A Door bell is a signaling device of your home which is used to indicate the Owner (host) that someone is at your door-step. The problem that is faced today is the touch contact of the Door-bell switch, wherein everyone will have to touch it, not having any other option than knocking or slamming the door. This is a critical issue condition nowadays, when by chance a Corona affected person unintentionally touches the switch, later followed by a healthy person, wherein which it now acts as a source of transmission. A touch less door bell (Buzzer) using sensors will solve this issue, wherein available solutions have Ultrasonic sensors for the same. Similarly this door bell can also produce a strong intensity of signal which can also be used as an alert system, if an intruder is trying to enter, while the host is not in the house. To implement both these together a PIR sensor would additionally be required to enable the Ultrasonic sensor and Sound sensor. The alert system can be controlled by the Host with the help of a Switch placed inside the house. The host is being alerted with a message in both scenarios with the help of a GSM module. All of these controlled by a single microcontroller, and the reuse of PIR and Buzzer, makes it cost effective.

Pulse compression techniques are mostly used for increasing range resolution in radar systems. Stepped Frequency Pulse Train (SFPT) signal is well suitable in pulse compression techniques. The Pulse Repetition Interval (PRI) of the SFPT is varied to avoid the blind speed and in Counter Measures. Here, evolutionary algorithms are used to optimize non-uniform PRI sequence of SFPT signal for getting better resolution. The PSLR( Peak Sidelobe Ratio) and ISLR (Integrated Sidelobe Ratio) are the performance measures of the signal. The non-uniform PRI sequence is optimized by Differential Evolutionary Algorithm (DE) but it has several drawbacks including unstable convergence in the last period and easy to drop into regional optimum. To overcome this, Grasshopper Optimizer Algorithm (GOA) is used in this paper for increasing the PSLR of Non uniform PRI SFPT signal.

Soil stability is a significant criterion in the field of development, for soil which needs adequate steadiness, different adjustment strategies can be embraced. The entrenched methods of soil adjustment regularly utilize such establishing operators like cement. Substitution of solidifying substance with commercial or agriculture outcome is profoundly attractive. Rice husk ash is an extremely prospective agriculture dissipates as pozzolanic materials that bring about a prevalent property after joined with lime. Also, coconut fibre is well known for its durability and high resistance and gives well establishing results when combined with lime and rice husk ash. This study worked on the experimental investigation of clayey soil with admixtures like lime, rice husk ash and coconut fibre. This study included the calculation of properties of the soil as consistency limits and strength characteristics. Clay type of soil is used in this study. In view of compaction, expansion of lime, RHA and coconut fibre diminishes the dry density and expands the moisture content. From the perspective of strength characteristics and economical terms, expansion of 6% lime, 8 % RHA and 1 % coconut fibre are prescribed as ideal value for subgrade soil adjustment.

World Health Organization (WHO) recommends a daily intake of at least 400 grams of fruits and vegetables, to prevent diet related chronic diseases and micronutrient deficiencies. It is essential to ensure the quality of foods consumed by the population on a daily basis. Quality of fruits and vegetables is governed by nutritional level, appearance, flavor and climate. Quality assessment methods should be environment friendly and should also benefit both consumers and farmers by enhancing taste and increasing yield, respectively. Conventionally employed quality assessment methods like bio-chemical analysis, imaging etc. are destructive, inefficient and time consuming. Bio-tissues are made up of cells with selectively permeable cell membranes and this makes them equivalent to resistive-capacitive network. Such a network impedes an alternating current (AC) excitation signal applied to it. This bio-impedance (BI) is measured through LCR meters, impedance analysers and off-the shelf chip based boards. In this work we have developed an accurate, smart and non destructive bio-impedance based quality evaluation technique. BI is measured as magnitude and phase for 7 days for each variety of fruit and vegetable followed by exhaustive frequency (5 kHz-200 kHz), ripening and rot analysis. BI magnitude increases as number of days advance i.e. with ripening and the phase undergoes considerable decrease with rotting. The system is made smart by incorporating an expert system. 178 samples of bio-impedance data are used to train the expert system and supervised classification is done through Random Forest classifier. Any fruit or vegetable can be classified as ’Good’ or ’Bad’ immediately and accurately with a maximum accuracy of 98.57%.

