We propose a new type of input for mobile devices by sensing forces applied by users to device casings. Deformation of the devices is not necessary for such “force gestures” to be detectable. Our prototype implementation augments an ultra-mobile PC (UMPC) to detect twisting and bending forces. We describe examples of interactions using these forces, employing twisting to perform application swi...

We prove that, given any $n\geqslant 3$ and $2\leqslant q\leqslant n-1$, there is a closed $n$-manifold $M^{n}$ admitting chaotic lamination of codimension $q$ whose support has the topological dimension ${n-q+1}$. For $n=3$ $q=2$, such laminations can be represented as nontrivial 2-dimensional basic sets axiom A flows on 3-manifolds. show that are two types compactification (called casings) fo...

Brookhaven National Laboratory was requested to conduct a literature survey for the best available cement to use in the proposed casing patch as part of the Geothermal Drilling Organization (GDO) project on remediation of deformed casings. A total of 50 wells has been identified with deformed production casing in Unocal’s portion of The Geysers geothermal field. Reduced internal diameter and ca...

The black layer is digitized from a USGS topographic map digitized at 1000 dpi. The connected components of this layer are analyzed and separated into line art, text, and icons in two passes. The paired street casings are converted to polylines by vectorization and associated with street labels from the character recognition phase. The accuracy of character recognition is shown to improve by ta...

This paper is concerned primarily with screw conveyors with fully enclosed tubular casings. The throughput, torque and power are significantly influenced by the vortex motion of the bulk solid being conveyed. The vortex motion, together with the degree of fill, govern the volumetric efficiency and, hence, the throughput. This, in turn, influences the torque, power and conveying efficiency. A th...

Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades. Thus steam flowing through the turbine passes alternately through fixed and moving blades with the fixed blades directing the steam...

Industry recognizes wireless sensor networks as one of the next major technical and economical shifts in automation and control systems. Industrial applications need performance assurances of wireless communication, which is hard to attain given the variability of the environment where such applications are deployed. In this paper, we quantify the impact of environmental conditions, namely temp...

Radioactive isotopes were first applied to investigate industrial problems some sixty years ago and since then, there has been a continuous expansion in their usage. The oil industry, in particular, was quick to recognise the potential usefulness of this technology and one of the earliest industrial studies in the literature is concerned with the use of radioactive material to tag the cement of...
