Authors: Lovera Viloria Victor Alfonzo , Sinde Cantorna Sandra
Published: December 2022

La compra pública de innovación (CPI) es una herramienta para promover la innovación desde la demanda pública, la cual está siendo impulsada desde organismos supranacionales e internacionales. Sin embargo, todavía existen pocos casos documentados que muestren ejemplos exitosos que permitan llegar a soluciones innovadoras para retos planteados desde el sector público mediante el diálogo, la cocreación y la compartición de riesgos entre las administraciones y el ecosistema innovador. Esta publicación presenta de manera general el concepto de CPI, sus diferentes tipos y procedimientos de contratación y aborda el problema de la pérdida de energía en hogares de uso social e instalaciones públicas y sus consecuencias dentro del proyecto PAPIRUS. Se trata de un proyecto de CPI con socios en diferentes países de la Unión Europea (UE). En la publicación se detalla la metodología utilizada por parte del líder del consorcio (Tecnalia) para coordinar, planificar, gestionar y evaluar las compras públicas realizadas en cada país, así como los casos nacionales de Alemania, España, Italia y Noruega. Finalmente, se muestra la importancia del estudio y evaluación de impacto de las acciones realizadas. Este caso demuestra que la unión de diferentes administraciones de varios países para la solución de un mismo reto se puede conseguir mediante el apoyo de instituciones como la Comisión Europea.

Published: December 2022

Las Micro, Pequeñas y Medianas Empresas (MiPyMEs) representan un sector de suma importancia para América Latina y el Caribe (ALC). En efecto, el 99.5% de las empresas de la región son MiPyMEs. Estas abarcan el 60% de la población ocupada y generan el 25% del producto interno bruto regional. A pesar de que el empleo informal y el autoempleo en microempresas están muy extendidos en los países de la región, es inevitable reconocer el peso que las MiPyMEs tienen en la economía de ALC. En este punto cabe mencionar que, al estudiar la relación transporte y MiPyMEs, no solo se consideran las MiPyMEs de Transporte, sino que el transporte -per se cumple una función habilitadora para MiPyMEs que pertenecen a otros sectores de la economía. En este sentido, tener una mayor comprensión de estas lógicas es clave para el desarrollo integral de la región.

Authors: Granada Isabel , Altamirano Montoya Álvaro , Saraceno Pier
Published: December 2022

La pandemia del Covid-19 expuso de manifiesto la importancia de las cadenas de abastecimiento en un mundo globalizado. Hoy en día la mayoría de los países sufren fuertes tendencias inflacionarias vinculadas mayormente a interrupciones en las cadenas de suministro de bienes. El alza generalizada de los precios es apenas uno de los efectos económicos de estas disrupciones logísticas. Otros ejemplos incluyen la reducción de inventarios, la carencia de productos de consumo, aumentos en los costos de producción asociados con pérdidas de competitividad en actividades comerciales, rupturas en las cadenas de valor, y mayores barreras para el desarrollo de las empresas de menor tamaño. En América Latina y el Caribe el impacto de la crisis económica derivada de la pandemia fue particularmente agudo, con efectos para el sector de transporte que van más allá de los ámbitos productivos y laborales. Dos años después del inicio de la crisis sanitaria que provocó medidas de distanciamiento social sin precedentes históricos, la recuperación de la actividad sectorial es ampliamente desconocida. Por ejemplo, se desconoce en qué medida los cambios comportamentales de movilidad de personas y de bienes asociados al distanciamiento sanitario persisten a la fecha. También existen vacíos de información relativos a la recuperación del volumen de empleo en el sector de transporte y almacenamiento, el desempeño de esta recuperación relativo a otros sectores de la economía, y sobre la existencia de efectos diferenciados de las distintas modalidades de transporte durante la crisis.

Published: December 2022

The aim of the study is to improve the quality and level of security of an information system for monitoring cargo vehicles at production sites via modern encryption methods, which will provide for accurate management decisions in the event of a system breach. In accordance with modern requirements of information security policies, enhancement of information system security assumes the development of data protection concepts and the implementation of the most advanced encryption methods within the information system. The paper presents the authors’ solution for constructing an information system using SSL-based data encryption, SSL standing for the Secure Socket Layer. The characteristic feature of SSL-based encryption is the creation of a public-key cipher. This enables user and server authentication via digital signature technology. In addition, the method produces a session key that can be used to develop a fast symmetric cipher algorithm that allows encrypting of large arrays of information. Based on the proposed concept, the authors develop an information system for monitoring cargo vehicles at production sites that employs SSL-based encryption.

