Small Scale Pilot Plant Thermal Dryer for Sewage Sludge Dewatering System – A Preliminary Study

Malaysia expected to face serious problem in sewage sludge disposal in the next few years if this problem is not properly manage and well treated. The common way of sludge disposal in Malaysia is to dispose it on the land, by landfill disposal. However, most of the landfill has been closed since reaching it capacity. This product required innovation and advance solution for treatment and disposal since the production of sewage sludge rapidly increasing and the available solution for their disposal is out dated . One of the ideal solution to dispose the sludge is by converting it into useful energy in the form of solid fuel such as pallet and briquette and burn it as a solid fuel to generate power. However, the main problem faced is it contains high moisture content which is more than 90% of moisture content. In order to convert it into useful energy, the moisture content of the sludge need to be reduced into acceptable level which is below 20% . One of the effective methods to remove the moisture content is by using a thermal dryer. The preliminary results from this study found that the thermal dryer produced 63.32kg/h of dried sewage sludge with moisture content less than 20% . The production rate of this dryer shows positive result and with continuous production, this dryer cable to dry tons of wet sewage sludge.
Simulation of a Gas Electron Multiplier Detector for Hard X-Ray Imaging with a Novel Nano Converter

One of the most marvelous applications of GEM is hard X-ray imaging. For increasing the detection efficiency, a photoconverter is usually required. In this work a novel nanostructure photo converter is proposed. Simulation results show that the combination of fast position sensitive gas detector with nanophoto converter can be improved the detection efficiency by one order of magnitude in comparison to the bulk one, which is more benefic for hard X-ray medical imaging applications.
Implementation of Memory Subsystem of Cycle-Accurate Application-Level Simulator of the Elbrus Microprocessors

Performance characteristics of any modern microprocessor largely depend on its memory subsystem. Naturally, the memory subsystem software model is an important component of the cycle-accurate simulator, and its validity and quality have high impact on the overall accuracy of the simulation. In this paper the cycle- accurate application-level simulator of the Elbrus microprocessor family is introduced. The structure of the cycle-accurate simulator is briefly explained. After that the software model of memory subsystem and its integration as a part of the cycle-accurate application-level simulator are described. We evaluate accuracy of the application-level cycle-accurate simulator on the SPEC CPU2006 benchmark and analyze the simulation errors. Finally, a brief comparison of different Elbrus architecture simulators is given.

Research on the Prediction of Drug Sales Based on Levenberg-Marquardt Algorithm

Prediction of drug sales trend is very important for the drug production planning and inventory. The paper studies the BP neural network and presents a kind of method based on reformative neural network to solve the issue of prediction of drug sales. Compare with traditional BP algorithm, the result reveals that this algorithm has structure rationalization and rapid constringency velocity. The experimental results demonstrate that the prediction model based on Levenberg_Marquardt algorithm is good at predicting drug sales.
Refractory Rhinosinusitis

Various factors have been proposed to be related to refractory chronic rhinosinusitis (CRS). Treatment for refractory CRS is challenging for ear, nose, and throat (ENT) surgeons. The aim of the study was to determine the clinical features associated with the severity of CRS that may necessitate revision surgery by eliminating the bias of the surgeon’s technique using standardizing surgical procedures. Sinus wall thickness and blood eosinophilia, which may represent the depth of inflammation in CRS, are associated with the need for revision surgery. We found that, when the thickness of the posterolateral maxillary sinus wall is more than 3.03 mm, there is an increased probability for a need for revision surgery. CRS patients with thickened sinus walls were found to have poorer outcomes. Further research is needed in order to justify this type of surgical procedure for CRS.

Novel NDE techniques in the power generation industry

The thesis presented here comprises the work undertaken for research into novel NDE techniques in the power generation industry. This has been undertaken as part of the Engineering Doctorate Scheme run by the Research Centre for Non-Destructive Evaluation (RCNDE), which aims to bridge the technological gap between university research and industrial application. In this case, the scheme consisted of two projects completed in conjunction with RWE npower looking at current NDE problems in steam turbine and steam-raising plant. The first project was concerned with detecting microstructural transformation in steam turbine blades, which can act as a precursor to failure by environmentally assisted cracking. This project, and indeed, this entire thesis is principally based on electromagnetic testing methods. An eddy current technique for mapping the microstructural phases was produced and validated as far as was achievable; this offered a significant time-saving advantage over the previous method, by reducing inspection time from 5 man days to just 1.5. The technique has novelty in producing a 2-dimensional map of the blade surface which highlights areas where microstructural phases differ. The second project focuses on the detection of microstructural damage associated with material creep life expiry. This forms a review of the current state of technology and highlights potentially useful paths for future research in both established and emerging NDE technologies, including Magnetic Barkhausen Noise testing and laser-generated ultrasound. Both projects have provided tangible benefit to the sponsoring company and have pushed forward research in a number of technological applications.
An empirical study on the impact of critical success factors on the balanced scorecard performance in Korean green supply chain management enterprises

