Long-haul Heavy Goods Vehicles (HGVs) are a significant source of carbon emissions, accounting for around 5% the UK's total. If UK is to meet its net zero mandate, it vital have zero-emissions alternative traditional diesel-powered HGVs that cost-effective and widespread in 2040s. This paper presents technoeconomic comparison two solutions decarbonising long-haul heavy goods vehicles UK: electric with an road system (overhead catenary) along major network, fuel cell public refuelling...

SUMMARY The fields of modular reconfigurable robotics and programmable matter study how to compose functionally useful systems from configurations modules. In addition the external shape a module configuration, internal arrangement modules bonds between them can greatly impact relevant mechanical properties such as load bearing ability. A fast method evaluate property aids search for an achieving desired space possible grows combinatorially. We present approximate where are represented with...

Modular robotic systems can form arbitrary shapes that best suit task requirements. Such a system comprised of microscale components could reconfigurable microstructures or high resolution physical prototypes. This paper presents methods aimed at miniaturization this programmable matter towards the millimeter scale smaller. The Right Angle Tetrahedron Chain Externally-actuated Testbed (RATChET) be folded into 3D shapes. tetrahedron shaped modules are designed to have limited complexity and...

An energy efficient joint-locking mechanism that works in conjunction with the main actuator of a robot module is presented. The will enable chain-style modular reconfigurable robots to perform wide array tasks such as dynamic motion and bio-inspired locomotion while consuming less power. design process for developing this presented, analysis provided. This ideal systems, but can be modified suit many applications. A prototype developed outperforms comparable devices those utilize...

Micro air vehicles have emerged as a popular option for diverse robotic and teleoperated applications because of their inherent stealth, portability, disposability. In this work, we adopt system-level perspective the development rotary-wing micro vehicle propose new design that utilizes gyroscopic dynamics attitude control. Unlike traditional where control moments are generated by aerodynamic surfaces, proposed will leverage existing angular momentum its rotating components to generate...

This study estimates the dose-response relationship between Body Mass Index (BMI) and crash risk in commercial motor vehicle operators. Intake data was collected on 744 new truck drivers who were training for their driver's licenses at a school operated by cooperating trucking firm during first two-week phase of instruction. Drivers then followed prospectively job using firm's operational two years, or until employment separation, whichever came first. Multivariate Poisson regression Cox...

Purpose The recent coronavirus pandemic created uncertainty across most markets. This has resulted in many valuations being reported with caveats warning that they are uncertain. However, valuers and their clients remain unclear as to what these warnings supposed convey why required by valuation standards, including the International Valuation Standards. purpose of this paper is explain how recognition need for disclosures developed over past 25 years such can enhance overall trust...

Purpose Market value is an estimation of price in the market. It exchange. The valuer's role to determine appropriate approach, method and use right model achieve this aim as best possible. However, underpinning all valuations property analysis are valuation standards definitions. This paper looks at definition market how some participants may misunderstand or even misrepresent it. particularly true when there a downturn Design/methodology/approach practice briefing overview it often misused...

A bistable brake mechanism can be beneficial to the development of an energy efficient module for a modular reconfigurable robot. These robots are comprised many repeated units. To date, research efforts have focused on increasing specific torque expand capabilities robots. In this work, we present continued joint-locking mechanisms, specifically piezoelectric actuator and compliant transmission. The design manufacturing is presented along with model predicting static dynamic behavior...

Purpose The aim of this practice briefing is to provide clarity on property valuations provided for secured lending. principal basis valuation market value but there confusion when and where it appropriate or inappropriate a with an assumption restricted marketing period, sometimes referred as “forced sale”. This examines the nature problem steps which valuer can take advice consistent standards. Design/methodology/approach overview role standards providing lending specifically what do asked...
