Geothermal Energy: Advantages, Disadvantages, Economics and Policy Shaharuf Islam
A slide on Geothermal Energy. Its advantages, disadvantages, the policy related to this new technology, as well as its economic values are discussed here.
Looking at the investment per effective MW, geothermal energy is a very attractive investment.
In terms of investment per MW-peak, geothermal energy seems not to be especially attractive. However, utilization must also be considered. Taking utilization into account, geothermal energy is a very attractive investment.
Finally, the period after economic life makes geothermal energy really attractive.
More than 85% of the world’s current energy needs depend on the fossil fuels. As the population of India is increasing day by day the demand for energy is also increasing exponentially. Due to the limited resources, India has to import fossil fuels which directly affect our economy. It also affects our climate by causing pollution to a great extent by producing green house gases. So due to the above factors it is necessary to ponder over the ways to implement non-renewable energies. It is in this context two emerging renewable energy resources: Biodiesel and Geothermal energy were studied and the more efficient energy resource was selected based on economic and environmental aspects.
This reports represents basic aspects about geothermal energy,

2. Literature survey
3. Sources of Geothermal Energy
4. Geothermal Energy in India
5. Conversion of Geothermal Energy into Electricity
6. Costs Related to Geothermal Energy
7. Applications of Geothermal Energy
8. Conclusion
With a new combination of existing technologies, we believe it is possible to create a renewable energy source –ultra deep EGS (Enhanced Geothermal Systems)– which is cheaper than coal.
The principle is simple: a higher temperature results in a better electricity conversion efficiency. So there is a double effect: a better conversion efficiency and the amount of available energy is higher. This double effect is stronger than the related cost of ultra deep drilling. Simple calculations demonstrate that ‘deeper is cheaper’.

Use of Nanofluids to increase the efficiency of solar panelsvarungoyal98
Experimental Investigation of the potentiality of Nanofluid in enhancing the performance of Hybrid PV/T systems. The global need for energy savings requires the usage of renewable sources in many applications. Harnessing solar energy using photovoltaic cells which converts solar radiation into electricity seems a good alternative to fossil fuels. However the heat trapped in photovoltaic cells during operation decreases the efficiency of the system. To avoid the temperature increase of the PV system we use photovoltaic-thermal hybrid solar system (Hybrid PV/T) where the unfavourable absorbed heat from the cells is collected through an additional thermal unit. Nanofluids are engineered colloidal suspensions of nanoparticles in a base fluid. Generally, the nanofluids possess greater heat transfer characteristics compared to the common fluids.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
