Academic literature on the topic 'Chatter indices'

Aim. To study in experiment the possible syndrome of withdrawal after a 30-day peroral use of energetic drinks. Materials and methods.In the groups of laboratory animals, who had caffeine solution (CS) and energetic drink (ED), as the only source of drinking in free access so as to form a stable use, and in the control group of rats, who received purified water (duration of experiment – 4 weeks), one day after the withdrawal there were studied body mass indices, behavioral functions (cognitive processes, anxiety, behaviour) and rectal temperature. Results. The 1.5-2-fold reduction of motor activity in white rats was established; it was reflected in decreased number of postures and crossed squares in the device “open field”.The increase in anxiety level against the background of energetic drink withdrawal was detected in “dark-light camera” with perforations. At the same time, no changes in motor activity and anxiety level were registered in the group of caffeine users. The following characteristic features of withdrawal syndrome as tooth chatter and gnashing, shaking arms and pads, ptosis, were registered in 87.5 %, 75 % and 37.5 %, respectively, in the group of energetic drink users, and 14.3 %, 42.9 %, 28.6 % in the group of caffeine solution users. During a 30-day period of using energetic drink by white rats, there was observed a negative dynamics of their weight. Conclusions. The decrease in motor activity, increase in anxiety level and presence of a number of signs, does not allow excluding the presence of withdrawal syndrome after a long use of energetic drinks, and in most cases, expression of the signs of withdrawal syndrome exceeds that of caffeine. This fact, in our opinion, needs more detailed studying.

Baudelaire’s verse poetry is informed by a pervasive Creole Gothic resonance. Two separate but related topoi, the Undead and the Living Dead, lie at the heart of the collection’s necrological imaginary of slave and zombie labour. It is this Gothic double-trope of death-in-life/life-in-death that activates the Gothic Creole strain running through Les Fleurs du mal. Ironically, those poems that seem to evoke most directly the Creole world that Baudelaire encountered in 1841, firstly in Mauritius and then in Réunion, avoid all evocation of plantation slavery. Conversely, the city poems associate modern metropolitan life with the idea of slavery, representing it as a living death and death as a merely temporary and reversible escape. The collection’s representation of this ‘living death’ foreshadows the construction (by Orlando Patterson, most notably) of transatlantic chattel slavery as ‘social death’. As for the poetic representation of the ‘Undead’, this centres on the figure of the zombie. The zombie is essentially a slave for whom death has proved no guarantee against an endless ‘living death’ of hard labour. If the Creole inflection of Baudelaire’s imagery relates primarily to the realities of industrialized plantation labour and to the chattel slavery on which it was based, it is further reinforced by indices of tropical localisation and of racial difference, more specifically pigmentation. However subliminal its resonance, this Creole Gothic strain guarantees for Baudelaire’s Fleurs du mal a vivid postcolonial afterlife.

Although it prohibited chattel slavery, California permitted the virtual enslavement of Native Americans under the 1850 Act for the Government and Protection of Indians. Scholars have described some of the key components of the Indian Act, but none has provided a systematic examination of the law's labor provisions or examined how individual employers actually used the law. This article does both by offering a careful survey of the Indian Act, followed by a detailed case study focusing on Cave Couts, the owner of Rancho Guajome in San Diego County. The Couts example reveals that the 1850 Act did not simply legalize the exploitation of Indians as prisoners and indentured "apprentices." Perhaps more importantly, it also preserved the system of debt peonage that had �ourished in California under Mexican rule. Not until after the Civil War did California become a truly free state.

Derived from qualitative data collected for a research project based at the Institute of Social and Economic Research at the University of the West Indies, Jamaica, this paper explores classroom gendered responses of High School students in Jamaica, Barbados and St. Vincent and the Grenadines. The account shows how teachers interpret gendered responses as confirmation of natural and necessary differences between male and female pupils. It is these perceived differences which they use to justify the case for single sex education, particularly for males. Conversely the paper argues that male gendered responses are informed by cultural expectations which translate into pedagogical relationships. These expectations reflect a version of masculinity (emerging from the historical experiences of white patriarchal chattel slavery in the West Indies) which equates education with the female side of a male/female dichotomy. The paper explores ways in which schools encourage this version of ‘masculinity’ at the same time as rendering it educationally inappropriate. In doing so the paper addresses issues which have been raised about male educational failure in recent British research.

Although it outlawed chattel slavery, antebellum California permitted the virtual enslavement of Native Americans under the 1850 Act for the Government and Protection of Indians. Drawing data from a rare and valuable cache of Indian indenture records at the Colusa County courthouse and interpreting them through the lens of Henry Bailey's candid pioneer memoir, this article offers a detailed case study of bound Native American labor and Indian slave trafficking in Northern California's Sacramento Valley. While never comprising a majority of the state's rural work force, bound Indian laborers proved essential to California's rise as a major agricultural producer. Compensating for the dearth of white women and children in male-dominated Gold Rush society and providing a vital alternative source of labor in an expensive free wage market, captive Indian farm hands and domestic servants enabled pioneer farm operations and communities to flourish throughout the formative 1850s and 1860s.

