Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Efficient and Adaptive Autonomous Guidance and Control of Planetary Rover With Improved Traction Controller and Dynamic Cost Map

Journal of Field Robotics, EarlyView.
ABSTRACT Planetary exploration is rapidly gaining importance within the space research community. Autonomous locomotion of rovers requires consideration of several mobility aspects to ensure safety, including avoiding hazardous areas that can cause the robot to become immobilized in soft soil or damaged in sharp terrains.

Don't calm down! How affective climate emerges in start‐ups

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Different types of affective climates—norms related to the experience, expression, use, and regulation of emotions—have been shown to impact organizational outcomes. However, we know less about how these climates emerge. This study investigates the emergence of affective climates through a 22‐month longitudinal multiple‐case ...

Design and simulation of railway vehicles braking operation using a scaled roller-rig [PDF]

WIT Transactions on The Built Environment, Vol 88, 2006
This paper describes how a 1:5 scale roller-rig has been recently realized at Politecnico di Torino for the simulation of railway dynamics. This paper shows that it is possible to reproduce the braking dynamics of a railway vehicle on the roller rig. For this purpose a disk-brake braking system has been designed that can be installed on the existing ...

Task co‐use and product improvement: An organization design perspective

Strategic Management Journal, EarlyView.
Abstract Research Summary Co‐using tasks—using the same task to produce more than one product—promises economies of scope. However, task co‐use also ties products together, changing a firm's task network by introducing cross‐product interdependencies. In light of these interdependencies, we identify an unrecognized downside of task co‐use for product ...

Effect of suspension systems on the physiological and psychological responses to sub-maximal biking on simulated smooth and bumpy tracks [PDF]

, 2006
The aim of this study was to compare the physiological and psychological responses of cyclists riding on a hard tail bicycle and on a full suspension bicycle. Twenty males participated in two series of tests. A test rig held the front axle of the bicycle

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

steel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...
