Experimental evaluation of performance of electrical discharge machining of d...eSAT Journals
Abstract Electrical discharge machining is the most widely used machining process in industries. Its use is particularly intense when very complex shapes on hard materials with a high dimensional accuracy are required. However the technological capability of the process has limited application when there is a requirement of high surface quality and mirror like characteristics. Its operation is characterized by long machining time, high tool wear and uncertainty in the final finish of the surface. However for finish surface, materials are subjected to mechanical polishing after EDM, which is wastage of time and energy. To improve the efficiency and surface finish of the work piece, the abrasive particles of Aluminum oxide (Al2O3 ) are mixed into the dielectric fluid at tool-work interface. In this Abrasive mixed EDM, the Abrasive mixed dielectric fluid facilitate the bridging effect and minimize the insulating strength of the dielectric fluid. As a result it improves the material removal rate and surface roughness. This paper presents the effect of abrasive on the performance of the EDM process. The results of both the processes have been analyzed using Design of experiments to find the significant parameters and to obtain the optimum parameters required for machining. Analyzed results indicate that abrasive particle size and abrasive concentration and pulse current are the most significant parameters that improve the material removal rate in comparison with traditional EDM. A new experimental setup is developed for experimentation. The result shows that the MRR increases with the abrasive mixed EDM. Keywords: Material removal rate, Abrasive mixed EDM, Dielectric fluid, Design of experiment, Abrasive particle size.
The big challenge of the mass production firms is concentrated for achieving high quality
products with good dimensionability with high productivity, less wear on the cutting insert, less use
of cutting fluid, within less time. This paper present dissertation work of an investigation of turning
process parameters on hard EN 31 material, for optimization of surface roughness, material removal
rate, machining time in wet and minimum quantity lubrication system. The experiment is carried out
by considering four controllable input variables namely cutting speed, feed rate, depth of cut and
insert nose radius in the presence of wet & MQL system. This experiment also present the relation
between chip formations and controllable variables along with chip thickness, chip colors & chip
velocity from which its effect on insert wear, quality of product can be easily found out, because of
chip morphology gives indirectly the effect of it on the insert wear. In this dissertation work
minimum quantity lubrication system is used for reducing the cutting zone temperature properly and
very fastly. Finally comparison is carried out between wet and minimum quantity lubrication system
from which one can easily identify which system is better for higher productivity along with high
surface finish. This work also present the productivity (MRR) concept in production. The design of
experiment and optimization of surface roughness, material removal rate, machining time is carried
out by using response surface methodology (RSM). Central composite design method is used (CCD)
for the total experimental design work and its analysis and also for optimization of turning process
parameter by which wastage of the machining time, power can be avoided.

Effect of granulated blast furnace slag as substitute for fine aggregate in c...eSAT Journals
Abstract
The objective of present investigation was to study the effect of granulated blast furnace slag as substitute for fine aggregate in cement mortar and concrete. Now a days, river sand becomes scarce and costly too, which is one of the very important ingredient of concrete and cement mortar mix especially in India and the world consumption of sand in concrete generation along is around 1000 to 1100 million tonnes per year, making its scarce and limited. Shortage of river sand resulted into the over dredging of river sand which causes environmental threat and loss of aquatic life also. In this paper granulated blast furnace slag is used as substitute for river sand in cement mortar and concrete, to overcome the environmental problems created due to over mining. In this investigation, in a cement mortar and concrete replacing natural sand by granulated blast furnace slag in a range of 20%, 40%, 60%,80% and 100%. The workability and strength of cement mortar and concrete with varying percentage of granulated blast furnace slag substitute which is then compare with workability and strength of conventional concrete. To determine the workability and strength of cement mortar and concrete, cubes of standard sizes 150mm x 150mm x 150mm (for concrete) and 70mm x 70mm x 70mm (for cement mortar) for 3rdday (cement mortar), 7th day and 28th days were casted and tested under compression testing machine . The work is extending to 100% replacement of natural sand with granulated blast furnace slag for M-20 grade of concrete and cement mortar. The compressive strength and flow characteristic of various mixes at various curing periods are studies. The study has shown that, the granulated blast furnace slag can be used as best alternative construction material over river sand. By these substitution and study one can achieve environmental protection as well as economy.

