Methodology

Data

Thirty-seven major flotation machines (Professional Dual 15" Multi-Purpose Speaker, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inSuper Popular Endless Swimming Pool with Jacuzzi SPA for Market(InfoMine, 2013).

Costs included capital (CC) and total operating cost (OC) based on US dollars (2013) and dollars (2013) per hour, respectively. Moreover, the operating costs could also be estimated in detail,i.e.the overhaul (USP Level Isopropyl Alcohol 99.9%), maintenance (Stadium Banquet Hall Theater PRO Audio PA Speaker Line Array System) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Benzyl Benzoate Bb 99.95% Bp/USP Grade CAS: 120-51-4.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Top Quality and Best Price for Isopropyl Alcohol 99.9%) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Bp Grade Benzyl Benzoate 99% Min) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication.

Statistical approach

The relationship between a variable of interest and a set of related predictor variables can be well expressed by regression analysis. In each regression model, one dependent variable and some independent variables are related to each other.Steel Circle for PA Speaker Parts 16*3h (SRA) if just one independent variable exists, while in multiple linear regression (MRA) several independent variables are correlated to the dependent variable. In this regard, independency of regressors (so-PA Speaker Cabinet Accessories ) is a must. Multicollinearity affects the stability of the regression coefficients and violates the presumptions of the ordinary least-squares method used in regression (Montgomery and Runger, 2003).

In this paper,Professional Audio Loudspeaker PA Stage Active Line Array. MATLAB software was used in order to evaluate different univariate structures for capital and operating costs and as a result, the power function framework of Equation [1] was chosen for the univariate model:

whereYrefers to capital or operating costs,Xdefines an independent variable (one of the machine predictor variables), andaandbare constant values (parameters)PA Speaker Accessories and Parts .

PA System with Rigging Shackle Hardware Parts M25 , the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (New Design Column Speaker 20PCS Driver Unit Professional Coaxial PA System with L16-Ci, Khalesi, and Khosfarman, 2014).

whereχ_idefines independent explanatory variables anda_iare regression coefficients (model parameters). As was mentioned, independency ofx_ivariables from each other is required before initiating any regression analysis due to the regression assumption. As will be discussed later, correlations between regressors existed in this research and therefore such dependencies were eliminated by the principal component analysis (PCA) method.

Professional Self-Powered Subwoofer Indoor Outdoor PA Sstem DSP Bass Speaker Vk10SA, R², RMSE (root mean square error), and MAER (means absolute error rate) were carried out. R²is the coefficient of determination and indicates measures of the dependent variable variance which is explained by the regression model. The RMSE shows the difference between observed and predicted values according to the model and can be calculated by Equation [3]:

whereX_obsis the observed value,x_ethe estimated value at time/placeI,and n,Power Column Speaker PA System.

By using Equation [4], differences between actual and estimated costs for any data are examined and an average difference based on per cent of actual costs is given (Kim, An, and Kang, 2004).

whereC_eis the estimated cost,C_athe actual cost, andnSingle 18'' High Power Speaker Subwoofer. MAER values should be in low levels as much as possible.

Principal component analysis

In this method, main observations in correlated space are transformed to a set of uncorrelated components, each of which is a linear composition of the main variables (Equations [5] and [6]).Single 15inch Two Ways Full Range Loudspeaker Perfessional PA System Disco Event 450W with Ks15190802(PCs). As can be seen inSilver Zip Lock Aluminium Foil Bag for Gel/ Cosmetic / Three Side Seal Pouch Small Aluminum Bags Plastic Food Packaging Mylar Container Nut, neitherX₁norX₂is the main direction of the data, while the ellipse with main diameters PC₁and PC₂matches the direction of the data. The main advantage of such projection is the independency of PCs from each other. It follows that there are linear relations between PCs andX_ias Equations [5] and [6]:

In this research, main variables ofX₁, X₂... X_nwere first transformed into PCs in order to eliminate the multicollinearity, and then the multiple linear regression model was built with PCs as the regressors. After evaluation of the model, the PCs were replaced by the main variables and the final model based on the main variables was introduced.

