In Industrial systems, Supervisory control and data acquisition (SCADA) system, the pseudo-transport layer of the distributed network protocol (DNP3) performs the functions of the transport layer and network layer of the open systems interconnection (OSI) model. This study used a simulation design of water pumping system, in-which the network nodes are directly and wirelessly connected with sensors, and are monitored by the main controller, as part of the wireless SCADA system. This study also intends to focus on the security issues inherent in the pseudo-transport layer of the DNP3 protocol. During disassembly and reassembling processes, the pseudo-transport layer keeps track of the bytes sequence. However, no mechanism is available that can verify the message or maintain the integrity of the bytes in the bytes received/transmitted from/to the data link layer or in the send/respond from the main controller/sensors. To properly and sequentially keep track of the bytes, a mechanism is required that can perform verification while bytes are received/transmitted from/to the lower layer of the DNP3 protocol or the send/respond to/from field sensors. For security and byte verification purposes, a mechanism needs to be proposed for the pseudo-transport layer, by employing cryptography algorithm. A dynamic choice security buffer (SB) is designed and employed during the security development. To achieve the desired goals of the proposed study, a pseudo-transport layer stack model is designed using the DNP3 protocol open library and the security is deployed and tested, without changing the original design.

Cognitive theory of Multimedia learning has been a widely used principle in education. However, with current technological advancements and usage, the teaching and learning trend of children have also changed with more dependability towards technology. This research work explores and implement the use of 3D Animation as a tool for multimedia learning based on cognitive theory. This news dimension in cognitive learning will foster the latest multimedia tools and application driven through 3D Animation, Virtual Reality and Augmented Reality. The three principles, that facilitate cognitive theory of multimedia learning using animation, addressed in this research are temporal contiguity principle (screening matching narration with animation simultaneously rather than successively), personalization principle (screening text or dialogue in casual form rather than formal style) and finally the multimedia principle (screen animation and audio narration together instead of just narration). The result of this new model would yield a new technique of educating the young children through 3D animation and virtual reality. The adaptation of cognitive theory through 3D animation as a source of multimedia learning with various key principles produces a reliable paradigm for educational enhancement.

In this paper a unique way of rigging a bipedal character is discussed inside 3Ds Max, using constraints, wire parameter setup and linking the controls. 3Ds Max is more commonly used for game character modeling and rigging. For this purpose a built-in Biped setup is present that is a pre-rigged structure, which can be easily applied on any bipedal character type easily and efficiently. However, the built-in Biped system lacks the functionality of manual control and motion retargeted manipulation, mostly found in custom rigs. This proposed system builds a custom rig using a unique approach of combining multiple tools and expressions.
