Identifying idiolect in forensic authorship attribution: an n-gram textbite approach
No full textForensic authorship attribution is concerned with identifying authors of disputed or anonymous documents, which are potentially evidential in legal cases, through the analysis of linguistic clues left behind by writers. The forensic linguist “approaches this problem of questioned authorship from the theoretical position that every native speaker has their own distinct and individual version of the language [. . . ], their own idiolect” (Coulthard, 2004: 31). However, given the diXculty in empirically substantiating a theory of idiolect, there is growing concern in the Veld that it remains too abstract to be of practical use (Kredens, 2002; Grant, 2010; Turell, 2010). Stylistic, corpus, and computational approaches to text, however, are able to identify repeated collocational patterns, or n-grams, two to six word chunks of language, similar to the popular notion of soundbites: small segments of no more than a few seconds of speech that journalists are able to recognise as having news value and which characterise the important moments of talk. The soundbite oUers an intriguing parallel for authorship attribution studies, with the following question arising: looking at any set of texts by any author, is it possible to identify ‘n-gram textbites’, small textual segments that characterise that author’s writing, providing DNA-like chunks of identifying material
Formations of Antidoxy: Michael Muhammad Knight, Progressive Muslims, and the Islam of the Self
No full textMichael Muhammad Knight is known primarily as a provocative author concerned with the North American Islamic community. Knight gained attention with his 2004 novel, The Taqwacores, in which he detailed the lives of Islamic punk rockers, the eponymous taqwacores, as they navigated issues pertaining to religion, punk rock, youth, and life in Western modernity. Much of Knight's other writing is concerned with his own life, religion, and religious struggles, all of which are likewise represented in his fiction as well. Implicit throughout the totality of Knight's body of work is his desire to change the Islamic tradition so that it is able to better benefit individual practitioners. In a noteworthy 2003 essay, Knight argued that we should "forget what is and is not Islam," suggesting that it should be up to individual practitioners to determine what Islam is and is not. In this thesis, I argue that this statement is part of a larger program of reform, advanced by Knight and a group of progressive Muslims in the academy, that takes as its goal, the remaking of the Islamic tradition such that individual religious practitioners cannot be held responsible for any adherence to notions of orthodoxy and orthopraxy outside of their own personal preferences. Knight's reformation ideas would put an end to the meaningful use of authoritative models apart from the selves of individual Muslims. Thus, Islam would be completely divested of meaningful authority, and would become an Islam of the Self, founded on what I have termed an antidoxy. I argue this through close readings and discursive analyses of Knight's body of work, and through careful examination of the relationships between Knight, the progressive Muslims movement, and their approaches to understanding Islam as a part of the multicultural milieu of secular Western societies. I also provide a detailed analysis of the similarities and intersections between Knight's work and the literature of the progressive Muslims, and I consider the relationships between punk rock, authority, and freedom. I further supplement my argument with insights culled from the work of Talal Asad, and investigations into the construction of Arabic verbs

Logistics in Yemen: Identifying Demerits on Lack of Railways in Yemen
No full textIf one asks today whether Yemen can be extended by railway lines, it is natural to answer that the geographical nature of Yemen does not allow the extension of the railway line. It is surprising that the Ottoman Empire decided more than 100 years ago to complete this project, but the fall of the empire deprived Yemenis of this Great achievement. Under the title of establishing a modern network of railways for metals, goods and passengers, in recent years, practical steps have been taken to establish a railway network in Yemen and linking it to an international network of economic feasibility studies, but the railway project in Yemen is still just studies prepared by several companies. In 2013 there were talks between the Yemeni government and Russia, the outcome of the Yemeni-Russian talks committee was for the planning of the establishment of a local company in Yemen specializing in railways Under the supervision of the Russian leadership, a project that is the first of its kind as it aims to build an infrastructure. In this research paper the author attempt to use quantitative and qualitative research method, plan and execute fieldwork, collecting data from Competent ministerial bodies, ministry of transportation, Visit the specified area of the project) mineral wealth areas, coastal areas) etc. in Yemen, during fieldwork. Compile preliminary maps of the first alternative - Shahn / Aden and the second alternative - Muscat / Salalah / Sarfeet / Algheiza / Aden. During fieldwork and data collection, the author will visit ministry of transportation to meet the representative to get the requested data of the Proposed railway project along with Yemen land transportation affairs authority, then the author will visit designated area of the proposed project to meet the local authorities of each area to collect the data and discussing the main causes of the project's failure and delay along with that inspecting the security and services of the project’s designated area, although the government has conducted several studies on this project. After that the author will visit a the Minister of Transportation or a senior figure from the ministry for an interview to discuss the main challenges and constraints that causes the failure of the project and the delay to support the study, finally the author will visit Ministry of Public works and roads to collect preliminary maps of the International Coastal Railway (from Haradh to Shahn) and the economic feasibility study of the railway linking the mineral wealth areas (Al-Jouf and Marib Shabwa Balahaf). After analysing data and identifying findings that led to the projects failure, the author found three main challenges at present to build the railway project in Yemen are the absence of government economy, security and political stability

Pjezoelektrinės kompozicinės medžiagos, naudojamos mikrorezonatoriuose, kūrimas.
