Palvelumuotoilu myymäläsuunnittelussa : case M-Boxi
No full textTässä opinnäytetyössä tarkastellaan palvelumuotoilun hyödyntämistä myymäläsuunnittelussa. Samalla vertaillaan
perinteistä myymäläsuunnittelua palvelumuotoilun keinoin suunniteltavaan myymälään. Tapaustutkimuksen
kohteena on laukkujen vähittäismyymälä M-Boxi.
Työssä selvitetään palvelumuotoilun hyödyntämistä myymälän toimivuudessa ja sitä, kuinka palvelumuotoilulla
voisi kehittää ja parantaa myymälän palvelukokemuksia. Tämä työ on teoreettinen tutkimus. Tutkimuksessa on
hyödynnetty alan kirjallisuutta sekä haastatteluja M-Boxin omistajille sekä pääsuunnittelija JRA Finland Oy:lle.
Haastatteluilla on kartoitettu myymälä- ja brändiuudistuksen taustaa M-Boxissa.
Palvelumuotoilun hyödyntäminen myymälätilan suunnittelussa kokonaisvaltaiseksi kokemukseksi ja elämykseksi
on hyödyllinen keino. Palvelumuotoilun avulla myymäläsuunnitteluun saadaan mukaan myös asiakasnäkökulma
ja asiakkaan tarpeet. Perinteisessä myymäläsuunnittelussa toteutetaan tilaajan toiveita ja keskitytään myymälän
visuaaliseen ilmeeseen. Asiakas- ja käyttäjäymmärrys on olleellisen tärkeää, jotta myymälä ja sen palvelut
olisivat yhtenäisiä ja tarjoaisivat tavoitteen mukaisia palvelukokemuksia niin asiakkaille kuin henkilökunnalle.
Kun palvelumuotoilun prosessit ja keinot otetaan mukaan myymäläsuunnitteluun, saadaan aikaan
myymäläympäristö, joka palvelee niin asiakasta kuin tilaajaakin. Palvelumuotoilulla voidaan parantaa asiakkaan
palvelukokemusta, kun kehitetään ostoprosessia ja tuotetaan uusia palveluideoita.This thesis deals with the service design in shop design. In general, author finds out which methods of service design
facilitate shopping experience for a customer. In addition, the traditional shop design is compared with the methods
of service design. Therefore, a shop called M-Boxi is used as an example to explain the theory.
Following this, author investigates how the service design is used in shop design. In addition, there is also found out
how shop services can be developed by service design methods. This research is mostly theoretical and it is based on
existing written material of service design and shop design. Further more, author used some interviews to explain the
background of renovation in M-Boxi.
Using service design methods in shop design is useful when creating holistic and emotional experiences for a
customer. In service design, it is necessary to take the behaviors and needs of the customers into account. In the
traditional shop design, the focus is on visual elements of the shop. More over in service design, the main issue is to
improve the customer's buying experience. In order to do this, service design methods are used to plan and guide the
behaviour of the customers. Understanding the client is crucial so the shop can offer uniform experiences which meet
the needs of customers.
When service design methods and traditional shop design are taken into account the result is a shop environment
which serves both the customer and the client. With the service design methods the shopping experience of the client
can be improved further by developing processes and new concepts
Multi-echelon inventory modeling and supply redesign
No full textThesis: M. Eng. in Supply Chain Management, Massachusetts Institute of Technology, Supply Chain Management Program, 2017.Cataloged from PDF version of thesis.Includes bibliographical references (pages 46-49).Many businesses struggle to optimize the flow of inventory and finished goods through existing plants and facilities. The integration of inventory costs, organizational processes, and changing business dynamics make it difficult to determine the optimal flow. This thesis examines the flow of raw materials and finished goods through the supply chain of a multi-national oilfield services company. We study a centralized inventory approach, assessed through heuristics, against the existing decentralized approach. Sensitivity analysis with regard to service level, and mode of transport strengthened the analysis. We show that demand aggregation and lead time are important factors in determining the upper echelon for a company's internal distribution model. Potential safety stock reduction is 2%, which is mainly due to the improved coordination for materials flowing to the final echelon in the supply chain. However, pipeline inventory increases by 12% as a result of longer lead times.by Patrick Scott and Boxi Xu.M. Eng. in Supply Chain Managemen
Comparison of high-power single-ring isolation and box isolation in elderly patients with persistent atrial fibrillation
No full textAbstract Background This study evaluated the superiority of single-ring isolation (SRI) over box isolation using high power in elderly patients with persistent atrial fibrillation (PeAF). Methods We retrospectively studied elderly patients with PeAF who underwent primary catheter ablation. The patients were divided into the SRI group and the posterior box isolation (BOXI) group. Basic characteristics, procedural variables, complications and atrial arrhythmia recurrence rates were collected. Results Forty-five pairs of patients in the two groups were matched by 1:1 PSM. Compared with that in the BOXI group, the total procedure time in the SRI group was not significantly different (P = 0.340). However, there were significant reductions in the total ablation time, ring ablation lesions and number of lesions on the posterior wall in patients who underwent SRI compared to those who underwent BOXI (all P 0.05). Conclusions High-power SRI is safe and feasible and may be superior to the BOXI for experience of elderly patients with PeAF
A linearised inverse conductivity problem for the Maxwell system at a high frequency
