Reflectivity measurements on hot reactive liquids using an FIR laser

The experimental procedures and precautions required to measure liquid-alloy reflectivities with a cw far infrared (FIR) laser are described. The output of a carefully stabilized optically pumped FIR laser was channeled to a melted sample contained in a silica holder under a He atmosphere. By maintaining specular reflection and alloy homogeneity, reflectivities reproducible to ± 7% were routinely obtained

An Investigation into the development of an interactive archival catalog of art within the Rochester Institute of Technology

RIT has no complete visual and /or factual catalog of the pieces of art presently displayed in public areas. Many pieces of work on campus are in desperate need of repair as well as plaques to identify the work. Visions, the only known bound record of a selection of artwork on the Henrietta campus, was produced by the RIT Communications Office in 1975. The Archives in Wallace Memorial Library have a small collection of slides of various artworks, however, many works of art are currently missing. Several valuable pieces of work were lost in the move from the city campus to Henrietta, and some pieces have yet to be removed from storage in Physical Plant. RIT is not fully aware of what is currently located in public areas. This interactive catalog will create a complete visual and factual catalog of the artwork located in public areas on the RIT Henrietta campus. Being interac tive, this catalog will include full-color images, sound, QuickTime movie clips and text about the piece of work, its location on campus, the artist, as well as any other relevant information that can be gathered on the work. The catalog will be user-friendly so that anyone with little or no computer experience will have no trouble operating the program. Information on the artwork along with a full-color image of the piece will be displayed on each card. This interactive archival catalog will be simple for anyone to use. People with or without computer skills or experience with multimedia applications should discover that this catalog is a faster and more entertaining way to retrieve data. This thesis will investigate past, present and future storage meth ods for information. In addition, this project will research how effective interac tive archival storage is. Upon completion, the Interactive Archival Catalog will be tested by thirty students from the School of Fine and Applied Arts, the College of Photographic Arts and Sciences, and the School for Printing Management and Sciences. The students will be asked to play with the catalog for at least ten minutes and then answer some questions about it. The questions and responses can be found in Chapter 6, page 35. All comments and suggestions were noted and changes that needed to be made were corrected. The purpose of this catalog is to introduce the RIT community to the art work present on campus. Implementing interactive multimedia makes the data search experience an enjoyable and interesting one. If the catalog is successful, people will develop an appreciation of the artwork on this campus as well as an interest in interactive data storage and retrieval systems

The Impact of Encoding and Transport for Massive Real-time IoT Data on Edge Resource Consumption

Edge microservice applications are becoming a viable solution for the execution of real-time IoT analytics, due to their rapid response and reduced latency. With Edge Computing, unlike the central Cloud, the amount of available resource is constrained and the computation that can be undertaken is also limited. Microservices are not standalone, they are devised as a set of cooperating tasks that are fed data over the network through specific APIs. The cost of processing these feeds of data in real-time, especially for massive IoT configurations, is however generally overlooked. In this work we evaluate the cost of dealing with thousands of sensors sending data to the edge with the commonly used encoding of JSON over REST interfaces, and compare this to other mechanisms that use binary encodings as well as streaming interfaces. The choice has a big impact on the microservice implementation, as a wrong selection can lead to excessive resource consumption, because using a less efficient encoding and transport mechanism results in much higher resource requirements, even to do an identical job

End-to-end slices to orchestrate resources and services in the cloud-to-edge continuum

Fog computing, combined with traditional cloud computing, offers an inherently distributed infrastructure – referred to as the cloud-to-edge continuum – that can be used for the execution of low-latency and location-aware IoT services. The management of such an infrastructure is complex: resources in multiple domains need to be accessed by several tenants, while an adequate level of isolation and performance has to be guaranteed. This paper proposes the dynamic allocation of end-to-end slices to perform the orchestration of resources and services in such a scenario. These end-to-end slices require a unified resource management approach that encompasses both data centre and network resources. Currently, fog orchestration is mainly focussed on the management of compute resources, likewise, the slicing domain is specifically centred solely on the creation of isolated network partitions. A unified resource orchestration strategy, able to integrate the selection, configuration and management of compute and network resources, as part of a single abstracted object, is missing. This work aims to minimise the silo-effect, and proposes end-to-end slices as the foundation for the comprehensive orchestration of compute resources, network resources, and services in the cloud-to-edge continuum, as well acting as the basis for a system implementation. The concept of the end-to-end slice is formally described via a graph-based model that allows for dynamic resource discovery, selection and mapping via different algorithms and optimisation goals; and a working system is presented as the way to build slices across multiple domains dynamically, based on that model. These are independently accessible objects that abstract resources of various providers – traded via a Marketplace – with compute slices, allocated using the bare-metal cloud approach, being interconnected to each other via the connectivity of network slices. Experiments, carried out on a real testbed, demonstrate three features of the end-to-end slices: resources can be selected, allocated and controlled in a softwarised fashion; tenants can instantiate distributed IoT services on those resources transparently; the performance of a service is absolutely not affected by the status of other slices that share the same resource infrastructure

