This thesis explores two specific topics of discrete geometry, the multitriangulations and the polytopal realizations of products, whose connection is the problem of finding polytopal realizations of a given combinatorial structure. A k-triangulation is a maximal set of chords of the convex n-gon such that no k+1 of them mutually cross. We propose a combinatorial and geometric study of multitri...

Rock bolts, as a type of reinforcing element, are widely adopted in underground excavations and civil engineering structures. Given the importance of rock bolts, the research outlined in this paper attempts to develop a portable non-destructive evaluation method for assessing the length of installed rock bolts for inspection purposes. Traditionally, piezoelectric elements or hammer impacts were...

We compared naturally baited trapping systems to synthetically baited funnel traps and fallen trap trees for suppressing preoutbreak spruce beetle, Dendroctonus rufipennis Kirby, populations. Lures for the traps were fresh spruce (Picea spp.) bolts or bark sections, augmented by adding female spruce beetles to create secondary attraction. In 2003, we compared a naturally baited system ("bolt tr...

Abstract Glass fibre reinforced polymer (GFRP) has excellent material properties such as light weight and corrosion resistance, been applied to bridge appendages wall railings. In this case, bent L‐shaped steel members (bent members) are used at the joints with floor slab. The GFRP railings were designed consider wind loads acting on them, bolt holes for anchor bolts slotted hole ease of instal...

Following the advent of vehicle sharing online platforms such as Uber and Bolt, there has been, in recent years Nigeria, emergence home including Airbnb, Shortlet rentals, Quickteller Homes which offer serviced apartments on short-term rental basis. As a contractual arrangement with economic benefits for both hosts guests, rentals are new forms residential occupancy that is gaining preference r...

Cloud providers routinely schedule multiple applications per physical host to increase cost efficiency. The resulting interference in shared resources leads to performance degradation and, more importantly, security vulnerabilities. Interference can leak important information ranging from the placement of a service to confidential data, like private keys. We present Bolt, a practical system tha...

We construct a four-parameter family of smooth, horizonless, stationary solutions of ungauged five-dimensional supergravity by using the four-dimensional Euclidean Schwarzschild metric as a base space and “magnetizing” its bolt. We then generalize this to a five-parameter family based upon the Euclidean Kerr-Taub-Bolt. These “running Bolt” solutions are necessarily non-static. They also have th...

Homes are increasingly filled with connected devices such as wireless door locks, remotely controllable thermostats, and security cameras. Home automation systems, which used to be prohibitively expensive to average consumers, are now offered at an affordable price, accelerating the adoption of “smart” devices in the home. The advances in devices also enable researchers and practitioners to dev...
