Recent research on external-memory search has shown that disks can be effectively used as secondary storage when performing large breadthfirst searches. We introduce the Write-Minimizing Breadth-First Search (WMBFS) algorithm which is designed to minimize the number of writes performed in an external-memory BFS. WMBFS is also designed to store the results of the BFS for later use. We present th...

For many real-world networks only a small "sampled" version of the original network may be investigated; those results are then used to draw conclusions about the actual system. Variants of breadth-first search (BFS) sampling, which are based on epidemic processes, are widely used. Although it is well established that BFS sampling fails, in most cases, to capture the IN component(s) of directed...

Utilizing a reversible reaction between CaO and CO2, namely the calcium looping (CaL) process, is among CO2 adsorption sequestration techniques that have been intensively studied over years. While CaO-based sorbents offer numerous advantages, such as broad accessibility, low cost, relatively high theoretical uptake (0.78 gram of per CaO), its capture capability during cyclic operation degrades ...

Recordings from single neurons in the dorsal cochlear nucleus (DCN) of unanesthetized (decerebrate) cats were done to characterize the effects of acoustic trauma. Trauma was produced by a 250 Hz band of noise centered at 10 kHz, presented at 105-120 dB SPL for 4h. After a one-month recovery period, neurons were recorded in the DCN. The threshold shift, determined from compound action-potential ...

The aim of this study is to fabricate high strength calcium phosphate/ yttrium artially stabilised zirconia (Y-PSZ) composites using a simple powder pressing technique. Various compositions of hydroxyapatite and zirconia powder, ranging from 10 to 90 wt% Y-PSZ, were prepared using a wet mixing process. Ten compacts (13.5mm×3mm) were made for each composition, pressed and fired in air at sinte...

In this paper, we present a web-based automatic marking system that aims to assist the tutor in assessing the performance of students in interactive exercises related to breadth-first search (BFS) and depth-first search (DFS) algorithms. The system has been tested on a number exercises for BFS and DFS search algorithms and its performance has been compared against that of an expert tutor. The e...

Blast furnace slag (BFS) is usually regarded as a by-product of the steel industry, which can be utilized raw material for preparing BFS-based zeolite (BFSZ). In this study, BFSZ was successfully prepared from BFS using alkaline fusion-hydrothermal synthesis. Via analyses by XRD, SEM, EDX, XRF, FT-IR, elemental mapping and BET/BJH methods, crystallization almost complete at 6 h. With further in...

We aimed to assess whether arterial distensibility estimated by pulse wave velocity (PWV) and augmentation index (AI) differs between Cameroon traditional pygmies (TPs) on hunter-gather subsistence mode, contemporary pygmies who migrated to semiurban area, and the Bantou farmers (BFs) sharing the same environment. For that purpose, we recorded carotid-femoral PWV (ComplioR) in age and sex caref...

Studies which reduce cement usage, develop an alternative by partial replacement of cement with blast-furnace slag, fly ash, or such industrial byproducts, and evaluate the environmental load and economic value of concrete mixed with such are in high demand. In this study, A-BFS (Activator Blast Furnace Slag), which is mixed with an activator in order to induce early-age strength manifestation ...
