The development of an optimized system of narcotic and explosive contraband mimics for calibration and training of biological detectors

Current commercially available mimics contain varying amounts of either the actual explosive/drug or the chemical compound of suspected interest by biological detectors. As a result, there is significant interest in determining the dominant chemical odor signatures of the mimics, often referred to as pseudos, particularly when compared to the genuine contraband material. This dissertation discusses results obtained from the analysis of drug and explosive headspace related to the odor profiles as recognized by trained detection canines. Analysis was performed through the use of headspace solid phase microextraction in conjunction with gas chromatography mass spectrometry (HS-SPME-GC-MS). Upon determination of specific odors, field trials were held using a combination of the target odors with COMPS. Piperonal was shown to be a dominant odor compound in the headspace of some ecstasy samples and a recognizable odor mimic by trained detection canines. It was also shown that detection canines could be imprinted on piperonal COMPS and correctly identify ecstasy samples at a threshold level of approximately 100ng/s. Isosafrole and/or MDP-2-POH show potential as training aid mimics for non-piperonal based MDMA. Acetic acid was shown to be dominant in the headspace of heroin samples and verified as a dominant odor in commercial vinegar samples; however, no common, secondary compound was detected in the headspace of either. Because of the similarities detected within respective explosive classes, several compounds were chosen for explosive mimics. A single based smokeless powder with a detectable level of 2,4-dinitrotoluene, a double based smokeless powder with a detectable level of nitroglycerine, 2-ethyl-1-hexanol, DMNB, ethyl centralite and diphenylamine were shown to be accurate mimics for TNT-based explosives, NG-based explosives, plastic explosives, tagged explosives, and smokeless powders, respectively. The combination of these six odors represents a comprehensive explosive odor kit with positive results for imprint on detection canines. As a proof of concept, the chemical compound PFTBA showed promise as a possible universal, non-target odor compound for comparison and calibration of detection canines and instrumentation. In a comparison study of shape versus vibration odor theory, the detection of d-methyl benzoate and methyl benzoate was explored using canine detectors. While results did not overwhelmingly substantiate either theory, shape odor theory provides a better explanation of the canine and human subject responses.

Modeling security and cooperation in wireless networks using game theory

This research involves the design, development, and theoretical demonstration of models resulting in integrated misbehavior resolution protocols for ad hoc networked devices. Game theory was used to analyze strategic interaction among independent devices with conflicting interests. Packet forwarding at the routing layer of autonomous ad hoc networks was investigated. Unlike existing reputation based or payment schemes, this model is based on repeated interactions. To enforce cooperation, a community enforcement mechanism was used, whereby selfish nodes that drop packets were punished not only by the victim, but also by all nodes in the network. Then, a stochastic packet forwarding game strategy was introduced. Our solution relaxed the uniform traffic demand that was pervasive in other works. To address the concerns of imperfect private monitoring in resource aware ad hoc networks, a belief-free equilibrium scheme was developed that reduces the impact of noise in cooperation. This scheme also eliminated the need to infer the private history of other nodes. Moreover, it simplified the computation of an optimal strategy. The belief-free approach reduced the node overhead and was easily tractable. Hence it made the system operation feasible. Motivated by the versatile nature of evolutionary game theory, the assumption of a rational node is relaxed, leading to the development of a framework for mitigating routing selfishness and misbehavior in Multi hop networks. This is accomplished by setting nodes to play a fixed strategy rather than independently choosing a rational strategy. A range of simulations was carried out that showed improved cooperation between selfish nodes when compared to older results. Cooperation among ad hoc nodes can also protect a network from malicious attacks. In the absence of a central trusted entity, many security mechanisms and privacy protections require cooperation among ad hoc nodes to protect a network from malicious attacks. Therefore, using game theory and evolutionary game theory, a mathematical framework has been developed that explores trust mechanisms to achieve security in the network. This framework is one of the first steps towards the synthesis of an integrated solution that demonstrates that security solely depends on the initial trust level that nodes have for each other.^

