As voice, multimedia, and data services are converging to IP, there is a need for a new networking architecture to support future innovations and applications. Users are consuming Internet services from multiple devices that have multiple network interfaces such as Wi-Fi, LTE, Bluetooth, and possibly wired LAN. Such diverse network connectivity can be used to increase both reliability and perfo...

Volatile FPGAs, the dominant type of programmable logic devices, are used for space, military, automotive, and consumer electronics applications which require them to operate in a wide range of environments. Their continuous growth in both capability and capacity now requires significant resources to be invested in the designs that are created for them. This has brought increased interest in th...

Flying a quadrotor helicopter requires at least a means for stabilization control. Although efficiently stabilizing a quadrotor is itself an extensive research field, adding autonomous control poses even more challenging problems: the underlying quadrotor platform must provide sufficiently precise sensors with high update rates, the mechanical parts should not incur large update delays, and the...

Self-reported data collected via surveys are a key input into a wide range of research conducted by economists. It is well known that such data are subject to measurement error that arises when respondents are asked to recall past utilisation. Survey designers must determine the length of the recall period and face a trade-off as increasing the recall period provides more information, but incre...

Design theory and methodology is an emerging area of research. It supports understanding of the design process and its automation in the form of Computer Aided Design. This paper is focused on design methodologies used in computer aided design systems. Several typical cases are reviewed. They are: Computational Model for Hierarchical Mechanical System Design, Optimal Directed Design Model, Know...

Current ambulance designs are ergonomically inefficient and often times unsafe for practical treatment response to medical emergencies. Thus, the patient compartment of a moving ambulance is a hazardous working environment. As a consequence, emergency medical services (EMS) workers suffer fatalities and injuries that far exceed those of the average work place in the United States. To reduce inj...

We describe a new project, the Dark Energy Survey (DES), aimed at measuring the dark energy equation of state parameter, w, to a statistical precision of ~5%, with four complementary techniques. The survey will use a new 3 sq. deg. mosaic camera (DECam) mounted at the prime focus of the Blanco 4m telescope at the Cerro-Tololo International Observatory (CTIO). DECam includes a large mosaic camer...

The paper addresses design/building frameworks for some kinds of tree-like and hierarchical structures of systems. The following approaches are examined: (1) expert-based procedure, (2) hierarchical clustering; (3) spanning problems (e.g., minimum spanning tree, minimum Steiner tree, maximum leaf spanning tree problem; (4) design of organizational " optimal " hierarchies; (5) design of multi-la...

As projector units become smaller, brighter and more energy conserving, they are bound to become an integral part of many mobile phone models in the future. We lay out and discuss the design space of interactions and applications enabled by such devices. Moreover, we focus on the implications of hardware design, discuss possible interaction concepts, describe the most relevant applications area...

The gain-scheduling approach is perhaps one of the most popular nonlinear control design approaches which has been widely and successfully applied in fields ranging from aerospace to process control. Despite the wide application of gain-scheduling controllers and a diverse academic literature relating to gain-scheduling extending back nearly thirty years, there is a notable lack of a formal rev...
