Asymptotic Numbers: I. Algebraic Properties, Todor D. Todorov

Mathematics

The set of asymptotic numbers A introduced in Refs. [1] and [3] is a system of generalized numbers including the system of real numbers R, as well as infinitely small (infinitesimals) and infinitely large numbers. The purpose of this paper is to study in detail the algebraic properties of A which are a little unusual, in a cenain sense, as compared with the known algebraic structures (rings. fields, etc.) This is necessary for the investigation of the class of asymptotic functions [2.4], which are on their part, generalized functions similar to the distributions of Schwartz but allowing the operation of …

The Determination Of Trace Levels Of Aluminum By Differential Pulse Polarography, Geraldine S. P. Ritchie, Alan M. Posner, Ian M. Ritchie

Food Science and Nutrition

The direct determination of aluminium in aqueous solutions by differential pulse polarography is described. If the pH is carefully controlled to 4.00 ± 0.01, there is a linear relationship between the peak height of the polarographic wave and the aluminium concentration up to 2.5 × 10^-5 mol dm^-3. The coefficient of variation is about 4% at the 10^-5 mol dm^-3 level. With increasing aluminium concentrations, the relationship ceases to be linear, and above 9 × 10^-5 mol dm^-3, the peak splits, probably because of hydrolysis and polymerisation. Na⁺, NH_{4 …}

Asymptotic Numbers: Ii. Order Relation, Infinitesimals And Interval Topology, Todor D. Todorov

Mathematics

It has been shown in [8] that the set of asympototic numbers A is a system of generalized numbers including isomorphically the set of real numbers R, as well as the field of formal power (asymptotic) series. In the present paper, which is a continuation of [8], an order relation in A is introduced due to A turning out to be a totally-ordered set. The consistency between the order relation and the algebraic operations in A is investigated and in particular, it is shown that the inequalities in A can be added and multiplied as in the set of …

Electronic Fuel Injection Techniques For Hydrogen Powered I.C. Engines, Art Maccarley, W. D. Van Vorst

Electrical Engineering

Numerous studies have demonstrated the advantages of hydrogen as a fuel for Otto Cycle engines due to high thermal efficiency and low exhaust pollutant levels. Characteristic of hydrogen engine operation using premixed intake charge formation is a problem of pre-ignition resulting in an intake manifold “backfire”. Additional problems include high NO_x production when using certain equivalence ratios and power output degradation due to low fuel energy/volume density.

Techniques for direct and port fuel injection are discussed as means for overcoming these problems. Emphasis is placed on the need for total engine control, integrating control of fuel injection, ignition timing, …

Broadcast Antenna Array Computer Program, Doren Rosenthal

Electrical Engineering

The purpose of this project was to design a computer program to evaluate the relative field strength patterns of directional broadcast antenna arrays. Through this project, I was exposed to research, design, test and personal contact with men who have experience in the field.

The program was successfully demonstrated with test data on actual broadcast antenna arrays and a deadline met. Proof of theorems may be found in textbooks and are not included in this paper. This paper is oriented strictly towards applications.
