Abstract:
This project develops a theoretical framework as well as software tools to support testing and verification of a Cyber-Physical System (CPS) within a Model-Based Design (MBD) process. The theoretical bases of the framework are stochastic optimization methods, and robustness notions of formal specification languages.

Abstract:
Our proposed research is motivated by two fundamental challenges that are traditionally studied in separate disciplines. The first key challenge is that in existing digital cameras, the functionalities of a camera are constrained by its size due to the optics and quantum nature of light. It remains a challenge to design a camera architecture that has both - a small form factor and has versatile functionalities, e.g.

This project has introduced a programming language, compiler, and runtime environment that enables software to control a "cyber-physical" microfluidic device in which integrated sensors and video monitoring equipment form a closed feedback loop (a). The technical contributions of the project include the design and implementation of the language, and a detailed description of the algorithms built into the compiler to enable fast decision-making in real-time in response to sensory feedback (b).

Abstract:
The artificial pancreas (AP) is a set of increasingly sophisticated devices and algorithms that will automate the delivery of insulin to patients with type--1 diabetes. While the AP concept promises to alleviate the burden posed by the self-- management of blood glucose levels, it also poses significant risks arising from a combination of external disturbances such as patient meals, physical activity, sensor errors, network delays and physiological variations.

Abstract:
We have been developing a novel virtually transparent epidermal imagery (VTEI) system for laparo-endoscopic single-site (LESS) surgery. The system uses a network of multiple, micro wireless cameras and multiview mosaicing technique to obtain a panoramic view of the surgery area. This view provides visual feedback to surgeons with large viewing angles and areas of interest so that the surgeons can improve the safety of surgical procedures by being better aware of where the surgical instruments are relative to tissue and organs.

Abstract:
Intensity modulated radiation therapy (IMRT) requires tight coordination between computational systems and the physical devices that deliver the prescribed treatment plan, making it a perfect example of cyber-physical system. The current approach to addressing tumor motion in radiation therapy is to treat it as a problem and not as a therapeutic opportunity. Existing treatment planning methods attempt to create dose distributions that are at best dosimetrically equivalent to the static case.
