COMPUTATIONAL INVESTIGATION OF A LARGE DUAL FUEL MARINE ENGINE

Continuously increasing environmental demands in conjunction with the planned strong penetration of the LNG, render the use of LNG as an attractive alternative marine fuel. In this framework, the traditional ship propulsion plants based on Diesel engines running with HFO, should be revisited and compared to the more efficient and environmentally friendly propulsion systems that use dual fuel engines. The present study deals with the computational investigation of a marine four-stroke DF engine, in both diesel and DF mode operation. The engine model was set up in GT-Power and used to examine the differences of the performance and emissions parameters of the investigated engine operation at steady state conditions. The engine diesel mode was initially set up and the model was calibrated to adequately represent the engine operation. Subsequently, the engine dual fuel model was set up by considering the injection of two different fuels; methane and pilot diesel fuel. The derived results were analysed for revealing the differences of the engine behaviour at each engine mode. In addition, a method was proposed for facilitating the dual fuel mode heat release analysis. By applying this for the analysis of the derived pressure diagrams, the dual fuel combustion characteristics are analysed and discussed.
GRACE TECHNICAL

There are two approaches to bidirectional programming. One is the get-based method where one writes get and put is automatically derived, and the other is the put-based method where one writes put and get is automatically derived. In this paper, we argue that the put-based method deserves more attention, because a good language for programming put can not only give full control over the behavior of bidirectional transformations, but also enable us to ef-ﬁciently develop various domain-speciﬁc bidirectional languages and use them seamlessly in one framework, which would be non-trivial with the get-based method. We demonstrate how the matching/delta/generic lenses can be implemented in BiGUL, a putback-based bidirectional language.
PRODUCTION AND OPTIMIZATION OF PROTEASE FROM BACILLUS LICHENIFORMIS NCIM 2044

Proteases are proteolytic enzymes which is an essential constituent for all forms of life on earth. Bacteria are most important protease producers with the genus Bacillus being the most prominent source because of their ability to produce large amount of protease having significant proteolytic activity and stability at high pH and temperature. Culture conditions play significant role on growth and production of protease by bacteria. The present work deals with the optimization of culture conditions required for protease production by Bacillus licheniformis (NCIM No.2044) and to compare two nitrogen sources for the maximum production of protease. Maltose was selected as the best carbon source, as it showed a significant maximum production of protease, also peptone and meat were selected as optimum nitrogen source . pH 12 was found to be optimum pH for the production of protease. The optimum incubation time for the maximum production of protease enzyme from Bacillus licheniformis is 72 hrs. Maximum enzyme activity was observed in the presence of Ba 2+ . Among the two nitrogen sources selected maltose with peotone showed the maximum activity in comparision with maltose with meat extract.

Examples are given of damage sensing techniques with a variety of sensors: piezo transducers, fiber optics, strain gages, composite electrical properties, etc. Finally, the paper summarizes the major challenges for composites SHM and identifies research opportunities.
Geochemical Mapping for Mineral Exploration

Geochemical mapping provides a means of visualising spatial variations in the chemical composition of the Earth’s surface. The chemical signature of any specific mineral deposit will reflect the commodities that it contains, and is likely to contrast significantly with that of surrounding rocks. Geochemical maps display and quantify these geochemical contrasts, and are therefore an important line of evidence from which to guide mineral exploration.
EFFECTS OF ANGLE DROOP AND CONTROLLER TYPE IN HYBRID MICROGRID WITH LOAD UNCERTAINTY AND NONLINEARITY

The presented study proposes angle droop control strategy in hybrid microgrid with different types of loads. In this regard, angle droop control strategy is used for generating reference values and appropriate power sharing between distributed generation (DG) units. The proposed control strategy, utilizes current controller beside angle droop controller in discrete time domain to generate appropriate responses in transient conditions for converter base DG units. To improve the performance of control system in reference tracking and transient condition, proportional resonant (PR) controller are used in current controller scheme instead of proportional integral (PI) and the effects of proposed controller is tested on 33 bus IEEE test network. Also a LCL type filter is used to eliminate the harmonics which is produced by the converter. The performance of the proposed control strategy in islanded microgrid with distributed generation units of different types and different load condition is studied in the Digsilent Power factory software environment.
DPDK for COMBO Network Cards

