Abstract :

New conducting polymer nanocomposites of poly(3,4-ethylenedioxythiophene) (PEDOT) were prepared by simple solid-state heating polymerization of 2,5-dibromo-3,4-ethylenedioxythiophene (EDOT) with different concentrations (weight percentage) of graphene nanoplatelets (GNPs). The prepared PEDOT/GNP nanocomposites were characterized through Fourier transform infrared (FTIR) and UV–vis spectroscopy, and their surface morphology was analyzed through scanning electron and transmission electron microscopy. The FTIR and UV–vis spectra revealed strong interaction between the PEDOT matrix and GNPs. The frequency-dependent AC electrical conductivity of the prepared nanocomposites was obtained at room temperature within the frequency range of 100 Hz to 2.3 × 106 Hz. The conductivity of the composites significantly increased with increasing frequency compared with that of PEDOT and GNPs.

Abstract :

This paper proposes an algorithm of power aware based on voltage islands for constructing an X-clock tree with considering double via insertion. Different voltages are assigned for multiple voltage islands for power aware to reduce total power consumption under the clock delay control. Higher rate of double via insertion is made for via-effect avoidance and reliability. We first partition a clock network to be the number of voltage islands, such as L-type or T-type, and construct the X-clock tree for each voltage island with double via insertion. Then, we combine these X-clock trees based on a well-defined connection with inserted level shifters for minimizing the power. The delay effect due to the total number of inserted double vias is also accounted. Ten benchmarks are tested for our approach. Compared with single voltage island, experimental results show that our X-clock tree based on multi-voltage islands can save up to 21.58%, 4.75%, and 33.8% in power, delay, and running time, respectively.

Abstract :

The objective of this paper is to highlight the cost and benefits of the potential contribution of lean construction to the achievement of productivity enhancement and waste minimization in construction industry. It is critical review of literature. Researcher has used exploratory method for investigating the benefits of lean construction system by exploring, and understating the available literature and some case studies.  There is need for waste minimization and enhancement of productivity in construction activity. Productivity is critical determinant of cost efficiency. The conventional system of construction is not sustainable. In one of the research it is estimated that current system of construction had around 50% of non value added efforts or waste. The meaning of lean construction is that it is the application of lean thinking to the construction industry. The construction industry and other industries also are facing various problems as a result of the uncertainties of the global economic climate, environmental hazards, including labor delayed projects and zero margin contract bids, green house gas emissions etc. The construction industry is seen as one of the worst performing industry as regards to the innovation. This calls for concern about the poor state of construction innovation. The emergence of lean construction is to bring significant reform to the construction industry to achieve the objectives of value addition and waste minimization within the built environment in the critical social, economic and environmental aspects.

Abstract :

In this work, the chemical kinetics of photosynthesis was extensively explored. Kinetic models were established. Existing data from the internet were used for the validation of the models. It was observed that the models are real and natural as they follow the growth profile nature of photosynthetic release, together with the uptake of oxygen and carbon dioxide respectively. The models actually conform to what was found in literature. Therefore photosynthetic activities could be studied using natural growth models, in conjunction with the specificities of photosynthetic phenomena. This work can be employed in the growth study of plants in agriculture, carbon cycle, and perhaps ozone layer depletion or carbon sequestration.

Abstract :

Recent advances in wireless sensor networks have generated many new protocols for clustering specifically designed for sensor networks where energy consumption is an essential consideration. Variety of sensing capabilities results in profusion of application areas. However, Sensed data need to be delivered to the base station using multihop and must cope with the network unreliability problem and the energy consumption. In WSN, few routing and clustering protocols take into consideration of these problems. It is a major challenge of the clustering protocols to ensure network survivability through redundancy features. In this paper, we present a short literature review of the existing routing protocols for Wireless Sensor Network and we evaluate the performance of AEEPC, APC-T and APC using the routing protocols AODV.

