Thiman T. Dulsara Kumarage’s final year dissertation for his BSc. (Hons.) Software Engineering degree at ICBT Colombo, awarded by Cardiff Metropolitan University, tackles three modern-day problems with the development of an IoT (Internet of Things) based smart locker system. The Island met Kumarage, who is also an undergraduate at Plymouth University (NSBM), parallelly following a BSc. (Hons.) Computer Security, to talk at length about his latest project.”
Q: What are the problems you are trying to solve?
A: Of the three major problems, one concerned the Last Mile Delivery [Last mile delivery is defined as the movement of goods from a transportation hub to the final delivery destination. The final delivery destination is typically a personal residence; another contactless parcel exchange, and finally, the short-term rental key exchange problem.
Regarding the last mile delivery, according to multiple studies, most door-to-door delivery companies incur over 50 percent of their total delivery costs during the final door-to-door delivery efforts. Having to go door-to-door with multiple parcels while doing redeliveries for missed attempts, these companies need to maintain a large number of delivery personnel and vehicles.
Furthermore, fuel costs, maintenance of vehicles, insurance for vehicles and staff against accidents and domestic issues such as dog bites at delivery points heavily increase the costs they must incur, which they do by passing it down to the customer as well. From a customer perspective, door-to-door deliveries can sometimes be highly inconvenient, especially for people who work away from home. Many often find themselves having to take time off work to be home to collect parcels on delivery dates, or make other arrangements such as troubling friends, family or neighbours to collect on their behalf as they know the alternative is risking porch piracy [porch piracy refers to a situation in which an individual steals a package from a porch or other area near the main entrance of a residence before the recipient can retrieve it] or missed delivery, in which case they must go to a distant office to collect their parcel.
Contactless parcel exchange is yet another modern-day problem. Due to the very busy schedules we all run, when a requirement to exchange parcels with friends or family arises, we often struggle to find a common timeslot when both parties are free to engage in the exchange, causing one of the parties to go out of their way to make time to adjust to the other’s schedule.
Finally, concerning the short-term rental key exchange problem; in modern times we often book apartments and other accommodation options online, such as on Airbnb and Agoda. However, the actual key exchange between the landlord and the rentee still requires physical contact. Given that the amount of money that can be made renting property short-term is much higher than long-term rentals, this is a major incentive for landlords. However, given that landlords often must rush or wait to exchange keys with the rentees, the cleaning crews or maintenance crews, making this an active income stream which requires a lot of time commitment; many landlords opt for the passive income path of long-term rentals, even at lower rates. Although some landlords trust security or cleaning personnel to do the key exchange for them, there had been many cases where such staff had illegally rented apartments without the landlord’s consent, even for illegal activities.
These were the three primary issues I was trying to address in my project.
Q: How does your solution resolve the problem?
A: The project proposes an IoT-based smart automated locker system. It proposes a system in which such lockers would be located in public places similar to ATMs. A person could come to the locker, place an item and provide the details of the intended recipient. Once the item is stored and locked, the recipient is automatically informed, via text and email, of the package waiting them, along with the details for the locker, and the password (key) with which to retrieve it. It is in essence like a locker that you can lock an item in, and virtually send the key to the recipient with which to unlock it.
When it comes to the last mile delivery issue, delivery personnel can deliver missed deliveries to the nearest automated locker, drastically increasing their delivery efficiency by not having to attempt redeliveries. From a customer’s perspective, they could choose to get their items delivered to these lockers rather than their homes, so they don’t need to cancel their plans to stay home to collect parcels or risk porch piracy. Once delivered to the locker, the recipient can simply collect their parcels from the locker on their way home from work. When more and more customers opt to get items delivered to the lockers, the number of door-to-door deliveries drop, which can lead to a drastic reduction in delivery costs, which benefits both the companies and customers.
