Abstract: Computing hungry multimedia web applications need to efficiently utilize all the resources of a device. HTML5 web workers is a non-sharing concurrency platform that enables multimedia web application to utilize the available multicore hardware. HTML5 web workers are implemented by major browser vendors to facilitate concurrent execution in web clients and enhance the quality of ambitious web applications. The concurrent execution in web workers allows parallel processing using available cores at the expense of communication overhead and extra computation. The benefits of concurrent execution can be maximized by balancing load across workers/CPU cores. This work presents load-balancing algorithms between web workers using parameters such as scheduler throughput, computation priority and game entities locality.An award-winning web-based multimedia game (raptjs.com) is used to evaluate the performance of load balancing algorithms. The preliminary results indicated that the performance of game improved with the proposed load-balancing across web workers. The load balancing algorithms were developed on top of DOHA [1], an open source JavaScript execution layer for multimedia applications. The load between web workers is transferred between web workers via serialized objects. Effects of load transfer between on the overall application performance was measured by analysing jitter and number of frames per second. Load balancing algorithms and load transfer mechanism can be used by developers to improve the application design, and giving end users better perceived quality of experience for demanding multimedia web based applications.

Keywords: Web workers, concurrent execution, load balancing.

Abstract: Almost every website, mobile application or cloud service requires users to agree to a privacy policy, or similar terms of service, detailing how the developer or service provider will handle user data, and the purposes for which it will be used. Many past works have criticised these documents on account of their length, excessively complex wording, or the simple fact that users typically do not read or understand them, and that potentially invasive or wide-reaching terms are included in these policies. In this paper, an automated approach and tool to gather and analyse these policies is presented, and some important considerations for these documents are highlighted, specifically those surrounding past legal rulings over the enforceability of some specific and widely-used contract terms – the ability for terms to be changed without directly notifying users (and presumed continued use indicates acceptance), and the protections in place in the event of a sale or acquisition of a company. The concerns these pose to user privacy and choice are highlighted, as well as the extent to which these terms are found in policies and documents from many popular websites. This tool was used to highlight how commonly these terms are found, and the extent of this potential problem, and explore potential solutions to the challenge of regulating user privacy via such contracts in an era where mobile devices contain significant quantities of highly sensitive personal data, which is highly desirable to service operators, as a core valuation asset of their company.

Abstract: Pharma industry is undergoing a major transformation called ‘The new pharma reality’ caused by the changes in global pharmaceutical business ecosystem and strive for the improved regulatory compliance and competitiveness. The current manufacturing and enterprise IT systems have not been satisfactorily able to deliver on the new requirements and this is leading pharma companies investigating the benefits of the current trends of digitalization, IoT and enhanced networking capabilities. This paper introduces the concept of Pharma Industrial Internet, a reference model for applying the 5G PPP Infrastructure, Industrial Internet Consortium Reference Architecture and key pharma industry manufacturing standards for specifying, modeling and building pharma industry specific industrial internet solutions. By applying the reference model, pharmaceutical manufacturers will be able to improve their competitiveness while meeting the global regulatory and manufacturing quality requirements. The paper provides a holistic view on the digitalization transformation taking place in the pharmaceutical industry, the technical enablers driving the transformation and the new service infrastructures and value-add enterprise services helping the pharma companies to compete in the new pharma reality.

Abstract: Universal service provision is a key to bridge the digital divide. This paper provides an empirical examination of the Vietnamese universal policy introduced in 2015 for implementation up to 2020. Using the framework of King et al. (1994) the paper analyses the universal services policy in Vietnam as well as the policies of broadband development in South Korea and Japan in order to clarify the types of universal service initiatives made in these countries. Furthermore, the paper compares the universal service policy in Vietnam with the broadband development policy in South Korea and in Japan in order to evaluate whether the Vietnamese universal policy is efficient. The paper concludes with a discussion of how an effective universal policy can be designed.

Keywords: Universal services, broadband, policy, supply, demand.

Abstract: The deployment of previous wireless standards has provided more benefits for urban dwellers than rural dwellers. 5G deployment may not be different. This paper identifies that Community Based Networks as carriers that deserve recognition as potential 5G providers may change this. The argument is hinged on a research aimed at understanding how and why Community Based Networks deploy telecom and Broadband infrastructure. The study was a qualitative study carried out inductively using Grounded Theory. Six cases were investigated.Two Community Based Network Mobilization models were identified. The findings indicate that 5G connectivity can be extended to rural areas by these networks, via heterogenous networks. Hence the delivery of 5G data rates delivery via Wireless WAN in rural areas can be achieved by utilizing the causal factors of the identified models for Community Based Networks.

Keywords: 5G, Community Based Networks, telecom infrastructure, telecom services, CBNM models.

Abstract: Methods for interaction design have emerged and established themselves first in a Scandinavian context, later in US context and in the rest of the developed world. While good usability and good user experiences are important to all users of ICT, the question is whether the methods and techniques that were mainly developed in Scandinavia, Europe and US are suitable for ICT development in West Africa? Can ideals for user-involvement be directly transferred? This paper aims to initiate a discussion of the communication of interaction design knowledge in West Africa by discussing whether insights from Scandinavian Participatory design can be used to localize the learning process and make interaction design methods sensitive to the West African context. The paper is based on the author’s reflection on his experiences teaching interaction design inWest Africa.

Abstract: Providing last-mile Internet access to rural areas in Africa is a very challenging task, i.e. many more or less successful attempts have been made over the years. One solution that seems to offer a sustainable business case is based onWiFi base stations with access points placed in the centers of the villages. Nevertheless, this solution has a limited range, especially inside the homes where the wall attenuation dominates. This paper provides a solution in the form of deploying a cheap, simple, and powerless passive repeater on the shielding walls. By simulating theWiFi radio-link between a base station and a user positioned inside a home, it has been found that the passive repeater lowers the wall attenuation considerably and thereby extends the usable range.

Abstract: Bottom - up Broadband infrastructure development facilitated by the civil societies and social enterprises are on the increase. However, the problem plaguing the development of these bottom-up approaches in developing countries is the financial capacity to expand their small networks into larger networks – leading to the demise of some of these initiatives. This paper proposes co-financing of these networks as a means of sustaining the bottomup Broadband network. The argument of this paper is anchored on two of developing country cases. One in India and the other in Ghana. One survived with financial injection and the other did not due to low revenue. This paper, based on these cases, proposes the utilization and the reintroduction of Universal Service funds in developing countries to aid these small networks. This is a qualitative study, the Grounded Theory approach was used adopted gather data for these cases.

Abstract: The aim of this paper is to analyse whether the developmental policy model applied for fibre roll-out in Sweden can be used as inspiration for the Danish telecom policy. This is done through a comparison of the two very different policy approaches applied in Denmark and Sweden. A case study on public intervention in the rural Swedish municipality of Almhult is included to illustrate the Swedish model.

Keywords: broadband policy, regulation, developmental policy, public private partnership.
