This document discusses a mathematical model for minimizing trim loss in the one-dimensional cutting stock problem (1D-CSP). The model considers order lengths that need to be cut from stock lengths of raw materials. It defines the concepts of first-order and second-order sustainable trims, which represent thresholds for the maximum allowable trim at each cutting stage. Linear approximations are constructed to predict the total trim loss for any set of input data, based on computing trim losses corresponding to the sustainable trim thresholds. The model aims to provide a practical solution for industries like manufacturing transmission towers that deal with 1D-CSP.

A Comparative Analysis of Structure of Machine Tool Component using Fuzzy LogicIRJET Journal
This document presents a comparative analysis of using fuzzy logic versus conventional methods to design the structure of a machine tool component, specifically a lathe bed. It describes using both an I-section and box section for the bed design and calculating stresses using conventional trial and error methods. It then applies fuzzy logic by representing key design parameters like moment of inertia as fuzzy sets and calculating alpha cuts to determine optimal values that satisfy design requirements like limiting maximum stress. The results show that an I-section bed design optimized with fuzzy logic has lower stress values than a box section, demonstrating the advantages of the fuzzy logic approach over conventional trial and error methods.
Reliability Based Optimum Design of a Gear BoxIJERA Editor
The gear box represents an important mechanical sub system. In machine tools, the propose of a gear box is to provide a series of useful output speeds so that the machining operation can be carried out at its most optimum operating conditions high spindle speeds with low feed rate for roughing operations. An important aspect in the design of machine tool transmission is to keep the cost and volume of the gear box to a minimum. The probabilistic approach to design has been considered to be more rational compared to the conventional design approach based on the factor of safety. The existence of uncertainties in either engineering simulations or manufacturing processes calls for a reliability-based design optimization (RBDO) model for robust and cost-effective designs. In the present work a three shaft four speed gear box is designed using reliability principles. For the specified reliability of the system (Gear box), component reliability (Gear pair) is calculated by considering the system as a series system. Design is considered to be safe and adequate if the probability of failure of gear box is less than or equal to a specified quantity in each of the two failure modes. A FORTRAN program has been developed to calculate the mean values of face widths of gears for the minimum mass of gear box. By changing the probability of failure of system variations in the face widths are studied. The reliability based optimum design results are compared with those obtained by deterministic optimum design. The minimum mass of the gear box is increase as the specified values of the reliability is increased.

Nominal diameter, clamp length and thread pitch analysis for bolt preloadIAEME Publication
The document summarizes an analysis of various parameters that affect bolt preload, including nominal diameter, clamp length, thread pitch, and friction coefficients. It presents equations to calculate thread stress area, bearing area, and contributions of torque (T1, T2, T3) used to overcome friction and produce clamping force. The analysis shows that bearing friction requires the most torque (60-70%) and that variations in friction coefficients can cause a 40% difference in preload from the same applied torque.

Numerical modeling to evaluate pile head deflection under the lateral loadeSAT Journals
Abstract The complex behavior of pile head deflection under the lateral load can be studied using various analytical methods and the softwares. Often the lateral pile load testing is carried out in the field to confirm the calculated lateral pile capacity. However, even with the use of sophisticated latest softwares, the accurate deflection of pile head cannot be estimated. Hence an attempt has been made in this paper to evaluate the pile head deflection using the field load-deflection data and the corresponding soil and pile properties. A preliminary mathematical model has been developed using a technique of dimensional analysis (DA) to evaluate pile head deflection under different pile diameters, different pile materials and varying soil conditions. The estimated pile head deflection using DA equation is compared with 14nos. of measured lateral pile load test results conducted at the site. It can be observed from this study that, the dimensional analysis can be used effectively to estimate the pile head deflection. More variables based on more field results can be introduced in the mathematical model to increase the accuracy in the estimation of pile head deflection. Keywords: Pile head deflection, Lateral pile load, Dimensional analysis

In similarity to wood, they are assumed to be isotropic, resistance to weather, dimensionally consistent, hard, wear resistance and many other benefits and they are authenticated to best suited for wood processing methods and have huge economics benefits. First task was to find out why we use pine wood for supporting vibratory conveyor that too with combination of two wooden planks and one steel plank sandwiched between them. After studying a brief about pine wood properties it shows following advantages [1]. Key Words: Wooden Planks, Vibrating Conveyor, Composite Material, FFT and Spectrum Analysis.
Analysis of stress in circular hollow section by fea and analytical techniqueeSAT Journals
Abstract This study focus on stress calculation in a cantilever beam by FEA &Analytical techniques. To know the value of maximum load bearing capacity of any particular beam this study has been generated. Structural analysis is foremost requirement in a design process. Also when we perform FEA analysis of any structure we cannot blindly trust on its result. If we don’t have any past result data of that structure, it became difficult for us to know the deviation of result. For that purpose we may require analytical calculation result in order to compare result value of FEA. Hence in this study a range of load values are applied on cantilever beam by both techniques. Later graph has been plotted for different load values & verification of results is carried out. Keywords: Structure Analysis, CATIA, FEA and Benchmarking