Once upon a time, India is rich in vegetation and agriculture. Now, the current scenario is totally different. Every Indian has been trained to work in different fields. In our day to day life, water has increased its demands in overall world which results in water scarcity. This kind of factors affects the regular plantation fields and home gardening. In this connection, we have proposed a methodology to overcome this problem. In the proposed research, a kit with probes and sensors is developed to measure the moisture and humidity level of plants in order to ensure the required water quantity. A solenoid valve is controlled through automation by pre-setting the values of moisture. If the moisture level goes down below certain value, then the solenoid valve is set to open and the water flows. On keeping the sensors on the top of the soil would not sense the parameters effectively which leads to unreliable results. So, in our suggested 0technique, the sensors are placed just below the soil surface, which is nearby closer to the roots of the plant, for getting the significant outcomes. The humidity sensor measures the humidity present in the air and indicates the probability of rain. This feature helps the farmers and the other gardeners in their routine work. This leads to make our country as green and rich in agriculture. There are two more sensors used viz., the flow sensor for measuring the flow rate as well as the volume of water used and the ultrasonic sensor for measuring the water level in the tank for control purpose. The sensors’ data can be communicated to the remotely located user through digital communication devices such as NodeMCU (Arduino) and Internet of Things - Blynk platform.

There are wide ranges of transformers for voltage stabilizer. The autotransformers used in the voltage stabilizers are designed and constructed under design specifications of standard assumptions. In this work, core components of autotransformer are designed using power rating as only input parameter, nevertheless, taking into consideration of standard assumptions. The bounded area of the flux of magnetic field forms basis for core area of electromagnetic induction of transformer. The core area of the electromagnetic induction and window area of transformer for housing copper windings, thus, have linkage with power rating and e.m.f equation of the transformer. Accordingly, we establish a relationship, in the form of equation, between core area and window area. The product of core area and window is equated to the numerical value of the product that has been determined from the power rating and standard assumptions of other design parameters. With the help of proportional relationship, standard as well as from aspect of desired look of the transformer, between length and breadth of the core area and similarly for window area, the dimensions of the core components of the transformer are designed. The designed parameters are tested for feasibility and a transformer under the designed parameters is constructed to validate the experimental result with the theoretical values of the parameters of the transformer. This design is used to determine accurate dimensions of core components of transformer of desired power rating and desired look. This design aspect minimizes waste of core material in fabrication of core components and help in proper lamination of components such as E & I of the transformer.

Mobile devices often store data in cloud computing storage based on the increasing availability of the users. But security is the major issue in cloud computing. Sensitive information is stored and provided across internet to make sure that the data is protected with security. In this paper, the concept of data privacy is given more importance with regard to the major problem of reducing outsourced data usage. Mobile computing has memory storage and power resources as limitations. But cryptography is a concept which provides some sort of security enhancement that ensures the authentication and the availability of data integrity with confidentiality. Certain algorithms are used for ensuring an increase in security such as AES, DES, and Blowfish. Experimental results are computed and analyzed to level up the performance using cryptographic algorithms. Results are shown in order to assure resistance among the above techniques. Choosing an apt algorithm will quench the requirements of the future.

The soil is stabilized with fly ash and ferric chloride mixtures in this research paper. The Serviceability of the pavement is very tractable to the soil sub-grade properties. For that reason, a weaker sub-grade can be improved by using the most effective stabilization method. Based on the literature review, stabilization with fly ash activated sub grade has been found to be an effective option for improvement of soil properties. Stabilization of the soil is mostly done in soft soils such as organic soil, clayey peat, silt. Some of the wastes used are fly ash, marble dust, foundry sand, rice ash and so on. These materials not only provide an alternative to the use of conventional materials but also help control environmental pollution. In many places, the waste is dumped into the open air, which can be very problematic for the people in the area and the workers working in these areas. Using these waste materials not only reduces pollution but also reduces human credibility on natural resources, leading to a more sustainable process of construction. It was found from the literature that the optimum dose of fly ash and ferric chloride revealed essential enhancement in strength and durability characteristics and declination in the swelling and plasticity properties of the soil. Based on that result, it is suggested that a mixture of fly ash and ferric chloride should be take into consideration a workable option for the stabilization of broad subgrades.

