Aztec Religion and Gods of the Ancient Mexica

Aztec Religion and Gods of the Ancient Mexica The Aztec religion was made up of a complex set of beliefs, rituals and gods that helped the Aztec/Mexica to make sense of their worlds physical reality, and the existence of life and death. The Aztecs believed in a multiple-deity universe, with different gods who reigned over different aspects of Aztec society, serving and responding to Aztec specific needs. That structure was deeply rooted in a widespread Mesoamerican tradition in which concepts of the cosmos, world, and nature were shared across most of the prehistoric societies in the southern third of North America. In general, the Aztecs perceived the world as divided into and balanced by a series of opposing states, binary oppositions such as hot and cold, dry and wet, day and night, light and dark. The role of humans was to maintain this balance by practicing appropriate ceremonies and sacrifices. The Aztec Universe The Aztecs believed that the universe was divided into three parts: the heavens above, the world in which they lived, and the underworld. The world, called Tlaltipac, was conceived as a disk located in the middle of the universe. The three levels, heaven, world, and underworld, were connected through a central axis, or axis mundi. For the Mexica, this central axis was represented on earth by the Templo Mayor, the Main Temple located at the center of the sacred precinct of Mexico- Tenochtitlan. The Multiple Diety UniverseThe Aztec Heaven and underworld were also conceived as divided into different levels, respectively thirteen and nine, and each of these was overlooked by a separate deity. Each human activity, as well as the natural elements, had their own patron deity who overlooked different aspect of human life: childbirth, commerce, agriculture, as well as the seasonal cycles, landscape features, rain, etc. The importance of connecting and controlling the cycles of nature, such as the sun and moon cycles, with human activities, resulted in the use, in the pan-Mesoamerican tradition of sophisticated calendars which were consulted by priests and specialists. Aztec Gods The prominent Aztec scholar Henry B. Nicholson classified the numerous Aztec gods in three groups: celestial and creator deities, gods of fertility, agriculture and water and deities of war and sacrifices.

M13 Comparative Law in a Global development Context Essay

M13 Comparative Law in a Global development Context - Essay Example Legal systems within the national levels and the lawyers as well as the judges administering such legal systems seem to be destined to interact with unfamiliar legal systems within national, regional, and super-national levels/nature in various ways that are typically multi-faceted. The associated trends and the resulting developments are therefore found to exert a significant effect on the legal environments in any region. There is thus the need for traditional doctrinal curriculum to create a balance through offerings, which would enhance young lawyers’ perspectives by instilling the practical appreciation of the prevailing comparative issues in them. This paper specifically identifies the various issues within the context of comparative methods of dispute settlement in a Global Development Context. Usually, any parties to a given dispute are under the duty of settling the dispute peacefully according to Article 2 of the UN Charter. The parties are expected to remain in principle for the dispute settlement. The parties are also free to make decisions on particular dispute settlement means that they prefer, especially in the absence of a specific treaty obligation according to Article 33 of the UN Charter. All settlements in this category depends inevitably on the parties’ agreement. In this regard, international dispute settlements are accompanied by inherent tensions between the legal duties to peaceful dispute settlements and the absence of real and compulsory mechanism for rendering such obligate effective. According to Menski, in Ãâ€"rà ¼cà ¼ and Nelken (2007:213), â€Å"Non-European informal methods of dispute settlement might resemble healing rituals rather than legal processes, but they are just as powerful as formal legal mechanisms.† This assertion is certainly true to a great extent since the settlement of disputes covers a wide range of settlement devices. Typically, there is a complex relationship between law and religion and that is why the

London Residential Property Market Assignment Example | Topics and Well Written Essays - 2000 words

