Factors In Mobile Game Design, Robert Mccloud

Robert McCloud

Mobile is the fastest growing area for computer gaming. Fueled by the every growing sales of handheld devices, the increasing comfort of gamers with their devices, larger screens and availability of casual games, mobile games offer the developer an area of rapid growth. In this paper we report on the commencement of research that attempts to identify the key development concepts for a mobile game. Gamers’ locus of controlis examined to determine the extent to which this personality trait impacts both interest level and type of game. We consider two mobile games, Grand Theft Auto and Edge, in an attempt …

Sampling For Complexity In Rendering, Jiawei Ou

Dartmouth College Ph.D Dissertations

As the visual effect and movie industries are striving for realism and high fidelity images, physically based lighting, global illumination, realistic materials, and highly tessellated geometry are gradually accepted and used in movie and game industries. Modern computer graphics has reached an unprecedented level of complexity. As a result, brute-force rendering methods become prohibitively expensive. For decades, computer graphics researchers have been tackling the complexity in rendering by introducing more advanced Monte Carlo integrators, efficient sampling and reconstruction algorithms, effective filtering techniques, sophisticated data structures, and new hardware architectures. In this thesis, we focus on deriving better sampling algorithms to …

Damage Detection And Mitigation In Open Collaboration Applications, Andrew G. West

Andrew G. West

Collaborative functionality is changing the way information is amassed, refined, and disseminated in online environments. A subclass of these systems characterized by "open collaboration" uniquely allow participants to modify content with low barriers-to-entry. A prominent example and our case study, English Wikipedia, exemplifies the vulnerabilities: 7%+ of its edits are blatantly unconstructive. Our measurement studies show this damage manifests in novel socio-technical forms, limiting the effectiveness of computational detection strategies from related domains. In turn this has made much mitigation the responsibility of a poorly organized and ill-routed human workforce. We aim to improve all facets of this incident response …

Contradictions In Improving Speed Of Virus Scanning, Umakant Mishra

Umakant Mishra

Although everything in computing industry moves faster, the processor, memory speed, memory size, storage space etc. there is no improvement in virus scanning time. Although the processing speed has substantially increased, a typical full scanning is still taking several hours for an average computer. There is a serious need to improve the scanning time.

Contradiction is a stage of problem solving where the nature of the actual problem is clearly explained in terms of at least two parameters, one improving and another worsening. While emphasizing one parameter strengthens the system position emphasizing another parameter weakens the system.

In conventional methods …

Finding And Solving Contradictions Of False Positives In Virus Scanning, Umakant Mishra

Umakant Mishra

False positives are equally dangerous as false negatives. Ideally the false positive rate should remain 0 or very close to 0. Even a slightest increase in false positive rate is considered as undesirable.

Although the specific methods provide very accurate scanning by comparing viruses with their exact signatures, they fail to detect the new and unknown viruses. On the other hand the generic methods can detect even new viruses without using virus signatures. But these methods are more likely to generate false positives. There is a positive correlation between the capability to detect new and unknown viruses and false positive …

Methods Of Repairing Virus Infected Files, A Triz Based Analysis, Umakant Mishra

Umakant Mishra

Some computer viruses damage the host file during infection either partially or fully. These types of viruses are known as “file modifying viruses”. In these cases, the chance of recovery is less, but the anti-virus has to apply various methods with hope. The virus cleaner must know the characteristics of a virus in order to remove that virus. It cannot remove an unknown virus whose methods of infection are not known. If a virus is wrongly detected to be a different virus, then the cleaner will do wrong operations and build a garbage file.

Most viruses are capable of fixing …

Balance Or Trade-Off? Online Security Technologies And Fundamental Rights, Mireille Hildebrandt

Mireille Hildebrandt

In this contribution I argue that the image of the balance is often used to defend the idea of a trade-off. To understand the drawbacks of this line of thought I will explore the relationship between online security technologies and fundamental rights, notably privacy, non-discrimination, freedom of speech and due process. After discriminating between three types of online security technologies I will trace the reconfiguration of the notion of privacy in the era of smart environments. This will lead to an inquiry into the metaphor of the scale, building on the triple test regarding the justification of the limitation of …

Towards A Physically Meaningful Definition Of Computable Discontinuous And Multi-Valued Functions (Constraints), Martine Ceberio, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In computable mathematics, there are known definitions of computable numbers, computable metric spaces, computable compact sets, and computable functions. A traditional definition of a computable function, however, covers only continuous functions. In many applications (e.g., in phase transitions), physical phenomena are described by discontinuous or multi-valued functions (a.k.a. constraints). In this paper, we provide a physics-motivated definition of computable discontinuous and multi-valued functions, and we analyze properties of this definition.

Using Symmetries (Beyond Geometric Symmetries) In Chemical Computations: Computing Parameters Of Multiple Binding Sites, Andres Ortiz, Vladik Kreinovich

Departmental Technical Reports (CS)

We show how group-theoretic ideas can be naturally used to generate efficient algorithms for scientific computations. The general group-theoretic approach is illustrated on the example of determining, from the experimental data, the dissociation constants related to multiple binding sites. We also explain how the general group-theoretic approach is related to the standard (backpropagation) neural networks; this relation justifies the potential universal applicability of the group-theoretic approach.

