In the case of the cloud, for 20,000 and 50,000 tags, periodic high-load intervals occur because of sharing the system and network with other users, which impacted both the sample processing rates shown in Table 4 and the respective latencies included in Table 3. As was previously mentioned in Section 4.1.3, the fact of sharing cloud resources may impact the system performance, but it is not the only factor that affects the system response delay. In order to illustrate such an impact, Figure 23 shows how bandwidth (as measured by iPerf [56], which is the speed rate at which a sample file is transferred) fluctuates during a time interval due to the multiple user interactions through the network and routing/switching devices that exist in the network path that goes from the workshop where RFID readers are emulated until the data reaches the cloud. Although, for clarity, Figure 23 only represents a five-minute interval, bandwidth was measured with iPerf during more than six hours (almost a work shift). The results showed that bandwidth fluctuated constantly between 9.44 and 24.1 Mbps, although most of the time it remained stable within 17 and 20 Mbps (the overall average was 18.42 Mbps and the variance, 2.92 Mbps). Therefore, when designing a real-time positioning service like the one proposed in a cloud-based scenario, the entire path that the data will follow from the RFID readers until the cloud must be taken into account.

TítuloSmart Pipe System for a Shipyard 4 0

TítuloSmart Pipe System for a Shipyard 4 0

After the triumph of the lean production systems in the 1970s, the outsourcing manufacturing phenomenon of the 1990s, and the automation that took off in the 2000s, the fourth major disruption in modern manufacturing is Industry 4.0. This industrial revolution can be defined as the next phase in the digitalization of the sector [1], driven by several emerging technologies: the ubiquitous use of sensors, the stunning rise in data volume, the increasing computational power, and connectivity; the emergence of analytics, cloud computing and business-intelligence capabilities; new forms of human-machine interaction such as augmented-reality systems; and advances in transferring digital instructions to the physical world, such as Cyber-Physical Systems (CPS), Internet of Things (IoT), robotics, and 3-D printing. Most of these technologies are mature and they have been present for some time. Although some of them are not yet ready for a broader application, many are now at a position where their greater reliability and cost-effectiveness are starting to be appealing for industrial applications.

TítuloDesign and Empirical Validation of a Bluetooth 5 Fog Computing Based Industrial CPS Architecture for Intelligent Industry 4 0 Shipyard Workshops

TítuloDesign and Empirical Validation of a Bluetooth 5 Fog Computing Based Industrial CPS Architecture for Intelligent Industry 4 0 Shipyard Workshops

For instance, in the case of shipbuilding, the use of robots has been proposed for optimizing tasks like hull blasting [34] or welding [35]–[39]. Similarly, wireless sensor tech- nologies have been recently used for monitoring shipbuilding tasks. Most of the examples are focused on toxic gases detec- tion [40], or more specifically, the concentration of CO [41]. An example of a safety management monitoring system using sensors and Radio Frequency IDentification (RFID) is pre- sented in [42]. The system, which was designed for a Korean shipyard, proposes a risk-free backward operation of forklift trucks, a driver safety management service, a Green Zone service, and an integrated monitoring service to prevent safety accidents during transportation of pipes for large vessels. A system with a similar purpose is introduced in [43], where the authors propose a LoRaWAN-based smart health, safety and environment system for shipbuilding and onshore plants. In such an article, the use of a LoRa relay is introduced to ensure a higher Signal-to-Noise Ratio (SNR) and improve the packet reception rate both for an underground scenario and confined spaces.