The same logic applies for contactless parcel delivery. When it comes to the key exchange problem, this offers many benefits, ranging from making short-term rental services a passive operation, encouraging more landlords to engage in this form of rentals, to reducing rental cost dispute issues, as the locker can maintain a log of exactly when the keys were collected and returned, as short-term rental fees are often paid for set periods of hours.
Q: Is this a novel solution?
A: Although it’s not available in Sri Lanka, similar systems are very popular aboard as a way of addressing last-mile delivery issues. However, this concept hasn’t been specifically used for key exchange by any major service provider.
Q: Is there any difference between this project and the current systems available abroad?
A: The primary shortcoming of the lockers used in foreign countries is that it has led to many disputes with delivery companies over stolen deliveries. Delivery personnel often falsely claim that they have delivered items by simply opening and closing empty lockers without placing any item inside, stealing the items. The recipient gets the alert of the delivery as intended. However, when they open the locker, they find it empty. Given that the dispute process with delivery companies is often lengthy, customers typically don’t waste time on disputes, but contact the seller direct and request refunds for the stolen goods.
This had also led to other unintended risks, such as dishonest customers who collect parcels from lockers before falsely requesting refunds from sellers claiming they were stolen. Due to this being such a major issue in foreign countries, many sellers refuse to offer delivery options to these automated lockers. A concept filled with potential has hit a roadblock due to this lack of confidence.
In the proposed solution, I have proposed to place load/weight sensors in all compartments. When a delivery is made, the locker logs the time of delivery, and once the locker door is closed, it also measures its weight. This information is then included in the message sent to the customer and delivery company. This in essence, provides irrefutable evidence to all parties if a dispute is to ever occur. This also addresses the vital need for confidence in the system.
Q: What research have you undertaken to justify the proposal?
A: As a part of the research conducted to gather international data through secondary sources for the project, I have undertaken data collection and analysis of multiple peer-reviewed research papers and journals. Furthermore, I have interviewed a number of delivery personnel in both Sri Lanka and abroad where such locker systems exist, as well as landlords with short-term rentals to get an in-depth understanding of the variables and influences concerned. In addition, I have personally experienced such delivery disputes during my time abroad.
Q: What are the deliverables of
A: At the conclusion of the project, I’ve been able to produce a proof-of-concept smart-locker, powered by a Raspberry Pi 4 and an Atmel microcontroller, controlled by a custom-made software for the locker, and an android mobile application for the end user. The deliverables were strictly designed for closed-testing and proof-of-concept purposes, to assess the feasibility of the technology.
Q: Have you undertaken any other similar projects?
A: I have both directly undertaken or have been involved in multiple IoT based projects, as the primary overall systems designer, including highlight projects such as a ‘human-elephant cohabitation’ (HackaDev) project which proposed a new take on human-elephant conflicts, and a Web and Mobile controlled smart home solution project which allows users to use low-cost non-smart appliances such as normal lights or fans along with smart-home features.
Thiman Kumarage wishes to thank lecturer, Induneth De Silva, and his supervisor, Vindya Karunarathne, for their kind guidance throughout the project. He is grateful to the management and staff of Alucare (Pvt.) Ltd. and SilverReed Advertising Services (Pvt.) Ltd. for their kind assistance in helping him build the physical structure of the locker system according to his specifications. He thanks his parents for all the mental and financial support to make all his projects a reality.
A legend who rewrote Sri Lankan history: Eulogy for Dr. Deraniyagala
By Tharindu Muthukumarana
(Tharindu Muthukumarana Author of the award-winning book “The Life of Last Proboscideans: Elephants” firstname.lastname@example.org)
On Tuesday, 05 October, 2021, as the sun rose above the horizon it may have felt like a usual day in Sri Lanka. But the morning broke a tragic news as it gloomed the nation and it left a deep void in the field of archeology. It was for none other than to the demise of Dr. Siran Upendra Deraniyagala.Anyone who has an interest in the history of Sri Lanka doesn’t need an introduction to Deraniyagala and his service. I find him, that rather than investing his energy on archaeology he invested his soul. This set an example for every human to work hard with integrity on what you had embarked on.