Processing Quantities With Heavy-Tailed Distribution Of Measurement Uncertainty: How To Estimate The Tails Of The Results Of Data Processing, Michal Holčapek, Vladik Kreinovich

Departmental Technical Reports (CS)

Measurements are never absolutely accurate; so, it is important to estimate how the measurement uncertainty affects the result of data processing. Traditionally, this problem is solved under the assumption that the probability distributions of measurement errors are normal -- or at least are concentrated, with high certainty, on a reasonably small interval. In practice, the distribution of measurement errors is sometimes heavy-tailed, when very large values have a reasonable probability. In this paper, we analyze the corresponding problem of estimating the tail of the result of data processing in such situations.

Interpreting And Reconstructing Data From Sensor Networks, Jonathan H. Guinther

Computer Science Technical Reports

Geophysical phenomena are often three-dimensional, time-variant, and physically large, making them difficult to measure. As wireless sensor nodes become cheaper, smaller, and more powerful, using a sensor swarm as a sampling framework seems to be a viable approach to this problem. However, samples from the network can be sparse and unstructured, creating an incomplete picture. Thus, the question addressed by this project is the following: How can we easily construct and interpret the best model of the underlying reality over some domain, given a possibly sparse and irregular set of samples? We present the design, implementation, and evaluation of the …

Geometrical And Probabilistic Methods For Determining Association Models And Structures Of Protein Complexes, Himanshu Chandola

Dartmouth College Ph.D Dissertations

Protein complexes play vital roles in cellular processes within living organisms. They are formed by interactions between either different proteins (hetero-oligomers) or identical proteins (homo-oligomers). In order to understand the functions of the complexes, it is important to know the manner in which they are assembled from the component subunits and their three dimensional structure. This thesis addresses both of these questions by developing geometrical and probabilistic methods for analyzing data from two complementary experiment types: Small Angle Scattering (SAS) and Nuclear Magnetic Resonance (NMR) spectroscopy. Data from an SAS experiment is a set of scattering intensities that can give …

An Ontology Design Pattern For Cartographic Map Scaling, David Carral, Simon Scheider, Krzysztof Janowicz, Charles Vardeman Ii, Adila A. Krisnadhi, Pascal Hitzler

Computer Science and Engineering Faculty Publications

The concepts of scale is at the core of cartographic abstraction and mapping. It defines which geographic phenomena should be displayed, which type of geometry and map symbol to use, which measures can be taken, as well as the degree to which features need to be exaggerated or spatially displaced. In this work, we present an ontology design pattern for map scaling using the Web Ontology Language (OWL) within a particular extension of the OWL RL profile. We explain how it can be used to describe scaling applications, to reason over scale levels, and geometric representations. We propose an axiomatization …

The Role Of String Similarity Metrics In Ontology Alignment, Michelle Cheatham, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Tim Berners-Lee originally envisioned a much different world wide web than the one we have today - one that computers as well as humans could search for the information they need [3]. There are currently a wide variety of research efforts towards achieving this goal, one of which is ontology alignment.

Biomarkers Of Fatigue: Metabolomics Profiles Predictive Of Cognitive Performance, Nicholas J. Delraso, Deirdre A. Mahle, John J. Schlager, Donald L. Harville, Scott R. Chaiken, Danelle K. Roddy, Mari Chamberlain, Paul E. Anderson, Nicholas V. Reo, Michael L. Raymer, Isaie Sibomana

Computer Science and Engineering Faculty Publications

Cognitive performance and fatigue are well known to be inversely related. Continuous and sustained actions in operational environments typically lead to reduced sleep normally required to perform optimally. These operational environments subject the warfighter to intense physical and mental exertion. Because fatigue continues to be an occupational hazard, leading to cognitive defects in performance, there has been a recognized need for real-time detection technologies that minimize fatigue-induced mishaps. I the current study, 23 subjects were subjected to 36h of sleep deprivation and cognitive psychomotor vigilance and automated neuropsychological assessment metric tests were conducted over the last 24 h of sleep …

There's No Money In Linked Data, Prateek Jain, Pascal Hitzler, Krzysztof Janowicz, Chitra Venkatramani

Computer Science and Engineering Faculty Publications

Linked Data (LD) has been an active research area for more than 6 years and many aspects about publishing, retrieving, linking, and cleaning Linked Data have been investigated. There seems to be a broad and general agreement that in principle LD datasets can be very useful for solving a wide variety of problems ranging from practical industrial analytics to highly specific research problems. Having these notions in mind, we started exploring the use of notable LD datasets such as DBpedia, Freebase, Geonames and others for a commercial application. However, it turns out that using these datasets in realistic settings is …

Download Question And Section Results Output For Inettest System, Pradeep Jagannath Rohokale

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

iNetTest is a useful tool to help instructors deliver computer-based tests, but when an instructor gives a test, they would often like to know individual question results, e.g.

• What was the average score for a question, how many got it correct and how many missed it,
• What was the most common answer chosen (for multiple choice, T/F, etc.),
• What was the score for a section?
• What was the average score for a section?
• etc.

Whenever individuals consider such data they often prefer different or multiple ways in which to analyze the data. For that reason, it was decided not to …