Software framework Data Plane Development Kit provides a standard API for fast packet processing in the user space. The DPDK covers multiple devices and architectures from different vendors. The CESNET association develops the family of COMBO network cards that are able to process traffic up to 100 Gb/s through their proprietary SZE2 interface. This paper describes how the SZE2 library can be used as a backend for the DPDK. This connection enables receiving and transmitting data through the COMBO network cards in a more standard way. The SZE2 library is utilized to create a user space Poll Mode Driver for the DPDK and it has already become part of the DPDK mainline in the version 2.2. 0 (December 2015). The correct positioning of packets in DPDK message buffers and SZE2 buffers is accomplished by copying data between buffer memories. The performance benchmarks has shown that the COMBO-100G network card can receive and transmit over 140 millions of 64 B long Ethernet frames per second unidirectionally and a single port can handle up to 134 millions of 64 B long frames per second in the bidirectional traffic using multiple CPU cores.
GENETIC DIVERSITY AND BOTTLENECK ANALYSIS OF UMBLACHERY CATTLE BY MICROSATELLITE MARKERS

Assessment of genetic variability in Umblachery breed of cattle in Tamilnadu, South India was carried out using eight bovine microsatellite markers. The mean number of allele was 10.25±1.11 per locus with a range of 6 to 15 and the allele size ranged from 95 to 382 BP. The frequency distribution of alleles in the breed was from 0.0556 to 0.2222. The estimated Heterozygosity was 1.0000 and the mean expected Heterozygosity was 0.9283±0.1060. The overall mean within population inbreeding estimate (FIS) value (0.1465±0.0197) indicated excess of heterozygotes in the population. In addition, higher Shannon Index value indicated the higher amount of variation in the population and there is more scope for conservation. Mode shift analysis revealed a normal Lshaped curve indicating that Umblachery population is nonbottlenecked. It is clear that the population has not undergone any reduction in the effective population size and remained at mutation drift equilibrium. Results obtained from this study will help to formulate conservation strategies for Umblachery cattle.

The population of this study are all companies listed in JII period 2014-2016. The sampling method used in this research is purposive sampling method. The result of research shows that the most disclosure on the six ISR index criteria conducted by 21 companies listing in JII is environmental criteria. This proves that there is an awareness of the environmental social responsibility of companies listing in JII. Overall, the average disclosure of the ISR index on 21 JII firms has not been good, only 47.80%. This indicates that there are still many ISR index items that have not been fully disclosed. The results also show a tendency to increase the ISR index. This condition proves the increase of corporate awareness of the obligation of social responsibility according to sharia. This condition proves the increase of corporate awareness of the obligation of social responsibility according to sharia.
Synthesis of Mathematical Models for Measuring Signals

Signals play a key role in instrumentation and are an essential part of measurements. There is a wide variety of signals. First of all, these are signals for measurement of physical quantities: pressures, temperatures, voltages, currents, etc. These signals depend on a type of physical quantity and measurement conditions, and inevitably change with them. For this reason they are known only with a certain degree of probability. In addition, a lot of measurement control signals, signals for display of measured values, etc. are used in measuring means. The so called reference or standard signals play a special role in instrumentation. Their basic parameters and waveform must be set with high precision since they have a small degree of uncertainty, i.e. high accuracy. They are used to have a desired effect on measured objects as ‘‘stimuli’’ or reference forces. Special measuring instruments (signal generators, sources and calibrators, which have been discussed in Chap. 1) are developed and produced for reproduction of these signals. Such devices can generate a variety of standard signals, including sine wave, square, triangle, and pulse ones. Their parameters and characteristics are well known. Figure 2.1 below shows their graphic presentations and mathematical description. When we discuss sine wave generators, we usually idealize a waveform of their output voltage, assuming that it is described by the sine function of time y1(t) = ym sin [(2p/T) (t t0)] with parameters ym, t0 and T, and has only one harmonic in its spectrum. The sine function serves as an idealized model of voltages at the output of low-frequency and high-frequency signal generators, including ones of G3 and G4 groups (Russian classification). It is characterized by the known relationships between peak, average rectified (AVG) and root-mean-square (RMS) values.

Meta-analysis on Instructional Methods Employed and Challenges at Technical Colleges in Nigeria

Article history: Received 23 June 2018 Received in revised form 18 July 2018 Accepted 21 July 2018 Available online 24 July 2018 Technical Vocational Education and Training (TVET) in Nigeria is designed to produce competent craftsmen and technician for different sectors of the economy, therefore, they are expected to be enterprising and self-reliant. However, the development of skills for the training of such personnel have not been adequately successful as a result of numerous challenges. The aim of this review therefore, is to synthesize the available evidences in the literatures about instructional methods employed for the acquisition of skills and the challenges of effective instructional delivery at technical Colleges in Nigeria. The study adopted a systematic review approach to search for relevant literatures. TVET, instructional methods, challenges of instructional delivery, Technical Colleges were some of the key words used to select the relevant literatures from data web-based providers such as: Science Direct, Scopus, Google Scholar, Springer link and Wiley Online Library. The result of this study revealed that the appropriate instructional methods for the adequate acquisition of skills are rarely employed at the Technical Colleges. It was also revealed that there are numerous challenges militating against effective instructional delivery, ranging from inadequate infrastructural facilities, dearth of qualified technical teachers, inadequate instructional facilities/materials, poor funding, in appropriate instructional methods employed, and poor remuneration among others. It is therefore recommended that government should adequately fund Technical Colleges; avail opportunities for technical teachers to update their pedagogical skills through in-service training, conferences and workshops.

