AAKE-BIVT: Anonymous authenticated key exchange scheme for blockchain-enabled internet of vehicles in smart transportation
Full text linkThe next-generation Internet of vehicles (IoVs) seamlessly connects humans, vehicles, roadside units (RSUs), and service platforms, to improve road safety, enhance transit efficiency, and deliver comfort while conserving the environment. Currently, numerous entities communicate in the IoVs environment via insecure public channels that are susceptible to a variety of security assaults and threats. To address these security challenges, we design an anonymous authenticated key exchange mechanism for the IoVs in smart transportation supported by blockchain, referred to as AAKE-BIVT. AAKE-BIVT securely transmits traffic information to a cluster head, before heading to a nearby RSU utilizing the established secret session keys via mutual authentication and key agreement. A cloud server (CS) then securely aggregates data from related RSUs and generates transactions. The CS combines the transactions into blocks in a peer-to-peer network of CSs, and the blocks are confirmed and added to the blockchain via a voting-based consensus method. By means of rigorous informal security studies and formal security analysis through the random oracle model, we reveal that the proposed AAKE-BIVT is resistant to a broad range of potential security assaults in the IoVs environment. Furthermore, a comparative study reveals that AAKE-BIVT outperforms existing state-of-the-art techniques, in terms of security and functionality while being more efficient in terms of communication and computation. Additionally, the blockchain simulation validates the implementation viability of our proposed AAKE-BIVT
USAF-IoD: ultralightweight and secure authenticated key agreement framework for internet of drones environment
Full text linkThe use of Internet of Drones (IoD) technology has surged across various domains such as logistics, surveying, industrial inspections, emergency response, security, infrastructure monitoring, crop management, and more. However, realtime communication with drones or Unmanned Aerial Vehicles (UAVs) in the IoD environment occurs over an insecure open channel, making it susceptible to various security and privacy vulnerabilities, including unauthorized access, data interception, denial of service attacks, and privacy concerns. Due to their unique characteristics, including long transmission distances, unstable communication environments, resource limitations, and the highly dynamic nature of UAVs, ensuring the security and privacy of IoD systems is of paramount importance for the success of IoD-based applications. Furthermore, drones are resourceconstrained devices, and employing expensive security solutions is impractical, as it would significantly reduce the operational capacity of drones. In this paper, we present the design of an ultralightweight, secure, and robust user-authenticated key agreement framework for the IoD environment, named USAF-IoD. The proposed USAF-IoD is developed by incorporating authenticated encryption (ASCON), cryptographic hashing, XOR operations, and the use of physical unclonable functions (PUFs). PUFs are employed to enhance resistance against physical tampering attacks. The security analysis reveals that the proposed USAF-IoD meets the essential security requirements of the IoD environment. The comparative analysis further highlights the effectiveness of the proposed USAF-IoD, notably excelling in terms of security and functionality characteristics when compared to existing benchmark schemes, and showcasing competitive performance in computation, communication, and energy overheads
Akhtar Raza Saleemi as a Poet
Full text link Akhtar Raza Saleemi was brought into the world on 16 June 1974, at Kekot Khyber Pakhtunkhwa, Pakistan. He accepted his primer schooling in his own town and learnt Urdu, Persian and so on at an early age. Later he moved to Karachi for where he rehashed his registration and Intermediate. He moved to Islamabad for higher examinations and finished his graduation from the renowned Allama Iqbal College. Akhtar was basically a writer of the ghazal custom anyway he confined himself from being a generalization and examination his abilities in other sort of writing like nazam, fiction, novel and so forth. His verse assortments \u27Khawab Daan\u27 has been applauded by the pundits. Akhtar Raza saleemi is a perceived writer of both ghazal and nazm. He has distributed a few verse books and has been valued for his work by pundits. He remained in the class of verse till 2008 and afterward began exploring different avenues regarding the style of novel composition. His verse being viewed as a particular mix of dream and reality.

Metadiscursive Role of Author(s)’s Exclusive Pronouns in Pakistani Research Discourses
No full textExploiting author(s)’s exclusivity in academic and research discourses has been manifested with various viewpoints within the broader spectrum of formality versus informality, subjectivity versus objectivity, and self-display versus self-effacement. The interpersonal role of self-mentioning from metadiscursive perspective of text and reader orientedness has been neglected in this whole debate. The current study explores these metadiscursive functions of author(s)’s exclusive pronouns in 104 research articles published in Pakistani research journals from hard and soft fields in order to establish their metadiscursive role in research discourses especially. This role, furthermore, determines the extent of association/affinity of these pronouns with Hyland’s (2005) interactive and interactional categories of metadiscourse. There were 308 metadiscursive author(s)’s exclusive pronouns found performing 464 interpersonal functions of metadiscourse revealing multifunctional nature of these pronouns. Firstly, interactive affinity of author(s)’s exclusivity was found more than interactional association with frequency of 291 and 173 respectively. Secondly, among interactive roles, framing discourse (Frame Markers i.e., FM) through these pronouns is the most visible schematic pattern with the value of 48%. On the other hand, thirdly, Boosters i.e., BST, among interactional metadiscourse, in associative behavior with author(s)’s exclusive pronouns occur with highest rate i.e., 55%. Finally, author(s)’s exclusive pronouns were observed to be showing bi-covalent and tri-covalent metadiscursive bond suggesting multifunctional interpersonal role of author(s)’s exclusivity. In the light of these findings, we suggest an Associative Interpersonal Model of Author(s)’s Exclusivity (AIMAE) which is promising in exploring author(s)’s affinity with certain cognitive patterns of metadiscursive interaction.</jats:p