Development of a Risk-Control Safety Program as an Architectural Contractor Guideline on Flats Project
Authors: Machfudiyanto Rossy Armyn , Latief Yusuf , Fitriani Ratih , Syifa Amira
Published: December 2022

Construction Safety Planning is an element in the CSMS (Construction Safety Management System), which needs to be developed by the Contractor. Irrespective of this condition, the guidelines for preparing a safety program have not been appropriately disseminated by the project owner. This shows that many contractors are yet to appropriately implement the construction safety program. Therefore, this study aims to develop a safety program for Indonesian flat projects, especially architectural work. A qualitative method and secofndary data were used and obtained from a literature review, respectively. This was to determine the breakdown structure of architecture, which was then identified by hazards and operational risks. These processes led to the acquisition of the risk control used in preparing safety program targets, regarding resource analysis. The results showed that the resources needed in this architectural program included safety signs, PPE, warehouse construction, and transportation carts, which should be completed before work inception. In this case, an individual needs to be responsible for all the operational processes, namely the Safety Inspector/Supervisory Officer. These results are expected to be used as a guideline for contractors and project owners, to prepare a safety program and monitor the implementation of CS (construction safety).

Authors: Killi Chandra Bhushana Rao , Balakrishnan Narayanan , Rao Chinta Someswara
Published: December 2022

Fake news is deliberately created with the goal of influencing people and their belief systems. Because false news has a detrimental influence on society and politics, it has become increasingly crucial to identify and stop it from spreading. Most of the prior research has employed supervised learning but has placed emphasis on the terms that were used in the dataset. Initially, we began by pre-processing the information (replacing the missing value, noise removal, tokenization, and stemming). LSTM (long short-term memory network) model is employed for text data classification in this article, and we deal with automated feature selection from text data using the GloVe model. Unlike previous models, the suggested model can select the relevant attributes to determine whether the news is false or real while existing models fail in this regard. The proposed model outperforms the already available models.

Published: December 2022

Samples made of a 1.6 mm thick carbon fiber-reinforced plastic sheet with different curing modes were loaded in the elastic region according to the cantilever bending scheme. Acoustic emission was recorded using an oscilloscope. The microhardness characteristics were used as criteria evaluating the degree of matrix curing which was evaluated on the face surface of the samples and in its cross section at fixed distances from the face surface. Dependences of the frequency, amplitude of acoustic signals, temperature, deflection value and distance to the sample surface on the matrix microhardness were established. The studies showed that the value of matrix microhardness is a relevant criterion evaluating the influence of the mode of carbon fiber-reinforced plastic molding.
On the theory of interaction of related economic systems
Authors: Ilyina Elena A. , Saraev Leonid A.
Published: December 2022

In the published article the process of interaction of several related economic systems, which, on the one hand, compete with each other for fixed assets, the necessary human capital and natural resources is examined. On the other hand, they complement and develop each other and form a single complex within which joint goods are produced, goods, services and financial resources are exchanged, etc. An economic-mathematical model of the dynamics of development and interaction of related economic systems is proposed, taking into account both their competition for resources and their cooperation in the production of joint benefits. This model is a system of non-linear differential equations, which are used to calculate indicators of the dynamics of development of related systems of the economy. The values of these indicators depend on the ratio of investment investments in the production of economic systems and their depreciation deductions for the restoration of resources and costs. The peculiarity of the presented model is that the production function of each economic system containing as arguments not only its own production factors, but also the resources of all other considered related economic entities. It is shown that by controlling the choice of the rates of accumulation of internal investments of economic systems, it is possible to obtain various options for their interaction. With a certain choice of accumulation rates, economic systems can operate independently of each other. Under other norms, some systems of the economy become independent and backbone, while the rest of the systems are subsidized.

