A personal computer prototype to support ISDN service negotiations

Experience with a prototype service negotiation system for the integrated services digital network (ISDN) is presented. A commercially available database management system and high-level application language (dBASE III PLUS Version 1.1) were used as the platform on which to build the system. The user-system dialogue chosen for the prototype is a combination of menus and fill-in forms. The prototype was installed at Illinois Bell Telephone Company's Oak Brook facility and was used during negotiations for that company's ISDN trial. Additional prototyping efforts that built on these experiences are also reported. The prototyping activities demonstrate the feasibility of using PC-based prototypes, developed quickly using high-level languages with commercial tools, to identify issues specific to operations systems support for ISDN negotiations. <<ETX>>
REVIEW OF BLOOD CROSS-MATCH ORDERING AND TRANSFUSION PRACTICES FOR ELECTIVE HYSTERECTOMIES AT SAINT PAUL’S HOSPITAL MILLENNIUM MEDICAL COLLEGE: FIRST STEP TOWARDS A MAXIMUM SURGICAL BLOOD ORDERING SCHEDULE

ABSTRACT BACKGROUND: Requesting blood before surgery is a common practice. Studies show that majority of blood requested by surgeons are not utilized and this over ordering practices of blood will create a burden on the transfusion service. It diverts blood from the pool and makes it unavailable for other needy patients. OBJECTIVE: The objective of this study is to assess the blood requesting and utilization patterns in relation to elective hysterectomies preformed at Saint Paul’s Hospital Millennium Medical College (SPHMMC) in Addis Ababa. METHODOLOGY: A hospital based retrospective study was conducted at SPHMMC from February to March 2014. All elective hysterectomies performed in the time period of September 2011 to August 2013 were included for the study and the associated blood cross-match ordering and transfusion practice was audited. RESULT: A total of 532 units of blood were cross-matched for the 265 patients who underwent hysterectomies. But, of those only 74 (13.9%) units of blood were transfused to 39 (14.7%) patients. The findings of this study has also shown that for vaginal hysterectomy there is no need to prepare blood while for abdominal hysterectomy, abdominal hysterectomy with salpingo-oophorectomy and de-bulking surgery for ovarian tumour preparing only a unit of blood is enough. CONCLUSION: The results of the study showed that for most of the elective hysterectomies performed at SPHMMC, the level of blood utilization was minimal and there is significant over ordering of blood and associated wastage of resources. The process whereby fixed units of blood are requested for every patient irrespective of the diagnosis and type of surgical procedure should be revised. KEY WORDS: Surgery, elective hysterectomy, blood transfusion and transfusion indices (Ethiopian Journal of Reproductive Health 2016;8:1
Philosophical foundations of computer simulation validation

Innovations in information technology (IT) have been responsible for the rapid growth of computer simulation, which in turn has encouraged IT innovation. However, there is a striking contrast between the technological sophistication that drives and is driven by computer simulation and the rudimentary, underdeveloped state of theory underpinning the simulation endeavor. This article attempts to provide computer simulation with a theoretical framework by the application of philosophy of science to simulation validation. The authors discuss the key elements of Popper’s theory of falsification and explore how simulation validation is in fact anchored to Popper’s theory. Moreover, this article suggests that a Popperian perspective encourages the review of a validated model’s continuing validity, thereby potentially leading to the construction of a new, improved model. Finally, we contrast Popper’s falsificationist philosophy of science with Quine’s philosophical system of holism and early-period Putnam’s scientific realism, both of which discourage the building of better models.

ONLINE STREAM MINING APPROACH FOR CLUSTERING NETWORK TRAFFIC

A large number of research have been proposed on intrusion detection system, which leads to the implementation of agent based intelligent IDS (IIDS), Non – intelligent IDS (NIDS), signature based IDS etc. While building such IDS models, learning algorithms from flow of network traffic plays crucial role in accuracy of IDS systems. The proposed work focuses on implementing the novel method to cluster network traffic which eliminates the limitations in existing online clustering algorithms and prove the robustness and accuracy over large stream of network traffic arriving at extremely high rate. We compare the existing algorithm with novel methods to analyse the accuracy and complexity.
Performance analysis of shared buffer ATM switch with different cell departure models

The performance analysis of an asynchronous transfer mode (ATM) switch involves modeling the input traffic source, the switching mechanism, and the cell departure process. A main issue which determines the overall accuracy in performance evaluation of ATM switch, is the use of an appropriate probabilistic model to describe the cell departure process. Until now, little work has been done in the literature on characterizing the cell departure process for studying the performance of an ATM switch. This paper compares and verifies the accuracy of several models, including a new one called the "Urn model", which we propose. These models are put under test in a performance evaluation of a shared buffer ATM switch, by using a discrete-time Markov chain. The numerical results are compared to the simulation, and they show that the Urn model is a good compromise between accuracy and efficiency. This finding is significant because it helps to speed up the running of an analytical model of a large network while providing satisfactory accuracy.

