A Position Balanced Parallel Particle Swarm Optimization Method for Resource Allocation in Cloud

Objective: The main objective of this research is to allocate the resources with high profit and achieve high user satisfaction level in the cloud computing environment. Methods: An innovative technique called Position Balanced Parallel Particle Swarm Optimization (PB-PPSO) method is introduced for allocating resources. The main intent of PB-PPSO is to find the optimized resources for the set of tasks with less make span and minimum price. The set of rules are generated from the optimized resources for the training process. In the testing process, the resources are allocated to the new users by learning the rules from the training process. Results: PB-PPSO method shows high profit when compared to the existing methods such as Support Vector Machines (SVM) and Artificial Neural Network (ANN). In the PB-PPSO method, the optimized set of resources is determined for the set of tasks by using the particle swarm optimization algorithm. Then the rules are generated for the classification process. If the arrival rate of users is 500, the total profit is 720$ and the response time is 78ms. Based on the comparison and the results from the experiment shows the proposed approach works better than the other existing systems with high profit and less average response time. Conclusion: The findings demonstrate that the PB-PPSO is presented and this method has high efficiency in terms of total profit and average response time for allocating the resources for the users.

Guranteed Best Effort QoS Algorithm for Task Schedulingon Heterogeneous Grid Resources

Grid Computing enables the flexible sharing with resources among various dynamically created virtual organizations. Task Scheduling in Grid environment is a very important problem. To utilize the Grid resources efficiently, an efficient task scheduling algorithm is helping to schedule the tasks to the resources with reduced makespan. The problem of mapping metatask to the machines is shown to be NP-Complete. The NP-Complete problem can be solved using heuristic approaches. The proposed heuristic approach is based on QoS requirements. This paper proposes a Guaranteed Best Effort QoS Algorithm (GBEQoS) which achieves user satisfaction with minimum time and cost constraint in completing the task execution. The experimental results reveal that the proposed GBEQoS algorithm achieves reduced makespan with higher user satisfaction.

Continuous and transparent multimodal authentication: reviewing the state of the art

Individuals, businesses and governments undertake an ever-growing range of activities online and via various Internet-enabled digital devices. Unfortunately, these activities, services, information and devices are the targets of cybercrimes. Verifying the user legitimacy to use/access a digital device or service has become of the utmost importance. Authentication is the frontline countermeasure of ensuring only the authorized user is granted access; however, it has historically suffered from a range of issues related to the security and usability of the approaches. They are also still mostly functioning at the point of entry and those performing sort of re-authentication executing it in an intrusive manner. Thus, it is apparent that a more innovative, convenient and secure user authentication solution is vital. This paper reviews the authentication methods along with the current use of authentication technologies, aiming at developing a current state-of-the-art and identifying the open problems to be tackled and available solutions to be adopted. It also investigates whether these authentication technologies have the capability to fill the gap between high security and user satisfaction. This is followed by a literature review of the existing research on continuous and transparent multimodal authentication. It concludes that providing users with adequate protection and convenience requires innovative robust authentication mechanisms to be utilized in a universal level. Ultimately, a potential federated biometric authentication solution is presented; however it needs to be developed and extensively evaluated, thus operating in a transparent, continuous and user-friendly manner.

Various Dynamic Load Balancing Algorithms in Cloud Environment: A Survey

Cloud computing is emerging as a new standard model for enabling ubiquitous network access, computing resources, deploying, organizing, and accessing vast distributed computing applications over the network. In cloud computing, Load balancing is one of the main challenges which are required to distribute the workload equally across all the nodes. Load balancing uses services offered by many computer network service provider corporations. Load balancing can be different types like network load, storage capacity, memory capacity and CPU load. Load balancing helps to achieve a high user satisfaction and resource utilization ratio by confirming an efficient and fair allocation of every computing resource. Proper load balancing support in implementing failover, enabling scalability, overprovisioning, and decreases costs associated with document management systems and maximizes the availability of resources. This paper describes a survey of different dynamic load balancing algorithms in the cloud environment with their comparisons on the bases of different load balancing metrics.

