Do Price Uncertainties Affect the Use of Policy Flexibilities? The Selection of Sensitive Products in WTO Agricultural Negotiations

In a context in which price uncertainty is likely to increase, expected market trends need to be taken carefully into account while negotiating international trade policy rules. This paper aims at analyzing what is their influence on the use of policy flexibilities in the context of WTO agricultural negotiations. In particular, within the market access pillar, we focus on the selection of sensitive products. Our model, TRIMAG (Tariff Reduction Impact Model for Agriculture), defined at the 8-digit level, optimizes the domestic agricultural value added subject to a maximum number of sensitive tariff lines, accounting for various future international price scenarios. Furthermore, we test the use of alternative options for the implementation of “tariff simplification”. Findings confirm that the future expected development of world and domestic prices plays an important role in the selection of sensitive products, and that tariff simplification doesn’t affect the results, if provisions to ensure the neutrality of the exercise are put in place. Furthermore, TRIMAG can be considered as a tariff aggregation tool that can be linked to agricultural simulation models that operate at a higher level of aggregation.WTO agricultural negotiations, market access, sensitive products, International Relations/Trade, F13, Q17,

Cogeneration Technology Alternatives Study (CTAS). Volume 5: Cogeneration systems results

The use of various advanced energy conversion systems is examined and compared with each other and with current technology systems for savings in fuel energy, costs, and emissions in individual plants and on a national level. About fifty industrial processes from the largest energy consuming sectors were used as a basis for matching a similar number of energy conversion systems that are considered as candidate which can be made available by the 1985 to 2000 time period. The sectors considered included food, textiles, lumber, paper, chemicals, petroleum, glass, and primary metals. The energy conversion systems included steam and gas turbines, diesels, thermionics, stirling, closed cycle and steam injected gas turbines, and fuel cells. Fuels considered were coal, both coal and petroleum based residual and distillate liquid fuels, and low Btu gas obtained through the on site gasification of coal. The methodology and results of matching the cogeneration energy conversion systems to approximately 50 industrial processes are described. Results include fuel energy saved, levelized annual energy cost saved, return on investment, and operational factors relative to the noncogeneration base cases

An \~{O}(n2)(n^2) Time Matrix Multiplication Algorithm

We show, for the input vectors $(a_0, a_1, ..., a_{n-1})$ and $(b_0, b_1, ..., b_{n-1})$, where $a_i$'s and $b_j$'s are real numbers, after \~{O}$(n)$ time preprocessing for each of them, the vector multiplication $(a_0, a_1, ..., a_{n-1})(b_0, b_1, ..., b_{n-1})^T$ can be computed in \~{O}$(1)$ time. This enables the matrix multiplication of two $n\times n$ matrices to be computed in \~{O}$(n^2)$ time.Comment: Version 11 and Version 12 section 2 laid the foundation of this algorithm but has a problem unresolved. This version corrects the problem in Version 11 and Section 2 of Version 1

Parallel addition in non-standard numeration systems

We consider numeration systems where digits are integers and the base is an algebraic number $\beta$ such that $|\beta|>1$ and $\beta$ satisfies a polynomial where one coefficient is dominant in a certain sense. For this class of bases $\beta$, we can find an alphabet of signed-digits on which addition is realizable by a parallel algorithm in constant time. This algorithm is a kind of generalization of the one of Avizienis. We also discuss the question of cardinality of the used alphabet, and we are able to modify our algorithm in order to work with a smaller alphabet. We then prove that $\beta$ satisfies this dominance condition if and only if it has no conjugate of modulus 1. When the base $\beta$ is the Golden Mean, we further refine the construction to obtain a parallel algorithm on the alphabet $\{-1,0,1\}$. This alphabet cannot be reduced any more

Development of land based radar polarimeter processor system

The processing subsystem of a land based radar polarimeter was designed and constructed. This subsystem is labeled the remote data acquisition and distribution system (RDADS). The radar polarimeter, an experimental remote sensor, incorporates the RDADS to control all operations of the sensor. The RDADS uses industrial standard components including an 8-bit microprocessor based single board computer, analog input/output boards, a dynamic random access memory board, and power supplis. A high-speed digital electronics board was specially designed and constructed to control range-gating for the radar. A complete system of software programs was developed to operate the RDADS. The software uses a powerful real time, multi-tasking, executive package as an operating system. The hardware and software used in the RDADS are detailed. Future system improvements are recommended
