Abstract Traditional parking systems are challenging and tedious as it is occupied at irregular intervals for various reasons. Without proper design, this could lead to loss of business revenue in commercial establishments. The objective of this study is to implement an IoT-based system to address issues faced by visitors at parking lots. The proposed system would include capabilities that can display the status of availability of the lot it is placed in and will report the status through a web service. This availability status is transmitted through WiFi, which can provide insight into the parking activities of the establishment. This provides valuable data for the use of business analytics. This study highlights the advantages a basic and low-cost IoT-based Smart Parking Lot system could present. This is visualized using custom and open-source parking datasets. These features provide the basis for discussion on future improvements and scalable parking solutions.

Smart Parking

In recent years our world is witnessing a great advent in technology and population. With the increase in population there has been an increase in the number of four wheelers i.e. cars. People need more parking spaces. Car parking is a major problem nowadays. Safe and secure parking is needed. Four different car parking proposals are tried and tested: counter-based, wired-sensor-based, wireless-sensor-based, and image-based. In this paper we test a counter based parking system. Arduino and an electronic circuitry has been used to tackle this problem of parking. It keeps a count of the number of cars in the parking lot and also displays if there are empty spaces. Such parking lot does not require any human presence. It is also cheap and easy to operate.

Parking space is becoming a serious problem due to increasing number of vehicles along with the mismanagement of available parking space. Particularly, in places where sports or artistic events are scheduled, searching for parking space is a major problem. In order to combat this problem, Smart Parking Platform is implemented using sensors to detect when a car enters or leaves a parking lot in order to track capacity and alert drivers about availability of parking space. Inefficient management of parking system effects traffic flow and also leads to wastage of time and fuel. Smart Parking Platform smoothens the parking experience and achieves convenience for users by displaying the status of the parking slots in web browser and guiding drivers towards empty parking slot. In this paper, each parking slot is equipped with an ultrasonic sensor which is interfaced to Arduino UNO microcontroller. Arduino UNO sends the trigger pulse to the ultrasonic sensor. Ultrasonic sensors senses whether the parking slot is empty or occupied and sends the data from echo pin to Arduino UNO, which is programmed in such a way that it processes the data and communicates to Node MCU. The status of the parking spaces is updated in the webpage regularly. The user can access the information regarding parking slots by connecting to the provided network. If a parking slot is empty, it is represented by green block. If it is filled, it is represented by red block. This project aims towards reducing traffic congestion and time while searching for parking space. It can be applicable in places such as convention centers, shopping malls, airports, bus stations, stadiums and theatres.

In 1887 Dutch archivist A. J. Servaas van Rooijen published a transcript of a hand-written copy of an anonymous missive or letter, dated 1631, about a horrific famine and epidemic in Surat, India, and also an important description of the fauna of Mauritius. The missive may have been written by a lawyer acting on behalf of the Dutch East India Company (VOC). It not only gives details about the famine, but also provides a unique insight into the status of endemic and introduced Mauritius species, at a time when the island was mostly uninhabited and used only as a replenishment station by visiting ships. Reports from this period are very rare. Unfortunately, Servaas van Rooijen failed to mention the location of the missive, so its whereabouts remained unknown; as a result, it has only been available as a secondary source. Our recent rediscovery of the original hand-written copy provides details about the events that took place in Surat and Mauritius in 1631–1632. A full English translation of the missive is appended.

Status Of Women

Written almost half a century apart, Rajmohan’s Wife (1864) and The Home and the World (1916) can be read as women centric texts written in colonial India. The plot of both the texts is set in Bengal, the cultural and political centre of colonial India. Rajmohan’s Wife, arguably the first Indian English novel, is one of the first novels to realistically represent ‘Woman’ in the nineteenth century. Set in a newly emerging society of India, it provides an insight into the status of women, their susceptibility and dependence on men. The Home and the World, written at the height of Swadeshi movement in Bengal, presents its woman protagonist in a much progressive space. The paper closely examines these two texts and argues that women enact their agency in relational spaces which leads to the process of their ‘becoming’. The paper analyses this journey of the progress of the self, which starts with Matangini and culminates in Bimala. The paper concludes that women’s journey to emancipation is symbolic of the journey of the nation to independence.

