    • Abstract: The paper presents a method of the original type in order to determine the effectiveness of a mechanism camshaft and adept. The originality of this method consists of eliminating the friction. In this research analyzes the four types of side camshaft: 1. Camshaft rotary switch and the motherboard translated adept; 2. The mechanism with the camshaft rotary switch and openness to be translated with roll; The 3. The camshaft rotary switch and the rocking chair adept with roll; The 4. The camshaft rotary switch and the rocking chair adept. For any mechanism with the camshaft and the follower is uses a different method to determine the most efficient design. We take into account the mechanism (the timing end) cam, which is the second of the mechanism in internal combustion engines. Optimization of this mechanism (timing end), can improve the functionality of the engine and may increase the comfort of the vehicle too.
  • Gears-Part I

    • Abstract: The gears are today the most widespread and most frequently used mechanical transmissions, all over the world. They must be the factory on an industrial scale, everywhere and have a variety of uses, being extremely important for both the heavy machines of industrial buildings, as well as for domestic appliances, electronics, etc. meet the excessive size normal, big or even huge (used from ships, heavy machines or in energy), but also for the tools watches, or for devices of sizes micro. The work of front wishes to make an overview of the tools and then an introduction to the study of their general and a study customized for gears with fixed. The methods listed for the gears with fixed, can then be customized and used and the gears Planetary Drive (with axis elements). The work of the front and the original components, very much, such as: Geometry, forces, velocities, powers, outputs (gears), which form part of the actual dynamics of the mechanisms and also the most important criterion in respect of the performance of a mechanism.

It analyzes the influence of certain parameters which affects the efficiency of the gearbox. Also an original method for the determination of the yield of the drive shafts oriented on the basis of the ratio of contact is presented the brief.

  • A Dynamic Model for Gears

    • Abstract: Nearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in contact (or more pairs of teeth in contact). It's not seen the physiology of the mechanism itself with toothed gears. In this study we do not only account for the impact of teeth (collisions between teeth) but we also consider all the principal dynamic events that are occurring in top gear plane. This article will present an original model that explores the dynamic events originated and taking place in the plane geared couple of the parallel axes geared transmissions. The first measure to be taken for the protection of the environment of pollution of the over a billion motor vehicles with heat engines already in circulation, is to improve the motors and their drives.
  • Fluid-Solid Coupling Analysis on Evolution of In-Situ Stress Field by
           Water Injection in Oilfield

    • Abstract: Water injection in oilfield may break initial balance of reservoir and lead to re-distribute of stress and deformation of strata. For further research of the evolution characteristics of in-situ field by water injection, the influence on reservoir by water injection was analyzed and different variables were set to study the effects of depth, injection-withdraw ratio and elastic modulus on strain and stress of strata based on fluid-solid coupling theory. Research shows that: As the water injection, the formation pressure around injection well is greater than that of the production well and the effective stress around injection well is less than that of production well. The deeper the formation is, the smaller the normal strain and vertical displacement are. Besides, the largest shear strain is on the top of reservoir, while the smallest is in central reservoir and different injection-withdraw ratios have significant influence on formation pressure. Elastic modulus mainly influences the deformation of the formation and deformation size is negatively related to the elastic modulus. This study provides a reference for casing damage under the effect of water injection.
  • Prediction of Residual Axial Load Carrying Capacity of Reinforced Concrete
           (RC) Columns Subjected to Extreme Dynamic Loads

    • Abstract: The evaluation of residual axial load carrying capacity of Reinforced Concrete (RC) columns to explosion load is significant for protection of buildings. The few investigations conducted on residual axial load carrying capacity of RC columns when subjected to blast loads. Therefore, the overall aim of this research is to generate equations on the blast capacity of axially and uniaxial loaded columns. In this study, an advanced nonlinear model is developed to study the residual axial load carrying capacity (Presidual) of RC columns to explosion loads using Arbitary Lagrangian Eulerian (ALE) finite element technique in LS-DYNA 971. The ALE model represents the actual blast incident scenario and is validated with experimental study reported in the previous research. In order to derive the Presidual empirical equations, intensive parametric studies are carried out to investigate the effects of column depth (d), longitudinal reinforcement ratio (ρ), transverse reinforcement ratio (ρs), yield stress of longitudinal steel (fy), yield stress of transverse steel (fyt), column height (H), column width (w) and concrete strength (fc) on the residual axial capacity of RC columns. Based on numerical simulation data, nine empirical relations are suggested to predict residual axial capacity of RC columns. The validated equations can be used for quick assessment of existing RC columns when blast loading is required to be considered especially to evaluate the blast resistant capacity of a critical building such as military buildings, government assets and etc.
  • Modelling and Assessment of Effect of Operation Parameters on Gas Turbine
           Power Plant Performance using First and Second Laws of Thermodynamics