콘텐트 중심 네트워크에서 정규표현식을 활용한 캐시친화적인 적응형 스트리밍 프레임워크

인터넷을 이용하는 사용자의 관점이 호스트 중심에서 콘텐트 중심으로 변화하면서 콘텐트 중심 네트워크 (Content Centric Network, 이하 CCN)라는 새로운 패러다임이 소개되었다. 한편, 최근 비디오 스트리밍에 대한 수요가 급증하고 있으며 더 높은 사용자의 만족도를 위한 적응형 스트리밍이 소개되면서 많은 연구가 진행 중에 있다. 따라서 CCN에서도 사용자의 수요에 따라 적응형 스트리밍을 고려할 필요성이 있다. 하지만 CCN에서 기존의 네트워크 구조에서와 동일한 방식으로 적응형 비디오 스트리밍 서비스를 할 경우 CCN 라우터 내 캐시를 (CS) 충분히 활용하지 못한다는 한계점이 있으며 또한 단말의 달라지는 요구 사항을 캐시 활용에 반영할 수 없는 문제점도 있다. 따라서 본 논문에서는 정규표현식을 활용한 콘텐트 네이밍 방식을 적용하여 기존 적응형 스트리밍 비트레이트 선택 알고리즘의 캐시활용도를 높이면서도 CCN의 기본 프로토콜에 적합한 프레임워크를 제시하고, 단말의 상태에 따라 동적인 표현식 기술 전략 및 선택 알고리즘을 통하여 비디오 스트리밍 품질을 개선하고자 한다. Content Centric Network (CCN) has been introduced as a new paradigm due to a shift of users's perspective of using Internet from host-centric to content-centric. On the other hand, a demand for video streaming has been increasing. Thus, Adaptive streaming has been introduced and researched for achieving higher user's satisfaction. If an architecture of Internet is replaced with CCN architecture, it is necessary to consider adaptive video streaming in CCN according to the demand of users. However, if the same rate decision algorithm used in Internet is deployed in CCN, there are a limitation of utilizing content store (CS) in CCN router and a problem of reflecting dynamic requirements. Therefore, this paper presents a framework adequate to CCN protocol and cache utilization, adapting content naming method of exploiting regular expression to the rate decision algorithm of the existing adaptive streaming. In addition, it also improves the quality of video streaming and verifies the performance through dynamic expression strategies and selection algorithm of the strategies.

Online emotional support delivered by trained volunteers: users’ satisfaction and their perception of the service compared to psychotherapy

Background: Technology could answer the substantial need in human resources available for supporting those who suffer from mental illness, by providing scalable methods to train and engage non-professionals to those who need their support. 7 Cups of Tea (7COT) platform was chosen for this study, because it provides a good case study for examining this kind of solution.Aim: The aim of this paper was to provide empirical findings regarding users’ satisfaction with online emotional support provided by trained volunteers and how it is perceived in comparison to psychotherapy.Methods: An online survey was conducted among a convenience sample of 7COT users.Results: The findings showed high user satisfaction with the support provided by 7COT listeners and, on average, users who indicated to receive psychotherapy in their past marked the listeners’ support to be as helpful as psychotherapy. Relating to psychotherapy and online emotional support advantages, different advantages were found. The findings suggest that receiving support from volunteers makes users feel that the support is more genuine.Conclusion: The paper provides preliminary evidence that people in emotional distress may find non-professionals support delivered through the use of technology to be helpful. Limitations and implications are discussed.

An End has a Start – Investigating the Usage of Electric Vehicles in Commercial Fleets

Abstract The road transport system is moving, slowly but surely, away from using fossil fuels. Plug-in electric vehicles (PEVs) are an energy-efficient alternative to conventional vehicles. Commercial vehicle fleets are an attractive entry for PEVa into the transport system. This paper presents findings from a three-year study of 550 PEVs and their users. A combination of technical and social science methods provides a basis for greater understanding of PEV operations in commercial vehicle fleets. This paper shows that battery electric vehicles (BEVs) have proven their functionality in several applications, but that winter conditions still imply an unjustified decrease in use. Usage varies according to application but results show that in general a substantial share of the battery capacity is redundant. Findings indicate that usage is not necessarily inhibited by the technical specifications of the battery but by the operational conditions in which commercial duties are performed. The only reliable alternative is to return with a large battery surplus. The vehicles studied have demonstrated their functionality and the users are positive. Plug-in hybrid electric vehicles (PHEV) imply no restrictions in mobility, which results in high user satisfaction. Commercial vehicle fleets are suitable for PEV operations and with growing acceptance users have requested more PEVs hence a significant possibility exists to substitute a large share of the fossil-fuelled vehicles operating in commercial vehicle fleets.

