Abstract:
Activity recognition enables ambient assisted living applications to provide activity-aware services to users in smart homes. Despite significant progress being made in activity recognition research, the focus has been on simple activity recognition leaving composite activity recognition an open problem. For instance, knowledge-driven activity recognition has recently attracted increasing attention but mainly focused on simple activities. This paper extends previous work by introducing a knowledge-driven approach to recognition of composite activities such as interleaved and concurrent activit

A model defined at the ply scale to predict the failure of laminated composites for static or fatigue loading is proposed. The model describes the loss of strength in the fiber direction for a significant level of transverse damage. This meso-scale model has been characterized on woven ply laminates used for rotorcraft dynamic components, such as glass/epoxy of Starflex®, carbon fiber/epoxy, and carbon fiber/PEEK of H160 main rotor hub. Failure behavior prediction at coupon level has been validated regarding static and fatigue failure mode in tension for epoxy resin woven ply laminates. Charac

Abstract:
Robust and reliable structural design necessitates numerous tests for rotor blades and rotor heads. The only way to be sure regarding analysis methods containing many assumptions and unknowns is to conduct dedicated tests simulating the operational case as close as possible. Within this context, a series of test activities have been planned so as to provide structural integrity verification of rotor system. In order to evaluate structural and aeromechanical performance of the rotor system, a Whirl Tower is designed and manufactured indigenously in TAI. In this study, an assessment on Whirl Tow

Amateur rocket structures are usually made of composite materials, wood or aluminium, their internal geometries and interfaces are usually restricted by the available manufacturing techniques. However, with the appearance of the additive manufacturing sector new possibilities arise for the design of the structures and its complexity. In this paper a PA-12 and glass fibre composite structure for the Phobos rocket is designed which the UPC Space Program aims to use to participate in the European Rocketry challenge. The Phobos rocket structure is designed and optimized to be fabricated using addi

Abstract:
Cold in-place recycling (CIR) involves the recycling of the asphalt portions (including hot-mix asphalt and chip, slurry, and cape seals, as well as others) of a flexible or composite pavement with asphalt emulsion or foamed asphalt as the binding agent. Full-depth reclamation (FDR) includes the recycling of the entire depth of the pavement and, in some cases, a portion of the subgrade with asphalt, cement, or lime products as binding agents. Both processes are extensively utilized in Illinois. This project reviewed CIR and FDR projects identified by the Illinois Department of Transportation (

Transportation, wholesaling, and retailing activities are a significant segment of economic activity in many economies. The magnitude of these activities can vary greatly between products, users, and regions. However, in most applied general equilibrium (AGE) analyses, these marketing activities are not tied to specific commodities. This paper develops a model framework and database that incorporates domestic marketing margins on domestic and imported goods going to final demand or used as intermediate inputs, and margins on exports, into the standard GTAP Model.

Abstract:
The Geo-mapping for Energy and Minerals program addressed four questions related to the lower Paleozoic succession of the Arctic Islands that were identified as key deficiencies in regional geological knowledge: 1) geochemical and geological data were not fully digital or available; 2) there were gaps in information on petroleum systems; 3) there was no geological map for the northwestern part of Victoria Island; and 4) the geological history of the Pearya composite terrane on northern Ellesmere Island was unclear.

Abstract:
The vadose (unsaturated) zone forms a major hydrologic link between the ground surface and underlying aquifers. To understand properly its role in protecting groundwater from near surface sources of contamination, one must be able to analyze quantitatively water flow and contaminant transport in variably saturated subsurface environments that are highly heterogeneous, often consisting of multiple geologic units and/or high and/or low permeability inclusions.

Within this specific contribution we focus on a group of structural transformations that take place within local production systems, namely clusters and districts. This change represents one of the responses of the western economies to the challenges put forth by the emerging powers (e.g. China and the likes). The central idea of this work revolves around the concept of ‘cluster’, which created a heated debate over the past two decades. In fact, some stressed the relevance of the width of the ‘interconnected activities and institutions’ that compose a specific cluster, whereas others tended to