First order shear deformation (FSDT) theory for laminated composite beams is used to study free vibration of
laminated composite beams, and finite element method (FEM) is employed to obtain numerical solution of the
governing differential equations. Free vibration analysis of laminated beams with rectangular cross – section for
various combinations of end conditions is studied. To verify the accuracy of the present method, the frequency
parameters are evaluated and compared with previous work available in the literature. The good agreement with
other available data demonstrates the capability and reliability of the finite element method and the adopted beam
model used.
Stepped or non-prismatic beams are widely used in many engineering applications
and the calculation of their natural frequency is one of the most important problem.
Several methods were used to calculate the natural frequency of stepped beam. In this
work, the Rayleigh methods (Classical and Modified) and finite element method using
ANSYS software were used for calculating the natural frequency of Hollow stepped
cantilever beam with circular and square cross section area. The comparison between
the results of natural frequency and frequency ratio due to the increasing the length of
the small part for these types of beams and for these three methods were made. The
agreement between ANSYS the classical Rayleigh results was better than the agreement
between ANSYS the Modified Rayleigh results for the two types of cross section area. The
maximum error of MRM was greater than that of CRM and the maximum error of circular
C.S.A. Was greater than that of square C.S.A. At the same dimensions. The natural
frequency of circular C.S.A was smaller than that of square C.S.A. for the same
dimensions

This document investigates stresses induced in curved beams using MATLAB and finite element analysis (FEA). It analyzes three cross-sectional shapes - trapezoidal, circular, and elliptical - for a crane hook subjected to a 100kN load. MATLAB code is used to calculate stresses in each section, finding the trapezoidal section experiences the lowest maximum stress of 171 MPa. FEA software ANSYS is also used to model each section and determine von Mises stresses, validating the results. The trapezoidal section is identified as optimal for withstanding the load with minimum induced stress.
This document summarizes and analyzes different feedback methods for adjusting manufacturing processes when setup errors result in constant or random offsets from the target value. It considers two cases: when the setup error is an unknown constant offset, and when it is a random variable with unknown mean and variance. The performance of Grubbs' harmonic rule, an integral controller, and a Kalman filter approach are evaluated based on their average integrated square deviation over a number of parts produced. The analysis shows how the choice of initial offset estimate and its uncertainty affect the performance of the adjustment methods.

Abstract Flexible cell formation is based on Group Technology. Group Technology rests on the exploitation of resemblances between products or processes, which makes the identification of products’ families and machines’ cells easier. We propose a new approach based on the language theory for product family grouping according to their manufacturing sequences. This approach uses linear sequences of the manufacturing products which are assimilated to the words of a language. We have chosen the Levenhstein distance for sequence classification. We are going to compare our method to Dice-Czekanowski and Jaccard’s methods and apply the vectorial correlation coefficient as a comparison tool between two hierarchical classifications. Keywords: manufacturing sequences, language theory, hierarchical classification, Group Technology.

Stepped or non-prismatic beams are widely used in many engineering applications
and the calculation of their natural frequency is one of the most important problem.
Several methods were used to calculate the natural frequency of stepped beam. In this
work, the Rayleigh methods (Classical and Modified) and finite element method using
ANSYS software were used for calculating the natural frequency of Hollow stepped
cantilever beam with circular and square cross section area. The comparison between
the results of natural frequency and frequency ratio due to the increasing the length of
the small part for these types of beams and for these three methods were made. The
agreement between ANSYS the classical Rayleigh results was better than the agreement
between ANSYS the Modified Rayleigh results for the two types of cross section area. The
maximum error of MRM was greater than that of CRM and the maximum error of circular
C.S.A. Was greater than that of square C.S.A. At the same dimensions. The natural
frequency of circular C.S.A was smaller than that of square C.S.A. for the same
dimensions