Budding of an archaeologist along with his father
When thinking about Paleoanthropology in Africa the renowned Leakey family comes to our head where the parents and their children had done remarkable research in that criterion. If that so, in Asia it would be the Deraniyagala lineage that had the astounding research on Paleoanthropology.
On 1st March,1942, Siran Deraniyagala was born in Ratnapura as the third son of parents, Dr. P.E.P Deraniyagala and Prini Molamure. His grandfather was Sir Paul Edward Pieris Deraniyagala alias, Sir Paul E. Pieris who served as a District Judge in Matara, Kegalle, Kandy and Kalutara. Though Sir Pieris was professionally linked to the legal field, he had a passion on doing research on 16th -19th century history in Sri Lanka and made notable publications related to those. His work was well reputed that he received various awards and honours from western countries including the Knight Bachelor on Queen’s Birthday Honours 1952.
Siran’s father, Dr. P.E.P Deraniyagala was a zoologist who also specialied in paleontology. After the brief discoveries in 19th -20th century on paleolithic remains by Paul Sarasin, Fritz Sarasin, Charles Hartley and Edward James Wayland, it was Dr. P.E.P Deraniyagala that did intense research on the paleontology of Sri Lanka. It was his research that opened the door to the prehistoric chapter in Sri Lanka. Young Siran used to accommodate on his father’s research expeditions which inspired the youngster to follow his father’s footsteps.
As a passionate youth after completing his education at S. Thomas’ College, Mount Lavinia, he was admitted to the University of Cambridge, where he obtained a BA and MA in Architecture and Sanskrit. He completed a postgraduate diploma at the Institute of Archaeology, University of London. He passed with distinction and was awarded the Gordon Childe Prize.
Sri Lankan statesman the late. Lakshman Kadirgamar once said in his speech at the Oxford Union, describing himself, that “Oxford was the icing on the cake… but the cake was backed at home”- referring to Sri Lanka. I think this quote also applies to Deraniyagala as well, since his first experience with archeology is linked with his father’s expeditions prior to university education.
Embarking on great expeditions
Deraniyagala joined the Archaeological Department in 1968 as Assistant Commissioner in charge of excavations. His functioning in the latter capacity was primarily research-oriented with emphasis on Sri Lanka’s prehistoric period (beyond 1000 BC) while pioneering in its protohistoric (1000-500 BC) and early historic (500 BC-300 AD) archaeology as well. The substance of his contribution to knowledge is set out in the abstract to his PhD at Harvard University in 1988. Doctoral dissertation was based on his research excavation in ancient shore dunes at Iranamadu Formation which trace back to more than 130,000 years ago. The thesis has been hailed as a landmark in the archeology of South Asia, and it has transformed Sri Lankan prehistoric studies. In later time he was awarded with honoris causa doctorates from Sabaragamuwa and Peradeniya Universities.
He was well known for research on Anuradhapura citadel and at Fa Hien cave. Deraniyagala’s work continued as Adviser in Research Excavtions (1983-92) and as Deputy Director-General and the Director-General (1992-2001) to Archaeological Department. Deraniyagala’s position as the Director General marked a milestone in the Archeology Department, which it was the only time where father and son had served that position. Even after retirement Deraniyagala never gave up his work-related to archeology; instead, he did continue and at most time he had a busy schedule.
Over his lifetime, he had been awarded with many local and international awards. On 7th September 2020 the Department of Archaeology opened its research and teaching museum named after Siran Deraniyagala.
Transparency on research
Research involves molding facts out of observations. It is a common thing that some facts that are composed get subjected to criticism. This could be due to various reasons. In 1988 Deraniyagala found potsherds belonging to 600-500 BC with Brahmi inscriptions. Many foreign experts did not believe it because it was known at that time Brahmi inscriptions were absent before the Asokan period (268-232 BC). Deraniyagala invited experts from Cambridge University to come and study the excavation site to check whether he was wrong. As those foreign experts came and researched on that site, even they later agreed on Deraniyagala’s theory. Similar incident happened at Kuruwita Batatotalena Cave excavation by Deraniyagala.
