DESIGN AND OPTIMIZATION OF A SUSTAINABLE CLOSED LOOP SUPPLY CHAIN NETWORK (SCLSCN) SCLSCN): A MULTI PRODUCT, MULTI ECHELON MULTI MODAL TRANSPORT AND MULTI PLANT TECHNOLOGY CONDITIONS
Get PDFA mixed integer mathematical model that concurrently optimizes the three intrinsic aspects of sustainability : cost, environmental effect, and social impact , was created for a general closed loop supply chain network. The suggested innovative hybrid model is developed to incorporates several real world aspects of SC execution, such as multi product, multi echelons, multiple production technology, and multiple means of transportation. On the GAMS/CPLEX solver, the weighted sum method is employed to solve that model after carrying out AHP to determine the weights assigned to objectives. In order to verify the accuracy of the suggested model, a case study was carried out in the context of an automotive SCND in Nigeria. The result demonstrates that model is capable of planning the SCLSCN
OPTIMAL PLACEMENT OF PHASOR MEASUREMENT UNIT (PMU) ON POWER NETWORK FOR REAL-TIME VOLTAGE MEASUREMENT
Get PDFDue to the advancement in electrical power systems, there is need for control, monitoring and protection so as to improve the efficiency, reliability and security of the power network. Phasor Measurement Units (PMU) as the ability to perform enlisted task also perform operations in real-time and dynamic monitoring scenario. The aim of this research work was to optimally site PMUs on IEEE 14- Bus and IEEE 33-Bus network using Graph Theoretic Procedure Method (GTPM) with the ability to maximally observe the whole power network. For IEEE 14-Bus network 5 PMUs were required while for IEEE 33-Bus network 14 PMUs were required for full observability of the networks. The GTPM was compared with previous method used on IEEE 14-Bus network. The PMUs measured voltage magnitude and phase angle was compared with load flow analysis using Newton Raphson method
MECHANICAL PROPERTIES OF DRAMIX HOOKED END STEEL FIBER REINFORCED CONCRETE
Get PDFConcrete and other cementitious materials are renowned for their poor tensile strength and brittle failure. One of the best ways to combat the brittleness of cementitious materials is by using steel fibres. This research aims to provide knowledge on the properties of steel fibre-reinforced concrete. The research will focus mainly on the mechanical properties of concrete reinforced with Dramix hooked-end steel fibre with different proportions of 0%, 0.5%, 1%, 1.5%, and 2%. The evaluation of concrete properties will include the workability of concrete using a slump test, compressive strength test, splitting tensile test, and flexural strength test at the age of 7 and 28 days of curing. The slump values of steel fibre reinforced concrete (SFRC) are lower to the tune of 1.74 – 6.97 %. There is an increase in compressive strength of SFRC from 4.37% - 15.11%. The maximum increase in splitting tensile strength of 15% was obtained at a steel fibre volume fraction of 2.0%. The addition of steel fibres significantly improves the mechanical properties of concrete. A 2% volume of steel fibre is recommended as the optimum steel fibre context in concrete for practical applications

Development and Fabrication of Onion Storage Unit
Get PDFDue to the inadequate capacity of onion storage in our country, we must build storage structures at the farmer’s level. This article is a small effort in that direction. Various types of onion storage structures discussed in this article are summarized from various sources and scientists. India is a region that depends on the agricultural sector. As per the report of the Financial Express in 2018, the contribution of the agriculture sector to GDP is 17–18%. Also, it provides employment to nearly 50% of the population. Despite all these facts, farmers are facing many problems on the fronts of infrastructure and technology. There are many prospects in the agronomy field for the implementation of technologies to store the last amount of onion in good condition. So, it requires a proper storage system. Various researchers are working in this area to develop designs and fabrications that are adoptable by farmers. Proper onion storage gives good results in the long term. This article reviews the proposed technologies and modifications made to them by various technocrats and researchers in the onion storage systems. This design of storage systems gives better results in the good condition of the onions, which gives better results in the quality of the onions
Structural and Thermal Analysis of Copper Coil Using ANSYS
Get PDFIn granular machine during extrusion process temperature of water increases this leads wastage of water. Using copper coil, it is possible to maintain the temperature of water. In this present work, structural and thermal analysis of copper coil using ANSYS has been carried out. Analysis is performed for ensuring the safety, stability, and longevity of structures to find temperature distribution, temperature gradient, and heat flowing in the model, as well as the heat exchanged between the model and its environment. Copper coil is modeled using SOLIDWORKS software. Thermal analysis has been executed to find temperature distribution, temperature gradient, and heat flowing in the model, as well as the heat exchanged between the model and its environment. Further structural analysis is carried out for determination of the effects of loads on physical structures and their components. After structural analysis, it is observed that, maximum principle stress induced in copper coil is 41.994MPa and minimum principle stress is -8.9271MPa. Through the thermal analysis, it is seen that, at inlet temperature of water passing through copper coil is 7oC at that point maximum stress is 7.0737MPa and minimum is 6.9945MPa. At outlet of coil, the temperature of water is 15oc at that point maximum stress is 15.005MPa and minimum stress is 14.937MPa
FEA and Experimental Analysis of Crane Hook Considering Different Cross sections and Materials
Get PDFCrane hook is significant component used for lifting the load with the help of chain or wire ropes. Crane hooks are highly liable components and are always subjected to bending stresses which leads to the failure of crane hook. Failure of a crane hook mainly depends on three major factors i.e., dimension, material, overload. To minimize the failure of crane hook, the stress occurred in it must be studied. Structural failure of the crane hook may happen as a crane hook is subjected to continuous loading and unloading. In this paper the design of the hook is done by analytical method for the different materials like aluminium, cast iron, high strength low alloy steel and Structural Steel. CATIA software is used for modelling the crane hook and ANSYS software used to find out the stresses induced in it. This result helps us for determining of stress in existing model. By predicting the stress concentration area, the hook working life increase and reduce the failure stress
