Genetic Algorithm- A Literature Review

Abstract: Genetic Algorithm (GA) may be attributed as method for optimizing the search tool for difficult problems based on genetics selection principle. In additions to Optimization it also serves the purpose of machine learning and for Research and development. It is analogous to biology for chromosome generation with variables such as selection, crossover and mutation together constituting genetic operations which would be applicable on a random population initially. GA aims to yield solutions for the consecutive generations. The extent of success in individual production is directly in proportion to fitness of solution which is represented by it, thereby ensuring that quality in successive generations will be better. The process is concluded once an GA is most suitable for the issues that need optimization associated with some computable system.. John Holland may be regarded as funding father of original genetic algorithm and is attributed to year 1970’s as funding date. Additionally a random search method represented by Charles Darwin for a defined search space in order to effetely solve a problem. In this paper, what is genetic algorithm and its basic workflow is discussed how a genetic algorithm work and what are the process is included in this is also discussed. Further, the features and application of genetic algorithm are mentioned in the paper.

Do You See What I See? The Effect of Gaze Tracking on Task Space Remote Collaboration

Abstract: We present results from research exploring the effect of sharing virtual gaze and pointing cues in a wearable interface for remote collaboration. A local worker wears a Head-mounted Camera, Eye-tracking camera and a Head-Mounted Display and shares video and virtual gaze information with a remote helper. The remote helper can provide feedback using a virtual pointer on the live video view. The prototype system was evaluated with a formal user study. Comparing four conditions, (1) NONE (no cue), (2) POINTER, (3) EYE-TRACKER and (4) BOTH (both pointer and eye-tracker cues), we observed that the task completion performance was best in the BOTH condition with a significant difference of POINTER and EYETRACKER individually. The use of eye-tracking and a pointer also significantly improved the co-presence felt between the users. We discuss the implications of this research and the limitations of the developed system that could be improved in further work.

Future Internet: The Internet of Things-A Literature Review

Abstract: Internet today is the backbone of virtual communication worldwide. It is expanding its horizon with a fast pace. Internet is rightly defined as “network of networks”. It is, in most simple terms, a means of establishing a connection between your computer and any other computer globally through servers and some dedicated routers. The major form of communication of current Internet is among humans (i.e. human-to-human). The next upcoming form of communication that uses Internet as the underlying technology is The Internet of Things (IoT). IoT extends the capabilities of Internet to enable machine-to-machine communication (M2M).Therefore, IoT can be said to provide communication among everyone and everything. IoT enables us to embed some sort of intelligence in the objects that are or can be connected to the Internet in order to exchange information, hence communicate, invoke certain actions based on inputs, take decisions and provide useful services. In this paper, the basic underlying workflow of IoT is discussed and the architecture of IoT is explained. The paper also highlights the most useful technologies of these days, which employ IoT for their functioning. Further, the applications and features of IoT are mentioned in the paper. Lastly, the issues and challenges in implementing the IoT are briefly discussed. The IoT today is gaining a lot of recognition due to its potential that is yet to be extracted by the industry, academia and government as well. These sectors can bring huge economic and professional benefits by employing IoT in the right manner.

Measuring Human Trust in a Virtual Assistant using Physiological Sensing in Virtual Reality

Abstract: With the advancement of Artificial Intelligence technology to make smart devices, understanding how humans develop trust in virtual agents is emerging as a critical research field. Through our research, we report on a novel methodology to investigate user’s trust in auditory assistance in a Virtual Reality (VR) based search task, under both high and low cognitive load and under varying levels of agent accuracy. We collected physiological sensor data such as electroencephalography (EEG), galvanic skin response (GSR), and heart-rate variability (HRV), subjective data through questionnaire such as System Trust Scale (STS), Subjective Mental Effort Questionnaire (SMEQ) and NASA-TLX. We also collected a behavioral measure of trust (congruency of users’ head motion in response to valid/ invalid verbal advice from the agent). Our results indicate that our custom VR environment enables researchers to measure and understand human trust in virtual agents using the matrices, and both cognitive load and agent accuracy play an important role in trust formation. We discuss the implications of the research and directions for future work.

