Abstract:
Are the threshold experiences encountered between waking and sleeping similar to the liminal space between life and death? The sights, sounds, and bodily sensations experienced in the unconscious void blur the lines between the unknown and our conscious existence. Using the figure, I portray how the body might exist in these transitional moments. Through my investigations into sleep paralysis, dream states, and notions of an afterlife and the soul, I explore how we perceive the self in these altered states of consciousness.

Abstract:
The character of an urban void is defined by the built surrounding which determines the appearance and the function of the enclosed space. In modelling urban form, three major zones corresponding to this phenomenon may be distinguished: 1. Core 2. Transition Zone 3. Surrounding The transition zone contains the capacity to determine the prospective character of the framed void. It offers the possibility to intervene in the existing urban form, not by filling, but by emptying it. The void experiences a transformation from a neglected urban object to a clearly identified urban subject. This threshold towards the void serves as a mediating element between the two coexisting situations. It acts as a "coulisse" of an urban theater towards the void.

Abstract:
The objective of my thesis is to explore and re-define the relationship between threshold and urban density. Threshold is an architectural medium, which divides and bridges spaces with certain meanings. Density is the defining character of the urban condition expressed consistently at different scales: from a city to a block, to a building and to the human habitation. My design project is about an application of threshold in architectural design within the context of urban density. The efficacy of threshold is tested in both external and internal conditions: the existing condition of the site and the internal workings of the program. To test the thesis, a design of a youth hostel in Washington D.C. was undertaken. The experiment was carried out with the following hypotheses: 1) that threshold is an architectural instrument that mitigates the urban density. and 2) that threshold negotiates the territories among the inhabitants. The design experiment demonstrated the hypotheses and therefore, confirmed the relationship between threshold and urban density.

Abstract:
Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2001.
Includes bibliographical references (p. 181-189).
A threshold signature or decryption scheme is a distributed implementation of a cryptosystem, in which the secret key is secret-shared among a group of servers. These servers can then sign or decrypt messages by following a distributed protocol. The goal of a threshold scheme is to protect the secret key in a highly fault-tolerant way. Namely, the key remains secret, and correct signatures or decryptions are always computed, even if the adversary corrupts less than a fixed threshold of the participating servers. We show that threshold schemes can be constructed by putting together several simple distributed protocols that implement arithmetic operations, like multiplication or exponentiation, in a threshold setting. We exemplify this approach with two discrete-log based threshold schemes, a threshold DSS signature scheme and a threshold Cramer-Shoup cryptosystem. Our methodology leads to threshold schemes which are more efficient than those implied by general secure multi-party computation protocols. Our schemes take a constant number of communication rounds, and the computation cost per server grows by a factor linear in the number of the participating servers compared to the cost of the underlying secret-key operation. We consider three adversarial models of increasing strength. We first present distributed protocols for constructing threshold cryptosystems secure in the static adversarial model, where the players are corrupted before the protocol starts. Then, under the assumption that the servers can reliably erase their local data, we show how to modify these protocols to extend the security of threshold schemes to an adaptive adversarial model,
(cont.) where the adversary is allowed to choose which servers to corrupt during the protocol execution. Finally we show how to remove the reliable erasure assumption. All our schemes withstand optimal thresholds of a minority of malicious faults in a realistic partially-synchronous insecure-channels communication model with broadcast. Our work introduces several techniques that can be of interest to other research on secure multi-party protocols, e.g. the inconsistent player simulation technique which we use to construct efficient schemes secure in the adaptive model, and the novel primitive of a simultaneously secure encryption which provides an efficient implementation of private channels in an adaptive and erasure-free model for a wide class of multi-party protocols. We include extensions of the above results to: (1) RSA-based threshold cryptosystems; and (2) stronger adversarial models than a threshold adversary, namely to proactive and creeping adversaries, who, under certain assumptions regarding the speed and detectability of corruptions, are allowed to compromise all or almost all of the participating servers.

