The world knows a constant development of technology applied in different sectors of activities: health, factories, homes, transportation, and others, one of the big axes that take a lot of attention today is the drone’s field. To communicate information a fleet of drones can use different communication architectures: centralized communication architecture, satellite communication architecture, cellular network communication architecture and a specific AdHoc communication architecture called the UAANET drones architecture. In our work we focused specifically on the routing of information inside the UAANET where we analyze and compare the performances of the reactive protocol AODV and the proactive protocol OLSR, when the UAANET use an applications based on the HTTP protocol, the FTP protocol, the database queries, voice application, and video conferencing application.

Service Discovery Protocol

Recently, appliance networks have been widely adopted in many home applications. Usually, an appliance network requires a server. However, as the number of network users increases, there is not only the problem of costs due to extension of the server and the increase in power consumption, but also the problem that the functions of appliances are restricted when the connection to a server is unavailable. This paper presents a hybrid appliance local network (HALN) communication architecture to tackle the problems with server-based appliance networks. The HALN architecture is designed to remove and/or minimize the utilization of servers by offering the capability of communicating directly with other appliance products. The proposed architecture can also be integrated with existing server-based communication architectures. The HALN architecture is based on the simple service discovery protocol (SSDP) and HTTP protocol (RESTful HTTP server/client architecture) technologies. The effectiveness of HALN is experimentally demonstrated using a smartphone and a set of Linux-based Wi-Fi modems on which the functions that can be provided by typical appliances are implemented. Using the proposed architecture, the communication reliability is also improved by 1.6% as compared with that of an existing server-based communication architecture.

The death toll due to highway crashes is increasing at an alarming rate across the globe. Vehicular Ad Hoc Networks (VANETs) have emerged as a promising solution to prevent crashes by enabling collision avoidance applications. However, a robust and stable collision avoidance application is a cross-layer problem that must address a number of key challenges across all layers of a VANET communication architecture. This paper presents and evaluates a novel VANET protocol suite, named Direction-Aware Vehicular Collision Avoidance (DVCA), which covers application, security services, network, and link layers. DVCA is a vehicle-to-vehicle communication architecture that provides enhanced collision probability computation and adaptive preventive measures for cooperative collision avoidance on bi-directional highways. Moreover, DVCA enables secure, in-time, and reliable dissemination of warning messages, which provides adequate time for vehicles to prevent collisions. Simulation and analytical results demonstrate reasonable reduction in collisions by DVCA, as compared with eminent VANET communication architectures.

In vision of searching for the right Unmanned Aerial System (UAS) for a specific mission, there are multiple factors to be considered by the operator such as mission, endurance, type of payload and range of the telemetry and control. This research is focusing on extending control range of the UAS by using 4G-LTE network to enable beyond-line-of-sight flying for the commercial UAS. Major UAS such Global Hawk, Predator MQ-1 are able to fly thousands of kilometers by the use of satellite communication. However, the satellite communication annual license subscription can be very expensive. With this situation in mind, a new type of flight controller with 4G-LTE communication has been developed and tested. Throughout the research, blended-wing-body (BWB) Baseline B2S is used as the platform for technology demonstrator. Result from this analysis has proven that the proposed system is capable to control a UAS from as far as United Kingdom, with a latency less than 881 ms in average. The new added capability can potentially give the commercial UAS community a new horizon to be able to control their UAS from anywhere around the world with the availability of 4G-LTE connection

When the Statute of the Permanent Court of International Justice was drafted by an Advisory Committee of Jurists in 1920, a paramount question was, should a judge of the nationality of a State party to the case sit?The sensitivity of the issue was encapsulated by a report of a committee of the Court in 1927 on the occasion of a revision of the Rules of Court. It observed that: “In the attempt to establish international courts of justice, the fundamental problem always has been, and probably always will be, that of the representation of the litigants in the constitution of the tribunal. Of all influences to which men are subject, none is more powerful, more pervasive, or more subtle, than the tie of allegiance that binds them to the land of their homes and kindred and to the great sources of the honours and preferments for which they are so ready to spend their fortunes and to risk their lives. This fact, known to all the world, the [Court's] Statute frankly recognises and deals with.”1

