1. ADAPTION OF CLIMATE CHANGES SCENARIOS BY CREATING ALGAE_BRINE SYSTEM IN ARID AND COASTAL REGION
by Tamer Elgohary, Rasha Elkholy & Esraa Samy
Abstract

The climate change has become an important issue through the last years due to its accelerated effect that have been taken place all over the world. Global climate change has a serious sub sequences all over the world as a result of greenhouse gas emission and solar radiation activity especially in the coastal zone area, climate change includes many parameters such as rising temperature, rain and dust storms, floods and drought. These parameters have negative significant effect on urban and rural area along any coastal area that contributes continuous threats on population, shore line erosion, sea water intrusion, coastal water resources, economy, tourism, land use, pollution and the surrounding environment. The SLR is a major impact of the climate change scenarios due to the global warming and the melting of earth poles glaciers that will sink large part of the coastal cultivated land, the reduction of the cultivated land will cause the needs for finding alternative source of protein. In this paper we established an algae-brine system adjacent to the aquaponic system inside Heliopolis university campus, by the help of the brine that resulted from the RO unit inside the aquaponic system we were able to breed a spicy of algae that can tolerate high rate of salinity, The name of the algae  spicy is  Donaliella salina which is a rich source of protein and can be used a source of fish food inside the aquaponics system, At the end of this study a group of conclusions were deduced for its optimum breeding environment, Also EIA study was achieved to find out its effect on the surrounding environment.

2. STATISTICAL INFERENCE FOR TWO RAYLEIGH POPULATIONS BASED ON JOINT PROGRESSIVE TYPE-II CENSORING SCHEME
by O. E. Abo-Kasem r
Abstract

Analysis of jointly censoring data has received considerable attention in the last few years. In this paper, the estimation problem of life time for two populations follow Rayleigh distribution based on joint progressive type-II censored sample (JPC-II) scheme is developed. We obtained the maximum likelihood estimators (MLEs) of the unknown parameters when it exists. Bayes estimators of the unknown parameters using squared error (SE), linear-exponential (LINEX) and general entropy (GE) loss functions are considered. Further, we obtain both approximate and Bayes credible confidence intervals. The theoretical results of point and interval estimation obtained are assessment and compared through illustrative example and simulation studies.

3. NONLINEAR TRANSFORMATION AND APPLICATION OF TREASURY BOND PRICING BASED ON VASICEK MODEL
by Huang Yitao and Zhang Jingjing
Abstract

Vasicek model is one of the most classic models in the theory on term structure of interest rate. However, Vasicek model has a weakness, i.e. The drift function on linearity of instantaneous short rate does not correspond to actual features of interest rate. To overcome the weakness, based on Vasicek model, the paper linear conducts transformation, and verifies non-linear Vasicek model through the method of ordinary least squares(OLS). Then, Monte Carlo simulation is adopted to analyze the pricing of treasury bond, and compare pricing differences before and after transformation. According to results of analysis, transformed Vasicek model is more suitable for treasury bond pricing.

4. A METHOD FOR TRANSIENT HEAT CONDUCTION
by Jian Song, Lili Yan and Yingying Yin
Abstract

In this paper, we proposed a calculation method which combining radial basis function method and Houbolt method to solve the transient heat conduction problem. Houbolt method is used for discrete differences in time domain. In order to reduce the influence of shape parameter, this study proposed an improved radial basis function, and the improved radial basis function is used to compute the value of the problem. This method is accurate and stable, and it can solve the transient heat conduction problem excellently. Finally, three numerical examples are applied to illustrate the effectiveness of the proposed method.

8. THE SIMULATANOUS HAZARD REGRESSION BETWEEN THE FOURTH BIRTH AND FEMALE EMPLOYMENT IN EGYPT
by Mostafa Abd – El Hameed El Misery
Abstract

Woman employment is considered as an important factor for fertility behavior. The objective of this study is to explore the interactive relation between woman employment and their fertility transition. We specify a simultaneous hazard regression model of two processes: fourth birth events and employment events. In addition, we allow for unobserved heterogeneity that is correlated across the two processes. This allows us to analyze the interaction of the transitions explicitly; the potential endogeneity of each transition with respect to the other is controlled. We estimate this model using data of the 2012 round of Egypt Labor Market Panel Survey. The main conclusion from the study is that there is an endogeneity between woman work-entry and fertility behavior. Specifically, controlling for unobserved heterogeneity, transition to the fourth birth depresses the hazard of joining the labour market while a work entry event produces a significant decline in the hazard of the transition to the fourth birth. The study focuses on the need for policy to simultaneously address work opportunities and fertility to benefit from the reciprocal relationship between the two processes.