London Residential Property Market - Assignment Example It affects almost our entire lives, from the quality of our lives, our health and well-being; it determines not only our choice of transportation means but also our choice of work, and status (Baker 2003). Housing also affects our economic wellbeing, family structure, choice of friends and status in the society. It is with no wonder that, Abraham Maslow classified it under basic need of shelter in his social pyramid. Most often, investors see valuation as the first step toward intelligent investing. It has been argued (e.g. Penman 2003) that an investor can make informed decisions about where to invest once the value of shares are determine based upon the fundamentals. This is so because, without this value investors can either buy high or sell low. Investors who trade on these stocks are often forced to ask themselves whether they are buying or selling at the right price. (Penman, 2003). In the face of this situation and their quest for an alternate answer, investors turn to various media including internet chat rooms, printed press, "talking heads" on television. ). In addition, investors consult investment analysts who provide an almost endless stream of information and recommendations to sort out. There are often claims that some shares are undervalued and vice versa. (Penman, 2003). Against this background, the aim of this paper is to carry out an analysis of the United Kingdom London residential markets so as to enable investors make informed decisions as to a buy, a hold or sell decision. The next section provides an overview of the London residential markets. 1.1.2 Overview of the London Residential Market Property prices in United States, the US began falling in 2005 making sub-prime mortgage loans more risky as the borrowers are normally expected to exercise their options to default. Consequently, the US subprime mortgage market is suffering from foreclosures arising from falling real estate prices and borrowers exercising their options to default. (Schumer and Maloney, 2007). Investment banks such as Merrill Lynch, Goldman Sachs and CitiGroup all fortune 500 companies have witnessed significant declines in profits, share prices and are planning to lay off workers as a result of the sub-prime crises. (Ellis, 2007). With regard to the United Kingdom UK particularly London, large empirical literature examined the determinants of the two booms experienced by home prices in the early 1970s and the 80s. Findings from these studies provide tentative evidence in support of the view that speculation on expected future house prices must have been an important force driving actual house prices (Muellbauer & Murphy 1997). Concerns over an ongoing house price bubble in the UK have been repeatedly raised by both the press and policy makers. Over the last thirty years, UK house prices have risen in real terms by around 2 % a year and according to HM Treasury (2003) report this stands in contrast to other European countries such as Sweden, France, and Germany where real house prices have decline or remain