Energy Efficiency and User Comfort in the Workplace: Norwegian Cellular vs. British Open Plan Workplaces

Two office layouts with high and low levels of thermal control were compared, respectively Norwegian cellular and British open plan offices. The Norwegian practice provided every user with control over a window, blinds, door, and the ability to adjust heating and cooling. Occupants were expected to control their thermal environment to find their own comfort, while air conditioning was operatingin the background to ensure the indoor air quality. In contrast, in the British office, limited thermal control was provided through openable windows and blinds only for occupants seated around the perimeter of the building. Centrally operated displacement ventilation was the main thermal control system. Users’ perception of thermal environment was recorded through survey questionnaires, empirical building performance through environmental measurements and thermal control through semi-structured interviews. The Norwegian office had35% higher user satisfaction and 20% higher user comfort compared to the British open plan office. However, the energy consumption in the British practice was within the benchmark and much lower than the Norwegian office. Overall, a balance between thermal comfort and energy efficiency is required, as either extreme poses difficulties for the other.

A Pilot Study Evaluating "Dojo," a Videogame Intervention for Youths with Externalizing and Anxiety Problems.

Externalizing problems, which are the main reason for youth referrals to mental health agencies, are highly persistent and predict a range of negative outcomes. Youths with externalizing problems are also frequently comorbid with anxiety. Among the most widely recognized evidence-based treatments is cognitive behavioral therapy (CBT). Although CBT principles seem to be sound, effect sizes remain moderate, suggesting improvements could be made to this conventional treatment approach. The main premise of the current pilot study is to investigate the feasibility of implementing a videogame intervention ("Dojo" [Gamedesk, Los Angeles, CA]) that incorporates CBT principles and aims to address the limitations of conventional CBT delivery models, with the ultimate goal of improving outcomes for this difficult-to-treat population. "Dojo" is an emotion management game that helps youths to recognize and control their physiological and emotional arousal. We explored the implementation and user experience of "Dojo" in a sample of eight adolescents in residential treatment for both externalizing and anxiety problems. Participants attended all sessions without complaints. They evaluated "Dojo" very positively and exhibited high compliance during the training sessions. We encountered some problems with session scheduling and obtaining mentor reports. Quantitative data show the predicted decrease in three out of four measurements. The smooth implementation, high user satisfaction, high self-reported compliance during training sessions, and initial outcome results all indicate the high potential "Dojo" holds as an innovative intervention. If additional rigorously designed randomized controlled trials prove to be successful, "Dojo" can be a cost-effective way to engage high-risk youths in effective intervention.

An Enterprise Systems Model to Deliver Innovation in the Healthcare Industry Based on Cognitive and Social-Tech Engineering

An optimal enterprise system that fosters innovation is based on people, process and technology. However, current enterprise systems lack a significant involvement of the human aspects. An innovation model can incorporate those three components to provide greater value to stakeholders, drive organizational growth, gain a competitive advantage and achieve greater end-user satisfaction. We investigated how an enterprise systems model for open innovation could be created based on existing innovation socio-technical frameworks and how that model may benefit the UK National Health Service (NHS). We carried out a literature review of enterprise systems models, cognitive and social-tech engineering and innovation management. Two researchers undertook a thematic analysis of 46 academic papers. Themes included business sectors, types of innovation strategy and the use of cognitive and social-tech engineering elements. Results show that little application of innovation models within the healthcare sector has been undertaken to foster innovation. We suggest that existing innovation frameworks such as the Innovation Pentathlon Framework, the NASA's partnering incentive and the Tesco club card scheme may be the basis for the creation of a healthcare innovation model that incorporates substantive human aspects, including human cognition and human reward. Since the cost of missing medical appointments in the NHS is around $1390 million dollars per year, our innovation model may be implemented to improve patient attendance to family doctors and hospital appointments. The model strategy comprises rewarding people with shopping vouchers (Tesco club card points or nectar points) each time they confirm or cancel a medical appointment online or by SMS text message. With this model, the NHS would improve the management of their resources, may improve the quality of service and may have higher user satisfaction. Nevertheless, future challenges may include the adaptation of current NHS business processes and the management of the collaboration with private organizations.