These events signify Lord Buddha’s quote: “Be your own lamp, seek no other refuge but yourself, let truth be your light”.
Farewell of the legend
It is eye-opening to notice that just one day after the 49th death anniversary (October 4th) of Prof. Senarath Paranavithana, Dr. Siran Deraniyagala passed away. He was 79 years old at the time. His funeral was held at his residence “Ekneligoda Walauwwa” on 10/6/2021. The President’s condolence message was read by the Governor of Sabaragamuwa Province Tikiri Kobbekaduwa.
Initially Sri Lankans were mostly proud of their 2,500 years old history but thanks to Siran Deraniyagala and his father a 38,000 years old history got unveiled.
Dr. Siran Deraniyagala, Sir may you attain the supreme bliss of Nirvana!
Hope that lies in the Pandora Box
The Pandora Papers have moved away from the focus of politics and the fight against corruption.
We can await the report of the Bribery and Corruption Commission, which has its own way of giving innocence to the guilty; much more than the fighters against corruption ever expect. But that is the stuff of Saubhagya.
The Pandora Papers (PP) have also shown the great delight of Nirupama Rajapaksa – Nadesan, in settling down with her children in London. That is just one big success story of the PP. There will be much more success to follow from the PP, with the Rajapaksa politics moving on to bigger dominance in this Siri Lankava, running in circles of disaster to find foreign exchange, despite the big promises of the Central Bank’s Nivard Cabraal.
It was far away from the PP that President Gotabaya Rajapaksa admitted with courage, of his and the government’s failure to keep up with the promises given to the people and the country. His words at an important military ceremony, where he was proudly draped in a civilian suit, and played some cricket, too, were rich with reality. It was not only him, but all Ministers and Members of Parliament that should accept this failure, he said.
Those words were the stuff of a President, who after nearly two years in office and power, decided to tell the people of the realities of governance.
What these words revealed were not the stuff of the PP. but the very stuff of the Pandora Box. It was the box from which all the evil flew out, when opened by Pandora herself. The President and the Government are certainly the victims today of the Pandora Evil, which is far beyond the great expectations of the Saubhagye Dekma.
The government is just now in a great Pandora Dance. With the removal of all gazette notifications on the price of essentials, it is certainly free of the burdens of price control and support for the people. This began with the new prices of rice. It is not a Gotabaya achievement, but an achievement of Dudley Sirisena and the Rice Mafia.
The Pandora Box has much more to follow. It is the box of business, merchants and dealers – who may be the mafia, too. Surely, what government would raise the price of gas used in domestic cooking by more than a thousand rupees? It is the stuff of the Pandora Mafia. Just watch out, it can even rise by another thousand rupees very soon — could this be the Gammanpila Pandora Player?
Did Saubhagya Governance ever want to raise the price of bread? What nonsense. The government – ministers and MPs want to keep it down. But the evil that flowed from the Pandora Box made it rise. Who was the Pandora Bread/Flour minister?
Not only bread, milk powder, too. Would any MP, Minister or even a President, want to raise the price of powdered milk, which is part of a child’s daily diet? Never. This price increase is also the work of the Pandora Box – Kiri Piti – Mafia, which is much more powerful than the mafia of political corruption.
All this is certainly far away from the promises that candidate Gotabaya Rajapaksa, and the other Rajapaksas, too, gave to the people before the presidential and general elections. They never thought that the evil of the Pandora Box would hunt them so well.
To go back to the Pandora story of Greek legend, there is still hope for us. While all the evil from the Pandora Box had escaped before it was closed, Hope still remained trapped in the box. That is the Hope that is left for the Sri Lanka people.
