Determining the feasibility of making bamboo charcoal pencil leads in developing countries using graphite pencil lead manufacturing processes
… the processes and tools necessary to make pencils from bamboo, rather than wood. The communities that launch this enterprise will need to outsource the glue and graphite leads required to complete the pencils. Waste is generated by cutting processes used to dimension the bamboo to …

Equivalency of paper-pencil tests and computer-administered tests.
… versions of a multiple choice paper-pencil test equivalent? This study determined whether there were any significant differences between taking a traditional pencil-paper test and taking the same test using a computer. The literature has shown that there are intervening variables that …

Comparison of Computer Testing versus Traditional Paper and Pencil Testing
… the Block One Tests in the traditional paper and pencil form. Another six classes containing a total of 118 students took the same Block One Tests on computers. A confidence level of .99 and level of significance of .01 was established. An independent samples t-test was conducted on the sample. …

A Methodology for the Design of Spaceborne Pencil-Beam Scatterometer Systems
… An alternate approach, the conically-scanning "pencil-beam" scatterometer technique, alleviates many of the problems encountered with earlier systems and provides additional measurement capability. Due to these advantages, the pencil-beam approach has been selected by NASA as the basis for …

Pencil beam dose calculation for proton therapy on graphics processing units
… the most computationally expensive step of the pencil beam algorithm to run on graphics processing units. As a result, it was demonstrated how the kernel superposition operation, or convolution with a spatially varying kernel, can be efficiently implemented using a novel scatter-based approach. …

Optimizing Classification Decisions for Paper-and-Pencil and Computer Adaptive Tests
Throughout the social sciences, tests have been used for two primary - and different - purposes: a) to estimate where an examinee is located on an ability/trait continuum (e.g., intelligence tests), or b) to classify an examinee as either above or below a particular point on the ability continuum …

The Development of a Paper-and-Pencil Measure of Complex Cognitive-Perceptual Aptitude
… for helicopter pilot training. The paper-and-pencil test was designed to provide measures of both static and dynamic (i.e., learning) ability under different levels of complexity. The secondary research purpose was to develop a battery of eight psychometric tests to assess other abilities that …

Design and fabrication of a pencil shoulder cutting device for a novel endcap
The pencil shoulder cutting device is a stepper motor driven mechanism to cut a small groove into the end of a pencil, which is needed for a novel seed-capsule endcap for a new pencil called Sprout. The pencil was developed by a team of MIT graduate students, and the shoulder cutting device is one …

The design and manufacture of mass production equipment for a pencil with a seed
… equipment envisioned to produce Sprout, a pencil with a seed. This pencil concept was developed by MIT students a successful round of funding and first production run through Kickstarter. The goals for Autosprout are to fully automate the manufacturing process, and to reduce the …

The development and validation of a paper and pencil achievement test in automotive mechanics
… study was to develop and validate a paper and pencil automotive mechanics achievement test and determine the feasibility of measuring the competence of mechanics using this instrument rather than the traditional performance test. It involved: 1) the selection of a number of accepted performance …

Analysis of 2-axis pencil beam sonar microbathymetric measurements of mine burial at the Martha’s Vineyard Coastal Observatory
… larger, 16 total object investigation. A 2-axis pencil beam sonar was deployed concurrently with the mine to obtain microbathymetric measurements of the scour pit development and the progression of mine burial. Data correction techniques to correct for beam pattern induced bathymetry errors and a …
