What robots want? Hearing the inner voice of a robot.
2021
Summary The inner speech is thoroughly studied in humans, and it represents an interdisciplinary research issue involving psychology, neuroscience, and pedagogy. A few papers only, mostly theoretical, analyze the role of inner speech in robots. The present study investigates the potential of the robot's inner speech while cooperating with human partners. A cognitive architecture is designed and integrated with standard robot routines into a complex framework. Two threads of interaction are discussed by setting the robot operations with and without inner speech. Thanks to the robotic self-dialog, the partner can easily trace the robot's processes. Moreover, the robot can better solve conflic…
Aggression and violence among drivers
2001
The invention of assembly line manufacturing, together with the generalised and massive use of the private automobile, has transformed motor vehicles from simply being a mode of transportation to encompass and symbolise a new lifestyle and social order1. Unfortunately, as in many other facets of modern society, the driving environment is not exempt from the expression of violent behaviour2–3. Because the root of driving is found in the lifestyle of a society, this way of life not only dictates the use of motor vehicles but also the way in which they are used4.
A tribute to Juan Rosai
2021
On July 7, 2020 the world of Surgical Pathology lost one of the brightest minds ever: Prof. Juan Rosai.It certainly happened to many of us while approaching a difficult case to exclaim: - This is a case for Juan Rosai! This simple expression synthesizes the legend that was created around him.Those who knew him personally were undoubtedly amazed by his diagnostic insight, exceptional memory and organizational skills.However, his vast culture and passions were not limited to medicine, but ranged to music, literature and the world of sports, especially football.We worked with him in his last years of activity and want to share with the communities of pathologists our warm feelings about this …
I disegni di Rosario Gagliardi conservati presso il Dipartimento di Architettura di Palermo
2020
The Department of Architecture of Palermo keeps some drawings related to the activity of one of the greatest architects to have worked in Sicily in the eighteenth century: Rosario Gagliardi (Syracuse, ca. 1690-Noto, 1762). The importance of the small corpus - coming from a collection already constituted in the 18th century (the Mazza Collection) - is also linked to the fact that the drawings include famous edifices of Sicilian Baroque architecture: from the cathedral of San Giorgio in Ragusa to the churches of Santa Chiara and San Domenico in Noto. The thorough examination of the drawings offers the opportunity for a more general reflection on the characteristics of architectural design in …
Cost-Efficient On-Chip Routing Implementations for CMP and MPSoC Systems
2011
[EN] The high-performance computing domain is enriching with the inclusion of networks-on-chip (NoCs) as a key component of many-core (CMPs or MPSoCs) architectures. NoCs face the communication scalability challenge while meeting tight power, area, and latency constraints. Designers must address new challenges that were not present before. Defective components, the enhancement of application-level parallelism, or power-aware techniques may break topology regularity, thus, efficient routing becomes a challenge. This paper presents universal logic-based distributed routing (uLBDR), an efficient logic-based mechanism that adapts to any irregular topology derived from 2-D meshes, instead of usi…
Fault-Tolerant Application-Specific Topology-Based NoC and Its Prototype on an FPGA
2021
Application-Specific Networks-on-Chips (ASNoCs) are suitable communication platforms for meeting current application requirements. Interconnection links are the primary components involved in communication between the cores of an ASNoC design. The integration density in ASNoC increases with continuous scaling down of the transistor size. Excessive integration density in ASNoC can result in the formation of thermal hotspots, which can cause a system to fail permanently. As a result, fault-tolerant techniques are required to address the permanent faults in interconnection links of an ASNoC design. By taking into account link faults in the topology, this paper introduces a fault-tolerant appli…
Flexible Spare Core Placement in Torus Topology based NoCs and its validation on an FPGA
2021
In the nano-scale era, Network-on-Chip (NoC) interconnection paradigm has gained importance to abide by the communication challenges in Chip Multi-Processors (CMPs). With increased integration density on CMPs, NoC components namely cores, routers, and links are susceptible to failures. Therefore, to improve system reliability, there is a need for efficient fault-tolerant techniques that mitigate permanent faults in NoC based CMPs. There exists several fault-tolerant techniques that address the permanent faults in application cores while placing the spare cores onto NoC topologies. However, these techniques are limited to Mesh topology based NoCs. There are few approaches that have realized …
A TDMA-Based MAC Protocol Supporting Cooperative Communications in Wireless Mesh Networks
2011
This paper proposes a TDMA-based medium access control protocol which enables cooperative communications in multi-hop wireless mesh networks. According to the proposed scheme, each router at the two-hop neighbourhood of each other is allocated to a specific time slot for accommodating either direct or cooperative transmissions in a coordinated manner, controlled by mini-slots which are part of the time slot. Benefiting from the elaborate mini-slot design, channel resources are fairly and efficiently allocated to each router so that no handshake is needed prior to each packet transmission. By providing access priority to cooperative transmission through an optimal relay which is determined b…
Design and Implementation of ForCES Protocol
2017
This paper proposes the design and implementation of the ForCES protocol, specifically FP logical point of the ForCES architecture, which is strictly the communication between the CE (Control Element) and the FE (Forwarding Element). It is a flexible and reprogrammable architecture that is established within the specifications issued and defined by the ForCES working group, and consists of elaboration of a protocol that carries information between both elements. In order to comprobate the correct functioning of the implemented the ForCES protocol, is we provide a network testbed scenario, which consist an application client-server. Each device has equipped with the application which based o…
Computer networks stability independence of the queuing delays
2015
Communication in intelligent computer networks is an indispensible attribute of the dataflow quality in Web traffic. We propose a model that investigates intelligent computer networks stability while specifying its limits. Packet queuing delay affects the performance of the network, and especially its stability. If the network is presented as a dynamic system in block diagram form, we compute a transfer function and determine the quasi-polynomial system. The characteristic polynomial distribution of zeros of complex variable quasi-plane determines the boundaries of the network stability. The approach relies on estimation of the network system's transfer functions and its quasi-polynomial. C…
