Coverage is a task, where a robot is to move about a given a target area until every point in it is visited. Many efficient coverage algorithms cannot be used in practice, because they assume accurate movements by the robot; unfortunately, real robots have navigational errors. A standard costly solution is to utilize a robot that continuously localizes, so as to make course corrections. In this...

A Mobile Ad-Hoc Network (MANET) is a group of wireless, mobile, battery-powered clients and servers that autonomously form temporary networks. Three data communication modes can be provided in a MANET, data broadcast, data query, and peer-to-peer messaging. Currently, no MANET data communication protocol provides the ability to use all MANET data communication modes. The objective of this resea...

A series of RANS-based aerodynamic shape optimization for an 800-passenger blended-wing-body aircraft is performed. A gradient-based optimization algorithm and a parallel structured multiblock RANS solver with Spalart–Allmaras turbulence model are used. The derivatives are computed using a discrete adjoint method considering both frozen-turbulence and full-turbulence assumptions. A total of 274...

Many production environments require economical cutting of onedimensional items according to bills of materials from objects of several standard lengths. However, even with optimised cutting substantial trim loss may occur. This trim loss should not be regarded as waste. It is returned to store and can be reused in future optimisations. Optimisation of packing linear items into standard lengths...

The new Lcica RM 2165 automatic, heavy-duty microtome has an advanced step motor that permits an exact specimen feed and reproducible sectioning results. Features include 70 mm vertical stroke length, unique step trim function, and programmable specimen retraction. Technical features include a handwheel rocking sectioning mode; the motorized specimen feed can be linked to change the handwheel t...

We consider a one-dimensional cutting stock problem (CSP) in which the stock widths are not used to fulfill the order but kept for use in the future for the industrial-use paper production. We present a new model based on the flexible stock allocation and trim loss control to determine the production quantity. We evaluate our approach using a real data and show that we are able to solve industr...

Stability and control of rotors at high advance ratio are considered. Stability of teetering, articulated, and gimbaled hub types is considered with a simple flapping blade analysis. Rotor control in autorotation for teetering and articulated hub types is examined in more detail for a compound helicopter (rotor and fixed wing) using the comprehensive analysis CAMRAD II. Autorotation is found to...

Data recovery techniques for platter-based disk drives have remained rather static due to the dominance of the hard disk for the last two decades. Solid State Disk drives have differing storage and recall functionality from platter-based disks and require special care when attempting data recovery. Manufacturers have varying implementations of garbage collection in each drive, which affects the...