Published: December 2022

The article presents an algorithm for choosing mutually agreed management decisions in the implementation of a production project, which allows orienting the interests of the project participants to the interests of the customer in order to increase the efficiency of the project task and the implementation of the project as a whole. The proposed article proposes an economic and mathematical model for choosing mutually agreed management decisions for the "customer-executor" system, taking into account various restrictions. The features of this model are considered, it is shown how an agreed mechanism for stimulating participants in the implementation of the project affects the participants pursuing their goals. Using flowcharts, the actions necessary to ensure the guaranteed result of the customer and the algorithm for the formation of mutually agreed management decisions during the implementation of production projects are shown. A solution to the problem of choosing such coordinated management decisions that will be optimal for all project participants is obtained, taking into account the fact that each of the participants pursues their own goals, which do not always coincide with the goals of the customer. As a result, the scheme proposed in this article for choosing mutually agreed management decisions in the implementation of a production order allows directing the interests of individual project participants to the interests of the customer, thereby increasing the efficiency of the system as a whole.

Strategic planning in energy saving at industrial enterprises of Russia
Authors: Podbornova Ekaterina S.
Published: December 2022

Our country has been and remains one of the leaders in the world's energy industry. Russia's energy needs are fully met by its own resources. Annual export volume of mineral fuel, oil and petroleum products is about 600700 million tons in conventional terms. Currently, the situation with exports is complicated by sanctions and the geopolitical situation in Russia and in the world. Only taking into account the embargo imposed by the U.S., Britain, Australia and Canada, export losses are more than 40 million tons. In addition, Russia is the world leader in proven reserves of natural gas, its volume more than 50 billion cubic meters. At the same time, it should be noted that such high indicators and sufficient resource potential are present at an extremely low level of energy efficiency. Thus, the volume of energy costs for the production of the average Russian producer is about twice as much as the global average. On this basis, the need to improve the quality of strategic planning and to promote targeted activities in the field of energy conservation in industry in the Russian Federation becomes obvious. Such activities will have not only positive economic, but also social, political, environmental and other types of effects. The most energy-consuming branch of industry in Russia is the processing industry, which is about 30 % of all final energy consumption. Another 70% of the energy saving potential is represented by metallurgy, chemical and oil refining and other industries.

Authors: V Bharathi , Ramji B R , Swamy N R Prabhu , Chandra A R Anil
Published: December 2022

Aluminum 6063 alloys are widely used in various engineering and industrial applications since they are highly corrosion resistant and exhibit superior mechanical properties. They are often used in extrusion projects because of their, weldability, moderate strength and good workability. These properties allow them to excel in architectural applications, piping, tubing, general extrusions for medical, automotive, parts profiling, building and construction, recreational equipment and furniture. Investigations revealed that joining of these alloys by conventional welding techniques has several limitations. Friction Stir Welding (FSW) is a highly efficient manufacturing process with improved safety due to absence of toxic fumes or molten spatters and also end products with reduced weld defects, better retention of mechanical properties, less distortion and less residual stress. The present work focuses mainly on the characterization of friction stir welded joints of Al 6063 alloys using reconfigured Vertical Milling Machine. Brinell Hardness, Impact strength & Fractography study of the weldments were carried out to analyze the hardness, impact strength and microstructure of the weld zone and heat affected zone. To justify the impact of contribution of input parameters over the process outcome, Minitab -17 statistical modeling analysis was carried out.
Experimental Investigations to Study the Influence of Thickness and Speed of Aluminum Discs on Brake Parameters with Neodymium – Iron – Boron Magnets
Authors: Krishna G. L. Anantha
Published: December 2022

In the existing friction brakes there are several problems such as squealing, judder, thermal and mechanical failures, disc distortions etc. Hence, in the current work an effort is made to develop contactless braking system using eddy current principles. Aluminum disc along with Neodymium – Iron – Boron (NdFeB) permanent magnets are used for investigations. Thickness of discs considered are 4, 6 and 8 mm. Speeds of disc rotation are equivalent of 75.39 Km/hr, 113 Km/hr, 150.8 Km/hr and 188.5 Km/hr. Considered brake parameters are percentage of reduction in speed, negative acceleration and time consumed. In lone magnet situation with gradual application, higher percentage of reduction in speed, good negative acceleration and less time consumed were observed in 4 mm disc thickness. Hence is suitable for faster train applications. In lone magnet with rapid application situation, superior negative acceleration and lesser time consumed were found in 4 mm disc thickness. This situation is beneficial for high speed automobile applications.

