Kelluvien asuntojen infratarkastelu

Tämän insinöörityön tavoitteena on tuottaa ratkaisu kelluvien asuntojen sähkö-, vesi- ja viemäriverkostolle. Ratkaisussa otetaan huomioon sen toimivuus pohjoismaisissa olosuhteissa ympäri vuoden. Erityishuomiota vaativat vedenpinnan korkeuserot jotka voivat olla rasitteeksi vesi- ja viemäröintikanavalle ja liitoksille sekä rakenteiden jäätymisen tuomat haasteet eristyksille. Insinöörityössä selvitetään onko kohteessa mahdollista liittää asuntojen viemäröintikanava suoraan kunnallisverkkoon tai vaihtoehtoisesti rannalle sijoitettavaan omaan umpisäiliöön josta se tyhjennetään loka-autolla. Tutkimusmenetelmä on vertaileva case tutkimus ja tavoitteena on tuottaa mahdollisimman kustannustehokas ja toimiva suunnitelma yrityskäyttöön. Insinöörityössä keskitytään yhteen ratkaisuun joka ei välttämättä sellaisenaan sovellu käytettäväksi muihin vastaaviin asumismuotoihin

A systems engineering hackathon – a methodology involving multiple stakeholders to progress conceptual design of a complex engineered product

This paper describes a novel hackathon-style system engineering process and its value as an agile approach to the rapid generation and development of early design concepts of complex engineered products–in this case a future aircraft. Complex product design typically requires a diverse range of stakeholders to arrive at a consensus of key decision criteria and design factors, which requires effective articulation and communication of information across traditional engineering and operational disciplines. The application of the methodology is highlighted by means of a case study inspired by Airbus where stakeholder involvement and internal collaboration among team members were essential to achieve a set of agreed goals. This paper shows that a hackathon grounded on systems engineering approaches and structured around the technical functions within an engineering company has the capability and capacity to communicate a coherent vision and rationale for the conceptual design of a complex engineered product. The hackathon method offers significant benefits to these stakeholders to better manage, prioritize, and decrease excessive complexities in the overall design process. A significant benefit of this agile process is that it can achieve useful results in a very short timeframe (i.e., 80% reduction), where it could take up to a year to accomplish compared with using current/regular internal methods.N/

Game design principles influencing stroke survivor engagement for VR-Based upper limb rehabilitation

Engagement with one's rehabilitation is crucial for stroke survivors. Serious games utilising desktop Virtual Reality could be used in rehabilitation to increase stroke survivors' engagement. This paper discusses the results of a user experience case study that was conducted with six stroke survivors to determine which game design principles are or would be important for engaging them with a desktop VR serious games designed for the upper limb rehabilitation. The results of our study showed the game design principles that warrant further investigation are awareness, feedback, interactivity, flow and challenge; and also important to a great extent are attention, involvement, motivation, effort, clear instructions, usability, interest, psychological absorption, purpose and a first-person view

What's scene and not seen: Influences of movement and task upon what we see

Studies concerning the processing of natural scenes using eye movement equipment have revealed that observers retain surprisingly little information from one fixation to the next. Other studies, in which fixation remained constant while elements within the scene were changed, have shown that, even without refixation, objects within a scene are surprisingly poorly represented. Although this effect has been studied in some detail in static scenes, there has been relatively little work on scenes as we would normally experience them, namely dynamic and ever changing. This paper describes a comparable form of change blindness in dynamic scenes, in which detection is performed in the presence of simulated observer motion. The study also describes how change blindness is affected by the manner in which the observer interacts with the environment, by comparing detection performance of an observer as the passenger or driver of a car. The experiments show that observer motion reduces the detection of orientation and location changes, and that the task of driving causes a concentration of object analysis on or near the line of motion, relative to passive viewing of the same scene