Developing and Measuring Parallel Rule-Based Systems in a Functional Programming Environment

This thesis investigates the suitability of using functional programming for building parallel rule-based systems. A functional version of the well known rule-based system OPS5 was implemented, and there is a discussion on the suitability of functional languages for both building compilers and manipulating state. Functional languages can be used to build compilers that reflect the structure of the original grammar of a language and are, therefore, very suitable. Particular attention is paid to the state requirements and the state manipulation structures of applications such as a rule-based system because, traditionally, functional languages have been considered unable to manipulate state. From the implementation work, issues have arisen that are important for functional programming as a whole. They are in the areas of algorithms and data structures and development environments. There is a more general discussion of state and state manipulation in functional programs and how theoretical work, such as monads, can be used. Techniques for how descriptions of graph algorithms may be interpreted more abstractly to build functional graph algorithms are presented. Beyond the scope of programming, there are issues relating both to the functional language interaction with the operating system and to tools, such as debugging and measurement tools, which help programmers write efficient programs. In both of these areas functional systems are lacking. To address the complete lack of measurement tools for functional languages, a profiling technique was designed which can accurately measure the number of calls to a function , the time spent in a function, and the amount of heap space used by a function. From this design, a profiler was developed for higher-order, lazy, functional languages which allows the programmer to measure and verify the behaviour of a program. This profiling technique is designed primarily for application programmers rather than functional language implementors, and the results presented by the profiler directly reflect the lexical scope of the original program rather than some run-time representation. Finally, there is a discussion of generally available techniques for parallelizing functional programs in order that they may execute on a parallel machine. The techniques which are easier for the parallel systems builder to implement are shown to be least suitable for large functional applications. Those techniques that best suit functional programmers are not yet generally available and usable

The introduction of brachytherapy to the country of Botswana

Low and middle-income countries (LMICs) around the world are experiencing a global cancer crisis. For treatable disease, cancer specific mortality in LMICs is much higher than in high-income countries. Botswana is a middle-income country in Sub-Saharan Africa that had its population decimated by the AIDS epidemic. In the aftermath and due to the successful implementation of an anti-retroviral program, patients are living longer and are developing cancer. Cervical cancer is one of the leading causes of death in women around the world, but it is curable. Patients in Botswana live far from treatment centers and therefore often present with locally advanced disease that can be cured with a combination of chemotherapy, external beam radiation therapy and brachytherapy. The goal of this present study is to describe the challenges and implementation of brachytherapy in the country of Botswana in 2012 and to report its uses within the cervical cancer population between 2012 and 2014. The government of Botswana recognized that there was a need for in country brachytherapy to help reduce the cervical cancer burden. A public-private partnership was negotiated through the government of Botswana in order to bring brachytherapy into the country. In March 2011, a Nucletron HDR-Brachytherapy unit that uses Ir-192 was installed at Gaborone Private Hospital. Longitudinal support from international partners provided instruction in insertion, dosimetry, physics and management of complications. The initial burden of patients presented with severe cervical fibrosis and vaginal stenosis due to late presentation of disease. This resulted in numerous complications in the first treatments, which included failed insertions, perforations and bleeding. Following training and support from international partners, complications have been reduced. There are about 45 insertions performed each month, with an average of 3 insertions per patient. Introduction of HDR Brachytherapy to Botswana has led to decreased treatment time, reduced complications, increased patient compliance and projected improved survival. Implementation of brachytherapy was facilitated by a public-private partnership and onsite mentorship by expert clinicians. Further research is needed to evaluate impact on patient quality of life and survival, and whether this experience can be replicated for other tumor sites

Reaching the Nations Through Our Cities

While the American public perceives New York City to be a post-Christian environment, reality is that the city is moving into a post-secular existence largely influenced by religious immigrants. These immigrants are symbolic of a new era in pioneer missions—one in which migration, transnationalism, globalization, and urbanization pose newer challenges and opportunities than uncharted geographies, isolated societies, and foreign cultures. “Reaching the Nations Through Our Cities” proposes that the next challenge for missionary pioneers is reaching busy, hidden, influential unreached peoples who have migrated to cities. Based on several years of research on the immigrant populations in Metro New York, this paper will seek to answer the question, “What will it take to reach the unreached peoples in our cities?
