Quality of service (qos) provisioning in multihop ad hoc networks

A multihop wireless ad hoc network consists of a number of nodes that form a dynamic topology with ad hoc wireless links among neighboring nodes. These nodes are typically limited in resources such as bandwidth, computation power, memory, and battery. Quality of Service (QoS) is usually defined as a set of service requirements that need to be met by the network while transporting a packet stream from source to destination. With the increasing needs of QoS provisioning for evolving applications such as realtime audio/video, it is desirable to support these services in ad hoc networking environments. This dissertation investigates QoS provisioning techniques for this type of networks. QoS aware routing is an important building block for QoS support. This dissertation first proposes a Positional Attributes based Nexthop Determination Algorithm (PANDA) for flooding based route discovery in wireless ad hoc networks. PANDA has very versatile capabilities and can be used to achieve a variety of routing goals such as shortest hop routing, power conservation routing, and load balancing routing. Mobility models have great impact on the performance of ad hoc routing protocols. This dissertation proposes a Location Aided Knowledge Extraction Routing (LAKER) protocol based on the "Restricted Random Waypoint" mobility model. Complementary to PANDA's efforts in search for better end-to-end routes, the design of LAKER is aimed to reduce flooding overhead by taking advantage of topological characteristics (for example, distribution of population density) of non-uniform net work environments. LAKER learns from past actions to guide future routing process, and as such can narrow the search space and reduce routing overhead. LAKER can also smartly overcome the problem of "void" areas in ad hoc networks. Due to very limited battery resource, energy consumption is tightly integrated with QoS provisioning abilities of the wireless nodes. This dissertation investigates the severe problem of uneven energy consumption rates in wireless sensor networks that have a many-to-one communication model. We develop the "energy hole" model to analyze this problem, and point out the factors that have great impact on energy consumption rates. Based on our model, we study the effectiveness of several approaches towards mitigating the "energy hole" problem, and the simulation results verify our analysis. In multihop networking environments, QoS provisioning needs to satisfy end-to-end requirements. The dissertation proposes an Adaptive Per Hop Differentiation (APHD) scheme towards achieving end-to-end QoS support in multihop wireless net works. APHD scheme incorporates IEEE 802.11e EDCA technique into multihop environments, and it can provide excellent end-to-end delay assurance while achieving much higher network utilization, compared to a pure EDCA scheme.
Covid vaccine dilemma curbing the herd immunity in India- Jab or no jab?

After the devastating second wave of COVID-19, with the rapid increase in the number of new cases in many states of India marking the beginning of a probable third wave of COVID-19, our best bet is taking a jab to protect against COVID-19. Currently, licensed vaccines are found to be reasonably safe and effective. The second wave of COVID-19 was devastating, but it's a silver lining to note that most of the individuals who had taken the jab recovered with mild infections, and the hospitalization rates among jabbed individuals were meager. Various rumours related to the efficacy, safety, content, and side effects of the vaccine in India had caused a plunge in the vaccine acceptance rate leading to hesitancy and carelessness among the Indian population. This is a critical time for facts, not fear or rumors. This review provides an insight into the myths, pros and cons, and efficacy of the available vaccines.
Issues and Management of Islamic Education in a Global Context

The issue of Islamic education management governance in global education is the main objective of this secondary data review. To complete the discussion of this study, we have collected a series of data and literature on several data sources electronically in educational journal publications, book proceedings, and website databases that actively voice Islamic education issues in a global context. We cannot describe the data that we collect directly. We analyze it using various approaches, such as sharp evaluation coding and drawing conclusions that can answer the essence of the problems of this book review. The data we take online is as much as possible to look for the more up-to-date ones published in the last ten years. Finally, we can conclude that based on the findings and discussion data, among others, issues relating to the governance of Islamic religious education still leave problems and challenges, including the difficulty of achieving quality education due to issues of teacher resources that are still low in the mastery of technology that is still lacking. Straightforward access to education is still unequal, and issues related to leadership and school leadership in general education and the Islamic religion. We hope that these results will be a meaningful input in developing studies related to issues and governance of education management that will be held in the future.
The Science of Learning Health Systems: Scoping Review of Empirical Research