Seventeenth-century reports of the suffering of European indentured servants and the fact that many were transported to Barbados against their wishes has led to a growing body of transatlantic popular literature, particularly dealing with the Irish. This literature claims the existence of “white slavery” in Barbados and, essentially, argues that the harsh labor conditions and sufferings of indentured servants were as bad as or even worse than that of enslaved Africans. Though not loudly and publicly proclaimed, for some present-day white Barbadians, as for some Irish and Irish-Americans, the “white slavery” narrative stresses a sense of shared victimization; this sentiment then serves to discredit calls for reparations from the descendants of enslaved Africans in the United States and the former British West Indies. This article provides a detailed examination of the sociolegal distinctions between servitude and slavery, and argues that it is misleading, if not erroneous, to apply the term “slave” to Irish and other indentured servants in early Barbados. While not denying the hardships suffered by indentured servants, referring to white servants as slaves deflects the experiences of millions of persons of African birth or descent. We systematically discuss what we believe are the major sociolegal differences and the implications of these differences between indentured servitude and the chattel slavery that uniquely applied to Africans and their descendants.

When it was first brought to light in 2010, an anonymously authored, unpublished document from 1690, Proposals for the propagating of the Christian Religion, and Converting of Slaves whether Negroes or Indians in the English plantations, appeared to support claims for an emerging humanitarian sensibility among Christian antislavery reformers in seventeenth-century England. This article argues that Scottish Covenanter, colonizer, and enslaver William Dunlop was the author of these proposals. Dunlop's authorship casts them in a new light, showing the complex ways Christianity and slavery were entangled in this period and the challenges Reformed Protestants faced in their attempts to disentangle them. Dunlop's Reformed background and experience in the Presbyterian resistance movement during the “killing times” of the early 1680s led him to view slavery as anti-Christian tyranny and liberty as the will of God. But during his time in Carolina he was deeply implicated in enslaving illegally seized Christian Indian captives, African chattel slaves, white indentured servants seeking freedom in Spanish Catholic Florida, and even fellow Covenanters banished to the plantations for their resistance to episcopacy. Dunlop's proposals emerged from these dual contexts. They tried and failed to imagine a form of Christian slavery that gave enough freedom to enslaved people to lead authentic Christian lives, showing instead that Christianity and slavery were incompatible and offering reformers only a stark choice: not Christian slavery, but Christianity or slavery.

Arambam Saroj Nalini was born in Imphal, in the then princely state of Manipur, on June 2nd 1933. Her father was a well-known and respected educationalist and government officer. During the war years he was posted to Jiribam, where she received her first education, and later transferred to a convent school in Haflong. She proceeded to Calcutta University, where she became the first Meetei woman to obtain BA and MA degrees, majoring in Philosophy. While in Calcutta she enjoyed close friendship with Christian Naga students, and converted to Christianity. She was baptised at the Lower Circular Road Baptist church, whose minister, Walter Corlett had himself served in Imphal during the war years. The Christian faith was to become a dominant influence on her future life. She came to Britain in the late 1950s to study theology, and obtained a Bachelor of Divinity degree from London University in 1961. Shortly after she married John Parratt. When their desire to work in India was frustrated they decided to work elsewhere in the developing world, initially in Nigeria, where Saroj became a tutor in philosophy at the University of Ile-Ife. When her husband was offered a research fellowship by the Australian National University she enrolled for a PhD in the Department of Asian Studies there, under the supervision of the eminent indologist A.L.Basham. Despite the frequent absences of her husband on field work in Papua-New Guinea and having to care for three young children, the bulk of the thesis was completed before she returned to Manipur for further extended field work in 1972. The doctorate was awarded three years later, one of her examiners being Professor Suniti Kumar Chatterji, who (unusually for the time) himself had a deep interest in India's north-eastern region. Her thesis was published in 1980 (Firma KLM, Calcutta) as The Religion of Manipur. It marked the beginning of a new phase in writing on Manipur by its rigorous application of critical methodology both in the collection and in the analysis of field data, and had considerable influence on younger Meetei scholars.

The main aim of the activity is to develop models and methods for chatter avoidance and control. An analytical plunge milling model will be presented and described, starting from the few literature existing papers. New method for cutting coefficients measurement is introduced, as well together with a more accurate configuration description and the solution algorithm in order to achieve the Stability Lobes Diagrams. The second part of this thesis is focused on developing an active control logic, to be used in a general milling application and able to recognize the milling phase (example air cutting, stable or unstable cut) based on acoustical analysis.