Abstract:
Thesis is the quest to uncover, investigate and define the inherent, personal architectural principles that drive design. The thesis project is the vehicle that gives the boundaries and construct within which the discovery process takes place. Studying the thesis project as well as studio work from previous years is the process used to uncover where the opportunities for architecture lie. The opportunities for discovery are found where forms, elements and/or materials meet, the connections. These connections are affected by the site and program, creating a unique structure for each project. The pulling apart of structure and materials to reveal what 'is,' provides the basis of these separations and connections. The separations show the individual components of the connection, allowing for clarity of structure. The place in which these components meet is the threshold. Threshold is the key to this thesis and design. There have been many theories relating to the concept of threshold that have affected my thoughts and apply to this thesis design. In historical order, Plato’s Theory of Opposites, Aristotle's Theory of Contrariety, Van Eyck's Twin Phenomenon, Venturi's Both-And, Norberg-Schulz's Intermediary Objects, and von Meiss's Threshold Theory. Each theory deals with the connection between contradictory or opposing phenomenon. It is at the threshold that these phenomenon or forces are articulated. In studying the theories and the thesis design three clear types of threshold are apparent. They are separating, mediating and transitional. For all types, the threshold is where architecture comes alive. The program and site for the thesis project gives a context in which to study architecture. The project chosen for thesis study is a Unitarian Universalist Church for the New River Valley Fellowship in Blacksburg, Virginia. The ideology of the Unitarian Universalist religion as well as the specific views of the Blacksburg congregation are important to the selection of the site, the division of the spaces, and the design of the structure. The program was set out by the congregation for the new facility recently completed. A new site was chosen in Blacksburg. The ideology of the Blacksburg congregation in combination with the program and site create boundaries for the thesis project. The design process takes them all into account, creating an inherent order and hierarchy to the building. The thesis design is affected on all levels by the need to separate and reveal the structure, to articulate the joint, and explore the "in-between realm." This investigation of threshold is interwoven into all the design explorations such as geometry, path, structure, form and construction. The resulting building, its elements and materials, create the character of the building. The experience of sequence, color, form and feel of each place.

Abstract:
From every carving and dislodged mass, there is memory left in void. As refugees, the Rohingya resettling in the United States have been displaced out of time and place. This project proposal aims to reconnect persons to place and community. Surrounded on all sides by remnant chestnut oak forest, the "rock oak" of the Appalachian, this establishment of subsidized multi-family resettlement housing, a mosque, and a Rohingya cultural center serves as the rock foundation from which to stabilize the chaos of the unknown. While memory embraces cultural identity, growth embraces new connections - defining a platform of past and future. Roof farms and open circulation plans visualize the seasons. The cropped grass field opens between the three buildings on the complex. They face each other across a green field - conversing in rows of tall oaks and stone brick colonnades in a gradient of public to private space. Children race the setting sunlight down steps and a communal dinner is served. For these wanderers, this is the threshold of refuge.

Abstract:
The sacred and the profane: a dichotomy that can only exist through the thresholds within. In a world that's drowning in the profane, we yearn for the ephemeral, in which our mind, body, and soul emerge out of the mundanity of day-to-day life, and into something beyond. We search for the art, seek pilgrimage, and long for the symbols. The physical, emotional, and sensational thresholds we pass between the two states are what resonate in our bodies. Those experiences are the stories we pass on. Yet, some of the most sacred spaces in the world have become mere subjects behind the lens of a camera. Technology has empowered our ability to reach marvels, yet it has provided layers now inherently filtered onto our experiences. How real are these thresholds we long to pass if they are experienced only through electronic devices? The sacred experiences I treasure the most were given life through movement: movement of time, light, and the elements, none of which I would trade for a photograph. The following pages trace my imagination of a place where we take a step back through the door we barely noticed. Instead of looking for the sacred, we journey through the profane. We celebrate the threshold.

