The University of the Philippines Los Ba ̃nos cur- rently offers a number of applications to its students and staffs. However, a limited number of servers and hundreds of users accessing different services at the same time would results to heavy traffic and a huge response time. A private cloud was setup to enable easy and flexible deployment of virtual servers within the network using Eucalyptus Private Cloud. A load balancer was deployed in the cloud to properly distribute task among the virtual servers, provide faster response time and prevent the possibility of data lost due to server failure. The load balancer was developed using Java and is composed of four classes: MyServlet, Balancer, Server and Request. The load balancing scheme used took into consideration not only the load and capacity of the servers but also the resources needed by each incoming request. A graphical web interface was also provided for the network administrator to visualize and monitor the current status of each virtual machine in the cloud.

The researchers developed a system which resides on a machine different from the one keeping the Squid access logs. Both machines belong to the same network. This was done to allow larger memory allocation for the system. The researchers created a log parser to get the logs from the machine containing the Squid access logs through SSH every two hours. The parsed data is stored in a database managed by squiGIS. The data stored in the database was used to analyze the logs and create a web- based monitoring module for the system. Search functionalities specified by the UPLB Information Technology Center were also incorporated into the system.

EMedyx is an automated medical records system, for much easier storage, retrieval and manipulation of information. It reduces medical errors and causes health services to be much cheaper and faster. And makes access to important clinical data around the globe possible. Access to the system is provided through web-based application, which is developed mainly using PHP and Java(for login), and stand-alone desktop applications, which are created using C#. Both software interacts with each other via SOAP webservice. But what makes it more interesting is its improved security through the use of smart cards to enhance protection similar to credit cards. This study will focus on eMedyx’s security module. Mutual Authentication, Encrypted code submission, SSL certification, and MD5 encryption will all be applied into both web and standalone applications of the system, along with all other identification and user level authorization functions.

Cancer is one destructive phenomenon in natural sciences. The process in which cancer cells invade or grow within a matrix of cells is very complex. To fully understand and to model it is indeed a great challenge in modern science. In this study, we adopted the model used by Mehrdad Ghaemi and Amene Shahrokhi. This model is the Cellu- lar Potts Model combined with the Lattice-Gas Cellular Automata which simulate the growth of cancer cells. The model exhibits cell-to-cell interactions where a cancer cell has a tendency to be necrotic, be quiescent, to proliferate (mitosis), or undergo apoptosis depending on probability formulas which are also dependent with energy formulas. The simulation of this model was implemented through CUDA which uses the Graphical Processing Unit (GPU) instead of the Central Processing Unit (CPU). GPU is a useful tool in implementing simulations of problems involving intensive computing and high parallel computations.