    • Abstract: In this study, modelling of gas turbine engine performance is carried out using thermodynamics relations. The model reveals that the influence of operation parameters such as compression ratio, turbine inlet temperature and ambient temperature has significant effect on the performance of gas turbine engine. Energy and exergy analyses were conducted to evaluate the performance of the selected power plant and to assess the effect of operation parameters on energy loss and exergy destruction in the plant. Energy analysis shows that the turbine has the highest proportion of energy loss (31.98%) in the plant. The exergy analysis results reveal that the combustion chamber is the most exergy destructive component compared to other cycle components. Thermal efficiency of the plant is as low as 36.68% while the total efficiency defect and overall exergetic efficiency of the power plant are 40.46 and 19.06%, respectively.
  • Forces at Internal Combustion Engines

    • Abstract: The paper presents an algorithm to set the parameters of the dynamics of the classic mechanism the main of internal combustion. It shows the distribution of the forces (on the main mechanism of the engine) on engines with internal combustion. Dynamic, the gears can be distributed in the same way as forces. Practically, in the dynamic regimes, the velocities have the same synchronization as forces. The method shall be applied separately for two distinct situations: When the engine is working on a compressor and in the system of the motor. For the two individual cases, two independent formulae are obtained for the dynamic cinematic forces (gearbox). The calculations shall be made for an engine with a single cylinder. The change of speed in the dynamics feels like a variation of the angular speed of the engine. It is more difficult to be taken into account (theoretically) effect on engine with several cylinders.
  • Inverse Kinematics at the Anthropomorphic Robots, by a Trigonometric

    • Abstract: A robot is a machine especially programmable one through a computer capable of performing a complex series of actions in the automatic mode. Robots may be guided by a control device or external control may be incorporated in the inside. Robots can be built to take human form, but most robots are machines designed to perform a task without taking into account the manner in which it looks. The branch of the technology which is concerned with the design, construction, operation and application of robots, as well as other information systems for their control, the feedback of the touch screen and processing information is quite robotic. These technologies do with automatic machine, which may take the place of the people in hazardous environments or manufacturing processes, or looks like people in appearance, behavior and/or cognitive. Many of the robots of today are inspired by nature which contributes to the field of robotics bio-inspired by it. These robots have created a new branch of robotic (robotic soft). From the time of the ancient civilization there have been many accounts of devices user-configurable automatic and even similar to automatic and people, intended primarily as entertainment. As the mechanical techniques developed by the era of industrial, there were several practical applications, such as automatic machine, remote control and wireless remote control included. Anthropomorphic robots have in their component a plane structure 2R, which is a basic structure. In the reverse (inverse) kinematic, are known the kinematic parameters xM and yM, which represents the co-ordinates of scaling point M (endeffector M) and must be determined by analytical calculation the parameters φ20 and φ30. First, it determines the intermediary parameters, d and φ with relations (1). For the purpose of determining angles can be used various methods (trigonometric, geometric, etc.), of which will be presented below one of them (as the most representative): A trigonometric method.
  • Investigating the Water Sealing Capability of Polymer Concrete

    • Abstract: The concrete water sealing capability improved substantially by using superabsorbent polymer as admixture in the concrete mix design. Researchers tried almost every conceivable material to be mixed in concrete to alter some of its properties. In this research, superabsorbent polymer is used as an admixture to improve its water tightness properties especially in concrete tanks, aeration basins and retaining structures. The concrete tries to seal the leak by blocking the water path by semi-solid gels. This gel is the product of the interaction of the superabsorbent polymer with water. This self-sealing property of concrete can also be used in any tank or container that holds and retains any kind of liquid. The super absorbent polymer absorbs water at a rate of 300 to 500 times its own weight, in a process transforming the polymer dry powered into gel. Mixing super absorbent polymer with concrete not only improves its water tightness capability, but also provides the concrete with internal curing moisture it needs to improve its strength. This property is very useful in cases where curing of concrete is difficult. The fresh concrete plasticity and consistency change as well. This property is yet to be further explored. Several samples have been prepared to study the effect of the superabsorbent polymer on the concrete strength and on the concrete capability to block the water flow. Concrete cubes, concrete beams and concrete tension samples were prepared to study the concrete strength of concrete mixed with superabsorbent polymer. Also concrete short cylindrical samples were prepared to study the concrete ability to block the water flow. These cylindrical samples were intentionally broken into two approximately equal pieces to create an induced crack. The artificially cracked samples are then subjected to water pressure to study the concrete ability to stop the water flow though the induced concrete crack. Two kinds of water pressure are used in this research; the constant head and the falling head. Samples of different amount of superabsorbent polymer were prepared to study the effect of the increase of the superabsorbent polymer on the concrete strength and on the concrete water tightness capability.
  • Integrations of Seismic Data, Petro-physical Evaluation and Reserve
           Estimation in Fimkassar Oil Field of Eastern Potwar, Pakistan

