Noise mitigation strategies for vacuum excavators
Authors: Yoerg Keith , McKenna Shannon
Published: July 2022

Vacuum Excavators (Vac-truck/Hydrovac) are among the loudest pieces of equipment used during certain construction activities and are often required to run for extended periods of time. Noise from these trucks has the potential to exceed acceptable levels when operating close to sensitive
receivers, particularly in dense urban areas. The noise generated by vac-trucks presents several options for unique mitigation strategies to reduce the impact to nearby noise sensitive receivers. Careful selection and preconstruction noise measurements of equipment, placement of noise blankets
around each noise source, and orienting the truck to take advantage of noise shielding from nearby buildings or to direct the loudest side of the truck away from sensitive receivers can all help reduce the impact of noise to the surrounding communities.
An experimental study of flow-induced noise from perforated pipes
Authors: Donkin Seth , Herrin David
Published: July 2022

An experimental study was performed to understand the generated flow noise by perforated pipes inside of concentric tube resonators. Six perforated pipes with 2% to 45% open areas and hole diameters ranging from 0.8 mm to 4.65 mm are considered. The six concentric tube resonators are
compared to a straight pipe and a simple expansion chamber. All cases are tested at ten flow velocities ranging from 0.1 Mach to 0.28 Mach with a 0.02 Mach increment. The effect of the hole diameter and perforation rate on the noise generation and the overall level of the radiated noise is
examined. It is found that the whistle frequency is inversely proportional to the hole diameter and proportional to the flow velocity. The amplitude of the generated flow noise is proportional to the perforation rate. Finally, an insertion loss method is used to demonstrate that minimizing
the hole diameter and perforation rate decreases the generated flow noise.
Quantification of the noise control benefit realized by installing an aerodynamic fairing to a passenger vehicle
Authors: Hemme Dan
Published: July 2022

The purpose of this study is to quantify the reduction of cabin noise inside a vehicle due the installation of an aerodynamic fairing to the cargo rack to the roof of the vehicle. Sound level measurements were taken inside the vehicle with and without the fairing installed, and with
and without the sunroof open, over a variety of vehicle speeds. The measurement results are compared on a one-third-octave-band basis, in terms of A-weighted decibels, and in terms of Speech Intelligibility Index ratings.

Authors: Yazbec Edwin , Specht Matt , Kiefer Dylan , Harrington Ryan , Marchi Jacob , Girdhar Sunit , DeClerk Dr. James , Barnard Dr. Andrew
Published: July 2022

Impact testing has been in use since 1927 for acoustic testing of floor ceiling assemblies. The process used in the United States is defined in the ASTM E1007 standard. This testing method produces an Impact Sound Rating (ISR) which is a measure of the impact sound isolation between
an upper and lower room and is used in industry for assessment and comparison of constructions. A standard tapping machine is used to generate an input force. The intent is to deliver a consistent input across all floors; however, the actual input force is dependent on the impedance of the
impact device and floor. A soft floor may have a significantly different force than a hard floor. This variance is not accounted for when computing the ISR, resulting in less meaningful test results. This paper investigates an alternative method of impact force generation though the creation
of a machine purpose built to measure the input force on any type of floor ceiling assembly. Measurement of the input force would allow for FRF calculations which may be a more informative method of sound isolation evaluation.
Testing listeners' ability to localize virtual sources using sparse loudspeaker arrays and comparison with spherical-head model predictions
Authors: Wells Nathaniel , Sanders Tyler , Sommerfeldt Scott , Jonathan Blotter
Published: July 2022

Virtual acoustic environments are created by mimicking pressures of real acoustic sources at the ears of a listener. One method to control these pressures is through the use of loudspeaker arrays. While the best results come from arrays with a large number of loudspeakers, they are
not practical for everyday use. On the other hand, sparse loudspeaker arrays are physically limited by the listener's localization ability and the sensitivity to head translation and rotation. Previously a model was created to find the limits of each of these features for a spherical head
in a free-field environment. Subsequently the loudspeaker locations were optimized based on these features. Listening tests were carried out to find the limits of these features for a variety of loudspeaker array configurations. These tests were carried out in an anechoic chamber with the
loudspeaker locations hidden by acoustically transparent curtains. The localization ability for each configuration was recorded. This was repeated for deviations from the optimal listener location in both head rotation and translation. The results were compared to the free-field model previously
established.
Noise metrics of the time-varying acoustic far-field of rotors
Authors: Baars Woutijn , Grande Edoardo , Ragni Daniele
Published: July 2022

