Design and Development of Hybrid Maximum Power Point Tracking Algorithm for Photovoltaic Cell
Photovoltaic system (PV systems) uses solar panels to convert sunlight into electricity. Maximum Power Point Technique (MPPT) is mostly used to measure the efficiency PV system. The main objective of MPPT is to process data (Voltage and current) accumulated from the PV array and propose the proper resistance to get maximum power under any environmental conditions. In this paper we have designed and developed new algorithm for finding the Maximum Power Point of PV cell by hybridizing the usual techniques for finding the maximum power point that are “Perturb and Observe” and “Incremental conductance” to overcome their advantages and disadvantage which they have over each other. Moreover designed algorithm is developed using matlab and will be validate using real time data from the PV cell and the output will be compared with current algorithms
Diffusion of the rejuvenators into bitumen studied by FTIR-ATR as a function of temperature and bitumen properties
The ageing of bitumen reduces the ductility of pavement and results in material hardness. Generally, recycling of asphalt is carried out to reduce the negative impact of ageing. In a conventional hot-mix asphalt recycling process, the bitumen from asphalt pavement is blended with the aggregates and rejuvenating agent.
During the recycling process, all materials are mixed at particular temperature for a short period of time. To achieve high quality recycled asphalt mix, proper blending of aged bitumen with added rejuvenator is necessary for effective performance. The role of rejuvenator to reduce the stiffness of aged bitumen is essentially governed by the diffusion of its molecules into the bitumen. Diffusion is a slow occurring process and largely depends on temperature and intermolecular interactions of diffusing molecules
The primary objective of this thesis was to examine the factors limiting the maximum degree of rejuvenation within the realistic time frame, similar to that observed in field. Temperature, viscosity and softening properties of materials were analyzed specifically to deduce their influence on the diffusion of rejuvenating molecules.
Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) was applied to monitor the diffusion of rejuvenator in two different grades of bitumen. The degree of rejuvenation was found to increase with temperature. However, below the softening point of the bitumen, rejuvenation was not visibly proceeding. The rejuvenation level was also found to increase with decreasing viscosity of the rejuvenating agent

Design of a non-invasive device to measure bone strength recovery of distal radius fractures for use with HR-pQCT Imaging
Distal radius fractures are the most common bone injury in adults, with the majority occurring in postmenopausal women. Often these fractures result in painful healing defects, leading to extended treatment and even surgery. Currently, there is no clinical method to quantify the extent of bone healing beyond the limited capabilities of standard x-rays. The goal of this project is to develop a device, which can determine the strength of a healing fracture. This is achieved by applying a known bending load to the distal radius and measuring the displacement of the bone in High Resolution CT images. The device created was manufactured via 3D printing. Validation of device performance was performed using cadaver wrist models
Religion as a barrier to the use of student loans for higher education:a community‐based participatory study with Somalis living in England
The unwillingness of the Somali community to finance higher education has largely gone unnoticed within the academic literature and government policy documents. This study explores the role of religion and the influence of Shari'ah scholars on the use of interest‐bearing student loans within the Somali community. In the absence of any theoretical framework on this topic, we explore the multiple socioeconomic factors that may influence the attitude, perception of need, motivation and action of using student loans for higher education, by proposing the UK Somali Muslims Acceptance of Interest‐bearing Student Loan Model. This is also a community‐based participatory study that actively involved Somali community members in exploring and interpreting the results. This was achieved through regular consultations with the sampled Somali Muslim communities within the UK. Our results contribute to the broader debate on the effect of cultural, religious and social values of marginalised communities on inclusion and widening access policies for higher education. The findings reemphasise that people sharing the same location do not necessarily share the same level of opportunities for higher education because of the intersectionality of race, religion, gender and class. The results also show the complexity of the issue of exclusion and the atheoretical nature of student loans as a financial instrument for improving financial inclusion and widening access to higher education among Somali residents in England
In-between belongings:impact of Covid-19 pandemic on the lives of Syrian refugees in Scotland
This event explores the co-existence of multiple and radically distinctive rhythmic worlds of Syrian refugees resettling in Scotland during the pandemic. The event is based on the findings of a research project that applies rhythmanalysis as a bio-social perspective that goes beyond the legal, ideological and material category of ‘refugee’, during the pandemic that placed refugees at a radical disjuncture from their historically-formed habitus of the society of emigration.Participants were asked to visually document and audially reflect on their spatial and extra-spatial encounters of everyday life. The data re-presents the suturing of a fractured habitus and broken rhythms of everyday life during the pandemic. The realities of lockdown and the social experiences post-Covid resulted in a continuous cycle of formation, deformation, reformation of everyday rhythms in the daily lives of Syrian Refugees. An overarching theme of ‘emptiness’ emerged of a (temporarily) frozen time and space suffused with nostalgia for what once was and paralysis of what now is – a longing for belonging and home, as well as hopeful constructions of place-making in the society of immigration

Noise-Crypt: Image Encryption with Non-linear Noise, Hybrid Chaotic Maps, and Hashing
To secure the digital images over insecure transmission channels, a new image
encryption algorithm Noise-Crypt is proposed in this paper. Noise-Crypt
integrates non-linear random noise, hybrid chaotic maps, and SHA-256 hashing
algorithm. The utilized hybrid chaotic maps are the logistic-tent and the
logistic-sine-cosine map. The hybrid chaotic maps enhance the pseudorandom
sequence generation and selection of substitution boxes, while the
logistic-sine-cosine map induces non-linearity in the algorithm through random
noise. This deliberate inclusion of noise contributes to increased resistance
against cryptanalysis. The proposed scheme has been evaluated for several
security parameters, such as differential attacks, entropy, correlation, etc.
Extensive evaluation demonstrates the efficacy of the proposed scheme, with
almost ideal values of entropy of 7.99 and correlation of -0.0040. Results of
the security analysis validate the potency of the proposed scheme in achieving
robust image encryption
