Authors: Torcatoru C , Savescu D 
Published: March 2020

Abstract
Among the current challenges of the global automotive industry include changes in global markets that lead to a variety of products, regulation that drives pressure on new technologies and competition from new competitors. This paper attempts to find answers to the question, how can we capitalize the semi-finished parts of the automotive industry that have emerged from the parameters demanded/imposed by the final customer or which have some visual/design defects, but which retain their functional role. In almost all cases, information and communication technology plays a major role in future strategies to meet the challenges mentioned above, which can stimulate the production process more efficient by using intelligent manufacturing approaches. Thus, this paper proposes to automate and maximize the capitalization of these parts, a Paternoster system for eliminating the logistics/storage space, reducing the handling time, increasing the efficiency and traceability of the scrap

Abstract
Paper deals with the cutting-edge preparation of milling tools by drag finishing. The aim of the experiment was to determine the optimal parameters of the process on a prototype device for edge preparation. The prototype device was based on a 3-axis milling centre and the drag finishing media used was Al2O3 granulating. Tools for the experiment were manufactured on a tool grinding machine Reinecker WZS 60 from the cemented carbide rod with chemical composition WC+Co (10%). After that, the tools were drag finished. Then, cutting edges radii were measured on a Zeiss SURFCOM 5000 surface and form measuring machine. The effect of process parameters such as spindle rotation speed, feed rate and time of the drag finishing on the size of the cutting-edge radius and shape was examined. The experiment design was described as well as measurement and evaluation of the output values. Purpose of the experiment and multi-criteria analysis described in this article was to determine the influence of process parameters on the cutting-edge radius sizes when drag finishing the cemented carbide mills.
Concept for a precise academic Gripper

Published: March 2020

Abstract
A new, precise, scalable multi-purpose gripper system for academic research purposes is proposed. The multi-purpose gripper is intended to be easily adapted to different tasks and object sizes. The gripper system is driven by two separate motor-gear-lead spindle units, operated by a small CNC control. Software running on the CNC unit is completely open source. A novelty for a gripper in this constellation is an interlock-line that may for example be used for a safety door, allowing to stop movement of the gripper fingers and thus being capable to avoid the bruise of an operator’s finger or arm part. This paper describes the steps mechanical parts were designed and simulated to allow a lightweight concept leaving some payload even for relatively small industrial robots used in academic research. Stability of the gripper fingers was tested by pressing the gripper finger towards each other by hand while “blocking” the movement with a finger showing no visible bending effect of the gripper parts. To test the concept of the gripper system, a first prototype is under construction. Parts of the gripper system were simulated, 3D-printed with poly-lactic-acid (PLA) and mounted to a small laboratory robot. The CNC-gripping function will be furthermore optimized and tested at the prototype.
Angle position influences over external magnetic field of a solenoid in wireless power transfer
Authors: Iuga B , Tirnovan R A 
Published: March 2020

Abstract
The general form of the Biot-Savart law is referring to a closed loop of wire, but it can be integrated over a finite length solenoid to calculate the external magnetic field in a specific point, at a rated distance from the centre. The law states that the point of measure must be on the longitudinal axis of the solenoid. In real cases the point of measure has angle orientation in relation to the axis which results in modifications of the field value.

Published: March 2020

Abstract
This study presents the ongoing research conducted in the field of thermal systems which are commonly used in agriculture and also in other fields to utilize the solar thermal energy. This paper describes a small-scale physical system that is controlled by hardware-inthe-loop (HIL) method. The solar thermal input is realized by a heating element, which can provide a 60 W power in total. The input energy is controllable via Pulse Width Modulation (PWM) to mimic the stochastic changes in weather. The heat storage unit is a 1 litre in volume isolated tank, which contains also the heat exchanger unit. The working fluid in this system is water which is forced by custom made peristaltic pumps both on the “collector” side and on the output. In this way the mass flow rate of the pump can be controlled on the heat exchanger and on the user side, as well. The user side is modelled by a water-air heat exchanger forcing cooled air by a varying speed fan. The temperatures are measured on several points of the system which are used to control the flow rates. Experiments were performed with various controlling algorithms in order to find an optimal solution to provide heat for a pig fattener. The recent status of the test results is shown in the case of On-Off and PID control methods in contrary.