Background The development and adoption of a learning health system (LHS) has been proposed as a means to address key challenges facing current and future health care systems. The first review of the LHS literature was conducted 5 years ago, identifying only a small number of published papers that had empirically examined the implementation or testing of an LHS. It is timely to look more closely at the published empirical research and to ask the question, Where are we now? 5 years on from that early LHS review. Objective This study performed a scoping review of empirical research within the LHS domain. Taking an “implementation science” lens, the review aims to map out the empirical research that has been conducted to date, identify limitations, and identify future directions for the field. Methods Two academic databases (PubMed and Scopus) were searched using the terms “learning health* system*” for papers published between January 1, 2016, to January 31, 2021, that had an explicit empirical focus on LHSs. Study information was extracted relevant to the review objective, including each study’s publication details; primary concern or focus; context; design; data type; implementation framework, model, or theory used; and implementation determinants or outcomes examined. Results A total of 76 studies were included in this review. Over two-thirds of the studies were concerned with implementing a particular program, system, or platform (53/76, 69.7%) designed to contribute to achieving an LHS. Most of these studies focused on a particular clinical context or patient population (37/53, 69.8%), with far fewer studies focusing on whole hospital systems (4/53, 7.5%) or on other broad health care systems encompassing multiple facilities (12/53, 22.6%). Over two-thirds of the program-specific studies utilized quantitative methods (37/53, 69.8%), with a smaller number utilizing qualitative methods (10/53, 18.9%) or mixed-methods designs (6/53, 11.3%). The remaining 23 studies were classified into 1 of 3 key areas: ethics, policies, and governance (10/76, 13.2%); stakeholder perspectives of LHSs (5/76, 6.6%); or LHS-specific research strategies and tools (8/76, 10.5%). Overall, relatively few studies were identified that incorporated an implementation science framework. Conclusions Although there has been considerable growth in empirical applications of LHSs within the past 5 years, paralleling the recent emergence of LHS-specific research strategies and tools, there are few high-quality studies. Comprehensive reporting of implementation and evaluation efforts is an important step to moving the LHS field forward. In particular, the routine use of implementation determinant and outcome frameworks will improve the assessment and reporting of barriers, enablers, and implementation outcomes in this field and will enable comparison and identification of trends across studies.
Chest CT findings and experience in 100 COVID19 patients in Mosul city, Iraq

Introduction: Due to lack of PCR kits in our area, as well as the extensive dissemination and peaking of COVID-19 since March 2020, our knowledge as radiologists has become increasingly relevant for recognizing CT patterns in order to diagnose and isolate COVID-19-infected patients. In 100 instances, the investigation began with the most prevalent CT chest abnormalities and the CT severity score index in relation to sex. The goal of this study is to better diagnose COVID-19-related lung injuries, enhance the diagnostic accuracy of chest CT scans, and track disease development in Mosul City. Materials and Methods: From June 2020 to January 2021, one hundred patients were enrolled in this cross-sectional study in Mosul, with 71 males (71%) and 29 females (29%) ranging in age from 15 to 85 years, mean SD (53.2317.80). Non contrast chest CT were done as part of investigation tool on patients were suspected COVID-19 infection. Results: A radiologist gathered data between 4 and 10 days after the onset of symptoms and evaluated it for lesion pattern, location, and severity. The commonest CT changes (ground glass opacity 55.23%, consolidation 17.44%, broncho vascular thickening 9.88%, crazy paving 5.81% and tree in bud 5.23%) were seen, along with less common pattern (bronchiectasis 1.74%, nodules 2.33%, reversed halo sign and pleural effusion 1.17%), and no lymphadenopathy were seen. Multilobe involvement was detected in 52/100 instances (68.92%), while peripheral affection was seen in 52/100 cases (65%). The higher CT severity score 4 and 5 with male gender were found to have a significant link (P value 0.002). Conclusion: CT pulmonary are useful as a physician's helper for management and as an excellent predictor of disease severity and patient outcome. In patients with COVID-19 positive infection, the CT scan severity score is highly linked to laboratory findings, hospital stay, and oxygen demands.
HUMAN-LIKE PRODUCTS : The Effect of 'Facial' Expressions of Different Product Types on Overall Impression and the Need to Build Up Relationship

When designing products, companies and brands sometimes try to employ shapes that are emotionally appealing by anthropomorphizing a product's appearance. The current study focuses on the effect of 'facial' expressions of different product types on overall impression of a product and on the need to build up relationship with, on the one hand, consumer durables and, on the other hand, fast moving consumer goods. It is hypothesized that anthropomorphism has an influence on the overall impression of a product and on the need to build up relationship with a product. Further, it is expected that the need to build up relationship with an anthropomorphized consumer durable is more likely than the need to build up relationship with a FMCG. A 5 (facial expressions) x 2 (product types) experiment was conducted. The results of the study show several significant effects. The study investigated that the need to build up a relationship with an anthropomorphized product does not depend on the product type alone but in fact on the 'facial' expression the product exhibits. Furthermore, it was found that anthropomorphized consumer durables show more positive effects on the present dependent variables when their design contains angry design elements. However, anthropomorphized bottles with mineral water show more positive effects on these variables when their design contains friendly elements. Limitations and implications will be discussed and suggestions for future research are given.

