Abstract Function-as-a-Service (FaaS) is a popular programming model for building serverless applications, supported by all major cloud providers and many open-source software frameworks. One of the main challenges FaaS providing fault tolerance deployed that is, ability to mask failures function invocations from clients. The basic approach in current platforms automatically retrying invocation...

Serverless computing hides infrastructure management from developers and runs code on-demand automatically scaled billed during the code’s execution time. One of most popular serverless backend services is called Function-as-a-Service (FaaS), in which are often confronted with cloud-specific requirements. Function signature requirements, usage custom libraries that unique to cloud providers, we...

a highly convenient, selective and sensitive procedure for pre-concentration, separation and determination of sub-ppm levels of cu 2+ in aqueous samples based on modification of octadecyl silica bonded phase membrane (osbpm) disks is described using benzildithiosemicarbazone  (bdsc) as a powerful modifier. it was revealed that each loaded osbpm disk with 6.0 mg of bdsc serves as excellent bead ...

Abstract—Heavy metals are released into water, plants, soil, and food by natural and human activities. Lead has toxic roles in the human body and may cause serious problems even in low concentrations, since it may have several adverse effects on human. Therefore, determination of lead in different samples is an important procedure in the studies of environmental pollution. In this work, an ultr...

Due to importance of wheat as the most popular food, in this data article, we determined the accumulation of heavy metal levels including Cd, Co, and Cu in wheat grains in Dashtestan county, Iran. The concentration levels of heavy metals in wheat grains cultured were determined by Flame Atomic Absorption Spectrometry (FAAS).

Abstract Function-as-a-Service (FaaS) allows developers to define, orchestrate and run modular event-based pieces of code on virtualised resources, without the burden managing underlying infrastructure nor life-cycle such code. Indeed, FaaS providers offer resource auto-provisioning, auto-scaling pay-per-use billing at no costs for idle time. This makes it easy scale running represents an effec...

Two different gold-silica-based nanomaterials were prepared: (i) silica-supported gold nanoparticles (AuNP/SiO2); and (ii) gold-silica core-shell (AuNP@SiO2). Three strategies for sample treatment (S), consisting in acid treatments, employed: (S1) HNO3; (S2) HNO3 + HCl; (S3) HF HCl, applying microwave oven digestion S2 S3. From three calibration curves, slope, intercept, linear correlation coef...

The Function-as-a-Service (FaaS) paradigm has a lot of potential as computing model for fog environments comprising both cloud and edge nodes, compute requests can be scheduled across the entire continuum in fine-grained manner. When request rate exceeds capacity limits at resource-constrained edge, some functions need to offloaded toward cloud. In this article, we present an auction-inspired a...

The performance of three conventional treatments, including microwave-assisted acid digestion (MWAD), ultrasoundassisted extraction (UAE) and dry method (DAM) for determination Cu2+ Zn2+ in flaxseed meal, was evaluated. Quantification performed by flame atomic absorption spectrometry (FAAS) differential pulse anode stripping voltammetry (DPASV). TheMWAD treatment with both concentrated HNO3 (CA...