Abstract:
The purpose of this investigation was to identify the intensity of recovery exercise, relevant to endurance event performance, that would result in the most rapid times for half decrease in blood lactate concentration, following 2 minutes of cycling at maximal rates. Three recovery exercise intensities were investigated: (a) 7% of the maximal rate of oxygen consumption (VO$\sb2$) (LT $-$7%), (b) lactate threshold VO$\sb2$ ( LT), and (c) 7% of VO$\sb2$max above lactate threshold VO$\sb2$ (LT +7%). Seven well-trained male cyclists (mean VO$\sb2$max 4.6 $\pm$ 0.49 L $\times$ min$\sp{-1}$ participated as subjects in the investigation. Each subject completed seven separate cycling tests: (a) one combined lactate threshold-VO$\sb2$max test, (b) three constant work rate tests, and (c) three tests of recovery following supra-lactate threshold exercise (surge-recovery tests). The absolute values of blood lactate concentration were significantly different across the three recovery intensities (p .01). At the end of the 20 minute recovery period the mean blood lactate concentrations were 1.57, 2.49, and 4.17 mmol $\times$ L$\sp{-1}$ for the LT $-$7%, LT%, and LT +7% recovery intensities, respectively. Times for half decrease in blood lactate concentration were calculated. There were no significant differences in these half decrease times between the three recovery intensities (p .01).

Full text
Abstract:
The focus of this thesis is the imposition of order onto a non-ordered space through the design of boundaries. The designed elements are derived from both the existing site conditions and the desire to improve the space, a threshold to the stadium.

A building that acts as a boundary becomes a type of wall, having two very pragmatic sides. Therefore, in this case, these elements must also function as a filter. The challenge is to design a boundary or an edge condition which defines the site, in addition to framing the views and allowing people to pass through these thresholds.

Likewise, circulation also helps to structure the site. The designed buildings allow for persons to pass along as well as to pass through. The elements placed onto the site allow for both formal and direct paths through the site, as well as more general and autonomous approaches to the stadium, located on the edge of the site.

Abstract:
In designing a sacred space, the work should be a product not only of the mechanics of the mind but also a response of the heart, and therefore the spirit or soul that an architect must possess. For the soul is the harmony between the two. This is what gets diffused into the work, the subjectivity of which gives it its reality. The work too can then become animate with soul. Mircea Eliade believed that through symbols, the world becomes transparent and transcendence becomes visible. The religious man therefore relies on symbols to recognize sacred reality. â Divine work always preserves its quality of transparency, that is it spontaneously reveals the many aspects of the sacred,â which is why the very existence of the cosmic system and everything within presents itself as a proof of divine presence.1 For the construction of a sanctuary, the goal is to be able to perceive what is sacred in the mundane, and then bringing it forth, extracting it, distinguishing it to be experienced sensually. Sacred architecture is what identifies and then exposes these hierophanies. The site is located on the intersection of Pennsylvania Ave NW and 26th ST NW in Washington DC. For the design development, the story of the first revelation of Prophet Muhammad, peace be upon him, is used as a narrative through the project. His search for meaning and retreat into nature, teaches of Islamic monasticism, the path that leads completely inward to a place with no one but God. â Every road will lead you to this sense of initiation â the light, the secret, are hidden in the place from which you set out. You are on your way not toward the end of the road but toward its beginning; to go is to return; to find is to rediscover.â 2

Full text
Abstract:
The Book of Exodus in the Old Testament recounts the liberation and salvation of an oppressed people and their subsequent journey to and arrival at the Promised Land. In the Christian Church, this journey continues in the lives of believers. The spiritual journey begins with salvation, continues with a repeated process of suffering and redemption, and terminates with an awakening to a better understanding of God.

The spiritual journey made concrete is the concern of this project. The Christian life, grossly simplified, is a passage from one place to another. The believer is constantly passing through the threshold from this life to the next, from an old, limited understanding of the divine to a new understanding.

In the Catholic Church, this process of passage is ritualized in the journey of the believer to the church each Sunday. Upon entering the church building, the believer passes from the secular and mundane to the sacred and holy.