Dynamic analysis for the tether of submerged floating tunnel

The tether of a submerged floating tunnel is taken as a beam subjected to tension,and dynamics and Morison equations are used to set up vortex-induced oscillation equations of the tether.Effects of tether's obliquity,tension and length on its maximal dynamic shearing force and bending moments are discussed.The results show that the decrease of the vertical depth and tension of the tether induce the increase of the maximal dynamic shearing force and bending moment,whereas the decrease of tether's obliquity induces the decrease of the maximal dynamic shearing force and bending moment;the first-order natural frequency of tether is in direct proportion to the tension and obliquity,in inverse proportion to the vertical depth of water.
Guided wave based integrated structural health monitoring and nondestructive evaluation

Damage detection and health monitoring are critical for ensuring the structural safety in various fields, such as aerospace, civil and nuclear engineering. Structural health monitoring (SHM) performs online nondestructive evaluation (NDE) and can predict the structural remaining life through appropriate diagnosis and prognosis technologies. Among various SHM/NDE technologies, guided ultrasonic waves have shown great potential for fast and large area SHM/NDE, due to their sensitivity to small defects and capability to propagate long distances. Recent advances in guided wave based SHM/NDE technologies have demonstrated the feasibility of detecting damage in simple structures such as metallic plates and pipes. However, there remain many challenging tasks for quantifying damage, especially for damage quantification in complex structures such as laminated composites and honeycomb sandwich structures. Moreover, guided wave propagations in complex structures, and wave interactions with various types of defects such as crack, delamination and debonding damage, need to be investigated. The objective of this dissertation research is to develop guided wave based integrated SHM and NDE methodologies for damage detection and quantification in complex structures. This objective is achieved through guided wave modeling, optimized sensor and sensing system development, and quantitative and visualized damage diagnoses. Moreover, the developed SHM/NDE methodologies are used for various damage detection and health monitoring applications.
Flow Control By Pulsed Jet In A Highly Bended S-Duct

This paper presents an experiment of flow control by pulsed jets in an S-duct. One of the novelties of this study comes from the fact that PIV has been employed to characterize the flow in the duct. Specific techniques have been used to deal with optical accesses and particle seeding issues. The Mach number in the Aerodynamic Interface Plane ranges from 0.2 to 0.45. This range is realistic from an application point of view and it has necessitated the design of supersonic pulsed jet actuators. Finally, it is shown that the flow can be fully reattached even in a very aggressive duct. A sensitivity of the distortion coefficient to the jet frequency has been clearly identified. Surprisingly, it is recommended to avoid using natural frequencies present in the separated zone of the uncontrolled flow.
International Journal of Emerging Electric Power Systems Fault Discrimination Using Synchronized Sequence Measurements under Strong White Gaussian Noise

In this paper on strong white Gaussian noise background based on discriminant analysis theory, we mainly adopt synchronized sequence measurements of PMU to search for laws of electrical quantities marked changes. We have developed a method to quickly and accurately discriminate fault components and fault sections. The research has shown that the fault discrimination by discriminant analysis theory is effective and reliable. Under the interference of strong random white Gaussian noise, discriminant analysis still has high redundancy.

A high speed wearable system for body coupled communication

There are currently no ideal methods by which doctors can read bodily signals detected by implanted devices. Methods are either too high power for long-term implants, such as radio transmission, or pose health threats to the patient, such as connection ports piercing the skin. However, a novel method of transmitting and receiving electronic sensor data is emerging known as body coupled communication (BCC). This method of communication utilizes the inside of the body's low impedance at frequencies on the order of 100 MHz to send signals over that channel and receive the signals at another location on the body. It is also a lower power and more secure wireless option than radio transmission. This thesis presents a 3 Mbps wearable receiver and transmitter system for BCC that was developed from commercially available electrical components and a custom PCB. Both receiver and transmitter are on the same PCB. They share a digital FPGA system, but have separate analog signal conditioning sections on the board. Thesis Supervisor: Professor Charles G. Sodini Title: Clarence J. LeBel Professor
STUDY OF EVAPOTRANSPIRATION OVER TELANGANA AND RAYALASEEMA REGIONS FOR THE YEAR 2019

