Health monitoring of a historical monument in Jordan based on ambient vibration test

Bani-Hani, Khaldoon A.,Zibdeh, Hazem S.,Hamdaoui, Karim Techno-Press 2008 Smart Structures and Systems, An International Jou Vol.4 No.2

This paper summarizes the experimental vibration-based structural health monitoring study on a historical monument in Jordan. In this work, and within the framework of the European Commission funded project "wide-Range Non-Intrusive Devices Toward Conservation of Historical Monuments in the Mediterranean Area", a seven and a half century old minaret located in Ajloun (73 km north of the capital Amman) is studied. Because of their cultural value, touristic importance and the desire to preserve them for the future, only non-destructive tests were allowed for the experimental investigation of such heritage structures. Therefore, after dimensional measurements and determination of the current state of damage in the selected monument, ambient vibration tests are conducted to measure the accelerations at strategic locations of the system. Output-only modal identification technique is applied to extract the modal parameters such as natural frequencies and mode shapes. A Non-linear version of SAP 2000 computer program is used to develop a three-dimensional finite element model of the minaret. The developed numerical model is then updated according to the modal parameters obtained experimentally by the ambient-vibration test-results and the measured characteristics of old stone and deteriorated mortar. Moreover, a parametric identification method using the N4Sid state space model is employed to model the dynamic behavior of the minaret and to build up a robust, immune and noise tolerant model.

Muntaha Suliman,Hani Bani-Salameh,Adel Saif 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.3

This paper presents an approach to visualize communication among developers during development. The proposed approach analyzes and visualizes various types of communication flows between developers. The main focus of this approach is on emails, chat archives, bugs and common files extracted from version histories and public communication archives. A tool is developed to realize the approach, VCSD, (Visualizing Communication between Software Developers). The tool provides three views that present the overall different and useful aspects for collaborations. Project managers can get a comprehensive understanding about collaborations between developers as well as contributions of each developer and how they are involved in the development process. The main components are menu bar, three graphical views and the timeline. First view presents the communication evolution. Second view presents system’s evolution and third view presents the modification history.

Al-Muqbel, Kusai M.,Bani Hani, Mohammed N.,Elheis, Mwaffaq A.,Al-Omari, Ma'moon H. The Korea Society of Nuclear Medicine 2010 핵의학 분자영상 Vol.44 No.4

Purpose There are conflicting data in the literature regarding the reproducibility of the gallbladder ejection fraction (GBEF) measured by fatty meal cholescintigraphy (CS). We aimed to test the reproducibility of GBEF measured by fatty meal CS. Methods Thirty-five subjects (25 healthy volunteers and 10 patients with chronic abdominal pain) underwent fatty meal CS twice in order to measure GBEF1 and GBEF2. The healthy volunteers underwent a repeat scan within 1-13 months from the first scan. The patients underwent a repeat scan within 1-4 years from the first scan and were not found to have chronic acalculous cholecystitis (CAC). Our standard fatty meal was composed of a 60-g Snickers chocolate bar and 200 ml full-fat yogurt. Results The mean ${\pm}$ SD values for GBEF1 and GBEF2 were $52{\pm}17%$ and $52{\pm}16%$, respectively. There was a direct linear correlation between the values of GBEF1 and GBEF2 for the subjects, with a correlation coefficient of 0.509 (p=0.002). Subgroup data analysis of the volunteer group showed that there was significant linear correlation between volunteer values of GBEF1 and GBEF2, with a correlation coefficient of 0.473 (p=0.017). Subgroup data analysis of the non-CAC patient group showed no significant correlation between patient values of GBEF1 and GBEF2, likely due to limited sample size. Conclusions This study showed that fatty meal CS is a reliable test in gallbladder motility evaluation and that GBEF measured by fatty meal CS is reproducible.

