DSP Guitar FX Pedal

A guitar effects (FX) pedal, also referred to as a stomp box, manipulates the electric signal produced by guitars to produce a variety of different sounds for the application of music. Musicians use guitar effects to produce sonically different and interesting sounds for the sake of performance, creation, and art. Although the different types of effects are numerous, the basic effects fall into either distortion, modulation, or delay. The use of guitar pedals allows the musician to accurately perform desired pieces of music or compose new songs. The current guitar pedal market includes many effects by many manufacturers, however many of the pedals cost over $100 and include a minimal selection of effects. Although there are many ways to manipulate audio signals, Digital Signal Processing offers an inexpensive way to produce multiple effects using minimal amounts of hardware. An inexpensive, good sounding pedal that includes multiple effects would allow more musicians to use effects in their music

A study of the relationship between transliminality and interpersonal difficulties: Is the severity of interpersonal difficulties related to sensitivity to unconscious psychological material?

Despite a growing literature supporting the view of a dynamic unconscious, there have been few attempts to empirically investigate the role of unconscious processes in relation to existing models of psychopathology. In this study, the concept of transliminality (defined as ‘a hypothesised tendency for psychological material (trans) thresholds (limines) into or out of consciousness’, Thalbourne & Houran, 2000, p. 853) and a standardised self-report measure of this construct were used to explore relationships between unconscious processes and interpersonal difficulties. Transliminality and two of the central components of the mentalization-based model of interpersonal difficulties – attachment hyperactivity and mentalization, were examined. The mentalization model was seen as a fitting context for this investigation given that mentalization draws on attachment theory, psychoanalytic principles and makes reference to unconscious processes. Using standardised self-report measures this study attempted to answer two research questions. Firstly, is transliminality related to interpersonal difficulties and what is the nature of this relationship? Secondly, does transliminality mediate the effects of mentalization and attachment hyperactivation on interpersonal difficulties? These questions were investigated using a clinical sample recruited from two NHS specialist adult psychological therapies services (N = 16) receiving referrals for those between the age of 18 to 65 and a non-clinical sample (N = 60). The data from the non-clinical sample revealed that transliminality, mentalization and attachment hyperactivity were all predictors of interpersonal difficulties. The variance uniquely accounted for by each predictor and the lack of relationships between them, was seen as a reflection of these constructs representing distinct psychological processes that contribute to interpersonal difficulties. Kernberg’s (1975) notion of borderline continuum and Kelly’s (1955, 1977) personal construct theory were used to explain the role of translimality. The etiological pathways common to psychosis and interpersonal difficulties were seen as a possible explanation as to why high levels of transliminality are found in both of these populations. It is hypothesised that a necessity to revise constructs more frequently in response to traumas is facilitated by transliminal states, which allow construct boundaries to shift. Clinical implications and future research possibilities are considered in light of these findings

On Micropolitics: Climate adaptation and Indigenous governance in Western Alaska

Climate adaptation for Indigenous communities is not as simple as making good policy; it is equally about how policy is implemented and how collaboration unfolds between settler governments and Indigenous stakeholders. Rural Alaska Native villages are among the most environmentally threatened communities in the United States. Their ability to effectively manage environmental change and preserve sovereignty depends upon successful collaboration with a range of stakeholders, especially federal agencies. For more than two decades, academics and government agencies have documented a consistent pattern of failures, particularly by federal actors, to effectively manage adaptation challenges. These obstacles are sometimes misrepresented as policy failures. While poor policy is certainly involved in these poor outcomes, this paper highlights a set of barriers to successful collaboration that are not policy issues, per se, but rather micropolitical issues; that is, they pertain to the conduct of government in the context of Tribal relationships. Unaddressed, these micropolitical issues have created obstacles to Alaska Native communities’ self-determination as they adapt to a changing landscape. These barriers are explored in a case study drawn from Typhoon Merbok, which struck Western Alaska in 2022, and empirically grounded in a series of interviews and participant observation with experts, elders, elected officials, and Tribal staff. This article concludes with several concrete recommendations to improve the practice of domestic diplomacy between Indigenous communities and colonial governments

This final report documents the activities performed during the research period from April 1, 1996 to September 30, 1997. It contains three papers: Carrier Phase GPS and Computer Vision for Control of an Autonomous Helicopter; A Contestant in the 1997 International Aerospace Robotics Laboratory Stanford University; and Combined CDGPS and Vision-Based Control of a Small Autonomous Helicopter

Generating Topological Information from a "Bucket of Facets"

The STL de facto data exchange standard for Solid Freefonn F*brication represents CAD models as a collection of unordered triangular planar facels. No topological connectivity information is provided; hence the term "bucket of facet." Such topological information can, however, be quite useful for performing model validity checking and speeding subsequent processing operations such as model slicing. lfhis paper discusses model topology and how to derive it given a collection of unordered tri,ngular facets which represent a valid model.Mechanical Engineerin