Abstract :

Network on Chip (NoC) is one of the efficient on-chip communication architecture for System on Chip (SoC) where a large number of computational and storage blocks are integrated on a single chip.NoC has more flexibility and reusability when compared with dedicated wires where number of wires increases dramatically as the number of cores grows.In this project 2X2  and 4X4 mesh topology NoC has to be designed and implemented. The proposed NoC is based on adaptive XY routing algorithm. In Adaptive XY algorithm ,if any neighbouring router becomes faulty,faulty link of the router will be bypassed.The area requirements of the NoC is very high.In order to reduce the area,the input and output buffers of the NoC will be replaced with elastic buffers.Inorder to further improve the performance of the NoC ,an arbiter can be introduced.Arbiter is used when many input ports request the same output port and in such cases a priority will be assigned for input ports when they request the same output port.  The NoC’s performance have to  be evaluated and implemented on Spartan3E  field programmable gate array kit.

Abstract :

Diabetes is a life-threatening issue in modern health care domain. With the use of data mining techniques, diabetes factors and co morbid risk conditions associated with diabetes has found. In order to stifle the evolution of diabetes mellitus, applies distributed association rule mining and summarization techniques to electronic medical records. This helps to discover set of risk factors and co morbid conditions in distributed medical dataset using frequent itemset mining. In general, association rule mining (ARM) generates bulky volume of data sets which need to summarize certain rules over medical record. This encompasses a novel approach to find the common factors which lead to high risks of diabetes and co morbid conditions associated with diabetes. This performs both association rule mining and association rule summarization techniques with improved classification algorithms. Exiting systems aim to apply association rule mining to electronic medical records to discover sets of risk factors and their corresponding subpopulations that represent patients at particularly high risk of developing diabetes. Given the high dimensionality of EMRs (Electronic Medical Records), association rule mining generates a very large set of rules which we need to summarize for easy clinical use. The existing system reviewed four association rule set summarization techniques and conducted a comparative evaluation to provide guidance regarding the diabetes risk prediction.

Abstract :

Smart grid application is the most concerned application in the real world environment which will generate different power readings in different time periods. This need to be gathered and send to the centralized server for further processing. The single node failure in the smart grid system might lead to entire system failure where the aggregation cannot be performed well. This problem is resolved in the existing work by using the fault tolerance based data aggregation technique where the data can be aggregated even if any of the nodes failed in the system. However data integration becomes the greatest issue in the smart grid system where the data forwarded to the centralized server might get changed in case of corruption. This problem is resolved in the existing work by introducing the recoverable scheme in which data can be recovered even in case of corruption also. This is achieved by comparing with the average aggregated value with all the data that are sensed by the sensors.

Abstract :

In recent years, support vector machines (SVMs) have shown good performance in a number of application areas. The existing system is concentrated on the discovery of risk of having pre-diabetes or undiagnosed diabetes and to facilitate people decide whether they should see a physician for further evaluation.  It is also focused on both the noninvasive and metabolic factors, which should require blood sampling and laboratory measurements, such as high density lipoprotein (HDL), and cholesterol (CHOL). However the existing system ahs issue with prediction results by using c4.5, naïve bayes tree and neural network algorithms. To avoid the above mentioned issue we go for proposed system. In proposed scenario, we introduced an efficient algorithm named as Support Vector Machine (SVM) which is utilized to screen diabetes, and an ensemble learning module is added. It turns the “black box” of SVM decisions into comprehensible and transparent rules, and it is also useful for solving difference problem. The proposed system is used to develop an ensemble system for diabetes diagnosis. Specifically, the rules are extracted from the SVM algorithm and it is applied to provide comprehensibility and transparent representation. These rule sets can be regarded as a second opinion for diagnosis and a tool to screen the individuals with undiagnosed diabetes by lay users. From the experimental result, we can conclude that the proposed system is better than the existing scenario in terms of reduction of the incidence of diabetes and its complications.

Abstract :

Introduction: Noise pollution is a health hazard and induces both auditory and non-auditory effects. Extensive levels of noise are associated with a high risk of physiological changes such as hypertension, increased levels of heart beat rate, peripheral vasoconstriction and thus peripheral vascular resistance. Noise can trigger both endocrine and autonomic nervous system responses that in turn affect the cardiovascular system and may be a high risk for the appearance of cardiovascular disease. Aim: This retrospective study provides a comprehensive review of the new evidence linking noise pollution to cardiovascular risk. It considers some fundamental issues concerning noise and its consequences on the cardiovascular system. Method: An extensive review of the International literature was performed through the electronic databases Pubmed, Scopus and Google Scholar and the Association of Greek Academic Libraries Link (Heal-Link), using as key words the following terms: noise pollution, noise exposure, cardiovascular risk, hypertension. Results: Sleep deprivation or fragmentation is usually considered the most severe non-auditory effect of noise pollution, which in turn affects the cardiovascular system. Noise exposure is also associated with hypertension and consequently with other cardiovascular disease, the results from the literature, however, are inconclusive.  Conclusions: Noise pollution has many adverse effects on health and especially on the cardiovascular system. Understanding the harmful effects of noise pollution on cardiovascular health will help us to take all the appropriate measures to prevent or to reduce the possible health risks.

