1. Bandwidth management mechanism for wireless broadband networks

The high data rates offered by 3G Partnership Project (3GPP) and Worldwide Interoperability for Microwave Access (WiMAX) systems allow them to deliver a competitive advantage for mobile data network operators by boosting network performance to improve the user experience of new converged services such as streaming video, mobile Internet browsing and Voice over IP (VoIP). Converged services necessitate the support of different classes of traffic with widely varying bandwidth and QoS requirements, which need to be guaranteed by wireless networks. There are significant technical challenges in realizing these data rates. Several technology development directions are widely considered to be essential. At the physical layer, the transceivers will utilize both Orthogonal Frequency Division Multiple Access (OFDMA) and Multiple Input Multiple Output (MIMO) links, which provide the best known solution for robustness and spectral efficiency. However, user mobility, that may cause congestion, has a great impact on the performance and planning of the network because some cells might become congested in the long-run due to user mobility as a result of high congestion prices in neighboring cells. Therefore, it is important to create new standard for economic-based bandwidth and resource management in wireless networks to support ubiquitous and efficient access to broadband network information. In this project, we are going to build a bandwidth management system for real time traffic over wireless networks. The project is is expected to contribute significantly to the scientific community and telecommunication industry in developing future-generation information networks.
2. A cost-based algorithm for bandwidth provisioning in wireless broadband networks The rapid growth of telecommunications infrastructure in developing countries has been demonstrated by the increasing number of new international vendors and service providers who provide a variety of wireless services for home and mobile users. Leading edge wireless access technologies such as WiMax have been adopted in various areas while other emerging technologies such as 3GPP High-Speed Downlink Packet Access (HSDPA) and long-term evolution (LTE) have been under intensive focus as potential wireless standards for future BWNs. 3G services like triple-play, data, and video mobile services, have also been widely adopted by wireless service providers to address the versatility requirements of mobile users. Such heterogeneity in access technologies and wireless services has prompted the need for unified connectivity and comprehensive integration frameworks which will potentially reduce the resource management overhead and optimize the QoS for different wireless services. In this research, we are going to design a bandwidth provisioning algorithm that isolates the service classes by allocating Ki time-slots for each class i out of K total time-slots in a given time frame. In LTE and WiMax, time frames are divided into constant number of time slots with fixed time-slot duration measured in microseconds. The slot duration measured by number of bits transferred within the fixed time-slot duration may change on per-frame bases depending on the channel conditions and consequently the modulation and coding mode adapted at the current time-frame. The designed algorithm can help controlling congestion and exercise proportional fairness among connections in wireless network environment.

1. Low-Energy Nuclear Reactions (Open to PhD and Masters students)

One of the leading theoreticians in the field of LENR is presently within NAv6. His working experience with the other theoreticians and with many of the experimentalists provide a basis for the theoretical effort required to bring this energy source into acceptability among the academic skeptics and thereby open the gates of industry and government funding presently denied the field. Plans are underway to combine this capability with a working system in a local laboratory where a 'critical mass' of creativity and knowledge can produce a breakthrough in both the modeling and experimental results. Much of the financing for this effort will be provided by entrepreneurs seeking to 'corner' experts in the field and get an edge on the upcoming market. Malaysia would be an ideal location for manufacturing the commercial product of this effort.

As a sign that the time is right for this development, the experimental effort is spreading beyond the few university and government labs where individuals have been working on their own time and after their retirements for many years. Small amounts have been set aside by the US congress as a sign that some politicians recognize that the potential gain from this development is so monumental that even the major industries that would be hurt by a significant new source of energy must be considered of secondary importance. A recent patent application by a NASA Laboratory (Patent application number: 20110255645) will challenge the 2 decade policy of automatic rejection of patent applications in the field.

Sub-areas: Theoretical Modeling of interactions and processes

This work is an extension of a decade-long development to determine the means of overcoming the Coulomb barrier between two positively-charged nuclei. It also seeks to understand mechanisms that allow nuclear reactions without the normal consequences of energetic radiation. Transmutation of elements, a consequence of some of these reactions, could be as important in the production of rare-earth elements as it is in the production of heat energy.

Sub-areas: Extensions to Atomic and Nuclear Physics

In the process of exploring the implications of the observed low-energy nuclear reactions, several concepts in physics that have been previously ignored are found to be important. The ability of electrons to move to lower atomic orbitals without benefit of photon emission is one possible explanation of the means for low-energy hydrogen nuclei to get much closer together than previously thought. A deep atomic-electron orbital is predicted by the Dirac equation to be present in binary nuclei. This orbital has not been observed or recognized; therefore, it has not been accepted in the past. Evidence is now mounting for its existence and importance. A problem that has here-to-for been neglected is the nature of the Coulomb potential. This leads to new understanding of nuclear physics and relativity.

2. Nature of Light and its Applications (Open to PhD, Masters, and intern students)

Light is fundamental to the Universe. Evanescent waves are a portion of this light that has only recently seen major applications. This use of near-field light can also be applied to energy generation in thermo-photovoltaics. The present light laboratory is exploring interference effects aimed for fiber-optics communications; however, this work leads from the microscopic (monolithic-microwave integrated circuits, MMICs) to the macroscopic (e.g., directly solar-powered, space-based lasers).

Sub-areas: Interference effects: interactions and applications

Interference effects are important and useful in many applications. With on-chip optical communications, to overcome speed limitations of electrons in wires, becoming a goal, the effects of interference and evanescent waves must be understood as a source of losses and potential gains in high-speed integrated circuits.

Sub-areas: Fundamental concepts on the nature of photons

Photons, a part of the centuries-old argument about particles vs waves, have been explored in many ways. However, there are aspects that have not been examined on a physical level and resolved sufficiently to truly use them to our advantage. The very success of their mathematical description has impeded the search for a deeper understanding that could lead to new devices and concepts. We are seeking better models to define the nature of light and photons and exploring the potential of transmitting information faster than the speed of light.
3. Space-based Communications & Solar Power (Open to interns and Masters students only)

With new materials (already laboratory tested) and new concepts in terms of structures (dynamic rings and tensegrity), a fiber-optic-based communications network in LEO could be self-supporting within 5 years of project start. Within another 5 years, man could be lofting over 100 tons a day (and growing) into space with no rockets and no greater environmental impact than that imposed by the airfreight of a moderately large city today. In the following decade, with daily payloads exceeding 1000 tons per day, Space-Solar-Power stations could be beaming energy back to the earth in an easily and efficiently utilized form. Man will begin mining the moon, Mars, and the asteroid belt. Major industry will move closer to the energy source(s) and many polluting industries will no longer be economical viable on the earth.

Sub-areas: Circum-terra fiber-optic rings in LEO

Fiber-optic cables have remade communications on earth. However, they have limitations and costs associated with the gains. An optic fiber in low-earth orbit, LEO, would provide the high-bandwidth high-throughput capability without the delay-time penalty paid by using geostationary earth orbit, GEO. The concept has how developed to the point of exploring the ring-networks that it would provide.

Sub-areas: Space-based solar power for LEO and terrestrial use

Solar power is the primary energy source in near-earth orbit. It would be needed for the fiber communications ring. Once satisfying the needs in space, it could then be sufficiently developed to more economically feed into the terrestrial power grid. Several aspects of such a system and its components are being explored within NAv6. The best means of generating, storing, and accessing this energy for multiple applications is one topic of this effort.