ASHOK D. MANKANI et.al DESIGN AND DEVELOPMENT OF 500 kV, 100 mA DC HIGH VOLTAGE POWER SUPPLY FOR PARTICLE ACCELERATORS AT IPR

At IPR Neutral Beam Injection (NBI) facility to heat the plasma and drive the plasma current in Tokamak has been built by accelerating the positive / negative ion beam of energy/power around 100 keV/ 5 MW. Under the current R&D plan the projection is to develop the technology for future Mega Volt range DC Power Source facility to accelerate ion beam of energy to the tune of 1 MeV and power of the order of few MW. To meet this objective a compact 500 kV, 100 mA DC upgradable to 1000 kV Power supply is being designed and developed as a first step. This power supply shall not only serve as test facility for future larger systems but also be used for several other applications within IPR related to particle accelerator. The 500 kV, 100 mA, 50 kW DC Regulated High Voltage Power Supply (500 kV-RHVPS) for particle accelerator is being designed using a symmetrical Cockcroft-Walton Voltage Multiplier (CW-VM) topology owing to its design simplicity and economical construction. This paper will present the design and simulation results of 500 kV-RHVPS modelled in MATLAB Simscape toolbox. The paper will explain the optimization / sensitivity study performed in selecting and sizing of CW-VM, High Frequency Power Source (HFPS), and High Voltage High Freqency Step-up Transformer (HVHF-Tr); the primary components of 500 kV-RHVPS taking into account the possible operational difficulties and future expansion. Both steady state and transient study results will be explained. This paper will briefly cover the engineering assembly design aspects of voltage multiplier unit in general and of a 250 kV prototype voltage multiplier developed.
Discovering New Cyber Protection Approaches from a Security Professional Prospective

Cybersecurity has become a very hot topic due to high profile breaches that occurred in the past years. Despite the implementation of current known pre-emptive methods such as intrusion detection systems, anti-viruses, and the use of firewalls, hackers still find sophisticated means to steal data or impair an organization by targeting their assets. It is important that security professionals need to “think outside the box” and use new tools and techniques to mitigate threats beyond current known detections and prevention technologies. It is imperative that our infrastructure and assets are impermeable from domestic and foreign attackers. Our best line of defense is the detection of any threats or vulnerability to prevent or minimize damages of our assets from domestic and foreign attackers.
Neutral-Axis Position Based Damage Detection of Bridge Deck Using Strain Measurement : Numerical and Experimental Verifications

This paper provides numerical and experimental studies on using the neutral-axis position as a damage index for bridge deck condition assessment. A beam-like deck model subjected to moving bogies is fabricated with crack damage of different extents incurred on a designated cross-section. Making use of a Kalman filter (KF) estimator which is specifically formulated to estimate the neutral-axis position from trafficinduced strain responses, numerical simulations and experiments of the deck model are conducted to verify the sensitivity of the neutral-axis position based damage detection technique to crack damage and the capability of this technique for locating damage. The robustness of the KF estimator is examined under different boundary conditions and under static and moving loads. Both the numerical and experimental results show that the neutral-axis position is highly sensitive to local damage on deck sections and can as well serve as an indicator of damage location when strain sensors are densely instrumented.
Information Extraction from Loosely Structured Text

We are experiencing a data explosion. There is an undoubtedly increasing amount of data published every day on the internet. Scientific articles, journal papers, books, images, movies, music, tweets, statuses and a whole lot more. With this data explosion, new problems arise. Where and how to store these data and how to efficiently search for relevant data? This work should provide a semi-automatic solution to extract relevant data from medicine information sheets. These data should serve as a source data for search engine in the future. Information sheets are stored as semi-structured documents on the website of National institute of Medicine control of Slovak republic. We propose a semi-automatic method, which is able to extract active substances and basic information about symptoms, which suggest usage of specific medicine. Our method have some features of supervised and some features of unsupervised information extraction. Our solution was experimentally evaluated and achieved ∼ 70% accuracy. However, we are focusing on a subset of all relevant information included in these documents. Our solution is inspired by previous unsupervised information extraction, but we have implemented a novel method which includes transferring natural language into intermediate representation with help of Slovak national corpus[1] and information extraction from this representation based on manually created rules.
