Abstract:The multicarrier-code division multiple access (MC-CDMA),which is the combination of direct sequence CDMA (DS-CDMA) and orthogonal frequency division multiplexing (OFDM) techniques, offers various advantages over single-carrier CDMA system. Some of the advantages are that MC-CDMA systems possess can remove the intersymbol interference (ISI) and enhance narrow-band interference suppression capabilities. So the MC-CDMA technique becomes a focus in the field of mobile communication. The authors introduce the typical MC-CDMA system model, discuss the decision statisticalvariable in Rayleigh fading channel included the CW interference, and give the expressions of probability of error in uplink. An approach is proposed with Modified Equal Gain Combining (MEGC) to decrease the effect of CW interference. Theoretical analysis and numerical results show that the anti-CW interference performance of MC-CDMA system can be improved used the MEGC approach.

Abstract:The heterogeneous nature of metallic materials result in residual microstress fields during plastic deformation.The energy stored in the residual microstress fields affects the subsequent plastic deformation. Based on this concept, a nonclassical constitutive model is developed. On the other hand, it is found that there exists difference of dissipative plastic energy between different plastic strain paths. A dissipative plastic energy based hardening parameter is proposed and introduced into the hardening function, which isthen embedded in the non-classical constitutive model. The stress responses of 304 stainless steel subjected to biaxial non-proportional loading are analyzed and the results coincide well with the experimental results.

Abstract:By analyzing the characteristics of magnesium volatilization and linear growth kinetic of Al/ Al_2O_(3 )in directed oxidation of Al-Mg alloy, as the formation process of MgO is considered to be the process of which Al_2O_(3)dissolved in the scale MgO and MgO is partially n-type oxide, formation condition of Al_2O_(3)is established easily in the coure of oxidation. Volatilization of magnesium is to promote the growth of p-type MgO in the surface layer and the formation of Al_2O_(3 )in the inner layer of n-type MgO, and to promote the transformation of MgO toMgAl_2O_(4).MgAl_2O_(4)plays an important role in the formation process of Al_2O_(3), growth stress between MgO and MgAl_2O_(4)cause the formation of cavity in the MgAl_2O_(4 )and aluminum alloy melts is easier to transfer to oxidation front by means of this cavity. The transformation velocity ofMgO to MgAl_2O_(4 )depends on growth kinetic of Al_2O_(3),the faster transformation velocity of MgO to MgAl_2O_(4)is main reason that growth kinetic of Al/Al_2O_(3)transformation exhibits linear relationship.

Abstract:A new kind of evaporative heat transfer experiment for the cooling process of condensers is conducted. The test coil is immersed in an air-water bubbling layer. The air-water two-phase flow passes through the heating tubes of the coil. Due to the motion of the air bubbles in the water, a thin water film forms on the surface of the heating tubes. As the air bubbles passing by the tubes the water is evaporated into the air. The tubes of coil reject heat to the water film, and the evaporation of the water film then rejects heat to the air bubble stream. This heat transfer mode significantly increases the heat transfer coefficient between tubes and air. The consumption of the power of a water pump can be decreased. Moreover, the airflow rate required is less than that of an air-cooled condenser.The pressure drop of air through air-water bubbling layer and the heat transfer between the tubes and water are experimentally investigated in the paper. The results show that the factors affecting the pressure drop and the heat transfer coefficient involve the pore geometry of sieve plate, the height of the air-water bubbling layer, the air flow rate through the sieve plate and the heat flux of tubes. The heat transfer coefficient between tube and water is two times larger than that of falling film of water on the outer surface of tube.

Abstract:Since China adopted formalized and standardizedprocedures of tender and bidding in the construction industry, many illegal actions have been prevented effectively. However, the together-conspired bidding, a new illegal activity,recently emerged in many regions of China. It is widely believed that the establishedfair competition system will be frustrated and the healthy development of the industry will be harmed, if the together-conspired bidding can not be controlled. This paper firstly introduces the background of the together-conspired bidding and stressed the necessity of preventing together-conspired bidding. Then, the whole procedure of together-conspired bidding is studied and ananticipated profit model fortogether-conspired bidding is provided from the economic angle. According to the analysis on interactions between the economic factors and the anticipated profits, some strategic methods to prevent the together-conspired biddingare recommended.

Abstract:When studying on the supervision on listed company performance manipulation, the administrator's role has been emphasized increasingly. By setting up a game model, the article analyzes the performance manipulation made by the listed company's administrator. The analysis shows that the optimal performance manipulation strategy taken by the administrator is determined by the profits obtained by China Securities Regulatory Commission (CSRC) and the prior probability of the listed company performance categories made by CSRC, while the optimal supervision strategy taken by CSRC is determined by the final profits of the listed company. Thus, it is obvious that there is a mutual guessing and influencing relationship between the listed company's administrator and CSRC. Finally, the game model constructed is further analyzed by employing it in the real cases.