Let us not allow this Hope to be trapped in a box at the Rajavasala. We can be glad about Gotabaya’s admission of failure. But our larger Hope will be in a political escape from the wider Rajapaksa governance — moving next from Basil to Namal. Let’s keep praying for the escape of Pandora Hope for us. Even a little hope can help us a long way!
Cops, criminals, and cultural contours
By Uditha Devapriya
In Michael Mann’s Heat, one of the best heist thrillers ever made, the protagonist is a cop called Hanna, played by Al Pacino. The other character, a thief called McCauley, is played by Robert de Niro. Hanna and McCauley meet for the first time at the end of the first half of the movie. Hanna, who works for the LAPD, has been investigating a series of high-profile crimes for days. He guesses McCauley is the culprit, but has no real proof.
Convinced that he is the man they are looking for, Hanna tails him one night and gets him to pull over. Instead of arresting him, though, he offers to buy McCauley coffee. They then go over to a diner, where the two of them sit in front of each other.
What unfolds thereafter is not a conversation, but a charade. The detective and the thief start talking at cross-purposes. Weary, numbed, and tempered by the weight of their work, they engage in casual banter. Like countless conversations from a Jean-Luc Godard film, this doesn’t make sense; they ramble on and on, and then suddenly stop.
It is when we step back and reflect on these two that we realise what the scene is trying to tell us: the detective has come to a point in his career where he depends on the thieves he tails. It’s the same story with the other guy: he’s been involved in so many crimes that he’s almost relieved to talk to a man of the law. Their meeting is thus marked out less by hostility than by empathy. It’s a meeting of the minds.
The face-off is intriguing to me because it reminds me of a similar conversation from a film made 25 years earlier, in Sri Lanka. D. B. Nihalsinghe’s Welikathara also pits a police-officer against a criminal, this time a drug kingpin. In the scene I am talking about, that officer, like Al Pacino’s detective, encounters the kingpin in full form at his office. By this point each of them has realised what the other wants: like the lawyer and his ex-client in Cape Fear, each knows only too well that the other is seeking the upper hand.
The sequence at the police station establishes this relationship. As one salty witticism gives way to another, we sense the revulsion underlying the conversation; the two are talking at cross-purposes, only barely concealing their contempt for each other.
Yet while the scene serves a different function from the diner episode in Heat – whereas the latter sequence shows how dependent the cop has become on the thief, here it reveals the hostility between the two men – it stands out almost like the other does. That has much to do, I think, with the acting: neither Al Pacino nor Robert de Niro had made much of a name for themselves when Welikathara came out, but seeing Gamini Fonseka play the cop and Joe Abeywickrama the criminal, you do tend to compare. To make such a comparison is to acknowledge that Welikathara represented a high point for our cinema.
may well be the most Americanised Sinhala film ever made. Whereas most Sinhala films had been distinctly continental until then, hardly any director had ventured into Hollywood territory. What makes Nihalsinghe’s film fascinating, in that sense, is how far he conceived its story along the lines of a typical American thriller.
My interest in the movie as a critic, however, has less to do with its cinematic merit than the spotlight it throws on an era when such cosmopolitan objets d’art were more the norm than the exception. Since this year marks the 50th anniversary of Nihalsinghe’s film, I felt it apt to ponder why, from achieving such heights then, we have slid down so badly now.
Perhaps it’s best that we restate the problem: how could the kind of acting exemplified in a movie like Heat become the norm there today, whereas the sort exemplified in Welikathara has turned out to be the dismal exception here? I am not just suggesting that our art forms have deteriorated in quality – though this is exactly what has happened – but that there are many reasons that can explain such a decline. Where have our arts gone? Why hasn’t it still realised its potential? What can revive it? Who can revive it?
The importance of these questions cannot be emphasised enough. A society’s popular culture is a fairly accurate gauge of its intellectual achievements. It is true that this remains a function of economic position; hence rich countries have more potential for high cultural achievements, whereas poorer countries do not. Yet that is not necessarily the case all the time: the Indian film industry, to give one example, is considerably more diverse, and much richer, than its counterparts in countries like Singapore.
