Full textI föreliggande studie undersöktes hur Tidsperspektiv (TP), d.v.s. kognitivt inordnande av mänskliga erfarenher i tidsmässiga dimensioner, och Tidmässigt Avstånd (TA), d.v.s. upplevd närhet av händelser i tid, påverkar moralisk bedömning. Studien omfattade 132 deltagare, vilka fyllde i den svenska versionen av Zimbardo Time Perspective Inventory (S-ZTPI) och gjorde moraliska bedömningar av överträdelser av etiska regler framställda i en nära vs. avlägsen framtid. En huvudeffekt av TP framkom, vilken innebar att överträdelse av etiska regler bedömdes som mer omoraliskt utifrån Positiv-Dåtidsorientering och Framtidsorientering jämfört med Hedonistisk-Nutidsorientering och Negativ-Dåtidsorientering. Ingen huvudeffekt av TA framkom. Interaktionen mellan TP och TA var signifikant och i linje med prediktionerna även om endast Hedonistisk-Nutidsorientering påverkades signifikant av TA: tidsmässigt avlägsna vs. närliggande scenarion bedömdes som mindre omoraliska utifrån detta TP. Vikten av studien samt begränsningar och tänkbara uppföljningar av studien diskuteras också.

Full textImaging through turbid media like fog, tissues, colloids etc. has various applications in real-life situations. The problem of imaging through such scattering media presents a challenge that can be addressed by using novel imaging schemes, information theory and laws of light transport through random scattering media. The thesis is divided into two parts corresponding to two different imaging modalities, namely, polarimetric contrast imaging and intensity modulated light imaging. In both the cases, advanced imaging systems, capable of imaging in real-time are used and their performances are evaluated both theoretically and experimentally. In the first part of the thesis, a two-channel, snapshot polarimetric camera, based on a Wollaston prism is used to attain optimal imaging of polarized light source through fog. An original outdoor experiment is setup in the vicinity of the campus Beaulieu in Rennes, France, where a source is placed on a telecommunication tower more than a kilometer away from the imaging system. Data acquired in various weather conditions show that the efficiency of the two-channel polarimetric camera depends on the background noise correlation in the two images. Further, this was confirmed using an information theoretical analysis, which showed that a polarimetric contrast maximizing image representation is a linear combination of the two polarimetric images whose weights depend on the background noise correlation. Based on the derived optimal polarimetric representation, a detection scheme was presented, leading to an end-to-end study of two-channel polarimetric imaging through fog that may be useful in transport applications like aircraft landing/taxiing in degraded weather. The second part of the thesis deals with intensity modulated light and its potential for ballistic photon imaging through scattering media. First, using the diffusion theory of photon transport and information theory, it was shown that for a given photon budget, ballistic imaging can be achieved for a minimum modulation frequency that depends on the scattering properties of the intervening medium. In real-life situation, the minimum frequency can be in the range of MHz. Real-time imaging at these frequencies is a challenge. Hence, a novel demodulation camera system based on electro-optics was proposed and patented. The imaging system is capable of real-time, full-field demodulation at frequencies of several MHz (potentially, in GHz as well), without requiring a phase synchronized source. A prototype of the imaging system was developed and shown that a demodulation camera based on the proposed design is robust, portable and cost-effective. Finally, the work presented in this thesis pave way for implementation of advanced imaging systems in real-life situations, varying from biomedical imaging to transport safety
Mattar, Andrew. "Generalization of dynamics learning across direction, distance and time." Thesis, McGill University, 2010. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=86872.
Full textFollowing a General Introduction in Chapter 1, in Chapter 2 we examine whether having learned to move in multiple directions affects the extent of generalization. In Chapter 3, we examine generalization of dynamics learning across changes in movement amplitude. In Chapter 4, we note that generalization of learning does not depend only on the separation between training and test directions, as was shown in Chapter 2. In addition, generalization depends on the extent of learning during training. We examine the effect of impedance - a mechanical property of the arm under neural control - on dynamics learning and generalization. In Chapter 5, we examine generalization of dynamics learning over time. Overall, our findings suggest that dynamics learning is a process involving local adaptation of the neural control signals for movement, and that interpolation between these instances of local learning is possible. These findings suggest that the apparent ease with which humans move in new situations may depend on interpolation between instances of previous learning that were acquired in a range of nearby situations. We elaborate on this idea in a General Discussion in Chapter 6.
La capacité de l'être humain à adapter ses mouvements à une grande variété de situations témoigne de la grande plasticité du contrôle neuronal du mouvement. Cette plasticité peut s'étudier via l'apprentissage dynamique qui correspond au processus par lequel le système nerveux met en place les signaux neuronaux nécessaires à la production des forces qui génèrent le mouvement. La présente thèse reporte une série d'expériences étudiant l'apprentissage dynamique et sa généralisation. Dans ces expériences, l'apprentissage dynamique est obtenu en amenant le sujet à compenser une perturbation mécanique systématiquement appliquée sur le bras par un robot au cours de l'exécution d'un mouvement d'atteinte de cible. Plus particulièrement, nos études sont centrées sur deux propriétés importantes de l'apprentissage dynamique: (1) le fait que l'apprentissage dynamique impliquerait des instances d'adaptation locales et (2) le fait que la généralisation de cet apprentissage se fonderait sur une interpolation entre ces instances d'adaptation locales.
Après une introduction générale dans le Chapitre 1, le Chapitre 2 examine si l'étendue de la généralisation de l'apprentissage dynamique dépend de l'étendue des situations rencontrées lors de la phase d'apprentissage. Le Chapitre 3 est consacré à l'étude de la généralisation de l'apprentissage dynamique à des mouvements de différentes amplitudes. Au Chapitre 4, nous montrons ensuite que la généralisation de l'apprentissage ne relève pas seulement de ces aspects méthodologiques. Comme le rapporte le Chapitre 2, la généralisation dépend aussi de l'étendue de l'apprentissage, elle-même liée aux propriétés biomécaniques des effecteurs. Le Chapitre 5 est consacré à l'évolution de la généralisation de l'apprentissage dynamique au cours du temps. L'ensemble de nos travaux suggère que l'apprentissage dynamique est un processus impliquant une adaptation locale des signaux du contrôle neuronal du mouvement et que l'interpolation de ces instances d'apprentissage local est possible. Ainsi, comme nous le discutons au Chapitre 6, l'apparente facilité de l'être humain à adapter ses mouvements à des situations nouvelles pourrait en réalité être le fruit de l'interpolation entre les instances d'apprentissages antérieurs acquis dans une gamme de situations similaires.