Teoría y práctica del neobarroco en Severo Sarduy

This dissertation analyzes the theory and practice of the Cuban postmodern writer Severo Sarduy (1937–1993) from his early adult years in Cuba to his exile period in Paris, France, where he lived until his death. By studying his narrative through the light of his theoretical essays, this paper demonstrates that the author created his own type of reading model—from and for Sarduy. His literary work is influenced by three major elements: (post)structuralism, psychoanalysis, and Buddhism, which combined form what Sarduy himself called the Neobarroque style. The Sarduyan writing is a transgressive exercise expressed through his concept of simulación. This style breaks with the traditional art concept of mimesis (the representation of reality in the western world), and therefore with the correspondence between the signifier and the signified. Sarduy does not intend to represent reality but to go beyond it, achieving by his technique of signifying exhaustion to represent absence itself. The Neobarroque of Severo Sarduy is an aesthetic of the empty signifier based on the reckless expenditure, and ultimately exhaustion, of the artifices of language that precipitates in a signifier chain towards the infinite. His language does not transmit a message but it signifies itself, that is, a means without an end. Paradoxically, this signifier chain produces an excess of metaphors beyond the material limits of language and its support, the page. The space beyond language is the hipertelic technique inherited by Sarduy from his literary master, José Lezama Lima. This is also the empty space of no signification or nonsense in which occurs the depersonalization of the speaking subject; in Buddhist terminology this becomes the dissolution of the ego. The Sarduyan language is determined by a Lacanian psychoanalytic erotic drive (pulsion) known as the Barroquean desire, a death drive which directly relates to the exile condition of the author. But the genesis of this desire lies in a primordial desire of encounter with his origin: mother, maternal language, paradise, God. That is the reason why Sarduy not only poses an aesthetic question but also an ontological one. This other dimension of the Sarduyan writing is based on a liberating drive that permeates all his work—an ontological liberation expressed through language. The empty space created in the text provides the subject with the possibility of fusion with the all. Ultimately, Sarduy strives for a language that goes beyond the symbolic limits towards a place of constant dissolution, evanesce, and death-horror vacui. This corroborates the Sarduyan statement: “la simulación enuncia el vacío y la muerte.”

The effect of domestic credit in the economic *development process

A commonly held view is that creation of excessive domestic credit may lead to inflation problems, however, many economists uphold the possibility that, generous domestic credit under appropriate conditions will result in increases of output. This hypothesis is examined for Japan and Colombia for the period 1950-1993.^ Domestic credit theories are reviewed since the times of Thornton and Smith, until the recent times of Lewis, McKinnon, Stiglitz and of Japanese economists like K. Emi, Tachi R. and others. It is found that in Japan of the Post-War period, efficient financial markets and the decisive role of the government in orienting investment decisions seem to have influenced positively the effectiveness of domestic credit as an output-stimulating variable. On the contrary, in Colombia the absence of the above features seems to explain why domestic credit is not very effective as an output-stimulating variable.^ Multiple regression analyses show that domestic credit is a strong explanatory variable for output increases in Japan and a weak one for Colombia's case in the studied period. For Japan the correlation depicts a positive relationship between the two variables with a decreasing rate very similar to a typical production function. Moreover, the positive decreasing rate is confirmed if net domestic credit is used in the correlations. For Colombia a positive relationship is also found when accumulated domestic credit is used, but, if net domestic credit is the source of correlations, the positive decreasing rate is not obtained.^ Granger causality tests determined causality from domestic credit to output for Japan and no-causality for Colombia at the 1% significance level; the differences are explained by: (1) The low development level of the financial system in Colombia. (2) The nonexistence of consistent domestic credit policy to foster economic development. (3) The lack of an authoritative orientation in the allocation of financial resources and the nonexistence of long range industrialization programs in Colombia that could channel productively credit resources. For the system of equations relating domestic credit and exports, the Granger causality tests determined no-causality between domestic credit and exports for both Japan and Colombia also at the 1% significance level. ^

A study of branching fluid networks for enhancing the performance of thermal -fluid devices

Compact thermal-fluid systems are found in many industries from aerospace to microelectronics where a combination of small size, light weight, and high surface area to volume ratio fluid networks are necessary. These devices are typically designed with fluid networks consisting of many small parallel channels that effectively pack a large amount of heat transfer surface area in a very small volume but do so at the cost of increased pumping power requirements. ^ To offset this cost the use of a branching fluid network for the distribution of coolant within a heat sink is investigated. The goal of the branch design technique is to minimize the entropy generation associated with the combination of viscous dissipation and convection heat transfer experienced by the coolant in the heat sink while maintaining compact high heat transfer surface area to volume ratios. ^ The derivation of Murray's Law, originally developed to predict the geometry of physiological transport systems, is extended to heat sink designs which minimze entropy generation. Two heat sink designs at different scales are built, and tested experimentally and analytically. The first uses this new derivation of Murray's Law. The second uses a combination of Murray's Law and Constructal Theory. The results of the experiments were used to verify the analytical and numerical models. These models were then used to compare the performance of the heat sink with other compact high performance heat sink designs. The results showed that the techniques used to design branching fluid networks significantly improves the performance of active heat sinks. The design experience gained was then used to develop a set of geometric relations which optimize the heat transfer to pumping power ratio of a single cooling channel element. Each element can be connected together using a set of derived geometric guidelines which govern branch diameters and angles. The methodology can be used to design branching fluid networks which can fit any geometry. ^

