Title: Impact of delay in sign language acquisition on writing development: The Case of a Deaf Child

Year: 2022 Abstract Full Paper [Download] Page:1-

Abstract: The amount of language a deaf child is exposed to during their language developmental milestones has a strong influence on their ability to write. Deaf children are frequently exposed to Bhutanese Sign Language (BhSL) at school while simultaneously learning English literacy skills. As a result, the current study employed contextualized empirical study to examine the existing knowledge to look into what is known about the impact of delayed sign language acquisition of deaf children on their writing development. This qualitative study investigated a socially constructed knowledge claim originating from an interpretivist philosophical standpoint. “Purposive criteria sampling” was used to choose the six participants. Data is collected via semi-structured interviews, participant observation, archival documents, and visual data, as well as participant observations and visual data (photovoice and videotapes). Construct validity was ensured through the triangulation of multiple sources of evidence, chains of evidence, and member checking; internal validity was ensured through the use of well-established analytic techniques like pattern matching; external validity was ensured through analytic generalization, and reliability was ensured through case study protocols and databases. The outcomes of this study, which were analyzed using thematic analysis and manually coded themes, revealed that late exposure to Bhutanese sign language has an impact on the development of linguistic structures, particularly those related to the acquisition of a written form of the second language, vocabulary, and grammatical structures. Lack of shared language, deprived incidental learning, parental support in language and literacy development, and early intervention are all factors that contribute to a better understanding of why deaf children struggle with writing competence in English and Dzongkha. The study adds to the increasing body of evidence that early exposure to Bhutanese sign language (BhSL) helps deaf children develop their writing skills. Because language and literacy are learned at the same period of time, the previous one’s competency serves as a bridge between the two.

Title: NAND Error Control approach Flash Memories: A logical approach to many approaches

Year: 2022 Abstract Full Paper [Download] Page:1-

Abstract: Due to its high overwriting concept, flash memories play a critical role in the VLSI sector for data storage. However, because of the parasitic capacitance that exists between the storage cells, errors in decoding the memory circuits occur. Many error control coding techniques have been created in information coding to repair errors, such as RS decoding, BCH decoding, and LDPC decoding, which are all utilized as error control coding in NAND flash storage. Controlling different voltage levels shows the difference between soft and hard decisions in error control strategies. The best result on various output leads is obtained by fragmenting NAND Flash into pages with a threshold and applying various techniques such as paired pages and parallel pipelined techniques. In this survey, we analyze the results of diverse approaches, strategies, tools, and techniques employed to decode NAND flash memories with various error control encodings.

Title: THE DADDA ALGORITHM: VLSI IMPLEMENTATION OF A LOW-POWER, HIGH-EFFICIENCY AND EFFECTIVE MULTIPLIER

Year: 2022 Abstract Full Paper [Download] Page:1-

Abstract: In most CPUs, the multiplier is a vital hardware component that contributes significantly to the system’s overall power consumption. The arithmetic product of two input signals produces the output state of this circuit. The two most fundamental building blocks of multipliers are a full adder and a half adder. Different design implementations of a full adder and half adder circuits have been used to produce an optimized multiplier circuit that incorporates pass transistor logic, Different multiplication algorithm strategies, such as Wallace tree multiplication, booth’s algorithm, standard array multiplier, radix-4 multiplier technique, Vedic mathematics, Dadda’s algorithm, and others, can also be utilized to create the multiplier. In this work, we compare the result with power, delay and transistor count for different techniques and methods. One of the most efficient algorithms for low-power and high-speed architectures is the Dadda algorithm. The AND gate, half adder, and full adder circuits are the key building elements of the multiplier, resulting in a reduction in overall power consumption and latency. These major building blocks will be implemented using the Hybrid (CMOS process and transmission gate logic) technique and GDI technique. The multiplier’s efficiency will next be compared in terms of power dissipation, latency, and area using Cadence tools.Andalsothe4bitmultiplierisenhanced to 8 bit multiplier using the Daddaalgorithm and thiswillbeimplementedinXilinxISEsoftwareusingVeriloglanguageandRTLschematicwillbedesigned.

Title: Conceptual and Theoretical Framework for Project Management Knowledge Area Techniques to enhance Contract Performance

Year: 2022 Abstract Full Paper [Download] Page:1-

Abstract: This paper focuses on the theoretical and conceptual frameworks used to guide the understanding of the study investigations. It identifies and explores three theories in the literature surrounding the topic of construction contract performance which include; the General systems theory, the Theory of constraints and the Agency theory. It also outlines and identifies two conceptual frameworks from previous studies that relate to the subject under study. The paper further proposes a conceptual framework aimed at addressing the research problem by depicting and operationalizing the independent, moderating and dependent variables