No full textThe presence of microresonators are more evident these days ranging from biometric sensors to gyroscopes. The application of sensors into the molding cavities is a new challenge that is yet to be studied more. On the other hand microresonators designed using piezo materials are showing some promising results. In this study the author aim to develop a microresonator with piezoelectric materials for quality control in injection molding. This aim is achieved by investigating PZT composite material by experimental testing. A finite element of the proposed microresonator is created and simulated using the comsol multiphysics software. From the experiment results, the young’s modulus is calculated and used in further simulation work to find the excitation frequencies of the new PZT material. In this research them microresonators are integrated with piezo materials. Piezo materials can generate electrical signals which can be used to measure natural micro level changes, where devices like vibrometers or some other measurement methods are destructive and which are really hard to be used. Moreover these materials could assure high functionality and accuracy for micromechanical systems
Static and Rotordynamic Analysis of a Plain Annular (Liquid) Seal in the Laminar Regime with a Swirl Brake for Three Clearances
No full textThe author conducts tests using a smooth annular seal with a radius of 101.6 mm (4.00 in) with three radial clearances (0.127, 0.254 and 0.381 mm) referred as 1X, 2X and 3X respectively, producing the radial clearance to radius ratios (Cvr/R) of 0.0025,0.005 and 0.0075. The seals have axial length of 45.72 mm (1.80 in), producing the length to diameter ratio of 0.45. ISO VG 46 oil is used as the testing fluid at a temperature range of 46.0-49.0 degrees Celsius to keep fluid flow laminar. A high pre-swirl insert is used to induce high fluid swirl to the swirl brakes (SBs). Each SB comprises of 36 square cuts with an axial depth of 5.08 mm (0.2 in), radial height of 6.35 mm (0.25 in) and circumferential width of 6.35 mm (0.25 in). The author conducts static and dynamic measurements at = 2, 4, 6, 8 krpm, = 2.07, 4.14, 6.21, 8.27 bar (30, 60, 90, 120 psi), and eccentricity ratios, = 0.00, 0.27, 0.53, and 0.80. Static measurements include leakage rate, pre-swirl ratio and outlet swirl ratio, and the static load required to produce the eccentricity ratios.
Dynamic measurements comprise rotor-stator relative displacements, stator acceleration, and applied dynamic load. The measurements are used to calculate stiffness, damping, virtual mass and effective damping coefficients for the seals.
Most importantly, SBs are shown to be effective in minimizing inlet fluid rotation at the 3X clearance but ineffective at the 1X and 2X clearance. When SBs are used with the 3X clearance seal, the cross-coupled stiffness variables have the same sign meaning that the seal would have a WFR of zero and would not produce destabilizing forces on a pump rotor. However, at the 3X clearance, the smooth annular seal has a negative direct stiffness K that could eventually “suck” the rotor into contact with the stator wall, along with dropping the natural frequency of the pump rotor, further reducing its dynamic stability.
