An integrated matlab code for homogenization-based topology optimization and generating functionally graded surface lattices for additive manufacturing
No full textTriply periodic minimal surfaces (TPMS) lattices are gaining popularity for enhancing structural efficiency in many engineering applications. Functionally graded TPMS structures provide more customized mechanical properties and improved functionality compared to typical homogenous designs by deliberately altering material properties throughout the lattice. This study presents a novel framework by integrating a homogenization-based topology optimization method with functionally graded lattice creation, utilizing a streamlined and versatile MATLAB code. The methodology encompasses several essential phases, including preprocessing, finite element analysis, sensitivity analysis, density filtering, optimization, element density visualization, and lattice reconstruction. These steps facilitate the development of highly efficient lattice structures with varied attributes, rendering them optimal for additive manufacturing and full-scale analysis. To ensure the accuracy of the established methodology, three optimization case studies with different boundary conditions are defined, and the mechanical reactions of the optimized lattice structures in filled with different TPMS structures are extensively validated by comparing them to both full-scale finite element models and experiments. The comparative results demonstrate that the mechanical responses obtained from topological analysis closely correspond to those acquired from full-scale models and experiments.TÜBİTAKPublisher versio

Opinnäytetyön nimi: Pienyrityksen ja tilitoimiston yhteistyö palkanlaskennassa
Työn ohjaaja: Merja Luukkonen
Työn valmistumislukukausi- ja vuosi: Syksy 2014 Sivumäärä: 36 + 3 liitesivua
Opinnäytetyön tavoitteena oli tutkia pienyrityksen ja tilitoimiston yhteistyötä ja työnjakomahdollisuuksia yrityksen palkanlaskentaprosessissa. Tarkoituksena oli selvittää minkälaisia palkanlaskentaan kuuluvia tehtäviä yrittäjä, joka haluaa hoitaa työntekijöidensä palkanlaskennan, voisi tarvittaessa siirtää tilitoimistonsa hoidettavaksi. Työnjakoa ja sen vaikutuksia käsitellään myös vastuunjakautumisen näkökulmasta. Opinnäytetyön toimeksiantajana on tilitoimisto RL-Tili Oy ja kohdeyrityksenä oululainen ravintola-alan yritys, joka käyttää toimeksiantajan tilitoimistopalveluja.
Teoreettinen viitekehys koostuu osapuolten väliseen toimeksiantosopimukseen liitetyistä palveluista ja sopimusehdoista. Lisäksi teoriassa käydään läpi palkkahallinnon prosesseja aina yksittäisen palkan laskemisesta palkanlaskijan tehtäviin koko työsuhteen aikana. Tutkimusmenetel-mänä on käytetty prosessianalyysiä kohdeyrityksen palkanlaskentaprosessin nykytilan kuvaamiseen. Lisäksi on käytetty teemahaastattelua tilitoimistoyritysten kokemusten ja mielipiteiden keräämiseen palkanlaskentaprosessin tehtävien työnjaosta.
Tutkimus osoitti, että tilitoimistoyritykset koosta riippumatta ovat hyvin myönteisiä kaikenlaiselle yhteistyölle asiakkaidensa kanssa. Sopimusvaiheessa jo huomioidaan asiakkaan tarpeet ja toi-veet ja yksilöityjä palvelupaketteja käytetään paljon. Sellaisissa tilitoimistoissa, joissa käytettiin nettipohjaista kirjanpito- ja palkanlaskentaohjelmistoa yhteistyö asiakkaiden kanssa sujui joustavimmin.
Tulosten perusteella tulin siihen johtopäätökseen, että kaikenlaista yhteistyötä palkanlaskennassa kohdeyrityksen ja toimeksiantajan välillä voidaan lisätä, mikäli käytössä on palkanlaskentaohjelmisto, jota molemmat osapuolet pääsevät käyttämään. Suosittelemani ohjelmisto on Palkka.fi-sivusto, joka kohdeyrityksellä on jo käytössä. Ohjelma on käyttäjilleen ilmainen ja siihen saa tarvittaessa tunnukset myös tilitoimistolle. Lisäksi kohdeyrityksen henkilöstömäärä on vuositasolla alle viisi, mikä myös puoltaa Palkka.fi-ohjelmiston soveltuvuutta tässä tapauksessa.