Use of cutting fluids in machining processes can reduce the cutting temperature and provides lubrication to tool and work piece. These translate to longer tool life and improved surface quality. Metalworking fluids are a major cause of health hazards for operators apart from being sources of environmental pollution thus necessitating research in dry and minimum quantity lubrication (MQL) machining. The introduction of coolant techniques such as near-dry machining so called minimum quantity lubrication (MQL) and cryogenic coolant have shown promising performances especially in terms of cutting tool life. Nowadays, MQL is widely used in machining performances.
Performance evaluation of nano graphite inclusions in cutting fluids with mql...eSAT Journals
Abstract Liberation of heat and generation of friction associated with any machining operation ever pose a problem which not only reduce the tool life but also impair quality of the product. Cutting fluids have been the conventional choice to curtail friction and temperatures in machining because of its lubrication and cooling actions. However, considering health hazards posed by the conventional cutting fluids to health of the workers and ecology, the quest is towards identifying alternative strategies to the usual flood application. Selection and use of proper lubricant that can improve the overall cutting phenomena which is an important aspect in reducing the cutting forces and temperatures The present work studies the use of nano cutting fluids in MQL which is a minimal cutting fluid technique, for turning operation using HSS and cemented carbide tools. Development of nano materials by nanotechnology technique, dispersing them in the cutting fluid improve the effectiveness of the cutting fluid and hence nano graphite powder is selected of particle size 80 nm in varying proportions i.e. 0.0%, 0.1%, 0.3% and 0.5% by weight are mixed in water soluble oil and applied drop by drop. Experimentation is carried out at different flow rates like 5 ml/min 10 ml/min and 15 ml/min with nanoparticle suspended fluids along with dry machining, flood coolant machining under constant cutting conditions. Experimental results are very encouraging with much reduction in surface roughness, tool flank wear, temperatures and cutting forces is observed in fluids with nanoparticle inclusions. Different properties of the nanofluids are estimated through a series of standard tests. Keywords: Machining, nano Graphite, minimum quantity lubrication, cutting fluids.

Enhancing Energy Efficiency of Thermochemical Vacuum-Processes and SystemsALD Vacuum Systems Inc.
The energy optimization of thermoprocessing equipment is of great ecological and economical importance. Thermoprocessing equipment consumes up to 40% of the energy used in industrial applications in Germany. Therefore it is necessary to increase the energy efficiency of thermoprocessing equipment in order to meet the EU’s targets to reduce greenhouse gas emissions. In order to exploit the potential for energy savings, it is essential to analyze and optimize processes and plants as well as operating methods of electrically heated vacuum plants used in large scale production.

a). EconomiserAn economiser is a mechanical device which is used a.pdfrajat630669
a). Economiser
An economiser is a mechanical device which is used as a heat exchanger by preheating a fluid to
reduce energy consumption. In a steam boiler, it is a heat ex-changer device that heats up fluids
or recovers residual heat from the combustion product i.e. flue gases in thermal power plant
before being released through the chimney. Flue gases are the combustion exhaust gases
produced at power plants consist of mostly nitrogen, carbon dioxide, water vapor, soot carbon
monoxide etc. Hence, the economiser in thermal power plants, is used to economise the process
of electrical power generation, as the name of the device is suggestive of. The recovered heat is
in turn used to preheat the boiler feed water, that will eventually be converted to super-heated
steam. Thus, saving on fuel consumption and economising the process to a large extent, as we
are essentially gathering the waste heat and applying it to, where it is required. Nowadays
however, in addition to that, the heat available in the exhaust flue gases can be economically
recovered using air pre-heater which are essential in all pulverized coal fired boiler.
b). Reheater
ins some heat either from the combustion gases leaving the boiler (if there is still much
temperature difference) or by adding more heat by burning small amount of fuel. The energy of
the exhaust steam with the gained heat increases the steam enthalpy of the steam and give a good
opportunity to generate much work with the low pressure turbine. The two works (High pressure
W_H and Low pressure W_L) are much greater than the heat added by fuel burned (Q1 and Q2),
so the efficiency increases. Another issue, the reheat helps in saving the turbine blades from
corrosion due to low dryness fraction x<0.88 which it may occur if one single stage turbine is
used.
c). Cogeneration
Cogeneration (Combined Heat and Power or CHP) is the simultaneous production of electricity
and heat, both of which are used. The central and most fundamental principle of cogeneration is
that, in order to maximise the many benefits that arise from it, systems should be based on the
heat demand of the application. This can be an individual building, an industrial factory or a
town/city served by district heat/cooling. Through the utilisation of the heat, the efficiency of a
cogeneration plant can reach 90% or more.
Cogeneration therefore offers energy savings ranging between 15-40% when compared against
the supply of electricity and heat from conventional power stations and boilers.
Cogeneration optimises the energy supply to all types of consumers, with the followingbenefits
for both users and society at large:
d). Turbocharging
A turbocharger, or turbo (colloquialism), from Greek \"\" (\"wake\"),[1] (also from Latin
\"turbo\" (\"spinning top\"),[2]) is aturbine-driven forced induction device that increases an
internal combustion engine\'s efficiency and power output by forcing extra air into the
combustion chamber.[3][4] This improvement over a.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