Authors: Kumar K Ashok , Kapilan N. , Kasthurirengan S
Published: December 2022

The ever increasing cooling demand and the environmental concern have made in search of alternative refrigeration and for the last few decades, the energy efficient cooling systems utilizing refrigerants of no negative impact on the environment are explored. In this view, heat-driven refrigeration systems like vapour adsorption refrigeration is one of the favourable alternatives. Though adsorption cooling devices are capable of producing desirable cooling effect with a relatively low heat source temperature, their coefficient of performance (COP) is low in comparison with the existing cooling technologies. Therefore, to solve the environmental, economic and technical issues, the research is still in progress in this area. It is evident from the literature that, the performance of adsorption refrigeration depends on selecting the working pair such as silica gel-water, activated carbon-ammonia, zeolite-water etc. and driving temperature. This paper presents the comparison of performances of solar assisted twin bed adsorption refrigeration which employs silica gel-water and activated carbon-methanol as working pairs. Results are found to be good with continuous cooling in the evaporator using low temperature source of heat and the lowest temperature achieved in the evaporator for silica gel-water is 11°C and for activated Carbon-Methanol is 2°C. The coefficient of performance obtained is higher for silica gel based system than that of Activated carbon based system.

Published: December 2022

Agriculture is the primary source in providing food for the entire nation. Consequently, agriculture is the fundamental origin of food supply. The contributions of agriculture include increase in employment opportunity and economy of the nation. According to IBEF, in India 58% of entire population depends on agriculture as their main occupation. Currently 81.1% of the total agricultural production is produced by livestock farmers. There will be 50% of loss in yield because of pest and disease. The disease in the plant excitants farmers to use unsuitable pesticide which causes unfavorable consequences. This may lead to the reduction in soil and food quality. Besides it has an adverse impact on human life. Nevertheless, farmers are heedless of these effects. The diseases which are naturally created will cause a serious impact on yields also it will bring down the quality of the food and soil. The symptoms which can cause the less yield are infinitesimal and because of the less human vision potentiality it is difficult to recognize the disease. Plant diseases will require genuine identification and proper categorization of the crops. The developed advanced methodology will identify the diseases, percentage of spread area, pesticide name with the quantity of the pesticide require to heal particular disease using image processing technique.
Characterization and Evaluation of Shape Memory Effect of Cu-Zn-Al Shape Memory Alloy
Authors: N Lokesh , Mallik U S , A G Shivasiddaramaiaha , T N Mohith , N Praveen
Published: December 2022

For shape memory applications, Cu-based shape memory alloys have been presented as the “heir apparent” and more cost-effective alternative for NiTi alloys, which have traditionally been used. The variables that have been cited as causes for this forecast includes low material costs, simplicity of fabrication, and good shape memory effect. The essential feature of martensitic phase transitions is the athermal movement of atoms, with no input from diffusion. However, diffusive events may have large effects on relative phase stability, and therefore on transformation temperatures and functional characteristics. Cu-based shape- memory alloys exhibit these behaviours particularly well, with atomic diffusion occurring at room temperature in both the austenite and martensite metastable phases. Nevertheless, it seems that peer- reviewed literature on the same subject is insufficient for accurately quantifying the influence of Zn on Shape Memory Effect (SME) of Cu-Zn-Al Shape Memory Alloy(SMA). Hence in the current study synthesis of Cu-Zn- Al shape memory alloy through liquid metallurgical method using induction furnace and examining the microstructure and phase transformation which is related to SME. The study reveals that for the selected composition the shape memory effect varies from 42- 92% and with increase in Zn wt.% SME found to increase due to conversion of more austenite to martensite.
Comparative Analysis of LUO Converter with and Without MPPT for PV Applications
Authors: K S Bhumika , G Madhumitha , S Priya , Uppara Rajesh
Published: December 2022

Over a decade, power consumption is increasing rapidly due to anonymous tech growth in industry and residential applications. To balance this requirement, generation needs to stair up which in turn unbalances the economy and environment by conventional power generation. A PV panel can be used as a subsidiary source to meet the extra power consumption. Technology still looks backward to extract the maximum power that the panel can generate. MPPT is a solution that can address this issue with an efficient power electronic converter. This paper presents one such - “Luo converter” which works efficiently compared to other market available converters to extract maximum power from a solar panel. The combination of LUO-MPPT results most efficient to extract Maximum Generation from the panel. This concept is validated with the help of MATLAB simulation, considering all ideal conditions in this paper. Analysis of LUO converter with and without MPPT algorithm is also discussed along.

