To effectively harvest vibration energy from pavement without affecting driving comfort and safety, parameter optimization was done with the orthogonal experiment design and the finite element analysis. L16(44) Taguchi’s orthogonal experiments were carried out with planted depth, PZT material, PZT diameter and thickness as optimization parameters and with open voltage and pavement displacement ...

We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both entry of new firms and productivity improvements by continuing firms. The model generates a non-degenerate...

This study aimed to apply the Taguchi optimization technique to determine the process conditions for producing synthetic lightweight aggregate (LWA) by incorporating tile grinding sludge powder with reservoir sediments. An orthogonal array L16(4⁵) was adopted, which consisted of five controllable four-level factors (i.e., sludge content, preheat temperature, preheat time, sintering temperature,...

We study a model of firm price setting with customer markets and empirically evaluate its predictions. Our framework captures the dynamics of customers in response to a change in the price set by firms, describes the behavior of optimal prices in the presence of customer retention concerns, and delivers a general equilibrium model of price and customer dynamics. We exploit micro data on purchas...

Catalytic ozonation has been recognized in the scientific community as an efficient technique, reaching elevated rates of recalcitrant organic material mineralization, even at the presence of scavenger species of hydroxyl free radicals. This study presents the most significant factors involving the leachate treatment stabilized by the municipal landfill of the city of Guaratinguetá, State of Sã...

In this research paper, E 250 B0 as per IS: 2062 steel material are turned on computer numeric controlled (CNC) turning center by using Chemical Vapor Deposition (CVD) coated cemented carbide inserts of 0.8 mm and 1.2 mm. This paper discusses an investigation of effect of process parameters (speed, feed, depth of cut & nose radius) on responding quality parameter (boring operation). This study ...

Evolution of the Industrial Wage Structure in China Since 1980 Industry mean wages in China have exhibited sharply increased dispersion since the early 1990s. The upward trend in differences of average wages among major industry groups parallels increases in wage and income inequality not only between rural and urban sectors but within the urban economy as well. Research on the trend has focuse...

Due to the high mechanical strength of metals used in implant manufacture, which makes them difficult work with using other machining techniques, electrical discharge (EDM) is frequently employed production implants. In this study, effect powder ratio and EDM parameters CoCrMo alloy, widely, powder-mixed on surface roughness machined part was investigated through response methodology. AISI 316L...
