In this paper we present a new approach for cooperation between mobile smart objects and projector-camera systems to enable augmentation of the surface of objects with interactive projected displays. We investigate how a smart object’s capability for self description and sensing can be used in cooperation with the vision capability of projector-camera systems to help locate, track and display i...

This invited paper briefly describes our progress in developing a resilient multi-spectral image analysis capability for remote sensing applications. This capability is intended to allow image streams from a collection of distributed sensors to be disseminated and interpreted by a group of analysts, while under information warfare attack. There are five component technologies that we are develo...

The paper proposed a new scheme for parallel implementation of compressive sensing based SAR imaging on GPU with Iterative Shrinkage/Thresholding algorithm. To get a faster recovery speed, we modified the existed IST algorithm structure, and realized the fast implementation on GPU. The experiment result shows that parallel computing capabilities of GPU have a significant speedup in comparison w...

The LH Systems ADS40 airborne digital sensor fulfils photogrammetric and remote sensing requirements. The new sensor is not only a camera to acquire attractive pictures: it is the next fully digital generation of measurement device for airborne photogrammetry and remote sensing. The accuracy of the lens and focal plane system under flight conditions (pressure and temperature) is described and a...

The overall objective of this program is the investigation and development of innovative concepts and solutions to the challenges presented by the envisioned availability of very large numbers of heterogeneous sensors each of which is limited in sensing capability, power, computation, and communication. As we see it, these challenges can be grouped into three interrelated intellectual themes (I...

We report a one-pot, two-step strategy to synthesize fluorescent gold nanodots (AuNDs) co-modified with 1-(10-mercaptodecyl)-5-methylpyrimidine-2,4-dione (TSH) and 11-mercaptoundecanoic acid (MUA) through a ligand exchange reaction and demonstrate their capability of selective sulfide sensing in aqueous media on the basis of fluorescence recovery.

Wireless monitoring has emerged in recent years as a promising technology that could greatly impact the field of structural monitoring and infrastructure asset management. This paper is a summary of research efforts that have resulted in the design of numerous wireless sensing unit prototypes explicitly intended for implementation in civil structures. Wireless sensing units integrate wireless c...

The bottom-up construction of cell-sized compartments programmed with DNA that are capable of sensing the chemical and physical environment remains challenging in synthetic cell engineering. Here, we construct mechanosensitive liposomes with biosensing capability by expressing the E. coli channel MscL and a calcium biosensor using cell-free expression.

Wireless Sensor Networks (WSNs) consist of thousands of tiny nodes having the capability of sensing, computation, and wireless communications. Many routing, power management, and data dissemination protocols have been specifically designed for WSNs where energy consumption is an essential design issues. Since wireless sensor network protocols are application specific, so the focus has been give...

This paper demonstrates the chemical sensing capability of a miniaturized fiber inline Fabry-Pérot sensor fabricated by femtosecond laser. Its accessible cavity enables the device to measure the refractive index within the cavity. The refractive index change introduced by changing the acetone solution concentration was experimentally detected with an error less than 4.2×10.
