Revision of Lacquer Range
No full textDetta examensarbete utfördes på lack- och tryckavdelningen på företaget Emballator Ulricehamns Bleck med målet att undersöka om det fanns brister och slöserier i det befintliga lacksortimentet. Efter en noggrann nulägesanalys som inkluderade bland annat genomgång av applicerbara datablad, arbetsplatsintroduktion och studiebesök hos en av företagets lackleverantörer genomfördes arbetet utan missöden. Nulägesanalysen resulterade i en översikt av dagens lacksortiment och efter det fortsatte arbetet med att ta fram en egenskapsmatris innehållande samtliga lacker i sortimentet. Efter att de lacker som föll inom författarens specifikation för dubbletter identifierats togs ett antal rekommendationer för hur företaget bör agera för att ha ett uppdaterat sortiment fram. Förutom detta har författaren tagit fram ett förslag på hur företaget skall testa sina insideslacker för att i framtiden ha möjligheten att undersöka om några av dessa kan tas ut ur sortimentet.This degree project was performed in the coating and printing department at Emballator Ulricehamns Bleck. The task was to investigate if any waste and improvement opportunities in the lacquer range at Emballator Ulricehamns Bleck exist. A thorough analysis of the current situation including a review of applicable data, work place introduction and a visit to one of the company´s suppliers was made. This gave a good understanding of the current status. The result of the analysis was an overview of the lacquer range that helped the author to compile a characteristic matrix including all the products in the lacquer range. Following this the author identified products that could be specified as duplicates. Furthermore the degree project has resulted in 5 recommendations regarding future work with the design of the lacquer range. The last part of the project resulted in an analysis of today’s test schedule and a suggestion how to modify it for future needs
Sharp uniform-in-time propagation of chaos
No full textWe prove the optimal rate of quantitative propagation of chaos, uniformly in
time, for interacting diffusions. Our main examples are interactions governed
by convex potentials and models on the torus with small interactions. We show
that the distance between the -particle marginal of the -particle system
and its limiting product measure is , uniformly in time, with
distance measured either by relative entropy, squared quadratic Wasserstein
metric, or squared total variation. Our proof is based on an analysis of
relative entropy through the BBGKY hierarchy, adapting prior work of the first
author to the time-uniform case by means of log-Sobolev inequalities.Comment: 28 page
Understanding intraday credit in large-value payment systems
No full textThis article explains how large-value payment systems work, using either gross or net settlement. The author discusses risk control in a real-time gross settlement system and analyzes the pricing of credit to provide intraday liquidity. She argues for distinguishing between consumption/investment debt and payment debt. A theoretical model suggests that, under the assumption that there are no opportunities for intraday optimization of consumption and production, the risk-free rate on intraday payment credit should be zero. This is because the cost of intraday liquidity is a transaction cost of the underlying goods/assets trade and, thus, should be minimized.Payment systems ; Credit ; Debt ; Liquidity (Economics)
The lower and upper bounds of the Federal Open Market Committee's long-run inflation objective
No full textIt is widely acknowledged that the Fed can control the average inflation rate over a period of time reasonably well. Because of this and the Federal Open Market Committee's (FOMC's) long-standing commitment to price stability, the author argues that the FOMC has an implicit long-run inflation objective (LIO)-lower and upper bounds to the long-run inflation rate. He shows that the statements made by the FOMC in 2003 clarified the lower bound of its LIO and that the average of long-run inflation expectations responded by rising about 80 basis points. Moreover, consistent with reducing the market's uncertainty about the FOMC's LIO, long-run inflation expectations became more stable. The FOMC has recently been more specific about the upper bound of its LIO as well. The FOMC could eliminate the remaining uncertainty by establishing an explicit, numerical inflation objective.Federal Open Market Committee ; Inflation (Finance)
Towards a global fit to extract the B->Xs gamma decay rate and Vub
No full text© Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence. The total B → Xsγ decay rate and the CKM-matrix element |Vub| play an important role in finding indirect evidence for new physics affecting the flavor sector of the Standard Model, complementary to direct searches at the LHC and Tevatron. Their determination from inclusive B-meson decays requires the precise knowledge of the parton distribution function of the b quark in the B meson, called the shape function. We implement a new model-independent framework for the shape function with reliable uncertainties based on an expansion in a suitable set of basis functions. We present the current status of a global fit to BABAR and Belle data to extract the shape function and the B → Xsγ decay rate.United States.
