Well it's a huge occasion for Bengalis because Goddess Durga already arrived at her home place. But isn't it seems like there's a dark side of it too. Millions and millions of people spending money on their dresses, jewelleries and on reforming their houses but more millions out there who don't have enough money to enjoy the occasion, still wearing ripped clothes and doing their little businesses and all they expect are their respective products money but still those stupid rich brats bargaining the hell out of it and humiliating them like anything. They can spend lakhs on their houses, clothes but can't be considerate towards these needy people. Yes right now I am just disappointed in these people and in this occasion.
This House's owner denied to pay him the exact price of his product and bargained as much as she could where as she spends Lakhs every month on her house and fruits.
Image re-ranking, as an effective way to improve the results of web-based image search, has been adopted by current commercial search engines such as Bing and Google. Given a query keyword, a pool of images is first retrieved based on textual information. By asking the user to select a query image from the pool, the remaining images are re-ranked based on their visual similarities with the query image. A major challenge is that the similarities of visual features do not well correlate with images’ semantic meanings which interpret users’ search intention. Recently people proposed to match images in a semantic space which used attributes or reference classes closely related to the semantic meanings of images as basis. However, learning a universal visual semantic space to characterize highly diverse images from the web is difficult and inefficient. In this paper, we propose a novel image re-ranking framework, which automatically offline learns different semantic spaces for different query keywords. The visual features of images are projected into their related semantic spaces to get semantic signatures. At the online stage, images are re-ranked by comparing their semantic signatures obtained from the semantic space specified by the query keyword. The proposed query-specific semantic signatures significantly improve both the accuracy and efficiency of image re-ranking. The original visual features of thousands of dimensions can be projected to the semantic signatures as short as 25 dimensions. Experimental results show that 25-40 percent relative improvement has been achieved on re-ranking precisions compared with the state-of-the-art methods.
WEB-SCALE image search engines mostly use keywords as queries and rely on surrounding text to search images. They suffer from the ambiguity of query keywords, because it is hard for users to accurately describe the visual content of target images only using keywords. For example, using “apple” as a query keyword, the retrieved images belong to different categories (also called concepts in this paper), such as “red apple,” “apple logo,” and “apple laptop.”
This is the most common form of text search on the Web. Most search engines do their text query and retrieval using keywords. The keywords based searches they usually provide results from blogs or other discussion boards. The user cannot have a satisfaction with these results due to lack of trusts on blogs etc. low precision and high recall rate. In early search engine that offered disambiguation to search terms. User intention identification plays an important role in the intelligent semantic search engine.
EFFECT OF SPECIMEN GEOMETRY
The toughness, or resistance to crack growth, of a material is governed by the energy absorbed as the crack moves forward. In an extremely brittle material such as window glass, this energy is primarily just that of rupturing the chemical bonds along the crack plane. But as already mentioned, in tougher materials bond rupture plays a relatively small role in resisting crack growth, with by far the largest part of the fracture energy being associated with plastic flow near the crack tip.
A “plastic zone” is present near the crack tip within which the stresses as predicted would be above the material’s yield stress 'σY' . Since the stress cannot rise above 'σY' , the stress in this zone is 'σY' rather than that given. To a first approximation, the distance rp this zone extends along the x-axis can be found with (θ = 0) to find the distance at which the crack tip stress reduces to 'σY'
[ σy = σY = Ki/√2πrp ]
[ rp = K^2 i/2πσ^2/Y ]
This relation is illustrated. As the stress intensity in increased either by raising the imposed stress or by crack lengthening, the plastic zone size will increase as well. But the extent of plastic flow is ultimately limited by the material’s molecular or microstructural mobility, and the zone can become only so large. When the zone can grow no larger, the crack can no longer be
constrained and unstable propagation ensues. The value of Ki at which this occurs can then be considered a materials property, named Kic.

Economy after Covid-19
The world with a social biasness
BA(HONS)in Economics and politics,

For the time being, we can assume that there can be two circumstances that can affect the economy in two different ways.
● There is an antidote situation.
● There is no antidote Situation.