Provider-Verified HPV Vaccine Coverage among a National Sample of Hispanic Adolescent Females

Abstract: Background: Hispanic females have the highest cervical cancer incidence rate of any racial or ethnic group in the United States, yet relatively little research has examined human papillomavirus (HPV) vaccination among this fast-growing population. We examined HPV vaccination among a national sample of Hispanic adolescent females. Methods: We analyzed provider-verified vaccination data from the 2010–2011 National Immunization Survey-Teen for Hispanic females ages 13 to 17 years ( n = 2,786). We used weighted logistic regression to identify correlates of HPV vaccine initiation (receipt of one or more doses), completion (receipt of three doses), and follow-through (receipt of three doses among those who initiated the series). Results: HPV vaccine initiation was 60.9%, completion was 36.0%, and follow-through was 59.1%. Initiation and completion were more common among older daughters and those whose parents had received a provider recommendation to vaccinate (all P 0.05), although intent to vaccinate was higher among Spanish-speaking parents ( P < 0.01). Spanish-speaking parents were more likely to indicate lack of provider recommendation (20.2% vs. 5.3%) and cost (10.9% vs. 1.8%) as main reasons for not intending to vaccinate (both P < 0.05). Conclusions: Many Hispanic females have not received HPV vaccine. Several factors, including provider recommendation and health insurance, are key correlates of vaccination. Impact: HPV vaccination programs targeting Hispanics are needed and should consider how potential barriers to vaccination may differ by preferred language.

Model Driven Engineering

Abstract: The Object Management Group's (OMG) Model Driven Architecture (MDA) strategy envisages a world where models play a more direct role in software production, being amenable to manipulation and transformation by machine. Model Driven Engineering (MDE) is wider in scope than MDA. MDE combines process and analysis with architecture. This article sets out a framework for model driven engineering, which can be used as a point of reference for activity in this area. It proposes an organisation of the modelling 'space' and how to locate models in that space. It discusses different kinds of mappings between models. It explains why process and architecture are tightly connected. It discusses the importance and nature of tools. It identifies the need for defining families of languages and transformations, and for developing techniques for generating/configuring tools from such definitions. It concludes with a call to align metamodelling with formal language engineering techniques.

Revisiting Trends in Augmented Reality Research: A Review of the 2nd Decade of ISMAR (2008–2017)

Abstract: In 2008, Zhou et al. presented a survey paper summarizing the previous ten years of ISMAR publications, which provided invaluable insights into the research challenges and trends associated with that time period. Ten years later, we review the research that has been presented at ISMAR conferences since the survey of Zhou et al., at a time when both academia and the AR industry are enjoying dramatic technological changes. Here we consider the research results and trends of the last decade of ISMAR by carefully reviewing the ISMAR publications from the period of 2008–2017, in the context of the first ten years. The numbers of papers for different research topics and their impacts by citations were analyzed while reviewing them—which reveals that there is a sharp increase in AR evaluation and rendering research. Based on this review we offer some observations related to potential future research areas or trends, which could be helpful to AR researchers and industry members looking ahead.

Menstrual hygiene management among adolescent girls in India: a systematic review and meta-analysis

Abstract: Objectives To assess the status of menstrual hygiene management (MHM) among adolescent girls in India to determine unmet needs. Design Systematic review and meta-analysis. We searched PubMed, The Global Health Database, Google Scholar and references for studies published from 2000 to September 2015 on girls’ MHM. Setting India. Participants Adolescent girls. Outcome measures Information on menarche awareness, type of absorbent used, disposal, hygiene, restrictions and school absenteeism was extracted from eligible materials; a quality score was applied. Meta-analysis was used to estimate pooled prevalence (PP), and meta-regression to examine the effect of setting, region and time. Results Data from 138 studies involving 193 subpopulations and 97 070 girls were extracted. In 88 studies, half of the girls reported being informed prior to menarche (PP 48%, 95% CI 43% to 53%, I2 98.6%). Commercial pad use was more common among urban (PP 67%, 57% to 76%, I2 99.3%, n=38) than rural girls (PP 32%, 25% to 38%, I2 98.6%, n=56, p Conclusions Strengthening of MHM programmes in India is needed. Education on awareness, access to hygienic absorbents and disposal of MHM items need to be addressed. Trial registration number CRD42015019197.
