Remote administration and user experience evaluation of the iLab Heat Transfer Project site

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2006.Includes bibliographical references.The iLab Heat Transfer Project provides a means for students to remotely execute, via a web interface, experiments related to the topic of heat transfer. The website associated with this project provides instructors with the ability to remotely manage the performance of experiments by their students. This thesis describes improvements made to this website that are intended to grant more control to instructors. Specifically, the website has been augmented to provide remote instructors with complete control over experiment scheduling, user registration, document uploading, and other relevant administrative tasks. The interfaces by which users perform experiments have been modified to incorporate an audio and video feed of the laboratory equipment used in these experiments. In addition, the website has been extended with a feature that facilitates the viewing and analysis of questionnaire responses collected from students. The questionnaire responses provided by students have been examined to gain more knowledge about the effectiveness of various aspects of the website and experiment interfaces.by Rodney K.

Encouraging SMEs to participate in the management of common pool resources

In this paper we contribute to an understanding of how small and medium sized enterprises (SMEs) can be encouraged to participate in the management of environmental common pool resources. We do this by applying ideas from general theories about collective actions and, using evidence from interviews of people with experience dealing with SMEs, show how the ideas are relevant to SMEs. In line with previous research, we present evidence that communication is also necessary to help ensure SME participation. We conclude noting some evidence that suggests that local networks may contribute to successful management of global common pool resources.<br /

Religious morality - work and wealth: The relevance of religiously based moral principles to commercial activities in Australia

The corporate collapses that have occurred in Australia and elsewhere in recent years are of major importance not only to investors and creditors, but to all of those who are interested in and concerned with the conduct of commercial activities. It was inevitable that attention would focus on causes, questions being asked as to the conduct and behaviour of those responsible for the control of the corporate activities. It is to the latter that the discussion yet to follow in this thesis is directed. It is maintained that if the relevant executives had been guided by and had applied ethical conduct religiously based, that is, religiously derived norms of behaviour, in their commercial decision-making process that the errors of judgement that led, at least in part, to the financial failures might not have occurred. The discussion raises issues of morality, of business morality, and the extent to which recognition of the relevance of the tenets of religious morality can play a part in influencing good corporate governance. The question is asked, can a company's Code of Conduct be structured in such a way that it provides assistance to the executive, management personnel and other employees on moral issues at a time when they are called upon to make difficult ethical decisions? Moral and ethical considerations can be identified, but unless the individual has confidence in their relevance to a particular situation, they may well be put aside or disregarded when a decision is being made. A process needs to be found for incorporating in them material which becomes part and parcel of a corporate ethos or mentality, something that is a point of reference for good governance. If there is to be an expressed morality which impinges on commercial behaviour, it should be a morality of belief and of persuasion. It should be sufficient to motivate an individual in the conduct of the affairs over which that person has control or influence, to pass it on and communicate it to others in a convincing way. For this is the lesson of history. The ideas of a vocation and the infinite worth of each and every person, have seeped into and been absorbed by 'Western' consciousness. The source of the beliefs, deeply held and demonstrated, is Judaism and Christianity. The thesis seeks to obtain insight into the concept of morality and ethical standards in order to ascertain how best they can be aligned with economic activity

CO\u3csub\u3e2\u3c/sub\u3e Recycling Using Microalgae for the Production of Fuels

CO2 capture and recycle using microalgae was demonstrated at a coal-fired power plant (Duke Energy’s East Bend Station, Kentucky). Using an in-house designed closed loop, vertical tube photobioreactor, Scenedesmus acutus was cultured using flue gas as the CO2 source. Algae productivity of 39 g/(m2 day) in June–July was achieved at significant scale (18,000 L), while average daily productivity slightly in excess of 10 g/(m2 day) was demonstrated in the month of December. A protocol for low-cost algae harvesting and dewatering was developed, and the conversion of algal lipids—extracted from the harvested biomass—to diesel-range hydrocarbons via catalytic deoxygenation was demonstrated. Assuming an amortization period of 10 years, calculations suggest that the current cost of capturing and recycling CO2 using this approach will fall close to $1,600/ton CO2, the main expense corresponding to the capital cost of the photobioreactor system and the associated installation cost. From this it follows that future cost reduction measures should focus on the design of a culturing system which is less expensive to build and install. In even the most optimistic scenario, the cost of algae-based CO2 capture is unlikely to fall below$225/ton, corresponding to a production cost of ~$400/ton biomass. Hence, the value of the algal biomass produced will be critical in determining the overall economics of CO2 capture and recycle
