The Impact Of Property Flipping On Single Family Detached Home Prices, Wesley H. English Nov 2005

The Impact Of Property Flipping On Single Family Detached Home Prices, Wesley H. English

Business Administration Theses - Archive

In 2003 HUD ruled that flipped properties, which are defined as recently acquired properties that have been resold, often within days, and for a substantial profit, are ineligible for FHA insured mortgage financing. This research uses the HUD ruling as the basis for this study. Their ruling was based on the perception that property flipping had a negative effect on home prices among other things. The study uses hedonic modeling to empirically determine if houses that have previously flipped have any influence on value when compared to the non-flipped properties in the same market. Through a regression analysis, it is …

Optimization Of H.264 Baseline Decoder On Arm9tdmi Processor, Sandya B. Sheshadri

Electrical Engineering Theses - Archive

With the newly introduced features and advancements to the pre-existing features, the emerging H.264 video coding standard achieves significant improvements in coding performance over all existing standards, in a wide variety of applications. The coding-efficiency advantages of H.264, however, come at the expense of higher computational complexity. H.264 decoders can exhibit more than double the complexity of H.263 decoders. Furthermore, previous studies have shown that fractional-pixel motion-compensation interpolation and the loop filtering consume a significant amount of computational power in emerging H.264 decoders. Since these operations are part of the baseline profile of H.264, there is a need to evaluate …


A Novel Game Theoretic Framework For Security In Wireless Sensor Networks, Afrand Agah Nov 2005

A Novel Game Theoretic Framework For Security In Wireless Sensor Networks, Afrand Agah

Computer Science and Engineering Dissertations - Archive

Due to severe resource limitations and often lack of centralized infrastructure, providing security in wireless sensor networks is a great challenge. Misbehavior due to malicious or faulty nodes can significantly degrade the performance of such networks. Therefore, countermeasures against denial of service (DoS) attacks and node misbehavior are essential requirements. We argue that the conventional view of security based on cryptography techniques is not sufficient for securing wireless sensor networks. In this dissertation, we investigate a novel framework by proposing three approaches for security enforcement in such networks that range from prevention of DoS attacks to secure routing. Prevention of …

Modeling And Feedback Control Of Mems Devices, Bruno Borovic Nov 2005

Modeling And Feedback Control Of Mems Devices, Bruno Borovic

Electrical Engineering Dissertations - Archive

As MEMS actuators reach maturity and emerge from the research lab into commercial applications, their increased reliability, speed, and performance accuracy is needed. MEMS are typically driven directly in an open-loop fashion by applying simple actuating signals. The requirements for better dynamical behavior, however, have resulted in the gradual introduction of improved actuation approaches, such as pre-shaped open-loop driving and closed-loop control. Unlike macro mechanical systems where the implementation of the feedback is relatively simple, it is quite problematic in the MEMS case. The presence of fast system dynamics, and physical area efficiency requirements have introduced additional challenges for feedback …


Service Discovery By Automated Structural And Semantic Matching, Alan Walker Nov 2005

Service Discovery By Automated Structural And Semantic Matching, Alan Walker

Computer Science and Engineering Theses - Archive

Pervasive computing systems need to locate and use services dynamically. Current models of service location and interaction rely on a fixed contract, or service description, located by name and/or a combination of keywords. This implies a priori agreement on the service description, leading to fragility and the inability for systems to interoperate unless they were built to match an existing standard. This thesis implements a technique for relaxing the fixed contract assumption, so that the nearest match amongst a set of services can be located. The system takes into account structural, data type and naming differences. The naming differences are …

Stock Options: To Expense Or Not To Expense. A Comparison Of Economic Determinants, Firm Payoffs, And Pay-Performance Sensitivity Of Executive Stock Option Compensation, Barbara Wood

Finance and Real Estate Dissertations - Archive

Until June 2005, firms had a choice in accounting for stock option compensation. The majority of firms elected to disclose option compensation expense in the footnotes of their financial statements. However, after the accounting scandals in the early 2000s, many firms moved from disclosing the expense to recognizing the expense as a charge against earnings. This research examines the reasons that firms would voluntarily elect to adopt option recognition prior to regulatory requirement. The decision to recognize option pay is examined with respect to efficient contracting, earnings management, and information signaling. Firms that elect to expense option pay do so …
