Title: Challenges of Resource Allocation in Network Virtualization
Abstract: Network virtualization technology creates multiple tenants on the same physical infrastructure in a cost-effective and dynamic manner. It plays a key role in the cloud computing, which provides resources and services to users through the Internet. An infrastructure as a service (IaaS) provider allocates virtual machines in physical machines to customers to meet their requests. The availability of cloud providers is increasingly concerned. There are several failures across the physical machines in cloud providers over the past few years, even for some high-profile cloud providers. This talk addresses challenges of resource allocation in network virtualization, including a probabilistic protection model, a prototype system to implement the model, and several computing and networking aspects.

Title: Printed Graphene Radio Frequency and
Abstract: Graphene is a two-dimensional (2D) planar layer of carbon atoms packed in a honeycomb lattice. It has been drawing a great attention from both research institutes and industry. Due to the unique chemical, thermal, mechanical, electronic and optical properties of graphene, many studies on its application for RF, microwave/millimeter-wave and THz devices and circuits have been reported. In this talk, the main focus will be on exfoliation of highly conductive graphene ink and printed graphene RF/microwave components on flexible substrates such as papers and textiles. Environmentally sustainable production of highly conductive graphene ink suitable for screen-printing technology has been developed and used for printing various low-cost, flexible, disposable antennas, transmission lines and sensors. Low-cost and environmentally sustainable printed graphene technology has a potential to penetrate to information technology into our everyday life, especially in promoting wireless connectivity, energy harvesting and the spread of IoT applications.

Title: Crossing Space, Time And Frequency Domains: Recent Developments of Four-Dimensional Antenna Arrays
to the time dimension introduced into traditional antenna arrays, 4D
antenna arrays break through the boundary of space, time and
frequency in array design. In addition to the beampatterns formed in
traditional space domain, 4D antenna arrays are also able to be used
for the synthesis of beampatterns in time and frequency domains. As
typical representatives of 4D antenna arrays, time modulated arrays
and frequency diverse arrays have been receiving much attention in
recent years. Due to their powerful beamforming ability, 4D arrays
have great potential in the applications to a variety of wireless
systems. In particular, the use of large arrays, the limited
platform and the growing secure threats promote 4D arrays to play a
crucial role in next generation wireless system. In this talk,
several recent advances on 4D antenna arrays and their applications
in wireless system are reviewed. Studies show that 4D arrays have
created many opportunities and challenges in high-efficiency
beamforming of heterogeneous arrays and physical layer secure
transmission with a lower hardware complexity.

Title: Applications of Oxide Thin Films in
functional thin films have been widely used in electronic and
optoelectronic devices due to their special physical properties and
the intercoupling nature under multiple physical fields. With the
recent development of the transfer printing technology, integration
of oxide functional thin films with flexible substrates becomes
possible. By introducing oxide functional thin films into
stretchable sensors, the performance of the sensors may be improved
while more sensing functions may be achieved. However, because large
deformation may occur in flexible sensors, the requirements for
fabrication, design, and property modulation of the stretchable and
flexible sensors are different with those of hard devices. In this
talk, our recent researches on the flexible sensors based on oxide
functional thin films will be presented. By using the transfer
printing technique, VO2 thin films have been successfully peeled off
and transfer printed onto flexible substrates. Utilizing the
mechanical design and strain coupling strategy, some flexible
sensors with high performance and stable working performance under
large deformation have been realized.
Keywords: Stretchable, flexible, oxide thin films, sensors
