One advantage of smart grids is that they can reduce the peak load by distributing electricity-demands over multiple short intervals. Finding a schedule that minimizes the peak load corresponds to a variant of a strip packing problem. Normally, for strip packing problems, a given set of axis-aligned rectangles must be packed into a fixed-width strip, and the goal is to minimize the height of th...

Associate Professor, Graduate Aeronautical laboratories, California Institute of Technology, Pasadena, Calif. The tip velocity of a crack propagating through a vi scoelastic material depends on geometry, apptied toad and its history , and material properties. A consideration of the work done by the unloading tractions at the crack tip shows that, f or a large crack propagating throitgh an infin...

in this study, dynamic buckling of embedded laminated nanocomposite plates is investigated. the plates are reinforced with single-walled carbon nanotubes (swcnts) where to obtain the equivalent material properties of them, mori-tanaka model is applied. based on the sinusoidal shear deformation theory (ssdt), the motion equations are derived using energy method and hamilton's principal. the...

OBJECTIVE To assess bacteriological quality of drinking water in Punjab and to evaluate usefulness of H2S strip test in comparison with multiple tube test. METHOD Samples of water were tested using H2S strips and multiple tube test. RESULTS Maximum bacterial contamination was observed in water from domestic pumps (95.83%). Followed by tap water in rural areas of Punjab (91.30%) and tap wate...

The twin-roll strip casting process is a typical steel-strip production method which combines continuous casting and hot rolling process. The production line from molten liquid steel to the final steel-strip is shortened and the production cost is reduced significantly compared to the conventional continuous casting. The twin-roll strip casting process can produce 1-5 mm thin steel strip direct...

To study the aseismic performance after reinforcement of mortise-tenon joints folk houses with traditional Chuan-Dou style wood structure and their steel plate, test specimens joints—two for Tou joints, two Ban dovetail joints—were fabricated out hemlock, plates were utilized to reinforce one joint each type on middle part joint. By carrying pseudo-static tests building ABAQUS numerical model; ...

This paper investigates the uplift capacity of horizontal plate anchors in sand through finite element analyses and centrifuge experiments. The simulations adopt a sophisticated bounding surface plasticity model that accounts for stress- density-dependent behaviour, as well loading- fabric-related anisotropic effects sands. Failure mechanisms at peak anchor show failure occurs progressively, wi...

Micro Strip Antenna Array has been proposed with high efficiency for wireless communication. Micro strip antenna arrays are widely used in various applications like in wireless communication system, satellite communication, Radar systems, Global positioning systems, Radio Frequency Identification (RFID), Worldwide interoperability for microwave access (WiMax), Rectenna applications, Telemedicin...

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...
