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 Nov 2005

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 …

Field And Experimental Studies To Assess The Performance Of Stabilized Expansive Clay, Gautham S. Pillappa Aug 2005

Field And Experimental Studies To Assess The Performance Of Stabilized Expansive Clay, Gautham S. Pillappa

Civil Engineering Theses - Archive

A vast majority of the expansive soils are montmorillonite-rich clays, over consolidated clays and shales. The swell and shrinkage movements of expansive soil cause considerable damage to structures such as buildings and pavements. This damage can be attributed to moisture fluctuations caused by seasonal variations. Volumetric changes typically appear in the form of cracks which will lead to the softening and vertical heaving in subsoils. Both softening and vertical expansion induce damage to overlying structures. Certain soils rich with sulfates exhibit swell and heaving even after treatment with stabilizers. The present research project was conducted at the University of Texas …
