    This paper constructs the compact, detailed and extended models, and focuses on the algebraic theoretic strings and language of each transition of the finite automata scheme. It was discovered that from the initial stage to the final stage of cement production processes, each transition or production process can have a particular language. In addition, a language scheme is developed for each of the sub-states (sub-model) that leads to a theoretic study of language scheme and semantics of the model. It can be deduced that when represented as binary codes, the established schemes in the sub-states can be studied as a Boolean algebraic scheme.&nbsp

    The Stretch-Engine: A Method for Creating Exaggeration in Animation Through Squash and Stretch

    Get PDF
    Animators exaggerate character motion to emphasize personality and actions. Exaggeration is expressed by pushing a character’s pose, changing the action’s timing, or by changing a character’s form. This last method, referred to as squash and stretch, creates the most noticeable change in exaggeration. However, without practice, squash and stretch can adversely affect the animation. This work introduces a method to create exaggeration in motion by focusing solely on squash and stretch to control changes in a character’s form. It does this by displaying a limbs' path of motion and altering the shape of that path to create a change in the limb’s form. This paper provides information on tools that exist to create animation and exaggeration, then discusses the functionality and effectiveness of these tools and how they influenced the design of the Stretch-Engine. The Stretch-Engine is a prototype tool developed to demonstrate this approach and is designed to be integrated into an existing animation software, Maya. The Stretch-Engine contains a bipedal-humanoid rig with controls necessary for animation and the ability to squash and stretch. It can be accessed through a user interface that allows the animator to control squash and stretch by changing the shape of generated paths of motion. This method is then evaluated by comparing animations of realistic motion to versions created with the Stretch-Engine. These stretched versions displayed exaggerated results for their realistic counterparts, creating similar effects to Looney Tunes animation. This method fits within the animator’s workflow and helps new artists visualize and control squash and stretch to create exaggeration

    Beware the Fury of the Digital Age Consumer: Online Consumer Revenge: A Cognitive Appraisal Perspective

    Get PDF
    Online consumer revenge is costing companies millions of dollars annually. Yet, a limited number of studies have investigated the factors that influence online consumer revenge and the degree to which they carry on across cultural boundaries. A serious gap was noticed concerning the forms, triggers, and process of consumer revenge in the online context. Additionally, it was noticed that previous theoretical models of consumer revenge go directly from the desire for revenge state to the actual revenge state without explaining the cognitive process the consumer goes through when evaluating the decision whether or not to commit revenge. To address these research gaps, a mixed method approach was applied. A qualitative approach was employed first to explore this behaviour. Afterwards, a scenario based survey was used in order to examine and test the casual relationships between the variables identified in the first study on a larger sample from Jordan and Britain. Overall, the findings of this thesis have proven for the first time the secondary appraisal state consumers go through when evaluating their online revenge coping options. In this state, consumers were found to evaluate the reach of their actions, the risk involved, and the ability to perform the online revenge behaviour. Additionally, this thesis found that the British participants cognitively evaluate their online revenge options more extensively when compared to the Jordanian participants. The findings of this thesis also identify a new set of triggers for online consumer revenge including the type (process/outcome) and the severity of the service failure. This finding shifts away from the traditional fairness violations view of the triggers of consumer revenge. Moreover, the findings of this thesis establishes the role of the national culture in influencing online revenge as demonstrated by the difference in the harm appraisals, negative emotions, and the desires for revenge between the English and Jordanian participants

    This study aimed to validate factors related to organizational commitment among teachers in vocational colleges in Malaysia. As we know, the commitment given to the organization will make the organization manageable. However, there are issues regarding the commitment given by the teachers in vocational colleges, which has led to poor performance of college organizations. Some studies have found that factors such as narrative commitment, affective commitment and ongoing commitment cause the overall commitment to the organization to be disrupted. In this study, a fully quantitative approach is used to determine factors in the organization commitment of vocational college teachers. The questionnaire was administered to 264 vocational college teachers in three states in Malaysia namely Negeri Sembilan, Melaka and Johor. The data obtained were then analyzed using Structural Equation Modeling (SEM) using AMOS 21 application. Confirmatory Factor Analysis was performed to obtain factor loading for each element obtained namely narrative commitment, affective commitment and continuous commitment. The analysis results show that the factors reflect the appropriate fit and meet all the criteria for validation. Therefore, the findings of this study can further confirm previous findings on this issue

    Stages of development in Arabic philosophical nomenclature: emergence, progression and stability

    Get PDF
    The study of the creation of a technical language within an existing natural language reveals to us both the internal and external dynamics of this complex phenomenon. The history of Arabic lexical definitions of different disciplines in the historical Islamic civilization provides us with a wealth of information on how these processes take place at each level of development. In this article while we will be highlighting on the history of Arabic intellectual lexical definitions we will focus on the development of the disciplines that constitute the Arabic philosophical technical languages i.e. Kalām and falsafah. In each discipline we closely followed the three conventional phases of development i.e. emergence, progression and stability. It should be remarked that though there are distinctive features of each phase, yet there are equally overlaps among these phases. This study brought to our attention the significant place of al-Ta rifat of al-Jurjānī as the most sophisticated dictionary of sciences in the historical Islamic civilization

    Public key exponent attacks on multi-prime power modulus using continued fraction expansion method

    Get PDF
    This paper proposes three public key exponent attacks of breaking the security of the prime power modulus =22 where and are distinct prime numbers of the same bit size. The first approach shows that the RSA prime power modulus =22 for q<<2q using key equation −()=1 where ()= 22(−1)(−1) can be broken by recovering the secret keys  / from the convergents of the continued fraction expansion of e/−23/4 +1/2 . The paper also reports the second and third approaches of factoring multi-prime power moduli =2 2 simultaneously through exploiting generalized system of equations −()=1 and −()=1 respectively. This can be achieved in polynomial time through utilizing Lenstra Lenstra Lovasz (LLL) algorithm and simultaneous Diophantine approximations method for =1,2,…,