USABILITY EVALUATION OF TEMPERATURE REGULATION SMART CLOTHING INTERFACE

This study developed a user focused interface to improve a temperature regulation smart wear system controlled by a textile switch embedded on the outer surface. Designers need to investigate problems between design and consumers to enhance usability. Companies usually launch a final product where problems are resolved by repeated usability evaluation from the initial stage of product development. A textile switch was made all fabric for natural wear ability and designed for easy control and hands-free operation. Usability evaluation for textile switch design was conducted after reading manual without functioning. The survey selected five possibilities (metaphor, consistency, efficiency, flexibility, and aesthetic) from 10 heuristic evaluation assessment criteria of Nielsen(Feedback, metaphor, control, consistency, error prevention, efficiency, flexibility, aesthetic, recover form error, and help) to evaluate with a 5-point Likert-type rating scale restricted by 17 questions that collected specific opinions about user satisfaction. We randomly selected 20 general users to conduct the survey. A textile switch was made all fabric for natural wear ability and designed for easy control and hands-free operation.

We modify the final prototype based on usability problems selected through subjective evaluation.

Vouchers for family planning and sexual and reproductive health services: A review of voucher programs involving Marie Stopes International among 11 Asian and African countries

ObjectivesTo evaluate provision of vouchers for family planning and sexual and reproductive health (SRH) services. MethodsA review was conducted to assess the effects of 24 voucher programs in Marie Stopes International programs across 11 countries in Asia and Africa between 2005 and the present. The outcome measures were uptake of services; service use among specific subgroups; user satisfaction with service quality; and efficiency of service delivery. ResultsTwelve of the 24 programs covered family planning only, whereas the other 12 programs covered family planning and/or SRH. Service uptake increased following implementation, although voucher redemption rates varied by program (44.1%–92.4%). Most programs were successful in reaching subgroups, such as the poor and young (under 25years), although this outcome depended on the targeting approach. Most programs recorded high user satisfaction; however, the evidence regarding efficiency was mixed. ConclusionsVouchers increased uptake of services and, in some cases, improved service quality and reach to specific groups. Nevertheless, robust evaluation designs are required to measure efficiency.

Web-Based Education Prior to Knee Arthroscopy Enhances Informed Consent and Patient Knowledge Recall: A Prospective, Randomized Controlled Study.

Preoperative patient education is an important part of the informed consent process, and a perceived lack of information can lower patient satisfaction. We sought to evaluate the effect of a web-based multimedia patient education tool on the perioperative experience of patients undergoing first-time knee arthroscopy for a meniscal tear. Adult patients undergoing knee arthroscopy for the first time for a primary diagnosis of a meniscal tear were consecutively enrolled into the study from January 2014 through June 2014. Patients were equally randomized to a control group, who received standard preoperative counseling, or the intervention group, who completed a twenty-minute web-based multimedia tutorial in addition to standard counseling. The web-based tutorial covered relevant anatomy, pathology, and general perioperative instructions, and it was completed prior to the preoperative visit. Patients completed surveys that evaluated their preparedness for surgery and knowledge recall at the preoperative visit, on the day of surgery, and after the first postoperative visit. Sixty-four patients were enrolled, and fifty-five patients (86%; twenty-nine in the control group and twenty-six in the intervention group) with complete data sets were included in the analysis. Preoperatively, the intervention group felt significantly more informed about the surgery and more clearly understood the risks and benefits of, and alternatives to, the surgery (all p < 0.001). Postoperatively, the intervention group reported being significantly more satisfied with the perioperative education that they had received and felt more informed about their surgery and rehabilitation (p ≤ 0.05). Patients in the intervention group were significantly more likely to correctly answer questions regarding their surgical details at the first postoperative visit (p ≤ 0.03). Patients who completed the web-based tutorial had improved preoperative knowledge and preparedness as well as enhanced postoperative knowledge recall regarding their surgical procedure. The tutorial received high user satisfaction scores with low user burden scores and was an effective tool for enhancing the patients' perioperative experience.

