Negative Poisson ratio (NPR) materials based on a re-entrant honeycomb structure expand in the direction perpendicular to an externally exerted tension. This feature makes NPR structures attractive for use in microsensors and actuators as versatile motion transformers. When implemented in microdevices, where slender and flexible micromachined elements are widely used, the NPR material can toler...

Bumblebees (Bombus terrestris) use information from surrounding electric fields to make foraging decisions. Electroreception in air, a nonconductive medium, is a recently discovered sensory capacity of insects, yet the sensory mechanisms remain elusive. Here, we investigate two putative electric field sensors: antennae and mechanosensory hairs. Examining their mechanical and neural response, we...

The truss upgrade for the Calgary Municipal Building posed a unique challenge live tracking of structure’s reaction to pre-loadings, welding operations, and removal preloads. authors, therefore, devised method special case deflection monitoring, with pre-condition having displacement-free location available where cameras could be installed. dust other construction material would appear above sp...

Aluminum alloys are used in many applications in which the combination of high strength and low weight is attractive; ship building, air frame, transportation industry etc. are some areas in which the low weight can be significant value. Friction stir welding (FSW) is a new welding technique particularly well suited to aluminum alloys though this technique is also used for other materials. Fric...

The (extra)ordinary gauge mediation extension of deflected AMSB scenarios can be interesting because it accommodate together the deflection in Kahler potential and superpotential. We derive analytical expressions for soft SUSY breaking parameters such EOGM with presence both types deflections. Landau pole proton decay constraints are also discussed.

Convincing evidence for the interaction between jets and their environments has been found inmany extragalactic radio sources. In some radio galaxies these interactions appear to cause the jet to be deflected, not completely stopped or disrupted. This paper presents a simple model which accounts for jet deflections with oblique shocks in a relativistic flow. Using the model in conjunction with ...

This study aims to determine the service load capacity of existing truss construction using wood material. Analysis and calculations were performed on tensile members, compression members,connection, deflections that occur standard SNI 7973 : 2013. The needs be analyzed for its overall strength so function building can maximized. results research obtained value in carrying was due connection wi...
