This paper presents an additive watermarking technique for grey-scale pictures. It consists in secretly embedding copyright information (a binary code) into the picture without degrading its quality. Those bits are encoded through the phase of maximal length sequences (MLS). MLS are binary sequences with good correlation properties. The result of the autocorrelation is much greater than crosscorrelations, i.e. correlations made with shifted versions of this sequence. The embedded bits are retrieved from the result of the correlations. The core of the embedding process is underlaid by a masking criterion that guarantees the invisibility of the watermark. It is combined with an edge and texture discrimination to determine the embedding level of the MLS, whose bits are actually spread over 32;8 pixel blocks. Eventually, some results are presented, which analyze the efficiency of the retrieval as well as the resistance of the watermark to compression and its robustness against malevolent manipulation. 1998 Elsevier Science B.V.

In this paper, we wish to present a process enabling to mark digital pictures with invisible and undetectable secret information. This so-called watermarking process is intended to be the basis of a complete copyright protection system. It consists in constructing a band-limited image from binary sequences with good correlation properties and in modulating some randomly selected carriers. The security relies on the secrecy of these carrier frequencies, which are deduced from a unique secret key. Then the amplitude of the modulated images is modi ed according to a masking criterion based on a model of the Human Visual System. The adding of the modulated images to the original is supposed to be invisible. The resulting image fully identi es the Copyright Owner since he is the only one able to detect and prove the presence of the embedded watermark thanks to his secret key. This paper also contains an analysis of the robustness of the watermark against compression and image processing.

Memory represents a major bottleneck in embedded systems. For multimedia applications bulky of data in these embedded systems require shared memory. But the integration of this kind of memory implies some architectural modifications and code transformations. And no automatic tool exists allowing designers to integrate shared memory in the SoC design flow. In this work, we present a systematic approach for the design of shared memory architectures for application-specific multiprocessor systems-on-chip. This work focuses on the code-transformations related to the integration of a shared memory.

Modern embedded systems need to support multiple time-constrained multimedia applications that often employ multiprocessor-systems-on-chip (MPSoCs). Such systems need to be optimized for resource usage and energy consumption. It is well understood that a design-time approach cannot provide timing guarantees for all the applications due to its inability to cater for dynamism in applications. However, a runtime approach consumes large computation requirements at runtime and hence may not lend well to constrained-aware mapping. In this article, we present a hybrid approach for efficient mapping of applications in such systems. For each application to be supported in the system, the approach performs extensive design-space exploration (DSE) at design time to derive multiple design points representing throughput and energy consumption at different resource combinations. One of these points is selected at runtime efficiently, depending upon the desired throughput while optimizing for ener...

Real-timedisk scheduling (RTDS) is important for time-critical multimediaapplications. In conventional approaches of real-time disk scheduling,such as SCAN-EDF, the seek-optimizing SCAN scheme is appliedto reduce the disk service time of the real-time EDF schedule.Since only tasks with the same deadline are seek-optimized, theobtained improvement of SCAN-EDF is limited. In this paper, basedon the maximum-scannable-group (MSG) concept, a deadline-modification-scan (DMS or DM-SCAN) algorithm is proposed.Our algorithm uses MSG to automatically decide the suitable taskgroups for seek-optimizing. Based on the MSG concept, we repeatedlyapply DMS to further increase disk throughput to support moretasks. We have implemented the proposed algorithm on UnixWare2.01. The appropriate problem behaviors and parameter valuesto yield good solutions are investigated. Experiments show thatDMS is better than conventional approaches in both the obtaineddisk throughput and the supported tasks. Moreover, ...

This paper presents the SICMA Multimedia Information Server that was demonstrated during the first public trial of the ACTS project SICMA, which took place at the Natural History Museum of London and in the Gallo Romeins Museum of Tongeren (Belgium), from June to September of 1997. The demonstrator application, namely the "Virtual Museum", is also presented. The SICMA server complies to the DAVIC standard and is built on top of the KYDONIA multimedia information server. Core DAVIC Server Service elements (Service Gateway, Stream, Content, File) have been developed and the DAVIC User Plane information flows (S1 and $2) are supported. In this paper we describe the overall SICMA server architecture and explain the main factors that lead to server design. We also identify the critical points which affected the overall system performance and determined the degree of compliancy with the accepted standards, such as DAVIC.

