Measurement systems

In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

Ultra-wideband (UWB) radars are getting much attention for maritime applications of smart and luxury ships in which UWB radar could be integrated into Bridge Navigational Watch & Alarm System - BNWAS. One of the interesting applications of UWB radar is vital signs measurement, which is a contactless method. UWB radar measures respiration and heartbeat rate by the motion of thorax for detecting and checking the state of people on the bridge.

Acne vulgaris is an inflammatory disease of the pilosebaceous unit, consisting of comedones, papules, pustules, nodules, and cysts. With the complexity of polymorphic nature, acne vulgaris is inherently difficult to assess and the measurement and grading of this condition is a recognized challenge for clinicians. This article presents a comprehensive preview of acne severity assessment according to timelines to give an overview of methods used to measure acne severity.

Introduction to shock & vibration gives an introduction to vibration through a description of the most common mechanical parameters leading to the behaviour of simple mass spring systems. Furthermore the different types of signals and their description is treated and the conversion between the different parameters is described mathematically and graphically. Finally the measurement units are defined.

The system of relations between the consumer and the seller has many factors that shape the dynamics of the market of goods and services based on the supply chain strategy. Supply chains satisfy customers by striving for delivering the right products to the right place at the right time, at the right quality and at the right quantity within an increasingly faster pace and lower cost. Theories of social entropy consider the system of social relations from the standpoint of the equilibrium of systems and their disproportion.

The article discloses methodological approaches to quantifying the level of penetration of block chain technologies into the regional socioeconomic environment in comparison to the supply chain strategies. Based on the methods of mathematical and statistical analysis, it allows you to formalize and convert a large array of data of a qualitative order into a single scale for measuring the process under study - the level of demand in the regional socio-economic environment for block chain technology.

This research focuses on two key research questions: how to measure spatial accessibility to green space in urban areas at fine resolution; and what is the status of spatial inequity in accessibility to green space in the MMA. Guided by the two research questions and based on a systematic review of literature on accessibility in general accessibility to green space in particular, a methodology has been developed for producing results needed to answer the research questions.

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.
