On the power laws of language: word frequency distributions
No full textAbout eight decades ago, Zipf postulated that the word frequency distribution of languages is a power law, i.e., it is a straight line on a log-log plot. Over the years, this phenomenon has been documented and studied extensively. For many corpora, however, the empirical distribution barely resembles a power law: when plotted on a loglog scale, the distribution is concave and appears to be composed of two differently sloped straight lines joined by a smooth curve. A simple generative model is proposed to capture this phenomenon. Theword frequency distributions produced by this model are shown to match the observations both analytically and empirically. © 2017 Copyright held by the owner/author(s)
Social Media in Tourism A Double Edged Sword
No full textExtensive spread of the Internet and speedy technological advancement have revolutionized all industries in the World specifically tourism. The presence of the information and communication technology have fundamentally change the way how tourists collect detailed information, how do they can carefully map decision substitutes, how they book their travel and how they share their unique travel experience with others. A vital step forward in the progress of the internet has been made by a noteworthy growth in the popularity of social media platforms. Social media plays a very important role in tourism which is an information based industry. Consumers need information that can assist them in the process of travel planning and making decisions related to selection of tourism destination and other travel related products. Social media has also extended the reach of industry as now they can easily target consumers sitting far away without even meeting them. Destination marketer use social media before the travel so as to engage and inform the tourists, during the travel so as to facilitate at destination and after the travel to remember and share experiences. But social media in tourism marketing can be both an aid and a threat as social media influences the tourism industry both in positive and negative ways, as the decisions of prospective travellers have been strongly affected by comments and personal experiences of other users on social media. The main objective of the paper is to understand the relationship between social media and destination marketing and to examine the positive and negative impact of social media marketing in tourism industry.

Visual impairment among weaving communities in Prakasam district in South India.
No full textPURPOSE: To assess the prevalence and causes of visual impairment in weaving communities in Prakasam district in South India state of Andhra Pradesh. METHODS: Using Rapid Assessment of Visual Impairment (RAVI) methodology, a population based cross-sectional study was conducted. A two-stage sampling strategy was used to select 3000 participants aged ≥40 years. Visual Acuity (VA) was assessed using a tumbling E chart and ocular examinations were performed by trained Para medical ophthalmic personnel. A questionnaire was used to collect personal and demographic information. Blindness and moderate Visual Impairment (VI) was defined as presenting VA <6/60 and <6/18 to 6/60 respectively. VI included blindness and moderate VI. RESULTS: 2848 of 3000 enumerated subjects (94.0%) participated. 39% were in 40-49 years age group and 11.8% were aged ≥70 years, 55% were women and nearly half of them had no formal education. 400 (14%; 95% CI: 12.8-15.3) subjects had VI, including blindness in 131 (4.6%; 95% CI: 3.8-5.4) and moderate VI in 269 (9.4%; 95% CI: 8.3-10.5) individuals. On applying multiple logistic regression, VI was significantly associated with older age and no formal education. Though the odds of having VI were higher in females, it was of borderline statistical significance (p = 0.06). Refractive error was the leading cause of all VI followed by cataract (56%). However, refractive errors were the leading cause of moderate VI (73.2%) and cataract was the leading cause of blindness (62.6%). 'Cannot afford the cost of services' was the leading barrier for utilization of eye care services (47%). CONCLUSIONS: There is a significant burden of VI in weaving communities in Andhra Pradesh, India most of which is avoidable. With this information as baseline, services need to be streamlined to address this burden

Experience report: Scala collections
No full textWe report on our experiences in redesigning Scala's collection libraries, focussing on the role that type systems play in keeping software architectures coherent over time. Type systems can make software architecture more explicit but, if they are too weak, can also cause code duplication. We show that code duplication can be
avoided using two of Scala's type constructions: higher-kinded types and implicit parameters and conversions.sponsorship: The second author (Adriaan Moors) is supported by a grant from the Flemish IWT.status: Publishe
Co-creating Responsible Energy Systems
No full textEnergy system projects in countries like India are often failing. Not only because of technical or economical barriers, but mainly institutional and social issues are at the base of these failures. A co-creation, or participatory, process to align all demands and requirements of the different stakeholders is required. This paper takes evidence from literature on co-creation and energy systems and from case study research in India to help define an approach towards such a co-creation process as a use case for the application of the Responsible Innovation Systems framework. A discussion on co-creation as a solution generates a number of recommendations, after which a set of characteristics is concluded that the co-creation process of energy systems should have towards a responsible approach, so that more robust and sustainable innovations might emerge.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Energy and IndustryDelft Centre for Entrepreneurshi
The use of dynamic networks in scheduling flexible manufacturing systems
No full textFlexible Manufacturing Systems have developed recently to allow companies to compete in a global market. One problem arising from such systems is the optimal scheduling of the jobs through the system. There is much discussion as to what this problem should be, but it is agreed that it is a hard problem.This thesis deals with the scheduling problem as defined by Stecke as problems concerning the running of an FMS once it has been set up during a planning phase. Numerous techniques have been proposed to solve this problem.If the problem is static, various queueing models may be used. However, in a dynamic environment these models fail. Mathematical programming models allow for the dynamic environment, but rapidly increase in calculation requirements due to the need for integer answers. Simulation, hierarchical, and expert systems try to address this problem, but don't allow for optimal solutions.The use of a dynamic network model had been considered in the past, but rejected for various reasons. The thrust of this thesis is that these networks can be used and are a computationally feasible technique for finding optimal solutions to the FMS scheduling problem. In order to develop this concept, the basic dynamic network models originally proposed by Maxwell & Wilson needed to be expanded and modified.By incorporating the concepts of limited entry queues and micromodels of resources, a dynamic network model of an FMS can be developed and solved by efficient network flow techniques.Made available in DSpace on 2011-05-07T13:24:13Z (GMT).

Enhancement of observability using Kubernetes operator
No full textObservability is the ability for us to monitor the state of the system, which involves monitoring standard metrics like central processing unit (CPU) utilization, memory usage, and network bandwidth. The more we can understand the state of the system, the better we can improve the performance by recognizing unwanted behavior, improving the stability and reliability of the system. To achieve this, it is essential to build an automated monitoring system that is easy to use and efficient in its working. To do so, we have built a Kubernetes operator that automates the deployment and monitoring of applications and notifies unwanted behavior in real time. It also enables the visualization of the metrics generated by the application and allows standardizing these visualization dashboards for each type of application. Thus, it improves the system's productivity and vastly saves time and resources in deploying monitored applications, upgrading Kubernetes resources for each application deployed, and migration of applications