Published: March 2020

Abstract
This project showcases the effects of the homogenization treatments applied to 2724 cast aluminium alloy semi-products, as well as the results regarding the resistance and plasticity improvement of these semi-products. These results have proven the validity of the initial processing hypothesis, which states that certain modifications of the crystalline structure can lead to the improvement of the characteristics mentioned above. A highly resistant 2724 aluminium alloy sample, representing the Al-Cu-Mg system, was used for this experiment. At a structural level, the alloy is made of aluminium based solid α solution grains and a series of binary, ternary or complex intermetallic phases that can either be soluble or insoluble. This type of alloy is mostly used in the machine building or aeronautics industry. The results are according to the microstructural observations, the homogenization heat treatment effect leading to the removal of any chemical heterogeneity (dendritic segregation) and a balanced structure made of polyhedral crystals and a homogeneous dispersion throughout the whole mass of the alloy.
Research on the behaviour of the metallic material in the draw-plate while drawing the wire
Authors: Pop E 
Published: March 2020

Abstract
This research introduces the theoretical and experimental study of the plastic deformation through drawing of the copper wire, the presentation of the microstructures resulting after each drawing, certain possible flaws which occur within this plastic deformation process and the conclusions on the grains` flip-over and elongation. During the drawing process, the metallic material undergoes some important transformations in the draw-plate. The equiaxed grains are compressed in transversal direction and elongated in the drawing direction. The wire drawn is hardened due to the elongation of the grains and due to the development of a substructure of dislocations in the deformation grains. The theoretical presentation of the topics in discussion is then followed by a calculation of the reduction and the Δ parameter which causes less unused work if it is low value, limits the cold hardening of the wire and allows the possible execution of a higher total reduction between two annealing processes. A smaller angle for the drawing favours the coating of the lubricant and lengthens the contact area. Thus, a better cooling is obtained for the wire - draw-plate interface and the lubricant film is more stable.

Abstract
In this work, the nanotechnology procedure was utilized to improve both the adhesion force and surface properties of graphene oxide (GO) films. GO has been obtained in a powder form by oxidation purified graphite using the modified Hummer’s technique. Different films of GO nanoparticles (NPs) were deposited using several types of solvents distilled water, acetone, ethanol, dimethyl formamide (DMF) or ethylene glycol. Examination of structural and optical properties of GO films were studied by XRD and UV–vis absorption spectroscopy. Moreover, electrical properties, surface roughness, contact angle, adhesion force, wetting energy and spreading coefficient were investigated. It was observed that the properties of the prepared films are influenced by the solvent type. The electrical resistivity of films is highly dependent on the solvent type which exhibited the lowest value with distilled water. Furthermore, GO film synthesized with distilled water has the best values of adhesion force and average surface roughness (Ra) 143.4 mN/m and ∼ 7.83 μm, respectively. These results are mostly attributed to hydrophilic cites and GO NPs agglomeration in the surface of films and the effects of their size leading to an expansion in the surface roughness.
Size effect of gold nanospheres on the photoacoustic imaging of cancerous cells

Published: March 2020

Abstract
The size effect of gold nanospheres (AuNS) used as a contrast agent for the photoacoustic imaging (PAI) of breast cancer cell line MDA-MB-231 have been assessed for three different sizes and at four optical densities (ODs). The decrease in the AuNS size at the same OD results in an improved PA signal. The PA signal generally increases linearly with increasing OD, with almost the same rate of increase for the three used particle sizes. It is shown that PEGylation of gold nanoparticles (AuNP) decreases the uptake of the particles by the cancerous cell therefore diminishes the PA images whereas clear images are obtained in the case of unPEGylated AuNPs.

