Thermal electric ice-core drills: history and new design options for intermediate-depth drilling
Ice coring of temperate and polythermal glaciers demonstrates some limitations of most electromechanical (EM) and thermal electric (TE) drills. Most TE drills are heavy, require a heavy power system, work slowly and cannot operate in boreholes going through the cold–temperate ice transition. Antifreeze thermal electric drills (ATED) are capable of operating in polar ice caps, polythermal and te...

متن کاملMulti-week MILP scheduling for an ice cream processing facility
This paper presents a multi-week mixed integer linear programming (MILP) scheduling model for an ice cream processing facility. The ice cream processing is a typical complex food manufacturing process and a simplified version of this processing has been adapted to investigate scheduling problems in the literature. Most of these models only considered the production scheduling for a week. In thi...
متن کاملComparative Analysis of Drills for Composite Laminates
The characteristics of carbon fibre reinforced plastics allow a very broad range of uses. Drilling is often necessary to assemble different components, but this can lead to various forms of damage, such as delamination which is the most severe. However, a reduced thrust force can decrease the risk of delamination. In this work, two variables of the drilling process were compared: tool material ...
متن کاملA framework for goal-drivenpair drills
This paper proposes a framework for goal-driven pair drills. What distinguishes these drills fromordinary controlled drills lies in themotivating characteristics such as clear goals, outcomes, and communicativeness. With these features present, goal-drivenpair drills encourage learners to processmultiple layers of language skill aspects. A brief review of the relevant theoretical and empirical ...