TítuloA fog computing and cloudlet based augmented reality system for the Industry 4 0 shipyard

TítuloA fog computing and cloudlet based augmented reality system for the Industry 4 0 shipyard

Because of the previously mentioned limitations, researchers have modified traditional AR architectures. The most common variation consists in adding local PCs to the network in order to increase computational capabilities. For instance, an interesting work is described in [53], where it is studied how to deploy AR systems in vehicles. Although the researchers state that it is easy to create centralized in-vehicle AR systems when relying on traditional Engine Control Units (ECUs), such an approach derives into an increasing response latency due to the multiple tasks to be carried out (e.g., image acquisition and display, protocol conversions, sensor value collection and processing). Moreover, the researchers indicate that the latest trends in car manufacturing regarding vehicle architecture design prefer to go for architectures divided into domains (for instance, there might be a domain for the powertrain, one for the transmission and another one for chassis control), among which an automotive AR system would distribute its functionality.

TítuloTowards an Autonomous Industry 4 0 Warehouse: A UAV and Blockchain Based System for Inventory and Traceability Applications in Big Data Driven Supply Chain Management

TítuloTowards an Autonomous Industry 4 0 Warehouse: A UAV and Blockchain Based System for Inventory and Traceability Applications in Big Data Driven Supply Chain Management

The performance of OrbitDB was measured in terms of response latency (i.e., how fast the inventory data were inserted into OrbitDB after being sent by a UAV ground station). Three scenarios (named A, B and C) were simulated in order to evaluate the effect of payload size and network delay, so small, medium and large payloads were sent to OrbitDB when it was running either in the same Intranet (i.e., the same private local network) as the ground station, and when it was running in a remote cloud on the Internet (i.e., for simulating the connection with other stakeholders such as suppliers or external audits). As a reference, it can be indicated that the minimum/average/maximum round-trip times to the machine that ran OrbitDB in the Intranet were 0.935/1.034/1.695 ms, while the same values for the connection between the ground station and the remote cloud were 37.948/39.362/51.172 ms. Scenarios A, B and C take place inside an Intranet. Scenario A corresponds exactly to the environment tested in Section 5.2: the inventory data were only 13 Tag IDs, which derived into a very small payload (around 1 KB). Scenarios B and C simulate inventory data of 5000 (around 30 KB) and 10,000 (around 67 KB) items, respectively. Regarding Scenarios D, E and F, they also simulate 13, 5000 and 10,000 items, respectively, but the inventory data is sent from the local network to a remote OrbitDB instance that runs on a cloud on the Internet.

Production planning supported by 4 0 industry tools in the sector of the logistics

Production planning supported by 4 0 industry tools in the sector of the logistics

Once in the warehouse, a series of order preparation operations are carried out. Among them, we can highlight its conformation with the different products required, its packaging, labeling and, subsequently, its location in the warehouse's dispatch area. Finally, we find transport, which was part of the first definition of logistics. However, the need to reduce the delivery time by customers has added new aspects to this section. In addition to dealing purely with transport, logistics must optimize the loads of trucks, the study of the best routes and modes of transport and, finally, the best way to unload the goods in the client.

TítuloDesign, Implementation and Practical Evaluation of an IoT Home Automation System for Fog Computing Applications Based on MQTT and ZigBee WiFi Sensor Nodes

TítuloDesign, Implementation and Practical Evaluation of an IoT Home Automation System for Fog Computing Applications Based on MQTT and ZigBee WiFi Sensor Nodes

An example of a multi-transceiver (X10, Serial, EIB, ZigBee, Bluetooth, DTMF, CAN and GSM/GPRS/UMTS) HAS is presented in [20]. In such a paper, the authors detail an indoor ambient intelligence platform and an IP-based messaging protocol to communicate the home automation controller with the rest of the equipment. Baraka et al. [21] presented a low-cost HAS based on the use of a gateway consisting of an Arduino MEGA with Ethernet and ZigBee shields, and an Android tablet that acted as home controller. The system uses ZigBee for connecting wireless sensor nodes and X10 for wired communications. An Arduino MEGA, an Ethernet shield and an Android phone are also used in [42], but, in this case, the sensors and actuators were connected directly to pins of the Arduino. CONDE [43] is another HAS whose objective is to improve energy efficiency in smart buildings. CONDE is decentralized and thus allows for reducing response time and power consumption with respect to traditional centralized systems. CONDE was tested by using MICAz motes, which were able to lower decision delay times and increase energy savings when evaluating lighting and Heating, Ventilation and Air-Conditioning (HVAC) systems.