Transmission Of A Tv Signal English Language Essay

Transmission Of A Tv Signal English Language Essay In electronics, many different types of carrier signals exists and due to the fact that this signals simply carry data intended for a different audience, which most of the times, are farther than the area of production of such signals. This gave rise to various modulation techniques to ensure effective transfer of these signals bearing information without loss of quality or degradation. This paper deals on how to modulate a Television (TV) signal using 16-QAM (Quadrature Amplitude Modulation) Keywords include: 16-QAM, TV Signals, Amplitude Modulation, Data, and Attenuation, baseband. 1.0 Introduction Everyday different types of signals transverse the air around us, most of which we cant feel or see, but we see their impact or influence everyday through different electronic gadgets we have or own personally. Most of these electronic gadgets are able to work as a result of them being able to receive a signal and they able to correctly interpret that signal and we in turn appreciate the devices. For the devices to correctly interpret these signals a kind of technique was used and this is known as Demodulation, this being that the devices are designed to receive this type of signals. The processes that led to being able to demodulate is what my focus is on; the process is known as modulation. Why modulation? This is due to the fact that not all intended users of a particular device or service reside close to the production station and also production signals called baseband signals cant travel much and would need a lot of power to transmit them over the air medium and this adds to the operating cost of the station and this is not acceptable. 2.0 Transmission medium for TV signal As with any kind of signal, the most important of that signal is to be received and decoded correctly, so that information encoded can be seen or viewed. The medium of passage of such signals is of consequence, because these helps to know the appropriate modulation to use and what, this information is tied to the channel coding, the advantages of the channel and the noise rate of that channel in consideration. For example, the transmission medium for sound received by the ears is usually air, sound can also travel through solids, liquids and plasma Electromagnetic waves have no need of any material substance for it to propagate but can be affected by the transmission media they pass through at the boundary between the media by absorption, reflection or refraction. Therefore, TV signals are like communicating data sent from one location to another which requires a pathway or medium. These pathways, called communication channels; two types of preferred media are: (a) Cable (twisted-pair wire, cable, and fibre-optic cable) and (b) broadcast (microwave, satellite, radio, and infrared). {Note:- Cable media use physical wires of cables to transmit data and information, while Twisted-pair wire and coaxial cables are made of copper, and fibre-optic cable is made of glass.} 2.1 BASEBAND SIGNAL The definition of a baseband signal is a signal that contains information, which may vary from audio signals, video signals, speech signal, image signal and many different other types depending on application and use. These signals cant move more than a few metres after production; for example, a speech signal; two persons can hear themselves clearly in close proximity to each other, as the distance between them increase, they start hearing faint messages or signals from each other and at a point, they cant hear each other again. Therefore for them to be heard no matter the distance between them there is need to modulate the speech signal generated by each person, so that each person can hear what the other person has said or is saying. A signal can be said to be an analogue data stream with which it varies with respect to space and time; with this property, each signal can be sampled, quantized, and transformed into digital data streams or packets. These processes it goes from being analogue to digital data streams or packet is called modulation. There are different modulation techniques used to carry different signals depending on the transmission medium and the condition inherent in that medium. 2.2 Modulation What is modulation? According to Margaret Rouse, modulation is the combination of signal to an electronic signal carrier, modulation is useful in direct current by turning it on and off to alternating current. Literally, modulation can be said to be a way of quicken the transfer of data or information through a medium. Transmission of sound through air has restricted degree of power generated by the lungs, to give the extent at which the voice can reach there is need to transmit it through a medium such as phone line, radio etc. therefore, the successful conversion of information in this case voice, to pass through a medium such as wire or radio waves is known as Modulation (www.complextoreal.com ). 2.3 TYPES OF MODULATION Modulation helps in many ways and it can be referred to as the process of transposing a signal wave onto a carrier wave in order to carry information. There are 3 three key properties of this carrier wave, which is a sinusoid wave with an amplitude, a phase and a frequency, these properties can be exploited to generate another kind of waveform to carry the intended information which is known referred to as a modulated signal. (www.encyclopediapro.com/mw/modulation) In most part of the world, frequency spectrum is expensive to waste and often its a national property, which means, to use it, the intending user has to be licensed and must follow a protocol process to have that frequency band assigned to him solely and given the channels parameters he can use. This is because, there are many different users competing for the same frequency band, due to the fact that the lower the frequency given, the lower the operating cost of using that frequency band. There are 2 broad class of modulation; they are the analogue modulation and the digital modulation. In