Industrial networks are introducing Internet of Things (IoT) technologies in their manufacturing processes in order to enhance existing methods and obtain smarter, greener and more effective processes. Global predictions forecast a massive widespread of IoT technology in industrial sectors in the near future. However, these innovations face several challenges, such as achieving short response times in case of time-critical applications. Concepts like in-network computing or edge computing can provide adequate communication quality for these industrial environments, and data plane programming has been proved as a useful mechanism for their implementation. Specifically, P4 language is used for the definition of the behavior of programmable switches and network elements. This paper presents a solution for industrial IoT (IIoT) network communications to reduce response times using in-network computing through data plane programming and P4. Our solution processes Message Queuing Telemetry Transport (MQTT) packets sent by a sensor in the data plane and generates an alarm in case of exceeding a threshold in the measured value. The implementation has been tested in an experimental facility, using a Netronome SmartNIC as a P4 programmable network device. Response times are reduced by 74% while processing, and delay introduced by the P4 network processing is insignificant.

The Relationship

Modern risk analysis studies of the power system increasingly rely on big datasets, either synthesized, simulated, or real utility data. Particularly in the transmission system, outage events have a strong influence on the reliability, resilience, and security of the overall energy delivery infrastructure. In this paper we analyze historical outage data for transmission system components and discuss the implications of nearby overlapping outages with respect to resilience of the power system. We carry out a risk-based assessment using North American Electric Reliability Corporation (NERC) Transmission Availability Data System (TADS) for the North American bulk power system (BPS). We found that the quantification of nearby unscheduled outage clusters would improve the response times for operators to readjust the system and provide better resilience still under the standard definition of N-1 security. Finally, we propose future steps to investigate the relationship between clusters of outages and their electrical proximity, in order to improve operator actions in the operation horizon.

This article deals with immigrants in Polish economy. The aim of the article is to present the most important research findings, concerning immigrants and enterprises where they are employed. This issue also includes the influence of the COVID-19 pandemic. The authors of this paper focused mostly on Ukrainian immigrants. It has been proven that increase in the number of immigrant workers leads to the growth of the Gross Domestic Product, and contributes to the faster growth in remittances from the Republic of Poland to Ukraine. As a result of the adverse impact of the COVID-19 pandemic on sales, non-employment costs were reduced in the service and industrial sectors. Employment changes were not correlated with company’s situation.  It is worth noting, that because of the COVID-19 pandemic, some companies may be less inclined to recruit immigrants in the near future, and the overall demand for labor may decrease. This is particularly important, because the primary reason for employment people from abroad was the inability to meet labor needs of the citizens of Poland. The majority of immigrants are employed only to perform physical work which does not require qualifications. Large companies show greater interest in the foreign human capital. Over the past five years, there has been an increase in the number of immigrants who declared their intention to stay in Poland for a longer period of time. More than half of the immigrants stay in Poland, with at least, one family member. On this basis, it may be concluded that the number of immigrants willing to settle in Poland is growing.

Newly installed 3.6m DOT at Nainital (Uttarakhand) is a novel facility for the time domain astronomy. Because of the longitudinal advantage of India, it could be used to study new transients reported by a global network of robotic telescopes. Observations with the 4K × 4K CCD Imager at the axial port of the 3.6m DOT will be very helpful in the near future towards understanding the different physical aspects of time-critical events, e.g., Gamma-ray bursts (GRBs), Supernovae, Gravitational wave candidates, etc. Using the Imager with broadband filters (Bessel UBVRI and SDSS ugriz), ~6.5' × 6.5' images could be obtained to attempt various science goals in synergy with other multi-band facilities. In this study, we present an analysis of unpublished R-band data of GRB 171205A/SN 2017iuk spanning between ~12 to 105 days since burst, that observed using the 3.6m DOT with 4K × 4K CCD Imager. In the R-band light curve, a bump appears to start from ~3 days, which shows the peak at ~15 days after the burst, clearly indicates photometric evidence of association of SN with GRB 171205A.

AbstractRR Lyrae variables are the primary standard candles for old stellar populations, and the traditional first step in the definition of the distance scale. Their properties are known on the basis of well-established physical concepts and their calibration is based on several empirical methods. Both aspects are critically reviewed, and their application as distance indicators within the Galaxy and the Local Group are discussed, also in view of the observing facilities that will be available in the near future.

This introductory chapter provides an overview of Japan as an immigrant country. Japan has become an immigrant country de facto. Starting in the 1980s, to stave off economic decline caused by labor shortage and in the name of internationalization, Japan has tried different programs to bring in foreign workers. In 2012, Japan became one of the most liberal states in its policies for granting permanent residency to highly skilled migrants. As a result, the population of foreigners has been rising for the past three decades and is likely to increase significantly in the near future. Why, then, do both the Japanese government and people inside and outside Japan hesitate to accept the discourse of immigration and the reality of its transformation into an immigrant society? This hesitation has to do with Japan's ethno-nationalist self-identity and the widespread myth surrounding its monoethnic nationhood, on the one hand, and the conventional, albeit anachronistic, definition of “immigrant country” and the difficulty for people to associate an immigrant country with an ethno-nationalist one, on the other hand.

Objective To measure and compare the response times to audibly or visually presented alarms in the operating theatre. Methods The time taken by anaesthetists to cancel randomly generated visual and audible false alarms was measured during maintenance of routine anaesthesia. Alarms were generated and times recorded by a laptop computer on the anaesthetic machine. The visual signal was a 15mm diameter red light positioned next to the physiological monitor mounted on top of the machine. The audible alarm was a Sonalert® buzzer of the type incorporated into many medical devices. Results Nineteen anaesthetists provided a total of seventy-two hours of data (887 alarm events). The response times to visual alarms was significantly longer than to audible alarms (P=0.001 Mann Whitney U test). Conclusions The ability of anaesthetists to appreciate changes in patient physiology may be limited by delays in noticing information presented by monitors. The rapid response to the vast majority of alarms indicates a high level of vigilance among the anaesthetists studied. However, this study suggests that it is safer to rely on audible rather than visual alarms when time-critical information such as oxygenation, heart beat and ventilator disconnection is concerned. Visual alarms would appear to be more appropriate for conveying less urgent information.

The Internet Of Things

Today, a wide range of developments and paradigms require the use of embedded systems characterized by restrictions on their computing capacity, consumption, cost, and network connection. The evolution of the Internet of Things (IoT) towards Industrial IoT (IIoT) or the Internet of Multimedia Things (IoMT), its impact within the 4.0 industry, the evolution of cloud computing towards edge or fog computing, also called near-sensor computing, or the increase in the use of embedded vision, are current examples of this trend. One of the most common methods of reducing energy consumption is the use of processor frequency scaling, based on a particular policy. The algorithms to define this policy are intended to obtain good responses to the workloads that occur in smarthphones. There has been no study that allows a correct definition of these algorithms for workloads such as those expected in the above scenarios. This paper presents a method to determine the operating parameters of the dynamic governor algorithm called Interactive, which offers significant improvements in power consumption, without reducing the performance of the application. These improvements depend on the load that the system has to support, so the results are evaluated against three different loads, from higher to lower, showing improvements ranging from 62% to 26%.