This paper emphasizes the connection of evapotranspiration (ET) with some parameters over Telangana (TN) and Rayalaseema (RAYAL) regions. The parameters which we have utilized to study the ET parameter are rainfall (RF), soil moisture(SM), latent heat flux (LF), sensible heat flux (SF) and temperature (TEMP). The NASA’s Global Land Data Assimilation System (GLDAS -2.1) dataset was utilized in this study during the year 2019. It is a very essential dataset for analyzing the water resources. The Telang ana region is having more ET, SM and RF when compared to Rayalaseema region for 2019. Rainfall has shown 0.80 correlation with ET whereas LF, SM parameters showed 0.93 correlation with ET. ET is having less correlation with temperature when compared to other parameters in this study.
TECHNICAL AND PHYSIOLOGICAL RESPONSES OF SWIMMING CRAWLSTROKE USING HAND PADDLES, FINS AND SNORKEL IN SWIMMING FLUME: A PILOT STUDY

We evaluated the effect on front-crawl during a 5 minutes effort in a swimming flume, at a speed 95% of 400m wearing swimming paddles, fins or frontal snorkel. It was evaluated measuring changes on stroke frequency, stroke length, ERP, lactate concentration and pulse rate post-effort. An one-way repeated measures ANOVA showed the stroke frequency was significantly affected F(2.3, 27.6) = 20.69 p<0.01, the stroke length F(2.67, 32.23) = 21.56 p<0.01, the RPE F(25.5, 36.0) = 14.87 p<0.01, the lactate on 3’ F(2.3, 27.8) = 11.30 p<0.01, the lactate on 5’ F(2.8, 33.5) = 12.80 p<0.01 and the pulse rate F(3, 30) = 4.73 p<0.01. The use of swimming paddles and fins increases the stroke efficiency and reduce the load of the exercise while the use of snorkel did not differ from normal crawl-stroke.
The Effect of a Soccer Tournament on Baseline Psycho-Hormonal States of Collegiate Female Players

Background. Anxiety plays a major role when it comes to sports performance, not only mentally, but physically as well. Objectives. The study aimed to examine the effect of a soccer tournament on baseline anxiety [Spielberger State-trait anxiety inventory questionnaire (STAI), mood [Incredible Short POMS questionnaire (ISP)] and cortisol (saliva sampling) states. Methods. Eight sportswomen’s (age: 23.1 ± 3.2 y, playing experience: 10.6 ± 5.6 y) data were collected an hour after waking, two weeks prior to, and each morning during, a five-day tournament. Results. Overall, a small relationship was seen between true cortisol values and presence of state-anxiety (r = 0.3, P = < 0.05). On mornings prior to a match lost, a significant relationship was seen between cortisol and the current(r = 0.7, P = 0.005) and total trait-anxiety scores (r = 0.7, P = 0.008). Following multiple regression analysis, the TAI questionnaire was demonstrated to be adequate to predict possible cortisol surges (r = 0.3, P = 0.04). Measuring the innate anxiety characteristic can be a positive measure to anticipate both psychological (presence of anxiety, r = 0.88, P = 0.001) and physiological (cortisol surges, r = 0.4, P = 0.008) stress. Conclusion. Therefore, an anxiety questionnaire might provide sensitive information regarding the unconscious physiological and psychological stress plausibly altering performance. It is recommended that a player’s state of anxiety (innate and current) be measured prior to a competition to adopt a strategy to overcome its negative consequences.
Willingness to Pay for Ecosystem Services among Stakeholder Groups in a South-Central U.S. Watershed with Regional Conflict

AbstractEcosystem services valuation has become a popular approach to weighing trade-offs in environmental management, particularly where natural resources such as freshwater are limited. The authors assessed multiple stakeholders’ social perception regarding a suite of ecosystem services in a south-central U.S. watershed that is water stressed and experiencing intense sociopolitical conflict. First, the ecosystem service beneficiaries were identified and characterized according to how they use and value ecosystem services. Second, the factors underlying social importance and economic support for maintaining these ecosystem services were analyzed. Finally, a willingness to pay approach was used to identify the economic value of services and explored potential biases in water management based on social and cultural attributes. Results (1) identified habitat for species and water quality as the most important and economically valuable ecosystem services, respectively, and (2) uncovered potential conflicts b.