Full textThis study examined if social distance, i.e. in- vs. out-group membership, had an effect on moral judgments of acts vs. omissions. 164 participants judged the morality of acts vs. omissions of lethal harm, that affected an in- vs. out-group member of the participant, in order to save five other people. The results showed that acts of lethal, but utilitarian, harm were judged more immoral than omissions of equivalent harm. It was also shown that if the victim was an in- group member of the participant the behavior was judged more immoral than if the victim was an out-group member of the participant. However, the acts and omissions of harm were not judged differently when the victim was an in.- vs. out-group member of the participant, indicating that this kind of social distance might not influence the moral judgment of acts and omissions.
Borrego, Dulce Armonía. "Value Equivalency Analysis: Quantity Compensation, Distance Decay, And Time Treatment." Doctoral thesis, Universitat Autònoma de Barcelona, 2011. http://hdl.handle.net/10803/42010.
Full textEnvironmental compensation implies the provision of additional natural resources, services or social welfare through restoration projects that are scaled to equal the losses due to environmental damage. The Environmental Liability Directive provides legal framework in the European Union for introducing environmental liability due to damages to the environment caused by industrial operators. Environmental liability requires that harmed natural resources be restored to baseline conditions (primary restoration) and compensated for the accumulated losses (interim losses) produced from the time of the incident until the environment reaches baseline conditions (compensatory restoration). Equivalency Analysis is a methodology used to determine compensation for environmental damage. This study uses an Equivalency Analysis (EA) approach namely the value-to-value approach as a tool to scale remediation and to estimate the amount of compensatory restoration to off-set an environmental damage following a wild forest fire in the northeast of Spain. Value Equivalency Analysis (VEA) is undertaken by a Contingent Valuation (CV) exercise to determine the welfare loss from the initial damage and interim loss and then a remediation project that can be established based on that information. The study elicits the minimum amount of compensation required to make individuals as well off as they would be in the baseline situation. After this the study explores remediation located at a geographical distance from the site of damage. In some cases displacement between damaged resources and restored resources is allowed, this study explores whether longer distance from the damaged site could imply a larger amount of compensation to offset the change in natural resource location. For this, an additional exercise was designed to estimate the trade-off rate for compensating in a farther away site using choice experiment techniques. Finally, the last section focuses on the information provided to respondents regarding payments in the survey instrument. This includes informing respondents how they would pay for the restoration program and whether payments correspond to nominal or real values. The survey instrument takes the form of a single bounded dichotomous choice where the payments are to be made every year over a ten year period and they would go up every year according to inflation.

