Since highway improvement project selection requires screening thousands of road segments with respect to crashes for further analysis and final project selection, we provide a two-step project selection methodology and describe an application case to demonstrate its advantages. In the first step of the proposed methodology, we will use odds against observing a given crash count, injury count, ...

Initiating flight is challenging, and considerable effort has focused on understanding the energetics and aerodynamics of take-off for both machines and animals. For animal flight, the available evidence suggests that birds maximize their initial flight velocity using leg thrust rather than wing flapping. The smallest birds, hummingbirds (Order Apodiformes), are unique in their ability to perfo...

Research on the scrape-off-layer plasma of the Alcator C-Mod Tokamak is reviewed. The research has focused on understanding the transport of energy and particles both parallel and perpendicular to the magnetic field. Large differences between the inboard, high-field side scrape-off-layer and the outboard, low-field side are found. On the outboard side large levels of anomalous cross-field trans...

In this work, the off-state characteristics of AlScN/GaN high electron mobility transistors (HEMTs) grown by metalorganic chemical vapor deposition (MOCVD) were studied and directly compared to an AlGaN- AlN-HEMT in same MOCVD. Pinch-off instability leaky capacitive measurements observed for AlScN-based HEMTs, which was correlated with a higher ideality factor lower effective potential barrier ...

A NAND flash memory senses a cell current in the range of tens nA, which is smaller than other nonvolatile memories read operation. Because small current, it difficult to improve latency and accuracy The improvement has been major challenge for all-bit-line (ABL) sensing architecture because BL coupling capacitance caused by off limits pre-charge time. In this paper, high-speed scheme with an o...

This paper is part of a wide debate and critical reflection on the use of ICT in nursery schools, and focuses on the use of station KidSmart in the classroom to enhance scientific learning within the logical-mathematic field. The study is organized as follows: after presenting the institutional setting within which ICT has been introduced in Italian nursery schools, some considerations are made...

Maintaining consistency is a difficult challenge in crowd-powered systems in which constituent crowd workers may change over time. We discuss an initial outline for Chorus:Mnemonic, a system that augments the crowd’s collective memory of a conversation by automatically recovering past knowledge based on topic, allowing the system to support consistent multi-session interactions. We present the ...

Asynchronous discussion fora all the more become part of the educational process of distance education. The goal of this research is the study of the educational techniques of Brainstorming and Snowballing to their utilisation in the frame of a distance education forum, both as far as participation and creation of learning environment and also educational effectiveness are concerned. This resea...