Background: Solid free forming (SFF) technique also called additive manufacturing process is immensely popular for biofabrication owing to its high accuracy, precision and reproducibility. Method: SFF techniques like stereolithography, selective laser sintering, fused deposition modeling, extrusion printing, and inkjet printing create three dimension (3D) structures by layer by layer processing of the material. To achieve desirable results, selection of the appropriate technique is an important aspect and it is based on the nature of biomaterial or bioink to be processed. Result & Conclusion: Alginate is a commonly employed bioink in biofabrication process, attributable to its nontoxic, biodegradable and biocompatible nature; low cost; and tendency to form hydrogel under mild conditions. Furthermore, control on its rheological properties like viscosity and shear thinning, makes this natural anionic polymer an appropriate candidate for many of the SFF techniques. It is endeavoured in the present review to highlight the status of alginate as bioink in various SFF techniques.

BACKGROUND During the Coronavirus Disease 2019 (COVID-19) outbreak, community care facilities (CCF) were set up as temporary out-of-hospital isolation facilities to contain the surge of cases in Singapore. Confined living spaces within CCFs posed an increased risk of communicable disease spread among residents. OBJECTIVE This inspired our healthcare team managing a CCF operation to design a low-cost communicable disease outbreak surveillance system (CDOSS). METHODS Our CDOSS was designed with the following considerations: (1) comprehensiveness, (2) efficiency through passive reconnoitering from electronic medical record (EMR) data, (3) ability to provide spatiotemporal insights, (4) low-cost and (5) ease of use. We used Python to develop a lightweight application – Python-based Communicable Disease Outbreak Surveillance System (PyDOSS) – that was able perform syndromic surveillance and fever monitoring. With minimal user actions, its data pipeline would generate daily control charts and geospatial heat maps of cases from raw EMR data and logged vital signs. PyDOSS was successfully implemented as part of our CCF workflow. We also simulated a gastroenteritis (GE) outbreak to test the effectiveness of the system. RESULTS PyDOSS was used throughout the entire duration of operation; the output was reviewed daily by senior management. No disease outbreaks were identified during our medical operation. In the simulated GE outbreak, PyDOSS was able to effectively detect an outbreak within 24 hours and provided information about cluster progression which could aid in contact tracing. The code for a stock version of PyDOSS has been made publicly available. CONCLUSIONS PyDOSS is an effective surveillance system which was successfully implemented in a real-life medical operation. With the system developed using open-source technology and the code made freely available, it significantly reduces the cost of developing and operating CDOSS and may be useful for similar temporary medical operations, or in resource-limited settings.

The introduction of series capacitors in transmission lines causes problems in terms of reliability and the security of distance protection relays. As distance protection is widely used in the transmission network, the challenge of applying it to series compensated lines has been taken up by utilities and relay manufacturers in various ways. In the field of power system protection, developments are largely driven by relay manufacturers, and are often not published in the academic literature; the status and trend of the relay manufacturer’s development are better found in their product manuals and patent activity. Further insight into specific implementations by transmission utilities can be found from publications in industry-led forums and some academic journals. This article surveys the status and development of distance protection for series compensated lines, with a focus on industrial implementation and practical considerations. Factors that influence the protection of series compensated lines are presented. Implementation examples reported by utilities are summarized as examples of the different situations encountered and the methods used to deal with them. It is observed that many utilities use communication-aided protection in series compensated lines, and distance protection is used with reduced reach. Solutions described in relay manuals are presented to demonstrate the manufacturers’ approaches to problems associated with series capacitor protection. While there are methods to counter voltage inversion, current inversion seems to represent a more serious challenge. A patent overview indicates the trends in this domain to be moving towards time-domain-based faster protection methods.
