Towards management of construction site Big Data
Published in Sergio Barile, Raul Espejo, Igor Perko, Marialuisa Saviano, Francesco Caputo, Cybernetics and Systems, 2018
The research method was designed to include both a laboratory (lab) and a field experiment. The lab experiment was designed to be a replication of the field experiment. In the lab, the equipment was tested and validated. The field experiment took place on a real construction site setting where the Vinarium lookout tower (see Figure 55.2b) was built (reinforced concrete building) and assembled (steel columns assembly). The technical framework for collection of Big Data on the construction site (Figure 55.1), designed in our research, is based on the conceptual model, which contains three subsystems: material flow monitoring, image-based tracking, and personal on-site observations (Podbreznik & Rebolj, 2005; Rebolj, Čuš Babič, Magdič, Podbreznik, & Pšunder, 2008).

Training is not the only solution, however, and road design also has a key role to play. In the case of cyclists, for example, dedicated bicycle lanes on arterial roads and at intersections, along with the removal of parking facilities on the side of shopping strips, would remove the preoccupation with hazards off to the left of the road, freeing up resources to focus on the road itself. Further, at intersections, road signage encouraging drivers to be on the lookout for motorcyclists and cyclists filtering up the inside and outside of traffic queues could provide benefit. Since motorcyclists are often trained to filter, training them to filter at low speeds whilst anticipating lane crossing movements by traffic ahead would also be useful.

Year 1 sampling was initiated in summer 1992. For logistical (manpower, transportation) reasons, only streams between 44 and 45 degrees north latitude (roughly between the cities of Salem and Eugene, OR) in the two study ecoregions were considered for sampling (Figure 1). Stream segments were defined as the length of stream between “blue line” confluences or between a confluence and the headward extent of the blue line. The stream segments to be sampled were chosen in two steps. The first step involved obtaining a randomized systematic sample of stream segments using the approach developed for the National Stream Survey (Kaufmann et al., 1988, 1991). A clear acetate sheet dotted with a grid of rectangular points was randomly dropped on top of the 100,000 scale USGS topographic maps for each ecoregion. The stream segment “hit” by following the topographic fall line down from each of the acetate grid point was selected as a potential field sampling segment. This procedure resulted in a set of about 200 potential Cascade and Valley stream segments for sampling. The second step involved reduction of the sample size to a workable field-study size. Initial segments were assigned to either the small or large size class based on stream order and randomized within each of the four ecoregion/size class strata. The first four wadeable streams on the randomized list in each stratum, for which site access could be obtained, were selected for field sampling. The exact sampling location on each stream segment was chosen using a random number table. In addition to the 16 randomly selected streams, two hand-picked stream sites (Lookout and Mack Creeks) in the H.J. Andrews Experimental Forest/Cascade Mt. Long-term Ecological Research area were also sampled to allow comparison to a large database available for these sites. Mack Creek is a first-order stream and Lookout Creek is a relatively large third-order stream.
Paleomagnetism of the Carboniferous Gresford Block, Tamworth Belt, southern New England Orogen: minor counter-clockwise rotation of a primary arc segment
Published in Australian Journal of Earth Sciences, 2020
Anisotropy of magnetic susceptibility is more pronounced in some of the volcanic flows than in the tuffaceous beds. Highest degrees of anisotropy (P, Supplementary papers, Tables S9 and S10 for corrected degree of anisotropy P′) are observed in the Vacy Ignimbrite Member (10.6%), Matthews Gap Dacitic Tuff Member (9.7%), Breckin Ignimbrite Member (9.5%), Paterson Volcanics (8.9%) and two directly overlying tuffaceous beds of the Seaham Formation (6.1%), MCIM (5.8%), Mirannie Volcanic Member (5.0%), Mowbray Formation (3.5%), Vineyard Lookout Formation (3.5%), Lambs Valley Ignimbrite Member (3.2%) and Mount Rivers Ignimbrite Member (2.2%). The Mount Durham Tuff Member shows surprisingly low anisotropy (0.1–0.7%), generally lower than a tuffaceous bed and tuff of the Newtown Formation (0.3–0.4%) and tuffs (1.5–3.8%) and tuffaceous beds/varves (0.6–6.0%) of the Seaham Formation.
Estimating Forest Fire Losses Using Stochastic Approach: Case Study of the Kroumiria Mountains (Northwestern Tunisia)

In most cases, forest fires have an anthropogenic origin, whether voluntary or involuntary (Renard et al. 2012). Fire ignitions recorded tend to be clustered around transportation networks and near urban areas (Catry et al. 2009; Martínez et al. 2009). We therefore considered four variables to describe the human footprint: (1) distance to road networks, (2) distance to settlements, (3) distance to lookout posts (i.e., watch tower), and (4) distance to fire-walls. Furthermore, as the Tunisian-Algerian border plays an important role in the spatial distribution of forest fires, we also computed, using Euclidean distance tool, the thematic layer “distance to the Tunisian-Algerian border.”
The CSU engineering model: educating student engineers through PBL, WPL and an online, on demand curriculum

Clients bring a wide range of projects, across the full spectrum of the design lifecycle. We have had detailed specifications that needed detailed design solutions, which were intended for construction; such as the design of a judges’ box for a local racetrack, or a viewing platform for a heritage-listed scenic lookout. We have had repair and remediation projects such as for the welcome sign and statues for a small regional town. We have also had ideation projects with a client who wanted to know what is possible in converting a disused grain silo into residential apartments.
