Data sorvin ääreen:TILT-projektin loppuraportti

Teollinen internet liiketoiminnan tukena (TILT) -projekti on tiukasti sidoksissa aikamme keskeiseen megatrendiin. Uusiutuva Internet, tekoäly ja sen mahdollistamat uudet teknologiat ovat tehneet projektin tutkimusalueesta vielä keskeisemmän kuin ehkä osattiin ajatella projektihakemusta kirjoitettaessa. Nämä teemat ovat nousseet nyt kaikkien huulille, ja edelläkävijyys niissä on nostettu kansankunnan keskeiseksi menestysreseptiksi eurooppalaisella tasolla. Tässä projektiraportissa rajataan aluksi TILT-projektin tutkimusalue lyhyesti, jonka jälkeen esitellään projektissa saavutettuja tuloksia. Loppuosa raportissa keskittyy pohdintaan tulosten vaikuttavuudesta ja jatkokehitystarpeista. TILT-projekti toteutettiin vuosina 2015-2018. Tutkimusosapuolina hankkeessa olivat Oulun yliopiston alainen Kerttu Saalasti -instituutti (KSI) sekä Centria tutkimus ja kehitys,joka myös toimi hankkeen koordinaattorina. Painopisteeksi muodostuivat toisaalta sensoriratkaisut sekä tiedonsiirron teknologia ja turvallisuus, toisaalta datan käsittely ja tietoon liittyvät turvallisuusriskit. Näiden kautta pyrittiin tuottamaan tietoa, miten yritykset pystyvät hyödyntämään teollista internetiä toiminnassaan sekä luoda edellytykset uusille liiketoimintaprosesseille ja mahdollisuuksille.

Optimal operation of a district heating power plant with thermal energy storage

This paper presents an optimal control strategy for a district heating power plant with thermal energy storage. The main goal of the control strategy is to reduce the operation costs of the power plant, by scheduling the boilers, the operation of the thermal energy storage and the curtailment on the loads. The problem is stated as a constrained optimization in the form of a Mixed Integer Linear Program (MILP), embedded on an Model Predictive Control (MPC) framework. Particular attention is paid to modeling of boiler

Model Predictive Control for Optimization of Combined Heat and Electric Power Microgrid

This is a contribution to the economic dispatch problem of combined electrical and heat power microgrids. A mixed integer linear microgrid model has been developed; the microgrid operations optimization problem has been formulated using Mixed-Integer Linear Programming and Model Predictive Control technique has been applied to take system uncertainties into account. The proposed optimization algorithm has been applied to a tertiary site microgrid, located in Finland; the obtained numerical results have been compared with a heuristic algorithm

Accelerating full-thickness skin wound healing using Zinc and Cobalt doped-bioactive glass-coated eggshell membrane

The quest to develop advanced wound dressing with excellent healing properties is an unending clinical chal-lenge. Several biological molecules have shown promising results in this regard. We utilized eggshell membrane, a waste product generated from egg processing industries, and coated it with bioactive glass/ion-doped (Zn, Co) bioactive glass in the nanoscale range to develop four different types of wound dressing mats (ESM/BAG, ESM/ ZnBAG, ESM/CoBAG, ESM/ZnCoBAG). All the mats were cytocompatible with human dermal fibroblasts and maintained cytoskeletal and nuclear morphology up to day 14 of culture. On application of these mats over the full-thickness skin wounds in the rabbit model, enhanced wound closure was observed especially with the eggshell membrane/ion-doped bioactive glass mats. These mats also demonstrated orderly and timely deposition of ECM components i.e., collagen, elastin, and reticulin. These wound remodeling and early healing features could be attributed to the bioactive properties of eggshell membranes along with the Zinc and Cobalt doped bioactive glass. These mats thus hold enormous potential as an economic wound dressing and also in biomedical applications