Public Service Motivation in Public and Nonprofit Service Providers: The Cases of Belarus and Poland

The work motivation construct is central to the theory and practice of many social science disciplines. Yet, due to the novelty of validated measures appropriate for a deep cross-national comparison, studies that contrast different administrative regimes remain scarce. This study represents an initial empirical effort to validate the Public Service Motivation (PSM) instrument proposed by Kim and colleagues (2013) in a previously unstudied context. The two former communist countries analyzed in this dissertation—Belarus and Poland— followed diametrically opposite development strategies: a fully decentralized administrative regime in Poland and a highly centralized regime in Belarus. The employees (n = 677) of public and nonprofit organizations in the border regions of Podlaskie Wojewodstwo (Poland) and Hrodna Voblasc (Belarus) are the subjects of study. Confirmatory factor analysis revealed three dimensions of public service motivation in the two regions: compassion, self-sacrifice, and attraction to public service. The statistical models tested in this dissertation suggest that nonprofit sector employees exhibit higher levels of PSM than their public sector counterparts. Nonprofit sector employees also reveal a similar set of values and work attitudes across the countries. Thus, the study concludes that in terms of PSM, employees of nonprofit organizations constitute a homogenous group that exists atop the administrative regimes. However, the findings propose significant differences between public sector agencies across the two countries. Contrary to expectations, data suggest that organization centralization in Poland is equal to—or for some items even higher than—that of Belarus. We can conclude that the absence of administrative decentralization of service provision in a country does not necessarily undermine decentralized practices within organizations. Further analysis reveals strong correlations between organization centralization and PSM for the Polish sample. Meanwhile, in Belarus, correlations between organization centralization items and PSM are weak and mostly insignificant. The analysis indicates other factors beyond organization centralization that significantly impact PSM in both sectors. PSM of the employees in the studied region is highly correlated with their participation in religious practices, political parties, or labor unions as well as location of their organization in a capital and type of social service provided.

Implementation of X-ray diffraction in the measurement of residual thermal strains

Microelectronic systems are multi-material, multi-layer structures, fabricated and exposed to environmental stresses over a wide range of temperatures. Thermal and residual stresses created by thermal mismatches in films and interconnections are a major cause of failure in microelectronic devices. Due to new device materials, increasing die size and the introduction of new materials for enhanced thermal management, differences in thermal expansions of various packaging materials have become exceedingly important and can no longer be neglected. X-ray diffraction is an analytical method using a monochromatic characteristic X-ray beam to characterize the crystal structure of various materials, by measuring the distances between planes in atomic crystalline lattice structures. As a material is strained, this interplanar spacing is correspondingly altered, and this microscopic strain is used to determine the macroscopic strain. This thesis investigates and describes the theory and implementation of X-ray diffraction in the measurement of residual thermal strains. The design of a computer controlled stress attachment stage fully compatible with an Anton Paar heat stage will be detailed. The stress determined by the diffraction method will be compared with bimetallic strip theory and finite element models.

Heidegger e a técnica moderna

The general objective of this research is to clarify and discuss the original contribution of Martin Heidegger's philosophical reflection on the essence of modern technique. For this purpose, it was structured the interpretative course of this dissertation in two essential moments. At first, we present Heidegger's interpretation of the essence of the modern age which, in turn, will be recognized from the metaphysical foundation that establishes the essence of modern science: the subjectivity that represents, calculates, manages and produces the real. We will see which, in this context, modern science was still thought close to the modern technology, what will change considerably from the writings of the post-war, in which Heidegger thinks modern science from a much broader and essential process in that the essence of the technique has already been unfolding. Thus, in a second moment, we will analyze how, for Heidegger, the modern metaphysics of subjectivity reached its completion at the time of modern art from the principle of control and planning of entities in general (Gestell), revealing the nontechnical sense of the technique (beyond the anthropological, humanistic and instrumental view) as well as the threatening character of modern technique in its conversion project of the entity from the reserve fund (Bestand).

The mermaid series of Elizabethan and Jacobean dramatists (1887-1909): a literary and critical history

