"To improve learning in higher education, the primary focus should be on engaging students in a process that best enhances their learning--a process that includes feedback on the effectiveness of their learning efforts. " [Kolb & Kolb, 2005] If that is true of most subjects of higher education, it is doubly so for teaching programming in the college classroom. Learning programming and related topics requires experience and personal commitment. It requires effort, often prolonged effort, over time. Unfortunately, students (and business students in particular) regularly seek ways to minimize their investment of time and maximize their grade outcome. [Parks-Leduc, et. al., 2022] The only recourse for MIS/IS instructors is, then, to create graded programming assignments with a variety and quantity sufficient to coerce students into investing the time necessary for learning. However, grading student programs is a labor-intensive responsibility for faculty members. It is tedious and error prone. Grading programs consistently and in a timely manner is often a challenge for faculty members. Delays in graded feedback are detrimental to student learning. This paper presents an innovative tool called Grade-O-Matic. It can be used by both students and instructors to grade programs quickly and in large quantities. By using the Grade-O-Matic tool, faculty members can assign more graded programming assignments, and students can get immediate feedback on their work before turning it in to be graded. This paper describes the Grade-O-Matic tool, and its creation, from its inception to its current state using terminology of the Design Science Research Methodology (DSRM) [Peffers, et. al., 2007]. The distinctives of the tool, and how it is different from similar efforts, are noted. The paper concludes with anecdotal evidence to support the claim that the tool, and the immediacy it affords, supports student learning. Also noted are generalized principles that may support future efforts. [ABSTRACT FROM AUTHOR]

This paper shows the design of a fuzzy controller to maintain stoichiometric air-fuel mixture in an internal combustion engine. This objective is very important for the performance in a vehicle, to achieve a stoichiometric ratio for reducing emissions, improving energetic efficiency and power generation, with a reduction in the operating temperatures of an engine. The mixture control is accomplished with precision devices led by the electronic control unit (ECU), which is essentially a logical device that is responsible for maintaining a stoichiometric air-fuel ratio. We will discuss the mathematical modeling of an internal combustion engine, showing a fuzzy control scheme, which consists in a predictive (forward control) and other corrective (Feedback control) action. In this first phase of the project we present the simulation results using the Simulink of Matlab®. [ABSTRACT FROM PUBLISHER]

GPS based techniques allow a highly accurate attitude determination when using carrier phase measurements. However, these techniques require the determination of the integer carrier phase ambiguities. This is a problem that is usually addressed in a context of dual frequency receivers. Due to the high cost of these receivers, strong motivation exists to explore these techniques with cheaper L1 single frequency receivers. In this paper, a high accuracy attitude determination technique is proposed, based on multiple baselines, using low cost single frequency L1 GPS receivers. Test results with real data are presented.

Study of the Λ and Λ hyperon production in the HERMES experiment is discussed. The data were collected using a 27.6 GeV longitudinally polarized positron (or electron) beam of the HERA accelerator and a polarized or unpolarized target. The transverse polarizations (perpendicular to the production plane) of the Λ and Λ hyperons have been measured. The spin transfer KLL from the longitudinally polarized target has been found for inclusively detected Λ and Λ events. Longitudinal spin transfer DLL from the beam to the Λ hyperon in the deep inelastic scattering regime has been analyzed. The DLL for Λ has been measured for the first time. [ABSTRACT FROM AUTHOR]

The Carolina Gay Association (CGA) at the University of North Carolina first published its newsletter, Lambda, in the fall of 1976. It was then the only sexual minority periodical produced in North Carolina. More than thirty years later, UNC's Gay, Lesbian, Bisexual, Transgendered—Straight Alliance continues publishing Lambda, now the oldest campus magazine for sexual minority students in the country. The research presented in this paper aimed to determine the role that the contextual elements of time period, location, and the goals of its parent organization, played in the establishment and the original character of Lambda. Results are based on a content analysis of the newsletter's first three years of publication, and on oral histories of three individuals who were involved in the newsletter's early existence. The findings indicate that the establishment and initial character of the newsletter were (1) informed by the gay rights movement of the late 1960s and early 1970s; (2) facilitated by the political focus of the CGA; and (3) affected by the newsletter's location at a Southern university; but (4) shaped most uniquely by the overriding CGA concern to promote the healthy psychosocial development for homosexual individuals not only at UNC, but throughout North Carolina and the Southeast. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

The studies of hyperon production performed at COSY-11 are summarized. The results of the experiments in the reaction channels pp→pK+Λ, pp→pK+Σ0, and pp→nK+Σ+ are shown. Excitation functions from threshold up to about 90 MeV excess energies have been evaluated with high precision for the Λ and Σ0 production. The Λp and Σ0p final state interactions were extracted. The Σ+ production was measured at 13 and 60 MeV excess energies. [ABSTRACT FROM AUTHOR]
