Information architecture for selling home-cooked food site
No full textInformation Architecture is an important component of User Experience, but also one that can be easily overlooked. It is needed so that a user can easily navigate and search through a website. This thesis includes an introduction to the different components of Information Architecture: The Organization System, the Labeling System, the Navigation System, and the Search System. The thesis also goes through on how Information Architecture can be implemented through the use of User Research, Visual Sitemaps, Wireframe Designs, and the Visual Design choices concerning color and the font. The theory of Information Architecture and the implementation of these features are showcased in an example Cake Shop website. The Cake Shop website was built in Adobe XD and was used to aid in the understanding of the concept. Using this thesis as a base, the reader should be to implement the components of Information Architecture and provide a more structured way of presenting information
Oral History of Thu Huyen
No full textAn oral history of Thu Huyen, a Vietnamese refugee living Orange County. She was born in 1942 in Nam Dinh. The interview primarily focuses on her account of surviving the war, escaping the newly Communist country, and re-establishing her family in the United States. This interview also features Thu’s husband, Phuoc Tran. His account was more geared towards the political turmoil rather than the domestic difficulties.Recorded Digitall
Influence of permanent dipole and dynamic core-electron polarization on tunneling ionization of polar molecules
No full textCitation: Hoang, V. H., Zhao, S. F., Le, V. H., & Le, A. T. (2017). Influence of permanent dipole and dynamic core-electron polarization on tunneling ionization of polar molecules. Physical Review A, 95(2), 8. doi:10.1103/PhysRevA.95.023407We present a detailed theoretical investigation on strong-field ionization of polar (CO and NO) as well as nonpolar molecules (N-2, O-2, and CO2). Our results indicate that accounting for the Stark correction in the molecular tunneling ionization theory leads to overall fairly good agreements with numerical solutions of the time-dependent Schrodinger equation. Furthermore, we show that the effect of dynamic core-electron polarization, in general, has a weak influence on the angle-dependent ionization probability. However, in the case of CO we confirm the recent finding by B. Zhang, J. Yuan, and Z. Zhao [Phys. Rev. Lett. 111, 163001 (2013)] that accounting for dynamic core-polarization is crucial to achieving an overall good agreement with experiments
Replication Data for: E-government service quality, perceived value, satisfaction, and loyalty: Evidence from a newly emerging country
No full textThis study integrates two chain models, service quality–perceived value–loyalty and perceived value–satisfaction–loyalty, to examine the relationships between e-government service quality, citizen perceived value, citizen satisfaction, and citizen loyalty towards e-government services. Survey data were collected from 340 randomly selected e-government service users in Vietnam. The data were analyzed using SPSS and AMOS software. The results reveal that (1) e-government service quality comprised of five dimensions: ease of interaction, fulfillment, citizen care, security and privacy, and trustworthiness, (2) among the five dimensions of e-government service quality, only trustworthiness and fulfillment have significant effects on perceived value, however, trustworthiness more strongly influences perceived value than does fulfillment, and (3) both perceived value and satisfaction are positively related to loyalty. Theoretical and managerial implications are discussed. (2023-07-22) (2023-07-23

The results indicate that the e-government can create value for the citizens by improving service quality, which may help satisfy citizens' needs and build their loyalty
Unifying Access and Resource Usage Control over Standard Client-Server Interactions
No full textWe propose a novel framework for integrated access and resource usage control over standard clientserver interactions. Historically, access control has been developed without considering resource usage. Resource control has thus developed as an ad hoc server-centric set of mechanisms (e.g., file system quota, network bandwidth quote, etc.). We believe that resource usage control is strongly related to access control and so should be implemented using a unified, global enforcement framework. We introduce such a framework, where services have resource usage constraints and principals have resource usage histories. To access and use a service, a principal must have the appropriate access and sufficient resource usage rights when considering its usage history. Our framework is able to enforce global stateful policies, yet do not require changes to existing message-passing applications. We have built a prototype and used it to specify and enforce an example policy that includes role-based control and delegation. We applied our system to control access and resource usage for three different services, network, DNS, and SMB file systems, to demonstrate its effectiveness and wide applicability.Technical report DCS-TR-67

GreenSlot: Scheduling Energy Consumption in Green Datacenters
No full textIn this paper, we propose GreenSlot, a parallel batch job scheduler for a datacenter powered by a photovoltaic solar array and the electrical grid (as a backup). GreenSlot predicts the amount of solar energy that will be available in the near future, and schedules the workload to maximize the green energy consumption while meeting the jobs’ deadlines. If brown energy must be used to avoid deadline violations, the scheduler selects times when brown electricity is cheap. Our results for production scientific workloads demonstrate that GreenSlot can increase green energy consumption by up to 117% and decrease energy cost by up to 39%, compared to EASY backfilling. Based on these positive results, we conclude that green datacenters and green-energy-aware scheduling can have a significant role in building a more sustainable IT ecosystem.Technical report DCS-TR-68
Examining Race/Ethnicity Diversity in the Enrollment of a 4-year CS University Program
No full textComputing departments in the United States are not producing the number of graduates that the workforce needs. At the same time, they lack gender and racial diversity. Therefore, it is important to attract students from minority groups that comprise a significant part of the US population and can bring an enriching, diverse perspective to the development of new technology. In this paper, we study patterns of enrollment and retention among minority students in a 4-year CS university program in order to better understand the challenges for increasing racial and ethnic diversity. We use student data from three core CS classes with a special focus on the introduction to programming (CS1) class. We compare the ethnic makeup of our CS enrollment with that of the student population at our university, that of the state and with nationwide numbers, and examine how the ethnic gap changes from an introductory programming class to an upper level class. We also analyze how different factors such as intent to major, prior experience in computing, and CS1 grades correlate with student retention
Unified Structure and Content Search for Personal Information Management Systems
No full textThe amount of data that users are storing and accessing in personal information systems is growing massively. At the same time, the organization of this data is becoming more heterogeneous, with data spread across different organizational domains such as emails, music databases, and photo albums, some of which are structured by applications rather than users. Powerful search tools are needed to help users locate data in these rapidly expanding yet fragmented data sets. In this paper, we present a novel fuzzy search approach that considers approximate matches to structure and content query conditions. Our approach includes a scoring framework for computing unified relevance scores for potential answers. Critically, our framework uses unified data and query processing models so that structure conditions can be approximately matched by content inside files and vice versa. Our model also unifies external structure (directories) with internal structure (e.g., XML structure), allowing users to specify integrated queries that are matched to a single unified data domain. We propose indexes and algorithms for efficient query processing. Finally, we empirically evaluate our approach using a real data set. We show that our unified fuzzy search approach can leverage structure information to significantly improve search accuracy, yet is robust to mistakes in query conditions.Technical report DCS-TR-66