Rotor noise comprises harmonic features, related to the blade passing frequency, as well as broadband noise. Even though an acoustic spectrum yields a frequency-distribution of energy within an acoustic pressure signal, it does not reveal phase-relations between different frequency
components. The latter are of critical importance for the development of accurate prediction- and auralization-algorithms, because they may result in low-frequency modulation: temporal variations in the intensity of higher-frequency rotor noise. Baars et al. recently outlined a methodology
to quantify inter-frequency modulation. The current work applies this methodology to a new and comprehensive dataset of a laboratory-scale rotor at advance ratios ranging from J = 0 to 0.6. PIV measurements of the blade-induced flow disturbances complement the acoustic data to elucidate how
the vortical flow structures of one blade impact the inflow of the consecutive blade. Findings of the directivity patterns of modulation are described and interpreted using existing knowledge of the specific noise sources of the low Reynolds number (small-scale) rotor.
Simulation of perforations using distance-based linearized navier-stokes-fourier
Authors: Yan Xin , Herrin David , Ghaisas Nikhil
Published: July 2022

MPP absorbers are used in many applications including auditoria, barriers, and mufflers. Sound is absorbed due to viscous friction in the small perforations. The 2D FEM method is used to model small tubes in Actran. The objective of this work is to model different perforation geometries,
hole diameters and the perforation rates to better understand how the shape and rate of the perforation affect the MPP properties. In addition, we are also performing this work to better understand and evaluate small channel modeling capabilities in Actran.
Computational investigation into the effect of material properties on aeroacoustics based damage detection from wind turbine blades
Authors: Traylor Caleb , Inalpolat Murat
Published: July 2022

A wind turbine blade monitoring system would provide significant benefit to wind farm owners and operators by reducing operation and maintenance costs and increasing energy production by limiting turbine downtime. Previous work has demonstrated potential success of a system based on
monitoring the flow-generated sound with blade internal cavity microphones. In this study, the effect of blade material acoustic properties is investigated to provide recommendations on the potential application of this approach. A reduced-order model is used to identify the flow-generated
lumped-parameter acoustic sources outside the blade at a frequency of 10 kHz. A feasible range of acoustic properties is used for the blade and shear web acoustic transmission coefficient and acoustic reflection coefficient. Damage detection success improved as reflection increased, as more
sound propagated toward to the root of the blade. However, the damage detection success rate did not consistently increase with an increase or decrease in the transmission coefficient and balance must be achieved depending on the specific blade and the expected flow-generated sound. These
results demonstrate the usefulness of quantifying the blade material acoustic properties and will be used to strategically design a blade monitoring system.
Finding damping loss factor using circle-fit method on Nyquist diagrams.
Authors: De Alba Alvarez Ricardo , Kelly Malcolm , Hale Colin , Marinelli Pete
Published: July 2022

Viscoelastic materials are commonly applied into vehicles sheet metal structures including the roof and doors in order to increase the amount of structural damping. The added damping from viscoelastic materials dissipates a greater amount of vibrational energy, subsequently reducing
vibration displacement, structure borne noise, and energy flow to adjacent structures. Because damping treatments have the disadvantage of adding weight to the treated structure, adequate tools to characterize and evaluate their efficiency are necessary. In this paper, natural frequencies
and modal damping are determined by applying circle-fit interpolation to measured data. Comparison to traditional peak picking and half-power point methods shows that this geometric approach allows modal frequencies to be identified more clearly, even for measurement systems with reduced frequency
resolution and the process can be easily automated.
Quantitative comparisons of resilient channel designs in walls and ceilings
Authors: Dong Wayland , LoVerde John
Published: July 2022

