UTP CarPool System

Transportation has been one of the main problems with students in university, especially for university in the remote area. Only a minor portion of students has their own transport, more over, the University Tecknologi Petronas is located far away from the city, students there have faced a lot of difficulties when they want to go out of the campus. UTP car pooling system has been developed with the purpose to overcome that problem. The system will let a student share his private vehicle with one or more people that have common or aligned destination. This concept has been familiar in the United State and many countries in Europe but not in Malaysia. UTP Car Pooling System is a web based system will be implemented by open source software, which will bring the flexibility and reusability to the system. Apache will be used as Web Server while MySql will be the backend Database. PHP will act as a middleware, to generate the dynamic content to display at the client side. Because of mobile blooming and characteristic of car pooling system, the system will take the advantage of wireless technology to provide service to mobile users via their hand phones. The system development will consist of three phases with three particular versions. During the first phase, the system will be set up on PC platform, so that user can access the service via their computers. After the second phase, a lot of enhancement will be made such as ability to notify users via email and SMS. The last phase will produce another version for micro browser, which is totally supported by every hand phone. At that time, UTP Car Pooling System will have ability to bring an alternative method of transportation to UTP student, which can help them to overcome one of their main problems. Mobility is the main characteristic that makes UTP car pool system different from others one. Most of the systems now, based on author's research does not support handphone as well as SMS notification, which are the most used in communication. Therefore, UTP CarPool System does not only promote this concept system in UTP as well as Malaysia, but also a deep enhancement of car pool system fields

Efficient layering for high speed communication: the MPI over Fast Messages (FM) experience

We describe our experience of designing, implementing, and evaluating two generations of high performance communication libraries, Fast Messages (FM) for Myrinet. In FM 1, we designed a simple interface and provided guarantees of reliable and in-order delivery, and flow control. While this was a significant improvement over previous systems, it was not enough. Layering MPI atop FM 1 showed that only about 35 % of the FM 1 bandwidth could be delivered to higher level communication APIs. Our second generation communication layer, FM 2, addresses the identified problems, providing gather-scatter, interlayer scheduling, receiver flow control, as well as some convenient API features which simplify programming. FM 2 can deliver 55–95 % to higher level APIs such as MPI. This is especially impressive as the absolute bandwidths delivered have increased over fourfold to 90 MB/s. We describe general issues encountered in matching two communication layers, and our solutions as embodied in FM 2

Guaranteed bandwidth implementation of message passing interface on workstation clusters

Due to their wide availability, networks of workstations (NOW) are an attractive platform for parallel processing. Parallel programming environments such as Parallel Virtual Machine (PVM), and Message Passing Interface (MPI) offer the user a convenient way to express parallel computing and communication for a network of workstations. Currently, a number of MPI implementations are available that offer low (average ) latency and high bandwidth environments to users by utilizing an efficient MPI library specification and high speed networks. In addition to high bandwidth and low average latency requirements, mission critical distributed applications, audio/video communications require a completely different type of service, guaranteed bandwidth and worst case delays (worst case latency) to be guaranteed by underlying protocol. The hypothesis presented in this paper is that it is possible to provide an application a low level reliable transport protocol with performance and guaranteed bandwidth as close to the hardware on which it is executing. The hypothesis is proven by designing and implementing a reliable high performance message passing protocol interface which also provides the guaranteed bandwidth to MPI and to mission critical distributed MPI applications. This protocol interface works with the Fiber Distributed Data Interface (FDDI) driver which has been designed and implemented for Performance Technology Inc. commercial high performance FDDI product, the Station Management Software 7.3, and the ADI / MPICH (Argonne National Laboratory and Mississippi State University\u27s free MPI implementation)

Overlapping of Communication and Computation and Early Binding: Fundamental Mechanisms for Improving Parallel Performance on Clusters of Workstations