2D vs. 3D Graphing Styles: A Comparison of the Accuracy of Reader Perceptions for 2D vs. 3D Graphs*

Students and researchers often choose a graphing style for the display of data based on the style’s aesthetic, rather than functional, qualities. Three-dimensional graphs may look more professional, but use of this style may negatively influence the accuracy of a reader’s perception of the presented information. The purpose of this study is to test perceptual accuracy of subjects when reading graphs rendered in a 2-dimensional versus a 3dimensional graphing style. The test was given to students via two mediums: paper and electronic. Results were analyzed to determine the degree to which accuracy is affected based on the style of graph used and the medium in which it is presented.
Concurrent High-performance Persistent Hash Table In Java

Current trading systems must handle both high volumes of trading and large amounts of trading data. One crucial module in high-performance trading is fast storage and retrieval of large volumes of data simultaneously accessed by multiple computer traders. To speed up access, a high-performance in-memory software-cache stores the dynamic working-set of trades during a trading day. To utilize memory effeciently, it is beneficial to provide a single shared cache for multiple trading applications. Much of the cache access is read-only, as information is gathered before a transaction to determine its value. Hence, extremely fast lookup is essential to support quick information gathering for assessment. This thesis presents a software-cache, called MapHash, that is a high-performance hash-table for use in Java.
A fuzzy logic based AGC algorithm for a radio communication system

This paper describes the implementation of a fuzzy logic automatic gain control (AGC) applied to amateur radio communications using ionospheric propagation mode and single side band radio equipment. A fuzzy logic algorithm was directly substituted for the original AGC algorithm, which resulted in an improved signal strength, clarity response and algorithm performance. A comparison between the division and a fuzzy logic based algorithms shows a reduction in RMS gain from 12.45 to 6.45 dB. Moreover, in signal clarity, the fuzzy based AGC algorithm obtained the best no-distortion rank. This implementation proves the feasibility of real-time fuzzy logic based AGC in communication systems.
Absolute Localization using Image Alignment and Particle Filtering

This paper presents a vision-based technique to determine the absolute location of a UAV using real-time image to map alignment. Normalized Cross-Correlation (NCC) is used to compare images taken onboard against photographic maps of the area. The NCC results are used to define a probability distribution within a particle filter framework. When an absolute location solution is available, the particle filter provides absolute position updates to an underlying visual SLAM-based navigation system. This architecture allows the visual SLAM navigation solution to take advantage of absolute position information when it is available but continue to provide a relative solution when it is not. All processing is performed onboard the vehicle on a lightweight and powerful computer. For both indoor and outdoor operation, flight test results are presented. The results show very good position tracking and a bounded position variance.
Byzantine Agreement on Mobile Ad-Hoc Network

Mobile Ad Hoc Network (MANET) has been more and more popular. MANET is a self-organizing, self-configuring and instantly deployable multi-hop wireless network in response to application needs without any fixed infrastructure. Moreover, the fault-tolerance and reliability of the MANET has also been an important topic. Toward this goal, we need a mechanism to allow a set of nodes to agree on a common value. The distributed Byzantine Agreement (BA) problem is one of the most important issues to take into consideration in designing a fault-tolerance system. In many cases, reaching a common agreement among fault-free nodes to cope with the influence from faulty components is crucial in a fault-tolerance system. In this study, the BA problem is visited in a MANET, in which the components may be subject to malicious fault.
A Hyperlink-Extended Language Model for Microblog Retrieval

Microblog retrieval has received much attention in recent years. In microblog retrieval, the content linked by URLs is one of the most important information of a microblog. We present a Hyperlink-extended model for microblog retrieval that combines content of microblogs and the content of embedded hyperlinks webpages using a probabilistic ranking function based on language model. Hyperlink-extended language model incorporates the users' information retrieval requirements and the microblog author’s expression needs. Using standard TREC 2011 and TREC 2012 microblog retrieval collection, various aspects of our microblog retrieval model are evaluated. Results show our model significantly outperform the art-of-the-state URL-based approaches and the best performance of TREC 2012 microblog retrieval.
Content-Based Search, and Retrieval of Audio

Many audio and multimedia applications would benefit from the ability to classify and search for audio based on its characteristics. The audio analysis, search, and classification engine described here reduces sounds to perceptual and acoustical features. This lets users search or retrieve sounds by any one feature or a combination of them, by specifying previously learned classes based on these features, or by selecting or entering reference sounds and asking the engine to retrieve similar or dissimilar sounds.
LINEAR PROGRAMMING OPTIMIZATION OF QUERY ALLOCATION IN A DISTRIBUTED CEP SYSTEM

