This document discusses selecting a ballast water treatment plant for a 17500 DWT Pertamina tanker. It outlines regulations from the International Convention for the Control and Management of Ships' Ballast Water and Sediments for limiting organisms discharged from ballast water. It then compares several ballast water treatment technologies and manufacturers based on power requirements, maintenance and installation costs. ERMA FIRST SA ballast water treatment is selected for the tanker due to its relatively low costs and effective hydrocyclone filtration system that does not require chemicals.

Relevancy and Search Quality Analysis - By Mark David and Avi Rappoport
The Manifold Path to Search Quality
To achieve accurate search results, we must come to an understanding of the three pillars involved.
1. Understand your data
2. Understand your customers’ intent
3. Understand your search engine
The first path passes through Data Analysis and Text Processing.
The second passes through Query Processing, Log Analysis, and Result Presentation.
Everything learned from those explorations feeds into the final path of Relevancy Ranking.
Search quality is focused on end users finding what they want -- technical relevance is sometimes irrelevant! Working with the short head (very frequent queries) has the most return on investment for improving the search experience, tuning the results, for example, to emphasize recent documents or de-emphasize archive documents, near-duplicate detection, exposing diverse results in ambiguous situations, using synonyms, and guiding search via best bets and auto-suggest. Long-tail analysis can reveal user intent by detecting patterns, discovering related terms, and identifying the most fruitful results by aggregated behavior. all this feeds back into the regression testing, which provides reliable metrics to evaluate the changes.
By merging these insights, you can improve the quality of the search overall, in a scalable and maintainable fashion.
Premier Tech Aqua is quite excited to meet with you and present its offer in answer to the significant changes of the Ontario Building Code that came into effect last January 1, 2017. Fully certified CAN/BNQ, Ecoflo Biofilter now integrates coco chips in its organic filtering media and offers 2 options, demand and time-dosed to provide more design flexibility, both at a highly competitive pricing. Ecoflo Biofilter remains as simple as ever to design and install and ensures a performance that exceeds the new requirements.
Topics of Discussion:
- New CAN/BNQ Regulations and impact on our industry
- New Ecoflo Biofilter – the most ecological and simple septic system of the industry
- Maintenance Update
- Nitrogen reducing option
- Phosphorus removal option
Over the years Cooling Tower treatment involves heavy use of chemicals. Unfortunately these chemicals are not only costly, but also adds minerals in the water. This reduces Cycles Of Concentration [COC] & as a result in high blow down & more make up water demand. Using ozone operating cost is drastically reduced & blow down water quantity also reduces.
Renewable Energy - Wind, Hydro, Solar - are technologies that we feel good about. The environment needs it and we need it. However, there are challenges to the reliability and economy of these technologies that must be met. Discover how oil analysis and contamination control can improve reliability and extend life of critical components.

Water Treatment Plant Design by Damora, Waite, Yu, MaroofianJonathan Damora
Water treatment plant design group project with Alex Waite, Jenny Yu, Cyrus Maroofian, and Jonathan Damora. We chose the reliability of a turnkey solution by General Electric for our Reverse Osmosis and nanofiltration, while designing our own granular media filter. The focus of this project was to design a reliable system, which will perform at required standards no matter the influent composition.
The demand of power is increasing exponentially results in installation of new stations whereas the sources of water are depreciating acutely. In future there may be a situation in which water sources may not cope up with this requirement.
Also the serious concerns of the regulatory authorities regarding usage of natural resources, definitely the norms will be further be tightened, which will curtail the freedom of usage of water in power plant.
In present scenario land acquisition is one of the toughest hurdles in plant installations which can be averted by locating stations in water scarce regions, by employing air cooled system which eliminates dependencies on water for CW.
Although dry cooling systems are costly technologies on techno-economic considerations, but foreseeing the future it is the need of hour to employ dry cooling system which offers possible solution for power plant installation eliminating the above mentioned challenges.

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.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