This paper describes the development of a multimedia information server that supports state-of-the-art distributed applications. This is achieved through techniques for efficient storage management of large objects, the provision of real-time data pumps controlled by scheduling mechanisms, multimedia object modelling and ODBMS functionality for the manipulation of objects. The system delivers MPEG-2 video and audio streams to multiple clients and supports browsing on the components of HTML documents and on MPEG-2 video sequences. The server functionality is exported as a proprietary application development interface in a sophisticated client subsystem. Current research focus is on content-based browsing and retrieval techniques as well as for the completion of the implementation of the DAVIC-compliant server functionality of the system.

High efficiency video coding (HEVC) is the newest video codec to increase significantly the coding efficiency of its ancestor H.264/Advance Video Coding. However, the HEVC delivers a highly increased computation complexity. In this paper, a coding unit partitioning pattern optimization method based on particle swarm optimization (PSO) is proposed to reduce the computational complexity of hierarchical quadtree-based coding unit partitioning. The required coding unit partitioning pattern for exhaustive partitioning and the rate distortion cost are efficiently considered as the chromosome and the fitness function of the PSO, respectively. To reduce the computational time, the cellular automata-based (CA) rule based time limit is used in order to find out the best possible modes of operation. Compared to the current state of the art algorithms, this scheme is computationally simple and achieves superior reconstructed video quality (12% increase in PSNR compared to existing methods) at less computational complexity (overall delay by 40%), Increasing the bandwidth and reducing the errors..

Trend is growing towards using complex multimedia functions on smaller devices. In this study, we explore the effect of migrating legacy signal processing software applications algorithms from large form factor devices to the smaller one such as handheld mobile devices known as Energy Conscious Mobile Computing Systems (EConMCS). We concentrate on Source Code Volatility (SCV), including inherent algorithm complexity and the developer implementation. We identify code Transformation Steering Factors (TSF), such as loop unrolling factor, decision tree grafting factor and their relation to SCV. The impact of TSF is discussed for different multimedia applications in native Digital Signal Processor (DSP) compiler optimization while switching between different transformation schemes. Our results show that SCV can be minimized by using an architecture-centric algorithm that both enables the effective use of underlying hardware architectures and the memory access required to optimize energy consumption. The coded spatial access is implicitly dependent on layout, content and location of options and legibility that relates to a developer's implementation of loops, code blocks and decision trees. The compiler-centric transformation model minimizes the effect of legacy code migration for multimedia applications. Results are exposed for the transformation of typical DSP applications and a video transcodec MPEG-4.

Handheld embedded systems are crucial to obtain high performance for execution time as well as efficient battery usage. Unfortunately, most of the compilation techniques to obtain an efficient binary code for complex multimedia processors lack the optimal energy-cycle code. This work describes the methodology of the compilation for next generation handheld devices, which will support datacompute intensive applications at small form factors. We designed and implemented optimization framework which supports conventional code optimization scheme along with additional energy efficient benefits for multimedia applications such as MPEG-2 transcodec, H-264L transcodec. Optimization space is searched with genetic algorithm. Whole scheme reduces energy, on both as per cycle basis and as the total energy used over the lifetime of an application. The optimized G-728 audio codec meets realtime constraints on the Nexperia series of multimedia processor with low energy consumption. Furthermore, the performance improves by a factor of 0.489 and the energy consumption decreases by a factor of 0.203 over the baseline executable code.

Deep Learning based Fast Mode Decision in HEVC Intra Prediction using Region Wise Feature Classification SHIBA KUANAR, Ph.D. The University of Texas at Arlington, 2018 Supervising Professor: K.R. Rao The High Efficiency Video Coding (HEVC) standard has achieved best coding efficiency as compared to previous H.264/AVC standard. But the computational time of HEVC encoder has increased mainly because of the hierarchical quad-tree based structure, recursive search for finding the best coding units, and the exhaustive prediction search up-to 35 modes. These advances improve the coding efficiency, but result into a very high computational complexity. Furthermore selecting the optimal modes among all prediction modes are necessary for the subsequent rate distortion optimization process. Therefore we propose a convolutional neural network (CNN) based algorithm which learns the region wise image features and performs a classification job. These classification results are later used in the en...