Resilient channel is common within lightweight construction to improve the airborne and impact noise isolation of wall and floor-ceiling assemblies. The authors have previously presented results from systematic studies of resilient channels in wood stud wall assemblies (Internoise 2009;
International Congress on Acoustics 2010) and wood-joist floor assemblies (International Congress on Sound and Vibration 2015) in which the effect of brand and model of resilient channel was compared in various assemblies. These studies documented the clear and significant acoustical performance
differences between makes and models of channel that would have been considered equivalent before the release of this work. Additional comparative studies have been performed adding to the data previously presented. Acoustical performance is compared and conclusions about products are presented.
Review of concepts relating to measurement quality
Authors: Dick Elliott
Published: July 2022

Misconceptions about measurements and measurement quality persist even among otherwise highly competent acoustical and noise-control professionals. There are many related but different concepts to describe measurement quality, including precision, accuracy, bias, uncertainty, resolution,
and significant figures. These concepts apply to reporting a measurement result, to characterization of test methods, to evaluation against a specification, and to criteria for development of both test methods and specifications. The field of acoustics and noise control attracts professionals
with a broad range of backgrounds, and therefore not all are versed in exactly what a measurement result means, or the difference in these measurement quality concepts. This is further compounded by the fact that many times acoustic tests are used in legal contexts, either for code compliance
or in legal disputes. The law wants to work with black-and-white concepts, but all measurements inherently have some grey areas. Proper understanding begins by acknowledging that the answer yielded by a measurement is not the correct answer, not the true value of the measurand, but something
close to it (very close if high quality). The various concepts of measurement quality are all ways to assess the test method and the results yielded from the test method.
Case study: Compilation of doorwall designs for speech privacy
Authors: Rosentel William , Holst Peter
Published: July 2022

A common complaint in offices is meetings within enclosed rooms disrupting nearby open workstations or poor speech privacy to circulation corridors. In this scenario, occupant satisfaction depends on multiple factors, including sound isolation of the wall, door, glazing, and the background
noise levels. Using experience from several projects with collected measurement data, this presentation will review various door-wall design scenarios with post-construction testing results and conditions where day-two improvements were implemented to meet client standards. The limiting factor
in sound isolation performance is often the door gaskets. Aluminum frames are commonly manufactured with integrated gaskets, which can be a cost-effective contractor replacement. However, these gaskets tend to be smaller than the typical recommended perimeter types and have been observed to
form inconsistent seals once doors are installed. Floor transition strips for dropping bottom seals are another frequent coordination issue. Outside the enclosed room, coordination of the mechanical design and architectural ceiling choice should be used to define the appropriate corridor partition
design to achieve acceptable outcomes. Where client standards and performance rating systems such as LEED and WELL define sound isolation criteria for corridor walls, a well-coordinated acoustical design is critical for achieving the credit objectives.
Additive manufacturing of ceramic porous structures for acoustical applications
Authors: Nevarez-Saenz David , Adler Ted , Wei Wei , Sharma Bhisham
Published: July 2022

Ceramics offer the unique ability to withstand extreme temperatures and pressures without mechanical degradation-characteristics that make them ideal for acoustic applications in extreme environments. While ceramic forming is now a mature technology, traditional forming methods only
allow two-dimensional design freedom, cannot create internal features, and often require expensive dies. Here, we propose the use of additive manufacturing (AM) to fabricate porous structures with complex pore geometries suitable for noise reduction applications. We fabricate cylindrical impedance
tube test coupons of various pore geometries using a robocasting method that relies on clay extrusion. The printed green bodies are fired and sintered in an automated kiln to obtain the final ceramic sample. In this paper, we present the preliminary results from our wok on characterizing the
relationships between the ceramic AM process parameters and the final ceramic part quality and dimensional accuracy. Finally, we investigate the acoustic absorption characteristics of the printed coupons using the normal incidence two microphone impedance tube method. Our results show that
ceramics AM provides an attractive route to fabricate complex acoustic structures suitable for high temperature environments.
Compilation of restaurant acoustics data logged in Omaha, Nebraska
Authors: Underwood Samuel , Wang Lily
Published: July 2022

