Abstract :

The present study has aimed to identify the transmission channels of the monetary policy on the domestic product and on the general level of prices in Algeria. In order to do so, we have applied the vector autoregressive model. The study has used quarterly data from the period between 1990 and 2010. Results show that when the discount rate is used as a variable that represents the monetary policy, then the interest rate and the exchange rate channels will have a role in transmitting the variations of the monetary policy to the domestic product. When inflation is targeted, the channels of the monetary policy had no significant role in the monetary transmission. When the money market rate is used as a variable that represents the monetary policy, the exchange rate and the credit channels had a significant role in transmitting the effects of the monetary policy to the domestic product and to the general level of prices.

Abstract :

Mechanical faults, stator faults and rotor faults are the major faults of induction motors. Rotor faults constitute about 10% of total faults of induction motors. The main reasons of rotor faults are the broken rotor bars. Many methods have been used to detect broken rotor bars till now. In this paper, a new method is introduced. A squirrel-cage induction motor is modeled by using MATLAB/Simulink. Model takes motor speed as an input and finds the frequency of side-band harmonics of stator current. Then model compares the magnitudes of side-band harmonics with the magnitude of fundamental component and classifies them according to the number of broken rotor bars. At any load and speed, the method can find and classify the broken rotor bars based on the number of broken rotor bars. Experimental results, along with simulation results verifies the effectiveness of the method.

Abstract :

The high – voltage gain DC-DC boost converters are extensively employed in many industry applications, such as photovoltaic systems, fuel cell systems, uninterrupted power supplies, electric vehicles, and high-intensity discharge lamps. In the commonly employed conventional classical booster, the voltage stress of the main switch is equal to the high output voltage; hence, a high-voltage rating switch with high on-resistance should be used, generating high conduction losses. In addition, an extremely high duty cycle will results in large conduction losses on the power device and serious reverse recovery problems. As a result, the conventional boost converter would not be acceptable for realizing high step-up voltage gain along with high efficiency.  In the present work, a novel single-switch high step-up non-isolated DC-DC converter integrating coupled inductor with extended voltage doubler cell and diode–capacitor techniques is proposed. The proposed converter achieves extremely large voltage conversion ratio with appropriate duty cycle and reduction of voltage stress on the power devices

Abstract :

This paper presents a novel design comprising an original use of photovoltaic technologies for utilization of solar energy while satisfying a growing need for a sustainable environment. We suggest using a lighter-than-air helium-filled platform containing embedded thin photovoltaic arrays (PVA) in order to extract electrical power from the incoming solar radiation (insolation). The goal is to develop an efficient, portable, land-area independent, inexpensive and reliable energy source for all. Three concepts are developed: A simple, helium-filled spherical balloon containing a PVA on the outer skin surface; a specialized paraboloidic balloon with a transparent upper part and an opaque lower part containing paraboloid-shaped photovoltaic cells on the inner surface, thus increasing the insolation conversion efficiency; and the same balloon wherein the inner collectors are replaced by flexible thin mirrors, and the upper transparent part contains a PVA at the focus of the inner paraboloid-shaped mirror, thus augmenting the insolation. In both the spherical and paraboloidic configurations, the power output is similar; however, the power-to volume ratio of the paraboloidic design is higher. We present a detailed preliminary design, including a thorough mechanical design as well as an aerodynamic analysis. The mechanical layout consists of three segments: The balloon; an insulated strapping cable system; and a ground segment. The subsequent aerodynamic analysis substantiates the ability of the proposed balloon and strapping cable system to withstand considerable drag and lift forces while maintaining feasible performance.

Abstract :

This development proposes a family of hybrid converter topologies which can supply simultaneous AC  and DC output loads from a single dc input source . These topologies are realized by replacing the controlled switch of single-switch boost converters with a voltage-source-inverter bridge circuit. The resulting hybrid converters require  very lesser number of switches to provide simultaneous AC  and DC outputs with an increased reliability, resulting from its intrinsic shoot-through protection in the inverter period. Such multi-output converters with better power processing density and reliability can be well suited for systems with concurrent dc and ac loads.

