Pure Mafia - a novel about child labour, plus thesis and commentary
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This PhD in Creative Writing consists of three parts. The first part is a full-length novel, approximately 80K words, entitled Pure
Mafia. It is a drama about child labour and the Pakistani “carpet mafia”. This is
intertwined with the story of an unhappily married man undergoing a midlife crisis who
has an affair with a younger woman; the latter is instrumental to the main plot about
child labour. The book’s second main theme is British Pakistanis. An overarching theme
is abuse and exploitation, both personal and global, but ultimately of redemption and
renewal. The story is set in 2010/2011, mainly in London, England, with a middle
section in Lahore, Pakistan. The second part is an academic thesis, approximately 20K words, entitled Cheap Labour = Child Labour, on the main theme of the novel, child labour. It attempts to show that child labour is an inevitable consequence of cheap labour generally, and that the only way to tackle child labour is to address cheap labour. The thesis has been consciously and deliberately written as an objective, third person, standalone document and for this reason does not mention the novel. It is partly designed to fulfil the general
PhD criterion of demonstrating scholarship and research. The third part is a subjective, first person critical commentary, approximately 15K words, on the writing of the novel and the thesis, the connection between them, and the research context; it is entitled Pure Mafia: A critical commentary. It explains why
the main thesis is on child labour, rather than on the creative process or an English
Literature thesis; however, the commentary does include in some detail an insight into
the creative process, as well as a discussion of influences and tradition of writing. The final section of the commentary summarises this entire PhD’s original
contribution to knowledge

No full textFree-Running Ring Oscillators for Crystal-Free Communication Systems: Design, Simulation Challenges, and Frequency Stability Improvements
No full textThis thesis presents techniques for enhancing the frequency stability of ring oscillators (ROs) for crystal-free wireless communication systems. The first major contribution is a tutorial-style study of frequency stability metrics, providing clear definitions, conversions methods, and comparative analysis of commonly used figures of merit such as phase noise, Allan deviation, and jitter. The second contribution addresses the challenges of simulating phase noise in free-running ROs. Key techniques including Periodic Steady-State Noise (PNoise), Harmonic Balance Noise (HBNoise), and transient noise analysis are evaluated in terms of accuracy, convergence behavior, and simulation runtime. Based on these results, practical guidelines are offered for effective simulation of oscillator phase noise. This work lays the groundwork for the design efforts pursued in this thesis and the author\u27s ongoing Ph.D. research.
The core design contribution is a Digitally Controlled Ring Oscillator (DCRO) that employs current-starved inverter delay cells with binary-weighted transistor DACs. These DACs enable real-time adjustment of effective transistor widths via digital control words, allowing dynamic symmetry tuning of individual delay stages to mitigate flicker noise upconversion without requiring a large number of analog I/Os. A prototype oscillator, as well as an RF front-end for its testing, has been submitted for fabrication in Intel\u27s 16 nm FinFET process, with silicon return expected in Q4 2025. Looking ahead, two system-level control strategies are proposed to maintain both short-term phase noise performance and long-term frequency stability without a crystal reference. The first uses a charge-pump-based feedback loop driven by the received RF signal but is limited by poor channel selectivity. The second is a dual-mode architecture comprising: (1) a calibration mode using an external PLL to sweep across temperature and voltage corners, generating a multi-dimensional lookup table (LUT) of control words, and (2) a free-running mode where the PLL is disabled, and the DCRO is stabilized using on-chip LUT-based control. Together, the proposed DCRO architecture and control strategies aim to enable a digitally tunable, low-power, inductor-free solution for next-generation crystal-free wireless communication systems

Role of Ultrasound for the Diagnosis of Uterine Prolapse in Women: A Systemic Review
No full textBackground: Uterine prolapse is the herniation of the uterus into or beyond the vagina as a result of failure of the ligamentous and fascia supports. It often coexists with prolapse of the vaginal walls, involving the bladder or rectum.Objective: The aim of this study is to evaluate the role of ultrasound for the diagnosis of uterine prolapse in young women. Methodology: In this systematic review data extracted by Medline, PubMed, science direct and Obs-gyne online library that were queried for studies published between 2000 to 2021 by using specific MeSH terms. In this systematic article we reviewed 10 retrospective style analytical studies for the collection of data. Results: 10 studies conducted between the years 2000 to 2021 were included in this systematic review. The total sample size was 2500 women aged between 10-60 years. All subjects were examined by trans-perineal three-dimensional ultrasound for the detection of uterine prolapse. Out of 2500 patient almost 1000 determine with uterine prolapse on ultrasound. Ultrasound findings had excellent predictive value for the diagnosis of clinical uterine prolapse. An eye‐ shaped vaginal canal with an antero-posterior diameter of greater than 10 mm in the rendered axial plane was a sign of uterine prolapse. This sign may be helpful for detecting concealed uterine prolapse in complex pelvic organ prolapse. In fact, uterine prolapse can often be more prominent on imaging than on clinical examination. This may be due to the fact that the functional anatomy of the levator hiatus seems to matter most for uterine descent.Conclusion: From this systematic reviewed study we concluded that Ultrasound is the most appropriate form of imaging in uro-gynecology for reasons of low cost, access and performance, and due to the fact that it provides information in real time. Trans-perineal three-dimensional 2 ultrasound can evaluate the morphological changes of levator hiatus in patients with uterine prolapse, and the area of levator hiatus has high diagnostic value for uterine prolapse.

DIFFERENTIAL CODE SHIFTED REFERENCE IMPULSE-BASED COOPERATIVE UWB COMMUNICATION SYSTEM
No full textCooperative Impulse Response – Ultra Wideband (IR-UWB) communication is a radio technology very popular for short range communication systems as it enables single-antenna mobiles in a multi-user environment to share their antennas by creating virtual MIMO to achieve transmit diversity. In order to improve the cooperative IR-UWB system performance, we are going to use Differential Code Shifted Reference (DCSR). The simulations are used to compute Bit Error Rate (BER) of DCSR in cooperative IR-UWB system using different numbers of Decode and Forward relays while changing the distance between the source node and destination nodes. The results suggest that when compared to Code Shifted Reference (CSR) cooperative IR-UWB communication system; the DCSR cooperative IR-UWB communication system performs better in terms of BER, power efficiency and channel capacity. The simulations are performed for both non-line of sight (N-LOS) and line of sight (LOS) conditions and the results confirm that system has better performance under LOS channel environment. The simulation results also show that performance improves as we increase the number of relay nodes to a sufficiently large number.+923214674079 , +92323415504
Sapphire stories: the symbolic representation of blue motifs in Islamic architecture of Pakistan
No full textThis article focuses on analyzing and exploring the implication of blue motifs in terms of the representation of Islamic architecture in Pakistan. Architecture holds a great deal of importance within every nation\u27s social and cultural domains. In the same way, architecture has played a significant role in dispensing Islam as a religion. The manifestation and reflection of blue motifs are present in various forms, such as formal, structural, and spatial. Moreover, these shapes carry symbolic connotations when presented in the form of ornamentation, geometrical patterns, floral displays, and arabesque. Furthermore, this study provides a valuable contribution to enhancing the awareness of the significance and representation of blue motifs in the Islamic architecture of Pakistan for the research. Secondary and primary data were collected to achieve the objectives of the study. The study concludes that mosques and shrines in Pakistan are loaded with examples in which the representation of blue motifs within the domain of Islamic architecture is quite evident
