Selection of Most Promising Substrates for Biogas Production

– Laboratory equipment AMTS-II was used for anaerobic batch regime testing of the methane generating potential of different organic matter: raw sewage sludge from wastewater treatment plant, glycerol from biodiesel production, fish farming residues and their blends. Twenty days were sufficient to indicate proper substrate compositions. The tests performed in this study enableto avoid useless and time consuming stationary experiments and to select promising options. The results of the tests indicate, that the methane generation potentials for the studied matter were the following: 140…230 m 3 /Mg (Mg – mega gram, ton) for raw sludge, 300…310m 3 /Mg for glycerol and 260 m 3 /Mg for fish residues. After these tests continuous anaerobic degradations in laboratory reactors were carried out. The objective was to find out how toenhance biogas productivity of anaerobic reactors which are located by waste water treatment plants and are employed for excess sludge stabilisation. This objective can be achieved by the addition of waste residues: crude glycerol from biodiesel production and residues from fishery. The addition of glycerol in the amount of 2–5% by weight causes the enhancement of methane production of about 250–400%. At the same time, the increase of total solids percentage concentration in the outgoing sludge is ten or more times less. The content of methane in biogas is higher in the case of admixed substrate.
Failing in Agile Projects: With or without an Iteration Manager

The object of this paper is to invigorate discussion around the best and worst practices for Iteration Managers (IM) within Agile Software Development Projects. This paper is a 'tongue in cheek' discussion of the ways to ensure that your Agile Project fails or worse still, fails slowly rather than being terminated. This paper describes the 'smell' that you will get as the project slowly goes bad. By looking at prior mistakes and lessons learnt this paper is designed to guide future IM's. The author approaches the role of IM from a business (non technical) perspective.
New Trends in RTL Verification: Bug Localization, Scan-Chain-Based Methodology, GA-Based Test Generation

- In this paper, New Trends in RTL Verification is introduced, this includes: bug localization, Scan-Chain-Based methodology, and GA-Based test generation. Manual bug localization in Hardware Description Language (HDL) designs is a time-consuming process; therefore, there is an increased demand for automated techniques that can speed-up the bug localization process. In this paper, a code coverage-based method is proposed to rank suspicious code according to its probability of containing bugs which may result in significantly reducing the debugging time by starting with the first candidate bug location. This method is different from formal methods for error localization such as assertion-based methods which are not suitable for large designs as this method is a simulation-based technique and suitable for large designs. Results show that our method can detect errors in large designs up to several thousand lines of RTL code in few minutes with high accuracy compared to time consumed in hours using manual bug localization with success rate of 100%. An online RTL-level scan chain methodology is proposed to reduce debugging time, effort and accelerate IP emulation. Run-time changes of the values of the signals of the IP during execution-time can be done by the proposed scan-chain methodology. A utility tool was developed to help ease this process. Our experiment shows that, the area overhead is neglected compared to the gained performance benefits. But, design requires more compilation time. The main challenge in using constraint random testing (CRT) is that manual analysis for the coverage report is needed to find the untested scenarios and modify the test cases to achieve 100% coverage. We need to replace the manual effort by an automatic method or a tool that will be able to extract the coverage report, identify the untested scenarios, add new constraints, and iterate this process until 100% coverage is attained. In other words, we need an automated technique to automate the feedback from coverage report analysis to test generation process. In this paper, the implementation of this automatic feedback loop is presented. The automatic feedback loop is based on artificial intelligence technique called genetic algorithm (GA). This technique accelerates coverage-driven functional verification and achieves coverage closure rapidly by covering uncovered scenarios in the coverage report.
Impact of political instability on economic growth, exchange rates and unemployment: Malaysian evidence

: According to economists, political instability is harmful for economic development of any Country. This research attempts to test and analyze causal relationship between political instability and economic growth along with unemployment and exchange rate in the context of Malaysia. Malaysia was faced with political instability issues due to the differences and existence of various races. However according to recent studies, it is viewed as a politically stable economy. There are only a few studies carried out investigating the causal relationship between political instability, exchange rate and unemployment. Our main objective of the study is to investigate the impact of political instability on economic growth along with exchange rate and unemployment. This study employs autoregressive distributed lag (ARDL) approach to cointegration proposed by Pesaran et al. (2001). It depends on a time series data over the time of 34 years starting from 1984. Based on the above rigorous methodology, our empirical results tend to suggest that there is a long run relationship between political instability, exchange rate, unemployment and economic growth and that the impact of political instability on economic growth is significant. The findings are in line with the theoretical background and have strong policy implication for countries like Malaysia.
Autocuration: An Implementation of a Continuous Integration System Employed in the Development of AMD’s Next-generation Microprocessor Core

