The hydrostatic transmission is one of the most important applications in the fluid power systems. It gives smooth change in output speed, torque and power as per the design requirements. Present article deals with various losses of the hydraulic pump and motor using a closed circuit hydraulic drive. The drive basically consists of a variable displacement axial piston pump that supplies pressurized fluid to a variable displacement bent axis hydro-motor. In investigating the pump/motor performance, bond graph simulation technique is used to model the drive system. Various losses of the pump and motor are accounted in the model by suitable resistive elements. The characteristics of them are identified through experiments. The predicted performance of the pump/motor is studied with respect to the displacement and load at the same time they are validated experimentally. The investigation made in the article identifies the control strategy which will be useful for the practicing engineers to select best combination of the pump and motor displacement for optimizing the drive performance and minimizing the losses as well. The study performed in this research work will be useful for the similar hydraulic configuration used in mobile equipment.

In underground mines, the problem of efficiently scheduling and allocating weekly operations has a major impact on the long-term productivity of the mine. The problem of selecting the optimal locations for operations in an underground gold mine is a complex task. It is not solved by simply selecting the levels with the richest grade because the transportation network for ore in an underground mine has a diverse set of capacity constraints that can frustrate immediate mining of all the richest levels. To solve this scheduling difficulty, we formulated a new mixed-integer network flow model of the problem of weekly allocating mining operations in an underground goldmine such that the total gold mined (in ounces) was maximized subject transportation capacity constraints. The model was applied an underground gold mine in Red Lake, Ontario, Canada. The results were compared to those of a two greedy heuristic models that were designed to represent the decision-making heuristics that are currently used at the mine. It was found that the new model yielded solutions that improved upon the two greedy heuristics by 14.7% and 6.0%, respectively. The results of this research illustrate that the development of this optimization model can support decisions to improve a gold mine’s productivity.

Price uncertainties are increasing as diverse buyers and sellers are coming into the fuel and minerals market. There are supplyside uncertainties due to resource depletion, supply chain problems, and prolonged wars and conflicts. Uncertainties enhance risk. Moreover, standard trading practices in the minerals and oil and gas industries like long-term supply agreements with rigid price–fixing mechanisms are being challenged by short-term trading agreements and contracts where the price rigidities are non-existent; the market determines the price on the basis of the supply of buyers and sellers in an open market. Moreover, the market for derivatives of minerals and oil and gas is becoming more pronounced as the various uncertainties to secure materials supply are growing. In order to tread in the unknown waters of flexible trading, the mining companies can think of opening a profit center with qualified people to tide over the challenges and to gather knowledge of the trading system, which will also influence how the financing of the project investments would take place in the future.

One of the most popular indirect methods for investigating the subsurface information is through borehole record. The information obtained from a bore log will provide the subsurface scenario with regard to the soil and rock mass profile, stiffness of the material, weathering grade and quality of the rock material. It is wise to obtain as much as possible useful information from it for any civil engineering design including its excavatability assessment. On the other hand, seismic velocity is also commonly used to describe subsurface information as it furnish actual profile of the subsurface along the survey line. Seismic survey is assumed to be relevant geophysical method to characterize the boundary of soil-rock. Although the field borehole information and seismic method has been widely applied in the ground investigation, their applicability in assessing excavation performance is still debatable, especially when it involves thick soil-rock interaction zone in tropical region. The objective of this study is to investigate the applicability of ground profile obtained from the field borehole information and the seismic survey in surface excavation works. Field studies were carried out ontwo on-going excavation sites namely Nilai and Kota Tinggi involving non-bedded -bedded rock masses, namely granite. This study aims to present the relationship between seismic refraction method and boreholes were to investigate their effectiveness in assessing the ground information for excavation purpose. A sets of boreholeswere drilled approximately on the same path of seismic linesto obtain relationship between those methods. The seismic survey results are evaluated with Standard Penetration Test (SPT), strength index, core recovery (CR) and Rock Quality Designation (RQD) information. Upon obtaining that information, trial excavation were carried out using different size of excavator machines to determine its productivity rate. This study provides useful information on the excavatability of ground materials by using various type of excavating machines, based on the most commonly used of ground investigation tools, which are boreholes and seismic velocity method.

For stable oven operation and prolongation of the coke oven life, it is important to remove excess carbon formation on the coke oven wall. It is considered that the carbon formation rate is influenced by the gas components generated during carbonation, the gas velocity and oven wall temperature are not uniformly maintained, as a result of smoke pushing. The smoke pushing is not favourable for the good health of the coke oven battery. In this paper, the smoke pushing can be rectified by proper maintenance of the gas path. Energy consumption and economic growth are interwoven, and rising energy levels always represent rising energy consumption. Coke is a reducing agent and a load-handling tool in blast furnaces. By this rectification, the coke oven gas flow was reduced from 17600Nm3/hrs to 17300Nm3/hrs without any extra manpower cost. The experimental set-up implementation of this modern proposal in a coke plant will make coke more extra energy efficient with no other extra costs.

The vertical throughflow effect is investigated on the onset of porous convection by considering a cubic density-temperature relationship and using the Forchheimer-Darcy model. The stability eigenvalue problem is explained numerically using the Galerkin technique. Contrary to the linear density-temperature relationship, the direction of throughflow alters the onset of convection. The throughflow dependent Péclet number is found to stabilize the fluid motion against convection and the upflow is found to be either stabilizing or destabilizing than the downflow depending on the values of thermal condition parameters λ1 and λ2. A destabilizing effect on the onset is observed with increasing λ1 and λ2. The Darcy number Da and the Forchheimer drag co-efficient, cb instability characteristics have been investigated and depicted graphically.

Enormous usage of cutting fluid in industries is reporting the issues related to health of employee, environmental pollution which promotes the Minimum Quantity Lubrication (MQL). The study reports surface roughness modelling in CNC turning under minimum quantity lubrication of EN 24, taking into account effect of cutting environment, cutting conditions using artificial neural networks (ANN). The optimisation of models are processed using the input-output data sets, ANN model, the repetitions in training the neural network, rate, hidden nodes and the training function. ANN analysis with multilayer feed forward structure under MATLAB is adopted in the analysis. Finally, After the training, the ANN is tested in order to evaluate its predictive and generalization performances. Testing the ANN is carried out by applying a new input data set, which was not included in the training process. The well known statistical tools coefficient of determination is used for this benchmarking. The adequacy of the ANN is evaluated by considering the coefficient of correlation (R).

The global competitions are making rapid changes in production. Procedure integration and seamless flow of information and data play a vital role in productivity. The planning order improbability, manufacturing lead time and lack of systematic approach are the main concerns in production industries. Enterprise Resource Planning (ERP) and Lean Manufacturing (LM) are the two distinct processes to deal with the above mentioned concerns for competitive manufacturing. ERP focuses on data and schedule accuracy and ensures repeatable and predictable processes. LM concentrates on identifying and eradicating or minimizing all kinds of manufacturing wastes and focuses on reducing process inconsistency. The paper narrates about some holistic approaches that can be practiced with SAP ERP tool in order to achieve the efficient materials planning, master production schedule and capacity planning.