    • Abstract: In upper Indus basin Potwar plateau is a successful exploration area for hydrocarbon. The study area is consisting of Fimkassar oil field and research data is obtained from Land Mark Resources with the special permission of Director General of Petroleum Concession Ministry of petroleum and natural resources Islamabad. The study area consists of well#1 and #2 and seismic lines 97-CP-07, 782-CW-23, 782-CW-25, 884-FMK-101, 884-FMK-102, of the Fimkassar oil field. The 2D seismic study is very essential for interpretation of the subsurface structure clarity in the study area and occurrence of hydrocarbon in deeper horizon of sedimentary basin. The interpretation will be carried out to confirm the reservoir characteristic of the Chorgali Formation to delineate promising location for test drilling into Chorgali Formation. The methodology adopted to achieve the reserves estimation includes the measurements for the shale volume by using Gamma Ray Log, Porosity by density and Neutron Log, Resistivity of water by using SP method, Saturation of water in the zone of reservoir and Hydrocarbon saturation using Archie equation. Time structure maps of the reflectors will be produced using two-way time of the reflectors. Time structure map is converted into depth contour map and get area for reserve estimation. Applying the volumetric method to calculate reserve in Fimkassar area.
  • Study on Danger Index for Ship’s Tanker

    • Abstract: Navigational safety is an important factor for the ship navigation. In this research, the study area is the Malacca Strait. The Malacca Straits has a high level of danger. The navigator should be careful when passing through the strait. Based on the survey, about 85% of the navigator was worried when passing through the area of Straits. Automatic Identification System (AIS) data investigation was conducted on August 2012. Tanker passes through the Malacca Strait about 45% per day. This study focused on the analysis of danger index in Tanker. Results from this study can be used as input to all stakeholders to improve safety while Tanker passes through the Malacca Strait. Scenario for establishing danger Index is taken from the AIS data which is installed in the UTM Malaysia. In detail, danger index was calculated using Analytic Hierarchy Process (AHP) combining with the Automatic Identification System (AIS) data and Geographic Information System (GIS).
  • Block-Matching Twitter Data for Traffic Event Location

    • Abstract: We used a block-matching approach that is data-driven and relies mostly on patterns of tagged speech in Twitter streams as a way to identify events in road traffic. Events are useful because their location may identify the status of road segments, especially when cross-street data are available. Basing a system on patterns that are not pre-defined has the advantage of flexibility for a variety of scenarios.
  • Characterization and Evaluation of Charcoal Briquettes Using Banana Peel
           and Banana Bunch Waste for Household Heating

    • Abstract: The charcoal briquettes from banana peel and banana bunch wastes from dried banana industry for household heating were characterized and evaluated. A 200 L pyrolyzer was used for charcoal and wood vinegar production at 350° pyrolysis temperature. The percent yield of charcoal and wood vinegar were determined. The effects of clay binder (0-15% w/w) on the properties of charcoal briquettes such as ash content, hardness, combustion calorific value, emissions data, burn time and combustion efficiency were evaluated. It was found that the percent yields of charcoal and wood vinegar from pyrolysis of banana peel and banana bunch are 57%, 7.53% and 58.6%, 6.76%, respectively. The banana bunch charcoal retained some functional groups to a higher degree than the banana peel charcoal. These include -OH, C = O, C = C, C-H and C-C groups. The porous shapes of banana peel charcoal and banana bunch charcoal are honeycomb and tube structure, respectively. The calorific value of both charcoal briquettes decreased with increasing ratios of clay and ash content. The values range from 5,115.51 to 6,396.66 cal g-1. The hardness obtained with 5% clay binder is 23.31 kg and 25.90 kg for banana peel charcoal briquette and banana bunch charcoal briquette, respectively. Both charcoal briquettes containing 5% clay are smokeless during combustion and result in red-brown ash after combustion. The dust and total CO emissions of banana peel charcoal briquette and banana bunch charcoal briquette during combustion are 15.38 µg m-3 and 3463 ppm and 11.97 µg m-3 and 1568 ppm, respectively. The maximum temperatures of water are 88 and 84° and times needed to reach the maximum temperatures were 36 and 48 min for banana peel charcoal briquette and banana bunch charcoal briquette combustion, respectively. The maximum burning times and combustion efficiencies are 114 min and 9.10% and 92 min and 8.38% for banana peel charcoal briquette and banana bunch charcoal briquette, respectively.
  • A Review on Cognitive Radio for Next Generation Cellular Network and its

