With the rapid increase in the volume of e-commerce, the security of web-based transactions is of increasing concern. A widespread but dangerously incorrect belief among web users is that all security issues are taken care of when a website uses HTTPS (secure HTTP). While HTTPS does provide security, websites are often developed and deployed in ways that make them and their users vulnerable to hackers. In this article we explore some of these vulnerabilities. We first introduce the key ideas and then provide several experiential learning exercises so that readers can understand the challenges and possible solutions to them in a hands-on manner.

The Impact

With the advances in networking technologies, robots can use the almost unlimited resources of large data centers, overcoming the severe limitations imposed by onboard resources: this is the vision of Cloud Robotics. In this context, we present DewROS, a framework based on the Robot Operating System (ROS) which embodies the three-layer, Dew-Robotics architecture, where computation and storage can be distributed among the robot, the network devices close to it, and the Cloud. After presenting the design and implementation of DewROS, we show its application in a real use-case called SHERPA, which foresees a mixed ground and aerial robotic platform for search and rescue in an alpine environment. We used DewROS to analyze the video acquired by the drones in the Cloud and quickly spot signs of human beings in danger. We perform a wide experimental evaluation using different network technologies and Cloud services from Google and Amazon. We evaluated the impact of several variables on the performance of the system. Our results show that, for example, the video length has a minimal impact on the response time with respect to the video size. In addition, we show that the response time depends on the Round Trip Time (RTT) of the network connection when the video is already loaded into the Cloud provider side. Finally, we present a model of the annotation time that considers the RTT of the connection used to reach the Cloud, discussing results and insights into how to improve current Cloud Robotics applications.

Living Organisms

Wireless sensor networks (WSNs) are key components in the emergent cyber physical systems (CPSs). They may include hundreds of spatially distributed sensors which interact to solve complex tasks going beyond their individual capabilities. Due to the limited capabilities of sensors, sensor actions cannot meet CPS requirements while controlling and coordinating the operations of physical and engineered systems. To overcome these constraints, we explore the ecosystem metaphor for WSNs with the aim of taking advantage of the efficient adaptation behavior and communication mechanisms of living organisms. By mapping these organisms onto sensors and ecosystems onto WSNs, we highlight shortcomings that prevent WSNs from delivering the capabilities of ecosystems at several levels, including structure, topology, goals, communications, and functions. We then propose an agent-based architecture that migrates complex processing tasks outside the physical sensor network while incorporating missing characteristics of autonomy, intelligence, and context awareness to the WSN. Unlike existing works, we use software agents to map WSNs to natural ecosystems and enhance WSN capabilities to take advantage of bioinspired algorithms. We extend our architecture and propose a new intelligent CPS framework where several control levels are embedded in the physical system, thereby allowing agents to support WSNs technologies in enabling CPSs.

Scientific Classification

Urban design is a component of art and science of architecture and an indispensable field of architectural activity. Subsequent to restoration of independence, Lithuania started travelling down the path of democratic urban design of towns and districts, which resulted in an inevitable evolution of concepts as well as mindset. Two decades of independence have passed, yet one could hardly say that everything is clearly and uniformly perceived by all players involved in activities of urban design. There is still a clear lack of common understanding of the object of art and science of urban design. As a branch of science, urban design is still somewhat misplaced in the scientific classification. This article discusses definitions of urban design used in Lithuania and abroad, gives summarised information on the formal position of urban design in documents regulating professional training, and assesses (within the context of the European Union requirements for professional qualifications) the courses on urban design basics taught under the BA degree programme of architecture at the Faculty of Architecture, Vilnius Gediminas Technical University. Santrauka Urbanistika yra sudėtinė architektūros meno ir mokslo dalis bei neatsiejama architektūrinės veiklos sritis. Lietuvai atgavus nepriklausomybę ir einant demokratinio miestų bei rajonų planavimo ir urbanistinio projektavimo keliu, neišvengiamai buvo susidurta su vartojamų sąvokų ir net mąstysenos kaita. Nors prabėgo jau antrasis nepriklausomybės dešimtmetis, tačiau negalime teigti, kad viskas tapo aišku ir vienodai suprantama urbanistikos veiklos srityje. Lietuvoje vis dar yra gilus nesusikalbėjimas dėl urbanistikos meno ir mokslo objekto. Urbanistika kaip mokslo šaka vis dar neturi vietos mokslo klasifikatoriuje. Šiame straipsnyje yra aptariamos Lietuvoje ir užsienyje vartojamos urbanistikos definicijos, apibendrinama formalioji urbanistikos padėtis studijas reglamentuojančiuose dokumentuose, Europos Sąjungos reikalavimų profesinėms kvalifikacijoms kontekste įvertinami dėstomi urbanistinio projektavimo pagrindai VGTU AF architektūros bakalauro studijose.
