Quick Abstract

Bare PC Web servers that run on 32-bit or 64-bit machines and use TCP or UDP for transport have been built previously. This paper describes the design and implementation of a new stateless UDP-based bare PC multi-core Web server. It also presents performance measurements. The server extends previous server designs with several novel architectural and protocol enhancements. A load balancing technique suitable for multi-core servers is included to illustrate a simple way to efficiently process HTTP requests. The architecture presented here could be adapted in future to build simple conventional Web servers.

Insights into Transforming a Linux Wireless Device Driver to Run on a Bare Machine

Topics: Software and Systems Development Methodologies; System Complexity

Proceedings of ENASE 2015, ISBN: 978-989-758-100-7

Quick Abstract

Developing device drivers is often tedious and error-prone. Drivers for bare machine applications that run without an OS have been previously written by directly using specification documents. Transformation is an alternate approach that attempts to develop a bare machine driver by using existing code for an OS driver. We investigate the transformation of a Broadcom Linux 802.11n wireless device driver to a bare machine driver. As a first step towards understanding the transformation, we study the functions and OS dependencies of the Linux driver. The driver module is analyzed by examining its interaction with other modules, providing details of its key elements and code sizes, and by comparing code sizes with its counterpart Windows driver. We also discuss design issues that will be useful for developing device drivers that are independent of any operating system, kernel, or embedded system.

Digital Object Identifier: 10.5220/0005509002330245

Proceedings of ICE-B 2015/ICETE, ISBN: 978-989-758-113-7

Quick Abstract

This study investigates the impact of the several dimensions of Hofstede’s cultural framework on the adoption rates of social networking sites (SNS) across 30 countries, while controlling for a country’s median age, its urban population level and mobile internet penetration. Hierarchical regressions are conducted. Our findings reveal that three cultural dimensions, i.e., masculinity/femininity, uncertainty avoidance and long-term orientation, significantly impact nations’ adoption levels of SNS above and beyond the effects of median age and urban population level. While there is a growing body of literature that examines the influence of national culture on the adoption and use of a variety of high-tech innovations and services mediated by these technologies, our study is among the first to specifically relate cultural perspectives to country adoption levels of social networking sites using an array of cultural dimensions. We provide a theoretical framework and supporting empirical evidence to underscore the importance of understanding how culture impacts consumers’ SNS adoption behavior across countries. Implications from our findings, limitations and directions for future research are provided.

Quick Abstract

Computer science, information systems, information technology and other related programs have been evolving over the years to prepare students for the ever changing work force or to become research scientists. These program structures and curriculum gets updated rapidly even before a student had a chance to complete a four year cycle. When a student graduates, there may be a daunting challenge to find a right fit for a right job in today’s global market. This paper proposes a curriculum paradigm that is based on sound engineering principles and need for applied education. The curriculum proposed here is based on student needs and industry outlook. It reduces educational cost for students, administrative cost for teaching institutions and training cost for industry. It also provides a first cut of curriculum that integrates a variety of disciplines under the information technology umbrella. The curriculum taxonomies are shown to illustrate the proposed concept. An initial road map and time schedules are shown to demonstrate the feasibility of this concept. The roles of students, faculty and industry supervisors are discussed. The approach proposed here will have a broader positive impact in information technology when adopted. Further research is needed to fully exploit the proposed concept.

Digital Object Identifier: 10.5220/0004868600160025

Proceedings of ENASE 2014, ISBN: 978-989-758-030-7

Quick Abstract

Enterprise architecture (EA) has demonstrated utility for improving overall Information System (IS)/Information Technology (IT) outcomes for institutions, particularly those with large-scale or integration-related needs. To achieve the core goal of an EA – integration, alignment and governance between enterprise goals and the enterprise IS/IT portfolio – institutional vision, mission and objectives must be elicited, analysed, understood and documented by the enterprise architects. This paper proposes and evaluates a lightweight EA elicitation technique to gather the required information about enterprise mission and objectives as a lightweight entry point to developing an EA. Specifically, we investigate the evaluation results of our proposed technique in EA data elicitation and analysis stemming from a case study that was conducted on an institution with a significant IS/IT asset portfolio. Our proposed EA elicitation technique utilizes the VMOST elicitation question, a structured elicitation vehicle, and Grounded Theory Method as the qualitative analysis technique to analyse elicited responses. Application of this approach in a real case study garnered sufficient understanding the vision, mission and objectives of an enterprise to articulate objectives in a way suitable to use as institutional goal as a part of the Zachman EA framework.

