Geopolymer concrete is an effective solution for widely limiting the negative environmental impacts of cement manufacturing world. In this research, polypropylene fibers (PP fiber) with various volume fractions, lengths, reinforcing index as well water-binder ratios (WBR) were mixed into geopolymers to evaluate effect on their FrT (fracture toughness). A total 28 experimental groups different fiber considered. three-point bending fracture examination, deformation and displacement fields...
We found that interactive services at Bing have highly variable datacenter-side processing latencies because their consists of many sequential stages, parallelization across 10s-1000s servers and aggregation responses the network. To improve tail latency such services, we use a few building blocks: reissuing laggards elsewhere in cluster, new policies to return incomplete results speeding up by giving them more resources. Combining these blocks reduce overall is non-trivial for same amount...
This study investigates the utilization of polyethylene fiber (PEF) and microsilica for production high-strength high-toughness geopolymer concrete (HSHTGC). The influence PEF factor or content on fracture parameters strength is evaluated, while acoustic emission (AE) response crack morphologies are employed to validate performance results. By combing with microsilica, this successfully prepared HSHTGC compressive exceeding 90 MPa, significant multi-cracking characteristics, as well high...
Large Language Models (LLMs) have revolutionized text generation, making detecting machine-generated increasingly challenging. Although past methods achieved good performance on pure text, those detectors poor distinguishing machine-revised (rewriting, expansion, and polishing), which can only minor changes from its original human prompt. As the content of may originate prompts, often involves identifying distinctive machine styles, e.g., worded favored by LLMs. However, existing struggle to...
This paper presents a scheduling model for class of interactive services in which requests are time bounded and lower result quality can be traded shorter execution time. These applications include web search engines, finance servers, other interactive, on-line services. We develop an efficient algorithm, Zeta, that allocates processor among service to maximize the minimize variance response.
Silicone rubber (SiR) is used as an insulating material for cables installed in a nuclear power plant. Gamma rays irradiated SiR sheets various periods at temperatures of 145 and 185 °C, the resultant changes were analyzed by examining complex permittivity spectra surface potential decay characteristics. Three different processes, namely, instantaneous polarization, electrode polarization due to accumulation ions form double charge layers dielectric/electrode interfaces, DC conduction caused...
Polyimide has excellent electrical, thermal, and mechanical properties is widely used as a dielectric material in electrical equipment electronic devices. However, the influencing mechanism of sample thickness on breakdown polyimide not been very clear until now. The direct current (DC) function were investigated by experiments simulations space charge modulated (SCEB) model transport molecular displacement (CTMD) model. experimental results show that field decreases with an increase form...

Dielectric energy storage capacitors have advantages such as ultra-high power density, extremely fast charge and discharge speed, long service lifespan are significant for pulsed system, smart grid, electronics. Polypropylene (PP) is one of the most widely used dielectric materials capacitors. It interest to investigate how improve its electrical breakdown strength by nanodoping influencing mechanism on properties polymer nanocomposites. PP/Al₂O₃ nanocomposite with various weight fraction...
In this paper we introduce a new notion of collective tree spanners. We say that graph G=(V,E)admits system $\mu$ additive r-spanners if there is T(G) at most spanning trees G such for any two vertices x,y T\in \cT(G) exists d_T(x,y)\leq d_G(x,y)+r. Among other results, show chordal graph, bipartite or cocomparability admits log2n 2-spanners. These results are complemented by lower bounds, which 1-spanners must have $\Omega(\sqrt{n})$ some graphs and $\Omega(n)$ graphs. Furthermore,...
In this paper we study collective additive tree spanners for families of graphs that either contain or are contained in AT-free graphs. We say a graph G=(V,E) admits system μcollective r-spanners if there is ${\cal T}(G)$ at most μ spanning trees G such any two vertices x,y $T\in {\cal exists dT(x,y)≤ dG(x,y)+r. Among other results, show have 2-spanners (whereas trapezoid do not admit 2-spanner). Furthermore, based on collection trees, derive compact and efficient routing scheme those Also,...
Background The performance of existing image-based training models in evaluating bowel preparation on colonoscopy videos was relatively low, and only a few used external data to prove their generalization. Therefore, this study attempted develop more precise stable AI system for assessing video. Methods We proposed named ViENDO assess the quality, including two CNNs. First, Information-Net identify filter out video frames unsuitable Boston scale (BBPS) scoring. Second, BBPS-Net trained...
Zinc telluride thin films were deposited by thermal evaporation method on n-type Si substrate. The electrical properties of these investigated with special emphasis the effects a depositing temperature from 520°C to 560°C various annealing temperatures rapid (RTA) technique. Structural analysis through X-ray diffraction (XRD) was sensitive deposition conditions and treatment. Crystallinity, carrier concentration, sheet resistance, resistivity mobility are shown be dependent treatments.
In this article, we propose a method to calculate the density of deep traps formed in interaction zones based on mesoscopic structure and double-electric layer polymer nanocomposites. A space-charge modulated breakdown model is then utilized investigate electrical property its relation zones. The that around independent suppressed spacecharge accumulation distortion electric field, leading improvement dc strength.