The main objective of this paper presents the analytical evaluation and mathematical modelling of hoop stresses of aluminium 7075 alloys in hydro forming deep drawing of n-sided polygonal cup. It is very important to find the magnitude of these stresses generated within the flange region during the deep drawing process for various n-sided polygonal cups. In the flange region two types of stresses will be generated. When is radial tensile stress, it is taking place radially outward direction from the side of the cup to outer side of the blank material. and other is hoop stress it is compressive. It is perpendicular to the radial lines drawn from the job axis to the side of the blank. It is also parallel or tangential to the blank circumference. These two stresses will be generated within the blank material by the application of punch force.. As compared to the conventional deepdrawing process, hydroforming is very convenient. uniform deformation of the blank taking place throughout out the process.

The biotechnology is widely growing with many technologies, still we see a large gap in real-time implementation of complete blood counting. To increase the resolution and accuracy of the measurements advanced communication DDFS can be used. The elements in Direct Digital Frequency Synthesizers (DDFS) involved are: phase accumulator, a phase to amplitude converter which also called look up table (LUT), a digital to analog converter along with active filter. Direct digital frequency synthesis is a method for generating complex high - frequency waveforms for specific applications. This DDFS generates frequency resolution which makes it ideal components use in radar system, software defined radio, modern wireless communicating system, advanced satellite navigation purpose. Use cases for high frequency we get interrupt with spurious noise, larger ROM size, and high power consumption of DDFS signal. In this paper we are proposing the use of signal generated from DDFS to impedance cytometry in which the number of particles gets detected by getting the output frequency different from the input frequency. Due to use of small frequency range of signal spurious noise, power consumption and ROM size will be less with effective performance.

Mobile Learning also known as mLearning, is a new generation of learning where content which users wants to learn is accessible and available on mobile devices like smart phone and tablets. With the evolution of “world in the pocket” learning becomes much easier and one can start learning on the go. This paper illustrates how mLearning could be a better new way to learn and to interact with the learning content provided and how mLearning is proving to be a better alternative to traditional learning. Learning through traditional methods is not helping students to learn and gain new knowledge wherever and whenever they want and also it’s not that effective. It is also researched that not all mLearning applications are helpful for the students or learners to learn whatever they want, only apps with interactive and user-friendly user interface were found helpful. That’s why mobile learning applications are made with user-friendly user interface. Some practical strategies and methods of implementation of mLearning approach despite of its limitations and challenges were recommended in this paper as well.

This essay aims to present the first results of an ongoing research project devoted to study the evolution of the economic inequality in Catalonia based on different documentary sources and parameters. Here we focus on the strengths and limits of the rich fiscal sources preserved between the 14th and 18th century allowing us an analysis of inequality. This study is limited to the period before 1716 because we do not consider totally reliable connecting data from taxes before this moment, essentially focused on immovable wealth, with those from the Cadastre, which was levied on a wide range of incomes.
Measuring urban inequalities. Spatial patterns of service access in sixteenth-century Leiden
Authors: Van Steensel Arie
Published: June 2020

This contribution develops a broader understanding of well-being in premodern towns and by using digital methods to map social and economic inequalities, thereby drawing on insights from research on socio-spatial equity from urban studies. The key questions are how socio-economic inequality was reflected in the urban social topography and to what extent these spatial patterns reproduced inequality. Taking sixteenth-century Leiden as a case study, the spatial patterns of economic inequality and social segregation in this town are first examined. Next, the level of location-based inequality is explored by mapping and calculating urban spatial patterns of service accessibility.
Feeding inequalities: the role of economic inequalities and the urban market in late medieval food security. The case of fourteenth-century Ghent
Authors: Espeel Stef , Geens Sam
Published: June 2020

Although the Food and Agricultural Organization (FAO) revised their theoretical model of food security for over two decades ago, historians have been slow in adopting these new insights to study pre-modern societies. Showcasing the potential of the holistic approach proposed by the FAO, this paper analyses the evolution of food security in the calamitous fourteenth century in Ghent, one the most populated cities at that time. In the long-term, access to food seem to have bettered during the second half of the century thanks to increased wages, wealth and investments into farmland. While these gains can partly be linked to demographic evolutions, we found no evidence of an often-hypothesized Malthusian ceiling before the Black Death.
Looking for the islands of equality in a sea of inequality. Why did some societies in pre-industrial Europe have relatively low levels of wealth inequality?
Authors: Van Bavel Bas
Published: June 2020

This paper scrutinizes the insights won by recent studies in wealth inequality in pre-industrial Europe. It focuses on the regions and periods where levels of inequality were relatively low, trying to arrive at an inventory of causes of these exceptions. It discusses catastrophic events, colonization and revolution as possible causes, but argues that these only occasionally had a leveling effect, depending on the social and institutional context in which they occurred. Most clearly wealth accumulation was restricted, even by maximums on ownership, where associative organizations held a solid position, and market and state played lesser roles as coordination systems.

