Statistical Modeling and Optimization of Biodiesel Production from Azadiracht...IJAEMSJORNAL
In this work, statistical modeling and optimization of biodiesel production from Azadirachta Indica(neem) using co-solvent technique via a two-step transesterification process was carried out. Neem oil was extracted from neem seeds and properties such as moisture content, specific gravity, acid value, saponification value and iodine value were determined. The experimental design used was Central Composite Design. The range of factor levels used for the Central Composite Design were reaction temperature (30°C to 46°C), catalyst amount (0.8% to 1.2%, w/w), reaction time (20 to 40min) and methanol-to-oil molar ratio (5:1 to 9:1). The co-solvents used were methanol and diethyl ether. The co-solvent-to-methanol volume ratio for all the experimental runs was kept constant at 1:1. Also the biodiesel produced was characterized for some important properties including acid value, specific gravity, saponification value, iodine value, cetane number, ester value, kinematic viscosity, flash point, pour point and cloud point. Optimized biodiesel yield of 84.77% was obtained for reaction time of 35 min, catalyst amount of 1.10g, reaction temperature of 34°C, and oil-to-methanol molar ratio of 6:1. The cetane number (51.733), specific gravity (0.8881g/cm3), flash point (134oC) and kinematic viscosity (5.86mm2/s) of the produced biodiesel met the ASTM specifications. The results of characterization of the biodiesel revealed that biodiesel can be produced at lower reaction conditions and with comparable fuel property with biodiesel produced using conventional methods.

Abstract The experimental investigation was made to estimate the performance of methyl esters of Canola waste cooking oil and their blends in a direct injection diesel engine. The Canola waste cooking oil methyl ester (CWCOME) was prepared through transesterification process by using methanol and KOH as a catalyst. The Canola biodiesel blends were ready in proportion of 10%, 20%, 30% and 100% of biodiesel with diesel. The effects of pure biodiesel and their blends on engine performance, and exhaust emission were studied under various loading conditions. The experimental results concluded that up to 20% of methyl esters did not affect the performance parameter like fuel consumption rate and brake thermal efficiency. On the other hand above CB20 (20% Canola biodiesel with 80% diesel) a decrease in performance and combustion parameter were clearly observed form the study. Keywords: Canola waste cooking oil, Canola methyl ester, Transesterification, Internal combustion engine, Engine performance.
Production of Biodiesel from Waste Cooking Oil By Co-Solvent Method.IRJESJOURNAL
Abstract:- Biodiesel is a mixture of mono-alkyl esters of long chain fatty acids derived from a renewable lipid feedstock. It can be used as an alternative fuel as the fossil fuels are getting depleted day by day. Moreover the use of biodiesel leads to the substantial reduction in the pollution caused by PM, HC, CO etc. This paper consists of the production of biodiesel from waste cooking oil using alkaline catalysts NAOH and KOH and cosolvent acetone in the presence of methanol. Waste cooking oil is used because of its high oil content and abundant availability. This method used is co-solvent method.

Due to increase demand of energy, increasing price
of petroleum fuels, depletion of petroleum fuels, and
environmental pollution by these fuel emissions, it is very
necessary to find the alternative fuels. This work focused on use
of hybrid blends of Karanja and Cottonseed oil Biodiesels. In this
work 20% and 25% blends are used and the performance and
emission tests were conducted on single cylinder, 4-stroke, water
cooled CI engine by running the engine at a speed of 1500rpm, at
a compression ratio of 16.5:1 and at an injection pressure of
205bar and performance parameters like BP, BSFC, BTE and
the emissions like CO, HC and NOx are compared. It was found
that the blends gave comparatively good results in respect of
performance and emissions.

Biodiesel Production from waste Oil with Micro-Scale Biodiesel System Under L...IJERDJOURNAL
ABSTRACT:- The aim of this project is to produce biodiesel from waste oil. The use of vegetable oils as diesel fuel started with the invention of diesel engines in the 1900s and is also common in many countries today. The fact that the oils used in biodiesel production are also an important input of the food industry is a limiting factor in production. For this reason, it is aimed to produce biodiesel from waste oil which can not be assessed in food production in this study. The most important contribution of the study to biodiesel researches is the establishment of a small-capacity biodiesel unit in laboratory conditions. The waste oils from the food production facilities of Namık Kemal University (NKU) have been collected and biodiesel has been produced using two different experimental methods. The analyses that determine the quality of the biodiesel samples have been carried out by Energy Agriculture Research Center of Black Sea Agricultural Research Institute in Republic of Turkey Ministry of Food, Agriculture and Livestock. As a result of the research, it has been determined that the biodiesel fuel obtained by the B-1 method using KOH as a catalyst conforms to the standards and can be used with confidence in diesel engines.

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.