Where does the secular end and the sacred begin? How does one delimit a boundary between the two? How does one cross the threshold from the profane to the sacred? That is the focus of this project.

Abstract:
This thesis argues that the urge to build and the adoption of a technocratic disposition have influenced and affected the pursuit and development of a deeper understanding of the discipline of computing and its pedagogy. It proposes the introduction to the discipline of the threshold concept construct to improve both the understanding and the pedagogy. The research examines the threshold concept construct using the theory of concepts. The examination establishes the conceptual coherence of the features attributed to threshold concepts and formalises the basis for threshold concept scholarship. It also provides a refutation for critiques of threshold concepts. The examination reveals the inextricable links between threshold concepts and pedagogic content knowledge. Both rely on the expertise of reflective pedagogues and are situated at the site of student learning difficulties and their encounters with troublesome knowledge. Both have deep understanding of discipline content knowledge at their centre. The two ideas are mutually supportive. A framework for identifying threshold concepts has been developed. The framework uses an elicitation instrument grounded in pedagogic content knowledge and an autoethnographic approach. The framework is used to identify state as a threshold concept in computing. The significant results of the research are two-fold. First, the identification of state as a threshold concept provides an insight into the disparate difficulties that have been persistently reported in the computer science education literature as stumbling blocks for novice programmers and enhances and develops the move towards discipline understanding and teaching for understanding. Second, the embryonic research area of threshold concept scholarship has been provided with a theoretical framework that can act as an organising principle to explicate existing research and provide a coherent focus for further research

Full text
Abstract:
This thesis is concerned with the design and development of compact, all-solid-state femtosecond pulse lasers with low pump power requirements. A number of directly-diode- pumped laser systems based on the gain materials Cr3:LiSrGaF6 (chromium-doped lithium strontium aluminium fluoride) and Cr3:LiSrGaF6 (chromium-doped lithium strontium gallium fluoride) pumped with AlGaInP laser diodes are described. The motivation behind this work was the development of portable, low-noise and lower cost ultrashort pulse lasers for a number of low-power applications such as the characterisation of electron-optical streak camera systems. The investigation into the modelocking of lasers with modest intracavity powers was also an important challenge. The achievement of a battery-powered, compact and efficient laser system represents an excellent outcome for this research programme. Major consideration is given to the key factors that determine both the cw and modelocking thresholds of an ultrashort-pulse laser. In particular, the reduction of intracavity optical losses by designing the laser to operate with fewer cavity elements, the optimisation of second-order and higher-order dispersion for efficient modelocked operation and the inclusion of a semiconductor saturable absorber mirror for increased stability are discussed. This has enabled pump thresholds to be reduced to a level permitting, for the first time, the use of diffraction-limited, narrow-stripe laser diodes for efficient, low-power optical pumping. A number of laser oscillators with novel cavity designs and progressively lower pump thresholds are described. Pulses as short as 57 fs and average output powers as high as 9 mW for only 80 mW of incident pump power are reported for a battery powered femtosecond Cr:LiSAF laser. This represents an overall electrical-to-optical conversion efficiency of approximately 1% which is excellent for a femtosecond pulse laser system. In addition, the amplitude and phase noise performance is shown to be exceptionally good and is believed to be the best yet reported for this type of ultrashort pulse laser. The design and demonstration of highly compact, ultrashort-pulse lasers incorporating novel resonator configurations and simplified dispersion compensation schemes are then described. These lasers produced sub-ps pulses at cavity frequencies as high as 450 MHz.

Sited in downtown Washington D.C. the proposed office building becomes the permeable barrier between street and lawn. Within the building there is contrasting differentiation between service space and occupiable office space through the role of different building parts that make up an office building.