Dynamic measurements are compared to predictions based on a model developed by Zirkelback and San Andrés [16]. Most of the predictions agree well with the test data. Notable exceptions are the direct and cross-coupled stiffness coefficients for the 3X clearance. Predictions showed positive direct stiffness and opposite signs for the cross-coupled stiffness coefficients; whereas, the data showed negative direct stiffness and the same positive sign for the cross-coupled stiffness coefficients. Also, for the 1X clearance seal, measured direct damping was higher than predicted at w > 2krpm by about 25%. For the 1X clearance seal, measured cross-coupled damping was lower than predicted by approximately 2-5 times.
At most of the test conditions, measured direct virtual mass coefficients are about 6 times greater than predicted but follow the same general trend. For the 1X and 3X clearance seals, predictions are lower than measured data while predictions match test data well for the 2X clearance seals.
The model predicts the whirl frequency ratio WFR very well for the 1X and 2X clearance seals at all test conditions but fails to predict zero WFR for the 3X clearance se
The synthesis of alkylated or acylated nitroarene cyclopentadienylironcomplexes:
No full textTime-dependent oxidation of η6-alkylaniline-η5-cyclopentadienyliron hexafluorophosphates, 17–32, allows for the preparation of nitrobenzene complexes with alkyl 33–48 or keto 49 substituents. Alkylnitroarene complexes are prepared by the oxidation of their corresponding aniline complexes with H2O2 in CF3CO2H for 20 min. An increase in the reaction time to 24 h gives rise to nitroarene complexes with keto substituents in lower yields. The use of nitroarenes as starting materials in the synthesis of alkanoates is of importance since it allows for the preparation of a large number of this class of compounds with a variety of alkyl substituents. Two different approaches have been utilized to allow for the synthesis of alkanoates. The first approach involves nucleophilic aromatic substitution of alkylnitrobenzene complexes with ethyl alkylacetoacetates followed by demetallation to give the alkanoates. This methodology allows for the preparation of these esters with a variety of alkyl substituents in either the meta or para positions. Another route outlines the reaction of phenylsulfonylacetonitrile with nitroarene complexes to prepare alkanoic acid precursors with alkyl substituents in the ortho, meta and para positions. The preparation of a larger pool of nitroarene complexes clearly demonstrates the advantage of using the cyclopentadienyliron arene complexes in the synthesis of alkanoates or their precursors, arylated phenylsulfonylacetonitriles, over traditional synthetic routes
Postoperative Outcomes of Low Pressure versus Standard Pressure Pneumoperitoneum in Laparoscopic Cholecystectomy
No full textObjective: To compare outcomes in laparoscopic cholecystectomy performed with either low-pressure pneumoperitoneum (LPP <12 mm Hg) or standard-pressure pneumoperitoneum (SPP >12 mm Hg).
Methodology: This randomized trial was conducted over six months, from September 2020 to March 2021, with data prospectively collected from patients. Patients aged 20-60 years with symptomatic gallstones were divided between Group A or Group B randomly, with 31 patients in each group. Group A underwent surgery with low-pressure pneumoperitoneum (LPP), whereas Group B underwent surgery with standard-pressure pneumoperitoneum (SPP). Postoperative ileus was assessed at six hours, while shoulder tip pain was evaluated at 24 hours post-surgery, and comparisons were made between both groups.
Results: There were 16 males and 15 females in group A and 14 males and 17 females in group B. Mean age in Group A was 40.35±7.27 years and in Group B 42.28±6.95 years. Group A had an average hospital stay of 1.06 ± 0.21 days and Group B had 1.09 ± 0.37 days. 10 patients (32.3%) experienced right shoulder tip pain in the LPP group as compared to 19 patients (61.3%) in the SPP group (p=0.021). Paralytic ileus was noticed in 6 patients (19.4%) in Group A and 16 patients (51.6%) in Group B (p<0.007).
Conclusion: LLP is a possible and safe option that significantly reduces postoperative shoulder tip pain and paralytic ileus, facilitating earlier bowel recovery compared to standard-pressure pneumoperitoneum