More or less it’s pretty hard to write any final conclusions at this moment, when too many things may be yet to happen. But the time is very much right to start any discussion on how we can see the world economy after this pandemic. There are possible consequences of the crisis, including technological shift and a change in the direction and the volumes of trade flow all around the world. I think the impact will be much worse if the situation will walk under no cure situation. However, we could call it as a socially bias economic outbreak. The year 2020 has been a disaster for both consumers and producers no matter what they produce or consume. In fact, in future, it could be more ferocious if the states do not act as a market mechanic. The future circumstances of the pandemic will leed many messages across the world about its positive effect on the environment. Despite the short period reduction in the environmental impact, over the upcoming years, we can expect huge attention for population and environmental issues. Maybe an increase in environmentally oriented costs to maintain or prevent future disasters causing a drop in the standard of living. Consumers will get more conscious about there consumption patterns. So that the world will face a step back from the basic needs as outlined in the Maslow pyramid(Maslow’s hierarchy theory). Income inequality will appear to be increasing in the future and There will be opportunities for countries to come in front with new policies, ideas, implications to build a resilient economy which is both attractive and diversified to global sectors. But meanwhile, for the global society, The economic drama yet to happen.
Border closure, pandemic related lockdowns had brought a disaster for the countries who are dependent on foreign tourist or traders. According to the IMF’s recently released 2020 External Sector Report, Costa Rica, Greece, Morocco, Portugal, and Thailand could be among the hardest hit with losses in tourism proceeds exceeding 3 per cent of GDP.
A country’s current account balance is a measure of its total transactions, which includes but is not limited to trade in goods and services with the rest of the world. For some economies, a drop in tourism (which is considered an export) could have an impact on overall current account balances. Much is still unknown about the pace of tourism recovery in 2020. Peoples’ desire and ability to travel abroad may continue to face headwinds going into 2021 due to the ongoing pandemic, leaving an uncertain outlook for tourism industries in economies both big and small.
This is an alarming crisis with several unfamiliar features that lead us a self-inflicted economic catastrophe as a necessary policy response to contain its spread. A global depression Is here and we all know only optimism won’t slow it down. I am not talking about laagers. In these modern days, the U.S. and most of the world have well built middle-class generation. We have social safety nets that didn’t exist a couple of decades ago. thankfully, that’s also true even for the most developing countries. Most governments today accept a deep economic interdependence among nations created by decades of trade and investment globalization. But those expecting a so-called V-shaped economic recovery, a scenario in which vaccine makers will conquer COVID-19 and everybody go straight back to the working life, or even a smooth and steady longer-term bounce-back like the one that followed the global financial crisis a decade ago, are going to be disappointed. Bangladesh exemplifies the triple blow that many emerging market countries have suffered from COVID19: domestic slowdown caused by the disease and the efforts to contain its spread; a sharp decline in exports, particularly in the ready-made garment sector, and a drop in remittances. Three factors separate a true economic depression from a mere recession. First, the impact is global. Second, it cuts deeper into livelihoods than any recession we’ve faced in our lifetimes And third, its bad effects will remain longer. The situation in the global economy hasn’t been the same for all the countries. A country with high interdependence between trade and self-production system with diversified sources may recover within a certain time. Although most of the developing countries are now following the capitalistic path for an exit point from this current situation. It affects all the country throughout the world including Russia, Japan, India, and almost every one of the western countries. The fault lines between globalisation and uneven development have become more apparent. The economic rivalry between the United States and China, which began a long before the pandemic, will only intensify, the centre of gravity of this rivalry will increasingly shift towards the development of new technology. This rivalry will no longer be limited to the two largest economies in the world. Any rivalry between China and its competitors will make it even more difficult for countries that are economically dependent on China or the U.S. to make their choices. It has actually revealed the vulnerability of the global value of supply chains, for the reason nations will have to prepare for the changing nature of the global economy. For the time being a set of questions are circulating around human existence. Where India and Russia have to make difficult choices regarding their future plans. How is India realising its dream of becoming a $5 trillion economy? Does Russia believe that its economy, based on natural resources, will continue to deliver the desired results at the global level? How realistic is the possibility of a fundamental shift in global economic processes as a result of a pandemic? And what does this mean for multilateral economic institutions?
A key cooking ingredient for poor & rich.