India is a case in point for the view that the greater the size of the population, the more sophisticated a country’s popular culture will be. But that also is not always the case: as the recent resurgence in African cinema shows, a big population does not in itself contribute to the upliftment of a culture to the exclusion of more pertinent factors.
This is not to say that issues of economic development or population are secondary to those other factors. Affluent countries can afford superior works of art, while poorer countries (of which India is a prime example) are able to do so with a public that patronises commercial works of art, which helps subsidise more serious ventures. In that sense, the US enjoys the twin advantage of a powerful economy and a large audience.
But to acknowledge these points is not to deny the relevance of other reasons for the growth or decline of artistic standards. In Sri Lanka’s case, any attempt at diagnosing the problems of its culture must hence start from an appraisal of the post-1980 decline in the arts: a phenomenon reducible to neither economics nor demographics.
Three schools of thought have attempted to explain this decline. The first school views 1956 as the reason: by empowering everyone to enter our schools and universities, so their logic goes, cultural and artistic standards were compromised. That is another way of saying that if schools and universities remained shut to poorer classes, those standards would have been protected and fostered by an elite minority.
The second school argues that with the advent of economic liberalisation in 1978, the government’s hold over artistic quality was loosened, thereby debasing cultural yardsticks, transforming lowbrow into middlebrow art, and raising the latter to the status of highbrow art. To invert Marx’s dictum, what was once profane now became sacred.
I personally think this argument holds more water than the first – not least because the first school tries to frame 1956 as avoidable, which it was not, and fails to distinguish between its progressive and regressive aspects, which should not be done – but it does not explain a point the third school dwells on: the debasement of our education system because of, and paradoxically in spite of, various reforms enacted after 1956.
This is where the line between the progressive and regressive aspects of what transpired that year must be drawn: though there was a need to democratise schools and universities and they were democratised, barring crucial reforms in the second Sirimavo Bandaranaike government (pioneered by a set of brilliant educationists and scholars like Neil Kuruppu and Douglas Walatara) no attempts were made to maintain quality in them.
The results are there for all to see today: while certain schools and universities produce better thinkers than others, one does not come across such thinkers as often as one would want. That these trends have spilled over to the performing arts is a no-brainer: we don’t produce original artists too often either. “Manike Mage Hithe” offers the promise of what Sri Lanka’s popular culture should be, but such ventures are rare.
The third school consolidates the arguments of the first and the second: it acknowledges concerns over the negative aftershocks of 1956, as the first school does, while tracing the trajectory of cultural decline to the period after 1980, when the abandonment of the United Front education reforms multiplied those aftershocks, as the second school does.
Any critique of the country’s less than brilliant cultural scene today should take into account these factors when proposing viable solutions. In particular, it should identify exactly quality has come down and how best we can go about improving it.
It is fashionable to say that Sri Lanka’s cultural standards remained high until 1956. To me though, this is a deeply fallacious argument: a comprador society, which is what prevailed before 1956, does not produce a genuine culture. A culture must dig deep in search of roots. The problem is not that such a search stunted artistic development in the country, as those who idealise the pre-1956 status quo think, but rather that it did not go deep enough. That paved way for a massive flaw in our education system: the delinking of the performing arts from their literary roots, slowly since 1956 and more rapidly since 1980.
What I am arguing here is that as actors, directors, and even scriptwriters, we don’t read as much as we used to. In saying that, I am not denying there are other problems we have to look into with respect to Sri Lanka’s popular culture. But as the central issue, this problem requires immediate resolution. The sooner we realise our priorities there, the sooner we will be able to address a deplorable, though no less reversible, decline in artistic standards. All it takes to confirm the reality of such a decline, of course, is to see Welikathara, see Heat, and then ask why we used to have it so good, and how far back we have fallen today.