Performance evaluation of novel Ca/Mn-doped perovskite as a multifunctional material in chemical looping reverse water gas shift process for low-carbon fuels
No full textThe chemical looping reverse water gas shift (CL-RWGS) catalytic process offers a promising approach for decarbonizing energy-intensive industries. The CL-RWGS promotes the formation of surface oxygen vacancies in the material, which are subsequently replenished by extracting oxygen from CO2, resulting in syngas production. However, there remains a significant gap in the development of materials that not only exhibit redox activity but also enable in-situ carbonation, offering dual functionality for enhanced CO2 utilization. This study introduces a novel calcium- and manganese-doped LaNiO3 perovskite, designed for integrated CO2 sorption and in-situ utilization during CL–RWGS process. Comprehensive characterization confirmed the material’s crystalline structure, porosity, and successful incorporation of Ca and Mn dopants. Thermogravimetric analysis (TGA) across 700 – 900 ◦C revealed a peak oxygen storage capacity of 1.97 mmol O2/g and demonstrated excellent redox stability, with less than 1 % performance loss over 17 cycles. RWGS experiments conducted in a packed bed reactor demonstrated up to 57 % CO2 to CO conversion at 900 ◦C, approaching the thermodynamic equilibrium value of 60 % under the same operating conditions. Moreover, an H2/CO molar ratio of ~2.0, suitable for Fischer-Tropsch synthesis, was achieved at 600 ◦C and 1.0 bar with a feed H2/CO2 molar ratio of 1.0, attributed to CO2 chemisorption via a carbonation-driven mechanism facilitated by the presence of CaO phase. These results suggest that the calcium- and manganese-doped LaNiO3 perovskite is a highly promising multi-functional material for chemical looping-based CO2 utilization technologies

Reason: ETDs are only available to UIUC Users without author permissionThis thesis focusses on the life and work of one of India's most famous female singers, Begum Akhtar (1914-1974). On the one hand, it provides a brief biography and a summary of her musical accomplishments; particular attention is paid to her contributions to the genre for which she was most renowned, a musical-poetic form known as the underbar ghazal. Further to this, however, the thesis examines the manner in which the establishment of and alterations in gender roles and hierarchies, in coordination with other power relationships-- particularly those involving class and patronage shifts, moral issues, ethnic/religious concerns, and nationalist versus colonialist ideologies--affected her life and work, as well as attitudes regarding the woman and her art.Akhtar lived through a period of rapid and structural change in Indian society. Her life overlapped the transitional period in India from the pre-independence era of anti-colonial struggle to the early years of independence. Like other professional women of her class she was, coincidentally, a product of these changing times, an agent of transformation, and one of the victims. Throughout the latter part of her life Begum Akhtar bore the anguish of being caught between two moral standards, one consistent with her early role as a bai (courtesan singer) under nawabi feudal patronage, and the other with her later status as a begam in democratic India. Her dilemma, while personal, was at the same time that of a nation which, under the burden of colonial influence--in the quest for a new image and a socio-cultural, political, economic and moral restructuring--was attempting the excision of a crucial component of its own artistic self."This work presents both the dominant discourse and an alternate reading regarding a transitional period in the history of modern India, and the role that women (and particularly ""professional"" women) played within that; and it does so through a focus on the life and art of one of the leading female musical figures of the era."Made available in DSpace on 2011-05-07T13:22:37Z (GMT).

X-efficiency Analysis of Commercial Banks in Pakistan: A Preliminary Investigation
Full text linkThe emergence of a fast-paced dynamic environment in the business world in general, and in the financial services sector in particular, has highlighted the significance of competition and efficiency. The need for deregulation has become a touchstone of success in fostering both competition and efficiency especially in the economies, which are exposed to structural reforms. In addition to that, intense competition both among domestic and foreign banks, rapid speed of innovations and introduction of new financial instruments, changing consumer’s demands and desire for product augmentation have changed the way a bank conducts business and services its customers. Larger the degree of competition, it is perceived that the firms would become more efficient. However, when the structure of an industry is product of the government regulations, the degree of competition is impaired markedly implying that the efficiency suffers negatively. Banking industry acts as life-blood of modern trade and commerce acting as a bridge to provide a major source of financial intermediation. Thus, appraisal of its efficiency is vital in context of an efficient and competitive financial system. Study of x-efficiency is believed to be important in particular as Berger, et al. (1993) found that x-inefficiencies account for around 20 percent or more of banking costs. Similarly, recent drive among banks towards downsizing, rightsizing and rationalisation of banking costs also implicates for the assessment of x-efficiency analysis of banks. It becomes vital in Pakistani context as there appears to be no study in literature on efficiency or x-efficiency analysis of banks in Pakistan. “A great deal more work is needed on x-efficiency research in banking. Managerial efficiency, the concept of x-efficiency, appears to be a much more important strategic and policy consideration” [Molyneux, et al. (1960), p. 273]. Given