This paper explores how knowledge management (KM) through information and communication technologies (ICTs) can foster Internet-based digital innovation in the public sector in Bangladesh. A total of twelve semi-structured interviews were conducted with relevant persons in four government organizations. Findings reveal that there are huge unexplored areas where ICT can be utilized for the creation, storage and dissemination of knowledge. By reducing time, cost & movement ICT-utilized KM can promote ICT-led innovation. The main barrier of ICT-led KM initiatives is the lack of awareness of the government officials. This study is an extension of the previous findings. It contributes significantly to a better understanding of ICT's integration with KM and innovation. It suggests that one of the core functions of ICT in the public offices is to manage knowledge. The paper offers some insights into how in a digital environment, knowledge can be innovatively managed in the public sector organizations.

The concept of blended learning is not new. While research articles have outlined blending learning approaches across a number of disciplines, research studies on how blended learning design principles are implemented into existing modules in the discipline of multimedia studies are limited. This research aims to address that gap by critically evaluating the integration of a blended learning approach into a multimedia applications module. The blended approach adopted is a pedagogical one which integrates synchronous online lectures with face-to-face learning in computer laboratories. Lecturers can determine whether a synchronous blended learning pedagogy is relevant to their own discipline and teaching practice by accessing this research. Objectives of the study include a critical review of the existing literature relating to blended learning and student experiences of blended learning in higher education (HE). A responsive case study is conducted to evaluate the effectiveness of integrating a blended learning approach into a multimedia applications module within GMIT and to evaluate the student learning experience. The methodology adopted for this study combines constructivism and pragmatism as a basis for a mixed methods design using a single responsive case study. The key areas examined in this study include introduction, literature review, methodology, design of the new blended module, research findings and analysis, conclusion and recommendations. Overall research findings indicate positive perceptions of the blend adopted in the areas of pedagogical, social and technical design. The results are also positive in relation to perceived differences in modes of delivery. Findings suggest that the optimum blend has been reached in that theory is delivered synchronously online and students also have face-to-face practical classes in laboratories. Results in relation to whether students learn more in the synchronous online lecture than if it was delivered face-to-face are inconclusive. Further research is recommended in this area.

This paper intends to analyze subjective measurements of intelligibility of speech on Albanian language during the conversation between two people using applications which today are very used for communication such as Skype and Viber. The measurement is done as follows: on the entry part of the transmission system sentences or words are spoken or just syllables while on receiving part is recorded what is heard; the percentage of words, sentences or syllables correctly received, on proportion to those imposed on the entry of the system, providing the percentage of intelligibility (the words, sentences or syllables). Methods of measurements are made at different speed of the Internet, in an environment without noise and with noise, in order to see the impact on understanding of the speech with different target parameters.

The results achieved by the students show that the course succeeded in keeping different kinds of students engaged and excited with the implementation of their final project.

The provision of interactive m ultimedia services, such a s video-on-demand, teleshoping and distance learning, to a large number of users, still remains a challenging issue in the multimedia area. Despite of recent t e c hnological advances in all levels of the distributed multimedia infrastructure (storage, network, compression, standardization etc..), there is a strong need for feedback from public trials. Trial descriptions and evaluations, by revealing potential system limitations and measuring end user reactions, will provide valuable input towards the large-scale deployment o f s u c h services. In this paper, we present the teleteaching trial that was held at the end of 1998, at Limburg University (Belgium), in the context of ACTS SICMA project. We describe in detail the overall architecture and present results/implementation experiences for the parts of the system, putting the main emphasis on the server. We present t e c hnical integration issues between DAVIC and Internet server protocols (RTSP, DSM-CC etc..), and discuss the overall trial results.

Extension agents are encouraged to use new technologies to reach and teach their clientele. To uncover the prevalence and effectiveness of technology use, a survey was conducted among family and consumer sciences agents in the southern region of the United States. The results show that there is not much deviation from PowerPoint presentations, though some additional multimedia is incorporated. Barriers and advantages of using educational technology are discussed.

Quantum image computing draws a lot of attention due to storing and processing image data faster than classical. With increasing the image size, the number of connections also increases, leading to the circuit complex. Therefore, efficient quantum image representation and compression issues are still challenging. The encoding of images for representation and compression in quantum systems is different from classical ones. In quantum, encoding of position is more concerned which is the major difference from the classical. In this paper, a novel zero-discarded state connection novel enhance quantum representation (ZSCNEQR) approach is introduced to reduce complexity further by discarding '0' in the location representation information. In the control operational gate, only input '1' contribute to its output thus, discarding zero makes the proposed ZSCNEQR circuit more efficient. The proposed ZSCNEQR approach significantly reduced the required bit for both representation and compression. The proposed method requires 11.76% less qubits compared to the recent existing method. The results show that the proposed approach is highly effective for representing and compressing images compared to the two relevant existing methods in terms of rate-distortion performance.