analogue modulation, there is a continuous change in response to the signal to be modulated; this can be seen in Phase Modulation, Frequency Modulation, Amplitude Modulation, Single-Sideband Modulation, and Vestigial-sideband Modulation. In digital Modulation, there are changes in the signal position with respect to a starting position, while each position corresponds to a piece of information or symbol and can be represented on a constellation diagram. Examples include: Phase-Shift Key (PSK), Frequency-shift Key (FSK), Amplitude-shift Key (ASK), Minimum-shift Key (MSK), Gaussian minimum-shift Key (GMSK), Very minimum-shift Key (VMSK), Quadrature Amplitude Modulation (QAM), this a combination of PSK and ASK. Continuous phase modulation  (CPM) and Trellis coded modulation  (TCM). (www.encyclopediapro.com/mw/modulation) For each of these types of modulation techniques, their phases, frequencies and amplitude are assigned a unique sequence of bits which corresponds to an equal number of bits and make up a symbol that represent that particular phase or code. 3.0 QAM The modulation of interest for the purpose of his paper is the QAM, or Quadrature Amplitude Modulation, from research; it was noticed that QAM has both an analogue and digital modulation properties depending on how its to be applied. QAM is made up of two modulation scheme, namely the Amplitude-shift Keying which is achieved by modulating or changing the state of the amplitude of two carrier waves to carry two analogue message signal or two digital data streams. The other is the Phase-shift Keying, in which the sinusoidal waves are usually out of phase to each other and apart by 90o. When these two waveforms are combined, it results to Quadrature Amplitude Modulation (two different amplitudes two out of phase signals). QAM, this modulation technique is used to encode and transmit digital cable channels, while the simplest of the QAM techniques is the 16-QAM i.e. 24 phase points, this is able to carry 6MHz bandwidth regulated by the authoritys policy. The type of signal interested in is the signal generated from a video source, this type of signal consumes more than the set frequency of 6MHz, a typical video source signal is huge, so using 16- QAM techniques, it is possible to encode the signal onto the QAM carrier wave to carry it and pass through the 6MHz bandwidth limit and still be able to carry additional signals such as the voice signal component of the video signal. However there are different video formats such as the NTSC, PAL, MPEG; this video formats also help in reducing the size of video signal, hereby assisting the 16-QAM to effectively encode the signal without loss of quality and making it noise proof. Other variants of QAM includes 64, 256 phase variants, but as this phases size inc rease, so do they incorporate noise and mismatching often affect the performance of the receiver to be correctly tuned in to receive the sequence of bits sent over the medium. One of the uses of QAM is in the modulation of digital television systems, due to its high spectral efficiencies and the requirement of a cleaner path, and such hybrid fibre coaxial cables are used to deliver digital television signals to homes. (http://en.wikipedia.org/wiki/QAM_tuner, 2012) In the United Kingdom, 2 variants of the QAM are being used, this are the 16 and 64 variants and they are used for digital terrestrial TV like Freeview by British Telecoms Top-Up TV, while for the 256-QAM, is being considered for the HD version of freeview which is delivered over high speed fibre optics links to homes across the country. Therefore, the makeup of QAM is shown via the figure below and the different modulation techniques it uses to modulate and encode its own signal and how it lead to the development of QAM. 3.0.1 Amplitude Shift Keying (Ask) According to N.Vlajic (2010), Ask is the modulation of digital data with changes in the amplitude of a carrier while both frequencies an d phase remain constant; carrier signal is varied by representing the binary with 0 and 1. Also in ASK, the mode of operation is to vary the amplitude of the carrier wave to carry a baseband signal, while the frequency and phase remain constant. Ask has two levels called binary bits of implementing its modulation process and it is often referred to as Binary Amplitude shift keying or on-off keying (B-ASK or OOK). Each binary bit corresponds to a symbol that represents an amplitude level. According to (Glover and Grant, 2004, chapter 11, page 391), they said that in B-ASK, the two digital levels can be one and zero, to represent the pulse of a sinusoidal carrier wave, although any one of the changing amplitude can be inferred to be one and the other zero and from this result, it describes why it also referred to as on-off keying sequence. This method of digital sequence of one and zero can be referred to a switch and was used to transmit Morse codes (Wikipedia) in the early 20th century. In recent times, additional amplitude levels has been developed for enhanced encoding schemes such as a 4 four level encoding scheme to take on two bits or 22with corresponding shift in amplitude, also there is an eight level scheme to represent 3 three bits or 23, and so on. This gives a reduced power required to transmit and hence advantageous to use. (Wikipedia-http://en.wikipedia.org/wiki/Amplitude-shift_keying) A binary amplitude-shift keying (BASK) signal can be defined by S (t) = A m (t) cos 2pfct. For: (0 Implementation of ASK is relatively cheap and simple but its amplitude is usually affected by noise, distortion s and the propagation conditions on different route which makes the process more difficult. In ASK digital data is transmitted over an optical fiber. Figure 1. ASK signal representation. 