The high levels of noise in many restaurants continue to be a source of discomfort and complaints for customers. A measurement campaign of local occupied restaurants has been underway at the University of Nebraska since 2019, to gather data towards understanding how owners and acoustical
consultants can better design restaurant sound fields. A review of the results obtained to date is presented, including the sound levels experienced in a restaurant over the course of an evening, those levels compared to occupancy, octave band distributions, statistical levels, how levels
change at different locations in a restaurant, and the percent of time that levels in the restaurant exceed 70 dB. One goal in the project is to link the measured objective data to subjective responses of the occupants. Progress on that goal is also discussed in this presentation.
Preliminary evaluation of transportation noise masking of UAV Noise
Authors: Rochat Judith , Singleton Herbert , Yoerg Keith
Published: July 2022

Unmanned aerial vehicles (UAVs) and unmanned mobility vehicles (UAMs) can be used for many purposes, ranging from package delivery to transporting people. Flight paths for these vehicles may be over or near transportation corridors. Communities near these corridors may be exposed to
a type of noise not currently experienced, with current noise sources typically related to aircraft, rail, and road operations. This paper focuses on audibility of UAV noise in the presence of transportation noise, specifically highway traffic noise with varying parameters, including pavement
type, percentage of heavy trucks, noise wall, and distance from the highway. Noise data from a single UAV event and multiple highway noise measurements are used to explore potential masking and audibility.
Measurement and characterization of multirotor unmanned aerial system noise
Authors: Greenwood Eric , Konzel N. Blaise
Published: July 2022

The acoustic flight test and data analysis procedures developed for the reliable characterization of noise from multirotor Unmanned Aerial Systems (UAS) are described. In contrast to conventional aircraft, multirotor UAS provide a unique challenge due to their small size and sensitivity
to disturbances, the use of fixed-pitch variable speed rotors, and of multiple electric motors to provide both propulsion and flight control. In combination, these factors lead to increased variability in the magnitude and directionality of the radiated noise. UAS acoustic flight test procedures
are developed to quantify the variability in UAS noise across a range of flight conditions, including flyovers, hovering flight, approach and ascent. These procedures are applied to collect and analyze an extensive set of acoustic flight test data for a multirotor UAS. Some representative
acoustic data are presented, showing typical variations in measured acoustic characteristics. These data will be used to develop guidelines for the repeatable characterization of UAS noise.
Mitigation assessment of complex noise sources - an acoustical camera approach
Authors: Pendyala Samuel , Poling Jacob
Published: July 2022

A complex noise source is a set of multiple noise sources operating in proximity. Segregation of individual sub-sources based on sound characteristics and loudness is often the goal but can be challenging. This case study presents one such complex noise source, a high-speed offset printer
in a large-scale printing facility. This printer is an assembly of several modules spanning approximately 40 feet in length. The sound field in the printer area was complex because of many mechanical components propagating sound through air (air-borne), through equipment casing (structure-borne),
and acoustical reflections from nearby surfaces. Localization of dominant sources is required to adequately design mitigation. To identify sub-sources a sophisticated acoustical camera was used for this study. An acoustical camera (SoundCam) is an advanced acoustical measurement device with
an array of 64 microphones and an optical camera. The acoustic signals from the microphones are processed and visualized as sound levels contours in real-time as an optical image or video. Visualization of printer sound levels helped to identify dominant sub-sources and areas of sound reflection.
Once the dominant sub-sources were identified, the sound levels were measured. This helped in developing targeted noise controls in comparatively short duration for a complex noise source.
Novel approach to noise mitigation: a case study demonstrating a collaborative approach between noise consultant and noise solution supplier for economical and practical implementation
Authors: Rajasekaran Jagannath
Published: July 2022

Noise is a nuisance that needs to be addressed. With noise-related government ordinances becoming better defined and more stringently enforced, owners are being forced to address acoustical performance issues far more frequently then ever before. The acoustical design process has a
long history of fragmentation, as there is minimal collaborative design that tends to occur between consultants and implementers (i.e., noise control suppliers and installers). Furthermore, the acoustical design process is often rushed through reactive planning and/or lack of budget. Both
issues can result in downstream performance issues and unforeseen project cost risk. Combining the expertise of both the consultant and the supplier, has proven to dramatically reduce both cost risk and scheduling risk to owners and project stakeholders when sound attenuation is required.
This paper demonstrates the benefits of a collaborative relationship between noise consultants and vendors through a case study. The outcome of this approach will show a positive result for all parties involved: owner, consultant, and vendor. The client benefits from the cost savings, schedule
compression, and limited impacts to facility operations. The acoustic consultant gains the ability to complete more thorough analysis. The acoustic vendors can capitalize on mitigating project risk and streamlining the final solution.
Verification of sound modeling results for a wind energy project
Authors: O'Neal Robert , Bastasch Mark , Cyr Clint
Published: July 2022