This chapter builds on the critique of the Atlantic world paradigm initiated in the previous chapters. It begins in Haiti, where revolutionary leaders like Jean-Jacques Dessalines opposed not only chattel slavery but also “political slavery,” or subjection to the absolute rule of a foreign conqueror — namely, colonialism. From classical antiquity through the Age of Revolutions, political slavery was associated with Asia and Oriental despotism. This helps explain why eighteenth-century writers ubiquitously associated slavery with India even while they denied that actual chattel slavery was practiced there. The chapter traces the circuit of political slavery and Oriental despotism's global travels, around the world and in the “world” of metropolitan print.

This chapter explores the Theosophical Society’s association with the Bengal Renaissance in India, which is a significant, yet quite unexplored, dimension of both movements. The chapter traces the rise and fall of Theosophical influence in Bengal, beginning with contacts between Bengali and American spiritualists in the early 1870s prior to the formation of the Theosophical Society. Two years before its move to India, the Society established correspondence with leaders of the Brahmo Samaj. After the move to India in 1879, personal contacts were developed through the travels to Bengal of Henry Steel Olcott and Helena Petrovna Blavatsky and the subsequent involvement of Bengalis in the Madras Theosophical Society headquarters. The role of Mohini Chatterji as an emissary of the Theosophical Society to Europe and America was the high point of this association, but by the early twentieth century, Aurobindo Ghose described the Theosophical Society as having lost its appeal to progressive young Indians.

The kind of environment you wish to establish in your classroom is an individual decision that is in part determined by your particular personality and what makes you feel most comfortable. Some teachers prefer a very relaxed environment while others prefer a more controlled environment. Regardless of which approach most appeals to you, you must consider what will be most effective in helping the majority of students to be attentive and productive during class time. In a studio class in which most students are college freshmen right out of high school, you may find it beneficial to keep a tighter rein on things since there seems to be a tendency for the atmosphere to escalate to noisy and chaotic if boundaries are not clearly established and adhered to. In a studio class in which the majority of students are older or more experienced, it will generally not be necessary to monitor things quite so closely. This reflects the simple fact that older students tend to be more mature and often take their studies more seriously. Of course this is a generalization that does not apply to all students, regardless of age or experience. You must gauge the situation and conduct yourself accordingly. Experience indicates that if the atmosphere is too unstructured, with a lot of noise and chatter unrelated to the work being pursued, it is difficult for students to concentrate and to maximize their learning experience. It is therefore a good idea to make it very clear when it is okay to be a bit more relaxed or playful and interactive with fellow students, and when it is time to buckle down and get to some serious work and maintain an atmosphere conducive to this. When working with a model in a life drawing course, certain guidelines should be followed to insure a mutually comfortable and respectful atmosphere for the students and the model. These guidelines are discussed in chapter two under “Classroom Etiquette for Working with a Nude Model.”

Applications of spindle integrated force sensors are examined where the cutting forces are reconstructed from the piezoelectric force sensors that are imbedded in the spindle housing. The reconstruction of the cutting forces using the disturbance Kalman filter effectively provides the high bandwidth sensor requirements. The three applications that are presented in this paper are Adaptive Control with Constraint (ACC), chatter detection, and tool breakage detection, all using the spindle integrated sensors. ACC provides effective means of increasing machining productivity through the adjustment of feed rates by constraining cutting forces. The detection of chatter vibration in machining operations is important in order to ensure quality surface finishes. The cutting forces measured from the spindle sensors provide sufficient information as to whether the cutting operations are stable or not. Tool breakage detection is performed using both a good tool and a damaged tool. Two residual indices based on the first order auto-regressive (AR) filter are examined to determine tool breakage. The experiments verify the successful monitoring strategies using the spindle integrated force sensors.

The main drawback of the high speed milling of monolithic parts for the aerospace industry is the high buy-to-fly ratio that leads to a huge material waste. This problem is caused by the need to stiffen the part during the machining in order to avoid chatter, excessive vibration and residual stresses. The present work proposes a methodology for the milling of compliant parts based on the selection of cutting conditions free of chatter. First, the modal parameters of the part in the most problematic stages of the machining are calculated by means of the finite elements method. Secondly, a three-dimensional stability model is used in each stage to calculate a three-dimensional stability lobes diagram dependent on the tool position along the whole tool path. Given the fact that the depth of cut is defined by the bulk of material, the three-dimensional stability diagram can be reduced to a two-dimensional one, which relates tool position during the machining and spindle speed, and indicates how to change the spindle speed in order to avoid the unstable areas. What is more, the proposed methodology can also be used to dimension the bulk of material, select the proper tool or improve the fixturing of the part. Finally, the methodology is validated experimentally on a test part.