Abstract :

The power loss on distribution transformers can account for a considerable portion of the overall loss. Here in This paper, proposes the method for optimal placement of capacitor banks to the distribution transformers to reduce power loss. The installation of capacitor bank locations are considered at the low voltage side of transformers. The net present value (NPV) analysis is adopted to evaluate cost benefit of the capacitor installation project. First, an explicit formula for direct calculation of power loss of radial distribution systems is derived. Then, the optimal capacitor bank placement is formulated by a Bacterial Foraging Algorithm (BFOA) model maximizing the NPV of the project subject to certain constraints. This model is suitable for being solved by commercial packages and the operational control of capacitor banks to maximize the power loss reduction, we can be simply achieved by local automatic switching according to VAR measurements.

Abstract :

This paper proposes a parallel-LC-resonance type fault current limiter (FCL) that uses a resistor in series with a capacitor. The proposed Fault current limiter is capable of limiting the fault current magnitude near to the pre-fault magnitude of distribution feeder current by placing the mentioned resistor in the structure of the FCL. In this way, the voltage of the point of common coupling does not experience considerable sag during the fault. In addition, the proposed FCL did not use a superconducting inductor which has high construction cost. Analytical analysis for this structure is presented in detail, and simulation results using power system computer-aided design/electromagnetic transients, including dc software are obtained to validate the effectiveness of this structure. Also, an experimental setup is provided to show the accuracy of the analytic analyses and simulation results.

Abstract :

For the purpose of corrosion protection and embellishment, surface coating is the most universally used practice. The applications of nanotechnology in the fields of corrosion protection and surface coatings can significantly improve the adhesion property, stiffness, chemical resistance, weathering resistance and robustness among all other important properties of surface coatings. In this work, nano particles applied surface coatings have been used to protect various types of metals and alloys from corrosion and other degradation. For this purpose, epoxy-zeolite self-cleaning super hydrophobic and antimicrobial corrosion resistant coatings have been used to protect metals and alloys from corrosion. The corrosion protection efficiency has been improved when nanoparticles have been incorporated and dispersed into paint media. Nano coatings have been introduced as smart materials; produced by shrinking the materials at the nano scale level to form a denser product to protect the surfaces with superior approach. Nano particles applied coatings demonstrated a number of advantages such as better surface appearance, chemical resistance, thermal and electrical conductivity, and improved corrosion resistance. Incorporation of nanoparticles in paint formulations improved the corrosion resistance property of antimicrobial zeolite coatings. On the basis of rigorous coating performance test as per ASTM/BIS methods, coating-film passed 3200 hours in salt spray corrosion test, 100% gloss and 100% adhesion; confirmed extraordinary improvement in the fields of corrosion protection and surface coatings.

Abstract :

Metallic glasses-formation rules are mainly based on alloys with one or two principal components. The purpose of this paper is, by summarizing the microstructure characteristics of my and the reported Al-based glasses in terms of their atomic-size difference and enthalpy of mixing. The low GFA of Al- based alloys can be attributed to the relatively low heat of mixing and low relative atomic volume differences of the constituent elements. In addition, the lack of a deep eutectic at high Al-concentrations also contributes to the low GFA. By analyzing the density data of Al-based amorphous alloys, we have demonstrated that the atomic volumes (i.e., the metallic radii) are conserved during alloy formation and the rule of mixture can be applied for the average molar volume. A correlation was found between the crystallization temperatures and hardness values for the Al-based amorphous alloys. Furthermore, a correlation was found between the number of valence electrons and the hardness of Al-based amorphous alloys.  In this way, an electronic rule for the formation of amorphous alloys with high thermal stability and strength could be established: the larger the average total electron number, e/a (or the Pauling valency, VEC), the better the strength and stability.
