Yes / Concrete structures in sewer systems, marine engineering, underground engineering and other humid environments are easily subjected to microbial attachment, colonization and, eventually, deterioration. With careful selection and treatment, some additives including inorganic and organic antimicrobial agents were found to be able to endow concrete with excellent antimicrobial performance. This paper reviews various types of antimicrobial concrete fabricated with different types of antimicrobial agents. The classification and methods of applying antimicrobial agents into concrete are briefly introduced. The antimicrobial and mechanical properties as well as mass/weight loss of concrete incorporating antimicrobial agents are summarised. Applications reported in this field are presented and future research opportunities and challenges of antimicrobial concrete are also discussed in this review. / National Science Foundation of China (51908103 and 51978127), China Postdoctoral Science Foundation (2019M651116)

<p> Browsers are used as a medium to perform various activities on the Internet and mobile applications are used on mobile devices. They let users connect to the Internet and access different services such as sending emails, watching videos, using banking services, etc. The increase in the usage of the Internet, personal computers, and mobile phones led financial institutions to democratize their services and provide omnipresent and cost-effective services to their customers, in turn attracting a large customer base. Many of these financial institu?tions store and manage sensitive user information such as account numbers and usernames, passwords, Social Security Numbers (SSNs), etc. Due to the nature of the sensitive infor?mation that these institutions manage, it makes a perfect bait for attackers to exploit and perform cyber attacks. Most of the forensic and security research observed in the bank?ing ecosystem focused on foreign financial institutions and mobile banking applications for Android. However, no forensic research has been conducted on the mobile and browser ap?plications of US financial institutions. In this research, I performed a forensic analysis on both browser and mobile applications (both Android and iOS) of US financial institutions. I conducted a forensic investigation on the JP Morgan Chase (Chase), Purdue Federal Credit Union (PFCU), Discover, and CapitalOne banks. This research found what information these banking applications store locally and where they store them to assist digital forensic investigators in investigations. </p>

Le co-clustering est une technique de classification consistant à réaliser une partition simultanée des lignes et des colonnes d'une matrice de données. Parmi les approches existantes, MODL permet de traiter des données volumineuses et de réaliser une partition de plusieurs variables, continues ou nominales. Nous utilisons cette approche comme référence dans l'ensemble des travaux de la thèse et montrons la diversité des problèmes de data mining pouvant être traités, comme le partitionnement de graphes, de graphes temporels ou encore le clustering de courbes. L'approche MODL permet d'obtenir des résultats fins sur des données volumineuses, ce qui les rend difficilement interprétables. Des outils d'analyse exploratoire sont alors nécessaires pour les exploiter. Afin de guider l'utilisateur dans l'interprétation de tels résultats, nous définissons plusieurs outils consistant à simplifier des résultats fins afin d'en avoir une interprétation globale, à détecter les clusters remarquables, à déterminer les valeurs représentatives de leurs clusters et enfin à visualiser les résultats. Les comportements asymptotiques de ces outils d'analyse exploratoire sont étudiés afin de faire le lien avec les approches existantes. Enfin une application sur des comptes-rendus d'appels de l'opérateur Orange, collectés en Côte d'Ivoire, montre l'intérêt de l'approche et des outils d'analyse exploratoire dans un contexte industriel.

Mobile applications can be developed using a variety of different techniques and technologies. One of the most recent of these techniques is the Progressive Web Application (PWA), a cross-platform solution that is built exclusively using common web technologies. The technique has great potential to become a major competitor to native applications but is currently held back by a few rather significant limitations. This project was initiated because of a significant lack of academic research on the topic of PWA, and a perceived poor level of knowledge in the industry about the technique. The goal of the project was to determine if PWA deserved broader utilization or if the current low level of adoption was justified. During the project, two surveys were conducted. The first survey asked mobile application developers from companies in different countries about things such as their knowledge of, experience with, and opinions of PWA. The second survey asked similar questions but was instead answered by lecturers in higher education in Sweden only. The results of this project show that the average level of knowledge of PWAis very low and that developers’ opinions of the technique are quite negative. The limitations of PWA were found to be few but crippling to its potential to achieve widespread adoption.

Humanist thinking on development embraces a people-centred view in which people are considered active agents for change in society. However, the nature and success of public participation in development is a contentious and widely debated issue in international planning and development literature. Simultaneously, realities in planning practice such as the effectiveness and influence of public participation on decision making seems to be daunting. In South Africa public participation is a constitutional right and enforced by planning legislation. Although post-apartheid South African legislation devised strategies to increase the participation of the public on all spheres of government, the nature of participation seems to be contradictive and regarded by numerous authors to be ad hoc, incremental, unstructured, unbalanced and uncoordinated. While good intentions were laid by the Constitution and development legislation and policies, these documents do not necessarily ensure effectiveness of participation, nor create a culture of participation. The aims of the research were thus twofold: firstly, to determine the outcome of public participation in planning applications and secondly, to evaluate the effectiveness of public participation against the background of the current legislative framework in order to enable a greater inclusion of participation in planning. The research followed a quantitative approach and included an in-depth study of statutory town planning applications in Tlokwe Local Municipality completed over a period of sixteen years. The inclusion of both periods before and after democratisation in South Africa shed some light on whether the effectiveness of public participation increased or declined during this period. A database was compiled on the detail of applications and included the type of application, location, legislation involved, public participation involved, objections (if any), rebuttals on objections and the outcome of the application. To organise and summarize the raw data gathered, a descriptive statistical analysis was undertaken. Although participation of the public is needed in town planning applications and enforced by legislation in South Africa, the public’s view that their contribution through objections is not effective was negated by the research. For example, objections (as one indication of the effectiveness of public participation) did not feature prominently (only 6, 3% of applications had objections), but these showed efficacy to influence the outcome of the applications. Overall this research provided a first step towards a better understanding of the effectiveness of public participation towards improved and more inclusive decision making. / MArt et Scien (Urban and Regional planning), North-West University, Potchefstroom Campus, 2015

Published Article / Long-term growth in the additive fabrication industry will come from designs that are difficult, time-consuming, costly, or impossible to produce using standard techniques. Growth will occur with advances in the current additive processes, coupled with breakthroughs in new materials, which are expected to emerge over the next five to 10 years. These advanced materials will better satisfy the design requirements of many new products. The paper considers currently available technologies and discusses recent advancements in direct metal freeform fabrication and its potential of revolutionising the medical industry.