    • Abstract: Cognitive Radio (CR) is considered an intelligent technology. It improves the utilization of the radio spectrum. The increasing number of new devices has resulted in growing congestion of the ISM bands. FCC issued an order only permitting unlicensed users (secondary users) to operate in white space without interfering with licensed users (primary users). Cognitive Radio Networks (CRNs) provides a solution to the problem of additional spectrum requirements by utilizing the spectrum more efficiently. CR is able to sense the spectrum and share the spectrum with unlicensed users. There are number of popular spectrum sensing techniques in CR such as cyclostationary feature detection, energy detection and matched filter detection, which capture the best available spectrum. They use a spectrum dynamically in wireless communication network. A CR with multicarrier technique (OFDM and FBMC) are the next generation of advanced cellular network, which would provide better spectrum utilization and therefore have greater capacity. In this study we have described and reviewed CR technology and its numerous features that may play a very essential role in the field of next generation wireless communication networks.
  • Internet-Based Teleoperation of Carts Considering Effects of Time Delay
           via Continuous Pole Placement

    • Abstract: A new control design for teleoperation considering time delay is presented. Unlike existing methods for communication delays, the design presented here identifies and continuously moves the rightmost eigenvalues to desired positions. Signal transmission through the Internet using protocols (e.g., UDP) introduces time delays into the system. The time delays cause instability as the system is forced to make use of past information rather than the present in determining the output one agent sends to another agent.

  • Integration of Human Factor in Design Ergonomics: Example of a High Speed
           Train Cabin Design

    • Abstract: The development of new technologies and technical progress has accelerated man/machine substitution. Work is disappearing in its human form. This technical progress has not avoided certain catastrophes occurring. These major disasters, both for man and for the environment, took place where reliability was at its highest level. The responsibility of the operator, of the human, the weak point in these systems, is of course quickly pointed out. Human error is thus incriminated. Of course, we do not speak of the accidents that have been avoided because of the intelligence of the operators. For us, the "key of success" of technical progress lies primarily in the adequacy between the performance of the new system, of the new product, etc and those who have to control it. Systems, products, etc, should not be reduced to their technical characteristics alone; they also have to integrate the human dimension. Ergonomics, although not being the only discipline concerned by the necessary change, can contribute greatly. In this context this paper presents an example of the contribution of ergonomics to a design project, where the ergonomist placed man at the centre of the design process. This project concerns the design of the driver's cab of the future TGV (high speed train). The approach requires a detailed analysis of the work activity, namely driving, which has both directed the design process and promoted the co-operation and collaboration between those involved in the design.
  • Yield at Thermal Engines Internal Combustion

    • Abstract: The paper presents an algorithm to set the parameters of the dynamics of the classic mechanism the main of internal combustion. It shows the distribution of the forces (on the main mechanism of the engine) on engines with internal combustion. With these strong points and together with speeds of kinematic couplings shall be determined when the output of the engine heat shield. The method shall be applied separately for two distinct situations: When the engine is working on a compressor and in the system of the engine. For the two individual cases, two independent formulae are obtained for the efficiency of the engine. With these relations is then calculated with respect to the mechanical efficiency of the engine heat shield Otto, in four-stroke, for two-stroke engines and 4 stroke V. the final yield of the engine is obtained taking into account and thermal efficiency given by the Cycle Carnot program.
  • Velocities and Accelerations at the 3R Mechatronic Systems

    • Abstract: This article presents an original method to determine the speeds and accelerations to structures MP R-3 The structure of the 3R (space) are known (required) rotation speeds of the triggers and must be determined speeds and accelerations of the endeffector M. Starting from the positions of direct kinematic system MP R-3deriving these system of relations in depending on the time, once and then a second time (the second derivation) is first obtains the speeds of the system and for the second time the accelerations endeffector point M. System on which must be resolved has three equations and three independent parameters to determine. Constructive basis is represented by a robot with three degrees of freedom (a robot with three axis of rotation). In the case where a study (analysis) a robot anthropomorphic with three axis of rotation (which represents the main movements, it is absolutely necessary), already has a system of the basis on which it can add other movements (secondary,). All calculations have been arranged and in the form of the array.
  • Understanding Hybrid Additive Manufacturing of Functional Devices

