• Artificial neural network based image encryption technique  
  by Shaimaa Fahdel 
  Abstract: Cryptography is one of the techniques of transformation of the information in safety manner. Encryption is best method to convert the data one form to another form. This converted data is in the form of cipher data which cannot be understand by a third person. The various types of encryption schemes are already available. In this review, we focus on the various encryptions, decryption techniques. This encryption and decryption scheme proposed using a chaotic neural network. The objective of this paper is that how to use artificial neural network with chaotic Cryptography. With the help of chaotic sequence we found the weights of neural network. A weights of artificial neural network are continuously updated on the basis of the generation of the key in the encryption algorithm. The MATLAB tool/software to implement the encryption algorithm were used.

• A DECISION SUPPORT STRATEGY FOR JATROPHA SEED COLLECTION FOR BIODIESEL MAKING THROUGH GRAPHICAL APPROACH  
  by S.P. Srinivasan, Deenadayalan G 
  Abstract: Abstract :Oil from Jatropha and Pongamia seeds are more appropriate in the production of bio-diesel. This bio energy replaces petro-diesel and deserves specific attention. However the warehousing and distribution of oil seeds is highly a dense task. This issue is being addressed by many supply chain models using different algorithms namely, Markov chain process, Integer Programming, Benders decomposition, etc., The above mentioned algorithms give variety of solutions in the respective systems. The proposed model recommends the method of finding the optimal distribution center(s) of Jatropha seed through optimized unilateral graphical approach with possible and necessary constraints. (Whichever applicable, and wherever needed).The supply chain process consists of four different levels of modules. This paper is focused on the initial level of process to identify the appropriate solution of distribution method using graphical approach algorithmically. The resultant solution obtained may go ahead to the next level of the module in the supply chain with network.

• A Study on the CAPM and its Extensions in Perceptive of Pakistani Asset Management Organizations  
  by Saleha Ashfaq 
  Abstract: This paper explains about the Capital Asset Pricing Model (CAPM), its capability and its implication in the real-world data. To crave this thirst, we form this study by using the earlier CAPM approaches (Lintner, 1965 and Sharpe, 1964) that are also employed by many latest researches. Though there is a lot of literature available on the extensions of the CAPM, still there is no consensus in the literature with respect to what a reasonable proportion of risk is, and therefore, regarding what is an appropriate measure for assessing risk-adjusted performance. Along these lines, the mission for robust asset pricing models proceeds. Owed to this, we chose 5 asset managing organizations for the Pakistani stock market KSE 100 Index for the time period of 2012 to 2015. We also employed descriptive test and robust test ratio on our selected data. The finding of the research shows a significant result and suggested the good performance of assets management organizations.