Quick Abstract

Thanks to modern networking technologies and advancement of social networks, people in the modern society need more and more information just to be in the game. With such environment, the importance of learning and information sharing cannot be overemphasized. Even though plethora of information is available on various sources such as the web, libraries, and any learning material repositories, if it is not readily available and meets the needs of the user, it may not be utilized. For that, we need a system that can help provide customized information – matches with user’s level and interest - to the user. Such system should understand what the user’s interests are, what level the user belongs for the topic, and so on. In this paper, we are proposing a framework for smart learning management system (SLMS) that utilizes user profiles and semantically organized learning objects so only the relevant information can be delivered to the user. The SLMS maintains user profiles – continuously updating whenever there is a change – and learning objects that are organized by building ontology. Upon user’s request, the system fetches relevant learning materials based on the user’s profile. The delivered learning materials are suitable for the user’s topic and the level for the requested topic sorted by relevancy ranking.

Transforming SQLITE to Run on a Bare PC

Topic: Model Transformation

Authors: Uzo Okafor , Ramesh K. Karne , Alexander L. Wijesinha and Bharat S. Rawal

Quick Abstract

SQLITE is a popular small open-source database management system with many versions that run on popular platforms. However, there is currently no version of the SQLITE application that runs on a bare PC. Since a bare PC does not provide any form of operating system (or kernel) support, bare PC applications need to be completely self-contained with their own interfaces to the hardware. Such applications are characterized by small code size, and have inherent security and performance advantages due to the absence of a conventional operating system. We describe a general transformation approach that can be used to transform the SQLITE application to a lean SQLITE application that runs on a bare PC. We present the current state of this work and identify several important issues that need further research.

Authors: Yuanqiong Wang and John Schoeberline

Affiliation: Towson University, United States

Digital Object Identifier: 10.5220/0003504602970303

Proceedings of ICEIS 2011, ISBN: 978-989-8425-56-0

Quick Abstract

Group support applications are widely used in workplace. Unfortunately, persons who are blind often find difficult to access such applications, due to the highly graphical nature of the applications, which hinders their ability to contribute to the group. As the result, persons who are blind are often face problems gaining and retaining employment. This paper presents preliminary results of a series of focus group study conducted in the mid-Atlantic region on accessibility and usability issues of group support applications. How persons who are blind utilize group support applications to support their group tasks; the tasks/steps utilized to complete a group project; and, the accessibility and usability issues experienced by blind users are discussed. Additionally, the focus group study identified the reasons persons who are blind discontinued utilizing group support applications; the other tools utilized to support group work; the accessibility design considerations; and, the accessibility documentation and support needed.

Proceedings of ICE-B 2007/ICETE, ISBN: 978-989-8111-11-1

Quick Abstract

This paper proposes the integrated design of an event stream service system architecture (ESSSA) which can be used as a gateway to capture and process enormous amounts of event streams continuously generated by radio frequency identification (RFID) or variable sensors over ubiquitous sensor network (USN) installed in a wide variety of locations, transfer the refined events to the various event-driven applications connected to this architecture, and allow the corresponding actions to be taken by the applications. The events continuously delivered from versatile origins and their streams are inherently uncertain, unbounded, and time-varying. Their arrival rate might severely fluctuate in some cases. Accordingly, this design focuses on the elaborate handling of the event streams by facilitating robust event gathering scheme as a front-end gateway in combination with a back-end event processing engine. The paper also contains the time-varying event query processing schemes of the ESSSA by extending the object-relational spatial database management system, ZEUS. The ESSSA can be applied as a framework for interfacing RFID or USN sensor based applications such as an enterprise resource planning system (ERP), a supply chain management system (SCM), a warehouse management system (WMS), or a centralized command and control system.