In Fujitsu’s up-and-coming Complex Event Processing service, the servers used for query-storage lie in a cloud environment. The cost of setting up the user-defined systems can therefore immediately be translated into the number of servers that is required and the amount of data that need to be sent between the servers.The objective of this thesis was to provide a model that optimizes the cost of setting up these systems. The problem of query allocation has been modeled a linear program, such that the number of servers needed and the communication between them is minimized.This turns out to be a kind of bin-packing-problem, which is known to be NP hard. Attempts to optimize the execution time were therefore made by implementing a customized solver that combined optimizations based on the problem-specific knowledge with the branch-and-bound-technique generally used by LP (Linear Programming) solvers. The customized solver was then compared to the commonly-used GLPK-solver and the comparison showed that the customized solver was to prefer in realistic scenarios where a lot of servers were needed. The GLPK solver did however often find the optimal solution early on, but could not discard the possibility of better solutions due to symmetry problems. The GLPK solver may therefore also be used if a certain fault-tolerance is acceptable.
Teacher Opinions Regarding the Impact of Educational Software on Reading Skills of First Graders

The purpose of this study is to evaluate teacher opinions on the impact of educational software used for reading instruction. It is designed as a qualitative research. The study group consists of 8 classroom teachers. Data is collected as semi-structured interviews, and analyzed by content analysis. According to the qualitative results of the study, teachers have positive opinion on educational software. Teachers listed the advantages of educational softwares as; they are beneficial to students, draw students' attention, enrich learning environment, support teachers, help saving time, and improves active student participation and access. They mentioned that educational softwares lose their effectiveness when used frequently, caused technical problems, pasify teacher, and open to misuse as some disadvantages. Teachers stated that general difficulties encountered in the process of instructing reading include in the areas of reading comprehension, combining syllables, feeling sounds, hyphenation, creating syllables, erroneous reading, slow reading, and changing sounds based on the letters. For solving these problems, they stated that educational softwares are helpful especially in hyphenation, feeling sounds, correct reading, reading comprehension, and fast reading.
Suspicion in Phishing and Organization Risk

Phishing emails are communications that are sent out in mass and are designed with the goal of obtaining sensitive information, installing malware on a user’s machine, or gaining access to a network. Training users about the dangers of phishing emails is common in organizations, but users will still frequently fall victim to phishing attacks. Organizations may feel that they are doing the necessary actions, such as providing user security training, to mitigate the risk of users’ lack of secure behavior. Organizations are faced with the challenge of the human element; the most undependable and uncontrollable part of an information system. As time has progressed, corporations are beginning to understand that they must put measures and controls into their security IT to mitigate the possible problems that arise from human interaction with IT. This research attempts to explore suspicion as it relates to emails and how-to better train individuals to recognize illegitimate emails.
Bullies, Victims, and Teachers in Japanese Middle Schools

Since the 1980s, school bullying—Ijime—has been a major concern of educational policy in Japan. After mass media attention to student suicides due to Ijime, and following several law suits, the government has urgently requested that schools deal with Ijime. Two further student suicides in 2005 and 2006 led the Ministry of Education, Culture, Sports, Science, and Technology (hereafter Ministry of Education) to organize several conventions to strategize on ways to reduce Ijime. The reports produced from these conventions emphasized a need for greater collaboration between schools and community members (MEXT 2006a; 2007). In addition to these measures, it is also important to understand the roles that may be played by school resources, including teachers. In Japanese schools, homeroom teachers provide guidance for students’ psychological and social development, in addition to academic development. Homeroom teachers spend significant time counseling students, visiting their families, and developing a homeroom community where students feel a sense of belonging. When Ijime occurs in a classroom, the homeroom teacher is mainly responsible for resolving the case. However, despite the potential for homeroom teachers to reduce Ijime, few researchers have examined the relations between students and their homeroom teachers and the consequences of this relation for Ijime. Even less is known about what relationships Ijime victims and bullies have with their other subject teachers. The aim of this article is to help fill this gap in our knowledge. Here we examine three major aspects of student-teacher relationships in Japanese schools: teacher bonding, student guidance, and instructional support. We then analyze the possible association of these relationships with victimization and perpetration of Ijime based on a survey of students in seven middle schools within a single school district. We pose two general research questions. First, what relationship do Ijime victims and bullies have with school teachers? Second, how is the student-teacher relationship associated with victimization and bullying, controlling for student background characteristics
Protocol architecture of high speed TCP/IP service over international ATM network

TCP/IP based data communication is one of the most promising applications in wide area ATM services. However, it is noticed that TCP becomes the throughput bottleneck over an international ATM network with large propagation delay. The major reason for this problem is that TCP performs window based flow control and the maximum value of the window size is limited by 64 kbytes. Against this problem, we proposed a high speed TCP/IP service using a TCP gateway, where a pair of TCP gateways are introduced in international ATM networks, and each of them works as an intermediate system along a TCP connection. They improve the TCP throughput by introducing a link-by-link flow control and a sufficient window size between the gateways, without any modifications to end terminals. In the design of a TCP gateway, we have also taken account of the mechanisms avoiding the performance degradation due to transmission errors and congestion. In this paper, we describe the protocol architecture of the TCP gateway and its performance by comparing with conventional TCP and TCP with window scale option. The results of performance evaluation show that the TCP gateway can provide more than 20 times higher throughput than conventional TCP, and that it can attain higher performance in the sense of throughput and fairness than the case where TCP with window scale option is used in customer terminals.
