The Modeling of Total Cost and Revenue in Stock Market on Economics
Page no 307-309
The relationship between investment and shares is established to find the intrinsic nature. It is found when the best labour is 6 the cost is low and the number of shares are 1000 with the intersection of 1~4 RMB which is net profit point. When the best capital is 6 units the profit will be 5 RMB and the profit point is 1400 of the number of shares with the 5 RMB. The profit may become the positive at 780 pieces when the best labor is one. It explains that beyond this point the total net profit may be 3~4 Yuan may be best net profit in average profit. TR£2TC that says the Tpro may be best start because TCquan£0 in intersection between Tpro and TC. The total profit will be 3~4 Yuan according to the best labor and capital. The best labor is 1 whilst the best capital is 6 in this condition. In total TR³2TC is the valid value to make more profit which is concluded in this paper.

Specific nanoparticles are designed in order to deliver the different materials. Controlling the size, shape of nanomaterials during nanoparticles synthesis leads to effective synthesis of nanoparticles that can be combatable to electrical system. Iron based nanoparticles are most efficient due to low cost and high adsorbent efficiency as compared to the other nanoparticles through the action of magnetic field with ionic exchange capacity for heavy metals removal. Nanofilters are used for filtering the chemical pollutants found in wastewater. Acid treatment leads to precise synthesis of nanoparticles through the formation of biopolymers that can be disintegrated into smaller components or individual’s molecules. Gold nanoparticles are also much reliable as compared to the other nanoparticles as they are more influenced by the intensity of light. Scanning tunneling microscopy has become technique to provide the electric data about the specific atom or particles by following the princes of scanning under chemical investigation. X-ray spectroscopy is used for the analysis of that analysis usually heavier than oxygen. Electron energy loss spectroscopy (EELS) that detect the particular nanoparticles by loos of energy by passing through the samples or specimen.

Optimization of Cutting Parameters of Tool Wear in Turning Operations: A Review
A. Adamu, M. A. Bawa, A. M. Abioye
Page no 315-319
Tool wear is one of the major factors that contribute to surface quality, productivity and accuracy in machining. It also determines production flow by increasing the number of shutdowns for tools reshaping. Tool wear is related to cutting process parameters (depth of cut, spindle speed and feed rate), the surface nature of the metal (scaly or smooth), the cutting forces and thermal condition at cutting zone. This paper present review of various works on optimizing the tool wear rate during turning operation. Also, it presents techniques used in monitoring the processes and methods of determining the rate of tool wear with their results in an orthogonal machining operation on different type of materials.

Maximum Likelihood Channel Estimation for Space Time Block Code - Orthogonal Frequency Division Multiplexing
Nguyen Le Thai, Nguyen Vu Anh Duy
Page no 320-325
Multiple Input Multiple Output -Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a promising technique for broad - band communication over mobile wireless channels. This paper presents channel estimation methods for Space Time Block Code - Orthogonal Frequency Division Multiplexing (STBC-OFDM) system. Expectation – Maximization based on an iterative algorithm and Decoupled Maximum Likelihood method are used to reduce computational complexity without loss of estimation accuracy. Simulation results show that the effectiveness of the Decoupled Maximum Likelihood method is improved.
