A goal has been set to make a contribution to society in challenging global warming, especially to reduce the emissions of CO2, by developing a hybrid system that drives the swing device of a hydraulic excavator by electric drive, to significantly reduce fuel consumption. Reductions in emissions of greenhouse gases are not making satisfactory progress and regulation of the construction industry...

In this paper, for the first time, notion of multi complex numbers and number valued inner product is introduced in linear (vector) space. Starting from definition, some basic properties spaces are studied along with examples. Multi parallelogram law polarization identity established

Since it was introduced to its market in 1995, the WA600-3 has won a high reputation among users in various fields. However, more than ten years have passed since the last model changes and a review has become necessary reflecting changes in user needs and model changes of competing machines. Activities have been undertaken to meet social regulations such as Tier-3 exhaust gas regulation to be ...

Configuration systems have widely been applied to efficiently address the customization responsiveness squeeze of companies dealing with Mass Cus-tomization. Over time, several frameworks have been introduced to enable their systematic planning , analyses, development and implementation. Traditional research has thereby either focused on defining modelling techniques for the configuration model...

We estimated the speed of Zika virus introduction in Brazil by using confirmed cases at the municipal level. Our models indicate a southward pattern of introduction starting from the northeastern coast and a pattern of movement toward the western border with an average speed of spread of 42 km/day or 15,367 km/year.

Dengue is a public health problem in the tropics and subtropics. There are several vaccine candidates in clinical development. However, there may be gaps in the new vaccine introduction after vaccine licensure before it becomes available in developing countries. In anticipation of the first dengue vaccine candidate to be licensed, Dengue Vaccine Initiative (DVI) and, its predecessor, Pediatric ...

T his paper derives from an undergraduate course in chemical product design which we ®rst taught in 1998/9 and are still in the process of developing. We are in the process of writing a text book to accompany such courses. We explain our approach to chemical product design and why the subject is important. The distinctive features of product design (particularly in contrast to process design, a...

Multiple spin systems allow for the presence of quantum coherence and spin-spin coupling interactions. Traditionally, density operator formalism is used to describe these systems; however, the use of this formalism often clouds intuition making it a cumbersome tool. Here we introduce a third formalism constructed from the density operator formalism with a direct connection to a non-classical in...
