    Get PDF
    Recently, advancements in technology improve product safety considerations globally. High-tech equipment and tools become more accessible for organizations to manage manufacturing effectively and safely. In this way, they focus on producing safer products that are qualified for public consumption. With the introduction of clean energy technologies on roads, product safety discussions about electric vehicles increased simultaneously. Especially for globally operating battery manufacturers, demonstrating their compliance with international regulations, standardizations, and customer requirements poses difficulties. Unreliable and inadequate compliance management processes may obstruct operations and decrease competition capability in the global market. Throughout this thesis, safety-related requirements compliance inside an EV battery manufacturer company is investigated in accordance with a combined compliance management model. This model comprises the following steps: identifying and discovering the requirements, interpreting the requirements, identifying possible changes required in products or operations, identifying and evaluating compliance risks, compliance decisions specifying a method of compliance, communication, implementation, and evaluation and monitoring. In this thesis, safety-related requirements cover regulations, legislations, standards, and customer-specific requirements. A qualitative research approach with a descriptive case study is adopted in the thesis in order to provide in-depth outcomes related to the research topic. The findings from investigation of literature and semi-structured interviews are utilized in the process of discovering the company’s current status and encountered problems in management of compliance with product safety requirements. With the help of the findings and examination of the best practices regarding compliance management processes, improvement opportunities for the EV battery manufacturer company are recommended. The findings of the thesis show although the current applications of the case company in management of compliance with product safety requirements are not in poor quality, there still exist some parts to improve their insufficiencies and missing sides. Need for more skilled people for interpreting and comparing the requirements with the company’s operations, confronting language differences in discovering global requirements, not having an efficient communication process, and unclear responsibilities are some of the findings of the research as improvement needs. This thesis proposes possible enhancement activities for the company by exploring literature, and previously conducted research related to best practices for management of compliance with product safety requirements. Different solutions are listed as following: management system adoption, efficient documentation, regular compliance checks, global design file, benchmarking, external support, requirements follow-up by product safety people, platform to reach all customers, international networking, product safety and compliance plan, attending to standards drafting processes, comparison between different market standards, global product committee, defining common minimum requirements, and continuous training for people involved in product safety. Overall, this study contributes to the company and academics in the context of managing compliance of product safety requirements for globally operating manufacturers by investigating previous studies, regulations, standards and an EV battery manufacturer company

    An Approach for Economic Analysis of Intermodal Transportation

    Get PDF
    A different intermodal transportation model based on cost analysis considering technical, economical, and operational parameters is presented. The model consists of such intermodal modes as sea-road, sea-railway, road-railway, and multimode of sea-road-railway. A case study of cargo transportation has been carried out by using the suggested model. Then, the single road transportation mode has been compared to intermodal modes in terms of transportation costs. This comparison takes into account the external costs of intermodal transportation. The research reveals that, in the short distance transportation, single transportation modes always tend to be advantageous. As the transportation distance gets longer, intermodal transportation advantages begin to be effective on the costs. In addition, the proposed method in this study leads to determining the fleet size and capacity for transportation and the appropriate transportation mode

    The nuclear level densities and γ\gamma-ray strength functions of 138,139,140^{138,139,140}La were measured using the 139^{139}La(3^{3}He, α\alpha), 139^{139}La(3^{3}He, 3^{3}He^\prime) and 139^{139}La(d, p) reactions. The particle-γ\gamma coincidences were recorded with the silicon particle telescope (SiRi) and NaI(Tl) (CACTUS) arrays. In the context of these experimental results, the low-energy enhancement in the A\sim140 region is discussed. The 137,138,139^{137,138,139}La(n,γ)n, \gamma) cross sections were calculated at ss- and pp-process temperatures using the experimentally measured nuclear level densities and γ\gamma-ray strength functions. Good agreement is found between 139^{139}La(n,γ)n, \gamma) calculated cross sections and previous measurements

    COVIDiSTRESS Global Survey dataset on psychological and behavioural consequences of the COVID-19 outbreak

    This N = 173,426 social science dataset was collected through the collaborative COVIDiSTRESS Global Survey - an open science effort to improve understanding of the human experiences of the 2020 COVID-19 pandemic between 30th March and 30th May, 2020. The dataset allows a cross-cultural study of psychological and behavioural responses to the Coronavirus pandemic and associated government measures like cancellation of public functions and stay at home orders implemented in many countries. The dataset contains demographic background variables as well as measures of Asian Disease Problem, perceived stress (PSS-10), availability of social provisions (SPS-10), trust in various authorities, trust in governmental measures to contain the virus (OECD trust), personality traits (BFF-15), information behaviours, agreement with the level of government intervention, and compliance with preventive measures, along with a rich pool of exploratory variables and written experiences. A global consortium from 39 countries and regions worked together to build and translate a survey with variables of shared interests, and recruited participants in 47 languages and dialects. Raw plus cleaned data and dynamic visualizations are available.Measurement(s) psychological measurement center dot anxiety-related behavior trait center dot Stress center dot response to center dot Isolation center dot loneliness measurement center dot Emotional Distress Technology Type(s) Survey Factor Type(s) geographic location center dot language center dot age of participant center dot responses to the Coronavirus pandemic Sample Characteristic - Organism Homo sapiens Sample Characteristic - Location global Machine-accessible metadata file describing the reported data:Peer reviewe

    Stress and worry in the 2020 coronavirus pandemic: Relationships to trust and compliance with preventive measures across 48 countries in the COVIDiSTRESS global survey

    Get PDF
    The COVIDiSTRESS global survey collects data on early human responses to the 2020 COVID-19 pandemic from 173 429 respondents in 48 countries. The open science study was co-designed by an international consortium of researchers to investigate how psychological responses differ across countries and cultures, and how this has impacted behaviour, coping and trust in government efforts to slow the spread of the virus. Starting in March 2020, COVIDiSTRESS leveraged the convenience of unpaid online recruitment to generate public data. The objective of the present analysis is to understand relationships between psychological responses in the early months of global coronavirus restrictions and help understand how different government measures succeed or fail in changing public behaviour. There were variations between and within countries. Although Western Europeans registered as more concerned over COVID-19, more stressed, and having slightly more trust in the governments' efforts, there was no clear geographical pattern in compliance with behavioural measures. Detailed plots illustrating between-countries differences are provided. Using both traditional and Bayesian analyses, we found that individuals who worried about getting sick worked harder to protect themselves and others. However, concern about the coronavirus itself did not account for all of the variances in experienced stress during the early months of COVID-19 restrictions. More alarmingly, such stress was associated with less compliance. Further, those most concerned over the coronavirus trusted in government measures primarily where policies were strict. While concern over a disease is a source of mental distress, other factors including strictness of protective measures, social support and personal lockdown conditions must also be taken into consideration to fully appreciate the psychological impact of COVID-19 and to understand why some people fail to follow behavioural guidelines intended to protect themselves and others from infection. The Stage 1 manuscript associated with this submission received in-principle acceptance (IPA) on 18 May 2020. Following IPA, the accepted Stage 1 version of the manuscript was preregistered on the Open Science Framework at https://osf.io/g2t3b. This preregistration was performed prior to data analysis

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
