Työvuorosuunnittelu myynnin kehittämisen työvälineenä McDonald´s-ketjussa
Tämä opinnäytetyö on McDonald´s Oy:n tilaama tutkimuksellinen kehittämistyö. Kehittämistyössä tutkittiin McDonald´s-ketjun esimiesten työvuorosuunnittelun osaamistasoa sekä työvuorosuunnittelun vaikutusta myynnin kasvattamiseen. Kehittämishankkeen tavoitteena oli luoda kehitysehdotuksia, joilla saadaan kasvatettua yksikkökohtaista myyntiä työvuorosuun-nittelun avulla.
Aihetta on lähestytty tapaustutkimuksen keinoin. Opinnäytetyö koostuu tietoperustasta, ravintolapäälliköille tehdystä kyselytutkimuksesta ja kolmesta teemahaastattelusta. Tietoperustassa käsitellään henkilöstökulujen merkitystä ravintola-alalla sekä alan työvuorosuunnittelua. Tutkimusmenetelminä on käytetty puolistrukturoituja teemahaastatteluja sekä kyselytutkimusta.
Tutkimuksen tulosten perusteella on tehty kehitysehdotuksia McDonald´s-ketjulle työvuorosuunnittelun prosessiin. Kyselytutkimuksen ja teemahaastatteluiden tulokset, sekä yritykselle tehdyt kehitysehdotukset on jätetty julkaistusta versiosta pois, koska ne kuuluvat yrityksen liikesalaisuuden piiriin
COCrIP: Compliant OmniCrawler In-pipeline Robot
This paper presents a modular in-pipeline climbing robot with a novel
compliant foldable OmniCrawler mechanism. The circular cross-section of the
OmniCrawler module enables a holonomic motion to facilitate the alignment of
the robot in the direction of bends. Additionally, the crawler mechanism
provides a fair amount of traction, even on slippery surfaces. These advantages
of crawler modules have been further supplemented by incorporating active
compliance in the module itself which helps to negotiate sharp bends in small
diameter pipes. The robot has a series of 3 such compliant foldable modules
interconnected by the links via passive joints. For the desirable pipe diameter
and curvature of the bends, the spring stiffness value for each passive joint
is determined by formulating a constrained optimization problem using the
quasi-static model of the robot. Moreover, a minimum friction coefficient value
between the module-pipe surface which can be vertically climbed by the robot
without slipping is estimated. The numerical simulation results have further
been validated by experiments on real robot prototype

Design and optimal springs stiffness estimation of a Modular OmniCrawler in-pipe climbing Robot
This paper discusses the design of a novel compliant in-pipe climbing modular
robot for small diameter pipes. The robot consists of a kinematic chain of 3
OmniCrawler modules with a link connected in between 2 adjacent modules via
compliant joints. While the tank-like crawler mechanism provides good traction
on low friction surfaces, its circular cross-section makes it holonomic. The
holonomic motion assists it to re-align in a direction to avoid obstacles
during motion as well as overcome turns with a minimal energy posture.
Additionally, the modularity enables it to negotiate T-junction without motion
singularity. The compliance is realized using 4 torsion springs incorporated in
joints joining 3 modules with 2 links. For a desirable pipe diameter (\text{\O}
75mm), the springs' stiffness values are obtained by formulating a constraint
optimization problem which has been simulated in ADAMS MSC and further
validated on a real robot prototype. In order to negotiate smooth vertical
bends and friction coefficient variations in pipes, the design was later
modified by replacing springs with series elastic actuators (SEA) at 2 of the 4
joints.Comment: arXiv admin note: text overlap with arXiv:1704.0681
Architectural Education 2012 : Prospects and Keepings
The crucial challenges of the architecture and planning designs today: the climatic changes,
the fast growing urbanisation of the environments, the financial crisis, the impact of design by
computer, the need of knowledge basic designs etc, all these challenges can be the starting
point for an architectural education renewal.
Our proposal can be, then, optimistic, in the middle of a very complex and difficult scenario.
Sometimes, the worst scenarios can be the seed for radical innovation, and we will try to describe
this possibility of positive changes in architectural education, if, and only if, some conditions
are accomplished. The work has three parts: first, a pedagogic meditation taking into
account the last ideas about how our body and our mind behave in order to know challenges
of a general architectural education to day. The second part, it is the consideration of design
as a responsive «creative chronotope», using the definitions of the late Russian thinker Mikhail
Bakhtin, in order to take advantage of our professional circumstances today. And, finally, the
third part, will deal with the institutional aspect of architectural education and with the need
for new «scenarios» for more effective schools of architecture in our universities.Peer Reviewe