As part of a state-level approval process for a wind farm retrofit, both pre-construction sound level modeling, and a post-construction sound level measurement program were developed and executed. The results of the detailed sound level modeling analysis found that low noise blades
were required on some wind turbines to meet the sound level limits at the closest residences. Several scenarios were modeled in order to determine which locations required the low noise blades. Following the retrofit, continuous operational sound level measurements were collected over two
weeks at some of the closest residences to the wind turbines. The results of the monitoring program showed that sound levels from the turbines were in compliance with the state sound limits, and in very good agreement with the pre-construction sound level modeling.

Road noise is one of the dominant contributions to a vehicle interior noise when driving below highway speed. In this paper, we present the process we developed to support automotive OEMs with road noise engineering during vehicle design and development. The process allows to auralize,
in a driving simulator for NVH, road noise CAE simulation results obtained from coupled multibody, structural finite-elements and acoustic models. With this process, engineers can now listen to a vehicle sound and perform interactive sound quality evaluation for road noise even before physical
prototypes are available.
Delivery of Active Medical Management without Dialysis through an Embedded Kidney Palliative Care Model
Authors: Bursic Alexandra E. , Schell Jane O. , Ernecoff Natalie C. , Bansal Amar D.
Published: July 2022

Key Points

Integrating palliative care into kidney care can lead to improvements in symptom management, advance care planning, and hospice utilization.

An embedded kidney palliative care model can enable delivery of active medical management without dialysis to patients whose values align with forgoing dialysis.

Background

Patients with CKD have high symptom burden, low rates of advance care planning (ACP), and frequently receive care that is not goal concordant. Improved integration of palliative care into nephrology and access to active medical management without dialysis (AMMWD) have the potential to improve outcomes through better symptom management and enhanced shared decision making.

Methods

We describe the development of a kidney palliative care (KPC) clinic and how palliative care practices are integrated within an academic nephrology clinic. We performed a retrospective electronic health record (EHR) review for patients seen in this clinic between January 2015 and February 2019 to describe key clinical activities and delivery of AMMWD.

Results

A total of 165 patients were seen in the KPC clinic (139 with CKD and 26 who were already receiving dialysis). Fatigue, mobility issues, and pain were the three most prevalent symptoms (85%, 66%, 58%, respectively). Ninety-one percent of patients had a surrogate decision maker documented in the EHR; 87% of patients had a goals-of-care conversation documented in the EHR. Of the 139 patients with CKD, 67 (48%) chose AMMWD as their disease progressed. Sixty-eight percent (41 of 60) of patients who died during the study were referred to hospice.

Conclusions

Our findings suggest that the integration of palliative care into nephrology can assist in identification of symptoms, lead to high rates of ACP, and provide a mechanism for patients to choose and receive AMMWD. The percentage of patients choosing AMMWD in our study suggests that increased shared decision making may lower rates of dialysis initiation in the United States. Additional prospective research and registries for assessing the effects of AMMWD have the potential to improve care for people living with CKD.
RUSSIA IN THE EUROPEAN OIL MARKET: CHANGES IN THE INTERACTION MODEL
Authors: Kozlova E. , Shibina V.
Published: July 2022