Authors: P Nishanth , M R Haseebuddin , Srinath Pranav , Saleel Naba , Hegde Pannaga , Das A N Mohan
Published: December 2022

An aircraft flying by flapping its wings is called as ornithopter. Ornithopters are called as flapping-wing models and usually built to the size of birds. The wings of the ornithopter generate lift as well as thrust. For the low Reynolds number range, flapping wings are the most efficient means of propulsion, which is why a lot of MAVs (micro aerial vehicles) have flapping wings. They also have the added advantage of better manoeuvrability, as natural flyers such as birds and insects that demonstrate superior flight skills. Ornithopters are used for military applications such as aerial reconnaissance and animal behavioural research since they are made to resemble birds. The present work focuses on the computation of the aerodynamic forces, design and fabrication of an ornithopter. A code is developed to compute the lift, thrust and drag forces generated by the wings using a theoretical model of equations. The design proposed in this study uses a transverse shaft gear system for the power train mechanism to flap the wings. The model was tested and optimizations were done for improving the flight.

Authors: Pamulety T. Chinna , Pillai V. Madhusudanan
Published: December 2022

A supply chain consists of a network of organizations. Each organization in it acts as either customer or supplier to others. Ordering and replenishment decisions of each organization or stage contribute to supply chain performance. A simulation study and experimentation were conducted in this study to determine the impact of ordering decisions on supply chain performance. The ordering decisions at each stage are taken by intuition for experimentation and are taken by inventory policies for simulation. Under customer demand distribution information sharing, the performance of a supply chain is evaluated and compared between those two conditions. A supply chain role play game software package is used to evaluate supply chain performance by intuition, and simulation is used to evaluate different inventory policies. Fixed order policy, Order Up-to Level (OUL), Modified OUL (MOUL), (r, Q) and (r, S) inventory policies are considered in this study. The performance measures used are the total supply chain inventory per period, bullwhip effect and supply chain fill rate. Grey Relational Analysis (GRA) is used to identify the best method to take decisions in supply chain. Results show that supply chain performance is best under MOUL policy. Based on the results of this study, supply chain members are encouraged to identify the best inventory policy and use that rather than making decisions based on intuition.

Silver crystallite-graphene oxide (Ag-Nps/GO) composites are widely used for various applications and are an attractive material for next-generation nano-electronic devices, and we demonstrate their use in humidity sensors. Silver crystallite (Ag-Nps) is prepared through a single step by reduction method at room temperature. The resulting crystallite is a pure phase as confirmed through X-ray diffraction (XRD) without any traces of oxides or secondary impurities. The crystallite size is around 1 μm. These crystallites are blended with synthesized graphene oxide in a different weight ratio to make the composite. Various characterization techniques like scanning electron microscopy (SEM), UV spectroscopy, and XRD are used to understand structures and surface morphology. The composite is dropped on Al printed sensor (IDE). The humidity is varied from 5% to 55%, the conductivity decreases with an increase in humidity. The sensor has a fast response/recovery time reproducible. In conclusion, the present work describes a low-cost, novel strategy for synthesizing humidity sensor applications. The sensors can be used in applications like biomedical, food processing, agriculture, pharmaceutical, and microelectronics.

Nowadays, industries are focusing on developing new materials which must have good durability, bio degradable and with ease of fabrication. For military application, aramid fiber is mostly preferred due to their high impact resistance property. If natural fiber is also combined with aramid fiber then industries can produce biodegradable material. Hence, this paper reviews aramid fiber (Kevlar) composites fabricated with natural fibers. In this paper, the mechanical characteristics of Kevlar composites and various combinations of natural with Kevlar composites have been discussed in detail

