bangladesh.

Law / Analysing the draft Bangladesh Labour (Amendment) Act 2018
« on: September 25, 2018, 02:33:05 PM »

The draft of Bangladesh Labour (Amendment) Act, 2018 aims to make labour law worker-friendly while regulating the conduct of workers and owners in compliance with the standards of International Labour Organization (ILO). In the proposal, 2 new sections, 4 sub sections and 8 clauses have been added, 6 sub-sections have been repealed and reform in 41 sections have been proposed. After the Rana Plaza collapse, Bangladesh had to raise its standard of labour law to international standards in order to obtain the GSP plus status in the European Market. The proposed amendment attempts to fulfil these conditions by a margin.

Under this amendment, the government, after consultations with different stake-holders, has proposed to reduce the minimum support needed to form a trade union to 20 percent from 30 percent stipulated by the existing law. But the ILO Convention prescribes that even if only 10 workers want to form a trade union, they have to be granted permission. The proposed provision in this regard is not consistent with the ILO conventions. Moreover, the draft prescribes that a worker of an industry can be a member of only one trade union and in case of dual membership, the new law suggested one month imprisonment. The proposed amendment also curtails discretionary power of the Director General of the labour department in cancelling registration of a trade union. In the existing law, to form a trade union, the workers from the informal sector need identity card whereas there is no authority to provide them with one.

The proposed amendment does not bring any good news for the domestic workers who are the most neglected ones in the country. According to the proposed amendment, the government would prepare a standard operating procedure (SOP) for registration of the labour organizations. A labour organization would apply for registration in specific form and the Director General of the Labour Directorate would resolve the application within 55 days. Previously the time period was 60 days.

The draft has also incorporated tougher provisions to prohibit misconducts on the part of owners and workers. A worker or owner would get one year imprisonment or penalty of Taka 10,000 or both for any misconduct including violation of the law. The law suggested punitive actions for workers' acts that include mounting undue pressure, threat or physical assault to compel the owners to sign any agreement, disrupting power, gas or water supplies and unlawful shutdowns.

According to the proposed amendment, to organise a strike, the workers also have to notify the employers 21 days prior to the day of such event. Then the entire process of strike would require a long bureaucratic process which can definitely create a bar to legitimate strikes. In the existing law, there is provision for one year imprisonment, five thousand taka fine or both in case of participation in any illegal strike or lock-out. In the proposed amendment Act, the punishment has been decreased to 6 months imprisonment.  Under the existing law, there is a provision for a resting room. In the proposed amendment, along with a resting room, a new requirement of dining room has also been added if there are more than 25 workers in the factory.

According to proposed amendment, expectant mothers would mandatorily be entitled to get eight weeks maternity leave and other benefits within three days of submission of necessary of documents. An owner may face penalty of Taka 25,000 on charge of depriving an expectant mother from maternity leave. Under the existing law, a child can be employed for light work on condition that it would not be harmful to his health and his education would not be hampered.  The draft seeks total ban on child labour in factories. At the same time the law prohibited engagement of children and physically challenged persons in any risky job.

Smartphone / The future of smartphone tech
« on: July 09, 2018, 11:44:48 AM »
It has been a mostly boring year for smartphones. For the first time in history, smartphone sales figures across the US declined last year. Things just aren't the same anymore, with flagships touting the same features and no real substantial improvement. The ones which offer anything over your previous smartphones cost a fortune. But all is not lost. There's still hope for the smartphone industry, and here are some of the trends you might see this year.

Gaming smartphones

Up till now, Smartphones only had a few market segments for covering price ranges. But with the arrival of the Razer phone, the market changed gradually. Earlier this year, we saw the Xiaomi Blackshark and ZTE Red Magic release. ASUS has already promised the release of the ROG phone in the near future, and a plethora of accessories to support the gaming-focused smartphone. All of this has been kicked off with the release of PUBG on mobile platforms for completely free. Expect to see a lot more of these gaming smartphones arrive in the coming days.

Face recognition
Face recognition tech has been around for years, and it was expected to hit the mass market with the release of the iPhone X. We might have seen the implementation of it on the OPPO F7 and the One Plus 5T, but none of these were nearly as secure. Another patent from Samsung suggests their work on a biometric camera which uses both the iris scanner and 3D face recognition tech.

AR and VR
The current state of AR and VR is in a questionable state, yet the tech is getting cheaper day-by-day. Apple showed off its AR capability on its newest iOS update, and some other Android smartphone manufacturers have followed suit. Hopefully, we'll see a lot more AR applications throughout the next few years as AR gets more accurate and sees wider usage.

Malleable displays
The concept first started a long time ago, back in 2013 when Samsung revealed a foldable AMOLED Panel which functioned amazingly even after 100,000 bends. The project eventually took form as Samsung Galaxy X, and now it's closer than ever. And Samsung isn't the only one running this race, last year Microsoft patented a foldable display, presumably for its Surface phone. LG even patented a flexible display with a smartpen, hinting towards its attempts at catching up with the world.

New flagships around the corner
Qualcomm's newest flagships are around the corner, as just a few days ago a Japanese media site leaked an unknown Sony device getting benchmarked on Geekbench with the score being 30% higher than Qualcomm's current flagship, Snapdragon 845. Obviously, other than performance boosts, Qualcomm is expected to implement dedicated computing units for AI.

The future of connectivity
Up til now, the details about Qualcomm's upcoming flagship SoC, Snapdragon 855, has been scarce. We know that it's supposedly a 7nm chip and possibly manufactured by TSMC. It's a smaller chip than the 845, so we can expect some power efficiency from this brand-new chipset. Qualcomm is more interested in pushing its X50 modem supposedly bundled with the 855. In late 2017, Qualcomm announced a successful trial of their X50 modem supposedly running 5G connections. This hints that future flagships might feature 5G modem, and Qualcomm might be powering the first batch.

Mobile payment
Mobile payment sees a wider application with Android Pay and Samsung Pay getting used across the world. It's hard to say which one's faster to win the race, but Samsung Pay's winning for now with its Magnetic Secure Transmission tech, supposedly supported by around 90% of all US retailers. As NFC becomes the norm, mobile payment is sure to get more secure. Who knows, maybe Google might decide to buy one of our own mobile banking giants.

Wireless charging will be widespread
A few days ago, famous Youtuber LinusTech Tips featured a wireless charging module which charges out of thin air in a selected area. This device also should charge smartphones relatively faster- which is surprising. Probably not far off before you see this device in a Starbucks store as manufacturers start racing to support this tech.

The bezels are dead
2017 was the year of the notch, and that trend has watered down to mid-level smartphones in 2018. Needless to say, it was time to innovate. As so, Smartphone giants OPPO and Vivo decided to release their own take on the bezel-less competition. Samsung and Apple failed to be the first one to remove bezels completely, however, as Vivo Apex was the first phone with seemingly no bezel. This is a sign of things to come, as with the death of bezels, virtual buttons are slowly becoming the norm.

Under display fingerprint scanner
We've already seen this tech pouring in, but it'll be even faster. First seen in the X20 from Vivo, major players such as HTC, Apple, Samsung or Xiaomi are yet to introduce the feature in their phones. But we presume that under-display fingerprint reading is the future, as it's getting faster day-by-day. And it's a change we all want because fingerprint scanners on the back or front do play a role in the aesthetics of the device.