Abstract :

Wrapping technology is one of the effective ways of strengthening concrete elements. Several researchers reported the effectiveness of Glass fiber reinforced polymers and carbon fiber reinforced polymers for improving the strength of the concrete elements. Wrapping on three sides is one of the effective methods for strengthening the beams supporting slabs. Scant literature is available on the strength enhancement of “U” wrapped concrete elements subjected to torsional loads. Prediction of torque and twist is reported in literature for wrapping of FRP material. No such calculation is found for ferrocement wrapping materials. In this investigation an attempt is made to quantify the improvement in twist of “U” wrapped rectangular concrete members subjected to torsional loads “U” wraps.  Ferrocement is taken here as wrapping material as it is economic and best suited for developing countries. Beams were cast with different number of mesh layers with different torsional reinforcement. The beams were analyzed by soft computing method MARS. The same has been derived by analytical model using softened truss model of Hsu with modification in material properties. Softening of concrete and ferrocement is taken into account. Ferrocement “U” wrapped beams are found to undergo more twist than un-wrapped beams. The plain “U” wrap beam has a twist of 0.0054 rad/m while under reinforced beam U3N undergoes a twist of 0.155 rad/m. This shows “U” wrapped beam undergoes maximum twist in comparison of plain “U” wrapped beams. The predictions for twist at ultimate torque are in good agreement with experimental test results. Soften truss model better predicts over soft computing.

Tapping operation which refers to production of internal threads forms an integral part of any machine shop and it is intended to provide semi permanent fastening to the components of product so as to lend themselves for repairs and replacements. Though various methods of internal threading are available such as internal threading by milling, grinding or forming but internal threading by metal cutting which employs a tapping tool is indeed the mostly used for products where accuracy forms the base of evaluation. Last few decades have seen the growth of automobile industries and has resulted in development of its allied operations of which tapping is one of the crucial operation performed. The conventional tapping operation which surely involves rotating the tool and feeding past the pre drilled hole to create the contours called as internal threads and this is followed by withdrawal of tapping tool by reversing it with aid of rotational energy. The present review paper attempts to focus the various tapping attachments for diametrical flexibility  being designed and analysed . The tapping tool is subjected mainly to the torque which tends to be the design factor for tapping tool. The operation of tapping includes rotating the tool in clockwise direction and then withdrawing it by reversing which accounts for considerable amount of time and cost of operation. The tapping tool with diametrical flexibility is designed in CAD software and and analysed using FEA technique.

Abstract :

Historical document contain useful information. It gives chance to know about history of individual, family and conventions with old authentic confirmation. Many manuscripts are written on leaves which may contain ancient culture. They have very limited life span. The causes for degradation of document are environment condition and human negligence. Protection of these old documents is required for our future reference. Image processing technology can help to enhance these documents. It allows extracting text information from document. In proposed system Retinex enhancement technique is used. To get better improvement further Gaussian filter is applied. To do extraction of text from document background variational edge thresholding is used. As it is sensitive to edge most of border areas are preserved. The final image is binary image. It is analyzed that the proposed technique produces better results by removing background noise and improves the quality of document.

Abstract :

This study was conducted to determine the fertility potential of potato grown soils in Pasinler Town region of Erzurum city to achive this a total of 42 soil (was performed to determine soil texture, lime content, soil pH, total salt, soil organic matter content ,cation exchange capacity (CEC) and macro and micronutrient concentrations) and leaf samples were collected (macro and micronutrient content)  and analyzed.

The results showed that 21,43 % clay loamy, 16,67% sandy clay loam, 61,90 % clay texture of the study area, respectively. Most of the soil pH measurements in the area fell between 6,47-8,50   notral and slightly alkaline reactions. Soil organic matter content was deficient in all the region’s soils and approximately of the soils were classed as saline soils. Deficiency of total nitrogen, and plant available phosphorous, zinc, boron and manganese, zinc was determined in 10.52 , 9.52, 100, 100, and 23.80 % of the soils, respectively.

The analysis also showed a total soil Nitrogen (N) content (except 10.52%)  and plant available nutrients (Calcium Ca. Magnesium Mg and Potassium. K) concentrations of soil samples in adequate proportions. Plant available nutrients such as Iron (Fe) and Cupper (Cu) were at suffecient levels. Also Lead (Pb). Nicel (Ni) and Cadmium (Cd) were not at toxic levels in plant and soil samples. Plant available nutrient such as Manganes (Mn), Zinc (Zn), Boron (B) was low in soils sampled from Pasinler town agriculture soils. Plant available P content is insufficient in plant leaf samples.