My study on onion price hike showed me an inaccurate estimate of supply and demand in Bangladesh onion market which created the Fluctuations. But, is it that easy to elaborate? Estimation of demand and production of onion wrong, the government agencies fail to understand the gravity of the problem had forced the price of this key cooking ingredient up to a record high and hurt consumers. Prices of onion hit highest of all time around Tk 250 - 300 a kg in the final days of last year. Now it seems that there is a problem in „estimates‟ or „perception‟ in the market. If the government statistics in my case study were correct, such a crisis would not have happened. So, either supply of production is over-estimated or demand is underestimated in this case.
The estimate – Government data
It says that the annual domestic demand for onions 24 lakh tonnes and 23.76 lakh tonnes were produced in fiscal 2018-19. and, 30 per cent of the produce gets wasted naturally. Based on the (GOVT) data, there was adequate stock But, this production estimate maintained by the ministry is 25% higher than the estimate of BBS the Bangladesh Bureau of Statistics, the national statistical agency. The BBS estimated that onion production was 18.03 lakh tonnes in the last fiscal year.
With that, If the annual onion import, which is nearly 10 lakh tonnes, is considered, then the discrepancy in estimate becomes very much clear. C A B said annual demand for onion would be around 30 lakh(TN).
Let’s think another way, Consumers are now getting more rational and health conscious so that they are eating more vegetable and less rice. To do so, Demand for onion is rising as people are consuming more and more vegetables by eating less rice. so the market demand is changing. That‟s why the government should revise the estimates of demand and supply of essential commodities.
“The government‟s estimate on the annual domestic demand for onion might be underestimated. The annual demand for the item might be 30-33 lakh tonnes.
It seems that they did not pay adequate attention deriving estimate of demand. They could not understand the gravity of the situation. There might be some sort of complacence among officials and they did not take the issue seriously,” Said Economist Zahid Hussain. Also fueled by the export ban slapped by India. On September 2019, India set the minimum export price to curb its shipments and help bring down soaring prices in the domestic market. Two weeks later, it announced a ban on exports with immediate effect, after extended Monsoon downpours delayed harvests and supplies shrivelled(Newspaper). Is it something new or unpredictable for Bangladesh? The answer is "no". India‟s move to restrict the export of essential commodities like an onion is not new. We had an experience regarding rice in 2008 when India restricted shipments. that caused price jumping in Bangladeshi market. And the lessons were? For faster recovery, we have to keep diversified sources open. Because when it is necessary there have to have a contingency planning in advance. So prediction in terms of balancing the market is very important. In my ongoing study of “Fluctuations in different essential commodities”, I found out that 50% of the market has been destroyed by the political business syndicates. How? Market monitoring does not mean policing. The government should assume the role of a facilitator so that adequate information flows in the market to help the market function properly. Develop a policy and maintain it. Also easing procedures for imports and exports to facilitate faster trade and measures to increase the yield of onions and developing storage facilities to reduce post-harvest loss. We have to develop our national capacity to produce our foods. We will not require imports if we could properly stock and increase yield.
What about the creation of an open database on demand and supply of essential commodities?
A hike in onion price affects the poor. I found no alternative but to monitor the onion market regularly. If Bangladeshi markets largely depended on Indian onion, the government should have followed the onion production trend in India a long time ago and taken steps accordingly. The government should forecast local cultivation and production in the coming seasons and discourage imports so that farmers do not incur losses in the event of ample supply of the perishable. But without collecting the data from the field, It can‟t be done. So, for the communication gap, Farmers hardly get into knowledge about market demand and price. This is where farmers get caught into some corrupted invisible hands.
CASE STORY – Khatunganj (Newspaper)
I have found a case at Khatunganj that describes as follows,“ Some Locals said rotten onion is being thrown away every day here. The onion had been stored by wholesalers who tried to cash in on the high demand for the common kitchen item in Bangladesh”. Onion traders believe that the crop was a little rotten when it entered Bangladesh and decomposed more after being stored in the warehouses. Lots of rotten onions were seen dumped into the canal in Firingi Bazar Bridge Ghat area. Some local youths were seen sorting out the better quality onion from there.
Some newspapers said they were selling the half-rotten onion at Tk 40-50 per kg during that period. There was some good initiative from the Government. For faster export, Taxation was taken off from the onion. This step perhaps cured the moment for a little bit. But, the power of that is something invisible and corrupted played the market. Maybe there is enough stock of onion but they are not being released to the markets. Syndicates of importers and various groups in different areas are causing an unusual hike in onion prices.
