This thesis analyzes the simulation of a Single Channel Ground and Airborne Radio System (SINCGARS), currently in use by the United States Army. Although this radio was mainly designed as a voice radio, it also has the capability to transmit data messages. The amount of voice traffic which is capable of flowing through the channel, without causing detrimental effects to users, is studied. The struggle to transmit data versus voice is considered. Various other factors capable of influencing performance are explored. These consist of net access delay, net size, frequency of information transmission, and most importantly, data message transmission delays. The radio net is modeled in EXTEND, a commercial software package. The program simulates preselected and quantified data as well as coded voice data. The data is then processed through the single radio channel. Message transmission delays are calculated by EXTEND and examined for individual users. The primary contribution of this thesis is the development of an analytical approximation to estimate message transmission delays. The analysis is based on simulated data from EXTEND. A general expression is derived for each member, or user, on the SINCGARS net. This is an effort not only to simplify and generalize the method of estimating delay, but it also serves to shorten the amount of time spent on analysis, by reducing the dependence upon simulation. Applications of this research include the analysis of SINCGARS, under the Inter-Vehicular Information System (IVIS) protocol, using simulation and statistical approximations. If the performance of a new system can be accurately evaluated using a general expression, thus eliminating the need for repeated simulations, performance and system analysis time can be significantly reduced. / M.S.

Past psychophysiological research has led many investigators to believe that perceived effort during exercise is lower with greater active muscle mass (Hagan, et al., 1983; Sargeant & Davies, 1973; Shephard, et al., 1992; Stenberg, et al., 1967), presumably because the effort is distributed to more muscle tissue. The purpose of this investigation was to compare the Ratings of Perceived Exertion (RPE) of college-age females during steady-state leg-only (LE) and combined arm-and-leg exercise (ALE) using the 15-point Borg RPE scale. Volunteer subjects were 16 healthy, physically active female students, mean age 21.0 years (SE 0.33) and a percent body fat of 22.1 (SE 1.1). Each subject completed a graded maximal exercise test on a Monark 880 LE cycle ergometer. Exercise intensity during two subsequent 30-minute exercise treatments was then maintained at the HR corresponding to 70% of the subject's tested functional capacity (VO2max). The exercise treatments were two randomized bouts separated by at least 48 hours but not more than one week, one each using a Monark 880 cycle ergometer (LE) and a Schwinn AirDyne (ALE). Mean RPEs were 13.7 (SE 0.2) for the LE session, and 13.0 (SE 0.3) for the ALE session. Mean heart rates were 172.8 bpm (SE 1.18) for the LE session, and 170.6 bpm (SE 1.26) for the ALE session. Mean VO₂s were 30.7 ml/kg/min (SE 0.76) for LE and 30.1 ml/kg/min (SE 0.68) for ALE. Workload means were 120.0 Watts (SE 3.83) for LE and 127.7 Watts (SE 4.11) for ALE. Repeated measures ANOVA revealed no significant differences between the two modalities for RPE (p < 0.07) or VO₂ (p < 0.12), but significant differences for HR (p < 0.006) and workload (p < 0.0003). Tukey's post-hoc test for simple effects determined that time effects were significant (p < 0.0001) regardless of modality, with RPE and HR measurements at minutes five and ten differing from those at minutes 15, 20, 25, and 30 (p < 0.05) during both LE and ALE bouts. The results of this investigation indicate that no significant perceived effort difference exists between these LE and ALE modalities over a 30-minute exercise bout at the same HR-regulated intensity. / M.S.

La presente investigación busca analizar qué tipos de interacción surgieron entre las ONG feministas Centro de la Mujer Peruana Flora Tristán, el Movimiento Manuela Ramos y el Estado –con respecto a los derechos sexuales y reproductivos de las mujeres en el Perú– durante su participación en la Mesa Tripartita de Seguimiento de la Conferencia de Población y Desarrollo, El Cairo (CIPD), que tuvo lugar entre los años 1997-2000. Dicha Mesa, instaurada durante el segundo gobierno de Alberto Fujimori, estuvo constituida, además, por representantes de la Cooperación Internacional y la Academia. Este trabajo busca determinar cómo la Mesa Tripartita, en un contexto fuertemente influido por las agencias de Cooperación Internacional, generó interacciones entre el Estado y las ONG feministas CMP Flora Tristán y el Movimiento Manuela Ramos; interacciones que fueron cambiando entre el acercamiento y la cooperación, hasta producir una reconfiguración de las negociaciones debido al programa de Anticoncepción Quirúrgica Voluntaria (AQV) que causó una serie de denuncias por esterilizaciones forzadas durante el segundo gobierno de Alberto Fujimori. Cabe mencionar, que esta tesis enfocará su análisis desde la perspectiva de los distintos integrantes involucrados de la sociedad civil. / Tesis

Gilles Deleuze makes a paradox of ethics. Throughout his oeuvre, he establishes polarities (affirmation versus negation, difference versus identity, rhizome versus arborescence, etc.), and demonstrates rhetorically a preference for one pole over the other. This would seem to constitute, if not an obligation or imperative, at least an urgency, a suggestion that those who find his discussion compelling should favor that one pole and act in such a way as to promote it or move toward it. However, for a variety of reasons, it proves difficult or even impossible to put this 'ethics' into practice. / This thesis examines the reasons for this impossibility through close readings of four of Deleuze's texts, Nietzsche and Philosophy, Difference and Repetition, Anti-Oedipus, and A Thousand Plateaus. In each text, I highlight the polarities, showing where Deleuze's expressed preference lies. Then I demonstrate the obstacles to an implementation of this preference. Moving from text to text, I trace how Deleuze's attempts to deal with the question of ethics change over his career, becoming more sophisticated and opening up new problems and possibilities. / Although the nature of the paradox of ethics varies from case to case, I discover at least two difficulties in general. The first concerns the move from the abstract to the concrete: Deleuze often expresses a polarity in abstract or metaphysical terms, which collapses when extended into the concrete. Metaphysically, affirmation is sharply distinguished from negation; where affirmation creates difference, negation levels difference to produce homogeneity. Practically, however, it is impossible to locate this distinction in the world; no person, place, thing, or event can be said to be either affirmative or negative. / This relates closely to the second general difficulty, the insertion of the subject. Even if it were possible to make a practical distinction between two poles of value, it is impossible to locate the subject in relation to those poles. That is, even if the world can be said to behave affirmatively or negatively, the subject is only accidentally related to this behavior, and so ethics becomes a purely ontological matter, bearing no relation to the will or intention of a subject.

<p>Software complexity metries have long been used in the procedural programming paradigm. Existing OOP metrics do not address how a class's relation to other classes in the inheritance hierarchy affect it's maintenance needs. This research proposes a new OOP metric, Hierarchy Corrected Metric (HCM) that does address a class's relation to others in the hierarchy. HCM uses the values of the standard OOP metrics for each class plus knowledge of the class inheritance hierarchy to anive at a revised complexity measurement for each class. That measurement reflects not only internal complexity for the class but also the influence of other classes in the hierarchy to the complexity of the class. Using data from a commercial system HCM was shown to correlate with maintenance better than existing OOP metrics.</p> / Master of Science

<p>The objective of this project was threefold. Initially, interviews with tourists, visitor center staff, and tourism officials were conducted to determine if the proposed ITS technologies could be successfully used to promote tourism in southwest Virginia. From these interviews, a list of user needs was developed. Finally, possible applications of the ITS technologies were recommended.</p> / Master of Science