    Antibacterial resistant bacteria cause a big concern to poultry and to public health in general because some bacterial poultry pathogens can infect human or transfer their resistance ability to human pathogens. Non therapeutic use of antibacterial in poultry especially as growth promoters to increase feed conversion efficiency is thought to be one of the main causes of resistance. The study included pulmonary swab samples collected during necropsy from 120 poultry farms showing respiratory symptoms with mortality. The disc diffusion method for antibiotic sensitivity testing was performed and antibiotic disks for 21 antibiotics was used. The results showed that three antibacterials were sensitive to more than 50% of the isolates. The first is doxycycline and 69.9% of the isolates were sensitive. The second is Cefalexin with 60.5% sensitive isolates and third is Chloramphenicol with 55.2% sensitive isolates. In the rest of antibacterials, less than 50% were sensitive. Five isolates were found resistant to all antibacterials. Moreover, three samples were found negative with no bacterial growth. The present study concluded that 50% of the aerobic bacteria isolated from poultry lungs are resistant to 85% of the 21 antibiotics tested in the study

    The relativistic R-matrix method is used to calculate elastic and inelestic cross sections for electrons incident on caesium atoms with energies from 0 to 3 eV. In addition to the total cross sections, results are presented on the differential cross section, σ, and the spin polarization, Py, of the scattered electrons as a function of energy at eight scattering angles (10°, 30°, 50°, 70°, 90°, 110°, 130°, 150°). Also the differential cross section, spin polarization and the left-right asymmetry function, As, are calculated as a function of the scattering angles at a number of chosen values of energies. The calculation reveals a wealth of resonances around 2p1/2 and 2p3/2 thresholds. The resonances are analysed in detail and their role in the scattering process is discussed. The density matrix formalism is used to derive expressions for the Stokes' Parameters to describe the state of the photons emitted in electron-atom collision experiment. Numerical results for the Stokes Parameters of the light emitted in the decay 6p 2p1/2,3/2 -> 6s 2S1/2 in atomic caesium after electron impact excitation are presented and compared with the available measurements. These results show what effects can be expected and may be useful for the planning of future experiments. The angular distribution and the integrated cross sections have been calculated at incident electron energies 20, 25 and 30 eV, in e-N2 scattering. The calculations are based on the use of numerical basis functions in the R-Matrix method, and exchange and polarization effects are included. Also variation of the mixing parameter, between p- and f- partial waves and the individual eigenphases with the internuclear distance are presented. The mixing parameter has shown to be a rapidly varying function of the internuclear distance contradicting the assumption made by Chang (1977)

    ABSTRACT: The current study aims to assess groundwater quality for drinking and various domestic uses for selected wells from the district of Tal Abta and some of its affiliated villages located southwest of Mosul, Iraq. As samples were collected from ten wells distributed randomly in the study area, starting from summer until winter, with ten replicates for each well, physical, chemical and bacterial tests were conducted: temperature, electrical and chemical conductivity such as pH, total alkaline T. alkali, total hardness T. Hardness, phosphate ions PO4-3, sodium Na+, chloride, Cl-, sulfate SO4-2, nitrate NO3- and the total number of bacteria TPC, with the application of the sub-index model to evaluate the quality of water for drinking and civil use. The results of the Water Quality Index (WQI) indicated a deterioration in the quality of the studied groundwater, as the values ranged between (73.5 to 1538), so all studied samples are considered (Very Poor to Unfit quality) for drinking and civil uses; this deterioration is due to the high levels of Electrical conductivity, total hardness and sulfate ions, which amounted to (5994) uS cm-1 and (6420-2130) mg L-1, respectively, with a high total number of bacteria (TPC), which reached (1611) cells mL-1. Keywords: drinking water quality; water quality index; Tal-Abtah district; Mosul city – Iraq.   Modelo de subíndice para avaliar a qualidade da água de lençol freático para consumo e uso civil   RESUMO: O presente estudo visa avaliar a qualidade da água subterrânea para consumo humano na forma de bebida e vários usos domésticos, provenientes de poços selecionados do distrito de Tal Abta e algumas de suas aldeias afiliadas localizadas a sudoeste da cidade de Mosul, Iraque. Foram coletadas amostras de dez poços distribuídos aleatoriamente na área de estudo, no verão e no inverno, com dez repetições para cada poço. Foram realizados testes físicos, químicos e bacterianos, com base nas seguintes variáveis: temperatura, condutividade elétrica e química como pH, T alcalino total. álcali, dureza total T, Dureza, íons fosfato PO4-3, sódio Na+, cloreto, Cl-, sulfato SO4-2, nitrato NO3- e o número total de bactérias TPC; posteriormente aplicou-se um modelo de sub-índice para avaliar a qualidade da água para beber e uso civil. Os resultados do índice de qualidade da água (IQA) indicaram uma deterioração da qualidade das águas subterrâneas estudadas, pois os valores variaram de 73,5 a 1538, portanto todas as amostras estudadas são consideradas com qualidade “muito ruim” a “inadequadas” para consumo humano e uso civil. Essa deterioração se deve aos altos níveis de condutividade elétrica, dureza total e íons sulfato, que totalizaram 5994 uS cm-1 e 6420-2130 mg L-1, respectivamente, com elevado número total de bactérias (TPC), que atingiu 1611 células mL-1.