3.0.2 Phase shift keying (PSK) Phase-shift keying (PSK) refers to a modulation scheme that is used to carry information by changing, or modulating, the phase of the carrier wave. PSK can still be defined as the modulation of digital data with amplitude at peak, frequency remain constant and phase with carrier signal varied to depict binary 0 or 1, with binary 0 = 180 degree phase and binary 1 = 0 degree.PSK is not sensitive to error and productively make use of bandwidth, so high data rate is possible but has more complex signal detection (N. Vlajic, 2010). This modulation scheme like the Amplitude shift Keying (or ASK) also uses a finite number of distinct signals to represent digital data. Each of the finite phases, is assigned a unique pattern of binary digits that forms a symbol. Phase shift keying comes in two forms, which are binary PSK (this uses two phases which are 180o apart) and Quadrature PSK (this uses four phases and the phases are 45o, -45o 135o and -135o). (Forouzan, 2013 pg 144) 3.0.2.1 Binary PSK In Binary PSK, it has only two signal element said suggested by Forouzan, 2013, pg 142; with each phase set at 0o and the other at 180o. The general form for BPSK follows this equation Sn (t). (wikipedia- H. Stern S. Mahmoud, Communications Systems, Pearson Prentice Hall, 2004, p283) s_n(t) = sqrt{frac{2E_b}{T_b}} cos(2 pi f_c t + pi(1-n )), n = 0,1. This yields two phases, 0 and à Ã¢â€š ¬. In the specific form, binary data is often conveyed with the following signals: s_0(t) = sqrt{frac{2E_b}{T_b}} cos(2 pi f_c t + pi ) = sqrt{frac{2E_b}{T_b}} cos(2 pi f_c t)For binary 0 s_1(t) = sqrt{frac{2E_b}{T_b}} cos(2 pi f_c t) For binary 1 [where fc is frequency of the carrier-wave.] Also, the BER of a two signal BPSK in AWGN can be calculated as follows P_b = Qleft(sqrt{frac{2E_b}{N_0}}right) P_b = frac{1}{2} operatorname{erfc} left( sqrt{frac{E_b}{N_0}}right) 3.0.2.2 Quadrature PSK This sub part of psk is such that it uses two separate BPSK modulations to generate a QPSK modulation scheme; this is able to work due to each BPSK band as an in-phase carrier and the other out of phase carrier. The phases are different and the first point is located at 45o, then 135o, then -135o and lastly -45o, the amplitude stays constant at 2 ½. The bit stream is then split into two bit streams I (in-phase) and Q (Quadrature) .The bit stream in-phase (I) is called the even stream and quadrature(Q) is called Odd stream. (http://turboblogsite.com/quadrature-phase-shift-keying-qpsk-modulation.html) QPSK is used mostly to transfer digital data by varying the phases of the carrier signal, the 4 phase points tally with 4 points on a circle and can be so represented. The figure below shows the mapping of the 4 phase points. QPSK diagram showing how four different binary codes can be transmitted Fig: QPSK diagram showing how four different binary codes can be transmitted The list below gives some of the other commonly used forms of phase shift keying, PSK, they are O-QPSK Offset Quadrature Phase Shift Keying, 8 PSK 8 Point Phase Shift Keying, 16 PSK 16 Point Phase Shift Keying, QAM Quadrature Amplitude Modulation, 16 QAM 16 Point Quadrature Amplitude Modulation and 64 QAM 64 Point Quadrature Amplitude Modulation (http://www.radio-electronics.com/info/rf-technology-design/pm-phase-modulation/what-is-psk-phase-shift-keying-tutorial.php) Figure 2. PSK signal diagram representation 3.1 QAM bits per symbol The advantage of using QAM is that it is a higher order form of modulation and as a result it is able to carry more bits of information per symbol. By selecting a higher order format of QAM, the data rate of a link can be increased. (http://www.radio-electronics.com/info/rf-technology-design/pm-phase-modulation/8qam-16qam-32qam-64qam-128qam-256qam.php) The table below gives a summary of the bit rates of different forms of QAM and PSK. Modulation Bits per symbol Symbol Rate BPSK 1 1 x bit rate QPSK 2 1/2 bit rate 8PSK 3 1/3 bit rate 16QAM 4 1/4 bit rate 32QAM 5 1/5 bit rate 64QAM 6 1/6 bit rate 3.1.1 Quantized QAM using constellation diagram In QAM, the constellation diagram plots are usually arranged in square formation with different spacing and this spacing point represent binary bits per symbol, this spacing point is in the power of 2s. The more the bits per symbol, the more it is to transfer more information over a given channel or medium. But as the bits increase, the points move closer and make the system susceptible to noise corruption, and this gives rise to a high BER ratio, making useless the information sent due to its high noise component. There are different bit positions for the constellation diagram, this diagrams show the different position of each symbol and the states of QAM, and the constellation diagrams for BSPK, 16 QAM. 32 QAM, 64 QAM. Therefore, the figures below show various constellation diagrams: http://www.radio-electronics.com/info/rf-technology-design/pm-phase-modulation/modulation-constellation-bpsk.gif http://www.radio-electronics.com/info/rf-technology-design/pm-phase-modulation/modulation-constellation-16qam.gif http://www.radio-electronics.com/info/rf-technology-design/pm-phase-modulation/modulation-constellation-32qam.gif http://www.radio-electronics.com/info/rf-technology-design/pm-phase-modulation/modulation-constellation-64qam.gif 3.1.2 QAM applications QAM is in many radio communications and data delivery applications. However some specific variants of QAM are used in some specific applications and standards. For domestic broadcast applications for example, 64 QAM and 256 QAM are often used in digital cable television and cable modem applications. In the UK, 16 QAM and 64 QAM are currently used for digital terrestrial television using DVB Digital Video Broadcasting. In the US, 64 QAM and 256 QAM are the mandated modulation schemes for digital cable as standardised by the SCTE in the standard ANSI/SCTE 07 2000. In addition to this, variants of QAM are also used for many wireless and cellular technology applications. 4.0 Conclusion In this review, it is clearly shown that Amplitude Shift Keying (ASK) and Phase Shift Keying (PSK) modulation techniques that form Quadrature Amplitude Modulation (QAM) ensures effective transfer of TV signals In QAM different combination of amplitude and phase are used to achieve higher digital data rate, the number of bit transmitted per time T (sec) interval can be further increased by increasing the number of levels used References Behrouz A.

