چکیده
My dissertation work has been twofold. The first part focuses on enhancing cellphone awareness with the purpose of minimizing inappropriate cellphone interruptions and to create more socially intelligent and thus accepted cell phones. I have introduced, designed, and investigated three different approaches toward that goal. The approaches capitalize on the emerging fields of ubiquitous computing, context-awareness and smart environments and are intended to function in a minimally intrusive manner. The second part focuses in exploring privacy implications and sharing preference and patterns for context-aware telephony as well as developing techniques that best evaluate privacy concerns in natural settings.

Limonoids from Citrus reticulata.
The seeds of Citrus reticulata afforded the new limonoid derivative, isolimonexic acid methyl ether, in addition to the previously isolated limonin, deacetylnomilin, obacunone and ichangin. The structure elucidation was achieved primarily through 1D and 2-D-NMR analyses. The marginal antimalarial activity of isolimonexic acid methyl ether is reported.
متن کاملSynthesis and anticonvulsant activity of new 3'-aryl- 7-bromo-spiro[ [1]benzothiophene-3,2'-[1,3] thiazolidine]-2,4'-dione derivatives
Two series of spiro[ [1]benzothiophene-3,2'-[1,3]thiazolidine]-2,4'-diones 5a-e and 6a-e were synthesized, characterized and evaluated for anticonvulsant activity. Reaction of [1]benzothiophene-2,3-dione (3) with certain arylamines afforded the corresponding Schiff bases 4a-e. Cyclization of 4a-e with thioglycolic or thiolactic acids brought about the target spiro compounds 5a-e and 6a-e respec...
متن کاملTowards Automatic Device Configuration in Smart Environments
As the number of mobile devices we carry grows, the job of managing those devices throughout the day becomes cumbersome. In addition, the ability to use mobile devices in unethical ways without being detected is becoming widespread [13-14]. It is desirable for mobile devices to automatically configure themselves based on the context of the environment and user preferences for both convenience a...
متن کاملDo I Do What I Say?: Observed Versus Stated Privacy Preferences
This paper examines the use of surveys in measuring privacy concerns in ubiquitous computing environments. Two evaluation techniques are used to study the privacy concerns of sharing context information: a paper based survey and in-situ questionnaires. Results from the two techniques differ significantly, suggesting that surveys are not reliable in predicting privacy concerns regarding context-...