Quantum image processing draws a lot of attention due to faster data computation and storage compared to classical data processing systems. Converting classical image data into the quantum domain and state label preparation complexity is still a challenging issue. The existing techniques normally connect the pixel values and the state position directly. Recently, the EFRQI (efficient flexible representation of the quantum image) approach uses an auxiliary qubit that connects the pixel-representing qubits to the state position qubits via Toffoli gates to reduce state connection. Due to the twice use of Toffoli gates for each pixel connection still it requires a significant number of bits to connect each pixel value. In this paper, we propose a new SCMFRQI (state connection modification FRQI) approach for further reducing the required bits by modifying the state connection using a reset gate rather than repeating the use of the same Toffoli gate connection as a reset gate. Moreover, unlike other existing methods, we compress images using block-level for further reduction of required qubits. The experimental results confirm that the proposed method outperforms the existing methods in terms of both image representation and compression points of view.

Quantum computing draws huge attention due to its faster computational capability compared to classical computing to represent and compress the classical image data into the quantum domain. The main idea of quantum domain representation is to convert pixel intensities and their coordinates i.e. state label preparation using quantum bits i.e. Qubits. For a bigger size image, the state label preparation takes more Qubits. To address more Qubits issues, a novel SCMNEQR (State Connection Modification Novel Enhanced Quantum Representation) approach has been proposed that uses fewer qubits to map the arbitrary size of the grayscale image using block-wise state label preparation. The proposed SCMNEQR approach introduces the state connection using a reset gate rather than repeating the use of the Toffoli gate used in the existing approach. The experimental results show that the proposed approach outperforms the existing methods in terms of compression.

Recent Technological advances in Wireless Communication has shown the convergence of terminals and networks that support multimedia and real-time applications. This obviously puts an immense pressure on battery of any mobile device. The CMOS has been the leading technology in today's world of mobile communication due to its low power consumption. Reduction of leakage power in CMOS has been the research interest for the last couple of years. In CMOS integrated circuit design there is an important trade-off between technology scaling and static power consumption. In today's CMOS technology the leakage power consumption plays a significant role. As we approaching to nano-scale design the total chip power consumption becomes dependent on leakage power. Increasing the battery life in mobile wireless communication and mobile computing and similar other applications is the topic of research now-a days... Further, since the leakage of battery exists even when devices are in idle state makes leakage power loss most critical in CMOS VLSI circuits. Many techniques have been evolved to tackle the problem and its still in progress. This paper mainly focuses on the review of various works done in this field till today's date. Further a review of recent work done on a new technique LSSR (Lector Stack State Retention Technique) is discussed in the paper.

The Makaton Vocabulary Development Project is a widely used communication system designed for individuals with speech and communication disabilities. It enables educators to teach students how to communicate alternatively through selection and combination of visual representations, symbols, words, gestures and sounds. Our analysis has indicated various difficulties that arise in the manual application of the above system, as customisation to individual student-needs is needed, presenting a complex and time-consuming task for the educator. This paper presents the development of a novel communication environment that permits students to use the Makaton method through an open media-rich, adaptable easily extendable interactive multimedia application. The environment is tested in two focus groups and the results and observations are discussed. The method of knowledge-base extension is presented, targeting the development of an internet-based virtual learning environment for special needs.

This paper report on recent and on going work related to the design of a set of hypermedia authoring tools intended to produce courseware, to be used for self learning or distance learning and training environments in a cooperative way. These tools have roots in a standalone hypermedia editor developed to create courseware, to which were added other tools to enhance its usability, namely a hypermedia player to view courseware in self study mode, and a hypermedia browser to create, to navigate and to display graphically the hypermedia document structure. The underlying metaphors are the overhead projector, the transparency and the layer. This system was developed for the MS-Windows environment, supporting OLE technology. We discuss the impact that such technology might have on the "look and feel" of hypermedia learning material and we describe the implementation of a Hypermedia Editor, Browser and Player tools. Part of this work is carded out in the context of the Co-Learn European project, which is aiming to design and to implement a third generation cooperative learning environment.