Title of thesis: Cooperation in payroll computation between small company and accounting firm
Supervisor: Merja Luukkonen
Term and year when the thesis was submitted: Autumn 2014 Number of pages: 36 + 3 pages of appendices
The aim of this thesis was to examine the cooperation and the possibilities of sharing duties in payroll computation between a small company and an accounting firm. The aim was to find out what kind of individual tasks in salary calculation an entrepreneur taking care of employees' payroll could transfer to the accounting firm. The division of tasks and its effects were examined also from the perspective of the division of responsibility. The thesis was commissioned by the accounting firm RL-tili Oy and the case company operates in catering business and is located in Oulu.
The theoretical framework consisted a commission agreement between the parties connected to the services and the terms of the contract. Furthermore, the theory discussed payroll administration processes for example an individual salary calculation and wages clerk duties throughout the course of employment. As a research method process analysis was employed to describe the case company's current state of the payroll process. In addition, the theme interview was also conducted to gather experiences and opinions of accounting firms in the division of tasks in the payroll process.
The study showed that accounting firms, regardless of size, welcome all kinds of cooperation with their customers. The agreement phase already takes customer's hopes and needs into account. Personalized service packages are widely used. Those accounting firms, using a web-based accounting and payroll software cooperation with the customers were the most flexible ones.
Based on the result it could be concluded that any kind of cooperation in payroll can be increased between the case company and RL-Tili Oy if there is a common payroll software. The recom-mended software is called Palkka.fi site, which is already being used by the case company. The programme is free and it is possible to add new users and create IDs to the accounting firm. The fact that the amount of employees' of the case company is less than five on an annual basis, supports the use of Palkka.fi software in this case.

A finite element based homogenization code in python: HomPy
No full textThe ability to predict the effective material property of composites with periodic micro-structures based on homogenization theory has been an effective method to analyze structures with complex heterogeneities. Homogenization codes have been made available for educational purposes including the homogenization code for the prediction of effective elasticity and thermal material properties in MATLAB. The aim of this educational paper is to present a Python version of the existing homogenization code and provide detailed diagrams of its key modules extending its ability to conduct analysis and design studies possibly via integration into commercial FEM software. Python has become a popular programming language due to its wide applicability to several disciplines, its portability, its flexibility by means of programming paradigms, its open-source nature, its well-documented libraries, and its easy-to-learn syntax. To increase the applicability and community reach of the homogenization algorithm presented, we provide a Python translation of the well-known MATLAB implementation. By doing so, we aim to increase the integration potential and adaptability of the homogenization approach to other computing packages and target adoption by a wider audience by leveraging the advantages of basing the solution on a free and open-source platform
Recurrence relations, associated formulas, and combinatorial sums for some parametrically generalized polynomials arising from an analysis of the Laplace transform and generating functions
No full textThe aim of this paper is to obtain some interesting infinite series representations for the Apostol-type parametrically generalized polynomials with the aid of the Laplace transform and generating functions. In particular, by using the method of generating functions, we derive not only recurrence relations, but also several other formulas, identities, and relations as well as combinatorial sums for these parametrically generalized numbers and polynomials and for other known special numbers and polynomials. These identities, relations and combinatorial sums are related to the two-parameter types of the Apostol-Bernoulli polynomials of higher order, the two-parameter types of Apostol-Euler polynomials of higher order, the two-parameter types of Apostol-Genocchi polynomials of higher order, the Apostol-Bernoulli polynomials of higher order, the Apostol-Euler polynomials of higher order, the Apostol-Genocchi polynomials of higher order, the cosine- and sine-Bernoulli polynomials, the cosine- and sine-Euler polynomials, the lambda-array-type polynomials, the lambda-Stirling numbers, the polynomials C-n(x,y)Cn(x,y), and the polynomials S-n(x,y)Sn(x,y). Finally, we present several new recurrence relations for these special polynomials and numbers.Scientific Research Project Administration of the University of AkdenizThe author Y.
