Research on the relationship between the scattering contribution and physical factors of the reference radiation regulated by ISO 4037–1

The minimum dimension of a gamma radiation reference field was not clearly defined in the new ISO 4037. u20131:2019 version, causing the construction of a minitype gamma reference radiation field lacks scientific evidence. This paper conducted the analysis on the connection between the scattering contribution and physical characteristics of the reference radiation tightly controlled by ISO 4037:u20131. Based on Monte Carlo's simulation results, LS-SVM was used to build the relational model based on the Monte Carlo method's simulation of physical variables and scattering results. By PSO algorithm, the minimum dimension of collimated reference radiation field is obtained. Then the minimum dimension of collimated reference radiation field is obtained.

The importance of tetrel bonding interactions with carbon in two arrestive iso-structural Cd(ii)–Salen coordination complexes: a comprehensive DFT overview in crystal engineering

Two preeminent iso-structural Cdu2013Salen complexes were synthesized and structurally described. In a reassessed version of the DFT, unique tetrel bonding interactions involving the CH3 group have been documented. We present the serendipitous synthesis of two remarkable isostructural Cd [L2Cd422] in the presence of H2L and NaSCN, where L1 and L2 are respectively in 1 and 2, respectively. The inner N2O2 and outer O4 compartments are basically occupied by two distinct Cd metal ions resulting from the de-protonated version of the ligand's with the Cd metal ions adopting a capped octahedral configuration. Multiple non-covalent supramolecular interactions are delineated by Hirshfeld Surface and 2D fingerprint plot analysis of solid-state crystal crystals. In a new dimension of DFT, the sparse tetrel bonding reactions in the complex, involving the CH3 group, were evaluated.

A Comparison of Fundamental Methods for Iso-surface Extraction

Both mathematically generated data sets as well as real data sets are compared. On the other hand, the Hausdorff distance and root mean square are used to compare methods on real data sets.

A comprehensive rotational study of astronomical iso-pentane within 84 to 111 GHz

In a 3-mm atmospheric window between 84 to 111 GHz in the hot central area Sagittarius B2, the rotational line survey by ALMA recently revealed the presence of i-C3H7CN and n-C3H7CN. This was the first interstellar characterization of a linear straight chain molecule. We also report the rotational spectra of C5H12 isomeric group in the same frequency range in this light.

On Iso-octane Combustion with Ozone Addition under HCCI Engine-Like Conditions

Numerical experiments were conducted to investigate the effects of ozone on the Ignition Delay Time of iso-octane/air mixtures under typical operating conditions of HCCI engines. The model was used to investigate iso-octane/air/ozone mixtures under typical operating conditions of HCCI engines operating with lean mixtures. The results show that as ozone concentration rises, IDT decreases, with a greater effect at low temperatures, and the NTC effect decreases. However, the reduction of IDT with ozone addition is less as ozone concentration rises, particularly at low temperatures. An increased pressure, on the other hand, promotes faster ozone decomposition and increases the ozone reduction in all temperatures except for the range 760-840 K, where the opposite effect occurs due to NTC phenomena. Both ozone and pressure have no effect on the percentage decrease of IDT in 1200 K, although both ozone and pressure have no effect on the percentage reduction of IDT.

Data Centre Risk Analysis Using ISO 31000:2009 Framework

Almost all businesses depend on technology, one of which is the use of data centers, due to advancements in information technology in the world. The rise in the number of applications and communication information technology services at pharmaceutical companies has resulted in a greater chance of application from data centers that must pay close attention to the dangers of digital attacks to physical risks. The results of this study have resulted in the production of risk management papers relating to the risk management process and current risk mitigation techniques.

Microdosimetry-based quality factors for ISO reference photon and beta sources: TOPAS Monte Carlo study

According to ISO reference photon and beta sources, personnel dosimeters are calibrated in terms of operational quantities, such as H p and H p against ISO reference photon and beta sources, respectively. In the ICRU-4 element tissue phantom, H p and H p are defined at 1 cm and 0. 07 bcm depths. Qu0305, the FLUKA-based Linear Energy Transfer dependent Qu0305, and the 135-based Qu0305 are both estimated at these depths using the TOPAS-based microdosimetric standard from the previous study. As per ICRP Report 60, the study includes FLUKA-based Qu0305 results calculated using Q vs. L data calculated using Q vs. L relationships.

Design and development of quality management system based on ISO 16949

According to the actual situation of companies, this paper aims to plan and implement a quality management system based on ISO 16949. Enterprises can increase their productivity by improving product quality. A scope is presented in this paper to determine OEE of automatic cable machine and efficiency improvement are applied to practice, Define, Measure, Analyze, Increase, and Control. The results of the report show that AM has successfully reduced the defect rate of automatic cable machines from 1. 7 percent to 0. 2 percent.