This study considers software techniques for improving performance on clusters of workstations and approaches for designing message-passing middleware that facilitate scalable, parallel processing. Early binding and overlapping of communication and computation are identified as fundamental approaches for improving parallel performance and scalability on clusters. Currently, cluster computers using the Message-Passing Interface for interprocess communication are the predominant choice for building high-performance computing facilities, which makes the findings of this work relevant to a wide audience from the areas of high-performance computing and parallel processing. The performance-enhancing techniques studied in this work are presently underutilized in practice because of the lack of adequate support by existing message-passing libraries and are also rarely considered by parallel algorithm designers. Furthermore, commonly accepted methods for performance analysis and evaluation of parallel systems omit these techniques and focus primarily on more obvious communication characteristics such as latency and bandwidth. This study provides a theoretical framework for describing early binding and overlapping of communication and computation in models for parallel programming. This framework defines four new performance metrics that facilitate new approaches for performance analysis of parallel systems and algorithms. This dissertation provides experimental data that validate the correctness and accuracy of the performance analysis based on the new framework. The theoretical results of this performance analysis can be used by designers of parallel system and application software for assessing the quality of their implementations and for predicting the effective performance benefits of early binding and overlapping. This work presents MPI/Pro, a new MPI implementation that is specifically optimized for clusters of workstations interconnected with high-speed networks. This MPI implementation emphasizes features such as persistent communication, asynchronous processing, low processor overhead, and independent message progress. These features are identified as critical for delivering maximum performance to applications. The experimental section of this dissertation demonstrates the capability of MPI/Pro to facilitate software techniques that result in significant application performance improvements. Specific demonstrations with Virtual Interface Architecture and TCP/IP over Ethernet are offered

Open source SCADA systems for small renewable power generation

Low cost monitoring and control is essential for small renewable power systems. While large renewable power systems can use existing commercial technology for monitoring and control, that is not cost-effective for small renewable generation. Such small assets require cost-effective, flexible, secure, and reliable real-time coordinated data monitoring and control systems. Supervisory control and data acquisition (SCADA) is the perfect technology for this task. The available commercial SCADA solutions are mostly pricey and economically unjustifiable for smaller applications. They also pose interoperability issues with the existing components which are often from multiple vendors. Therefore, an open source SCADA system represents the most flexible and the most cost-effective SCADA solution. This thesis has been done in two phases. The first phase demonstrates the design and dynamic simulation of a small hybrid power system with a renewable power generation system as a case study. In the second phase, after an extensive study of the proven commercial SCADA solutions and some open source SCADA packages, three different secure, reliable, low-cost open source SCADA options are developed using the most recent SCADA architecture, the Internet of Things. The implemented prototypes of the three open source SCADA systems were tested extensively with a small renewable power system (a solar PV system). The results show that the developed open source SCADA systems perform optimally and accurately, and could serve as viable options for smaller applications such as renewable generation that cannot afford commercial SCADA solutions

Communication Strategies’ Impact on Finances at Kentucky Higher Education Institutions During the COVID-19 Pandemic

Kentucky public higher education institutions faced a financial cliff with the onset of the COVID-19 pandemic (Capilouto, 2021 Jan.). Campuses across the state closed in spring 2020, with the list of unknowns outnumbering the knowns by a significant margin (Monday, E., Blanton, J., and Kiser, K., 2021). In the face of an unknown future, administrations at Kentucky institutes of higher education relied upon communication strategies more than ever to outline Universities’ plans for reopening, reinvented operational plans, outlining contingencies, and fulfilling an invaluable role in efforts to test, contact trace and eventually vaccinate campus and broader community populations. This project will seek to determine to what extent communication strategies and the effective dissemination of information created an environment for universities to weather the COVID-19 financial storm

Cultivating Reform: Richard Nixon\u27s Illicit Substance Control Legacy, Medical Marijuana Social Movement Organizations, And Venue Shopping

Over the course of the last two decades, organizations representing the medical marijuana social movement have campaigned for, proposed state level legislation, and supported numerous legal arguments that challenge and attempt to reform U.S. federal illicit substance policies. This set of social regulatory policies, commonly known as the Controlled Substance Act of 1970 (CSA), were drafted, promoted, and implemented by the Nixon Administration then subsequently entrenched by multiple presidents with acquiescent congresses adopting supplemental supply-side resource allocating legislation. My dissertation research uncoils the convoluted history and institutional dynamics of path dependent U.S. illegal drug control policies to answer the question of how social movement organizations (SMOs) challenge and reform executively entrenched policies. First, I examine the Nixon Administration\u27s decision-making process via archival materials in order to understand why and how the CSA was framed, introduced, and ratified. Second, two presidential illicit substance control case studies (Ronald Reagan and George H.W. Bush) are presented to demonstrate how U.S. illicit substance control is executively entrenched. Third, periodical challenges prior to the first state-level medical marijuana law are presented as antecedent and instructional to contemporary SMO institutional mobilization. Last, through interviews, media portrayals, and institutional rulings I demonstrate how medical marijuana SMOs have reframed the drug\u27s definition then shopped institutional venues for the purpose of reforming existing policies