Rapid industrial modernisation and economic reform have been features of the Korean economy since the 1990s, and have brought with it substantial environmental problems. In response to these problems, the Korean government has been developing approaches to promote cleaner production technologies. Green supply chain management (GSCM) is emerging to be an important approach for Korean enterprises to improve performance. The purpose of this study is to examine the impact of GSCM CSFs (critical success factors) on the BSC (balanced scorecard) performance by the structural equation modelling, using empirical results from 249 enterprise respondents involved in national GSCM business in Korea. Planning and implementation was a dominant antecedent factor in this study, followed by collaboration with partners and integration of infrastructure. However, activation of support was a negative impact to the finance performance, raising the costs and burdens. It was found out that there were important implications in the implementation of GSCM.
Electrostatic micromanipulation of bubbles for microreactor applications

A bubble-based chemical reaction/analysis system is proposed that uses electrostatic micromanipulation. Micro/nanoliter-sized bubbles are set in a liquid layer below an electrode array device. The micro bubbles are manipulated smoothly by the electrostatic force generated by the electrode array. A chemical reaction between two gas reagents, exemplified by 2NO+O/sub 2//spl rarr/2NO/sub 2/, has been demonstrated.
Detecting Melanoma Antigen Family A3 Expression in Solid/Non-Solid Human Tumor

Background: MAGEA3 is a member of melanoma antigen family and has been recognized to express in many types of human cancers recently. In spite of the development of cancer vaccine, the prognostic value of MAGEA3 has not been well evaluated, due to the variability of clinical data and lack of clinical trials on the prognostic values.Method: Studies that evaluated MAGEA3 expression with a follow-up for at least 36 months were selected by searching in PubMed, WOS, Cochrane library, Embase. Published data was recorded and calculated into odds ratios (OR) for mortality in three or five years with Mantel-Haenszel random-effect model. Results: 11 studies were selected. The median positive rate was 45%. MAGEA3 always combines with worse survival on three or five years survival. The correlation between MAGEA3 and squamous carcinoma seemed stronger than adenocarcinoma on three-year OS while things got a reverse when it came to five-year OS. Most importantly, we found that all solid tumors originated from endoderm seemed to enjoy a strongest correlation among all the three germ layers.Conclusion: In this meta-analysis, we found that the expression of MAGEA3 can connect with worse outcome, and it probably can be a predictor for patients’ prognosis in clinical practice.
Planar diplexer using composite right-/ left-handed transmission line under balanced condition

A novel high-performance planar diplexer is proposed. The filtering response of a balanced composite right/left-handed transmission line (CRLH-TL) is investigated first. The diplexer is then implemented based on two balanced CRLH-TLs. Simulated results and experimental verifications are provided, and simulation results are found to be consistent with measurement results. This diplexer shows advantages in terms of the low loss, high isolation, easy fabrication and integration with other circuits.
Inside the Mechanics of Network Development: How Competition and Strategy Reorganize European Air Traffic

Air transport forms complex networks that can be measured in order to understand its structural characteristics and functional properties. Recent models for network growth (i.e., preferential attachment, etc.) remain stochastic and do not seek to understand other network-specific mechanisms that may account for their development in a more microscopic way. Air traffic is made up of many constituent airlines that are either privately or publicly owned and that operate their own networks. They follow more or less similar business policies each. The way these airline networks organize among themselves into distinct traffic distributions reveals complex interaction among them, which in turn can be aggregated in larger (macro-) traffic distributions. The author's approach allows for a more deterministic methodology that will assess the impact of airline strategies on the distinct distributions for air traffic, particularly inside Europe. One key question this paper is seeking to answer is whether there are distinct patterns of preferential attachment for given classes of airline networks to distinct types of European Airports. Conclusions about the advancing degree of concentration in this industry and the airline operators that accelerate this process can be drawn.
Day-ahead price forecasting of electricity markets based on local informative vector machine