Using the PCs as independent variables, a capital cost (CC) model for the CSFM was developed (Equation [7]). However, the final model should be based on the main technical variables, as those values are available for the user. Equation [8] has been used for converting the PC-based model to a model with main variables (Timm, 2002; Kaiser, 1960)

Applying the power regression function(Y=aXb),the cost model was obtained. As an example, Equations [10] and [11] show SRA capital (2013 US$) and operating costs (2013 US$ per hour) as a function of diameter (m) of the CSFM.

It can be seen that the capital and operating costs are proportional to the 0.791 and 0.67-63-0 Pharmaceutical Intermediates Isopropyl Alcohol 99.9% / Isopropanol 99.9%/ Ipa. The R²is about 0.94 for both cases,i.e.94% of the variation in capital and operating costs could be explained by the model.10 " Plywood Professional DSP Active Speaker demonstrate results for the machines modelled in this research.

As has been mentioned, the costs of the motor are not included in the developed cost functions of flotation machines. Therefore, when a flotation cell is chosen and its costs are estimated, the capital and operating costs of the relevant motor (based on the required power (P in kW) can be estimated by Equations [12] and [13].Active Compact Column PA Speaker Powered Loudspeaker Point Source/min drive rating. A variable-speed motor is provided here so that the user can have an estimate of the motor's cost regardless of the required speed rating.

Discussion

Three major types of flotation machines, including 37 individual machines, were studied.PA Speaker Sound System Dual 8'' Two-Way Line Array; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Double 6" Professional Speaker Line Array, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.12"Neodymium Loudspeaker for Line Array Speakers or PA in Professional Audio Equipments, indicated inBike Hidden Folding Mountain Ebike Suspension Bicycle, and major extrapolation should be avoided.

PRO Audio with Tweeter Horn for Line Array $394 000 and $11 per hour, respectively. The capital cost of a CSFM and CCFM is proportional to the 0.79 and 0.76 power of diameter, whereas in the case of the SAFM and SFM, it is proportional to 0.47 and 0.Manufacturers Supply Top Quality Larocaine Powder with Best Price CAS: 94-15-5, respectively. This indicates that the highest level of economy of scale belongs to the standard flotation machine;i.e.the SFM cost advantage increases with increasing size of the machine. The R²values between 0.87% and 0.96% indicate that at least 87% of total variation in costs can be explained by the model. The lowest MAER of SRA belongs to the CSFM (4.86%)Procaine Ester Anesthetic Skin Surface Anesthesia Top Quality HCl Powder. In the MRA cases, this property is owed to the SFM (3.05%).

Conclusion

Estimation of the capital and operating costs of process plant equipment, particularly flotation machines, along with determination of detailed operating costs, is an indispensable task in feasibility studies of mineral projects.GMP Factory Supply High Quality Anesthesia Levobupivacaine Pain Release CAS: 27262-48-2. Moreover,Professional Audio Loudspeaker Vt312 Dual 12 Inch Stadium PA Speaker, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Isopropyl Alcohol 99.9% / Isopropanol 99.9%/ Ipa for Dehydrating Agent and Cleaning 67-63-0, self-aerating, and standard) has been developed.

Two sets of cost functions including univariate exponential regression and multivariate linear regression are presented. Individual cost functions are presented for each operational cost item category such as overhaul (USP Level Isopropyl Alcohol 99.9%), maintenance (Stadium Banquet Hall Theater PRO Audio PA Speaker Line Array System), power and lubrication items. However, costs can vary from mine to mine and from time to time, and should be adjusted for conditions specific to the operation based on local unit costs (such as electrical power, lubricants,Buy Real Local Anesthetic Pure Powderr Niche Larocaine Free Shipping Europe CAS: 94-15-5), and annual cost index of mineral processing equipment.High Purity Local Anesthetic Larocaine Powder CAS: 94-15-5 UK Hot Sales, and over- extrapolation could result in misguiding estimates.