The analysis of multimedia application traces can reveal important information to enhance program comprehension. However traces can be very large, which hinders their effective exploitation. In this paper, we study the problem of finding a k-golden set of blocks that best characterize data. Sequential pattern mining can help to automatically discover the blocks, and we called k-golden set, a set of k blocks that maximally covers the trace. These kind of blocks can simplify the exploration of large traces by allowing programmers to see an abstraction instead of low-level events. We propose an approach for mining golden blocks and finding coverage of frames. The experiments carried out on video and audio application decoding show very promising results.

Computer graphic courses are pretty established in most computer graphics degrees worldwide. Distance learning has been gaining popularity as fast internet access from home has been reaching wider areas around the world. If we combine this with the fact that the popularity of video games all over the world has made the technology required for rendering real time graphics widely available and affordable, we have the perfect environment for teaching computer graphics through distance learning universities. In this paper, we explain our experience in teaching Computer Graphics basics for the last 10 years at the distance teaching university Universitat Oberta de Catalunya (UOC). By using materials that include interactive applets which allow the student to play with basic Computer Graphics concepts, we observe that students can understand the course despite the teacher not being present in the learning process.

Security of medical media is important for patient safety and confidentiality. This paper proposes a framework for the chaos-based quantum encryption of healthcare images. In the framework, healthcare staff in one location send cipher images to the cloud. The healthcare staff in another location receives the images from the cloud. By decrypting the content of the images, the healthcare staff can assist users in a secure manner. This paper also proposes a novel approach for the efficient quantum image encryption of healthcare media. The proposed algorithm utilizes gray code and a chaotic map. The quantum image is scrambled by quantum gray code. Then, the scrambled quantum image is encrypted using a quantum XOR operation based on a key generator controlled by the logistic-sine map. The circuits of the proposed encryption/decryption algorithm are devised based on an NEQR quantum image representation. Numerical and simulation analyses show that the proposed quantum image encryption approach is robust, realizable, and has high efficiency compared with its classical counterpart. INDEX TERMS Quantum image encryption, chaotic systems, healthcare.

The analysis of multimedia application traces can reveal important information to enhance program execution comprehension. However typical size of traces can be in gigabytes, which hinders their effective exploitation by application developers. In this paper, we study the problem of finding a set of sequences of events that allows a reduced-size rewriting of the original trace. These sequences of events, that we call blocks, can simplify the exploration of large execution traces by allowing application developers to see an abstraction instead of low-level events. The problem of computing such set of blocks is NP-hard and naive approaches lead to prohibitive running times that prevent analysing real world traces. We propose a novel algorithm that directly mines the set of blocks. Our experiments show that our algorithm can analyse real traces of up to two hours of video. We also show experimentally the quality of the set of blocks proposed, and the interest of the rewriting to understand actual trace data.

A generalization of the correlation function is explored which, besides a relative time shift between the signals to be correlated, also takes into account different scalings on the time axis (i.e., magnification/reduction). It is shown how the generalized correlation function for continous signals can be sampled and computed without loss of information and thus can be described by discrete-time signals. Envisaged applications comprise coded aperture imaging, measurement, radar, and digital communications. Special attention is paid to tomo-graphic imaging using coded apertures. It is demonstrated how individual slices of an object can be reconstructed by correlating the recorded image with suitably designed decoding filters using the generalized correlation function.

Ontologies currently are a hot topic in the areas of Semantic Web. The current clustering research emphasizes the development of a more efficient clustering method and mainly focuses on term weight calculation without considering the domain knowledge. This paper investigates how ontologies can also be applied to the clustering process. To complement the traditional clustering method, more informative features including concept weight are important based on recent developments in the area of the Semantic technologies. The proposed system presents the concept weight for text clustering system developed based on a k-means algorithm in accordance with the principles of ontology so that the important of words of a cluster can be identified by the weighted values. To a certain extent, it has resolved the semantic progeny in specific areas. The experimental results performed using dissertations papers from Google Search Engine and the proposed method demonstrated its effectiveness and practical value.

