92 Words1 Page

Relation is a subset of Cartesian product of domain [4]. Relation Algebra is a procedural query language that consists of a set of operation on the Relation(s). Example of operation in Relational Algebra are SELECT, PROJECT, UNION, and DIFFERENCE (See Fig. 2). Example; when src_ip = 30.0.0.0/30, dst_ip = 40.0.0.1, dst_port = 80, and action = deny, it can be mapped to Relation 1 (R1) as shown in Fig. 2, while R2 is the relation that is mapped from rule; src_ip = 30.0.0.0/31, dst_ip = 40.0.0.1, dst_port = 80-81, action = accept.

    After the normalization module the request is passed on to the Protocol Validation and Analyzer module where it is matched against the semantic rules that are generated by ontological models in the knowledge base for identifying malicious content in input validation. Protocol Validation module caters to the violation of protocol specification whereas the Analyzer handles all other web application attacks. If the input content matches any of the rules the request is blocked and a log is made for the said attack. Also in protocol validation attacks, an attacker tries to send an abnormal request that does not follow the RFC 2616 (Hypertext, 2014) standards.

The pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death.

    I used the guide to do the initial setup for each phone. I was able to achieve full connectivity using Free PBX and asterisk 13. For asterisk 13 there is an option to use PJSIP extensions over CHANSIP extensions. I chose to use PJSIP over CHANSIP is because PJ has a smaller connection and is overall more reliable than CHAN in asterisk 13. I learned that from trial and error with some troubleshooting in-between.

However i was able to use a visual aid with Hannah that showed her how to wash her hand properly. The steps had both text and a visual with a simple 4 step instruction. Hannah was encouraged to ask questions before and try to follow as best she could on her own.
