research field:

Multi-Agent System, Agent technology, Web service, Agent Communication Language.

my review:

I came to this field since 2002 with the vision of an agent-prospered web which was convinced by my subsequence researches. Long ago, I believed that computerized intelligence and the evolving network environment had been mature enough to start populating the electronic world with humanized entities. During 2003, I led a small team through the development of Web Agent Framework. The system is built on top of .Net Framework and web service. This framework of MAS is different from the others because it brings agent concept from the technology (hidden) layer to authorized entity (user interface) layer. It finds out a way where general purpose agents could be immediately helpful to Internet/Intranet users and to establish a visible virtual human-relationships on the network. One important conclusion from this project is that, in the future, intelligent enterprise will embrace agent technology and the popularity of agent system should be first guaranteed on the network before more versatile agent enterprises could exist.

research field:

Ubiquitous computing

my review:

This field is a vision and lots of applications. When I was writing specifications for Web Agent Framework, I had already came into this realm without knowing its name. Later, when I discussed it with other people, I often argued that the driving force of ubiquitous computing lies not entirely in designing many network situated electronic devices, but more in designing an universal agent society where lots of Internet/Intranet users could immediately be addicted to its services. In other words, I think software application might be a faster way to instill this concept than hardware application. But in the long run, ubiquitous computing definitely will bring more versatile networked hardware in to our daily life.

research field:

Neural Network, Compiler technology, Parallel distributed system

my review:

Neuron Network is the earliest field of study that I am involved, but it is also the least implemented one (i.e. I have not had any major projects on it for a long time). I adjourned my investigation into Neuron Network, because I had not then found any particular point that I could get in. I had seen the same pattern/method be applied in many different places, such as pattern recognition, data mining, machine learning, bioinformatics, etc. During that time, I thought that neuron network application was as perfect as it is simple. Yet, much of my early passion was about the fascinating world in the system level of the human mind and the delicate models of bio neurons, all of which seemed to be totally neglected in the digital world.
In 2004, I formed the prototype of Neural Parallel language which I later concluded that it was likely to become the next generation high-level programming language. It was designed under the premise that all front end software in the future run in a distributed environment and (co)operate in a manner similar to neural networks. In the new language prototype, physical network logic (topology and certification) is not programmed with codes, but compiled with a visual compiler and handled through runtime environment. Late in the same year, I made an important break through on brain simulation, which resulted in a theory for the human brain. To demostrate it, I have applied it to learning and synthesizing 3D human animations in my game engine.

research field:

Human Computer Interface

my review:

Due to web technologies, many software systems, from backbones to front ends, are migrating from standalone applications to cooperative ones. This transform leads to a fully dynamic and distributed environment in the software world. It impacts not only the way software works, but also how it looks, or its user interface with human operators. User interface means both application interface and programming interface.

research field:

Computer graphics, Networking, Security, Virtual reality, 3D modeling and physics simulation, Scripting and programming language, Computer Game engine

my review:

These research fields, of which I did not come into much depth, are mirrors of present day technologies. I knew them through the development of one of my project: ParaEngine. ParaEngine or Parallel Distributed 3D Game Engine aims to develop networked, cooperative, high-quality 3D games. Local game worlds developed with the engine can easily merge into one community and together compose a large and evolving virtual gaming world on the Internet or Intranet. NPL is the enabling technology to script the ever evolving game world logic on the network.

research field:

Reconfigurable computing, cross-platform programming, computer architecture, micro-instruction design, SOC, HDL and operating system for embedded devices

my review:

I have applied knowledge in these fields of study through taking over tasks from national projects in research Institutes. I was the sole developer of MicroWindows program development and embedded-device simulation platform: It is part of Wearable DVD project at HIT. I was also system designer and developer in: Microprocessor and peripherals for motion control system -- A verilog implementation optimized for FPGA with reduced MIPS instruction set and specialized I/O controls. It is part of the One-chip motion control system in corporation with the International Rectifier Corp. and high density servo control system at Harbin Institute of Technology.
