Opis:: This paper describes a Design Workshop course offered at the Electrical and Computer Engineering Department (ECE) at the University of Minnesota Duluth (UMD). The workshop course is one mechanism by which students completing the ECE program at UMD can satisfy the requirement for a senior design project. The design workshop topic for the fall 2010 was the use of fuzzy logic to control comfort in solar home. The workshop is described. The project work is evaluated during the process as well as the final results using principle based on Problem Based and Project Organized Learning (PBL). The results show that the students learning outcome has been very high.
W artykule opisano kurs projektowania oferowany w formie warsztatów na Wydziale Inżynierii Elektrycznej i Komputerowej Uniwersytetu Minnesota Duluth. Warsztaty są jednym ze sposobów, w jaki studenci ostatniego roku mogą wywiązać się z przygotowania wymaganego od nich projektu. Tematyką kursu projektowania w semestrze zimowym roku akademickiego 2010/2011 było zastosowanie logiki rozmytej do kontrolowania domu korzystającego z energii słonecznej. Przy bieżącej ocenie projektów studentów oraz przy wystawianiu ocen końcowych zastosowano zasady oparte na problemowo-projektowej metodzie nauczania. Otrzymane rezultaty wykazały wysokie efekty kształcenia.

Tytuł:: The Effect of Reclaim Primary Quality on Moulding Sand Parameters and Quality of Ductile Iron Casting Surface Layer

Opis:: The aim of the research was to determine the effect of the primary quality of reclaim from dry mechanical reclamation on the strength properties and service life of moulding sands based on this reclaim. Another aim was to establish the effect of the quality of reclaim, sulphur content - in particular, on the surface quality and thickness of the deformed surface layer in ductile iron castings. The research has revealed differences in the strength parameters and service life (mouldability) of sands based on the tested reclaims, depending on the type of the furfuryl resin used, including resins whose synthesis was done as part of the Żywfur project. Examinations of the structure of the surface layer of test castings poured in moulds made of loose self-hardening sands containing the addition of reclaim have confirmed the occurrence of degenerated spheroidal graphite in this part of the casting. It should be noted here that when massive castings with a long solidification time are made, the graphite degeneration effect can be more visible and the layer with the changed structure can increase in thickness. The research has clearly shown that it is necessary to control the parameters of the reclaim, including sulphur content which is transferred from the hardener and accumulates on the grains. This phenomenon has a negative impact not only on the sand strength and technological properties but also on the surface layer of castings.

Opis:: The article takes into consideration the researches concerning inserting the Glassex additive to the microwaved-hardened and self-hardened moulding sands with water glass. In the research different types of ester hardeners to self-hardened moulding sands with water glass were used. The influence of Glassex additive on retained strength of moulding sands with different hardeners and prepared by different technologies of hardening were tested. The influence of different hardeners and the technology of hardening on retained strength of moulding sand with water glass and the Glassex additive were also estimated.

Opis:: The unique nature of the Starunia palaeontological site, where near-perfectly preserved large mammals were discovered at the beginning of the 20th century, and incomplete knowledge on the development of palaeoenvironment in the Velyky Lukavets River valley in the Late Pleistocene and Holocene were the reasons for undertaking new comprehensive palaeobotanical and malacological studies. Starunia is also one of the sites bearing Pleistocene fossil flora, rare in this part of Europe. The results of plant macrofossil analysis show that in the Weichselian Middle Pleniglacial the landscape was dominated by steppe and tundra plant communities, being represented mostly by various grass and sedge species. Areas of higher humidity were covered with shrub tundra with Betula nana. The temperature requirements of taxa which are cool climate indicators show that the minimum July temperature amounted to at least 10°C. The record of Late Weichselian malacofauna confirms the dominance of an open landscape, mostly with steppe and steppe-tundra communities, as well as the presence of a dry, continental climate. At the beginning of the Holocene, an improvement of climatic and humidity conditions led to a fast local expansion of plant communities of the low and transition peat bog type, in the surroundings of shallow, periodically drying-up water pools. From the Middle Pleniglacial up to the present day, the area has been characterized by the presence of species tolerating an increased amount of salt in the environment. Their presence should be associated with natural brine effluences derived from Miocene strata in the bedrock.