The United Nations ad hoc tribunals in the former Yugoslavia and Rwanda had primacy over national judicial agents for crimes committed in these countries during the most notorious civil wars and genocide of the 1990s. The UN Charter granted the Security Council the right to establish a tribunal for Yugoslavia in the context of ongoing civil war and against the will of recalcitrant national agents. The Council used that same right to punish individuals responsible for a genocide that it failed earlier to prevent in Rwanda. In both cases the Council delegated a portion of its coercive title to independent tribunal agents, thereby overriding the default locus of punishment in the world order: sovereign states.

The Mind

The reputation of Jonathan Edwards, impressive though it is, rests upon only a fragmentary representation of the range or profundity of his thinking. Harassed by events and controversies, he was forced repeatedly to put aside his real work and to expend his energies in turning out sermons, defenses of the Great Awakening, or theological polemics. Only two of his published books (and those the shortest), The Nature of True Virtue and The End for which God Created the World, were not ad hoc productions. Even The Freedom of the Will is primarily a dispute, aimed at silencing the enemy rather than expounding a philosophy. He died with his Summa still a mass of notes in a bundle of home-made folios, the handwriting barely legible. The conventional estimate that Edwards was America's greatest metaphysical genius is a tribute to his youthful Notes on the Mind — which were a crude forecast of the system at which he labored for the rest of his days — and to a few incidental flashes that illumine his forensic argumentations. The American mind is immeasurably the poorer that he was not permitted to bring into order his accumulated meditations.

<p>This article was formulated based on interviews with 5 (five) trade union confederations from a number of confederations in Indonesia, namely: Konfederasi Serikat Pekerja Nasional (KSPN), Konfederasi Sarikat Buruh Muslimin Indonesia (KSarbumusi), Konfederasi Serikat Buruh Seluruh Indonesia (KSBSI), Konfederasi Serikat Pekerja Indonesia (KSPI), and Konfederasi Kongres Aliansi Serikat Buruh Indonesia (KKASBI). This article seeks to explore the efforts made by the trade union confederation in promoting gender equality - specifically in advancing the agenda for the prevention and elimination of sexual violence in the world of work. This article was compiled based on research with a qualitative approach, with data collection methods through interviews and literature studies. The results of this study found that the confederations interviewed had already set up internal structures that have specific functions on issues related to gender equality, gender-based violence, and women’s empowerment; although still limited and on ad-hoc basis. This research also finds that the role of the trade union confederation is particularly prominent in advocating policies related to sexual violence and gender-based violence in the world of work, such as advocating the Bill on the Elimination of Sexual Violence, and the ratification of the ILO Convention No. 190 on Violence and Harassment.</p>

Abstract. This article discusses aspects of communication architecture for early warning systems (EWS) in general and gives details of the specific communication architecture of an early warning system against tsunamis. While its sensors are the "eyes and ears" of a warning system and enable the system to sense physical effects, its communication links and terminals are its "nerves and mouth" which transport measurements and estimates within the system and eventually warnings towards the affected population. Designing the communication architecture of an EWS against tsunamis is particularly challenging. Its sensors are typically very heterogeneous and spread several thousand kilometers apart. They are often located in remote areas and belong to different organizations. Similarly, the geographic spread of the potentially affected population is wide. Moreover, a failure to deliver a warning has fatal consequences. Yet, the communication infrastructure is likely to be affected by the disaster itself. Based on an analysis of the criticality, vulnerability and availability of communication means, we describe the design and implementation of a communication system that employs both terrestrial and satellite communication links. We believe that many of the issues we encountered during our work in the GITEWS project (German Indonesian Tsunami Early Warning System, Rudloff et al., 2009) on the design and implementation communication architecture are also relevant for other types of warning systems. With this article, we intend to share our insights and lessons learned.