In a competitive electricity market, short-term electricity price forecasting are very important for market participants. Electricity price is a very complex signal as a result of its non-linearity, non-stationarity and time-variant behaviour. This study presents a new approach to short-term electricity price forecasting. The proposed method is derived by integrating the kernel principal component analysis (KPCA) method with the local informative vector machine (IVM), which can be derived by combining the IVM with the local regression method. IVM is a practical probabilistic alternative to the popular support vector machine. Local prediction makes use of similar historical data patterns in the reconstructed space to train the regression algorithm. In the proposed method, KPCA is used to extract features of the inputs and obtain kernel principal components for constructing the phase space of the time series of the inputs. Then local IVM is employed to solve the price forecasting problem. The proposed method is evaluated using real-world dataset. The results show that the proposed method can improve the price forecasting accuracy and provides a much better prediction performance in comparison with other 12 recently published approaches.
On the Ship Motion Reduction by Anti-Pitching Fins in Head Seas

The ideal aim of the ship motion reduction by anti-pitching fin in waves might be a heaving-less and/or pitching-less state. Equations of motion at this state give conditions to be satisfied by fin's location, area and aspect ratio. These equations mean that wave-exciting force and moment of main hull are cancellated by fin's ones.Calculating such fin's particulars with respect to a container-cargo ship, conclusions are : (1) heaving-less and pitching-less state may be possible by two-pairs of fairly large fin installed at appropriate location. (2) pitching-less or heaving-less state may be obtained by one-pair of fin. The fin area is smaller, the location be nearer F. P. in general. Optimum aspect ratio of the fin, especially for anti-pitching, is very small and lies out of assumption, so that another theoretical approach might be necessary.The experiments in head waves are carried out and confirmed theoretical conclusions. The present results are of a container-cargo ship, there might not be much difference in general tendencies but in details for the other types of ship.
Comments on the paper Equilibrium Selection via Adaptation: Using Genetic Programming to Model Learning in a Coordination, by Chen, Duffy and Yeh

The cited paper uses Genetic Programming (GP) to simulate a well known coordination game, replicating some of the results observed in experiments. This short note suggests that the results presented in the paper cited in the title can be obtained in a much simpler way, due to the action of random actions and selection only. I implemented the same environment as in the original model, replacing the GP originally used with randomly choosing agents. A simple selection mechanism removes least performing agents replacing them with new ones that choose their action randomly. The results obtained do not differ from the ones presented in the original paper. The model used for these notes is distributed as example model in Laboratory for Simulation Development .
Analysis of In-Service Traffic Sign Retroreflectivity and Deterioration Rates in Texas

Roadway traffic signs are a fundamental medium for conveying critical information to the road user. In 2009, the Manual on Uniform Traffic Control Devices (MUTCD) set minimum retroreflectivity requirements for such signs. Developing sign management strategies on the basis of service life is one approach to achieving compliance with minimum MUTCD sign retroreflectivity requirements. Generating deterioration rates and prediction models from a sample of in-service sign measurements is one method for establishing expected service life. In 2009, researchers collected a sample of 859 ASTM D4956 Type III retroreflectivity signs in seven regions of Texas. The objective of this study was to assess the compliance of Type III signs throughout Texas and to generate useful data that would improve sign maintenance practices. The overall sign sample compliance rate was 99%. The observed likelihood of failure was 2% for signs that were between 10 and 12 years old and 8% for signs that were 12 to 15 years old. The linear prediction models revealed differences in deterioration rates between the regions. The differences ranged from −2 to −8 candelas (cd)/lx/m2 per year for white sheeting and −1 to −12 cd/lx/m2 per year for yellow sheeting. Models exhibited poor correlations between predicted and measured data, and the R-squared values ranged from . 10 to . 30. Despite the weak relationships, the models revealed insightful trends and provided a broad perspective on the Texas Department of Transportation's current sign practices. Deterioration rates and prediction models can be valuable components in a comprehensive sign maintenance program, but by themselves they do not ensure compliance with sign retroreflectivity requirements.
The Integrations of Biomaterials and Rapid Prototyping Techniques for Intelligent Manufacturing of Complex Organs

