Additive manufacturing, also known as 3D printing, has witnessed a significant surge in popularity and adoption owing to its numerous advantages, particularly its ability to provide high levels of customization. Unlike traditional manufacturing, the process involves creating a 3D object by building it layer by layer, where the material is removed or shaped based on the requirements. This innovative approach to manufacturing has found applications across diverse industries, such as automobiles, robotics, biomedicine, construction, and jewelry. One of its significant benefits is that it does not necessitate specialized tools or machinery, making it more accessible. However, despite its advantages, there are ongoing efforts to enhance additive manufacturing processes by reducing printing time, costs, and material wastage. This investigation focused on optimizing design parameters to achieve these objectives, specifically in the context of a robotic hand. The printing was done using the Aion 500 3D printer after slicing the 3D model (robotic hand) with Cube Pro software. A key strategy employed was to break down the automated hand assembly into manageable parts for printing instead of printing the entire body in one go. This approach minimized complexity and substantially reduced the need for support material during printing. The printing orientation was also optimized to reduce material wastage and the time required. By reducing printing time and material usage, the overall cost of the process was significantly decreased. The calculation considered the material and operating costs per hour multiplied by the printing time. The results of this investigation demonstrated that the optimized design orientation for the robotic arm led to a 30% reduction in printing time, an 18% reduction in material wastage during printing, and an overall cost reduction of 35%. In conclusion, this study showcases the potential for substantial improvements in additive manufacturing processes through strategic design optimization, ultimately enhancing efficiency and cost-effectiveness across various industries.

In this research article, a modified non-uniform adiabatic section a Two-Phase Closed Thermosiphon (TPCT) is proposed where the uniform section was replaced by convergent and divergent (C-D) sections. The deionized water (DI) is filled in both the TPCTs. Further, the heat transfer performance was carried out for three different orientations, such as 0°, 45° and 90°, and heat input was varied from 50 to 250 W. The effect of these geometrical changes and inclination angles on the heat transfer performance of both the TPCT were evaluated to compare the thermal resistance, wall temperature variation and heat transfer coefficient. By introducing the convergent-divergent section nearer to the condenser, the pressure before and after the C-D section was increased and decreased. This enhances the heat transfer in the evaporator about to a percentage at horizontal and 45° orientation, respectively. The thermal resistance of NUAS TPCT was reduced by up to 4.5% relative to UAS TPCT in horizontal and 45°. Several factors such as gravity assistance, fluid accumulation, pressure drop and thermal resistance exert an influence on the heat transfer performance of the proposed NUAS TPCT at various orientation angles. However, different type of cross-sectional variations subjected to orientation changes may also get influenced by several other parameters that in turn affect the heat transfer performance distinctly. Actually a copper coil is rolled over the Two-Phased Closed Thermosiphon (TPCT) which is included with convergent and divergent section. Current (50v, 100v, 150v,200v,250v) is passed through this copper coil to convert electrical energy to heat energy making the flowing fluid (Deionized water (DI)) heat. Our work in this project is to find the amount of energy consumed and amount of energy loss from the input energy by solving in a theoretical way. [ABSTRACT FROM AUTHOR]

The advancement of clinical science and medical service frameworks increments radically. A vast amount of data is generated in our bodies. Hence Ultra Wide Band (UWB) range band 3.1GHz to 10.6GHz plays a vital role in biomedical applications. To build a UWB antenna for off/on body radiation, the following performance criteria are essential such as low Specific Absorption Rate (SAR), low power consumption, Voltage Standing Wave Ratio (VSWR)<2, high bandwidth (BW), high efficiency. The UWB antenna provides a broad range of frequencies with low SAR values. As the quality of power transmission is low, UWB antennas are most suitable for wireless body area networks. Among the various types of antennas, the microstrip patch antennas are widely used in wireless applications. They are generally utilized in remote applications because of their safety, minimal expense, lightweight, and miniature hardware. This paper displays body research worn patch antennas design and development for various applications at the resonant frequency of 5.6 GHz.

The Evaporative cooling system is one of the simplest cooling techniques and an ancient method. It is an eco- friendly cooling system that cools the supply air with the help of water and reduces the temperature. The supply air temperature reduced with the help of two stages of the Evaporative cooling system. The two stages of the Evaporative cooling system are indirect and direct cooling which helps to reduce the dry bulb temperature as well as controlling the humidity of the supply air. The heat transfer in indirect evaporative stage is ineffective and hence in this work we have used graphene. A series of experiments were performed by varying the flowrate of water. From the experimental work, we observed that the use of graphene enhances the performance of the two stage evaporative cooling system. This is due to the higher specific surface area to volume ratio and higher thermal conductivity of the graphene which enhances the heat transfer. The water flowrate was optimised in this work as it significantly affects the efficiency of the evaporative cooling system. [ABSTRACT FROM AUTHOR]

Assertion management has high priority in the construction engineering and management field. It is complicated to completely forbid asserts from appearing in the construction management project and escalating the number of construction assertions designate the necessary for the enactment of a successful construction assertion management. The overall objective of the project is 'to traverse all the major elements donating the cost overrun and recognizing the judgmental elements among them in cost management process and assertion'. Further, various practicing professionals like project managers, consultants and promoters have been interrogated uniquely to get the empirical issues through a survey questionnaire. Findings have been arranged and acceptable methodologies are being used to solve the problems and have been formulated which are appropriate for our Indian Scenario. The findings show that a lack of knowledge of the assertion, inaccessibility or unavailability of relevant records, and disputes that occur during owner/contractor negotiations are all major concerns. Another explanation is that the building industry is unregulated, which means that everyone can work as a contractor. As a result, contract costs are reduced, and job quality suffers.

A windmill uses the energy form the wind to produce mechanical energy. Commonly the windmills are classified into two types based on their axis of rotation as horizontal and vertical axis wind turbines. A vertical axis wind turbine has its main rotor shaft set in transverse to the wind and the other components are fitted at the base of the turbine. This makes repairing and over hauling works easier. Vertical axis windmills does not requires a long tower structures and can be constructed at lower costs and also can be fitted at the house roof tops. In this work the blade design of the vertical axis wind turbines are modified to trap more energy from the available wind and to produce more output. For this the blades were designed in three types such as flat blade, conical and conical with air trappers. Thus the wind mill is tested by fitting the three types of blades one by one and compared for maximum efficiency. Also the number of blades also changed in the order of 2, 3 and 4 blades. Three parameters were found to be the most influencing parameters and the parameters are changed and tested to find out the optimum design. The number of blades, blade design and material of the blade were chosen are the three parameters. Finally it was found that the design with four blades, conical blade with air trappers and fitted with aluminium sheet gives the most efficiency. [ABSTRACT FROM AUTHOR]