Minteer, Timothy Michael. "Electromagnetic modeling based on directional time-distance energy transfer analogies." Thesis, Washington State University, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=3587146.
Full textA new electromagnetic model is established based on an average rate of directional time-distance energy transfers. A directional time-distance energy transfer is defined as an energy carrier mediator (boson) exchange. Electromagnetic force is modeled as mean valued, continual emission and absorption of energy carrier mediators.
For an isolated, spherically symmetric static charge distribution, Maxwell's stress equation is recast using a variant of Stokes' Theorem. The recast stress equation eliminates the stress normal to the electric field and establishes a stress only aligned with the electric field. The remaining stress is identified as an external omnidirectional Poincaré stress, inwardly directed towards the charge distribution. The Poincaré stress is modeled as a mean valued, continual exchange of bosons between the charge distribution and the distant matter of the universe.
For two separated, spherically symmetric static charge distributions, Maxwell's stress equation is recast using a variant of Stokes' Theorem. The recast stress equation develops a line stress that only exists on the straight path between the two charge distributions. The line stress is identified as a Coulomb stress modeled as a mean valued, continual exchange of photons back and forth between two like-charge distributions.
For an isolated, differential current element, Maxwell's stress equation is recast using a variant of Stokes' Theorem. The recast stress equation establishes a pinch stress that is normal to the magnetic field and is directed inward toward the differential current element. Similar to the Poincaré stress, the pinch stress is omnidirectional and is modeled as a mean valued, continual exchange of bosons between the current element and the distant matter of the universe.
For two separated, static differential current elements, a Neumann stress is established by analyzing the historical current force formulas known to be compatible with Maxwell's equations for closed circuits. The term Neumann stress is assigned to the line stress that only exists at each point on the straight path between two separated, differential current elements. Similar to the Coulomb stress, the Neumann stress is modeled as a mean valued, continual exchange of photons back and forth between two differential current elements in opposite directions.

Full textEpisodic memory, the ability to store and later recall individual experiences, plays a fundamental role in our day-to-day lives1 and reflects a temporal organization of events that form an experience. Numerous studies have shown that the hippocampus plays a crucial role in episodic memory. Recent studies have reported the existence of hippocampal "time cells", neurons that fire at particular moments during temporally extended periods when behavior and location are relatively constant. However, the origin of these hippocampal firing patterns, and the extent to which they are primarily determined by time, or instead by variations in behavior, location, or distance traveled over time, remains uncertain. Here we introduce a novel behavioral paradigm that allowed us to investigate firing patterns in the hippocampus and medial entorhinal cortex (MEC) as rats ran in place on a treadmill, thus "clamping" behavior and location while varying treadmill speed to distinguish time and distance traveled. We recorded activity in dorsal hippocampal CA1 and showed that "time cells" exist in this task and that their firing could not be explained by movement through space alone. Instead, we found that hippocampal neurons were heavily influenced by both time and distance, with different neurons reflecting these parameters to varying extents. These findings demonstrated that hippocampal neuronal networks capture the organization of time and distance in situations where these dimensions dominate an ongoing experience. We next recorded neural activity in the MEC a dominant source of input into the hippocampus, to determine whether the MEC is also involved in temporal processing. We found many MEC neurons exhibiting temporally-modulated firing that could not be explained by either movement through space or changes in head direction. This included neurons with single and multiple temporal firing fields, as well as neurons exhibiting temporally-periodic firing during treadmill running. In addition, we found that neurons classified as grid cells during open-field foraging often fired with one or more temporal firing fields during treadmill running. Together, these findings suggest that both hippocampal and MEC neurons code for temporal, as well as spatial and other environmental regularities.