    • Abstract: The fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser systems. A multi-axis robot was employed to deposit slurries and colloids of conductive materials on different substrates. Fine deposition of the slurries was achieved by tuning the process parameters such as deposition line speed, extrusion pressure, curing temperature, Z-height, laser beam spot, material type and laser intensity. Precise deposition of the medium viscous colloidal liquids was achieved by pico jet unit. Sintering of the micro/nano particles was achieved using a fiber optic laser system and micro wave furnace. The conductance of the deposited electrical trace varied based on the material type and trace cross-section area. This research lays the foundation to build a three-dimensional hierarchy of electronic components. By embedding components at various depths and orientations complex electronic circuitry with versatile material compositions and design flexibility can be fabricated in situ.
  • Experimental Study of Composite Beams Made of Steel Tubes Filled with
           Concrete under the Confinement Effect of U-Links and Stud-Plate

    • Abstract: Concrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of the letter U welded internally in a steel tube at the compression concrete zone. These tubes provide confinement effect similar to the stirrups used in reinforced concrete beams. The stud-plate element used in this study is made of steel bar welded to a horizontal plate at one of its end, while the other end is welded to the top of the steel tube at the compression zone from the inside of the tube. The main function of these two elements is to provide the concrete in the compression zone with confinement stresses. The composite beam is tested in bending under single load at the mid-span. The effect of the new confinement system is studied and compared with concrete filled tube without any confinement element. The failure mechanism is also a focus of this research along with the deflection at the mid-span of the beam. The effect of the new confinement system on the structural behavior of the composite beam is presented.
  • Development of a Dashboard for a Local Food Bank

    • Abstract: Hunger relief is one of the major needs during humanitarian emergencies. It presents significant challenges to aid organizations trying to manage data, information and knowledge about the situation or event. Food banks receive donations from a variety of sources to meet their demand. The distribution of donated food to meet the unmet hunger needs is a critical issue faced by the food banks across the nation. This paper presents a methodology to apply interactive dashboards to a food bank's decision making process. The first step of this research focuses on understanding the existing decision making process of a food bank. Data from a local food bank was used for this research. Data mining tools were employed to develop predictive models for food bank decision making. Appropriate visualization techniques were identified that can be used to visualize the data mining results. An interactive dashboard was developed and evaluated to enable effective decision making. The results indicated that interactive dashboards were highly effective as compared to the traditional data retrieval system for decision making in food bank operations. The new methodology can be extended to other food banks and hunger-relief organizations which deal with big data.
  • Comparative Assessment of Analytical models for the ULS Resistance
           Verification of Structural Glass Elements under Variable Loads

    • Abstract: The design of glass structures, due to the intrinsic material properties, is mainly governed by the typical tensile brittle behavior of the material. In this regard, a currently open question related to the use of glass in buildings as a load-bearing constructional material, is represented by the correct estimation of static fatigue phenomena due to a generic combination of design actions. In this study, taking advantage of past literature contributions and existing design standards for glass, a novel analytical formulation is proposed for the resistance verification of a given structural glass elements under a Ultimate Limit State (ULS) combination of variable loads. The novel proposal is assessed towards three existing analytical formulations, based on two worked examples as well as an extended analytical analysis. In conclusion, the potential and criticisms of the examined approaches are discussed.
  • Developing and Testing Dynamic Models for HVAC Systems Using System
           Identification Approach

    • Abstract: This paper proposes integrated modeling and optimization methods for a chilled water HVAC system using a system identification approach. Two multiple input-single output models are developed to find the supply air temperature and fan power of the investigated chilled water air handling unit AHU. To test the proposed models, actual data are collected from existing HVAC systems. Different fan and cooling coil model structures with various time delays and orders are tested to find the optimal model structure in term of normalized root-mean-square deviation or Coefficient Of Variances (COV). The paper also proposes an optimization procedure integrated into system identification model to automate the process of finding optimal fan and cooling coil model structures yielding the best accurate predictions. The testing results show that the proposed methods can provide accurate predictions that can used for several applications such as control optimization, energy assessment and fault detection and diagnosis.