TítuloA numerical approach based on the BEM for computing transferred earth potentials in grounding analysis

TítuloA numerical approach based on the BEM for computing transferred earth potentials in grounding analysis

The main goals of a grounding system are to guarantee the integrity of equipment and the continuity of the service under fault conditions and to safeguard that persons working or walking in the surroundings of the grounded installation are not exposed to dangerous electrical shocks. Consequently, the apparent electrical resistance of the earthing system must be low enough to assure that fault currents dissipate mainly through the grounded electrode, while maximum potential differences between close points on the earth surface must be kept under certain tolerances (step, touch and mesh voltages) [1].

e-Report Generator Supporting Communications and Fieldwork: A Practical Case of Electrical Network Expansion Projects

e-Report Generator Supporting Communications and Fieldwork: A Practical Case of Electrical Network Expansion Projects

The Spanish Electrical Network (REE) is the owner of the entire high voltage electric energy transport network in the Spanish territory; it is responsible for its expansion, maintenance and management. The high voltage electric lines located on the territory induce different affections on public and private property land. These affections may be of different types of occupation or easement and should be thoroughly identified on the pertinent documentation to be included into the execution project of these types of infrastructures. Every project is endorsed, approved and processed according to the responsible body corresponding to every particular case; 400 kV installations should be processed according to the requirements of the State Administration; 220 kV installations are handled complying with the requirements of the involved regional governments. This fact implies that the way the projects are presented are not homogeneous since requirements are variable in the Communities and are continuously evolving. This changing situation concerning the requested documentation compels the REE to handle the project data in a structured, standardized way, integrating new processes within consolidated workflow.

Note that the elements of this environment are the nexus between the requirements of the productive environment and the potential capacities of the scientific environment. The agents from the technological and advanced services environment are any provider that brings novel or improved technological solutions, such as frit, glaze and colour providers, machinery providers and varied services providers (design, CAD/CAM, serigraphy, etc.), and diffuses them in the sector. Those firms or service providers from the sector that offer advice in the fields of design, computerization and new technologies, technological and market consultancy, etc. also belong to the technological and advanced services environment. Some ceramics firms (18% according to Fundación BANCAIXA, 1999) had their own internal design department, but most of buy designs for technical studies or obtain them from their providers of frits, glaze and colours or special pieces.

Performance Evaluation of Parallel Computing on Agent-Based Models: The Minority Game Case

Performance Evaluation of Parallel Computing on Agent-Based Models: The Minority Game Case

Abstract: Simulations of agent-based models developed for topics of learning and inductive reasoning in artificial intelligence, social behavior, decision making, etc., are progressively requiring higher power processes while they increase their participation as management and political decisions support. In this work we develop the implementation of the Minority Game Model for HPC platforms in order to analyze the performance of simulations related to contexts of agent-based models for large scales. We compare times to parallel and sequential processes for several instances and get the corresponding speedup. For this work we use the MPI system with a hardware configuration of Master-Worker (Slave) paradigm with a cluster of upto 10 processors as workers. In order to improve efficiency, we evaluate performances for several sizes of clusters varying the size of the instances of the problem and detect optimum configurations for some instances of simulation.

