Using the multisensory approach of touch math to teach basic mathematical operations to students with significant disabilities
The current study examines how the multisensory approach of the Touch Math program is used in a school that educates students with significant disabilities to improve their basic operation addition skills. The students who participated in this study struggled with traditional teaching of basic …

Using -2 as a base for a number system to realize a computer
The first section demonstrates the mathematical feasibility of using -2 for a base as a possible number system in a computer. All arithmetic operations are defined and many examples are given. The second section shows how the various mathematical operations might be realized in an actual computer. …

Drawing Out Notations
… As this series of figures are elaborated by mathematical operations, the complex nature of their combination removes apparent identity and synthesizes a simultaneous presence which is difficult to name. The drawings serve as a form of notation, similar to sheet music. As notation they aim to …

An Interactive Approach to Generating SQL Queries from Natural Language
… allows users to use a natural language and mathematical operations with a minimal structure. We evaluated nalini with a first-use study with five participants, where participants were asked to generate queries from the TPC-H decision support benchmark. Our study showed that users were able …

The design, construction, and testing of a reactimeter
… but it requires a separate program of elementary mathematical subroutines. This second program performs all the mathematical operations and requires 1.25 K of memory.

Application of the hodograph method to several problems in fluid mechanics
… provided it is possible to carry out the mathematical operations. It must be realized that the hodograph method gives only approximate solutions. However, the hodograph solution gives a more accurate description of a fluid flow than does the classical solution since the hodograph method …

Vulnerabililty Analysis of Multi-Factor Authentication Protocols
… that the use of computationally intensive mathematical operations in password authentication protocols can lead to security vulnerabilities in those protocols. In order to test this hypothesis: 1. A generalized algorithm for cryptanalysis was formulated to perform a clogging attack (a …

An analog VLSI front end for pulse oximetry
… eliminates the need of performing some of the mathematical operations which are traditionally done in digital domain to calculate oxygen saturation and allows for a very area-efficient all-analog implementation. The need for an ADC and a DSP is thus completely eliminated.

Analogue simulation
… a device which counts and performs other operations using discrete voltage levels (this noise being no problem). The analogue computer operates continuously at all voltages (limited by the power supply), from zero frequency upwards to a certain limitation depending upon the equipment. Due …

The relationship of unmanipulated self-reports of children's internalized representation of numbers to mathematics achievement
… not of sufficient difficulty to relate to any mathematical operations or logio-mathematical thinking for older children. The ability of children to produce reproductive images which have varying degrees of spatio-organizational patterns was demonstrated by this study. Future studies need to …