A mechanism for validating each source code change contribution to the version-controlled source code repository is vital in a large microprocessor design project. This mechanism is part of a software development practice known as continuous integration. This paper will describe AMD’s “Autocuration” system: the set of tools comprising the automated continuous integration system used in the development of the verification and Verilog HDL source codes for AMD’s next-generation microprocessor core. To make efficient use of available computer resources, the system has a dynamic process to determine the appropriate subset of regression test suites that need to be run for each source commit to the trunk. It also maintains the latest overall passing version of the microprocessor core as well as the latest passing version of individual unit suites, which provides a convenient way for each sub-team responsible for a particular functional unit of the microprocessor core to choose a version of the trunk that is suitable for running nightly regression tests. The data stored in the system is also a useful source for generating metrics to track the state of the project. The architecture of the system and all its components will be presented in detail along with the supporting flows, problems in the current system, and ideas for further improvement.
The Effect(s) of Essential n-6 Linoleic Acid and n-3 α-Linolenic Acid, and their Fatty Acid Ethanolamides on Food Intake Regulatory Systems in the Brain

We hypothesized that the essential n-3 and n-6 fatty acid ethanolamides (FAEs), but not their parent fatty acids, mediate the suppression of food intake (FI) through the central melanocortin system. Male Wistar rats were injected intraperitoneally ⍺-linolenic acid (ALA), linoleic acid (LA), ⍺-linolenoylethanolamide (ALEA), and linoleoylethanolamide (LEA) after a 12-hour overnight fast. LEA and ALEA, but not ALA or LA suppressed food intake up to 1 hour postinjection. The effect of ALEA on FI negatively correlated with its concentration in plasma without increasing other measured FAEs. In contrast, LEA injection increased its concentration in plasma but also increased OEA, DHEA, and PEA. ALEA but not LEA groups had greater activation of the melanocortin system in the nucleus of solitary tract. In conclusion, ALEA and LEA, but not their parent fatty acids, suppress short-term FI in rats and these effects may be mediated through activation of the central melanocortin system.
Safety and Security Aware Pre-silicon Concurrent Software Development and Verification

- Simultaneously designing and testing both software and SoC designs before silicon is an enticing goal to reduce the time and cost of building embedded devices. The earlier that applications can run on a reliable representation of the SoC, the better. Merging the software and SoC paths before silicon saves time and money and creates a virtuous cycle that gets the embedded product to market faster. This paper describes a new pre-silicon continuum for concurrent SoC and software development and verification for safety and security critical systems, composed of a safety-certified RTOS and advanced C/C++ development tools that continuously support SoC verification from the earliest functional simulator (virtual prototype with Arm Fast Models) through RTL emulation and FPGA prototype stages on the path to first silicon. The continuous convergence brings more safety, security and verified reliability while establishing a more mature software enablement foundation for lead customers and partners at the time of first silicon.
Performance of dual-band AMC antenna for wireless local area network applications

This study focuses on the design, simulation, and fabrication of a coplanar waveguide miniaturised wearable antenna that is fully implemented in textile materials and operable at 2.45/5.8 GHz for wireless local area network applications. This antenna is assumed to be placed near the human body, so that it needs to be miniaturised with excellent performances. To increase the performance of the short-distance textile antenna and to control the specific absorption rate, an artificial magnetic conductor (AMC) is preferred as a reflector plane. The volume of the proposed antenna with AMC is 75 × 50 × 6 mm 3 , the simulation and measurement results are in good agreement and show that the antenna performances perform better results in comparison with the one reported so far in the literature while having a smaller volume. AMC significantly improves the performance of the antenna. The gains of the antenna are 8.2 and 9.95 dBi at 2.45 and 5.8 GHz, respectively (an increase of 3 dB compared with an antenna without AMC).
Time development of Čerenkov radation

Most developments of Cerenkov Radiation are in terms of the Fourier components of the fields and power emitted by a single electron. When many electrons in a compact bunch are emitted from an accelerator, the bunch radiates coherently and at a lower frequency than for a single electron. The theory for the time structure of the fields arising from a charge bunch is developed, and it is shown that the source of the radiation is di/dt. Present detector technology should be able to resolve these fields .
Chronic Kidney Disease and Coronary Artery Disease