Relaciones entre el Estado y los sindicatos y sus consecuencias en torno al régimen de obras sociales en Argentina: un análisis histórico-político

Relaciones entre el Estado y los sindicatos y sus consecuencias en torno al régimen de obras sociales en Argentina: un análisis histórico-político

General consensus exists on the fact that, after the rise of Perón to the national government, there was a failed attempt to centralize the health system in state hands. The creation of the Secretariat of Public Heath [Secretaría de Salud Pública] (a) in 1946, which depended on the vice-presidential office of Argentina, evidences this assertion. Firstly, establishing this secretariat as autonomous with respect to the Ministry of Home Affairs [Ministerio del Interior de la Nación] conferred a “ministerial status” to its bureaucratic decisions. Secondly, the appointment of Ramón Castillo as its senior member implied a prioritization within the state agenda of those measures the State would take regarding the “health question.” Taking this into consideration, it is evident that the State was affirming the idea that health was a public issue, a concept that had started taking shape in the country first with the hygienists and then with the financial crisis that affected the mutual associations; however, it acquired interna- tional scope especially after the “Beveridge Plan” was published by the British government in 1942. As Arce explains, seeing health as an individual issue had already been widely problematized and the notion of “public health” had taken hold throughout the Western world as a result of the post-war international policy (1 p.106).

Dopamine, Effort Based Choice, and Behavioral Economics: Basic and Translational Research

Dopamine, Effort Based Choice, and Behavioral Economics: Basic and Translational Research

Operant behavior is not only regulated by factors related to the quality or quantity of reinforcement, but also by the work requirements inherent in performing instrumental actions. Moreover, organisms often make effort-related decisions involving economic choices such as cost/benefit analyses. Effort-based decision making is studied using behavioral procedures that offer choices between high-effort options leading to relatively preferred reinforcers vs. low effort/low reward choices. Several neural systems, including the mesolimbic dopamine (DA) system and other brain circuits, are involved in regulating effort-related aspects of motivation. Considerable evidence indicates that mesolimbic DA transmission exerts a bi-directional control over exertion of effort on instrumental behavior tasks. Interference with DA transmission produces a low-effort bias in animals tested on effort-based choice tasks, while increasing DA transmission with drugs such as DA transport blockers tends to enhance selection of high-effort options. The results from these pharmacology studies are corroborated by the findings from recent articles using optogenetic, chemogenetic and physiological techniques. In addition to providing important information about the neural regulation of motivated behavior, effort-based choice tasks are useful for developing animal models of some of the motivational symptoms that are seen in people with various psychiatric and neurological disorders (e.g., depression, schizophrenia, Parkinson’s disease). Studies of effort-based decision making may ultimately contribute to the development of novel drug treatments for motivational dysfunction.

TítuloDesign of a Fog Computing, Blockchain and IoT Based Continuous Glucose Monitoring System for Crowdsourcing mHealth

TítuloDesign of a Fog Computing, Blockchain and IoT Based Continuous Glucose Monitoring System for Crowdsourcing mHealth

Abstract: Diabetes Mellitus, usually called only Diabetes, is a worldwide chronic metabolic disorder that is characterized by abnormal oscillations in blood sugar levels. Such levels should be monitored by diabetes patients, which traditionally have had to take blood samples by finger-pricking, at least between twice and four times a day. Finger-pricking has a number of drawbacks that can be tackled by Continuous Glucose Monitors (CGMs), which are able to determine blood sugar levels throughout the day and not only at specific time instants. In this paper, the design of an IoT CGM-based system is proposed, whose collected blood sugar sample values can be accessed remotely; thus being able to monitor patients, specifically dependent ones (e.g., children, elders, and pregnant women) and warn them in the case where a dangerous situation is detected. In order to create such a system, a fog computing system, based on distributed mobile smart phones, has been devised to collect data from the CGMs. Moreover, the use of a blockchain is proposed, to receive, validate, and store the collected data with the objective of avoiding untrusted sources and, thus, to provide a transparent and trustworthy data source of a population, which can vary in age, ethnicity, psychology, education, self-care, and/or geographic location, in a rapid, flexible, scalable, and low-cost way. These crowdsourced data can enable novel mHealth applications for diagnosis, patient monitoring, or even public health actions, which can help to advance in the control of the disease and raise global awareness on the increasing prevalence of diabetes.