Authors: Chandrappa K. , Joshi Anoop
Published: December 2022

Fiber-reinforced polymer composites have a dominating position place in a variety of applications due to the increased specific strength and modulus. C-FRP composite is the most appealing choice for fabricating massive structural bodies like airplanes, automobiles, blades of wind power generation, and so on. SiC-FRP is used in a range of different applications from water pipes or drains coverings to electronic enclosures. Natural fiber derived from plants is gradually replacing synthetic fiber as a reinforcement for polymer composites. One of the key issues with these components is their metallic and electrical properties. Therefore, in this study, atmospheric plasma spray is used to fabricate thick Tungsten Carbide and Chromium Carbide onto C-FRP, SiC-FRP, and natural Bamboo-FRP substrate. Coated specimens were examined for Micro-hardness and Micro-structure. Results showed that the coating has sufficient adhesion strength with drastically improved properties.

Published: December 2022

Linear motion guide ways moves along a predetermined path. Linear Motion guide way features High Positioning, Repeatability, Low Frictional Resistance. Linear Motion guide ways finds wide applications in Aerospace, Automotive, Medical, Pharmaceutical, Machining Tools, Industrial Robots. The stiffness of a Linear Motion guide way is important for the static & dynamic behaviours of machine. The worldwide work focuses stiffness from load and deflection point which in turns help the designers and Machine tool manufacturers to build guide ways for suitable applications. Some studies reveals that the load (Vertical and Horizontal) and deflection in guide ways are having non-linear behaviour. Less work has been done till date considering the non-linear behaviour. Major studies have focussed on Vertical, while few have nominally considered horizontal loading. We wish to present a study considering effect of Vertical, Horizontal and Combined loading on Linear Motion guide ways. We also propose to develop a mathematical model to optimize the stiffness values for Linear Motion guide ways having different rolling elements. Studies done so far reveal clearly that this nature of study has not been undertaken till date and we expect that our work will benefit Research Scholars, Academic Institutes along with designers and Machine tool Manufacturers.

Published: December 2022

Nowadays, composite materials are supplanting conventional materials because of their upgraded properties. Various research works suggest that composite materials have better properties when contrasted with the existing materials that are for the most part utilized in the automotive and aviation sector. This paper proposes the fabrication and investigation of the mechanical properties of ecofriendly waste plastic-based composites. In this work, the essential fortifications in particular are waste polypropylene and nylon 6,6 utilized in various compositions. The composite at different compositions was tested for structural integrity through compressive strength test and Izod impact test, assessed as per ASTM standards. The result shows that the addition of nylon 6,6 as reinforcement along with polypropylene increases the mechanical properties with the highest value of 2.53 kN for the compressive strength test and 4 joules for the Izod impact test.
A Review on Understanding the Crystallization Process of Bioglass in Recent Decade
Authors: Prasad P Shakthi , B M Swetha , S Prakrathi
Published: December 2022

Bioglass is extensively used in clinical and bone tissue engineering, more specifically in orthopaedic as bone substitute in the form of granules or powders because of their excellent bioactivity, biodegradability and biocompatibility. They have the capability to form an integrated bond with bone through degradation and biomineralization at the surface of the living tissues. These activities are mainly driven by the composition, synthesis method and crystallinity of the bioglass. Therefore, in this paper we aimed at reviewing the basics and methods used in assessing the crystallization process of bioglasses and a few insights into crystallization revealed in the recent years. This critical review helps in tailoring and controlling crystallinity for their better applicability.

Published: December 2022

This paper presents the process of developing an aerodynamics package and a suspension system for a Formula SAE race car, with the help of computational methods for the aerodynamics design and analytical methods for the suspension design. Aerodynamics package involving Front and Rear wings and a suspension system involving a strut activated damper with double wishbones is developed. Vehicle parameters such as wheelbase, track width, etc. and the geometry for the front and rear wings are specified by conducting a review of the SAE rule book. 2D CFD simulations are performed on a wide range of high lift low Reynolds number Airfoils at various geometric configurations to select an airfoil configuration with best performance characteristics. 3D models of front and rear wings are made from the data obtained from 2D simulations to conduct 3D simulations of the wings and the entire assembly of the car with and without the wings. A kinematic analysis is performed on the suspension system since it plays a very important role in the dynamics of the vehicle. Data obtained from the aero simulations and suspension analysis is analyzed in a lap time simulator to predict and compare the performance and lap times of the car with and without the aerodynamic package.