No full textPreprint version available. Also available from the publisher at DOI (may not be free).We consider a linearised inverse conductivity problem for electromagnetic waves in a three dimensional bounded
domain at a high time-harmonic frequency. Increasing stability bounds for the conductivity coefficient in the full Maxwell
system and in a simplified transverse electric mode are derived. These bounds contain a Lipschitz term with a factor growing
polynomially in terms of the frequency, a H¨older term, and a logarithmic term which decays with respect to the frequency
as a power. To validate this increasing stability numerically, we propose a reconstruction algorithm aiming at the recovery of
sufficiently many Fourier modes of the conductivity. A numerical evidence sheds light on the influence of the growing frequency
and confirms the improved resolution at higher frequencies.V. Isakov is supported in part by the Emylou Keith and Betty Dutcher Distinguished Professorship and

Linearized inverse Schrödinger potential problem at a large wavenumber
No full textClick on the DOI link to access the article (may not be free).We investigate recovery of the (Schrodinger) potential function from many boundary measurements at a large wavenumber. By considering such a linearized form, we obtain a Holder type stability which is a big improvement over a logarithmic stability in low wavenumbers. Furthermore we extend the discussion to the linearized inverse Schrodinger potential problem with attenuation, where an exponential dependence of the attenuation constant is traced in the stability estimate. Based on the linearized problem, a reconstruction algorithm is proposed aiming at the recovery of the Fourier modes of the potential function. By choosing the large wavenumber appropriately, we verify the efficiency of the proposed algorithm by several numerical examples.Emylou Keith and Betty Dutcher Distinguished Professorship and the NSF grant DMS 15-14886.

Analytical and numerical bounds on entanglement delivery waiting times
No full textThe vision of a global network that enables quantum communications between any point on Earth is known as the quantum internet. One crucial element of this network is the use of quantum repeater chains, which have the potential to overcome transmission losses and implement entanglement or quantum key distribution protocols over extended distances. There are various proposals for quantum repeaters, but they can generally be evaluated based on two main figures of merit: the average time for end-to-end entanglement delivery and the associated average fidelity. However, characterizing these quantities can be difficult due to factors such as feedback loops, decoherence, entanglement generation being a probabilistic process, and the potential failure of subprotocols. In this talk, I will discuss algorithmic and analytical methods for computing these quantities for relevant families of protocols.Quantum Computer Scienc
Increasing stability in the linearized inverse Schrödinger potential problem with power type nonlinearities
No full textWe consider increasing stability in the inverse Schrödinger potential problem with power type nonlinearities at a large wavenumber. Two linearization approaches, with respect to small boundary data and small potential function, are proposed and their performance on the inverse Schrödinger potential problem is investigated. It can be observed that higher order linearization for small boundary data can provide an increasing stability for an arbitrary power type nonlinearity term if the wavenumber is chosen large. Meanwhile, linearization with respect to the potential function leads to increasing stability for a quadratic nonlinearity term, which highlights the advantage of nonlinearity in solving the inverse Schrödinger potential problem. Noticing that both linearization approaches can be numerically approximated, we provide several reconstruction algorithms for the quadratic and general power type nonlinearity terms, where one of these algorithms is designed based on boundary measurements of multiple wavenumbers. Several numerical examples shed light on the efficiency of our proposed algorithms.peerReviewe
Increasing stability of the first order linearized inverse Schrödinger potential problem with integer power type nonlinearities
No full textWe investigate the increasing stability of the inverse Schrödinger potential problem with integer power type nonlinearities at a large wavenumber. By considering the first order linearized system with respect to the unknown potential function, a combination formula of the first order linearization is proposed, which provides a Lipschitz type stability for the recovery of the Fourier coefficients of the unknown potential function in low frequency mode. These stability results highlight the advantage of nonlinearity in solving this inverse potential problem by explicitly quantifying the dependence to the wavenumber and the nonlinearities index. A reconstruction algorithm for general power type nonlinearities is also provided. Several numerical examples illuminate the efficiency of our proposed algorithm.37 pages, 8 figure
On permutation symmetries of hopfield model neural network
No full textDiscrete Hopfield neural network (DHNN) is studied by performing permutation operations on the synaptic weight matrix. The storable patterns set stored with Hebbian learning algorithm in a network without losing memories is studied, and a condition
which makes sure all the patterns of the storable patterns set have a same basin size of attraction is proposed. Then, the permutation symmetries of the network are studied associating with the stored patterns set. A construction of the storable patterns set satisfying that condition is achieved by consideration of their invariance under a point group