As a result of this. potato plant leaves grown on Pasinler Plain soils recorded insufficient levels of Phosphorus ,boron , manganese and Zinc .The results indicates that growers should make an attempt to conserve and improve the current fertility status of the soils.

Abstract :

Voltage stability challenges of the Nigeria power system which stem from inadequate generation and poor power evacuation capability of the transmission facilities need not be over emphasized.  The major problems confronting Nigeria power network are low voltage violations, high voltage violations and line MVA limits violations. Voltage violations occur at the buses, which suggest that voltage at the bus is less than or greater than the specified value, which may lead to voltage stability problems. This paper therefore evaluated the voltage profiles of the present 28-bus Nigeria power network via continuation power flow techniques. The results show that under normal operating conditions, all the 28-bus voltage profiles were violated as ±5% tolerance of the rated value were exceeded. It also exposed the network’s poor loadability limits as well as low voltage stability indices problem.

Abstract :

Removal of heavy metals from wastewater is difficult and expensive. The use of methods such as reverse osmosis, ion exchange, activated carbon and adsorption is costly. The search of simpler and less expensive method becomes a main research focus. This study aims to adopt a new technique using pomegranate tannin with flocculant to remove heavy metals in urban wastewater .Removal of iron, cooper and zinc is performed. The tannin extracted from the skin of pomegranate is poured in wastewater to be treated .The flocculant is added after 30mn at 12h so that metals are combined with flocks that are removed by filtration. Experiments with synthetics solutions at concentrations between 20mg/l and 80mg/l showed the efficiency of method, proven by obtaining colored flocks. The taking of wastewater sample to add tannin and flocculant showed the difference in the amount of iron, copper, and zinc in wastewater, before and after treatment. Wastewaters between 0,54mg/l and 3,41mg/l of heavy metals are treated. Yields can reached up to 94.72%. At a high temperature with vigorous stirring, treatment can happen very quickly. This technique of wastewater treatment removes the metallic cations to a very low amount. It is a technique that preserves the environment; less expensive, durable and adapt to classical techniques of water treatment by the use of flocculants.

Abstract :

Maintenance, repair and rehabilitation of existing cement concrete structures involve a lot of problem leading to significant expenditure. In the recent past, there has been considerable attention for improving the properties of concrete with respect to strength and durability, especially in aggressive environments.Self-compacting concrete (SCC) appears to be better choice for a strong and durable structure. Suitable addition of mineral admixtures such as Red mud (RM) and Foundry Sand (FS) in concrete improves the strength and durability of concrete due to considerable improvement in the microstructure of concrete composites, especially at the transition zone. Very few studies have been reported on the use of RM and FS for development of Self compacting concrete and also durability characteristics of these mixes have not been reported. In order to make a quantitative assessment of different cement replacement levels with RM and FS on the strength and durability properties for M50 grades of SCC trial mixes and to arrive at the maximum levels of replacement of cement with RM and FS, investigations were taken. Requirement of proper curing is essential otherwise micro cracks will appear on the surface of concrete.

This work reports on the performance of SCC trial mixes having different replacement levels of cement with RM and FS. The strength and durability characteristics of these mixes are compared with the mixes without SF and RHA. Compressive strengths of concrete at7day, 28 days and 90days were obtained by using various replacement of cement with RM and FS.

Abstract :

This paper represent the future possibilities of   work with recycled aggregate, along the combination of cement & Pond Ash. The bricks, metal and wood items are reused in new construction but the concrete and masonry waste which forms more than 50% of CDW are still not recycled in India. Therefore, there is need to recycle these concrete waste which are creating disposal problem in construction industry. These recycled concrete aggregates (RCA) which are cheaply available from construction and demolition sites can be used in highways construction i.e. in base or sub-base layers of pavement. As the finance and funds are major problem in construction of rural roads, RCA can prove to be best alternative for rural roads which is cheap and sustainable option.

There are many advantages that lead to the use of RCA materials as pavement material in bases/sub-bases of roads. The main advantages of using RCA in the construction industry are of sustainable values and environmental issues. The wastes from construction and demolition works are of large volume and increasing over time. To overcome this issue, sustainable construction is one of the strategies to be considered by the construction industry. One way of achieving this is to introduce recycled aggregates from these wastes of construction and demolition works into pavements.