It is expected that the fulfillment of obligations under the Paris Climate Agreement (2015) by 2035 will lead to a sharp drop in global oil demand. However, today, for the countries of the European Union (EU), the shortage of energy carriers and the high dependence in their supply from external sources, especially from Russia, continues to be a serious problem. The purpose of the study is to consider changes in demand for Russian crude oil from the countries of the European Union (EU) and other European countries in the first half of 2022. The main factors determining the dynamics of the world oil market in recent decades are analyzed. The contribution of crude oil imports from Russia to the EU countries to meet their needs for fossil fuel sources, as well as to form the revenue side of the Russian budget in 2019-2021 has been determined. The regions of European countries with an increased demand for petroleum products have been identified. The level of dependence of different countries within the EU on the import of Russian oil is considered. The role of tanker and pipeline transport in the supply of Russian crude oil to the countries of Western Europe is revealed. For Russia, the export of fuel and energy resources is a geopolitical factor of power in the international system. Therefore, the narrowing of its positions in the traditional European energy markets with the introduction by the EU and UK authorities of an embargo on Russian oil prices necessitates both changes in the existing oil transportation strategies to European consumers and the active development of new niches in other external energy markets.

Eski Anadolu Türkçesi Dönemine Ait Bir Eser: Dâsitân-ı Cümcüme Sultân [06 Mil Yz A 9991/2]
Authors: KORKMAZ BULUT Türkan , KORKMAZ Şenol
Published: July 2022

The story of Cimcime Sultan is an old folk tale from the Islamic period of Turkish Literature, written in verse form. The story is based on a conversation between Jesus and a skull, Cümcüme Sultan, whom Jesus encounters when he walks on his way. In the story, Jesus asks guiding questions, and Cimcime Sultan tells what he lived in the world and after he died, in his grave and hell. The work has a didactic feature. In the story, the idea is that this world is temporary and the eternal and permanent one is the afterlife accordingly, death can knock on our door when we least expect it, and we must be prepared before we die. The way to do this is to follow the path of Allah and Allah’s prophet - in this story, Jesus. In the story, the transience of worldly life is told in an instructive way by telling the experiences of Cümcüme Sultan, who has everything to be owned in the world, has thousands of soldiers and employees in his entourage, and has no enemies. In this study, transcription of the text, in-language translation, and index of the work will be given and the story will be examined in terms of both literary and linguistic features.

FOUR LENSES ON PEOPLE MANAGEMENT IN THE PUBLIC SECTOR
Authors: Jore Ali Aisha , Fuenzalida Javier , Gómez Margarita , Williams Martin
Published: July 2022

We review the literature on people management and performance in organisations across a range of disciplines, identifying aspects of management where there is clear evidence about what works as well as aspects where the evidence is mixed or does not yet exist. We organise our discussion by four lenses, or levels of analysis, through which people management can be viewed: (i) individual extrinsic, intrinsic, and psychological factors; (ii) organisational people management, operational management, and culture; (iii) team mechanisms, composition and structural features; and (iv) relationships, including networks, leadership, and individuals’ relationships to their job and tasks. Each of these four lenses corresponds not only to a body of literature but also to a set of management tools and approaches to improving public employees’ performance; articulating the connections across these perspectives is an essential frontier for research. We find that existing people management evidence and practice have overemphasised formal management tools and financial motivations at the expense of understanding how to leverage a broader range of motivations, build organisational culture, and use informal and relational management practices. We suggest that foregrounding the role of relationships in linking people and performance – relational public management – may prove a fertile and interdisciplinary frontier for research and practices.

Managing employees' well-being has garnered the attention of academics and industry practitioners worldwide over the past few years. Presenteeism, a phenomenon that is closely related to employee well-being, has attracted increasing interest in recent years. However, most studies were focused on sickness presenteeism. Hence, in terms of novelty, this study endeavors to examine stress-related presenteeism and its impact on Malaysian employees. In addition, this study also examines team efficacy as one of the determinants of stress presenteeism, which is not widely studied, especially in the Malaysian context. In this study, stress-related presenteeism was utilized to measure presenteeism. Stress-related presenteeism negatively impacts employees' well-being and proves to be costly to employers, as it would lead to lower levels of productivity and performance. The central aim of this study is to examine the determinants of workplace presenteeism through the lens of job demands-resources model. Using Structural Equation Modelling via SmartPLS, the study then proceeds to analyze the consequence of presenteeism on employees' work performance and well-being. The result indicated that workload significantly influences presenteeism and, in turn, leads to lower work performance and psychological well-being. Finally, the implications of these findings were also discussed in this study.