Language Learning and Study Abroad: The European Perspective
Authors: Coleman James A.
Published: June 2020

The purpose of the present paper is to describe, for a North American audience, how “study abroad” or “residence abroad” is understood in the European context. Here, it is not merely an educational matter: the historical, geographical and political context of Europe has an important influence on the rationale for student residence abroad and on its organisation. As well as highlighting differences from the American context, the paper will describe features of current practice, focusing particularly on the United Kingdom, for several reasons. Residence abroad has been a compulsory part of most degrees in modern languages in the UK for many years, the UK has larger numbers of students involved in the process, and the evaluation of residence abroad has arguably been more systematic than elsewhere in Europe, where residence abroad is normally optional, is not closely integrated into the degree structure, and (at least until recently) has carried little or no weight within the credit structure of the degree. Finally, I shall review the published research into residence abroad, especially with regard to foreign language proficiency and to intercultural competence. The paper is divided into four sections dealing respectively with the European context, residence abroad in Europe, UK specific information, and research findings.

The relative contribution of shape and colour to object memory
Authors: Reppa Irene , Williams Kate E. , Greville W. James , Saunders Jo
Published: June 2020

The current studies examined the relative contribution of shape and colour in object representations in memory. A great deal of evidence points to the significance of shape in object recognition, with the role of colour being instrumental under certain circumstances. A key but yet unanswered question concerns the contribution of colour relative to shape in mediating retrieval of object representations from memory. Two experiments (N=80) used a new method to probe episodic memory for objects and revealed the relative contribution of colour and shape in recognition memory. Participants viewed pictures of objects from different categories, presented one at a time. During a practice phase, participants performed yes/no recognition with some of the studied objects and their distractors. Unpractised objects shared shape only (Rp–Shape), colour only (Rp–Colour), shape and colour (Rp–Both), or neither shape nor colour (Rp–Neither), with the practised objects. Interference effects in memory between practised and unpractised items were revealed in the forgetting of related unpractised items – retrieval-induced forgetting. Retrieval-induced forgetting was consistently significant for Rp–Shape and Rp–Colour objects. These findings provide converging evidence that colour is an automatically encoded object property, and present new evidence that both shape and colour act simultaneously and effectively to drive retrieval of objects from long-term memory.
Does going abroad benefit my country? Views of highly skilled personnel from Sub Saharan Africa on brain drain-brain circulation

The debate on brain drain-brain circulation has been a long-lasting phenomenon of interest among educators in the field of education, in particular, international and comparative education. This long-lasting debate triggered us to rethink about the effects which the concept has on the source country as well as the destination country. The study explored the perceptions of Highly Skilled Personnel (HSPs) residing in Sub-Saharan Africa on HSPs mobility. Respondents for this study comprised of 43 Sub-Saharan African scholars. Data were collected into two phases. First, all the 43 respondents actively participated in a four-day Online Focused Group Discussion (OFGD) moderated by the researchers. The second phase involved online interviews with 12 members who also participated in the first phase. Findings indicated that the majority of respondents favoured brain circulation. This implies a significant shift from brain drain to brain circulation. The socio-economic and political contexts of countries where respondents came from influenced their responses. We suggest that in the current globalized world, instead of restricting HSPs mobility, Sub-Saharan African countries need to create attractive working environment as a means to retain the best talents and motivate those who left to come back. Furthermore, Sub-Saharan African countries must work with diaspora to improve knowledge and business networks that will enable these countries to improve their economies thereby compensating the cost incurred in educating mobile talents. Finally, brain drain-brain circulation agenda should not be viewed in isolation rather as multidimensional in nature due to its overarching countless influencing factors.
