Expression analysis is a topic covered under affective computing which is under a lot of research inthe field of computer vision. We propose an expression analysis algorithm that utilizes kernel ELMsand CNNs to determine the state of the expression. The expressions include sadness, happiness,fear, anger, disgust, surprise and neutral. The first step is to detect the face in the image and to dothat we use the DPM face detector and for extracting the features we use the VGG face network.Once we have the features of the face selected in the image we use kernel extreme learningmachines (ELM) due to it’s high speed of execution and the accuracy. Seven ELMs are needed toobtain predictors for seven expressions. The prediction is then performed using a fusion networkthat obtains features from two independent networks. Along with the input from the two networks,scores are taken from all the ELM models as input, to enhance accuracy

Humans share a collection of basic and essential emotions that are expressed by facial expressions that seem to be consistent. The automated identification of humanemotion in imageswill be possible due to an algorithm that detects, extracts, and evaluates these facial expressions.The Face detector and recognizer application is a desktop application used to recognize human face emotions by using a computer vision based smart images. It consists of human face detection picture boxes and considers an image as an original image. It climaxes a face skin color, finds high impact area and identifies different emotions of the face from an image. The results of the image are depending upon the separation of Eyes & Lips movement of person. This is done by comparingface embedding vectors. It finds the smart photos focused on computer vision for successful identification of facial emotions in terms of various modes of speech such as smiling, shocking and weeping.

The focus of this work is to design a deeply quantized anomaly detector of oil leaks that may happen at the junction between the wind turbine high-speed shaft and the external bracket of the power generator. We propose a block-based binary shallow echo state network (BBS-ESN) architecture belonging to the reservoir computing (RC) category and, as we believe, it also extends the extreme learning machines (ELM) domain. Furthermore, BBS-ESN performs binary block-based online training using fixed and minimal computational complexity to achieve low power consumption and deployability on an off-the-shelf micro-controller (MCU). This has been achieved through binarization of the images and 1-bit quantization of the network weights and activations. 3D rendering has been used to generate a novel publicly available dataset of photo-realistic images similar to those potentially acquired by image sensors on the field while monitoring the junction, without and with oil leaks. Extensive experimentation has been conducted using a STM32H743ZI2 MCU running at 480 MHz and the results achieved show an accurate identification of anomalies, with a reduced computational cost per image and memory occupancy. Based on the obtained results, we conclude that BBS-ESN is feasible on off-the-shelf 32 bit MCUs. Moreover, the solution is also scalable in the number of image cameras to be deployed and to achieve accurate and fast oil leak detections from different viewpoints.

Yu. F. Samarin’s works are traditionally viewed through the prism of his affiliation with Slavophilism. His view of the state is opposed to the idea of the complex empire based on unequal interaction of the central power with the elite of national districts. At the same time it was important for Samarin to see the nation not as an ethnocultural community, but as classless community of equal citizens, who were in identical position in the face of the emperor. Samarin’s attitude to religion and nationality had pragmatic character and were understood as means for the creation of the uniform communicative space inside the state. This position for the most part conformed with the framework of the national state basic model, however there still existed one fundamental difference. Samarin considered not an individual, but the rural community that owned the land, to be the basic unit of the national state. As the result the model of national state was viewed as the synthesis of modernistic (classlessness, pragmatism, equality) and archaic (communality) features.

This article is a reflection on the role and contribution of the church in a democratic South Africa. The involvement of the church in the struggle against apartheid is revisited briefly. The church has played a pivotal and prominent role in bringing about democracy by being a prophetic voice that could not be silenced even in the face of death. It is in this time of democracy when real transformation is needed to take its course in a realistic way, where the presence of the church has probably been latent and where it has assumed an observer status. A look is taken at the dilemmas facing the church. The church should not be bound and taken captive by any form of loyalty to any political organisation at the expense of the poor and the voiceless. A need for cooperation and partnership between the church and the state is crucial at this time. This paper strives to address the role of the church as a prophetic voice in a democratic South Africa. Radical economic transformation, inequality, corruption, and moral decadence—all these challenges hold the potential to thwart our young democracy and its ideals. Black liberation theology concepts are employed to explore how the church can become prophetically relevant in democracy. Suggestions are made about how the church and the state can best form partnerships. In avoiding taking only a critical stance, the church could fulfil its mandate “in season and out of season” and continue to be a prophetic voice on behalf of ordinary South Africans.

An “explosive extratropical cyclone” is an atmospheric phenomenon that occurs when there is a very rapid drop in central atmospheric pressure. This phenomenon, with its characteristic of rapidly lowering the pressure in its interior, generates very intense winds and for this reason it is called explosive cyclone, bomb cyclone. With gusts recorded of 116 km/h, atmospheric phenomenon – “cyclone bomb” (CB) hit southern Brazil on June 30, the beginning of winter 2020, causing destruction in its influence over. One of the cities most affected was Chapecó, west of the state of Santa Catarina. The satellite images show that the CB generated a low pressure (976 mbar) inside it, generating two atmospheric currents that moved at high speed. In a northwest-southeast direction, Bolivia and Paraguay, crossing the states of Parana and Santa Catarina, and this draft that hit the south of Brazil, which caused the destruction of the affected states.  Another moving to Argentina, southwest-northeast direction, due to high area of high pressure (1022 mbar). Both enhanced the phenomenon.

Chapter 5 discusses the premises of the emergence of the cartel party with the parties’ resilience to any significant modification in the face of the cultural, societal, and political changes of the 1970s–1980s. Parties kept and even increased their hold on institutions and society. They adopted an entropic strategy to counteract challenges coming from a changing external environment. A new gulf with public opinion opened up, since parties demonstrated greater ease with state-centred activities for interest-management through collusive practices in the para-governmental sector, rather than with new social and political options. The emergence of two sets of alternatives, the greens and the populist extreme right, did not produce, in the short run, any impact on intra-party life. The chapter argues that the roots of cartelization reside mainly in the necessitated interpenetration with the state, rather than on inter-party collusion. This move has caught parties in a legitimacy trap.

This chapter charts the “Law of Release,” a new system of rules that replaced the Law of Ransom. These rules were based on treaties signed from 1739 onward, but also on a variety of lesser agreements and unwritten understandings and the Islamic legal tradition. They were renewed frequently, and structured captivity as late as the 1850s. This chapter will explore the basic structures of the Law of Release—how captives were found, released, and sent home, and how slaveowners were convinced, coerced, or compensated to cooperate. I argue that while release was initially limited to Istanbul, and to the most visible captives, it extended both into elite households, and outward along the Ottoman corridors of power. This process tested the limits of the Ottoman state, forcing the state to cooperate with Russian officials for the benefit of both. They did so in the face of resistance from captors.
