Title: Comparative study on crushing load of stainless steel tube infilled stub column
Author (s): Alein J. S., Yeturi Pramod Kumar Reddy, Vasugi K. and S. Elavenil
Abstract:

The use of in-filled columns is a new trend in composite construction industry. The bearing capacity is more than the sum of individual load carrying capacity of the stainless steel tube and concrete. In this paper the austenitic stainless steel tube of 304 grade is used. The conventional concrete is replaced by using geopolymer concrete as an infill material. A stainless steel tube of various thickness is used as a major parameter in this experimental investigation. The behavior of infilled stub column and hollow stub column is studied experimentally by applying gradual load along with analytical study using finite element software ANSYS. The design strength of the composite stub column was predicted by carrying out numerical investigation using various international codes. The ultimate load carrying capacity of the infilled stub column was calculated by experimental and analytical work and the results of the same were compared for numerical simulation. The results based on strength parameters were directly proportional to the thickness of the material used.

Title: Development of diesel piezo injector driver using microcontrollers
Author (s): Youngju Lee and Choong Hoon Lee
Abstract:

A diesel piezo injector driver was developed using microcontrollers and MOSFETs. Fuel injection with a common rail injector is possible when controlling the magnitude of the hydraulic pressure acting on the nozzle needle. There are two types of solenoids and piezo-electric components to open and close the hydraulic passages acting on the nozzle needle. A solenoid-type injector is driven by controlling the current waveform supplied to the injector via a peak & hold approach. The solenoid-type injector driver can be implemented with a circuit that switches the driving power with one transistor which has a high current capacity. In contrast, a piezo-type injector is driven by the contraction and expansion of piezoelectric elements that open and close the hydraulic passages to control the movement of the nozzle needle. In order to control the contraction and expansion of the piezoelectric element in a piezo injector, charge and discharge control of the current supplied to the injector is required. For this purpose, a pair-switch circuit capable of charging and discharging the current supplied to the injector has been developed. The driving voltage of the piezo injector was in the range of 100 ~ 140V. High voltage and current switches were used for charging and discharging. Fuel injection at a high common rail pressure was possible with higher driving voltage supplied to the piezo injector. The control signal supplied to the MOSFET (IRF640N) is generated with the output pin or CCP pin of an 8-bit microcontroller PIC16F917. The common rail pressure was controlled by supplying square waves while varying the duty ratio of the control signal. The microcontroller's capture compares PWM (CCP) pins outputs the control signal. When the duty ratio of the PWM square wave supplied to the rail pressure controller is increased, the common rail pressure is decreased.

Author (s): C. Venkata Siva Rama Prasad and T. V. S. Vara Lakshmi
Abstract:

In the recent past bacterial concrete has been emerged as remedial measure of healing cracks in structures like bridges, RCC Buildings, RCC Pipes, Canal Lining, Pavement etc. Crack formation is incredibly common occurrence in concrete structure that permits the water and completely different sort of chemical into the concrete through the cracks and reduces their strength and that additionally have an effect on the reinforcement once it comes contact with water, carbon dioxide and different chemicals. For repairing the cracks occurred within the concrete, it needs regular maintenance and special sort of treatment which can be terribly expensive. So, to solve this problem Henk Jonkers introduced bacterial concrete to repair the cracks occurred in the concrete structures. This research has demonstrated that particular types of microorganisms can really be useful method to repair cracks in the existing concrete structures. In this paper, experimental investigation done to arresting the cracks in the concrete using bacillus subtilis bacteria and calcium lactate. The selection of bacteria depends on its survival in alkaline environment. In this study bacillus subtilis bacteria with calcite lactate is used in different percentages such as 5%, 10%and 15% of cement weight for M20 and M40 grade concrete. An empirical relation between flexural strength and compressive strength is proposed in the form of ft = 0.66 vfck.

Title: A review: The effects of particle properties on solid particle erosion for oil and gas pipelines applications
Author (s): Dinesh Kanesan and Mysara Eissa Mohyaldin
Abstract:

The production of sand along with hydrocarbons has been a major problem faced by the oil and gas industry ever since the discovery of oil and gas. The production of sand from the reservoirs may result in erosion, accumulation, plugging and contamination by sand particles. Sand particle erosion may lead to failure of piping components or equipment, leaks in pipelines, and also hazard to personnel on site. Hence, the prediction of solid particle erosion rate is critical in ensuring the integrity of equipment and the safety of the system. Empirical models are developed by performing experiments to measure erosion rate at different particle properties and flow parameters. Particle properties include particle size, shape and hardness. Any change in these properties will result in a change in the erosion rate. In this review paper, the findings of previous researchers on the effects of particle properties on solid particle erosion rates were identified and reviewed. In addition, the limitations in some of the research done were highlighted to enable researchers to further study on the identified areas. This current work would be beneficial to researchers who are developing empirical models by identifying the key particle properties to be included in their solid particle erosion prediction models.

Title: Estimation of harmonics using adaptive wavelet neural network
Author (s): M. Sujith and S. Padma
Abstract:

Increase in the power electronic devices had leads to the harmonic contamination. Harmonic analysis is done to know about the origin and cause of the harmonics in the power system. The low order harmonics is monitored because these are very dangerous and cause serious power quality issues. Wavelet networks (WNs) is an effective version of nonlinear signal processing techniques in recent years an adaptive wavelet neural network (AWNN) is the most appropriate for prevailing low-order harmonics estimation. Odd-harmonic components of the voltage/current signal are decomposed into the frequency bands by using the above technique. Instead of one complete cycle data for estimating the harmonics the proposed scheme only requires an only half-cycle data point. The back propagation is used for training of the network parameters which is a easy, fast converging and reliable learning algorithm. The experimental signal which is obtained is examined with the projected method. The output result conforms that AWNN technique is effective in estimating the lower order harmonics, inter-harmonics if they are deviated from the fundamental frequency.

Title: Associative coprocessor block based on PLD for different computer systems
Author (s): Martyshkin A. I.
Abstract:

The article considers the possibility of implementing an associative coprocessor block on a modern element base for specialized computer systems. The goal of the article is the development and study of the associative co-processor block on PLD, for specialized computing, for example, multi-processor, systems, performing associative function and data storage functions. The object of research and development of this article is the associative coprocessor based on PLD. The search operation is widely used in different purposes as users and systems. However, this operation is one of the most labor-intensive and requires time-consuming when implemented in the traditional way, when the search data is sequentially read from the machine RAM to the CPU, where they perform the appropriate operation. The paper proposes associative co-processor connected to the PCI bus of a computer system, providing search and comparison of ďmore Ė lessĒ simultaneously in 32 of said pre-loaded in the associative memory. Finally, conclusions have been made. The use of the VHDL language as a universal means of hardware description of integrated circuits provides the flexibility of the project and the ease of debugging the operation of the device. Modeling the associative co-processor was carried out in CAD Web pack ISE of Xilinx company. This allows to evaluate the correct operation of the hardware coprocessor in the composition of computing systems without building the actual layout. Introduction efficiency of the module is assured by the fact that the coprocessor performs a time-consuming operation to search for and compare data and thus relieves the CPU and increases the performance of the computing system as a whole. The results obtained in the article can find application in the search engines for different purposes: servers, databases, search machines used at stations, airports and for fast implementation of the search task operating systems.