karma :: essays research papers

Christians and Americans different from Japanese. But here too the core experiences were the same. There are obviously two sides of the story. One must look at both sides with careful eye and determine for they what they believe is true. This is where the idea of reincarnation comes in. Because it is 7 incorporated in so many religions, you find an answer to a question, which you truly want to know the answer to, and do not abandon your faith in doing so. Reincarnation is detected in many religions. Reincarnation is normally thought of as a Hindu philosophy and it is traced back to Hinduism, yet it can be found in Judaism, Christianity, and Buddhism and in many more religions. In Judaism, reincarnation is known as Gilgul. Though it has a different name it has almost the exact same meaning. Gilgul was a dominant teaching in Judaism for over three hundred years. Cabala, a book of Judaism, which is often, studied by Rabbi’s, one of the holy books of the Jews which talks of reincarnation. Rabbi Steinsaltz (Cranston 181) is an authority on the Cabala. He states: According to Cabalistic doctrine, the Torah contains not only manifest but also hidden truths: the same transcendent God whom the Bible celebrates as supreme king and lawgiver is, from the mystical also an infinity of divine knight that exists as the foundation of every human beings soul. For me, every soul is an emanation or spark of the divine, and its ultimate purpose is to rejoin the God it came from.... I hope to demonstrate the secrets of the Cabbala-, which rationalistic Rabbi’s of the nineteenth century dismissed as dangerous magic-, are fully consonant with traditional Rabbinic Judaism. (181) 7 this view is also held by a large group of Orthodox Jews known as the Hasidim. Reincarnation is universally taught among them. On the other hand, the soul, its life and immortality are rarely mentioned in the Old Testament. There is also no direct denial of it either. In the Book of Job (14:14), Job plainly asks, â€Å" If a man dies will he live again?† but receives no answer. So in the Old Testament, reincarnation is not ruled out it is just not brought up as a major point in the book. On the other hand, if one were to look into the Bible, the question of like after death is brought up and answered.

Robotization of Human Workforce

The Robotization of a Human Workforce Job satisfaction has been defined as â€Å"a pleasurable emotional state resulting from the appraisal of one’s job or job experiences. † It lists two different formulas for calculating job satisfaction: the Value Percept Theory, and the Job Characteristics Theory. This paper discusses the former and how it relates to Foxconn and its CEO, Terry Guo, whom writers Balfour and Culpan describe as a â€Å"ruthless taskmaster. † The Value Percept Theory is essentially the workers’ WIIFM (What’s In It For Me) paradigm, describing how certain job elements affect employee satisfaction, and the ramifications of that satisfaction. It focuses on eight specific categories of employee values: how the salary compares to other employees in the same line of work; the frequency with which qualified people are promoted; supervisors’ conduct and recognition of employee efforts; the enjoyability and qualifications of co-workers; The â€Å"psychological pay† derived from the work itself, described by the text on page 106 as including â€Å"utilization of ability, freedom and independence, intellectual stimulation, creative expression, (and) sense of achievement†; to what extent the work has a positive impact on society; the level of prestige associated with the job; and the safety and comfort afforded on the job. Most people base their job satisfaction on five of those eight criteria. The magazine article discusses Chairman Gou’s business philosophy and response to twelve employee suicides during the first few months of last year. According to the authors, Gou realized there was a problem after the ninth employee jumped to his death from one of the company’s ubiquitous, crowded dormitories. Gou responded by stringing netting around the exterior of the dormitories at second-floor level and set up a 24-hour employee hotline. He also gave employees a 30% pay raise and promised another salary bump during 2011 – principally due to pressure by one of his biggest customers, Apple. These measures were almost certain to reduce the number of employees who sought their own demise by jumping from their dormitory windows – provided they did not land on one of the steel support braces – but it failed to address the real problem of why so many people became despondent enough to end their own lives.