Chronic kidney disease (CKD) is a major risk factor for coronary artery disease (CAD). As well as their high prevalence of traditional CAD risk factors, such as diabetes and hypertension, persons with CKD are also exposed to other nontraditional, uremia-related cardiovascular disease risk factors, including in ﬂ ammation, oxidative stress, and abnormal calcium-phosphorus metabolism. CKD and end-stage kidney disease not only increase the risk of CAD, but they also modify its clinical presentation and cardinal symptoms. Management of CAD is complicated in CKD patients, due to their likelihood of comorbid conditions and potential for side effects during interventions. This summary of the Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference on CAD and CKD (including end-stage kidney disease and transplant recipients) seeks to improve understanding of the epidemiology, pathophysiology, diagnosis, and treatment of CAD in CKD and to identify knowledge gaps, areas of controversy, and priorities for research.

Understanding Playfulness An Overview of the Revised Playful Experience (PLEX) Framework

: Users increasingly expect products not only to be useful and efficient, but also to provide enjoyment and experiences. Playfulness is a state of mind of a user, or an approach to an activity. Design that elicits playfulness can make products emotionally appealing to the users and thus provide enjoyable experiences. This paper presents an overview of the revised Playful Experience (PLEX) framework intended to provide an understanding of the different elements that constitute Playful Experience. We summarize the original creation of the PLEX framework and present the validation efforts which led us to revise the framework. Finally, we provide updated definitions of 22 Playful Experience categories. We propose that the PLEX framework can be used by designers as a tool for assisting the design of products that elicit playful attitude and activities from the users.
A dual‐band dual‐pattern frequency‐reconfigurable antenna

The functionality of a dual‐band frequency‐reconfigurable antenna based on a microstrip patch is extended toward independent tuning of its two operational bands. The antenna has distinct monopolar and broadside radiation patterns at its lower and upper bands, respectively, and a previous realization only allowed simultaneous tuning of the two bands. In this paper, a more sophisticated bias scheme with two DC bias voltages and four varactors is introduced to extend the principle toward independent control of the resonance frequencies of the two bands. An antenna prototype has been designed, fabricated, and validated with experiments. The results demonstrate that the antenna achieves independent relative tuning ranges of about 11% at both frequency bands.
Speaker Identification for Biometric Access Control Using Hybrid Features

— This paper presents the application based Neural Network for speaker recognition in a voice authenticated access control system in high security applications. The Neural Network designed for this purpose employs hybrid feature extraction techniques for speaker identification. These features include the time domain as well as frequency domain features and are hence named as hybrid features. Speaker dependent features obtained by Linear Predictive Coding (LPC) and Mel Frequency Cepstrum Coefficients (MFCC) have been used in this work. The hybrid features are used for testing the voice authenticated access control. The performance of different features individually and in combination has been analysed by finding recognition efficiency of speaker identification system. The proposed system uses Feed Forward Neural Network classifier. The results obtained from the hybrid features show the improvement in recognition efficiency. The work has been implemented in MATLAB environment. The experiments have been conducted with English language database and Rajasthani Language.

Managing Multi-Modal Sensor Networks

We propose a unified framework for sensor manage- ment in multi-modal sensor networks, which is inspired by the trading behavior of economic agents in commercial markets. Each sensor node (SN) acts as a seller who wants to sell the data it col- lects, to the sensor network manager (SM) who acts as a buyer. The resources and the data are priced by looking to balance global supply and demand, with the SN required to purchase resources for producing the data, and the SM required to purchase data to accomplish his tasks. We model this interaction as a double sided market, with both consumers and producers, and propose an it- erative double auction mechanism for computing the equilibrium of such a market. We relate the equilibrium point to the solutions of sensor selection (SS), resource allocation (RA), and data fusion (DF) problems, which constitute the sensor management. The pro- posed framework will enable the system to determine the kind and the amount of data that should be produced, and to combine the data that is produced at each SN. To illustrate this framework, we consider the problem of multiple-target tracking as an example. Numerical examples demonstrate the effectiveness of the proposed method, and show that appropriate sensor management will result inanaccurateestimateofthenumberoftargetsinthescene,higher correct identifications of the targets, and a lower mean-squared error in the estimates of their positions and velocities.
A methodology to determine the level of automation to improve the production process and reduce the ergonomics index