Authors: El-Brolossy T. A. , Almutawa A. 
Published: March 2020

Abstract
The development of thermal diffusivity, thermal effusivity and heat capacity per unit volume of polymer nanocomposites, based on PVC filled with different concentration of graphene flakes up to 1.3 vol.% have been investigated using photoacoustic technique. The composites were prepared in the form of thin films with relatively small thickness (23–30 μm). Morphological and structural characterizations of the prepared composite films have been performed using laser confocal microscope, SEM and Raman spectroscopy. The composites exhibit an improvement in both thermal diffusivity (175%) and thermal effusivity (136%) of their values for neat polymer at the highest graphene content used. However, with increasing graphene content no significant variations in the measured values of heat capacity were obtained. The experimental results were analyzed using the mixed model for the thermal conductivity of a two-phase system. We obtained good agreement between our results and the predictions of this model at thermal diffusivity (= (1.5 ± 0.07) × 10−4 m2s−1) and thermal effusivity (= (1.83 ± 0.06) × 104 Ws1/2m−2K−1) of fillers. The predicted thermal diffusivity value of graphene flakes is comparable to the published thermal diffusivity of graphene plates. On the other hand, according to the author’s knowledge, the thermal effusivity of graphene was not previously studied. However, the thermal effusivity predicted in this work is in fair agreement with that estimated using the reported thermal properties data of graphene.

Abstract
Utilization waste material on concrete ingredients or its manufacturing that did not harm the environment is the need for the environment sustainability. It is the background of research in concrete design for more environmental friendly as often called green concrete. This work aims to investigate the usability of the melted slag, obtained from local wrought iron industry, as aggregates replacement according to waste material utilization. In particular, it focused on studying the feasibility of replacing the aggregates using melted slag by investigating the basic physical characteristic. Slag is known have a high percentage of silica and ferric oxides, which gives pozzolanic activities that suitable to use as cement blended product. Slag waste used in this work is obtained from the wrought iron industry from Pakis district, Magelang Regency, Central Java, Indonesia. The slag chunk extracted from the furnace then crushed to smaller particle sizing as fine aggregates and coarse aggregates. The aggregates characteristic is observed in relation to gradation test, specific gravity, bulk density, clay lumps percentage, and Los Angeles abrasion value. All of observation parameters are taken consecutively based on SNI and ASTM specification to evaluate its compatibility as concrete aggregates. The current work remarks that the fine and coarse aggregates generated from wrought iron slag do not reveal complete fulfilment in the aggregate specifications of any standard. Even though, the slag fine aggregates could be used in standard or lightweight concrete with further treatment such as crushing to smaller particle size, washing to minimize the clay lumps, and mixing with natural aggregates.

Abstract
Before being released to the market, software should be screened to ensure that the quality assurance measurement goals have been attained. To achieve this, one of the types of testing sorts is combinatorial testing (CT) aimed at discovering the faults that occur by interacting with the software. A minimization strategy for test cases is indeed important for optimizing test cases and reducing time. As NP hard (where NP is a non-deterministic polynomial) is the problem of generating the minimum test suite of combinatorial interaction testing (CIT). this paper discusses the implementation, and validation of an efficient strategy for t-way testing. The main contribution of the sine cosine algorithm SCA is to show that the strategy was sufficiently competitive as compared to other strategies in terms of the generated test suite size. Unlike most paper. The main contribution of SCA is to show the generation of test data for a high coverage strength (t < 12).

Published: March 2020

Abstract
Main safety requirements in concrete structural are the fire resistance requirements. One of the structural components is Fiber Reinforced Polymer Reinforced Normal Strength Concrete (FRPNSC). FRP reinforcement has been used as the replacement for conventional steel due to anti-corrosion and lightweight characteristics. Severe degradation on chemical bond properties for FRP will be effected when the temperature is rises. It is important to understand the minimum concrete cover thickness and concrete aggregates types to achieve fire resistance requirements. Standard fire equations are commonly used for fire simulations study. However, studies with hydrocarbon (HC) fire equations which fire ignited from petrochemical are limited. Therefore, in order to study the fire resistance of FRPNSC under hydrocarbon fire, temperature at the reinforcement needs to be predicted. In this study, explicit finite difference method (EFDM) used to solve the heat transfer model. The numerical algorithm of EFDM heat transfer model was constructed and used to analyse the concrete thickness and aggregates to achieve fire resistance requirement. The temperature result obtained by the EFDM model successfully validated with test data. FRPNSC under HC for carbonate aggregates give significant effect on the fire resistance compared to standard fire. The carbonate aggregates types also shows better fire performances compared to lightweight aggregates.