This document presents a new analytical method for identifying stability lobes in high-speed machining of thin ribs. It describes developing a stability lobe diagram that shows the relationship between axial depth of cut and spindle speed, with lobe number as a parameter. The method involves using experimental modal analysis to determine dynamic characteristics of the machine-tool system and then using mathematical equations to simulate the real and imaginary parts of the frequency response function. This allows predicting stable and unstable machining regions. The document outlines the specific steps of the proposed method and shows examples of simulating the frequency response function and stability lobes using Mathcad software. It concludes that the method can predict stability lobes considering workpiece flexibility and that future work will incorporate experimental validation.
IRJET - An Investigation of Stresses Induced in Curved Beams using MATLAB...IRJET Journal
This document investigates stresses induced in curved beams using MATLAB and finite element analysis (FEA). It analyzes three cross-sectional shapes - trapezoidal, circular, and elliptical - for a crane hook subjected to a 100kN load. MATLAB code is used to calculate stresses in each section, finding the trapezoidal section experiences the lowest maximum stress of 171 MPa. FEA software ANSYS is also used to model each section and determine von Mises stresses, validating the results. The trapezoidal section is identified as optimal for withstanding the load with minimum induced stress.
This document summarizes and analyzes different feedback methods for adjusting manufacturing processes when setup errors result in constant or random offsets from the target value. It considers two cases: when the setup error is an unknown constant offset, and when it is a random variable with unknown mean and variance. The performance of Grubbs' harmonic rule, an integral controller, and a Kalman filter approach are evaluated based on their average integrated square deviation over a number of parts produced. The analysis shows how the choice of initial offset estimate and its uncertainty affect the performance of the adjustment methods.
Sequences classification based on group technology for flexible manufacturing...eSAT Journals
Abstract Flexible cell formation is based on Group Technology. Group Technology rests on the exploitation of resemblances between products or processes, which makes the identification of products’ families and machines’ cells easier. We propose a new approach based on the language theory for product family grouping according to their manufacturing sequences. This approach uses linear sequences of the manufacturing products which are assimilated to the words of a language. We have chosen the Levenhstein distance for sequence classification. We are going to compare our method to Dice-Czekanowski and Jaccard’s methods and apply the vectorial correlation coefficient as a comparison tool between two hierarchical classifications. Keywords: manufacturing sequences, language theory, hierarchical classification, Group Technology.

Size effect of plain concrete beams–an experimental studyeSAT Journals
Abstract
The paper analyses the size dependency of the fracture energy (GF) and the effective length of fracture process zone (Cf) of concrete
determined as per the Bazant’s Size effect method and RILEM Work-of-fracture methods. The fracture parameters (GF,Cf) are
determined by measuring the maximum loads of geometrically similar notched plain concrete (M25) specimens of different sizes in a
size ratio of 1:5 with different pre-cast notch depths (a/d=0.15, 0.30 and 0.45) under three point bending through load-deflection
curves. In each notch depth ratio, 15 beams are cast and tested with 03 similar specimens in each size of the beams. Total beams
tested are 45.The variation of both the fracture energy and the effective length of fracture process zone as a function of the specimen
size and notch depth is determined using Bazant’s Size effect method and RILEM Work-of-fracture method. Fracture energy and
Fracture process zone length determined by Size effect method are found to be decreasing with the increasing notch depth ratios.
Fracture energy calculated using Work-of-fracture method is increasing with the increase in size of specimen and decreasing with the
increasing notch depth ratios.

This document summarizes research on optimizing the LZ77 data compression algorithm. The researchers present a method to improve LZ77 compression by using variable triplet sizes instead of fixed sizes. Specifically, when the offset is equal to the match length, they represent it with a "doublet" of just length and next symbol, saving bits compared to the standard triplet representation. They show this optimization achieves higher compression ratios than the conventional LZ77 algorithm in experiments. The decoding process is made slightly more complex to identify doublets versus triplets but still allows decompressing the encoded data back to the original.
Data compression refers to reducing the amount of space needed to store data or reducing the
amount of time needed to transmit data. Many data compression techniques allow encoding the
compressed form of data with different compression ratio. In particular, in the case of LZ77
technique, it reduces the data concurrency of an input file. In the output of this technique it conveys
more information that is actually not needed in practical. Removing the extra information from the
encoded file that makes this algorithm more optimal. Our task is to identify how much extra
information it conveys and how can we minimize it so that there is no trouble at the time of
decoding. Basically the encoded output of LZ77 is the sequence of triplets (a structure of encoded
output) that is in binary and having fix size. For making the triplets of fix size, sometimes we are
creating unnecessary information. We present the method of variable triplet size as a way to improve
LZ77 compression and demonstrate it through many experiments. In our optimization algorithm we
are getting more compression ratio compare to the conventional LZ77 data compression algorithm.

This document discusses a heuristic approach for solving a bicriteria flow shop scheduling problem with two machines where processing times and setup times are associated with probabilities and jobs can be blocked together. The problem aims to minimize total rental costs of the machines subject to minimizing makespan. A mathematical model is presented and notation is defined. An algorithm is then proposed that calculates expected processing and setup times, expected flow times, and equivalent job blocks before finding a near-optimal sequence to minimize the two objectives. A theorem is also presented showing that starting one machine's processing at a certain time does not alter the overall makespan.

Determination of stress intensity factor for a crack emanating from a hole inIAEME Publication
This document describes a study determining the stress intensity factor (SIF) for a crack emanating from a hole in a pressurized cylinder using the finite element method. A cylinder model with a hole and through crack is created in CATIA and imported into ANSYS for meshing and analysis. The SIF is evaluated using the displacement extrapolation method. The results show that the SIF value rises sharply when the crack tip is near the hole and stabilizes as the crack tip moves farther from the hole. The SIF values from finite element analysis agree well with theoretical equations, validating the proposed methodology.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

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.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