The Mermaid Series (1887-1909) edited by Havelock Ellis was a major watershed in appreciation of Elizabethan and Jacobean drama. Before it appeared plays were available to general readers in scattered anthologies, large expensive collected editions or in expurgated selections which included only the more lyrical speeches and memorable scenes. Criticism of the drama followed suit; the majority of critics concentrated on the sections which appealed to the romantic and sentimental tastes of nineteenthcentury readers. The two men who conceived the Mermaid Series, John Addington Symonds and Havelock Ellis, approached the drama differently from their contemporaries; Symonds studied a play as a whole work of art and Ellis concentrated on its view of life. Both were unsatisfied with the "select beauties", fragmented approach and wanted readers to have the best plays in their entirety easily available in handy, inexpensive editions. Symonds's awareness of the drama as theatre was combined with a historical perspective allowing him to judge the drama in relation to its own time. He made a lasting but hitherto underestimated contribution to study of Beaumont and Fletcher, Dekker, Marlowe, and Ford. Ellis's work on the drama is overshadowed today by his studies of sex but his concentration on ideas and appreciation of unconventional behaviour enabled him to formulate new views on Ford, Middleton and Chapman. The two other major editors to work on the series, A. C. Swinburne and Arthur Symons had more conventional nineteenth-century approaches. Both were impressionistic critics who were most attracted to the l~nguage of the drama. Swinburne, however, occasionally transcended his fragmented approach and offered significant interpretations of Tourneur, Massinger; 'The .Changeling, Heywood. Symons's range was more limited but his form of impressionism was valuable for its concentration on the aesthetic experience at the heart of a work of art. His most important contributions were the study of Middleton and Massinger. Besides these four major critics numerous lesser writers worked on the series. Their editorial work was valuable and some, notably Ernest Rhys, c. H. Herford and Thomas Dickinson offered criticism of enduring importance. In my first chapter I consider the general availability of texts of the Elizabethan and Jacobean drama in the nineteenth century, the general attitudes towards the drama, and the critical approaches of each of the editors. The subsequent chapters are organized around the volumes of the series. I consider the climate of opinion in which each appeared, assess its critical and editorial contribution and evaluate the work of the other Mermaid editors on the dramatist included in the volume. My study shows that the concept of the Mermaid Series and the work of its editors helped to revolutionize study of the Elizabethan and Jacobean dramatists by providing good texts and by pointing the way to our present view of the plays as whole works of art.

(Table 2, Page 252) Average chemical composition of 11 manganese nodules and crust from the Pacific Ocean

The ability of the hydrated oxides of manganese and iron to adsorb ions from solution (scavenging) is considered in relation to some problems in marine geology, chemistry, and biology. In the ferruginous sediments of the Pacific Ocean, iron oxides are accompanied by titanium, cobalt, and zirconium in amounts proportional to the iron content. Similarly, copper and nickel are linearly related to the manganese content. These observations are explained on the basis of scavenging. An electrochemical theory for the formation of manganese nodules is presented. Marine sediments are classified on the basis of the geosphere in which the solid phases originate. The distribution of certain ionic species in sea water between the solid and aqueous phases is considered on the basis of scavenging and co-ordination compound theory. The concentration of minor elements by members of the marine biosphere is explained either by the direct uptake of the element or by the uptake of iron or manganese oxides with the accompanying scavenged element.

The model is based on transport theory with accounting of dispersion, gain in EDFA and saturable absorption. The predictions of gyroscopic effect are also presented for the particular laser cavity.

Police is Dead: On the Birth of Economism

Police is Dead is an historiographic analysis whose objective is to change the terms by which contemporary humanist scholarship assesses the phenomenon currently termed neoliberalism. It proceeds by building an archeology of legal thought in the United States that spans the nineteenth and twentieth centuries. My approach assumes that the decline of certain paradigms of political consciousness set historical conditions that enable the emergence of what is to follow. The particular historical form of political consciousness I seek to reintroduce to the present is what I call “police:” a counter-liberal way of understanding social relations that I claim has particular visibility within a legal archive, but that has been largely ignored by humanist theory on account of two tendencies: first, an over-valuation of liberalism as Western history’s master signifier; and second, inconsistent and selective attention to law as a cultural artifact. The first part of my dissertation reconstructs an anatomy of police through close studies of court opinions, legal treatises, and legal scholarship. I focus in particular on juridical descriptions of intimate relationality—which police configured as a public phenomenon—and slave society apologetics, which projected the notion of community as an affective and embodied structure. The second part of this dissertation demonstrates that the dissolution of police was critical to emergence of a paradigm I call economism: an originally progressive economic framework for understanding social relations that I argue developed at the nexus of law and economics at the turn of the twentieth century. Economism is a way of understanding sociality that collapses ontological distinctions between formally distinct political subjects—i.e., the state, the individual, the collective—by reducing them to the perspective of economic force. Insofar as it was taken up and reoriented by neoliberal theory, this paradigm has become a hegemonic form of political consciousness. This project concludes by encouraging a disarticulation of economism—insofar as it is a form of knowledge—from neoliberalism as its contemporary doctrinal manifestation. I suggest that this is one way progressive scholarship can think about moving forward in the development of economic knowledge, rather than desiring to move backwards to a time before the rise of neoliberalism. Disciplinarily, I aim to show that understanding the legal historiography informing our present moment is crucial to this task.
