Evolutionary dynamics for the generalized Baliga–Maskin public good model
Get PDFThe problem of the consumption or provision of common and public goods is a well known and well studied problem in economic sciences. The nature of the problem is the existence of non-excludable externalities which gives rise to incentives to free-riding behaviour. There are several economical frameworks trying to deal with the problem such as coalition theory or mechanism design and implementation theory to ensure a Pareto efficient consumption or provision of such good. Baliga and Maskin considered an environmental game where several communities face a problem of pollution reduction. They show that all communities except one of them have incentives to act as a free-rider, i.e. only one community is willing to face the costs that air cleaning implies, namely the one with greatest preference for the good. In this work we introduce an adaptive evolutionary dynamics for the generalization of the Baliga–Maskin model to quasi-linear utility functions. We show that the Baliga–Maskin equilibrium is the only asymptotically stable dynamical equilibrium, all others being unstable. This result reasserts the problem of free-riding and externalities for the case of a common good in a dynamically/evolutionary setting, and reiterates the relevance of mechanism design and coalition formation in the context of dynamical models. © 201
Automated detection and containment of stealth attacks on the operating system kernel
No full textThe operating system kernel serves as the root of trust for all applications running on the computer system. A compromised system can be exploited by remote attackers stealthily, such as exfiltration of sensitive information, wasteful usage of the system's resources, or involving the system in malicious activities without the user's knowledge or permission. The lack of appropriate detection tools allows such systems to stealthily lie within the attackers realm for indefinite periods of time. Stealth attacks on the kernel are carried out by malware commonly known as rootkits. The goal of the rootkit is to conceal the presence of the attacker on the victim system. Conventionally, kernel rootkits modified the kernel to achieve stealth, while most functionality was provided by accompanying user space programs. The newer kernel rootkits achieve the malice and stealth solely by modifying kernel data. This dissertation explores the threat posed by both types of kernel rootkits and proposes novel automated techniques for their detection and containment. Our first contribution is an automated containment technique built using the virtualization architecture. This technique counters the ongoing damage done to the system by the conventional kernel rootkits. It is well suited for attacks that employ kernel or user mode stealth but provide most of the malicious functionality as user space programs. Our second contribution is to identify a new class of stealth attacks on the kernel, which do not exhibit explicit hiding behavior but are stealthy by design. They achieve their malicious objectives by solely modifying data within the kernel. These attacks demonstrate that the threat posed to kernel data is systemic requiring comprehensive protection.
Our final contribution is a novel automated technique that can be used for detection of such stealth data-centric attacks. The key idea behind this technique is to automatically identify and extract invariants exhibited by kernel data structures during a training phase. These invariants are used as specifications of data structure integrity and are enforced during runtime. Our technique could successfully detect all rootkits that were publicly available. It could also detect more recent stealth attacks developed by us or proposed by
other recent research literature.Ph.D.Includes bibliographical references (p. 99-103)by Arati Balig
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Data and code for: Hummingbirds use distinct control strategies for forward and hovering flight
No full textData and code for: "Hummingbirds use distinct control strategies for forward and hovering flight" by Baliga VB, Dakin R, Wylie DR, and Altshuler DL; Proceedings of the Royal Society B: Biological SciencesQuestions/concerns/comments: Vikram Baliga ([email protected])Data:- All data required to re-create analyses and figures are stored within /processed_data_exports. Note that these are not original (Flydra) data; due to file size constraints, Flydra data cannot be included here.- The /lookup_and_metadata directory contains several files that describe the metadata and other important characteristics of the original data and subjectsCode:- All code required to re-create analyses and figures are provided as .R files.- The two "master_script_" files are required to be run prior to recreating figures. Objects that figure creation relies on are generated by the master scripts- Files to support the master scripts are house in /data_import_scripts, but do not need to be called directly by the user. Rather, the master scripts will source these auxiliary files automatically as needed.- Code for each figure is provided within separate .R files. Multi-panel plots are created wherever possible, but might differ slightly in presentation from their final format due to rendering differences across platforms.</p
