Algae biodiesel - a Feasibility report
Chemistry Central Journal, 2012Co-Authors: Chapin Gregor, Yuanjie Liang, Dawei Tang, C. TweedAbstract:Background Algae biofuels have been studied numerous times including the Aquatic Species program in 1978 in the U.S., smaller laboratory research projects and private programs. Results Using Molina Grima 2003 and Department of Energy figures, captial costs and operating costs of the closed systems and open systems were estimated. Cost per gallon of conservative estimates yielded $1,292.05 and $114.94 for closed and open ponds respectively. Contingency scenarios were generated in which cost per gallon of closed system biofuels would reach $17.54 under the generous conditions of 60% yield, 50% reduction in the capital costs and 50% hexane recovery. Price per gallon of open system produced fuel could reach $1.94 under generous assumptions of 30% yield and $0.2/kg CO_2. Conclusions Current subsidies could allow biodiesel to be produced economically under the generous conditions specified by the model.

Feasibility Conditions for Interference Alignment
Global Telecommunications Conference, 2009. GLOBECOM 2009. IEEE, 2009Co-Authors: Cenk M Yetis, Tiangao Gou, S.a. Jafar, Ahmet H. KayranAbstract:The degrees of freedom (DoF) of K-user MIMO interference networks with constant channel coefficients are not known in general. Determining the Feasibility of a linear interference alignment is a key step toward solving this open problem. Our approach in this paper is to view the alignment problem for interference networks as a multivariate polynomial system and determine its solvability by comparing the number of equations and the number of variables. Consequently, we divide the interference networks into two classes proper and improper, where interference alignment is and is not achievable, respectively. An interference network is called proper if the cardinality of every subset of equations in the corresponding polynomial system is less than or equal to the number of variables involved in that subset of equations. Otherwise, it is called improper. Our intuition in this paper is that for general channel matrices, proper systems are almost surely feasible and improper systems are almost surely infeasible. We prove the direct link between proper (improper) and feasible (infeasible) systems for some important cases, thus significantly strengthening our intuition. Numerical simulation results also support our intuition.