Virtual Reference Services in Modern Libraries

Reference Service is an important personalized in the library and information centers. Traditionally, it is a one-to-one provided by the reference librarian to users. But the present epoch is being transformed by the technology. Thus, with the progression of shifting technology the approaches of providing reference in the libraries are gradually changing. Nowadays it is offered to the user in a fresh and more developed form called as reference service, also known as reference service Mahrana & Panda, n. d.. Virtual reference is reference commenced by electronic means where patrons employ technology a computer or any other form to communicate with the professionals without being physically present. The modes of communication often used in virtual reference include e-mail, instant messaging, chat, Voice-over-IP, videoconferencing, co-browsing etc. RUSA, 2010. Virtual Reference Services VRS have high user satisfaction Mu, Dimitroff, Jordan, & Burclaff, 2011. As libraries make more digital resources available over the web, virtual reference traffic is consequently expected to increase. According to Gray 2000a more internet use is equal to more Virtual reference traffic. The present article aims to discuss the concept of Virtual Reference Services in contemporary libraries. It also assesses nascent modes of providing quality Virtual Reference Services. Further the chapter also discusses reputed Virtual Reference systems of select online Libraries.

A Model of Spinal on Call: Orthopedic Spinal Rapid Access Service: Results of 6-Month Prospective Audit

Introduction Provision of structured on-call rota for spinal conditions can be challenging in the most orthopedic department because of the limited number of spinal surgeons. Spinal emergencies are therefore managed often by general orthopedic surgeons with potential of suboptimal outcome. Spinal conditions are managed in our institute with a team of spinal surgeons and nonmedically qualified spinal clinicians. Orthopaedic Spinal Rapid Access Service (OSRAS) was developed in our institute to provide a structured pathway for management of urgent spinal pathologies during working hours of Monday to Friday. It was delivered through a published rota by a multidisciplinary team of nonmedically qualified spinal clinicians carrying a bleep and a spinal surgeon. Aim This study aims to evaluate the efficacy of OSRAS through a prospective audit. Materials and Method New service development protocol was followed and board approval for this project was obtained. A spinal on-call rota was designed and was published to limited number of clients. The data obtained for all patients who were referred to the OSRAS services were collected prospectively in a predesigned performa that was approved by the audit department in our institute and analyzed. Results Between Nov 2013, 1, and April 30, 2014, 177 patients (48 males and 119 females) with an average age of 50 (range, 17–95 years) years were referred to OSRAS. Wednesday was the busiest day with 26% referral in AM and 74% in PM. Main source of referrals were as follows: regional MSK services (50), triage (34), ED (27), and GPs (20). The reasons were as follows: suspected CESI ( n = 100), acute LBP ( n = 30), pathological fractures ( n = 23), progressive neurology ( n = 16), discitis ( n = 5), and spinal stenosis ( n = 2). Depending on clinical needs, 29 patients were seen on the same day, 33 next day, 53 within 2 to 5 days, and 31 patients more than 5 days. Overall, 80 patients were discharged, 36 listed for surgery, 27 required further follow-up, and 31 patients were given telephone advise only. High user satisfaction rating was obtained. Conclusion We propose an OSRAS model as a safe and cost-effective alternate to often unsatisfactory current emergency department model that can provide a structured pathway for timely expert management of serious spinal pathologies therefore prevent potential consequences while avoid unnecessary admissions.

Changing the (Video) Game: Innovation, User Satisfaction and Copyrights in Network Market Competition

This paper explores the emerging trend of user-generated content and innovation in the development of new products and ideas, breaking the traditional producer-consumer paradigm that once dominated the marketplace. In particular, the paper evaluates and compares the relationship between innovation and user satisfaction within the video game industry. To do so, the paper assesses data collected from the online communities of two very different games, Minecraft and Call of Duty in order to determine if there is a link between user-innovation and user-satisfaction in a product. The authors predict that more innovation in a game leads to more user satisfaction. The results of the research do not support this prediction. As observed in the online communities of the two games, there is no clear connection between high levels of innovation with higher user satisfaction. In fact, there is no direct connection between innovation and user satisfaction. However, Minecraft was found to be the more innovative game of the two and did have an overall higher level of user satisfaction than compared to Call of Duty. The data also suggests that Minecraft players experience a greater fluctuation in their enjoyment of the game compared to the players of the game with less innovation, Call of Duty. Finally, “radical innovation,” was only found in Minecraft and not in the game with less player-control. This paper then goes on to discuss the role of innovation and user-generated digital content within the realm of intellectual property law and the resulting copyright implications for video game producers and players alike.