Full textTidigare forskning om mänskligt beslutsfattande och bedömningar har i experiment påvisat systematiska och förutsägbara bias. Ett exempel på detta är tendensen att intuitivt gå emot konjuktionsregeln- en enkel regel gällande sannolikhet. Detta illustrerades väl i det berömda Linda- problemet (Tversky & Kahneman, 1983). Enligt två-systemsteorin (Kahneman, 2011) om problemlösning, uppstår bedömningsfel såsom konjuktionsfelet när människor inte använder sig av analytiskt tänkande och istället förlitar sig för mycket på sin intuition. Två-systemsteorin menar att de kognitiva processer som ligger till grund för våra intuitiva impulser och vårt medvetna resonerande utgör två olika aktörer i vårt tänkande- system 1 och system 2- och att det intuitiva system 1 inte kan beräkna sannolikheter. Processer som betecknas som tillhörande system 1 är enligt två-systemsteorin snabba medan system 2 föreställs vara ett långsamt system. I denna studie testades antagandet om tidsåtgång för de två systemen i en inomgruppsdesign genom att jämföra responstider mellan bedömningar där konjunktionsfelet begåtts och bedömningar där det inte begåtts. Resultaten visar att korrekta sannolikhetsbedömningar inte resulterar i långsammare responstider. Detta indikerar att det inte tycks vara mer tidskrävande att göra riktiga sannolikhetsbedömningar, vilket motsäger två-systemsteorins antagande om snabbt och långsamt processande.

Full textIt was found that the rules that correlated most highly with network responses during training were consistent with the developmental course of children's concepts (Wilkening, 1981; 1982). Networks integrated the defining dimensions of the concepts first by identity rules (e.g., v = d), then additive rules (e.g., v = d-t), and finally multiplicative rules (e.g., v = d $ div$ t).
The results are discussed in terms of similarity to children's development, the effects of memory demands, the contribution of connectionism to cognitive development, and directions for future research. It is argued that cascade-correlation provides an explicit mechanism of developmental change--weight adjustment and hidden unit recruitment.

With the advent of "smart" consumer electronics, distance sensing is an increasingly important field in optical sensing. A novel approach to active infrared(IR) 1D distance sensing is proposed, employing both intensity and time-of-flight information. Conventional intensity based sensors lack in distance accuracy, and conventional time-of- flight sensors suffer from crosstalk and backscatter issues. The purpose of this work is to explore the solution space to these issues that hybrid intensity/time-of-flight systems enable, and to investigate their characteristics. Optical behavior of time-of-flight and intensity of an active IR system is analyzed, and a comprehensive reflection model is created. This model is then applied to describe discrete objects, and a parameterized object model is developed. Techniques such as the use of differentiated signals, least square estimation, and optimization algorithms are introduced and applied to the object model. A range of techniques based on specific use cases are developed, and their capabilities and limitations are discussed. Results show that in a limited set of conditions, combining time-of-flight and intensity information can allow the extraction of distance in conditions that are typically unfavorable for conventional methods, such as high crosstalk or high backscatter environments. Used in the right conditions, these techniques can gain immunity to these sources of error, at the cost of higher computational complexity.

Full textDispersal is an important factor in animal ecology. Anurans (frogs and toads) are often philopatric (home loving) but some specimens in a population usually have the capacity to disperse relatively long distances. In this study I investigated the colonization of newly constructed ponds in the southwest of Sweden by three anuran species: The common toad (Bufo bufo), the moor frog (Rana arvalis) and the common frog (Rana temporaria). The ponds were constructed between two and five years ago and were now as frequently occupied as older source ponds in the area. For the common toad and the common frog there was no correlation between distance to source populations and degree of colonization. The moor frog was more common in ponds that were situated in the vicinity of older source ponds with ample populations. The main impression was that these species rapidly colonize newly constructed ponds, at least within moderate distances from source populations. There were some differences between the species though and it seems like the moor frog have more limited dispersal abilities than the other two species.

In this thesis, we present methods in representation learning for time series in two areas: metric learning and risk stratification. We focus on metric learning due to the importance of computing distances between examples in learning algorithms and present Jiffy, a simple and scalable distance metric learning method for multivariate time series. Our approach is to reframe the task as a representation learning problem -- rather than design an elaborate distance function, we use a CNN to learn an embedding such that the Euclidean distance is effective. Experiments on a diverse set of multivariate time series datasets show that our approach consistently outperforms existing methods. We then focus on risk stratification because of its clinical importance in identifying patients at high risk for an adverse outcome. We use segments of a patient's ECG signal to predict that patient's risk of cardiovascular death within 90 days. In contrast to other work, we work directly with the raw ECG signal to learn a representation with predictive power. Our method produces a risk metric for cardiovascular death with state-of-the-art performance when compared to methods that rely on expert-designed representations.