Companies are constantly looking for improvements in productivity to increase their competitiveness. The use of automation technologies is a tool that have been proven to be effective to achieve this. There are companies that are not familiar with the process to acquire automation technologies, therefore, they abstain from investments and thereby miss the opportunity to take advantage of it. The present document proposes a methodology to determine the level of automation appropriate for the production process and thus minimize automation and improve production taking in consideration the ergonomics factor.
EFFECT OF ADDING PENICILLIUM ROQUEFORTI SPORES AND ALPHA TOCOPHEROL ON LEAD TOXICITY IN CULTURED NILE TILAPIA ( OREOCHROMIS NILOTICUS )

This study was designed to investigate, evaluate and compare the detoxifying efficiency of Penicillium roqueforti spores and Alpha-Tocopherol dietary supplementation in case of sublethal exposure of Nile tilapia ( Oreochromis niloticus ) to Lead. A total of 100 fish O. niloticus were divided into five equal groups. Group one, untreated control free aquarium water, was fed on basal diet lead acetate (ninety mg/L) was added to the aquarium water to the other four groups. Group (2), lead acetate control positive fed on basal diet, group (3) fed on diet supplemented with (9×10 2 CFU/kg feed) of Penicillium roqueforti , group (4) fed on diet supplemented with Alpha-Tocopherol (300mg/kg feed), group (5) fed on diet supplemented with Penicillium roqueforti spores in addition to Alpha-Tocopherol as (9×10 2 CFU/kg feed and 300mg/kg feed) respectively. Nile tilapia fed at 3% body weight per day for 10 weeks. Results of Pb intoxicated control positive group showed no characteristic clinical signs with presence of some postmortem and histopathological changes. Moreover serum analysis showed significant decreasing in growth hormone (GH), Calcium (Ca), phosphorus, Serum bactericidal activity and Serum lysozyme activity with increasing the mortality rates after challenging with Aeromonas hydrophila . Lead residues in blood, musculatures, gills, kidney and liver indicated that lowest Lead residue was recorded in musculatures but the highest residues were recorded in gills in all groups. Supplementation of Penicillium roqueforti spores and Alpha-Tocopherol improves the adverse effect of Lead in 3 rd , 4 th and 5 th groups. Best detoxification results were in 5 th group. It could be concluded that inclusions of 9×10 2 CFU /kg feed Penicillium roqueforti spores in addition to 300mg/kg feed Alpha-Tocopherol in O.niloticus diets could reduce Lead adverse effects to the favor of fish health, immunity and minimizing the Pb residues specially in fish musculatures.
Navigasi Mobile Robot Nonholonomic menggunakan Fuzzy-Ant Colony System

Navigasi robot merupakan penentuan kedudukan ( position ) dan arah perjalanan baik di medan sebenarnya atau di peta.

PolysaccharidesComplement by Meningococcal Capsular Inhibition of the Classical Pathway of

Almost all invasive Neisseria meningitidis isolates express capsular polysaccharide. Ab is required for complement-dependent killing of meningococci. Although alternative pathway evasion has received considerable attention, little is known about classical pathway (CP) inhibition by meningococci, which forms the basis of this study. We engineered capsulated and unencapsulated isogenic mutant strains of groups A, B, C, W, and Y meningococci to express similar amounts of the same factor H–binding protein (fHbp; a key component of group B meningococcal vaccines) molecule. Despite similar anti-fHbp mAb binding, signif-icantly less C4b was deposited on all ﬁve encapsulated mutants compared with their unencapsulated counterparts ( p < 0.01) when puriﬁed C1 and C4 were used to deposit C4b. Reduced C4b deposition was the result of capsule-mediated inhibition of C1q engagement by Ab. C4b deposition correlated linearly with C1q engagement by anti-fHbp. Whereas B, C, W, and Y capsules limited CP-mediated killing by anti-fHbp, the unencapsulated group A mutant paradoxically was more resistant than its encapsulated counterpart. Strains varied considerably in their susceptibility to anti-fHbp and complement despite similar Ab binding, which may have implications for the activity of fHbp-based vaccines. Capsule also limited C4b deposition by anti–porin A mAbs. Capsule expression decreased binding of an anti-lipooligosaccharide IgM mAb ( ∼ 1.2- to 2-fold reduction in ﬂuorescence). Akin to observations with IgG, capsule also decreased IgM-mediated C4b deposition when IgM binding to the mutant strain pairs was normalized. In conclusion, we show that capsular polysaccharide, a critical meningococcal virulence factor, inhibits the CP of complement. The Journal of and for at in and . Approximately (0.25 (5%) contained g/ml of the anti–factor Bb in a reaction volume of This of mAb and complement was determined following preliminary titration experiments.
