Enormous growth of population has been observed in recent years and the number of passengers is traveling by the Indian railway has been increased significantly during the pilgrim season due to rapid urbanization. Pedestrian traffic is an important aspect of traffic handled by the Indian railways, because of competitive tariffs with other modes of transports, the comfort of travel, and speed of connectivity. The present study is carried out in the Kerala state railway stations under the categories of A1(NSG2), and A (NSG3) which has the highest annual passenger of boarding and alighting are recorded. Pedestrian flows are taken with the help of recorded video graphic footage on the railway station premises. The studies carried out in the pedestrian parameters and estimate the capacity of pedestrian flow involve a variety of pedestrians such as era, sexuality, belongings carried by the pedestrian, schedule of a train as well at entry and exit passageway of stairways with the help of Indo-HCM 2017 and NFPA 130, 2020 also to analyses the level of service of a pedestrian with the fundamental diagrams of the pedestrian flow vs speed, speed vs density, flow vs density, and space vs speed are developed. The discoveries of this study are expected to be fruitful for civic bodies, railway protection force, policymakers, the public, and other stakeholders to design a solution working on the idea of world elegance railway stations.

Pedestrian Counting

The demand for automatic counting of pedestrians at event sites, buildings, or streets has been increased. Existing systems for counting pedestrians in video sequences have a problem that counting accuracy degrades when many pedestrians coexist and occlusion occurs frequently. In this paper, we introduce a method of clustering optical flows extracted from pedestrians in video frames to improve the counting accuracy. The proposed method counts the number of pedestrians by using pre-learned statistics, based on the strong correlation between the number of optical flow clusters and the actual number of pedestrians. Furthermore, we compare the performance of two algorithms that use Harris corner points and lattice points when optical flows are detected. We confirm that the counting accuracy using feature points is higher than that using lattice points especially when the number of occluded pedestrians increases.

  The obelisk is a large stone block with a height ranging from 50 cm to 3 m. It varies in width from one obelisk to another. It is sculptured from one side or two or four sides with prominent picture inscriptions, often accompanied by cuneiform texts for immortalising kings and their military campaigns. This obelisk is constructed in a rectangular or square, and some of them a dome convex or semi-circular or pyramid. The lower section of the obelisks is wide, similar to the base of the base, and another section is sculpted on a slightly sloping end, so that it can easily be attached to the ground or placed on a special base. The rulers and kings of Mesopotamia established and displayed the obelisk in public places in order to be seen by the public.  It also was placed in the yards of temples or public squares and squares and the streets of cities. It used to celebrate their religious, military and historical achievements in order to immortalise their actions. These obelisks are held to commemorate the deeds of kings and their achievements in peace and war as confirmed by the cuneiform texts and the artistic scenes implemented on them.

AbstractLibel played an important and extraordinary role in early modern conflict culture. The article discusses their functions and the way they were assessed in court. The case study illustrates argumentative spaces and different levels of normative references in libel trials in 16th century electoral Saxony. In 1569, Andreas Langener – in consequence of a long stagnating private conflict – posted several libels against the nobleman Tham Pflugk in different public places in the city of Dresden. Consequently, he was arrested and charged with ‘libelling’. Depending on the reference to conflicting social and legal norms, he had therefore been either threatened with corporal punishment including his execution, or rewarded with laudations. In this case, the act of libelling could be seen as slander, but also as a service to the community, which Langener had informed about potentially harmful transgression of norms. While the common good was the highest maxim, different and sometimes conflicting legally protected interests had to be discussed. The situational decision depended on whether the articulated charges where true and relevant for the public, on the invective language, and especially on the quality and size of the public sphere reached by the libel.

Public art invariably involves the drawing of individuals into the roles of audience and participant by virtue of it being in the public domain – in public places where those individuals are getting on with their everyday lives. As such, a large proportion of the ‘audience’ is an unwitting one, subjected to the art rather than subscribing to it. This is equally true of public sound art, where response to an intervention may vary from engagement to non-engagement to indifference to unawareness, along with a variety of transitional states between. This essay seeks to investigate this ambiguous territory in public sound art, proposing it both as an area rich in possibility for creative exploration and as a means by which artists may reveal and encourage sensitivity to the existing characteristics of a site (thus accommodating the pursuit of agendas relating to acoustic ecology). In particular it investigates and presents a case for the use of lowercase strategies in sound art as ways in which the public might be invited into a dialogue with works (invitation rather than imposition) and thus empowered as partakers of public sound art.

Many are the aspects we should ponder on, after 17 months from the burst of the COVID-19 pandemic, especially as nurses. Due to the numerous cuts to the public health sector in the last decades in Italy, the sanitary emergency has been a great sacrifice for health professionals, as public health was completely unprepared to withstand it. The Italian government reacted to this lack of preparation with exceptionally urgent measures. Although, these measures were implemented long after the initial state of confusion and of inappropriate management, they brought about stability and led to a containment strategy for the spread of the virus across the nation [1]. The reduction in the number of COVID-19 diagnoses was mainly achieved through social distancing. At first this was only required to a small number of communities affected by high infection rates, but was eventually extended to the rest of the country from March 2020 [2]. The national lockdown during the first COVID-19 wave (from March to May 2020), was replaced by regional lockdowns in the second wave (from November 2020). As of now, regional lockdowns are integrated by the vaccine campaign and Green Pass enforcement. In November 2020 the Italian Prime Minister at the time, issued legislative measures to enforce regional lockdowns, limiting nonessential movements, cafes, restaurants and other public places opening hours. This legislation established to classify the national territory in different levels of restriction based on the infection rate: red zones - highest risk of infection, orange zones - medium high risk and yellow zones with a minor risk of infection. A later legislation introduced the white zone for territories with the lowest risk of infection (DPCM-14th January 2021). The infection rate has been important to establish a region’s tier status; however, it is not the defining parameter anymore. A new legislation from July 2021 (n.105 - 23rd July 2021), opted to classify a region’s tier status according to the hospital bed’s occupancy rate for COVID-19 patients in intensive care and other medical areas.