This article aims to explore blockchain, its applications, and its impact on banks in Jordan. The potential applications and improvements that blockchain might bring to the financial industry are astounding. Specifically, this study discussed the importance and possible areas of deploying blockchain technology in the banking sector of an emerging country with a fast-growing economy, namely Jordan, for different reasons. First, due to the shrinking interest-rate spread, Jordan's financial sector lacks long-term lending and unsecured loans. Second, many economic revolutions, such as the internet and banking innovations, have impacted the Jordanian banking sector. As a result, the banking sector must undergo significant transformation to increase performance and attain new levels of growth. Third, the underlying technology in clearing payment and credit bank information systems could be revolutionized by blockchains. Fourth, blockchain applications facilitate "obtain credit, unsecured loans" scenarios, improving banking efficiency. Finally, while blockchain has much appeal because it allows free and self-governing transfers, overall regulation and security for this decentralized system are still being created and agreed upon. We argue that for blockchain to change Jordan's financial system, legal frameworks must be in place to control banking transactions. This study explores the technology of blockchain, the emerging technology that powers Bitcoin and other cryptocurrencies. It highlights the features of the blockchain and shows why it could profoundly influence the entire banking sector in areas ranging from payments to settlements and identity services.

Prior studies have highlighted the impact of electronic word-of-mouth (e-WOM) communication on s-commerce adoption behavior and its important role in helping s-commerce users sustain continuous participation. Despite empirical support, users continue to switch between s-commerce platforms at a high rate despite being actively engaged in e-WOM communication. Hence, the goal of this study is to better understand the mediating influence of trust and commitment on e-WOM communication and continuous-use behavior. This study adopts commitment-trust theory as its underpinning theoretical basis to prove this hypothesis. Data were collected using a web survey technique and analyzed using SmartPLS. The findings of this study demonstrate that trust and commitment significantly mediate the relationship between the 1) perceived utility of e-WOM and continuous intention and 2) perceived enjoyment of e-WOM and continuous intention. This study scientifically proves that a user’s decision to continuously use a s-commerce platform and actively engage in e-WOM activities is mediated by the positive commitment and trust they have toward the s-commerce platform.

It is necessary to verify the state of blood vessel network in the retina for diagnosing various issues associated with eyes. In this research paper, an involuntary retinal vessel segmentation using mathematical morphology is proposed. The contrast of the retinal images is enhanced by contrast limited adaptive histogram equalisation technique. Ten blood vessels of the enhanced retinal image are detected using morphological processing. The hysteresis thresholding is applied on the blood vessels detected image to remove the unwanted back ground detail. Finally the properly segmented binary image of the retinal vessel is obtained using post processing process. Results of the presented method are verified by using most widely used for benchmarking retinal image databases such as, Child Heart and Health Study in England (CHASE_DB1) and Digital Retinal Images for Vessel Extraction (DRIVE) database by computing the evaluation metrics such as sensitivity, specificity, accuracy and precision. The better evaluation metrics achieved for the DRIVE dataset are 0.7493, 0.9687, 0.9524 and 0.6590, and the worst values are 0.6621, 0.9411, 0.9137 and 0.5491. The best evaluation metrics values for the CHASE_DB1 dataset are 0.5058, 0.8947, 0.9382 and 0.8856, and the worst values are 0.5639, 0.9581, 0.9137 and 0.7110. The investigational results show that the suggested approach provides the excellent accuracy in comparison with other approaches.

As a cost effective measure to attain security and confidentiality of data, Virtual Private Network (VPN) is used to interconnect two networks. The research shows that the protocols and algorithms of VPNs adds the overhead and in turn affect the network performance. The two end point hardware appliances are configured with standard configuration to establish site to site VPN. There are different data formats transferred via these tunnels. A research was conducted in a simulation environment of open source technology to identify the various factors impacting the performance of data transfer via VPN tunnels. Empirical measurement shows that performance depends critically on nature of data and compressibility in different internet bandwidth conditions. This was also noticed that nested VPN architecture adds complexity in security at the cost of multifold transmission delays. VPN provide security at the cost of performance; hence application specific cost benefit analysis is essential to choose the optimal architecture.