Full text
Abstract:
This paper considers Bayesian estimation of the threshold vector error correction (TVECM) model in moderate to large dimensions. Using the lagged cointegrating error as a threshold variable gives rise to additional difficulties that are typically solved by relying on large sample approximations. Relying on Markov chain Monte Carlo methods we circumvent these issues by avoiding computationally prohibitive estimation strategies like the grid search. Due to the proliferation of parameters we use novel global-local shrinkage priors in the spirit of Griffin and Brown (2010). We illustrate the merits of our approach in an application to five exchange rates vis-á-vis the US dollar and assess whether a given currency is over or undervalued. Moreover, we perform a forecasting comparison to investigate whether it pays off to adopt a non-linear modeling approach relative to a set of simpler benchmark models.

Abstract:
This thesis is part of a larger series of studies being conducted by Kristine Tanner, PhD, Associate Professor in the Department of Communication Disorders at Brigham Young University (BYU). The larger project is funded by the National Institute on Deafness and Other Communication Disorders at the National Institutes of Health. This thesis primarily investigated the effects of combination inhaled corticosteroids (ICs) on aerodynamic measures of the voice. In recent years, an increase in the localized laryngeal side effects from IC treatment, including dysphonia, have been reported. This study employed a between-groups experimental design, with two groups of rabbit larynges having been exposed to either ICs or nebulized isotonic saline two times each day for eight weeks at The University of Utah. For this study, the independent variable is group condition (i.e., IC versus saline) and the dependent variables are two aerodynamic measurements made at the onset of phonation using a benchtop experimental setup, namely phonation threshold pressure (PTP; cmH2O) and phonation threshold flow (PTF; L/min). The results of this study indicate a significant difference in PTP and PTF between vocal folds treated with IC as compared to vocal folds treated with nebulized isotonic saline solution. Implications of this study suggest negative changes in the voice due to IC treatment.

Abstract:
We investigate the complexity of computations with constant-depth threshold circuits. Such circuits are composed of gates that determine if the sum of their inputs is greater than a certain threshold. When restricted to polynomial size, these circuits compute exactly the functions in the class TC$ sp0$.
These circuits are usually studied by measuring their efficiency in terms of their total depth. Using this point of view, the best division and iterated multiplication circuits have depth three and four, respectively.
In this thesis, we propose a different approach. Since threshold gates are much more powerful than AND-OR gates, we allow the explicit use of AND-OR gates and consider the main measure of complexity to be the majority-depth of the circuit, i.e. the maximum number of threshold gates on any path in the circuit. Using this approach, we obtain division and iterated multiplication circuits of total depth four and five, but of majority-depth two and three.
The technique used is called Chinese remaindering. We present this technique as a general tool for computing functions with integer values and use it to obtain depth-four threshold circuits of majority-depth two for other arithmetic problems such as the logarithm and power series approximation. We also consider the iterated multiplication problem for integers modulo q and for finite fields.
The notion of majority-depth naturally leads to a hierarchy of subclasses of TC$ sp0$. We investigate this hierarchy and show that it is closely related to the usual depth hierarchy.

Abstract:
The following thesis is a meditation on the drawings of Michelangelo that are connected to his three projects at San Lorenzo and a series of 'gift' drawings for Tomasso de'Cavalieri. The drawings offer a glimpse of his radically inventive imagination that calls for an architecture rooted in the soul and based on the appearance of a 'live' and an emotive body. Engaged within a holistic fabrication of architecture, both the recto and the verso of the sheet are constructed as palimpsests comprised of design sketches, figurative studies, poetic fragments and pragmatic calculations. As instruments of communication, Michelangelo's paper templates are intermediaries between the 'Divine One's' mindful hand and the scarpellini's chisel. A line can be traced from the outline of his disegno , the profillo of a face and the cut line of his modani. Poetry and profiles cross-pollinate in a poiesis of architecture that culminates at a threshold---the hinge between being and becoming---the place where Love tosses in his sleep.