Cognitive Network Management Framework and Approach for Video Streaming Optimization in Heterogeneous Networks

The future Internet will be highly heterogeneous in supporting a multitude of access technologies and networks with overlapping coverages. Optimization of network operations like management of resources, mobility or Quality of Service in order to ensure smooth network operation and high user satisfaction will be very challenging in the future networks. Cognitive network management can provide a solution of managing such complex systems. This paper studies cognitive network management in the context of optimizing video streaming performance in heterogeneous multi-access networks. The paper proposes a network management framework that relies on cognitive decision techniques in the joint optimization of network and video service performance. The proposed solution is also implemented and validated in part in a testbed environment. The results attest the feasibility of the solution as well as the benefits of cognitive decision techniques over non-learning or non-adaptive approaches.

Knowledge and Training of Intrauterine Devices Among Primary Care Residents: Implications for Graduate Medical Education.

Nearly half of pregnancies in the United States are unintended, a rate that has increased recently, contrasted with a worldwide decline.1,2 This lack of progress may be due to low adoption of long-acting reversible contraceptives (LARCs). The United States has the lowest rate of intrauterine device (IUD) use of any industrialized country.3,4 Because IUDs have high user satisfaction and effectiveness, increased adoption could lead to reductions in unplanned pregnancies (and fewer adverse outcomes) and prevent abortions.4,5 Both in public and private sectors, primary care providers have an important role in preventing unintended pregnancies. Although many women receive contraceptive counseling and services from obstetrics and gynecology (ob-gyn) specialists, a significant proportion see family practitioners, internists, and pediatricians (caring for adolescents) for one or both.6 The National Ambulatory Medical Care Survey is designed to meet the need for objective, reliable information about the provision and use of ambulatory medical care services in the United States. According to the latest data available from this survey, 11.5 million visits occurred in 2010 for contraception and family planning counseling.7 It is important, therefore, that all provider types be well informed regarding IUDs. A significant proportion of physicians trained in primary care specialties add further training in subspecialties: subspecialist physicians take care of women with complex medical problems that pose a significant risk for pregnancy. Therefore, contraception knowledge is important to medical and pediatrics subspecialists as well. Although the Accreditation Council for Graduate Medical Education requires training in family planning and contraception as part of the core curriculum for internal medicine, pediatrics, family medicine, and ob-gyn residents, structured teaching in the area of contraception is not necessarily a systematic part of this curriculum (B O X).8

What is Intuitive Interaction? Balancing Users' Performance and Satisfaction with Natural User Interfaces

Designers of natural user interfaces are faced with several challenges when creating interaction models for controlling applications, including the wide range of possible input actions and the lack of affordances, which they can use to design controls. In order to contribute to the development of design guidelines in this design space, we conducted an exploratory, mixed methods study. We investigated three top-down approaches to designing intuitive interaction mappings for a whole body system implemented with camera vision. These were metaphoric, isomorphic and ‘everyday’or conventional. In order to identify some of the benefits and limitations of each approach, we compared the designs based on measures of usability, intuitiveness and engagement with the material represented in the system. From our study, we found that while the metaphoric design enhanced users’ performance at completing tasks, the lack of discoverability of the interaction model left them feeling incompetent and dissatisfied. We found that the isomorphic design enabled users to focus on tasks rather than learning how to use the system. Conversely, designs based on previous conventions had to be learned, had a time cost for the learning and negatively impacted users’ engagement with content. For tasks and controls that can be designed based on an image schematic input action, users performed most accurately with the metaphoric design. There are benefits and limitations to each approach to designing to support intuitive interaction. We conclude with preliminary design considerations, suggest ways to balance performance with high user satisfaction depending on contextual design goals and question a single definition of intuitive intuition within whole body interface design.