This article examines the way in which the availability of cheaply produced polyester flags has changed the symbolic landscape in the public places of Northern Ireland. The “tradition” of flying flags to express identity is common throughout the world and an important feature of an annual marking of residential and civic spaces in Northern Ireland. Such displays have been a consistent part of the reproduction of political identities through commemoration and the marking of territory. However, the availability of cheaply produced textiles has led to a change in the way the displays take place, the development of a range of new designs and helped sustain the control of areas by particular paramilitary groups. It highlights how the “symbolic capital” of the national flags can be used by different social groups having implication on the status and value of the symbol.

AbstractCOVID-19 is a serious problem that faced by almost all countries in the world. Since announced as a pandemic by WHO on March, the number of positive COVID-19 cases in Indonesia has reached 287,008 patients until the end of September 2020. COVID-19 cases dispersion depends on the local government policies and the awareness of the public to obey. About 60 percent of positive cases and 65 percent of death cases were in Java. Therefore, the aim of this study is to analyze the growth of the COVID-19 case in Java from March to September 2020 in relation to the local government policies. The results showed that six provinces in Java had the same pattern. The large-scale social restriction (PSBB), which was implemented since April 10 2020, seen to be able to contain the dispersion of cases because from April to June the positive cases did not increase significantly. A very high increase occurred in August and September, this was probably due to the easing of the PSBB become new-normal where various public places and facilities have been reopened. Meanwhile, death cases, the number is very high in mid-April and June and late July to September 2020. For cured cases, there was a significant increase in late August to September 2020. The importance of information about the growth of the COVID-19 cases can help government to formulate strategies and policies to prevent the dispersion of COVID-19.Keyword: COVID-19, Pandemic, Java, cases growth AbstrakCOVID-19 merupakan suatu masalah serius yang sedang dihadapi oleh hampir seluruh negara. Sejak diumumkan sebagai pandemi oleh WHO pada Maret lalu, jumlah kasus positif COVID-19 di Indonesia mencapai 287.008 pasien hingga akhir September. Penyebaran kasus COVID-19 sangat bergantung pada kebijakan yang ditetapkan oleh pemerintah serta kesadaran masyarakat untuk mematuhinya. Sebesar 60 persen kasus positif dan 65 persen kasus meninggal berada di Pulau Jawa. Oleh karena itu, tujuan penelitian ini adalah menganalisis perkembangan kasus COVID-19 di Pulau Jawa sejak Bulan Maret-September 2020 dikaitkan dengan kebijakan pemerintah setempat. Hasil penelitian menunjukkan bahwa keenam provinsi memiliki pola yang sama. Pembatasan Sosial Berskala Besar (PSBB) yang dilakukan sejak 10 April 2020 terlihat dapat menahan penyebaran kasus karena pada bulan April-Juni 2020 kasus positif tidak mengalami kenaikan yang signifikan. Kenaikan yang sangat tinggi terjadi pada bulan Agustus dan September 2020, hal ini mungkin disebabkan oleh dilonggarkannya kebijakan PSBB menjadi PSBB Transisi dimana berbagai tempat dan fasilitas umum telah dibuka kembali. Sementara untuk kasus meninggal, angka tertinggi terjadi pada pertengahan April dan Juni serta akhir Juli hingga September 2020. Untuk kasus sembuh, terjadi peningkatan yang signifikan pada akhir Agustus hingga September 2020. Pentingnya informasi tentang perkembangan kasus COVID-19 ini dapat membantu pemerintah daerah untuk membuat strategi dan kebijakan untuk mencegah penyebaran rantai virus COVID-19.Kata Kunci: COVID-19, Pandemi, Jawa, perkembangan kasus

Video Surveillance System uses video cameras to capture images and videos that can be compressed, stored and send to place with the limited set of monitors .Now a Days all the public places such as bank, educational institutions, Offices, Hospitals are equipped with multiple surveillance cameras having overlapping field of view for security and environment monitoring purposes. A Video Summarization is a technique to generate the summary of entire Video Content either by still images or through video skim. The summarized video length should be less than the original video length and it should covers maximum information from the original video. Video summarization studies concentrating on monocular videos cannot be applied directly to multiple-view videos due to redundancy in multiple views. Generating Summary for Surveillance videos is more challenging because, videos Captured by surveillance cameras is long, contains uninteresting events, same scene recorded in different views leading to inter-view dependencies and variation in illuminations. In this paper, we present a survey on the research work carried on video summarization techniques for videos captured through multiple views. The summarized video generated can be used for the analysis of post-accident scenarios, identifying suspicious events, theft in public which supports Crime department for the investigation purposes.