Technological advances in computing have allowed multimedia systems to create more immersive experiences for users. Beyond the traditional senses of sight and hearing, researchers have observed that the use of smell, taste, and touch in such systems is becoming increasingly well-received, leading to a new category of multimedia systems called mulsemedia-multiple sensorial media-systems. In parallel, these systems introduce heterogeneous technologies to deliver different sensory effects such as lighting, wind, vibration, and smell, under varied conditions and restrictions. This new paradigm shift poses many challenges, mainly related to mulsemedia integration, delay, responsiveness, sensory effects intensities, wearable and other heterogeneous devices for delivering sensory effects, and remote delivery of mulsemedia components. In addition, new approaches to interacting with multimedia applications have emerged such as multi-touch interfaces, voice processing, and brain-computer interfaces, giving rise to new kinds of complex interactive systems. In this article, we underpin fundamental challenges for delivering multisensory effects to heterogeneous systems. We propose an interoperable mulsemedia framework for coping with these challenges, meeting the emerging requirements. It is achieved through the evolution of an open distributed mulsemedia system. We changed its core following architectural and design patterns to accommodate different profiles of communication, connectivity, and sensory effects metadata standard according to the need of mulsemedia applications and devices available in the user's environment. The results include case studies where the framework has been duly applied.

Heart rate is an important vital sign used in the diagnosis of many medical conditions. Conventionally, heart rate is measured using a medical device such as pulse oxymeter. Physiological parameters such as heart rate bear a correlation to speech characteristics of an individual. Hence, there is a possibility to measure heart rate from speech signals using machine learning and deep learning, which would also allow non-invasive, non contact based and remote monitoring of patients. However, to design such a scheme and verify its accuracy, it is necessary to collect speech recordings along with heart rates measured using a medical device, simultaneously during the recording

Multimedia applications with stringent delay requirements are usually supported by the CBR or rt-VBR service categories of ATM. This article shows that ABR service, which was originally designed for data, can also support multimedia applications under certain circumstances. Issues related to the design of proper ABR traffic management algorithms for such support are presented.

Microservices Architectures (MSAs) are continuously replacing monolithic systems toward achieving more flexible and maintainable service-oriented software systems. However, the shift toward an MSA also requires a technological and managerial shift for its adopters. Architecting and managing MSAs represent unique challenges, including microservices' identification, interoperability, and reuse. To handle these challenges, we propose an Ontology-driven Conceptual Modelling approach, based on the Ontology of Microservices Architecture Concepts (OMSAC), for modelling and analyzing microservices-based systems. We show, how OMSACbased conceptual models, stocked in a Stardog triple store, support Stakeholder-specific communication, documentation, and reuse. This paper reports on the application of our approach in three open-source MSA systems with a focus on microservices' discovery based on similarity metrics. Eventually, we compare the extracted similarity metrics derived from the application of machine learning techniques to the OMSAC models with a manual analysis performed by experts.

Due to the appearance of auto-stereoscopic visualization as one of the most emerging tendencies used in displays, new content generation techniques for this kind of visualization are required. In this paper we present a study for the generation of multi-view synthetic content, studying several camera setups (planar, cylindrical and hyperbolic) and their configurations. We discuss the different effects obtained varying the parameters of these setups. A study with several users was made to analyze visual perceptions, asking them for their optimal visualization. To create the virtual content, a multiview system has been integrated in a powerful game engine, which allows us to use the latest graphics hardware advances. This integration is detailed and several demos and videos are attached with this paper, which represent a virtual world for auto-stereoscopic displays and the same scenario in a two-view anaglyph representation for being visualized in any conventional display. In all these demos, the parameters studied can be modified offering the possibility of easily appreciate their effects in a virtual scene.

In the continuous scaling down of technology in the field of integrated circuits, low power circuits are in demand for reliability and performance. This research focuses on run time leakage reduction technique for CMOS devices, this work introduces two well known approaches, stack approach with pass transistor approach for reduction of the leakage power and improves the performance of the circuit. Here NMOS transistor and PMOS transistor parallel to each other in between pull up and pull down network, the resistance is increased by providing stacking of the transistor for mitigation of leakage power. For proper validation and verification of results we use the module of proposed NAND gate to built a Full Adder circuit and for verification of results. Here NMOS pass transistor is connected between pull up network and pull down network similarly PMOS transistor is also connected between pull up network and pull down netwotk both NMOS and PMOS pass transistor are self controlling transistor whch reduces the power consumption in active and ideal mode at 43.33%, 43.33%, 86.07% and 86.04% at 25oC respectively as compared with the standard 2 input NOT,AND,NAND and NOR gates. Average dynamic power is reduced to 14.