A nuclear threshold state is one that could quickly operationalize its peaceful nuclear program into one capable of producing a nuclear weapon. This thesis compares two known threshold states, Japan and Brazil, with Iran to determine if the Islamic Republic could also be labeled a threshold state. Furthermore, it highlights the implications such a status could have on U.S. nonproliferation policy. Although Iran's nuclear program is mired in controversy, it relates to those of Japan and Brazil. While not maintaining as robust of a program and often conflicting with the international community, Iran has the capabilities to produce weapons grade material and could be considered a nuclear threshold state. Dozens of countries in the world have similar nuclear capabilities and maintain the Nuclear Non-Proliferation Treaty rights to advance their nuclear programs so long as they are peacefully applied. Unfortunately for nonproliferation advocates, these capabilities make fuel for both energy and weapons. To prevent proliferation and eliminate the world’s nuclear weapons arsenal, the United States will need to alter its policy and convince the world that nuclear weapons should be abolished. Although this task includes a multitude of variables, incremental steps can be taken toward the administration’s final goal.

Abstract:
"The process of securing data has always been a challenge since it is related to the safety of people and society. Nowadays, there are many cryptographic algorithms developed to solve security problems. However, some applications have constraints which make it difficult to achieve high levels of security. Light weight cryptography aims to address this issue while trying to maintain low costs. Side-channel attacks have changed the way of cryptography significantly. In this kind of attacks, the attacker has physical access to the crypto-system and can extract the sensitive data by monitoring and measuring the side-channels such as power consumption, electromagnetic emanation, timing information, sound, etc. These attacks are based on the relationship between side-channels and secret data. Therefore, there need to be countermeasures to eliminate or reduce side channel leaks or to break the relationship between side-channels and secret data to protect the crypto systems against side-channel attacks. In this work, we explore the practicality of Threshold Implementation (TI) with only two shares for a smaller design that needs less randomness but is still leakage resistant. We demonstrate the first two-share Threshold Implementations of light-weight block cipher Present. Based on implementation results, two-share TI has a lower area overhead and better throughput when compared with a first-order resistant three-share scheme. Leakage analysis of the developed implementations reveals that two-share TI can retain perfect first-order resistance. However, the analysis also exposes a strong second-order leakage. "

We study a model for cascade effects over finite networks based on a deterministic binary linear threshold model. Our starting point is a networked coordination game where each agent's payoff is the sum of the payoffs coming from pairwise interaction with each of the neighbors. We first establish that the best response dynamics in this networked game is equivalent to the linear threshold dynamics with heterogeneous thresholds over the agents. While the previous literature has studied such linear threshold models under the assumption that each agent may change actions at most once, a study of best response dynamics in such networked games necessitates an analysis that allows for multiple switches in actions. In this thesis, we develop such an analysis and construct a combinatorial framework to understand the behavior of the model. To this end, we establish that the agents behavior cycles among different actions in the limit and provide three sets of results. We first characterize the limiting behavioral properties of the dynamics. We determine the length of the limit cycles and reveal bounds on the time steps required to reach such cycles for different network structures. We then study the complexity of decision/counting problems that arise within the context. Specifically, we consider the tractability of counting the number of limit cycles and fixed-points, and deciding the reachability of action profiles. We finally propose a measure of network resilience that captures the nature of the involved dynamics. We prove bounds and investigate the resilience of different network structures under this measure.

Abstract:
In this thesis we implement estimating procedures in order to estimate threshold parameters for the continuous time threshold models driven by stochastic di®erential equations. The ¯rst procedure is based on the EM (expectation-maximization) algorithm applied to the threshold model built from the Brownian motion with drift process. The second procedure mimics one of the fundamental ideas in the estimation of the thresholds in time series context, that is, conditional least squares estimation. We implement this procedure not only for the threshold model built from the Brownian motion with drift process but also for more generic models as the ones built from the geometric Brownian motion or the Ornstein-Uhlenbeck process. Both procedures are implemented for simu- lated data and the least squares estimation procedure is also implemented for real data of daily prices from a set of international funds. The ¯rst fund is the PF-European Sus- tainable Equities-R fund from the Pictet Funds company and the second is the Parvest Europe Dynamic Growth fund from the BNP Paribas company. The data for both funds are daily prices from the year 2004. The last fund to be considered is the Converging Europe Bond fund from the Schroder company and the data are daily prices from the year 2005.