Jamming Resilient Multi-Channel Transmission for Cognitive Radio IoT-based Medical Networks

Khadr, Monette,Salameh, Haythem Bany,Ayyash, Moussa S.,Elgala, Hany,Almajali, Sufyan 한국통신학회 2022 Journal of communications and networks Vol.24 No.6

The era of the Internet-of-things (IoT) comes withtremendous burdens on pre-existing network infrastructures andprotocols due to spectrum scarcity and reliability concerns. Cognitive radio (CR) technology is proposed for IoT applica-tions to alleviate the spectrum scarcity paradigm. In CR-IoT-based networks, the IoT devices/nodes share the spectrum withprimary users (PUs). However, in order not to interfere with PUscommunications and to conform with the elevating throughputrequirements, efficient multi-radio/multi-channel assignment al-gorithms are required. Additionally, in order to ensure reliabletransmission, algorithms need to be resilient to jamming attacks,which have detrimental impacts on network performance. In thispaper, parallel-channel security-aware medium access control(PCS-MAC) is proposed as a probabilistic-based jamming re-silient multi-channel assignment algorithm proposed for medicalnetworks. PCS-MAC considers primary user activity, channelconditions, jamming attack levels, and data-rate requirementsto provide spectrally efficient data transmission between CR-IoT nodes subject to delay constraints under jamming attacks toassure the delivery of time-critical patient data. The performanceof PCS-MAC is practically validated using the open large-scalefuture Internet-of-things (FIT) IoT-LAB testbed. Practical resultsshow that our proposed algorithm significantly enhances networkperformance, yielding throughput rates that supersedes the state-of-the-art algorithms presented in literature.

Purpose: To report rates of and reasons for operation cancellation, and to prioritize areas of improvement. Methods: Retrospective data were extracted from the monthly reports of cancelled listed operations. Data on 14 theatres were collected by the office of quality assurance at Jordan University Hospital from August 2012 to April 2016. Rates and reasons for operation cancellation were investigated. A Pareto chart was constructed to identify the reasons of highest priority. Results: During the period of study, 6,431 cases (9.31%) were cancelled out of 69,066 listed cases. Patient no-shows accounted for 62.52% of cancellations. A Pareto analysis showed that around 80% of the known reasons for cancellation after admission were due to a lack of surgical theatre time (30%), incomplete preoperative assessment (21%), upper respiratory tract infection (19%), and high blood pressure (13%). Conclusion: This study identified the most common reasons for operation cancellation at a teaching hospital. Potential avoidable root causes and recommended interventions were suggested accordingly. Future research, available resources, hospital policies, and strategic measures directed to tackle these reasons should take priority.

Mohammed A. Al-Ghazo,Ibrahim Fathi Ghalayini,Rami Al-Azab,Osama Bani Hani,Yousef S. Matani,Yazan Haddad 대한배뇨장애요실금학회 2011 International Neurourology Journal Vol.15 No.1

Purpose: To evaluate the relationship between urodynamic detrusor overactivity (DO) and overactive bladder (OAB) symptoms in men and women. Methods: We reviewed the records of adult males and females who attended a tertiary referral center for urodynamic evaluation of OAB syndrome symptoms with the presence or absence of DO. DO was calculated for symptoms alone or in combination. Results: The overall incidence of DO was 76.1% and 58.7% in male and female OAB patients, respectively. Of men 63% and 61% of women with urgency (OAB dry) had DO, while 93% of men and 69.8% of women with urgency and urgency urinary incontinence (OAB wet) had DO. Of women, 58% who were OAB wet had stress urinary incontinence symptoms with 26.4% having urodynamic stress incontinence. 6% of men and 6.5% of women with OAB symptoms had urodynamic diagnosis of voiding difficulties with postvoid residual greater than 100 mL. Combination of symptoms is more accurate in predicting DO in OAB patients. The multivariate disease model for males included urge urinary incontinence (UUI) and urgency while for females it included UUI and nocturia. Conclusions: There was a better correlation in results between OAB symptoms and the urodynamic diagnosis of DO in men than in women, more so in OAB wet than in OAB dry. Combination of symptoms of the OAB syndrome seems to have a better correlation with objective parameters from the bladder diary, filling cystometry, and with the occurrence of DO.