In the human body, an organ is a composite of different tissues in an ordered structural unit to serve a common function [1]. Ordinarily, cells self-assemble into tissues before forming an organ. There are at least three different tissues in a complex organ, such as the liver, heart, and kidney. Currently, complex organ failures are the first cause of mortality in developed countries despite advances in pharmacological, interventional, and surgical therapies [2]. Orthotopic organ transplantation is severely limited by the problems of donor shortage and immune rejections [3]. Extracorporeal support systems perform some specific functions within a limited time period [4]. Cell encapsulation techniques face the problems of capsule loss, low stability, and poor efficiency [5]. Cell sheet technique cannot rescue tissues with in‐ creased thicknesses above 80 μm [6]. Decellularized matrices are hard to be repopulated by multiple cell types [7]. On the other hand, stem cell research has emerged as one of the most high-profile and promising areas of 21st century science [8-10]. Typically, autologous adi‐ pose-derived stem cells (ADSCs) represent one of the most abundant, easily cultured, rapid‐ ly expanded, and multipotent cell source [11]. It has been a long-term goal in this field to manufacture complex organs from biocompatible materials (including non-immune patient derived cells) and computer-aided design (CAD) models in a fast, easy, cheap and automat‐ ic manner.
Design of Video Motion Detect System Based on SOPC

It is very necessary to apply motion detection to video surveillance in order to enhance the performance of system. A new design scheme of video motion detect system based on System On a Programmable Chip is proposed. Two cameras will capture the video data in real-time, and transmitted to DE2_70 development board. After the system which is on a programmable chip based on FPGA processing, the cameras survey whether an illegal personnel is in the range of cameras. The system achieves that two-way video to switch through the switch button. The experimental results show that the SOPC realization of the system design improves the processing speed, and the system also has good flexibility.
Multiobjective optimization for performance-based design of reinforced concrete frames

In order to meet the emerging trend of performance-based design of structural systems, attempts have been made to develop a multiobjective optimization technique that incorporates the performance-based seismic design methodology of concrete building structures. Specifically, the life-cycle cost of a reinforced concrete building frame is minimized subject to multiple levels of seismic performance design criteria. In formulating the total life-cycle cost, the initial material cost can be expressed in terms of the design variables, and the expected damage loss can be stated as a function of seismic performance levels and their associated failure probability by the means of a statistical model. Explicit formulation of design constraints involving inelastic drift response performance caused by pushover loading is expressed with the consideration of the occurrence of reinforced concrete plasticity and the formation of plastic hinges. Due to the fact that the initial material cost and the expected damage loss are conflicting by nature, the life-cycle cost of a building structure can be posed as a multiobjective optimization problem and solved by the e-constraint method to produce a Pareto optimal set, from which the best compromise solution can be selected. The methodology for each Pareto optimal solution is fundamentally based on the Optimality Criteria approach. A ten-story planar framework example is presented to illustrate the effectiveness of the proposed optimal design method.
Advanced and natural interaction system for motion-impaired users

Human-computer interaction is an important area that searches for better and more comfortable systems to promote communication between humans and machines. Vision-based interfaces can offer a more natural and appealing way of communication. Moreover, it can help in the e-accessibility component of the e-inclusion. The aim is to develop a usable system, that is, the end-user must consider the use of this device effective, efficient and satisfactory. The research's main contribution is SINA, a hands-free interface based on computer vision techniques for motion impaired users. This interface does not require the user to use his upper body limbs, as only nose motion is considered. Besides the technical aspect, user's satisfaction when using an interface is a critical issue. The approach that we have adopted is to integrate usability evaluation at relevant points of the software development
Antenna‐beam shaping from offset defects in UC‐EBG cavities

We present a new application of uniplanar compact electromagnetic bandgap (UC‐EBG) structures in antenna‐beam shaping for indoor mobile communications. Such UC‐EBGs are used to construct Fabry–Perot‐type cavities in which the enhanced directivity can be achieved from conventional patch antennas. This paper demonstrates that an antenna beam can be shaped by shifting the defects (patch antennas) from the centre of UC‐PBG cavities. The theoretical predictions are verified by numerical simulations and measurement results, and it appears that antenna‐beam shaping in UC‐EBG cavities can achieve the same radiation patterns as complex planar‐antenna arrays used for improving the quality and strength of sent/received signals in mobile base stations. © 2004 Wiley Periodicals, Inc.
